Bensodiazepiners beroendepotential – möjlig faktor till minskning i användningen / Dependency potential of Benzodiazepines - a possible factor to the decrease in usage

Faras, Fatima January 2016 (has links)
Introduktion: Bensodiazepiner har ända sedan de introducerats till marknaden varit mycket populära och är bland de mest förskrivna läkemedlen. Trots populariteten samt den höga användningen är bensodiazepiner en problematisk läkemedelsgrupp med anledning till deras höga beroendepotential. Bensodiazepiner ska enligt behandlingsrekommendationer endast förskrivas som sista alternativ och användas under en begränsad period för att undvika beroendeutveckling, vilket oftast inte blir fallet i primärvården. Syfte: Syftet var att undersöka hur användningen av bensodiazepiner har sett ut mellan 2006 och 2014 och om beroendepotentialen var en möjlig faktor till hypotesen att användningen minskat– för att uppmärksamma problem med användningen av dessa läkemedel. Material och metoder: Artiklar hämtades från databaser som PubMed samt Google Scholar. Statistiken över användningen hämtades från Socialstyrelsens statistikdatabaser och presenterades i form av tabeller och grafer. Resultat: Denna studie undersökte om just beroendepotentialen var en möjlig faktor till hypotesen att användningen minskat – och hypotesen stämmer. Statistiken visade att användningen av många bensodiazepiner har minskat markant under den perioden som undersöktes; som mest troligt beror på de nya riktlinjerna och behandlingsrekommendationerna som tagits fram mellan 2009-2010. Trots att användningen av bensodiazepiner minskat stadigt har istället en ny trend upptäckts; att bensodiazepinbesläktade substanser, som zopiklon, ökar markant. Detta innebär att behoven av farmakologisk behandling fortfarande är densamma då användningen av bensodiazepiner och bensodiazepinbesläktade läkemedel inte har varierat signifikant under den undersökta perioden. Konklusion: Nya selektiva bensodiazepiner med obefintlig risk för beroendeutveckling och smalare biverkningsprofil är under utveckling; dessa kommer med störst sannolikhet lösa många av beroendeutvecklings-problemen som för närvarande uppstår vid användning av bensodiazepiner och besläktade substanser i primärvården. / Introduction: Ever since benzodiazepines were introduced to the market they have been very popular and are among the most prescribed drugs. Despite the popularity and the high usage of benzodiazepines, this group of drugs is problematic due to their high dependence potential. Benzodiazepines should according to treatment guidelines only be prescribed as a last option and be used for a limited period of time to avoid the development of dependency - which is often not the case in primary care. Aim: The aim was to examine the usage of benzodiazepines between 2006 and 2014 and if the dependency potential was a possible factor to the hypothesis that the use has decreased – in order to draw attention to the problems associated with benzodiazepines. Methods: The articles were retrieved from the databases PubMed and Google Scholar. Statistics on the usage were taken from the Board's statistical databases. Results: This study investigated if the dependency potential was a possible factor to the hypothesis that the usage of benzodiazepines have decreased – and the hypothesis is correct. Statistics showed that the usage of many benzodiazepines have declined significantly during the period examined; most likely due to the new guidelines and treatment recommendations developed between 2009-2010. Although the usage of benzodiazepines declined steadily; a new trend was discovered, namely the prominent increased usage of benzodiazepine-like drugs such as zopiclone. This means that the needs of pharmacological treatment is unchanged since the usage of benzodiazepines and benzodiazepine-like drugs have not varied significantly during the examined period. Conclusion: New selective benzodiazepines with non-existent risks of development of dependency as well as a narrower side effect profile is under development. These will most likely resolve many of the dependency issues currently arising from the usage of benzodiazepines and related substances in primary care.

Studies of the Higgs boson using the H → ZZ → 4l decay channel with the ATLAS detector at the LHC

Garay, Francisca Montserrat January 2016 (has links)
Following the announcement of the discovery of a new particle on the 4th of July 2012 at the ATLAS and CMS experiments at the LHC, many efforts were needed for the understanding of its properties and to discern whether it is the Standard Model Higgs boson. The research presented in this thesis is based on the H → ZZ(*) → 4l decay channel. Three main contributions are discussed: the Standard Model Higgs boson mass measurement, the search for a heavy Higgs boson, and lastly, the implementation of a kinematic likelihood fitter as a new approach to improve the invariant mass resolution of the final states. The Standard Model Higgs boson mass measurement is presented. The measured mass is 124:51± 0:52(stat)± 0:06(syst) GeV for the combined data taken during 2011 and 2012 (4:6 fb-¹ at 7 TeV and 20:7 fb-¹ at 8 TeV). Contributing to the mass measurement, a tool was developed to validate the model used by generating several pseudo datasets from Monte Carlo samples and fitting them with the profile likelihood. The results show that the model is correct and only small deviations are seen in the parameters of interest, mH, and the signal strength, μ. Studies in the asymptotic limit show that these deviations are a symptom of low statistics in some of the final states. The search for a heavy Higgs boson is presented as well. No significant excess of events over the Standard Model prediction is found. A simultaneous fit to the profile likelihood gives 95% confidence level upper limits on the production cross-section of a heavy Higgs times the branching ratio to Z boson pairs in the mass range from 140 GeV to 1 TeV. Contributing to this search, a pseudo dataset, called Asimov dataset, is created from the Monte Carlo samples to test the profile likelihood fits and validate the model used. The results show that fit the model is correct. In addition, the limits are also interpreted in the context of Type I and Type II Two Higgs Doublet Models (2HDM). Finally, a Kinematic Likelihood Fitter (KLFitter) is studied and used to constrain the Z boson mass as an alternative to the standard tool used for the 2011 and 2012 measurement. This affects the distribution of the invariant mass, m4l, from which the Higgs boson mass is inferred. Small improvements are seen in the invariant mass resolution when higher hypothetical Higgs boson masses are considered.

