Samordnad varudistribution i Växjö kommun : En studie om returflödet av SRS-backar
Växjö kommuns mål är att minska sin miljöpåverkan från fossila bränslen och ett steg i detta är den samordnade varudistributionen. Rapportens fokus är inriktat på returhanteringen av SRS-backar som ingår i den samordnade varudistributionen. Rapporten redogör för hur processen för returhanteringen av SRS-backar ser ut vid en samordnad varudistribution i Växjö kommun. Underlag för en processkartläggning insamlades genom semi-strukturerade intervjuer och kartläggningen genomfördes i analysen. I en samordnad varudistribution där flera olika aktörer ingår och vill få sin röster hörda uppstår det problem. Rapporten ämnar utöver att beskriva processens utseende, även att redogöra för dessa problem. Problemen som upplevs i nuläget för respektive aktör är säkerhetsrisker på grund av kvarlämnade SRS-backar på de kommunala enheternas lastkajar enligt logistikhandläggaren vid Växjö kommun, extra transport samt lagerhållningskostnader för Växjö Partiaffär, identifikationssvårigheter för Scandinavian Supply Chain.
Behovsstudie av ett energibutikskoncept för energiförsörjning utanför elnät : ? En småskalig fältstudie i Namibia
The amount of electricity is limited in Namibia and the large distance between towns andvillages complicates the energy supply in the country. Therefore an alternative way to provideaccess to appropriate energy technologies is needed. The Government of the Republic ofNamibia (GRN) has adopted an approach of helping off-grid households by establishing EnergyShops in each region in Namibia and these shops are going to sell basic renewable energy andenergy efficient products. The Renewable Energy Efficiency Institute in Namibia (REEEI), theinitiator of this thesis, is coordinating the establishment of these Energy Shops.The main purpose of this thesis was to examine the needs of energy products for the Namibianpopulation and develop an assessment method for the Energy Shop in how to select appropriateenergy products already on the world market. The purpose was also to develop a method forchoosing an Energy Shop.
Urea som kvävekälla till växande ungnöt
The purpose of this study was to examine whether urea could be an option as a nitrogen source for young cattle, the study was limited to risks related to feeding, growth and feed efficiency. Microbes in ruminants have the ability to convert nitrogen to protein, this has been highlighted by beef producers as they are in search of cheap protein feed resources. Urea can be a worthy source of nitrogen for growing young animals, because of its high nitrogen content and the low price. Studies have shown that the replacement of a portion of the total protein content by urea in diets with low content of crude protein, like corn silage, may improve animal growth and feed efficiency. Replacement of all the true protein with urea can result in reduced feed intake and microbial growth.
Vidareutveckling av PV/T-receiver för koncentrerat solljus
The rising demand for electricity and heat raises a big challange for the society and engineers. Many products have been introduced to the market to supply more energy to the energy systems. Absolicon AB is a Swedish company that develops and markets a combined heat and power generating product. The product, Absolicon X10, uses a parabolic trough to concentrate the radiation of the sun onto a receiver. The receiveris equipped with mono crystalline solar cells and is cooled by a circulating liquid media.
Konstruktion av instrument för dragprov på nervceller
This report describes how the system may be exposed to oscillations and how this can lead to resonance. Resonance is a phenomenon that occurs when a system is affected by external periodic oscillations with frequencies close to the system's natural frequencies. Structures subjected to resonance can risk great damage and destruction, why resonance is something that is important to take into account when designing structures. Alternative ways to counteract resonance is to supply damping in the system. Damping means that the resonance decreases instead of letting the amplitude increase.The report discusses some examples on constructions that have experienced the effect of resonance.
Konstsamlares agerande
Until recently, the art market has expanded for several consecutive years. The primary art market is characterized by an unclear pricing mechanism and an infinite as well as limited supply. Previous business studies have so far primarily focused either on art as an investment or on the gallery?s activities. This thesis takes an explorative approach and aims to shed a light on the art collector?s behavior on the Swedish market for contemporary art.
Trädetaljer i exteriör arkitektur : En rapport om hur arkitekturen kan tillåtas framhäva trä som byggnadsmaterial i utvalda exteriöra detaljer för ett äldreboende med massiv trästomme
Arkitektfirman Kolman X Boye Architects har fått uppdraget att upprätta bygglovshandlingar för ett äldreboende. Det är ännu ej bestämt i detalj hur byggnaden skall uppföras men beställaren önskar att byggnaden uppförs i träbyggnadsteknik. Äldreboendet projekteras för 54 stycken lägenheter fördelat på sex stycken våningsplan och en total bruttoarea på strax under 6000m2. Ingen lika hög träbyggnad med denna verksamhetsklass avseende brand har tidigare uppförts i Sverige.Vår uppgift och utmaning i detta arbete har varit att reda ut problematiken kring projekteringen av exteriöra detaljer för höga hus i trä. Utifrån kända problem avseende brand, akustik och fukt har sedan ett antal detaljer som påverkar det estetiska uttrycket projekterats.
