Kustnära ekosystem som skydd mot naturkatastrofer : en litteraturstudie från ett riskhanteringsperspektiv
Research suggests that society's vulnerability to natural disasters along coasts could increase as a result of climate change, which is likely to lead to elevated sea levels and possibly an increase in the occurance of meteorological phenomena such as storms and tropical cyclones. Following the Indian Ocean tsunami disaster in 2004 and Hurricane Katrina in 2005, both of which received considerable media attention, empirical data has indicated that coastal vegetation might be able to protect and reduce damages to coastal communities during tsunami events and tropical cyclones.The aim of the essay has been to study the function of coastal ecosystems as protection against tsunami waves and storms from a risk management perspective, meaning that I have, through an overview of scientific articles, compiled current research on how coastal ecosystems can attenuate storm surges and tsunami waves, and analysed how this knowledge can be put into practice in coastal communities from a risk management perspective, i.e. if coastal ecosystems are a viable risk reduction measure, are practically applicable, and if so, how they could be applied.There is empirical evidence suggesting that coastal ecosystems, particularly mangroves, can reduce the strength of a tsunami wave, but full scientific consensus on this issue has not yet been reached. With regard to protection against storm surges, there is extensive scientific evidence that coastal vegetation can mitigate damages and reduce the height of a storm surge, although the wave has to traverse several kilometres inland through thick vegetation for the protection to be effective. A synthesis in the form of a figure regarding the many physical factors that influence wave development through coastal ecosystems has been created in an attempt to simplify and explain the phenomenon.The conservation and restoration of coastal ecosystems can be justified from a risk management perspective, but planting new forest belts for the purpose of disaster mitigation is quite unrealistic and can rarely be sustainable, since, for protection to be effective, the forest belt must extend several kilometres inland from the coast, and would thus likely prove difficult to implement along coastal societies..

Studiens främsta målsättning har varit att ta reda på om det förekommer aeroba mikroorganismer på handtagen på kundvagnar och kundkorgar som används i dagligvarubutiker. Förutom detta har undersökningen syftat till att finna svar på frågor som; om det förekommer aeroba mikroorganismer på handtagen vilka typer, familjer och arter tillhör de? Finns skillnader mellan antalet cfu (kolonier) på handtagen på vagnar och korgar? Finns skillnader mellan antalet cfu på handtagen från morgon till kväll samt finns skillnader mellan antalet cfu på handtagen på vagnar mestadels förvarade utomhus och mestadels inomhus? Hur ofta rengörs vagnarna och korgarna och erhålls någon skillnad i antalet cfu mellan en otvättad och en tvättad korg?Undersökningen har gjorts med hjälp av Hygicult TPC slides, vilka är avsedda för snabb kontroll av mikrobiologisk hygien på olika typer av material som ytor och fasta och flytande material. Agarfilmen på plattan är så kallad Total Plate Count Agar och den gynnar snabb tillväxt av de vanligaste förekommande bakterier, jäst- och mögelsvampar.På 103 av 104 tryckplattsidor, kunde tillväxt av mikroorganismer observeras efter inkubering i 32oC i två dygn. Detta visar på att det förekommer aeroba mikroorganismer på handtagen på kundvagnar och kundkorgar som används i dagligvarubutiker.
En ekonomisk utvärdering av framtida biobränslebaserade processkoncept inom energisektorn
The main purpose of this bachelor thesis is to create a product in the form of a database that can be used for cost estimates of equipment within bio refineries. Through interviews and literature searches the key components and their costs were identified. The database was constructed in Microsoft Excel with different tabs for different categories of components; these tabs are further divided into three parts: one part with costs, one part with calculations and an information part. Most of the part with costs contains the expenses found in scientific papers during the literature study, the calculating part converts different capacities according to user preferences and the currency to euro (?) from 2010 and the information part consists of references and information about what is included in the cost.The database is a good tool for making cost estimates for bio refineries.
