Computer Modelling of the Influence of Surface Topography on Water Repellency and a Study on Hydrophobic Paper Surfaces with Partly Controlled Roughness
A computer model based on minimization of the free energy, capable to predict contact angles and spreading transitions between Wenzel and Cassie mode for drops placed on surfaces with different topography were implemented in matlab. Simulations were compared with experiments documented in the literature. These showed that reported transitions between Cassie and Wenzel mode can be explained by minimization of the free energy. In this report, a study on the possibility of constructing water repellent paper surfaces with a combination of treatment with octadecyltrichlorosilane and topography changes, is included..
Spannmålsexport & exportsubventioner - hand i hand?
This thesis analyzes the effects of export subsidies on Swedish cereal export. The analyzes are based on data on cereal export from Sweden to countries outside the EU from 1990 to 2003. In 1995 Sweden became a member of the European Union. Before the membership, the Swedish agricultural policy was decoupled in a larger sense than the European CAP was, which means that the Swedish producers had decreased their production more than the European farmers. When Sweden became a member of the EU the production started to increase again to an EU level.
Bärbar - ett hållbart tygkassekoncept
Portable is a project with its starting point in plastic bags, how they negatively affect our planet and how people´s patterns of behavior and qualities of life are affected when people try to live more envi¬ronmentally friendly. Now we have reached the point when peoples way of living and consuming in the western world has to change. This is nothing new and we can now see that sustainability is start¬ing to get attention in every area.Today plastic bags are used on average for 12 minutes. Only one out of 200 is reused, and then only once . This is not sustainable at all.
Nätpiraternas ideologi : En retorisk analys av Piratbyråns webbsite
AbstractPurpose/Aim: To study how Piratbyrån argues for a free distribution of information and culture products and to find a possible ideological explanation for their argumentation.Method/Material: I have used a rhetorical analysis to study and describe Piratbyrån´s website, a website that promotes free distribution of information and culture products. I have done so to find out how Piratbyrån argues for a free distribution and to find out what ideological foundation their argumentation is based on.Main results: The main results of the study show that Piratbyrån uses a variety of rhetorical techniques depending on the subject and purpose of the analyzed text. Their main arguments both promote their own thesis and argue against the copyright industry. The main part of the argumentation is based on logical and factual arguments, but parts of it also rely on an emotional appeal to the reader?s heart in order to persuade.

Further is the second purpose with this paper to find out which decisions that lies behind the design of the management control and how these are in opposition to with the theory..
Avståndsmätning med Hög Noggrannhet till Låg Kostnad
Active sensors are used a lot in the society and industry, for example to gain better control over processes or to get proximity sensing features in different products. Within industry there is great interest in developing safe automation products that can be controlled with high accuracy but still at a low cost.The goal of this project is to develop a prototype of a non-contact rangefinder that measures distance using infrared light. The sensor is to be used for various applications in industries with relatively high accuracy and be compact, but at a low cost. By implementing a rangefinder into a product, more accurate detections of an object?s presence can be done.In this project a new distance sensor, EPC600 from ESPROS, was used.
Utökade tillämpningsmöjligheter för turbinlösning i våtpartiet hos tissuemaskiner : Konceptförslag som möjliggör tillämpning av turbinlösning för maskiner vars banbredd är bredare än 2,9 meter
AbstractThis thesis is the final part of the Innovation and Design Engineering Programme (180 ECTS credits)at the Faculty of Health, Nature and Engineering Science at Karlstad University. The extent of thisthesis is 22.5 ECTS credits and has been performed independently by Hannes Jernberg during thespring of 2013. Metso Paper Karlstad AB is the task maker of this project, and Arvid Johansson is thecompany Representative. Metso Paper Karlstad AB is one of the world leading developer andmanufacturer of tissue paper machines.In the current situation, the company has developed and patented a power management systembased on a Cross Flow Turbine. The current construction is limited to a paper width of 2.9 meters.The company wants to take advantage of all the opportunities provided by the patents, to develop aturbine solution paper machine with a paper width that is wider than 5.5 meters, and give the abilityto manufacture paper for lower energy consumption which is an important part of the production asit is very energy intensive.Problems arise with the increasing length of the turbine, ultimately resulting in that the deflectionbecomes too big and that the momentums, due to the increased torque the turbine blades breaks.By applying the design process, this work has resulted in a number of potential solutions to theproblem.
