خلفية البحث: مرض السكري هو عامل خطر لأمراض القلب والأوعية الدموية وتصلب الشرايين وسبب مهم للوفاة. يرتبط خلل الدهون في الدم بشكل شائع بمرض السكري من النوع الثاني ويعتبر مؤشر تصلب الشرايين في البلازما علامة قوية للتنبؤ بخطر الإصابة بتصلب الشرايين وأمراض القلب التاجية. الهدف من البحث: دراسة ارتباط المؤشرات الدهنية لتصلب الشرايين لدى المرضى العراقيين المصابين بالسكري من النوع الثاني ولديهم أمراض قلبية وعائية. المرضى وطرق العمل: أجريت هذه الدراسة السريرية في مستشفى بغداد التعليمي/ مدينة الطب - بغداد في الفترة من تشرين الأول 2022 ولغاية شباط 2023. تم مشاركة 60 مريضًا مصاباً بالسكري من النوع الثاني في هذه الدراسة. ثلاثون مريضا منهم كانوا يعانون من أمراض القلب والأوعية الدموية و 30 غير مصابين بأمراض القلب والأوعية الدموية. تراوحت أعمارهم بين 40-55 سنة. تم اختيار 30 فردًا سليما كمجموعة سيطرة. النتائج: كان هناك ارتفاع كبير في فحوصات نسبة السكر والدهون في الدم لدى مرضى السكري المصابين بأمراض القلب والأوعية الدموية مقارنة مع أولئك الذين لا يعانون من أمراض القلب والأوعية الدموية ومجموعة السيطرة. أظهرت النتائج الحالية مستويات مرتفعة من نسب الدهون لدى مرضى السكري المصابين بأمراض القلب والأوعية الدموية. كشفت النتائج أيضًا عن مستويات عالية من البروتين الدهني غير عالي الكثافة لدى مرضى السكري المصابين بأمراض القلب والأوعية الدموية (241.8 ± 12.24 ملغم/ ديسيلتر) مقابل (150.1 ± 7.12 و 68.9 ± 5.1 ملغم/ ديسيلتر) لأولئك الذين لا يعانون من أمراض القلب والأوعية الدموية ومجموعة السيطرة على التوالي. كان مؤشر تصلب الشرايين للبلازما لدى مرضى السكري المصابين بأمراض القلب والأوعية الدموية مقارنة بمجاميع مرضى السكري والأصحاء (0.8 ± 0.09) مقابل (0.7 ± 0.03 و 0.2 ± 0.08) على التوالي. كان هناك ارتباط معنوي موجب بين مؤشر تصلب الشرايين للبلازما والعوامل الجسمية، صورة السكر والدهون في الدم مع نسبها لدى مرضى السكري مع وبدون أمراض القلب والأوعية الدموية. الاستنتاجات: تؤكد نتائج هذه الدراسة أن مؤشرات الدهون هي مؤشرات خطر لضبط نسبة السكر في الدم بقيمة تنبؤية أعلى من العوامل التقليدية. أيضًا، ممكن اعتبار البروتين الدهني غير عالي الكثافة ومؤشر تصلب الشرايين في البلازما من العوامل الهامة للسيطرة على نسبة السكر في الدم.
Silver selenide telluride Semiconducting (Ag2Se0.8Te0.2) thin films were by thermal evaporation at RT with thickness350 nm at annealing temperatures (300, 348, 398, and 448) °K for 1 hour on glass substrates .using X-ray diffraction, the structural characteristics were calculated as a function of annealing temperatures with no preferential orientation along any plane. Atomic force microscopy (AFM) and X-ray techniques are used to analyze the Ag2SeTe thin films' physical makeup and properties. AFM techniques were used to analyze the surface morphology of the Ag2SeTe films, and the results showed that the values for average diameter, surface roughness, and grain size mutation increased with annealing temperature (116.36-171.02) nm The transm

In particular and Iraq in general, as this led to a reduction in the areas of agricultural lands and in return an increase in arid lands and their desertifica- tion and the loss of their productive value, which as a result leads to the migration of the population, the change of land sex, the failure to achieve food security and dependence on the import of the food basket.
Phase change materials are known to be good in use in latent heat thermal energy storage (LHTES) systems, but one of their drawbacks is the slow melting and solidification processes. So that, in this work, enhancing heat transfer of phase change material is studied experimentally for in charging and discharging processes by the addition of high thermal conductive material such as copper in the form of brushes, which were added in both PCM and air sides. The additions of brushes have been carried out with different void fractions (97%, 94% and 90%) and the effect of four different air velocities was tested. The results indicate that the minimum brush void fraction gave the maximum heat transfer in PCM and reduced the time
... Show MoreIn this work; copper oxide films (CuO) were fabricated by PLD. The films were analyzed by UV-VIS absorption spectra and their thickness by using profilometer. Pulsed Nd:YAG laser was used for prepared CuO thin films under O2 gas environment with varying both pulse energy and annealing temperature. The optical properties of as-grown film such as optical transmittance spectrum, refractive index and energy gap has been measured experimentally and the effects of laser pulse energy and annealing temperature on it were studied. An inverse relationship between energy gap and both annealing temperature and pulse energy was observed.
In the current study, a direct method was used to create a new series of charge-transfer complexes of chemicals. In a good yield, new charge-transfer complexes were produced when different quinones reacted with acetonitrile as solvent in a 1:1 mole ratio with N-phenyl-3,4-selenadiazo benzophenone imine. By using analysis techniques like UV, IR, and 1H, 13C-NMR, every substance was recognized. The analysis's results matched the chemical structures proposed for the synthesized substances. Functional theory of density (DFT)
has been used to analyze the molecular structure of the produced Charge-Transfer Complexes, and the energy gap, HOMO surfaces, and LUMO surfaces have all been created throughout the geometry optimization process ut
the student of the structure of the city and its constituent elements will clearly sense the invisible relationships that underlie the different forms of urban activity, which in turn are defined by the generality of the urban patterns in that city, which will vary clearly according to the location in the city. These relations will be embodied in their true form in the interactions between the different uses of the earth, and the change that will result from their regularity in the form of entities in independent groups, which may share with each other a component of it.
Therefore, the process of controlling the functional interactions between the uses of the urban land and the awareness of t
Reverse Osmosis (RO) has already proved its worth as an efficient treatment method in chemical and environmental engineering applications. Various successful RO attempts for the rejection of organic and highly toxic pollutants from wastewater can be found in the literature over the last decade. Dimethylphenol is classified as a high-toxic organic compound found ubiquitously in wastewater. It poses a real threat to humans and the environment even at low concentration. In this paper, a model based framework was developed for the simulation and optimisation of RO process for the removal of dimethylphenol from wastewater. We incorporated our earlier developed and validated process model into the Species Conserving Genetic Algorithm (SCG

The feasibility of using hollow fiber ultrafiltration (UF) membrane and reverse osmosis (RO) membrane type polyamide thin-film composite in a pilot plant was investigated. Three different variables: pressure (0.5, 1, 1.5 and 2 bars), oil content (10, 20, 30 and 40 ppm), and temperature (15, 20, 30 and 40 ᵒC) were employed in the UF process while TDS was kept constant at 150 ppm. Four different variables: pressure (5, 6, 7 and 8 bar), oil content (2.5, 5, 7.5 and 10 ppm), total dissolved solids (TDS) (100, 200,300 and 400 ppm), and temperature (15, 20, 30 and 40 ᵒC) were mani
