In the case of oscillatory potentials, new oscillation criteria are established for the forced nonlinear differential equations ` |x′(t)|αsgnx′(t) ́′ + q(t)|x(t)|sgnx(t) = g(t) (β > α > 0). (*) Our results generalize and improve the main result of Nasr [3] for equation (∗) with α = 1, β > 1 and can be applied to extreme cases such as R∞ t0 q(t)dt = −∞ and R∞ t0 g(t)dt = −∞.

In the paper, the existence of positive solutions is studied for the second-order delay differential equation with a damping term ẍ(t)+ a(t)ẋ(t)+ b(t)x(h(t)) = 0 using a comparison with the integro-differential equation ẏ(t)+ ∫ t t0 e ∫ t s a(ξ)dξb(s)y(h(s))ds = 0. Explicit non-oscillation criteria and comparison type results are derived. © 2010 Elsevier Ltd. All rights reserved.

metabolic syndrome is highly prevalent in type 2 diabetics and is a strong risk factor for cardiovascular diseases in such patients. the aim of this study was to determine the prevalence of metabolic syndrome according to the three criteria of atpiii, idf and the new criteria for metabolic syndrome diagnosis in kerman, iran. this cross-sectional study was performed on 950 diabetic type 2 patien...

BACKGROUND Non-specific electrocardiographic ST-T wave changes and voltage criteria for left ventricular hypertrophy (LVH) have been associated with cardiovascular morbidity and mortality. The aim of the cohort study was to evaluate the prognostic value of non-specific ST-T changes and LVH electrocardiographic criteria on cardiovascular events and mortality in hypertensive patients. METHODS A...

By means of Mawhin’s continuation theorem, we study a kind of third-order p-Laplacian functional differential equation with distributed delay in the form: ( φp(x ′(t)) )′′ = g ( t, ∫ 0 −τ x(t+ s) dα(s) ) + e(t), some criteria to guarantee the existence of periodic solutions are obtained. Keywords—p–Laplacian, Distributed delay, Periodic solution, Mawhin’s continuation theorem

INTRODUCTION Septal deviation is the chief cause of chronic nasal obstruction. In order to treat such cases, nasal septoplasty surgery is usually performed based on patient complaints and a surgeon's examination, both of which are subjective. This study aims at using the objective parameters of acoustic rhinometry and rhinomanometry to evaluate the effectiveness of septoplasty surgery. MATERI...

BACKGROUND Investing in financial markets is promoted and protected by the government as an essential economic activity, but can turn into a gambling addiction problem. Until now, few scales have widely been used to identify gambling addicts in financial markets. This study aimed to develop a self-rating scale to distinguish them. In addition, the reliability and validity of the stock addiction...
