Can we model speech recognition in noise by exploring higher order statistics of the combined signal? How will changes in these statistics affect speech perception in noise? This study addresses these questions in two experiments. One investigated the relationship between an established ”glimpsing” model and the fourth order statistic, kurtosis. The glimpsing model [1] proposes that listeners c...
Polyethylene (PE) nanocomposites containing Cellulose Nano Crystal (CNC) were prepared via melt blending in a twin screw extruder. The evaluation of PE/CNC nanocomposites was studied for food packaging applications. The nanocomposites were investigated by thermal, mechanical analyses. Addition of CNC particle while having no effect on melting and crystallization temperature had intensive effect...
The nutritive value of pistachio epicarp (PE) was evaluated by in situ and in vitro techniques. Chemical analysis indicated that PE was high in crude protein (11.30%) and low in neutral detergent fiber (26.20%). Total phenols, total tannins, condensed tannins and hydrolysable tannins contents in PE were 8.29%, 4.48%, 0.49% and 3.79%, respectively. Ruminal dry matter and crude ...
در این پژوهش نانوکامپوزیت هایی برپایه دو نوع پلی اتیلن سنگین تهیه شده و مورد ارزیابی رئولوژیکی قرار گرفتند. دو پلی اتیلن انتخاب شده دارای اختلاف فاحش در شاخص جریان مذاب بودند. pe-0035 و pe-6070 که به ترتیب دارای شاخص جریان های مذاب 35/0 و gr/mole 8 بودند. ابتدا اثر سازگارکننده های کوچک مولکول نظیر پارافین مالئیکه سنتز شده و برش نفتی h.v.s و پلی اتیلن مالئیکه بررسی شد. سازگارکننده های کوچک مولکو...
r-phycoerythrin (r-pe), a fluorescent protein from phycobiliprotein family, is isolated from red algae. conjugation of antibodies to r-pe facilitates multiple fluorescent staining methods. in the present study polyclonal antibodies and polyclonal f(ab')2 fragment antibodies were conjugated to r-pe by two different methods. the efficiency of the methods was evaluated using immunocytochemistry (i...
فردی که قصد سرمایه گذاری در سهام عادی را دارد، ابتدا لازم است ارزش ذاتی آن سهم را تعیین کرده، سپس با قیمت بازار مقایسه کند. روش برآوردی ارزشیابی قیمت به درآمد، قیمت سهام یک شرکت را به صورت محصولی از سود آن شرکت برآورد می کند. در سال های اخیر، معیار دیگری به نام نسبت peg، به عنوان ابزار شناسایی سهام های مطلوب پدیدار شده است. نسبت peg به صورت ضریب قیمت به سود سهم تقسیم بر نرخ رشد مورد انتظار آن ...

Pleural effusion (PE) is common among ICU and acutely ill patients. Traditionally plain chest radiography (CXR) has been done for pleural effusion evaluation in ICU. However, better results have been reported by ultrasound for the diagnosis of this condition in ICU. In this study, we compared two methods of ultrasound and CXR in PE detection in ICU patients. Also we studied the percentage of t...
