A prospective cohort study was conducted in five purposively-sampled agro-ecological zone (AEZ)-grazing system strata in Murang'a District, Kenya, between March 1995 and June 1996. The study strata were selected based on a preliminary characterization study to represent the widest range of risks to East Coast fever (ECF) in the District and included zero-grazing and open-grazing farms. In total...

This study is aimed to develop agroecological zone model (AEZ) integrated with the evaluation of land suitability in order to attain the food tenacity in Boyolali County, Central Java, Indonesia. This model is established through five steps. First, it is stocktaking and identifying biophysical land characteristic. The second step is compiling map of suitability of land commodities. The third is...

Field experiment on Tomato-Okra-Indian spinach cropping pattern was conducted at a farmer’s homestead of Tangail (AEZ 8) during 2007-08 and 2008-09 to find out a suitable combination of chemical fertilizers and organic manure for sustainable crop yield. There were 5 treatments comprising different percentages of the recommended chemical fertilizers (RCF) with two levels (0 and 5 t/ha) for tomat...

We discuss in detail the dynamics of maps z 7→ aez + be −z for which both critical orbits are strictly preperiodic. The points which converge to ∞ under iteration contain a set R consisting of uncountably many curves called “rays”, each connecting ∞ to a well-defined “landing point” in C, so that every point in C is either on a unique ray or the landing point of finitely many rays. The key feat...

This paper reviews an analysis of land use change impacts of expanded biofuel production with GTAP-BIO computable general equilibrium (CGE) model. It describes the treatment of energy substitution, the role of biofuel by-products, specification of bilateral trade, the determination of land cover changes in response to increased biofuel feedstock production, and changes in crop yields – both at ...

Epigenetics is the branch of biology that studies effects environment on genetics and vice versa. It connecting link between genotype phenotype an individual, can be widely influenced by nutrition availability certain essential micronutrients, in this review, zinc. Although a trace element, zinc to body as core component more than 300 proteins enzymes, which when functioning normally impart str...

Acrodermatitis enteropathica (AE) is an uncommon autosomal recessive genetic disorder of zinc malabsorption. The acquired form may be associated with inadequate intake, impaired absorption, and increased excretion of zinc. Those afflicted present with diarrhea, stomatitis, psychiatric symptoms, non-scarring alopecia, and nail dystrophy accompanied by erythematous which appears as scaly patches ...
