This study determined the prey base for four main carnivores found in Samburu Community group ranches and grazing area, Lion (Panthera leo), Leopard (Panthera pardus), Wild dog (Lycaon pictus) and Hyaena (Crocuta crocuta, and Hyaena hyaena). A total of 96 scat samples including, 8 from Lion, 16 Leopards', 2 Wild dogs', and 70 Hyaenas' were collected, identified and microscopically analyzed for prey hair characterisation. At least 50 different hairs from every scat sample were mounted on slides and microscopically characterized using details from reference hairs. Hairs from 18 depredated species both domestic and wild ungulates were recovered from the scat samples. Predated species were identified, as either domestic (Cow, Sheep, Goat, Donkey, and Camel) or wild ungulate prey (Grant's gazelle, plain zebra, Grevy's Zebra, Impala, Waterbuck, Dikdik, Eland, lesser Kudu, greater Kudu, Baboon, rock Hyraxes, Elephant and Oryx). The carnivores showed a relatively high kill of wild ungulate prey compared to domestic prey. Camel was the most preferred cow and donkey respectively. Grevy's zebra contributed highest to the lion's diet while the Plain zebra was most preferred by the leopard. Both the hyaena and Wild dog had a preference for the waterbuck. The Hyaena had the highest domestic depredation, while all the other big cats depredated more on wild ungulates.

Key words: Scat, group ranch, domestic, wild ungulate, prey, depredation.

Kemoli AM. "Dilemma of managing multi-surface dental caries in the primary dentition using the atraumatic restorative treatment: renaissance or dimming hope." East Afr Med J . In Press. Abstract

Background: Alot of research work has been carried out to determine the effectiveness of using atraumatic restorative treatment (ART) in the management of dental caries, but there are still unresolved issues surrounding the use of the technique particularly in very large carious lesions.
Objective: To determine the current survival rates of multi-surface ARTrestorations placed in the primary dentition and any consequences to the restored tooth after premature loss of the restoration.
Study selection: Using a set of specific key words, a Pubmed/Medline search was carried out to retrieve all publications on ARTrestorations placed in primary teeth in the period January 2000 to December 2011. Only publications whose studies had multi-surface ARTrestorations as an item of study were retrieved and relevant data extracted.
Data synthesis: Twelve studies contained in 12 publications fulfilled the selection criteria and were included in the study. The selected publications were analysed by the author to establish the study follow-up period and the survival rate of the multi-surface ARTrestorations for the different follow-up periods. Further information was adduced on any other effects of restoration on the tooth after premature loss of the restoration.
Results: The search findings indicated that the survival rate for most of the multi-surface restorations were generally very low. Further, there were indications that even after the premature loss of the ARTrestorations, most of the affected teeth survived for the period of the study with a number of them having shown no signs of secondary caries or associated dental abscessees.
Conclusion: While the survival rates of multi-surface ARTrestorations in the studies documenetd in the review were low, the ART restorations appeared to provide some beneficial effects to the retention-longevity of the restored tooth even after their premature loss.

Transrenal urine cell-free DNA (cfDNA) is a promising tuberculosis (TB) biomarker, but is challenging to detect because of the short length (<100 bp) and low concentration of TB-specific fragments. We aimed to improve the diagnostic sensitivity of TB urine cfDNA by increasing recovery of short fragments during sample preparation. We developed a highly sensitive sequence-specific purification method that uses hybridization probes immobilized on magnetic beads to capture short TB cfDNA (50 bp) with 91.8% average efficiency. Combined with short-target PCR, the assay limit of detection was ≤5 copies of cfDNA in 10 ml urine. In a clinical cohort study in South Africa, our urine cfDNA assay had 83.7% sensitivity (95% CI: 71.0 to 91.5%) and 100% specificity (95% CI: 86.2 to 100%) for diagnosis of active pulmonary TB when using sputum Xpert MTB/RIF as the reference standard. The detected cfDNA concentration was 0.14 to 2,804 copies/ml (median 14.6 copies/ml) and was inversely correlated with CD4 count and days to culture positivity. Sensitivity was nonsignificantly higher in HIV-positive (88.2%) compared to HIV-negative patients (73.3%), and was not dependent on CD4 count. Sensitivity remained high in sputum smear-negative (76.0%) and urine lipoarabinomannan (LAM)-negative (76.5%) patients. With improved sample preparation, urine cfDNA is a viable biomarker for TB diagnosis. Our assay has the highest reported accuracy of any TB urine cfDNA test to date and has the potential to enable rapid non-sputum-based TB diagnosis across key underserved patient populations.

