In this study, experiments were conducted to investigate the production of biogas from vegetable wastes by using anaerobic digestion process. The complete-mix, pilot-scale digester with working volume of 70 l was used. The experimental protocol was defined to examine the effect of the change in the organic loading rate on the efficiency of the production of biogas and to report on its steady-st...

introduction high-producing dairy cows require large amounts of concentrates that are rich in energy and crude protein to meet their nutrient requirements. cereal grains and oil supplements are commonly used for increasing energy density of diets fed to high-producing dairy cows. dietary grain source (barley vs. corn) and oil supplement (soybean- vs. fish oil) resulted in varied dry matter inta...

Anaerobic sludge digestion is the main technology for sludge reduction and stabilization prior to sludge disposal. Nevertheless, methane production from anaerobic digestion of waste activated sludge (WAS) is often restricted by the poor biochemical methane potential and slow hydrolysis rate of WAS. This work systematically investigated the effect of PHA levels of WAS on anaerobic methane produc...

background: knowledge production and evaluation are two important functions of health research system (hrs). in this article, we aimed to reveal the correlation between evaluation of health research organizations and health knowledge production promotion. methods: a comprehensive evaluation system was developed to evaluate the academic performance of national medical science universities on an ...

This study aims at assessing how bilinguals select words in the appropriate language in production and recognition while minimizing interference from the non-appropriate language. Two prominent models are considered which assume that when one language is in use, the other is suppressed. The Inhibitory Control (IC) model suggests that, in both production and recognition, the amount of inhibition...

Heavy quark production has been for years a closely scrutinized process, as it has represented one of the very few instances in which experimental measurements and next-to-leading order (NLO) QCD predictions seemed to be at variance. Such a disagreement appeared surprising, as one expects perturbative QCD to be able to handle heavy quark predictions well, due to the (relatively) large scale set...

The advantage of the adversarial regime of judicial decision-making is the superior information of the parties, while the advantage of an idealized inquisitorial regime is its neutrality. We model the tradeoff by characterizing the properties of costly estimators used by each regime. The adversarial regime uses an ‘extremal’ estimator that is based on the difference between the most favorable p...

French children program the words they write syllable by syllable. We examined whether the syllable the children use to segment words is determined phonologically (i.e., is derived from speech production processes) or orthographically. Third, 4th and 5th graders wrote on a digitiser words that were mono-syllables phonologically (e.g. barque=[baRk]) but bi-syllables orthographically (e.g. barque...

introduction: evaluation of the cerebrospinal fluid (csf) white blood cell (wbc) count and glucose and protein concentrations is used to assess the probability of the presence of central nervous system (cns) infection. although normal values are well established for csf cell counts and protein and glucose contents in children and adults, this is not the case for neonates. the purpose of this st...
