FAKTORER BAKOM M?GELTILLV?XT P? N??S SLOTT
With climate change, the temperature and relative humidity in Sweden are increasing. The majority of historical environments lack protection against this increase, which also increases the risk of mold infestation in these environments. One of these environments is N??s Slott, in which several rooms have recurring mold growth on objects and furniture. By examining one of the rooms in the castle that is in the risk zone or has mold growth, factors behind the mold growth can be investigated in order to create a basis for future actions against mold.
Undervattensvågbrytare - En modellstudie
Today?s wind power plants are only compensated for their reactive power consumption at no-load. As the wind power plants grow bigger the amount of reactive power they need also increases. This is no longer a problem that can be ignored, especially as the net owners are beginning to charge the reactive power they transport.In this thesis a couple of different methods of compensation and their prices will be discussed and evaluated. Problems, such as self-excitation, that can occur if one fully compensates the wind power plant will also be brought to surface.

Hur skiljer sig investeringsbedömningen mellan kommunala och privata fastighetsbolag?
This dissertation aims to explore how an investment appraisal differs depending on if it is conducted by a municipal or a private real estate company. Municipal and private real estate companies are not performing on totally equal terms in the property market. A municipal company in Sweden has a public service mission. The consequence due to that mission is that they have limited yield potential but on the other hand the right to certain subsidies. They are also limited by the law of public purchasing (in Swedish: Lag om offentlig upphandling) in the investment process.
Fysisk aktivitet hos personer med metabolt syndrom
A quart of the of the adult population worldwide havemetabolic syndrome. A sedentary lifestyle, low physicalactivity, combined with wrong eating habits, stress,smoking and psychosocial factors, are the main causes ofdevelopment of the metabolic syndrome. The purpose ofthe literature review was to illuminate the physicalactivity in persons who have the metabolic syndrome, andwhat sort of advice a nurse use in the promotion ofphysical activity. The study was conducted as a literaturereview, including 15 scientific quantitative articles. In tenarticles, the focus was on physical activity at themetabolic syndrome, and five articles focused on variousforms of counselling for physical activity.
Utveckling av en metod och en utrustning för mätning av bränslesprayers rörelsemängd
A new type of device for measuring thev m& ?rate of fuel sprays from a diesel fuel injector has been developed and the various steps in the development are described. The device works by deflecting all of the sprays from the injector at the same time by using a bell shaped deflector. A load cell consisting of a machined steel part with strain gauges mounted on it measures the resulting force. The shape of the curvature in the deflector bell shape has been evaluated by photographing the flow in a 2D?version of the curve shape.
Studier av utseendet på askan i sodapannor med hjälp av bildanalys
To reduce emissions of carbon dioxide (CO2) Carbon Capture and Storage (CCS) technologieshave been developed. Chemical Looping Combustion (CLC) is a CO2 capture technologywith the CCS framework, and at Chalmers University of Technology in Gothenburg,Sweden, a 100 kW chemical looping combustor has been built.This project aimed to investigate to what degree air can replace helium as the uidizinggas for uid dynamical studies in a CLC cold ow model of the above mentioned 100 kWfacility. Experiments were performed using air and helium separately as uidizing gas andpressure data were obtained, which formed the basis for the comparison. The project alsoaimed to investigate uid dynamics in the uidized bed and study when the risk of sluggingoccuring was greatest. The results were presented in the form of figures and tables dividedinto pressure, concentration and standard deviation of the pressure.The results obtained showed that air as uidizing gas did not create the same uid dynamicsas helium over the entire fuel reactor.
Nordiska Fondbolags riskjusterade avkastning : En jämförelsestudie av fondbolag verkande inom tillväxtmarknader
The purpose of this paper is to examine and analyze past development of mutual funds in large and small mutual fund companies and see if there are any differences between these two segments. Limitations on the number of funds have been made by choosing Nordic mutual fund companies that invest in emerging markets over an 11-year period. The study is made on 66 mutual funds managed by 13 mutual fund companies in which the segment of small fund companies includes seven fund companies with assets under management less than 100 billion SEK and the segment of large mutual fund companies includes six fund companies with assets under management more than 400 billion SEK. In the comparison of the segments the Sharpe ratio has been used to calculate the risk-adjusted return. The study shows small differences of the risk-adjusted return between the segments.
Från disk till rum : Basel II-effekter på kreditrisk och information
This study examines the effects of credit risk and information disclosure in the new bank regulating system Basel II on bank and bank customer. The effects are then discussed in a perspective of the economic man and information asymmetric theories. Furthermore is the Basel II effects on the capital adequacy of Andelsbanken för Åland examined.The approach of the study is qualitative and several interviews with individuals on different levels of the examined bank, Andelsbanken för Åland, have been carried out during the collecting of empirical facts about the effects of the regulating change from the Basel I system to Basel II.The research findings are as follows:Andelsbanken för Åland have increased its capital adequacy ratio from 12,7 percent to 14,4 percent, mostly due to lower risk weights on housing mortgages compared to Basel I. Andelsbanken för Åland have started to use a completely new credit risk and customer assessment system which classifies every customer and gives them a credit rating. The system cause a much heavier information gathering of the customers profile as well as a much better assessment of risk than the previous system, which the bank finds positive.
