Membrane electrogenesis and sodium transport in filamentous nitrogen-fixing cyanobacteria.
Transport of Na+ and its relationship with membrane potential (delta psi m) was examined in Anabaena L-31 (a fresh water cyanobacterium) and Anabaena torulosa (a brackish water cyanobacterium) which require Na+ for diazotrophic growth. The data on the effect of N,N'-dicyclohexylcarbodiimide indicated that delta psi m was generated by electrogenic proton extrusion predominantly mediated by ATPas...

15 صفحه اولNew Records of Nostocalean Cyanobacteria from Rice Fields in the Golestan Province in North-East of Iran
The algal flora of five stations from paddy-fields of Golestan Province was investigated between October 2006 and September 2007. Eight filamentous heterocystous Nostocacean are recorded here for the first time from paddy fields of iran: Cylindrospermum licheniforme, Cylindrospermum stangnale, Cylindrospermopsis raciborskii, Calothrix ghosei, Gloeotrichia longiarticulata, Aulosira implexa var. ...

در این رساله با معرفی سقف های psscb متشکل از ترکیب ورق های فولادی ذوزنقه ای و تخته های سیمانی الیافی به عنوان سقف های پیش ساخته (سازگار با سیستم سازه ای قاب های فولادی سبک) به بررسی پارامترهای موثر بر صلبیت سقف، پرداخته می شود. در تحقیق حاضر ابتدا به مدل سازی دو نمونه سقف آزمایش شده، به روش اجزاء محدود با استفاده از نرم افزار تحلیلی abaqus ver 6.10 پرداخته شده است. نمونه های ساخته شده تحت اعما...
the effect of taftan pozzolan on the compressive strength of concrete in the environmental conditions of oman sea (chabahar port)
cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...
