physical design of the emergency department (ed) has an important effect on its role and function. to date, no guidelines have been introduced to set the standards for the construction of eds in iran. in this study we aim to devise an easy-to-use tool based on the available literature and expert opinion for the quick and effective assessment of eds in regards to their physical design. for this ...
gol-e-gohar iron ore mine of sirjan in southern part of iran is a large open pit that operates below the groundwater table and during mining operation, dewatering is required to prevent operation processes from flooding. current operation is going on by digging wells in or out of the pit and pumping to prevent flooding. as a result of the former dewatering operation a vast deep cone of depressi...
We investigated the effect of viewing conditions on human visual perception of colorfulness and constructed a mathematical model for colorfulness by fitting regression curves to LUTCHI color appearance data. This model enables the simple and effective prediction of the relative appearance attribute of colorfulness as a function of brightness and saturation, taking into account a range of viewin...
In order to recognize objects on the basis of the way in which they reflect different wavelengths of light, the visual system must deal with the different illuminant and background conditions under which the objects are seen. To test this ability under natural conditions, subjects were asked to name 6 uniformly colored papers. The experiment started by showing subjects six papers simultaneously...
Producing food colors from natural sources, such as tomatoes, which could be used instead of synthetic colors, is important in relation to health and safety aspects of the consumers. In this research, solvent extracting was carried out by using three non-polar solvents, including petrolium ether (bp=55°C), n-hexane (bp=60°C) and a mixture of n-hexane: ethanol: aceton (1:1:2, bp=50°C). Also, two...
Lipases catalyze hydrolysis and synthesis of triacylglycerols. These enzymes,especially the microbial ones, have wide commercial and industrial usage. Bacillus subtilis <span style="color: ...
Energy delivery at well construction in regions with hard climate is distinguished by variable demand in electric and heat power. Energy consumption of drilling equipment, production and living facilities varies greatly during the year, depending on power load charts and climate conditions. Power supply of remote well construction sites is mostly accomplished by operating autonomous power sourc...
objective: selection of an appropriate shade of composite is critical in achieving an esthetic restoration. different systems are used to assess and describe color parameters. this study aimed to assess the effect of color and thickness of filtek supreme (fs) and premise (p) composite resins on correction of tooth discoloration. methods: in this in vitro experimental study, 10 anterior teeth ...
Background and Objective: Approximately, half of the occupational accidents are associated with the construction industry in Iran. Therefore, the factor analysis of risk variables affecting occupational injuries in the construction industry can lead to understanding and reducing the rate of injuries in these projects. The purpose of this study was to identify the risk factors affecting the type...
labyrinth spillway is an appropriate option to pass pmf discharge. the most advantages of this type of spillway are higher discharge capacity, easy aeration as well as low fluctuations of flow surface. it is essential to find the optimum geometry considering the maximum passing discharge under specific hydraulic conditions with minimum construction cost. in this study, fuzzy inference system (f...
