Pd-F:SnO2 thin films have been prepared by spray pyrolysis technique using an alcoholic precursor solution consisting of stannic chloride (SnCl4.5H20), ammonium fluoride (NH4F) and palladium chloride (PdCl2). Optimization on the deposition parameters has been done in order to obtain high quality thin films. The effect of varying the fluorine content on the optical properties of Pd-F:SnO2 thin films were studied. Data for transmittance and reflectance in the wavelength range from 300nm – 2500nm was measured using the solid spec 3700DUV spectrophotometer. The calculated optical band gap of the as prepared thin films has been found to range from 3.8eV to 4.11eV. Fluorine incorporation for Pd-F:SnO2 has been found to have a narrowing effect on the band gap, but at its higher concentration the band gap has been seen to increase. The band gap narrowing is due to the incorporation of F- ions in the crystal lattice therefore giving rise to donor levels in the SnO2 band gap which is an essential characteristic for the gas sensor applications. Both annealing and passivation have been found to have very insignificant change in optical band gap of Pd-F:SnO2.

Objective: To determine the pattern of breast disease at Kenyatta National Hospital (KNH) Study design:    Retrospective descriptive study Study setting:    Kenyatta National Hospital, a University teaching and National Referral Hospital Patients: Records of 1172 patients were reviewed. Results: An average 469 new patients per year or 11 new patients per clinic visit were seen at the clinic over a two and a half year period. Females predominated (98.9%) in this series. The mean age was 34.71 years (range 1 to 96 years). The average age at menarche was 14.49 years and the mean duration of symptoms was 6.86 months. Only 2.6% of 843 patients had a positive family history of breast disease. Fibroadenoma was the commonest diagnosis made (33.2%) followed by ductal carcinoma (19.7%). Gynaecomastia was the most common lesion seen in males. Two thirds of patients presenting with tumors had masses measuring more than 5cm.  Overall five conditions (fibroadenoma, ductal carcinoma, breast abscesses, fibrocystic disease and mastalgia) accounted for over 85% of all breast ailments. Surgery formed the main stay of care in over 80% of patients. Conclusions: The pattern of breast diseases at KNH closely mirrors those reported in other studies in the region and beyond. This study indicates that a large proportion of patients presenting with breast disease are treated initially by surgery. It may be wise to consider other alternative forms of therapy where appropriate. The Annals of African Surgery: 2008 June; Vol 2, pg 97-101.

Puparia of Glossina morsitans centralis (Machado), G.fuscipes fuscipes (Newstead) and G.brevipalpis (Newstead) were incubated at 25 +/- 1 degrees C, 28 +/- 1:25 +/- 1 degrees C, day:night or 29 +/- 1 degrees C throughout the puparial period, and maintained at 70-80% relative humidity. Puparial mortality was higher at 29 than at 25 degrees C (optimum temperature) in all three species, particularly in G.f.fuscipes and G.brevipalpis. Adults of G.m.centralis from puparia incubated at 29 degrees C, and those of this subspecies, G.f.fuscipes and G.brevipalpis from puparia incubated at 28:25 degrees C, day:night or 25 degrees C throughout, were infected as tenerals (27 h old) by feeding them at the same time on goats infected with Trypanosoma congolense (Broden) IL 1180 after the parasites were detected in the wet blood film. Infection rates on day 25 post-infected feed were higher in G.m.centralis from puparia incubated at 29 degrees C and in adults of the three different tsetse species from puparia incubated at 28:25 degrees C, day:night, than in those from puparia incubated at 25 degrees C. However, in G.f.fuscipes the labral and hypopharyngeal infection rates were not significantly different from those of the tsetse produced by puparia kept at 25 degrees C.

Nyongesa FW, Aduda BO. "The Effect of Quartz and Mullite Pahses on Strength of Triaxial Porcelain." East African Journal of Physical Sciences. 2004;1(5):11-24. Abstract

The effect of quartz and mullite crystalline phases on the strength of triaxial porcelain in the system
quartz-feldspar-kaolin composed of 20%wt silica and feldspar/kaolin ratio of 5:8 has been
investigated. It was found that secondary mullite crystals enhanced both the compressive strength and
elastic properties of porcelain by the interlocking mechanism. Excess glass formation decreased the
fracture strength of porcelain as a result of the combined effect of circumferential cracks around
quartz grains and the microcracks within the quartz grains. The circumferencial cracks due to the
difference in the thermal expansion coefficient mismatch between the glassy and the quartz phases,
whereas the microcracks were due to a- to b- quartz phase inversions.

