På senare år har polisen i Sverige börjat använda sig av spårhundar i sitt arbete för att säkra biologiska spår vid brottsplatser. En hund har tusen gånger mer känsligt luktsinne än människan vilket betyder att hundar kan hitta små biologiska spår, ofta blandade med jord, som är omöjliga för människan att se med blotta ögat. Det ökande användandet av spårhundar har lett till att fler biologiska prThe aim of the project was to investigate and evaluate different extraction methods for detection of human DNA in environmental crime scene samples containing soil. Soil is a complex and heterogeneous material consisting of several inhibitory compounds, which makes it difficult to extract DNA from such samples. The investigation included the evaluation of 19 different extraction methods based on s

The aim of this study was to examine whether visitors to family counseling intended to go to one or more sessions of counseling and whether the expectations and experiences of the first session affect the visitors intention. It was a quantitative study that consisted of two parts, a survey and a structured interview. The participants in the survey answered the survey before their first counseling

I det här examensarbetet undersöks den möjliga tillämpningen av långsamt ljus till laserstabilisering. Stabiliteten av lasrar låsta till externa kaviteter är begränsad av stabiliteten hos moderna i referenskaviteten. Genom att använda dispersiva effekter som ger upphov till långsamt ljus kan den effektiva längden av en kavitet ökas med flera storleksordningar, utan en motsvarande ökning i känslighIn this thesis the application of slow light effects to the area of laser stabilisation is investigated. The frequency stability of lasers locked to external cavities is limited by the stability of the modes in the reference cavity. By using dispersive slow light effects the effective length of a cavity can be increased by several orders of magnitude, without a proportional increase in the sensiti

Head and neck squamous cell carcinoma (HNSCC) is the sixth most frequent cancer worldwide and its high mortality rate highlights the necessity of developing novel therapies. Among the different cancer therapy methods, one of the most encouraging ones is dendritic cell (DC)-targeting immunotherapy, where desired antigens are delivered to DCs via antibodies. In this study, we investigated the freque

“The female chameleon –fashion's importance in identity creating roleplay” focuses on how women are encouraged by fashion- and lifestyle related materials to create different identities and roles in everyday life. In the first part of the analysis it answers how women create roles when they actively engage in the process by seeking advice via different media. To understand identity-constructio

The purpose of this ethnographic study was to examine the conceptions and challenges people deal with that work among the disability community in the country of Georgia. I have analyzed my empiric material through the theoretical framework of stigma and normality, but also through a cultural perspective. My focus was to discover how disabled people are viewed in Georgia, as well as how they view t

I läkemedelsbranschen är renheten ytterst viktig, och ibland kan vissa metoder belasta miljön och omgivningen onödigt mycket. Denna artikel tar upp förslag som med hjälp av ultraljud kan förbättra olika nuvarande rengöringsmetoder utan att öka belastningen på miljön.The cleaning methods after the coating of Nicorette® gums has a few shortcomings. The build-up of residual titanium dioxide on the walls inside the mixer and holding tank is a longstanding issue that needs to be addressed. Another issue in the cleaning process is residual gums in the pan after emptying. These residual gums may interfere and cause a mix-up with the next batch. The current method

Ett av de mest internationellt kritiserade besluten som Europeiska unionen tagit var då de 2008 beslutade att inkludera alla flyg till och från EU i Europeiska unionens handel med utsläppsrätter (EU ETS). Med betydelsen att flygbolagen skulle bli tvungna att handla med utsläppsrätter inte bara gällande de utsläpp som skedde inom Europeiska unionens luftrum utan också utanför. Beslutet resulterade One of the most internationally criticized decisions made by the European Union was the extension of the EU emissions trading scheme (EU ETS) in 2008; so that it would also cover all aviation coming from and going to the EU. The emission trading would cover emissions discharged both outside and within the EU territory. The situation led to a legal battle before the Court of Justice of the European

The right to education in International Human Rights Law has found much discussion in terms of access and compulsion. This right is the only right in the Instruments that carries with it a “purpose” element, which however has been left undefined and under discussed. This study has two layers, the first being to rightly understand the “purpose” element of the right to education. The second is an ex

