Background: Region 5 of Tehran is a very large and important zone due to population, size, geographical position and number of areas. This region is appropriate for performing separation of solid wastes plan. This study investigated economical and environmental potential of municipal solid wastes in region 5 of Tehran. Methods: This descriptive cross-sectional study was performed in 2011. D...
A parafoil controlled by parafoil brake de ection offers a lightweight and space-ef cient control mechanism for autonomous placement of air-dropped payloads to speci ed ground coordinates. The work reported here investigates control issues for a parafoil and payload system with left and right parafoil brakes used as the control mechanism.It is shown thatparafoilandpayloadsystems can exhibit ...
abstract in aggregate, active forms of reactive silica with mineral names are sometimes associated with sand and gravel in concrete mixture. alkali hydroxides originated from alkalis in the cement or other resources form an alkaline silica gel with this reactive silica which becomes swallowed and expanded during time causing damage to concrete. there have been growing researches on alkaline r...
Background and Aim: One of the common problems of children all over the world is short stature. Due to the high costs of treatment, the present research studied the cost-effectiveness of growth hormone (Somatropin) for the treatment of children with short stature in Kerman Province. Materials and Methods: This research is an economic evaluation. The population of the study consisted of all per...
In decentralized construction projects, costs are mostly related to investment, material, holding, logistics, and other minor costs for implementation. For this reason, simultaneous planning of these items and appropriate scheduling of activities can significantly reduce the total costs of the project undertaken. This paper investigates the decentralized multiple construction projects schedulin...
Because pigs frequently lose their footing and slip, it is important to understand slipping and its relation to different floor surfaces. An experiment was conducted to evaluate the gait and footing of young pigs walking on concrete floor surfaces having known friction characteristics and to determine critical skid resistance values in terms of the fitness of a concrete surface for flooring in ...
introduction: hospitals as important sector of health care system has special location in health economic science. increasing of the operational costs in hospital and limitation in financing cause that hospital as an economic firm use cost analysis and prepare effective using of resource and boost productivity. therefore this study was conducted to calculate daily- patient hotel cost in hospita...
Title of Thesis: Control of Construction Costs During Construction David H. Foo, Master of Science in Management Engineering, 1981 Thesis directed by: Dr. John M. Ciborski, Special Lecturer The construction of a major project requires a vast amount of time, money, material and human resources. Proper coordination of these elements into an array of activities is crutial to the success of the pro...
proposing a robust designed facility location is one of the most effective ways to hedge against unexpected disruptions and failures in a transportation network system. this paper considers the combined facility location/network design problem with regard to transportation link disruptions and develops a mixed integer linear programming formulation to model it. with respect to the probability o...
