Erytrocyten, den röda blodkroppen, innehåller proteinet hemoglobin (Hb) vars främsta uppgift är att transportera syre till kroppens alla vävnader. Tillgången till tappat blod från blodgivare är mycket viktig inom sjukvården. Det är viktigt att blodpåsen tappas, hanteras och lagras på rätt sätt för att undvika onödig hemolys av erytrocyter. För att se till att hemolysgraden håller sig under det rekommenderade gränsvärdet på <0,8 % utförs regelbundna kvalitetskontroller på erytrocytkoncentrat (e-konc) vid förvaringstidens utgång som är 42 dagar. Syftet med studien var att undersöka hur hemolysgraden (%) i erytrocytkoncentrat stiger under förvaringstiden, samt att se om upprepad mekanisk hantering vid tillverkning av dessa påverkar hemolysgraden.

GE Healthcare wants to investigate whether additive manufacturing would be an alternative method in their workshops in the Umea? plant. Additive manufacturing is called 3D printing in everyday language and manufactures details by building them up layer by layer in an automated machine. The purpose of this work is therefore to investigate how mature additive manufacturing methods are and how they could be used at GE.The work has been divided into three parts. The first section investigates how additive manufacturing would work in the production workshop at GE.

This paper aims to broaden the discussion on how press freedom can be a powerful tool in the war on corruption. Previous studies have shown a significant relationship between more press freedom and less corruption, it also shows that the causal link runs from press freedom to corruption and not the other way around. There are quite a few studies on the impact of a free press on corruption and therefore there is a lot more to be published on this issue.This paper looks at press freedom as one of the most important parts of a democratic society and that it plays a vital role in reducing corruption as both an informant on key issues and also as a ?watchdog? on society. But press freedom cannot be seen as an ?easy fix? in a country or the international community's struggle to reduce corruption.

Rapporten är en sammanställning av gruppens samlade erfarenheter och lärdomar av ett projekt vars syfte var att utveckla ett verktyg som ska visualisera svarstider mellan mobila klienter och datacenter. Genom att använda kontinuerlig prototypning har gruppen kunnat arbeta på ett användarna sätt för att uppfylla kundens verkliga behov. För att uppnå detta användes utvecklingsmetodiken Kanban. Under projektets gång anpassades metodiken för att bättra passa in i arbetet.Projektets användartester har lett till sammanfattande erfarenheter om visualisering av data. Visualiseringar som projektgruppen ansetts tydliga uppfattades inte alltid på samma sätt av användarna.

The continuous process of urbanization results in demands on research and development for ecological and sustainable city development. Because of this, the current systems for wastewater treatment may have to be improved. In order to evaluate new technologies for municipal wastewater treatment, a development project has been initiated for the new district Hammarby Sjöstad in Stockholm. The project is lead by the company Stockholm Water. High environmental standards have been put up for the district, as it must be twice as good as an ordinary new district.

Under våren år 2013 har Emilia Andersson, en designingenjörsstudent på Högskolan i Skövde, utfört ett produktutvecklingsprojekt i samarbete med HAGS Aneby AB. Syftet med projektet var att utveckla en vippgunga vars storlek skulle vara anpassad för barn i åldrarna 1-3 år. Målet var att vippgungan ska kunna säljas över hela världen samt uppfylla den amerikanska standarden och europastandarden för lekredskap.Projektet inleddes med en förstudie och teori-fas, där bland annat litteraturstudie och konkurrentanalys genomfördes och annan information samlades in för att få djupare kunskaper inom ämnet. Därefter började idéer och koncept genereras, som sedan genomgick utvärderingar, så som användartester, vilket ledde till ett slutkoncept. Konceptet utvärderades med hjälp av bland annat hållfasthetsberäkningar och en antropometrisk analys.Den slutgiltiga vippgungan kan trots anpassningen för åldersgruppen, inte bara användas av 1-3-åringar utan också av äldre barn, tack vare att konstruktion och framförallt handtag ger extra lekvärden.

The purpose of this master thesis is to construct a steering transmission, for a trackedvehicle, containing two hydraulic circuits which are connected. The steeringtransmission should be mechanical to avoid steer-by-wire.BAE Systems Hägglunds has in an earlier study examined a system with two hydraulicpumps and one hydraulic motor, but the safety of the system wasn?t sufficient.To achieve sufficient redundancy there must be two hydraulic motors, which arecontrolled separately. When the two systems are connected in one point, this point is acritical part of the system because it directly affects both circuits. If one of the hydrauliccircuits fails the other should be able to operate independently as a steeringtransmission.

This is the end report of my final exam at Medieteknik. It covers the planning, work process and review of a Flash based web application that I set out to do. The goal was to create a user friendly, interactive e-shop with embedded functionality for playing music, displaying rich media content and researching possible payment solutions, to enable buying music files online. The project involved creating the user interface, the programmatic functionality of a Flash client (an SWF file). Also, setting up an Apache HTTP Server and establishing a working ?bridge? between the Flash client and the web server with Flash Remoting components and AMFPHP.

