Effects of pH and metal ions on oxytetracycline sorption to maize-straw-derived biochar
(Elsevier, 2013-05-30)
Biochars produced from biomass residues have been recognized as effective sorbents to
hydrophobic compounds, but knowledge on sorption of antibiotics to biochar and its
mechanisms are still inadequate. Sorption of ...
Enhanced degradation of 14 C-HCB in two tropical clay soils using multiple anaerobic–aerobic cycles
(2013-02-28)
The aim of the study was to induce and enhance the degradation of hexachlorobenzene
(HCB), a highly-chlorinated persistent organic pollutant, in two ecologically different tropical
soils: a paddy soil (PS) and a non-paddy ...
Immobilization of chlorobenzenes in soil using wheat straw biochar
(American Chemical Society, 2013-04-25)
Biochar has shown great potential for immobilizing organic contaminants in soil. In this
study, pentachlorobenzene (PeCB), 1, 2, 4, 5-tetrachlorobenzene (1, 2, 4, 5-TeCB), and 1, 2,
4-trichlorobenzene (1, 2, 4-TCB) ...
Antinociceptive and antiplasmodial activities of cassane furanoditerpenes from Caesalpinia volkensii H. root bark
(Elsevier, 2012-01-01)
The chloroform and ethyl acetate extract (100mg/kg) of Caesalpinia volkensii H. exhibited
significant (P≤ 0.05) antinociceptive activities using hot plate and writhing tests in mice
while the later showed antiplasmodial ...
Influence of region of production on relative clonal plain tea quality parameters in Kenya
(Elsevier, 2010-04-01)
Tea is grown in diverse regions with varying climates. Growers seek high-yielding and
superior quality cultivars to improve profitability of the enterprise. A superior quality genotype
in one location is assumed to ...
The influence of geographical area of production and nitrogenous fertiliser on yields and quality parameters of clonal tea
(2010-04-01)
Variations in requirements for tea production in Kenya and factors controlling
growth and production of secondary metabolites responsible for the quality parameters are
indicative of the need for non-uniform recommendations. ...
Spatial distribution and habitat characterization of mosquito species during the dry season along the Mara River and its tributaries, in Kenya and Tanzania
(Bio Med Central, 2018-12)
Vector-borne diseases are increasingly becoming a major health problem among
communities living along the major rivers of Africa. Although larger water bodies such as
lakes and dams have been extensively researched, ...
Effects of land use change on land degradation reflected by soil properties along Mara River, Kenya and Tanzania
(Scientific Research Publishing, 2015-01-01)
Human-induced changes to natural landscapes have been identified as some of
the greatest threats to freshwater resources. The change from natural forest cover to
agricultural and pastoral activities is rampant especially ...
Triterpenes from Elaeodendron schweinfurthianum and Their Antimicrobial Activities against Crop Pathogens
(Scientific & Academic Publishing, 2017-01-26)
Phytochemical evaluation of Elaeodendron schweinfurthianum (Loes) extracts led to the
isolation of nine compounds which were identified as 3-oxofriedelane (1), 3α-
hydroxyfriedelane (2), 3-oxo-29-hydroxyfriedelane (3), ...
Variation in indoor levels of polycyclic aromatic hydrocarbons from burning various biomass types in the traditional grass-roofed households in Western Kenya
(Elsevier, 2011-07-31)
Biomass burning as fuel in the traditional grass-roofed rural households of Western
Province of Kenya in open fire places, in poorly ventilated conditions, lead to accumulation
of soot under the roofs. This study ...
