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 اولSpectroscopic LSJ notation for atomic levels obtained from relativistic calculations
Today, relativistic calculations are known to provide a very successful means in the study of open–shell atoms and ions. But although accurate atomic data are obtained from these computations, they are traditionally carried out in jj−coupling and, hence, do often not allow for a simple LSJ classification of the atomic levels as needed by experiment. In fact, this lack of providing a proper spec...

متن کاملConvergence improvement for coupled cluster calculations
Convergence problems in coupled-cluster iterations are discussed, and a new iteration scheme is proposed. Whereas the Jacobi method inverts only the diagonal part of the large matrix of equation coefficients, we invert a matrix which also includes a relatively small number of off-diagonal coefficients, selected according to the excitation amplitudes undergoing the largest change in the coupled ...
متن کاملFully Relativistic ab initio Dirac-Coulomb Calculations of Atomic Properties of Rn and Element 118
Experiments on the production of elements 112-116 in Dubna, Russia, have proven the existence of the enhanced stability of their neutron-rich isotopes. Furthermore, the existence of element 118 has been demonstrated using the Ca beam and the Cf target [1]. The produced 118 isotope has half-life Tα=0.89 +1.07 -0.31 ms in agreement with the theoretical predictions and decays into 114 or 112, whic...
