متن کاملextraction and acetylation of purified trypsin from bovin pancreas and study of some its physico-chemical properties
آنزیم تریپسین در شرایط قلیایی ناپایدار می باشد .و فعالیت پروتئولیتیکی تریپسین منجربه خود هضمی آن در جایگاههای خاصی می گردد. بنابر این آنزیمی با ناپایداری بالا محسوب میگردد. در سالهای اخیر موفق شدند که با ایجاد تغیرات شیمیایی با اضافه کردن فلزات خاص ، کلسیم و یا عمل استیلاسیون منجر به افزایش پایداری آنزیم تریپسین گردند. مطالعات در حال حاضر نشان می دهد که تریپسین استیله شده فعالیت آنزیمی خود را ...
15 صفحه اولAnalytical Modeling and Simulation of SAW Filter Using Concave
A Simple novel tool has been developed to model and simulate SAW filter devices. GNU Concave; Freeware tool with open source coding has been used to specify a basic model for SAW delay lines and filters. This paper presents a way for obtaining the essential parameters of design and development of SAW devices as insertion loss. Other parameters were also predicted by within the reseach work like...

متن کاملThe microstructural properties of sputtered zinc oxide SAW transducers
2014 The microstructural properties of sputtered zinc oxide, ZnO, were investigated and related to their effective surface acoustic wave, SAW, transducer capabilities. SAW transducer films were fabricated on glass using different deposition parameters to produce different levels of transducer efficiency. The ZnO film microstructure was analysed using X-ray diffraction, surface profilometer and ...
