Förädling av textil- En studie om att skapa mervärde av skänkta kläder och textilier

Våren 2011 beslutade Röda Korset i Sverige att sluta skicka skänkta kläder som bistånd till katastrofområden. Röda Korset ställdes nu inför frågan vad de ska göra med de skänkta klä-derna för att omvandla dem till en resurs.Uppdraget var att i samarbete med Zäntrumprojektet och Röda Korsets secondhandbutik Ku-pan förädla de skänkta kläderna på ett miljövänligt sätt. Tanken är att Zäntrumprojektet ska sy om de skänkta kläderna till nya produkter som sedan ska säljas i secondhandbutiken Kupan.Syftet med den här uppsatsen är att finna ett sätt att förädla de skänkta kläderna och skapa nya produkter av dem. Vidare ska de skänkta kläderna skapa bättre resurser till Röda Korset som de kan tillgodogöra sig i sitt välgörenhetsarbete. Produkterna ska vara skapade på ett sådant sätt att de avger minsta möjliga avfallsmängd, främjar hållbar utveckling samt är attraktiva för Röda Korsets secondhandbutiks kunder.

Re: Yarning

From a social perspective, I have been working on how to change current consumption patterns through a change in people's behavior and attitude towards their possessions. The concept is based on how we can value, care for, and preserve our belongings by using theories in the empathic design field. I have created a structure that allows people to become an active part of a creative process and create their own products. Through this commitment, an emotional relationship is built between the user and the product, and the product tends to gain a longer life. Based on a method to manufacture your own yarn by reusing old clothes, I want to provide the basic tools for an easy and playful way to build the knowledge needed to produce something useful..

Tillämpningar i kemiundervisningen : en studie av strategier för att presentera och synliggöra tillämpningar

The aim of this study is to investigate how and in which form students come in contact with practical applications in the upper secondary school course Chemistry B. The study is based upon the assumption that all learning is situated in a social environment. The theoretical framework is the design theory perspective, which entails an assumption that the pedagogical tools affect the knowledge content.The empiric materials in the study are collected through three methods: textbook analysis, classroom observations and questionnaires. Two groups of students and their teachers were observed during a section of the relevant course. The textbook analysis focuses upon the same course section in the textbooks of the two groups and compares these books with the relevant section in a third textbook.

Historiska emissioner av bly och arsenik till luft från Åfors Glasbruk och deras konsekvenser för miljön.

Åfors glasswork was a company which started in 1876 and closed in 2012 due to the bad economical situation in the company. After its closure, the glasswork left behind contaminated soil with different concentrations of heavy metals such as, arsenic from arsenic trioxide, a chemical used to remove bubbles during the melting of glass, and lead oxide, a chemical used in the production of crystal glass. Crystal glass?s production occurred under 1921-1971, but emissions of lead into the air from Åfors glasswork continued until 2011, because of the artist Bertil Valliens? artglas was made in Åfors glasswork from 1970?s and onwards.The aim of this study was to estimate how much lead (Pb) and arsenic (As) that were released by Åfors Glasswork into the atmosphere during the operational period of the glasswork in comparison with how much of lead and arsenic were purchased for the company. Added to the assistance of the data from National Archives the variations in the activities of Åfors glasswork could be shown.

Demand and perception of fertilizer : among small-holder farmers in Kenya

Hunger is a problem in some parts of the world (www, FAO 1, 2012). The lack of food is often a result of insufficient knowledge in soil fertility management (Röing de Nowina, 2012). Ongoing hunger and malnourishment are quite prevalent in Sub-Saharan Africa and are often combined with poverty (www, FAO 1, 2012). Farming is the most common occupation in this area and the farms are often small-scale farms with subsistence crops and a few cattle. The farmers who operate these small-scale farms are economically a weak group.

Hur ska klädexponeringen se ut i den perfekta webbshoppen?

I dagens samhälle handlar det om att vara så effektiv som möjligt för att vinna tid. Som Benjamin Franklin en gång sa att ?Tid är pengar?, är något som vi människor allt mer tagit fasta på då vi ställer höga krav på utvecklingen och dess teniska förmågor. Idag har de flesta människor tillgång till en dator med internetuppkoppling som vi dagligen utför sysslor vid. Det kan vara allt ifrån jobbrelaterade aktiviteter, hålla kontakten med nära och kära, söka information om vad som händer i världen och i vår omgivning, till mer nöjesinriktade delar såsom online spel och shopping.

Konsumentprisindex för kläder och skor 1986-2005 - Dekomponering och prognostisering

The essay initially intends to find adequate models to describe and forecast monthly data for the Swedish Consumer Price Index sub group Clothes and Shoes 1986-2005. The time series observations during 2006 are considered ?out of sample period? which is used to evaluate the forecasts. The purpose is to perform time series decomposition and to investigate and analyzethe seasonal pattern. The Box-Jenkins approach is used to find adequate ARIMA models.