BackgroundManagement and control of the COVID-19 pandemic caused by the severe acute respiratory syndrome coronavirus SARS-CoV-2 is critically dependent on quick and reliable identification of the virus in clinical specimens. Detection of viral RNA by a colorimetric reverse transcription loop-mediated isothermal amplification (RT-LAMP) is a simple, reliable and cost-effective assay, deployable in resource-limited settings (RLS). Our objective was to evaluate the intrinsic and extrinsic performances of RT-LAMP in RLS.
Methods
This is a multicenter prospective observational study of diagnostic accuracy, conducted from October 2020 to February 2021 in four African Countries: Cameroon, Ethiopia, Kenya and Nigeria; and in Italy. We enroled 1657 individuals who were either COVID-19 suspect cases, or asymptomatic and presented for screening. RNA extracted from pharyngeal swabs was tested in parallel by a colorimetric RT-LAMP and by a standard real time polymerase chain reaction (RT-PCR).
Findings
The sensitivity and specificity of index RT LAMP compared to standard RT-PCR on 1657 prospective specimens from infected individuals was determined. For a subset of 1292 specimens, which underwent exactly the same procedures in different countries, we obtained very high specificity (98%) and positive predictive value (PPV = 99%), while the sensitivity was 87%, with a negative predictive value NPV = 70%, Stratification of RT-PCR data showed superior sensitivity achieved with an RT-PCR cycle threshold (Ct) below 35 (97%), which decreased to 60% above 35.
Interpretation
In this field trial, RT-LAMP appears to be a reliable assay, comparable to RT-PCR, particularly with medium-high viral loads (Ct < 35). Hence, RT-LAMP can be deployed in RLS for timely management and prevention of COVID-19, without compromising the quality of output.

Demand for natural fibers is on the rise as awareness of environmental protection keeps abreast. Sisal fibers, for instance, are largely utilized not only in the manufacture of mats, ropes, carpets, and sacks but also in the reinforcement of polymer composites. With the increased demand for sisal fibers, there is a need to equally increase the exploitation of sisal by small-scale farmers. UNIDO, for instance, recommended that appropriate small-scale machines that are accessible to small-scale holders should be developed. This research examines the progress in the development of small-scale machines and designs a raspador for simultaneous extraction and brushing of sisal fibers. This is to ensure that there is value and income addition for the small-scale farmers in East Africa and perhaps the rest of the world.

This study mapped the role of ICT, digital platforms, the internet connectivity and skills of the personnel vis-à-vis implementation processes of SDGs in public organizations in Kenya. Findings show cross-cutting institutionalization and internalization deficits as a result of limited mastery of ICT skills and training of the personnel, insufficient ICT platforms, mainly, computers, poor internet connectivity and poor investment in digital platforms by the government institutions. An organizational culture that predisposes institutions to change resistance also constrained integration of SDG goals in public organizations. The article concludes by providing critical policy recommendations for addressing these problems.

Most corporate governance studies have focused on the composition and effectiveness of board members, little attention has barely focused on the interaction between the identity of significant shareholders and the decisions they influence in the firm. Corporate governance literature is currently based on empirical studies in developed countries, but the efficiency of developed and developing markets corporate governance mechanisms is disparagingly different. This paper presents an ideal moment for examining the complementary effect of dividend policy and ownership concentration by shareholders at Nairobi Securities Exchange in a developing securities exchange. Previous studies examining the interaction between corporate governance and firm value have emphasized the significance of institutional shareholder concentration and dividend policy decisions as corporate control mechanisms that influence value creation in a firm. This study is supported by dividend signaling and institutional shareholder monitoring hypothesis. The study used longitudinal data for the period (2008-2017) and the target population is sixty-six companies trading securities at NSE 2008-2017. Empirical results reveal, firms listed at Nairobi Securities Exchange have a high level of ownership concentration and dividend payment has a significant positive effect on the firm value which is in line with the signaling hypothesis, the mediating effect of ownership concentration was negated therefore did not support shareholder monitoring hypothesis. The findings of this study have significant policy implication to policymakers, regulators should not rely on market mechanism as protection to minority owners. Firms should be encouraged to regularly pay dividends if profitable and investors should understand the ownership structure of listed firms they invest in.

