Evaluation of preanalytic methods in order to shorten the processing time before identification of fungal microorganisms by the MALDI-TOF MS

Identification of fungi is based on macroscopic observations of morphology and microscopic characteristics. These conventional methods are time-consuming and requires expert knowledge. For the past years Matrix-assisted laser desorption ionization-time of flight mass spectrometry has been used for routine bacterial identification in clinical laboratories but not yet in the same extension for fungi. In this study three preanalytic preparation methods for fungi were evaluated in order to shorten the processing time in routine laboratory performance.Clinically relevant strains (n=18) of molds and dermatophytes were cultivated on agar plates and prepared according to the different preparation methods for protein extraction. Each strain was analyzed in quadruplicate by the MALDI Biotyper and the database Filamentous Fungi Library 1.0.The results showed that the genus and species identification rates of the least time-consuming direct extraction method were 33% and 11% respectively.

Empowerment i multisystemisk terapi- en kvalitativ studie av MST teamet i Halmstad

The study was performed based on a qualitative method using a hermeneutical approach used to interpret the semi-structured interviews. The study aimed to investigate the Multisystemic therapy (MST) team in Halmstad municipality perceptions on the treatment method multisystemic therapy for youths from the ages of 12-18 years old.The questions were: Does the MST therapists experience that the MST is a method that leads to an improved situation for young people who receive the method? What do the MST therapists describe as opportunities and obstacles in the work with the method?The study builds on previous research on MST and empowerment based on MST. The study shows three therapists and an MST leader's experiences of the treatment and how it is aimed at influencing the parents and the youth for a change. From therapists statements it highlights how the MST method is designed for the young people?s motivation to change by means of the internal and external networks.

Carnegie: En studie av tillämpningen av "verkliga värden"

A recent development in the field of accounting has been an increasing use of fair values in financial reporting. In 2005, this development was reinforced in Sweden by the adoption of the International Financial Reporting Standards. The aim of this thesis is to discuss the problems related to the use of fair values, through a case study of the Swedish investment bank Carnegie. In May 2007, Carnegie announced that the result had been overly stated by 630 MSEK, due to the valuation of derivatives within the trading department. The empirical material consists of documents produced in the legal process between Carnegie and the Swedish Financial Supervisory Authority.

Balis trädgårdar

The urbanization of the world is increasing. How it affects bird populations have been well studied during the last decade, and comparisons between urban and non-urban habitats have been carried out. A common method for measuring habitat quality is to calculate the population density. This method is easy to use, but have been criticized during the last couple of years. In this study, data of population densities was compared with data on reproduction success.

CFD-simulering av kallras från fönster : Konvektorers och nischdjupets inverkan på lufthastigheter i rummet

During cold winter days it is likely that people in buildings with older windows or high glass facades experience thermal discomfort due to cold air down draughts. Earlier work has been aimed at finding analytical methods to predict the speed of the airflow in a room and in practice heating appliances are often placed beneath the windows to reduce the draught along the floor. In a study from 2012 Mohammad Parchami developed a method for estimating the required heating power to counteract the downdraught with such heating appliances. In this study, Computational Fluid Dynamics (CFD) was used to evaluate the usefulness of Parchami?s method and also to examine the potential of adapting the depth of the inward window sill as a means of decreasing the down draught.

EV/EBITDA : är det supermultipeln som kan generera överavkastning?

Bakgrund: Effektiva marknadshypotesen innebär att det inte går att utnyttja systematiska avvikelser på marknaden. Trots det finns det etablerade investeringsstrategier som investerare använder sig av för att generera överavkastning.Syfte: Syftet med studien är att undersöka huruvida det går att generar överavkastning genom att investera i företag som uppvisar en låg eller hög EV/EBITDA-multipel. Variablerna bransch och risk kommer även att undersökas med utgångspunkt från den eventuella förekomsten av en investeringsstrategi som genererar överavkastning.Genomförande: Teori inom området har byggt upp en grundförståelse för problemet, empiri har sedan hämtats från de olika företagen för att få fram EV/EBITDA-multiplar till de ingående portföljerna i studien. Aktiekurser har även inhämtats för att bygga grunden till empirin. Resultatet har sedan jämförts med OMXSPI samt med den riskjusterade avkastningen.Resultat: Av resultatet framkommer att det går att utnyttja en investeringsstrategi där investering görs i låga EV/EBITDA-multiplar.

