A. AlKelly Ibrahim G. H. Loqman Hassan T. Al-Ahsab <p style="text-align: justify;">Focus shaping of cylindrically polarized vortex beams (CPVBs) by linear axicon is studied theoretically. Vector diffraction theory has been used to derive the expressions of the light field in the focal region. It is shown that a different intensity distribution in the focal region can be obtained by adjusting the topological charge, the polarization rotation angle and the numerical aperture maximal angle. A focal spot, a dark channel and a flat-topped shapes are formed by choosing proper values of parameters. A controllable polarization state of dark channel is obtained. The different focal region shapes may find wide applications such as material processing and optical tweezers.</p> 2021-12-31T00:00:00+00:00 Copyright (c) 2021 A. A. AlKelly, Ibrahim G. H. Loqman, Hassan T. Al-Ahsab THE PROTECTIVE AND THERAPEUTIC EFFECT OF CORN SILK EXTRACT ON UROLITHIATIC AND HYPERTENSIVE RATS INDUCED BY ETHYLENE GLYCOL 2022-01-04T17:06:39+00:00 Abdulrhman A. Almadiy Afrah Ali Alasbahy Hussein S. Gumaih E. S. Nasr Maher A. Al-Maktari <p style="text-align: justify;">Renal stone is one of the most problems worldwide. They are affected by different factors such as environmental effectors such as nutrient as well as family history. Corn silk (CS) used as antiurolythiasis. This study investigated the impact of corn silk extract as the management of renal stone formation, hypertension, and hepatoprotective. This work has been carried out on rats at Faculty of science Sana’a University, University of Science, and Technology Laboratories. Twenty-four male albino rats with weighing range between (200 g to 250g) were taken. They were divided in four groups (each group consists of 6animals). The first group of rats took normal diet and named as negative control (Co) whereas, the second group took normal diet with ethylene glycol (EG) (0.75%) and 1% ammonium chloride (AC) for 28 days and serve as positive control (Po). The third and fourth groups took the same substances as inPo group with 200 mg/kg and 400 mg/kg of corn silk (CS) for 28 days respectively.<br>Blood samples were collected from rats on last day of the experiment. All the tested samples showed a significant antioxidant DPPH radical scavenging activity and a notifiable decrease in serum aldosterone hormone, angiotensin comforting enzyme urea and creatinine levels comparedto positive control. Shown to significantly increased AST, ALT, and LDH in comparison to the urolithiatic group and near of normal group.<br>In conclusion, the present study emphasizes the safe herbal remedies of CS as anti-hypertensive and antioxidants, as well as antiurolithiatic and hepatoprotective.</p> 2021-12-31T00:00:00+00:00 Copyright (c) 2021 Abdulrhman A.

Al-Maktari INDOOR RADON-222 CONCENTRATION MEASUREMENTS AT FACULTY OF EDUCATION, YAFEA, ADEN UNIVERSITY, YEMEN, USING CR-39 NUCLEAR TRACK DETECTOR 2022-01-04T17:06:37+00:00 Anwar Khadher Mohammed Mokhtar Salim Saleh Al_Salimi M. I. Ahmed <p style="text-align: justify;">In this study, the activity concentration of indoor radon-222, annual effective dose, exhalation rate of radon, and relative risk of lung cancer are reported for different indoor buildings (students' dorms, teachers' dorms, offices, laboratories, library, lecture halls, and materials store) in Faculty of Education, Yafea, Aden University, Yemen. Sealed-can technique based on CR-39 nuclear tracks detector was distributed to radon gas survey. Twenty six radon detectors were mounted in seven buildings. The Radon measurements were performed for 90 days between December 2020 and March 2021. The results showed that the radon concentration ranges from 23,18 Bq m<sup>-3</sup> to 66.49 Bq m<sup>-3</sup> with an average value 35.86 Bq m<sup>-3</sup>, the annual effective dose ranges from 0.6 mSv y<sup>-1</sup> to 1.639 mSv y<sup>-1</sup> with an average value 0.979 mSv y<sup>-1</sup>, the exhalation rate ranges from 10.03 m Bq m<sup>-2</sup> h<sup>-1</sup> to 28.50 mBq m<sup>-2 </sup>h<sup>-1</sup> with an average value 15.68 mBq m<sup>-2 </sup>h<sup>-1</sup> and relative risk of lung cancer ranges from 1.02 to 1.06 with an average value 1.03. A strong correlation coefficient has been observed between radon concentration and radon exhalation rate. All of the values revealed in the study were of nominal state (that is less than allowed global values) and thus have no risk for the population living in these buildings.