This paper presents an experimental and numerical study to evaluate the thermal-hydraulic performance of light commercial capacity evaporators operating under frosting conditions. A tube-fin heat exchanger was tested on a closed-loop wind-tunnel considering the fan performance. A visual analysis of the frost formation processes was carried out to compare the frost layer morphology in different ...

Full blown uremic syndrome of chronic kidney disease (CKD) is seldom seen these days due to early initiation of renal replacement therapies (RRT) [1, 2]. Uremic frost is a manifestation of advanced CKD but rarely seen due to effective RRT. We came across a 21-year-old male patient, brought to us with complaints of nausea, anorexia, oliguria and recent onset alteration in sensorium. On physical ...

The effects of topography, soil moisture, wind and grazing on the emergence and survival of seedlings of Festuca spp. were examined in the steppe zone of Patagonia, Argentina. Ungrazed and grazed field treatment plots were established on a plain and a north-facing slope at the Media Luna Ranch (43" 36' S, 71" 25' W). On the leeward and windward sides of each of 15 Festuca plants, 0.1 m x 0.4 m ...

Decenylsuccinic acid induces resistance to desiccation, cold, and frost in young bean plants. When decenylsuccinic acid is sprayed on flowering peach, apple, and pear trees, most of the flowers are resistant to a frost of -6 degrees C.

• Temperature sums required for bud burst can be used to predict risk of spring frost. Provenances with earlier timing display a higher frost damage. Increased events after is projected in warmer climate. A link between growth rhythm provenances and seed orchards needed. The annual cycle boreal trees synchronized seasonal changes photoperiod temperature. climate lead an increased damage caused ...

یکی از مسائلی که در سیستم sar مطرح می شود مسأله نویز speckle می باشد. منبع تولید نویز speckle فاز نسبی پراکنده گرهای مختلف در یک سلول رادار می باشد که نوسانات شدیدی در سیگنال دریافتی به وجود آورده و تصویر حاصل را دانه دانه می نماید. این نویز تفسیر تصاویر را مشکل و اطلاعات زیادی را مخفی می کند و لذا کاهش آن یکی از ملزومات در پردازش سیگنال sar است. الگوریتمهای متعددی جهت کاهش نویز speckle در نوا...
