No. significant difference was observed between the moisture regain of the wild silk fibers after degumming. However, there were significant differences in weight loss and moisture regain between cocoon shells as well as shell layers. E. bauhiniae had the lowest weight loss and moisture regain of 23.19 and 5.64%, respectively while G. postica had the highest weight loss and moisture regain, 56.84 and 9.05%, respectively. The SEM micrographs also showed the presence of remnant sericin gum on the fibers surface. In both A. panda and E. bauhiniae, the outer shell layers had the lowest moisture regain and highest weight loss while the inner layer of E. bauhiniae and middle layer of A. panda lost the least weight. The physical structure and chemical composition ofthe cocoon shells and fibers contribute towards the variation in the moisture regain and weight loss and these features may have commercial implications due to their direct effect on the resulting fabric

Nairobi City is underlain by volcanic materials that resulted from the formation of the rift valley. Some of the challenges that face design of structures in the city include: the need to develop structures in areas with poor site conditions; distress in structures that could be related to foundation conditions; encounter of unexpected subsoil conditions even after carrying out some geotechnical investigations, and; development of defects related to adjacent deep excavation. The objectives of this study were: to investigate the qualitative and quantitative properties of subsurface materials, to establish the engineering property variations and to provide properties that represent the best estimates. Information available for this study included; Atterberg limits, grading, consolidation, swell and collapse, triaxial shear and direct shear, point load and unconfined compressive strength. Failure investigation and resistivity survey were carried out to fill the gaps in the available information. The results indicate that the engineering properties of the materials are very variable. Material property variations and the expected performance of the various subsoil materials are provided. The study concluded that before construction, it is necessary to carry out geotechnical investigations to delineate sensitive soils, determine weak and strong spots and evaluate the relationship between total and differential settlements.

Njagi LW, Bebora LC, Nyaga PN, Minga U, Olsen JE. "A Study on Effectiveness of Seven Disinfectants Against Possible Bacteria Contaminants of Coops and Premises Inhabited by Indigenous Chickens and Ducks.". 2005. AbstractWebsite

Seven commonly used disinfectants abbreviated as A, B, C, D, E, F and G (A is, Glutaraldehyde and Coco – benzyl dimethyl ammonium chloride; B is, Didecyldimethyl ammonium bromide 50% w\\v; C is, Sodium hypochlorite; D is, pine disinfectant and antiseptic; E is, chloroxylenol; F is, phenol and that for disinfectant G is, cresol and soap solution) were evaluated for their effectiveness in disinfecting coops and premises of indigenous chickens and ducks. Bacterial isolates from 14 samples (each sample comprising of a pharyngeal and a cloacal swab from one bird pooled together) from village chickens and ducks were used in this study. The isolates were taken to represent microorganisms in the birds\' environment. Results showed that effectiveness amongst the disinfectants varied markedly. Two disinfectants were very effective (sensitivity of 80% and 60% respectively), three were moderate (30% sensitivity, each) and two were ineffective. Some of them were effective only at a concentration higher than that recommended by the manufacturer. For effective disinfection occasional sensitivity testing is therefore recommended.

WAMBUA MRMUASYAISAAC, OKURO DRGUNGASAMSON. "Study on Education and Health of the Under Three year old Children, Ministry of Health, Kenya.". In: CHAKITA. EAEP; 1994. Abstract
The author illustrates how qualitative data from open-ended interviews, pile sorts, and triad sorts can be used to test quantitatively for intracultural variation in norms. Specifically, the author tests whether Gusii men and women in the Suneka Division of Kisii District in southwest Kenya have developed a common set of standards in response to symptoms of malaria. In this small sample, the focus is on internal, rather than external, validity. While the findings about Gusii responses to malaria are not generalizable beyond the village where the data were collected, the method described may be used to study cultural similarities across socioeconomic, gender, and other groups.
WAMBUA MRMUASYAISAAC, OKURO DRGUNGASAMSON. "Study on Education and Health of the Under Three year old Children, Ministry of Health, Kenya.". In: Kenya Adult Education Association. 2003; 1994. Abstract

This paper argues that problems in education are caused by non-professional teachers who are employed when trained teachers move in search of promotion friendly activities or financially rewarding duties. This shift of focus means that policy makers in education act without adequate professional guidance. The problems in education, therefore, result from demands made on mainstream education based on misconceptions about what education can offer. It is argued that the implementation of e-learning in education faces the risk of developing on the basis of unproven theories. This scenario increasingly sees the replacement of formal education activities in institutions of learning with non-formal and informal education practices. Given that the contents and influences of non-formal and informal education are not under the control of the teacher, the experiences that learners bring to education settings are increasingly difficult to manage. The paper proposes that by integrating e-learning in teacher education and rewarding 'good teaching', there is a potential for a successful e-learning revolution in education.

Faculty of Medicine, College of Health Sciences, University of Nairobi, Kenya. Percutaneous transluminal baloon valvuloplasty is currently the treatment of choice for most cases of pulmonary valve stenosis. In the first series of cases performed at Kenyatta National Hospital, six patients aged 4 to 24 years with severe pulmonary valve stenosis and no other associated cardiac lesions were selected for the procedure. Immediately following baloon valvuloplasty, the pressure gradients across pulmonary valve measured by both echo-Doppler technique and cardiac catheterisation dropped very significantly (P < 0.001). Catheterisation peak systolic gradients (psg) dropped from 162.5 +/- 23.7 to 56.5 +/- 19.0 while echo-Doppler pressure gradients dropped from 112.0 +/- 11.9 to 42.8 +/- 16.0. No complications occurred during or after the procedure. This initial short-term experience in our set-up confirms the safety and effectiveness of this procedure. Furthermore, this procedure is much cheaper and technically easier to perform than cardiac surgery. PMID: 8062769 [PubMed - indexed for MEDLINE]

A preliminary study of microbiological quality of honey was carried out using 26 samples obtained from the National Bee Keeping Research Station. Total viable counts (TVC) of aerobic bacteria, yeasts and moulds, and Clostridium species were done. Of the 26 samples, 24 (92.3%) had a TVC ranging from 3 x10 -87 x 10 colony forming units (cfu) per gram of honey. Two samples did not yield any microorganisms. Of the 24 positive samples, 9 (37.5%) were found to contain Clostridium species per gram while eight (33.3%) were positive for moulds with counts ranging from 10-100 c.f.u / g. No yeasts were detected. In addition, three samples yielded the three types of microorganisms.

