Vliv foam rolleru na svalové napětí po zátěži / Effect of foam roller application on muscle tone after physical loadPatschová, Miroslava January 2019 (has links)
Title: The effect of foam roller on muscle tone after physical load Objectives: The aim of this thesis was to summarize theoretical knowledge about muscle, changes in muscle tension and possibilities of its affect. The aim of the practical part was to find out the effect of the foam roller on muscle tone after exercise. Methods: Practical part of this thesis was processed in biomechanical laboratory at FTVS UK in Prague and included 16 probands. We measured muscle tone of biceps brachii, m. triceps surae and m. quadriceps femoris before exercise, then the probands performed an activity aimed at increasing the muscular tension of the musculature mentioned above, after which we measured the muscle tension again. The foam rolling of each muscle group lasted for 60 seconds and then we measured the muscle tone for the last time. A myotonometer device was used and the data were transmitted by KISTLER MULTICHANNEL CHARGE AMPLIFIER and processed by the DeweSoftX3 (64 bit) programme in SIRIUS DEWEsoft S-BOX2 computer. At the end, we compared measured values with subjective sensations of the probands who filled quick questionnaire. Results: The measurement showed that after exercise, the muscular tensions of the muscle groups we selected increased, and at the same time that the application of the foam roller...

Roten till det onda : en studie i häxmotiv, kvinnlig sexualitet, husmoderlighet och moderlighet i Ulla Isakssons historiska roman Dit du icke vill / The Root of Evil : a study of witches, female sexuality, housewife-attitudes and disposition for maternity in Ulla Isaksson´s historical novel Dit du icke villWidén, Anita January 2008 (has links)
<p>Ulla Isaksson (1916 – 2000) wrote many novels, often with a woman or several women as protagonists. In <em>Dit du icke vill</em> (“Where Thou Willst Not”) from 1956 she depicts a crisis of faith in a woman, which would not have been successful had she chosen a contemporary setting. She uses an adequate historical framework, the prosecution of witches in Sweden in the 17<sup>th</sup> century, well documented in reliable sources.

Synthese von Übergangsmetallkomplexen der 4. Nebengruppe zur Herstellung verschiedenartiger PolymereMeichel, Eduard 29 October 2002 (has links) (PDF)
Zusammenfassung:
Die vorliegende Arbeit lässt sich thematisch in drei Bereiche gliedern. Der erste Teil
handelt von der Synthese stark elektronenziehender Ligandensysteme und deren Umsetzung
zu Metallocendichloriden. Es zeigt sich, dass die Umsetzung von pentafluorbenzolhaltigem
Cyclopentadien, Inden oder Fluoren mit Silizium-Verbindungen nicht zu der gewünschten
Reaktion zu Si-verbrücken Systemen führen, sondern, dass sich andersartige Si-F-Moleküle
bilden. Zugängliche, unverbrückte Komplexe zeigen im besonderen eine geringe Stabilität
im Vergleich zu nicht-C6F5-haltigen Metallocenen.
Die Hauptthematik der Arbeit beschäftigt sich mit der Synthese von in 2-Position
funktionalisierter sowie verbrückter Indene und deren Umsetzung zu Metallocenkomplexen.
Hierbei interessiert vor allem der sterische Einfluss der am Ligandensystem sitzenden
Gruppen. Die Darstellung der Inden-2-verbrückten Indene erstreckt sich über eine
Bromaddition, thermodynamische Freisetzung von HBr, Grignard-Reaktion und anschließender
Brückenbildung mit Cyclopentadien- und tert.Butylamineinheiten. Weiterer Bestandteil
dieses Abschnitts ist die Umsetzung der synthetisierten Moleküle zu Metallocenverbindungen.
Dabei werden auf diesem Wege Sandwich- bzw. Halbsandwich-Komplexe in guter Ausbeute erhalten.
Der dritte Bereich beschäftigt sich mit der Umsetzung von Titan-4-chlorid gegenüber
unterschiedlichern Trimethylsilyl-substituierten Indenen. Durch Substitution eines
Chloratoms durch eine Phenolatgruppe erhält man die Indenyldichlortitanphenolate.

