The freshwater pearl mussel (Margaritifera margaritifera) is a large freshwater mussel. Because of its sensitivity to human impact, such as eutrophication, acidification and alterations of hydromorphology, the species is considered as a robust indicator of stream water quality and biodiversity. Moreover, due to the species complex life cycle, including a larval stage on the gills of salmon and trout, and sensitivity of early life stages, regeneration is often used as an indicator. The freshwater pearl mussel is also used in the expert judgement of status classification of benthic invertebrates according to the European Water Framework Directive. The purpose of this study was to gain a deeper understanding of the freshwater pearl mussel as an indicator for Swedish streams. It was made with two types of association analyses.

Virtualization has increasingly been adopted in the last decade and the usages of virtualized environments are going to be an important part of how computers are used in the nearby future. There are a lot of advantages with virtualization and different methods have been developed to make it as efficient as possible.Forsmarks Kraftgrupp were interested in the possibility of taking advantage of virtualization in their testing environment.In this report, hypervisors of type 1 and type 2 and containers have been evaluated to determine which method and what program is preferable on a server cluster of four HP ProLiant DL380 Generation 4. Because of the hardware specifications of the DL380, focus has been on virtualization programs that do not require hardware assisted virtualization.The results show that it is possible to use some of the type 2 hypervisors on the HP ProLiant DL380 Generation 4. The suggested virtualization programs are VMware Workstation or Oracle VirtualBox. .

ABSTRACTThe discussions about energy use have increased year by year everywhere in the society, and so also in the healthcare sector. But what is actually energy use in a hospital facility, and what affects it?The typical way today to express the energy use is in kWh/m2. The problem with a key performance indicator that is expressed as energy use in relation to a specific area is that it does not take into account the activity in the building. Even though the activity to a very high extent affects the energy use.

Hazel (Corylus avellana L.) is a common feature of meadows and pastures where it can grow in large populations and become very old. Is it possible to use the size of hazel stools for age determination and is it possible to use the size distribution of a population to provide information about how the land has been used? Hazel populations on ground where the lake-water level had been lowered, has been studied to validate an already developed growth model of hazel clones. Different hazel populations, on wooded meadows affected by mowing or grazing or overgrown meadows, were studied to evaluate the method utilizing hazel as land use indicator. The growth model was used to compare the size distributions of hazel populations with historical periods, which has been important for changes in agriculture or demography.

Earlier investigations showed that damages on timber from feeding rolls could be within the lower classes of damage according to VMRs classes. Knowledge about differences in productivity between kind types and aggressive types of feeding rolls is necessary because it should influence the question about damages on timber caused by different feeding rolls. In this study the production and timber damage in a harvesting head were evaluated at three levels of pressure (8, 10 and 14 MPa) on the feeding rolls, and with three different types of rolls. One type, the rubber cushioned steel plate roller had 10 mm studs and rubber damping, one ?middle? type made of solid steel with 14 mm studs, and one aggressive type, also made of solid steel with 18 mm studs.

Today there are many different Cad-applications on the market for engineers. Because of big building projects it has become more and more important to work with the same application or to have access to a neutral file type to be able to transfer files between different ones.This report studies the single objects and how they react when transferring them between ADT and ArchiCAD via the neutral type IFC. We have also been looking at problems during the transfer between and if there are some connections between these problems. Afterwards we created a neutral object model of a small country house to see if the objects appeared different. The result shows no differences.But looking at the problems that appeared during the transmissions they felt small and no logical.Today it is not possible to save in a neutral type without facing small problems.

In order to decrease the disturbance from a cable testing equipment, the company Ericsson Network Technologies in Falun determined to design a new series resonant test system with a lower frequency. The new equipment is of series resonant type with a system frequency of 500 Hz. This equipment consists of an inductor, a capacitor and a voltage source. The voltage source is the same as the old one, the cable acts as the capacitor but the inductor has to be designed especially for the new equipment. In this thesis work several air coil inductor types were examined.

Background: Effective treatment of patients with type 2 diabetes needs a good communication between nurse and patient. This creats a good relation and leads to a more effective patient education. Aim: The aim with the literature study was to describe how nurses trough patient education can achieve self-care for patients with diabetes type 2. Methods: Literature studies with both qualitative and quantitative articles were examined. Findings: The articles that were chosen for the results were sorted in the two categories relation and communication.

There is convincing research which shows that the enzyme alkaline phosphatase (ALP) has a central role in the mineralization of bone, more precisely that its catalytic activity is needed in the process. ALP is found on the surface of matrix vesicles where the mineral is formed. One theory about the function of the enzyme is that it binds to fibrous collagen in the bone and thereby incorporating the mineral into the bone. The purpose of this study is to establish whether ALP binds to collagen. If this is the case, more elaborate studies around this will be performed.

This thesis aims to answer the following questions: What type of vocabulary is used in the humanities? What does this implicate when it comes to indexing in the humanities? How do humanities scholars seek information and what type of information do they need? What consequences does this have when it comes to the development of humanities databases? How is the MLA International Bibliography organized? How does its indexing system ? CIFT ? work? How does the MLA International Bibliography correspond with the needs of the humanities scholar? The study shows that the type of vocabulary used in the humanities differs significantly from that used in the sciences. Therefore, information retrieval is often said to be problematic in the humanities when compared to the sciences. This is, however, not completely true. If consideration is taken to the different type of vocabulary used in the humanities, subject access proves to be more straightforward than has been generally recognized.

Financial bubbles are characterized by a large increase in the economic growth on the market as a whole or in specific industries. The change gives rise to an increase in the capital needed to finance this growth. Companies typically have a choice between equity and debt capital to finance its business and the mix of these types of capital is often referred to as the company?s capital structure. There has been a lot of research done in the field of financial bubbles and ofcapital structure, as of yet no studies seem to address these two areas in combination.The aim of this study is to examine if financial bubbles affect a company?s capital structure and through this also examine if the supposed changes in capital structure can be generalized.The study comprise of two identical time-series which examines the changes in leverage and the choice of financing during the Swedish real estate bubble in the early nineties and the IT-crash at the end of the 2000th century.

Background: Type 2 diabetes is a disease which causes vascular damage, stroke and premature death.Oxidative stress may play a role in the development of insulin resistance and diabetes. Selenium is amineral involved in the protection against oxidative stress, and has been thought to be favorable in theprevention of the disease. However, this has changed since trials observed positive correlationsbetween high selenium levels and incidence of type 2 diabetes.Objective: To examine the studies that investigates seleniums effect on the incidence of typ 2 diabetesSearch strategy: Searches have been done in PubMed and Scopus.Selection criteria: Included studies were human studies in English/Swedish with RCT or cohortdesign with the aim to investigate the correlation between selenium and incidence of type 2 diabetes.Excluded studies were studies whose aim was to investigate the role of selenium in patients withexisting diabetes. Studies regarding pregnant women, animals or children and with in vitro design werealso excluded. Of the studies found in Scopus where MeSH terms were available, the ones who did notinclude relevant terms were excluded.Data collection and analysis: Studies were collected according to the aforementioned criteria.
