Koldioxidlagring - realitet eller utopi? : En komparativ fallstudie med syfte att undersöka potentialen för koldioxidlagring i geologiska formationer och biologiska sänkor och dess förmåga att bidra till hållbar utveckling
To curb greenhouse gases and mitigate climate change is one of the biggest challenges human society face today. Carbon dioxide (CO2) has accumulated rapidly in the atmosphere as a consequence of burning of fossil fuels and deforestation. The aim of this study is to explore two methods to store carbon dioxide in geological formations and biological sinks. The aim is also to discuss the two mitigation options from a sustainable perspective and whether it can lead to a better environment and benefits for local and global societies. The research questions are: Which method to store carbon dioxide, geological or biological, is the most effective? Which method to store carbon dioxide, geological or biological, has the greatest potential to promote sustainable development for local communities?The method used is a comparative case study and presents four case studies that explore the potential for CO2 storage offshore in Norway and Brazil; and in tropical forests in Mexico and Brazil.
Kalvens beteende i olika uppfödningssystem :
The purpose of this literature review was to investigate how the rearing systems influence the behaviour of dairy calves. Calves are social animals that form groups within the herd where play and social licking between calves are important social activities. Suckling is a complex behaviour and essential for the calf's survival. In the modern rearing systems the calf is usually separated from its mother soon after birth. Calves are then kept in individual pens, group pens or, more rarely, with a foster cow.
Bastu-frigidarium,energieffektivt system för återhämtning
Sweden is considered to have one of the world's highest animal welfare standards in agriculture. Despite this, there are shortcomings in animal husbandry. One example is overcrowding, which is a way to increase stock size without making costly investments in the buildings. It can be carried out systematically to increase profitability or due to, for example uneven calving during the year. The European Commission criticizes the fact that stocking density is not controlled under Swedish welfare inspections.
Nätverksbaserade informationssystem : Standardprotokoll ANSI Z39.50/OSI SR
This master thesis examines the development of the two earlier independent IR protocols Z39.50 and SR (Search and Retrieve, ISO 10162/10163), now Z39.50/SR, from the beginning of the 80s to 1996 and their functionality in the client/server environment.Z39.50 applications in library systems will allow easy access to information regardless of platform or location. The use of Z39.50 will create a new user environment. Almost all the library systems of the market support the Z39.50 and surprisingly the use of it in Sweden lied on a very low leve! in 1996. This thesis was followed-up by an interview and a questioner among the Swedish Z39.50 users. They could see a huge potential of development concerning the future IR process.
Från föreställningar till relevanta system - Linköpings universitetsbibliotek analyseras med hjälp av Soft Systems Methodology
The background to this thesis is the impact of information technology on libraries and librarywork. If information technology causes changes in the tasks and work of libraries, thenlibrary organisations should also change. It is important to engage and inform the staff if suchchanges are to succeed. This thesis investigates the notions about library tasks and librarywork among eight "middle-managers" at Linkopings universitetsbibliotek.The investigation is based on interviews and then analysed with Soft Systems Methodology(SSM). By identifying the "Weltanschauung" of the staff, the thesis tries to create logicallydesirable and culturally feasible models of systems relevant to the situation at Linkopingsuniversitetsbibliotek.
Konsekvensutredning inför införande av koncerngemensam systemplattform : Vad skulle det innebär att införa SAP på KSU, Kärnkraftssäkerhet och Utbildning AB
The implementation of large IT-systems is a complex area where many aspects have to be taken into account.KSU, Kärnkraftssäkerhet och Utbildning AB, is a small company in the Vattenfall group that is increasingly being urged to implement SAP, one of the largest ERP-systems on the market. Vattenfalls purpose with SAP is to centralize certain processes within economy that are common to all the companies in the group, this to gain benefits with economics of scale. However, KSU is not convinced that SAP is a suitable system and that the common processes apply to them.The purpose of this degree project is to investigate if SAP is a suitable system and if KSU will benefit from a transition to SAP. Three perspectives were applied to further specify important areas of the main question. From a technical point of view KSU:s demands on a system was mapped against SAP.

