اسانس های گیاهی با اثرات شناخته شده ای که روی آفات گذاشته اند، می توانند جایگزین مناسبی برای آفت کش های شیمیایی رایج باشند. در این تحقیق، اثرات سمیت تدخینی، تماسی و دورکنندگی اسانس صمغ، میوه و برگ بنهpistacia atlantica desf. subsp. kurdica (zohary) rech. f. روی حشرات کامل سوسک چهارنقطه ای حبوبات callosobruchus maculatus (fabricius, 1775) و شناسایی ترکیبات، اثرات سمیت تدخینی، تماسی و دورکنندگی ا...
Although the thermal mass of floors in buildings has been demonstrated to help shift cooling load, there is still a lack information about how floor covering can influence floor’s load shifting capability and buildings’ demand flexibility. To fill this gap, we estimated flexibility based on daily peak reduction for different configurations regions, using EnergyPlus simulations. As response stra...
The use of air conditioning technology is accompanied by an increase in electricity consumption, which linked to intensification fossil fuel extraction. This turn calls for developing cooling solutions higher energy efficiency. aim this study examine consumption reduction direct evaporative generating cool hot-dry climate regions. At the initial stage, already-installed equipment with a system ...
This paper describes development of an inverse building model and its application in studying the performance of a demand-limiting (DL) control strategy. The demand-limiting strategy involves precooling (PC) a building during unoccupied times, maintaining the zone temperature setpoints at the lower limit of comfort during off-peak, occupied periods, and then limiting the peak cooling rate to a ...
The dual mixed refrigerant (DMR) cycle, which pre-cools natural gas with the mixed refrigerants and then liquefies the natural gas with another set of mixed refrigerants, is well known for having the highest efficiency among the liquefaction cycles. Its possible application to LNG FPSO is also extensively investigated. In this study, the optimal operating conditions, such as the equipment’s flo...
In humans, the relative importance of oxidative fuels for sustaining shivering during passive hypothermic recovery or rewarming is still unclear. The main goals of this study were 1) to quantify the respective contributions of lipids and carbohydrates (CHO) during passive rewarming and 2) to determine the effects of precooling exercise on the pattern of fuel utilization. With indirect calorimet...
Space cooling of buildings shows an increasing trend in energy use worldwide. The exploitation the flexibility reserve obtainable from cooling-loads management can have important role to improve security and reliability electricity power grid. Many studies literature assess potential air conditioning systems; however, specific technology is always scarcely explored. objective this work provide ...
