Flowcytometric technology has been widely used for measurement of the absolute numbers of T-lymphocytes subsets in Human Immunodeficiency virus (HIV), defining the disease state, monitoring antiviral treatment, and identifying any risk for opportunistic infections. A manual preparing of the samples is required. More recently an automated and enclosed blood cell counting, Celldyn Sapphire has been introduced. In this study the performance of the Flow cytometer EPICS XL as a reference method for analysis of CD3+, CD4+ and CD8 T-lymphocytes was evaluated with blood from 40 individual?s samples.

Background: When a person suddenly pass away, the relatives often arrive to the Emergency Department under chaotic circumstances. In this critical situation the nurse has an important role for the care. Many nurses lack of knowledge about how to take care of the bereaved relatives. Aim: The aim of the literature study was to describe aspects of caring for suddenly bereaved relatives. Method: The data for the study were scientific articles found in the databases PubMed and Cinahl and from a manual search.

The decomposition of organic carbon in drained peat soils is a major source of carbon di-oxide in Sweden. A big part of these drained peat soils are used in agriculture and it is a big challenge to slow down their decomposition. It has earlier been thought that less tilling and higher water table levels would decrease the activity of soil microbes and thereby the decomposition, but recent experiments has showed that this has little or no effect. In this bachelor thesis a field experiment was made on drained peat soil with ley, outside Björklinge, Uppsala municipality, Sweden. The experiment was carried out in May 2011. The objective was to develop a method to examine how the net exchange of carbon diox-ide from plant covered peat soil is affected by temperature and photosynthetically active radiation (PAR).

I denna studie har insamling av referensdata över språkförståelse hos treåringar med typisk språkutveckling genomförts. Till detta har bedömningsmaterialet Sofialådan (Westerlund & Öfverholm-Engström, 1995) använts. Sofialådan bygger som flera andra språkförståelsematerial på den s.k. act-outmetoden där man låter barnet agera med föremål efter en given instruktion. Med hjälp av föremålen i Sofialådan bedöms barnets förmåga att identifiera grundfärger och storleksbegrepp, kategorisera, flytta föremålenligt olika prepositionsanvisningar samt att följa flerledade instruktioner.

Syftet med denna studie är att undersöka hur familjebehandlare upplever det att arbeta med FFT-metoden samt de faktorerna som gör den funktionell. Eftersom FFT är anpassad till den amerikanska kulturen som skiljer sig ganska mycket från den svenska, båda i kultur och socialsystem är det viktigt att inte bara utvärdera utifrån modellen men också hur implementering och anpassning av modellen har gått. För att kunna besvara syftet och frågeställningar har fem kvalitativa intervjuer genomförts av semistrukturerad karaktär. Urvalet av respondenter gjordes utifrån snöbollsmetoden där de intervjuade arbetar inom socialtjänstens öppenvård. Resultaten visade att det finns många saker som ska tas hänsyn till vid anpassning till andra kulturer, bland annat utbildningar, målgrupper och ekonomi. FFT är en behandlingsmetod och en påbyggnadsutbildning där gränsen mellan det som är klientens behandling och det som är FFT-terapeuternas utbildning är diffus.

Background: Pain can be a constant problem in many older people's daily life, associated with particular physical and social disability, depression and poor quality of life. Dementia diseases are often associated with old age. Communication difficulties are one of the consequences of the disease, which clarifies the role of nursing staff in detecting and assessing pain. Objective: The aim was to compile knowledge about how nursing staff can identify pain in people with dementia. Method: A systematic literature review, where data were collected through manual and database searches.

The aim of this study was to gain a greater understanding of what social workers perceive to be mentally demanding and emotionally challenging work, and which strategies they use to handle it. I chose to interview six social workers, three of them had long experience of social work, and three of them had worked for less than a year. The justification for this choice wasthat I wanted to interview people with different experience of social work over time, to be able to see possible differences in what was perceived as mentally demanding and emotionally challenging work, and how it was handled. The social workers were interviewed with a semi structured interview manual.The results showed that the organization of the social service is not fitted to the work that social workers execute. This means that what is perceived as mentally demanding and emotionally challenging work largely depends on this.

The IPv6 protocol offers with some new functions, one of them is auto configuration. With auto configuration it is possible for nodes, i.e. hosts and routers, for automatically associated with IPv6 addresses without manual configuration. Auto configuration it is another protocol as it uses Neighbor Discovery protocol (ND) messages (ND is mandatory in the IPv6 stack). The main purpose of ND is that nodes can discover other nodes on the local link, perform address resolution, check that addresses are unique, and check the reachability with active nodes.There are exactly the same vulnerabilities of IPv6 as IPv4 and is now exception, ND if not properly secured.

The search was made in PubMed, CINAHL and by manual search. The articles were reviewed, analyzed and summarized. Results: For newly graduated nurses? experience in end of life care proved to be something new, developing, difficult to manage and frightening, but expected in the profession.

Background: When a child ends up in a hospital the whole family will be affected. The family?s situation can be turned upside down and the daily life can be affected. The nurse needs to have a holistic approach when caring for the child and the rest of the family. For the nurse to be able to provide personalized information and care, they need a relationship with the child and family.

The aim   is furthermore to depict the experience of unexpected and sudden death from the nurse´s point of view. Method: The literature review study has been carried out with a descriptive design. The result of the study was based on 14 scientific articles with quantitative and qualitative approach. The articles were searched in the databases PubMed and Cinahl and through manual search.Results: A majority of close relatives that experience a sudden bereavement are dissatisfied with the way they have been encountered by the staff.

Det här examensarbetet går ut på att utreda vilken påverkan oljeval och inkörningsmetod har på tätning mellan kolvring och cylindervägg i en fyrtaktsmotor. Arbetet har utförts på en motorcykel av märket Honda och modellen heter CBR 954 RR årsmodell 2003. Det diskuteras dagligen i tidningar, på internet och i garage runt om i världen om vilken typ av inkörning som är effektivast för att få en motor att gå bra och hålla länge. Vissa bil- och mctillverkare har helt tagit bort sina inkörningsrekommendationer medan andra fortfarande har kvar rekommendationen att man ska köra lugnt och på låga varvtal under ett visst antal mil. Eftersom att inkörningen påverkar väldigt många parametrar så finns inte möjlighet att testa hur olika oljeval och inkörningsmetoder påverkar alla dessa parametrar.

The aim of this thesis is to compare the effectivity of using a natural language and a controlled vocabulary when performing subject searches in the bibliographic database LISA Library and Information Science Abstracts. 20 topics were created and for each topic two searches were made, one by using a query formulated with natural language directed to the abstract field and the other one by using a query formulated with descriptors from the thesaurus in LISA directed to the descriptor field. The average relative recall amounted to 64,8% for the AB-queries and 54% for the DE-queries. Failure analysis showed that the majority of the relevant documents not retrieved by AB-queries could have been retrieved with other query terms, such as synonyms. In a natural language there are many different ways of expressing a topic, and this tends to have a negative effect on retrieval effectivity.
