The critical study of political discourse has up until very recently rested solely within the domain of the social sciences. Working within a linguistics framework, Critical Discourse Analysis (CDA), in particular Fairclough (Fairclough 1989, 1995a, 1995b, 2001; Fairclough and Wodak 1997), has been heavily influenced by Foucault. 2 The linguistic theory that CDA and critical linguistics especia...
Equation (2) has some oscillation behavior [1-3], In 2012, Liu [4] obtained some oscillation criteria of eq. (1). In the last decades, the Emden-Fowler equations have attracted extensive attention for the relevance to nuclear physics and gaseous dynamics in astrophysics, the oscillation behavior of the Emden-Fowler equations are studied by many scholars [5-10]. In this paper, we further study f...

The objective of this paper is applying the well-known exact operational matrices (EOMs) idea for solving the Emden-Fowler equations, illustrating the superiority of EOMs over ordinary operational matrices (OOMs). Up to now, a few studies have been conducted on EOMs ; but the solved differential equations did not have high-degree nonlinearity and the reported results could not strongly show the...
در سال های اخیر مطالعه و تحقیق درباره ی معادلات دیفرانسیل مرتبه دوم غیرخطی منفرد مورد توجه بسیاری از ریاضیدانان و فیزیک دانان قرار گرفته است. دسته ای از این معادلات، معادلات lane-emden می باشند که شکل کلی آن ها به صورت زیر آمده است. که در آن تابعی مجهول، a و b اعداد ثابت، تابعی پیوسته و حقیقی مقدار و تابعی که روی بازه [0,1] مشتق پذیر است. یک روش عددی برای حل معادلات lane-emden منفرد با شر...
The recently developed theory of quasi-Lie schemes is studied and applied to investigate several equations of Emden type and a scheme to deal with them and some of their generalisations is given. As a first result we obtain t-dependent constants of the motion for particular instances of Emden equations by means of some of their particular solutions. Previously known results are recovered from t...
SCC: squamous cell carcinoma INTRODUCTION Chronic arsenic exposure is rare in developed nations. The few cases of arsenical keratosis in the United States have primarily been attributed to occupational and medicinal exposures. Here, we describe a case of an elderly man in whom arsenical keratoses and cutaneous cancers developed decades after being treated with oral Fowler solution, for the trea...
