The main purpose of RESCAP-MED is to enhance the non-communicable diseases (NCDs) research landscape in southern and eastern Mediterranean countries by (a) strengthening capacity in a set of disciplines most relevant to improving public health and reducing health inequalities, and (b) enhancing networking, cooperation, and collaboration between researchers in the Mediterranean region. The main concept for achieving this purpose and making it sustainable is: 1 the creation of a Mediterranean regional network for NCD researchers; 2 the establishment of a competitive, funded fellowship programme linked to this research network. This proposal aims to enhance and, where needed, build research capacity in the region for health, its social and environmental determinants and their complex interactions, in order to inform policy development and implementation. We concentrate on the immense challenge posed to the health systems and economies of the region by the increasing burden of NCDs. We focus on strengthening the disciplinary capacity necessary to explain the social and environmental factors causing the rise in NCDs, and necessary to identify achievable policy outcomes and interventions. We prioritise five disciplines in this action: epidemiology, health economics, environmental health, medical anthropology, and health policy evaluation. These actions would create new institutional possibilities for the future, and are made more achievable because this proposal develops out of an existing FP7-funded research collaboration (MedCHAMPS, Grant number 223075) in several countries of the region, each of which is a partner in RESCAP-MED. It thus builds directly on established and ongoing personal and institutional relationships, and the emerging evidence from MedCHAMPS. This consortium brings together 11 partners: ten academic partners and one international organisation (WHO-EMRO).

This paper investigates the performance of solar thermal system for powering irrigation pump. It also summarizes the recent developments of solar thermal power systems. Furthermore, it updates the literature about the recent findings of thermal solar power system and presents different methodologies of enhancing the solar energy conversion system. The solar thermal irrigation pump uses steam Rankine cycles SRC integrated with parabolic trough collector PTC. The selected site is located in the northern part of Jordan. Simulation models are built to assess the performance of solar thermal irrigation system. The simulation models are built by means of mass and energy balances applied to every component of the system. The model simulates the hourly thermal behavior of all system components. The effect of key operating variables on the system performance is examined. Simulation results show that there is an optimum values for mass flow rate where maximum power out can be obtained. The average daily overall efficiency ranges between 10 to 13% during summer time. The optimal daily average overall efficiency reaches 18%. Results show that the concentration ratio has negligible effect on the overall system performance. It is found that using PTC of area of 526 m2 with SRC is reliable system producing above 30 kW during summer time. Economic analysis reveals that the solar energy cost is $0.075/kWh. Furthermore, this paper presents design optimization so that STWP can achieve higher reliable continuous operation with system components. © 2015 Elsevier Ltd. All rights reserved.

Large windows and highly glazed façades have been increasingly used in new buildings, allowing access to daylight, solar gain and external view. Sunrays passing through non-shaded windows and glazed facades significantly increases the air temperature in summer, especially in hot climates such as in Jordan. This negatively affects thermal comfort, increases the cooling load and becomes a source of glare, which harms the visual environment. The current research examined the effect of using shading devices on air temperature, visual environment and users' interaction in offices facing south-west façade at Jordan University of Science and Technology (JUST). Generally, shading devices are used to protect inner spaces from direct solar gain through openings, windows and large glazed surfaces. In such orientation, windows require special considerations to control solar gain, improve the visual environment and reduce glare. The research used real-time experiments and computer simulations to study how the shading devices will work in controlling air temperature and improving illuminance level. Three fixed shading devices (vertical fins, diagonal fins and egg crate) were installed in three identical offices in two stages: the first stage used temporary material while second one used improved design and permanent materials. Thereafter, the air temperature, illuminance level, thermal and visual environment were monitored and compared to non-shaded office. Computer simulations: IES/SunCast and Radiance were used to study solar and daylight distribution over the offices' surfaces around the year. The results showed that the temperature in offices with shading devices compared to the office without shading devices was reduced to acceptable level. Visual environment was improved by controlling the illuminance level, improving uniformity and eliminating glare. Offices with diagonal fins and egg crate shading devices performed better compared to the office with vertical fins and the base case. © 2014 Elsevier Ltd.

