Study the Effect of Hydroxyl radical on the Monogermacyclobutane Molecule by using density functional theory

This work reports a theoretical study to investigate the electronic structure and optimized geometry for a saturated molecules group by using density functional theory (DFT) at B3LYP level with bases set 6-31G. Cyclobutane molecule is an original molecule before substitute one-carbon atom by one-germanium atom. The effect of substitute on cyclobutane molecule is discussed on the basis of the calculated electronic properties. The electronic properties included total energy, energy gap, ionization potential, electronic affinity, hardness and softness, which have been found with varying differences for each molecule, with comprehensive analysis of the calculated highest-occupied and lowest-unoccupied orbital (HOMO and LUMO respectively) energies. These properties also studied with substituting the one hydrogen atom by one hydroxyl (OH) radical in same molecular. The results in this study show that the calculated total energy, energy gap and ionization potential for cyclobutane have been found a good agreement with the previous studies. For other molecules, we have not found a reference data, so this study supplies a new data in this aspect. These calculations have been performed using Gaussian 03 package. Keywords: Cyclobutane, DFT, energy gap, ionization potential

Study Molding of Vortex state in the Atmosphere

الغلاف الجوي للأرض  يحتوي ككل على نظام معقد للغاية من الحركات يتغير بمرور الوقت. تتكرر الميزات  الرئيسية لهذه الحركات من عام إلى آخر ويتم عرضها جيدًا في المتوسط ​​والخرائط المناخية ، وهي نقطة البداية لاستنتاجات حول الدوران العام للغلاف الجوي. لذلك من المعروف أن حركة الغلاف الجوي لها طابع دوامي. هناك حالات أساسية لحركة دوامة ثلاثية الأبعاد ، حيث يؤدي تقارب الضغط المنخفض إلى حركة تصاعدية ، ويؤدي الاختلاف عالي الضغط إلى تدفق نزولي في حركة دوامة (إعصار). يمكن وصف حالات مجال  السرعة ثلاثي الأبعاد هذه باستخدام توسيع سرعة الحمل من حيث التدفق والوظائف المحتملة ، والتي تصف الهياكل الحلزونية لهذه الحركة. في هذا البحث ، تم تقديم معادلات تفاضلية جزئية بسيطة تلبي الحالة الأرضية لحركة الدوامة ثلاثية الأبعاد. يتضح أيضًا أنه عند → Re ، تتدهور حركة الدوامة إلى رياح جيوستوفيك، ويتم استبدال الحالة المقابلة لحركة الدوامة بالحالة الجيوستوفك.The Earth's atmosphere as a whole has a very complex system of movements that changes over time. The main features of these movements are repeated from year to year and are well displayed on average and climatic maps, which are the starting point for conclusions about the general circulation of the atmosphere. So it is known that the movement of the atmosphere has a vortex character. There are basic states of three-dimensional vortex motion, in which low pressure convergence leads to an upward motion, and high pressure divergence leads to a downward flow in a vortex motion (tornado). These states of the three -dimensional velocity field can be described using the expansion of the convection velocity in terms of stream and potential functions, which describe the spiral structures of this movement. In this paper, simple partial differential equations are introduced that satisfy the ground state of three-dimensional vortex motion. It is also shown that when Re → ∞, the vortex motion degenerates into geostrophic wind, and the corresponding state of vortex motion is replaced by the geostrophic state.                                                                                                                            &nbsp

TREATMENT MANNERS, GLYCEMIC CONTROL, AND C - REACTIVE PROTEIN IN PATIENTS RECEIVING ANTIDIABETIC OR ANTIDIABETIC WITH ANTIHYPERTENSIVE DRUGS IN BASRA

Objective: This study aimed at investigating the relationship between treatment manners, glycemic control, and C-reactive protein (CRP) serum level in patients receiving antidiabetic drugs (ADM) alone or ADM with antihypertensive (AHT) drugs in Basra.Methods: Patients receiving ADM or ADM with AHT drugs, not suffering from complications, were recruited from Al-Mawanee General Hospital in Basra. Socioeconomic characteristics, blood pressure (BP), and treatment plans were recorded. Blood samples were obtained to measure glycated haemoglobin (HbA1c), lipids profile, and high sensitive (hs-CRP).Results: A total of 26 men and 50 women were involved. Lower mean HbA1c was found in patients receiving ADM with AHT drugs compared with those on ADM drugs only (p=0.0013). Lower mean systolic BP (p<0.0001) and diastolic BP (p=0.0078) were found in patients receiving ADM drugs only compared with those receiving ADM with AHT drugs. Lower mean hs-CRP was found in women receiving ADM with AHT drugs compared with those on ADM drugs only. Treatment manners had no effect on mean hs-CRP in men and women receiving ADM with AHT drugs; however, there was a significant direct correlation of hs-CRP with HbA1c (p=0.002) and triglycerides (p=0.009), but inversely with high-density lipoprotein cholesterol (p=0.011) in women receiving ADM drugs only.Conclusion: High levels of hs-CRP are associated with poor glycemic control and dyslipidemia, therefore, consequently increased cardiovascular risk. Due to its value as a risk predictor, hs-CRP should be included in routine monitoring of Type-2 diabetic patients

