Transportkvalitetshöjande åtgärder : en fallstudie vid GP-Last

This thesis has been done on a haulage contractor company named GP-Last (AB Gustav Perssons Åkeri) and the purpose with the paper was to analyse their traffic from Malmö to Stockholm and leave suggestions on efforts that GP-Last can use to increase their level of transportation quality. This has been done with two main questions, which problem do they have today and which efforts they need to do to solve their problems? Through a case study with interviews as method to collect data it showed that GP-Last had four main problems.        Not enough information about their freights. The transport planning unit in Malmö doesn?t have the exact delivery address when GP-Last begins to bring in the gods.        There are no clear routes.

Nanostrukturell ytbeläggning på utsatta delar av marina drivlinor

Nowadays naval units are participating in international missions, where new and in many cases tougher conditions will affect their propulsion. This essay deals with some of the now developed nanostructure coatings and gives a presentation of how the coatings could function on some exposed parts of the naval powertrain. The essay investigates the possibility that the coatings can be used as a protective layer that will reduce or prevent wear on selected parts of the naval powertrains. As a basis for the essay, nanotechnology is described, as well as different reasons that wear occurs and application techniques for coatings The conclusion is that nanostructured coatings can be applied and provide a much better result on hardness and wear resistance as of naval powertrains compared to micro-structural coatings, both for manufacturing and renovation. The essay presents a few examples of the military utility of the nanostructure coatings as well as suggestions for further research..

Geografiska informationssystem för studier av polyaromatiska kolväten (PAH) : undersökning av djupvariation i BO01-området, Västra hamnen, Malmö, samt utveckling av en matematisk formel för beräkning av PAH-koncentrationer från ett kontinuerligt utsläpp

At the end of August 1999, the local government council of Malmö city decided thatthe area known as Kvarteret Bilen would be made available for the European HousingExhibition 2001 (Bo01-mässan). Kvarteret Bilen extends over approximately 80hectars and includes the western parts of the Western Harbour area (Västra hamnen)of Malmö.Kvarteret Bilen as a whole, but especially the western sections of this area, the socalledBo01 section, has been the subject of heated discussions. This is mainly due tothe fact that the ground in question has proven to be contaminated to a certain extentby different chemical compounds. Investigations undertaken during 1998 showed sporadically high concentrations forespecially one chemical group: polycyclic aromatic hydrocarbons (PAH).The first part of the paper describes the use of a mathematical equation (Fetter 1994)to calculate the concentration of PAH from a continuous discharge at a given time byemploying Geographical Information System (GIS). Even the constraints of theequation are discussed, as well as the consequences that follow as a result of usingGIS.The second part of the paper focuses on the connections between the content ofcarcinogenic PAH in Kvarteret Bilen and the ground water level and type of fillingmaterial.

Habitus - ett arbete om klass

 Why is it that we still live in a society where an individual's social background plays such a big part in their chances of reaching a higher education? Despite the numerous educational policy reforms, especially in Sweden, it still seems that an individual's career choices are pretty much related to what kind of social class they grew up in. Sociologist Pierre Bourdieu claimed that social class is reproduced in the school system, and that students from the lower classes are much less likely to reach a further education than students from the middle or upper classes due to injustice in the school system. One thing that plays a big part in this "Catch-22" situation is the concept that Bourdieu calls habitus. Habitus could be explained as an individual's taste, knowledge, ability to master the spoken language, etc. Your habitus is manifested in the choices you make, the music you listen to, how you dress and the way you speak, and it determines your relation to the education system and life in general. As part of my essay, I wanted to interview students from lower or working class at my school, Konstfack, to see if they have had any negative or positive experiences from their encounter with a higher education. And if so, could they be linked directly to their social background? As a reaction to my own and my interviewees? experiences and frustration, I use the concept of habitus in my practical work.

