The company Olofsfors AB manufactures drive belts for forest machinery, known as ECO-Tracks, and abrasion-resistant steel and cutting edges for graders, excavators and tractors, known as Bruxite and SharqEdges. Manufacturing these products requires the steel to be heated and molded, then submerged in water and hardened. The water used in the hardening of steel is pumped to the process from pits below the floor and then pumped back to the pit after it?s been used. Since the temperature of this water rises after being used to harden the steel the temperature of the pumping pit needs to be adjusted to maintain its setpoint of 21°C.

Energy consumption is at present a major political issue, and numerous projects that comprise many nations are currently in process to increase energy efficiency and bring down energy dependency. As a member state of the EU, Sweden now faces the challenge of implementing substantial energy-saving measures until the year 2016. One of these measures is the project ?Green Islands? financed by the EU that intend on creating sustainable islands in areas around the Baltic Sea. The Archipelago Foundation leads the project that concerns the Stockholm archipelago, where focus has been placed upon decreasing energy usage in businesses and services on Utö among other islands.

To be able to handle tomorrows need for limited energy consumption we need to reduce our use of energy. The building sector stands for around 40 % of all energy consumption in the society. The government has put up a goal to reduce the energy consumption in our buildings with 20 % by year 2020 and 50 % by year 2050 compared with year 1995. To be able to do reach that goal we need a more energy efficient building stock.The main part of the energy used in our buildings is used for space heating. By installing ventilation systems with heat recovery on the exhaust air it is possible to use the heat-energy in the exhaust air to warm up the incoming air.

Authors: Fanny Edstam & Joacim KettilTitle: Between Askim and Angered. A quantitative research of media's presentation of individuals in different socio-economic residential areas.Level: Bachelor of JournalismLocation: University of GothenburgLanguage: SwedishNumber of pages: 41Gothenburg is a city that struggles with the issues of segregation. Residential areas like Askim are poorly integrated and areas like Angered have a high amount of immigrated inhabitants. Our hypothesis, with this in mind, is that one can assume media reports from different socio economic residential areas in different ways. The assumed difference in reporting can have aneffect in the readers beliefs that an area can be better or worse than it actually is.

Diet and lifestyle are closely interrelated and believed to have a significant influence on four major public diseases - cardiovascular disease, cancer, hypertension and obesity, but also affects functional deficiencies like gluten- and lactose intolerance. Health added-value foods are thought to reduce health-related risks or delay the onset of these major diseases. Therefore, interest among scientists, researchers and the public in general has been growing remarkably over the last decade regarding these special foods. The Swedish market seems to be a good target for health added-values food. However, as there are many risks and cost factors involved for companies to enter the market or invest in R&D, it is important to take a step back and analyze the current market situation.

The projects objective is to find an alternative method of heating (the current method being via electric heating) the sewage treatment plant on the island Utö in Stockholm?s archipelago in order to reduce the energy consumption and ultimately the cost for heating the plant. The project is given by ?Skärgårdsstiftelsen? (The Archipelago Foundation) and is a part of the larger EU-project ?Green Islands?.A model for the plants total heating demand is established in order to get a good perception of how much money can be saved using alternative heating methods. The heating demand model gives an annual heating demand of approximately 32 500 kWh and a maximum heating power demand of around 24,7 kW.

Small business enterprises have escalated in Sweden during the last decade. However, new established companies are struggling to maintain their selves during the startup process and according to a survey from Tillväxtanalys, only 68 % of startup companies from 2008 were still active three years later. One of the main reasons is lack of capital and the most common approach to finance companies is to apply for a bank loan. In other words, commercial banks are of great importance for new businesses. Although, the problem arises when there is no previous history from the new businesses that the bank could base its credit assessment on.

Green manuring is a way of creating an organic fertilizer by growing a crop that is mowed down. Besides the fertilizing effect this method has been shown to have a positive influ-ence on soil organic matter as well as weed flora, and green manure is an important me-thod of weed control in organic farming in parts of Sweden. However, the release of nu-trients from the green manure varies and can therefore be difficult to control. Risks for losses of nutrients are also present. Although the area of organic farmland is increasing in Sweden, the use of green manure is decreasing.This report contains a literature study which compiles research on the functions of green manure in a cropping system and also how the crop can be used if harvested, for example to produce biogas.

