Vätskekopplade värme- och kylåtervinningssystem Utveckling av ett verktyg för energiberäkningar
According to a decision of the European Commission, measures are to be taken to reduce the use of energy in the EU. The goal is to reduce it by 20 % compared to the current use. This shall be done to the year 2020 (European Commission, 2011). One industry that use large amounts of energy is the construction of buildings which account for almost a third of the energy use (Brogren, 2012). The major part of the energy that is used in the construction industry is not used when the buildings are built, but rather during the rest of their subsequent lifetime.
MÄNNISKA OCH KRISTEN GUSTAF WINGRENS SKAPELSETEOLOGI Analys av en accentförskjutning från juridisk teologisk metaforik till biologisk teologisk metaforik
Titel: Human being and Christian ? creationtheology of Gustaf Wingren.Analysis of an accentshift from a juridical theological metaphor to a biological theological metaphor.Author: Tove Pilroth.The purpose of the essay is to analyse the meaning and the consequences, in a critical and constructive way, of an accentshift of interpretation and understanding of the gospel, from a juridical theological metaphor to a biological theological metaphor. The purpose is presented in the frame of the creationtheology of Wingren. To be able to make the research and to answer the purpose of the essay, the following questions are essential:The human being is captive and redemption is liberation. If we are serious about that the gospel gives the human being rehabilitation, satisfaction, liberation and a life and a future with God, the essential question is which metaphor, a juridical or a biological, that speaks to the human being in the best way? What is the meaning of an accentshift from a juridical to a biological metaphor? How does the creationtheologhy of Wingren, from a biological metaphor, meets the situation of the existence for the human being, her longing for life, health and meaning? What kind of theological resources are present in the creationtheology of Wingren, in the confrontation with future theological challenges?The essay is stressing the need of pluralism in the interpretation of the gospel.
Utveckling och tillämpning av en GIS-baserad hydrologisk modell
A distributed hydrological rainfall-runoff model has been developed using a GIS integrated with a dynamic programming module (PCRaster). The model has been developed within the framework of the EU-project TWINBAS at IVL Swedish Environmental Research Institute, and is intended for use in WATSHMAN ? a tool for watershed management developed at IVL. The model simulates runoff from a catchment based on daily mean values of temperature and precipitation. The GIS input data consist of maps with soil type, land-use, lakes, rivers and a digital elevation model.
Optimering av nanocellulosa för tillämpning som papperstyrkeadditiv
Syftet med projektet var att undersöka hur homogeniserings förhållanden (tryck antal passager och därmed energiinsatsen) vid framställning av MFC (mikrofibrillär cellulosa), från enzymatiskt förbehandlade pappersmassafibrer påverkar hållfastheten av papper förstärkt med MFC. Arbetsgivaren för projektet var Innventia och det laborativa arbetet har utförts i deras lokaler. Fördelen med att använda MFC som tillsats i papper är att arket blir starkare [1]. Detta medför att en mindre mängd material kan användas till ett material med liknande styrkeegenskaper.Vid Innventia används för närvarande en homogenisator för att delaminera (sönderdela) cellulosafibrer till fibriller och fibrillaggregat och därmed producera MFC. Homogenisatorn kan köras vid olika tryck, samt att cellulosafibrerna/MFC kan låtas passera genom homogenisatorn en eller flera gånger.
Analys av designalternativ för snabbare dynamik i kolkraftverk med koldioxidavskiljning
Combustion of fossil fuels is today the dominating source of energy. During combustion,carbon dioxide is formed. The carbon dioxide accumulates in the atmosphere,which raises the global average temperature on earth through the so called greenhouseeffect. The only way to reduce the emissions of carbon dioxide from combustionin a coal fired power plant is through carbon capture and storage (CCS).Post-combustion capture is a technology to separate carbon dioxide from the uegas after the combustion for efficient transport and storage. The steady state operationof coal fired power plants with post combustion capture has already beenthoroughly investigated on a pilot scale, however much work remains to investigatethe plants dynamic operation.
Näringsretention i återskapad våtmark på betesmark : studier av en mad vid Bornsjön
It is important to construct or recreate different types of wetlands and study their retention of nutrients, since knowledge of their effectiveness in this matter is poor. In 2003 a wetland was constructed on an old meadow on the western shore of Lake Bornsjön in central Sweden. The main purpose of the wetland was to reduce the amount of phosphorus entering the lake, which is the back-up water supply for Stockholm when the city cannot obtain water from Lake Mälaren. Large areas around Lake Bornsjön consist of agricultural land and the nutrient concentrations in the inflows to the lake are usually relatively high (approx. 1 mg/l total nitrogen and 0.05-0.1 mg/l total phosphorus).
Resource planning for internal logistics : A tool designed for the material handling department at Scania Axles and Gearboxes
This master thesis is performed at Scania Axles and Gearboxes, a production plant located in Södertälje. Within the plant axles, gearboxes as well as central gears are assembled from components to finished products. All production is conducted on production lines, with a pre-determined rate, which is supplied with components by the material handling department. Since the production quantity and the mix of product variants produced on the production line is customer order-based, the number and type of components needed for production as well as appropriate staffing within the material handling department is difficult to predict. Scania is currently using a number of different resource planning tools for each material handling-department within Axles and Gearboxes to visualize the workload within the departments.
