A gas permeation model (Coupling Model) has been developed which has the flexibility to be used for different membrane module configurations. The aim of this work is to predict the performance of a single stage gas separation process using membranes and provide a comprehensive description of process parameters like flow rates, composition, stage cut and stream pressure. The significant feature ...
Nowadays, numerous processes of any supply chain are done by suppliers and consequently they cause a massive amount of pollution released to the nature. Hence, greening the suppliers has become a necessity. Although most of green supplier development programs need high investment, formal optimization models that address this issue are very rare. This paper mainly aims to address this prob...
abstract in first part of this project, the use of a new and biguanid-like catalyst supported on silica as a recyclable catalyst provides a new route for the synthesis of a variety of arylalkylidene rhodanine derivatives through knoevenagle reaction in at present of solvent at room temperature. rhodanine derivatives and especially arylalkylidene rhodanines have proven to be attractive compound...
this article aimed to study the development of memory in transition from preoperational to the operational stage in 120 children in the age range of 4 to 8. in order to test the cognitive level (intelligence), the conservation test of seriation was applied. children were asked to draw from memory what they had done during seriation test. the test was administred at different intervals: one hour...
هدف: کشت سلول های اسپرماتوگونی و تولید سلول های پر توان embryonic stem cells (es like cells) که دارای قابلیت بازسازی و تولید هرسه نوع لایه زایای جنینی می باشند، این سلول ها را به عنوان منبع کافی و جدیدی برای سلول درمانی و ترمیم در بیماریها از جمله بیماریهای نورودژنراتیو پیشنهاد می دهد. در تحقیق حاضر تمایز سلول های اسپرماتوگونی موش به سلول های شبه الیگودندروسیت و نقش آنها درمیلین سازی پس از پیون...
Parathyroid hormone-like hormone (PTHLH) was first identified as a parathyroid hormone (PTH)-like factor responsible for humoral hypercalcemia in malignancies in the 1980s. Previous studies demonstrated that PTHLH is expressed in multiple tissues and is an important regulator of cellular and organ growth, development, migration, differentiation, and survival. However, there is a lack of data on...
At the present time, terminology resources for various domains and languages are being actively developed. For low-resource languages like Tatar, terminology compilation may be a challenge in many respects: because of the insufficient degree of terminology development that leads to absent relevant designations for special concepts in a language; because of lacking special sources for assembling...

Pomegranate has two types of flowers on the same plant: functional male flowers (FMF) and bisexual flowers (BF). BF are female-fertile flowers that can set fruits. FMF are female-sterile flowers that fail to set fruit and that eventually drop. The putative cause of pomegranate FMF female sterility is abnormal ovule development. However, the key stage at which the FMF pomegranate ovules become a...
