In this paper we study the Diophantine equation x4− q4 = py5, with the following conditions: p and q are different prime natural numbers, y is not divisible with p, p ≡ 3 (mod20), q ≡ 4 (mod5), p is a generator of the group (
I summarize three recent calculations of electromagnetic reactions on deuterium in chiral perturbation theory. All of these calculations were carried out to O(Q4), i.e. next-to-next-to-leading order. The reactions discussed here are: elastic electron-deuteron scattering, Compton scattering on deuterium, and the photoproduction of neutral pions from deuterium at threshold.
INTRODUCTION Enhanced external counterpulsation (EECP) is a noninvasive outpatient treatment used for patients with intractable angina refractory to aggressive surgical and medical treatment. Recent results have demonstrated a positive impact of EECP on patients with ischemic heart disease (IHD)-associated erectile dysfunction (ED). AIM To assess the effect of IHD duration and number of EECP ...
The relative age effect (RAE) and its relationships with maturation, anthropometry, and physical performance characteristics were examined across a representative sample of English youth soccer development programmes. Birth dates of 1,212 players, chronologically age-grouped (i.e., U9's-U18's), representing 17 professional clubs (i.e., playing in Leagues 1 & 2) were obtained and categorised int...
Trends in the labor market, as a result of global economic recession, are characterized by reduction of manpower activity, decreased number of employed and increased number of unemployed persons. As the result of economic recession more then million workplaces are expected to be lost in the European Union. The aim of this study was to analyze the influence of economic recession on labor market ...
Molecular dynamics simulations employing reactive potentials were used to determine the activation barriers to the dissolution of the amorphous SiO2 surface in the presence of a 2 nm overlayer of water. The potential of mean force calculations of the reactions of water molecules with 15 different starting Q4 sites (Qi is the Si site with i bridging oxygen neighbors) to eventually form the disso...
OBJECTIVE The objective of this study was to determine the relationship between added sugar and dietary diversity, micronutrient intakes and anthropometric status in a nationally representative study of children, 1-8.9 years of age in South Africa. METHODS Secondary analysis of a national survey of children (weighted n = 2,200; non weighted n = 2818) was undertaken. Validated 24-hour recalls ...
BACKGROUND AND PURPOSE Studies have linked elevated total homocysteine (tHcy) levels to atherosclerotic carotid plaque development, but data are limited to predominantly white populations. We examined the association between tHcy and carotid plaque burden and morphology in a multiethnic cohort. METHODS In the Northern Manhattan Study, we conducted a cross-sectional analysis among 1327 stroke-...
A low urine flow rate is a marker of acute kidney injury. However, it is unclear whether a high urine flow rate is associated with a reduced risk of contrast-induced nephropathy (CIN) in high-risk patients. We conducted this study to evaluate the predictive value of the urine flow rate for the risk of CIN following emergent percutaneous coronary intervention (PCI). We prospectively examined 308...
This paper examines how journal-, article-, and author-related factors influence citation counts in the business field using 236 journal articles collected from an AACSB medium research output school Middle East between 2017 2021. Results association tests demonstrated that rank format, subfield of article, author prestige are significantly related to number citations. CHAID further presence in...
