Some Flat-Based Celts from Kent and Dorset

extraction 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 ...

Brickearth and Clay- With-flints from Kent

ABS~CT Particle-size analyses of brickearth and Clay-with-flints from Kent, England, are presented. A calcareous sample of brickearth is comparable to loess. In th~ clay fraction, there is more illite (or glauconite) than kaolin; and there is some chlorite. The clay fraction of the Clay-withflints consists of smectite, illite and quartz and is probably derived directly from the Chalk. Black san...

report, was the deep divergence of the rosada lineage at the base of the Conolophus clade. “The species alters the current thinking about the timing of diversification of land iguanas, which was previously supposed to have occurred in the Pleistocene era,” the researchers write. “In addition to the taxonomic implications, this form, which we recognise as a good species, is very important becaus...

Cauchy Kernels for some Conformally Flat Manifolds

Here we will consider examples of conformally flat manifolds that are conformally equivalent to open subsets of the sphere S. For such manifolds we shall introduce a Cauchy kernel and Cauchy integral formula for sections taking values in a spinor bundle and annihilated by a Dirac operator, or generalized Cauchy-Riemann operator. Basic properties of this kernel are examined, in particular we exa...
