Simple groups form the building blocks of all other groups and the class of all simple groups is given in a theorem known as classification of finite simple groups. The proof of this theorem, which was a monumental work in group theory involved several researchers and was completed in 1982. It is captured in 500 volumes. In an attempt to better understand and simplify the proof of this theorem, several researchers have embarked on studying the underlying structures of these groups.

Thermoelectric generators (TEG) offer promising opportunity of converting heat into electrical energy. There is the need to explore highly efficient thermoelectric (TE) materials with aim of improving the performance of TEG. Among the TE materials investigated, are Zintl compounds which have recently gained a lot of interest because of their high figure of merit. The structural, elastic, electronic, and optical properties of BaGe2As2 and BaGe2P2 have been studied theoretically, however their thermoelectric properties have yet to be documented.

Currently, the agricultural sector has been experiencing inorganic fertilizer shortages due to the disintegrating phosphate rock conventionally used as phosphorus source during fertilizer production. The rock disintegration has been caused by its consumption with mining. This has led to low food production amid the increasing human population. For this reason, the conventional inorganic fertilizers availed to the market are scarce and unaffordable because the conventional methods of their syntheses require large amounts of energy and resources.

Natural radioisotopes are present in all sanitary ware products used in building and construction. The primary source of outdoor radiation that residents of homes or workplaces are exposed to is these radioisotopes. Determining the radiation levels of sanitary wares in terms of production materials (ceramic and porcelain) and countries of importation of these items used in buildings is crucial. In this study, Thallium doped sodium iodide detector NaI(Ti) was used to obtain levels (226Ra, 232Th, and 40K) in twenty sanitary ware products.

Animal wastes specifically livestock and poultry waste are gaining mileage as an alternative to commercial nitrogenous fertilizers. Livestock and poultry manure however vary in the composition of macro and micro-nutrients, pH, and absorptivity. There was therefore need to combine different manure types for optimal plant growth because optimization of animal manure mixing ratios is among the methods of improving manure efficiency. However, optimization procedures are considered sophisticated by farmers and researchers.

The group 2^7: G_2(2), is an extension of an elementary abelian group of order 2^7 by the exceptional group G_2(2). There are eleven maximal subgroup conjugacy classes in the simple symplectic group Sp_8(2). The split extension group of the 2^7: G_2(2) of order 1548288 is one of the maximal subgroups Sp_8(2). In this study, the theory of Fischer-Clifford matrices to construct the character table of the maximal subgroup 2^7: G_2(2) of the affine subgroup Sp_8(2) is used.

Symmetry of a differential equation is a transformation that maps any solution to another solution of the system. In Lie’s framework such transformations are groups that depend on continuous parameters and consist of point transformations or point symmetries acting on the systems space of independent and dependent variables. Lie groups and its infinitesimal generators can be naturally prolonged to act on the space of independent variables. In this thesis, we present Lie symmetry analysis to solve a non-linear ordinary differential equation of an electric power flow model.

Performance contracting (PC) in Kenya can be traced back to 1993 when the government started implementing public sector reforms, Kenya’s Vision 2030 has recognized Pamong the key strategies to strengthening public administration and service delivery. In public secondary schools, the teachers have to undergo a continuous Teacher Performance Appraisal (TPA) which forms part of the Performance Contract that the Principal signs as a binding agreement between the school and the government.

Naturally occurring radioactivity has existed in our environment since the creation of the earth. 238U, 232Th and 40K radionuclides are found in significant concentrations in soils. These radionuclides pose exposure risks which can lead to health related problems like lung cancer and bone cancer especially when they exceed the recommended safety limits. A radiological assessment of 238U, 232Th and 40K in the top soils of Ahero paddy fields of Kisumu County was done using NaI(TI) gamma ray spectroscopy.

Superconductivity is the state of a material characterized by close to zero dc electrical resistance, hence infinite conductivity by the material, when the temperature of the material is lowered below the critical temperature () in a zero magnetic field strength. There are two categories of superconductors; s-wave superconductors that are isotropic and d-wave superconductors that are anisotropic. The microscopic theory of superconductivity by Bardeen, Schrieffer and Cooper (BCS theory) explains s-wave pairing of charges under ambient pressure but it fails to explain charge pairing under high pressure. Studies have shown that superconductivity in hydrides is due to electron-phonon mediation.

Natural radioactivity levels and radiation risks due to fallow and agricultural soils of Trans- nzoia County was measured. Trans-nzoia County is one of the counties in Kenya known for large-scale maize farming. This study analyzed natural radioactivity and radionuclides distribution in fallow and agricultural soils in Trans-nzoia County. Limited research had been done to assess the radiation levels due to primordial and anthropogenic processes in Trans- Nzoia County. The activity concentration levels of natural radionuclides (232Th, 238U, and 40K) in soil samples were analyzed using NaI (TI) gamma-ray spectrometry methods.

The unprecedented increase in anthropogenic activities coupled with the prevailing climatic conditions has increased the aerosol load over East Africa (EA). The aerosols have had detrimental effect to the local climate, human health and environment. There is therefore need for intensive characterization of aerosols properties over different domains, especially those that have lagged behind the rest of the world, such as EA. Given this, the present study has presented a spatiotemporal analysis of total aerosol optical depth (TAOD), absorptive aerosol optical depth (AAOD), scattering aerosol optical depth (SAOD) and direct aerosol radiative forcing (DARF) aerosol characteristics together with microphysical properties at distinct spatio-temporal scales over East Africa.
