Luminescence and deep-level transient spectroscopy of grown dislocation-rich Si layers
I. I. Kurkina,I. V. Antonova,A. A. Shklyaev,S. A. Smagulova
AIP Advances , 2012, DOI: 10.1063/1.4748863
Abstract: The charge deep-level transient spectroscopy (Q-DLTS) is applied to the study of the dislocation-rich Si layers grown on a surface composed of dense arrays of Ge islands prepared on the oxidized Si surface. This provides revealing three deep-level bands located at EV + 0.31 eV, EC – 0.35 eV and EC – 0.43 eV using the stripe-shaped p-i-n diodes fabricated on the basis of these layers. The most interesting observation is the local state recharging process which proceeds with low activation energy (~50 meV) or without activation. The recharging may occur by carrier tunneling within deep-level bands owing to the high dislocation density ~ 1011 - 1012 cm-2. This result is in favor of the suggestion on the presence of carrier transport between the deep states, which was previously derived from the excitation dependence of photoluminescence (PL) intensity. Electroluminescence (EL) spectra measured from the stripe edge of the same diodes contain two peaks centered near 1.32 and 1.55 μm. Comparison with PL spectra indicates that the EL peaks are generated from arsenic-contaminated and pure areas of the layers, respectively.

Abstract: The research goal is to carry on the comparative analysis of medicines of various chemical structure, Telmisar-tan and Bisoprolol, and to reveal their effect on the arterial blood pressure level and the indices of various metabolic processes in patients with arterial hypertension. 60 out-patients with arterial hypertension (stage II risk III) both males and females aged 33-55 have been under study taking Telmisartan and Bisoprolol for 3 months. While treating the patients the arterial blood pressure level control and biochemical investigations for determination the indices of metabolic processes have been carried out. The investigated medications have provided the decrease of systolic and diastolic arterial pressure parameters, the increase of concentration of total and ionized calcium, chlorine ions, urea and total bilirubin in blood plasma. Therapy with Telmisartan has shown more significant increase of potassium level in erythro-cytes, decrease of levels of natrium, glucose, glycolized hemoglobin and triglycerides and increased contents of alani-naminotransferase and aspartataminotransferase. The course of therapy with Bisoprolol has restored the normal level of magnesium in blood plasma, has not have any influence on carbohydrate and lipid metabolism, increased the level of alaninaminotransferase and significantly increased the contents of total and ionized calcium, urea and creatinine. 3-months therapy with Telmisartan and Bisoprolol has proved the decrease of systolic and diastolic arterial pressure in patients with arterial hypertension. The medications under study have had active and variable effects on metabolic indices

Saratov Journal of Medical Scientific Research , 2010,
Abstract: At the background of the therapy for 3 months with Perindopril, Telmisartan and Bisoprolol, the patients with arterial hypertension were noted to decrease systolic and diastolic arterial pressure. The preparations under investigation had different effects on electrolyte metabolism. Therapy with Telmisartan turned out to have the least effect on electrolyte metabolism. Microalbuminuria is a risk factor in patients with arterial hypertension and may influence on the basic blood electrolyte balance. Bisoprolol should be recommended as the most preferable therapy for arterial hypertension from the pharmacoeconomic point of view. In order to control morning systolic arterial pressure the preference should be given to Perindopril, while for controlling evening systolic arterial pressure the preference should be given to Telmisartan

Saratov Journal of Medical Scientific Research , 2011,
Abstract: The aim of the investigation is to carry out comparative evaluation of metabolic and hemodynamic indices in patients with arterial hypertension (AH) and renal dysfunction; to study the interrelation between arterial blood pressure level normalization and the presence or lack of microalbuminuria (MAU) in the morning urine portion of patients with AH after therapy with antihypertensive preparations (APs) of various groups. Methods. 121 persons have been investigated, 91 out — patients of both sexes, aged 33-55, with the diagnosis of arterial hypertension of stage II risk III, who have been taking Perindopril, Telmisartan and Bisoprolol for3 months. The control of arterial pressure level, biochemical analysis of metabolic indices and morning urine portion test for microalbuminuria has been carried out. Results. MAU has been revealed in 17,6% patients, occurring more frequently in men than in women. Microalbuminuria is accompanied by reliable decrease of total and ionized calcium and magnesium concentrations, an increase of potassium level in blood plasma, increase of cholesterol, triglycerides, glucose and levels. Patients with AH and renal dysfunction reliably demonstrate higher levels of systolic and diastolic arterial pressure in the morning and evening hours, their normalization effect after APs intake is significantly interconnected with MAU presence. Conclusion. In patients with AH and MAU the main risk factors of cardio-vascular diseases development are more expressed. Microalbuminuria is a risk factor in patients with arterial hypertension and may influence on the basic blood electrolyte balance. While carrying out antihypertensive therapy the presence of MAU should be taken into consideration

Physics , 2012,
Abstract: Variable-coefficient Korteweg - de Vries equation is applied to describe the interfacial wave transformation in two-layer fluid of variable depth. The soliton dynamics in this fluid is studied. The solitary wave breaks in two transient points. One of them is the point when two-layer fluid transforms to the on-layer flow. The second one is the point where layer thickness are equaled. The soliton amplitude dependence on the thickness of lower layer is found.
