Varför en rädsla för alternativmedicin? : En studie om hur EU?s kosttillskottsdirektiv har implementerats i Sverige.

AbstractVäxjö University, School of Social SciencesBachelor thesisTitle: Varför en rädsla för alternativmedicin? En studie om hur EU?s kosttillskottsdirektiv har implementerats i Sverige.Author: Annica BlomstrandSupervisor: Anne Haglund-MorrisseyThe aim of this study is to investigate the process of legislation and implementation of the directive of the European Union on the food supplements, focused on member state of Sweden.There are two questions in this study: What was the process of legislation in the period when the Directive on the food supplements became established? and How does the implementation of EU?s decision on the food supplements works in reality? In order to answer these questions, two different methods were used. One was qualitative analysis of the available text and the other one case-study (qualitative including interviews)The conclusion is that the implementation has not been successful. The process of legislation has followed its traditional way, which in its turn did not leave so much space to the thorough implementation of the Directive. Unfortunately, this is a process that overlooks citizens and countries with different premises, affected by the decision.Keywords: EU, kostillskottdirektivet, lagstiftningsprocessen, implementering, organisationsteori, fallstudie.

Energianalys av hygieniseringssystem : jämförelse av befintlig pastörisering med integrerad termofil hygienisering på Kungsängens gårds biogasanläggning i Uppsala

The biogas plant Kungsängens gård, owned by Uppsala Vatten och Avfall AB, produces biogas and biomanure from organic household waste, food processing waste and slaughterhouse waste. In year 2012, 4.4 million Nm3 of biogas were produced from 25 200 tons of waste. Before digestion all substrate is sanitized by one hour?s pasteurization at 70°C in order to kill pathogens. Another method, integrated thermophilic sanitation (ITS), is of interest in order to decrease the energy demand.

Skillnader i kungsörnens (Aquila chrysaetos) flyttningsmönster beroende på ålder och klimatfaktorer : En studie för skyddet av kungsörn

This study examines the factors that influence the seasonal movements of Golden Eagles (Aquila chrysaetos), and can thus provide important information that helps to improve the protection of the species. There were two main purposes of this study. First, I wanted to analyze the difference between preferences of juvenile and adult Golden Eagles in their choice of southern or northern hibernation areas. Do younger eagles prefer moving longer distance to southern areas of Sweden? Second, I wanted to investigate how the climate influenced the choice of date of migration in the fall.

Måltiden som lärandesituation i förskolan : en kvalitativ studie om pedagogers syn på barns övergripande och hälsofrämjande lärande i förskolan genom den pedagogiska måltiden

The purpose of my study has been to find out how four preschool teachers at four different preschools looks at the pedagogical meal from a health and overall learning perspective. I also want to examine how, through the pedagogical meal the preschool teacher works to promote children´s learning and give them an understanding of need to safeguard their health. To achieve my aim I set the following questions;What are the different types of learning preschool teachers believe that children can acquire the basis of the pedagogic meal?How do preschool teachers describe their work from the pedagogical meal to benefit children´s overall learning?How do preschool teachers describe their work at the pedagogical meal for the children to gain an understanding of their health?The study is based on a qualitative method with interviews and observations, triangulation. The theoretical approach to this study is based on the socio-cultural perspective to learning and development.

Optimering av biologisk fosfor och kvävereduktion i ett reningsverk för hushållsspillvatten

In connection with Henriksdals wastewater treatment plant (WWTP) a smaller plant is situated called Sjöstadsverket where new methods for wastewater treatment are tested and evaluated in different process lines. On one of the lines experiments with enhanced biological phosphorous removal (EBPR), have been carried out to evaluate if it is a good alternative to traditional chemical phosphorus removal. This thesis evaluates the results from the experiments conducted during fall 2005.The incoming water from Hammarby Sjöstad consists of only household wastewater, which gives a wastewater with high concentrations of nutrients and organic carbon. This is partly positive, because one of the limiting factors for effective biological phosphorus removal is the lack of easily biodegradable organic carbon. The high concentrations of ammonium and phosphorus demand a high reduction to achieve the requirements of outgoing concentration.To optimize the process experiments with different recirculations and different aeration techniques have been made.

