Evaluation of an automated multiplex real-time RT-PCR assay for rapid detection of Influenza A and B viruses

Influenza is a viral infection that affects global health and economy with its endemic and sometimes pandemic spread. Rapid detection of Influenza viruses enables antiviral use and can bring financial savings. It is also essential for the global surveillance of prevalent Influenza strains. RT-PCR is considered the most specific and sensitive method for detection of Influenza, but Influenza mutates at a high rate and it is therefore crucial that RT-PCR methods are updated regularly.In 2014, Cepheid released their Xpert Flu/RSV XC assay, which can detect Influenza A and B and RSV by multiplex RT-PCR in approximately one hour. The aim of this study was to evaluate this assay at Laboratoriemedicin Västernorrland by using the laboratory?s previous PCR assay for detection of Influenza viruses as reference method.Real-time RT-PCR was used to compare Xpert Flu/RSV XC to the reference method.

En riktig man är modig : En preventionskampanj om den idealiserade mansbilden

Men commit more suicide than women all over the world. They commit more violent crimes and are more inclined to alcohol abuse. There are studies that relate this behaviour to the hegemonic image of masculinity.My work focuses on Switzerland. The suicide rate in Switzerland is worrying, for men between 15 and 44 years suicide is the most common cause of death. There is no national suicide prevention and no information or prevention that highlights the connection bet- ween the hegemonic image of masculinity and the suicide rates.

Uppfödning av okastrerade hangrisar - ett alternativ till obedövad kirurgisk kastrering av smågris

Pigs kept for meatproduction are often surgically castrated to prevent aggression and boartainted meat. Castration without analgesia and anesthesia is painful and causes a lot of stress to the pig. There are alternatives such as to surgically castrate the male pigs with analgesia and/or with anesthesia, immunocastrate or keep them as intact males. In Sweden the most common practice is to surgically castrate the pigs before they are seven days old. The impact on the pig is that the incision causes pain and stress, which may lead to changes in behaviour, reduced appetite, reduced growth and a higher risk of infections.

Betydelsen av individualiserad information till hjärtsviktspatienter

Inledning: Risken för återinskrivning minskar om patienten har kunskap och kan hantera hjärtsvikten utifrån egenvårdsråd. Förmågan att ta till sig information har även en central roll i detta. Hjärtsviktspatienter med dålig följsamhet i sin egenvård av sjukdomen skrivs oftare in än de som har bra följsamhet. Minskad förståelse och kunskap kring sjukdom leder till minskad möjlighet för patienten att förstå information, läsa och följa medicinska rekommendationer samt skriftliga och muntliga instruktioner.Metod: Ett frågeformulär delades ut till patienter på två hjärtsviktsmottagningar i Mellansverige. Skillnader mellan skriftlig information testades mot skriftlig och muntlig information och analyserades med Mann-Whitney U test.

Att ställa frågan om våld i nära relation vid inskrivningssamtalet på en psykiatrisk avdelning : - ett kvalitetssäkringsarbete

Background: Intimate relationship violence is physical, psychological or sexual violence that a person is exposed to in a relationship. There is a strong correlation between intimate relationship violence and mental health problems. A psychiatric ward at a hospital in Sweden, is working with a new routine. According to this routine every new patient should be asked about intmate relationship violence as a part of the admission interview.Objective: The objective of this study was to study how the healthcare personnel is working with the routine, and also to study response rate, interventions and how the work has developed over time.Method: A quantitative study with a retrospective and descriptive studydesign. One hundred and two medical records were reviewed.

Implementing a receiver in a fast data transfer system : A feasibility study

This report is an outcome of a master degree project at Linköpings University in co-operation with Micronic Laser Systems AB. The purpose with this master degree project was to investigate how to implement a receiver in a data transfer system. The system consists of several data channels, where every channel consists of three parts: driver, transmission lines and receiver. The driver send low amplitude differential signals via the transmission lines to the receiver that amplifies and converts it to a single-ended signal. The receiver has to be fast and be able to feed an output signal with high voltage swing.

Vitamin- och mineraltillskott för barn : Utbud, innehåll samt kunskap och attityder kring dessa produkter hos personal vid apotek och hälsokosthandel

Background:Chronic heart failure (CHF) is a complex clinical condition. The higher survival rate after heart attack and other heart diseases, plus aging population, has led to more CHF patients. Symptoms can have negative impact on exercise capacity, ability to perform activities of daily living and quality of life. Heart failure clinics have been established to help better quality of life. Helping to stabilize and maintain patients´ health can reduce the need of hospital admission.

