Kartläggning av kapacitetsutnyttjandet och ställtider på Stålöv AB : Survey of the use of capacity and set up times at Stålöv AB
The aim of this report is to analyse the use of the capacity at the CNC (computer numerical control) cutters and show how the level of set up time for these cutters at Stålöv AB. This assignment is concrete whereas there are no subjective questions to this matter and there are only cold figures presented.Production economy is getting more important as the competition hardens and there are several different ways to increase productivity and efficiency in a company. In order to increase productivity and efficiency work studies are used to, through an analysis, find developments in methods that result in improved work methods and to establish the time that are used. Increased production of different parts and customer driven production in combination with increased demands on rationalisation of capital have led to an enlarged interest for shorter set up times in the production.To point out the use of capacity and the set up time of the cutters at Stålöv AB we used frequency studies. Frequency studies are work measure methods based on random observations on predetermined events to calculate the relative occurrence of these events.
Klimatförändringarna i nyhetsdiskursen : En kritisk diskursanalys av klimatrapporteringen i Dagens Nyheter och New York Times
Titel: Klimatförändringarna i nyhetsdiskursen Antal sidor: 47 Författare: Emelie Sahlström & Sofia Öström Handledare: Ulrika Olausson Kurs: Medie- och kommunikationsvetenskap CPeriod: HT 2010Universitet: Avdelningen för Medie- och kommunikationsvetenskap, Institutionen för humaniora, utbildning och samhällsvetenskap, Örebro universitetSyfte: Syftet med denna uppsats är att undersöka om och i så fall hur klimatförändringarna i nyhetsdiskursen i New York Times och Dagens Nyheter har likheter, respektive skiljer sig åt. Vi undersöker också om klimatrapporteringarna är uppbyggda genom nationella eller globala identitet, om något ansvar utkrävs samt vilka som tillskrivs detta ansvar och om det finns en vetenskaplig säkerhet eller osäkerhet gentemot klimatförändringarna. Utifrån dessa har vi i slutdiskussionen diskuterat hur resultaten kan kopplas till USA:s och Sveriges klimatpolitik.Teorier: Teorierna är relaterad och presenteras i relation till tidigare forskning. De teorier som används i denna uppsats är, ansvarsutkrävande, vetenskaplig säkerhet och osäkerhet samt identitet. Metod och material: För att uppfylla syftet använde vi en kritisk diskursanalys samt mikro- och makronivåerna. Vi har analyserat 8 artiklar från New York Times och 9 artiklar från Dagens Nyheter.Resultat: Resultaten visar att DN och NYT, som Europa och USA står mot varandra i klimathanteringen.
Närproducerat : Attityder och definitioner bland Uppsalastudenter
From an environmental and climate perspective we are becoming more and more aware of what we eat. Consumers want to know how their food is produced and where it is coming from. A term commonly used in this discussion is local produce. At this time, there is no clear definition of the term and a wide range of definitions can be found. However, despite this lack of definition, the term is often being used by producers, traders and consumers..

AbstractOur world is facing new challenges depending on the climate changes. The UN panel of climate changes has determined that the human race is responsible for the changes, but also that we have the opportunity to reduce the effects. This demands that the information reaches out to the public which means that the school system carries major responsibility to this type of questions. This also means that the teachers have to be observant, and give the questions the attention which is needed. The purpose of this essay is to see if this awareness exists today among active teachers and teacher students and if the perspective differs among them, but also their opinions is in agreement with the course plan in the subject.
Klimatkabinett : Komponenter och konstruktion
This report describes the construction of a climate-cabinet for testing of HV-cards (High Voltage) produced at VG Scienta. The main part of the report describes all the different components of the cabinet. The most important parts are a PID regulator from Eurotherm model 2408, a solid state contactor (SSC), a thermocouple, a finned resistor from DBK and different fans. The report even includes the connection between components by cable wiring, isolation, grounding, fuses and shaping of metal goods.As the cabinet also communicates with a computer, the report includes the solution of the data communication using the software iTools from Eurotherm. The communication part includes information about a converter that converts EIA422 to USB.The cabinet was produced at a company, called VG Scienta, in Uppsala during the spring 2010.
Värvningsförbud av anställda och konkurrensbegränsande samarbeten
This thesis focuses on employers? use of non-?solicitation of employees in commercial contracts within the union?s internal market and how this can result in restrictive practices in violation of European law. Using legal method, legal economic considerations, and guidance from modern American legal development in antitrust law, this thesis is aiming to investigate how this kind of anticompetitive cooperation in the European labor market should be assessed. The result seems to be that despite a distinct and pronounced restrictive approach to the application of EU competition rules in the labor market, there are strong incentives and not any legal impediment to apply Article 101 TFEU on no cold call agreements between employers. .
Det moderna risksamhället: En studie om klimatrisker inom kommunal krisberedskap
Klimatförändringarna är numera ett fenomen vi inte kan bortse ifrån. De sker här och nu och det råder mer eller mindre gemensam vetenskaplig konsensus om att så är fallet. Med klimatförändringarna kommer risker vi i nuläget har väldigt svårt att förutse och förhålla oss till och därmed påverkas integrationen av dessa i den kommunala krisberedskapen. Syftet med studien är att undersöka vilka faktorer det är som påverkar integrationen av klimatrisker inom den kommunala krisberedskapen. Resultatet är baserat på ett antal intervjuer som har genomförts med personer inom kommun och kommunfullmäktige.
