Small pieces of plastic, termed ?micro plastic? in the oceans derive mainly from degradation of big plastics such as beach littering, but also from sources of direct emission from e.g. beauty scrubbers and synthetic sand-blasting. These micro plastics are ingested by marine animals ? mistaking them for plankton ? or via prey.

Preservation of cells and tissues by freezing at temperatures below 70°C has led to new possibilities for the storage of germ cells for fertility preservation. During the freezing process problems might occur, the greatest being ice crystallization which can cause membrane destruction and thus cell death. To minimize this risk, solutions that reduce the freezing point can be added to reduce crystallization and increase survival rates. These solutions are called cryoprotectants. The best method for freezing is still not known.The aim of this study was to analyze the effect of various parameters on the survival rate of human semen frozen with liquid nitrogen.

The technological development and increasing popularity for integrated multichannel solutions constitutes both severe opportunities and challenges for todays' and tomorrows' retailers. On the account of consumers leaving traces when using digital channels and the technological development enabling retailers to use this information to create relevant offers, goal-congruity is relevant to apply in the multichannel shopping context. Based upon previous research on goal congruity and channel integration, our main purpose in this study is to increase the understanding for how congruity in an offer increases the intention to redeem the offer. Several studies focus on and contrast the product characteristics hedonic and utilitarian. However, it has been stated that it is crucial that research also examines the difference in target audience, buying situation and as examined in this study: buying decision process.

Sahlgrenska Academyat University of GothenburgDepartment of Internal Medicine and Clinical NutritionAbstractTitle: Oral intake of green tea and its effect on the appearance of UV-induced erythema, erythema solare ? A systematic literature reviewAuthors: Ernita Antoni Mulliqi and Pernilla GustafssonSupervisor: Sofia KlingbergExaminer: Ingrid LarssonProgramme: Dietetics programme, 180/240 ECTSType of paper: Examination paper, 15 hpDate: April 10, 2013Background: UV irradiation of the skin can cause erythema, clinically called erythema solare. The condition can exert pain as well as discomfort and may in the long term lead to negative effects including skin cancer. Green tea contains catechins which are substances with anti-inflammatory effect that may have positive effects on the skin. The intake of green tea is believed to have a protective effect against UV irradiation, since green tea extracts in lotions in previous studies have shown to increase the skin tolerance level against UV irradiation.Objective: To examine the scientific basis and determine whether an oral intake of green tea has a protective effect against UV-induced erythema.Search strategy: Searches in the scientific databases PubMed and Scopus were made to find suitable articles.

The goal of this thesis was to explore how real estate investment companies are affected by a weaker world economy. The reason to investigate this was that in the 90s in Sweden, the housing market crashed in conjunction with the bank collapse. Therefore I have looked at how the commercial real estate companies would be affected if we were to have a double dip recession, because it has been confirmed by Gyourko that commercial real estate market and the housing market tend to react in the same way on new fundamental information. This was examined through a sensitivity analysis, one investigated the effect of falling rent income and the second analysis looked at the effect of higher interest costs. I found that IAS 40 rule about unrealized profits of properties affected the results in a significant matter and therefore decided to include the regulation in my thesis.

Företag på NASDAQ OMXS Small Cap har sedan 2008 omfattats av svensk kod för bolagsstyrning, Koden. Kodens målgrupp är företagen men syftet är att främja investerares och aktieägares intressen. Det är således rimligt att ställa krav på att Kodens regler är av hög kvalité utifrån deras perspektiv. I studien undersöks vilka samband som existerar mellan reglerna i Koden angående styrelsen och Small Cap företagens lönsamhet, mätt som räntabilitet på totalt kapital. Sambanden används sedan för att avgöra om reglerna i Koden är korrekt utformade eller om de behöver modifieras.

The aim of this report is to analyse the logistics of a medium sized restaurant and give an overall solution for improvements on the restaurant's logistics. The restaurant of interest belongs to Laponia Hotel and is located in Arvidsjaur, Sweden. Investments for over 100.000 Euros are planned for the hotel, which includes a reconstruction of the restaurant. The details on how the restaurant will be reconstructed are not yet known. I therefore chose to analyse the problemin general terms and find a solution that is focused on the logistic system itself rather than its layout.

This essay attempts to show a relativistic effect on the representation of motion situations. A summarize and defence for lingusitic relativity as scientifically valid and some taxonomic clarifications is initially presented. The relativistic effect is measured by using the elicitation tool Event Triads, developed at the Max Planck Institute for Psycholinguistics. The tool consists of a set of films displaying various motions. Test-subjects are asked to verbalize a situation in a way they see fit.

