فرض کنید $ r $ و $ s $ دو حلقه و $ {}_sc_r $ یک دو مدول شبه دوگان باشد. در این پایان نامه ما رابطه ی بین $ g_{c} $-مرابطه با $ c $-مرابطه و هم چنین رابطه ی بین تحلیل $ g_{c} $-تصویری و تحلیل تصویری از یک مدول را بررسی می کنیم. به علاوه نشان می دهیم که اگر egin{center} $ mathbf{g}^{ullet} : cdots ightarrow g_{1} ightarrow g_{0} ightarrow g^{0} ightarrow g^{1} ightarrow cdots$ end{center}...
Introduction: Patients with high or low body mass index may be more at risk of death and complications after surgery, especially in patients who have coronary artery bypass grafting may be the outcome could be more specific, so we decided to evaluate effect BMI and its correlation with survival and outcome in cardiac surgery. Methods: A Cross sectional study of 345 patients who underwent sur...
In this paper, we extend the Unruh-DeWitt (UDW) model to include a relativistic quantized center of mass (c.m.) for detector, which traditionally has classical c.m. and follows trajectory. We develop an inertial detector following two different approaches, starting from either first- or second-quantized treatment, enables us compare fundamental differences between schemes. particular, find that...
quinazolinones are interesting materials because of their valuable biological effects. in this study some new 2,3-disubstituted-4(3h)quinqzolinone derivatives were synthesized from anthranilic acid in six steps by introducing a new chiral center to the aliphatic side chain of the quinazolinone. in the last step, a single acylation on the hydrazine moiety afforded final compounds. the structures...
In this paper, the invariant mass spectra of Λ (1405)→(Σπ)0 in high energy proton-proton collisions in center of mass frame have been theoretically investigated. In pp collision the Λ (1405) formation possibility has been taken into account and its decay rate to (Σπ)0 channel, has been calculated with T-matrix elements and Green’s function method. Finally, the results have been compared with ...