Optimum matrix acidizing: How much does it impact the productivity

Formation damage is one of the big challenges for oil and gas oilfields development. Several types of formation damage most likely exist during the entire life of producing wells. Formation damage can occur during the drilling or coring operations, well completion, work-over and production. The most important problems that affect formation during drilling operations are mud filtrate and fines invasion. There are different damage mechanisms affect reservoirs for instance pore blocking by solids, clay swelling and dispersion and liquid block which all reduce effective permeability to hydrocarbons. The reduction in production and an excessive build up pressure in injection wells indicate the formation. Many techniques are developed to remove the formation damage and to improve the productivity of wells. Matrix acidizing is one of these method which depend on injecting acids into the formation below fracturing pressure to eliminate the damage around the well. In this study, comprehensive design procedures for the acid treatment have been introduced. The procedures include the determination of the damage type and the mineralogy of the formation. Accordingly, the selection of the appropriate acid for the treatment and the optimum volume of injected acid are explained in the study. Additionally, the research presents several models for the pre-flush volume and the main acid volume based on the radius of the damaged zone and the height of the formation. New technique has been proposed for determining the final permeability improvement ratio based on current and proposed productivity index. It has been found the pre-flush volume increase as the carbonate percentage in the formation increases while the main acid volume conversely proportional with the clay content in the formation

EVA  أن العامل الاكثر تأثيرا هو التعتيق الرطب بينما الاقل يحصل بواسطة التشعيع بالاشعة فوق البنفسجية. بينما تغير التركيب الكيمياوي الاكبر يحدث للعينة الخالية من اضافة Cyasorb , حيث ينتج من التعتيق الرطب أما التغير الاقل فينتج بواسطة التسخين الجاف.            This paper presents a sight about the chemical structure deformation of poly (ethylene-co-vinyl acetate) (EVA) samples according to the change ratio of rate constant values. Spectroscopy kinetics fluorescence curves are fitted for two characteristic wavelength domains of fluorescent intensities. The short wavelengths (320-400 nm) domain show spectra overlapping, while at long wavelengths (400-800 nm) domain spectra are arranged in regular for each specific accelerated aging time. The ratio of kinetics rate constant at long wavelengths to kinetics rate constant of short wavelengths is the criterion of the degree chemical structure deformation. Molar extrinsic coefficient relies on the chemical structure change. Through absorbance measurement, EVA samples have been classified into two groups. Presence of Cyasorb additive is the key point of the ranking. The effect of three different accelerated aging of dry (115 oC), damp (85% moisture, 85 oC), and irradiated (UV, 65 oC) aging have been considered for two samples of each group over different aging time. Spectroscopy of absorbance and fluorescent for aged samples have been discussed. In general, Cyasorb adding causes higher chemical structure deformation for the EVA sample. The most effective factor is the damp aging and the less one is the UV irradiation aging, while the biggest chemical structure change of Cyasorb-free sample is produced by damp aging and the less by dry heat.  &nbsp

Alpha-particle-induced complex chromosome exchanges transmitted through extra-thymic lymphopoiesis in vitro show evidence of emerging genomic instability

Human exposure to high-linear energy transfer α-particles includes environmental (e.g. radon gas and its decay progeny), medical (e.g. radiopharmaceuticals) and occupational (nuclear industry) sources. The associated health risks of α-particle exposure for lung cancer are well documented however the risk estimates for leukaemia remain uncertain. To further our understanding of α-particle effects in target cells for leukaemogenesis and also to seek general markers of individual exposure to α-particles, this study assessed the transmission of chromosomal damage initially-induced in human haemopoietic stem and progenitor cells after exposure to high-LET α-particles. Cells surviving exposure were differentiated into mature T-cells by extra-thymic T-cell differentiation in vitro. Multiplex fluorescence in situ hybridisation (M-FISH) analysis of naïve T-cell populations showed the occurrence of stable (clonal) complex chromosome aberrations consistent with those that are characteristically induced in spherical cells by the traversal of a single α-particle track. Additionally, complex chromosome exchanges were observed in the progeny of irradiated mature T-cell populations. In addition to this, newly arising de novo chromosome aberrations were detected in cells which possessed clonal markers of α-particle exposure and also in cells which did not show any evidence of previous exposure, suggesting ongoing genomic instability in these populations. Our findings support the usefulness and reliability of employing complex chromosome exchanges as indicators of past or ongoing exposure to high-LET radiation and demonstrate the potential applicability to evaluate health risks associated with α-particle exposure.This work was supported by the Department of Health, UK.