En dynamiskt fungerande arbetsgrupp : en fallstudie inom administration
På ett vis är grupper för organisationen vad elden var för våra förfäder, om de förstås och används rätt, utgör de anmärkningsvärt kraftfulla och flexibla verktyg: om de missförstås eller används felaktigt blir de destruktiva krafter. Likt elden kan grupper skapas eller uppstå spontant, och i likhet med elden är de farligast när de ignoreras. Syftet med uppsatsen är att identifiera förbättringsområden inom en organisations verksamhet som ska prioriteras, där ett förbättringsområde ska vidarutvecklas inom ett projekt. Det förbättringsområde som valts är att analysera hur den administrativa enheten kan bli en dynamiskt fungerande arbetsgrupp samt att ta fram verktyg och strategier för hur det ska gå till utifrån målen:1) Vad medarbetarna upplever är bra2) Vad medarbetarna kan utveckla3) Hur gruppen kan arbeta vidare som gruppsamt för att få svar på mina inledningsfrågor: vilka faktorer påverkar att jag som människa/medarbetare känner att jag tillhör en arbetsgrupp som når resultat och är en del av min helhet? Vad är det gruppen behöver för att kunna uppnå effekten av att vara en väl fungerande och dynamisk arbetsgrupp. För att uppnå syftet och målet har en fallstudie genomförts där samtliga medarbetare i den administrativa enheten har fått besvara en enkät/frågeformulär vid ett gemensamt tillfälle. Enkäten har bestått av både öppna och fasta frågor och utgör kvalitativ forskning.
Massbalansmodellering av fosfor i ett åländskt kustområde : en utredning om lokaliseringen av Lotsbroverkets utloppsledning
This report is commissioned by the Water and Sewage Agency in The City of Mariehamn, Åland. The basic aim is to investigate positive or negative effects of a relocation of the sewage pipe from a wastewater treatment plant, Lotsbroverket. The environmental licence of Lotsbroverket is to be revised and The Environmental Appeal Board at Åland?s Government and Administrative Board has made demands that several possible locations in an outer water area should be examined. The present location of the sewage pipe is in Svibyviken, which has been classified as an ?inner water area?.The objective of this work is to study to which extent the nutrient loading from Lotsbroverket influence the environmental conditions in Svibyviken, and to investigate the suitability of different locations of the wastewater pipe from Lotsbroverket.The way a coastal area looks, i.e., its morphometry, determines to a large extent its ecological characteristics.
Outsourcing av urval och inköp : En studie av hur bibliotekariens kompetens och yrkesroll påverkas av Bibliotekstjänsts profiltjänster
Traditionally, the majority of Swedish public libraries have carried out most of their acquisitions through Bibliotekstjänst's binding booklets. In recent years, however, many libraries have complemented the binding booklets and other services from Bibliotekstjänst by other ways of acquiring books, such as Internet bookshops, while other libraries have stopped using the binding booklets altogether. There are various reasons for this development, such as Information Technology making it possible for librarians to compare prizes and services from different retailers. Another important reason is the need for public libraries to meet new needs from their patrons, while remaining on a restrained budget, which often causes a need for reorganization of staff and resources.As a way of meeting the new needs for libraries, Bibliotekstjänst has created Profile Services (profiltjänster), a service in which a library outsources its acquisitions to Bibliotekstjänst. The staff of the library, in dialogue with Bibliotekstjänst, design a profile for the acquisitions for the library in question, in order to determinate which types and genres of literature the library and its patrons are requesting.
Resursers roll för tillväxt i små och medelstora företag : hur kan tillväxt skapas?
Tillväxt är ett mångfacetterat begrepp som idag mäts med olika mätinstrument såsom omsättning, resultat eller anställning. Olika mätverktyg gynnar företag olika och graden av tillväxt är beroende av hur och vad som egentligen mäts. Begreppets innebörd är även otydligt inom forskning då det definieras olika i olika studier. Problem uppstår därför när jämförelser mellan olika studier görs.
Företag jämförs ofta med avseende på hur mycket de växer och de starkast växande företagen hyllas och ses som framgångssagor. I Sverige delar Dagens Industri årligen ut pris till årets snabbast växande företag och utser dessa till Gaseller.

Optimalt råvarulager för biobränsleföretaget :
This report was written as a final thesis within the Department of forest economics at the Swedish University of Agricultural Sciences as a completion of the M.SC Forestry programme. The aim of this study was to create a model that, with respect to given stock levels, temperature, fuel usage and fuel price, would identify the optimal levels for purchase of bio fuels, optimal levels of incineration of bio fuels and the sum of the present values of all costs. The model would be applicable for a larger district heating plant.
Data regarding temperature were received from SMHI. Information considering fuel prices was taken from the Swedish Forest Agency and the facts about fuel usage were collected from a large district heating plant, located in the southwest of Sweden. For the temperature, a sinus curve was adapted to describe the temperature over a year.
Strömmar av vatten och politik - en studie om policyprocesser och anpassning.
One of the distinguishing features of successful societies is the ability to adapt to change, bothsocial but also natural changes like climate change. Climate change is a complex, dynamic,non-linear process with a great deal of uncertainty concerning the time perspective, risks andconsequences. A combination of factors like climate change, geographical vulnerability, adensely populated and highly built up coast line along with factors like deficient handling ofsurface runoff and a large usage of ground water leads to an increasingly vulnerable society. Italso puts a greater pressure on the society to have preventive measures in place.The number of actors working with preparing society to the expected impacts of climatechange and variability is increasing. However more than half of Sweden?s municipalities donot consider changing climatic conditions when planning, and many times even allow theconstruction of new living areas in known climatically vulnerable areas.
