Theileria parva infections in cattle causes huge economic losses in the affected African countries, directly impacting the livelihood of the poor small-holder farmers. The current immunization protocol using live sporozoites in eastern Africa, is among the control measures designed to limit T. parva infections in cattle. However, the ability of the immune protection induced by this immunization to protect against field parasites has been compromised by the diversity of the parasite involving the schizont antigen genes. Previous studies have reported on the antigenic diversity of T. parva parasites from southern and eastern Africa, however, similar reports on T. parva parasites particularly from cattle from southern Africa remains scanty, due to the self-limiting nature of Corridor disease. Thus, we evaluated the diversity of CD8+ T-cell regions of ten schizont antigen genes in T. parva parasites associated with Corridor disease and East Coast fever (ECF) from southern and eastern Africa respectively. Regions of schizont antigen (TpAg) genes containing the CD8+ T-cell epitopes (CTL determinants) were amplified from genomic DNA extracted from blood of T. parva positive samples, cloned and sequenced. The results revealed limited diversity between the two parasite groups from cattle from southern and eastern Africa, defying the widely accepted notion that antigen-encoding loci in cattle-derived parasites are conserved, while in buffalo-derived parasites, they are extensively variable. This suggests that only a sub-population of parasites is successfully transmitted from buffalo to cattle, resulting in the limited antigenic diversity in Corridor disease parasites. Tp4, Tp5, Tp7 and Tp8 showed limited to absence of diversity in both parasite groups, suggesting the need to further investigate their immunogenic properties for consideration as candidates for a subunit vaccine. Distinct and common variants of Tp2 were detected among the ECF parasites from eastern Africa indicating evidence of parasite mixing following immunization. This study provides additional information on the comparative diversity of TpAg genes in buffalo- and cattle-derived T. parva parasites from cattle from southern and eastern Africa.

Abstract
Background: There are still concerns over the safety of laparoscopic surgery in coronavirus disease 2019 (COVID-19) patients due to the potential risk of viral transmission through surgical smoke/laparoscopic pneumoperitoneum.

Methods: We performed a systematic review of currently available literature to determine the presence of severe acute respiratory syndrome coronavirus 2 (SARS-COV-2) in abdominal tissues or fluids and in surgical smoke.

Results: A total of 19 studies (15 case reports and 4 case series) comprising 29 COVID-19 patients were included. The viral RNA was positively identified in 11 patients (37.9%). The samples that tested positive include the peritoneal fluid, bile, ascitic fluid, peritoneal dialysate, duodenal wall, and appendix. Similar samples, together with the omentum and abdominal subcutaneous fat, tested negative in the other patients. Only one study investigated SARS-COV-2 RNA in surgical smoke generated during laparoscopy, reporting negative findings.

Conclusions: There are conflicting results regarding the presence of SARS-COV-2 in abdominal tissues and fluids. No currently available evidence supports the hypothesis that SARS-COV-2 can be aerosolized and transmitted through surgical smoke. Larger studies are urgently needed to corroborate these findings.

Moturi C, Karuga E, Orwa D. "Leveraging Big Data Analytics." International Journal of Big Data Management. 2021;DOI: 10.1504/IJBDM.2021.10036720. AbstractWebsite

This paper sought to study the extent to which telecoms within Kenya have adopted Big Data analytics to gain richer and deeper insights into their business dynamics in order to facilitate evidence decision making. A descriptive research design was employed and data was collected from ten leading telecoms using semi-structured questionnaires. The study found that Big Data could stimulate the economic growth, advance the productivity and competitiveness of the telecoms, as well as generate enormous benefits for customers. The factors with the highest significant effect on the adoption of Big Data analytics were identified. The practical implication of this paper is an increased understanding on what elements can promote Big Data adoption by large telecom companies. The study is beneficial to telecoms companies and any other organisations that would be looking at adopting data driven decision making to sustain competitiveness within the present uncertain setting.

Shagwira H, Mwema FM, MBUYA TO. "Lightweight Polymer–Nanoparticle-Based Composites.". In: Nanomaterials and Nanocomposites. Boca Raton: CRC Press; 2021. Abstract

The increasing demand for eco-friendly materials in various fields including the construction industry has led to increased efforts toward the development of more materials to suit such fields. In this work, a specific review of polymer–nanoparticle-based composites is presented with an emphasis on the nano-silica reinforcements. A background on applications, processing methods, and state-of-the-art review of the subject is presented. It is noted that there is limited literature focusing on the recycling of polymers using silica nanoparticle-based reinforcements for the construction industry. Gaps in the literature are identified, and the direction for future research focus is presented.