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.
Managementperspektiv på grisproduktion i Lojsta :
At the farm Fride, in Lojsta at the Southern part of Gotland, my family runs a pig production with 80 part-integrated sows in a ?Familybox-system?. The main parts of the facilities are from the early 90´s and have done their job. The production results have the last years decreased because of new infections so we have to do something before shifting ownership!
This degree thesis is meant to answer the question about which the optimal extension would
be today. By studying literature, use my own experience and make lots of calculations, I try to find out different opportunities.
Faktorer som påverkar magnesiumabsorptionen i våmmen hos kor
In metabolism Mg plays an important role because it affects many cellular enzymes in the body. The energy metabolism and protein synthesis are dependent on Mg as an enzyme activator, Mg is also involved in the synthesis of RNA and DNA. Absorption of Mg primarily takes place over the ruminal epithelium in ruminants. The main storage of Mg is in the bones but that can only be reached if the cow is in great need of calcium or phosphorus, it's a hormonal regulated process that induces catabolism of bones. Free and available sources of Mg are found in soft tissues and in the extra cellular fluids that includes cerebrospinal fluids and blood.
Bättre enskilda avlopp i Sigtuna kommun : möjligheter för bebyggelse i Odensala socken
There are around 855 000 on-site sewage systems in Sweden and some 1 800 of these are located in the municipality of Sigtuna. The Sigtuna local authority has set the goal that all sewage systems with insufficient function should be improved before the end of year 2010.
A malfunctioning on-site sewage system may cause three main problems: spreading of diseases, discharge of eutrophicating compounds and wastage of resources. The municipality strives to reduce these problems already at the stage of granting permits for installation of on site sanitation systems. The municipality has recently adopted new guidelines, which demands certain minimum reductions for different compounds. The guidelines also state that it is preferred that neighboring house-owners cooperate in jointly built and operated sewage systems and that the system should be able to recycle plant nutrients.
Att mäta eller inte mäta? : En kvalitativ undersökning om prestationsmätningar på en av Blekingesjukhusets kliniker
Blekinge Hospital suffers from a budget shortage of 100 million SEK, while the government now requires that hospitals will no longer be running a deficit. Blekinge Hospital will then use their limited resources to survive in the future and the activity must be enhanced in order to keep costs low without having to lay off personnel. The idea is that the organisation should be more efficient with a more efficient resource usage. Performance measurement systems are important tools for achieving the policies set out within an organization, measuring and evaluating performance is a way to see where improvements in efficiency may be necessary in the business. Balanced Scorecard (BSC) is one of several measuring systems, where the focus is on measuring non-financial performances.

Cooking banana farming system in rural Uganda : a comparison between agroforestry systems and non agroforestry systems
The demand for food, feed, fibre and fuel has increased in Uganda over the past 50 years due to population growth. Recurring extreme climate events such as drought and flooding, in combination with large-scale land degradation, have led to declining crop yields. Lack of equipment, money and socio-economic issues has contributed to low yields. However, the soils in Uganda have the potential to produce much higher yields than they do today.
This study, which was carried out in April-June 2013 in Kkingo District, south-east Uganda, examined the effects of agroforestry on yield of cooking bananas in small-holder farming systems. Six farms practising agroforestry and six farms with no agroforestry, which were chosen in cooperation with the NGO Vi Agroforestry, were compared.
Hinder & möjligheter med dagvattenhantering : Fallstudier över Linköping och Norrköping kommuns arbete med alternativ dagvattenhantering
More frequent and intensified rainfalls are expected to occur due to climate change in the nearfuture. This together with a higher proportion of paved areas increases the pressure on today?sstorm water systems (Risinger, 2014; Boverket, 2013; Stahre, 2006). Traditional storm watersystems (i.e. underground pipe systems) have during last decades started to be questioned(Olshammar & Baresel, 2012).
