Ett trendigt kretslopp : en studie om konsumenters attityder kring att lämna in sina avlagda kläder till modebutiker

I samband med att konsumtionen av kläder och textilier ökar i världen slängs också allt mer kläder i hushållssoporna. Studier visar att den genomsnittliga svensken köper cirka 15 kg kläder varje år varav hela 8 kg hamnar i soporna. Endast 20 % av det totala textila avfallet återvinns. Trots att återvinning av textilier visat sig ha mer miljönytta än till exempel återvinning av tidningspapper så finns i dagsläget inget producentansvar för textilbranschen, vilket gör att all insamling av textilier sker på frivillig basis genom bland annat välgörenhetsorganisationer. Oavsett om ett producentansvar kommer att införas för branschen i framtiden eller inte krävs att samtliga parter, både konsument och producent engagerar sig i processen för att insamlingen ska fungera.

Automatisk bullerdosreglering i hörselskydd

På bullriga arbetsplatser använder personal ofta hörselskydd med inbyggda högtalare för att lyssna på exempelvis musik i underhållningssyfte. Om användaren lyssnar på höga ljudnivåer under långa perioder kan bullerskador uppstå i dennes öron. Enligt lagstiftning måste nivån därför begränsas i förebyggande syfte.Bullernivån är ett genomsnitt av de ljudnivåer användaren exponerats för under en arbetsdag. Användaren måste vila öronen om gränsvärdet för bullernivån nås.Om man utnyttjar att det är ett genomsnitt kan användaren tillåtas lyssna på en hög ljudnivå under en begränsad tid för att sedan sänka den. Det går att bevara både säkerheten och lyssningsupplevelsen om en sänkning införs långsamt.Detta arbete beskriver hur en algoritm till en digital signalprocessor kan konstrueras för att reglera ljudnivån.Målsättningen var att algoritmen skulle skydda användarens hörsel utan att försämra lyssningsupplevelsen, och utan att förbruka mer energi än nödvändigt.I algoritmen ingick en prediktor som predikterar mängden buller användaren riskerar att utsättas för, om denne fortsätter lyssna på samma nivå.Långsamma sänkningar av ljudnivån kan då utföras i tid innan gränsvärdet nås.Det visade sig att algoritmen endast behövde ett fåtal samplingar per sekund för att skatta och reglera ljudnivån tillräckligt precist, vilket reducerade energiförbrukningen.Resultatet visar möjligheten att kombinera målen för säkerhet, lyssningsupplevelse och energieffektivitet i hörselskydd.Algoritmen implementerades inte på ett skarpt system.Den hade enbart tillgång till ljudsignalen användaren ämnade lyssna på i underhållningssyfte..

Emerging zoonotic viruses : what characterizes them and what are the risk factors for their emergence?

Emerging infectious diseases poses a great future threat, not only to humans but also to domestic animals and wildlife. Even though the majority of these infections only cause minor health problems, the relatively recent emergence of HIV clearly illustrates that the next major human pandemic may surface at any time. Regardless of what the name indicates, most emerging human pathogens are not believed to be recently evolved, but to have existed previously in the natural environment. Most emerging pathogens are zoonotic, i.e. able to infect animals besides humans.

Kan D-vitamintillskott minska depressiva symtom?

Background: Sweden is a country where vitamin D deficiency seems to be common, partly because of its geographical position, which reduces the availability of UVB radiation, but also that people avoid sunlight due to increased skin cancer risk. Research shows that vitamin D plays an important role in the prevention of many diseases such as cancer as well as autoimmune and neuropsychiatric diseases.Vitamin D is a fat soluble pre-hormone and a collective name for closely related compounds which act as hormones after undergoing a transformation in the body.Humans can utilize vitamin D through diet and produce it in the body by exposing the skin to the sun. Previous observational studies and epidemiological studies have established a hypothesis that there seems to be an association between vitamin D supplementation and reduction of depressive symptoms.Objective: The aim of this study was to investigate if vitamin D supplements may decrease depressive symptoms.Methods: This work is organized as a literature review and article search is made in the database PubMed in January 2012. Keywords used were ?vitamin D and depression? and inclusion criteria were: randomized clinical trials, be conducted on humans, written in English.

Basel II och fastighetsbranschen - en scenariostudie av de nya kapitaltäckningsreglernas konsekvenser för fastighetsbranschen

Banks carry a great responsibility when it comes to the financial systems in our society. Disturbance in the credit system affects both lender and borrower. All financial institutions must therefore carefully estimate their risk exposure. This assessment enables them to cover themselves from losses with appropriate capital buffers as main guardian. In order to prevent bank crises and also to maintain financial stability in general, new regulations concerning analysis and preventive actions were introduced on the 1st of February 2007.

