Previous theoretical studies (Gross and Seybold, Int J Quantum Chem 2000, 80, 1107; Gross et al., J Org Chem 2001, 66, 6919; Gross et al., Int J Quantum Chem 2002, 90, 445) demonstrated that variations in several quantum chemical charge and energy indices for substituted anilines were strongly correlated with the experimentally observed pKa variations of these compounds. The present study exami...

Through a suitable expansion of the Gross-Pitaevskii equation near the classical turning point, we obtain an explicit solution for the order parameter at the boundary of a trapped Bose gas interacting with repulsive forces. The kinetic energy of the system, in terms of the classical radius R and of the harmonic oscillator length a HO , follows the law Ekin/N ∝ R [log(R/a HO ) + const.], approac...

This work is devoted to the analysis of the quantum drift-diffusion model derived by Degond et al in [6]. The model is obtained as the diffusive limit of the quantum Liouville-BGK equation, where the collision term is defined after a local quantum statistical equilibrium. The corner stone of the model is the closure relation between the density and the current, which is nonlinear and nonlocal, ...

A model predicting the nutritional cost of measles has been based on data from a study of energy balance in Kenyan children during and after measles. The energy shortfall, consequent upon a reduction in energy intake and a sustained level of energy expenditure, is met by tissue catabolism. The magnitude of resulting weight loss will be greater in lean than in plump children. During recovery, th...

In this paper, we present an alternative derivation of the entropy production in turbulent flows, based on a formal analogy with the kinetic theory of rarefied gas. This analogy allows for proving that the celebrated k − e model for turbulent flows is nothing more than a set of coupled BGK (Bhatnagar–Gross–Krook)-like equations with a proper forcing. This opens a novel perspective on this model...

The structure of energy-use in Indian agriculture has changed substantially, with a significant shift from the animal and human power towards machines, electricity and diesel. The total commercial energy input in Indian agriculture has increased from 425.4 × 109 Mega Joules in 1980-81 to 2592.8 × 109 Mega Joules in 2006-07. This shift, coupled with increasing commercialization and diversificati...

Ram lambs, wethers and wethers implanted with Silastic capsules containing crystalline testosterone were placed on test at 14.9 +/- 1.1 kg and evaluated for differences in growth, performance, carcass characteristics and composition. Silastic implants that were able to maintain physiological concentrations of serum testosterone provided appropriate replacement therapy in wethers. Growth rate, e...

The withdrawal of older workers from the labour force creates a variety of economic challenges, including an increase in unused production capacity. Costs due to early retirement measured in terms of forgone output averaged 6.3 per cent of potential gross domestic product in the OECD in 1998. These costs, which vary greatly from country to country, are highest in Hungary (15.9 per cent of poten...

AbsrmtThis paper describes a method to minimize the total energy to communicate data over a frequency selective fading channel using multicarrier data transmission. The energy is minimized given a desired aversge bit e m r rate at a fixed gross bit rate. For a number of configurations the optimal energy distribution is calculated analytically. For other Eonfigurations we present a generic numer...

Four male lambs (Katahdin; average live weight 25.9±2.9 kg) with "T" type cannulas in the rumen and proximal duodenum were used in a 4×4 Latin square experiment to evaluate the influence of supplemental dry distillers grain with solubles (DDGS) levels (0, 10, 20 and 30%, dry matter basis) in substitution for dry-rolled (DR) corn on characteristics of digestive function and digestible energy (DE...