Abstract
Keloids are fibroproliferative disorders characterized by high recurrence rates, with few factors known to influence the same. We conducted a study to determine whether keloid histology influences recurrence. This was a prospective longitudinal study to determine whether histopathological parameters of keloid influence recurrence. Patients with keloids managed by surgical excision were followed up at Kenyatta National Hospital between August 2018 and July 2020. The excised keloids were processed for histology using hematoxylin,/eosin, Masson, and trichrome stains. The slides were analyzed for inflammatory cells, fibroblasts, and capillary density using the hot spot technique and correlated to keloid recurrence. Postoperative follow-up was for a minimum of 1 year. A total of 90 patients with 104 keloids were recruited in the study. Overall keloid recurrence rate was 28.6%. There was a correlation between the absolute count of more than 50 per High power field of lymphocytes, fibroblasts, and macrophages with recurrence of the disease. The sensitivity and specificity for the above parameters were lymphocytes 48% and 81%, macrophages 57% and 83%, mast cells 32% and 33%, and fibroblasts 41% and 91%, respectively. There was no correlation between mast cells and vascularity status with recurrence. Routine histology should, therefore, be performed to determine these parameters. Close monitoring and second-line therapy should be considered for patients with elevated macrophages and/or lymphocytes so as to reduce the risk of recurrence.

Taenia species of domestic dogs can cause cysticercosis and coenurosis in a wide range of intermediate hosts including humans. Most taeniids of dogs are globally distributed, but some wildlife-transmitted species can be specific for certain regions. Generally, little information exists on the species composition and frequency in most regions of the world, which impairs risk assessment and control strategies. This study determined the range of taeniid species in dogs in four widely spaced areas of Kenya by genetic identification of eggs in faeces collected from the environment. Individual taeniid eggs were characterised by nested polymerase chain reaction of NADH dehydrogenase subunit 1 and cytochrome C oxidase 1 genes, restriction fragment length polymorphism and partial sequencing. Overall 79/1621 (4.9%) faecal samples contained eggs of Taenia or Hydatigera (8.0% in Turkana, 4.8% in Isiolo, 3.8% in Maasai Mara and 1.3% in Meru). Taenia hydatigena and T. multiceps were the most frequent, found in 36 and 15 samples, respectively. Other eggs found in the faeces belonged to T. serialis (sensu lato), T. madoquae (the first record in domestic dogs), T. ovis, T. saginata and Hydatigera taeniaeformis. Polymorphism of nad1 sequences revealed 22 and 8 haplotypes of T. hydatigena and T. multiceps, respectively. The results show the involvement of dogs in both domestic and sylvatic transmission cycles. In addition to the species range, this study provides data on the intraspecific diversity of T. hydatigena and T. multiceps in Kenya, which will serve as baseline information for further studies into cysticercosis and coenurosis in livestock and humans in the region.

In this paper we analyze a Chemostat model with periodic nutrient input modelled using Fourier series and incorporate delays in nutrient conversion. We show that both periodicity and delays have complementing influence in the long term behaviour of the species. Numerical results show that periodicity has bigger influence on species density variations for delays below the Hopf Bifurcation point, while for delays above the Bifurcation point,the delay effect is more influential.

Background: Rheumatoid arthritis
is a systemic inflammatory disease that affects the synovial membrane,
resulting in the structural damage of cartilage, bone and ligaments. The
course of RA differs between patients, and its severity can range from selflimiting
disease to severe destruction and systemic complications. RA affects
patients physically, psychologically and socially. Patients experience pain,
joint swelling, stiffness, functional limitations and fatigue and overall poor
quality of life. In addition, they report anxiety and depressive symptoms
and concerns about increased physical limitations. Experiencing
psychological distress may inflate the subjective severity of patient-reported
symptoms such as pain and tenderness. Furthermore, patients experience a
loss of independence and restrictions in participation, i.e. a decrease in
socializing which may in turn propagate symptoms of depression. An accurate
description of the relationship between depression, disease severity and quality
of life is necessary for our setting. If an interaction exists, then there is a
group of vulnerable patients who could benefit from earlier identification
of depression and the impact their disease has on HRQoL and appropriate
management provided. Objective: To determine the prevalence
of depression and the relationship between depression, disease activity
and quality of life in ambulatory patients with rheumatoid arthritis at
the Kenyatta National Hospital.Design: A descriptive-cross sectional