The aim of this study was to examine how young people define their family and how they describe their own family relations. What makes the family a family from the perspective of a youth? The questions posed were: Who do you include in your family? and What makes family important?. Utilizing a qualitative method known as self-documentary data compilation, young people, aged 15, have written essays

With the increasing importance accorded to environmental performance of buildings, the goal of this master thesis is to study the Dutch assessment method for evaluating the environmental impact caused by the material of an office building project with the Dutch version of the BREEAM certification scheme. After doing a literature review to comprehend the current state of affair concerning the asse

Taste masking is an important aspect in the food industry. Many health beneficial foods contain compounds such as phytochemicals that have undesireable tastes. The aim of this work was to prepare particle-stabilised (Pickering) emulsions to encapsulate and mask the taste of strong flavoured oil using heat-treatment. Quinoa starch Pickering emulsions made with a neutral oil (miglyol), fish oil and

Många dierentialekvationer inom fysik och matematik är kopplade till obegränsade självadjungerande operatorer. Vi skulle vilja formulera en version av spektralsatsen för dessa operatorer. Denna sats är ett känt verktyg från lineär algebra för att förenkla symmetriska matriser. Dock kan vi inte studera obegränsade operatorer med hjälp av de gamla denitionerna och resultaten rakt av. Vi behöver en n

There is no correlation between internal control environment and possibility of internal auditors in detecting fraud. This research tries to find out if there is any correlation between the years of experience of internal auditors and the perception of possibility in detecting fraud and if there is any correlation between the perception of internal auditors in their role and the perception of poss

In what follows, two properties characterizing supplier selection methods, namely, transparency and independence of irrelevant alternatives, will be properly discerned. Consecutively, three hypotheses, concerning the impact these properties have on the procurement outcome, will be suggested. Transparency is presumed to decrease the likelihood of having a locally established winner as well as to in

The main purpose of this paper is to find if there are any differences between the two Scandinavian countries Sweden and Denmark in help institutions for women in prostitution. Buying sexual services has been illegal in Sweden since 1999. There are no similar regulations in Denmark. By employing a comparative study method, information from the two countries have been broken down through content a

Syfte: Beskriva livet på musikfestivaler och förklara vilken funktion de fyller idag. Frågeställningar: Vilka skäl, förutom musiken, har svenska ungdomar till att delta i en festival? Hur upplever besökarna att deras beteende förändras när de befinner sig på festivalen? Hur kan vi förstå festivalen ur ett större, mänskligt perspektiv? Metod: Jag deltog sommaren 2011 i Peace and Love-festivalen i

Magnetkameran är en icke-invasiv metod som används för att avbilda mjukvävnad i kroppen med hög spatial upplösning. Myelinskidan som omger axonerna i det centrala nervsystemet ger upphov till kontrasten mellan vit och grå substans i konventionella magnetkamerabilder. Det är av intresse att detektera nedbrytningen av myelinskidan eftersom förekomst av sådan kan ge en indikation på tidigare stadier Introduction: The axonal myelin sheath is the main cause of magnetic resonance imaging (MRI) contrast between gray matter (GM) and white matter (WM) in the brain. It encloses a small pool of myelin water (MW) with a short T2 of about 15 ms. Common signal equations of MRI sequence assume an instantaneous RF excitation pulse followed by free relaxation. As known from ultra-short echo time (UTE) MRI,

Inom strålbehandling innebär den s.k. åskådareffekten ("bystander effect") ett relativt nytt tankesätt som betonar de biologiska effekterna av strålning på icke-bestrålade celler i närheten av bestrålade celler. Denna effekt har visat sig påverka inte bara de celler som angränsar till det bestrålade området utan även celler på större avstånd. I Lund pågår just nu ett projekt där man villPurpose Intensity modulation of radiation is one of several important conditions to evaluate for full understanding of how cells involved in the bystander effect influence each other when cells are exposed to radiation at low and high dose rates. The aim of this study was to develop and apply a useful and practical dosimetric method for measurement of the absorbed dose to cell cultures exposed to
