Vattenmolekyler är i ständig slumpmässig rörelse som beror på systemets termisk energi, dvs temperaturen. Diffusionsrörelsen kallas även Brownsk rörelse efter den engelske botanikerns Brown, som upptäckte fenomenet på 1800 talet. Människokroppen består till 70 % av vatten, vilket gör det lämpligt att använda MRT för att studera diffusionsegenskaper i biologisk vävnad och för klinisk diagnostik av Magnetic resonance imaging (MRI) is still a fast growing area of research and is an important part of the clinical tools used for diagnosis of various diseases. The diagnostic values of diffusion imaging are well known especially for ischemic stroke in the acute phase. This work concerns whether the apparent diffusion coefficient (ADC) and the full width at half maximum (FWHM) changes when the ima

Denna undersökning rör frågan om vilket inflytande förkastningarna i de tektoniska Polotsk- Kurzeme och Småland-Blekingezonerna utövat på det överlagrande sedimenttäckets och den nutida topografins utbildning. Syftet var att bestämma karaktären av denna påverkan och dess tänkbara orsaker. De huvudsakliga undersökningsområdena utgjordes av Polotskdelen av Polotsk-Kurzeme deformationszonen i norra VThis is a study of the influence of the crystalline basement faults of the Polotsk-Kurzeme and the Småland-Blekinge Deformation Zones on the development of the sedimentary cover and the formation of the present topography. The purpose is to define the character and possible causes of this influence. The key target areas of this study are the Polotsk part of the Polotsk-Kurzeme Deformation Zone in

Populärvetenskaplig sammanfattning: Stenshuvuds nationalpark är en av Sveriges minsta nationalpark. Dess naturtyper är omväxlande och är därmed en av landets mest artrika nationalpark. Området är, trots sina höga naturvärden, inte speciellt välundersökt vad gäller miljöhistoria sett i ett längre tidsperspektiv. Tiden för trädens invandring vid Stenshuvud under holocen (de senaste 11 500 åren) har A palaeoecological investigation of two peat deposits in the national park of Stenshuvud (N 55° 39´ 21´´, O 14° 16´ 06´´), southeastern coast of Sweden, was performed to date the immigration of tree species and study the landscape history during Holocene. The sequences were analysed for pollen and plant macrofossil. The chronology is based on 14 AMS-14C dates of plant macroremains from terrestrial

Industrial Symbiosis (IS) is a tool that may facilitate coordination of the factors necessary to improve resource use efficiency in regional levels. This thesis studies the potential of developing an IS network in rural Portugal, that could support the competitiveness of the local companies, whilst also improving their own and the regions environmental profile. The research is based on a hybrid o

Our paper is a study about youth and their self-images. During our practical training period we found that the problems young people had always were connected with their self-image. We therefore wanted to find out what youth believe influence their self-image. The purpose of our study was to examine young people and their self-images in a perspective of the ecological systems model. Essential issu

Purpose – This paper aims to improve the understanding how entrepreneurs practice inexpensive marketing by utilising human and social capital instead of financial resources. Methodology – This study was conducted following a qualitative methodology. The data was collected in seven semi-structured interviews with entrepreneurs who have made use of inexpensive marketing concepts and methods. We ana

Most of classic psychedelic literature indicate its potential benefit to society and the environment during a time of rapid environmental degradation and climate change– hinting its potential role to sustainability and socio-ecological transformation. There is virtually no study drawing the explicit interlinkages of classic psychedelic research to sustainability science but it is observed that the

This bachelor thesis is based on a fear of a growing consumption behavior where short lived life cycles of products are causing negative affects on our attempts of building long and healthy relationships to products. The work is also based on a hope of designing products that people are able to appreciate over long period of time. What is it that makes people value and appreciate desig

