Utvärdering av jetomrörning : En studie gällande utvärdering av omrörningssystem vid Ekeby reningsverk

Biogas is a renewable energy produced through anaerobic digestion, which means that organic matter is degraded by microorganisms under anaerobic conditions. The produced biogas can then be used for cogeneration, electricity, heat or upgraded to vehicle gas. Eskilstuna Energy & Environment AB has four digesters at Ekeby water sewage treatment plant, Eskilstuna. One of the biogas reactor (RK4) is equipped with a jet-mixing system while the remaining digester uses top-mixing. The mixing system is an important parameter to achieve optimum operating conditions for the process regarding gas production and degree of digestion.

Kreditbedömning : -en studie om hur banker kontrollerar informationen från fastighetsbolagen

The new accounting standards IFRS and IAS was implemented in January 2005, the purpose was to harmonize accounting standards world wide. As a result of these new rules the real estate companies are allowed to appraise real estates assets at market value. It has long been debated whether this appraisal fulfils the requirements for relevance, reliability and comparability.The paper attends to how banks control the information given by the real estate companies in the process of credit granting. As an introduction we describe the purpose of accounting and the problematic´s about appraisals with market values. Further on there is a discussion on which factors are taken into consideration when banks grant credits.The study is built on interviews at three different commercial banks.

Får är får och get är get : utvärdering av osteologisk metod med stöd av arkeogenetik

The difficullty to distinguish between sheep and goats is a well-known problem in archaeology and osteology. Distinguishing sheep and goats in archaeological animal remains takes time and time is often limited for osteologists. Because of this difficulty osteologists and archaeozoologists often use the term sheep/goat or ?ovicaprids? in their analytical reports. But even if the term sheep/goat comprise both species, this is often not the case when archaeologists and osteologists interpret and present archaeological findings.

The impact of computer programs in safety-critical systems has increased in the past decades and computer-based systems can now be found in a wide range of applications. A new approach for developing dependable systems is documenting all design rationale that affects safety using Intent Specifications. A recent approach for developing complex systems efficiently and in an upgradeable manner is Component-Based System Engineering. In this thesis, these approaches are combined in the development and upgrade of a Remote Robot Control Unit by using the tool SpecTRM. The case study showed that Intent Specifications and CBSE could successfully be combined.

MCNP-modell för beräkning av neutrondos och DPA på reaktortanken vid Ringhals 2

In this report an MCNP (Monte Carlo N-Particle) model is described for the reactor vessel at Ringhals 2. The model is validated against the specific activity in neutron dosimeters, extracted in 1977, 1984 and 1994. The validation showed that the calculations of the model are within the requirements of a maximum of 20 percent uncertainty for every neutron dosimeter except one, extracted after the first cycle. The uncertainty of this cycle was mostly due to the operation data rather than to the MCNP model.The model has been used to investigate various questions concerning radiation damage. The reliability of the traditional measure of radiation damage, fast neutron flux (En > 1MeV) has been evaluated.  This has been done by taking the ratio for this and another measure of radiation damage, DPA (Displacement Per Atom), for various positions and layers.

Kvinnans rättigheter i rätten : Om våldtäktsdefinitionen i svensk sexualbrottslagstiftning

During the past 10 years Sweden has updated its penal code for sexual crimes twice. Despite this few are convicted for the crime of rape in Sweden. As the majority of perpetrators being male, this is a problem concerning women?s rights to respect for their bodies and personal integrity. A possible explanation, and this study?s point of departure is a potential discrepancy between the intention of the law and the interpretation of the same as the Swedish legal system rests on a foundation of legal positivism.
