ساختار کلاسهایی از حلقه های z- موضعی و c- موضعی the structure of some classes of z-local and c-local rings

فرض کنیمr یک حلقه تعویض پذیر ویکدار موضعی باشدو(j(r رایکال جیکوبسن r و(z(r مجموعه مقسوم علیه های صفر حلقه r باشد.گوییم r یک حلقه z- موضعی است هرگاه j(r)^2=. .همچنین برای یک حلقه تعویض پذیر r فرض کنیم c یک عنصر ناصفر از (z( r باشد با این خاصیت که cz( r)=0 گوییم حلقه موضعی r یک حلقه c - موضعی است هرگاه و{0 و z(r)^2={cو z(r)^3=0, نیز xz( r)=0 نتیجه دهد که x عضو {c,0 } است. در این پایان نامه ساخ...

the effect of classroom observation on eflteachers skills ans students outcomes

abstract the following study, in the first place, attempted to examine the effect of less experienced teachers participation in experienced teachers classes on their own skills and teaching methodology, in the second place, attempted to find out the role of teachers training in students achievements. for this purpose, 21 efl teachers were selected according to available sampling in kish l...

Matter-wave solitons of collisionally inhomogeneous condensates

Spatially inhomogeneous phase of asymmetric nuclear matter

We study the isospin singlet pairing in asymmetric nuclear matter with nonzero total momentum of the condensate Cooper pairs. The corresponding BCS equations are derived and solved within the finite temperature retarded realtime Green’s functions formalism. The quasiparticle excitation spectrum is four-fold split compared to the usual BCS spectrum of the symmetric, homogeneous matter. A two-fol...

Magneto-optical Effects in Transparent Media under Inhomogeneous Magnetization

The analysis of the Magneto-Optical (M. 0.) effects when the magnetization is inhomogeneous is separated in two cases : first, when no diffraction occurs inside the medium, the geometrical optics approximation is used to derive the phase of the optical fields and the ray paths. Second, with no negligible diffraction inside themedium, extensions of the previous theory are presented and applied t...
