ADiesel cycle enginewith internal and external irreversibilities of finite combustion rate of the fuel, friction and heat leakage is investigated in this paper. The heat transfer between the working fluid and the environment outside the cylinder obeys generalized radiative heat transfer law [q ∝ ∆(T n)]. Under the conditions of the fixed total cycle time and fuel consumed per cycle, the optimal...

for purposes of planning and programming of environmental health activities at the community level, it is important to gather information regarding people's need, demands, and the basic socio demographic data, as well as relevant community resources. it is more likely, that in this way, the people not only will participate and get involved with the programme, but the health activities will be m...

Two high-fat containing side streams from the chocolate industry were evaluated as an alternative renewable substrate for biochemical long-chain dicarboxylic acid (DCA) production by Candida tropicalis. Cleaning water liquid transport and dissolved air flotation (DAF) sludge wastewater treatment plant contained 29 18 m% fat respectively. The addition of up to 100 g.L−1 ‘chocolate water’ 80 % (v...

background: high consumption of nonalcoholic beverages is one of the causes of dental erosion. annual consumption of beverages in iran is 48 lpcy (lit per capita per year) that is equal to 144 bottles per capita in year and is relatively a high rate. taking this into consideration, the present study was planned to determine the ph and fluoride content of beverages consumed in kerman, south east...

The geological disposal of spent nuclear fuel may represent a good solution after a thorough risk assessment. In Finland and Sweden, the host rock for geological disposal is crystalline rock and the repository is based on the Swedish KBS-3 multi-barrier design. When radionuclides from spent nuclear fuel are potentially released into the bedrock, they are then transported by advection along wate...

In this research, the energy flow and production energy indices of canola cultivation in Trakya province of Turkey, Golestan and Mazandaran provinces of Iran were compared. Diesel fuel and chemical fertilizer inputs were the highest consumer of energy in the production of canola in these three regions. The results indicated that despite the higher energy use of machinery in Trakya province of T...
