In recent years, there has been increasing interest in the use of electrophoretic deposition (EPD) in the production of oxidation and corrosion protective ceramic coatings. In this study, we address the kinetics and dynamics of submonolayer formation during EPD. The effect of constant current and constant voltage deposition conditions on deposition rate are analyzed and experimental data compared to theoretical models.

Two groups of 6 rats each received subcutaneous injections of 2.3 mg/kg or 5.0 mg/kg of quinuronium, respectively, on two consecutive days, while 5 rats injected with physiological saline served as controls. Clinical signs of muscular tremors, jumps, enlarged and hyperemic eyeballs, lacrimation, depression and anorexia were observed following administration of quinuronium. One rat receiving 5 mg/kg died before termination of the study. When killed 48 h after the first injection, the quinuronium-treated rats had a higher liver weight/body weight ratio compared to the controls. Quinuronium resulted in hepatic centrilobular fatty degeneration, but no depletion of hepatic glutathione (GSH). The present findings suggest that glutathione depletion does not seem to be involved in quinuronium hepatotoxicity.

Clematis brachiata Thunberg (Ranunculaceae) is used in Kenya for the management of headaches, malaria and other febrile illnesses, abdominal disorders, yaws and for skin disorders.  Old stems and leaves are chewed for the management of toothaches and sore throats. 
Extracts of the plant were subjected to tests for antimalarial, antibacterial and antifungal activity.  The toxicity of the extracts was assessed using the brine shrimp lethality bioassay.
 
The root extract gave the highest in vitro antimalarial activity against a mulitidrug resistant strain, Plasmodium falciparum VI/S (IC50=39.24 mg/ml). The stem and leaf extracts had insignificant antiplasmodial activity.  The leaf, stem and root extracts had bacterial or fungal growth even at very high concentrations of 10 mg/ml. The LD50 values of the stem and leaf methanol extracts against the brine shrimp larvae was 365.60 and 66.5 mg/ml respectively.
The in vitro anti malarial activity of the root extract in part supports the ethnobotanical use of the plant to manage malaria.

Nyongesa FW, Aduda BO, Nyaga WG. "Electrophoretic Deposition of TiO2 Thin Films for Photocatalytic Degradation of Organic Pollutants in Water." Tanzania Journal of Science. 2018;44(4):65-76. AbstractJournal Article Website

In this study, electrophoretic deposition (EPD) technique was used to deposit titanium dioxide (TiO 2) thin films on conducting glass substrates for application in photocatalytic degradation of organic pollutants in water. Phenol was used as a model pollutant. The EPD suspension related parameters and deposition conditions were first optimized for good quality film deposits. The suspension stability and deposition conditions that result in good adherence of TiO 2 particles to the substrate with homogeneous film coatings are ethanol, a TiO 2 solid loading of 4 wt%, a 0.2 wt% iodine concentration in the solvent and a deposition voltage of 20 V in a time of 3.5 minutes. The photocatalytic activity of TiO 2 thin films decreased exponentially with the ultraviolet light (UV) illumination time and it was also dependent on film thickness, and sintering temperature of the TiO 2 thin films. Highest rate of photocatalytic activity was observed at an optimal film thickness of 95±2 µm sintered at 300 C. The implications of these results are discussed for design of inexpensive wastewater purification systems for light industries as well for semi urban small communities

Cases of osteogenic sarcoma were studied as reported in the Kenya Cancer Registry covering a period of 15 years between January 1976 and December 1990. There were 271 cases with 113 (41.5%) coming from the Kikuyu community. The male to female ratio was 1.3 to 1 and the median age was 17 years. The tribal bias suggests either a genetic aetiology or a common environmental factor.

