Genotypic Variation for Tolerance to Low Soil Phosphorous in Common Bean under Controlled Screen House Conditions  [PDF]
Annet Namayanja, Johnson Semoka, Robin Buruchara, Susan Nchimbi, Moses Waswa
Agricultural Sciences (AS) , 2014, DOI: 10.4236/as.2014.54030

Production of common bean (Phaseolus vulgaris) is often limited by the low availability of soil phosphorus (P). Identification of common bean genotypes adapted to low phosphorus (P) availability may be a feasible strategy to overcome the poor plant growth and production in P-deficient soils. Genetic variation for P response of thirteen common bean genotypes was studied under screen house controlled conditions using triple super phosphate as P source. The common bean genotypes varied in leaf area, shoot mass, root mass, total root length, basal and lateral roots production, shoot P concentration and P uptake under phosphorous deficiency and high phosphorous. All the measured variables were significantly correlated with each other, which in turn were correlated to P uptake. Generally the large-seeded genotypes RWR 1946 and RWR 2075 appeared to have the best growth, hence superior P efficiency under low P availability, while at the same time they were more responsive to added P. These results complement the earlier field based observed tolerance to low soil phosphorous of the selected genotypes under the BILFA strategy.

Application of Magnetic Survey in the Investigation of Iron Ore Deposits and Shear Zone Delineation: Case Study of Mutomo-Ikutha Area, SE Kenya  [PDF]
Aaron K. Waswa, Christopher M. Nyamai, Eliud Mathu, Daniel W. Ichang’i
International Journal of Geosciences (IJG) , 2015, DOI: 10.4236/ijg.2015.67059
Abstract: The main objective of this research was to use ground magnetic survey to delineate shear zone and iron ore deposit within the Neoproterozoic rocks of Mutomo-Ikutha area of south eastern Kenya. Total field magnetic data was recorded by using high resolution proton precision geometric magnetometer which recorded total components of the ground magnetic anomaly data running through sixteen traverses. The field data was qualitatively and quantitatively interpreted and the results gave values for the total component measurements of ground magnetic anomaly that varied between a minimum negative peak value of about 250 nanoTesla and a maximum of about 1000 nanoTesla. 550 nanoTesla was considered to be threshold of the iron mineralization within the area. The results indicated that the western part of Mutomo-Ikutha was sheared, faulted and contained iron ore mineralization trending in the north-south direction. Areas with high anomalous values were geochemically proven to contain magnetite.
Evaluation of the Factors Controlling Concentration of Non-Condensable Gases and Their Possible Impact on the Performance of Geothermal Systems: Case Study of Olkaria Wells in the Kenyan Rift Valley  [PDF]

Abstract: The Olkaria geothermal field is located in the Kenyan Rift valley, about 120 km from Nairobi. Development of geothermal resources in the Olkaria area, a high temperature field, started in the early 1950s. In the subsequent years numerous expansions have been carried out with additional power plants being installed in Olkaria. These include a binary plant at Olkaria South West (Olkaria III) in 2000, a condensing plant at Olkaria North East (Olkaria II) in 2003, another binary plant at Olkaria North West (Oserian) in 2004 and finally condensing plants in the year 2014 within East production field (EPF) and Olkaria Domes (OD) areas. The total generation from this field is about 730 Mw. The study considered samples from 4 producing wells from 3 fields of the Olkaria geothermal area (OW-44 from the Olkaria East, OW-724A from the Olkaria North East, and OW-914 and OW-915 from the Olkaria Domes field). The chemical data were first analyzed using SOLVEQ. This helped in the determination of the equilibrium state of the system, the reservoir temperatures and the total moles to be run through CHILLER. The run CHILLER considered the processes that have been proven to be occurring in the Olkaria fieldi.e., boiling and condensing processes, fluid-fluid mixing rocks and titration resulting from water-rock interaction. The effects on gas evolution were evaluated based on the resulting recalculated gas pressures. The results indicate that the gas species are not in equilibrium with the mineral assemblages. The CHILLER evaluation shows boiling as the major process leading to the evolution of gases. OW-44 had the least gas concentrations, arising from the considered reservoir processes due to degassing, and near surface boiling, besides the removal of NH3, H2and H2S are through the reaction with steam condensate. The gas breakout is most likely in OW-914 and least in OW-44. The study
Structural Controls on the Geochemistry and Output of the Wells in the Olkaria Geothermal Field of the Kenyan Rift Valley  [PDF]

Abstract: The Olkaria geothermal field is located in the Kenya Rift valley, about 120 km from Nairobi. Geothermal activity is widespread in this rift with 14 major geothermal prospects being identified. Structures in the Greater Olkaria volcanic complex include: the ring structure, the Ol’Njorowa gorge, the ENE-WSW Olkaria fault and N-S, NNE-SSW, NW-SE and WNW-ESE trending faults. The faults are more prominent in the East, Northeast and West Olkaria fields but are scarce in the Olkaria Domes area, possibly due to the thick pyroclastics cover. The NW-SE and WNW- ESE faults are thought to be the oldest and are associated with the development of the rift. The most prominent of these faults is the Gorge Farm fault, which bounds the geothermal fields in the northeastern part and extends to the Olkaria Domes area. The most recent structures are the N-S and the NNE-SSW faults. The geochemistry and output of the wells cut by these faults have a distinct characteristic that is the N-S, NW-SE and WNW-ESE faults are characterized by wells that have high Cl contents, temperatures and are good producers whereas the NE-SW faults, the Ring Structure and the Ol’Njorowa gorge appear to carry cool dilute waters with less chloride concentration and thus low performing wells. Though the impacts of these faults are apparent, there exists a gap in knowledge on how wide is the impact of these faults on the chemistry and performance of the wells. This paper therefore seeks to bridge this gap by analysis of the chemical trends of both old wells and newly drilled ones to evaluate the impacts of individual faults and then using buffering technique of ArcGis estimate how far and wide the influence of the faults is. The data was obtained after the sampling and analysis of discharge fluids of wells located on six profiles along the structures cutting through the field. Steam samples were collected with a stainless steel Webre separator connected between the wellhead and an atmospheric silencer on the discharging wells whereas the analysis was done in house in the KenGen geochemistry laboratory. The results indicates that Olkaria field has three categories of faults that control fluid flow that is the NW-SE trending faults that bring in high temperature and Cl rich waters, and the NE-SW trending Olkaria fracture tend to carry cool