</p> 2021-12-31T00:00:00+00:00 Copyright (c) 2021 Anwar Khadher Mohammed, Mokhtar Salim Saleh Al_Salimi, M. I. Ahmed THE PREVALENCE OF VULVOVAGINAL CANDIDIASIS (VVC) AMONG WOMEN SUFFERING VAGINITIS ATTENDED A PRIVATE GYNECOLOGICAL CLINIC, ADEN-YEMEN 2022-01-05T17:49:44+00:00 Adel Jumaan Binsaad Nazeh Al-Abd <p style="text-align: justify;">The study was carried out to determine the prevalence of vulvovaginal candidiasis among women suffering vaginitis. This prospective cross-sectional study was conducted among 120 women between the age of 15 to 45 years (mean age 39 years), attended a private gynecological clinic in Aden with symptoms of vaginitis between January and June 2019. A questionnaire was used to obtain information on the participants’ sociodemographic data and medical history. Direct microscopic examination (10% KOH), culture on SDA, germ tube test and gram staining were used to determine the prevalence of vulvovaginal candidiasis and to differentiate between <em>C.albicans</em> and <em>non-albicans</em> species. Out of 120 women, 25 (20.8%) were diagnosed with vulvovaginal candidiasis (VVC) and 95 (79.2%) with non-candidal vaginitis.<em> C.albicans</em> was the most prevalent with a prevalence rate of 17.5%. Although not statistically significant, vulvovaginal candidiasis tended to be more prevalent among women with 25-34 years. No statistically significant association between the prevalence of vulvovaginal candidiasis and educational level and marital status. Vulvovaginal candidiasis (VVC) was slightly high in Aden and<em> Candida albicans</em> was the most common causative agent of VVC. In the clinical diagnosis of VVC, both clinical criteria and microbiological tests must be used. Further study is needed to find out the prevalence of RVVC among women in the Aden governorate.</p> 2021-12-31T00:00:00+00:00 Copyright (c) 2021 Adel Jumaan Binsaad, Nazeh Al-Abd EFFECT OF MORINGA AND OLIVE LEAVES POWDER CONSUMPTION ON HYPERGLYCEMIC STATE IN TYPE 2 DIABETES MELLITUS (A PILOT STUDY) 2022-01-12T20:36:10+00:00 Taha Abdo Ali Naji <p style="text-align: justify;">Study showed effects of Moringa oleifera (MO) and Olea europaea (OE) leaves powder on lowering blood sugar levels in diabetes patients. The aims of this study were to determine the effect of MO and OE leaves powder on blood glucose control in therapy type 2 diabetes mellitus (T2DM).<br>Diabetic patients (160 with diet-controlled type 2 diabetes and 250 non-diabetic) healthy volunteers were asked to fast for 13 hours on three occasions. Blood glucose was measured before and after eating 100g of white carbohydrates (bread) (at 30, 60, 90, 120, 150 and 180 minutes). On their second and third study visits, they were given 1g and 2g respectively, of Moringa oleifera and Olea europaea leaves powder for 30 minutes after eating the bread.<br>Ingestion of Moringa oleifera (MO) and Olea europaea (OE) leaves powder had no effect on blood glucose in non-diabetic participants, but in diabetic patients, Moringa oleifera and Olea europaea powder reduced post-prandial glycaemia in diabetic patients. A larger study is needed to define the optimal dose and to assess whether this translates into longer-term benefits.</p> 2021-12-31T00:00:00+00:00 Copyright (c) 2021 Taha Abdo Ali Naji EFFECT OF ONE-DAY-OLD CHICK'S WEIGHT ON GROWTH CHARACTERISTICS AND CARCASS CUTS OF BROILERS CHICK'S ROSS 2022-01-04T17:06:34+00:00 Mazen Nasser Ali <p style="text-align: justify;">The experiment was conducted in the barn of the Department of Animal Production, Nasser College for Agricultural Sciences Lahij Governorate, during the period 28/1/2020 to 2/3/2020. The study targeted two weight categories of chicks. In the experiment, 90 unsexed one-day-old Ross chicks were used. These chicks were divided into. Two treatments based on weight. The first treatment T1, 45 chicks weighing 39-40 g, and the second treatment T2 also contained 45 chicks weighing 44-45 g. The chicks were divided into two groups that are, three replicates with 15 chicks for each replicate. T2 on treatment T1 and the weights were 15176.66,, 1643.33, 1193,33g for both body weight and carcass weight, respectively, while the results did not show any significant superiority in the amount of feed consumed, feed conversion factor, and dressing ratio. Treatment T2 showed a weight superiority over treatment T1 in the weight of the chest, thighs, back, and neck. The weights were 391, 310, 203.33, 78 g and 433, 316.67, 8, 225, 86.67 g, for treatment T1 and T2 respectively, and this increase did not reach the significant level.</p> 2021-12-31T00:00:00+00:00 Copyright (c) 2021 Mazen Nasser Ali
