The occurrence of the brine shrimp, Artemia franciscana (Kellog 1906) in Kenya and the potential economic impacts among Kenyan coastal communities
(Kenya Marine and Fisheries Research Institute, Kegati Aquaculture Research Station, 2014)The occurrence of Artemia populations in Kenyan coast is a noble happening. However, much information is lacking concerning its exploitation for Larviculture. This paper reviews inoculation of Artemia in the Kenyan coast ... -
Occurrence of Trypanosoma in Nile tilapia in Lake Victoria, Kenya
(Sokoine university of agriculture, 2008)Oreochromis niloticus (Nile tilapia) and Lates niloticus (Nile perch) are the most abundant species and economically important fish in Lake Victoria. The former are omnivores and the latter are carnivorous. The carrier ... -
Occurrence, genetic relatedness and effects of diplostomum(digenea: diplostomidae) species in oreochromis niloticus L. and distribution among Vector snails in Kibos area
(Maseno University, 2013)Diplostomum species metacercariae, are trematodes that pose economic threat to aquaculture globally. Despite their diversity, species identification is difficult owing to their striking morphological similarities. Poor ... -

Olikoye Ransome-Kuti: a treasured advocate for primary health care and a pioneer of good health governance
(African Journal of Reproductive Health, 2023-05-31)Given the phenomenal contributions he made to primary health care worldwide, and to the promotion of sexual and reproductive health care in the African region, the African Journal of Reproductive Health (AJRH) has ... -
On a complex spacetime frame: new foundation for physics and mathematics
(Research gate, 2016)This paper provides a derivation of a unit vector specifying the temporal axis of four-dimensional space-time frame as an imaginary axis in the direction of light or general wave propagation. The basic elements of the ... -
On a generalized q-numerical Range
(Maseno university, 2008)We 'consider numerical ranges of a bounded linear operator on complex Hilbert spaces. Many properties of the classical numerical range are known. We investigate the properties of the q-numerical range in relation to ... -
On atomic state purity operator, degree of state purity and concurrence in the JC and anti-JC models
(arxiv.org, 2022)The state of an atom in a bipartite qubit, Jaynes-Cummings (JC) or anti-Jaynes-Cummings (aJC) interaction is described by a reduced density operator. The purity of the state has been measured by taking the trace of the ... -
On atomic state purity operator, degree of state purity and concurrence in the JC and anti-JC models
(Maseno University, 2020)The state of an atom in a bipartite qubit, Jaynes-Cummings (JC) or anti-Jaynes-Cummings (aJC) interaction is described by a reduced density operator. The purity of the state has been measured by taking the trace of the ... -
On Characterization of Scalar Operators via Semigroup and the Associated Generators
(Hikari Ltd, 2016)In this paper, we characterize the scalar operators by using the semigroup theory and the corresponding generators of (α, α + 1) type R operators. In particular, we show that if a densely defined operator H generates a ... -
On completely bounded Operators
(2010)Calculating norms of matrices when the entries are not constants is the first problem tackled in this thesis. We have considered the space of matrices with entries from the algebra of bounded linear operators and ... -
On completely positive maps
(Maseno University, 2015)Completely positive maps is an important field due to its significance, application and mathematics itself. While discussing the properties of the positive maps, researchers have questioned whether the properties of the ... -
On Generalized Fibonacci Numbers
(Communications in Advanced Mathematical Sciences, 2020)Fibonacci numbers and their polynomials have been generalized mainly by two ways: by maintaining the recurrence relation and varying the initial conditions, and by varying the recurrence relation and maintaining the initial ... -
On Joint Essential Numerical Ranges
(Maseno University, 2013)The concept of numerical range on a Hilbert space was first introduced by O. Toeplitz in 1918 for matrices. This notion was independently ex tended by G. Lumer and F. Bauer in the sixties on finite dimensional Banach ... -
On necessary Conditions for scalars
(Hikari Ltd, 2014)In this paper, we give a characterization of scalar operators. In particular we show that a densely defined closed linear operator H acting on a reflexive Banach space X is scalar if it is of (0, 1) type R and f (H)≤ f∞ ... -
On Noncrossing and Plane Tree-Like Structures
(Communications in Advanced Mathematical Sciences, 2021)Mathematical trees are connected graphs without cycles, loops and multiple edges. Various trees such as Cayley trees, plane trees, binary trees, d-ary trees, noncrossing trees among others have been studied extensively. ... -
On norms of a derivation
(Maseno university, 2010)The study of derivations still remains an area of interest to mathematicians today. Of special attention has been the study of norms of inner derivations. Most of the work in this area is based on Stampfli's result of ... -
On norms of elementary operators
(2009)The study of elementary operators has been of great interest to many mathematicians for the past two decades. Of special interest has been to determine the norms of these operators. The norm problem for elementary operators ...