This work reports on a low cost, simple to prepare and chemically stable Raman substrates based on conductive silver paint smear. The substrates were characterized Raman spectroscopically and were found to be chemically stable within the first seven days when kept at room temperature as the spectroscopic profiles were unchanged. The substrates also suppressed the background signals emanating from glass centered around 750 cm−1 and 1370 cm−1 seen with 785 nm excitation and had negligible influence on Raman spectral profiles of rat’s blood samples applied onto them. The Raman spectral profiles of blood samples applied onto the substrates were found to be enhanced by a factor of 1.7 compared to those of thick blood smears on a clean microscope glass slide. The increased local field between the gaps formed by adjacent micron-sized silver solids in the paint smear were attributed to the observed intense signals observed from the blood samples applied onto them. The substrates were tried on Raman spectroscopic differentiation between blood from obese and normal; diabetic and normal Sprague Dawley rats. The prominent bands associated with fructose (638 and 812 cm−1), glucose (1127 cm−1) and branched chain amino acids (1033, 1217 and 1318 cm−1) were observed to vary in terms of intensity between the un-healthy (obese and diabetic) and healthy (normal) rats. The results reported here on the use of the easy to prepare, low cost Raman substrates have the potential of making surface-enhanced Raman spectroscopy accessible to less resourced laboratories in developing countries. The substrates can be applied in rapid Raman spectroscopic screening of various metabolic diseases.

Kamau JM, Mbui DN, Mwaniki JM, Mwaura FB. "LAB SCALE BIOGAS PRODUCTION FROM MARKET WASTES AND DAGORETTI SLAUGHTERHOUSE WASTE IN KENYA." International Journal of Energy and Environmental Research. 2020;8(1):12-21. Abstract

In this study, fruits and vegetable market wastes were used as substrates in biogas
production under psychrophilic, mesophilic and thermophilic conditions. Slaughterhouse waste
consisting of blood and diluted rumen fluid mixture was used as inoculum with seven days retention
time. Influence of C: N ratios of the unique mixtures of vegetables found in the market were
investigated. On average, the vegetable wastes found at the market contained >86% moisture, 5 -
12% volatile solid and 0.46 – 2.06% ash matter on a wet basis. The protein range was between
0.57 – 3.49% with high-fat content being recorded in avocado (Persea americana) wastes at
9.03%. The highest cumulative biogas was recorded in wastes mixture at 3500ml on seventh day
while low biogas yield was registered for wastes with C: N ratios greater than 35:1 like avocado
and lower than 10 like coriander and courgette wastes. The optimum operation pH was in the
range of 6.80 – 7.2.It can be concluded that the highest cumulative biogas was generated from
fruits/vegetable mixture at 3500ml in mesophillic conditions. This study recommends pH
adjustment to 6.8 – 7.2 in market wastes and C: N ratios of 20 – 25 for large scale biogas
production of wastes found in the Dagoretti Market.

Description
Dodonaea viscosa Jacq (Sapindaceae) is a medicinal plant with a worldwide distribution. The species has undergone enormous taxonomic changes which caused confusion amongst plant users. In Kenya, for example, two varieties are known to exist based on morphology, ie, D. viscosa var. viscosa along the coast, and D. viscosa var. angustifolia in the Kenyan inland. These two taxa are recognized as distinct species in some reports. This prompted us to apply metabolomics to understand the relationship among naturally occurring populations of D. viscosa in Kenya, and to identify compounds that can assist in taxonomic delineation of the different varieties of D. viscosa from different parts of Kenya. The phytochemical variability of Kenyan D. viscosa var. angustifolia populations collected from four different geographical regions (Nanyuki, Machakos, Nairobi, and Narok) and one coastal D. viscosa var. viscosa (the Gazi) were analyzed by LC-MS using a metabolomics-driven approach. Four known compounds, two diterpenoids (dodonic acid (1), hautriwaic acid lactone (3), and two flavonoids (5, 7, 4′, 5′-tetrahydroxy-3, 6, 2′-trimethoxyflavone (2) and catechin (4)) were isolated and purified from the Gazi coastal collection. The presence of these compounds and their relative abundance in other populations was determined by LC-MS analyses. Multivariate statistical analyses of LC-MS data was used for the visualization of the patterns of variation and identification of additional compounds. Eleven discriminant compounds responsible for separating chemometric clusters were tentatively identified. In an antimicrobial assay, hautriwaic acid …

Varicella-zoster virus (VZV) is under consideration as a promising recombinant viral vector to deliver foreign antigens including HIV. However, new vectors have come under increased scrutiny, since trials with adenovirus serotype 5-vectored (Ad5-vectored) HIV vaccine demonstrated increased HIV risk in individuals with pre-immunity to the vector that was thought to be associated with mucosal immune activation (IA). Therefore, given the prospect of developing an HIV/VZV chimeric vaccine, it is particularly important to define the impact of VZV vaccination on IA.

Abstract

Geomorphological and sedimentary records near the confluences of the Tana River and major tributaries draining the eastern slopes of Mt. Kenya and the Nyambeni Range, indicate impacts of Late Quaternary volcanic activity in their fluvial records. The main reconstructed event was triggered by a 366.9 ka basalt flow (40Ar/39Ar dated) which flowed along Kazita River from the Nyambeni Range blocking both Kazita River and Tana River near Kibuka Grand Falls, causing a temporary lake. Consequently, Tana River and Kazita River started to build volcanoclastic Gilbert type deltas. The preserved pro-delta sediments rich in trachytic pumice fragments display a mineralogical and age match with known Ithanguni trachytic tuffs, indicating delta build up right after a contemporary Ithanguni eruption. This trachytic eruption caused the deposition of lahars and fluvial volcaniclastic sediments in all river records draining the Eastern side of Mt. Kenya. The multiple lahars seem to be triggered by eruptions under glacial conditions (basalt age indicates MIS 10). The lava dammed lake was only short lived (estimated to have lasted only a few years to decades) and breached before a complete lake infill could occur. The current Kibuka Grand Falls can be viewed as the delayed incisional response of this lava dam breach, indicating that after >366.9 ka, Tana River is still responding and adjusting to this short-lived disruptive phase. The current Kazita River has re-incised adjacent to a MIS 4 basalt flow down into the crystalline Basement System rocks. The MIS 10 pre-volcanic sedimentary record indicates that more sediments were in the fluvial system during glacial conditions than during the interglacial conditions. An implication of our reconstruction is that the Late Quaternary fluvial record of Tana River is of only limited use to reconstruct uplift rates because reconstructed Quaternary incision rates are reflecting both volcanic disruptions as climate change trends of aridification and decreasing glaciation extents.