Ett tidigt möte med matematik : En förskolas arbete med matematik
This research is about the experience educationalists have of children encountering mathematics in a preschool. What is the impact of introducing mathematics in preschool? How do educationalists work with mathematics and how do they experience the children?s interest in mathematics? The aim of this degree project is to examine how educationalists experience children´s interest in mathematics when they encounter mathematics at an early age. The degree project is limited to educationalists and children within a preschool located north of Stockholm.This research seeks answers to the following questions at issue. Does an early encounter with mathematics in preschool lead to increased interest in mathematics among children? How can educationalists in preschool work in a appropriate way with mathematics to stimulate children to develop within mathematics and to increase their interest? How does educationalists in preschool experience children´s interest in mathematics?Theories by Piaget, Vygotskij and Dewey were used as well as former research in this subject.To answer the aim and the questions at issue in this research, three interviews was conducted with educationalists at the preschool and recorded with a Dictaphone.
Teknisk analys : Är det lönsamt att vara trendig?
Trading based on technical analysis has its roots in the U.S. financial industry where it has long been common practice, in Sweden however the trading style has not had the same impact. Based on the results from the preliminary study we believe this is about to change and that the topic therefore requires further studying. Several online stockbrokers today provide information and tools for technical analysis to their clients. As the list of indicators to use for creating strategies is so immense it is interesting for an investor to know what actually could be the basis for a profitable investment strategy.
Rasa åtta kilo på en månad : En kvantitativ studie om hur bantning förekommer på löpsedlarna
Almost half of the population in Sweden suffers from obesity and the cases of eating disorders are increasing. We are exposed daily to the belief that losing weight will make us happier and it will just be through this particular diet. Even if it has been proven that short dieting plans like ?lose 20 pounds in one month? doesn?t give a long-term result, society continues to buy into the idea that they do.Every day 16000 placards are placed around us in Sweden with loud yellow colors and big black letters which make them almost impossible to avoid. Their main purpose is to attract and get as many people as possible to buy single copies.This essay deals with several questions: How diet tips figures on placards and how this has developed through years.
Representation = legala mutor? : Gränsen mellan representation enligt 16 kap. 2 § IL och mutor eller andra otillbörliga belöningar enligt 9 kap. 10 § IL
Companies use different forms of representation to promote business negotiations. The regulations for the right to deduction for the cost of representation are stated in Chapter 16 section 2 of the Swedish Income Tax Act (IL). According to the law there must be an im-mediate connection between the expenditure and the business practice and the claimed de-duction must be reasonable. The Swedish tax authority publishes general recommendations regarding representation which are used as guidelines for the tax payer to follow. The gen-eral provision about tax deduction can be found in Chapter 16 section 1 of the Swedish In-come Tax Act (IL), stating that expenses to acquire or retain income shall be deductible.
"Vi ska inte vara rädd föratt möta människor utanför skolan" : En studie som belyser ett lärarperspektiv på studiebesök i religionskunskap
The project of this thesis is to illuminate the teacher perspective on study visits by examining how six religion teachers relate to the study visit method in high school religious education. The research object of the thesis is to investigate whether teachers believe there are viable didactic possibilities and challenges associated with the study visit concept in education, and to define them if present. The results show that the main didactic advantage, as perceived by the teachers participating in this study, lies in the meeting the study visit enables. A meeting may lead to increased insight and understanding of other people?s way of thinking, conceiving and believing.
Analys av prostaglandin F2? -metabolit i blodet : indikativt för pyometra hos tik?
Pyometra (chronic purulent uterine inflammation) is a common disease in middle-aged and older intact bitches. The disease most frequently occurs in metoestrus and previous research studies have shown that both hormones and bacteria are involved in the development of the disease.
Analysis of the blood levels of prostaglandin metabolite 15-keto-13,14-dihydro-PGF2? (PG-metabolite) has previously been shown to be clinically useful in the differentiation of canine uterine diseases such as pyometra and mucometra. The PG-metabolite concentration has also been correlated to severity in pyometra as determined by hospitalisation length. The purpose of the present study was to investigate if blood levels of PG-metabolite can differentiate uterine diseases such as pyometra from other diseases in female dogs.