Fast fashion kontra hållbar konsumtion : En studie om konsumenters attityder kring ekologiska produkter i fast fashion företag

Klädindustrin har förändrats betydligt de senaste 30 åren. Detta har lett till nya affärsmodeller som bygger på trendigt, billigt och snabbt mode. Dessa affärskoncept benämns fast fashion och i Sverige finns kedjeföretagen H & M, Lindex och Gina Tricot för att nämna några. Konceptet uppmanar konsumenter till att ständigt konsumera kläder som därmed stimulerar konsumenternas behov av att bära det senaste modet till ett rimligt pris. Detta beteende får i längden konsekvenser för miljön vilket leder till att media och samhällsaktörer ifrågasätter dessa affärsmodeller.

Småskalig utsädesproduktion : ekonomiska och organisatoriska aspekter

The economic situation in the Swedish agricultural industry is currently experiencing a development towards larger units. This progress occurs simultaneously as farmers in cooperation more frequently make investments to decrease risk exposure and to improve the financial result. The purpose with this thesis is to study which advantages and problems a group of farmers experience after a common investment in a small-scale seed production. The aim with this investment is to increase the level of vertical integration in their respective agricultural firms and the results will be analyzed from an economic point of view. At present, the farmers are all seed producers with considerable cultivation areas.

HipHopvideor : Från idé till färdig produkt

Vi, Anna Nilsson och Jeanette Svensson, valde att producera musikvideos under vårat kandidatarbete på Blekinge tekniska högskola. Detta eftersom vi båda har ett stort intresse till musik och rörlig bild. Vi valde att göra två stycken för att lära oss produktionens process grundligt och för att nu kunna jämför de båda och av detta ta lärdom. Den ena musikvideon gjorde vi till en skånsk duett som heter KC och den andra till Advance Patrol. Båda låtarna är inom genren hiphop.

Fuktsäkert byggande : Sjönära bostäder i Östra Hamnen i Västerås

Housing construction very close to the lake Mälaren has become very popular today. One potential problem with these houses is the influence of the sea climate. Unprotected buildings are affected by strong winds and precipitation. So for that reason, it is very important to make an accurate climate investigation and use it for decision-making during the planning of the new settlement.It is very important with a good moisture protection regarding pelting rain, that is the combination of wind and rain. This is more important for buildings close to a lake, as this location normally means a higher exposure to wind.

"Det är det största beviset på kärlek, att lämna bort för att skapa ett bättre liv" : En kvalitativ studie om att vara internationellt adopterad

I meet in my work as art teacher many students of different descent, were they, or their parents, have different school experience than the Swedish. This, in combination with therecent discussion after the Muhammad caricatures about the banning of images in Islamic religion, made me curious to study what art education in a Muslim country looked like. I went to visit the Maramra Egitim Köyü school in Istanbul, Turkey, and especially their art classesfrom grade five to eight, which are the same age of students that I have been working with thelast ten years. This was my first visit to Turkey.The question I ask is: What does the practice of Turkish art education look like, using the Marmara school as an example. Which discourses can I identify in the art teacher practice? What surprised me the most was the frequent visual exposure of the founder of the Turkishstate, Kemal Atatürk.

Sexig & hatad : Modernt ledarskap, motivation, manipulation

To understand the modern leadership you have to gain a lot of experience to attain the right competence through which you are able to know what kind of leadership is most suitable to use in the current situation. Leaders agree that every kind of leadership is more or less successful depending on the situation and different organizational factors, for example the co-workers and the environment. Every leader should have a strong willpower and driving force to bring motivation to the organization and to make it more efficient. Another quality that represents a modern leader is the ability to lead and divide the co-workers and the organizations different strengths. The organizational communication is an important factor of how you, as a leader, answer to your co-workers and also how you will be received.

VIBRATIONSSKADOR - FÖREKOMST OCH FÖREBYGGANDE : Analys av ett strukturerat arbetssätt inom bostadsproduktion

Ask any constructional worker and there is a high probability that this person knows a colleague with pain or other disorders caused by working with power tools.According to the Swedish Work Environment Authority 71 percent of the Swedish constructional workers is exposed to vibrations at least 25 percent of the working hours. Despite this, the number of reported occupational sicknesses caused by vibrations is as low as 1, 4 percent.JM Ltd. is one of the largest constructional companies in Sweden. Their main business is new housing and development of residential areas. God quality and low impact on the environment is a part of great importance in the company?s long-term goals.

Wavelettransform med Morletwavelets för analys av satellitmätdata

This thesis is divided into two parts. Part one contains a general description of the flexographic printingtechnique. Part two contains a more detailed investigation in the areas substrate, inktransfer and trends, which are only briefly commented in part one, and conclusions and comments.The major problem concerning substrate is washboard. This phenomena can be limited if one can control and minimize the amount of glue applied in the single- and double facer, use high surface weight on liner, use low surfaceweight on fluting and control the humidity during the conditioning of the corrugated board. Corrugated board with a smooth surface radically increases the quality in print.
