En säker bakteriediagnostik kräver en korrekt provtagningsteknik, ett lämpligt transportsätt och rätt odlingsteknik. På grund av centralisering av verksamheter och ekonomiska begräsningar, är transport av prover till mikrobiologilaboratorium mycket vanligt. Detta medför behov av ett transportmedium som håller känsliga bakterier vid liv under långa transport- och förvaringstider. Dessutom skall transportrören klara av maskinell utodling som kräver ett vätskebaserat provtagningsmedium. Denna övergång minskar även arbetsbelastning och förbättra ergonomin hos personalen.

In the Swedish abattoirs there are assistants that judge the slaughtered animals in regard to diseases and injuries. All diseases and injuries assign different codes. This master?s thesis is about code 42 which means injuries of different kinds like for example bruises etc. These injuries have risen during the transport from the farm to the abattoir lairage or during the stay at the lairage before slaughter.

Since 2004, wind power has had the largest installation of new capacity compared to other energy sources in Sweden. Accommodating new wind power may require strengthening or rebuilding of the existing grid in areas where the grid is already loaded to maximum capacity. This master thesis examine the possibility of a new 400/130 kV substation in Yttermalung, Sweden, with a connection to the two neighboring regional grids in Dalarna and Värmland owned by Fortum. This substation would provide a new connection point to the Swedish transmission system as well as an interconnection of the two, currently separated, regional grids. Different expansion scenarios where a substation with and without series compensation or a phase shifting transformer (PST) to control active power flow were studied.

The electric vehicle market has potential to contribute to Sweden?s national goal to have a fossil fuel independent transport sector by 2030. However, the market answers to a lot of challenges making it difficult for the market to fully reach its potential. The volume of electric vehicles has seen a steady increase during the last year (2012), although many of these vehicles are mostly for PR purposes or bought by the public sector that wants to lead by example. Still, barriers in the form of high purchase costs, an anxiety for the limited battery capacity and the lack of standardisation are some of the problems that the market is struggling to solve.

Mathematical models possible to simulate are of great importance in order to make successful projects in the aircraft manufacturing industry. An aircraft fuel system is very complex, containing pipes, tanks, orifices, valves and pumps. The principal of this thesis is using the tool Easy5, which no longer is considered reliable enough in terms of development and support. This thesis tries to evaluate the Modelica language as a possible alternative to Easy5. To make this evaluation, the components concerned in the fuel library in Easy5 are implemented to the Modelica language.

I denna rapport undersöks hur mängden organiskt kol, TOC (Totalt organiskt kol), varierar i tid och rum i Mälarens avrinningsområde, samt vad det är som styr TOC-halten i Mälaren. Det är viktigt att förstå dynamiken hos TOC i Mälaren och i dess avrinningsområde eftersom ökat TOC i vattnet påverkar vattenkvaliteten och orsakar problem vid beredning av dricksvatten. TOC kan bland annat reagera med klor/UV-ljus och bilda cancerframkallande ämnen. Det kan också öka antal mikrober i vattnets distributionssystem.Arbetet omfattar analys av samband mellan elementen, transportberäkningar per ytenhet av elementen till Mälaren och en modelleringsansats för ett av avrinningsområdena. Rapporten innehåller även en jämförelse mellan de olika vattenföringsmodellerna samt uppmätt vattenföring för analys av eventuella systematiska skillnader mellan dessa som påverkar beräkningen av TOC och de andra elementens transport till Mälaren.Analysen av sambanden mellan variablerna TOC (mg/l), kaliumpermanganat förbrukning (KMnO4, mg/l), absorbans_F (F=filtrerad), järn (mg/l), mangan (mg/l) och SO4_IC (sulfat mätt med hjälp av jonkromatografi, mg/l), visade att vissa av dessa variabler är korrelerade med varandra.

This bachelor degree project was carried out at Saab AB Service and Repair, Arboga, Sweden. The objective was to design, construct and implement a new stable and reliable method of measuring the continuous vertical displacement (height) of the military search radar PS861 mounted on a hydraulic powered elevator. The end product needs to be durable enough to be fully operational in the harsh environment of an outdoor elevator shaft and yet as accurate and precise as possible since one of its purposes is to calibrate control equipment. Previously used technique has proven not to meet any of the above mentioned properties.A prototype using a high resolution quadrature output rotary encoder has been developed, allowing a completely digital interface. This new method has been evaluated in laboratory environment where tests have been conducted regarding both reliability and validity.

