Affärsänglar är inget nytt fenomen på dagens globala marknad. Enda sedan Columbus tid har affärsänglar investerat kapital i företag och stöttat nya idéer. Idag har begreppet affärsänglar fått en mer framträdande roll i vårt alltmer komplexa samhälle, vilket tyder på att politiker och företagare har fått en större förståelse för affärsänglarnas betydelse för företagstillväxt och företagsutveckling. Affärsänglarnas verksamhet är emellertid fortfarande relativt outforskat. Affärsänglar definieras som privatpersoner vilka investerar eget kapital i form av kunskap och pengar i företag genom ett aktivt eller passivt deltagande.

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.

The position of middle-management is a role where the manager is at risk of being caught between its management and its employees. Elderly care is an industry that has been discussed a lot, to a large extent on how businesses should be managed and by whom it should be conducted. Middle-management in the business of elderly care thereby possess a vulnerable position in a controversial industry. In this study the aim is to investigate the managers' roles and tasks in both the public sector and the private sector in elderly care. It also aims to examine whether there are differences between the roles and how they in such cases is manifested.

Upplevelserummet blir alltmer viktigare. Tidigare undersökningar om upplevelserummet har enbart fokuserats på de fysiska faktorerna. Men vad som även behöver undersökas är vilka faktorer utöver de fysiska som kan påverka en människas uppfattning om upplevelserummet och beteendet. Vårt syfte är att undersöka vilka faktorer som främst påverkar samt hur dessa påverkar kundens kvalitetsuppfattning av upplevelserummet..

The aim with my study is to highlight, illuminate and examine the social and maternal health care motivational work of pregnant women with a risk or abuse of alcohol and / or drugs, and what actions can be considered for these women. In addition, the aim is to explore how social services and maternity care might interact in this type of case. The aim is to convey the subjective experience of each of the interviewees. For the purposes of this study, I have chosen to use the qualitative research method. I have interviewed social workers in individual and family care, and midwives.

The conservation of great apes faces many challenges, one of which is the threat of infectious disease outbreaks. Zoonotic transmission of respiratory diseases from humans to wild great apes has recently been confirmed. Since respiratory disease is one of the major causes of death in both gorillas and chimpanzees, this gives reason for major concern. Little is known about the risks of disease transmission from humans to great apes in natural environments, and there is a need for systematic risk evaluation. Researchers, conservation staff and tourists spend time in very close proximity of wild great apes, sometimes during long time periods, which poses a potential risk of disease spillover. However, the presence of researchers and tourists has been shown to decrease the risk of poaching, making the matter increasingly complex.

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.

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.

Purpose: When the Deepwater Horizon oilrig in the Gulf of Mexico faced disaster in late April 2010, news coverage immediately began of the disaster that would unfold. BP took the blame and its financial resources were strained as it struggled with stopping the oil leak, cleanup work as well as its PR image. While the US took many blows of the consequences to ecosystem and tourism, financial consequences swept across the world, mainly Britain, where BP had its headquarters.The event gives an excellent chance at comparing the media coverage from both the US and Britain. By studying The Daily Telegraph and The New York Times, we want to see both similarities and differences in the themes they focused on as well as seeing trends in the themes over time.Theories: The theory chapter is heavily based around the Agenda-setting theory in the media communication field.Methodology: A quantitative content analysis (QCA) of some 500 news articles in The Daily Telegraph and The New York Times from April 22 to July 15. The QCA was made to find the main theme of articles to give us data on how many articles of each theme, as well as their distribution over time.

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.

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.

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.

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.
