هدف از این مطالعه بررسی اثر آب تهی شده دوتریم (DDW) در غلظت­های مشخص بر روی سلول­های 29HT- و 480SW- بود. رده­های سلولی محیط RPMI حاوی مختلف DDW به مدت 24، 48 72 ساعت کشت داده شدند سپس درصد بقای روش سنجش سمیت مبتنی برMTT تعیین شد. یافته­ها نقش توأم کاهش افزایش زمان تیمار را مهار رشد اثبات رساند. کم­ترین میزان برای طی با غلظت ppm 30 ترتیب 23% 37% دست آمد. جهت اثرات جانبی دوتریم، طبیعی 12C2C نیز ت...

Offset pulse position modulation (OPPM) and Dicode (DiPPM) have been introduced as new attractive techniques, however, they are suffering from erasure, wrong slot, false alarm errors. in this paper, two types of error correction (EC) codes, Low-Density Parity Check (LDPC) code Reed Solomon (RS) code, where paired the OPPM DiPPM systems to reduce bugs, analyze best EC parameters, choose superlat...

A significant cost in PPM data compression (and often the major cost) is the provision and efficient coding of escapes while building contexts. This paper presents some recent work on eliminating escapes in PPM compression, using bit-wise compression with binary contexts. It shows that PPM without escapes can achieve averages of 2.5 bits per character on the Calgary Corpus and 2.2 bpc on the Ca...

An environment is a set of name-value bindings, maintained for a particular user, tha t are provided to a process at runtime. This can provide a great deal of flexibility in tai loring the behavior of programs to a particular user's preferences. It can also serve as a simple me ans of interprocess communication. To be useful, however, the environment must take into ac count the natural structur...