CTI- Central Tire Inflation är ett styr- och reglersystem som möjliggör att justera lufttrycket i däcken under färd på virkeslastbilar för att anpassa det till aktuell last och hastighet. Genom att köra med ett lägre däcktryck på virkesfordon är det möjligt att minska kostnaden för skogsbilvägar. SCA Skog vill skapa en CTI-strategi som ska innehålla handlingsplaner för hela kedjan från planering till transport. År 2009 minskade investeringsanslagen för vägar inom SCA Skog och Medelpads skogsförvaltning började bygga vägar som trafikeras av CTI-utrustade fordon. Syftet med arbetet är att utvärdera användningen av CTI åt SCA skog vid Medelpads skogsförvaltning. Datainsamlingen utgjordes av intervjuer med personer vid SCA som har arbetat med CTI någon gång sedan införandet. Totalt intervjuades elva personer. Ett arbetssätt för CTI identifierades.

Background: During the last decade climbing has become more popular and the numbers of climbers in Sweden have increased considerably. Most common are overuse injuries caused by the great stress and strain climbing creates on different parts of the body. Previous studies show that 75-90% of climbing injuries are localised in the upper extremity. Injuries affecting the lower extremity occur often acute and traumatic. Based on these facts and that the number of climbers constantly grows, it is more likely that the need of care from physiotherapist among climbers will increase.

The purpose of my task was to map the pallet flows at Findus and put together as well as analyze the problems. My work has also included finding out what alternatives there are to the present pallet exchange system and suggest measures to reduce the problems.The problems can be divided into poor quality and hygiene issues. The poor quality, for instance poor strength is due to arbitrary judgements and the fact that there are companies that make a system of manufacturing forged pallets of an inferior quality compared to the EUR-pallets. These pallets are marked with stamps more or less similar to the EUR-mark and taken into the exchange system. Of course there are rules how to judge a pallet but these rules are many and sometimes indistinct and there are a lot of marks to keep track of.The most dangerous part is when the pallets lack the prescribed carrying capacity.

The aim with this study is to through a research summary review experiences of growth and theparents caring ability among children who has grown up with parents having intellectual disabilites,and by empirical data illustrate how these persons today describe their childhood, their parentscaring ability and other cicumstances that have affected the growth. The results from the researchsummary are then to be compared with the results from the empirical data in purpose to reviewsimilarities and discrepancies.The study has a qualitative approach and it is based on foundings from earlier research andinterviews with four women whos mothers have intellectual disabilities.In the existing research of this issue there is a clear dichotomy between whether the researchershave focused on either the children or the parents. In both perspectives there are differentconceptions about whether a person with intellectual disabilities have the capacity to care for andraise a child, as there is about how the parents intellectual disaparment affects the child.The womens stories of the childhood are obviously unique, but they also have many experiencesin common, both among themselves as with what has been found in research. Children of parentswith intellectual disabilities have been classified as a risk group, wich has been shown by reversedroles for child and parent, lack of attachment to the parents and by insufficient care. Despite thedifficulties that the women have faced, they describe many parts of their lives in positive termstoday.There seems to be other influences in addition to the parents intellectual capacity that affect theesechildrens outcomes.

Avfall i stort har fått en annan innebörd i dag jämfört med tidigare decennier i och med att det nu går att återanvända, återvinna och utvinna energi ur det. Gips är ett avfall som förekommer som brandskydd i stor omfattning och förut gick majoriteten på deponi. Nya alternativ har dykt upp det är dock fortfarande mycket som går på deponi och det medför miljöproblem, främst i form av läckage av svavel.Syftet med studien var att genom telefonintervjuer se hur hanteringen av gipsavfall uppfattas av aktörer inom byggbranschen, hantering och transport av avfall och olika återvinningscentraler. Men även att se vilka miljörisker de olika aktörerna anser att gipsavfall kan leda till. De aktörer som intervjuades var inom området bygg; NCC, inom området hantering och transport av avfall; Sita och Ragn-Sells, inom området återvinningscentraler; en återvinningscentral från Uppsala och en från Malmö.Slutsatsen blev att aktörerna först och främst försöker återvinna gipset, går inte det är det deponering som är det sätt varpå gipsavfall hanteras.

At Forsmarks Kraftgrupp AB (FKA) forces on pipe systems due to transient flow are frequently calculated as a step to verify their structural integrity. In nuclear industries these forces are often calculated with a one dimensional thermal-hydraulic analysis-code called RELAP5. When calculations regarding more complex geometries are needed, the three dimensional code Fluent is often used. This code is highly time consuming and requires large computational power.This projects aim is to compare calculations of pressure, flow and forces carried out by RELAP5 and Fluent for an arbitrary pipe section during transient flow conditions. This has been accomplished by constructing a simple geometry for which a transient flow is simulated in both programs.

AbstractThis master thesis was performed at Scania transmission department in Södertälje, where the manufacturing of gears is done. Today a large amount of manual handling is performed between the machining and the hardening process. Most of the manual handling is done at the heat treatment department. The purpose of this master thesis is to give a suggestion on how to reduce or eliminate the manual handling at the heat treatment department. The possibility to use the same packaging throughout the processes will also be investigated.
