The present study was conducted on efficiency of utilization of dietary energy for milk production in lactating crossbred cattle. 18 lactating crossbred cattle of early to mid-lactation, approximate body weight (375.39±23.43 kg), milk yield, parity and stage of lactation were divided into three groups of six animals each and were fed 0, 50 and 100% diammonium phosphate (DAP) in the mineral mixt...
The spectroscopy and photodissociation dynamics of the vinoxy ~CH2CHO! radical B̃( A9) ←X̃(A9) transition have been investigated by fast beam photofragment translational spectroscopy. We show conclusively that excitation to the B̃ state is followed by predissociation, even for the origin transition. Two photodissociation channels are observed: ~1! CH31CO, and ~2! H1CH2CO, with a branching ratio of...
In present PET/CT scanners, PET attenuation correction is performed by relying on the information given by CT scan. In the CT-based attenuation correction methods, dual-energy technique (DECT) is the most accurate approach, which has been limited due to the increasing patient dose. In this feasibility study, we have introduced a new method that can implement dual-en...
A 2×2×2 factorial arrangement with control group was conducted to study the effect of different levels of microbial phytase, metabolizable energy and available phosphorus on performance, carcass characteristics and phosphorus and calcium content of tibia in broiler chicks. In this experiment, 1260 Ross 308 male broiler chicks allocated to 9 treatments in a factorial arrangement, with 2 levels o...
Boars (entire male pigs) consume less feed than barrows (castrated male pigs) under practical ad libitum feeding conditions, but the knowledge about possible reasons is only limited. Since the lysine and energy contents of the diet are known to be important determinants of voluntary feed intake, it was of interest if sex specific responses to selected dietary lysine-toenergy ratios could explai...
In the present study, investigated an energy production system using three types of renewable energy: solar, wind and ocean thermal energy with climatic conditions and close to areas with high potential for the OTEC system, Has a good position in terms of wind speed and solar radiation, used them as energy sources. The proposed system is designed and evaluated based on the total daily electrici...
The contribution from the divergent part of the horizontal wind to the energy conversion between the vertical shear flow and the vertical mean flow has been computed using atmospheric data from the isobaric surfaces: 850, 700, 500, 300, and 200 mb. The new calculations supplement earlier computations giving the energy conversion based on an assumption that the horizontal winds are non-divergent...
The paper presents an investigation of fix-referenced and self-referenced wave energy converters and a comparison of their corresponding wave energy conversion capacities from real seas. For conducting the comparisons, two popular wave energy converters, point absorber and oscillating water column, and their power conversion capacities in the fixed-referenced and self-referenced forms have been...
