Some recurrence relations, generating relations and integral representations are derived for that new extension.</p> Salem Saleh Barahmah Copyright (c) 2020 Salem Saleh Barahmah https://creativecommons.org/licenses/by-nc/4.0 2020-09-30 2020-09-30 1 3 120 127 10.47372/ejua-ba.2020.3.33 INVESTIGATION OF MERCURY AND TITANIUM CONTENTS IN SKIN WHITENING CREAMS COMMONLY USED IN YEMEN BY ICP-MS https://ejua.net/index.php/EJUA-BA/article/view/34 <p style="text-align: justify;">In this study, ten (10) samples of skin-whitening creams were analyzed for determination of mercury and titanium. The samples were collected from various retail shops, pharmacies and beauty aid stores in the local market of Yemen. Levels of mercury and titanium in creams were determined using Inductive Coupled Plasma with Mass Spectrometry (ICP-MS). The concentration of mercury in the creams ranged from below 0.0167 to 47151 μg/g and that of titanium ranged from below 0.0083 to 59.442 μg/g. Fifty percent (50%) of creams samples for mercury had concentrations more than Maximum Permissible Limits by specifications of the US Food and Drug Administration’s, (USFDA), German and Canada (Maximum Acceptable Limit of 1μg/g). The use of such creams may lead to health hazards. Therefore, it is recommended that all skin whitening creams should be checked for mercury levels and other toxic metals before marketing. Further research to better understand the sources of mercury and other toxic metals in whitening creams and other cosmetic products is recommended.</p> Shaif Mohamed Kasem Saleh Omeima A.

The aims of this study are to explore the natural plant species of one of the Important Plant areas of Arabian Peninsula and to evaluate the chance to be a protected area. 61 sample sites covering the whole ecological zones haven been conducted. 135 plant species are found, in which 3 plant species were endemic, 7 near endemic, 29 regional endemic. The study revealed also three vegetation communities with 7 vegetation associations (vegetation types). Vegetation dominated by <em>Ficus cordata, F. sycomorus, Salvadora persica Tamarix aphylla </em>and<em> Ziziphus spina-christ</em>i were found on main wadis. Vegetation communities dominated by <em>Acacia asak, Anisotes trisulcus, Jatropha variegate </em>and <em>Zygocarpum yemenense </em>were found on rocky slopes and stony plateau.</p> Abdul Wali Ahmed Al-Khulaidi Abdul Habib Al-Qadasi Othman Saad Saeed Al-Hawshabi Copyright (c) 2020 Abdul Wali Ahmed Al-Khulaidi, Abdul Habib Al-Qadasi, Othman Saad Saeed Al-Hawshabi https://creativecommons.org/licenses/by-nc/4.0 2020-09-30 2020-09-30 1 3 135 150 10.47372/ejua-ba.2020.3.36 ESTMAITION OF HEAVY METALS IN THE GROUNDWATER OF SELECTED AREAS FROM AL-DHALIA DISTRICT, AL-DHALIA GOV., YEMEN https://ejua.net/index.php/EJUA-BA/article/view/37 <p style="text-align: justify;">In this research, the level of heavy metals Cadmium (Cd), Chromium (Cr), Copper (Cu), Iron (Fe), Manganese (Mn), Lead (Pb) and Zinc (Zn) in groundwater in selected areas in the region of Al-Dhalia district, Al-Dhalia Governorate, Yemen.&nbsp; Sixteen groundwater samples were collected from the study area included 9 artesian wells samples and 7 of hand-dug wells, and analyzed for the presence of heavy metals using Atomic Absorption Spectrophotometer (AAS). The results of the analysis showed that the concentrations of Pb, Mn and Cu in most of the studied samples have exceeded the Yemeni and WHO standards for drinking water, while the concentrations of Fe, Cd, Cr and Zn in most of the studied samples were low and fall within the optimum specifications for local and WHO drinking water.</p> Shaif Mohamed Kasem Saleh Mohamed Muthana Taher Bassem O.

In wartime, civilians have became a direct target and accounted for one-half to two-thirds of the casualties. We aimed to highlight the incidence and pattern of thoracic injury and its outcomes management among civilians during the war in Aden.&nbsp; This retrospective study was based on the data were prospectively recorded in Medical Registry. There were 84 civilian casualties identified during the study period. Of those, 97.6% of casualties were males and 2.4% were females. The overall mean age was 30.8 ± 9.8 years (range: 10 – 65 years). Of those, 73.8% of casualties were produced by rifle bullets, while 26.2% of casualties were due to fragmentation weapons. Hemopneumothorax was the most common injury patterns. Abdomen injury was the most common associated injuries. Of those, 91.7% of casualties were treated with chest tube insertion alone. Thoracotomy was performed for 7.1% of casualties. The overall complications were 54.8%. Wound infection was the most frequent complications. The overall mortality rate was 3.6%. The overall mean hospital stay was 8.3 ± 5.9 days. We concluded that chest drain is best option for treatment the majority penetrating chest wounds.</p> Mohamed Hasson Salem Gamal M.

The longest and largest erythrocytes and their nucleus were observed in the smears of C.&nbsp; <em>c.</em> <em>calyptratus</em>, while the narrowest and smallest in <em>A. adramitanus</em>. In terms of the studied species, the nucleus and erythrocyte sizes were found to be correlated. No significant difference between two species lizard’s in erythrocyte count was determined. The relationship between the raw erythrocyte measurements and erythrocyte length was determined as positive correlation.</p> Yaser H. A. Obady Ola A. A. Alareeqi Copyright (c) 2020 Yaser H. A.
