A combined pyrolysis and gasification process for sewage sludge was studied in this paper for the purpose of its safe disposal with energy self-balance. Three sewage sludge samples with different dry basis lower heat values (LHV(db)) were used to evaluate the constraints on this combined process. Those samples were pre-dried and then pyrolysed within the temperature range of 400-550 degrees C. ...

Does dietary composition in itself have any importance for weight gain and obesity? Meta-analyses of dietary intervention trials comparing ad libitum normal-fat diets with low-fat diets clearly demonstrate that a reduction in the dietary fat content decreases body fat stores (Bray & Popkin, 1998; Yu-Poth et al. 1999; Astrup et al. 2000). Energy from fat has a weaker satiating power than energy ...

the objectives of this study were to determine the energy use efficiency and economical potential of sugar beet production in miandoab city, west azerbaijan province in 2011-12. fields were classified into three groups as group i (less than 1 ha), group ii (1-2 ha), and group iii (more than 2 ha). inputs and outputs data were collected from growers using questionnaire and interview methods. res...

Recent advances in the design of molecular photoswitches have opened up opportunities for storing solar energy strained isomeric structures and releasing heat on demand, culminating thermal (MOST) storage densities over 0.3 MJ kg−1 validating potential achieving battery applications.

The Vendée Globe is a solo round-the-world sailing race without stopovers or assistance, a physically demanding challenge for which appropriate nutrition should maintain energy balance and ensure optimum performance. This is an account of prerace nutritional preparation with a professional and experienced female racer and assessment of daily nutritional intake (NI) during the race using a multi...

Solid waste management is challenging in Phnom Penh city, Capital of Cambodia. The only one formal treatment taken is the final disposal of mixed waste into an open dumpsite. The current study analyses the physical and chemical characteristics of municipal solid waste disposed of in the dumpsite to assess their suitable handling methods. The current study found that the major compositions of wa...

The aim of this study was to assess the effects of 2 weeks of supplementation with (-)-hydroxycitrate (HCA) and HCA combined with medium-chain triglycerides (MCT) on satiety and energy intake. The experimental design consisted of three intervention periods of 2 weeks separated by washout periods of 2 or 6 weeks in a double-blind, placebo-controlled, randomized, and crossover design. Seven male ...

Recent results suggest that wild Northern herbivores reduce their metabolism during times of low ambient temperature and food shortage in order to reduce their energetic needs. It is, however, not known whether domesticated animals are also able to reduce their energy expenditure. We exposed 10 Shetland pony mares to different environmental conditions (summer and winter) and to two food quantit...

The study investigated the effects of re-alimenting dietary protein or energy on growth, carcass characteristics and meat eating quality parameters of sheep. Twenty-seven intact rams (~9 months; 11.3 ± 0.5 kg) were randomly divided into three groups. Each group was fed a maintenance diet (MT) containing, on dry matter (DM) basis, 105 g/kg crude protein (CP) and 8.4 MJ/kg DM metabolizable energy...

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...
