Tubular polyethylene biogas digesters : development and testing of a biogas technology in Malawi to reduce deforestation and support climate change mitigation and adaptation

The aim of the study was to install a biogas system consisting of three tubular polyethylene biogas digesters at a rural household in Malawi and to evaluate the constructed biogas system with regards to relevant system parameters. The purpose was to evaluate if the technology is a possible solution to reduce deforestation and support Malawi in climate change mitigation and adaptation. The study was carried out in the southern part of Malawi in cooperation with the University of Malawi. Locally available materials were used to construct and install the system. Three different feed materials, cow, goat and a mix of cow and goat manure, were used in order to determine which one was best suited to utilise as a digester substrate. After the installation, measurements of temperature, pH, biogas production, biogas composition and system functionality were made. The results of the study show that a biogas system with tubular polyethylene biogas digesters can be successfully installed at a rural household and that the most suitable feed material is a mix of cow and goat manure.

Påverkan mellan ekonomistyrningen och inköpsfunktionen : En studie av Sandvik och Scania

AbstractTitle:The Impact of Management Control Systems on the Purchaser Function - A study of Scania and Sandvik Authors: Mohammad Reza Akhbari and Johanna Sullivan Svensson Published: 2011 Keywords: Management control, purchasing function, impact, control, control instruments, Key Performance Indicators, measurement, communication and organizational structure. Background and problem formulation: In order for a company?s business idea or vision to be fulfilled, the management of a company needs assistance from various means to intentionally affect the operation in the desired direction. Management control concerns activities of both financial and non-financial character in order to implement the strategy of a company and to reach profitability. Since the purchaser function is responsible of spending 50 percent of a company?s total revenue, the function has an optimal starting point to be a key actor in the shaping and execution of a company?s strategic plan.

Är ökad pressfrihet dåliga nyheter för korruption? - En kvantitativ dataanalys som testar styrkan i sambandet mellan pressfrihet och korruption.

This paper aims to broaden the discussion on how press freedom can be a powerful tool in the war on corruption. Previous studies have shown a significant relationship between more press freedom and less corruption, it also shows that the causal link runs from press freedom to corruption and not the other way around. There are quite a few studies on the impact of a free press on corruption and therefore there is a lot more to be published on this issue.This paper looks at press freedom as one of the most important parts of a democratic society and that it plays a vital role in reducing corruption as both an informant on key issues and also as a ?watchdog? on society. But press freedom cannot be seen as an ?easy fix? in a country or the international community's struggle to reduce corruption.

Miljöbedömning av mark- och vattenresurser i kommunal översiktsplanering : en fallstudie av en del av planprocessen i Tierps kommun

This paper describes the integration of environmental assessment in Swedish municipality comprehensive planning through a chosen case study. The implementation of a new EGdirective in Swedish law, concerning Assessment of the effects of certain plans and programmes on the environment, should lead to some changes in the way Swedish municipalities' deals with environmental issues in their comprehensive plans. This could later on lead to new preconditions for municipality comprehensive planning. The purpose of this study was to investigate how the planning organisation in the municipality adapts to new regulations for impact assessment of comprehensive plans required by the Planning and Building act. Secondly the purpose was to partly participate in the early stages of the planning process and thereby indicate and identify possible environmental impacts regarding the aspects of land and water. This was done as a case study in a well defined part of the process.

En jämförelse mellan betongarmeringsverktygen i TEKLA Structures och ADT

Vid uppritandet av byggmodeller på WSP Group i Norrköping använder man idag två program: TEKLA Structures och AutoCAD Architecture. En av anledningarna till detta är att armeringsverktyget Impact Reinforcement i AutoCAD Architecture fungerar bättre än armeringsverktygen i TEKLA Structures. Då man behöver armering i en TEKLA Structures modell exporteras denna till AutoCAD Architecture där armeringsjärnen sedan ritas in. Jag har därför undersökt skillnaderna mellan de båda programmens armeringsverktyg, resultatet är att Impact Reinforcement är lättare att använda medan TEKLA Structures tar längre tid att lära sig, men skulle kunna göra arbetet effektivare med rätt kunskaper..

Uppfatta och reagera : En kvalitativ studie om IT-relaterade resursers roll i kundkännedomsprocesser och kundresponskapacitet

The structures of organizations have gone through a dramatic change over the last years; as a result customer service is no longer a small side activity but a critical part in customer relationship management. Development in information technology has created opportunities as well as challenges for organizations when it comes to providing a customer service with capacity of sensing and responding to customers' needs. Previous research shows a relationship between customer response capability and customer knowledge processeses, this study investigates and confirms this relationship. However, findings show that dedication and understanding for customers needs has a direct impact on both customer response capability and customer knowledge processeses, this result indicates that customer knowledge processes and customer relationship management are difficult to differentiate. Furthermore, this study explores IT-related resources impact on customer response capability and customer knowledge processes.

Epiphytic lichens associated with different traffic intensities along the highway E4

Inventories of epiphytic lichens on Scots pine (Pinus sylvestris) were conducted at three sites in east central Sweden: along the newly build motorway (Road E4), along the old road (Road 600) and in a reference site, to compare the effects of traffic pollution on lichen diversities. At each site, species richness, lichen mean sensitivity value (MK), air quality index of the forest stand/sample plot (LKI) and nitrogen impact value (N) were calculated and it was tested if there was any difference between the sites. Twenty-four species were observed in total, and Parmeliopsis ambigua and Hypogymnia physodes were the most common species at all sites. At Road E4, fewer lichen species were observed than at the other sites and this might be due to the impact of air pollution. The species richness at Road 600 was similar to that of the reference site, which might be explained by the improved air quality.

Genomisk selektion och uppbyggnaden av avelsprogram hos mjölkkor

During the last decade a new technique in animal breeding has developed called genomic selection. It is based on estimations of the effect from genetic markers on traits that are calculated in a reference population. By genotyping individuals, genomic breeding values can then be estimated without phenotypic observations. The aim of this essay is to investigate the response of genomic selection on breeding schemes for dairy cattle. The accuracy of the genomic breeding values is affected by the proportion of observations included in the validation set and how often the equation for estimating breeding values is reevaluated.

Har en goodwillnedskrivning någon effekt på aktieavkastningen? : En eventstudie av bolagen på Stockholmsbörsen

On 1 January 2005, IFRS (International Financial Reporting Standards)was mandatory for all listed companies within the European Union. The introduction is to create a transparent and consistent reporting. Mainly to provide companies, investors and financiers the same access to world capital markets. Since the introduction of IFRS, the goodwill value is determined by annual impairment tests. If an impairment of goodwill is a fact the goodwill decreases in value.

DFM för Lasersvetsning

 The purpose with this thesis was to develop a designguideline which will simplify the development of new products that will be laser welded. The need for this thesis has come forward from the quality problems that Volvo Construction Equipment, Components Division is having with their laser welding manufacturing unit. The reason for the problems emerges from the bad communication between the development unit and the manufacturing unit within the company when the products produced today was developed. This resulted in products that were hard to and in some cases almost impossible to weld. To avoid these problems from occurring again it was needed to gather the experiences within this area and compile it and present in a brief a pedagogical manner. The information for the groundwork of our results has been gathered by interviews of several key persons in Volvo Construction Equipment, Components Division.
