Municipal solid waste was collected from Varanasi’s municipal solid waste dumpsite and sorted for organic fraction present in it. Current work showed the consequences of calcium hydroxide or lime digestion on organic fraction of municipal solid waste of Varanasi, India. The organic fraction of municipal solid waste sample was digested with desired amount of calcium hydroxide. The different conc...

Abstract Due to the complexity of deterioration process seafood products, relying on one indicator is not adequate determine quality such products. Usually, shelf-life was estimated based various indicators complicating decision-making process. Decision Support Systems are considered as a good solution. The current study aims establish simple and novel fuzzy model combination knowledge- data-dr...

AIM The present study was conducted to examine the rumen modulatory effect of thyme, clove and peppermint oils on rumen fermentation pattern in vitro using roughage based diet. MATERIALS AND METHODS Thyme, clove and peppermint oils were tested at concentration of 0, 30, 300 and 600 mg/l (ppm) of total culture fluid using in vitro gas production technique in wheat straw based diet (concentrate...

The effect of antibiotics of the psychrophilic anaerobic digestion (PAD) of swine manure slurry in sequencing batch reactors (SBRs) was investigated. Six antibiotics, tylosin, lyncomycin, tetracycline, sulphamethazine, penicillin and carbadox, were individually added to the pig diet at their maximum prescribed level. Manure slurries collected from pigs receiving control and medicated diets were...

Polyhydroxyalkanoates are known to be temporarily stored by microorganisms in activated sludge, especially in anaerobic-aerobic processes. Due to the problems resulted from the disposals of plastic wastes and excess sludge of wastewater treatment plants, the production of polyhydroxyalkanoates by treating activated sludge and determining the effect of process variables were the main issues of t...

In this study, hot smoking process was applied to thornback ray (Raja clavata), which is a non-target catch, and the product obtained vacuum packaged then stored at refrigerated conditions (4±1 °C) for 120 days. The nutritional, chemical, microbiological, sensory changes in products were examined every 15 After rays, significant observed nutritional composition of (P<0.05). Total volatil...

The South Pars zone in Iran encompasses the largest gas refineries and petrochemical complexes in the world. In the South Pars zone, elevated concentrations of reactive hydrocarbons co-emitted with nitrogen oxides from industrial facilities lead to substantial ozone production downwind. To understand the role of these emissions on the ozone formation and, to formulate appropriate control st...

VOCs comprise both methane (CH 4) and non-methane volatile organic compounds (NMVOCs). NMVOCs are defined as " all those artificial organic compounds different from methane which can produce photochemical oxidants by reaction with nitrogen oxides in the presence of sunlight " .
