BACKGROUND In Iran, re-refinery industry has been developed many years ago based on the acid-clay treatment. Acidic sludge with high concentration of total petroleum hydrocarbon (TPH) is the final products of some facilities. In this study removal of TPH by aerated in-vessel composting was investigated. METHODS In order to microorganisms seeding and nutrient providing, urban immature compost ...

Rather than landfilling, composting the organic fraction of municipal solid wastes recycles the waste as a safe and nutrient enriched soil amendment, reduces emissions of greenhouse gases and generates less leachate. The objective of this project was to investigate the composting effectiveness of three bulking agents, namely chopped wheat (Triticum) straw, chopped mature hay consisting of 80% t...

a case of the budd chiary syndrome (bcs) in a 43-yr-old man with hydatid cyst (hc) in the liver is reported from imam ali hospital, kermanshah, western iran in 2016. this case was complicated by inferior vena cava (ivc) thrombosis, right atrial clot and pulmonary emboli. compression of ivc was the likely mechanism. abdominal ultrasonography revealed a huge hc located in segments near ivc and ca...

1. A SUMMARY OF THE GHG IMPLICATIONS OF COMPOSTING During composting, microbial decomposition aerobically transforms organic substrates into a stable, humus-like material (Brown and Subler, 2007). Although small-scale composting, such as backyard composting, occurs across the United States, WARM models composting only in central composting facilities with windrow piles because data for small-sc...

background: the presence of rennin-angiotensin components in mammalian ovaries and their involvement in ovarian physiology have been established. in the present study, effects of angiotensin ii (ang ii) on sodium-potassium adenosine triphosphatase (na+/k+/atpase) expression and development of sheep embryos was evaluated. methods: the abattoir-derived cumulus oocyte complexes (coc) were randomly...

To investigate the regional variability in arterial and venous endothelial prostacyclin (PGI2) biosynthesis, we obtained 1-cm segments of carotid arteries, external jugular veins, femoral arteries and veins, iliac arteries and veins, inferior venae cavae (IVC), and aortas from 17 dogs. Vessel luminal PGI2 production was measured in the basal state by radioimmunoassay of 6-keto-prostaglandin F1 ...

the aim of this study was to determine the optimum mixture ratios for composting separated cattle manure and pepper plant residues. five 127 liter laboratory-scale bioreactor were used to investigate of separated dairy manure addition on the composting process of greenhouse pepper plant residues. cattle manure is considerably rich in nitrogen. however, composting with cattle manure alone is not...

The management of household biowaste in the UK has undergone significant changes during the last decade. Legislation and policy have promoted the rapid development of a diverse composting sector. The sector can be divided into three categories: home composting; community composting; and commercial composting. This paper explores the growth in, and nature of, the commercial and community compost...