Tidiga membranförändringar i hingstsperma som används för artificiell insemination :

The Annexin-V/propidium iodide (AV/PI) assay detects early membrane changes in spermatozoa and viability using flow cytometry. It is an objective method that evaluates a much larger number of single spermatozoa compared with the usual estimation of motility, the most commonly used method for routine sperm evaluation. In the present study four ejaculates from four stallions were used in a split-sample design to investigate whether and how the number of intact spermatozoa is affected over time and after incubation at different temperatures, either those recorded during shipment of stallion semen for AI (9 or 5°C) or room temperature (20°C). The Annexin-V results did not reflect the motility results that were monitored in parallel. While motility decreased over time, the number of spermatozoa with intact membranes (viable) remained unchanged for at least 21 hours following a short period of initial instability.

Analys och visualisering av optioner och andra finansiella instrument : Utveckling och studie av portföljhanteringssystem

Bakgrund: Ett sätt att minska risker vid handel med finansiella instrument är att bygga portföljer. För att kunna hantera portföljer med olika finansiella instrument och valutor samt kunna hantera flera portföljer samtidigt, används portföljhanteringssystem. Studenter kan genom att använda sig av sådana system lära sig hur finansiella marknader fungerar. Kraven på ett portföljhanteringssystem är inte desamma som kraven på ett kommersiellt system och därför finns det ett behov att utveckla en modell för denna kontext.Syfte: Denna uppsats ämnar bygga en modell i PowerPlus Pro som studenter kan använda sig av för att befästa sina kunskaper och öka sin förståelse för hur finansiella instrument fungerar.Metod: För att bygga modellen har kvalitativ metod används och för att studera hur portföljhanteringssystem ska byggas och anpassas efter studenters behov har kvalitativa intervjuer använts.Slutsatser: Vår modell uppfyller de krav som ställts på den och är anpassad för undervisning på ett universitet genom att den är användarvänlig och pedagogiskt uppbyggd. Modellen lämpar sig inte för användning av markadsaktörer.     .

Metod för att mäta förändring av city logistik : - En casestudie på Sandvikens kommun

To distribute goods to customers in urban areas is necessary to support the economic and social development in the cities, but has consequences that affect both residents of cities as well as the environment. The environmental effects of these types of transport involves not only the emissions of various pollutants, but also an increased noise level inside the cities. Many companies and organizations are working hard to change the distribution pattern to streamline transport in the urban area, while environmental impact is reduced. This is in line with what is called the City Logistics. The purpose of this thesis is to create a method for describing and measuring a given transport solution in order to compare it with an altered transport solution to achieve a more sustainable development.

Den sista vilan : vad kännetecknar en rofylld begravningsplats?

This essay examines the criteria for a peaceful cemetery. First there is a short history of the Swedish funeral place. After that follows the definitions of a peaceful place according to environmental psychology. From these definitions an analysis method is constructed for identifying a peaceful cemetery. The analysis method contains six criteria, shape of the entrances, existence of sound, vegetation character, the cemetery?s demarcation, the cemetery?s management and what feeling the cemetery mediates.The analysis method is put into practice on three cemeteries, Överklinten cemetery, Stockholm forest cemetery and the old cemetery in Malmö.

Metod för dosoptimering av digitalt detektorsystem i klinisk drift

The county of Dalarna is at present carrying through a process of digitalization where traditional x-ray film is being replaced with digital detectors. Earlier used methods for dose optimization turned out not being sufficient. This report presents a method to harmonize dose levels between x- ray sites equipped with Fujifilm imaging plate systems. An exposure index, S, related to the dose level of the examination is computed to every x-ray image. S turned out to be inversely proportional to the detector dose used at the examination.
