Predicting daily streamflow in ungauged rural catchments: the case of Masinga catchment, Kenya
(Taylor & Francis group, 2007-04-01) Mutua, Benedict Mwavu.; Klik, Andreas.
Access to daily streamflow data at the catchment scale, is a central component of many aspects of water resources and water quality management. However, the majority of river reaches in many catchments in Kenya are ungauged or poorly gauged, and in some cases existing measurement networks are declining. Long-term continuous monitoring is not being done due to high costs of equipment maintenance. Therefore, there is a need for an alternative tool such as a catchment-scale hydrological model that is capable of predicting the daily streamflow. An approach is presented of predicting daily streamflow using a physically-based catchment-scale model, the geospatial Stream Flow Model (SFM). The SFM was developed using the “C” programming language and the user interface was developed using the Avenue script of the ArcView software. The SFM simulates the dynamics of runoff processes by utilizing remotely sensed and widely available global or local data sets. The model was applied in the Masinga catchment, Kenya, and the results gave a model performance coefficient of 0.74 based on the Nash-Sutcliffe statistical criterion.

Information needs of women refugees at Kakuma refugee camp in Kenya
(LAP Lambert Academic Publishing, 2013-06-19) Kilei, Ndukuh Charles
The number of civil wars worldwide has increased dramatically since the end of the cold war,(1943-1991)The global increase in civil wars is because of ethnic and religious conflicts (Quick;1995). Refugees in acute crisis leave their homelands suddenly with little prior planning and with no choice about their destination. Information is very important to every aspect of society and to understand the information needs of immigrants is indeed essential for librarians or service providers in order to provide better services to them. Fisher [et al..] (2004) have specifically recognized the fact that immigrants are generally perceived to be information poor, meaning they face major challenges with finding and using greatly needed everyday information. In fact, immigrants need information constantly of all types like every other person for the development of a person.This piece of work targets the women refugees Information needs,this is because women have unique information needs such health issues because they are more exposed to disease and other woman related complications. They are also prone to deprivation of rights and exploitation than their male counterparts.
Buckling Load of Thin Spherical Shells Based on the Theorem of Work and Energy
(IACSIT International Journal of Engineering and Technology,, 2013-06-25) Khakina, Peter Nyongesa
Thin spherical shells usually fail due to buckling. An empirical equation to predict their buckling load is derived based on the theorem of work done and energy released in the inversion of a section of a shell and nonlinear finite element (FE) modeling done using ABAQUS to determine their post-buckling behavior. It is observed that the initial buckling is sensitive to initial geometrical imperfections but the post-buckling load is little influenced. Therefore, the post-buckling load is used to predict a more realistic load as compared to classical buckling theory prediction
Sensitivity analysis and calibration of the modified universal soil loss equation (MUSLE) for the upper Malewa catchment, Kenya
(Elsevier, 2013-09-01) Mutua., Benedict Mwavu.; Odongo., V.O.; Onyando., J.O.; Becht, R.
Simulation models are widely used for studying physical processes such as surface runoff, sediment transport and sediment yield in catchments. Most models need case-specific empirical data for parameterization before being applied especially in regions other than the ones they have been developed. Sensitivity analysis is usually performed to determine the most influential factors of a model so that they can be prioritized for optimization. In this way uncertainties in model outputs can be reduced considerably. This study evaluates the commonly used modified universal soil loss equation (MUSLE) model used for sediment yield simulation for the case of the upper Malewa catchment in Kenya. The conceptual factors of the model are assessed relative to the hydrological factors in the model. Also, the sensitivity of the model to the choice of the objective function in calibration is tested. The Sobol' sensitivity analysis method was used for evaluating the degree of sensitivity of the conceptual and hydrological factors for sediment yield simulations using the MUSLE model. Nash-Sutcliffe Efficiency (NSE) and the modified Nash-Sutcliffe Efficiency (NSEm) are used to test the sensitivity of the model to the choice of the objective function and robustness of model performance with sediment data measured from upper Malewa catchment, Kenya. The results indicate that the conceptual factors are the most sensitive factors of the MUSLE model contributing about 66% of the variability in the output sediment yield. Increased variability of sediment yield output was also observed. This was attributed to interactions of input factors. For the upper Malewa catchment calibration of the MUSLE model indicates that the use of NSEm as an objective function provides stable results, which indicates that the model can satisfactorily be applied for sediment yield simulations.
