Abstract: Let be a commutative ring and be a unitary module. We define a semiprime submodule of a module and consider various properties of it. Also we define semi-radical of a submodule of a module and give a number of its properties. We define modules which satisfy the semi-radical formula and present the existence of such a module.
Introduction: cerebral vein thrombosis is a rare complication of nephrotic syndrome (NS).We report a known case of NS with hemorrhagic thrombosis. Case report: A boy with previous history of NS was admitted with headache and decrease of level of consciousness and his brain images were revealed hemorrhagic thrombosis Conclusions: cerebral vein thrombosis must be considered in patients with...
Regarding the therapeutic properties of Nigella sativa (NS), the effects of the plant hydro – alcoholic extract on learning, memory and brain tissues oxidative damage were investigated in penthylenetetrazole (PTZ) - induced repeated seizures.There were 4 experimental groups including: 1- control group; received saline, 2- PTZ group ; received saline and PTZ (50 mg/kg, i.p) , 3-PTZ- NS 200 and 4...

An R-module M is called epi-retractable if every submodule of MR is a homomorphic image of M. It is shown that if R is a right perfect ring, then every projective slightly compressible module MR is epi-retractable. If R is a Noetherian ring, then every epi-retractable right R-module has direct sum of uniform submodules. If endomorphism ring of a module MR is von-Neumann regular, then M is semi-...
The concepts of free modules, projective modules, injective modules and the likeform an important area in module theory. The notion of free fuzzy modules was introducedby Muganda as an extension of free modules in the fuzzy context. Zahedi and Ameriintroduced the concept of projective and injective L-modules. In this paper we give analternate definition for projective L-modules. We prove that e...
one of the main problems following road accidents is brain injury after which death and disability in the most active population occurs. considering the fact that there is no definite clinical treatment for repair of damaged brain tissue, the present study examined the effects of autologous adult neural stem/progenitor cells (ns/pcs) seeded in a nanoscaffold named puramatrix in acute brain inju...
Introduction: Education and learning systems are globally evolving toward self-learning-based educational models. The purpose of this study was to determine the features and principles of developing a self-learning module, compare the self-learning module with other methods of teaching, and explore the effects of self-learning module on learning. Methods: In this review study, data were collect...
