Hluk na farmách pro odchov brojlerů a jeho šíření do okolního prostředí. / Noises on farms for breeding broilers and its spreading to surrounding neighbourhood

TŮMA, Marek January 2013 (has links)
The aim of this thesis on the topic "Noises on farms for breeding broilers and its spreading to surrounding neighbourhood" was to find out how the noise load influences the surroundings of two farms for breeding broilers. Repeated measures and following analysis of the particular values of the noise load, was used to determine, whether the relevant legislation and other norms are respected. Calculations of equivalent level of acustic pressure were used to compare chosen cases and to final evaluation.

Pohyb tekutiny s tlakově závislými materiálovými koeficienty při povrchovém zatížení / The motion of a fluid with pressure dependent material moduli under a surface load

Janečka, Adam January 2012 (has links)
In the present work, we study the motion of homogeneous, isotropic, incompressible fluid with viscosity depending on the pressure. The motion is studied in a infinite domain under a surface load by a prescribed pressure on one of the boundaries. This so called free boundary is due to the exerted pressure deformed and is also subject of study. After an acceptable simplification and prescribing suitable boundary conditions, the problem is solved at first analytically using the perturbation method, then numerically by means of the spectral methods. The effort is to observe any differences in the motion in comparison to commonly used Newtonian fluid.

Motion of a body in a fluid with pressure dependent viscosity / Motion of a body in a fluid with pressure dependent viscosity

Sláčík, Stanislav January 2013 (has links)
A lot of technologically relevant incompressible fluids exhibit a substantial variaton of viscosity with the pressure;a falling cylinder viscometer is frequently used for the measurements, determining the viscosity indirectly from the time it takes the sinker to fall a given distance. The relation between the sinker fall velocity and the fluid viscosity is, however, derived under the constant viscosity assumption. The objective of the present thesis is to perform a numerical simulation of the viscometric experiment, assuming an explicit form of the pressure-viscosity dependence and realistic parameter values and to quantitatively assess the difference in body motion to the Navier- Stokes model. The computational method proposed, handling both the nonlinear constitutive relation and the body motion, was tested on simple problems with analytical solutions. The semianalytical relation for the Navier-Stokes model, also re-derived here, is compared to the computational results.The validity of the assumptions used in the theoretical derivation, based on the results of the numerical simulation, is discussed regarding the geometry of the viscometer.

Analysis of care in patiens at risk for arterial hypertension in pharmacy I. Author: Stanislav Gregor1 Tutor: Josef Malý1 Consultant: Stanislav Havlíček2 1 Department of Social and Clinical Pharmacy, Charles University in Prague, Faculty of Pharmacy in Hradec Králové 2 Czech Chamber of Pharmacists, Prague Introduction: Arterial hypertension represents a serious health problem. Despite of the fact that great attention is paid to an early diagnosis and therapy of arterial hypertension, it remains compensated insufficiently in a number of patients. Objectives: The aim of the thesis was to analyse the possibilities of pharmaceutical care provided to patients who are at risk of arterial hypertension. Methodology: Blood pressure was measured from the beginning of October till December 2012 in a public pharmacy in Moravská Třebová. The blood pressure was measured by a pharmacist by means of a validated and calibrated tonometer. Other data were collected from a directed interview with the pharmacy client. The data were evaluated in Microsoft Excel 2007 and processed by means of the frequency analysis. A retrospective analysis of drug problems was further performed in patients who have been using pharmacotherapy or food supplements. Results: The data were obtained from 196 pharmacy clients (31 % of men and...
