Primary muscle hydatidosis is very rare, accounting for less than 1% of hydatid cyst locations, and the gluteus muscle location is exceptional. The objective of this study is to report an exceptional location of hydatid cyst of the gluteus muscle presented like a tumor in the buttock region. Magnetic resonance imaging (MRI) is helpful in diagnosis, it represents the best test for hydatid cysts of the soft parts. It is important to establish the diagnosis preoperatively in order to limit the risk of anaphylactic shock or dissemination in the event of puncture or accidental opening of the cyst during resection. The eradication of this disease is based on prophylaxis.

In this article, the effect of temperature on the photovoltaic parameters of mono-crystalline silicon Photovoltaic Panel is undertaken, using the Matlab environment with varying module temperature in the range 25°C - 60°C at constant solar irradiations 200 - 500 W/m2. The results show that the temperature has a significant impact on the various parameters of the photovoltaic panel and it controls the quality and performance of the solar panel. The photovoltaic parameters are the current of short circuit Isc, the open circuit voltage Vco, the form factor FF, the maximum power Pmax as well as efficiency. The relative change of these photovoltaic parameters with temperature is also evaluated in this article. A DS-100M solar panel has been used as reference model. The results show also that the open circuit voltage, maximum power, fill factor and efficiency decrease with temperature, but the short circuit current increa

In this paper, we study the quasi-coordinated search technique for a lost target assumed to move randomly on one of two disjoint lines according to a random walk motion, where there are two searchers beginning their search from the origin on the first line and other two searchers begin their search from the origin on the second line. But the motion of the two searchers on the first line is independent from the motion of the other two searchers on the second line. Here we introduce a model of search plan and investigate the expected value of the first meeting time between one of the searchers and the lost target. Also, we prove the existence of a search plan which minimizes the expected value of the first meeting time between one of the searchers and the target.

The aim of this study is to examine and present the results of the scientific examinations carried out on the ground layers with paint samples collected from the decorated surfaces of the wooden coffin dated back to the late period from Saqqara excavation that belonged to the Ministry of Antiquities. Many analytical methods were performed as optical microscopy, scanning electron microscopy coupled with energy-dispersive X-ray analysis （ESEM-EDX）, X-ray diffraction analysis as well as fourier transform infrared spectroscopy have been used to both characterise the inorganic composition and the binding media used. The analytical results showed that the materials composition and technique used to plaster applied on the wooden surface are in good agreement with the information gathered through the historical survey. The coffin was in bad and poor condition. There was cracking on the surface and in the structure, serious flaking, cupping of some pigments and serious damage in both the wooden support and gesso layer. Conservation treatment processes carried out included consolidation of lifting areas of the paint film, disturbing restoration materials, repair of cracks in the wooden support and a dry surface cleaning of the pigments.

Mobarak Raouf M. afifi Amani Qulali Emergency Department Prince Mansour Hospital Taif Kingdom of Saudi Arabia Academic Consultancy Board of Family and Community Medicine Program Taif Kingdom of Saudi Arabia Community Health Institute International Management-Health Services Inc. Indianapolis IN USA

Background: Increasing the number of qualified people, including school students who can play a significant role in first-aid (FA) and basic life support (BLS) arena is a public health demand. Aim: To assess the awareness of Saudi secondary school students regarding FA and BLS. Methodology: 360 male secondary school children in Taif, Saudi Arabia were surveyed. Results: The mean students’ age was 17.4 ± 1.21 years. The mean participants’ FA knowledge score was 64.8% ± 11%. Generally, trained students reported both better FA knowledge and skills than untrained counter-parts;for 79.6% trained-compared to 53.7% untrained-students recorded such score > 70% [χ2 (df 1) = 11.60, p 70%) [62.3% 2(df 1) = 5.90, p = 0.02] was. Trained students better deal with critical cases, bleeding and bodily injury compared to untrained peers [89.8% vs. 55.9%, χ2 (df 1) = 20.3, p 2 (df 1) = 11.62, p = 0.04;81.6% vs. 67.2%, χ2 (df 1) = 4.13, p = 0.04, respectively]. Only 37.2% of schools had FA incorporated in the education curriculum. Eventually, FA training and the presence of FA group were significant predictors for improved FA knowledge among students [odds ratio (OR) 3.35, 95% CI 1.60 - 7.06;OR 2.28, 95% CI 1.34 - 3.95, respectively). Conclusions: First-aid training is crucial to enhance school children’s FA skills and to thrust their contribution to health emergency control efforts. Incorporating FA training within the educational curriculum of Saudi schools is a step forward to disseminate FA message in the community.

Background: Shallow wells and boreholes are vital sources of potable water in Hargeisa. This water can be polluted by runoff, in particular during the rainy season, causing outbreaks of waterborne infections. Objectives: This research aimed at evaluating the microbial quality of shallow wells and boreholes water around Hargeisa, Somaliland. Methods: The total coliform and Escherichia coli count were done by using the membrane filtration method. Overall, 100 ml of each water sample was filtered via a 0.45 μm membrane filter, and then the filters were put on m-Endo agar plates that were incubated at 37°C for 24 to 48 hours. Results: The mean value of total coliform counts for the boreholes and shallow wells ranged from 1.288 × 103 to 8.8 × 103 CFU/100ml, while the mean value of total E. coli counts also ranged from 3.5 × 102 to 4.429 × 103 CFU/100ml. Results from this study have demonstrated that all water sources (Arabsiyo, Dararweyne, Darasalaam, Dabaraqas, and Jaleelo) don’t comply with the WHO guideline for drinking water. Results from the analysis of water samples of 28 wells demonstrated a significant correlation between total coliform and E. coli counts (P = 0.01). Therefore, this water is not fit for human consumption unless it is treated. Conclusion: This study has demonstrated that all results of both mean values of total coliform and E. coli counts from groundwater of selected shallow wells and boreholes were beyond WHO standards, so water from Arabsiyo, Jaleelo, Dabaraqas, Dararweyne, and Darasalaam requires treatment before human consumption.

Objective: To assess the antiangiogcnic activity of ***: Different fractions of fenugreek crude extracts were prepared and their antiangiogenic properties were assessed using the ex vivo rat aortic ring assay and in vivo chicken embryo chorioallantoic membrane(CAM) assay. They were investigated for their direct cytotoxic activity in the MCF7 cells using the MTT ***: The ethanol extract showed 100% inhibition of blood vessel outgrowth from primary tissue explants in the rat aortic ring assay at a concentration of 100μg/mL while the other extracts did not show significant antiangiogenic activity. The ethanol extract was therefore investigated at varying concentrations and exhibited a significant dose dependent effect. The CAM assay coincided with the results of the aortic ring assay as ethanol extract showed a significant inhibition of formation of new blood vessels. The extracts only showed anti-proliferative activity at the highest concentration of 400μg/mL towards MCF7 breast cancer cell lines in the MTT ***: Findings of the both assays confirmed that the ethanol extract inhibited vascularization significantly. Further studies on the ethanol extract would be beneficial in isolating the active ingredient responsible for the inhibition.