Nine patients with acute liver failure due to Plasmodium falciparum liver injury admitted to the Rajgarhia Liver Unit of the All-India Institute of Medical Sciences during 1982-84 are presented. The liver was palpable in all the patients, and eight had splenomegaly. Investigations revealed mild to moderate abnormality in liver function tests. All were negative for the markers of acute infection due to hepatitis A and B viruses. Blood film examination showed P. falciparum alone in seven and along with P. vivax in the remaining two patients. Liver histology, which was identical in all eight patients where liver biopsy was done, showed centrizonal necrosis and hyperplastic Kupffer cells loaded with malarial pigment. All the patients recovered with specific anti-malarial and supportive treatment. Our observations suggest that malaria due to P. falciparum may present as jaundice and encephalopathy which stimulates acute hepatic failure due to fulminant hepatitis.
OTIENO PROFMALOJ. "The Study of the Influence of Stochastic Sources in Botzmann Kinetic Equation.". In: Nuovo Cimento 35B, 1,. University of Nairobi Press; 1979. Abstract
OBJECTIVES. The purpose of this study was to identify health-care seeking and related behaviors relevant to controlling sexually transmitted diseases in Kenya. METHODS. A total of 380 patients with sexually transmitted diseases (n = 189 men and 191 women) at eight public clinics were questioned about their health-care seeking and sexual behaviors. RESULTS. Women waited longer than men to attend study clinics and were more likely to continue to have sex while symptomatic. A large proportion of patients had sought treatment previously in both the public and private sectors without relief of symptoms, resulting in delays in presenting to study clinics. For women, being married and giving a recent history of selling sex were both independently associated with continuing to have sex while symptomatic. CONCLUSIONS. Reducing the transmission of sexually transmitted diseases in Kenya will require improved access, particularly for women, to effective health services, preferably at the point of first contact with the health system. It is also critical to encourage people to reduce sexual activity while symptomatic, seek treatment promptly, and increase condom use.
Odero AN. A Study of the Electrical Insulation Characteristics of Woods Locally locally available in Kenya. Nelson I, ed. Nairobi: University of Nairobi; 1993. Abstract

For my thesis I did a problem formulation and then wrote a computer program to help speedily analyze various insulator profiles for use at high voltages. The program when fed the profile would output the potential and electric field patterns around the high voltage insulator, in addition to predicting it's flashover voltage. Validation of the model was obtained through practical measurement in a high voltage laboratory. Profiles that would insulate very high voltages were arrived at this way in a relatively short time.

One hundred children comprising of 57 males and 43 females aged between 8 and 24 months entered the study. 46 children had single and 54 children had multiple helminth infections. All children received albendazole 200 mg (10 ml) suspension as a single dose. Albendazole proved very effective and safe in the treatment of single and multiple helminth infections in children under 2 years of age, achieving cure rates of 100% in both Ascaris lumbricoides and Necator americanus respectively, 83% in Trichuris trichiura and 66% in Hymenolepis nana. Treatment of polyparasitism appears to be of benefit in improving nutritional status using haemoglobin concentrations as an index.

The safety and immunogenicity of plasmid pTHr DNA, modified vaccinia virus Ankara (MVA) human immunodeficiency virus type 1 (HIV-1) vaccine candidates were evaluated in four Phase I clinical trials in Kenya and Uganda. Both vaccines, expressing HIV-1 subtype A gag p24/p17 and a string of CD8 T-cell epitopes (HIVA), were generally safe and well-tolerated. At the dosage levels and intervals tested, the percentage of vaccine recipients with HIV-1-specific cell-mediated immune responses, assessed by a validated ex vivo interferon gamma (IFN-gamma) ELISPOT assay and Cytokine Flow Cytometry (CFC), did not significantly differ from placebo recipients. These trials demonstrated the feasibility of conducting high-quality Phase 1 trials in Africa.
Okong’o PO, Lu YQ. The study of the airway and craniofacial morphology characteristics of individuals with different modified Mallampati scores before orthodontic treatment 正畸治疗前患者的Mallampati评分与气道和颅面形态的相关研究.; 2018. Abstract

Objective:
The aim of this study is to investigate the airway and craniofacial morphology characteristics of individuals with different modified Mallampati scores before they undergo orthodontic treatment.
Materials and Methods:
According to the inclusion criteria, 54 patients (age 15-49 years) were included in the study. The modified Mallampati score of each patient was recorded, and then CBCT and lateral cephalograms of each patient were taken. Cephalometric analysis, CBCT analysis of pharyngeal volumes and transverse jaw dimensions were done for each patient. The patients were stratified into two groups according to their modified Mallampati scores: group 1 (Mallampati I and II); group 2 (Mallampati III and IV). The differences between the two groups were calculated and analysed using descriptive statistics and independent t-test. The relationship between modified Mallampati score and cephalometric morphology, pharyngeal airway volume was analysed using logistic regression analysis.
Results:
The cephalometric analysis results showed that: Maxillary length (ANS-PNS) (p ≤ .05); the perpendicular distance between the hyoid bone and the Mandibular plane (p ≤ .05); the maximum soft palate thickness (p ≤ .05); and lower airway dimension (p ≤ .05) are statistically significantly different between group 1 and group 2. A binary logistic regression identified the perpendicular distance of the hyoid bone from the lower border of the mandible (Hyoid-MP Perp) to be significantly (p < 0.05) and positively related (regression coefficient β =.168) to group membership. The following prediction formula was obtained: probability of belonging to group 2: p = 1 / (1 + exponential (exp)−f), where f = -1.285+0.168x Hyoid-MP Perp.
Conclusion:
Maxillary length (ANS-PNS); the perpendicular distance between the hyoid bone and the Mandibular plane; the maximum soft palate thickness and lower airway dimension may affect the score of Modified Mallampati classification.

Key words: modified Mallampati classification, craniofacial morphology, pharyngeal airway

A Study Of Some Clinical And Laboratory Aspects Of The African Suffering From Duodenal Ulceration.; Submitted. Abstract

This is a prospective study of 50 patients with duodenal
ulcer proved by endoscopy. The clinical and laboratory features
of these patients were analysed and where possible compared to a
group of 30 control subjects.
It was found that a significant number of duodenal ulcer
patients do not present with the classical clinical picture. The
frequency of blood group Q was more in the duodenal ulcer patients as
compared to the controls and duodenal ulcer patients had higher basal
and maximal acid output values. An attempt at interpreting these results
in the Kenyatta Hospital set up has been made.

This report concerns an outbreak that occurred during July/August 1997. Ten pigs from a herd of 181 pigs in a medium-scale, semi-closed piggery in Kiambu District, Kenya, contracted the clinical disease. The main clinical findings in affected pigs included: fever (40.5-41.8 degrees C), prostration, inappetence, dog-sitting posture, abortion, erythema and raised, firm to the touch and easily palpated light pink to dark purple diamond-shaped to square/rectangular spots on the skin around the belly and the back. Based on the pathognomonic skin lesions, a clinical diagnosis of swine erysipelas was made. The diagnosis was confirmed by the isolation of Erysipelothrix rhusiopathiae organisms from the blood and skin biopsies taken from the affected pigs. Response to treatment with a combination of procaine penicillin and dihydrostreptomycin at the dosage rate of 20,000 IU/kg body weight (based on procaine penicillin) for 3 days was good and all the affected pigs recovered fully. The farm was placed under quarantine to prevent spread of the disease

Prognosis is poor and the cost of treatment prohibitive. Conventional radiation and chemotherapy lead to loss of hair, fertility and general weakening of the body`s immune system increasing a patient`s risk to infection. These observations underscore the need for improved, or additional methods of cancer diagnosis and management.

Two hundred and fifty one African children aged 13-15 years were examined for specific intra- and inter-arch malocclusions and tooth loss. The children were from 6 schools randomly selected from 154 primary schools in Nairobi. Overall, 47% of the children were found to have malocclusion, the most frequently encountered anomaly being crowding. Some of the anomalies showed prevalences which differed markedly from those previously reported for American and British Caucasians of comparable age-groups. Nineteen per cent of the children had missing teeth due to caries, 5.6% due to extractions as part of orthodontic treatment and 13% due to other reasons. The mean number of permanent teeth missing due to caries was 0.2, orthodontic treatment 0.1 and due to other reasons 0.2. Almost all the teeth lost as a result of caries were molars and those due to orthodontic indications were premolars. No teeth were recorded as missing due to periodontal disease or trauma. The study indicated a need to exercise caution in trying to relate the numerical values for prevalence of malocclusions in current textbooks to the present population. The results also showed that the proportion of permanent teeth lost was small.