This study was carried out in selected public secondary schools in Kenya. It is on the realization that the work of the school Principal is not easy and many find themselves in leadership without proper preparation for the hard task. The school principals’ work is a high-stress job especially because he or she has to do virtually everything related to students, teachers, parents, subordinate staff and the community at large. This kind of leader would require extra-ordinary characteristics to be able to be successful. Majority of principals perform decimally in all the areas that spell success in secondary schools especially in discipline and academic performance. The purpose of this study was to find out how principals’ transformational leadership characteristics were correlates to effective school performance. Kouze’s and Posner’s leadership Practices Inventory(LPI) “self” questionnaire was used to measure Principals’ transformational leadership style. LPI “others” was used to triangulate the principals’ response with the teachers. The target population consisted of 72 Principals in public schools and 139 principals in private schools. There were also 1210 teachers in public secondary schools and 1500 teachers in private secondary schools in Nairobi County. The findings indicated positive correlations between the Principals’ transformational leadership characteristics with effective school performance.

Abstract

There have been drastic changes in land-use patterns in the Marsabit Forest Reserve (MFR) as a consequence of anthropogenic processes for livelihood improvement over time. The objective of this study was to assess the land-use and land-cover changes (LULCC), especially those related to the forest cover, in the MFR using multi-temporal Landsat images from Landsat 7 and 8 covering the period 1990 to 2017. Unsupervised and supervised classifications were carried out with the final classification done using the Maximum Likelihood Classifier for each period image to create six dominant land-use and land-cover classes (LULC) which included: shrubland, grassland, bare land, open forest, agriculture and settlement, closed forest, and wetland. The results showed that, between 1990 and 2010, the closed forest area had reduced from 19,599 to 9275 ha (−52.7%), open forest from 30,214 to 7345 ha (−75.7%), and shrubland from 83,288 to 65,212 ha (−21.7%). Over the same period there was, a corresponding increase in the grassland area from 35,233 to 56,066 ha (+58.7%), bare land from 19565 to 35,691 ha (+82.4%) and agriculture/settlement class from 12,842 to 24,072 ha (+87.5%). With the introduction of a forest moratorium illegalising consumptive forest use between 2010 and 2017, the closed forest area increased from 9275 to 12,133 ha (+30.8%), bare land from 35,691 to 42,275 ha (+15.6%) and shrubland 65,212 to 100, 452 ha (+35.1%), with a corresponding decrease in open forest area from 7345 to 1385 ha (−430%), grassland from 56,066 to 39,542 ha (−41.9%), and agriculture/settlement class from 24,072 to 7235 ha (−232.7%). The Focused group discussion (FGD) and Key informant interview (KII) respondents identified illegal logging, livestock incursion/foraging, inadequacies of Kenya Wildlife Service (KWS) and Kenya Forest Service (KFS) in forest management, forest excisions, firewood collection and illegal settlements in the Marsabit National Reserve (MNR) as the main drivers of LULCC. The study proposes the implementation of the ten-year (2015–2025) Marsabit Forest Ecosystem Management Plan in managing the drivers of LULCC in a bid to safeguard the ecosystem services (ES) provided by the MFR.

Unilateral tubal twin pregnancy illustrates and amplifies fundamental phenomena in developmental and
reproductive anatomy. Knowledge of this condition is also important to practicing obstetricians and
gynaecologists because it may constitute a diagnostic challenge, management dilemma, complex ethical
issues and increased risk for maternal morbidity and mortality (Benn et al., 2016). Previously considered
a rare occurence, recent data suggest that the condition is not uncommon (Svirsky et al., 2010). Indeed,
there are many reports (Vohra et al., 2014), including several from Sub-Saharan Africa (Makinde and
Ogunniyi, 1990). The case reported by Pulei et al., in Anat J Afr 2017; 6 (1) reveals several unique
features in the profile of risk factors, location, chorionicity and amnionicity, mode and time of
presentation, condition of the tube, diagnosis and fetal viability. There was no evidence of the
conventional risk factors (Sivalingam et al., 2011). This is consistent with several other reported cases
where it occurred spontaneously (Abi Khalil et al., 2016). In the present case, however, the patient had
multiple intramural and subserosal leiomyomata. Intramural myomata are known to disrupt uterine
contractility which may interfere with transport of the ovum and hence predispose to ectopic pregnancy
(Ajibade et al., 2012). It is probable, therefore, that this was the predisposing factor. Accordingly, it may
be useful to monitor patients with uterine fibroids for potential to suffer ectopic pregnancy. Family
history of twinning may have been useful, and is advocated, in view of the fact that it is one of the major
predisposing factors.

