This thesis work has been performed at the department of diagnosis and dependability at Volvo Car Company, Torslanda. The background of this project is based on interest in ascertaining how different factors possibly can affect a diagnosis method, which has been developed to find leaks in the fuel tank and evaporation system. According to the OBD II requirements leaks with an orifice diameter larger or equal to 0,5 mm, must be detected. The idea of the diagnosis method is to create an over pressure in the system with an air-pump. The current through the pump is measured and correlates to the power consumed by the pump.

Mellan år 1987 och 2000 fanns ett beväpnat helikopterförband inom arméflyget. Dessa två pansarvärnshelikopterkompanier användes för att bekämpa stridsfordon. Efter nedläggningen har Sverige inte haft en helikopter med beväpning för annat än egenskydd.Uppsatsen syftar till att utifrån William S. Linds teori om manöverkrigföring utvärdera om pansarvärnshelikopterkompanierna framgångsrikt bidrog till att besegra motståndaren.Det framkommer att pansarvärnshelikopterkompaniernas taktik väl stämmer överrens med Linds teori vilket pekar på att bestyckade helikoptrar är ett mycket användbart instrument inom manöverkrigföringen.  .

My purpose in this work was to find out how staff in a middle sized school uses its local Equal treatment plan in its work against bullying. But also to see how the use of a standardized anti-bullying program works to prevent bullying. I have interviewed the principal, teachers, and what we in Sweden call a ?fritidspedagog? and the members of the anti-bullying team to get answers to my questions.  The conclusion of this study is that the school follow and work according to what the Equal treatment plan states, both in terms of prevention, as in working with actual bullying cases. The school has also followed the National School Agency's recommendations on what should be the local Equality plan, but also to follow up and revise it each year. The interview shows that the staff at the school placed great emphasis on talking and discussing with students about how to behave towards each other, they also brought up things that happened at one time and talked about this. The staffs were very committed to work towards the prevention of bullying and the same was true with the school's headmaster.

An increasing number of heat pump producers have developed heat pumps that can be connected to solar panels. In this thesis we have examined the possibilities of connecting solar panels to existing ground source- and geothermal heat pumps that has not been adapted to solar panels. During the work process, a prototype plant has been built to compare our theory with the practical results and with our designed sizing tool. The work has rendered in knowledge that will be used to build a sun module that can be easily connect to the existing heat pump system. The existing heat pump, our test plant, has been supplemented by an advanced storage tank used to allow different operating modes.

Today is one of the goals with zoos to conserve endangered species and some animals may also become reintroduced. But behaviours can change in generations of captive animals because of environments that differ from the wild. Animals must then be prepared before being reintroduced and predator training enhances the animal?s chance to survive in the wild. When training animals to avoid predators it is often necessary to use frightening stimuli.

Vectors based on lentivirus backbones have revolutionized our ability to transfer genesinto many cell types. Lentiviral vectors integrate into the chromatin of target cells and do not transfer any viral genes causing vector replication. Both of these features arecommonly used in gene therapy and have been used clinically in individuals sufferingfrom cancer, infections and genetic diseases. It has been discovered that T-cells can be genetically modified to be used as effective weapons against cancer: therefore virus mustbe produced to deliver the gene of interest into the T-cells. In this project, lentiviralvectors have been produced to transfer the gene coding for a chimeric antigen receptor(CAR) which is directed to CD19 on B-cells.

Samtidigt som svensk forskning visar att individer med utländsk bakgrund blir utsatta för diskriminering och stigmatisering så väljer allt fler ungdomar ur denna grupp att högskoleutbilda sig och visar en benägenhet att välja elitutbildningar. I denna uppsats undersöks om det finns ett samband mellan vetskapen om, eller erfarenheter av, diskriminering och elitutbildningsval. Den metod som används är semi-strukturerade intervjuer med fem kvinnliga och fem manliga juriststudenter med ursprung i Mellanöstern. De teoretiska utgångspunkterna är sociologen Erving Goffmans teori om stigma, sociologen Michèle Lamonts teori om destigmatisering och socialfilosofen Axel Honneths teori om erkännande. Resultatet visar att juriststudenternas föräldrars erfarenheter av diskriminering och egna erfarenheter av exkludering har lett till en hög studieprestation där elitutbildningsvalet kan ses som en anti-diskrimineringsstrategi.