Ongore D. A Study Of Malaria On The Kano Plains, Kisumu District, Kenya: A Community Study Of Currrent Knowledge, Attitudes And Control Practises; Parasite And Spleen Rates; Mosquito Bionomics And The Feasability Of Vector-control At The Community Level.; 1985. Abstract

A Study of Malaria on the Kano Plains, Kisumu District,
Kenya was carried out between April and August, 1985. The
study included the following:-
1. A Knowledge, Attitudes and Practices (KAP) Survey
was conducted, it covered 187 households, representing 20%
of the total households in the study area. The responses
were analysed using the Statistical Packages for the Social
Sciences (SPSS) system on the ICL 2950 computer. In general
knowledge about malaria was found to be good, however knowledge
about the life cycle and habits of the mosquito was
found to be poor. Various plants with possible insecticidal
and/or repellent action were mentioned and are discussed.
2. During a clinical and parasitological survey 1216
people of all ages were examined for malaria parasites and

414 children aged 2-9 years were examined for splenomegaly
as well. Malaria was found to be highly endemic in the area
with an 84.1% parasite rate in children aged 2-9 years ..The

spleen rate in the same age group was found to be 50.2%. The

results and further analysis are given and fully discussed.
3. The Entomological Survey was base¢ upon six selected

collection stations. A total of 599 adult mosquitoes and

424 mosquito larvae were collected. All the import ant local
vectors of malaria were found in the area. In addition many
nuisance mosquitoes and potential arbovirus vectors were
found breeding. The species distribution is analysed and
discussed.

4. The validity of clinicaldiagnosis in malaria was
studied by comparing the clinical and blood film findings
in 1216 subjects. 43 people were found with symptoms
suggestive of clinical malaria. The practical usefulness
of clinical diagnosis is discussed on the basis of these
findings.
5. An Intervention Strategy is described based upon
the survey findings. The feasibility of·vector control at
community level is explored with emphasis on environmental
measures and the use of local resources.

A study of malaria on the Kano Plain, Kisumu District, Western Kenya, was carried out between April and August, 1985. The study included a knowledge, attitudes and practices (K.A.P.) survey on malaria illness and the mosquito vector. Overall knowledge about malaria illness was found to be good. However, treatment and prevention practices of malaria were found to be poor. Knowledge of the mosquito and its relationship to malaria was found to be high. Knowledge of methods of prevention of mosquito bites was also found to be high but actual use of the methods was low. Knowledge of traditional methods of prevention of mosquito bites was also found to be high. Actual use was again found to be low.

Chege MN. A study of how commercial sex workers care for and arrange for future support to their children: case of Kibera, Nairobi.; 2012. Abstract

Childcare is necessary for child survival growth and development. It is influenced by certain factors such as the maternal health status and resource availability. It has been estimated that 50-80% of Kenya's commercial sex workers are HIV positive. They are the primary caregivers for their children. Yet while considerable body of research in Kenya has focused on commercial sex workers as a high-risk group for the fatal HIV/AIDS and on their role in relation to HIV epidemic, no data were available on how they care and plan for future support for their children. This descriptive cross-sectional survey was carried out among 385 commercial sex workers in Kibera Slum in Nairobi Kenya, between July and December 2000. The aim of this study was to evaluate the commercial sex workers' childcare practices and how they plan for future support of their children. The study respondents were women aged between 18 and 19 years. They all had children whose age groups included the 0-18 years. Data were collected over a period of 18 weeks, using a structured questionnaire, observations of the under five years old children, verification of child health card and focus group discussions. Data were analysed using Statistical Package for Social Sciences (SPSS). The results indicated that 81.2% of the study population lived with their children despite the fact that 74.1% practiced prostitution at home. In this study 89.9% of the study population had taken their children to school. However continuous education was undermined by lack of school fees (52.5% and truancy (46.6%) with more of the illiterate mothers (65%) reporting school dropouts. A larger proportion (42.2%) of the respondents who practiced prostitution at home (42.2%) reported more school dropouts of their children than those who practiced elsewhere. Results of health promotion indicated that 96.8% of the under five years old children were fully immunized. More respondents who knew their HIV status discussed HIV/STDs with their children than those that did not know 25.3, p < 0.001). Focus group discussions showed that, health-seeking behaviour for the children was hampered by use of alcohol by the mothers and to some extent, health care cost. Health seeking behaviour for the mothers was significantly associated with respondent's knowledge of own HIV status 6.1, p < 0.05). Support for commercial sex workers in bringing up their children, was minimal. Only 43.9% received support from extended families. The illiterate mothers were less likely to be supported by relative (OR 2.64, p < 0.01). Possession of assets was positively associated with having an extra income generating activity 17.8, p < 0.001). Those respondents with secondary education were more likely to possess assets for future support of their children compared to those without (OR 1.9, p < 0.05). Generally, the commercial sex workers of Kibera slums made no provisions for future support of their children. Alcohol consumption and low education undermined their efforts to provide better care to their children and to secure resources. This underlines the need for continuous health education among commercial sex workers and establishment of systems that will assist them to invest in the education of their children.

Swazuri MA. A study of housing needs assessment a case study of Malindi town .; 1986. Abstract

The gap between what amount of housing is available and the desired housing level represents housing need. Investigations have shown that this need is growing over time, with little in the form of more housing being provided. In order to gauge by how far this need is being satisfied, it is necessary to undertake some study of housing needs in an area. This project work comprises a study of methods for estimating overall housing needs. Prevailing theories of housing need have concentrated very much on the physical housing product itself as a representation of what and how much housing is required. Some of these theories and their practical applications in estimating housing needs are investigated. The results of most of these methods point out that the housing problem in many developing countries is one of unmanageable proportions, and that the needs have in many cases been measured unconvincingly. These methods have been applied to the study area of Malindi Town in the Coast Province of Kenya. The results of the study reveal the deficiencies in the current assessment methods. Any proper method for estimating housing needs should consider important elements like the environmental quality of the houses and their surrounding neighborhoods. It should also consider the level of housing services and peoples cultures that are necessary for the decent living of the occupants, whether these occupants can or cannot afford these essentials. The proposed model in this study incorporates a methodology for assessing housing needs in the light of the above prerequisites, which have often been neglected in the current housing need estimates. Though without fault, the method at least tries to reduce some of the defects inherent in the prevailing methods for estimating housing needs. There are three main parts to the study. First, housing needs are discussed in relation to current theories and methods of measuring them. Models are given and analysed against the magnitude of the housing problem as portrayed by other analysts. The second part is about the study area, Malindi Town in Coast Province, in which the various methods have been applied in order to test the hypothesis and carry out aims of the study. Data on population trends, household sizes, income structures, building materials, housing information .and construction activities are presented and analysed to provide a basis for the estimations. The third section links parts one and two in actual housing needs estimation using data obtained from a field survey. This section winds up with summary and recommendations obtained from the results of the estimations. Housing needs should not be assessed literayfor, they involve more than what meets the eye and more often they should be measured in recognition of the society's housing norms and allied attitudes

"The study of HIV and antenatal care integration in pregnancy in Kenya: design, methods, and baseline results of a cluster-randomized controlled trial.". 2012. Abstractpone.0044181.pdf

