Comparative responses in plain black tea quality parameters of different tea clones to fermentation temperature and duration
(Elsevier, 2001-02-01)The amounts of black tea theaflavins, brightness, and sensory evaluations varied with clones in the order clone 6/8>SC12/28>S15/10, while thearubigins and total colour changed in the reverse order. The rates of change of ... -
Effects of Geographical Area of Production on the Composition of the Volatile Flavour Compounds in Kenyan Clonal Black CTC Teas
(Cambridge University Press, 1988-04)The contents of the volatile flavour compounds and the flavour index of black teas vary with localities. The magnitude and order of the variations are clonally dependent, the relative performance of clones varying with ... -
Optimising fermentation time in black tea manufacture
(Elsevier, 1986)A comparative study using in-line theaflavins analysis (ILTF), theaflavins of made-tea analysis (TFMT) and tasters' evaluations, to optimise fermentation during tea manufacture, was carried out. All methods obeyed a quadratic ... -
Comparison of gas chromatographic volatile profiling methods for assessing the flavour quality of kenyan black teas
(John Wiley & Sons, Ltd, 1992-01-01)A comparison is made of the various ratios used to quantify black tea aroma such as the ratio of the sum of gas chromatographic peak areas of compounds eluting before linalool (3,7-dimethyl-1,6-0ctadien-3-01) to those ... -
Assessment of road contractors’ eprocurement adoption barriers in Kenya rural roads authority, Kenya
(International Journal of Development and Sustainability, Volume 7 Number 4 (2018): Pages 1286-1298, 2018-05)The study assessed road contractors’ e-procurement adoption barriers in KeRRA Busia guided by resource based and legitimacy theories on a descriptive design. A sample size of 323 out of 1667 contractors was drawn using ... -
Selective Blockade of Trypanosomatid Protein Synthesis by a Recombinant Antibody Anti-Trypanosoma cruzi P2β Protein
(Public Library of Science, 2012-05-03)The ribosomal P proteins are located on the stalk of the ribosomal large subunit and play a critical role during the elongation step of protein synthesis. The single chain recombinant antibody C5 (scFv C5) directed against ... -
Proteins Associated with SF3a60 in T. brucei
(Public Library of Science, 2014-03-20)Trypanosoma brucei relies on Spliced leader trans splicing to generate functional messenger RNAs. Trans splicing joins the specialized SL exon from the SL RNA to pre-mRNAs and is mediated by the trans-spliceosome, which ... -
Influence of Students’ Attitude Towards Physical Punishment Ban on Student Discipline in Public Secondary Schools In Ugenya, Gem and Siaya Sub-Counties, Kenya
(International Journal of Innovative Research and Advanced Studies (IJIRAS), 2018-05-05)The study was undertaken in Ugenya, Gem and Siaya sub-Counties within Siaya County in Kenya. This study sought to investigate the influence of students’ attitude to physical punishment ban on the level of student discipline ... -
Depletion of trypanosome CTR9 leads to gene expression defects
(Public Library of Science, 2012-04-20)The Paf complex of Opisthokonts and plants contains at least five subunits: Paf1, Cdc73, Rtf1, Ctr9, and Leo1. Mutations in, or loss of Paf complex subunits have been shown to cause defects in histone modification, mRNA ... -
Functional characterization and protein–protein interactions of trypanosome splicing factors U2AF35, U2AF65 and SF1
(Elsevier, 2009-04-01)Early in the assembly of the spliceosome of eukaryotes the branch-point binding protein (BBP, also called SF1) recognizes the branch point sequence, whereas the heterodimer U2AF consisting of a 65 and a 35 kDa subunit, ... -
Protein–protein interaction map of the Trypanosoma cruzi ribosomal P protein complex
(Elsevier, 2005-09-12)The large subunit of the eukaryotic ribosome possesses a long and protruding stalk formed by the ribosomal P proteins. Four out of five ribosomal P proteins of Trypanosoma cruzi, TcP0, TcP1α, TcP2α, and TcP2β had been ... -
Changes in theaflavin composition and astringency during black tea fermentation
(Elsevier, 1994-01-01)Both theaflavins and sensory evaluations vary in a quadratic manner with fermentation duration in the process of black tea manufacture. The rate of formation of total (Flavognost) theaflavins varies with clones, and within ... -
Clonal variation in the individual theaflavin levels and their impact on astringency and sensory evaluations
(Elsevier, 1995-01-01)Clonal variation in the individual theaflavin levels and their impact on astringency and sensory evaluations -
Tea Aroma
(Chapman and Hall, London, 1992)Tea is manufactured by a variety of processes producing a range of beverages from green, non-fermented tea through to black, fermented tea. The consumer acceptability of these beverages is largely dependent on the flavor ... -
The changes in black tea quality due to variations of plucking standard and fermentation time
(Elsevier, 1998-04)Catechin levels in green leaf, total theaflavins, brightness, thearubigins, colour, flavour index and sensory evaluation decrease with coarse plucking standard in clone 6/8. The sum of Group I volatile flavour compounds ... -
Determinants of Households’ Market Participation around Community Milk Cooling Plants, Western Kenya
(2018-02-09)Market participation in sub-Saharan Africa has been assessed mainly based on already producing households by looking at whether they sold or not, and if they sold, what quantities. The objective of this study was to determine ... -
Evaluation of Fish Processing and Preservation Systems along the Shores of Lake Victoria towards Enhancement of Sun Drying Technology
(Scientific & Academic Publishing, 2017)Fish products play an important role in human diet due to peculiar lipid composition. In Kenya Lake Victoria is an important source of fresh water fish contributing over 90% of the national fish production. The Lake Victoria ... -
Single and competitive removal of sulfachloropyridazine and sulfadimethoxine onto natural kaolinite clay: kinetics, isotherms and thermodynamics studies
(2017)In this study, local untreated clay was tested for its ability to adsorb sulfonamides, namely, sulfachloropyridazine (SCP) and sulfadimethoxine (SDM) from synthetic wastewater by batch equilibration. The time-dependent ... -