Sin egen lyckas smed... :en kvalitativ studie om socialarbetares drivkraft för att stanna kvar i yrket

The purpose of our paper was to understand the motivators that kept the social workers within the profession. Social workers' have a profession that, to the greatest extent, means high working load and difficult problematic issues. On the basis of this starting point we asked us why so many social workers still choose to remain within the profession for several years. The purpose of our paper is to understand what motivates the social workers to stay within their profession. To understand which are the motivators, we decided to use the theory salutogeent perspective with Aaron Antonvsky's sense of coherence.

Beteenderesponser hos farmuppfödda minkar (Mustela vison) hållna i stora och berikade burar :

The standard housing of farmed mink provides little opportunities for them to behave naturally and abnormal behaviours such as stereotypic behaviour and tail biting may occur. To prevent abnormal behaviours animals in captivity are often provided with different kinds of enrichments. The aim of this study was to investigate what kind of enrichment farmed mink use when they have several kinds to choose from and to observe if abnormal behaviours can be decreased with a larger cage and a more multifaceted environment. Totally 20 silver blue, 10 months old female mink were kept in traditional cages (80x30x40 cm) for 7 days and in larger cages (195x80x40 cm) with several types of enrichments for 7 days. The enrichments were wire net- and wooden shelves, wire net- and plastic cylinders, water bath, plastic ropes, branches, straw and tennis balls. One-zero scan sampling on behaviour and choice of place were performed during 3 hours and 20 minutes prior to feeding during 7 days per treatment in April 2004.

Beckholmen : Varv & Marina

A new shipyard on the island of Beckholmen consisting of a new ship hall and complementary workshops. The program is extended with rentable industrial space for other smaller companies to take advantage of synergies with the yard and to create an active maritime cluster around Beckholmen. By building a marina and a port at the northern shoreline of the island the shipyard can expand their potential customers to non-commercial and larger recreational boats that are becoming increasingly common in Skärgården. The port is also supplemented with a combined naval fuel station, harbor office and a small café. The boat traffic in the region gets a additional stop at the end of the port and act as an additional gateway to Djurgården. Several small retail spaces with direct access to the water is created along the promenade between the port and Djurgården. The shipyard gets a modern and efficient industry building, while the island is made available to the public again, and Beckholmen will hopefully take an equal place in the city's consciousness as it does visually in the inlet to Stockholm..

HUR KAN VI REDUCERA DEN INTERNA ÖVERGÖDNINGEN SAMT REGLERA ALGBLOMNINGAR FRÅN ATT NÅ EGENTLIGAÖSTERSJÖNS KUSTZON ?? : En vision om att återfå en balans i Östersjön genom att skörda algöverskott och använda biomassan som en framtida råvara.

The Baltic Sea is one of the world?s most polluted seas. Increased discharge of nutrients due to greater populations of people, together with a slow water exchange, creates great stress on the sea. Too much nutrients leads to increased growth of algae and causes problem in the ecosystem. Even if we reduce nutrient discharge the problem still exist in the ocean. When algae dies and sinks, more nutritional substances is produced called "internal eutrophication". This phenomenon will grow in the future due to a warmer climate and the problem is spreading towards the coastal zone, which is an important site for fish recreation. By removing the abundance of algae, the nutritional and toxic substances are reduced and the algae biomass can be a future resource for biofuel production..

Täckning av plansilo :

With the increasing costs in concentrate the importance in producing ensilage with a high quality is becoming more and more important. To succeed with this goal it is of importance not only to harvest in the right period, but also to be able to store the ensilage without a decrease in quality and nutrional values. To maintain a good ensilage the covering of the ensilage must be carefully made. An unsuccessful covering causes mould to grow in the ensilage, which both increases the work load and also increases the amount of feed which is wasted. A bigger amount of spoiled feed also increases the risk of feeding spoiled feed to the cattle.

Produktionseffekter och behov av dikesrensning i Sveaskogs skogar :

Ökad efterfrågan på virke har lett till ett ökat intresse för och användande av olika produktionshöjande åtgärder. En sådan åtgärd är dikesrensning som innebär att befintliga diken eller dikessystem rensas för att de skall bibehålla eller återfå sin ursprungligt avvattnande och produktionshöjande funktion. Sveaskog avser att öka omfattningen av dikesrensning. Därför behövs en kartläggning av behovet på deras marker. På samma gång behöver produktionseffekterna och livslängden på dikena utrönas. Studien genomfördes via en studie av befintlig litteratur om skogsproduktionseffekter efter dikesrensning och dikning samt förfall och livslängd hos diken.

