Since Drosophila melanogaster colonized Europe from tropical Africa 10 to 15 thousand years ago, it is expected that adaptation has played a major role in this species in recent times. A previously conducted multilocus scan of noncoding DNA sequences on the X chromosome in an ancestral and a derived population of D. melanogaster revealed that some loci have been affected by directional selectio...

AIM The present study was conducted to evaluate the dietary addition of Emblica officinalis (Amla) fruit powder as a growth promoter in commercial broiler chickens. MATERIALS AND METHODS An experiment was conducted on 135 commercial broiler chicks (Ven-Cobb 400 strain) divided into three groups with three replicates of 15 chicks each. Three treatment groups were as follows - T1: Basal diet as...

poly(vinyl acetate) is synthesized via solution polymerization, and then it is converted to poly(vinyl alcohol) by alkaline alcoholysis. the aim of the work study was to investigate statistically the  influence of reaction variables in vinyl acetate polymerization, the conversion of this monomer to polymer, degree of branching of acetyl group in poly(vinyl acetate), as well as the molecular wei...

A study was undertaken to analyses the heritability, correlation and path co-efficient for growth and fruit characters in twenty ber (Ziziphus mauritiana Lam) genotypes grown at Fruit Research Farm under Horticulture Research Centre, BARI during January to June 2006. The highest range of variation was recorded in fruit weight (6.63-44.72 g), followed by yield per plant (14.88 64.99 kg), stone w...

BACKGROUND AND AIMS It is widely accepted that fruit-set in plants is related to source-sink ratio. Despite its critical importance to yield, prediction of fruit-set remains an ongoing problem in crop models. Functional-structural plant models are potentially able to simulate organ-level plasticity of plants. To predict fruit-set, the quantitative link between source-sink ratio and fruit-set pr...