Nyumba TO. Are elephants flagships or battleships? : understanding impacts of human-elephant conflict on human wellbeing in Trans Mara District, Kenya. England: University of Cambridge; 2018. Abstract

This thesis examines the impacts of human-elephant conflict on human wellbeing and the implications for elephant conservation and management in Trans Mara District, Kenya. The District comprises communal lands bordering the world-famous Masai Mara National Reserve in southwestern Kenya. Trans Mara supports a range of land use types and provides refuge to one of Kenya’s large elephant population comprised of over 3,000 transient and 500 resident animals. This study used interdisciplinary methods to gain insights into the nature and consequences of conflict on the wellbeing of communities living with elephants. In particular, I used a combination of existing wellbeing indices and a set of indicators developed through consultations with local communities in TM to measure impacts of HEC on specific wellbeing domains. The results show that elephants still use the communal lands in Trans Mara but are increasingly restricted to the riverine forest remnants in central Trans Mara. However, there was no evidence of a further decline in the elephant range. Instead, this study points to a shift in elephant range against a background of increasing human settlement, land sub-division and agricultural expansion. The wellbeing of Trans Mara residents comprised eight indicators. Human-elephant conflict negatively affected peoples’ wellbeing, but the impacts were limited to certain dimensions. Elephants affected school-going children within elephant range. Attitudes towards elephants and its conservation in TM were influenced by the location of human residence relative to elephant refuge, diversity of income sources, and age and gender. Finally, conflict mitigation in Trans Mara is still elusive and challenging, but opportunities exist to develop simple and dynamic mitigation tools. The findings of this study have important implications for the future of elephant conservation in the face of competing human needs, both in Trans Mara District and elsewhere in Africa.

"Assessing the ecological impacts of transportation infrastructure development: A reconnaissance study of the Standard Gauge Railway in Kenya." PLOS ONE. 2021;16(1):e0246248-. AbstractWebsite

Transportation infrastructure, such as railways, roads and power lines, contribute to national and regional economic, social and cultural growth and integration. Kenya, with support from the Chinese government, is currently constructing a standard gauge railway (SGR) to support the country’s Vision 2030 development agenda. Although the actual land area affected by the SGR covers only a small proportion along the SGR corridor, a significant proportion of the area supports a wide range of ecologically fragile and important ecosystems in the country, with potential wider impacts. This study used a qualitative content analysis approach to gain an understanding and perceptions of stakeholders on the potential ecological impacts of the interactions between the SGR and the traversed ecological systems in Kenya. Three dominant themes emerged: 1) ecosystem degradation; 2) ecosystem fragmentation; and 3) ecosystem destruction. Ecosystem degradation was the most commonly cited impact at while ecosystem destruction was of the least concern and largely restricted to the physical SGR construction whereas the degradation and fragmentation have a much wider footprint. The construction and operation of the SGR degraded, fragmented and destroyed key ecosystems in the country including water towers, protected areas, community conservancies and wildlife dispersal areas. Therefore, we recommend that project proponents develop sustainable and ecologically sensitive measures to mitigate the key ecosystem impacts.

"Neurocognitive correlates of the use of combined Antiretroviral Therapy among HIV-infected adults attending care and treatment center at Muhimbili National Hospital, Dar es Salaam, Tanzania: An analytical crosssectional study." Tanzania Medical Journal. 2016. AbstractWebsite

The discovery of the highly active antiretroviral therapy has improved the life span of people living with HIV/AIDS (PLWHA) to almost that of the general population. This, however, has been coupled with increased incidences of HIVassociated dementia, especially mild cognitive impairment. Combined antiretroviral therapy (cART) has been observed to improve neurocognitive functions but the ART regimen that is best suited for improvement of neurocognitive functions is still largely unknown. This study was aimed at determining how neurocognitive deficits in patients on cART were related to ART regimen.

"The performance of International HIV dementia Scale (IHDS) versus Mini Mental Status Examition Scale (MMSE) in assessment of HIV-associated Neurocognitive Disorders (HAND) among HIV-Infected Tanzanian adults: a Case-Control Study.". 2016. AbstractWebsite

vailability of HAART has improved the outcome of HIV-associated neurocognitive disorders (HAND) though the prevalence is still high. Routine screening for HAND may offer room for early detection and prompt management that may improve overall outcome.

Objective

To compare the performance of International HIV dementia scale (IHDS) and Mini Mental Status Examination (MMSE) Scale in assessing HIV-associated neurocognitive disorders.

Methods

This was a case- control study involving 351 HIV-cases and 150 HIV-negative controls. International HIV dementia scale and Mini Mental Status Examination scale were used to screen for neurocognitive deficits.

