Shirbot (Barbus grypus) as a species with high potential for aquaculture development recently propagated artificially in South Iran Aquaculture Research Center to extend the species diversity in polyculture system. To provide an effective economic diet for this species 9 experimental diets containing three crude protein levels (250, 300, and 350 g kg -1 ) and three metabolizable energy levels (...

Background and Purpose: Most projections of the global energy use predict that biomass will be an important component of primary energy sources in the coming decades. Short rotation plantations have the potential to become an important source of renewable energy in Europe because of the high biomass yields, a good combustion quality as solid fuel, ecological advantages and comparatively low bio...

INTRODUCTION A six-year research program, “Premium Grains for Livestock”, funded by the Grains R&D Corporation, several animal R&D Corporations and Ridley Agriproducts is focussed on improving the quality of cereal grains for livestock. Cereal grains provide the major source of energy for animals raised in intensive production systems. However, the energy available from cereal grains can vary w...

Harmful algal blooms (HABs) are becoming more invasive and ever prevalent due to rises in nitrogen phosphorus pollution watersheds. Herein, we introduce a novel biorefinery that taps into the vast sources of Contaminated water is diverted flow over attached algae systems, feeding native, periphytic cultures scrubbing excessive nutrients from with produced biomass converted fuels through hydroth...

Detailed measurements of aerodynamic heating rates in the wake of a Mars-Pathfinder configuration model have been made. Heating data were obtained in a conventional wind tunnel, the NASA LaRC 31" Mach 10 Air Tunnel, and in a high-enthalpy impulse facility, the NASA HYPULSE expansion tube, in which air and CO2 were employed as test gases. The enthalpy levels were 0.7 MJ/kg in the Mach 10 Tunnel,...

Material flows and their contributions to fuel properties are balanced for the mechanical section of a mechanical-biological treatment (MBT) plant producing solid recovered fuel (SRF) for the UK market. Insights for this and similar plants were secured through a program of sampling, manual sorting, statistics, analytical property determination, and material flow analysis (MFA) with error propag...

A pyrolysis of compost for the production of syngas with an explicit H2/CO = 2 or H2/CO = 3 was investigated in this study. The composts were obtained from nonhybrid (perennial) grasses (NHG) and hybrid (perennial) grasses (HG). Discrepancies in H2 evolution profiles were found between NHG and HG composts. In addition, positive correlations for NHG composts were obtained between (i) H2 yield an...

BACKGROUND AND AIMS Intestinal failure defined by the minimal energy and wet weight absorption required to avoid home parenteral nutrition (HPN) is not well described. Thus the aim of this study was to identify the minimal level of gut function necessary to avoid parenteral support using objective measurements of intestinal function. METHODS Energy (bomb calorimetry) and wet weight absorption...