Globally convergent evolution strategies with application to Earth imaging problem in geophysics / Des stratégies évolutionnaires globalement convergentes avec une application en imagerie sismique pour la géophysiqueDiouane, Youssef 17 October 2014 (has links)
Au cours des dernières années, s’est développé un intérêt tout particulier pour l’optimisation sans dérivée. Ce domaine de recherche se divise en deux catégories: une déterministe et l’autre stochastique. Bien qu’il s’agisse du même domaine, peu de liens ont déjà été établis entre ces deux branches. Cette thèse a pour objectif de combler cette lacune, en montrant comment les techniques issues de l’optimisation déterministe peuvent améliorer la performance des stratégies évolutionnaires, qui font partie des meilleures méthodes en optimisation stochastique. Sous certaines hypothèses, les modifications réalisées assurent une forme de convergence globale, c’est-à-dire une convergence vers un point stationnaire de premier ordre indépendamment du point de départ choisi. On propose ensuite d’adapter notre algorithme afin qu’il puisse traiter des problèmes avec des contraintes générales. On montrera également comment améliorer les performances numériques des stratégies évolutionnaires en incorporant un pas de recherche au début de chaque itération, dans laquelle on construira alors un modèle quadratique utilisant les points où la fonction coût a déjà été évaluée. Grâce aux récents progrès techniques dans le domaine du calcul parallèle, et à la nature parallélisable des stratégies évolutionnaires, on propose d’appliquer notre algorithme pour résoudre un problème inverse d’imagerie sismique. Les résultats obtenus ont permis d’améliorer la résolution de ce problème. / In recent years, there has been significant and growing interest in Derivative-Free Optimization (DFO). This field can be divided into two categories: deterministic and stochastic. Despite addressing the same problem domain, only few interactions between the two DFO categories were established in the existing literature. In this thesis, we attempt to bridge this gap by showing how ideas from deterministic DFO can improve the efficiency and the rigorousness of one of the most successful class of stochastic algorithms, known as Evolution Strategies (ES’s). We propose to equip a class of ES’s with known techniques from deterministic DFO. The modified ES’s achieve rigorously a form of global convergence under reasonable assumptions. By global convergence, we mean convergence to first-order stationary points independently of the starting point. The modified ES’s are extended to handle general constrained optimization problems. Furthermore, we show how to significantly improve the numerical performance of ES’s by incorporating a search step at the beginning of each iteration. In this step, we build a quadratic model using the points where the objective function has been previously evaluated. Motivated by the recent growth of high performance computing resources and the parallel nature of ES’s, an application of our modified ES’s to Earth imaging Geophysics problem is proposed. The obtained results provide a great improvement for the problem resolution.

Previous issue date: 2016-02-02 / Fundação de Amparo a Pesquisa do Estado de São Paulo / Cosmic rays are strongly influenced by solar, geomagnetic and atmospheric
phenomena. CARPET detector, conceived for cosmic rays observation with energies
in the range between 105 - 1012 eV, is an important tool for the study of these
phenomena. The Earth s atmosphere conditions are also affected by changes in the
cosmic rays flux, therefore, cosmic rays characterization is important to define physical
and chemical conditions of our atmosphere. To characterize the cosmic rays flux
variations, detected on the ground, prior elimination of atmospheric pressure and
temperature effects on ground level is needed, thus, data recorded by meteorological
instruments on CASLEO were used for that corrections. To eliminate the effect of
temperature through the whole vertical atmosphere it was applied the integral and
the mass-average temperature method by using vertical temperature profiles. Both
methods were tested using CARPET-TEL data for the year 2009, this data were
previously corrected by pressure influences. The mass-average temperature method
shows a better response when comparing the corrected CARPET date with neutron
monitor observations .The whole cosmic rays flux data analysis, for CARPET-TEL
data corrected by integral method (for the period 2006/04/01 - 2014/06/30), shows
an anti-correlation with sunspot number and a clear seasonal variation after 2008.
Two Forbush decreases (FD), were detected by CARPET which were produced
by geo-effective CMEs. Both FD onsets coincided with the interplanetary shock
instant, which preceded intense geomagnetic storms. With these results, we can reinforce
that CARPET is an important tool to study long and short term cosmic
rays behavior, because it has a similar response to experiments that operates at
atmosphere particle energy ranges. / Os raios cósmicos são fortemente influenciados pelos fenômenos solares, geomagnéticos e atmosféricos. O detector CARPET, concebido para a observação dos raios cósmicos com energias na faixa compreendida entre 105 e 1012 eV, é uma ferramenta importante para o estudo desses fenômenos. As condições da nossa atmosfera são também afetadas pelas variações no fluxo de raios cósmicos que chegam a Terra, portanto sua caracterização é importante para se definir as condições físicas
e químicas da mesma. Para caracterizar as variações do fluxo de raios cósmicos a partir de observações no solo é necessário a eliminação prévia da influência dos efeitos da pressão e temperatura atmosférica na superfície, para tal foram utilizados
dados meteorológicos obtidos no CASLEO. Para a eliminação do efeito da temperatura ao longo de toda atmosfera foram utilizados o método integral e o método de temperatura ponderada pela massa que utilizam perfis verticais de temperatura. Os dois métodos foram testados para o ano de 2009 com os dados do canal TEL do CARPET previamente corrigidos pela pressão, sendo que o método de temperatura
ponderada pela massa apresentou uma resposta melhor ao se comparar os dados corrigidos com os dados observados com monitores de nêutrons. A análise de todos os dados do fluxo raios cósmicos do canal TEL do CARPET (1/04/2006 a 30/06/2014) corrigidos pelo método integral, mostra a anti-correlação com o número de manchas solares, e uma variação sazonal pronunciada após 2008. Foram detectados dois decréscimos Forbush (FD) produzidos por CMEs geo-efetivos. O início de ambos FD coincidiu com o instante do choque interplanetário, que antecedeu
tempestades geomagnéticas intensas. Com estes resultados reforçamos que o CARPET é uma ferramenta importante para estudo das modulações de raios cósmicos de longo e curto prazo porque apresenta uma resposta semelhante com os experimentos que fazem observações em outras faixas de energia.