"En gång till!" : en kommunikationsetnografisk studie om andraspråksinlärares deltagande i förskolan
The aim of the thesis was to better understand how second language learners becomes lingual participants in a Swedish preschool. Using the following research questions: In what situations are SLLs lingual participants at the preschool? What does their emerging language look like? Are the participation any different considering children's time in the new L2 context? What kind of support does SLLs receive at the preschool?Two focal children at the same preschool was studied with ethnography of communication as method. The focal children chosen were one girl (Mandarin L1, 4.0 yrs) who arrived to Sweden and started the preschool two months ago at the time of the study, the other a boy (Serbian L1, 3.9 yrs) who started preschool and learning the L2 one year and two months before the study. Situations where the focal children interacted with other children or adults were analyzed. Results showed that the focal children in interaction with each other understands some of the others intentions before being able to speak about them in the L2.
Bruka utan att förbruka - när andra intressen än ekonomin får styra
To have a forest area close to the city is of great importance for the city population?s well being. Children develop their motor skills, concentration and imagina-tion and the adults have a place to shake of the stress from work. Forest areas are used to exercise at, play in and to find a moment of peace and silence.
The urban forest and the old farming pastures at Markussonvallen and Per-Isakssonvallen already has natural assets worth to preserve and a great potential to create more. The goal is to develop a forest with a variation of tree species and ground vegetation that will appeal to the human senses and different animal species such as birds, insects etc.
Östeuropa som Den andre? En teorireflekterande uppsats med diskursanalys av intervjuer med svenska och tjeckiska UD-tjänstemän
In classic academic social studies of East Europe, terms as Communism and Post-Communism are commonly used to describe the main characteristics of this geographically imagined area. This paper makes a not so frequently seen attempt to apply Post Colonial Theory for the same field. With start point in Post Colonial theoretical writers, the author wants to find a East European Post Colonial version for the internal Europe which will supply tools for a discourse analysis of the European mind map divided into West and East. The material consists of interviews with three Swedish and three Czech officials, all working with European politics in their country's Ministry of Foreign Affairs. The analysis is carried out with inspiration of Ernesto Laclaus and Chantal Mouffes Discourse theory.
Emissioner i slutna utrymmen Med speciell inriktning på emissioner av formaldehyd och organiska syror
This study aimed to evaluate the levels of formaldehyde and organic acids that can build up within enclosed spaces. Another goal was to compare two types of paints that can be used as coating barriers within showcases and in turn compare them to the modern, and by many highly recommended, material of Marveseal®. A low volatile waterborne alkyd/acrylate paint and a two component polyurethane paint was compared to Marveseal® in two series of experiments. One series measured the level of formaldehyde, and thus the effectiveness of the three chosen barriers, and the other series measured the level of volatile organic acids, both the acids emitted from the paint itself, and that of the wood. One box in each series were not treated at all and was used as a reference.The fact that different types of materials emit volatile organic compounds have long been known.
Träplastkompositer ? ett material för framtiden? : en kvalitativ studie om marknadens önskemål för att göra träplastkompositer till ett mer attraktivt material för framtiden
Minskad efterfrågan på traditionella produkter från skogsindustrin kombinerat med ökad efterfrågan på icke-fossila material medför att företag inom skogsbranschen alltmer intresserar sig för nya produktsegment. Holmen New Business Development, en forsknings- och utvecklingsavdelning inom företaget Holmen arbetar med att utveckla produkter där trä kan ersätta traditionella alternativ. En möjlig produkt för avdelningen är Wood Plastic Composite (WPC), ett material som består av en kombination av en plastmatris och ett träbaserat fyllnadsmaterial som kan ges olika egenskaper vilka skiljer sig från rena trä- och plastmaterial.
Syftet med denna studie var att undersöka hur designers och produktutvecklare inom olika svenska branscher ser på användandet och utvecklingen av WPC inom sina produktområden, både idag och i framtiden. För att undersöka detta har 18 kvalitativa intervjuer genomförts med företag inom möbel-, köks-, fönster-, dörr-, staket- och trallindustrin.
Studien visar att ett lågt pris, hög beständighet mot till exempel röta, fukt och mögel samt att materialet går att bearbeta på samma sätt som trä är de mest önskvärda attributen hos framtida WPC-material. Miljövänlighet hos produkten är ett attribut som respondenterna tror kommer få större betydelse i framtiden men som kunderna inte är beredda att betala för idag.

The purpose of this degree project is to give an overview of the planning system of four Swedish forest companies. The involved companies are ATA TIMBER, SYDVED, BERGS SKOG and VIDA SKOG. The study is based on information from a literature study and by interviews with personals from the four companies.
Each company is described to get a better insight of the companies work and what potential they have. The description of the planning process comes after that. The companies are described separate from each other and will be compared later in this essay.
Analys av faktorer som påverkar interna leveransledtider : Dimensionering av lager
It is becoming increasingly important for companies to meet customer demands due to intense competition in today's global market, that forcing companies to improve their offerings and become better at managing their supply chain (Shen et al., 2006). Long lead times can be reduced by using different methods and strategies shows various researches. Lead times occur in the planning, production, inventories and handling of products (Treville et al., 2003).The aim of the study is to develop a method to analyze the factors that affect the length of internal delivery lead time in manufacturing companies. The method also included suggestions for reducing delivery lead-time to internal customers.The main factors that influenced the length of the on delivery lead times has summarized to make a selection among the factors that can have the most significant impact. The selected elements will be used as a method to analyze how these areas affect a company?s length on internal delivery lead times.The study shows that the causes of the long delivery lead times was the location of the customer order point, uncertain forecasts, long material and production planning time, and long waits in the production and storage.The delivery lead time, according to this report?s suggested improvements reduced by centralizing CODP and makes more reliable forecasts.