Modellering av indunstning på Södra Cell Mönsterås

Evaporation is a part of the chemical recovery department at wood pulping mills. The purpose of evaporation is to remove water from the black liquor, which makes the liquor combustible. The process is very energy demanding, and having a well-functioning model of the system is of greatest interest. The model can then be used to study energy consumption and to test different control strategies. Two models have been developed during the master thesis.

Lagring av kyla i bergrum : Undersökning av ett nedlagt oljebergrum

There aremainly two trajectories to take. Eitheran installation of chillers needs to bemade or the rock cavern can be used tomeet the future demand of districtcooling in Solna, Sweden. Additionallythis thesis investigates the possibleuse of different techniques to utilizethe phase change energy of water.Simulation shows that it?s possible toutilize the phase-change energy of afluid; however it?s not economicallyfeasible due to the thermodynamiceffects on the Carnot cycle.

Inverkan av transgena grundstammar på fruktkvaliteten hos icke-transgena äppelsorten ?Jonagold?

Gene technology has become more and more attractive in plant breeding during the last twenty years. This is probably because it can readily improve the existing commercial cultivars that have only one or a few drawbacks by modifying one or a few genes without changing the main genetic constitution. In this regard, gene technology is more effective than conventional breeding.The aim of this project was to analyze the fruit quality of the non-transgenic apple scion ?Jonagold? grafted on non-transgenic and rolB-transgenic apple rootstocks. The rootstocks used were M9-rolB1, M9-rolB2, M26-rolB and non-transgenic controls M9 and M26.

Förbättring av U-värde i träkonstruktion för fönster med Aerogel

When constructing a building, a number of aspects must be harmonized in order for it to fulfill requirements ? a building must fulfill requirements such a load-bearing, conservation of energy and a good indoor environment by means of, among other things, moisture proofing .Moisture problems in buildings can affect health negatively. As we are increasingly staying in indoors, demands on a good indoor environment are higher.This work starts with examining moisture problems in slab-on-ground solutions, and then links the various scenarios to moisture problems in a concrete slab of a real building. The building with moisture problems is located in Årby by in Borlänge and moisture damage was found in the slab at an apartment adjoining wall.By reviewing literature written within the field of moisture problem, making hand calculations and modeling in the program Comsol Multiphysics, judgments are made to find explanations as to why the rise of moisture occurred in the building in Årby by.Generally, the following guidelines may be used to reduce the risk of moisture problems in slab-on-ground constructions:Drying of construction moisture before laying the floor material.Using draining layer beneath the slab, to prevent capillary suction.Using insulation under the slab, partly for comfort and to establish the temperature difference between the ground and the concrete slab.Avoid direct contact between the wood and concrete, due to degradation and fouling smells that normally occurs.If necessary, use additional vapor barrier.In addition to the above, there are various methods for moisture-proof and moisture-monitoring by design or by the method ByggaF suited for the entire construction process various events..

Den psykosociala arbetsmiljöregleringen : Med inriktning på arbetsrelaterad stress

This essay focus on work related stress and psychosocial enviroment in working life. The purpose of this study is to present a detailed description of regulation of the the Occupational Safety and Health Act and investigate how well employees are being protected by the law.I will also explain with the help of statistic which employees that most often suffer from work related stress and the results is discussed from a gender perspective.Work related phycosocial health is a big issue in todays workplaces, and people who suffers from stress are supposed to be protecteded by the the Occupational Safety and Health Act, but is that really the truth? The Occupational Safety and Health Act is a frame law, meaning the law is general and needs binding regulations to define the rules, and there is no such act about work related stress at the moment. No employer has ever been convicted for work related stress. At the same time the Occupational Safety and Health Act explains that the employer has a responsibility to take arrangement to prevent mental illness in working life.It?s mostly women who suffer from work related stress.
