زمینه و هدف: حفظ انحنای کانال ضمن آماده نمودن آن از اهمیت ویژه ای برخوردار است. در درمانهای اندودنتیک همیشه تلاش می شود که شکل نهایی کانال تغییر نکند و کاملاً دربرگیرنده شکل اولیه آن باشد. مطالعه حاضر با هدف تعیین میزان حفظ انحنای کانال در ریشه های داندنهای مولراول بالا و پایین، در موارد درمان ریشه شده و ارزیابی روش step- back به عنوان روش کلاسیک در آماده سازی این دندانها انجام شد.روش بررسی: طی ...
the main purpose of this research paper is to compare qiujiahe formation (є1q) and longmaxi formation (s1ln) in north sichuan basin where shale gas exploration has not been fully researched, and hence represents the possibility of shale gas concentration under the complex geological conditions. based on valid laboratorial analysis, there are optimistic prospects for є1q and s1ln of research are...
during natural gas processing, water in natural gas may cause to hydrates formation in pipelines which may lead to serious damages to process equipments. given the problems raised by present of water in natural gas, glycol solvent uses to remove water.in contact of glycol with gas always an amount of btex and voc absorb along with water, which on glycol recovery process, these substances separa...
The in vitro biosynthesis of taxiphyllin and the channeling of intermediates in Triglochin maritima.
The in vitro biosynthesis of the cyanogenic glucoside taxiphyllin has recently been demonstrated in Triglochin maritima (Hösel, W., and Nahrstedt, A. (1980) Arch. Biochem. Biophys. 203, 753-757). We have now studied in more detail the multistep conversion of tyrosine into p-hydroxymandelonitrile, the immediate precursor of taxiphyllin, catalyzed by microsomes isolated from dark-grown seedlings....
Cassava (Manihot esculenta Crantz), although native to Brazil, is still underutilized, especially when it comes to using its aerial part. In order to study the potential of the cassava plant for use as animal feed, the present work evaluated the characteristics of the aerial part of cassava when submitted to the processes of ensiling and haymaking. Treatments consisted of: aerial part of the pl...