Anestesipersonalens peri-operativa omvårdnad av överviktiga och obesa barn
Children are a group of patients that require special knowledge from the anesthesia staff, both general and specific. Theoretical knowledge and practical experience is necessary to adequately care for the child as it anatomically, physiologically and mentally may differ from adult patients.A growing problem in the pediatric population is overweight and obesity. From a stagnation in the early 2000s the prevalence of overweight and obesity among children in the world are again increasing.The purpose of this study was to examine peri-operative care of overweight and obese children.Systematic searches were done in PubMed, CINAHL and Scopus. After the quality audit according to SBU, twelve articles were included for analysis.Results suggest that overweight and obese children have a higher risk of respiratory peri-operative complications. The risk of hospital admission after outpatient surgery was also greater in this group as well as higher costs for health care.Overweight and obese children are complex subjects with more frequent peri-operative risk factors than normal-weight children.
A comparison of two certification schemes for dairy cow welfare in relation to resource-based, management-based and animal-based measures
Traditionally risk-based measures have been used to assess animal welfare in legislation and certification schemes. With increased knowledge and research, debate today tends to focus on and advocate the use of animal-based measures. However this is not a panacea for welfare and the most sound conclusion should be that assessment of animal welfare needs both. The aim of this thesis is to identify the points that need to be taken into consideration to find the optimal balance in the use of input and outcome measures according to the aim of the assessment and how these should be applied when designing a certification scheme? To answer this, a comparison of the use of resource-based, management-based and animal-based measures in two certification schemes for dairy cow welfare, Freedom Food (UK) and Svenskt Sigill (SWE), was made.
Debuten av gluten ? Har tidpunkt för glutenintroduktion någon betydelse för risken att utveckla celiaki hos högriskbarn?
AbstractTitle: The debut of gluten ? Does timing of gluten introduction affect the risk ofceliac disease in high-risk children?Author: Sandra Hagwall Frohm and Maria IngmarSupervisor: Frode SlindeExaminer: Mette AxelsenProgramme: Programme in dietetics, 180/240 ECTSType of paper: Bachelor?s thesis in clinical nutrition, 15 hpDate: May 26, 2015Background: Celiac disease is a chronic disease in which the intestinal mucosa is damaged bygluten exposure, and the only treatment is a lifelong gluten-free diet. The disease affects about1 % of the population worldwide, but the majority are undiagnosed. Ingestion of gluten and thegenotype HLA-DQ2/8 are required for disease development, although additional genetic andenvironmental factors are believed to be of importance. One hypothesis is that timing of glutenintroduction in infants affects the disease risk.
En undersökning av VaR-modeller med Kupiecs Backtest
SAMMANDRAGHistorisk Simulation, Delta-Normal och RiskMetrics prestation utvärderas med hjälp av Kupiecs Backtest. Value at Risk (VaR) beräknas med tre olika konfidensnivåer utifrån Affärsvärldens Generalindex och HSBC kopparindex. Utifrån överträdelser från verkligt utfall undersöks vilken VaR-modell som estimerar marknadsrisken bäst. VaR-modellernas prestation jämförs, och i analysen utreds hur konfidensnivå och tillgångars egenskaper påverkar VaR-modellernas prestation. Resultaten visar att Historisk Simulation presterar bättre än Delta-Normal och RiskMetrics på den högsta konfidensnivån vilket troligtvis beror på att RiskMetrics och Delta-Normal antar normalfördelning.
Brottslighet, psykosocial belastning i barndomen och risk för våld : Könsskillnader hos rättspsykiatriska patienter
Rättspsykiatriska patienter är en grupp med mycket psykosocial belastning i barndomen och mer forskning behövs kring bland annat huruvida det finns samband mellan denna psykosociala belastning, framtida brottslighet och bedömd risk för våld. Denna studies syfte var att jämföra brottslighet, psykosocial belastning i barndomen samt initiala riskbedömningar gjorda med HCR-20 på kvinnor respektive män vårdade vid Rättspsykiatriska Regionkliniken i Sundsvall. Vidare undersöktes ifall förekomst av psykosocial belastning i barndomen korrelerade med bedömd risk för våld bedömd med HCR-20 eller med brottslighet hos patienterna. Studiens sampel bestod av 10 kvinnor och 39 män varav majoriteten vårdades enligt LRV. Data samlades in från journaler, rättspsykiatriska undersökningar och domar samt genom enskilda intervjuer.
Djurskyddsinspektörer : - Behovet av kunskap om exotiska djur
Psittacines and reptiles are exotic animals that are difficult to care for and it requires extra knowledge to make a correct assessment of their wellbeing. An animal welfare inspector, with an education in general animal welfare, may not have a deep enough knowledge of exotic animals to do a proper assessment of the animal?s general condition and its environment. In this paper it was therefore examined if animal welfare inspectors have enough knowledge to do a satisfying inspection of establishments working with selling of exotic animals. A literature study was used to examine difficulties with each species.
