Organochlorinated pesticides, PCBs, dioxins, and PBDEs in grey mullets (Liza ramada) and allis shads (Alosa alosa) from the Vilaine estuary (France).
This study aimed to compare the contamination levels of various organohalogenated compounds in two migratory fish species in the Vilaine River in western France. Organochlorinated pesticides, polychlorinated biphenyls (PCBs), dioxins (polychlorinated dibenzo-p-dioxins/dibenzofurans (PCDDs/Fs)), and polybrominated diphenyl ethers (PBDEs) were analyzed in two diadromous species from the Vilaine e...
متن کاملthe role of russia in transmission of energy from central asia and caucuses to european union
پس ازفروپاشی شوروی،رشد منابع نفت و گاز، آسیای میانه و قفقاز را در یک بازی ژئوپلتیکی انرژی قرار داده است. با در نظر گرفتن این منابع هیدروکربنی، این منطقه به یک میدانجنگ و رقابت تجاری برای بازی های ژئوپلتیکی قدرت های بزرگ جهانی تبدیل شده است. روسیه منطقه را به عنوان حیات خلوت خود تلقی نموده و علاقمند به حفظ حضورش می باشد تا همانند گذشته گاز طبیعی را به وسیله خط لوله مرکزی دریافت و به عنوان یک واس...
15 صفحه اولAllis shad (Alosa alosa) exhibit an intensity-graded behavioral response when exposed to ultrasound.
Most fish cannot hear frequencies above 3 kHz, but a few species belonging to the subfamily Alosinae (family Clupeidae) can detect intense ultrasound. The response of adult specimens of the European allis shad (Alosa alosa) to sinusoidal ultrasonic pulses at 70 and 120 kHz is tested. The fish showed an intensity-graded response to the ultrasonic pulses with a response threshold between 161 and ...
متن کاملMitochondrial DNA variation, genetic structure and demographic history of Iranian populations
In order to survey the evolutionary history and impact of historical events on the genetic structure of Iranian people, the HV2 region of 141 mtDNA sequences related to six Iranian populations were analyzed. Slight and non-significant FST distances among the Central-western Persian speaking populations of Iran testify to the common origin of these populations from one proto-population. Mismatch...
متن کاملA Study on the Properties of Alosa (Alosa caspia) By-Products Protein Hydrolysates Using Commercial Enzymes
In current study, protein hydrolysates were produced using microbial proteases of Alcalase, Protamex and Flavourzyme from by-products (head, skin and viscera) of Alosa (Alosa caspia), a major Clupeonella species in the Caspian Sea. The results indicated that the protein hydrolysate from Alcalase, had the highest protein content (78.91%), protein recovery (80.42%) and degree of hydrolysis (21.06...
