Topics in Energy Release and Particle Acceleration in the Heliosphere
No full textThis thesis investigates both the release of energy in solar flares, and the acceleration and transport of particles in various astrophysical situations. While numerical simulations are central to this thesis, these are always motivated by analytical arguments.
A review of flare energy release is given in Chapter 2, with results presented in Chapters 3 and 4. The main goal of the flare work is to investigate the effect of viscosity on energy release rates. Scaling arguments and exact solutions of the magnetohydrodynamic equations are used to interpret the results of two-dimensional numerical simulations of magnetic reconnection. The results support viscous energy dissipation accounting for a significant fraction of flare energy release.
Chapter 5 contains an introduction to astrophysical particle acceleration, using the Fokker-Planck formulation. The theory introduced in this chapter is used to study electron transport in solar flare loops (Section 5.5). A key aspect of the analysis is the expression of the Fokker-Planck equation as a system of stochastic differential equations. A generalisation to the flare loop hard X-ray emission prediction of Conway et al. (1998) is obtained, giving a stronger dependence on density for dispersed initial distributions.
Chapter 6 uses the methods of the previous chapter to study the acceleration of cosmic-rays at the heliospheric termination shock. The applicability of the focused acceleration mechanism of Schlickeiser and Shalchi (2008) is examined using numerical simulations, which are interpreted using analytical arguments based on averaging the stochastic equations. The results show significant limitations in assuming a near-isotropic distribution, a requirement for the focused acceleration mechanism. In addition, momentum diffusion provides a significant effect that cannot be neglected. The theory is extended to include focused deceleration and pure momentum diffusion
Discrete element modelling of a soil-mesh interaction problem
No full textThe design strategies of metallic cortical meshes used for slope protection are mostly linked to the application of empirical and semi-empirical methods. This limitation is due to the difficulties in representing such complex large-deformation rock-soil-structure interaction problems: the intrinsic complexities of these structures is combined with the difficulties in describing the geometry both the mechanical and physical properties of the rock and soil behind. The Discrete Element Method proved their effectiveness in describing the non-linear and large strain behaviour of the soil, and recently also the mechanical response of steel wire meshes which are represented as regular patterns of remote interactions between nodes. In this work, a discrete element model of a double-twisted hexagonal wire mesh is calibrated on the base of experimental tensile tests on two wire types. The validation of the model is performed using the results of a standard punch test. The same mesh is then loaded by a granular layer constituted by discrete element particles mimicking the soil earth pressure. A comparison between the two load types is discussed with reference to the force-displacement curve and the distribution of the tensile stresses on the mesh panel. The effect of the boundary conditions is also analysed

The aim of this study was the clinical and anatomical features of innervation of the renal arteries.
The retrospective analysis of health statistics on the prevalence of resistant hypertension based on the Odessa Regional Mortem Bureau during 2011-2012 was conducted. The analysis of the results of the autopsy and subsequent histological examination of 30 bodies of deceased patients with resistant hypertension II and III stages has been done. The morphometry of renal arteries and their segments was conducted. Fragments of the renal artery were not larger than 1,0x1,0x1,0 cm, fixed in 10% neutral formalin and alcohol after standard wiring block embedded in paraffin. Sections 5.0-8.0 microns (in an amount of at least two sections with each block) were stained by the observation procedures recommended modern guidelines: hematoxylin and eosin, by Van Gieson; by Nissle, by Golgi and by Masson. The evaluation of the histological response rate in the vessels was performed visually and compared to the control group.
The greatest density of accumulation in the nerve ganglia determined adventitia proximal renal arteries, preferably on the frontal surface. Ganglions sizes ranging from 80 to 220 microns, larger than when the ganglia are located in the proximal renal artery. The main part of the sympathetic ganglia, located at a depth of 2-3 mm. Postbifurcation ganglia localization occurs in 32.2% of cases. The degree of fibrosis of the renal artery wall in hypertension does not preclude the implementation of radiofrequency catheter sympathectomy.
