On Characterization of u-ideals determined by sequences’’
(2013)The area of ideals is important in the study of Analysis, algebra, Geometry and Computer science. The various types of ideals have been studied, for example m ideals and h ideals. The m ideals defined on real Banach spaces ... -
2D-Euler Deconvolution and Forward Modeling of Gravity Data of Homa-Hills Geothermal Prospect, Kenya
(2013)In order to fully assess the potential of Homa Hills Geothermal prospect, the heat source which is one of the main features of a geothermal system had to be located based on its perturbation on the gravity ... -
Effect of Human Activities and Seasonal Variation on Water Quality of Nkenye (Chikuu) Stream in Chuka, Kenya
(2013-01)Composite water and sediment samples were taken from Nkenye stream at five different sampling stations during wet and dry seasons. Water quality parameters were analyzed using standard methods to ascertain ... -
Price and Volumes Reaction to Annual Earnings Announcement: A Case of the Nairobi Securities Exchange
(2013-02)Modern corporate organizations listed in the security markets periodically communicate their financial performance to stakeholders through earnings announcements. Efficient markets immediately absorb and reflect the new ... -
Conjecture of banach space operator ideals in nuclear spaces
(2013-06)We apply the notion of Banach space operator ideals in nuclear spaces through topological vector spaces. The motivation for this study came from attempts to generalize the structure of nuclear spaces as a result of nuclear ... -
On Almost Similarity Operator Equivalence Relation
(2013-06)We consider the almost similarity property which is a new class in operator theory and was first introduced by A. A. S. Jibril. We establish that almost similarity is an equivalence relation. Some results on almost similarity ... -
Assessment of ICT Infrastructure on ICT Adoption in Educational Institutions
(2013-06)Globalization and liberalization have facilitated intensive business competition which in turn has increased the need for adoption of new technologies to increase the efficiency in service delivery. ICT has wide application ... -
Nitrogen Fixation by Natural Populations of Acacia Senegal in the Drylands of Kenya Using 15N Natural Abundance
(Taylor and Francis Online, 2013-06-24)Nitrogen (N) fixation was estimated for three Acacia senegal (L.) (A. senegal) Willd. varieties (A. senegal var. senegal, kerensis, and leiorhachis) growing naturally in different sites in the dryland areas of Kenya. The ... -
Automation of pressure and temperature measurements in vacuum deposition systems
(2013-08)This paper describes a simple automated instrumentation and measurement system that is designed to offer a more reliable and fast method of measuring temperature and pressure, in thin film deposition systems. ... -
Determination Of The Density And The Damping Properties Of Polyethylene (Pe) And Polylactic (Pla) Films Using Dma
(2013-08)Damping which is an effect that tends to reduce the amplitude of oscillations in an oscillatory system is significant in components under high dynamic loads especially in general mechanical engineering. In this study, ... -
``Transitivity Action of An(n=5,6,7,8) On Unordered and Ordered Pairs’’
(2013-09)In this paper, we study some transitivity action properties of the alternating group 𝐴𝑛(𝑛=5,6,7 ,8) acting on unordered and ordered pairs from the set 𝑋𝑋 = {1,2,…,𝑛𝑛} through determination of the number of disjoint ... -
Rapid, Economical and selective Compexometric Determination of Iron (III) in its synthetic alloys using 3 hydroxy-3- phynyl-1-(2,4,6-tribromophynyl)
(2013-09)The present study describes a simple, selective, rapid and economical method for the determination of iron (III) in its synthetic alloys using 3-hydroxy -3- phenyl-1- (2,4,6- tribro mophenyl) triazene as ... -
Suborbital Graphs and their properties for unordered pairs in An(n=5,6,7,8) through rank and subdegrees determination’’
(2013-12-18)In this paper, through computation of the rank and subdegrees of alternating group ( =5,6,7) on unordered triples we construct the suborbital graphs corresponding to the suborbits of these triples. When ( ≥ 5) acts on ... -
Reflectance, Transmittance and Absorptance of HDPE, LDPE, Glass and Sand Layer Used in a SAH
(2014)The total Infra-red (IR) transmission of polymer films is a very important property in engineering, which determines their suitability for a specific application at a given temperature level. Aiming to investigate the ... -
2D-Euler Deconvolution and Forward Modeling of Gravity Data of Homa-Hills Geothermal Prospect, Kenya
(2014)In order to fully assess the potential of Homa Hills Geothermal prospect, the heat source which is one of the main features of a geothermal system had to be located based on its perturbation on the gravity field. Ground ... -
Parasites of Commercially Important Fish from Lake Naivasha, Rift Valley, Kenya.
(springer, 2014-01)In Lake Naivasha, the common carp Cyprinus carpio L. 1758 was accidentally introduced from fish farms adjacent to River Malewa in 1999 and now forms the bulk of the total fish caught. Since its introduction, no study has ... -
