Materialhantering och alternativa förpackningslösningar : En studie vid GETRAG All Wheel Drive AB
Köpingsföretaget GETRAG All Wheel Drive AB utvecklar, tillverkar och levererar komponenter för drivteknik till personbilsindustrin. Genom projektet 580-9 planerar företaget att införa en monteringsbana för en nyutvecklad produkt. Till denna önskar företaget skapa en materialhantering som är kostnadseffektiv, lever upp till kundernas krav på hög kvalitet samt utesluter hantering av träemballage vid monteringsbanan. Syftet med examensarbetet är därför att ge förslag till en kostnadseffektiv materialhantering där emballage som avger restprodukter inte hanteras vid monteringsbanan.För att undersöka examensarbetets frågeställningar har vi utrett hur materialförsörjningen till banan bör skötas. Studien bygger främst på teorier om lean produktion och förpackningslogistik.
Miljöbedömning av olika behandlingsmetoder för organiskt hushållsavfall, slakteriavfall och flytgödsel
Organic material used for biogas production can also undergo other treatments. The
emissions and impact from the different treatments are evaluated in this
environmental assessment, with a focus on energy and climate. The materials
included in the study are organic household waste, slaughterhouse waste and liquid
manure. Other than biogas production, the possible treatments for organic household
waste and slaughterhouse waste are incineration and composting, and for liquid
manure storing and spreading. The analysis is based on data and information from
current and relevant literature, and relates to the conditions in the Swedish energy
system.
Kvalitet och Processutveckling : -Av elektroniskt informationsutbyte (EDI)
Syftet med detta examensarbete är att undersöka möjligheterna för utökad kundnytta och kvalitetssäkra implementeringsprocessen av elektroniskt informationsutbyte (EDI). Detta uppnås med kvalitetsutveckling som grund, vilket omfattar processorientering.Rapporten inleds med en beskrivning av arbetets syfte och vilka problem som står till grund. Vidare introduceras företaget som uppdragsgivare och relevant teori tas upp, detta för att bilda en referensram inför de metoder som använts för att förbättra processen. Slutligen så presenteras resultaten och en diskussion hålls kring detta, med vidare rekommendationer för fortsatt utveckling.EDI processen har visualiserats dels med hjälp av akademiska litteraturer och dels från empiriskt material. Visualiseringen av processen har bildat en översikt av dess brister och problemområden (bland annat tidsfördelningen utmed processen och grunden till låg kvalitetsstandard), vilket har gett möjligheter till effektiva lösningsförslag för vidareutveckling.
Hållbar vattenkraft i Nissan : En förstudie och konsekvensutredning över förutsättningarna för ökade vandringsmöjligheter med nya fiskvägar.
The hydropower from Nissan River is of national interest and produces annually 230 GWh from the twelve power stations in the main flow. For modified waters a consideration between the power production and the biological values has to be made. This reports serves as a pre-study for Nissans Vattenråd. It tries to evaluate some of the biological values in the Nissan basin and map the power production in the area. And the size and value of lost power production from new fishways for the twelve stations in the main flow.The investment of new fishways is calculated using simplified templates with values from the business.
Restriktioner av växthusgasemissioner : hur påverkas lantbruksföretagens ekonomi och produktionsinriktning?
The agricultural sector accounts for about 13 percent of the total load of greenhouse gas emissions from Sweden (Swedish Environmental Protection Agency, 2007). The Swedish objective to reduce the greenhouse gas emissions with 40 percentage units to the year of 2020, based upon the year of 1990, might imply stricter regulations for Swedish farmers. A regulation or other forms of economic incentives is probably necessary to reduce the emissions originating from the agricultural sector.
This study aims to investigate the economic and managerial impact on two agricultural firms with differing production system given that a constraint on green house gas emissions is introduced. Gases included in this study are carbon dioxide, methane and nitrous oxide.
Utvecklingen av grammatikinstruktioner och övningar i svenska läromedel för spanska : En läromedelsanalys om explicit instruktion, input, produktion och interaktivitet i undervisningsmaterial för främmandespråk
This study investigates if and how grammar instructions and exercises in Spanish textbooks have evolved during the last thirty years. More specifically it focuses on how the grammar is presented (explicit instruction) and on the nature of the exercises (input, production and interaction). The method for investigating these things is firstly an analysis of the explicit instruction, and secondly a quantitative study of the exercises. The number of textbooks analyzed in this study is four and only the chapters that focus on teaching the preterite are included in the analysis. The result shows a tendency towards direct explicit instruction and controlled production practice.
Installation av la?glutande fingaller fo?r fra?mjande av ekologisk funktion i vattenkraftverk : En fallstudie av ett kraftverk i Umea?lven
The purpose of this bachelor degree thesis is to analyze technical issues associated with an implementation of a low sloping trash rack with narrow spacing. A hydropower plant in Umea?lven was used as a case study. The basis for the study was a model where trash racks were dimensioned for inclinations between 25 and 45 degrees. Corresponding head loss, durability and water speed through the rack were then determined for each inclination.
Effekten av kvävegödsling på gasproduktionen vintertid i boreala sjöar
To investigate effects of nitrogen on in-lake CO2 and CH4 production during winter, three pair of lakes was subject for a fertilizing experiment in which one lake in each pair was fertilized with nitric acid (HNO3) directly into the water column in the summer of 2012. The lakes in each pair are assumed to be morphologically, hydrologically and biologically similar, that is, the non-fertilized lakes are considered references. The pairs do differ in one major way by being progressively less humic, going from around 25 mg/l to 10 mg/l DOC. Sampling and analysis was carried out at the end of the frozen period in 2013. Results show a significantly higher concentration of both CO2 (p<0,001) and CH4 (?=0,1, p=0,053) between impact and reference sites in the two less humic pairs.
