Zoonotic respiratory infections and great ape conservation - an emerging challenge

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.

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.

Kraven på ägare till minireningsverk skiljer sig åt mellan olika kommuner

Discharge of inadequately treated waste water containing nutrients such as phosphorus and nitrogen as well as organic matter and bacteria is associated with a risk of eutrophication and contamination. The Swedish government has decided upon several Environmental Quality Objectives aiming to reduce the emissions of nutrients to water bodies.In Sweden, there are between 675 000 to 1 000 000 on-site sewage systems. Recent studies have shown that the function of small sewage treatment plants is in many cases insufficient. To prevent this regular service and supervision by a professional is needed. The focus of this study are small sewage treatment plants which use a technique where mechanical, chemical and/or biological reduction of pollutants is being used in the same facility to reduce nutrients in household wastewater.The aim of the study is to investigate how different municipalities ensure that small sewage treatment plants fulfill the requirements and reduce pollutants as efficient as the manufacturers claim.

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.

Hållbar utveckling- En textanalys av miljöpolicy i lokal och nationell kontext

Sustainable development is a concept that has been interpreted in a multitude of ways in different contexts. This essay argues that the discourse of "ecological modernization" has strongly influenced the way in which the concept of ?sustainability? has been constructed in Swedish environmental policy. This interpretation of the concept of sustainability offers the possibility of combining economic growth with ecological sustainability which stands in contrast to the assumptions of Deep Ecology and Green Theory. The aim of this essay is to explore how the concept of sustainability is being formulated in environmental policy both on a national level and in the city of Malmö.Considering these issues in a specific context, this essay focuses on city planning that is as an important instrument to promote urban sustainability both on national and local levels.

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.

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.

CSR i plast- och kemibranschen

Corporate Social Responsibility (CSR) is a topic that is becoming increasingly important in today's society. CSR is a concept whereby companies voluntarily integrate social and environmental concerns both in their business but also in interaction with their stakeholders. The society of today sets high expectations for how companies take their social responsibilities, especially in industries where the risks to individuals and the environment are high. In this study, we tried to answer the following questions; what kind of responsibility do companies in the plastics and chemicals industry claim to take and why might this be due? What differences exist between the investigated companies in the industry and what may these differences be rooted in? The purpose of this study was to obtain an understanding of the interest in working on sustainability in the plastics and chemicals industry.

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.

Miljöredovisning : En studie kring varför börsnoterade företag som associeras med en betydande miljöpåverkan väljer att redovisa på ett visst sätt

Bakgrund:Miljöredovisningen är ett sätt för företagen att beskriva sitt miljöarbete. Den har fått allt större betydelse för företagen i takt med att miljöfrågorna blivit allt viktigare hos intressenter och allmänheten. Det gäller för företagen att visa att man tar ett miljö- och samhällsansvar för att skapa trovärdighet och förtroende i samhället.  Syfte:                                 Att ge läsaren en bild över hur och varför miljöredovisningen ser ut som den gör och vad företagen, som associeras med betydande miljöpåverkan, väljer att fokusera på i sina miljöredovisningar. Metod:                              En kvalitativ studie som grundar sig i legitimitetsteorin och institutionell teori har utförts. Vi har undersökt litteratur, vetenskapliga artiklar, miljöredovisningar samt fört intervjuer med personer som har behörig kompetens.  Slutsats:                            Studien visar på hur viktig miljöredovisningen är för företagen som associeras med betydande miljöpåverkan.

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.

Ärtrev som substrat för biogasproduktion : En litteraturstudie och rötning i labbskala

Until 2020, 49% of Sweden's use of energy must derive from renewable sources. Greenhouse gases must as well decline with 40% compared to 1990 as a part of Sweden's 16 environmental objectives. Biogas is part of the effort to achieve these objectives, but as the demand for biogas increases, more substrates are needed to meet the demand. The purpose is to investigate the conditions for pea residue as substrate by performing lab-scale mesophilic digestion with different fractions and notch lengths and then to summarize pea residue as a substrate for biogas production. During anaerobic digestion, 1000 ml bottles were used as reactors for digestion.

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.
