A series of studies were conducted using dual energy X-ray absorptiometry (DXA) to measure energy and protein deposition in pigs. In an initial validation study DXA was compared directly with slaughter analysis as a method for measuring energy deposition in pigs. During growth from 30 to 60 kg the mean value for carcass energy deposition measured by DXA was 251 MJ compared to 249 MJ by chemical...
Due to global climate change, greenhouse gas (GHG) analyzes for agricultural production systems are becoming more common with energy analyzes. In this study, carbon dioxide (CO2) emissions in the Harran Plain due fuel consumption first crop seed corn were evaluated. A total of 100 face-to-face surveys conducted a producers and data collected on processes. The calculations determine CO2 released...
Biomass has become an increasingly important resource for energy generation. The influence of the chemical composition on heating value biomass not been a thoroughly studied subject, as shown by bibliometric analysis. It is well known that lignin significantly higher (23.26–25.58 MJ/kg) than polysaccharides (18.6 MJ/kg), while extractives often have HHVs over 30 MJ/kg, depending their oxidation...
High-fiber diets in pregnant sows: digestive utilization and effects on the behavior of the animals.
Twelve pregnant, multiparous sows were assigned during gestation to three dietary treatments in a 3 x 3 Latin square design to evaluate the effect of increasing levels of crude fiber (CF): a conventional diet low in CF (L, 15.8 MJ DE/kg of DM, 3.3% CF), a diet with a medium level of CF (M, 14.4 MJ DE/kg of DM, 10.6% CF), and a high-fiber diet (H, 12.9 MJ DE/kg of DM, 18.1% CF). The daily feed s...
For the first time, this work investigates achievability of developing a biorefinery concept around almond hulls by hydrothermal treatment (HTT), thoroughly scrutinising influence temperature (200–300 °C), pressure (100–180 bar), time (20–180 min) and solid loading (5–25 wt%). This process allowed conversion into four main products: gas (2–13%), bio-oil (2–12%), aqueous (4–69%) hydro-char (17–8...
The diets of 20 children with cystic fibrosis were analysed for energy and nutrient content with simultaneous measurement of energy losses in stools. Median energy intakes were in excess of the WHO estimated daily requirements (118.2%) when expressed as MJ/kg/24 hours, the excess almost accounted for by energy losses in the stools. When expressed as MJ/24 hours, however, median energy intakes w...
Abstract The present study was carried out to investigate biodiesel production via transesterification of sunflower oil employing heterogeneous catalyst derived from indigenous ginger (Zingiber Officinale) leaves. It also aims compare the techno-economy performance ginger-based catalysts in 3 different forms viz. calcinated (CGL), activated by KOH (KGL) and NaOH (NGL). plant-based were characte...
The structural and mechanical properties of graphene-like honeycomb monolayer structures of MoS2 (g-MoS2) under various large strains are investigated using density functional theory (DFT). g-MoS2 is mechanically stable and can sustain extra large strains: the ultimate strains are 0.24, 0.37, and 0.26 for armchair, zigzag, and biaxial deformation, respectively. The in-plane stiffness is as high...
The utilization of biomass can not only alleviate the energy crisis but also reduce pollution fossil fuels to environment. Biomass gasification is one main methods, which effectively convert into high-value and wide-use gas. However, this process inevitably produces by-product tar, affects yield syngas. In order solve problem, a two-stage combining pyrolysis CO2 catalytic reforming proposed in ...
