Toward a size scale-up cold sintering process at reduced uniaxial pressure
(The American Ceramic Society, 2019)Cold sintering is a low-temperature powder process methodology that enables the densification of ceramics and ceramic-based composites at significantly reduced times and temperatures. Although the general notion of ... -
Comparison of severity of Phytophthora colocasiae (taro leaf blight) disease on in-vivo and in-vitro Pacific-Caribbean and Kenyan taro (Colocasiae esculenta) grown in Kakamega county (Kenya)
(GSC Biological and Pharmaceutical Sciences, 2019)Taro (Colocasiae esculenta) is an important tuber crop of Kakamega - Kenya. It is nutritionally very rich. Taro leaf blight (TLB) is the most devastating pathogen for its production worldwide and current management ... -
Allelopathic Effects ofEucalyptus Saligna on Germination Growth and Development of Vigna Unguiculata L.Walp
(IOSR Journal of Environmental Science, Toxicology and Food Technology (IOSR-JESTFT), 2018)Allelopathic effects of Eucalyptus are widely reported and considered the major factor limiting the establishment of native species in eucalyptus forest.

Adaptive Strategies of the Centrospermeae Species with Different Photosynthetic Systems in the Semi-Arid and Saline Areas in Mt. Kulal - Mt. Elgon Habitats in Kenya.
(Quest Journals, 2018)Centrospermeae species were collected at different sites along gradient of altitude and aridity in the semi-arid, saline and arid habitats in western region of Kenya. δ13C values and Kranz leaf anatomy were used to examine ... -
Molecular diversity, geographic distribution and host range of monocot-infecting mastreviruses in Africa and surrounding islands
(Elsevier, 2017)Maize streak virus (MSV), an important pathogen of maize in Africa, is the most extensively studied member of the Mastrevirus genus in the family Geminiviridae. Comparatively little is known about other monocot-infecting ... -
Influence of Climatic Factors on the Δ13c Values of the C3, C4 And CAM Dicot Species (Vegetation) of the Centrospermeaealong Altitudinal Gradient in western Region of Kenya
(Research Gate, 2017)Species of the Centrospermeae occurring at different altitudes were analyzed for δ13C values and assigned for graphical representation. The aridity of the study area was evident as defined using the Klimadiagramm. Climatic ... -
A Critical Review of the Female Gametophyte in the Podostemaceae - Past, Present and Future Studies
(Research Gate, 2017)Anoverview of the habit and habitat of Podostemaceae is briefly discussed. Then,the paper attempts to review the past and present female gametophyte studies in the Podostemaceae. It trace the course and major achievements ... -
Ecological implications of the ẟ13C values of plant species growing in natural environment, greenhouse and plant respired carbon dioxide (captured as carbonate).
(Research Gate, 2017)ẟ13C values have been used to differentiate the C3 plant species from the C4 species. Light isotope (12C) is favoured against the heavier isotope (13C) during the carbon fractionation in plant species. The ẟ13C valuesof ... -
