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.

Aim is to investigate from a criminological perspective how the safety questionnaire in Älvsborg police district can be improved theoretically and methodologically, in order for the questionnaire to effectively measure criminal victimisation, concern about crime, safety and confidence in the police.1. What should a good questionnaire contain?- Which methodological problems are related to measuring criminal victimisation, concern about crime and confidence in the police?- Which criminological theories are interesting in this context and how can questions be designed from these theories?2. How will the themes now represented in the questionnaire be measured in the best possible way? Are there any reasons to remove, The material consists of questions from the safety questionnaire, the total analysis report and individual reports for the local authorities, as well the results and technical information from Mind Research.

When establishing a groundwater protection area it is of great interest to be able to estimate the transit time of the groundwater from different places of the aquifer to the withdrawal well. These estimates can be uncertain due to heterogeneities in the aquifer. As a part of the work to develop methods for a more certain delineation of protection areas, a tracer test was performed in an esker located 25 kilometres NW of the town Uppsala.The purpose of this master thesis was to perform, describe and evaluate the tracer test. Travel times from the tracer test should then enable comparison against stochastic simulated travel times of the groundwater in the area.Three dyes (rhodamine WT, uranine and naphtionate) and a salt (NaBr) were used in the tracer test. The tracers were injected in four different wells located 25 meters from a pumping well.

Istället för att få standardutseendet på sina D-uppsatser ville en avgångsklass på en Mediedesignutbildning göra en bok där de samlade sina uppsatser. Denna bok fick en ny form som arbetades fram i den här uppsatsen. Huvudfokus låg på läsbarhet och frågor om estetiken i typsnitt och layout samt om det var möjligt att behålla seriositeten samtidigt som den känns kreativ och modern. 18 personer var med i försöksgruppen som bland annat fick rangordna de tre typsnitten Times, Sabon och Verdana för det aktuella ändamålet. Sammantaget var Sabon det typsnitt som visade sig vara mest lämpligt för en publikation av det här slaget.

The milk production has developed rapidly the last years. The milk production per cow is increasing and the production units are larger with an increasing number of animals and a decreasing number of workers. Many milk producers invest in automatic milking systems (AM) to meet this change. In these systems the cows can voluntary decide milking frequency and usually the milking frequency are higher than two times per day. But how does the milking frequency effect the composition of the milk? The aim of the present study was to study the effect of milking frequency on the milk composition and the milk fat quality.

Syftet är att undersöka om Sverigefonder under en nio- sju- respektive femårsperiod genererar riskjusterad över- respektive underavkastning. Målet är därefter att härleda avkastningen till en fondförvaltares förmåga att framkalla en skev fond, alternativt till dennes eventuella selektivitets- respektive timingförmåga. Detta med hjälp av Jensens Alfa, Treynor & Mazuys modell samt Asymmetric Response Model. Ett första delsyfte är att utreda i vilken utsträckning avkastningen kan knytas till det fondbolag som förvaltar fonden respektive fondens förvaltare, antal förvaltarbyten, storlek samt omsättningshastighet. Målet är även att koppla egenskaperna till skevhet, selektivitets- samt timingförmåga.

The study concerns the unloading of pigs at the slaughter house, both from the pigs view and from the transporters view. The study has been carried out at the slaughter house (SLP) in Helsingborg, Sweden. It includes a questionnaire to all transporters (65 % response) and a direct observation of the unloading. The transporters handling of the pigs, their use of different equipment and the response of the pigs has been studied. The pigs behaviour at unloading and their reactions to environmental factors has also been studied.

Sleep is a vital part of life. Even so a lot of the mechanics regarding sleep is unknown. The dairy cattle of today live a stressful life, as their high milk yields forces them to eat large amounts of feed and spend a great portion of the day ruminating. Do they have time to get enough sleep? Which factors affecting the need of sleep in dairy cattle are largely un-known.