A simple, rapid isocratic liquid chromatography method was developed for the simultaneous determination of diphenhydramine, promethazine, chlorpheniramine, and ephedrine in cold-cough syrups commonly available in the Kenyan market. The influence of the percentage of organic modifier, ion pairing agent, buffer concentration as well as pH and column temperature on the selectivity with respect to analytes was investigated. Optimum chromatographic separation was achieved using a C18 Gemini NX column (250 mm × 4.6 mm, 5 μm) maintained at 40°C and a mobile phase comprising methanol –triethylamine-0.2 M ammonium acetate pH 5.0 -water mixture (50:0.15: 40:9.85, v/v) delivered at a flow rate of 1.0 mL/min. Upon validation, the proposed liquid chromatography method satisfied the International Committee on Harmonization acceptance criteria for linearity, sensitivity, precision, and robustness. The method was applied in the analysis of commercial samples obtained from Nairobi County, Kenya. The method can be used in routine analysis of cold-cough syrups containing the specified compounds.

Keywords: diphenhydramine; promethazine; chlorpheniramine; ephedrine, cold-cough syrups.

This article provides summary of sociodemographic and clinical characteristics of the kidney transplant donors and recipients from 2010-2015 from Kenyatta national hospital, Nairobi, Kenya, East Africa. Only living-related organ donation is practiced in Kenya. Accelerated kidney transplantation activities picked up in Kenyatta national hospital from the 2010. The duration from 2010-2015 has seen more kidney transplantations undertaken in the hospital than the ones done in the same hospital from 1984 when first transplantation was performed in Kenya to 2009. The data were extracted from manual medical records. There were about 120 kidney transplantations performed during this period but only 113 complete records were traceable. There were 113 medical records for both kidney graft donors and recipients from 2010-2015. Demographic characteristics for donors and recipients captured included age, sex, and donor-recipient relationships. The mean donor age was 32.94

"Lake level history of Paleolake Siriata and hydrological sub-basin connectivity in the Southern Kenya Rift during the African Humid Period (AHP).". In: American Geophysical Union, Fall General Assembly 2016. San Fransisco; 2016. Abstract

The AHP is one of the most dramatic examples of late Quaternary hydroclimatic change in the tropics. During this wet period numerous large and deep lakes existed in the eastern arm of the East African Rift System (EARS) as testified by paleo-shorelines and lacustrine sediments. The tempo of onset and termination as well as the duration of the AHP is a matter of ongoing research and are still poorly established for the Southern Kenya Rift. Here we present new paleo-shoreline and sedimentary evidence for the existence of a freshwater lake during the AHP to the east of alkaline Lake Magadi. The AHP lake - Paleolake Siriata - was a critical link in the paleodrainage network that connected the central with the southern Kenya rift lakes and northern Tanzania. To establish the timing and spatial extent of Paleolake Siriata we mapped elevations of paleo-shorelines and associated shoreline facies and diatomaceous lacustrine sediments along the former basin margins. Morphometric and topographic details were mapped using a dGPS and an UAV to create a DEM with a resolution of 5 cm to define shoreline elevations and the characteristics of the former basin outlet. Reservoir age-corrected radiocarbon dates of gastropod and bivalve shells and 40Ar/39Ar ages of pumice from the lacustrine strata provide the chronological framework of the Lake Siriata highstand. In addition, oxygen-isotope measurements of gastropod shells indicate past variations in the former lake water-balance. Paleolake Siriata formed abruptly immediately after the dry Younger Dryas interval and reached a maximum depth of 55 m and a surface area of 30 km2; during highstand conditions the lake overflowed into adjacent Lake Magadi while it received inflow from Lake Naivasha via the Kedong Valley and the Olorgesailie Basin in the north. This hydrological connectivity provides important context for the interpretation of the sediment records from the recently collected Olorgesailie-Koora and Lake Magadi drill cores.

A case study of the situation in Lamu, Isiolo and Siaya Counties . Nairobi: Land Development and Governance Institute ; 2016. Abstractlarge_scale_land_acquisitions_for_investment_in_kenya.pdfWebsite

Land acquisitions, either driven by foreign investments or domestic investment needs have continued to polarize opinions. When this research was proposed, it was premised on arguments by scholars Ruth Meinzen-Dick and Helen Markelova, who had analysed agricultural land deals, and argued that there were potentially two schools of thought about foreign acquisitions over agricultural land. Their school of thought regards them as “beneficial investments” whereby investors are viewed as bringing needed investment, possibly improved technology or farming knowledge, thereby generating employment and increasing food production. Meinzen-Dick and Markelova further argued that because these land acquisitions, foreign and domestic, are ongoing at a very fast rate, it is necessary for host countries to focus on what they can do to seize the opportunities and mitigate the risks associated with the deals.
During implementation of the research project in Kenya, it became clear that although prior illustrations of land deals included foreign acquisitions (e.g. Dominion farms), a government economic policy focusing on mega- infrastructure projects was driving (or expected to drive) a much higher pace of land acquisitions either for primary infrastructure, or for the economic activities that flowed from the primary infrastructure. This is in the context of the Lamu South Sudan Ethiopia Transportation Corridor (LAPSSET) project, which is a flagship means for realization of Vision 2030; Kenya’s current national development plan. Thus, a national conversation is necessary to debate the crucial question of how to provide safeguards to protect the interests of local communities directly affected by these investments, including compensation of land that is taken, and their place in the socio-economic and environmental continuum of investment projects from design to implementation.
The following findings and recommendations have resulted from this research, and it is anticipated they will be valuable in setting the agenda and tone of such a useful national conversation, as well as tangible actions:

