This report will give the reader a description of principles how to measure the
abrasive mass flow in a waterjet cutting system.
The work began with a visit to Water Jet Sweden AB to get a closer look at the
problem. When the analysis of the problem was done the criteria were defined in
the form of demands and desires. The main task of the criteria was to guide the
search for the solution. The work proceeded with an extensive search for
abrasive flow meters along with obtaining information about flow measurement in
general. When the search for abrasive flow meters resulted in nothing all the
efforts were concentrated on finding a principle of measurement that could cope
with the criteria.
Modellbaserad temperaturregleringav partikelfiltrets regenereringsprocess
Due to increasing regulations regarding new diesel vehicles particulate matteremissions the new Scania truck, Scania Euro 6, has been equipped with a particulatefilter. This component effectively stores the particles in the exhaust gas but must becleaned in order to prevent itself from clogging. The filter is cleaned through aprocess named regeneration which is a thermodynamic process in which thetemperature of the filter is raised through fuel supplied to the exhaust gas.The purpose of this thesis is to contribute to the development of improved controlstrategies of the temperature during the regeneration process through thedevelopment of model-based controllers. These controllers are designed in order tohave good performance in stationary as well as automatic regeneration.In order to develop these model-based controllers a model of the system isconstructed. The model is described as a linear thermodynamic grey-box model withflow varying parameters, showing good results in validation.The model provides a simulation environment during the controller design, which isfocused around the development of linear regulators with the exhaust gas mass flowas a scheduling variable whose size determines controllers? mode of operation.
Juridiska processer som marknadsföringsinstrument: En fallstudie kring utformningen av massmedial kommunikation i två EG-rättsprocesser
In public relations and marketing, lawsuits traditionally connote crisis. The purpose of this study is to explore the design and critical considerations concerning risks and opportunities when companies voluntarily initiate lawsuits with the partial aim to get publicity in the mass media. In the following paper, the communicative aspects of two such Swedish cases in the European Court of Justice are studied?a large corporation challenging the Swedish monopoly on gambling and a small company challenging the government on their restrictions for individuals to import alcoholic beverages. The case studies have been conducted through interviews, analysis of legal acts and press articles.
Bioactive peptides in long-time ripened open texture semi-hard cheese
Bovine milk is an excellent source of bioactive peptides. The bioactive peptides are in an inactive state in the protein and are released during enzymatic activity, e.g. during cheese ripening. Specific properties of bioactive peptides from ripened cheese has been reported, e.g. antihypertensive, antioxidative, antimicrobial, immunomodulatory and mineral binding.
?Det här var dagen då anonyma tonåringar via sociala medier startade ett upplopp i Göteborg? En studie över gestaltningen i fyra svenska tidningar av gatuoroligheterna vid ?Instagram-händelserna? i Göteborg år 2012.
On subsequent days, the 18th and 19th of December 2012, large groups of young people gathered to protest in the centre of Gothenburg. The gatherings mainly occurred outside two high schools: Plusgymnasiet and Framtidsgymnasiet. The reason behind the gathering has often been explained by the young people?s reaction to an Instagram account, on which offensive pictures and comments of and about young boys and girls had been published. As a reaction to the protest, police force including helicopters and mounted police, was sent to the streets.
Låta maten tysta mun : Skillnader och samband i graden av mindful eating i förhållande till Body Mass Index och demografiska variabler
Bakgrund: En ökad medveten närvaro kring måltiden och ätandet genom mindful eating har i ny forskning visat sig vara en effektiv metod för att minska en rad olika sjukdomar och hälsorelaterade problem samt bidra till gynnsamma hälsoeffekter. Trots detta finns få studier genomförda i en svensk kontext.Syfte: Undersöka och beskriva graden av mindful eating hos en grupp individer på sociala medier i förhållande till Body Mass Index och demografiska variabler.Metod: Deskriptiv tvärsnittsstudie med en kvantitativ ansats. Ett tidigare utvecklat instrument, Mindful Eating Questionnaire (MEQ), översattes och distribuerades som en webbaserad enkätundersökning. Respondenterna rekryterades under en veckas tid genom ett snöbollsurval på det sociala nätverket Facebook. Inklusionskriterierna var att deltagarna skulle behärska det svenska språket, vara mellan 20-65 år och användare av Facebook.
?Regeringen skyndar p? ?tg?rder mot g?ngkriminaliteten - En kritisk diskursanalys om hur media framst?ller f?rebyggande ?tg?rder mot g?ngkriminalitet
Gang crime has increased significantly in Sweden over the past decade, deadly shootings are
becoming more common. This led to the year 2022 being established as the deadliest year in
Swedish crime statistics since the police began compiling national statistics on shootings. Gang
crime is, therefore, a highly relevant topic in the Swedish mass media. Besides the mass media,
the phenomenon is also of interest to politicians and the general public. Because of the
escalation of violence in Sweden, daily reports discuss the measures that should be implemented
to combat gang crime.