Vad är ett riktigt slut? : en kritisk granskning av genrepedagogiken i arbetet med sagogenren

With this paper the aim is to find out whether there are any differences in how five students from the north part of Africa structures their tales in comparison with the Nordic tale "The emperor?s new clothes". The purpose is to look at how the genre pedagogy can be said to relate to these differences. What happens to the "deviant" structures?Based on literature and research on the subject, I have concluded that there are certain patterns of how a tale "should" be structured based on Western standards.

Lagafors CPU : Chemical Production Unit

This dissertation is performed at the request of Lagafors AB who develops and manufactures stationery and mobile hygiene solutions for companies in the food- processing industry. The objective of this dissertation is to develop and construct a new, cost efficient cleaning station based on an innovative technology.The technique is based on serially connected dosing pumps which allow the customer to work with concentrated detergents. This leads to serious reduction in the clients use expenses. Two units have been developed with this technique, one that is stationary and one that is mobile.The dissertation has led to good results which resulted in the sale of the first stationary unit of the Lagafors CPU before the end of this dissertation. .

Simulering av COD-fraktioner i en aktivslamanläggning vid en sulfatmassafabrik

This thesis work was made for Södra Cell Mörrums bruk in Blekinge. The purpose of the work was to develop a computer model in the simulation program Extend for the removal and balance of organic oxygen consuming substances, measured as COD (Chemical Oxygen Demand), in the new biological treatment plant in the mill. The plant produces two different pulp products, TCF- (Totally Chlorine Free) pulp and ECF- (Elementary Chlorine Free) pulp, for sale. The different bleaching procedures affect the characteristic of the wastewater and thus the effectiveness of the biological treatment plant.In the model that was developed the COD in the wastewater was divided into five different COD-fractions: soluble easily degradable (SS), soluble hardly degradable (SR), soluble inert (SI), particulate inert (XI) and particulate biomass (XB). To create the model FlowMac? was used as a base.

Hommage till slit och släp - västerbottniska arbetarskjortor i en undersökning om mönsters påverkan på kläder

Hommage till slit och släp is a tribute and a resarchabout patterns relation to clothes. The primary goalof the project was to examine how a pattern couldchange the apperance of a garment and how thegarment?s construction and material would impactthe pattern. The formative survey was about thesparsely populated areas in the north of Sweden andhow theese areas have been treated by the swedishgovernment. The issue worked as an inspiration andmethod which I used in the patternresearch.

Patologiska förändringar och säsongsmässiga variationer i testiklar från svenska brunbjörnar (Ursus arctos) :

Functioning reproductive organs are essential for the survival of a species. The reproductive system is very sensitive to exposure of chemical substances of anthropogenic origin. Humans release great amounts of chemical substances to the environment by our means of life and these substances have been proved to have a negative effect on the reproductive ability of different vertebral classes. In the polar bear (Ursus maritimus) a declined reproductive ability as an effect of decreased testosterone levels and decreased testicular size has been connected to the presence of high levels of organohalogenic compounds like PCBs. Although the Swedish brown bear (Ursus arctos) is not as carnivorous as its close relative the polar bear it is still exposed to environmental.

Utveckling av en HBV/PULS-model med sammanfogade markfuktighets- och responsrutiner

Soil properties affect the chemical composition of soil water. When studying transport of chemical substances through a basin, it is therefore important to know from which soil layer the main part of the runoff is generated. The aim of this study is to develop an HBV/PULSE model with merged soil moisture and response routines, which generates good approximations of groundwater levels. It should be possible to extend the model to simulate transport of substances and take into account which soil layer the groundwater level is currently in. The hydrological version of HBV/PULSE is used since there is no need to account for pH or alcalinity at this stage.

Genus i barnboken : En undersökning om hur flickor och pojkar skildras i barnböcker

The purpose of this research is to analyze six children?s books from a gender perspective and thereby investigate in what way boys and girls respectively are portrayed in books.My general question is:How are boys and girls portrayed in children?s books?This question has been broken down into four minor questions:What type of clothes are the people wearing? Are people predominantly male or female? Have people specific attributes which are linked to their sex? Are people performing specific actions which are linked to their sex?In my research I have combined quantitative and qualitative methods and my theoretical framework has been gender.This study reveals a change in children's books with respect to how the different genders are portrayed. The progression is towards a more equal portrayal but despite this, patterns typical for the respective genders shine through..

Rotningsstimulerande effekt och kemisk analys av vattenbaserad extraktion av vedartade och örtartade skott av Salix smithiana Willd. :

Cuttings of Lonicera xylosteum L. were treated with willow extract to study the response in rooting capacity. The extracts were prepared by mixing chopped pieces of Salix x smithiana Willd. with water in a warring blender. The investigation comprised 2 types of salix extracts based on differences and dynamics between twigs in winter dormancy and twigs with new shoots. To explore the rooting response, three tests were made.