Deslocamentos em Z² : equação cohomológica e operadores de transferência

Artuso, Everton January 2016 (has links)
Nosso objetivo nesse trabalho é estudar o comportamento dos operadores de transferência em f0, 1gN2 , um associado ao deslocamento horizontal (se1 ) e outro associado ao deslocamento vertical (se2 ). Construímos uma equação cohomológica para fins de ampliar a gama de funções às quais os operadores de transferência se aplicam. Estudamos também o comportamento do operador de transferência obtido pela composição dos dois operadores citados e, em condições de comutatividade, encontramos um autovalor e uma autofunção associada, ambos estritamente positivos, e uma automedida para o operador dual, associada ao mesmo autovalor. Tal automedida é um estado de equilíbrio. Além disso, estudamos algumas propriedades ergódicas de transformações de blocos. / In this work we study the behavior of the transfer operators in f0, 1gN2 , one associated with horizontal shift (se1 ) and other associated with vertical shift (se2 ). We build a cohomological equation for the purpose of expanding the range of functions to which the transfer operators apply. We also study the behavior of the transfer operator obtained by the composition of the two cited operators and, in the conditions of commutativity, we find an eigenvalue and an associated eigenfunction, both strictly positive, and an eigen measuse for the dual operator, associated with the same eigenvalue. This eigen measure is an equilibrium state. Furthermore, we study some ergodic properties of block transformations.

Search for R-parity violating supersymmetry in multilepton final states using the ATLAS detector

Klein, Matthew Henry January 2017 (has links)
This thesis presents a search for R-parity violating supersymmetry at sqrt(s)=13 TeV, using approximately 13.3 fb-1 of data collected by ATLAS in 2015 and the first half of 2016. Events are required to contain at least four leptons (electrons or muons only) that are not the product of a Z boson decay, and this requirement results in a low Standard Model background and a high sensitivity to various physics models beyond the Standard Model. No significant deviations from the Standard Model are observed in data, and results are used to set upper limits on the event yields from processes beyond the Standard Model. In a simplified model of chargino production with indirect R-parity violating decays, limits are extended by approximately 400 GeV relative to the Run 1 search, excluding chargino masses below 1.1 TeV.

Låt oss lära av de [o]döda - En motivstudie av Max Brooks´ World War Z: An Oral History of the Zombie War

Karlsson, Rasmus January 2019 (has links)
The purpose of this paper is to examine, through the process of close reading, the usage of different motives and narrative perspectives in Max Brooks´ bestselling novel World war Z: An Oral History of the Zombie War, such as narration, the usage of the zombie and moral projections. As this paper also takes an overviewing pedagogic direction, the paper aims to present the positive outcome of reading fiction, in alignment with the envisionment-arguments of Judith A. Langer, and how this can be implemented in the Swedish school system. A great amount of different claims were made in the analysis, due to the setting of the narratological hermeneutic alignment. For instance, the analysis revealed that WWZ could be read as an exposition of human behavior, when pushed to the edge of extinction, but it can also be seen as a mockumentary in book form – exposing some of the backsides of the capitalistic system. As for the pedagogic perspective, Langer’s concept of envisionment shows that merging the reading of fiction with group discussion can widen pupils grasping of different world phenomena, and thus stimulate their will for a lifelong learning, which correlates with one the of the core objectives and values in the Swedish school curriculum.

Scotland's regional print economy in the nineteenth century

Williams, Helen Sarah January 2018 (has links)
Printing has been one of Scotland's most significant industries since it was introduced over 500 years ago but remained for much of the period, a local industry. The Scottish publishing and printing industries in the nineteenth century left many documentary traces, but most research has concentrated on large urban centres such as Edinburgh, Glasgow and Aberdeen, with regional centres of print production all but ignored. In the nineteenth century, these local print economies served the business, administrative, political and leisure needs of an increasingly urbanised Scotland. My research is focused on the operation of the support structures and networks which developed among operative printers in Scotland's regional print centres from around 1830 to the end of the nineteenth century. As a case study I have selected the Royal Burgh of Dumfries, the most important market town in south-west Scotland, which was also a stop on the route between central Scotland and the industrial centres of Lancashire, and further south to London. A local printing industry developed during the eighteenth century, and by 1830 Dumfries was the home of a range of businesses in the printing and allied trades. The examination of the local print economy investigates the businesses and organisations engaged in print production and distribution in the local area, the technologies which were in use, and the material record of the town. The individual 'print trade lives' are considered in some detail, looking at the range and variety of career patterns in the industry. The options for a larger study of print networks based on trade records are also considered. Sources for the study include local and regional trade society records, business records, trade journals and other publications, and contemporary (mainly local) newspapers. It also draws on technological manuals and other secondary material in Edinburgh Napier University's Edward Clark Collection.
