از فرآیند گرمای القائی در تکنولوژی و صنعت در موارد زیادی مانند جوش فلزات، بازپخت، متالورژی ]1[ رشد بلور ]4-2[، و ... استفاده می شود. در این روش ماده فلزی مورد نظر (قطعه کار مانند بوته)، داخل یک پیچه ی القائی قرار می گیرد. سپس با ایجاد یک جریان الکتریکی متناوب فرکانس بالا درپیچه (جریان رانشی)، میدان های الکتریکی و مغناطیسی متناوبی در اطراف پیچه ایجاد می شوند. با نفوذ این میدان ها در ماده فلزی مو...

Anxiety and depression are among the mental disorders that are highly prevalent in advanced and developing societies. Statistics show that one in five people, especially women, suffer from these disorders at some point in their lives. In Iran, the prevalence of anxiety is 15.6% and depression is 12.7% (Khademian et al., 2021, Mohammadi et al., 2019)

We present a full quantal study on the dissociation of weakly bound molecular ion in presence an external time-dependent electric field. focus dynamics Paul trap relevant for atom-ion hybrid traps. Our results show that survives giving theoretical ground to previous experimental findings [A. Kr\"ukow et al. Phys. Rev. Lett. 116, 193201 (2016) and A. Mohammadi Research 3, 013196 (2021)]. In part...

In recent years, the production of nutritious snacks has received much attention. Food industry by-products represent an abundant source of nutrients and are often used as an animal feed. Sunflower seed meal is high in protein and essential amino acids, minerals and vitamins and mohammadi rose (R. Damascena) waste, contains high amounts of phenolic compounds. In the present study, sunflower see...

In geometric, algebraic, and topological combinatorics, the unimodality of combinatorial generating polynomials is frequently studied. Unimodality follows when polynomial (real) stable, a property often deduced via theory interlacing polynomials. Many open questions on stability pertain to enumeration faces cell complexes. this paper, we relate shellability We first derive sufficient condition ...

Let $G$ be a real Lie group, $\Lambda<G$ lattice and $H<G$ connected semisimple subgroup without compact factors with finite center. We define the notion of $H$-expanding measures $\mu$ on $H$ and, applying recent work Eskin-Lindenstrauss, prove that $\mu$-stationary probability $G/\Lambda$ are homogeneous. Transferring construction by Benoist-Quint drawing ideas Eskin-Mirzakhani-Mohammadi, we ...
