BACKGROUND
Negative postoperative behavioural changes (NPOBCs) are very frequent in children after surgery and general anaesthesia. If they persist, emotional and cognitive development may beâ€¦ (More)

We improve several results recently established by Dragomir et al. in (2000) for the Gamma and Beta functions. All we need is some clever applications of classical inequalities.

We give an overview of the use of asymptotic expansions of gamma and related functions â€” ratio of gamma functions, powers, digamma and polygamma functions. The aim is to introduce a general theoryâ€¦ (More)

Let s,t be two given real numbers, s = t and m âˆˆ N . We determine the coefficients aj(s,t) in the asymptotic expansion of integral (or differential) mean of polygamma functions Ïˆ (m)(x) : 1 tâˆ’ s âˆ« tâ€¦ (More)

The hydrogen oxidation reaction (HOR) was studied at the home made TiO(x)-Pt/C nanocatalysts in 0.5 mol dm(-3) HClO(4) at 25 degrees C. Pt/C catalyst was first synthesized by modified ethylene glycolâ€¦ (More)

Asymptotic expansion of the arithmetic-geometric mean is obtained and it is used to analyze inequalities and relations between arithmetic-geometric mean and other classical means. Mathematics subjectâ€¦ (More)

In this paper various approximations for the Eulerâ€“Mascheroni constant and harmonic numbers are studied and improved and general asymptotic expansions related to this approximations are obtained.â€¦ (More)
