in this project, 4,4?-methylenebis(3-chloro-2,6-diethyl trimellitimidobenzene) as a diacid, was prepared by the reaction of trimellitic anhydride (tma) with 4,4?-methylenebis(3-chloro-2,6-diethylaniline) (mcdea). the novel poly(amide-imide) (pai) was synthesized from the reaction of 4,4?-methylenebis(3-chloro-2,6-diethyl trimellitimidobenzene) as a diacid with mcdea under green condition using ...
چکیده diphyllidea van beneden in carus, 1863 راسته ای است از رده eucestoda که گونه های آن همگی تنها در دریاها زیست کرده و از گونه های مختلف سفره ماهی و یک خانواده از کوسه ماهیان به عنوان میزبان نهایی استفاده می کنند. در این مطالعه گونه ای جدید از جنس coronocestus caira, marques, jensen, kuchta and ivanov, 2013 متعلق به راسته diphyllidea از یک گونه کوسه ماهی به نام iago omanensis (norman) از د...
abstract although music possesses some kind of power and using it has been welcome by many students in language classrooms, it seems that they take a non-serious image of the lesson while listening to songs and they may think that it is a matter of fun. the main objective of the present study was to investigate whether learning a foreign language through musical texts (songs) can have an impac...

Background: The current study tried to investigate the antioxidant and anti-bacterial effects of green tea and grape seed extract (with a volume of 2%) on durability of Tilapia packed inpolyethylene bags, which were kept in cool temperature of 4 ± 1 °C. Methods: Prepared fish were divided into 3 batches: 2 batches were treated by dipping for 30 min in ethanolic of green tea extract (...
an isolated fusarium anthophilum (a. braun) wollenweber (isolate 16c) has been considered as a candidate for microbial control of barnyard grass [echinochloa crus-galli (l.) p. beauv]. the effects of nutrition on conidiation, germination rate and germ-tube elongation of conidia of the fungus were evaluated. conidia yield, conidial germination and conidial germ-tube elongation of the fungus grow...
this work is presented in five parts. in the first part preparation of the starting complex [pt(c^n)cl(dmso)], 1, in which c^n = n(1),c(2?)-chelated, deprotonated 2-phenylpyridine, and dmso = dimethylsulfoxide, and its reaction with 1 equiv of the biphosphine ligands bis(diphenylphosphino)amine, dppa, or bis(diphenylphosphino)methane, dppm, to give the complex [pt(c^n)cl(dppa)], 2, or [pt(c^n)c...
decentralized control strategies are popular candidates in microgrids control because of their reliability and performance. conventionally, droop control (as a main decentralized strategy) is been utilized in order to prevent permanent droop of voltage and frequency after change in loads and also to share generated power between distributed generation units. in this paper, a new droop control s...
این پایان نامه به تشریح و تبیین نتایج مقاله ی زیر می پردازد: g. zeng, henselian valuations and orderings of a commutative ring, proc. amer. math. soc. 135(2007), 929- 938. هدف اصلی در مقاله فوق بررسی ارتباط بین ارزیاب های هنسلی و ترتیب ها(یا نیم ترتیب ها) روی یک حلقه می باشد. نتیجه اصلی این است که برای ارزیاب هنسلی v روی حلقه r شرایط زیر معادلند: ارزیاب v با هر نیم ترتیب روی r سازگار است؛...
The present study was undertaken to investigate the role of banana extract (BE) on synchronous plantlet formation from seeds of Dendrobium lituiflorum Lindl. The seedlings formed on modified Knudson C (KC) medium supplemented with 20% (v/v) BE had significantly high fresh and dry weights. Morphologically uniform plantlets with elongated leaves and well developed roots were formed on KC medium w...