Despite strong evidence for the effectiveness of anti-retroviral therapy for improving the health of women living with HIV and for the prevention of mother-to-child transmission (PMTCT), HIV persists as a major maternal and child health problem in sub-Saharan Africa. In most settings antenatal care (ANC) services and HIV treatment services are offered in separate clinics. Integrating these services may result in better uptake of services, reduction of the time to treatment initiation, better adherence, and reduction of stigma.A prospective cluster randomized controlled trial design was used to evaluate the effects of integrating HIV treatment into ANC clinics at government health facilities in rural Kenya. Twelve facilities were randomized to provide either fully integrated services (ANC, PMTCT, and HIV treatment services all delivered in the ANC clinic) or non-integrated services (ANC clinics provided ANC and basic PMTCT services and referred clients to a separate HIV clinic for HIV treatment). During June 2009- March 2011, 1,172 HIV-positive pregnant women were enrolled in the study. The main study outcomes are rates of maternal enrollment in HIV care and treatment, infant HIV testing uptake, and HIV-free infant survival. Baseline results revealed that the intervention and control cohorts were similar with respect to socio-demographics, male partner HIV testing, sero-discordance of the couple, obstetric history, baseline CD4 count, and WHO Stage. Challenges faced while conducting this trial at low-resource rural health facilities included frequent staff turnover, stock-outs of essential supplies, transportation challenges, and changes in national guidelines. This is the first randomized trial of ANC and HIV service integration to be conducted in rural Africa. It is expected that the study will provide critical evidence regarding the implementation and effectiveness of this service delivery strategy, with important implications for programs striving to eliminate vertical transmission of HIV and improve maternal health.

Eighty random patients were examined over a 9-month-period to determine the incidence of asymptomatic haemorrhoids at the Kenyatta National Hospital (KNH). The incidence of asymptomatic was found to be 21% all being first degree haemorrhoids, while in the age group 50 years and over, 29% had asymptomatic haemorrhoids. The mean age calculated as 44.3 years (+/- 18.3), with no statistical difference between the ages of the two sexes. Males however had a significant greater incidence of asymptomatic haemorrhoids than females.
Arimi SM, Fricker CR, Park RWA. "Study of haemolytic activity of some Campylobacter spp. on blood agar plates.". 1990. Abstract

A total of 152 strains of Campylobacter jejuni, C. coli, C. laridis and C. fetus subsp. fetus were tested for haemolysis on blood agar plates. Distinct haemolysis was detected in 92.% (96/104) of strains of C. jejuni and 21.7% (5/23) of strains of C. coli on sheep blood heart infusion agar after incubation for 4 d microacrobically at 42°C. Haemolysis was also detected on horse blood heart infusion agar. Haemolysis was not detected at 37°C except with one of 50 strains of C. jejuni tested at this temperature, which was weakly positive. Campylobacter laridis was not haemolytic; C. fetus subsp. fetus, which does not grow at 42°C, showed no haemolysis at 37°C. Blood agar (Oxoid, BA Base No. 2) was not suitable for testing for haemolysis by these organisms. A microaerobic gas mixture containing hydrogen is better than that containing nitrogen because the medium has a brighter colour, making haemolysis casier to detect. There was no synergistic haemolysis with Staphylococcus aureus or Streptococcus agalactiae. The plate haemolysis test as described here may aid differentiation within the thermophilic campylobacters

Dr. Joshua Okumbe, Dr. Gerald Kimani (Eds.). A study of factors which influence performance in Kenya Certificate of Secondary Education in selected public secondary schools in Nairobi and Central Provinces.. NAIROBI: UNIVERSITY OF NAIROBI; 1999. Abstract

The Purpose of this study was to investigate the factors that influence performance in Kenya Certificate of Secondary Examination in selected secondary schools in Nairobi and Central Provinces. The research was intended to find out whether good academic performance could be attributed to specific factors that are present in the schools performing relatively better. The major factor considered in this study KCSE performance. The literature review was divided into four subheadings: effect of school-related factors on academic performance, effect of non-school factors on academic performance, effect of student-related factors on performance and effect of motivational factors on performance. From the literature review, a conceptual framework was designed. The conceptual framework showed variables (inputs) and their expected directional effect on each other on the outputs (performance). The study used expost facto research design. The sample consisted of 32 headteachers, 575 teachers and 773 students. The data was analyzed and interpreted using descriptive statistics and the chi-square statistical test which was accompanied by a contingency coefficient. The study revealed that there was a significant relationship between the condition of school facilities, as perceived by headteachers, and students’ academic performance in KCSE. The study also revealed that students’ KCPE entry marks, headteachers’ frequency of holding staff meetings, students’ socioeconomic background, teachers academic qualification, teachers’ workload, involvement of teachers in administrative decision-making, method used to solve teachers’ problems, headteachers’ frequency of holding meetings with parents, frequency of headteachers’ meetings with form four students, teachers’ attendance of in-service training and promptness of school fees payment were significant in determining KCSE performance. The factors that were not found to be statistically significant in determining KCSE performance were teaching of extra hours and reinforcement by parents on their children. Based on these findings it was recommended that there is need for headteachers to hold frequent staff meetings in which problems and progress of the school could be discussed. It was also recommended that there is need to encourage bursary schemes to cater for students who come from low socioeconomic background. Finally it was recommended that there is need for headteachers to involve parents in school activities and need to convert day schools into boarding schools.

Oduor R. A study of factors causing inadequacy of production of building materials in Kenya .; 1991. Abstract

Many construction industries in developing countries are said to experience serious difficulties in their operations, with inadequate supply 01 building materials ranking high in the list of ills. In Kenya over the years, the industry has also experienced a lair share of problems which have included shortages and at times complete disappearance of certain buikling materials. Shortages of building materials are not desirable as they can lead to disruptions in building programmes and at times complete abandonment of projects. The main objective 01 the study was therefore to investigate the cause of the building materials industry's inability to satisfy demand placed on it. Descriptive survey method formed the basis of the study. The study was thus approached in two ways. Through library research. in chapters one and two. the study analyzed and discussed the structure, organization and the market forces that form and create the economic environment upon which the industry operates. This analysis whilst providing a theoretical background 'for the study also conceived a model that exposed the amenability of the industry to targeting the national development planners. The aforementioned exercise also took into consideration the significant role played by the industry in socio-economic development and welfare of the nation. The second objective 01 the study involved the examination of the effect of the existing government policies. regulations and the implementing institutions on the industry's activities against the generally expressed goals 01 the policies. This objective was carried out hy the use of questionnaires served to building materials manufacturing firms. The aim was to obtain firsthand information and experiences of the manufacturers on the problems beleaguering their operations.

