The identification of odor-active sulfur and nitrogen compounds formed during the processing of dry fermented sausages was the objective of this study. In order to elucidate their possible origin, free amino acids (FAAs) were also determined. The volatile compounds present in the dry sausages were extracted using solvent assisted flavor evaporation (SAFE) and monitored by one and two-dimensiona...

A bench-scale study on swine manure stabilization for odour control was conducted using batch aeration reactors. In trial 1, two aeration lengths, i.e., 0.5 and 4.0 day, were used under uncontrolled ambient temperature that increased gradually over the experimental period. While in trial 2, a 16.0-day aeration scheme was employed under constant 17 degrees C. An airflow rate of 1.2L/s/m(3) was u...

In this study, the performance of two aerobic sequencing batch reactors (SBR) in removing carbon and nutrient (N & P) from Faraman’s industrial estate wastewater (FIW) with flocculated and granulated sludge were compared. The comparison study was performed by varying two significant independent variables (aeration time and mixed liquor volatile suspended solids (MLVSS)). The experiments were co...

 Cypermethrin is a potential toxic pollutant that directly threatens the aquatic ecosystems and environment. Propolis, a natural product collected from plants by honey bees has many functions, such as antimicrobial, antioxidant, and anti-inflammatory. This study attempted to detrmine some biochemical and microbiological parameters of rainbow trout fillets after exposure to propolis an...

An experiment was conducted to develop a plant extracts based quality indicator for monitoring aerobically packed chicken meat quality during storage at room temperature (25±1oC) until spoiled. Ripen black mulberry (Morus nigra) fruit extracts containing anthocyanins was used for developing quality indicator. Filter paper based indicator was exposed to the closed fresh meat environment. Changes...

the main cause for concern about global warming and climate change. Primary air pollutants include carbon monoxide (CO), carbon dioxide, water vapour and un-burnt fuel, hydrocarbons, including volatile and non-volatile organic compounds, oxides of nitrogen, sulphur dioxide (traces), and particulate matter. Pollutants, such as small particles arise not only from the exhaust but also from the roa...

In this research, an experimental study to evaluate nutrient removal from synthetic wastewater by a lab-scale moving bed biofilm process was investigated. Also, kinetic analysis of the process with regard to phosphorus and nitrogen removal was studied with different mathematical models. For nutrient removal, the moving bed biofilm process was applied in series with anaerobic, anoxic and aerobic...

the total nitrogen content of three barley cultivars: cehada capa (resistant at 25ac), cl 1243 (resistant at 5°c) and rika 1 (susceptible at all temperatures) to puccinia hordei was determined and compared in healthy and infected plants at 5° and 26°c. the results indicate that the total nitrogen content of cv. cehada capa leaves was greater than that of cl 1243 and rika 1 and that of cl 12...