With increasing world energy demands, the search for an environmentally-friendly fuel is a must. Hydrogen is a fuel that is energy-efficient and clean, and considered by many as the perfect fuel. The problem arises when it comes to safety considerations. It does not have a good reputation because of some unfortunate accidents during history. In this work the safety of hydrogen during production, transmission and use is reviewed. Hydrogen safety issues are mainly discussed in relation to its ignition and combustion characteristics namely: wide flammability range detonation level, low ignition energy, relatively high flame velocity, rapid diffusion and buoyancy, in addition to it its characteristics in the liquid phase. Hydrogen is the lightest gas (14 times lighter than air), highly flammable, odorless, and burns with a colorless flame. When used as a fuel, it supplies more energy per unit mass, than the popular fuels used today. In producing hydrogen, there are many processes, each one with its hazards, but these are relatively less weighed against hydrogen having the highest energy-carrying abilities. In storing, transmission and using of hydrogen, the main hazard is in its leaking, causing a fire to start. To detect when a leak happens, reliable and economic sensors should be used. High degree of safety, depending on hydrogen properties, is essential in any relevant design, to accelerate toward hydrogen economy. Copyright © 2013, Hydrogen Energy Publications, LLC.

Object-oriented metrics have been validated empirically as measures of design complexity. These metrics can be used to mitigate potential problems in the software complexity. However, there are few studies that were conducted to formulate the guidelines, represented as threshold values, to interpret the complexity of the software design using metrics. Classes can be clustered into low and high risk levels using threshold values. In this paper, we use a statistical model, derived from the logistic regression, to identify threshold values for the Chidamber and Kemerer (CK) metrics. The methodology is validated empirically on a large open-source systemthe-the Eclipse project. The empirical results indicate that the CK metrics have threshold effects at various risk levels. We have validated the use of these thresholds on the next release of the Eclipse project-Version 2.1-using decision trees. In addition, the selected threshold values were more accurate than those were selected based on either intuitive perspectives or on data distribution parameters. Furthermore, the proposed model can be exploited to find the risk level for an arbitrary threshold value. These findings suggest that there is a relationship between risk levels and object-oriented metrics and that risk levels can be used to identify threshold effects. © 2006 IEEE.

We performed first-principles spin polarized computations to study the structural, electronic, and magnetic properties of diluted magnetic semiconductors (DMSs) based on wide band-gap wurtzite ZnO and GaN semiconductors doped with transition magnetic metals. The main feature of the resulting DMSs is the strong ferromagnetic spin-spin interaction. We characterzie the gaint Zeeman effect observed experimentally upon applying an external magnetic field using pure quantum mechanical based technique. We found that this effect increases substantially with Fe content in GaN:Fe3+ DMS system at an external magnetic field of 10 T. We found that the magnetization of ZnO and GaN doped with Mn3+, Mn2+, Co2+ and Fe3+ is well described by the Brillouin function. The p-d exchange integrals α and β for these transition magnetic ions doped wide band-gap DMSs have been determined accurately. They exhibit positive value for Ga 1-xMnxN and Ga1-xFexN and Zn 1-xCoxO indicating ferromagnetic interaction. Furthermore, Magnetocrystalline anistropy energy (MAE) and perpinduclar magnetocrystalline anistropy (PMCA) of ZnO:Mn3+, GaN:Fe3+, and ZnO: Co 2+ diluted systems for transition ion concentration fixed at x=0.125 have been calculated and discussed based on spin-dependent band structure and density of states calculations. We found a robustness of PMCA with respect to lattice strain is remarakable for all the three DMSs systems studied. We found that ZnO:Mn3+ DMS is a good spin injector. © 2014 Elsevier B.V.
