Tillverkning av mikronålar för medicinsk tillämpning

Transdermal drug delivery, besides painfulinjections with syringes, has long been associatedwith small size particle pharmaceuticals, which candiffuse through the skin. This method of drugadministration has only been applicable on a smallnumber of drugs, where active molecules are smalland delivery time should or can be long.Other drug delivery options are oral administrationand injection with hypodermic needles (ordinaryhospital syringes). In oral administration thestomach and liver tend to dissolve the drug and theeffect becomes more difficult to anticipate, anddrug delivery rates difficult to control. Hypodermicneedles are used as a mean of drug injectiondirectly into the bloodstream. This method ispainful and risks infection due to tissue damageand skin penetration.One way to get a painless non-damaging techniquewith high delivery rate that still can delivery largemolecules is to manufacture an array of microscopichollow needles and equip them with a pumping unitthat delivers the correct amount of drugs.This thesis shows the technique and possibility ofmanufacture micromachined needles using low costtechniques of Ion Track Technology (radiation ofheavy ions creates porous materials), electrolessdeposition (non-current activated wet chemistrymethod of depositing metal) and electroplating.

Riskfaktorer för uppkomst av neurologisk sjukdom vid infektion med EHV-1

During the cultivation season there are a several cropping activities to carry out. At what time these activities are carried out is affecting the result and also on the economy of the crop production. As the production costs are high in potato production, it is important to keep an eye on the economy. Profitability is the most important factor in most crop production systems. If the costs are not covered, it is difficult to justify the production.

Säker mat i skolan?

Laws and regulations govern the school kitchens in Sweden. The municipality controls how well the school kitchens obey those laws. An annual fee covers the municipality?s expenses for the public control of the school kitchens. To be able to calculate this annual fee, a risk evaluation needs to be done.

När kultur var i rörelse : Kulturbegreppets förändring under sextiotalet, speglad genom tidskriften Ord&Bild

The aim of this thesis is to analyse and problematize the concept of culture and its changes during the 1960s. By examining articles out of the periodical Ord&Bild 1962-1972, I show how an aesthetically marked concept, closely related to the concept of art, changes into an anthropological perspective where attention is drawn to the social, economical, political and ideological aspects. This change is viewed in relation to the works of three prominent cultural theorists from the 1960s: Raymond Williams, Marshall McLuhan and Herbert Marcuse.The change that the concept of culture undergoes can be illuminated in several ways. Epistemologically questions of art, its objectivity and relation to reality, are replaced by questions of the function of art and of its role as reproducing ideas and norms of a bourgeois society. Economical and social aspects are used as critical factors in discussing the role and conception of culture, a perspective that gives the discussion a political and ideological edge.

Hemma är där hjärtat finns : en produkt till det resande barnet

Travelling children is the topic of my work. Children who commute between more than one home. Society is rapidly changing and so is the concept â familyâ . The nuclear family is no longer the most common one. Children are now travelling more frequently than ever.

Framställningen av Judas Iskariot : En förändringsprocess?

The purpose of this essay is to identify the criticism that has been directed towards the traditional description of Judas Iscariot as a traitor. After a survey and analysis of the critical revisionists' arguments, a discussion follows regarding the possible effects this may have on future ways of describing Judas Iscariot.Based on the results that have been elucidated, this essay concludes that the traditional description of Judas in recent times has been forced to endure fairly strong criticism. To summarize this criticism, the main argument raised by today?s revisionists consists of linguistic and historical phenomena. According to these Judas Iscariot has been subject to a, according to some, deliberate demonization; where he over time has become portrayed as more blameworthy.

Lodgepole pine - stability after thinning

SCA has today almost 300 000 hectares of their forest land planted with lodgepole pine(Pinus contorta var. latifolia). Due to initial extensive planting in the 1970ies the area oflodgepole pine forests in the thinning age has grown rapidly from the end of the 1990ies.During the years 1996-2005 first commercial thinning of lodgepole pine at SCA took place.The goal of the hereby presented study was to investigate the growth and stability in thosefirstly-thinned lodgepole pine stands a few years after thinning. Furthermore, the objectivewas to investigate the relationship between stand stability and different stand parameters.Additionally, lodgepole pine stem quality was estimated.The study is mainly based on the data collected during an inventory project carried out atSCA in 2008. Altogether 91 lodgepole pine stands in northern Sweden were measured afterthe first thinning.

Används både formativ och summativ utvärdering i ett projekt?

In companies today, it is becoming more and more common for employees to work in a project based environment, as a result many companies have developed their own project models. Companies with a well developed product culture are striving to improve their existing models, and businesses relatively new in the marketplace are aiming to reach a high level of maturity as well as reach high levels of efficiency in the shortest time possible. As the number of mature and efficient companies with well developed project model increase, so does the level of competition in the market. Since a well developed project model often leads to a more efficient and accurate way of carrying out the project, which in turn leads to shorter delivery time towards the client. This is crucial as time is one of the most valuable parameters of competition in today?s business environment.