The Kenyan microfinance sector faces many challenges such as high operation costs, increased credit risk, low visibility and poor understanding of emerging technology opportunities and risks among others. These problems are persistent due to low levels of innovation and limited uptake of digital financial technologies. This research aimed to identify the determinants that influence uptake of mobile fintech and propose an appropriate model for uptake of mobile fintech within the sector. A descriptive survey of all 30 Microfinance institutions registered with Association of Microfinance Institutions (AMFI) 2018 in Kenya was carried out. Data was collected using questionnaires from 120 respondents. Data was analyzed using descriptive and inferential statistics. Based on correlation model, this study established that technology factors (r=0.862, P<.05), environmental characteristics (r=0.387, P<.05) and organizational factors (r=0.256, P<.05) have a strong influence on the uptake of mobile fintech. Using regression model, technology factors (β=.563, P<.05), organizational factors (β=.281, P<.05) and environmental characteristics (β=.562, P<.05) all have positive and significant influence on uptake of mobile fintech. These factors include technology availability, perceived technology benefits, organization size, resources availability, and competition, regulatory and legal environment among others. Uptake of mobile fintech was found to reduce operation costs and improve business operations efficiency. Understanding of the factors derived in this study will help microfinance institutions, software developers and policy makers as they develop strategies directed at promoting successful implementation of mobile fintech.

AAS Open Research. 2020;3(51). AbstractWebsite

The increase in health research in sub-Saharan Africa (SSA) has led to a high demand for biostatisticians to develop study designs, contribute and apply statistical methods in data analyses. Initiatives exist to address the dearth in statistical capacity and lack of local biostatisticians in SSA health projects. The Sub-Saharan African Consortium for Advanced Biostatistics (SSACAB) led by African institutions was initiated to improve biostatistical capacity according to the needs identified by African institutions, through collaborative masters and doctoral training in biostatistics. SACCAB has created a critical mass of biostatisticians and a network of institutions over the last five years and has strengthened biostatistics resources and capacity for health research studies in SSA. SSACAB comprises 11 universities and four research institutions which are supported by four European universities. In 2015, only four universities …

PURPOSE:To describe the care seeking journey and causes of delay among patients with Microbial Keratitis in Uganda.
METHODS:A prospective cohort of patients presenting with microbial keratitis at the two main eye units in Southern Uganda (2016-2018). We collected information on demographics, home address, clinical history, and presentation pathway including, order of facilities where patients went to seek care, treatment advice, cost of care, and use of Traditional Eye Medicine. Presentation time was noted. We compared "direct" presenters versus "indirect" presenters and analysed predictors of delay.
RESULTS: About 313 patients were enrolled. All were self-referred. Only 19% of the patients presented directly to the eye hospital. Majority (52%) visited one facility before presenting, 19% visited two facilities, 9% visited three facilities, and 2% visited four facilities. The cost of care increased with increase in the number of facilities visited. People in a large household, further distance from the eye hospital and those who used Traditional Eye Medicine were less likely to come directly to the eye hospital. Visiting another facility prior to the eye hospital and use of Traditional Eye Medicine aOR 1.58 (95%CI 1.03-2.43), p = .038 were associated with delayed presentation to the eye hospital.
CONCLUSION: This study provided information on patient journeys to seek care. Delay was largely attributable to having visited another health facility: a referral mechanism for microbial keratitis was non-existent. There is need to explore how these health system gaps can be strengthened.

A recent study of HIV serodiscordant couples found that depot medroxyprogesterone acetate (DMPA) and oral contraceptive pills (OCPs) were associated with increased HIV risk in the presence, but not in the absence, of bacterial vaginosis. We assessed whether bacterial vaginosis is an effect modifier of the association between hormonal contraception and HIV seroconversion in female sex workers (FSWs) in Mombasa, Kenya.

