International agricultural trade has seen big developments throughout time, initially driven particularly by the industrial revolution and then influenced by globalization and changes in technology. Coupled with decreasing barriers to trade, the rise of trade agreements, and economic growth of countries, international influences are having big effects on food consumption patterns. In particular, w
Att byta ut fullt funktionella klädesplagg och möbler eller renovera ett hem för nöjes skull är inget uppseendeväckande idag. Att konsumera är normen. En stor del av de miljöproblem som finns beror dock på den utarmning av naturresurser som sker för att tillgodose samhället med detta flödet av varor. Dessutom leder konsumtionen till att stora mängder avfall genereras. En del av lösningen till dess
The European Spallation Source, ESS, is set to become the world's brightest spallation neutron source. Spallation neutron sources present unique challenges with regards to radiation shielding due to the creation of a significant number of high energy neutrons during nuclear reactions in the spallation target. These can reach up to the energy of the driving proton beam. Performing Monte Carlo s
With rising privacy concerns of individuals, the EU parliament actively starts protecting the privacy of its citizens with enforcement of the GDPR. This study examines if enforcement of GDPR will lead to an individuals’ lower privacy concerns and higher trust beliefs with regard to E-commerce companies. The APCO framework is followed. Besides using already existing constructs within this framework
Den stressrelaterade ohälsan har ökat såväl i Sverige som i övriga världen och däribland utmattningssyndrom som har ett långvarigt läkningsförlopp. Det pågår på olika ställen intensiv forskning kring vad som kan förändra och påverka sjukdomsförloppet vid utmattningssyndrom. Forskningen fokuserar i huvudsak på arbetsåtergång som mål med behandlingen. Syftet med denna kvalitativa studie var att undeStress-related illness has increased both in Sweden and abroad, among it burnout syndrome, which has a prolonged healing process. Intense research is carried out worldwide on which factors can change and affect the course of the illness. The research is mainly focused on return to work as a goal of the treatment. The purpose of this qualitative study was to investigate both patients’ and psychothe
The Water Tightness group at Volvo Cars is responsible for creating and maintaining requirements and thresholds regarding water flows on a car. This is performed by doing extensive physical testing while making sure that databases and previous requirements are kept up to date. Previously the big focus for the Water Tightness department has been physical testing as there were no other options. Dur
Concrete has been frequently used as a buildning material in modern time and is today one of the most applied buildningmaterials. Since the demand of sustainability is getting bigger, more focus is put on the large carbon dioxide emissions that happens due to the cementmanufacturing. One way to reduce the carbon dioxide emissions is to replace a part of the Portlandcement with residues from other
The aim of this study is to illustrate the complex phenomena of workrelatad violence within the emergency care, and explain the phenomena by applying a perspective of sociology of law. Our interest emerged from the frequent reports about emergency personnel being threatened and abused by patients. Our main question is: "How do healthcare personnel perceive work related violence?”. We used the
Denna studies syfte är att undersöka hur fyra trumslagare använder sig av inspelningsteknik i sin undervisning och sin egen övning samt hur det påverkar lärandet. Detta har undersökts genom semi-strukturerade intervjuer med fyra informanter som alla har undervisat på estetiska program och högre musikutbildningar. Utifrån litteratur beträffande användningen av inspelningsteknik i skolan och hur manThe purpose of this study is to investigate how four drummers use recording in their teaching and in their individual practice and how this affects their learning. This has been investigated through semi-structured interviews with four informants who have all taught on arts programs in school and higher music education. Based on literature regarding the use of recording equipment in school and how
Syftet med denna studie är att undersöka hur några av dagens sångpedagoger upplever att populärmusikaliska sångideal påverkar sångundervisning på gymnasiet, samt hur pedagogerna arbetar för att hjälpa elever att lära känna och förstå sin egen sångröst. Studien har genomförts med hjälp av fyra kvalitativa forskningsintervjuer med sångpedagoger som undervisar på gymnasiet. Litteraturgenomgången belyThe aim of this study is to examine how some of today’s voice teachers believe that vocal ideals in contemporary popular music affect voice tuition in upper secondary school, and how the teachers guide voice students to know and understand their singing voice. This is a qualitative interview study, with four voice teachers from upper secondary shools. The literature review illustrates which elemen
To optimize precision and accuracy of small dispensed volumes, a dispenser was built. A 96-well plate was loaded with four replicates of a linear pyranine dilution series to test the accuracy and precision of the dispenser machine. Three dilution series of pyranine (100-0 percent, 10-0 percent and 1-0 percent) were made. The results showed that the dispenser has very good accuracy and precision. T
Bacteria play a major role in biogeochemical cycles in the ocean. Bacteriophages are estimated to cause the deaths of more than a fifth of all marine bacteria every day and the dynamic between bacteria and virus therefore have huge ecological impact. CRISPR-Cas systems work as an adaptive immune system for bacteria that protect them against viruses. Spacers acquired from viral sequences can make t
In line with the Paris Agreement and the aim of keeping the globally averaged surface temperature at a maximum increase of 2°C, Sweden implemented the Swedish Climate Policy Framework. It consists of three pillars; new climate goals, a climate act and an independent climate policy council. The framework is the first of its kind in Sweden and provides long-term goals and an obligation to continuous
Spatial transcriptomics is a recently developed method for analyzing the transcriptome while conserving the spatial information. Albeit not with single resolution as of now, it has a big potential for application in tissues in which the exact spatial information of gene expression is crucial. One of those cases are brain transplants aimed for replacing lost cell populations, e.g. in stroke or neur
The high sex ratio at birth and its gradual increase are one of the most significant demographic changes in China in the past 30 years. The sex ratio at birth first increased until 1994 and then stayed fluctuating before it decreased from 2000 on. Regarding the issue of whether or not China's current family planning policy affects and to what extent it affects the sex ratio at birth, starts wi
In this thesis, the space--time picture of the hadronization model has been implemented in the event generator Pythia. From this implementation, the hadronic behaviour has been studied for different scenarios, in order to begin addressing the unexpected collective behaviour of high-multiplicity pp events, which is typical for heavy-ion collisions. First, the temporal and radial evolution of pp and
This study analyzes hedging maturity structure and examines the relation between the maturity structure of corporate hedging and debt characteristics. The purpose of the study is to provide new insights in what determines the hedging maturity and discover new aspects of companies hedging positions, which still is an unexplored area of modern risk management theory. The objective of the paper is to
Quantification of CO2 emissions for case 1 - ISLK and case 2 - Föraren arrived at 42 and 125 CO2 per A_temp and with suggested changes it was possible to reduce to 38 and 109 CO2 per A_temp. The review of the possibility of lowering emissions in the manufacturing of concrete showed that the addition of fly ash reduced CO2 emissions by 10% per 10% of cement exchanged for fly ash. As well as demonst
This thesis covers established procedures for the successful and attempted immobilization of lipases and phospholipases to various hydrophobic support materials, utilizing a rotating bed reactor, magnetic stirrer and tube-rotator. The design of a robust platform was established with great instrumental knowledge and proper conditioning for the creation of efficient immobilizations and activity assa