JOAB PROFBWAYOJOB. "The effect of rapid HIV-1 testing on uptake of perinatal HIV-1 interventions: a randomized clinical trial. Malonza IM, Richardson BA, Kreiss JK, Bwayo JJ, Stewart GC. AIDS. 2003 Jan 3;17(1):113-8.". In: AIDS. 2003 Jan 3;17(1):113-8. Asian Economic and Social Society; 2003. Abstract
Background. The host immune response against mucosally-acquired pathogens may be influenced by the mucosal immune milieu during acquisition. Since Neisseria gonorrhoeae can impair dendritic cell and T cell immune function, we hypothesized that co-infection during HIV acquisition would impair subsequent systemic T-cell responses.   Methods. Monthly screening for sexually transmitted infections (STIs) was performed in high risk, HIV seronegative Kenyan female sex workers as part of an HIV prevention trial. Early HIV-specific CD8+ T cell responses and subsequent HIV viral load set point were assayed in participants acquiring HIV, and were correlated with the presence of prior genital infections during HIV acquisition.   Results. Thirty-five participants acquired HIV during follow up, and 16/35 (46%) had a classical STI at the time of acquisition. N. gonorrhoeae co-infection was present during HIV acquisition in 6/35 (17%), and was associated with an increased breadth and magnitude of systemic HIV-specific CD8+ T-cell responses, using both interferon- (IFNg) and MIP-1 beta (MIP1b) as an output. No other genital infections were associated with differences in HIV-specific CD8+ T cell response, and neither N. gonorrhoeae nor other genital infections were associated with differences in HIV plasma viral load at set point.   Conclusion. Unexpectedly, genital N. gonorrhoeae infection during heterosexual HIV acquisition was associated with substantially enhanced HIV-specific CD8+ T-cell responses, although not with differences in HIV viral load set point. This may have implications for the development of mucosal HIV vaccines and adjuvants.
Ndiritu A, RUGENDO CAROLINE, Chandi J, Keiyoro P, Mbwesa J. "The effect of Reading skills on academic performance of Distance learners: A case of the University of Nairobi Distance Learners."; 2013. Abstract

Vision 2030 reveals the magnitude of wastage in the transition from secondary to University Education. It notes that secondary school enrolment has risen from 112,229 in the 2006/2007 academic year to 118,239 in 2007/2008 academic year; the passage to university is at 3 percent. To raise the Gross Enrolment Ratio (GER) of university students from the present 3 per cent to the projected 15 per cent, the government must continue increasing the number of students joining higher education from 130,000 (2008) to 450,000 (2015). This can be done by expanding the capacities of existing universities through establishment of new courses in Distance Education. The university of Nairobi school of continuing and distance education runs a course in distance education. It has been observed that many students fail to score a total of 40% in a given course and they re-sit the failed units. The failure rate goes up to 63% with 27% out of 38% cases, which is a very high failure rate. High failure rate and the ever increasing time taken to graduate is a chronic problem in Distance learning. One of the reasons why there could be poor performance is lack of quality time in reading. It is therefore worth knowing how efficiency in distance learning can be enhanced. To find out the effect of reading skills on academic performance a study was carried out. A total number of 650 students were selected using stratified random sampling technique. This sample was taken from 4,500 University of Nairobi students who were registered for B.Ed degree in different levels of study in the school of continuing and distance Education. A mixed mode method approach was used in data collection. Correlational research design was employed in data analysis. Pearson correlations were used to establish if there was a relationship between reading skills and academic performance. The analysis indicated a strong relationship between reading skills and academic [r= 0.569]. The value of r2 =0.324, indicated that reading skills accounts for about 32.4% of the variation in average performance.

Robinson Musembi, Aduda B, Mwabora J, Rusu M, Fostiropoulos K, Lux-Steiner M. "Effect of Recombination on Series Resistance in eta Solar Cell Modified with In(OH)xSy Buffer Layer." International Journal of Energy Engineering. 2013;3(3):183-189. AbstractWebsite

Transport mechanism studies in TiO2/In(OH)xSy/Pb(OH)xSy/PEDOT:PSS eta solar cell have been carried out. The characterizations have been performed both in the dark and under varying illumination intensity for temperature range 200 K – 320 K. Calculations from ideality factor have shown that the recombination process of the eta solar cell in the dark to be tunneling enhanced, while under illumination it is thermally activated and takes place through exponentially distributed energy recombination levels. The temperature has been found to influence series resistance of the solar cell. Series resistance has been found to be high at low temperature and low at higher temperature, thus we can conclude that the recombination is thermally activated.

Magoha GAO. "The effect of rectal examination on serum acid phosphatase levels in benign and malignant prostatic disease." Postgraduate Medical Journal . 1982;(58):763-766. Abstract

Serum acid phosphatase was measured in patients with enlarged benign and malignant prostate before and after rectal examination. Amongst the patients with benign glands, rectal examination did not produce any significant false elevation of the enzyme. Rectal examination, however, caused a rise in the enzyme level in a few untreated cancer patients and in cancer patients who has become refractory to hormonal therapy. This rise would help rather than mislead in the diagnosis of malignant prostate and also in the identifying treated patients who had become refractory to treatment. Thus, when serum acid phosphatase is properly determined, elevated levels should always arouse suspicion of malignant prostate or other lesions associated with high enzyme level even is such determination was preceded by rectal examination. There appears to be no merit in the teaching that the determination of serum acid phosphatase should be delayed after rectal examination.

Kinyanjui E, Ochieng DE. "Effect of Remittances from Diaspora on Financial Sector Deepening in the East African Community ." African development finance journal. 2017;1(1):82-10. Abstract

Abstract
Purpose – This paper investigated the effect of diaspora remittances on financial sector deepening in the East African Community. Personal diaspora remittances were used as a measure of remittances from diaspora. The three proxies for financial deepening that were employed in the study were domestic credit as a ratio of GDP, total credit provided by the financial sector as a percentage of GDP and degree of monetization, M2 as a percentage of GDP.
Methodology – The study adopted an explanatory research design. It employed panel data analysis - fixed effects method, to model the linear regression equation. The population of the study was the five East African Community member countries and covered a 20-year period (1997 to 2016). The data for this study was obtained from the World Bank statistics website.
Findings – This study established that there exists a positive relationship between remittances from diaspora and financial sector deepening in the EAC but this relationship is not significant. The three models analyzed in this study, show that a 0.31, 0.08 and 0.28 change respectively, in remittances in the respective models, leads to a unit change in the level of financial sector deepening in the EAC.
Implications – The results of this study show that an increase in the level of remittances leads to increased financial deepening in the EAC economies. There is therefore need for the government in liaison with the private sector, to provide a conducive environment for development of financially innovative products that ease and reduce the cost of sending remittances as this will foster further financial deepening, which has the positive effect of financial inclusion, access to credit and economic growth.
Value – This study recommended the fostering of activities that are geared towards the ease of sending remittances and cost reduction of sending the remittances through employment of new financial technologies. Further studies have also been recommended to increase the frontiers of the study especially on developed countries in order to gain more conclusive understanding and generalizability of the remittances-financial sector deepening nexus.

