abstractbackground and objectives: black mustard (brassica nigra (l.) koch) is an annual plant belongs brassicaceae. it has a variety of uses in traditional medicine for rheumatic and neurological pain. growth and development and production of medicinal plants, like other plants is influenced by genetic and environmental factors. select the most appropriate planting date and the most favorable ...

In this thesis, the application of numerical techniques to electromagnetic problems in microelectronic and radar imaging systems are investigated. In particular the following problems are studied: (1) Dielectric rib waveguide discontinuities are analyzed with the Finite Difference Time Domain (FDTD) method. The application of Berenger's Perfectly Matched Layer to multi-layered dielectrics is an...

26 Background: Distance from home to school is an important influence on the decision 27 to use active transport (AT); however, ecological perspectives would suggest this relationship 28 may be moderated by individual, interpersonal, and environmental factors. This study 29 investigates whether (i) gender, (ii) biological maturation, (iii) perceived family support for 30 physical activity (PA),...

Subjects performed maximum vertical jumps on a force platform to reveal whether resulting force-time curves could identify characteristics of good performances. Instantaneous power-time curves were also derived from the force-time curves. Eighteen temporal and kinetic variables were calculated from the forceand power-time curves and were compared with the takeoff velocities and maximum heights ...

We have investigated the performance of popular density functionals that include van der Waals interactions for the experimentally well-characterized problem of ethene (C(2)H(4)) adsorbed on the low-index surfaces of copper. This set of functionals does not only include three van der Waals density functionals-vdwDF-PBE, vdwDF-revPBE and optB86b-vdwDF-and two dispersion-corrected functionals-Gri...

We construct genomic predictors for heritable and extremely complex human quantitative traits (height, heel bone density, and educational attainment) using modern methods in high dimensional statistics (i.e., machine learning). Replication tests show that these predictors capture, respectively, ∼40, 20, and 9 percent of total variance for the three traits. For example, predicted heights correla...

Hip heights were measured on 286 three-breed cross calves at weaning, yearling and slaughter time and on 199 Angus calves at yearling time to study the relationships of hip height with growth, feedlot performance and carcass traits when cattle are slaughtered at an anticipated grade of low choice. Correlations between hip height and weaning, yearling and slaughter weight averaged .56. Yearling ...

This study provides the first in depth assessment of Sea Otter haul-out patterns in Elkhorn Slough, California and their relationship to environmental variables. Seasonal and daily water and air temperature fluctuations are a good predictor of Sea Otter haul-out patterns but are affected by the availability of haul-out sites at different tide levels. The cost effectiveness of this choice may be...

black saxaul (haloxylon aphyllum) is one of the best options for rehabilitating drought affected desert lands. the species is remarkably adapted to the central dry environment ofiran and a major source of raising pasture productivity of the areas. progenies of 25 randomly selected black saxaul trees from four populations of the species were studied in a randomized complete block design with thr...