Linalool oxide (LO) and hexanoic acid (HA) represent plant- and human-derived odorants, respectively, previously found as attractants for the dengue vector Aedes aegypti. Here, we investigated if a blend of both compounds can improve captures of this mosquito species in field trials in two dengue endemic sites, Kilifi and Busia Counties in Kenya. Ae. aegypti captures were significantly higher in Kilifi than Busia (χ = 170.63, P < 0.0001) and varied by treatments (χ = 151.19, P = 0.002). We found that CO-baited BG Sentinel traps combined with a blend of both odorants decreased Ae. aegypti captures about 2- to 4-fold compared to captures with the individual compounds (LO or HA) used as positive controls. This was the case for all blends of LO and HA, irrespective of the doses tested. Our findings indicate that combining plant- and human-derived odors may elicit a masking effect in trapping Ae. aegypti. These results partly corroborate previous findings for malaria mosquitoes which showed that combining lures from both host sources either decreases or increases trap catches depending on the dose. Further investigations in the usefulness of combining plant and animal odorants in mosquito trapping are therefore necessary.

The dataset presented here shows the microstructure and mechanical properties of secondary (recycled) cast aluminum-silicon (Al–Si) piston alloys processed through severe plastic deformation technique, known as high-pressure torsion (HPT). The HPT processing was undertaken for 1/4, 1/2, 1 and 10 turns of the lower anvil (rotating at constant speed of 1rpm) while the upper anvil maintained at a normal pressure of 3.0 GPa. The data on microstructural evolution obtained at the central region and edge of the circular (disk) HPT sample were obtained using optical and scanning electron microscopy and these data are presented here. The data on the analysis of the particle shape, sizes and distribution from the micrographs using ImageJ software are also presented. Data on mechanical properties characterized using Vickers microhardness measurement across the surface of HPT sample are also shown. Pictures depicting the microhardness measurement scheme, high-pressure torsion facility and sample nomenclature are presented.

"Device Simulation of Sb2S3 Solar Cells by SCAPS-1D Software." Africa Journal of Physical Sciences. 2019;3, 2019. Abstract

Antimony sulphide (Sb2S3) has drawn research interest due to its promising properties for photovoltaic applications. The progress in developing highly efficient Sb2S3 solar cells has stimulated this study to a great extent. In this paper, we present the results of a simulation of solar cell processing parameters on the performance of the solar cell through theoretical analysis and device simulation using SCAPS software. The results of this simulation show that the solar cell performance can be enhanced to a great extent by adjusting the thickness, doping concentration and defect density of both the TiO2 buffer layer and Sb2S3 absorber layer and also the electron affinity of the TiO2 buffer layer. Optimized parameters were found to be: doping concentration of (1.0 X 1017CM3 for TiO2 and 3.0 X 1016 CM3 for Sb2S3), defect density of the Sb2S3 absorber at (1.0 X 1015.....3) and the electron affinity of the buffer layer at (4.26 eV). The results obtained were as follows: Voc of 750 mV, Jsc of 15.23 mA/cm2, FF of 73.55% and efficiency of 8.41%. These results show that Sb2S3 is a potential earth-abundant compound that can yield highly efficient solar cells.

"Design, Implementation, and Operation of a Small Satellite Mission to Explore the Space Weather Effects in LEO." Aerospace. 2019;6. AbstractWebsite

Ten-Koh is a 23.5 kg, low-cost satellite developed to conduct space environment effects research in low-Earth orbit (LEO). Ten-Koh was developed primarily by students of the Kyushu Institute of Technology (Kyutech) and launched on 29 October 2018 on-board HII-A rocket F40, as a piggyback payload of JAXA’s Greenhouse gas Observing Satellite (GOSAT-2). The satellite carries a double Langmuir probe, CMOS-based particle detectors and a Liulin spectrometer as main payloads. This paper reviews the design of the mission, specifies the exact hardware used, and outlines the implementation and operation phases of the project. This work is intended as a reference that other aspiring satellite developers may use to increase their chances of success. Such a reference is expected to be particularly useful to other university teams, which will likely face the same challenges as the Ten-Koh team at Kyutech. Various on-orbit failures of the satellite are also discussed here in order to help avoid them in future small spacecraft. Applicability of small satellites to conduct space-weather research is also illustrated on the Ten-Koh example, which carried out simultaneous measurements with JAXA’s ARASE satellite.

"Developing open online learning resources: Lessons from a short course on the control of blindness from diabetic retinopathy.". In: College of Ophthalmologists in Eastern Central & Southern Africa (COECSA). Addis Ababa; 2018. Abstract

Background: A need identified during another study prompted the development of the open online course on control of blindness from diabetic retinopathy. In our technological age, potential for learning online can provide a unique opportunity to develop context-specific content for local relevance. We report on the lessons learnt in the development of this short online course for an international audience of diverse eye care practitioners.

