Mechanical Heating Ventilation and Air-Conditioning (HVAC) systems account for 60% of the total energy consumption of buildings. As a sector, buildings contributes about 40% of the total global energy demand. By using passive technology coupled with natural ventilation from wind towers, significant amounts of energy can be saved, reducing the emissions of greenhouse gases. In this study, the de...

Since the introduction of closed chest synchronized DC shock treatment for atrial fibrillation by Lown in 1962 (Lown, Amarasingham, and Newman, 1962a; Lown et al., 1962b) many thousands of patients have undergone this treatment. Complications have occurred on occasion. Arrhythmias, some fatal, have been reported by Ross (1964), Morris et al. (1964), Killip (1963), and Turner and Towers (1965). ...

We investigate products of sets reals with combinatorial covering properties. A topological space satisfies S 1 ( ? , ) if for each sequence point-cofinite open covers the space, one can pick element from cover and obtain a space. prove that, there is an unbounded tower, then nontrivial set satisfying in all finite powers. In contrast to earlier results, our proof does not require any additiona...