Metanpotential för alger och bioslam blandat med pappersfiber
In this thesis the methane gas potential of three different substrates, two algaes Saccharina latissima and Laminaria digitata and biosludge mixed with paper fiber was studied. This was done by batch experiments in a laboratory environment to examine the gas production and composition of the produced gas.Biogas production is a complex anaerobic digestion process in which various microorganisms decompose the substrate in steps and at the end produce biogas and a residue. Many factors affect the production of gas, for example the substrate content, temperature and pH in the digester.The analysis of methane potential were divided into two experiments. In experiment 1 substrates were digested along with inoculum from Växjö waste water treatment plant in a temperature of about 37 ?C.
Mobilt internet för skogsbruket med CDMA2000 i450 MHz - bandet :
Improved wireless datacommunication with the forest machines might be the next big step in the logging process. The use for wireless communicationsystems within the forestry is among other things to report the production from the forest machines, to supply the machine opera-tors with the right information and for safety. CDMA2000/ 450 is a third generation mobilecommunicationsystem which could replace the old NMT- 450 and for comparatively low costs. The reason for the low costs is that you only have to use the old NMT- 450 masts and supply them with new equipment. In the test of CDMA2000/450, that has taken place in northern Uppland, two kind of files have been sent.
Tidsåtgång på akutmottagningen - patienter med bröstsmärta : En kvantitativ observationsstudie
ABSTRAKT Patienter spenderar generellt lång tid på akutmottagningen, och i samband med Akademiska sjukhusets LEAN-arbete för att effektivisera akutvården så gjordes denna tidsstudie. Syftet med studien var att undersöka hur lång tid patienter med bröstsmärta spenderar på akutmottagningen, hur lång tid det tar innan de blir triagerade och hur lång tid det tar innan de träffar en läkare. Könsskillnader och huruvida patienterna ankom i ambulans eller via reception studerades. Studien var en kvantitativ observationsstudie där 48 patienter deltog, 33 kvinnor och 15 män. Medelåldern var 56 år, och ålderspannet var 21 ? 91 år.

Title Becoming involved in the planning process - from the construction workers perspective.University/Institution Halmstad UniversityKeywordsEmpowerment through participation, construction workers involvement in decision making in the planning process, knowledge management and communication in the planning process, partnering, human resource managementAimThe aim of this bachelor thesis is to provide knowledge and examine how construction workers perceive involvement in the planning process of partnering projects, what they can contribute and what they get out of the planning process.Methodology The study was conducted with a qualitative approach in the form of semi-structured interviews. The interview studie consist of 10 interviews with construction workers who are specially educated in participating in the planning process at the company ByggDialog AB.ConclusionAll respondents are positive to be involved in the planning process. The main advantages they can see is that they are able to influence technical solutions and methods that will be used later on in the production. Therefore it is important to consider when construction workers should be involved in the planning process so that they get the chance to influence in this decisions.When it comes to the decision making the construction workers should be involved in the decisions that are related to their tasks in the production such as technical solutions, choice of methods and materials. Their main duties and working hours should be in the production.Involvement in planning does not automatically mean that the construction workers are involved in the decision making, it is up to them how much they participate.
Den allvarsamma leken : Om källan till mening i arbetet
Based on 30 years of work experience in TV and film production, I have made a phenomenological analysis of my perception of meaning in work - how it arises and how it is undermined. The story starts in my experience of early professional film making in the 1980's and describes how a change to work in TV production required the development of a new professional identity. The text also illustrates how as a female director I have managed my role in a male dominated and structured work environment. Being defined as an exception from the male norm has pushed me towards femininist reflection and the need to redefine my own work role - the generally accepted view having felt uncomfortable. An analysis of structural change in TV and film production shows how market pressures and ways of thought have increasingly invaded cultural endeavour. Professional spheres of influence are weakened, while developments in the media are characterised by a commercialism which encroaches more and more upon artistic, spiritual and moral values. This attitude, where quality is in retreat, has transformedprogramme makers from creative originators into becoming suppliers of raw material in a factory- like process geared to produce great volume at low cost.The aim of this essay is to show how changes in society and in TV and film making have affected my perception of my work.
Lean-verktyget värdeflödesanalys i projektprocesser: En fallstudie vid trafikverket Region Nord
Värdeflödesanalys är ett verktyg inom managementkonceptet lean, en verksamhetsstrategi med rötterna i det japanska företaget Toyota. En värdeflödesanalys innebär kortfattat att identifiera och visualisera aktiviter som skapar värde eller innebär slöseri inom en process. Kartläggningen används sedan som utgångspunkt för att genomföra förbättringar ur ett helhetsperspektiv. Lean har sedan mitten av 1990-talet blivit allt vanligare bland organisationer i västvärlden och utvecklingen har gått från tillämpning på verkstadsgolvet till att leda även administrativ verksamhet. Synen på arbetsuppgifter såväl som projekt i form av återkommande processer gör att lean kan tillämpas inom de flesta typer av verksamheter.
Är merinokorsningar ett alternativi jämtländsk fårhållning?
Sheep breeding contributes not only with wool, hides, meat and milk but also with openlandscapes. The sheep?s wool is a good raw material thanks to a lot of different qualities as itis water rejecting and easy to form. The wool production today is concentrated to specificplaces in the world which leads to environmental problems and a distorted market. InJämtland, a province in Sweden, there is right now a staking going on for local production andrefining of wool in a project called Ullforum.
