Stevia is a natural sweetener with increasing use in known products, for instance Coca Cola Company launched a new brand called "Life" were they use Stevia as a sweetener. In this work, we have attempted to separate and analyze the different compounds that give the sweet taste, known as steviol glycosides, by ion-exchange chromatography with pulsed amperometric detection. The known metho
Title: Practicing service work without a shield - A qualitative case study on employees’ experiences of interactive service works Submission Date: 23rd of May 2014 Course: Master Degree Project in Managing, Peoples Knowledge and Change Authors: Annie Hansson and Erica Samuelsson Supervisors: Jens Rennstam and Stephan Schaefer The department of Business and Administration School of Economic
In this thesis, different aspects of the quantum Szilard engine are studied using the configuration interaction method. The engine is modelled as a one-dimensional infinite well. The effects of a contact-interaction are examined and it is found that attractive contact-interactions can improve the work output at certain temperatures of an engine that has bosons as a working medium. The role of im
Parkinson’s disease is a neurodegenerative disorder that results in the death of dopaminergic neurons. The death of dopaminergic neurons results in motor deficits of which bradykinesia, resting tremor, and rigidity are the principal symptoms. In addition to the motor symptoms, PD patients often experience disturbances to their gastrointestinal systems. These symptoms often appear years before the
The focus of this thesis is to explore why petty corruption dominates and persists in Bosnian society despite the major anti-corruption efforts of Bosnian government and international organisations. By approaching corruption from a social-legal perspective, this thesis aims to explore the local experiences, social norms and morality of informal transactions in Bosnian society. To investigate these
Background: Rat pups are born with an immature intestine adapted for the effective uptake of milk nutrients and with high permeability for bioactive molecules from the maternal milk until weaning. During weaning the immune system is activated after stimulation with e.g. dietary antigens, leading to an inflammatory response in the gut. This response is believed to be important for progress of gut m
City densification in Sweden has decreased the amount of green areas in Swedish cities. This undermines the existing ecosystem services that could for instance provide climate change mitigation and adaption. Green roofs are considered to be a product that can strengthen or substitute the urban ecosystem services produced by natural vegetation. This paper investigates whether retrofitting green roo
Notwithstanding the increasing environmental awareness among consumers, researchers do not witness a substantial shift in consumption and disposal behaviour of textiles. Since research on disposal behaviour of home textile products is currently limited, it is relevant to explore consumers’ decision-making when handling no-longer-wanted home textiles. This thesis aims to better understand consumers
Speed and visual influence on fashion trends – a study of Snapchat’s impact and significance on the spread of trends in the fashion system through visual images. Today’s fashion system has reached its climax due to technological advances and increasingly speedy nature of how fashion trends are conveyed to consumers. The tool used to examine the thesis of this study was a qualitative text analysis
Det är vanligt att bedriva ett mångfaldsarbete i organisationer idag, men dess omfattning och definition är ofta otydlig. Jämställdhetsarbetet tenderar att läggas till som en del i mångfaldsarbetet. Därför är det intressant att undersöka hur jämställdhets- och mångfaldsarbetet fungerar ihop, och vilken plats jämställdhetsarbetet får i mångfaldsarbetet. För att ta reda på det undersöktes tre kommun
In this work aMatlab model of a simplified LTE system has been implemented. The PUSCH and PDSCH signal chains has been used for reception and transmission of data and DM-RS symbols are used as pilots. Moreover, the model supports communication and interference between multiple users and base station antennas. The wireless channels are modeled as multi-path Rayleigh fading and are continuous in tim
Background. The United States has been a diverse country since it is establishment. The effects of socioeconomic characteristics including immigration, age, employment status, educational attainment on total fertility rate have been discussed in the previous studies. Objective. The objectives in this study are to explore whether the difference in the timings of first childbirth among Hispanic wome
Klarspråk är ett språkligt koncept som myndigheter kan tillämpa i syfte att göra sina texter vårdade, enkla och begripliga. På så sätt antas myndigheten kunna uppnå kraven i Språklagen. I denna uppsats testar jag effekter av klarspråk på ett nytt sätt: genom ögonrörelsemätningar och två typer av intervjuer studerar jag samspelet mellan en specifik typ av mottagare och en specifik typ av myndighets
Antimicrobial peptides (AMPs) are evolutionarily ancient molecules. They are essential innate immune response molecules that protect organisms from invading pathogens. Tissue factor pathway inhibitors (TFPI-1 and TFPI-2) C-terminal derived peptides exert host defense mechanisms against microbes. Studies showed that in human plasma, C-terminal TFPI-1 and -2 derived peptides mediate bacterial killin
The continued increased exposure to chemicals and the increasing prevalence of allergic contact dermatitis makes it important to develop accurate testing methods and strategies to assess chemical sensitizers. The Genomic Allergen Rapid Detection (GARD) assay is an in vitro test method that uses the transcriptional response of a myeloid cell line, MUTZ-3, after exposure to test substances to assess
Based on readings, news and experiments this project is a creative exploration of data collection in the age of Internet. The disclosure of government online surveillance programs in 2013 raised questions about the power of data collection by governments and companies. Although this was big news when it happened, the topic is not as discussed or as acted on as it should be. Has anything changed si
As volumes of e-waste (WEEE) are increasing worldwide, the environmental and health impacts caused by this waste stream are leading to rising concern over how it is managed and disposed of. In the European Union this has been addressed by the WEEE Directive, a policy requiring all Member States to have a system for managing e-waste. The revised policy (Directive 2012/19/EU) sets increasingly ambit
Endowed with diverse vegetation covers, the Middle Atlas Mountains receive substantial snowfall in winter, which contributes to plant hydration during the growing season. Using remotely-sensed imagery, this study aims to assess the trends in snow cover variations between 2000 and 2015, analyse the local influence of snowpack persistence on vegetation growth and evaluate the significance of this ef
