the present study conducted to investigate the effect of energy sources and levels on performance and breast meat amino acids profile in cobb 500 broiler chicks. a total of 600 1-day-old cobb 500 broiler chicks with an average weight of 39 ± 0.50 g were randomly divided into five treatments. each treatment was further divided into four replicates. chicks were fed a basal diet based on corn and ...

The precise data for the total cross section σ(ee → hadrons) from the charm threshold region, when combined with the evaluation of moments with three loop accuracy, lead to a direct determination of the short distance MS charm quark mass mc(mc) = 1.304(27). Applying the same approach to the bottom quark we obtain mb(mb) = 4.191(51) GeV. A complementary method for the determination of mb is base...

Equation of motion of Sommerfeld sphere in the one-dimensional potential hole, produced by two equal charges fixed at some distance from each other, is numerically investigated. Unusual result is found: due to the fact that sphere gains much more velocity then it should be according to relativistic equation of motion of point charge without radiation force, the sphere on its motion from one wal...

We report on an experiment with polarized atoms passing a standing light wave, where the atom’s position is encoded (entangled) with the excitation amplitude of two long lived electronic states. Position information can be obtained a posteriori by measuring the electronic state. If this measurement is performed, the atom is localized in an array of virtual slits. This gives rise to diffraction ...

In this work, we derive a result of exact controllability for a structural acoustic partial differential equation (PDE) model, comprised of a three-dimensional interior acoustic wave equation coupled to a two-dimensional Kirchoff plate equation, with the coupling being accomplished across a boundary interface. For this PDE system, we show that by means of boundary controls, the interior wave an...

Background & Aim: Energy is one of important debates in agriculture ecology and for this reason; the ratio of output and input energy in different agriculture ecosystems has been calculated. If one can reduce, input energy level into farms through the indices like poisons, fertilization, tractor energy and lab our force. In addition to the net income of the farmers, this issue would play a sign...

A theoretical approach to calculating the dipole moment function of a diatomic molecule at very small internuclear separations has been suggested. The approach is based on the united-atom model and the LS-coupling approximation. Regularities in the behavior of the dipole moments as functions of the internuclear separation, electronic state, and nuclear charge of the molecule have been found. Wi...

The smart grid revolution is creating a paradigm shift in distribution networks that is marked by new, significant intermittencies and uncertainties in power supply and demand. These developments include the dramatic increase in the adoption of distributed energy resources (DER), electric vehicles, energy storage, and controllable loads. This transformation imposes new challenges on existing di...
