Nematodes and fungi associated with apple replant disorder in sampled New York State orchards.
(2014)The factors associated with unthrifty growth of apple are not fully determined, resulting i n inadequate diagnosis of apple replant disorder (ARD). The present study isolated and identified nematodes and fungi from ARD ... -
Nephrotoxicity effects of Khat (Catha edulis) on mice when administered orally
(2017-03)Renal problems are currently on increase worldwide. Some factors suspected to be the cause of the renal problems are drug abuse. Hence, this study investigated possible renal toxicity effect of ... -
NEW METALLOCHROMIC INDICATORS FOR COMPLEXOMETRIC TITRATION OF COPPER (II) IN PRESENCE OF INTERFERING SPECIES
(Life Science Informatics Publications, 2020-09)Six hydroxytriazenes has been introduced as a metallochromic indicator in the complexometric titration with EDTA and applied successfully to the titration of copper (II). A direct method of titration of Cu (II) with EDTA ... -
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 ... -
Nonthermal synthesis of three-dimensional metal oxide structures under continuous-flow conditions and their catalytic applications
(American Chemical Society, 2011-10-25)Continuous-flow synthesis of one-dimensional (1D) metal oxide nanostructures and/or their integration into hierarchical structures under nonthermal conditions is still a challenge. In this work, a nonthermal, continuous-flow ... -
Norm Estimates for Norm-attainable Elementary Operators
(HIKARI ltd, 2018-03-20)In this paper we estimates the norms of norm-attainable elementary operators: inner derivations, generalized derivation, basic elementary operator and Jordan elementary operator. -
Norm- Attainability of Generalized Finite Operators on C*- Algebra
(Modern Scientific Press Company, 2022)Norm -attainability of elementary operators on Hilbert and Banach spaces have been Characterized by many mathematicians. However, there is little information on Normattainability of generalized finite operators on C*-algebra. ... -
A note on quasi-similarity of operators in Hilbert spaces
(2015-01)In this paper we introduce the notion of Quasi-similarity of bounded linear operators in Hilbert Spaces. We do so by defining a quasi-affinity from one Hilbert Space H to K. Some results on quasi-affinities are also ... -
A NOTE ON QUASI-SIMILARITY OF OPERATORS IN HILBERT SPACES
(International Journal of Mathematical Archive, 2015-07-23)In this paper we introduce the notion of Quasi-similarity of bounded linear operators in Hilbert Spaces. We do so by defining a quasi- affinity from one Hilbert Space H to K. Some results on quasi- affinities are also ... -
A novel mutation in TFL1 homolog sustaining determinate growth in cucumber (Cucumis sativus L.)
(Springer-Verlag GmbH Germany, part of Springer Nature, 2020)Determinate and indeterminate growth habits of cucumber can affect plant architecture and crop yield. The TER MINAL FLOWER 1 (TFL1) controls determinate/indeterminate growth in Arabidopsis. In this study, a novel mutation ... -
Novel Sources of Witchweed (Striga) Resistance from Wild Sorghum Accessions
(2017-02)Sorghum is a major food staple in sub-Saharan Africa (SSA), but its production is constrained by the parasitic plant Striga that attaches to the roots of many cereals crops and causes severe stunting and loss of yield. ... -
Nurturing the Industrial Economy Through Enterprise Education: The Case of Kenyan Universities
(IGI Global, 2021)In recognition of the importance of ensuring adequate supply of highly educated workers, many countries have expanded and reformed their educational programmes. Despite this, many manufacturing companies are struggling ... -
Nutrient digestibility in diets containing low-phytate barley, low-phytate field pea and normal phytate field pea, and the effects of microbial phytase on energy and nutrient digestibility in the low and normal-phytate field pea fed to pigs
(Elsevier, 2015-05)Five ileal cannulated barrows (43.6 ± 1.3 kg BW) were used in a 5 × 5 Latin square design experiment to determine the apparent (AID) and standardized (SID) ileal digestibility of N and amino acids (AA) in low-phytate field ... -
Nutrient management options for enhancing productivity and profitability of conservation agriculture under on-farm conditions in central highlands of Kenya
(AIMS Agriculture and Food, 2020)Decline in soil fertility is one of the major constraints to sustainable crop production and profitability. To meet the increasing demand for the growing population the issue of low soil fertility needs to be addressed. ... -
Nutritional and microbial quality of extruded fish feeds containing black soldier fly (Hermetia illucens L) larvae meal as a replacement for fish meal for Nile Tilapia (Oreochromis niloticus) and African sharptooth catfish (Clarius gariepinus)
(Taylor & Francis, 2021-05-24)The black soldier fly (Hermetia illucens L.) is a potential substitute of fish meal in feeds. However, information on the nutrition and safety of these feeds is inadequate. This study examined the quality of fish feed ... -
