Kartläggning av energianvändning under byggfasen vid nyproduktion av flerbostadshus

The energy consumption in the sectors of residential and public buildings is 40 % of the total energy consumption in Sweden. The main part, 85 %, of the energy use in these sectors is for operation of the buildings. The rest is used in the building process. When energy-efficiency measures are taken the energy use during the operation time decreases and the fraction of energy consumption during the building time increases. This project is carried out in cooperation with JM AB and concerns the energy use during the building time of production of blocks of flats at the building site.The main part of the electricity that is used during the production of apartment buildings goes into the heating of portacabins and illumination of the building during the construction phase.

Visstidsdirektivets implementering i svensk rätt : Har korrekt implementering skett?

The essays main intent is to examine whether there has been a proper implementation of the Council?s directive 1999/70/EG into Swedish law regarding the requirement for measures to prevent the abuse of successive fixed-term employment contracts. To achieve this purpose there is a need for an examination of current law. The essay also has some secondary purposes. One of these secondary purposes is the question of whether the implementation of the Council?s directive 1999/70/EG has lead to a reduction of the workers employment protection, which is closely connected to my main question and the violation case.

Utveckling av en HBV/PULS-model med sammanfogade markfuktighets- och responsrutiner

Soil properties affect the chemical composition of soil water. When studying transport of chemical substances through a basin, it is therefore important to know from which soil layer the main part of the runoff is generated. The aim of this study is to develop an HBV/PULSE model with merged soil moisture and response routines, which generates good approximations of groundwater levels. It should be possible to extend the model to simulate transport of substances and take into account which soil layer the groundwater level is currently in. The hydrological version of HBV/PULSE is used since there is no need to account for pH or alcalinity at this stage.

Termoelektrisk lagring i system med fjärrvärmeproduktion

With increased deployment ofintermittent renewable energy, such aswind and solar power, energy storagebecomes necessary to help reduceproduction peaks. Thermoelectric EnergyStorage is a method still in researchphase, which stores electricity in hotwater at a temperature of 120 ° C. Thisthesis aims to examine whether theThermoelectric Energy Storage would bepossible to integrate into existingpower generation such as a combined heatand power plant, and how the technologypotentially could function in theelectricity market. ThermoelectricEnergy Storage consists of a chargingprocess and a discharging process, bothoperating by the working fluid CO2. Toincrease the efficiency of theThermoelectric Energy Storage, wasteheat from the district heating networkis integrated.A model of the Thermoelectric EnergyStorage has been developed and it wascalculated by thermodynamic propertiesof the working fluid, CO2, in thevarious process steps.

Storage stability in a milk based UHT-beverage : effect of pH, carrageenan and storage time

The different characteristics of many food products, such as aroma and texture, changes during storage time and become undesirable. The reason is instabilities within the product which become prominent as the product ages. These changes in characteristics are quality losses caused by changes in the product?s intrinsic and extrinsic environment. The stability in UHT-milk and beverages similar to it have been studied in the past decades and a certain focus have been on age gelation which is a common defect in these type of products.

Just In Time : Effektivisering av materialflöden med hjälp av principer från Inventory Management och Production Management

AbstractManagement is a field that started getting attention in the beginning of the 20th century by Frederick Taylor. His publication is called the Principles of Scientific Management and is based on the principles of using scientific methods to find the best way of conducting each operation within a production facility. Many of Taylor?s principles may appear obsolete today but the matter of an effective material flow is still highly current. Efficiency is the relationship between the input into an operation and its result.

Riskkapitalägande i den svenska välfärdssektorn - kortaste vägen till (skatte-)paradiset

This thesis studies whether private equity owned firms within the Swedish welfare sector distinguish themselves in terms of tax planning and short-termism from a control group consisting of other privately owned welfare firms. For the first time, the comparison is made on the entire welfare sector, between 14 matched pairs within education, health care and elderly care. We use financial metrics associated with tax planning and short-termism in sign tests to examine whether the private equity owned firms differ from our control group. The financial metrics tested are actual and paid tax rates, level of interest, book-tax gap, investments, personnel expenses per employee, and cash earnings. We find that the private equity owned firms in terms of tax planning only differ in the level of interest, while no notable differences are found in terms of short-termism..