Methods: We developed this online short course through a formal planning process facilitated by UNESCO. The participants included eye health educators, learning designers, and content experts. The course curriculum was informed by learning from an ongoing doctorate program, as well as by clinical, public health and educational experience.

Results: Lessons learnt include:
1. Identifying the need and content – Learning and research from a doctorate research program can inform content development.
2. Identifying the relevance – the content needs to be customized for the target audience and local context.
3. Developing the learning design – promoting digital teaching skills and co-creation of content are valuable entry points.
4. Accommodating appropriate peer review and mentorship may enhance learning and quality assurance.
5. Resource planning activities need to be documented as a learning point.
6. There are significant costs in course development, such as time spent in content development, and ongoing maintenance eg maintaining the online platform.
7. Sources of quality open access resources in eye care are limited.

Conclusion: Content development is a unique learning experience, and it is essential to develop and support context specific learning resources. Open educational practice supports a collaborative process that enhances relevance and quality of training. The online format emphasizes the importance of learning design requirements to bridge the transactional distance between the participant and the educator.

"Decay of HIV DNA in the Reservoir and the Impact of Short Treatment Interruption in Kenyan Infants." Open Forum Infect Dis. 2018;5(1):ofx268. Abstract

We compared change in HIV reservoir DNA following continued antiretroviral therapy (ART) vs short treatment interruption (TI) in early ART-treated Kenyan infants. While HIV DNA in the reservoir decayed with continued ART, HIV DNA levels were similar to pre-TI HIV DNA reservoir levels in most children after short TI.

"Discovery of a novel species, Theileria haneyi n. sp., infective to equids, highlights exceptional genomic diversity within the genus Theileria: implications for apicomplexan parasite surveillance." Int J Parasitol. 2018;48(9-10):679-690. Abstract

A novel apicomplexan parasite was serendipitously discovered in horses at the United States - Mexico border. Phylogenetic analysis based on 18S rDNA showed the erythrocyte-infective parasite to be related to, but distinct from, Theileria spp. in Africa, the most similar taxa being Theileria spp. from waterbuck and mountain zebra. The degree of sequence variability observed at the 18S rDNA locus also suggests the likely existence of additional cryptic species. Among described species, the genome of this novel equid Theileria parasite is most similar to that of Theileria equi, also a pathogen of horses. The estimated divergence time between the new Theileria sp. and T. equi, based on genomic sequence data, is greater than 33 million years. Average protein sequence divergence between them, at 23%, is greater than that of Theileria parva and Theileria annulata proteins, which is 18%. The latter two represent highly virulent Theileria spp. of domestic cattle, as well as of African and Asian wild buffalo, respectively, which differ markedly in pathology, host cell tropism, tick vector and geographical distribution. The extent of genome-wide sequence divergence, as well as significant morphological differences, relative to T. equi justify the classification of Theileria sp. as a new taxon. Despite the overall genomic divergence, the nine member equi merozoite antigen (EMA) superfamily, previously found as a multigene family only in T. equi, is also present in the novel parasite. Practically, significant sequence divergence in antigenic loci resulted in this undescribed Theileria sp. not being detectable using currently available diagnostic tests. Discovery of this novel species infective to equids highlights exceptional diversity within the genus Theileria, a finding with serious implications for apicomplexan parasite surveillance.

Beverage fraud involving counterfeiting of brand spirits is an increasing problem not only due to deception of the consumer but also because it poses health risks e.g. from possible methanol admixture. Suspicious spirit samples from Russia and Kenya were analysed using 1H nuclear magnetic resonance (NMR) spectroscopy in comparison to authentic products. Using linear regression analysis of spectral integral values, 4 counterfeited samples from Russia and 2 from Kenya were easily identifiable with R2 < 0.7. Sensory analysis using triangle test methodology confirmed significant taste differences between counterfeited and authentic samples but the assessors were unable to correctly identify the counterfeited product in the majority of cases. An important conclusion is that consumers cannot assumed to be self-responsible when consuming counterfeit alcohol because there is no general ability to organoleptically detect counterfeit alcohol.

