ویژگی های منحصر به فرد تقطیر واکنشی (rd) در ترکیب واکنش و جداسازی، کاهش هزینه ثابت و عملیاتی از جنبه های مورد توجه در چند دهه اخیر است. با این حال، تقطیر واکنشی دارای محدودیت هایی درانطباق واکنش و تعادل فازی است که می تواند مساله چالشی ایجاد کند. فرآیند فیشر-تروپش شامل تبدیل گاز سنتز به هیدروکربن های پارافینی و اولفینی سبک و سنگین می باشد. اختلاف فراریت های نسبی و نقاط جوش متفاوت پارافین ها و ا...
Multi resolution, high temporal fire monitoring and intensity mapping using Himawari-8 Advanced Himawari Imager data [3] This study is focused on utilising the multi-resolution and high frequency data from Advanced Himawari Imager to develop new algorithms for fire line mapping and fire intensity calculation. Two algorithms are proposed for fire line mapping and fire radiant energy: calculation...
this study investigates the effects of melatonin on the sperm quality and testis weight after the combination of swimming exercise and nandrolone decanoate (deca). two groups of male wistar rats were treated for eight weeks as follows; group a consist of co (control), sham, n (deca), s (swimming) and ns (deca plus swimming); and group b: sham m (sham melatonin), m (melatonin), mn (melatonin plu...

In residential heat pump systems, the motivation for secondary loop systems is to allow for the use of flammable or toxic refrigerants with lower global warming potentials than the currently employed HFC refrigerants. The addition of radiant panels as integral building components (embedded in concrete at construction or attached to the underside of wood flooring) is becoming more common. Combin...
The problem of reconstructing the coherent-mode structure of an optical field with unknown crossspectral density function is solved by means of optimal approximating the measured radiant intensity. An alternative field is defined with the coherent-mode structure calculated for the chosen orthonormal basis. An effciency of the proposed technique is illustrated with the results of a numerical sim...
The paper presents a simplified mathematical model to describe the transient heat transfer of a radiant floor heating system. A purpose-built test room has been realized to investigate the actual thermal response of a concrete radiant floor in unsteady-state conditions. Beyond the temperature sensors needed for the standard thermal analysis of the heat transfer inside the chamber, the floor tem...
Patient warming significantly decreases the risk of surgical site infection. Recently there have been concerns that forced air warming may interfere with unidirectional airflow, potentially posing an increased risk of infection. Our null hypothesis was that forced air and radiant warming devices do not increase the temperature and the number of particles over the surgical site when compared wit...
The efficacy of a Gamgee-lined hat in reducing the rate of fall in rectal temperature of infants during the first 30 minutes of life was studied. The trial, which included 211 infants, was randomised, prospective, and controlled. One hundred and seven infants were exposed to overhead radiantheaters. Of these, only 30 had normal deliveries, so the analysis was confined to the infants who were no...