A. Lessons, Conclusions and findings requiring policy level interventions

1. Regularization of landholding and tenure systems.
The absence or weakness of formal landholding, and land registration systems was evident in most of the research sites, in Isiolo and Lamu. This is despite Kenya having put in place new land laws in 2012 to give effect to constitutional provisions to protect land rights. This has resulted either in emergence of informal land administration and conveyance systems (Lamu), or the emergence of a complex system of formal land allocation that brings about multi-allocation of land through repeated issuance of allotment letters, (Isiolo), or non-adjudication and registration of community lands (Isiolo, Lamu). In either instance this results in undermining security of tenure, and enhances the vulnerability of concerned communities who will face difficulties securing their interests in the land ahead of any large scale land acquisitions, due to the entry of speculators, and persons interested in grabbing the land by being first to obtain formal registration. The Kenyan national government should consider partnering with the County government in Isiolo in order to identify the nature and extent of, and take steps to resolve the problem of multi-allocations of land there. In addition, putting in place a programme for regularization of tenure rights by addressing the challenges of those without title is important as it will enhance the security of tenure of people affected by compulsory acquisition.

2. Enhancing tenure of certain communities through implementation of the provisions of Community Land Act.
This conclusion is drawn from findings in research amongst the Aweer (Bargoni), and Turkana communities (Ngare Mara) where residents expressed apprehension over their tenure security in the face of land acquisition for LAPSSET infrastructure. This is because the land has not been (fully) adjudicated or registered in favour of the community notwithstanding existence of the Land (Group Representatives) Act that preceded the 2016 community land law. It is recommended that the government expedites the application of the provisions of the Community Land Act for the Lamu and Isiolo communities faced by these land acquisition projects as a first step to guaranteeing the beneficial interests of the community members, first by protecting tenure rights, and subsequently providing for equitable community land governance mechanisms.

3. Clarification on the practice and methodology of valuation of land and non-land assets for compensation.
The repeal of the Land Acquisition Act, and with that the Schedule that defined the methodology of valuation of land requires to be resolved. In any event, based on the analysis in the research, and findings, there is need to formally resolve the entitlement to compensation for persons without legal title. In addition, it is imperative for Kenya to state in law or regulations the methodology to be applied in valuation of non-land assets, including the loss of livelihoods. Application of the full replacement cost methodology, as discussed, provides a viable option because, in addition to anchoring on the market value of the land, the replacement cost approach extends compensation to non-land assets, using the real cost of full replacement, and not factoring in any depreciation of the non-land assets being replaced, and takes into account all the transaction costs of purchasing (conveyancing fees, etc), or logistical costs of replacement of non-land assets.

4. Internalization of resettlement safeguards principles and practice into Kenyan law of compulsory acquisition of land
A review of the current legal situation in Kenya concerning compulsory acquisition of land discloses the absence of safeguards governing interaction with host community, as well as involuntary resettlement safeguards in the event of displacement by land acquisition. This includes exploring the possible application of an FPIC process that emphasizes the quality and meaningfulness of affected community participation, including the impact that views obtained during consultations have on the final decision. Equally critical is the decision to vertically integrate the process by requiring the consultation of the affected public during project planning. In the sense of feasibility studies, and project designs, this suggests that community participation may add value to the process by being conducted much earlier on in the process, and contribute to analysis of project sites, and alternatives.

For practical purposes, Kenya could consider a legal requirement for a national Resettlement Policy Framework (RPF) that would govern internalization of resettlement safeguards, including participation of communities. Key to this is that if a Resettlement Action Plan (RAP) is required, in terms of EMCA, both the RAP and RPF would have undergo a Strategic Environmental Assessment thereby providing a means for risk assessment in advance of major implementation steps being underway.

5. Policy linkage of investment promotion rules with investments flowing from land acquisitions to secure community benefit through contracts and business models
At a policy level, it is important for Kenya to revisit, in a framework sense, how to use investment promotion rules and binding contracts to safeguard socio-economic, environmental benefits and livelihoods of local communities. This is mainly in context of the continuum of an investment, from land acquisition, and during its implementation. The Investment Promotion Act, while addressing the benefit to Kenya threshold, is not aggressively applied, and as evidenced by the Dominion contracts, critical socio-economic safeguards were not included. A clear policy evaluation of business models application, either contracts in the context of farming investments, or other types, should be undertaken and public disclosure of the proposed business model(s) should be undertaken early enough, to ensure affected project communities do not experience anxiety over their future.

This could be done in context of section 12 of the Land Act, which requires the National Land Commission to make regulations to govern how investments on public land will safeguard community benefits and livelihoods. The details of these considerations have been discussed at length earlier in this report.

