BACKGROUND A recent cross-national study demonstrated a curvilinear (inverted U-shaped curve) between elderly male suicide rates and the Human Development Index (HDI) fitting the quadratic equation y = a + bx - cx2 where y is the elderly male suicide rate, x is the HDI and a, b and c are constants). This study used only one-year cross-sectional data on suicide rates, and suicide rates can rando...

Two established surgical techniques, Y-U antral advancement flap pyloroplasty and inverted pylorus duodenal plasty are used to treat the pyloric stenosis in dogs. The study was conducted on twelve healthy dogs of same age and body weight. The dogs were divided into three groups i.e. Group A, B and C comprising four animals each. The dogs in group A and B were subjected to Y-U antral advancement...

About a half a century has passed since dopamine was identified as a neurotransmitter, and it has been several decades since it was established that people with Parkinson's disease receive motor symptom relief from oral levodopa. Despite the evidence that levodopa can reduce motor symptoms, there has been a developing body of literature that dopaminergic therapy can improve cognitive functions ...

In this paper, a numerical scheme has been developed for primary and secondary fluids adopting Euler–Cauchy method to find the temperature distribution of the primary fluid relative to the secondary fluid and vice–versa and to obtain an optimum boiling length of the tube in the vertical inverted U–tube steam generator (UTSG).

Sequential 12 lead electrocardiograms were recorded during angina pectoris induced by ergonovine maleate in 38 patients with variant angina. Transient U wave inversion was observed in 17 patients with ST segment elevation in anterior chest leads, but in only three of 21 patients with ST segment elevation in the inferior leads associated with right coronary artery spasm. In the 17, all of whom h...

this study attempts to investigate the relationship between pollution and economic growth for two groups of countries according to environmental kuznets curve hypothesis for a sample of 24 developing countries and 26 oecd countries over the period 1980 - 2005. then, we examine this hypothesis using modern econometrics techniques including panel co-integration and panel unit-root. the panel data...
