 The behavior of ions in a Paul trap has been investigated using numerical solution of the set of Mathieus differential equations. Afterwards, the trajectories of two typical ions such as H+ and 208Pb+ in the trap have been obtained using the fourth-order Runge-Kutta method. For specific dimensions of a Paul trap and a given frequency, the stability regions for separation of H+ and 2H+ ions hav...

in chapter one we will describe definitions and preliminary results to provide the global context of our own results to be presented in detail in the subsequent chapters in chapter two we consider degree-one maps of the circle and we study their rotation set. our main result in this chapter says that if the map is topologically mixing then its rotation interval is nontrivial (that is, not reduc...

در تحقیق حاضر، با استفاده از ترکیب تئوری dsd و روش level set جبهه تراک تعقیب شده است. نخست، با استفاده از یک کد dsd یا از طریق مراجع، روابط d-? و d ?-d-? برای مواد شدیدالانفجار و مخلوط های گازی به دست آورده شده است، سپس با استفاده از روش level set، جبهه تراک در هندسه های مختلف تعقیب شده است. برای مواد شدیدالانفجار که در آن ها انحنا نقش مهمی را در دینامیک جبهه تراک دارد، همخوانی خوبی بین نتایج ت...

‎let $x$ be a real normed  space, then  $c(subseteq x)$  is  functionally  convex  (briefly, $f$-convex), if  $t(c)subseteq bbb r $ is  convex for all bounded linear transformations $tin b(x,r)$; and $k(subseteq x)$  is  functionally   closed (briefly, $f$-closed), if  $t(k)subseteq bbb r $ is  closed  for all bounded linear transformations $tin b(x,r)$. we improve the    krein-milman theorem  ...

in this article, we have shown, for the add-point monad t, thepartial morphism category set*is isomorphic to the kleisli category sett. alsowe have proved that the category, sett, of t-algebras is isomorphic to thecategory set of pointed sets. finally we have established commutative squaresinvolving these categories.

in this study, aerial parts of lippia citriodora kunth were harvested at three phenological stages (i.e. vegetative, full flowering and fruit set). the essential oil isolated by hydro distillation for 3 h using a clevenger-type apparatus and the oil was analyzed by gc and gc-ms. the yields of oils (w/w%) in different stages was in the order of: full flowering (0.9%), vegetative (0.48%) and frui...

background: fungi may play a key part in periradicular diseases. the aim of this study was to evaluate and compare the antifungal properties of two root-end filling materials, proroot mineral trioxide aggregate (mta) and mta-angelus, against candida albicans using tube-dilution test. materials and methods: the antifungal properties of proroot mta and mta-angelus against c. albicans was assessed...
