Although there isn't any quality control criteria and standards for its monitoring. So quality of the examinations may decline, and the main objective of the examinations, maintaining and improving employees' health, m...
In Ref. [1] Robicheaux and Shaw calculate quantum photoabsorption spectra of atoms in electric fields with nonzero magnetic quantum numbers, m 6= 0 and observe recurrence peaks at short actions in the Fourier transform recurrence spectra. For spectra with magnetic quantum number m = 0 these peaks can be directly interpreted as the recurrences of the “uphill” and “downhill” orbit along the elect...

Shi (2000) claims that topics must be related to a syntactic position in the comment, thus denying the existence of dangling topics in Chinese. Under Shi's analysis, the dangling topic sentences in Chinese are not topic-comment but subject-predicate sentences. However, Shi's arguments are not without problems. In this paper we argue that topics in Chinese can be licensed not only by a syntactic...
در این کار پژوهشی اثر کاتالیزوری نانوذره‌های Co3O4 برروی واکنش نورتابی شیمیایی لومینول ـ اکسیژن مولکولی انجام یافته در محیط قلیایی نشان داده شد. نانوذره‌های Co3O4با روش ترسیب تند سنتز شدند و سپس با روش‌های میکروسکوپ الکترونی روبشی (SEM)، پراش پرتو ایکس (XRD)، میکروسکوپ الکترونی عبو...