6. Regulations to regulate methodology for assessment of just compensation
Kenya is currently engaged in a number of infrastructural projects that call for the compulsory acquisition and compensation of land. As noted in the study, Section 111 of the Land Act requires the National Land Commission to develop rules to regulate the assessment of just compensation where land is compulsorily acquired. As at the time of this report, these rules had not yet been developed. The rules will help to standardize the methodology for the anticipated assessment and make the process more predictable and, in an environment where the government is involved in the development of infrastructure calling for massive compensation of compulsorily acquired land, the development of these rules should have been accorded priority.

It is however noted that regulations to operate the entire Land Act have not yet been developed. Perhaps the development of these regulations, and the rules to govern assessment for just compensation, may have been delayed by the amendments recently effected to the Land Act. Now that the amendments were concluded, it is recommended that the development of the rules to govern the assessment of just compensation payable to landowners affected by large scale investments on land be expedited.

B. Lessons, conclusions and findings requiring direct actions at community level
In this category, the conclusions and findings are drawn to highlight matters that directly affect the voice and equitable benefit or participation of affected local communities, either in land acquisition process, or in the continuum of investments introduced in their midst.

1. A community dissemination manual for transfer of knowledge about land laws, policies and land administration processes
In focus group discussions held in the course of field work, the research team got similar feedback multiple times that the (potentially) affected “had heard” on radio, or through other fora that Kenya had new land laws in place, they did not really know the content of these laws. A similar sentiment was expressed with regard to knowledge of details about the components of the various LAPSSET projects. Communities indicated that they would want to have some form of civic education on this, especially regarding tenure rights, the land administration system (surveying, adjudication and registration), the implications and contents of the new community land law, and legal protection of community rights during land acquisition. One key finding was a preference by community members to have some of their own members trained in order to pass the knowledge to the communities, a sentiment that arose from a desire to receive information from a trustworthy source who was part of the community. Another finding was that community members did not have clear details on available grievance mechanisms on the land administration system, and while some had managed to access the National Land Commission, they lamented that it was based in Nairobi.

This finding suggests there is a need to develop a basic community dissemination manual, that includes a provision for empowerment of community based trainers (through a Training of Trainers concept). In such an approach, the dissemination manual can be published in simple language, including translation to Kiswahili or local languages where preferable.

2. Enhancement of meaningful public participation in the entire continuum through effective consultations and disclosure of relevant information

In order to enhance the voice of the community ahead of any process of land acquisition, it will be helpful to integrate a constructive and meaningful process of consultation with potentially affected communities, from early on during project planning, feasibility studies to onboarding of investments. This would particularly aid in providing value on local circumstances and risks that may not be obvious to technical teams. Occurrences such as in the Isiolo Kiwanjani settlement (displaced for the airport) where residents of Kiwanjani Zone G Squatter complained that maps generated during the acquisition process continued to record their land as being part of the airport complex despite there being a 75 feet road between the airport boundary, and the plots in question, would be avoided.

Enhanced community participation would further provide a valuable avenue through which the [potentially] affected local community can enhance its voice by having an opinion (which is taken into account) early on in the stages of the project design. However, this approach would also require protection from speculative behavior, that could result in an artificial increase in market value of land, due to market behavior triggered by anticipation of a project, and land acquisition. Access to information requires that this type of information is made available to the public, but in order to control speculative behaviour that drives up the cost of land compensation, government can apply the new 2016 Access to Information Act to sieve out aspects that are either confidential or considered deliberative and therefore not to be publicly disclosed. Another helpful approach would be to undertake the feasibility studies focusing on multiple alternative sites, without showing preference for any particular site.

Meaningful community participation requires a legal or policy definition of how to ensure consultations are effective. This could include possibility of requiring consulting (public) agencies to return to the host community and disclose how they considered the various opinions, and provide feedback. The community dissemination manual proposed above would provide a valuable tool through which to structure techniques that affected local communities can apply in order to have meaningful consultations.

3. Promotion of Networking by Project Affected communities in various parts of Kenya to build knowledge and exchange thoughts
There are multiple instances of compulsory acquisition of land in Kenya (e.g. For LAPSSET projects), or the allocation of land by government for private investments (Siaya – Dominion). The processes are at various stages, either at conceptual point, or having gone through various steps of acquisition and onboarding of investments. Equally, others are complete and the investment has been operational for a number of years. In all these cases, there multiple lessons to be learnt between the various affected local communities. In both Lamu and Isiolo for instance, the research engaged with multiple focus groups drawn from within the same project locality but in different geographical sections – and there was evidence that there was no integrated system to promote consultations and learning from each other. Further, even where acquisition and investments have been undertaken in separate parts of the country, people from Isiolo or Lamu could learn coping techniques from those in Siaya, or by learning the adverse impacts in Siaya, become more interested in enhancing their voices in the local context to avoid a similar outcome. Therefore, the idea of a network that brings together representatives of the various communities is useful to consider. Such a network would also include policy makers drawn from the national and county governments. Already in most of these local communities, the research observed that chiefs (who are national government administration officers) are an integral part of the community process. Learning forums could be organized, and a feedback process put in place such that when representatives return to their local communities, they can provide details to their neighbours. Such a network would however require that policy makers also commit to provide valuable information and feedback to any questions and problems raised by participating communities.