Tidigare forskning har visat att personer som skadar sig själva tenderar att uppleva mötet med vården negativt. Vårdpersonal kan ha negativa attityder till självskadebeteende, och deras möten med patienter kan väcka känslor av frustration, uppgivenhet och oro, vilket kan påverka bemötandet. Studier har framförallt gjorts med sjuksköterskor och läkare, och i betydligt mindre omfattning med psykologPrevious research has shown how individuals who injure themselves tend to have negative experiences from their encounters with health services. Health service staff may have negative attitudes towards Non-Suicidal Self-injury (NSSI) and their encounters with patients may evoke frustration, hopelessness and worry, which may influence their behavior towards patients. Studies have mainly focused on n

Despite its sandy beaches, lush forest, and many sunshine hours, Bornholm was placed on a list along with 23 other municipalities as a peripheral area by Erhvervsstyrelsen in 2014. This designation means that the municipality’s income per capita is less than 90 percent of the national average and over an hour away from a large city. Being called a peripheral area can come with many negative assump

Syfte: Syftet med denna studie är att undersöka unga konsumenters attityder till företags sociala ansvarstagande. Forskningsfrågorna är 1. Hur ser unga konsumenters attityder ut till socialt ansvarstagande? 2. Vilka åtgärder bör tas enligt informanterna, för att förändra konsumenters uppfattning om företag med bristande socialt ansvarstagande?

Our study aims to get a greater understanding of why students choose a social work education and why the education is so popular despite the social service’s negative reputation. We also aim to get an understanding of the student's intended career paths. We used Hans-Georg Gadamer's hermeneutic approach to the study so that we could use our own interpretations of why students made their ch

Mental unhealthiness among school students in Swedish elementary schools has increased in recent years, which is not least seen by various reports and surveys. All schools have different approaches to their equal treatment work, focusing on making the students feel as comfortable as possible. In recent years, norm criticism has gained a greater part in this equal treatment work, which means making

This bachelor thesis deals with the reporting around the demonstration in Gothenburg on September 30th 2017 arranged by Nordiska Motståndsrörelsen (NMR), a Nordic Neo-Nazi movement. After a cultural debate in Sweden regarding freedom of speech and the attendance of the internet based right-winged alternative media Fria Tider on Mässan Bok & Bibliotek, also known as Bokmässan, always arranged a

The ongoing human impact in form of deforestation, urbanization and intense agriculture is affecting the natural hydrology and our freshwater lakes negatively. Both eutrophication and brownification has seen to increase with the ongoing environmental change which can potentially have large impact on our freshwater ecosystems. Using a mesocosm experiment, this study investigates the individual and

The use of area-based approaches in urban regeneration is widely accepted in the European community. As these projects are based on the context of the focal area, there is no one-size-fits-all solution on how to design and implement those. The Eco-city Augustenborg project is an environmentally-led urban regeneration project initiated in Malmö in 1998. Today, fifteen years after the project was in

Utgångspunkten i svensk rätt är att våldtäktslagstiftningen ska skydda varje individs rätt till sexuell integritet och sexuellt självbestämmande. Dagens lagstiftning gör straffbart när gärningsmannen genom våld eller hot tvingat offret eller otillbörligt utnyttjat att offret befunnit sig i en särskilt utsatt situation. Den kritik som riktats mot våldtäktslagstiftningen är att en person är tillgängThe basis of the rape legislation in Sweden is the right of every individual's sexual integrity and sexual self-determination. The current legislation requires that the offender has used force, threat or a situation of exploitation. The critic against the legislation is that a person is available as long as he or she does not make any physical resistance. The presumption will be different with

It just turned out this way - the life stories of six young women confined to a secure juvenile correctional facility The purpose of this paper is to identify risk conditions and protective conditions for a group of girls under secure confinement, based on their retrospective testimonies, and also to examine how these conditions manifest themselves in their statements. The empirical basis for th

One of the biggest question in physics is to investigate the early universe or big bang. 10 µs after big bang, there existed a phase of transition called QGP (Quark Gluon Plasma). In this phase of transition quarks and gluon were free from each other. In normal life neutron and proton consist of three quarks with exchanging gluons. To simulate QGP scientists has built the large accelerator at CERN