Kingsford R. A STUDY OF EMPTY CONTAINERS MANAGEMENT BY LOGISTICS FIRMS IN MOMBASA. Nairobi: University of Nairobi; 2007. Abstract

The study had two major objectives. The first objective sought to investigate the current empty container logistics management practices by logistics firms in Mombasa. The second objective was geared to investigate and determine the challenges facing empty container logistics firms in Mombasa. Data was gathered mainly through semi-structured questionnaires and interviews. Content analysis as a method of data analysis was widely used in the analysis of the data collected. Charts and Tables were also used in the presentation and analysis of the data. The findings of this study have brought out pertinent issues. Through the analysis of the data collected it was noted that there is a short fall in practices by logistics firms logistics firms in Mombasa compared to practices found elsewhere in the world and therefore the potential for improvements largely untapped. It was also found that the customers always bear the bulk of the costs, even those associated with the logistics firm's inefficiencies. Several challenges and remedies were identified. The empty containers turnaround time was identified as a key impediment because of poor infrastructural and poor management and workmanship. Management of empty container fleet was cited as a big challenge in many empty container logistics firms by many of the respondents. Other challenges identified include poor handling equipment, Shortage of storage within the port and at the empty container logistics centers, Long distance between the port and container depots, High tariffs and fees charged on empty container storage, Lack of a standardized tracking and security systems, Poor container stacking procedures at the port among others. The findings and the recommendations of this study will be of great use to the empty containers logistics players and the policy makers in the future development and enhancement of the logistics sector in Mombasa. The experiences can also be used in other regions

The analysis of environmental emissions from the biomass fuel was done through tracing of the elemental concentration of two crucial alkali earth metals (potassium and calcium), four transition elements responsible for pollution (zinc, copper, manganese and iron), one heavy metal (lead), six trace elements (rubidium, strontium, yttrium ,Germanium, zirconium and niobium), nitrogen, phosphorus and one halogen gas (bromine) by colorimetric analysis (N-P-K), and XRF (all other elements). The elemental concentrations was analyzed in the waste flowers, compact pelletized biomass carbonized fuel and ash residue.. Concentrations of the element lead in ash implies higher than normal amount of what is expected of bottom ash, but comparable to concentrations found in fly ash of woody biomass fuels. NPK analysis suggests that chamomile biomass flowers found at Kibwezi are high in potassium (3.5%) and nitrogen content (2.6%).

Ndetei DM, Khasakhala L, Ong’echa FA, Kokonya D, Mutiso V, Kuria M, Odhiambo G, Akanga S. "A study of drug use in five urban centres in kenya.". 2008. Abstract

Few studies have addressed the reasons for substance use in Kenya, with most focusing on prevalence rates in school-based and general population samples. None have been carried out among people already using drugs. This study, based on five samples of drug users, aimed to identify patterns of factors contributing to and consequences of substance use; compare socio-demographic characteristics; document help-seeking behaviours of substance abusers as well as their family and social dynamics. Active or former substance abusers (N =1,420) were interviewed using a structured questionnaire format. The peak age for substance abuse was between 21 and 30 years and most abusers were male. Leisure, stress and peer pressure were the most common reasons given for abusing substances. There were negative economic and work-related impacts of abusing substances. Risky sexual behaviour may have been a consequenc of abusing substances. Substance abusers need assistance as most of them could benefit from programmes for treatment and rehabilitation.

Seventeen cows of various breeds with varying degrees of severity of advanced ocular squamous cell carcinoma were treated by radical surgery, which included enucleation and extirpation of the surrounding ocular muscles and tissues. The degree of severity and the extent of the carcinoma lesion was correlated with the outcome of treatment for each case. It was observed that: 1. eyeball involvement, 2. ulceration and subsequent infection of carcinoma lesion involving the eyelids and 3. involvement of the regional lymphnodes especially the parotid , are some of the main factors that could be used to draw prognosis of such cases. Although the initial surgery may not be costly, the overall cost of managing postoperative complications is prohibitive and results to vast economic losses that should not be ignored.

Although military conflicts are common on the African continent, there is a paucity of data regarding bomb-blast injuries in this region and in Kenya in particular. This paper describes the pattern of maxillofacial injuries sustained after the August 1998 bomb blast that occurred in Nairobi, Kenya. A retrospective cross-sectional study was carried out using hospital-based records of 290 bomb-blast survivors admitted at the Kenyatta National Referral and Teaching Hospital in Nairobi. Using a self-designed form to record information about variables such as the sex and age of the survivors and type of location of soft- and hard-tissue injuries, it was found that of the 290 bomb-blast survivors, 78% had sustained one or more maxillofacial injuries. Soft-tissue injuries (cuts, lacerations or bruises) were the most common, constituting 61.3% of all injuries in the maxillofacial region; 27.6% had severe eye injuries, while 1.4% had fractures in the cranio-facial region. This paper concludes that the effective management of bomb-blast injuries as well as those caused by other types of disaster requires a multidisciplinary approach. The high percentage of maxillofacial injuries confirm that maxillofacial surgeons should form an integral part of this multidisciplinary team.
Kwasa TOO. A Study Of Clinical And Laboratory Features In Stroke Patients At The Kenyatta National Hospital..; 1987. Abstract

This is both a retrospective as well as a prospective study conducted from January 1986 to January, 1987 at KNH involving 72 stroke patients.
Thirty point four per cent of the patients were found to hypertensive. The majority were found to be from the Central Province- More patients were rural dwellers than urban dwellers. The majority y of the hypertensive patients were either first diagnosed at admission for stroke or had had poor control of their hypertension, Most hypertensive
patients were old, (> 45 years).
Laboratory investigations showed hypertriglyceridemia, hyperuricemia, renal insufficiency, and high ESR to be common amongst stroke patients. Syphilis was not found in any of the patients.
The young normotensive patients were examined and some possible aetiological factor identified in all except four.
Recommendations are made as to' further work
and prevention against stroke.

Energy has become a very important aspect of our lives. This study has tried to examine the problems related to energy use, and has tried to outline various measures that can be effectively used to improve energy utilization in the student hostels. Energy use in buildings is discussed with emphasis laid on the need to incorporate energy as a design parameter at the design stage. Energy management for old buildings is also examined with the aim of showing that effective and efficient energy management is a key factor in reducing energy consumption in buildings. The research tries to bring out the nature of energy consumption in the student hostels. This is done with the aim of identifying energy conservation opportunities. Finally the study has outlined various conclusions and recommendations, that if applied could possibly help in reducing the high energy consumption in the student hostels

Material came from 19 patients with invasive cervical carcinoma admitted to Kenyatta National Hospital. A control group consisted of 20 women matched for age who attended clinics at the hospital but were not suffering from any malignant disease; control tissue for histological examination was obtained from 3 women who had undergone hysterectomy for uterine fibroids. Biochemical assays for alkaline and acid phosphatases in patients with cervical carcinoma show an increase in alkaline phosphatase in carcinomatous tissue (35.7 umoles/hr/mg) as opposed to normal tissue (7.2). Acid phosphatase values were only moderately raised. Assays of the same enzymes in blood showed a less marked difference between patients and controls (ranges of 7.5-20.8 and 3-14, respectively). When examined histochemically, increased alkaline phosphatase activity was observed in connective tissue, epithelium of the glands and blood capillaries of tumor tissue. 1 section containing normal tissue bordering carcinomatous tissue demonstrated normal alkaline phosphatase activity in the normal tissue and increased activity in the tumor tissue. In summary, there is increased enzyme activity around the tumor areas, but values for serum levels show an overlap of normal and abnormal cases and are therefore not predictive. Results demonstrate a clear difference in activities of these enzymes in carcinomatous tissue and normal tissue, which may be of value in follow-up care.

