The presence of wall strengtheners in double-stage electrostatic precipitators affects gas velocity, electrical field and particle movement over the ESP. In this work we have used our previous mathematical model for double-stage ESP {Talaie et. al (2001) [10]] to study the effect of wall strengtheners on the performance of double-stage ESP. One of the important findings was that, due to the fac...
Purpose.Increasing the load-bearing capacity of metal arch supports used to maintain mine workings due strengthening in places with highest bending moment. Methods. The stress-strain state rock mass and support is analyzed using ANSYS software package. problem studied three variants: a without strengtheners, one strengthener area maximum moment, strengtheners areas moments. To determine moments...
Although definitions of proprioception sense of joint position may vary, its importance in preventing and rehabilitating athletic injury remains constant: Restoring it after injury allows the body to maintain stability and orientation during static and dynamic activities. Any type of joint injury can interrupt position sense. Proprioceptive programs need to be tailored to the individual patient...
CMC research presents emoticons as visual representations of writers’ emotions. We argue that the emoticons in authentic workplace e-mails do not primarily indicate writers’ emotions. Rather, they provide information about how an utterance is supposed to be interpreted. We show that emoticons function as contextualization cues, which serve to organize interpersonal relations in written interact...
در این پایان نامه خواص و جنبه های مختلف کربن معرفی و مروری کلی بر روشهای ساخت ، ساختار و خواص انواع مختلف کربن از کربنهای bulk(شامل گرافیت ، گرافیت turbostratic، الیاف کربن، دوده هاو ... ) تا کربنهای نانومقیاس (شامل fullerenes ، کپسولهای نانومقیاس ، کربنهای nanotube و ... ) ارائه می شود. عمده کار متوجه کربنهای nanotube(اعم از multi-wall و single-wall ) است و ساختار ، عیوب شبکه ای و روشهای ساخت ...
Aluminum alloys containing Sc are promising materials for high-temperature structural applications due to the high strengthening effect of the Al3Sc (L12 structure) precipitates [1]. Further improvements in strength and nanostructural stability of Al-Sc based alloys are achieved by adding alloying elements, such as Mg, as solid-solution strengtheners. It is important to understand the effects o...
