Abstract

The present study was done to determine and evaluate the effect of X-ray irradiation on the testicular tissue of rabbits those were exposed for a long time. Ten male rabbits, 8-9 months old and their weight approximately two kg. Rabbits were exposed to X-ray irradiation for two months/ twice daily. Blood parameters and testosterone hormone were measured within 20th, 40th, and 60th days after exposure. Orchictomy were done by surgical methods after 60th days for histopathological examination. The results revealed highly changes in testis such as atrophy, hyper atrophy, blood vessel congestion and suppression of spermatogenesis, blood parameter also changed and testosterone levels reach to zero at 60th days after exposure. In concluding that the persistence of X-ray exposure caused deterioration and passive effects on testicular tissue and other organs of rabbits.

Abstract

chest X-ray images considered an important test to diagnosis a several of chest diseases, it's the most commonly requested examination in any radiology department in spite of various technological advances in the field of radiology, however explanation of chest X-ray image is a complex task is because this images is tending to noise , low contrast , blurring and unwanted information hindering the analysis of the real problems in chest human being structures, this complexities associated with X-ray images make it difficult to analyze them in an effective way. In this paper, we apply anew algorithm to enhance chest X-ray digital images and thus enhance the diagnosis of specific diseases through the application of a several operations including intensification of the basic features of the images, as well as color enhancement based on applying a number of experiment equations and change the values of the main coefficient for this equations , the medical image that has been conducting all operations onto belong to Hydatid Cysts Parasite diseases in lung . when we observed the resulting images we manifestly noting the Hydatid Cyst inside the right lobe of the lung patient in the upper part of which more clearly than is the case in the original image, and this is a good indicator of the success of the proposed algorithm to enhancing the diagnosis.

تعتبر صور الأشعة السينية الصدرية اختباراً مهما لتشخيص العديد من الأمراض الصدرية , حيث تمثل الفحص الأكثر طلبا عادة في أي قسم للأشعة على الرغم من تنوع التقدم التكنولوجي في مجال الطب الإشعاعي. غير أن شرح صورة الأشعة السينية الصدرية يعد مهمة معقدة وذلك لكون هذه الصور تميل إلى الضوضاء, انخفاض في التباين, الضبابية و احتوائها على المعلومات غير المرغوب فيها والتي تعيق تحليل المشاكل الحقيقية في بنية الصدر للانسان , هذه التعقيدات المرتبطة بصور الأشعة السينية تجعل من الصعب تحليلها بطريقة فعالة.في هذا البحث قمنا بتطبيق خوارزمية جديدة لتحسين صور الأشعة السينية الصدرية الطبية وبالتالي تحسين تشخيص أمراض محددة من خلال تطبيق العديد من العمليات بما في ذلك تكثيف السمات الأساسية للصور, وكذلك تحسين اللون بالاعتماد على كل من تطبيق عدد من المعادلات التجريبية وتغيير قيم المعاملات الرئيسية لهذه المعادلات,الصورة الطبية التي تم أجراء كافة العمليات عليها تخص مرض الأكياس المائية المتواجد في الرئة. وعند ملاحظتنا للصور الناتجة يتبن لنا بوضوح رؤية الكيس المائي داخل الفص الأيمن لرئة المريض في الجزء العلوي منها بصورة أوضح بكثير مما هو في الصورة الأصلية, و يعد هذا مؤشرا جيدا لنجاح الخوارزمية المقترحة في تحسين التشخيص .