VILKEN STRANDVEGETATION BIDRAR TILL DET ORGANISKA MATERIALET I KUSTN?RA SEDIMENT? Kols?nkor/k?llor, nedbrytbarhet och eDNA sp?rning

Coastal sediments are important carbon sinks, storing organic matter and thereby helping to reduce the amount of greenhouse gases in the atmosphere. However, they can also act as carbon sources if the deposited organic matter decomposes rapidly, contributing to increased greenhouse gas emissions and global warming. Rapid decomposition partly depends on the degradability of the material itself. In this literature review, I examine which coastal plant species dominate different locations along the Swedish coast, based on coverage data from the ClimScape project (www.climscape.se). For the most dominant species, I investigated the type of organic matter they may contribute to the sediments and based on those results I qualitatively assessed which sites that may function as carbon sinks or sources.

Idrottande ungdomars attityd till doping : - En studie bland idrottsgymnasister i Karlstad och Torsby

Sports research in the field of social science has shown that regular physical activity leads to wellbeing and positively affects the quality of life. A natural part of being an athlete is learning the functions of the human body, and what?s harmful and destructive, such as drugs (RF 1995). Doping is a constant problem in professional sport. Doping and manipulation of medical preparations in order to maximise performance is one of modern sport?s major problems, according to Blom and Lindroth (1995).I thought it would be interesting to see what the next generation of athletes thinks of doping.

En studie om möjligheter att stoppa förfalskningar : Spårbarheten i en global värld

The purpose of this study is to describe the traceability of products that protect against counterfeiting and examine how protection against counterfeit products have been developed to date, and to display the opportunity to streamline the protection of products and brands.Nowadays, in the global world, it is getting increasingly more difficult to track the products. Especially for the last link in the chain, which in most cases is the customer and who is constantly exposed to risks. This report deals with the possibilities of preventing and detecting counterfeit products. Fake products are not unusual in an historical perspective. It has been common with counterfeits ever since the Middle Ages continuously until today. Forgers have become more skillful and they are successful in most industries. Many of the fake products are of poor quality and can be downright dangerous to the customer.To answer the question, the author used a qualitative collection method.

Conflict Resolution in West Africa: A Comparative Analysis of Sierra Leone and Liberia

This paper is a Master thesis for the Master?s program in International and European Relations in the Department of Management and Economics at Linköping University. As the title indicates, the aim of this thesis is to make a comparative analysis of the conflict resolution initiatives that were employed in the Sierra Leonean and Liberian conflicts. The research questions are: ? What were the root causes and trajectories of the Sierra Leonean and Liberian conflicts? ? What were the conflict resolution initiatives employed in resolving both conflicts? ? Why did the Lome Peace Accord succeed in the case of Sierra Leone whilst the Abuja Peace Accord failed in bringing peace to Liberia? In order to answer the afore-mentioned questions and fulfil the aim of this paper, a qualitative research method has been chosen.

Subjektiv och objektiv bedömning av underlag på svenska hopptävlingar på elit- och nationell nivå

Bark-stripping by red deer (Cervus elaphus) cause extensive damage to economically valuable spruce trees (Picea abies) in Swedish forests. The underlying causes for bark-stripping are not fully understood, and the frequency and severity of damage unpredictably differ between regions. In this study, I investigated if landscape structure (e.g. agricultural dominated landscape opposed to forest dominated landscape), forage availability, population density and disturbance (e.g. roads and settlements) affect bark-stripping frequency.

The Way We Produce : Möjliga kvalitetsförbättringar på Atlas Copco

The purpose of this master?s thesis was to find problems that occur in the production line at Atlas Copco Rocktec Division, in order to decrease the costs of defect in quality. When the problems were distinguished, the authors ought to choose the problem with the highest improvement potential. One request from the constituent at Atlas Copco Rocktec Division was to connect the improvement to the document The Way We Produce. The document provides information and values about Atlas Copco and consists of 10 principles to be able to reach their vision.

Taggade bibliotek ? en studie av adoptionen av RFID på svenska folkbibliotek

The purpose of our research was to examine whether the acceptance and diffusion of RFID technology among the employees at public libraries in Sweden, follow the classic diffusion of innovation model. RFID or Radio Frequency Identification, is a technology that uses radio frequency and microchip technology to track items, in our case, library books and other library materials. Diffusion is the process by which, in our case, the RFID technology is adopted by the library staff. The purpose of this study was to examine what factors influenced the acceptance and adoption of RFID among the library staff. We used Everett Rogers' Diffusion of innovation theory as our framework.