Results

For cases, 91(25.9%) were males and 260(74.1%) were females while for 150 controls, 38(25.3%) were males and 112 (74.7%) were females. Under IHDS score 240(68.4%) of cases had HAND compared to 10(2.8%) when MMSE was used. The mean scores under MMSE for cases was 29±1.7 compared to 29.3± 1.2 for controls (p = 1.00). The mean IHDS scores for cases was 9.35 ± 1.89 compared to 10.35±0.89 (p < 0.0001) for controls.

Conclusion

Our findings suggests that IHDS has better sensitivity in detecting cases of HAND and perform better in identifying HIV/AIDS cases that requires further cognitive evaluation on comprehensive neuropsychological batteries.

This study genetically characterized five populations of the African catfish (Clarius gariepinus) in Kenya. Samples were obtained from five sites in the country–Athi River hatchery, Kisii Fingerling Production Centre (FPC), Jewlett hatchery, Sagana Hatchery Station and Lake Baringo. DNA was extracted from tissue samples, followed by amplification and sequencing of the dloop region. Haplotype diversities, phylogenetic structure and variation at the dloop region of mitochondrial DNA were assessed. Mitochondrial DNA analyses indicated that the sampled species showed genetic diversity between its populations. The genetic results were congruent indicating the differences in diversities and haplotype similarities of catfish samples from different sites. The Sagana, Kisii FPC, Jewlett and Baringo population cluster overlapped indicating possibly shared source of brood stock. The Athi river population was in a different cluster and its distinctiveness is attributed to imported brood stock. Both Athi River hatchery and Lake Baringo populations were highly variable and has great potential for production.

Resistance to the antifolate sulfadoxine–pyrimethamine (SP), the current mass-treatment antimalarial drug, is associated with selection of point mutations in dihydrofolate reductase and dihydropteroate synthase. Among these mutations, the leucine 164 dihydrofolate reductase mutation (Leu-164) is associated with higher levels of SP resistance; this mutation is also associated with a decrease in the efficacy of chlorproguanil/dapsone, a newly developed antifolate antimalarial drug. Leu-164 has been detected in Southeast Asia and South America, regions where SP is no longer effective. Surprisingly, this mutation has not yet been detected in Africa, using the standard protocol based on PCR–RFLP, despite high SP resistance. In this paper, we discuss briefly the reasons why Leu-164 has not yet been selected in Africa and we propose a means that may slow down the selection of this mutation.

Plasmodium falciparum parasites resistant to the combination sulfadoxine-pyrimethamine are spreading in Africa, particularly in East Africa. This is a matter of concern because there are no other affordable drugs available. This article provides the evidence indicating that sulfadoxine-pyrimethamine resistance can be reversed in vitro and discusses how this information might be exploited to extend the therapeutic lifetime of sulfadoxine-pyrimethamine in vivo

In this paper we introduce the notions of an A-self-adjoint, an A-skewadjoint linear operator, where A is a self-adjoint and invertible operator and related classes of operators, which generalize some known classes of operators. We investigate some properties of these operators and show that these operators share some properties with some known classes of operators. We prove some results on some equivalence of these operators and investigate conditions under which these operators are self-adjoint, unitary, skew-adjoint, normal, hyponormal, quasinormal or binormal. We also attempt to locate the spectra of such operators

Nzioka OM, Kaijage E, Ochieng DE. "Financial Integration, Macroeconomic Volatility And Economic Growth In The East African Community." European Scientific Journal. 2017;13(19):317-331. Abstract

This study aimed at determining the moderating effect of macroeconomic
volatility on the relationship between financial integration and
economic growth in the EAC.
The study adopted a positivistic research philosophy and casual research
design.. Generalized-two stage least squares instrumental variable regression
model (G2SLSIV) was then conducted to test the hypothesis. The findings of
the study showed that, macro-economic volatility does not have a significant
moderating effect on the relationship between financial integration and
economic growth. Therefore, the study recommends that, the governments of
respective member states work on a monetary policy that aims to attain a
single digit level of inflation rate (low inflation targeting), in the spirit of
macro-economic convergence. The study culminates with acknowledging the
limitations encountered and provides suggestions for further research.

