Switchgrass (Panicum virgatum L.), a US Department of Energy model species, is widely considered for US biomass energy production. While previous studies have demonstrated the effect of climate and management factors on biomass yield and chemical characteristics of switchgrass monocultures, information is lacking on the yield of switchgrass grown in combination with other species for biomass en...

The present study was carried out to evaluate the effect of Mr. Trivedi’s biofield energy treatment on mustard (Brassica juncea) and chick pea (Cicer arietinum) for their growth, yield, and yield attributes. Both the samples were divided into two groups. One group was remained as untreated and coded as control, while the other group (both seed and plot) was subjected to Mr. Trivedi’s biofield e...

We study the plastic yielding of disordered media using the perfectly plastic random fuse model. The yield surfaces are shown to be different from those obtained minimizing the sum of the local yield thresholds, i.e., the so-called minimum "energy" surfaces. As a result, the global yield stress is lower than expected from naive optimization and the difference persists as the sample size increas...

with the increasing world population and limitations on arable land, increasing the yield per unit is one of alternatives human food supply. greenhouse cultivation as one ways of increase the performance can arrive this purpose. but the energy restriction of another human challenges, so that increase the performance without considering energy consumption almost appears to be meaningless. due to...

Size reduction is the first step for manufacturing biofuels from woody biomass. It is usually performed using milling machines and the particle size is controlled by the size of the sieve installed on a milling machine. There are reported studies about the effects of sieve size on energy consumption in milling of woody biomass. These studies show that energy consumption increased dramatically a...

Low voltage operation can markedly reduce the energy requirements of digital circuits; however, in the face of variability it also greatly reduces the reliability and yield. In order to mitigate this effect, device dimensions can be increased and adaptive body biasing can be employed, but at the cost of potentially increasing energy per operation. This paper presents a new framework for determi...

on this project we try to calculated power of hydrogen on dycarbonil compound in different ways ; the first way is shoster way , for sain power of hydrogen notice the different power between central conforms on it and main conform that’s didn’t have hydrogen joint . or in other way different of energy between open and close form. second way, is average way? this is for way that studied conf...

For the calorimetric determination of the primary energy of extensive air showers, measured by fluorescence telescopes, a precise knowledge of the conversion factor (fluorescence yield) between the deposited energy in the atmosphere and the number of emitted fluorescence photons is essential. The fluorescence yield depends on the pressure and the temperature of the air as well as on the water v...

Achieving high dry matter intake (DMI) during early lactation is a major determinant of transition cow management success, as energy balance is tightly linked with reproductive performance (Butler and Smith, 1989) and aspects of health and immunity (LeBlanc, 2010). Although a common notion is that milk yield is the major driver of negative energy balance, several data summaries (reviewed by Gru...