Lex Sarah : Vad händer sen?
This paper aims to find out what lex Sarah is and how the process looks like when it comes to the investigation, from reporting to registration to the IVO, the inspection of health and social care. Who investigates, the objective of the lex Sarah and how many cases of reports that comes to registration from the year between 2010-2014. Which legal consequences it can be for an employee who has been notified is investigated also. Previous research only deals with freedom of speech, criticism and the complaint goes to the asset, and because of that, this paper focuses on individual cases where employees ' perception of a lex Sarah-registration gives a psychosocial approach. The paper is limited to a municipality where statistics are retrieved and a comparison at a national level is performed.

Rummets betydelse för kunskapsproduktion ? en tolkning av Lunds stadsbiblioteks funktioner i ljuset av dess arkitektur
This paper aims to apply a specific architectural theory onto Lund City Library in order to achieve a better understanding of how the physical concept of the library is affecting our knowledge and our production of meaning; and furthermore how it suggests a certain form of usage. This paper discusses the ways in which architecture is affecting us when we use the library. The paper attempts to answer the following question: ? Which one of Koch?s spatial structures could apply to Lund City Library, and in which ways could this spatial structure be a producer of meaning? The specific architectonical theory used is developed by Daniel Koch in his paper Spatial Systems as Producers of Meaning: the Idea of Knowledge in Three Public Libraries. This theory is the method of the paper as well.
Product Development Processes in the Nordic Paper Packaging Companies : an assessments of complex processes
It is important for firms to continually develop their offerings as the business landscape develops in order to sustain their competitiveness (e.g. Schumpeter, 1934; Ansoff, 1979; Porter, 1985; Trott, 2012). In a context of globalization, rapid technology development and changing customer needs, the paper packaging industry is urged to enhance its product development activities (Hansen & Niskanen, 2007; Björkdahl & Börjesson, 2011). However, there is little research about paper packaging firms? product development processes (ibid).
Katherine Mansfield och Virginia Woolf : Masker och självidentiteter
This paper investigates the relationship between the two modernist writers Katherine Mansfield and Virginia Woolf. The two authors had a frail and complicated friendship that influenced their fiction and fictional characters more than the general public knows. My paper investigates how Woolf can have found her fictional story ideas direct from their friendship. With a comparative theory I?m finding and giving examples of how their friendship is reflected in their fictional stories, and I?m backing up my examples with citations from their own diaries, letters and notebooks.
Pivot - en aktiv sittmöbel för kontorsmiljö
The purpose of this project was to invite a changed perception of active sitting, to introduce a more active way of sitting in office environments and destigmatize an active sitting posture such as straddling by giving active sitting products conscious aesthetics based on environment and positive associations. The goal with this project was an active sitting product for office environments with aesthetics considered encouraging to movement in a relaxed way, regardless of age and gender, and connect to materials and aesthetics related to activity, experience and recreation. Horseback riding, retro style surfing and skateboarding was an entry of investigation. The project was based on existing active sitting products, their function and production techniques. It was not a part of the project to investigate new models of sitting.
Om matematikundervisningens svåra konst. Ett sätt att undervisa abstrakt bevisföring
Tree fiber lengths controls properties like strength and smoothness in paper and other wood products. For forest researchers it is of interest to be able to determine the fiber lengths in standing trees. Mo?rling et al. (2003), among others, have developed methods to estimate fiber length distributions in standing trees without damaging them.
Åttiotalisternas entré på arbetsmarknaden : Rekryterares uppfattning om åttiotalister
AbstractThe topic ?The effects of music in the supermarket on consumer behavior,sales, and customer state of mind? was assessed to try and analyse the emotionaldifferences that may occur as well as the sales variations that may arise fromplaying music in a supermarket. The reason for this study is that grocery storesare very common and abundant in most neighborhoods, as is man?s necessaryconsumption of food. In almost every city grocery stores must compete hardagainst each other in order to succeed in offering the most appealing options toconsumers.