Furthermore it also treats the employer's obligation to rehabilitation of employees that has a reduced working ability as consequence of their work. The essay also intends to investigate if there are any differences in the employer?s obligation to work adaptation when recruiting and the employer?s obligation to work adaption for an existing employment. In this work, there is a background chapter which describes the UN and the European Union's approach to work reduction ability and disability. Furthermore, there is a detailed description of the work environment law, the discrimination law, the social insurance code and the employment protection legislation.
BeAKKta : ett kommunikationshjälpmedel som möter behoven av djupare kommunikation hos personer med autism
A vulnerable group in society is people with ASD (autism spectrum disorders) or autism. This group seems to increase, mainly due to genetic factors but also environmental problems. Medical research has accelerated in the U.S. and Europe. The biggest problem for people with disabilities is the inability to communicate, both verbally and socially.
Rabiata rabiesfeminister, orakade gaphalsar och andra aggressiva avarter : En studie av innehåll och argumentation i fyra feministiska bloggar
The purpose of this essay is to study how feminists portray themselves and their opinions about gender issues and other political matters in popular feminist blogs. The blogs that are studied are Lady Dahmer, Fanny Åström, Hanapee and Genusfolket. The overall essay questions are: How does the feminist bloggers present themselves? Which subjects are discussed in the feminist blogs? Which rhetorical devices does the feminist bloggers use? The theories that are used to answer the essay questions are the four spheres where there are inequality between the sexes, theories about third wave feminism, the rhetorical concepts ethos, logos and pathos and the SPADER-model for writing good argumentation. A descriptive method is used to study how the bloggers present themselves, a quantitative content analysis is used to count which subjects the bloggers write about and a qualitative rhetorical text analysis is used to study the rhetorical devices the bloggers use.The result shows that the two bloggers Lady Dahmer and Fanny Åström describe themselves with provocative words while the other blogs have more neutral descriptions.
Tetratermmodellering och regressionsanalyser mellan topografi, tetraterm och tillväxt hos sitkagran och lärk : en studie i norra Island
This study was made in an attempt to give the forest research centre Mógilsá a producedtetratherm map and a better understanding of how topography and temperature influencethe growth of two tree species. The digital tetratherm map model, covering the northernpart of Iceland, was developed to investigate the correlation between tetratherm and thegrowth of Picea sitchensis and Larix (sukaczewii + sibirica). The study confirms theusefulness of digital terrain models in providing data for a lot of different factors and forthe tetratherm model. Hopefully will this tetratherm map be used in future studies.Secondly, investigations were made correlating the growth of the two species againsttopographic factors representing height above sea level, distance to the sea, slope andtopex. Thirdly, investigations were made comparing the aspect and the ground shape tothe growth.The growth rate of Larix had strong significant correlations to the tetratherm and thedistance to the sea- factors.
Ekologi som kommersiell vara
Organic cotton has been in the medias field of vision for quite some time. This interestalso reflects in a growing awareness in the textile industry where more and morecompanies today offer organic cotton in their product range. With this in mind wequestion whether organic cotton has become a viable commercial product. We alsoacknowledge there is a lacking of understanding the complex problems that organiccotton manufacture involves, for example the huge effort and cost required for a transitionfrom conventional to organic cotton farming.The purpose of this paper was to study how textile, ecology and competition today arebeing combined by companies. We wanted with our investigation to find out whethercompanies in the textile industry use ecology as a competitive advantage.
Energianvändning för markkonstruktioner förlagda med ytvärme : En teknisk och ekonomisk utredning av fördelarna med att isolera under värmerören
The need for snow-free surfaces at squares, bus stops, platforms, car parks and sports facilities increases and at the same time energy price rise and the environment is becoming a hotter issue. The construction of the ground heating systems often lack thermal insulation under the heating pipes, which means that the heat from the pipes not only warm up the soil surface but also heats the surrounding soil. The insulation also has more features, by insulating the risk of frost damage is minimized. The goal of this report is to demonstrate the large heat loss and energy costs in the absence of insulation under the heating system.The report begins with a scientific way to study and treating the soil heating system uses, and the theory involved. Furthermore it also deals with different routing principles of heat pipes depending on the facility.All calculations are made with so called finite element method (FEM), in COMSOL Multiphysics 3,5a, where models are created with different conditions.