Climate change and variability pose momentous severe threats to agricultural development and consequently to economic growth and increased poverty levels. In reference, this paper examines the determinants of household food security status and assesses the challenges of building resilience to climate variability and change posed by drought in Tharaka Nithi, Kenya. The study coverage is Tharaka North and Tharaka South sub-counties which are semiarid and cover an area of 1,569 square kilometers (km2) with a total population of 158,023 people; this is about 65% of Tharaka Nithi County (Kenya). The sub-counties have three main livelihood zones (LZs). These are marginal mixed farming at 52%, mixed farming at 38%, and rain-fed cropping at 10%.

The area is exposed to climate change, aggravated by minimal adaptive capacity. Climate variability and climate change threaten food production leading to about 20–30% of the population being in poor and borderline food consumption score. The year 2017 describes one of the cyclical drought situations with low productivity and depleted range land conditions exposing approximately 30,000 persons in need of humanitarian assistance. This study reflects on challenges of building resilience to climate variability and change posed by drought using a transdisciplinary approach. The problems of the household food security status were poor rainfall performance, high temperatures, low livestock prices, high food prices, poor crop production, poor pasture and browse quality, and inadequate water for both domestic and livestock use. The solutions to the above-listed issues lie in the increased advocacy, rainwater harvesting structures, marketing linkages, timely early warning knowledge management, and eco-based farming practices. The study also found that there was a significant relationship between the household level of education, family size, household income, and household head age with food security. Findings of this study will form a platform for policy makers.

Aluda AT, Amugune BK, Abuga KO, Kamau FN. "Development and Validation of a Gas Chromatographic Method for Determination of Menthol in Cold-Cough Syrups." PJK. 2018;23(3):90-93. Abstract

Background
Common cold is the most common infection of the upper respiratory tract and cold-cough syrups are often prescribed. Although menthol is one of the common constituents of these syrups, quality checks on cold-cough syrups normally target the major active pharmaceutical ingredients without regard to menthol content.

Objective
To develop and validate a gas chromatography method for determination of menthol in cold-cough syrups.

Methods
A simple, rapid, robust, accurate and reliable Gas Chromatography method was developed and validated for the determination of menthol in cold-cough syrups that may also contain ambroxol, chlorpheniramine, guaifenesin, bromhexine and salbutamol.

Results
Optimized chromatographic conditions were: A ZB-WAXplus 60m ×0.25mm; 0.25μm fused silica capillary column. Oven temperature program of 110 0C (2 min), ramp 10 0C/min to 190 0C (2 min). Injector port temperature maintained at 240 0C. Injection volume of 1.0 μl split in the ratio of 50:1. Carrier gas as nitrogen at 1.0mL/min which also serves as make up gas (30 mL/min) in the flame ionization detector (260 0C). Other detector gases were hydrogen (30 mL/ min) and industrial air (300 mL/ min) and the diluent for samples and standards was grade chloroform.
From recovery studies, 97.56 to 102.97 % recovery was reported. Repeatability studies had a coefficient of variation of 0.55 while intermediate precision was 0.32. The method was linear over a range of 0.042 to 0.169 mg/mL with a coefficient of determination (R2) 0.9986.
Of the 21 samples analyzed, only 10 samples (47.6 %) complied with assay specifications of 90.0 to 110.0 % label claim for finished products according to the United States Pharmacopeia 2016.

Conclusion and recommendation
A gas chromatographic method was developed and validated for the determination of menthol in cold-cough syrups in Kenya. This method can be used together with a validated high-performance liquid chromatography method to assay cold-cough syrups that may also contain ambroxol, bromhexine, chlorpheniramine maleate, guaifenesin and salbutamol.
This method can be useful in routine analysis such as pre-registration studies as well as post market surveillance to curb substandard and counterfeit cold-cough syrups.

The objective of the study was to determine the influence of ingratiation on employees’ career mobility. The study used a descriptive survey and a population study of 169 employees with a response rate of 122(72.2%). This is considered sufficient as recommended by experts (Mugenda and Mugenda, 2009). Primary data was collected using self-administered structured questionnaires. Descriptive statistics was used to analyse the data and the hypothesis formulated was analysed using linear regression analysis. The results confirmed the hypothesis thatingratiation influences career mobility (R2=.944, F=2011.237, P≤0.05). The correlation coefficient for the model was 0.971 which also confirms that there is a strong relationship between ingratiation and career mobility. The study recommends that objective means of performance appraisals be established and followed by superiors to ensure fair and credible ways of career mobility to its employees. The paper suggests if the same study can be replicated in other organizations using a longitudinal research design.
