Canadian researchers are now trying to exploit much more energy from solar sources, hydropower, wind, and biomass. Given the fact that reducing the carbon pollutant level is a political priority in Canada, this paper studies the feasibility of providing sanitary hot water and space heating demands of a four-member family in 10 provinces in this country. The feasibility analysis was performed by...

Present study reports analgesic activity of petroleum ether, chloroform, ethyl acetate and methanolic extracts of leaves and seeds of Trigonella foenum-graecum Linn. (Fabaceae) using hot plate method for evaluation of central analgesic activity and acetic acid induced writhing test for evaluation of peripheral analgesic activity in mice.   All the extracts of Trigonella foenum-graecum ...

A search for a two-body transition Υ (3S) → γA0, where A0 is a light scalar particle, followed by its decay into 2 muons has been performed using a data sample of (121 ± 1.2) × 106 Υ (3S) decays. As ΓΥ (4S)/ΓΥ (3S) ≈ 10 3, one has greater sensitivity to rare decays using Υ (3S) decays than Υ (4S) samples. The Standard Model (SM) predicts the existence of the Higgs boson to account for the diffe...

Massive stars are the cosmic engines that shape and drive our Universe. Many issues such as their formation, their stability and the mass loss effects, are far from being completely understood. Recent ground-based and space observations have shown pulsations in massive MS and post-MS stars, such as acoustic and gravity modes excited by the κ-mechanism and even solar-like oscillations. Theoretic...

Menopause is coincident with ovarian failure in women, resulting in a relatively rapid fall in levels of estrogens. Although there is no comparable hormonal event in men, some do have hot flashes. In Sweden, it was found that 33.1% of noncastrated men reported hot flashes [1]. The underlying mechanisms for this are not known. In women, hot flashes are the most common symptom of menopause and ar...

It is a pleasure to edit this issue of The Reasoner and I am grateful to Michael Friedman for agreeing to be interviewed for the purpose. Michael is Frederick P. Rehmus Family Professor of Humanities as well as the executive director of the Center for History and Philosophy of Science (CHPS) at Stanford University. He is primarily known for his contributions in at least two areas: the philosoph...

Western society is at the brink of an atrial fibrillation (AF) explosion. Already AF is the most common sustained arrhythmia worldwide; in the US alone the estimated prevalence in 2010 was between 2.7 to 6.1 million, and this is expected to rise to between 5.6 and 12 million by 2050 [1]. The source of this increase is multifactorial and our current ability to manage the condition is often subop...