The WT1 gene is a complex gene originally known to suppress cancer in kidneys. Studies of WT1 knockout mice have confirmed the important role of WT1 in the pathogenesis of Wilms? tumour, a tumour which counts for 95% of all childhood renal tumours. In that case the WT1 gene acts as a tumour suppressor gene. Subsequent research has shown that the WT1 gene in many other cases acts as an oncogene, e g in leukemia or lung cancer (even though these cancer forms can emerge as a result of many other aetiological factors).

Syftet med denna studie har varit att beskriva och förstå hur ett antal elever och lärare i gymnasieskolan uppfattar lärmiljöns betydelse för främjande av utveckling inom läs- och skrivområdet. Undersökningen belyser självbildens och motivationens betydelse för utvecklingen samt på vilket sätt eleverna är delaktiga vid utformningen av undervisningen vid svårigheter i läsning och skrivning.  Forskningen har en kvalitativ design där information har inhämtats via intervjuer som har genomförts med fem elever och fem lärare i gymnasieskolan.  Resultatet av studien visar att faktorer i lärmiljön har betydelse för utveckling i läs- och skrivområdet. Eleverna önskar att gymnasieskolan bättre lyssnar till deras egna tankar kring hur lärmiljön ska utformas och lärarna önskar sig större kunskaper i området för att kunna möta eleverna.

This thesis examines the USA?s response to the military coup in Myanmar 2021 through a comparative analysis of the two dominant international relations theories: realism and liberalism. The study uses a qualitative text analysis of the US Burma act of 2021 to test the explanatory power of the theories in the formulation of US policy. The results shows that liberal theory has the greater explanatory power, as the US response was systematically motivated by a normative desire to restore democracy in Myanmar. However, some realist tendencies could be observed, especially through exception clauses preserving US national security interest and the mention of China?s support for the military junta in Myanmar.

In this paper I have conducted an analysis to critically examine survey questionnaire forms used in political research to measure trust and distrust. During the first step of the analysis I aimed to identify how the concepts where used in the forms. The second step involved examining if it was possible to relate the questions and items to five theoretical assumptions based on theories of trust (and distrust). The third step was to examine the quality of the forms, in relation to survey and questionnaire designs.The results of the analysis showed that the institutes that conduct the studies tended to use similar questions to measure trust. Some of the forms that where analyzed had very many questions, which could lead to exhaustion for those participating in studies.

Different methods for shelterwood cutting have been used in differ-ent parts of Europe since the middle ages. The use of shelter wood cutting in Norway spruce (Picea abies (L.) Karst.) forests in Sweden met a revival in the early 1990s as an alternative for the dominating clear-cutting system when silvicultural costs increased dramatically for the latter. Shelterwood cutting systems involve some possible problems but also a lot of positive effects. Among the problems are increased risk of wind throw and damage of the remaining shelter trees caused by the cutting operation. Positive effects are for example a valuable growth in the remaining trees and increased biological di-versity. This study is based on a total of 79 trees from 4 different treatments in a spruce shelterwood, cut in 1994, in the middle of Sweden (62,4º N).

When the use of encryption amongst the regular computer user grows morewidespread than ever it makes the life of the IT-forensics experts difficult.Hampering the judicial investigations that otherwise could have lead to convictions.In this report we will treat the subject of crypto analysis with a focus on decrypting files and devices encrypted with the software TrueCrypt. A solution will be presented that can facilitate the future work involving encryption. The application DFEAT that has been developed during the writings of this report is faster than the corresponding software EFDD, and attacks both partitions and bitwise copies of entire harddrives where PKF fails.DFEAT is a lightweight application that is almost 50 times smaller compared to EFDD and 200 times smaller than PKF's portable version..

In offshore oil production FMC Subsea systems use a product called cap. The cap´s mainly task is to protect hubface and seal areas on inboard hub against dirt, corrosion and mechanical damage under installation of a subsea system. A new model of a cap has been designed and analysed using finite element method. The model is called KC3-12 and has a new function, emergency release, which is a backup method for the ROV (remote operated vehicle) to release the cap from the hubface when it is placed under water. The cap KC3-12 was found to fulfil the criteria under the test load pressure, according to ASME VIII, div2.