Green ICT implementation in developing nations: personnel perspective
(Scholars Press, 2014) Wabwoba, Franklin; Mbugua, Samuel
Though ICT is contributing to the economy associated with innovations, inventions and rapid development in almost all aspects of human life, it is also responsible for climatic degradation. The rapid increase of ICT usage means more costs of doing business, energy consumption, and more environmental challenges. The rapidly changing technology and lack of their understanding has put a lot of pressure on both management and ICT personnel to implement them on a trial and error manner. This has limited the gains meant to be obtained from green ICT. The lack of appropriate alignment between the ICT personnel capacity and the workplace readiness poses more environmental and unsustainable resource utilization challenges. The book was informed by the G-readiness model. It discusses the green ICT technologies, the personnel awareness of green ICT, green ICT maturity, and workplace readiness for green ICT and the perceived barriers to green ICT implementations. It explains the extended G-readiness assessment and G-alignment models that when well applied are bound to enhance the implementations of green ICT. It is an excellent book for undergraduate and graduate studies for Green ICT courses.

Assessment of Nexus Between Features of School Culture and Student Deviance in Schools Within Bungoma County, Kenya
(Asian Journal of Educational Research, 2017-09-29) Nabiswa, Janet; Misigo, Bernard L.; Korir, Daniel
Whereas many schools have been known to exhibit strong school cultures that seem to drive academic excellence, deviant behaviour in schools continues to be a matter of global concern. Knowledge of the role school culture plays in mitigating deviance is vital for any prevention programme yet this has been missing. The study sought to address this gap by examining influence of features of school culture on student deviant behaviour in secondary schools of Bungoma County, Kenya. A sample size of 79 secondary school management was used from a study population size [N] of 504. Mixed research design was employed while sampling strategy was a blend of multiphase, stratified and purposive sampling. The data for the study was obtained through questionnaire, interviews, document analysis and direct observations. Results were analyzed using cross-tabulations, frequency tables, Chi square and simple linear regression. The sampled features of school culture were being applied in schools within Bungoma County and Chi-square tests revealed a significant relationship between features of school culture and student deviant behaviour prevalence in schools. However, regression analysis revealed a weak to moderate relationship between features of school culture and deviance levels. The study concludes that features of school culture influences student deviant behaviour prevalence hence other than direct punishment of deviants, school cultures with features loaded with preventive and corrective aspects should be embraced. The findings strengthen empirical view to education sector towards packaging school culture as an important variable to mitigate student deviance.
Adsorption Kinetics and Isotherms of Methylene Blue by Geopolymers Derived from Common Clay and Rice Husk Ash
(Physical Chemistry, 2017-10-07) Maingi, Francis M.; Mbuvi, H. M.; Ng’ang’a, M. M.; Mwangi, H.
With the onset of industrialization mankind has witnessed various environmental issues in the society. Industrialization has not only brought development and prosperity but eventually disturbed the ecosystem. It is currently estimated that 1.1 billion people in the world lack access to enhanced clean water supplies. Consequently, pursuance of sustainable materials and technologies for wastewater remediation is critical. Use of adsorbents for wastewater treatment is preferable due to their simplicity and cheap materials involved. Geopolymers are synthesized hydrothermally using alumina and silica which possesses amorphous surface for use as adsorbents. There is adequate information and reports in literature that indicate clay contain alumina and silica. Similarly, findings have shown that rice husk ash contains substantial amounts of silica. This work reports synthesis of geopolymers GP-1, GP-2 and GP-3 prepared by using different SiO2/Al2O3 ratios and consequently equilibrium and kinetics behaviour of adsorption of methylene blue. The geopolymers were characterized using FT-IR, EDS, XRD and SEM. Geopolymer adsorbents were subjected to methylene blue batch sorption experiments thate indicated the adsorption of MB increased with increased Si/Al ratio in geopolymers. The adsorption isotherms were described by Langmuir, Freundlich, Temkin and Sips isotherms. Data for adsorption of MB onto geopolymers fitted best in Sips adsorption model. Kinetic studies showed that Pseudo -second order model were more suitable than the Pseudo- first order model in explaining the kinetics of adsorption.