Mustafa KN;, Chemining'wa GN;, Nyabundi JO. "Effect of rhizobium inoculation of beans on growth and yield of maize and beans under different Intercropping patterns."; 2005. Abstract

The same row and this also out-yielded sole Rhizobium inoculation of beans (Phaseolus vulgaris L.) and intercropping patterns of maize and beans were evaluated for two seasons in a field study. Plant population of each crop in all planting patterns was 53,333 plants ha-1. Beans were either uninoculated or inoculated with Rhizobium. Planting patterns consisted of maize and beans intercropped in the same hill, maize and beans intercropped as. alternating plants in the same row, maize and beans intercropped in alternate rows, sole maize and sole beans. Increasing intimacy between the intercrop species and inoculation significantly increased biomass and leaf area indices of both maize and beans, and also the number of nodules per bean plant. Inoculation significantly increased yield of maize in all intercropping treatments. In the inoculated treatments, intercropping maize and beans in the same hill had significantly higher maize grain yield than intercropping in alternate hills in the same row and this, in turn, out-yielded sole maize cropping and intercropping in alternate rows whose yields were not significantly different. When beans were inoculated, similar results were obtained but in the second season no difference was observed between intercropping in the same hill and intercropping in alternate hills in the same row. Sole maize was also significantly superior to maize intercropped with beans in alternate rows. Beans intercropped with maize in the same hill out-yielded beans intercropped with maize in alternate hills in the same row and this also out-yielded sole beans. Beans intercropped with maize in alternate rows had the lowest yield. These results demonstrate the superiority of intercropping maize and beans in close proximity and Rhizobium inoculation both of which promoted nodulation by the bean plants. There is need to establish why beans intercropped with maize in the same hill out¬yielded sole beans.

Muthomi JW;, Otieno PE;, Chemining’wa GN;, Nderitu JH. Effect Of Root Rot Pathogens And Fungicide Seed Treatment On Nodulation In Food Grain Legumes.; 2013. Abstract

Greenhouse experiments were conducted over 2 cropping cycles to investigate the effect of fungicide seed treatment and fungal root rot pathogens on nodulation and dry matter accumulation of selected food legumes. The legumes were common bean (Phaseolus vulgaris L.var GLP 2), green gram (Vigna radiata L., variety M66) and lablab (Lablab purpureus L.). Treatments included, inoculation of legumes with pathogen alone (Fusarium oxysporum f.sp. phaseoli or Macrophomina phaseolina or Sclerotinia sclerotiorum or Rhizoctonia solani), or with appropriate rhizobia alone or application of fungicide (copper oxychloride) or their combinations. Results of the study indicated that fungicide seed treatment reduced disease incidence on Sclerotinia and Rhizoctonia inoculated plants. However, fungicide treatment significantly (p=0.05) depressed nodulation of the legumes but its effect on nodulation was significantly suppressed when applied together with rhizobia on infected seeds. Fungicide application significantly reduced seedlings mortality (pre-emergence damping off) and number of nodules per plant but had no effect on dry matter accumulation. Combination of fungicide and rhizobia inoculation improved nodulation as well as reducing disease incidence. It is therefore concluded that this combination yields better results if the aim is to reduce root rot incidence while improving nodulation concurrently.

SOLOMON DRDERESE. "Effect of Rotenoids from the seeds of Millettia dura on Larvae of Aedes aegypti.". In: Chemical Sciences Journal Vol. 2012: CSJ-56. Elsevier; 2003. Abstract

A crude chloroform extract of seeds of Millettia dura Dunn (Leguminosae) showed high activity (LC50 = 3.5 microg ml(-1) at 24 h) against second-instar larvae of the mosquito, Aedes aegypti L (Diptera: Culicidae). The rotenoids, deguelin and tephrosin, isolated from the seeds of this plant also showed potent activities, with LC50 values of 1.6 and 1.4 microg ml(-1) at 24 h, respectively. The related rotenoids millettone and millettosin were inactive at 20 microg ml(-1). Saturation at the B/C ring junction and the presence of methoxy groups at C-2 and/or C-3 in deguelin and tephrosin appear to be important for the observed larvicidal activity.

