Zvonaři, kostelní zvony a jejich osudy na území historického Loketska a českého Chebska / Manufacturers of bells, church bells and their destinies in the territory of the historic Loket and Cheb regions

Bělohlávek, Miloš January 2021 (has links)
The diploma thesis deals with church bells as specific instruments of liturgy and lived faith on the example of today's Karlovy Vary Region, respectively historical regions Loketsko and Chebsko. Part of the text will focus on individual families who were engaged in casting bells. Emphasis is placed on the social and economic status of these families, their social mobility and the level of production in different epochs. These topics are traced from the early Middle Ages to the period of requisitions of bell funds during the world wars. At the same time, the work will attempt the first comprehensive mapping of historical bell collections in today's Karlovy Vary Region and give an explanation of the use of bells in church practice, taking into account the regional specifics of the culture of Egerland. Thanks to the connection to Germany and the important position of Cheb and Loket, there have been many bell-making manufacturers since the Middle Ages. In the early modern period, together with the development of mining activities in the Slavkov Forest and in the Ore Mountains, the prestige of the bell-making craft increased. Therefore, most of the church bells preserved to this day come from this period. Thanks to the parish archives, chronicles and topographies from the turn of the 19th and 20th...

Objektivizace využití kineziotapingu k ovlivnění svalového napětí při epikondylitidě / The objectification of using of kinesio taping to influence a muscle tone in epicondylitis

Rosenmüllerová, Lenka January 2014 (has links)
Title The objectification of using of kinesio taping to influence a muscle tone in epicondylitis. Objectives The aim of this master thesis is to find an effect of inhibitive kinesiotape application to muscle tone of hypertonic m. extensor digitorum communis and to pain of lateral epicondyl in lateral epicondylitis. Method The master thesis is divided to theoretical part and empirical research, which is based on the first part. The evaluation of m. extensor digitorum communis tension after kinesiotape application is provided by myotonometry method. The measurement is performed in 5 tested persons before and after two-day kinesio tape application. The questionaire Numeric pain rating scale helps to find a change of pain before and after kinesio tape application and then the dependence of pain to muscle tone change. Results The myotonometer measurement found a decrease of m. extensor digitorum communis tension for 4 from 5 tested persons after two-day application. The pain of lateral epicondyl was reduced for all probands. Keywords lateral epicondylitis, tennis elbow, muscle tone, kinesio taping, myotonometer

MUSCLES ACTIVATIONS DURING "SHOULDER MOUNT" POLE ACROBATIC EXERCISE

Sanni, Modinat January 2016 (has links)
Author: Bc. Modinat Sanni Supervisor: Ing. Miroslav Vilímek, PhD Title: MUSCLES ACTIVATION DURING "SHOULDER MOUNT"POLE ACROBATIC EXERCISE Purpose: This study is an empirical - theoretical study presents the literature review regarding to the topic of the shoulder function anatomy, kinesiology, biomechanics, non-traumatic injuries of the shoulder and their prevention by using the available literatures. Further, the study also compares by surface electromyography the amplitudes, shapes and durations of myoelectric signals of m. latissimus dorsi, m. pectoralis maior, m. biceps brachii, m. infraspinatus and m. supraspinatus of dominant shoulder in two healthy individuals during acrobatic exercise on vertical pole known as "Shoulder Mount". The purpose was monitor the changes in two different conditions; i.e. kinesiotape and elbow brace and compare with the control condition for the reason of finding out their ability to affect the myoelectric activities of selected muscles. Further, the Shoulder Mount exercise had recorded by six Qualisys cameras for motion analyses. Methods and materials: The potentially eligible scientific articles perform a search of studies on the topic of kinesiotapes and tennis elbow brace as measured by EMG mainly on myoelectric activity of the shoulder complex were seared from...

Studies of Nuclear Fuel Performance Using On-site Gamma-ray Spectroscopy and In-pile Measurements

Matsson, Ingvar January 2006 (has links)
<p>Presently there is a clear trend of increasing demands on in-pile performance of nuclear fuel. Higher target burnups, part length rods and various fuel additives are some examples of this trend. Together with an increasing demand from the public for even safer nuclear power utilisation, this implies an increased focus on various experimental, preferably non-destructive, methods to characterise the fuel.</p><p>This thesis focuses on the development and experimental evaluation of such methods. In its first part, the thesis presents a method based on gamma-ray spectroscopy with germanium detectors that have been used at various power reactors in Europe. The aim with these measurements is to provide information about the thermal power distribution within fuel assemblies in order to validate core physics production codes. The early closure of the Barsebäck 1 BWR offered a unique opportunity to perform such validations before complete depletion of burnable absorbers in Gd-rods had taken place. To facilitate the measurements, a completely submersible measuring system, LOKET, was developed allowing for convenient in-pool measurements to be performed.</p><p>In its second part, the thesis describes methods that utilise in-pile measurements. These methods have been used in the Halden test-reactor for determination of fission gas release, pellet-cladding interaction studies and fuel development studies.</p><p>Apart from the power measurements, the LOKET device has been used for fission gas release (FGR) measurements on single fuel rods. The significant reduction in fission gas release in the modern fuel designs, in comparison with older designs, has been demonstrated in a series of experiments. A FGR database covering a wide range of burnup, power histories and fuel designs has been compiled and used for fuel performance analysis. The fission gas release has been measured on fuel rods with average burnups well above 60 MWd/kgU. The comparison between core physics calculations (PHOENIX-4/POLCA-7) and the in-pool measurements of thermal power indicates that the nodal power can generally be predicted with an accuracy within 4% and the bundle power with an accuracy better than 2%, expressed as rms errors.</p><p>In-pile experiments have successfully simulated the conditions that occur in a fuel rod following a primary debris failure, being secondary fuel degradation. It was concluded that massive hydrogen pick-up takes place during the first few days following the primary failure and that a pre-oxidized layer does not function as a barrier towards hydriding in an environment with a very high partial pressure of hydrogen. Another series of in-pile experiments clearly indicate that increased UO<sub>2</sub> grain size is an effective way of suppressing fission gas release in LWR fuel up to the burnup level covered (55 MWd/kgUO<sub>2</sub>).</p>
