Tunneling and nonadiabatic transition are the most important quantum mechanical effects in chemical dynamics. They are important not only for understanding the dynamics properly, but also for controlling molecular functions. The Zhu-Nakamura (ZN) theory can be combined with the quasi-classical trajectory method and with the IVR (Initial Value Representation)-type semiclassical theory to deal wi...

the search for alternative ways of controlling sericultural pests has led to the investigation of plant sources for naturally occurring compounds which may have insect growth regulatory, feeding deterrency, repellency and confusantcy characteristics. more than 2000 species of the families asteraceae, fabaceae and euphorbiaceae are known that possess some insecticidal activity. plants with insec...

This study was aimed to gain knowledge on the ontogeny of digestive enzymes in common carp larvae at the governmental Warm water Fish Aquaculture Center of Shahid Rajaee in Sari, Mazandaran, Iran. The ontogenetic development of pancreatic (trypsin, chymotrypsin, lipase and α-amylase) and intestinal (alkaline phosphatase and aminopeptidase-N) enzymes were assessed in common carp larvae from firs...

The effects of grain and carbohydrase enzyme supplementation were investigated on digestive physiology of chickens. A total of 625 one-day-old chicks (Ross 308) were randomly assigned to five treatments in a completely randomized design. Treatments included two different types of grains (wheat, and barley) with or without a multi-carbohydrase supplement. A corn-based diet was also considered to...

1. Aims This section sets out to answer the second aim of this study, namely:-ii) To determine qualitatively and quantitatively the food eaten by that population,. The information presented in this section (unless otherwise stated) has been obtained from the Study Block (see Section II) by the methods described below. The previous section, which considered the population aspects, formed an esse...

the objective of this study was to evaluate the effect of dietary supplements with lead acetate and aluminosilicates (atn) on antioxidative enzyme activities and lipid peroxidation of the heart and skeletal muscle tissues of broiler chickens. broilers were allotted to four diets including the control group, the pb group, the aluminosilicate-atn (antitoxic nutrient) group and the pb+atn group, i...

Purpose Frequent desaturation due to immature incoordination of suck-swallow-breathing in preterm infants can influence multiple organs such as the heart, lungs, and brain, which can then affect growth and development. Most notably in preterm infants, feeding desaturation may even affect pulmonary function during gavage feeding. Because respiratory muscle activities may reflect the work require...

A comprehensive study of Schottky barrier MOSFET (SBMOSFET) scaling issue is performed to determine the role of wafer orientation and structural parameters on the performance of this device within Non-equilibrium Green's Function formalism. Quantum confinement increases the effective Schottky barrier height (SBH). (100) orientation provides lower effective Schottky barrier height in compa...
