The main objective of this work is to design an optimal—efficient economic power renewable energy system that feeds the required electric load of a small scale brackish reverse osmosis desalination unit and a tourism motel located in Hurghada, Egypt. Four renewable energy power systems are presented in this paper to select the most optimum one of them. These suggested renewable energy systems are PV-wind hybrid system, stand-alone wind system, stand-alone photovoltaic system and PV-wind-fuel cell hybrid system. The sizing, optimization and economic estimation of the proposed systems were performed using HOMER software. HOMER solves the optimization problem to minimize the global cost and provides the optimum wind turbine, PV, battery and fuel cell ratings. In addition, a comparison between the four different suggested power system configurations is illustrated in details. PV-wind hybrid system realized the lowest net present cost and levelized cost of energy. Also, this system was able to provide energy approximately all the day. The battery state of charge varies between 83% and 99% and it was found that, the PV-wind hybrid system is more suitable than the others for the selected site and the suggested electrical load.

OBJECTIVES: To determine the epidemiological features of pulmonary tuberculosis in the region of Gharb-Chrarda-Beni-Hssen in Morocco. METHODS: This is a retrospective study of pulmonary tuberculosis cases, diagnosed and treated at the regional diagnostic center of tuberculosis and respiratory diseases (RDCTRD) in Kenitra between January 2010 and December 2011. RESULTS: During the study period, there were 456 cases diagnosed with pulmonary tuberculosis at the RDCTRD, accounting for 51.3% of all tuberculosis cases reported during this period. More than two-thirds were men (69%), with a male-female ratio of 2.22 and 3.3% of cases were children under the age of 15 years. The average age of the patients was 37.07 ± 0.78 years. The average body weight at diagnosis of tuberculosis was 56.20 ± 0.55 kg for all patients. According to the results, 89% of pulmonary tuberculosis cases were microscopically positive. The majority of patients (80.3%) showed signs of tuberculous impregnation. Nearly three-quarters of these cases (71%) were smokers, 21% were cannabis addicts and 7% were alcoholics. Among the 427 cases for whom the outcome was known, 3 (0.7%) of them died. CONCLUSION: Tuberculosis can be controlled by preventing transmission and infection, by stopping the progression from latent infection to active tuberculosis, and by treating active disease.

This paper aimed to study the effects of natural polysaccharide (gum arabic, GA) on the formation of vaterite calcium carbonate and its stability in aqueous solution. Gum arabic is a macromolecule that has a high molecular weight and is amphoteric in character. A 0, 2.5, 5 or 10 ml of GA solution (30%) was added to the calcium chloride solution with various initial concentrations to prepare the vaterite calcium carbonate. The calcium carbonate particles were characterized using FTIR, XRD, SEM, TEM and DSC-TG as well as calculation of phase contents. The results of XRD and FTIR analysis were showing that the presence of GA during the precipitation changes the behavior of calcium carbonate to form vaterite until at lower dose used. In addition, the molar content of vaterite increased at the expense of content of calcite with increasing the GA dose. There are slightly improvements in the vaterite content by increasing the initial concentration. The formed vaterite calcium carbonates composed of aggregates as broccoli-like or spherical shape and with particle size 1.6 - 2.5 μm in diameter. TEM images showed that these aggregates composed of the sub spherical unit with diameter 15 - 30 nm. The thermal behavior of prepared vaterite was conformed the mineral composition of these phases. The prepared calcium carbonate, which is formed in the presence of different doses of gum, has a stability in the aqueous solutions at different temperatures, as the analyzes indicated that a very small percentage of the vaterite were converted to calcite. The gum arabic prevented or depressed the transformation of vaterite to calcite through capped the surface of particles, i.e. it is more effective in stabilizing the vaterite phase with increasing in initial concentration and time.

Background: Early detection of cerebral infarction (CI) by home acupuncturists might be helpful in reducing stroke mortality. We compared vital signs of patients who developed CI and those who did not to ascertain if blood pressure balance is a useful marker for the early detection of CI and for distinguishing cases with potentially effective/ineffective acupuncture treatment. Methods: In this retrospective study, vital signs such as body temperature, pulse, and blood pressure, were simultaneously obtained from the right and left arms of patients who received weekly acupuncture treatment. We focused on the differences between values obtained from the right and left arms (the balance) and compared the values of patients who developed CI [CI (+)] (n = 18) and those of age-/gender-matched patients who did not [CI (−)] (n = 18). Results: Left/right blood pressure was significantly more unbalanced in the CI (+) group than in the CI (−) group, especially immediately before the onset of CI. Moreover, all CIs occurred on the side with a lower blood pressure. Discussion and Conclusions: Blood pressure balance might aid in the early detection of CI and to determine whether treatment with traditional or modern medicine is more appropriate. Acupuncture may thus help maintain patients’ quality of life.

Greenhouses are used for the main purpose of improving the environmental conditions in which plants are grown. There are many parameters can affect the growing of plants inside greenhouse, such as air temperature and relative humidity. The adjustment of these parameters is achieved by selecting appropriate control actions. This work proposes a controlling technique for greenhouse indoor temperature and relative humidity. The proposed greenhouse cooling system temperature controller is designed to adjust the air volume flow rate in pad-fan cooling system to fix the greenhouse indoor temperature at 20?C and 70% relative humidity. The designed control technique is realized to ensure the required and continuous operation of the greenhouse. Moreover, this work present, a complete mathematical modeling and simulation of cooling system is introduced. In addition, a computer model based on MATLAB SIMULINK software has been used to predict the temperature and relative humidity profiles inside the greenhouse. The results are realized the requirements of the greenhouse cooling system environment.

A two-year study was carried out at the Agricultural Experiments and Research Station, Faculty of Agriculture, Cairo University, Giza, Egypt, during 2015/2016 and 2016/2017 seasons to evaluate seed yield and quality of two faba bean cultivars to different rates of amino acids compounds under narrow and wide ridges. Two faba bean cultivars Sakha 1 and Masr 3 were grown in two ridge widths 60 and 120 cm and received five rates of amino acids compounds (Power mix at rates 1.5 cm⋅L−1 “Pm1” and 3.0 cm⋅L−1 “Pm2”, Super mix at rates of 3.5 cm⋅L−1 “Sm1” and 7.0 cm⋅L−1 “Sm2”, as well as, water only “control treatment”). The treatments laid out in a split split plot distribution in randomized complete blocks design in three replications were used. Ridge width was randomly assigned to the main plots, faba bean cultivars were allocated in sub-plots and amino acids compounds were allocated in sub sub-plots. Shoot chemical composition and photosynthesis pigments, as well as, chemical composition in seed traits of faba bean were tested in the laboratories of Plant Physiology Section, Agricultural Botany Department, Faculty of Agriculture, Cairo University, Giza, Egypt. Wide ridge had higher nitrogen (N), phosphorus (P), potassium (K), total sugars and total free amino acids concentrations in faba bean shoot and seeds in addition to chlorophyll a (Chl a) and chlorophyll b (Chl b) in faba bean shoot, as well as, most seed yield attributes than those of the narrow one. Faba bean cultivar Sakha 1 had higher values of seed yield, yield attributes and quality than Masr 3 that achieved higher seed antioxidants. Also, amino acids compounds affected significantly all studied traits of faba bean plants. Pm2 recorded the highest values of chemical composition in faba bean shoot and seeds. Moreover, Pm2 gave the highest seed yield and yield attributes compared to others. The interaction between ridge width and faba bean cultivar was significant