An alternative to utilization of physical meetings for such a network is application of internet-based technology. In this case, a network can be developed through low cost options, such as through the WhatsApp Platform. Although this requires internet access through a smartphone, the Land Development and Governance Institute has been piloting a WhatsApp based platform that creates a Network aptly named Community Land Matters. The experience with this platform is discussed at length in section 9.

4. Involvement of Women in Community Interventions
The study exposes some good lessons in the involvement of women in community interventions and leadership on communal land rights. It was instructive that for instance in the discussion with the Aweer group in Bargoni, Lamu, some women participants in the focus group discussions were very active and made crucial contributions. In addition, the women also made distinguished contributions too during discussions with the Turkana community at Ngare Mara, Isiolo County, where critical leadership positions in the community are held by women.

Yet, the two communities, like many others in Kenya, are largely patriarchal. This experience provides a good benchmarking lesson that, despite the cultural practices that have informed many communities in the past, given opportunity, women may play critical roles in helping communities protect and mitigate their communal land rights where circumstances so demand.

5. Compensation to “occupants in good faith” without title to land
As noted in the study, Article 40(4) of the Constitution of Kenya states that ‘provision may be made for compensation to be paid to occupants in good faith of land acquired under clause (3) who may not hold title to the land”. While the rules to govern how the discretion implied by this Article are yet to be developed, the study reveals that the State has exercised this discretion positively in the studied Port site in Lamu and the Airport site in Isiolo. Despite land owners not holding title to their land in the two places, cash-for-land and land-for-land compensation was made to the claimants in Lamu and Isiolo respectively.

These are good precedents for other parts of the country where formal processes to register communal land have not been applied or completed. Lessons learnt from these two Counties may be borrowed to inform and improve similar compensation exercises elsewhere.

6. Protection of interests of legitimate beneficiaries during compensation

Incidents were recounted of husbands and fathers pocketing the proceeds of compensation and departing home with the entire compensation sum. This leaves the wives and children vulnerably exposed and without alternative livelihoods. Such people become a problem for the community and State. To avoid such negligence, the government should consider regulating the release of compensation funds. The practice under the Land Control Act Chapter 302 of the Laws of Kenya which regulates transactions of agricultural land could be borrowed. Though not written into the law, Land Control Boards always require the proprietor’s spouse to be in attendance before approval to any application for approval of a transaction such as subdivision or sale of family property. And where they are in doubt about the facts to any application, they will usually refer to an area elder or the Assistant Chief for pertinent information in an effort to ensure that spouse and children are in agreement. Such a procedure could be enforced in the case of compensation following acquisition.

It is recommended that the Government, in liaison with the National Land Commission, puts in place modalities to explore how a similar social safeguard procedure could be instituted in the proceedings for compensation under the Land Act to protect legitimate beneficiaries in instances where acquisition of land for projects has to be done with requisite compensation to landowners.

7. Preservation of indigenous and local knowledge:
Project activities involving large scale land acquisition have the inevitable consequence, in some cases, of interfering or totally defacing available traditional/indigenous knowledge from the affected site. This is the case in some parts of Lamu and Isiolo where invaluable oral and cultural knowledge, including some cultural sites, have been preserved over the years. In any event, if enhanced community participation is adopted, and a threshold placed to examine if the participation is meaningful, the indigenous and local knowledge of the communities will also benefit the project at the point of local risk assessment. In this case, recording of such knowledge can be undertaken for posterity use.
It is therefore recommended that the implementation of such projects be preceded by a quick knowledge mapping to determine and document such knowledge before destruction or adulteration, together with enhanced community participation. Where possible, such knowledge can be proactively preserved in collaboration with the relevant state organs. Such a mapping can still be done for the LAPSSET Corridor and Isiolo Resort City before implementation takes off.

In the coming century the world's high tropical mountains are predicted to experience a magnitude of climate change second only to the Arctic due to amplification of warming with elevation in the tropics. Proxy data suggest that substantial changes in tropical temperature and hydroclimate also occurred during the last deglaciation, the most recent time period when rising atmospheric CO2 concentrations caused large changes in global climate. Determining whether the rate of temperature change with elevation (the lapse rate) was different from today during the Last Glacial Maximum (LGM) is therefore critical to understanding the future of tropical mountain environments and resources. Here we present a new 25,000-year temperature reconstruction based upon organic geochemical analyses of sediment cores from Lake Rutundu (3,078 m asl), Mount Kenya, East Africa. Through comparison with regional reconstructions of lower elevation temperature, we show that LGM cooling was amplified with elevation and hence that the lapse rate was significantly steeper than today. Comparison of our lapse rate reconstructions with equilibrium line altitude reconstructions from glacial moraines indicates that temperature, rather than precipitation, was the dominant control on tropical alpine glacier fluctuations at this time scale. Nevertheless, our results have important implications for the tropical hydrological cycle, as changes in the lapse rate are intimately linked with changes in atmospheric water vapour concentrations. Indeed, we attribute the steeper lapse rate to drying of the tropical ice-age atmosphere, a hypothesis supported by palaeoclimate models. However, comparison of our data to these simulations indicates that state-of-the-art models significantly underestimate tropical temperature changes at high elevation and therefore the lapse-rate change. Consequently, future high-elevation tropical warming may be even greater than currently predicted.