Clay-Rice Husk Ash based Geopolymers for Remediation of Pb (II) and Cd (II) from Wastewater
(Egerton Journal of Science & Technology., 2019-10-31) Maingi, Francis M.; Mbuvi, Harun Mbatha; Ng'ang'a, M M; Mwangi, Henry
Industrialization and technological advancements have led to the generation of numerous pollutants such as heavy metals into the aquatic ecosystem. These toxic compounds are extremely dangerous to human health and the environment due to their non-biodegradability, severe toxicity, ability to accumulate and contaminate ground and surface waters. Subsequently, pursuance of sustainable materials and technologies for better attainment of environmental sustainability is critical. This study reports the synthesis of geopolymers GP-1, GP-2 and GP-3 from different clays. Geopolymers were hydrothermally synthesized using clay and rice husks waste as an alumina and silica source respectively. The geopolymers were characterized using Fourier transform-infra red, energy dispersive spectrometry, X-ray diffraction and scanning electron microscope. Batch and gravitational column experiments using Pb (II) and Cd (II) ions were carried out. Increased metal ion uptake was recorded with raised Si/Al ratio of the adsorbents. The mean percentage uptake of 90.23 ± 0.4 and 89.63 ± 0.18 of Pb (II) and Cd (II) were achieved at pH of 4.0 and 5.0 respectively using GP-3. Langmuir, Freundlich and modified Langmuir Freundlich isotherms were used in equilibrium studies. Data for adsorption of Pb (II) and Cd (II) fitted best in the modified Langmuir Freundlich model. The highest adsorption capacities of Pb (II) and Cd (II) were 209.9 and 136.2 mg/g respectively, attained using GP-3. Based on the results obtained, geopolymers produced from common clay and rice husk waste displayed promising potentials in the removal of heavy metal ions from the aqueous phase. Considering the availability of raw materials for geopolymerization and the high metal ions uptake capacities of geopolymers, they can also be used as adsorbents for removal of heavy metals in industrial wastewater.
Implementation evaluation metrics for ERP solution: A case of Kibabii University
(IGI Global, 2020) Mbuguah, Samwel Mungai; Wabwoba, Franklin; Wanjala, Chrispus Kimingichi
Most institution of higher learning are implementing enterprise resource planning (ERP) in automating various activities. The architecture of most of the ERP is based on the service-oriented architecture (SOA) where each module can be called as service. In most of the contracts signed between the vendor and the university, payment is tied to the level of implementation. The question is how to then measure the level of implementation. This chapter proposes a metric that could be used. The metric was derived based on an acceptance test on each of functionality of module as per terms of reference. The result of a test was rated as a fail; the result was then coded such that a fail was assigned a zero (0), pass one (1), and query a half (½), from which a metric was derived which measures the level implementation.

(Journal of Accounting, Business and Finance Research, 2020-10-01) Kirwa, Tecla; Ngeno, Vincent
Purpose: following the Resource Based View Theory, this study explored whether firm innovation mediated the upshot of organization capital on firm performance in Kenyan insurance firms. Design / Methodology: the research surveyed 49 insurance firms in Kenya using explanatory research design. The hypotheses testing used Structural Equation Modelling. Findings: The outcome revealed that organization capital positively influences firm innovativeness and that firm innovation partially arbitrates the association between organization capital and performance of the firm. Practical implication: the outcome of the research suggested that for insurance firms to be innovative organization capital should be enhanced in terms of availability in the systems, databases, files, licenses or patents which is termed very important for implementation of innovation since such knowledge is the result of humdrum routine of employees, reminds usage process, flexible in usage for new contexts and more significantly it improves employees technology skills thus resulting to a better performance by the firm.
Effect of potassium dosage on selected growth parameters and yield response modeling on potatoes grown in Molo, Kenya
(Journal of Scientific Agriculture, 2020-10-07) Maingi, Francis M.; Mbuvi, Harun Mbatha
The Molo region of Kenya has experienced decreased potato acreage yields over the years. This has impacted negatively economic endeavors and food security of the region and Kenya at large. A preliminary study on the physical-chemical characterization of the soils indicated that they were deficient in the amount of available potassium. This finding was very important because the majority of the farmers in the region replenish phosphorous and nitrogen but not potassium. Subsequently, the present study was undertaken to determine the effect of replenishing selected farm soils with various potassium levels on the growth and productivity of ‘Shangi’ a variety grown in Molo Sub-county and ultimately determine the soil optimum potassium dose requirement. A field experiment was conducted with seven model-based K fertilizer treatments (0, 33.3, 41.5, 55.3, 133.3, 200 and 266.7 kg K2O/ha) and three replications in Randomized Complete Block Design (RCBD). The potassium sorption study was conducted using soil samples as adsorbent while varying the K+ concentration in solution. The data obtained were treated using both linearized and non-linearized Freundlich adsorption isotherms. The optimum potassium fertilizer rate was evaluated using yield response models (Quadratic, linear-plateau, quadratic-plateau, and square root). The results of the study showed that the increase in soil potassium levels led to a significant increase in growth and yield parameters. Aerial stem number, leaf number per plant, and plant height recorded increase with an increase in K levels. The sorption data were found to fit best in linearized Freundlich isotherm based on correlation coefficient values (R2) and error function analysis. The potassium buffering capacity ranged from 13.667-46.068 with a mean of 33.6 ± 17.4mg/Kg. The quadratic model fitted the data better than other models with R2 (0.9559) and SSE (18.237). K2O fertilizer application at 200 Kg/ha maximized the potato tuber yield to 30.111 Ton/ha. The result showed clearly that there is a need to adopt the use of potassium-based fertilizer according to soil requirements in this region to realize good tuber yield.