MBUYA TO, ODUORI MF, Rading GO, WEKESA MS. "Effect of runner design on mechanical properties of permanent mould aluminium castings.". 2006. AbstractWebsite

A comparison of the influence of different runner designs on the mechanical properties of aluminium castings has shown that filtered rectangular runners (FRRs) yield aluminium castings with higher and more reliable mechanical properties than the conventional unfiltered rectangular runners. Unfiltered vortex flow runners have also been shown to improve the reliability of the modulus of rupture of cast aluminium alloys over unfiltered rectangular runners. In the present paper, experimental results of a comparative study on the effect of the unfiltered vortex flow and FRR designs on the tensile strength of permanent mould aluminium castings are reported. The results show that an FRR yields castings with higher and more reliable tensile strengths than the unfiltered vortex flow runner. Castings poured into a mould with an FRR had strengths between 269 and 291 MPa and a Weibull modulus of 50·2 while castings poured into the vortex flow runner had strengths between 255 and 280 MPa and a Weibull modulus of 40·3.

Essential thrombocythaemia was diagnosed in a series of 18 patients on the basis of platelet counts greater than 1,000 X 10(9)/1. Radionuclide studies have been carried out to distinguish thrombocythaemia as a primary disease from polycythaemia vera, myelofibrosis and chronic granulocytic leukaemia presenting with high platelet counts. These have included blood volume and spleen function, and radio-iron (52Fe) has been used to demonstrate the presence of extramedullary (splenic) erythropoiesis. The value of these investigations in distinguishing between the various myeloproliferative disorders associated with thrombocythaemia is illustrated.

Purpose – This paper sought to establish the effect of selected macro-economic variables
on exchange rates in Kenya. The selected macro-economic variables for this study were
interest rates, inflation rates and trade flows.
Methodology – The study was modeled as a descriptive survey. A data collection sheet
was used to collect secondary data from the published bulletin and other publications by
Central Bank of Kenya and Kenya National Bureau of Statistics for a period of ten years
between 2006 and 2015. The data was examined using descriptive, correlation and
regression analyses.
Findings - Results of the study showed that interest rate had a positive correlation
coefficient of 0.446 with exchange rate, Inflation rate and exchange rate had a correlation
coefficient of negative 0.395 while the Level of aggregation of trade flows had a
correlation coefficient of positive 0.829 to the exchange rate. The value of R square was
0.745, a discovery that 74.5 percent of the deviations in exchange rates in Kenya
occurred due to changes in interest rate, inflation rate and trade flows at 95 percent
confidence level. The significance value obtained was less than p=0.05 implying that the
model was statistically significant in predicting how the macro economic variables of
interest rate, inflation rate and trade flows affect exchange rates in Kenya.
Implications - The Kenyan shilling has been depreciating in value over the years
implying a weakening of its purchasing power in the international markets. Policy makers
should come up with policies that will contribute to reversing this trend. Managing the
prevailing levels of inflation, interest rates and trade flows will be key as they have been
found to significantly affect exchange rates.
Value - The study will act as a guide to variou

Isolated mouse interstitial cells were incubated with different concentrations of khat (Catha edulis) extract (0.06 mg/ml, 0.6 mg/ml. 6 mg/ml. 30 mg/ml and 60 mg/ml) and cell viability as well as testosterone concentration measured at 30 min intervals over a 3 h incubation period. High concentrations of khat extract (30 mg/ml and 60 mg/ml) significantly inhibited testosterone production while low concentrations (0.06 mg/ml. 0.6 mg/ml and 6 mg/ml) significantly stimulated (P < 0.05) testosterone production by mouse interstitial cells. Similarly, at concentrations of 30 mg/ml and 60 mg/ml, there was a significant decrease in interstitial cell viability, whereas at 0.06 mg/ml, 0.6 mg/ml and 6 mg/ml there was no significant decrease. There was only a weak correlation (r= 0.39) between testosterone production and viable interstitial cells. We postulate that khat extract at high concentrations may cause reproductive function impairment in the user but at low concentrations. may enhance testosterone production with accompanying effects on reproductive functions in male mice. @2006 Publishedby Elsevier Ireland Ltd.

The desire of any service organization is to deliver quality service that meets their customer expectations so as to remain profitable and in business. The service market has now become more competitive than ever before and meeting customer needs is a necessity. Petroleum distributing firms in Kenya are at a great task of perfecting their service delivery systems to ensure that their customers get quality product at the right time, right quantity and above all safely. Well managed service quality practices have the potential of transforming the operational performance of an organization. The objectives of the study were to determine the extent of adoption of service quality management practices by petroleum distributing firms in Kenya, the challenges they face in the implementation of these practices and the effect of these practices on the firms’ operational performance. The study was carried out through a descriptive survey of 32 petroleum distributing firms in Kenya. Drop and pick later questionnaires were used to collect primary data. The collected data was analyzed using the Statistical Package for Social Sciences (SPSS) and descriptive statistics like mean and standard deviation used to summarize the findings. The regression analysis technique was used to establish the relationship between the dependent and independent variables. The research findings were presented in tables. The findings indicated that petroleum distributing firms adopted various service quality management practices to a large extent. The findings also indicated that the firms were faced by various challenges in their endeavour to implement the service quality management practices. Further, the findings indicated that there existed generally a positive relationship between service quality management practices and operational performance. The main conclusion was that the adoption of service quality management practices by petroleum distributing firms was inevitable since it improved the operational performance of these firms. The researcher recommends that policy makers should ensure organizations embrace service quality management practices for improved productivity and better returns from their investments. The researcher concludes by suggesting that similar research to be carried out in other sectors of the economy other than petroleum industry.

