Värmebehandlat trä ? att inhämta synpunkter i produktutvecklingens tidiga fas :
This study is a part of a Swedish research and development project that is about heat-treated wood and is led by the Swedish University of Agricultural Sciences and Luleå University of Technology. Products that are heat-treated already exists on the market, foremost the Finnish brand ThermoWood®, bur the project group want to find out if it would be possible to start a Swedish production with somewhat different applications than what is common today.
The heat-treated wood has many attributes that have changed in the heating process. It becomes more biologically durable, it gains stability in form and dimensions and it becomes darker and looses several unwanted extractives such as resin. Disadvantages that can be mentioned are that the wood becomes fragile and the strength properties changes.
My main purpose with this study is to look into customer involvement in the early phase
of product development. I also want to find out if the customers I interview think that the product is worth working with, which means start a Swedish production.
Ett vårdinformationssystem i vårdens frontlinje : En fallstudie om Cambio Cosmic på en vårdcentral i Landstinget Kronoberg
In healthcare there is a rapid development towards introducing and implementing a wide range of information technology (IT) to aim for higher quality and more effective care. A common health information system (Cambio Cosmic) has been implemented in Landstinget Kronoberg. Clinical microsystems are the frontline units where staff and pa-tient meet. When the conditions in the microsystems are changed, it is interesting to de-scribe and analyse the consequences.The purpose of this study is to describe how health care staff uses a health information sys-tem and how they experience its functionality in their patient work. Initially, a literature re-view about the use of health information system was undertaken, followed by a qualitative case study based on interviews about how healthcare staff describes their reality.

Processjämförelse : säljprocessen inom ett internationellt företag
Sales is the foundation for all commercial business and companies that have the best sales process in conjunction with efficient deliveries will do well in the long run. The author of this report was tasked by the Organisation in South Africa to study new/alternative ways of attracting Swedish companies to South Africa and sell the services of the Organisation to these same companies (defined as the sales process in this report) by analysing how similar international service companies do the same. A benchmarking process has been conducted with four similar service organizations in South Africa to examine how these companies work in comparison to the Organization. Surveys have been used for purposes of this study, as the methodology is well suited to provide the author a view on the opinions, perceptions and experiences of the respondents.The project aimed to develop new methods to attract Swedish companies to South Africa or improve and streamline the existing methods. The aim was also to develop new ways to sell the organization's services to Swedish companies.The study concludes that there is little focus on marketing of services within the Organisation.
Analys av system för rening av avloppsvatten i en anaerob membranbioreaktor
The most common way to treat wastewater in Sweden today is by a combination of an activated sludge process and a chemical treatment. These processes are not very energy efficient and may not be the most environmentally friendly. That is why it is interesting to evaluate new alternative methods to see if they can be less harmful to the environment and help to a lower resource consumption. New techniques are tested in a pilot installation at Hammarby Sjöstad, Sjöstadsverket. To be able to evaluate these techniques in a wide perspective system analyses are conducted where different impacts can be considered, advantages and disadvantages in the systems.Five system structures for water treatment have been constructed in Matlab/Simulink in this study.
Konceptuell design och utveckling av hybridfordon
This report covers the conceptual design of a new one person hybrid vehicle that is to be fast and convenient to drive on the roads. The vehicle is most of all supposed to be used as a commute vehicle but can also be used at other occasions as well.During the work with this project the group has focused on three larger areas, the outer design (body), wheel chassis and an ergonomically designed interior. The group was not able to just create these parts in 3D to get a trustworthy vehicle, hence number of other components and details were also created to get a better entirety.The outer design starts with idea generation and sketches and ends with a 3D model which is rendered to show how the final product is going to look. The design of the body has been going on during the entire work process due to new ideas and improvements that seemed interesting and had to be changed.The wheel chassis also started with idea generation, research and sketches. It ended up with a simulated 3D model which later on was mounted on the vehicle body to show how the vehicle is going to perform during usage.
