Zarqa, Jordan

The Hashemite University , often abbreviated HU, is a state-supported university located in Zarqa, Jordan.The Hashemite University has a comprehensive campus with a total built-up area of 300,000 square metres , designed in four phases. The fourth design phase was completed in 2005, exceeding 50,000 sqm.The university includes Faculties of Arts, Science, Educational Science, Supporting Medical science Nursing College, Engineering, Literature and many other buildings and related services. It is located on the outskirts of Zarqa on two main highways with a site area of about 1,100,000 square metres , rendering it as one of the largest universities in Jordan.It is uniquely designed with a composition of the various campus buildings dispersed in the landscape while incorporating the latest technological and educational trends. The urban planning considered the environmental, transportation and socio-economic services in addition to the humanitarian aspects and interactions in order to create a homogeneous urban textile. Shaded walkways, pergolas and wind barriers were also designed for protection from high temperature, wind, sun and pollution. It is named after the Jordanian royal family—the Hashemites—and was established in the outskirts of Zarqa by a royal decree in 1995. It started out with four different colleges and expanded to fourteen through the years. Its vision is to achieve an academic pioneering position and excellence in university teaching, scientific research, at both the national and regional levels, to serve society through its educational functions, and to participate in the advancement of knowledge.

In this paper, the energy and exergy utilizations in Jordan are analyzed by considering the energy and exergy flows for the year 2010 in the transportation, residential, and industrial sectors which represent more than 82% of total energy demand in Jordan. Detailed end-use models for the different sectors are established. For the transportation sector, the end-use model is constructed using scattered data from different governmental agencies. Due to lack of information for residential and industrial sectors, surveys covering 200 households and 180 industrial facilities were conducted and energy consumption data was gathered to establish detailed end-use models for the Jordanian residential and industrial sectors. Exergy analysis of Jordan indicates a less efficient picture than that obtained by the energy analysis. Energy and exergy efficiencies of Jordan were found to be equal to 48.2 and 23.2% respectively. It was found that the industrial sector is the most efficient energy and exergy sector. The study emphasizes the usefulness of the current methodology for analyzing sectoral energy and exergy utilization. This study will also provide an insight to energy analysts and policy makers in Jordan when considering the process of implementing energy policy measures such as energy efficiency standards in Jordan. © 2013 Elsevier B.V.

Experimental investigation of overall performance, efficiency and reliability of five types of solar collectors is carried out. The systems involved in this study are blue and black coating-selective copper, copper, and aluminum collectors in addition to evacuated tubes collectors. The experiments were carried out during April under same conditions for all collectors. The sky was almost clear with an ambient temperature in the range 18-26 °C. Readings are collected daily from 8:00 am to 4:00 pm. The solar radiation intensity ranged from 154.0 to 1004.33 W/m2. Considering size of application, cost of appliance, quality and maintenance follow-up, results show that evacuated tube, blue and black coating-selective copper collectors are recommended for medium and large scale applications due to their long life, high efficiency ease of maintenance. Aluminum collectors are recommended for small applications like houses. © 2012 Elsevier Ltd. All rights reserved. Source

This paper presents the effect of the automatic voltage regulator (AVR) gain on the bifurcations of subsynchronous resonance (SSR) in power systems. The first system of the IEEE second benchmark model of SSR is chosen for numerical investigations. The dynamics of both axes damper windings of the generator and that of the power system stabilizer (PSS) are included. The bifurcation parameter is the compensation factor. Hopf bifurcation, where a pair of complex conjugate eigenvalues of the linearized model around the operating point transversally crosses from left- to right-half of the complex plane, is detected in all AVR gains. It is shown that the Hopf bifurcation is of subcritical type. The results also show that the location of the Hopf bifurcation point i.e. the stable operating point regions are affected by the value of the AVR gain. The variation of the location of the Hopf bifurcation point as function of the AVR gain for two operating conditions is obtained. Time domain simulation results based on the nonlinear dynamical mathematical model carried out at different compensation factors and AVR gains agree with that of the bifurcation analysis. © 2009 Elsevier Ltd.

Cryptosporidium is an enteric parasite that is considered the second greatest cause of diarrhoea and death in children after rotavirus. Currently, 27 species are recognised as valid and of these, Cryptosporidium hominis and Cryptosporidium parvum are responsible for the majority of infections in humans. Molecular and biological studies indicate that Cryptosporidium is more closely related to gregarine parasites rather than to coccidians. The identification of gregarine-like gamont stages and the ability of Cryptosporidium to complete its life cycle in the absence of host cells further confirm its relationship with gregarines. This opens new avenues into the investigation of pathogenesis, epidemiology, treatment and control of Cryptosporidium. Effective drug treatments and vaccines are not yet available due, in part, to the technical challenges of working on Cryptosporidium in the laboratory. Whole genome sequencing and metabolomics have expanded our understanding of the biochemical requirements of this organism and have identified new drug targets. To effectively combat this important pathogen, increased funding is essential. © 2015 Australian Society for Parasitology Inc. Source

The purpose of this paper is to present some fixed point and coupled fixed point theorems for a nonlinear weakly C-contraction type mapping in metric and ordered metric spaces. Also, an example is given to support our results. Our results generalize several well-known results from the current literature. © 2011 Elsevier Ltd. Source