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

Development literature has recently promoted the use of producer organizations in linking farmers to better-paying
commodity markets. However, empirical studies find mixed performance of such organizations. This study examines the producer
organizations’ internal factors that may explain the differences in the performance of producer organizations. The study specifically
analyzes the role of social capital, within a producer organization, on the performance of such organization using quantitative
techniques. The level of commercialization is used as proxy of organization’s performance. The study finds that social capital
positively affects the performance of producer organizations. These findings imply that development strategies that target the
promotion commercialization of smallholder agriculture through producer organizations should pay attention to the internal factors
within such organizations.
Key words: Smallholder farmers, agricultural commercialization, social capital, performance of farmer organizations, Kenya.

The study aimed at identifying soil fertility practices that promoted nematode destroying fungi in the soil and the treatments comprised of Mavuno fertilizer, Triple super- phosphate and calcium ammonium nitrate (TSP+CAN), cow manure and a control where no amendments were applied. This experiment was replicated in ten farms for three planting seasons. There were significant difference (P= 1.705 x 10-06) in occurrence of the nematode destroying fungi between soil fertility treatments. The highest mean occurrence of nematode destroying fungi was 1.6 which was recorded in soils amended with cow manure and the least was in soils from the control plots. A mean of 0.78 was recorded in soils from both TSP+CAN and Mavuno fertilizers. Plots amended with cow manure gave the highest diversity of nematodes followed by the control, then TSP+CAN and least in Mavuno with shannon indices of 0.34, 0.15, 0.13 and 0.11 respectively. Sixty percent of all the isolated nematode destroying fungi genera were from plots treated with cow manure and only twenty percent were from plots amended with the inorganic fertilizer

Studies of fertilizer use in sub-Saharan Africa have been dominated by analyses of economic and market factors having to do with infrastructure, institutions, and incentives that prevent or foster increased fertilizer demand, largely ignoring how soil fertility status conditions farmer demand for fertilizer. We apply a switching regression model to data from 260 farm households in western Kenya in order to allow for the possibility of discontinuities in fertilizer demand based on a soil carbon content (SCC) threshold. We find that the usual factors reflecting liquidity and quasi-fixed inputs are important on high-SCC plots but not on those with poorer soils. External inputs become less effective on soils with low SCC, hence the discernible shift in behaviors across soil quality regimes. For many farmers, improved fertilizer market conditions alone may be insufficient to stimulate increased fertilizer use without complementary improvements in the biophysical conditions that affect conditional factor demand.

The inhibitory effect of molybdenum ions on growth of yeasts at pH 5.5 was found to be decreased by aldoses in the following order: D-talose greater than L-mannose greater than L-ribose greater than D-lyxose greater than L-galactose greater than L-arabinose greater than L-glucose greater than L-xylose. Increased concentrations of molybdenum brought about morphological changes of yeast cells. Cells grown under these conditions were smaller, had thicker walls and formed clusters.

Essential thrombocythaemia was diagnosed in a series of 18 patients on the basis of platelet counts greater than 1,000 X 10(9)/1. Radionuclide studies have been carried out to distinguish thrombocythaemia as a primary disease from polycythaemia vera, myelofibrosis and chronic granulocytic leukaemia presenting with high platelet counts. These have included blood volume and spleen function, and radio-iron (52Fe) has been used to demonstrate the presence of extramedullary (splenic) erythropoiesis. The value of these investigations in distinguishing between the various myeloproliferative disorders associated with thrombocythaemia is illustrated.

It is distributed globally with high prevalence in sub-Saharan African, southern Asia, China and Japan. Diagnosis is experimental and in many cases inaccurate due to unreliability of markers. 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. We investigated the effect of polysaccharide rich Pleurotus pulmonarius fruit body extracts on progression of chemically induced hepatocellular carcinoma in CBA mice.

Karuri EG;, Ojijo NKO. "Effect of storage conditions on sweet potato roots."; 1995. Abstract

Four sun-cured lots of sweet potato (cv KSP20) roots were stored under different conditions in the laboratory. One lot was stored in environmental cabinets operated at five temperature levels of 5, 10, 15, 20, arid 29°C.The other two lots were stored in open wooden boxes, one filled with soil and the other saw-dust. A control sample was exposed to the ambient air in the laboratory. Objective physical and chemical indices were used to monitor the quality changes in the stored roots. Although the storage time and temperature were important in influeincing the quality of the roots, temperatures of 10°C or lower and also higher than 15°C were unsuitable for storage. At those temperatures sprouting, rotting, pithiness, shrivelling or a combination of the physiological factors became more important in quality deteriaration. Subsequently, prolonged storage was possible only at 15 and 20°C and also in saw-dust and soil cover. Roots stored in soil or saw-dust were as wholesome as those at 15°C, save for the sprouting which depleted the dry matter content, and had superior appearance. Exponential decay could predict Vitamin C and B-carotene loss. Reducing sugar developed in all samples but was highest in the ambient air storage. Using the back-extrusion test, it was shown that there were no significant differences between boiled roots after 4 weeks of storage under all conditions.

Fatigue crack growth tests were performed on compact tension specimens (CTS) made in two thicknesses 12 and 24 mm. Tests were conducted at two frequencies of 0·25 and 30 Hz, applying a stress ratio R varying from – 0·7 to 0·7. The results were analysed using the linear elastic fracture mechanics approach. They showed that the increase in both positive and negative R caused increased fatigue crack growth rates. Also an empirical effective stress intensity factor range, ΔKeff, was found more appropriate to correlate the fatigue crack growth data than the ΔK factor frequently used in crack growth studies. The loading frequency had only a little influence on crack growth rates at low R. However, at high R, growth rates were significantly higher at lower frequencies. It is suggested that this frequency influence may be associated with environmental effects, due to the embrittlement caused by hydrogen from the moist air, while the crack was fully open.