Den heliga treenigheten : en fallstudie av kommunikationsprocessen mellan ledning, anställda och säljbolag på Alfa Laval AB

The manufacturing industry is currently in a short-term downturn while the competition is increasing. The result of this is that companies must find new ways to bring out their products. Traditional competitive strategies, such as low pricing, is not sufficient today as the customer is inquiring something more than just a good product. Higher demands are presented on an accurate, well functional, communication between customer and companies, as this has become an important strategic factor in achieving long-term profitability.The aim of this independent project was to analyze and evaluate the communication process between a company and its sales companies.In order to illustrate this process, a case study was carried out at Alfa Laval, their sales companies and employees at their distribution center in Tumba. In order to see the differences in attitudes between the management, the sales companies and the employees regarding communication and involvement a gap analysis were used.The theoretical part of the study considers theories about business mission, communication, involvement, quality and creating value.The result showed that a smaller gap exists between the sales companies and the management while a slightly larger one exists between the employees and the management.

Skärgårdsliv för rekreation : En undersökning av möjligheterna till vistelse i Stockholms Skärgård

AimThe aim of this study has been survey the possibilities for short-term stays in the Stockholm Archipelago for people without their own means of transport, own equipment and/or experience of outdoor life.To fulfil this aim, the following questions were formulated:? What communications are available to chalet parks in the Stockholm Archipelago?? What overnight accommodation is available in the chalet parks in the Stockholm Archipelago?? What activities can be pursued in the Stockholm Archipelago?? What is the financial cost of travelling to and staying in the Stockholm Archipelago for a week?MethodWe chose to use six interviews and three observations in order to gain as much insight as possible. Interviews were conducted with Claes Petterson at Waxholmsbolaget, a company that provides transport services in the Archipelago, and with managers for five chalet parks: Rolf Andersson for Finnhamn, Per Englund for Grinda, Arne Johansson for Rånö, Pär Hjärtström and Peter Hösöyen for Gålö and Anders Bedinger for Gålö and Nåttarö. The interviews were recorded in writing and on tape. Observations were carried out at three chalet parks, i.e.

Barnperspektiv inom socialtjänsten : En kvalitativ undersökning av socialsekreterares hantering av barnets bästa

 The aim of this study was to examine how social workers perceive and interpret the term ?barnets bästa? (?The best for the child?), within the framework of investigatory work and enforcement of Swedish law, which is carried out by the Social Services. We wanted to investigate if the interpretation of the term had any causal effects on the work carried out by social workers. Seven social workers from two municipalities participated in this study in which we used qualitative semi-structured interviews based around two vignettes. We focused on age, experience, legislation, and external circumstances to gain insight into how these factors alter social workers? perception of the term ?barnets bästa?. Our theoretical approach was based on two theories on social constructivism.

Samverkan mellan socialtjänst och polis, när ett barn misstänks för ett brott : - En kvalitativ studie, ur ett myndighetsperspektiv

Interdependence between seed age and aerated steam treatment intensities

Aerated steam treatment is a modern and environmental friendly method for seed borne fungus sanitation, mainly used on cereals. The method involves exposure to heat and high humidity, factors which are known to induce a fast ageing of seeds, thus resulting in reduced storability. This thesis clarifies the interdependence between seed age and the aerated steam treatment intensities. Two studies were carried out in this thesis. In the first study the storage longevity of seeds treated with aerated steam was examined. The second study investigated the shelf-life of the pre-tests used to determine the aerated steam treatment tolerance of a seed lot, by testing the treatment tolerance of seeds aged prior to the treatment.

Long-Term performance of Swedish IPOs - 1990-2002

We have performed a study much similar to Ritter?s (1991) about long-term aftermarket performance of IPOs on the Swedish market during the years 1990 to 2002. The study resulted in evidence for that Swedish IPO do underperforms their benchmark-portfolios during a 36-months period. Though, the grade of underperformance depends of the chosen benchmark. The study is mainly focused on a particular benchmark, a portfolio of non-issuing firms matched by size and sector.