Purpose-This study was carried out with an aim to analyze the effect of
diversification strategies on capital structure of non-financial firms listed at NSE. The
study focused specifically on analyzing the effect of product (related and unrelated)
and geographical diversification on capital structure.
Methodology-An exploratory study design was used to collect data, with the
population of the study being 64 firms listed in NSE. Out of the 64 firms, 41 non-
financial firms were selected as the sample of the study. Data was collected from
secondary sources, NSE and capital market authority. Data collected was analyzed
through STATA by the use of panel data regression analysis.
Findings- Related product diversification had a coefficient of 21.5(p-value=0.007)
indicating that it has a significant relationship with capital structure. The study results
show that debt is the most preferred form of financing in related product
diversification strategies. Unrelated product diversification had a coefficient of 22.7(p
value =0.006) indicating that it has a significant relationship with capital structure.The
findings of this study show that debt is the most preferred form of financing in
unrelated product diversification strategies. Geographical diversification had a
coefficient of 0.178 (p-value=0.799) indicating that it doesn’t have a significant
relationship with capital structure.Geographical diversification boosts the worth of
shareholders by taking advantage of specific assets and by accelerating functioning

This study looks at the perspectives of adolescent boys aged 15–19 attending schools in rural, eastern Kenya on the dual risks of unwanted pregnancy, STDs and HIV, based on qualitative data from eight focus group discussions with 90 boys. Despite a high knowledge of sexual risks, fear of HIV and awareness of the protective value of condoms, the young men exhibit high risk behaviour. They feel the need to conform to social prescriptions of male prowess, early sexual experience, and having more than one partner, yet their feelings about this behaviour are ambiguous and contradictory. They consider getting girls pregnant and having had a treatable STD as marks of masculinity, blame girls for not protecting themselves (and girls' parents), and want to boast about their sexual conquests to their peers. Yet they feel embarrassed and reticent about discussing sexual issues with adults, and are unwilling to get condoms from places where anonymity is not assured as they know their sexual activity is not sanctioned. There is a clear need for educational programmes that confront male sexual norms, address issues of gender power relations, promote communication skills, informed choice and sexual responsibility among boys as well as girls, and provide a consistent supply of good quality condoms free or at affordable prices.

Over the last six years there has been a tremendous development of infrastructure projects in virtually all corners of Kenya. This has taken the form of Road Improvement Project, Water and sewerage improvement project and the Electricity Transmission Improvement Project as envisioned in the Kenya Vision 2030. The purpose of this paper is to investigate the principles of compulsory land acquisition and way leaves in the three sectors in Kenya by looking at the current legislative framework governing the entire process of acquisition. In considering the process, the paper explores the various provisions of the relevant act which governs the particular utility envisaged for improvement project component in the Kenya Vision 2030. A critical evaluation of the procedures adopted is outlined in each case and the general public apprehensions towards such acquisitions. The second part of the paper focuses on suggestions on the choice of valuation methodology in making claims for compensation for land for various infrastructure projects in Kenya. This is borne out of the fact that there appear to be very little standardization in the methods adopted by the various bodies. The paper cites several cases under the Electricity Transmission Improvement Project where a large proportion of way leaves are dealt with at local level, with little consistency. Coupled to this is the public concern that electricity lines have potentially serious health effects that continue to attract research and media interest. The paper concludes with a description of the various cases on how to improve compensation paid to those affected by compulsory acquisition in cases of land and way leaves.

We conducted a prospective audit of 101 children with severe malnutrition aged 6 to 59 months admitted to Kenyatta National Hospital, Kenya's largest tertiary level health facility, from February-April 2008. A structured tool was prepared to capture data to allow assessment of implementation of the WHO guidelines steps 1-8. Overall, 58% of children had marasmus and 47% of children were younger than one year old. Common co-morbidities at admission were diarrhoea (70.3%) and pneumonia (51.4%). The highest degree of implementation was observed for Step 5, treatment of potentially severe infections (90%, (95% CI 85.1-96.9)). Only 55% of the patients had F75 prescribed although this starter formula was available in this hospital. There was a delay in initiating feeds with a median time of 14.7 hours from the time of admission. There was modest implementation of Step 2, ensuring warmth (46.5%, 36.8-56.2), Step 3, treat dehydration (54.9%, 43.3-66.5) and Step 4, correct electrolyte imbalance, (45.5%, 35.6-55.8%). There was least implementation of Step 8, transition to catch-up feeding (23.8%, 13.6-34.0). We conclude that quality of care for children admitted with severe malnutrition at KNH is inadequate and often does not follow the WHO guidelines. Improving care will require a holistic and not simply medical approach.