The purpose of this study was to evaluate the effect of supplementing Moringa oleifera leaf meal
(MOLM) at different levels in broiler chicken. Broiler starter and finisher diets were formulated using raw
materials obtained from local feed manufacturers. MOLM was first analyzed for crude protein and then added
to diets at levels of 0% (T1), 7.5% (T2), 7.5% (T3) (without Methionine and lysine), 15 (T4) and 30% (T5). Two
hundred (200) day old broiler chicks were randomly allocated into the 5 treatment groups with 4 replicates
of 10 birds each and the diets introduced. The feed intake, feed conversion ratio (FCR), weight gain, lipid
profile, abdominal fat pad and feed digestibility were determined. The MOLM crude protein level was 23.33%.
The weight gain was significantly different between the various diets with the highest weight gain being in
T1 at 1464 and the lowest in diet T5 at 500. MOLM supplementation at levels above 7.5% decreased the feed
intake and dry matter digestibility. The abdominal fat pad (AFP) was significantly higher in T1 compared to
T2, T4 and T5. The males had a significantly high levels of High density lipids (HDL) than females in T2, T3
and T4 (p<0.05). The yellow colour of the carcass increased with the increased levels of MOLM. It was
concluded that Moringa oleifera leaf meal (MOLM) was well tolerated and can only be included in the feed
to levels of up to 7.5% as higher levels affected weight gain, feed intake and digestibility. Further studies on
the yellowing of the carcass, its quality and acceptability by consumers is needed.
Key words: Moringa oleifera leaf meal, broiler chicken, feed intake, weight gain, abdominal fat pad, feed
digestibility

Kenya experienced extraordinarily heavy rainfall between May 1997 and February 1988 due to the El Nino weather phenomenon. This period of about 10 Months of heavy rainfall caused widespread landslides and floods in various parts of the country. An enormous number of landslides occurred in Central, Western and to the Coast Provinces. This triggered a nation-wide crusade to plant trees in an effort to counter future landslide phenomenon. However, little quantitative research has been conducted to assess the impact of plant roots on soil strength. As a result, planting of trees tend to be more empirical without consideration of the structural measures for reinforcing soil that combine the ecological benefits of vegetation. This paper describes the contribution of plant roots of various species to soil shear strength. Soil samples with roots of various plant species were tested in a large modified direct shear apparatus in a laboratory set-up. Shear stress results of rooted soils were compared with results of soil without roots of similar soil types. The contribution of roots to soil strength was estimated by comparing the difference between the maximum shear stress of the shear-displacement curves obtained for soils with and without roots for the different species tested. Results suggested that the rooted soils contributed more to soil strength than rootless soils. However there was varying degree of shear strength contribution for different root species suggesting that for each species, contribution of shear strength was governed by root density. The results suggested that a composite soil-root system consumes energy while resisting shear displacement. This feature could be included in stability analysis of vegetated hillslopes in terms of energy associated with shearing in a soil-root system.

Sloan JW, Martin WR, Wala E.J Pharmacol Exp Ther. 1993 Jun;265(3):1152-62.". In: J Pharmacol Exp Ther. 1993 Jun;265(3):1152-62. Kisipan, M.L.; 1993. Abstract
The ability of different chronic doses of diazepam to produce dependence was studied in groups of six dogs who received diazepam p.o. (0.05625, 0.225, 0.5625, 4.5, 9 or 36 mg/kg/day) every 8 hr. After 5 to 6 weeks of stabilization, the intensity of precipitated abstinence was measured by benzodiazepine-precipitated abstinence scores (BPAS) after the p.o. administration of graded doses of the benzodiazepine antagonist, flumazenil (0.66, 2, 6, 18, 36 and 72 mg/kg or a placebo). A modified Latin square design was used. Dogs receiving the two lowest stabilization doses of diazepam showed only liminal signs of precipitated abstinence even with 72 mg/kg of flumazenil. The intensity of the precipitated abstinence syndrome increased with the stabilization dose of diazepam. There was also a dose-related increase in BPAS for increasing doses of flumazenil for all doses of diazepam except the 9-mg/kg/day dose. Not only were quantitative differences observed in precipitated abstinence signs for different levels of diazepam dependence, but the pattern of abstinence signs differed also. Dogs dependent on high doses of diazepam were more sensitive to flumazenil than those dependent on lower doses. Furthermore, seizure activity was seen only in dogs dependent on 9 and 36 mg/kg/day of diazepam. BPAS increased linearly with plasma and brain total and free levels of the sum of diazepam and its metabolites (oxazepam and nordiazepam), but not with free plasma and brain levels of diazepam.

This study sought to determine the effect of the Youth Enterprise Development Fund (YEDF) on youth enterprises. The study location was in Siaya County, Kenya and stratified random sampling was used to select 28 financiers of YEDF and 202,897 youths in the County. The sample size constituted 128 respondents; 28 in the first stratum and 100 in the second stratum. The data was collected using survey questionnaires and analyzed through multiple linear regression analysis. The study concluded that the YEDF has not had a significant effect on youth enterprises. The study recommends an increase in the number of financial intermediaries (FIs) in partnership with the fund and an active involvement of all the stakeholders in mobilization of the youth on group formation and YEDF activities.