Are we able to help younger students to develop their understanding and their use of the capital letter, dot and question mark by giving them intensive teaching on the subject during a short period, and would the effect be long lasting?I decided to investigate this together with young students in second and third grade and at the same time try to see which grade would benefit most.By using an experimental research design I conducted the investigation in a class with children from both grades where the result was compared with two similar control groups. The investigation lasted during five months, while the students were able to show their knowledge in the subject just before and after a two weeks period of intensive teaching and then again after four months.The result showed that the intensive teaching had an effect that lasted over time and that it was the students in second grade that would benefit most. .

Aim: The study aims to investigate the distribution of grades between students in a practical subject and in a theoretical subject.The problem:What is the grade distribution in physical education and mathematics, with respect to gender, socioeconomic background, parental education, ethnicity, and physical activity?Method:To answer the aim of the study a quantitative method was chosen. As the collection method used was questionnaires to 620 students in the 9th grade in Stockholm. Of the 620 questionnaires, 597 questionnaires were used for the static analysis. The method of analysis used cross tables and logistic regression analysis.

Sahlgrenska Academyat University of GothenburgDepartment of Internal Medicine and Clinical NutritionAbstractTitle: Effects of isoflavone supplementation from soybeans on LDL-cholesterol levels in adultAuthors: Malin Blomgren Alegria and Ruut ReivaaraSupervisor: Lena HulthénExaminer: Frode SlindeProgramme: Dietician study programme, 180/240 ECTSType of paper: Examination paper, 15 hpDate: 2013-04-08Background: One of the most common causes of death in Sweden is due to cardiovascular diseases such as heart attack and stroke. Hypercholesterolemia is one of the risk factors for cardiovascular disease. In Asia, hypercholesterolemia is less common than in the Western countries. In Asian countries, soy products are consumed in larger quantities than in the Western world, which has led to implemented research with the intention of examining soy's potential effect on cholesterol levels.Objective: To investigate whether there is scientific evidence that isoflavone supplementation from soy bean may have a lowering effect on LDL-cholesterol.Search strategy: The databases used for the systematic literature search were PubMed, Scopus and Cochrane. Keywords used were cholesterol and 9 versions of this, and isoflavones and 11 versions of that.Selection criteria: RCT articles, on humans, written in English, published from 2011 onwards, that focused on interventions with isoflavones from soybeans and its effect on blood cholesterol, the participants were over 18 years old and the study time was at least 24 weeks.

This report is commissioned by the Water and Sewage Agency in The City of Mariehamn, Åland. The basic aim is to investigate positive or negative effects of a relocation of the sewage pipe from a wastewater treatment plant, Lotsbroverket. The environmental licence of Lotsbroverket is to be revised and The Environmental Appeal Board at Åland?s Government and Administrative Board has made demands that several possible locations in an outer water area should be examined. The present location of the sewage pipe is in Svibyviken, which has been classified as an ?inner water area?.The objective of this work is to study to which extent the nutrient loading from Lotsbroverket influence the environmental conditions in Svibyviken, and to investigate the suitability of different locations of the wastewater pipe from Lotsbroverket.The way a coastal area looks, i.e., its morphometry, determines to a large extent its ecological characteristics.

Title:Pecking-order i små tillverkande företag Level of thesis:Master´s dissertation in banking and auditing Authors:Mathias Klasén and Maria Waderoth Advisor:Joakim Winborg Background:The area of business financing has been well studied during the 1900´s. Many studies and theories are made with big corporations in mind, and the importance of small businesses wasn?t enlightened until the end of the 1900´s. Business financing has created a number of theories, among them Myers pecking-order theory. This theory implies that business managers prefer internal equity in front of debt and external equity.

The aim of this thesis was to answer a number of questions about the environmental consequences of aircraft de-icing. A further aim was to suggest how the environmental consequences due to the release of de-icing fluids can be measured and reduced.The main impact of the aircraft de-icing on the environment is due to the large oxygen demand for the degradation of glycol based de-icing fluids which are released in the environment. The effect of the increase in oxygen demand depends on where the degradation occurs in the ecosystem. In a sensitive ecosystem, the large demand of oxygen could provide an anaerobic environment which would be harmful for many types of organisms.In order to reduce the negative effects of the applied de-icing fluid, there is some type of collection system at every regular airport in Sweden. The methods of collection can be divided into two general groups, hydrological isolation or vacuum sweeper trucks.

Sweden has for years been struggling with high youth unemployment. The problem is also a hot topic of discussion among experts and politicians, often leading to different proposals to solve the problem. The government chose in 2006 to do something about youth unemployment by lowering payroll taxes for employees up to 25 years. But many experts and studies show that the effects failed to materialize.This study will try to find out if the government subsidies have given any effect on the youth unenployment either by new jobs created or by movement in the labor force. I will use a regression model with an dependent, "difference in difference" variable where the change in the number of employed young people are compared to the change in the number of employed in the subsequent age group.The results show that subsidies are not given any positive effect on the youth employment rate in relation to the subsequent age group..
