the purpose of this research was to evaluate the recovery potential of solid waste in mashhad. the solid waste generated in the regions 4, 5 and 6 has been quantified and characterized using direct weighing, physical testing and truckload sampling methods. to determine the quantity and quality of waste generated and its seasonal variations, chemical and physical analysis were carried out for on...

Fatty acid methyl ester (FAME) or biodiesel is a biofuel conventionally produced from edible oil and methanol, using an alkaline catalyst, through a transesterification reaction. As FAME is mostly produced from edible vegetable oils, crop soils are used for its production, increasing deforestation and producing a fuel more expensive than diesel. In addition, between 70 and 80% of the total FAME...

Due to human activities huge amount of organic wastes are simply dumped in the environment creating disposal and pollution problems. Suitable and sustainable utilization of these wastes is vermicomposting which converts wastes in to wealth. In the present study, 1:1 proportion (wt./wt.) of vegetable market waste (VMW) and press mud (sugar industry waste) mixture have been used for vermicomposti...

In Brazil, and mainly in the State of Bahia, crude vegetable oils are widely used in the preparation of food. Street stalls, restaurants and canteens make a great use of palm oil and soybean oil. There is also some use of castor oil, which is widely cultivated in the Sertão Region (within the State of Bahia), and widely applied in industry. This massive use in food preparation leads to a huge a...

In recent years, the problem of food waste has attracted considerable interest from food producers, processors, retailers, and consumers alike. Food waste is considered not only a sustainability problem related to food security, but also an economic problem since it directly impacts the profitability of the whole food supply chain. In developed countries, consumers are one of the main contribut...

Biodiesel, as renewable and biological origin alternative diesel fuel, has been receiving a lot of concern throughout the world due to the energy needs and environmental awareness. However, at present, it is not economically feasible to use food-grade vegetable oils to produce biodiesel because of the surge in feedstocks price. Much attention has been devoted to the application of lower-cost fe...

The role of dynamic instabilities in the initiation of reentry in diseased (remodeled) hearts remains poorly explored. Using computer simulations, we studied the effects of altered Na(+) channel and cell coupling properties on the vulnerable window (VW) for reentry in simulated two-dimensional cardiac tissue with and without dynamic instabilities. We related the VW for reentry to effects on con...

Background Von Willebrand ́s disease (VWD) is the most common congenital disorder of hemostasis, characterized by deficient or defective von Willebrand factor. Patients are treated by intravenous replacement of factor VIII/VW (FVIII/ VW) when needed, for prophylaxis before surgical procedures. Anaphylactic reactions to FVIII/VW are rare and desmopressin (DDAVP) can be used as an alternative.