Vision 2030 reveals the magnitude of wastage in the transition from secondary to University Education. It notes that secondary school enrolment has risen from 112,229 in the 2006/2007 academic year to 118,239 in 2007/2008 academic year; the passage to university is at 3 percent. To raise the Gross Enrolment Ratio (GER) of university students from the present 3 per cent to the projected 15 per cent, the government must continue increasing the number of students joining higher education from 130,000 (2008) to 450,000 (2015). This can be done by expanding the capacities of existing universities through establishment of new courses in Distance Education. The University of Nairobi’s School of Continuing and Distance Education runs a course in distance education. It has been observed that many students fail to score a total of 40% in a given course and they re-sit the failed units. The failure rate goes up to 63% with 27% out of 38% cases, which is a very high failure rate. High failure rate and the ever increasing time taken to graduate is a chronic problem in Distance learning. One of the reasons why there could be poor performance is lack of quality time in reading. It is therefore worth knowing how efficiency in distance learning can be enhanced. To find out the effect of time management of academic performance a study was carried out. A total number of 650 students were selected using stratified random sampling technique. This sample was taken from 4,500 University of Nairobi students who were registered for B.Ed degree in different levels of study in the school of continuing and distance Education. A mixed mode method approach was used in data collection. Correlational research design was employed in data analysis. Pearson correlations were used to establish if there was a relationship between time management and academic performance. The analysis indicated a strong relationship between time management and academic [r= 0.569]. The value of r2 =0.324, indicated that time management accounts for about 32.4% of the variation in average performance.

Background. The host immune response against mucosally-acquired pathogens may be influenced by the mucosal immune milieu during acquisition. Since Neisseria gonorrhoeae can impair dendritic cell and T cell immune function, we hypothesized that co-infection during HIV acquisition would impair subsequent systemic T-cell responses.   Methods. Monthly screening for sexually transmitted infections (STIs) was performed in high risk, HIV seronegative Kenyan female sex workers as part of an HIV prevention trial. Early HIV-specific CD8+ T cell responses and subsequent HIV viral load set point were assayed in participants acquiring HIV, and were correlated with the presence of prior genital infections during HIV acquisition.   Results. Thirty-five participants acquired HIV during follow up, and 16/35 (46%) had a classical STI at the time of acquisition. N. gonorrhoeae co-infection was present during HIV acquisition in 6/35 (17%), and was associated with an increased breadth and magnitude of systemic HIV-specific CD8+ T-cell responses, using both interferon- (IFNg) and MIP-1 beta (MIP1b) as an output. No other genital infections were associated with differences in HIV-specific CD8+ T cell response, and neither N. gonorrhoeae nor other genital infections were associated with differences in HIV plasma viral load at set point.   Conclusion. Unexpectedly, genital N. gonorrhoeae infection during heterosexual HIV acquisition was associated with substantially enhanced HIV-specific CD8+ T-cell responses, although not with differences in HIV viral load set point. This may have implications for the development of mucosal HIV vaccines and adjuvants.

"Effect of Trichoderma harzianum and arbuscular mycorrhizal fungi on growth in tomato (Lycopersicum esculentum Mill) seedlings, napier (Pennisetum purpureum L) and tea (Camellia sinensis L) cuttings." Tropical and Subtropical Agroecosystems. 2009;(11):423-429. Abstract

A green-house study was conducted to investigate the ability of an isolate of Trichoderma harzianum (P52) and arbuscular mycorrhizal fungi (AMF) in enhancing growth in tomato seedlings, tea and napier grass cuttings. The effect of these bio-inoculants on growth was compared with the influence of Diammonium phosphate (DAP) fertilizer and the interactions of these three factors (P52, AMF and DAP). The plants were grown in plastic pots filled with sterilized soils. A completely randomized design was used and growth measurements taken on height shoot and root dry weights. It was observed that isolate P52 and DAP fertilizer individually enhanced growth in tomatoes, tea and napier while AMF only enhanced growth in tomatoes. Combinations of P52 and DAP; P52, AMF and DAP enhanced growth significantly (P<0.05). Trichoderma harzianum and AMF showed potential for use as biofertilizers to reduce on chemical inputs in the perspective of sustainable agriculture and conservation of natural resources.

Maichomo MW;, Gathuma JM;, Ndung'u JM;, Matere CN. "Effect of trypanosomosis and tick borne diseases on productivity of Orma / Zebu cattle in an (ASAL) area of south western Kenya."; 2008. Abstract

Trypanosomosis and tick-borne diseases (TBD’s) have a profound impact on the livelihoods of agro-pastoralists in the ASAL areas of Kenya whose transhumance nature exposes livestock to tsetse-infested areas and also new ground may be sources of parasites. Both diseases are endemic and cause suboptimal production, which is enhanced in presence of endoparasites and nutritional stress. Trypanosomosis infected animals have pronounced immunosuppression and easily succumb to TBD’s even in presence of endemic stability and perhaps trypanotolerant animals will show minimal loss in production. A trial was conducted in trypanosomosis endemic foci to assess productivity of three hundred Orma zebu (OZ) (trypanotolerant Orma boran x Maasai zebu) and Sahiwal zebu (SZ) (susceptible Sahiwal x Maasai zebu) crosses, which were monitored monthly from birth to 18 months for prevalence of trypanosomosis and TBDs, and body weight changes. Diagnosis was based on parasitology and serology. Growth rate and disease prevalence were used as outcome measures of productivity. Factors associated with these outcome variables were assessed using multiple regression [Proc Reg, SAS version 9.1, SAS Institute Inc., Cary, NC, USA] and logistic regression [Proc Logistic] fitted at 95% confidence level. Daily weight gain for the O/Z and S/Z were 0.209 g/d and 0.212 g/d respectively and comparable. Prevalence of trypanosomosis, TBD and EPG counts were 1.9% and 2.5%; 59% and 62%; 48 and 42 in the O/Z and S/Z respectively. Factors significantly associated with disease distribution were season and age of calves. Enhanced trypanotolerance in O/Z crosses can be utilized for effective reclamation of tsetseinfested lands.