This study set out to examine the policy position in Kenyan health care financing, with regard to implementation of the proposed social health scheme (NSHIF) and its performance potential. The specific objectives were to: examine the existing social scheme (NHIF), its role and challenges in health care financing; establish whether or not Kenya has the key pre-requisites for introduction and sustainability of a social health scheme and to provide recommendations on the way forward. This was largely a desk study, supplemented with limited primary data from key informants. The analysis indicates that: i) For a universal social health plan to be sustainable, favorable economic indicators and availability of essential infrastructures are critical prerequisites. Resources must be available, government must be in a position to afford high subsidies, the population must be ready to pay high premiums and the supply of health services must be adequate to cater for the expected increase in demand; ii) Countries that have successfully embraced social health plans introduced their schemes carefully and gradually (overtime) in terms of coverage; iii) Kenya compares unfavorably with these countries in terms of prerequisites for sustainability of a social health scheme, due largely to a poor economy, high poverty levels and shortfalls in facilities and services. The study concludes that Kenya lacks the key prerequisites for introducing and sustaining a universal social health scheme. The scheme can hardly be supported by the current status of the economy and healthcare infrastructures. The study recommends: i) Expansion and development of health care infrastructural capacities through subsidies and tax concessions for those investing in health care and providing subsidized services, particularly to the poor and rehabilitation of the GoK facilities; ii) Increasing the health budget from 7 per cent of government expenditure to above 10 per cent and directing more resources and efforts towards preventive/promotive and primary health care (P&PH); and iii) Other recommendations include subjecting the proposed scheme to an actuarial evaluation and comprehensive policy plan in order to determine the attendant and corresponding premium and benefit levels and pursuing a phased approach in the implementation of the scheme.
Mbuya TO. studies on the microstructure and mechanical properties of recycled cast aluminium scrap .; 2003. Abstract

The aluminium casting industry in Kenya is strongly dependent on aluminium scrap recycling. There is, however, little organised information on appropriate recycling procedures and the expected chemical composition of the resulting secondary alloys. Furthermore. little is also , known on the expected mechanical properties of castings produced from the secondary alloys . under different processing conditions. Consequently, the quality of locally produced castings is poor compared to their imported counterparts as most Kenyan foundries rely on chance to make good castings. The main objectives of this preliminary study were: (a) to determine the chemical composition of the secondary alloys obtained from recycling various cast aluminium scrap components available in Kenya; and (b) to determine the microstructure, tensile strength. percent elongation and hardness obtainable from these alloys using both green sand and permanent mould casting processes and under different process conditions. The process parameters for both green sand and permanent mould casting processes, whose influence on the said properties was investigated . are: the type of mould filling system, melt handling and pouring temperature. The influence of the thickness and initial temperature of permanent moulds on these properties was also investigated. It was found in this study that the common types of scrap components available in Kenya are automotive engine parts. Most of these components were found to be pistons, cylinder heads, gearbox housings and to a lesser extent, rear axle housings. Pistons and cylinder heads were classified as individual groups while gearbox and rear axle housings were grouped together. The rest of the scrap items, most of which could not be identified, were lumped together to form another separate group. Samples were randomly picked from these scrap groups and • individually remelted to obtain secondary alloys. Other secondary alloys were also prepared by • blending the above scrap groups in predetermined proportions. • The resulting secondary alloys from these groups of scrap •c9mponents were all hypoeutectic aluminium-silicon-copper (AI-Si-Cu) based alloys. The samples in similar scrap groups were v \. < fairly equivalent in chemical composition although some minor variations were observed. Some samples from different groups were also found to be fairly equivalent In their chemical composition. Furthermore, all the samples were also fairly equivalent. In their chemical composition, to several common commercial hypoeutectic AI-Si-Cu based alloys. Permanent mould casting resulted in castings with higher tensile strength, percent elongation and hardness compared to green sand casting in all scrap samples tested. Both quiescent melt handling and quiescent bottom filled mould systems yielded castings with higher aforementioned properties than turbulent melt handling and turbulent top filled mould systems . . respectively. In addition, these mechanical properties were found to decrease with increasing pouring temperature and mould preheat. Increasing the mould thickness was, however, found to increase these mechanical properties. Heat treatment of some of the alloys to the T6 condition increased their tensile strength and hardness, but decreased their percent elongation. The microstructure of all the recycled alloys was typically similar and contained cc-aluminium matrix, eutectic silicon particles, iron-bearing and copper-bearing intermetallics. The tensile strength and percent elongation of the recycled alloys did not correlate well with those of their respective commercial counterparts. This was particularly so with top filled green sand castings. The mechanical properties of bottom filled samples were. however. closer to those of their commercial counterparts albeit falling on the lower end in the range of reported . mechanical properties of their respective equivalent commercial alloys. The hardness values of the samples, however, correlated well with those of their commercial counterparts. It is inferred from the results of this study that using the type of scrap component as the sorting criterion is of limited usefulness because some samples cast from different scrap components were fairly equivalent in their chemical composition. Furthermore. some scrap items are either too few to recycle separately and/or difficult to identify. However, in the absence of appropriate facilities to determine the alloy chemistry on-line and make appropriate melt corrections. this sorting criterion together with the chemical compositions of the samples studied in this study can be a useful guide. Also inferred is that blending scrap samples is not useful because no . definite trend in the chemical composition was observed with blending. Finally the processing conditions strongly influenced the mechanical properties of the samples . . It is therefore important to choose the right casting process and to closely control the mould design, molten metal processing and other process parameters like pouring temperature and initial mould temperatures in permanent mould casting. In particular. permanent mould casting should be preferred to green sand casting if maximising mechanical properties is the major factor for process selection. In addition, mould filling systems should be skilfully designed to quiescently introduce molten metal into the mould cavity preferably via bottom filling. The pouring temperature should also be as low as possible.

Lore T. Studies on the microflora in suusac, a Kenyan traditional fermented camel milk product. K. MS, J. W, eds. University of Nairobi; 2004. Abstract

The purpose of the study was to determine the lactic acid bacteria (LAB)and yeasts
associated with the traditional fermented camel milk product (suusac) of the Somali
community in Kenya. The traditional method of suusac production was studied by use
of questionnaire and documented. The microbial content profile and changes during
fermentation were then determined.
From 15 samples of traditionally fermented suusac, 45 LABand 30 yeast strains were
isolated ~d identified using API 50 CHL and API 20C AUXidentification systems,
respectively. The total viable microorganisms, LAB,coliforms, and yeasts and molds
were enumerated. The isolates were investigated for their functional roles in the
fermentation process, namely, acidification, flavour/aroma production and proteolytic
activity. Fermentation trials with single and mixed strain cultures were investigated to
assess their acidification and flavour-producing properties.
The traditional production of suusac involves spontaneous fermentation of camel milk
in smoked gourds at ambient temperature for 1-2 days. The milk is not subjected to
heat treatment prior to fermentation. The isolated LAB species were identified as
Lactobacillus curvatus (8% of total isolates), Lactobacillus plantarum (16%), Lactobacillus
soliuarius (8%), Lactococcus raffinolactis (4%) and Leuconostoc mesenteroides subsp.
mesenteroides (24%). The isolated yeasts were Candida krusei (20%), Geotrichum
penicillatum (12%) and Rhodotorula mucilaginosa (8%). In traditional suusac, LAB
counts averaged 6.77 logrocfu Zml, while yeast counts were relatively lower (2.05
log.ocfuZml]. Low coliform numbers were encountered « 1 log cfu /rnl].
The LAB produced considerable acidity and majority (60%) were homofermentative.
The primary functional role of the LAB was fermentation of lactose to lactic acid,
resulting in acidity levels ranging from 0.46-0.67% lactic acid equivalent. All the LAB
isolates recorded high proteolytic activity, except for L. raffinolactis, which did not
exhibit any proteolytic activity. The LAB showed varying degrees of diacetyl
production. Of the LAB, L. curvatus recorded the highest diacetyl flavour score,
corresponding to >30 mg diacetyl/ 100 ml of milk.
The yeast isolates showed limited carbohydrate-assimilating capabilities, but played a
role in flavour development and proteolysis. G. penicillatum produced diacetyl (3.1-10
mg/lOO ml), although it did not exhibit any proteolytic activity. C. krusei exhibited
some proteolytic activity, although its diacetyl-producing capacity in camel milk was
minimal (0.5-3 mg/ 100 ml).
C. krusei also played a role in mixed starter fermentation of camel milk by increasing
the activity of the LAB cultures and improving product flavour. The use of C. krusei +
1. plantarum (1: 1) and C. krusei + L. curvatus (1: 1) reduced the fermentation time by
half as compared to the use of the cultures individually.