Maligna tumörer är något som drabbar såväl djur som människor över hela världen. Därför har stora ansträngningar lagts på att kartlägga mekanismerna bakom en av nyckelparametrarna för tumörtillväxt, tumörangiogenes. Studier har visat att tumörcellerna själva kan inducera neovaskulatur genom ökat uttryck av pro-angiogena faktorer, så som endotelial tillväxtfaktor och angiopoeitin-2. Anti-angiogenesterapi, i form av olika antikroppsderivat, riktar sig fram för allt mot de signalvägar som involverar pro-angiogena faktorer i ett försök att stävja tumörens tillväxtresurser. Idag används främst monoklonala antikroppar, var för sig, tillsammans eller i kombination med kemo- och/eller strålningsterapi. Tyvärr är anti-angiogenesresistens är ett växande problem, troligen relaterat till både adaptiva och inbyggda resistensmekanismer hos de tumörceller som behandlas.

Drug related messages in antidrug campaigns and music related media -A qualitative study about young people?s perceptions Youth are exposed to both promotional and critical drug and alcohol messages in their daily media consumption. The purpose of this study is to examine how youth perceive anti-drug campaigns and drug-promoting messages in music-related media. The empirical material consists of qualitative data, including a focus group and two individual interviews, consisting of youth between the ages of 18 and19. One main finding is that young people perceive anti-drug messages differently, yet they are virtually unanimous about what makes such messages effective.

Sveriges ytstridskrafter hade länge en förmåga att hävda sig mot fiendens stridskrafter ute till havs på 1950- och 60-talen. Nedrustningsprogrammet av försvaret på 1960-talet innebar att teknikutvecklingen bromsade upp och flottans större fartyg kryssare, fregatter och jagare skulle bytas ut till en lätt flotta med små snabba enheter. Detta resulterade i att flottans taktik anpassades till ett tillbakadraget uppträdande längs med kustbandet och inom skärgården. Svenska officerare bevittnade på när Sovjetunionen rustade upp och utvecklade nya vapen och fartyg med robotar av högsta kvalité i Östersjöområdet. Detta hot medförde att officerarna i flottan ville satsa på ett långräckviddigt vapen för att bli mer jämbördig mot fiendens styrka ute till havs.Resultatet blev en svenskutvecklad sjömålsrobot, Robotsystem 15 (RBS 15), som infördes i marinen i början av 1980-talet.

LGBT people, in Uganda, have since the colonial time been in a vulnerable situation. When the President signed the ?Anti-Homosexuality Act? into law 2014 all forms of same-sex relationships became criminalized. The time after the law passed have been characterized by an increased homophobia and further violence against LGBT people. These are seen as deviants since they do not live according to the social norms, that the right thing to be is heterosexual.

Syftet med denna uppsats är att undersöka om de grundläggande förmågorna är relevanta även i en anti-terrorist operation, då förmågorna hittills varit ett begrepp inom mellanstatliga konflikter. För att besvara detta används två frågeställningar:? Är de grundläggande förmågorna relevanta för denna typ av operationer?? Vilken eller vilka av de grundläggande förmågorna låg till grund för framgång/misslyckande i operationen?Studien genomförs som en jämförande fallstudie där fyra operationer av militär och polisiär karaktär analyseras utifrån de grundläggande förmågorna. Data erhålls genom textanalys av historiska skildringar som avhandlar respektive operation.Resultatet av studien visar att de grundläggande förmågorna är relevanta för anti-terrorist operationer och tillämpningen av dem kan bestämma utfallet av operationen. De förmågor som låg till grund för en lyckad eller misslyckad operation är verkan, skydd, und/info och ledning..

This thesis describes the development of a tank insert for diesel cars, from idea to a prototype. The idea is to design an insert which makes it impossible to refuel petrol in a diesel car. The insert shall be installed in the existing tank opening on diesel cars. The tank insert is designed for the Swedish company SverigeGrepen AB located in Vänge, just outside Uppsala. Their main product is a pitchfork that is ergonomically designed and durable.A pre-study were performed in which information relating to fuel caps, tank openings, petrol- and diesel nozzles were collected.

The subject of the essay is about a society called Klippan and the existing conflicts there between an active racist group and some youths with foreign heritage. The essay also concerns issues like racism, its effects and how it is expressed at different levels in a society. Futhermore we discuss how a community can prevent 'subtle' racism and open declared racism and how to work in a racist manner. We also talk about which role the immigrant youths play in the conflicts and how their behaviour can be understood. Another perspective that is discussed is which aspects can affect individuals to join an active racist group and which factors can make them leave such a group.

A study of communication content, frequency and problems was performed at the Swedish Air Force Air Combat Simulation Centre, FLSC. The purpose was to investigate the connection between team communication and performance variables, to study communication problems during air combat and to employ and develop the PILOT method of communication problem analysis. Ten fighter pilots and four fighter controllers engaged in simulated air combat beyond visual range in teams on two sides, Blue and Red, with four pilots and one fighter controller each. Eight such training runs lasting 15 to 25 minutes were analyzed with regard to the Blue team?s communication during launch situations, i.e.
