In highly water-poor areas, rooftop rainwater harvesting (RRWH) can be used for a self-sustaining and self-reliant domestic water supply. The designing of an optimal RRWH storage tank is key parameter to implement reliable system. this study, the size tanks in different West Bank governorates was estimated based on monthly (all governorates) daily (i.e., Nablus) inflow outflow (domestic demand,...

We calculate the quarkonic O(?s2) massive operator matrix elements ?AQg(N),?AQqPS(N) and ?Aqq,QNS(N) for twist–2 operators associated heavy flavor Wilson coefficients in polarized deeply inelastic scattering region Q2?m2 to O(?) case of inclusive contributions. The evaluation is performed Mellin space, without applying integration-by-parts method. result given terms harmonic sums. This leads a ...

This research proposes Finger Based Technique (FBT) for non-visual touch screen device interaction designed for blind users. Based on the proposed technique, the blind user can access virtual keys based on finger holding positions. Three different models have been proposed. They are Single Digit Finger-Digit Input (FDI), Double Digit FDI for digital text entry, and Finger-Text Input (FTI) for n...

Background Helicobacter pylori (H. pylori) infection has been associated with gastritis, gastric ulcer, mucosa-associated lymphoid tissue lymphoma and gastric cancer. The prevalence of H. pylori virulence genes have been studied in different populations and from different sources of samples but their prevalence has not been studied in dental plaque in Jordanian people; therefore, the aim of thi...

A total of 500 consecutive patients undergoing upper endoscopy were biopsied and tested for H. pylori infection by the Campylobacter-like organism (CLO) test, culture, histology, and PCR. Serum samples were tested by two different serological assays. Patients were considered H. pylori positive if at least two of the four biopsy specimen-based methods yielded positive results. PCR had the highes...

Recent technological advances have made it possible to produce particles with nanometer dimensions that are uniformly and steadily suspended in traditional solar liquids enhanced the impact of thermo-physical parameters. In this research, a three-dimensional flat plate collector was built using thin single working fluid pipe. The physical model solved computationally under conditions conjugated...