Today there are a big need for a system that delivers overview of all available units for different municipalities and shipping- and security companies due to the increasing requirements for efficiency. The purpose with this graduation thesis is to find out which systems that is suitable to use while developing cost-effective software for positioning and to produce a prototype for such solution.This assignment has been done at the request of PocketMobile Communications AB. PocketMobile is a company that are specialized on delivering modern mobile software solutions and systems to companies with their own vehicle fleet or mobile workers.This master thesis can be split into two separate parts, the theoretic- and the practical part.The theoretic part includes producing a number of functional requirements in cooperation with PocketMobile and comparing the available systems against the function requirements.The practical part deal with the development of a prototype that demonstrates the software recommended. The development tools that best matched the functionality requirements when the selection was made in May 2007 were Map24 and OpenLayers. The system that was selected to use while developing the prototype was Map24, because this product matches all of the requirements and it is also suited for professional usage regarding support, scalability and reliability.

This thesis considers the development of the software for an, newly developed, embedded real-time control system, based on a Periferal Interface Controller (PIC). The control system is developed to be used for several different applications. In this thesis work, software for two different applications are developed. The first task is a time controlled system, while the other task is implementation of aPI-/PID-controller. A user interface is also developed and implemented.The time controlled system is an automatic horse feeder, which is used for feeding horses at certain predefined points in time.

  SammanfattningFöretag har alltid drabbats av ekonomiska svårigheter och gått i konkurs. Detta faktum harlänge intresserat forskare och legat till grund för en mängd studier inom området.Kassaflödesanalysens användbarhet vid konkursprognostisering har länge diskuterats ochtidigare forskning har visat på varierande resultat. Eftersom en kassaflödesanalys visar på detfaktiska in- och utflödet av pengar i företaget tror vi att den kan utgöra en viktigare indikatorpå om ett företag befinner sig i kris än resultat- och balansräkningen, som lättare kanmanipuleras. De flesta företag som går i konkurs är mindre företag, som inte omfattas av det lagstiftande kravet på att upprätta en kassaflödesanalys. Därför anser vi det intressant att studera vilket stöd en kassaflödesanalys kan utgöra för att förutsäga en konkurs.Detta mynnar ut i vår problemformulering:· Hur kan en kassaflödesanalys bidra till att prognostisera en framtida konkurs av små aktiebolag?Syftet med vår studie är att undersöka om tillämpningen av en kassaflödesanalys påverkar prognostiseringen av en eventuell framtida konkurs i ett aktiebolag.

The aim for the study was to examine a harwarder´s (combined harvester-forwarder) productivity when harvesting forest fuel in first thinning stands that contains Lodgepole pine and calculate the economy of the harvesting work and estimate the quality of the thinning . The field study area where located near Arvån, about 15 kilometres south ?east from the city of Lycksele. The field studies were taken place in three different stands. All tree stands had the same tree age, but the tree species combination and the density varied.

Background: Surgical complications has been the main cause of medical injuries and deaths worldwide. In 2008 WHO developed the checklist for safe surgery to reduce the number of surgical complications. The objective of the checklist is to strengthen already established safety routines and contribute to better cooperation and communication. Research shows that compliance to the checklist is deficient, which can affect patient safety.Aim: The aim was to study the extent to which theatre nurses participate in the use of the checklist.Method: Observational study was conducted with a descriptive design and quantitative approach. 24 observations were carried out with aid of an observation protocol of two surgical units at a hospital in central Sweden.Result: The results showed that Timeout initiated widely but compliance to all items was considerably lower.

BackgroundWhen women have breast pain this usually is not associated with myocardial infarction, which results in that they get less attention and wrong treatment. The nurse has an important role in informing and educating patients and families during hospitalization, which is usually short. Continuous training, written information and repetition for patient and family throughout the hospital stay are of considerable importance to clarify that the patient understands and to reduce the anxiety of being discharged.AimThe aim is to describe nurses' experiences of caring for older women with myocardial infarction.MethodsA qualitative method was used. The collection of data was done by six interviews with nurses in geriatric care and elderly care. Dataset has been processed based on a content analysis and divided into subcategories and main categories using meaningful units.ResultsNot having knowledge of older women with myocardial infarction was expressed as frustrating and nurses described how they were afraid to ask their colleagues.