comABSTRACTSeborrhoiec Keratosis (SK) is one of the most common benign neoplasia of the eyelids, usually affecting elderly females. Typically, the lesions start as discrete, tan-dark brown, flat lesions starting on the face and progressing to other sun-exposed areas. The natural progression is generally an increase in size, thickness and pigmentation of these lesions. A variant of SK, Dermatosis Papulosa Nigra (DPN), has been described in black people, characterized by an earlier and more severe manifestation with multiple, profuse lesions. The diagnosis is clinical, although histopathological examination may be sought to confirm the diagnosis. These lesions are benign and usually only removed for cosmetic reasons. However, in some patients, concern or discomfort may warrant removal. Cryosurgery, electrodesiccation, curettage or shave excision are all effective methods of management. When eyelid lesions are excised, the resulting anterior lamellar defect can be repaired by primary closure, local skin flaps or Full-Thickness Skin Grafts (FTSG). We report a 60 year old female patient who presented with DPN and thick pigmented lesions on the eyelids of both eyes, causing mechanical ptosis, left lower lid ectropion and interfering with vision. She was successfully managed with excision and lid reconstruction for both eyes.Keywords: Seborrhoiec keratosis, Dermatosis papulosa nigra, Eyelid tumours, Eyelid reconstruction, Eyelid excisional biopsy, Glabellar flap INTRODUCTIONSeborrhoeic Keratosis (SK) is one of the most common benign neoplasia of the eyelids1. It usually affects elderly people, with a female preponderance and some cases of reported family history2. The exact cause is unknown and has been linked to sunlight exposure3. Typically, lesions are small, discrete and tan-brown flat macules, most frequently on the face and trunk4. With time, these lesions exhibit increase in size, thickness and level of pigmentation5. As they grow, the lesions become papules with the characteristic verrucous “stuck-on” appearance4. A variant of seborrhoiec keratosis, Dermatosis Papulosa Nigra (DPN) has been described in black people2. This variant manifests earlier, with multiple and profuse lesions which are larger, thicker and exhibit a more chronic and worsening course than classic SK. SK lesions are benign and do not usually require removal5. However, many patients present to dermatologists due to concern about possible skin malignancy when there is growth or increased pigmentation of the lesions6. Reasons for removal include cosmetic reasons, discomfort, itchiness or documented growth in the lesions. The diagnosis is clinical in majority of cases. However, especially if lesions are going to be removed, histopathological confirmation of the diagnosis may be sought. Histology of lesions is characterized by hyperkeratosis, papillomatosis, acanthosis with intraepithelial horn or pseudohorn cysts3. There are several options for

This article provides summary of sociodemographic and clinical characteristics of the kidney transplant donors and recipients from 2010-2015 from Kenyatta national hospital, Nairobi, Kenya, East Africa. Only living-related
organ donation is practiced in Kenya.
Accelerated kidney transplantation activities picked up in Kenyatta National hospital from the 2010.
The duration from 2010-
2015 has seen more kidney transplantations undertaken in the hospital than the ones
done in the same hospital from 1984 when first transplantation
was performed in Kenya to 2009. The data were
extracted from manual medical records. There were about 120 kidney transplantations performed during this
period but only 113
complete
records were traceable.
There were 113 medical records for both kidney
graft donors and recipients from 2010-
2015. Demographic
characteristics for donors and recipients captured included age, sex, and donor
-recipient relationships. The mean
donor age was 32.94±8.52 years, median age of 32years with minimum donor age of 20 yea
rs and maximum of
54 years. Fifty five percent (54.90%) of the donors were males. Among the recipients, the mean age was
39.15
±12.68 years, median age of 36 years with the minimum recipient age of 14 years and maximum age of 66
years. Three in every four (
74.30%) of recipients were males. First degree relatives contributed 85.60% of all
the donors, with brothers and sisters to the recipients contributing almost equally (31.9% and 29.2%)
respectively
. The recipients clinical characteristics include the prim
ary disease, where hypertension and
glomerular diseases contributed 85.0% while diabetes mellitus contributed 13.30% of the documented primary
morbidity. Haemodialysis was the only modality of renal replacement therapy with a mean duration of
2.39±1.63 yea
rs and modes of 2 and 3 years. The most popular vascular access for dialysis was permanent
catheter (58.40%) with arteriovenous fistu
lae at 25.70%. Blood group O Rhesus positive was the commonest
among donors and recipients (70.80% and 53.10% respectively
). Blood transfusion was very common among
the recipients before and around transplantation. (51% and 68% respectively). The HLA
-A,
-B,
-DRB1
first and
second loci
match between the donors and recipients were zero match at 5.30%, one match at 9.70%, two
ma
tches at 11.50%, three matches at 38.10%, four matches at 20.40% five matches at 2.70% and six matches at
12.40%. All the transplantations were first kidney transplants
apart fro
m one case.
In our living
-related kidney transplantation programme, the donor
s are younger than recipients with males being
transplanted more than females. First degree relatives dominate the donation
. The commonest cause of the
ESRD was glomerular diseases and hypertension. The program shows plausible feasibility of organ transpla
nt
where the most po
pular modality of renal replace