The vision of the Government of Kenya is to facilitate ICT as a universal tool for education and training. In order to achieve this vision every educational institution, teacher, learner and the respective community should be equipped with appropriate ICT infrastructure, competencies and policies for usage and progress. It calls for recognition of the fact that ICT provides capabilities and skills needed for a knowledge-based economy. It also calls for transforming teaching and learning to incorporate new pedagogies that are appropriate for the 21st  century. The Ministry of Education�s (MOE) mission is to facilitate effective use of ICT to improve access, learning and administration in delivery education programmes and services. The principal objective will be to integrate ICT in the delivery of education and training curricula. XML:NAMESPACE PREFIX = O />  Although not exhaustive, the range of ICT that have been used in the delivery of education to improve access, teaching, learning, and administration includes: Electric Board, Audio Cassette, Radio for Interactive Radio Instructions (IRI), Video/TV-Learning, Computer, Integrated ICT infrastructure and Support Application Systems (SAS).These systems are in use, at various degrees, in most parts of Africa (Charp, 1998). This plan envisages use ofthese digital components to improve access and quality in the delivery of education in Kenya.  The major challenge in respect to this component is limited digital equipment at virtually all levels of education. While the average access rate is one computer to 15 students in most of the developed countries, the access rate in Kenya is approximately one computer to 150 students (EMIS, 2005). Whereas most secondary schools in Kenya have some computer equipment, only a small fraction is equipped with basic ICT infrastructure. In most cases equipment of schools with ICT infrastructure has been through initiatives supported by the parents, government, development agencies and the private sector, including the NEPAD E-Schools programme. Attempts to set up basic ICT infrastructure in primary schools are almost negligible.  According to ICTs in Education Options Paper, one of the main problems is limited penetration of the physical telecommunication infrastructure into rural and low-income areas. Specifically, the main challenge is limited access to dedicated phone lines and high-speed systems or connectivity to access e-mail and Internet resources. The EMIS Survey (2003/2004) indicated that over 70% of secondary schools and a much larger proportion of primary schools require functional telephones. Indeed, many parts of Kenya cannot easily get Internet services because of the poor telephone networks. About 90% of secondary schools need to establish standard Local Area Networks (LANs) in order to improve sharing of learning resources.  Alternative and appropriate technologies for access to Internet resources, including wireless systems remain quite expensive. Indeed, a small proportion of schools have direct access, through Internet Service Providers (ISPs), to high-speed data and communication systems. Furthermore, very few schools in the rural areas use wireless technology such as VSAT to access e-mail and Internet resources. Nearly all of the 6 NEPAD e-Schools are in rural areas and are expected to enjoy internet connectivity through VSAT technology.  While other countries have reported up to 41% of integration of ICT to teaching and learning, the proportion remains substantially low in Africa, Kenya included. Integration aims at the use ICT to support teaching and learning in the delivery of the various curricula to achieve improved education outcomes. Because ICT is interactive media, it facilitates students to develop diversified skills needed for industrialization and a knowledge-based economy. It also allows teachers and learners to proceed at different paces depending on the prevailing circumstances. As a first step, the Ministry of Education has initiated a major ICT project in Secondary schools meant to equip over 200 secondary schools with ICT infrastructure for integration of ICT in teaching/learning process ( KESSP, 2004). Three schools have been chosen in every district of Kenya.
Ateka EM, Kimenju JW. "Studies On The Interaction Between Ralstonia solanacearum (Smith) And Meloidogyne Spp. In Potato.". 2001. AbstractWebsite

A survey was undertaken to determine population density of Meloidogyne juveniles (J2) in 90 fields randomly selected from three potato-producing districts in Kenya namely Nyeri, Meru and Nyandarua. Mean nematode densities were highest (45) in samples collected from Nyeri and Nyandarua and lowest (31) in soil samples collected from Meru. The reaction of 15 potato cultivars to Meloidogyne incognita was determined under greenhouse conditions. Plants were inoculated with 6000 eggs and second-stage juveniles each. Highly significant (P=0.01) differences were observed between the cultivars. Galling index was highest (5.5) in cv. KP93739.26 and lowest (1.9) in cv. Nyayo. All cultivars supported nematode reproduction with the highest (5.0) egg mass index being recorded in cultivars KP93739.26, Kerr's Pink, Desiree CIP-800048, KP92633.26 and B53. No cultivar exhibited immunity. The relationship between infection by root-knot nematodes and severity of bacterial wilt in three potato cultivars with varying levels of resistance to bacterial wilt namely Asante CIP 381381.20 (susceptible), B53 (moderately susceptible), and Kenya Dhamana (resistant), was investigated in a greenhouse experiment. Bacterial wilt was more severe in plants infected with both pathogens as compared to plants infected with Ralstonia solanacearum alone.

Jaoko W. Studies on the immunoepidemiology of bancroftian filariasis in East Africa.; 2002. Abstract

This study assessed the effect of transmission intensity on the patterns of
infection, disease and specific antibody response in bancroftian filariasis, by
comparing observed patterns of infection, disease and specific 19G1, 19G2, 19G3,
19G4and 19E profiles in two communities with high and low Wuchereria bancrofti
endemicity. The communities were Masaika in Tanga Region, Tanzania, which
was highly endemic for bancroftian filariasis, and Kingwede in Kwale District of
Kenya, which had low endemicity. Detailed analyses of specific antibody
responses were carried out in relation to infection and clinical status, age and
gender. An additional smaller part of the study investigated if seasonal variation in
transmission intensity influenced the stability of infection and specific antibody
responses.
The larger part of the study was cross-sectional and included all consenting
individuals aged 12 months and over. From each individual, demographic
information and medical history was obtained, followed by clinical examination and
blood sampling. Finger-prick samples were examined for microfilarie (mf) by
counting chamber method, and venous samples were analysed for circulating filarial
antigen (CFA) by the Trop Bio commercial kit for detecting W. bancrofti circulating
antigen in serum, and for filaria-specific antibodies (1gGl, 19G2, 19G3, 19G4 and
19E) using ELISA technique. Mean intensities of mf, CFA and filaria-specific
antibodies were all calculatedas geometric means.
Overall, mf and CFA prevalence and mean intensities were significantly higher
in Masaika than in Kingwede.In Masaika but not in Kingwede, mf and CFA mean
intensities were significantlyhigher in males than in females. This was mainly due
to gender differences in the 15-39 year age group. In both communities, infection
prevalence was higher, although not significantly, in children of infected parents
than in children of non-infectedparents.
Chronic filarial disease manifestations (hydrocele and elephantiasis) among
adults were more prevalent and presented earlier in Masaika than in Kingwede.
The proportion of individuals reporting having experienced acute
adenolymphangitis attacks during the one-year period preceding the survey was
also significantly higher in Masaika than in Kingwede, and was higher in adults
than in children, although this difference was statistically significant only in
Masaika.
Overall, prevalence and mean intensities of 19G1, 19G2, 19G4 and 19E were
significantly higher in Masaika than in Kingwede. The opposite pattern was seen
for 19G3.
Antibody profiles were analysed in relation to clinical and infection status of the
individuals in Masaika, but not in Kingwede where individuals with chronic disease
were too few for such analysis. The profiles were similar in asymptomatic and
chronic disease individuals. There was a highly significant association between
antibody profiles of all the measured antibodies and infection status. 19G1 and 19G2
were more associated with mf status than with CFA status and 19G3 and 19G4 were
more associated with CFA status than with mf status, while 19E was associated with