Abstract

The thyroid hormones, thyroxin (T4) and triiodothyronine (T3), are tyrosine-based hormones produced by the thyroid gland primarily responsible for regulation of metabolism. An important component in the synthesis of thyroid hormones is iodine. The major form of thyroid hormone in the blood is thyroxin (T4), which has a longer half-life than T3. The ratio of T4 to T3 released into the blood is roughly (20 to 1). The level of thyroxin is affected by radiation. The aim of the study to determine and to assess the effects of continuous X-rays on thyroxin level in vitro quantitive measures. Thirty patients with hyperthyroidism disease were enrolled in this study. Blood samples were tested and irradiated by x-ray radiation source of total dose rate (0.4).Gry/sec. The level of thyroxin were determine before and after irradiation .The results showed that the level.of.thyroxine.are.significantly.reduced.(P<0.01).after.x-ray.irradiation. It is concluded that x-ray ionizing radiation, reduced thyroxin level by free radical forming and protein damaging.

Abstract

Asbestos is a naturally occurring silicate material and is often used as a building material for its excellent resistance to acid and heat. However, the material is known to cause adverse health effects and hence has progressively been banned. Following the revision of Japan's Ordinance on Prevention of Asbestos Hazards and Industrial Safety and Health Act enforcement ordinance in 2006, the proposed limit value for asbestos content was made more rigorous. As a result, in any product, the present content by weight of asbestos is stipulated to be below 0.1%.This article shows an example of rapid quantitative analysis of the chrysotile (a type of asbestos) using the new high-speed, wide-range detector OneSight.

Abstract

In the present work the effect of residual stress on the fatigue behavior of2024 Aluminum alloy was studied experimentally and numerically usingfinite element method with aid of ANSYS-11 software. All the testspecimens treated by annealing before any process to remove the internalstresses due to cold work. Residual stresses were imparted to the fatigue testsspecimens by heat treatment, pre-strain and welding. X-Ray diffraction wasused to measure the residual stress.The heat treatment; done on the test specimens with different temperature of(420, 450, 480, and 510) oC. After heat treatment; alloy mechanical propertieswere improved. For the heat treated specimens as the temperature increasedthe compressive residual stress increased to (27.06, 41.43, 72.8 and 85.6)MPa. That leads to increase the endurance fatigue limit by (32.93%, 40.48%,50.68% and 61.03%) respectively than other alloy as received. While in prestrain groups; the test specimens loaded to (265, 290, 315 and 340) MPa by atension test machine. As the applied load series were increased thecompressive residual stress increased to (16.51, 25.62, 51.54 and 62.44) MPawhich improve the endurance fatigue limit by (7.68%, 16.19%, 24.98%, and46.45%), respectively. An electrical arc and metal inert gas were used inwelding series to weld the test specimens, that present a tensile residual stressof (76.93 and 72.66) MPa, which reduces the endurance fatigue limit by(23.45% and 16.08%), respectively. The numerical results present fatiguebehavior, deflection and stress at any load, and show a reasonable agreementresults with an experimental one.

Abstract

Background: Mercury in dental clinic has been recognized as a potential health hazard. This evaluated the removal of Hg spills from different surface in dental clinic with tin in the metal backing for dental x-ray film.Materials and Methods: Hg 90 drops (each one of 0.2 g) placed on 9 different surfaces in the dental clinic, and were divided into: Group I (protective surfaces) subgroup 1 (mask) subgroup 2 (gloves) subgroup 3 (dental apron)Group II (dental instrument and equipment) subgroup 1 (metals, for example, the metal tray of sterilizer) subgroup 2 (dental chair unit) subgroup 3 (wet surfaces, for example, the vacuum suction tank of the sucker). Group III (other clinical surfaces) subgroup 1 (working bench) subgroup 2 (the floor) subgroup 3 (the carpet). The metal backing for x-ray film (0.4 g) placed on each Hg spill, and the time of adsorption was recorded in seconds using a digital timer.Results: The results showed adsorption of Hg spills to the metal backing for x-ray film in all groups except in the crevice of the carpet. Group I subgroup 2 showed the faster interaction (7.1 + 2.828 sec.) while group II subgroup 3 showed the slowest interaction (90.3 + 20.981 sec.).Conclusion: Hg spills on dental protective surfaces can be removed easily, while the most difficult spills to be removed were on the wet surface. Furthermore, Hg spills in crevis of the carpet can not be removed