Flygets framtid : Från problem till möjligheter
The purpose of this essay is to investigate the airline industry and its part in the mobile community. Further on, to investigate the factors that throughout history are having an impact on the airline industry and have lead to the condition of today. Through this information we are outlining the future of the airline industry.This essay has been written in a qualitative approach. The empirical gathering has been made through interviews based on open discussions between the interviewers and respondents. We started out with creating a theoretical pre-understanding and continued by comparing how well these theories matched the reality.The gathering of the theoretical material was chosen on the basis how well it matches the subject of our essay.
Ekosocial välfärd : En kunskapsöversikt
There seems to be a consensus in the world that the climate is changing, bringing unpredictable and severe consequences for both humans and nature. The feld of social work is known for helping misfortunate individuals and groups, and is said to deal with people in their environments. Yet there seems to be a lack of giving these environments meaning as also something natural. This thesis has the purpose of exploring the connection between social work and the physical environment made by research literature, using the methodology of literature review. The questions asked is in which ways the physical environment can be connected to human welfare; if so, what implications are there for the feld of social work, and fnally how can the discussion be understood using a typology over environmental sustainability presented by Andrew Dobson.
Skuggvävens effekt på fryslagrade täckrotsplantor av tall (Pinus sylvestris) i upptiningsstadiet :
This project was an assignment by Sveaskog and Svenska Skogsplantor. The purpose was to study the effect of protective fabric on the thawing stage of frozen pine seedlings. The function of the protective fabric is that it should protect the seedlings against strong sunlight and create an even temperature inside the boxes containing the seedlings. The result has shown that there was no statistically significant difference when the protective fabric was used or when it was not used, although this was probably due to the weather conditions. The study was carried out under cold and cloudy weather conditions and probably would have given other results if there had been more sunny days with a higher ambient temperature.
Lagring av kyla med horisontella markvärmeväxlare för kylning av koncepthus i Mellanöstern
Norconsult AB has developed a solarhousing concept, a house designed for the warm climate in the Middle East andwith large quantities of solar panels installed. The cooling system for the house was designed in an earlier report, the purpose of this thesis is to investigate the possibility of short and long term storage of thermal energy via an underground energy storage volume.Two different designs of the storage and three different filling materials have been integrated into a model to simulate different cases. The first design consisted of pipes installed in the ground, without insulation. The second design consisted of an insulated concrete box installed to prevent thermal energy from the surrounding soil to flow towards the lower temperature regions within the storage. The three different filling materials were dry saudi sand, water saturated saudi sand and the filling material used by the client for energy storage in Sweden.The results from the simulations show that neither of the designs, regardless of the filling material, managed to extract enough thermal energy from the house to the ground to uphold the demands of indoor climate.
Energisäkerheten för fjärrvärmeanläggningars bränsletillförsel i Mälardalsområdet
There are several energy systems in the Swedish society and to ensure the comfort and health of the citizens it is of importance that the different energy systems are functioning properly. District heating is one of these energy systems and many household depend only on district heating to warm up their homes.
District heating is dependent on several processes where every step needs to function in order to deliver the produced heat to the end consumer. Previous studies have investigated the distribution of district heating and how to make customers choose district heating as their heating method. The supply of fuel to the district heating plant has not been studied as much, even though it is an important part of the whole system. This thesis is a part of the project NORD-STAR (Nordic Strategic Adaption
Research), which has focused on climate adaption in the Nordic countries.
Frigörelse av fosfor från färskt, fryst och torkat växtmaterial : ett laboratorieförsök för att öka förståelsen för fosfordynamiken inom växtodlingen
Phosphorus is the single most potent contributor to eutrophication of freshwater and has also been shown to contribute to the toxic algae blooms in the Baltic sea. The
dynamics and paths of losses of phosphorus from arable lands are not fully understood.
It is known that phosphorus can be lost directly from plant material to water.
In studies where plant material has been subjected to several freeze-thaw cycles, large amounts of phosphorus have been lost. Most studies have been conducted
under field conditions, with many factors effecting the measured losses of phosphorus, such as weather and type of soil. This study was performed in a controlled environment without the presence of soil. Instead of soil, small glass beads were mixed with the plant materials in vessels, to make possible homogeneous leaching with water through the mixture of glass beads and plant materials.
In this study, clover, ryegrass and dry straw were cut to pieces, approximately 2 cm long.
Galoppträning och körning med två travare
The aim of this study was to evaluate whether gallop training, rather than regular drive training, is worthwhile for trotters race performance. Another aim of the study was to expand the author?s riding- and driving capacity, and get more practical experience on the impact of interval training on trotters. The sample population in the study was two trotters, one Standardbred, and one cold-blood. Given the small sample population, the results of the study is only indicative on the effects of gallop training on trotters, and not conclusive.
Varför är Bivarödsånsvatten så brunt?
The river Bivaröd is one of the river Helgeån tributaries which has the highest and the fastest increase in water colour. The reason behind this increase is unclear but several factors have been suggested to affect this pattern. In this work, I studied the role of land use, iron and precipitation for water colour increase in river Bivaröd for the period 1976 -2011. Data from a field study along with data from SRK for river Helgeån were used for the analyses. The results showed that both water colour and iron concentration increase and that there is a strong correlation between these two variables.