both mf and CFA status. These associations were not significantly influenced by
clinical status.
Due to few chronic filarial disease cases in Kingwede, inter-community antibody
profile comparison was restricted to asymptomatic individuals. In Masaika, IgG1
prevalence and intensity were significantly higher among mf negative individuals
than among mf positive individuals. The opposite pattern was seen in Kingwede
where both IgGI parameters were highest among the mf and CFA positive and
lowest among the mf and CFA negative. In Masaika, IgG3 profiles were associated
with both mf and CFA, while in Kingwede they were more associated with mf than
CFA. Furthermore, although in Masaika IgG2 and IgE were significantly associated
with mf status, in Kingwede their profiles were uniform in all infection groups. Only
IgG4 profiles were similar in the two communities, being highest among CFA
positive individuals and lowest among CFA negative individuals.
Age-specific antibody intensity patterns for IgGI, IgG4 and IgE were similar in
both communities. IgG1 and IgE decreased with age while IgG4 increased with age.
IgG2 and IgG3 profiles differed between the communities. IgG2 intensity decreased
with age in Masaika, but increased with age in Kingwede. IgG3 intensity remained
uniformlylow with age in Masaika but increased with age in Kingwede.
Despite clear gender differences in mf and CFA intensities in Masaika in the
female reproductive age group, there were no clear gender differences in antibody
intensities in this age group. IgG3 intensities were in general significantly higher
among mf or CFA positive females than among their male counterparts. The
oppositewas seen for IgG4 intensities.
Overall, mean IgG4/IgE ratio was significantly higher in Masaika than in
Kingwede. In Masaika, the ratios were higher among the chronic diseased than the
asymptomatic individuals in each infection group. These findings contrast what is
expected if this ratio indicates infection resistance level and if IgE mediates chronic
filarial disease pathogenesis, as has been suggested.
These results suggest that transmission intensity influences levels and patterns of
infection, disease and specific antibodies, and the association between infection
intensity and gender, and that antibody responses are more associated with infection
status than disease status. The study further suggests that the measured specific
antibodies are not the basis for the observed gender differences in infection
intensities in the female reproductive age group.
The last part of the study was longitudinal. A selected population of 37 CFA
positive males aged 20 to 40 years participated. Blood samples from each individual
were examined for mf, CFA and specific IgGI, IgG2, IgG3, IgG4 and IgE
antibodies at the beginning of the study, and at 6 and 12 months later. The time
points corresponded to high, low and high transmission seasons, respectively.
Transmission intensity during the study year was assessed entomologically by
catching, dissecting and examining mosquito vectors for infective larvae.

W. bancrofti transmission was found to be seasonal, with highest intensities
during the rainy season and lowest during the dry season in concert with mosquito
vectors abundance. Despite the marked seasonal variation in transmission potential,
no statistically significant variation was observed in the mf, CFA, measured filariaspecific
antibody levels or IgG4/IgE ratios, suggesting that seasonal transmission
may not result in seasonal fluctuations in the levels of infection, measured immune
responses or resistance to infection.

Three insecticides were tested in sprays in the field in Kenya in 1976 for the control of podboring insects, especially the noctuids Pardasena virgulana (Mab.) and Heliothis armigera (Hb.) and the agromyzid Melanagromyza obtusa (Mall.), on pigeon pea (Cajanus cajan). DDT was applied twice at a concentration of 25% diluted to 180 ml/10 litres water, 40% dimethoate was applied at 30 ml/18 litres, and 35% endosulfan at 102 ml/18 litres water; these quantities were applied to 450 m2. The percentage pod damage and (in brackets) percentage seed damage totalled 30.4 (18.3) for DDT, 24.7 (13.5) for dimethoate, and 32.4 (17.3) for endosulfan, as compared with 47.9 (24.4) for no treatment.

The electrochemical behaviour of ferricytochrome c, metmyoglobin and methemoglobin was studied using d.c., a.c. and differential pulse polarography, and controlled potential electrolysis. 1. The three hemoproteins yield d.c. polarographic steps, and peaks in differential pulse polarograms, the height of which is proportional to concentration. The charge transfer is influenced by strong adsorption. 2. The concentration dependence of the a.c. polarograms indicates structural changes in the adsorbed molecules. 3. The reduction products of controlled potential electrolysis of metmyoglobin and methemoglobin have absorption spectra identical with the native control samples. The affinity for oxygen and the cooperativity in hemoglobin are not affected by the reaction at the electrode. 4. The charge transfer proceeds via adsorbed, already reduced, molecules to freely diffusible proteins.

The world is today faced with the global pandemic of HIV/AIDS that has evolved rapidly since it was first described. The pandemic has been termed the greatest development challenge for sub Saharan Africa and is rapidly evolving in the Asian continent. The pandemic ha had a significantly negative impact on individual families through loss of loved ones, communities by increasing the burden of caring for the ill, and countries through reduced productivity.     As we look forward to the 21st century, the human population is reminded that even in an age where drugs to treat most ailments are available, human behaviour and individual aspirations are critical in the control of disease. Factors that affect human and social behaviour, such as poverty, discrimination and disenfranchisement have to be addressed on a global basis if the HIV/AIDS epidemic is to be controlled. The HIV/AIDS epidemic presents special challenges and new frontiers for public health interventions and research. HIV/AIDS has revealed the gaps in the understanding of how human behaviour is motivated and how it can be changed.     In this publication we present a review of some of the programs that are specifically targeting the youth with HIV/AIDS prevention activities in the countries of   This publication records the stories of men and women in Eastern Africa, who have tremendous commitment to the work they do even with minimal resources, because they have a vision for the youth of the African continent. It is a story of innovation, creativity, determination and partnership between adults and youth, communities and governments, countries, aid agencies and NGOSs.

Unilateral naris occlusion has long been the method of choice for effecting stimulus deprivation in studies of olfactory plasticity. A significant body of literature speaks to the myriad consequences of this manipulation on the ipsilateral olfactory pathway. Early experiments emphasized naris occlusion’s deleterious and age-critical effects. More recent studies have focused on life-long vulnerability, particularly on neurogenesis, and compensatory responses to deprivation. Despite the abundance of empirical data, a theoretical framework in which to understand the many sequelae of naris occlusion on olfaction has been elusive. This paper focuses on recent data, new theories, and underappreciated caveats related to the use of this technique in studies of olfactory plasticity.