D-vitaminsupplementering och dess effekt på kroppssammansättning hos överviktiga och obesa ? en systematisk översiktsartikel
Sahlgrenska Academyat University of GothenburgDepartment of Internal Medicine and Clinical NutritionAbstractTitle: Vitamin D supplementation and its effect on body composition in the overweightand obese ? a systematic reviewAuthor: Johanna Blum and Emma Sellin FrimodigSupervisor: Sofia KlingbergExaminer: Ingrid LarssonProgramme: Dietician study programme, 180/240 ECTSType of paper: Examination paper, 15 hpDate: April 10, 2013Background: There is an increasing burden of overweight and obesity worldwide. Theconditions lead to morbidity and lowered quality of life. Since there is research showing aconnection between obesity and low levels of serum 25(OH)D, this raises the question ifsupplementation of vitamin D may have positive effects on body weight, waist circumference andbody composition in the overweight and obese.Objective: To investigate if there is enough scientific evidence to recommend vitamin Dsupplementation combined with nutrition therapy to overweight and obese patients.Search strategy: The systematic collection of data was performed in the databases PubMed andScopus. Search terms included were ?vitamin D supplementation?, ?obesity? ?cohort?, ?vitamin D?,?vitamin D3 supplementation? and ?overweight?.Selection criteria: Human studies with RCT, CCT or cohort design written in English orSwedish were included.
Akustisk mätning av U-värde
This pre-study investigates the possibility of U-value measurements through an acoustic method. A hypothesis about an acoustic model built on acoustic theories combined with U-value theories is presented to answer the questions:
? Can U-value theory be combined with acoustic theories?
? Can the coefficient of heat be affirmed trough an acoustic measurement?
The idea for this dissertation begun with a logical idea in mathematical similarity, between the coefficient of heat transmission units and sound intensity units.
The U-value theory is based on assumptions such as initial resistance for inner walls and initial resistance for outer walls. The resistance in the material is interpreted through sound intensity theory.
The argument is built upon mass law theory, which means if the frequency or thickness of the material layer doubles it implies an increase of sound reduction by 6 dB.

A remote control can be used to start and stop the robot. The robot is constructed ofmainly steel with smaller, more detailed, parts in plastic. A significant amout of time has beenused to enable the robot to balance on its own.
Utvärdering av två hullbedömningssystem för katt av en djursjukskötarstudent och djurägare
Obesity is a growing global health problem among both humans and cats with the risk of several medical conditions as a result. This can be detected and prevented by body condition assessment methods in order to visualize and detect possible or potential weight problems in cats.To achieve the best results, owner and cat should be introduced to this as soon as possible in their contact with veterinary care.Purina Body Condition System and Walthams Feline Body Mass Index are both morphometric assessment methods that are quick, relatively cheap and simple to perform. 20 cats with owners and a veterinary nurse student participated in a study to compare pet owners and a veterinary nurse student's assessment of the Purina Body Condition System and WALTHAM's Feline Body Mass Index. The body condition assessment methods were compared with each other, and it was investigated which method was preferred, the body condition distribution among the studied cats and if long-haired cats' body condition was more often misjudged. Results of the study showed a significant difference between pet owners and the veterinary nurse student's assessment of Purina BCS with a difference in median of 1.
Näringsbelastning på en anlagd våtmark från åker, skog och enskilda avlopp :
This work is a part of the project ?Våtmarker i odlingslandskapet ? uppföljning av miljömålen? (Wetlands in arable land ? following-up of the environmental goals). The main objective with this project is to study nitrogen and phosphorus retention in a constructed wetland by using mass balance calculations. Continuous measurements of nutrients and water flow through the inlet and the outlet of the wetland are made. However, substantial amounts of nitrogen and phosphorus were assumed to reach the wetland with a drain-pipe transporting wastewater from nearby houses (10 persons).
V?lf?rdens villkor : En WPR-analys av Tid?avtalet
Efter riksdagsvalet 2022 ingick Moderaterna, Kristdemokraterna, Liberalerna och Sverigedemokraterna ett politiskt samarbetsavtal, det s? kallade Tid?avtalet. Avtalet representerar en politisk kurs?ndring i svensk v?lf?rdspolitik, d?r fr?gor om kriminalitet, migration och effektivisering av v?lf?rden ges en central plats. Syftet med denna studie ?r att analysera hur socialt arbete och v?lf?rd representeras i Tid?avtalet och vilka implikationer dessa representationer har f?r socionomers professionella roll och social arbetares yrkesetik.
Vem vinner? Populär och litterär gestaltning i medierapporteringen om Nobelpriset i litteratur
Who will win? Popular and literary framing in media coverage of Nobel Prize in Literature by Magnus Wennerberg Autumn 2013Instructor Mats Ekström The question at issue in this essay is how does mass media frame Nobel Prize in Literature? The starting point is to study whether game framing is occuring in media coverage of Nobel Prize in Literature. Previously, game framing has been studied in coverage of politcs, contrasted against issue framing. Game framing means that media frame politics as a game, a contest between politicians about power. This kind of framing is supposed to be used by media in purpose of attracting larger audience.