Har en gemensam valuta resulterat i en minskad prisspridning? : En jämförande studie på priskonvergens inom euroländer i förhållande till övriga EU länder

In 1993 the internal market within the European Union was formed and ensured free movement of goods, services, capital and people. This led to the removal of trade barriers between members of the European Union. When opening up for competition, price differences between countries decreased and more jobs were created. A single currency was introduced by eleven countries in 1999 with the goal of reducing transaction costs, eliminating exchange rate risk and to further simplify trade. In 2001 Greece joined the collaboration and introduced the euro.

Energieffektivitet i datahallar

The number of data centers and their capacity is increasing throughout the world. Theenergy used in these data centers and the emissions from the use are increasing at thesame rate. The total use of energy will double from 2008 to 2011 based on the trends indata centers use. Research in this area says that the emissions from data centers willhave surpassed the level of airline traffic in 2020. The index used today to compare howefficient a data center is, called PUE, is lacking some information.

V?ldet vuxenv?rlden inte n?r - En studie om socialsekreterares syn p? och arbete med v?ld i ungas parrelationer

This study examines how social workers in child and youth units within Social Services perceive and experience working with violence in young people's intimate relationships. The study aims to highlight whether there is a need for a domestic violence team within the child and youth units. Violence in young people?s close relationships is a growing societal issue, with limited establishment within the research field. While research on the frequency of such violence has increased, studies focusing on tailored support measures have lagged behind.

Influence of the habitat on the potential for cannibalism and population dynamics in stream-dwelling European grayling (Thymallus thymallus L.)

Cannibalism can have major influence on fish population dynamics. A prerequisite for cannibalism is that the cannibal and the potential victim meet, and besides density effects, the encounter rate between cannibals and their victims is therefore also largely dependent on habitat use and habitat heterogeneity. In this study I quantified and compared the potential for cannibalism in stream-dwelling European grayling populations in three rivers in Jämtland by means of habitat classifications. I also analyzed population dynamic consequences of varying the potential for cannibalism in terms of intensity, using a physiological structured population model. Findings based on habitat characteristics were that the potential for cannibalism is in general not favourable in these types of streams.

Hur en okontrollerad expansion av IT-projekts omfattning undviks

Today there is an even higher demand on IT-projects success rate compared to a few years ago. IT-projects must be handled more efficiently and result in a more profitable investment. In order to make the handling of IT-projects more efficient and create profitability the developers must have a broad understanding of the IT-projects characteristics and which factors that affect the result of the projects. Changes within IT-projects are often carried out through the development of a system. Since this change is more common when it comes to IT-projects it is important to handle risk and change within these kinds of projects in order to prevent and avoid uncontrolled changes.

Prissättningen av bostadsrätter: Vilka faktorer påverkar priserna, vad är riktpriset för en lägenhet?: - En mikrostudie av Södermalm i Stockholm

Those who have invested in apartments, i.e. tenant-ownership, within the city centre of Stockholm have gained a higher than expected return on investment due to a buoyant real estate market. During the latest twelve-month period, the prices have risen more than 20 per cent in the city of Stockholm, resulting in an increased wealth together with a higher debt burden among investors. The aim of this thesis is to investigate which factors determine the prices from a micro perspective, and to what extent. An attempt is particularly made to estimate the degree of capitalization of the monthly fees; a factor which has turned out to be important according to other studies; but also to construct pricing models in order to set target prices for apartments.

Samband mellan tjockleken hos PVD-skikt och förslitningsbeteendet vid svarvning

This project has as main goal to study the influence of the coating thickness, deposited by arc-PVD- technology, on the wear resistance of coated cemented carbide inserts in three different turning operations. An additional effort has also been made to develop a new test method for evaluating flank wear resistance. Three different coating types (Coating A, Coating B and Coating C) have been studied in three distinctive thicknesses (2, 4 and 6 µm) for each type. For two of the coating types (Coating A and B) special studies has been done with the thickest coating, creating two additional coating versions of the thickest coating, by changing various deposition parameters, with the aim to enhance the cohesive properties of the coating and lower the residual stresses at the cutting edge. The results show increased crater wear resistance with increased coating thickness for all coating types, but the amount of increase changes with coating type (Coating A>B>C).

Marknadsanalys av ett svenskt transportsystem med höghastighetsgodståg.

In Sweden plans to build high speed railways have been around since the early 1990s and the planshave developed to be more precised since. The future Swedish high-speed rail network is supposedto consist of two lines. Götalandsbanan; from Stockholm to Gothenburg, and Europabanan fromJönköping through the Öresund Region to Hamburg.The description of the aim to build high-speed railways in Sweden has in former reports always beento achieve rapid passenger traffic between big Scandinavian cities and Europe. There are almostnothing mentioned about the possibilities of high-speed transports of cargo on these railways. Thisstudy aims to clarify the freight transport market for Götalandsbanan and Europabanan.Today there is only one transport system with high-speed freight trains.