International Journal of Geosciences (IJG) , 2017, DOI: 10.4236/ijg.2017.85039
Abstract: Remote sensing investigations combined with Geographical investigation systems (GIS) provide a rapid and cost-effective method for prospecting hydrothermal and geothermal systems. Most geothermal systems in Kenya are found in remote areas where accessibility is difficult. This study was carried out on Paka volcano which is located in the Kenyan rift valley. The aim of the study was to use remote sensing and GIS to investigate hydrothermal minerals and structures associated with geothermal activities. The study involves use of Landsat TM image classification using ENVI 5.1 and ArcGIS. Lineament extraction was done using PCI geomatics 2015 while Rose diagrams were generated using Rockworks 16. The research has shown that lithological, hydrothermal mineralization and structural maps can be generated form Landsat TM images using remote sensing and GIS. It has been shown that faults trend in the Northeast, North and Northwest direction. Hydrothermal minerals that are rich in iron and clays occur on Paka volcano mountain and its neighbouring areas.
Poverty in Africa and the Forces of Change: Reflections on Rawls Difference Principle  [PDF]

Abstract: Africa is no doubt one of the continents endowed with resources necessary for the achievement of development in all areas. The pre-colonial era as crude as being described, was to a large extent characterized by values for self sustenance. However, the crises being witnessed in Africa as it manifest in hunger, lack and scarcity over these years have been on one hand, argued to have resulted from the contact Africa had with the external forces of colonialism. These forces as claimed ushered in unbridled economic system with its implications on value system of brotherhood, reciprocity and fraternity among others. On the other hand, the internal forces which manifest in corruption, mismanagement and bad leadership, have totally grounded the development to a halt. This paper critically examines these forces of change, with the aim of identifying the missing link and attempt to suggest ways towards charting a new course in order to regain the values. The paper applies John Rawls Difference Principle as a theoretical framework, capable of ensuring that benefits and burdens are fairly distributed for the advantage of every one, more especially the less privileged in society. This would enhance the attainment of a stable social order as it promotes the ideals of reciprocity and fraternity in society.
Mathematical Modelling of Bloch NMR to Explain the Rashba Energy Features  [PDF]
Moses E. Emetere
World Journal of Condensed Matter Physics (WJCMP) , 2013, DOI: 10.4236/wjcmp.2013.31015

The Bloch NMR as an analytical tool was able to address the fundamental features in the learning of spintronics. Beside confirming past assertions on the Rashba spin-orbit interaction, thermal motion of hole and electron spin and features of the quantum well, it was also able to explain the condition necessary for Rashba splitting within the quantum well. When the Rashba energy is 43 meV, it modified the Ehrenfest’s theorem to hold for an external magnetic field. The confinement potential which is the strength of the Rashba spin-orbit interaction was shown to be controlled magnetically.

Moses N. Kiggundu
Beijing Law Review (BLR) , 2013, DOI: 10.4236/blr.2013.44020

This paper provides a comparative longitudinal assessment of legal and judicial reforms relevant for China-Africa economic relations. It draws on and extends aspects of institutional and organizational theory, focusing on the concepts of convergence, alignment, hybridization, and institutional voids. Data were obtained from publically available databases from reputable international organizations including the World Bank and the World Economic Forum. Results point to areas where China has made progress more than Africa, and areas where serious capacity and performance gaps remain, especially for individual African countries. The paper provides a brief discussion of the implications for the need to build organizational capacities necessary for strengthening China-Africa economic law and advancing mutually beneficial economic relations and concludes by identifying research limitations, and areas for future research.

A Philosophical Appraisal of the Concept of Common Origin and the Question of Racism  [PDF]
Moses Oludare Aderibigbe
Open Journal of Philosophy (OJPP) , 2015, DOI: 10.4236/ojpp.2015.51003
Abstract: The quest for a definite answer to some certain ageless philosophical questions such as: What is man? What is his origin? What is his destiny? How is he like other beings in the universe, and how does he differ from them? These have up-till date; remain fundamental questions, which are begging for answers in all human societies. In spite of several attempts from the religious, scientific, cultural and sociological theories to explain the issue of common origin, the problem of racism with all its contradictions persists. This paper is to critically evaluate on one hand, the concept of common human origin, using the various theories to analyse the basis for its justification; on the other hand, examine the issues relating to racism, with the aim of arguing that the meaningfulness or meaninglessness of the universe must start from our understanding of human person and his existence. The philosophical method of conceptual clarification and critical analysis are employed to establish the view that man is the key to the understanding of the whole of reality. Thus, whatever disrespect human dignity regardless of colour, race or sex is to be absolutely rejected.
