brassica juncea l. is an important oilseed crop which occupies premier position in indian agriculture. developing high yielding genotypes has been a major breeding objective in indian mustard. present study was conducted at directorate of rapeseed-mustard research, india, during 2010-2013 to determine general combining ability (gca) and specific combining ability (sca) of parental lines and bet...

Gene regulatory networks depict the interactions among genes in the cell and construction of networks is important in uncovering the underlying biological process of living organisms. In this paper, a non-linear differential equation model is used for gene regulatory network reconstruction and time-series prediction. A new model, called additive expression tree (AET) model is proposed to encode...

In bread wheat (Triticum aestivum L.), crop height is an important determinant of agronomic performance. To map QTLs with additive effects and additive×additive epistatic interactions, 148 recombinant inbred lines and their parents, (‘YecoraRojo’ and Iranian landrace (No. #49)) were evaluated under normal and water deficit conditions. The experiments were carried out on research farms of Mahaba...

Genes that influence a phenotype earlier in life may differ from those influencing the same phenotype later, particularly during significant development periods such as puberty, when it is known that new genetic and environmental influences may become important. In the present study, body mass index (BMI) data were collected from 470 monozygotic twin pairs and 673 dizygotic twin pairs longitudi...

The enormous variety of substances which may be added to forage in order to manipulate and improve the ensilage process presents an empirical, combinatorial optimization problem of great complexity. To investigate the utility of genetic algorithms for designing effective silage additive combinations, a series of small-scale proof of principle silage experiments were performed with fresh ryegras...

OBJECTIVE To analyze the association between concentrations of air pollutants and admissions for respiratory causes in children. METHODS Ecological time series study. Daily figures for hospital admissions of children aged < 6, and daily concentrations of air pollutants (PM10, SO2, NO2, O3 and CO) were analyzed in the Região da Grande Vitória, ES, Southeastern Brazil, from January 2005 to Decemb...

A thermoset PMS (Polyvinyl modified silicone) type polymer additive effect on load bearing capacities of cement grouted rock bolt specimens exposed to thermal cycles was investigated with a series experimental studies. The used in this study liquid phase while adding into the fresh mix and started solidify by polymerization after being mixed well grout. silicone based product selected use becau...

The application of quantitative genetics in plant and animal breeding has largely focused on additive models, which may also capture dominance and epistatic effects. Partitioning genetic variance into its additive and nonadditive components using pedigree-based models (P-genomic best linear unbiased predictor) (P-BLUP) is difficult with most commonly available family structures. However, the av...
