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.

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.

The juvenile offenders in our study have completed youth community service. A qualitative study was undertaken which include seven interviews. Our empirical data were compared and analyzed with previous research data.
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.
ADDICTION SEVERITY INDEX I PRAKTIKEN : - Om missbrukshandläggares erfarenheter av att använda ASI-intervjun
The purpose of this study was to understand how social workers experienced working with Addiction Severity Index (ASI) in relation to the goal set by the National Board of Health and Welfare. The method is spread nationwide and therefore it is of great importance to examine how the social workers themselves experience the demands and the resources surrounding ASI. We choose to do a qualitative study interviewing eight social workers at six different occasions. The result was analyzed using Max Weber?s ideal type bureaucracy and Michael Lipsky?s thesis on street-level bureaucrats.
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.
Kan strålar av ljus tyda det förflutna? : Användning av Reflectance Transformation Imaging (RTI) för att tyda runinskrifter på Pireus-lejonet
This paper deals with testing the method Reflectance Transformation Imaging (RTI) on the copy of the Piraeus-lion in Historic Museum in Stockholm. The purpose is to find out if it is possible to gather more information about the runic inscriptions. RTI is a method that records the surface normal of individual pixels in a digital photograph by analyzing the impact of light coming from different angles of entrance. RTI produces sort of a 3D-image of the object. There will be an overview of earlier interpretations of the runic scripts written on the lion as well as an overview of Varangians in the southeast.
Den svarta lådans pedagogik : En studie om läsinlärning på behavioristisk grund
AbstractThe phonics is traditionally firmly established within reading acquisition in Swedish schools. The curriculum, Lpo 94 gives spacious independence regarding the question of method and we have to be aware of our own point of view when we are making the decision regarding the method of reading acquisition. Is it tradition or is it our linguistic point of view that is the determining factor? Through this study of literature, different publications from different times are being studied and the ideas and the linguistic point of view are being discussed. Through comparing between the curriculums that have been replaced of one another, and attending to linguistic discussion and research, we will be able to see a change in the linguistic point of view.