Hylasmotivet hos Apollonios Rhodios och Theokritos

An increasing global population and a worldwide growing urbanization has raised the questionabout the future food security in cities all over the world. Peak-oil limits the access to cheap fossilfuels which threatens the global food-supply chain. This has resulted in a larger awareness anddiscussion related to urban agriculture. Growing crops and keeping animals within the city-borderscould be one way of creating a more robust and sustainable food supply for city dwellers. However,to enable an expansion of the urban agriculture many theorists argue that policies and institutionalstructures that supports and promotes city farming have to be developed.

Ohållbar marknadskommunikation av seriösa hållbarhetsaktörer: en fallstudie av H&M och Max

Problem: Företag ägnar sig åt ett seriöst hållbarhetsarbete, men det finns anledning att tro att detta inte speglas i deras marknadskommunikation. Förändringar i marknadskommunikation tenderar att vara konservativa, då företag väntar på en indikation från marknaden för ökat intresse av hållbara produkter.Syfte: Huvudsyftet med arbetet är att undersöka huruvida företag inom ?fast fashion?- och ?fast food?-industrierna som gör ett gediget hållbarhetsarbete också använder en marknadskommunikation som är ohållbar. Som en del av detta arbete kommer en grundläggande definition av ohållbar marknadskommunikation att konstrueras genom teoristudier.Metod: En kvalitativ undersökning har använts, då en fallstudie med bildanalys har genomförts, med empirisk data hämtad från företagens marknadskommunikation.Teori: Den teoretiska referensramen grundar sig i teorier kring marknadskommunikation, hållbarhetsaspekter och konsumtionssamhällets konstruktion.Resultat: Det empiriska materialet redovisas genom fallstudieberättelse, baserad på bildanalysen av marknadskommunikationsmaterial som utförts och den analysmodell som har konstruerats.Analys: Empiriska data som insamlats har jämförts med de teorier som vi använt oss av i den teoretiska referensramen. Resultaten har analyserats för att hitta övergripande likheter inom företagens marknadskommunikationSlutsats: Företag inom ?fast fashion?- och ?fast food?-industrierna som arbetar seriöst med hållbarhetsarbete kan också använda en ohållbar marknadskommunikation enligt den definition som har konstruerats..

Evaluation of specificity of a walnut antiserum and detection of English walnut (Juglans regia) in food with ELISA and Real-Time PCR

Nuts of all kinds are common ingredients in food. For nut allergy sufferers the frequent use of nuts cause problems and "hidden" nuts in food products may elicit allergic reaction when such foods are consumed. Methods for detecting and quantifying walnut (and other nuts) with high sensitivity and specificity are therefore very important.The objective of this project was to verify the specificity of a rabbit antiserum against walnut with immunodiffusion and to determine the size of the dominant walnut antigens with Western blotting. In addition, a commercial sandwich ELISA for walnut quantification was validated and compared with a qualitative real-time PCR.The rabbit antiserum proved to be less specific but after absorption with cross-reacting nuts and seeds it showed high specificity. The ELISA kit reacted, except for walnut, with pecan and slightly with other nuts and seeds tested.

Egenkontroll i livsmedelsbranschen utifrån verksamheternas perspektiv : en kvalitativ studie

Verksamhetsutövare inom livsmedelsbranschen har ett ansvarar för att den mat som producerats är säker. År 2009 gjordes ändringar i den svenska livsmedelslagen där bland annat kraven försvann på att verksamhetsutövare måste ha skriftliga rutiner och dokumentation (Lindblad, Westöö, Lindqvist, Hjertqvist & Andersson, 2009). Oavsett om verksamhetsutövarna har skriftliga rutiner och dokumentation eller inte måste de kunna bevisa att de har tillräcklig kunskap för att arbeta med livsmedelshantering. Genom ett fungerande system för egenkontroll, alltså en egen kontroll av verksamheten, skapas säkra livsmedel och risken för matförgiftning minskar (Israelsson, 2006). Syftet med denna studie är att undersöka verksamhetsutövarna inom livsmedelsbranschens uppfattning om egenkontroll.