Organic acids in liquid feed for pigs - palatability and feed intake
Fermented liquid feed is well known for its health promoting effects on piglets. High levels of lactic acid are desired in the feed together with low levels of acetic acid and certain biogenic amines. Limits for acetic acid have been suggested to be 30-40 mmol/kg to avoid a decreased palatability of the feed; however, few studies have been performed. The purpose of this trial was therefore to examine which levels of lactic acid and acetic acid that can be accepted in a fermented feed without affecting the feed intake and thus the weight gain of the pig. A total of 60 pigs (Yorkshire/ Hampshire) were used in a trial during two weeks, between 9-11 weeks of age.
Laborationsmätning av vindtäthetens betydelse för en väggs U-värde
To fulfill the climate target that EU and the Swedish government have decided to apply, it becomes increasingly important that the energy efficiency of existing buildings and making new buildings energy efficient as possible. Of Sweden?s total energy consumption in 2011 was 40% used by residential and service. Of the 40% of the energy consumption was 60% used for heating and domestic hot water. A report from year 2012 shows that one reason why the heating volume is so great could be due to underestimating on the energy consumption for the heating in the planning of the building.
Kontrolltorn : En informationslösning för tredjepartslogistik
The demand for shorter lead-times and increased delivery reliability puts pressure on companies to provide more efficient logistic services. One strategy to deal with this demand is by outsourcing logistics to a third part. The development of logistics information systems enables increased control over business supply chains. This is why Green Cargo aims to create a Logistics Control Tower (LCT) solution to provide it?s customers with better information with higher availability.
Determination of anthelmintic resistance of Haemonchus contortus to three classes of anthelmintics in a Kenyan sheep flock based on results from faecal egg count reduction test
Haemonchus contortus is the most important bloodsucking gastrointestinal nematode in small ruminants worldwide. It is often controlled by anthelmintics. Even though other methods to control are available, the most efficient way to treat an animal with clinically manifested haemonchosis is to use one of the available broad spectrum anthelmintics: benzimidazoles (BZ), macrocyclic lactones (ML) or imidothiazoles-tetrahydropyromidines or the narrow spectrum drugs salisylanilides or nitrophenols. Anthelmintic resistance (AR) against all groups of anthelmintics in nematode parasites has been reported from many countries, and even multiple AR has been observed. In this study I have investigated the resistance levels to all major classes of broad spectrum anthelmintics in a naturally infected flock of sheep of Red Maasai sheep (RM), Dorper sheep (D) and their offsprings on a research farm in Kenya.
Stopover duration and field site selection by whooper swan (Cygnus cygnus) at Lake Tysslingen, Sweden
The aim of this study was to increase the knowledge about whooper swan (Cygnus cygnus) ecology to enhance the ability to predict and also to prevent the crop damage they cause. The largest proportion of damage in Sweden has been reported at stopover sites during spring migration in February, March and April. Therefore, this study focused on an important stopover site, Lake Tysslingen, situated in south-central Sweden. Specifically, the relation between the duration and period migrating swans stage at the stopover site and mean temperature (measured at three different weather stations) for the years 2001-2010 was studied. Furthermore, the swans´ selection for certain fields in relation to field type, distance to roosting site, a supplemental feeding site and forest edge within agricultural land surrounding the lake was analyzed.
Energy efficient storage of biomass at Vattenfall heat and power plants
Storage of biomass is often associated with problems such as heat development, dry
matter losses and reduction of fuel quality. The rise in temperature can potentially
cause a risk of self-ignition in the fuel storage. Moreover, emissions from storage piles
can cause health problems in the surrounding. The dry matter losses and reduction of
fuel quality can have economical effects. The aim of this thesis project is to develop
guidelines on how to store large amount of biomass at Vattenfalls heat and power
plants in an optimal way.
Kostnadseffektiv svaveldioxidreduktion : en studie där ett optimalt svenskt mål jämförs med ett internationellt mål
In Sweden the work of reducing acidification and its prime cause; emission and deposition of sulphur dioxide, has been going on for decades. Despite of all the work that has been done the positive progress in the acidified areas is slow. This is partly due to a long recovery time for the acidified areas but also because the reductions of emission and deposition of sulphur dioxide have not been large enough.
Emissions of sulphur dioxide from land based source in Sweden are estimated to 34 000 tons in the year of 2010. During the same year, approximately 182 000 tons of sulphur dioxide will be deposited over the Swedish territory.