The effect of unilateral naris occlusion on the cellular dynamics of developing olfactory epithelium was investigated in postnatal rats. Nares of rat pups, at 1, 5, and 10 d postnatally, were cauterized; after a 30 d survival period, the olfactory mucosa was examined histologically, and quantitative estimates were made of total number of receptor neurons (together with basal cells), supporting cells, and epithelial thickness. In each group, there were significant differences between occluded and patent sides in total numbers of neurons and in epithelial thickness but no difference in number of supporting cells. The differences were greater in the animals that had been occluded for 1–30 d than in the 5–35 or 10–40 d groups, suggesting that the earlier postnatal days are more sensitive to the effects of occlusion. We evaluated the number of mature olfactory neurons by staining immunohistochemically with an antibody against olfactory marker protein. There were no differences in the number of mature receptor neurons between the occluded and non-occluded sides, indicating the effect of naris occlusion was on the neurons in the immature and/or the “almost mature” population. Using 3H-thymidine autoradiography, we determined that there was a 40% reduction in the rate of neurogenesis in the animals occluded 1–30 d after birth. Further, the rate of cell proliferation in nasal respiratory epithelium declined by approximately the same amount.(ABSTRACT TRUNCATED AT 250 WORDS)

The study was set to investigate the effect of universalistic perspective of human resource strategic orientation on performance of large private manufacturing firms in Kenya. The target population was all large private manufacturing firms in Kenya that were registered members of Kenya Association of Manufacturers. The research adopted descriptive research design which utilized both descriptive and inferential statistics for effective generation of the required output. Using probability sampling, a sample of 108 firms was chosen. Data was collected using questionnaires developed by other researchers and that these were modified by the researcher. The respondents
were human resource managers, finance managers, corporate planning managers or any other senior manager. The Statistical Package for the Social Sciences (SPSS) version seventeen (17) was used to analyze the data. The results of this study showed that there was high positive correlation between universalistic human resource strategic orientation and firm performance. These results to a great extent show that all forms of universalistic human resource strategic orientation enhance performance of manufacturing firms and most particularly those registered with the Kenya Association of Manufacturers (KAM). These findings can also be generalized
to cover all other manufacturing firms in the country. As of the direction for further study, the researcher recommends that future research in universalistic human resource strategic orientation focus on public manufacturing firms and for the sake of knowledge, consider the use of longitudinal research design as opposed to the survey research designed which was central to this study. Further still, researchers should consider moderating or intervening variables. The main contribution of this paper lies in highlighting the fact that, proper configuration of universalistic human resource strategic orientation in manufacturing firms, will enable them enhance performance.

According to UN demographic projections, the world population aged 60 years and above is increasing rapidly. It is estimated that by the year 2025, there will be about 1.2 billion people above the age of 60 years worldwide. The older population in Africa currently estimated to be slightly over 42 million is projected to reach 205 million by 2050. Many of the elderly enter old age after a life of deprivation with limited access to resources. Objectives: The purpose of this study was to determine the nutritional and oral health status of elderly persons as a part of a wider study carried out in Nairobi, Kenya. Methods: Data were collected from 289 persons aged 45 years and above using a semi-structured questionnaire. Oral health status was assessed by dental examination, while nutritional status was assessed using Body Mass Index (BMI) and Mid Upper Arm Circumference (MUAC). Results: The study established that many of the elderly persons suffered from dental problems, especially periodontitis, dental caries, tooth mobility and missing teeth. The level of malnutrition using the MUAC was 18.8% while by BMI it was 11.4%. 46.4% had normal nutritional status while some of them (40.9%) were overweight, with more females (48.0%) than males (25.9%) being overweight. Conclusions: Undernutrition, obesity and dental problems are issues of concern among the elderly in Nairobi.

Stover placement (surface mulch, incorporated or a mixture of mulch and incorporation) was compared with stover removal in the presence and absence of 50kg N fertilizer/ha in trials over two successive seasons in continuous maize cropping systems in two regions in Kenya. Stover applied at 4 tonnes DM/ha was found to have highly variable effects on maize growth and yield according to site., method of stover placement, N application and season. Relative to controls without stover, stover incorporation reduced yield by 39% in the first season, followed by yield increases of 15% in the second season. In the first season there was little or no response to N in the presence of stover. Low N uptake and N use efficiency suggested N immobilization in the incorporation treatment. Yield responses and large N uptake in the following season suggested mineralization of N immobilized in the previous season. Surface mulching at the Kabete site increased grain yields in the first season by 39% and 6% compared to stover removal without and with fertilizer, resp. In the second season, surface mulching markedly reduced yields possibly due to a combination of reduced phytotoxicity and N immobilization. At the Katumani site, stover amendments increased yields compared to removal in both seasons with incorporation results being superior to surface mulch. At this site, in both seasons, application of N reduced the effect of stover mulching and incorporation. You must log in to CAB Direct in order to view search results. If you have forgotten your log