Bok- och grankonkurrens i Sydsverige - markegenskaper och naturlig föryngring :

In southern Sweden, beech (Fagus silvatica) and spruce (Picea abies) are two species with similar demands on soil properties. With increased global warming and high acid deposition the future may bring larger areas were the two species are overlapping, competing for the same soil. The aim of this study was to compare spruce and beech concerning distribution, cultivation and soil properties. From available data comparisons were made between spruce and beech forests in Sweden. Soil analyses were made on samples from beech forest in southern Sweden, with and without natural regeneration of spruce.

Urban agriculture : experiences from the Swedish horticulture

Urbanisation has increased the distance between the urban and the rural. Urban agriculture can be a solution to overcome that distance. The characteristic of urban agriculture is the intensive production in intra urban and peri-urban areas. Until 1950s food production in cities was an important part of the urban economy and the urban food supply. Since the 1950s the urban located production of food has almost ceased in Sweden, partly as a result of cheap food imports.

Elproduktion med ORC-teknik ombord på fartygsserien MK II.

Given that the oil prices have risen and the environmental regulations has become more stringent, the interest in operating efficiency has increased. The project has investigated the possibility of producing electricity from waste heat generated in the diesel process. One technique to utilize and convert energy into electricity is the ORC (Organic Rankine Cycle). This process is based on the Rankine process (the steam process), the difference from the traditional Rankine process is that instead of water as a working medium, an organic substance is used. The main component used in the process is a evaporator, a turbine, a condenser and a pump.

Hundfoder mot hjärnans åldrande ? kan det fungera?

Due to better nutrition, veterinary and overall care, pet dogs? lifespan has increased. With more old dogs we see more health problems associated with age, among those cognitive decline, leading to deficits in learning and memory, disorientation, anxiety and other altered behaviors. Cognitive decline can have severe negative impacts on the life of both dog and owner, when the dog for example forgets being housetrained or starts being awake at night. Two pet food manufacturers have developed food with specific ingredients in order to improve cognitive functions or delay the onset of cognitive impairment. Hill?s Pet Nutrition has developed a dog food with supplements of a broad spectrum of antioxidants and mitochondrial nutrients, aiming to diminish oxidative damage in the brain, thereby maintaining brain function and improving learning ability.

Miljövärdeflödesanalys av Risifruttiproduktionen : En utvärdering av värdeflödesanalys och miljövärdeflödesanalys

This report is the result of a thesis work carried out on the Risifrutti production at the company Procordia Food AB. The thesis is at a master level and is the final work for the author to receive a Master of Science in Innovative production at Mälardalen University. The thesis comprises 30 credits and has lasted for 18 weeks. The thesis is mainly a research on whether it is possible to perform an Environmental Value Stream Map (E-VSM) in a food processing industry and an evaluation if the tools E-VSM and Green Performance Map (GPM) are useful in this type of industry. An extra part to this research is to use the results from the E-VSM and give Procordia Food AB information on improvement potentials in the Risifrutti production. The author has found it difficult to collect some of the quantitative data to the E-VSM, mainly regarding energy, but by using the Value Stream Mapping (VSM) tool and other Lean tools the author was able to identify and quantify several wastes in the Risifrutti production. Recommendations for improvements based on these wastes have been given to the company. In the research part of this report the utility of the Value Stream Map, Environmental Value Stream Map and Green Performance Map in a food processing industry have been analyzed. The author has found that the Value Stream Map has been a useful tool since waste and unevenness in the tact of the production has been identified. The Environmental Value Stream Map and the Green Performance Map are also great tools when a company wants to analyze their environmental impact and then invest in environmental improvements. However, no profound energy analyzes has been done in the Risifrutti production because of the lack of energy meters for steam, electricity and compressed air in the production lines..