Strategic Human Resource Management : en kvalitativ studie om organisationens förmåga att behålla nyckelmedarbetare / Strategic Human Resource Management : a qualitative study on the organizations capability to retain key employeesElm, Dana, Grindeland, Rebecca January 2017 (has links)
Under de senaste decennierna har HRs roll förändrats inom organisationerna. Från att vara enlägre administrativ funktion har HR ökat i betydelse och anses idag vara en strategisk resurs,vilket har lett till att begreppet SHRM myntats. Inom SHRM återfinns rekrytering, hanteringav humankapitalet och bevarande aktiviteter. Fokus bör ligga på bevarandet av nyckelmedarbetaresom är viktiga för organisationens konkurrenskraft på arbetsmarknaden när det idag tillstor del är arbetstagarens marknad. Syftet med vår studie är att undersöka hur organisationeranvänder HR-funktionen för att locka nyckelmedarbetare att stanna kvar, med fokus på framgångsfaktorer för ett lyckat strategiskt HR-arbete, samt dess påverkan på det psykologiska kontraktet. Vi har använt oss utav kvalitativa intervjuer med tre informanter som ingår i en organisations ledningsgrupp. Materialet har sammanställts och analyserats genom en tolkande ansats där vi med stöd av tidigare forskning identifierat relevanta begrepp som undersökts empiriskt. De slutsatser som vi kan dra om SHRM som arbetssätt är att det krävs kunskap och insikt hos ledningen om vad för potential HR-funktionen har att bidra med till organisationen för att kunna implementera SHRM som arbetssätt. Angående bevarande åtgärder för att behålla nyckelmedarbetare bör organisationer först och främst tillkännage att nyckelmedarbetare finns för att de ska kunna motiveras till att vilja arbeta med bevarande aktiviteter för att behålla dessa. Vi kan även dra slutsatsen att det psykologiska kontraktet bortprioriteras när personalomsättning har blivit en naturlig del av organisationens vardag. / Great changes have occurred in HR over the last few decades. From being a lower, administrativefunction, HR has developed to a strategic resource in, operating in the higher levels of the organization, which has lead to the development of SHRM. Within the field of SHRM we can find recruitment, management of human capital and activities to decrease turnover. Attention should be paid to retain key employees whom are of great importance for creating a competitive advantage for the organization on the labor market. The purpose of this study is to investigate how organizations use the HR-function to increase retention among key employees; focusing on success factors for a strategic HR-work and its effect on the psychological contract. We've used qualitative interviews containing three informants that represent an organizations operational management team. The material has been assembled and analyzed through an interpreting approach where we, supported by theories and previous research, have identified relevant terms that have been investigated empirically. A conclusion regarding SHRM, as a practice, is that it demands a high level of knowledge and insight within the operational management team regarding the diversity of HR and how it can contribute to the organization in order to be implemented within the organization. Regarding activities to decrease turnover to keep key employees, organizations primarily need to signify the existence of key employees to even consider wanting to work with these kinds of activities. Furthermore, we have identified the lack of priority that the psychological contract gets if turnover has become a natural part of the everyday life within the organization.
