In this study, Nonlinear Autoregressive Exogenous (NARX) model was used to predict hourly solar radiation in Amman, Jordan. This model was constructed and tested using MATLAB software. The performance of NARX model was examined and compared with different training algorithms. Meteorological data for the years from 2004 to 2007 were used to train the Artificial Neural Network (ANN) while the data of the year 2008 were used to test it. The Marquardt-Levenberg learning algorithm with a minimum root mean squared error (RMSE) and maximum coefficient of determination (R) was found as the best in both training and validation period when applied in NARX model. © 2013 Jordan Journal of Mechanical and Industrial Engineering.

The overarching aim of the J-ERAcenter is: To contribute to the effective integration of Jordan into ERA, through building the National Centre for Research and Development (NCRD) organisational, strategic and human capacities to actively participate in European S&T partnerships and execute large-scale projects in the key area of Renewable Energy, with a view to creating a centre of excellence within Jordan and actively promoting further dissemination and replication in the region. Specifically J-ERAcenter aims: To build capacities in international R&D cooperation and EU project management, by providing targeted training to NCRD staff and researchers and enable them to replicate the knowledge benefiting a wider target group of researchers in Jordan. To strengthen direct links between research teams of NCRD and their EU counterparts and initiate joint R&D initiatives in the area of Renewable Energy, through a series of networking/partnering events and facilitating mobility of researchers. To ensure firm and sustainable implementation of the enhanced capacities at NCRD with a view to promoting the centres international competitiveness and improve its response to socio-economic challenges; through implementing specific internationalisation, visibility, IP and competitiveness strategies (for enhancement of the institutional development strategy), and the implementation of a R&D Cooperation Unit. To promote the visibility and impact of this pilot action, positioning NCRD as a Centre of Excellence for EU-Jordan RTD cooperation, via targeted multiplication and dissemination actions (networking events, info-days, seminars). Jordans leading research centre in Renewable Energy is the main beneficiary and coordinator, due to its high multiplier potential to act as catalyst for integration into ERA, and the importance of RE to both regions. The consortium includes EU partners with complementary expertise in the scientific field (UASTV, UMU) and EU project management (UA).

The growing economies in the southern and eastern Mediterranean area increasingly need affordable and efficient energy and water for sustainable development. Hybrid solar/fossil thermal power plants with combined sea water desalination based on concentrating solar power technology (CSP) offer a unique, cost efficient solution to the growing energy and water demand. Hybrid solar/fossil operation offers a smooth transition from the fossil fuel to a solar economy and provides firm power capacity to the grid with up to 8000 full load operating hours per year. The main objective of the MED CSD project is the assessment of the technico-economic potential of CSP for electricity and desalination in Mediterranean region, particularly the Mediterranean Partners Countries (MPCs) (WP3) based on a technology review and considering the results of past and on-going studies and projects (Aqaba project as a reference) (WP1) and attained through the realization of feasibility studies in Mediterranean countries and an impact assessment analysis (WP2). WP1 is the selection of CSP and desalination configurations suitable for application in the Southern and Eastern Mediterranean region, using information on state of the art of CSP and desalination, specifically engineering performed for Aqaba hybrid CSP desalination plant, and taking into consideration the specific situation and needs where the feasibility studies will be performed. In WP2, a generic feasibility study will be defined and applied to Algeria, Italian Island, Egypt, Morocco and PNA including an impact assessment analysis for a broad dissemination. WP3 will relate to the assessment of the technico-economic potential of CSP for electricity and desalination in Mediterranean Partner Countries (MPCs). It will be followed by an Action Plan and dissemination of the results (WP4).

The effect of using different concentrations of aqueous nanosuspensions of clay minerals (1%, 1.5%, and 2%) offered at different periods of time (one time per one or two weeks) compared with tap-water with and without antibiotics on growth performance and some selected antibody titer was studied. The experiment lasted from 1 to 36 days of age. The statistical findings of the experiment prove that aqueous nanosuspension 1% offered one time per two weeks significantly improved feed conversion ratio (FCR). Meanwhile, aqueous nanosuspension 2% offered one time per two weeks significantly gave the same effect on live body weight (LBW) and body weight gain (BWG) as did antibiotics. Concerning the findings that pertain to immunity, antibody titer against the most infectious diseases [Newcastle (ND), infectious bronchitis (IB), and infectious bursal disease (IBD)] were significantly improved by offering aqueous nanosuspension 1.5% offered one time per one and two weeks, and aqueous nanosuspension 1% offered one time per one week, respectively.

Studies on the germination of charophyte oospores in lake populations have revealed that oospores germinate rarely and in small numbers. Despite this, perennial populations of charophytes continue to exist in deep lakes in Poland. We examined the reproductive potential of vegetative parts of charophyte thallus to determine how these might contribute to charophyte persistence. Thallus fragments of Chara rudis can form a propagule bank and function as vegetative propagules that give rise to new thalli (ramets) in Polish lakes. Experimental results show that naturally produced thallus fragments are present on the benthic sediment surface and can initiate new growth, resulting in new plants. Multinode fragments and apical fragments produce the largest number of ramets. Thallus fragments from the deep zones (> 5 m) produce the more ramets than those from shallower areas. Thus, thallus fragments play a significant role in population persistence in the deep areas of the lake. Given the reported low germination rates of oospores from perennial populations, it is likely that vegetative reproduction, via thallus fragments, has an important role in population maintenance.