Key words: arterial hypertension, renal arteries, innervation, pathomorphology
The Impact of the Murder of Alexander Litvinenko on British Policy towards Russia
No full textThe bachelor thesis titled "The Impact of the Murder of Alexander Litvinenko on British Policy towards Russia" deals with the issue of British policy towards Russia in response to the murder of Alexander Litvinenko, which significantly cooled bilateral relations. The thesis focuses on the analysis of the security and diplomatic actions of the British government and their connection with economic strategies, which is interpreted through the theoretical framework of the thesis - the theory of Canadian political scientist Kalevi Holsti. Holsti's theory, which discusses the interaction of states' security and economic measures in the face of external threats, provides a guide to understanding the shape of the British response. To illuminate the context, an overview of the British policy towards Russia prior to the event is provided, as well as a detailed account of the life and tragic death of Alexander Litvinenko. The period of around one and a half year after the murder is examined to avoid the influence of other events on British policy. Based on the secondary literature studied and the primary sources available, the outcome of this thesis is an analysis of the British government's policy towards Russia in the wake of the incident and an assessment of the unevenness of the response across different..
Wave energy dissipation by anisotropic viscosity in magnetic x-points
No full textThe viscous dissipation of axial field disturbances in planar magnetic X-points is examined. It is emphasized that an accurate treatment requires a nonisotropic tensor viscosity whose components are governed by the local magnetic field. Numerical solutions are constructed, which compare the buildup of viscous forces using the tensor formulation against a simplified model based on conventional shear viscosity. The scaling of the global energy-loss rate with the viscosity coefficient is shown to follow for both the traditional shear viscosity and the Braginskii bulk viscosity. This suggests that viscous wave dissipation can occur quite rapidly, in a few tens of Alfvén times. The results imply that large-scale disturbances, generated by magnetic reconnection in the solar corona, should dissipate in a time on the order of a few minutes and significantly contribute to coronal heating
The Litvinenko case and its reflection in The Daily Telegraph
No full textThis bachelor thesis studies the manner in which the case of the former Russian spy Alexander Litviněnko's poisoning was handled in 2006 by the British newspaper The Daily Telegraph. Both quantitative and qualitative analyses have been used for that purpose. The theoretical part of the thesis explains the factors influencing the process of encoding of the meanings into mediated contents, and the process of their subsequent decoding by the public. The analytical part presents a detailed description of how the concrete news texts on the Litvinenko case published by The Daily Telegraph could have been perceived by their recipient. Hypotheses have been set for the analysis; the confirmation or denial of their validity outlines The Daily Telegraph's methods of news reporting production and the terms in which the news texts are conceived in this newspaper
Particle acceleration scalings based on exact analytic models for magnetic reconnection
No full textObservations suggest that particle acceleration in solar flares occurs in the magnetic reconnection region above the flare loops. Theoretical models for particle acceleration by the reconnection electric field, however, employ heuristic configurations for electric and magnetic fields in model current sheets, which are not solutions to the MHD reconnection problem. In the present study, particle acceleration is discussed within the context of a self-consistent MHD reconnection solution. This has the advantage of allowing poorly constrained local parameters in the current sheet region to be expressed in terms of the boundary conditions and electric resistivity of the global solution. The resulting acceleration model leads to energy gains that are consistent with those for high-energy particles in solar flares. The overall self-consistency of the approach is discussed

Abstract
Iron deficiency anemia (IDA) is a common complication of pregnancy which have negative health effects for both mothers and their babies. Adequate therapy for IDA is an effective treatment for anemia in pregnancy. The aim of this study was to assess the efficacy of IDA treatment in pregnant women with Tardiferon. 45 pregnant women with IDA stage 1 were followed-up in 2019. All women were prescribed with prolong-release ferrous sulfate (Tardyferon). Treatment duration was 30 days (80 mg/1 tablet daily). Blood count was evaluated after 1 month. In pregnant women who received Tardyferon, the levels of hemoglobin, erythrocytes, and hematocrit as well as serum iron, ferritin, and transferrin saturation have significantly increased. 7 women (15.6%) have reported on adverse effects (i.e., constipation and obstructed defecation). Treatment was generally well tolerated thus providing good adherence to therapy. Therefore, in pregnant women with IDA Tardyferon improves blood count a nd results in clinical improvement.
Keywords: ferrous sulfate, iron deficiency anemia, pregnancy, Tardyferon.