This thesis was conducted at AB Fredr Wagner in Ösmo in Nynäshamn, Sweden.AB Fredr Wagner provides solutions for the graphic industry and has been asked by acustomer to develop a product that can simplify handling of EUR-pallets, namely amechanical arrangement, further called pallet exchanger that can switch from anempty pallet to a fully loaded one using only hand force.The goal with the thesis was to create design documents for a pallet exchanger, andalso from those documents to manufacture a prototype for testing and evaluation.A field trip was made to the customer, IKAB mailing in Huddinge, where the palletexchanger is thought to be placed. The purpose of this field trip was to get an insightinto the current work condition and need of change, as well as to gather informationregarding the requirements when it comes to size and robustness of the palletexchanger. Existing equipment on the market that can perform similar tasks werestudied in order to find an optimal solution for the actual pallet exchanger.After the field trip and gathering of information the concept generating phase began.The method used for generating concepts was brainstorming. To decide on whichconcept to use, a concept selection matrix was created. The selection criteriaincluded in the matrix came from the requirements for the pallet exchanger.

AbstractAttitudes towards the reference situation and the meetings between library users and librarians have become the subject of much debate in the library setting today. The aim of this two years master´s thesis has been to examine six librarian?s attitudes and apprehensions concerning the interactions between the librarian and the users in the library setting. We were also interested in knowing how a library can work to become more service oriented and customer centred. We conducted six interviews with librarians located at three different libraries in Sweden.

The content of the following report is the summarized result of three students thesis at Blekinge Institute of Technology in co-operation with Water Jet Sweden AB. This report will give the reader a description of principles how to measure the abrasive mass flow in a waterjet cutting system. The work began with a visit to Water Jet Sweden AB to get a closer look at the problem. When the analysis of the problem was done the criteria were defined in the form of demands and desires. The main task of the criteria was to guide the search for the solution. The work proceeded with an extensive search for abrasive flow meters along with obtaining information about flow measurement in general. When the search for abrasive flow meters resulted in nothing all the efforts were concentrated on finding a principle of measurement that could cope with the criteria.

This study examined the factors influencing dairy farmers´ decisions to invest in automated milking systems (AMS). The problem studied involves uncertainty, information and complexity for dairy farmers in specific decision contexts. The frame of reference in the thesis combines contingency theory and decision theory and is used in a qualitative analysis of a set interview with dairy farmers who have recently bought an AMS and salespersons from Delaval, one of the AMS suppliers.The aim of this study is to develop an understanding of the decision making processes of dairy farmers, and in particular to identify which types of factors influence the outcome of an investment decision in the technological development of a farm.The study uses Thompsons` (1967) theory about the structure that organizations develop to handle the input of information. Thus, interest is focused on how a farm business structure handles information in the AMS decision, investigating the differences in information with Delaval?s "feed first principle" system and Lely?s "free cow traffic" system.The results of the qualitative interviews with the dairy farmers who bought an AMS show that there are three important factors that influence the outcome: employees, suppliers and the owner.

Föreliggande arbete utgör en delstudie i projektet Automatiserad telefonuppföljning inom Kriminalvården. Projektets övergripande syfte var att undersöka tillämpbarheten av Interactive Voice Response (IVR) som en modern metod för utvärdering, övervakning och påverkan av intagna som blivit villkorligt frigivna från ett fängelsestraff. IVR är en metodik baserat på automatiserade telefonintervjuer som bl. a innebär att en dator har programmerats för att ringa upp, ställa frågor, registrera svar och ge feedback till klienterna. I tidigare publikation från projektet undersöktes med hjälp av automatiserade telefonuppföljningar (IVR) hur stress och mående samt användande av alkohol och droger utvecklas under de trettio första dagarna efter avslutad anstaltsvistelse (Andersson et al, 2011).

Introduktion: HIV-infektion medför en kronisk och progressiv sjukdom som, i obehandlad form, leder till en successiv försämring av immunförsvaret och utvecklandet av AIDS.Syfte: Att vid två lärosäten undersöka sjuksköterskestudenters kunskaper om HIV och inställningen till behovet av HIV-testning.Metod: En empirisk tvärsnittsstudie med deskriptiv och komparativ design med kvantitativ ansats. Genomförd som enkätstudie bland studenter vid Högskolan i Gävle och Uppsala Universitet (N=95), som studerade på sjuksköterskeprogrammets tredje år. Resultat: Majoriteten (88,4 %) angav korrekt att samlag med fler än en partner ökar risken att smittas med HIV. Tre studenter (3,2 %) angav felaktigt att det finns ett vaccin mot HIV-infektion. Nästan hälften (42,1 %) saknade kunskap om att glidmedel, tillsammans med kondom, inte minskar risken för HIV-smitta.
