Objective It is thought that mothers who conceive via assisted reproductive technology (ART) may be at greater risk of postpartum depression (PPD) because of the problems and psychological stresses associated with ART treatment. The aim of the present study is to determine the occurrence of PPD among mothers conceiving via ART in comparison with mothers naturally conceiving, using Edinburgh Pos...

many academics, worldwide have considered khatami’s dialogue of civilizations as a pow-erful rhetoric and antithesis of the so-called ‘clash of civilization’ theory. this article, how-ever, tries to show the originality and depth of khatami’s vision, framed against the back-ground of ‘the end of history’ and clash of civilization’ theories, political frames used by po-litical actors in the post...

the sacred art of islam has undoubtedly been born with the calligraphy of the holy quran. afterwards, it was completed and evolved with decorating of this magnificent manifest. this process has had great effects on all fields of islamic art. in this research, the writer has discussed about the procedure of scribing the holy quran in the life time of the holy prophet (p.b.u.h) as well as the tim...

residual stress measurement has gained interests among researchers for many years due to its great influence on the structural integrity. slitting method is one of the destructive techniques that relies on the introduction of an increasing cut to a part containing residual stresses. similar to all other mechanical strain relief techniques, slitting also suffers from its shortcomings during the ...

to investigate the effect of dietary supplementation of l-carnitine on resistance to temperature and salinity stresses in sobaity fry, an experiment was carried out with 240 pieces of fish with average initial weight of 3.01±0.03 g for 10 weeks. experimental treatments were consisted of four levels of 0, 500, 1000 and 1800 (respectively control, lc500, lc1000 and lc1800) mg l-carnitine per kg o...

statement of problem: currently there are three recognized theories about the diameter of prepared dowel space in endodontically treated teeth. diameter of the dowel is commonly contributed to the root fracture. purpose: this study used a 3 dimensional (3d) finite element method to predict stress distribution in endodontically treated central maxillary tooth with cast post and core with various...

a plain strain analysis of frictional rolling contact on an elastic graded coating is presented in this paper. finite element method is applied to gain an understanding of the stresses and contact zone properties caused during rolling contact. the effects of friction, material stiffness ratio and coating thickness on stresses in contact zone and coating/substrate interface are studied. shear mo...

after springs production, different residual stresses are created in the inner and outer surfaces of spring wires. some of these stresses for example compressive residual stresses are useful and some are harmful. the effects of vareation of these stresses are caused spring relaxation and decrising in their free length when they are loaded intermittently. for review this phenomena in this resear...

water salinity and drought are the major abiotic stresses limiting turf grass growth. on the other hand, shortage of waterresources and salinity of water and soil in the arid and semi-arid zones such as iran, are the restricting factors in developinglawn turf grasses. an experiment was conducted to evaluate the combined effects of water salinity and deficit irrigation ontall fescue (festuca aru...
