Ear piercing performed in hairdressing salons and jewellery shops using a piercing gun has been set aside from the obligation to notify the local environmental and public health authorities, due to the use of disposable cassette with the piercing gun. According to the Swedish environmental code each practitioner are required to prevent any health hazards arisen from the operation. Local bacterial infection is the most frequent complication associated with the ear piercing procedure and to prevent the potential risk of such an event, hygiene conditions in both the premises and in procedures are essential. The purpose of the report was to examine the presence of ear piercing practitioners in Umeå and their current hygiene conditions. The study consisted of interviews with employees and managers on site whose answers was evaluated and compared to the general recommendations of The National Board of Health and Welfare.

Sycamore maple (Acer pseudoplatanus L.) is a common broadleaved species throughout Europe, however often of minor interest to the forest sector. There is currently a lack of research on sycamore maple, and some of its characteristics have throughout history contributed to a negative reputation in both literature and the forest society. Since broadleaved species in general are of great importance to the forest sector in Europe and presumably of enhanced significance in the future, deepened research is needed and particularly Swedish. With a desire to hopefully increase the interest for sycamore maple, was the objective of the study to examine the current status of the sycamore stands in southern Sweden. The study was carried out both as a survey with inventory field work and as a literature study. Parts of the latter mentioned is also presented in the introduction. The study shows that the majority of the sycamore stands in Sweden are growing well, producing fairly high qualities and volumes.

This master thesis covers the development of an automatic tuning process for the existing speed controller for drive systems. The drive systems are resonant two-mass systems where a motor is used to drive a load connected by a shaft. The developed method relies heavily on system identification and the construction of a complete mechanical model of the process. With this approach, the common problem with poor load speed control that derives from measuring only the motor speed can be addressed and solved for a majority of such processes.The automatic tuning method has along with general test functions been implemented in a complete tool for automatic tuning, testing and performance evaluation and reporting for drive systems..

The economic conditions for Swedish dairy farmers are constantly changing. The numbers of producers are declining and the economic conditions for dairy production are weakening debilitating. To improve the economic situation for a farm a hired contractor is a possible solution since previous studies show that machinery cooperation may be beneficial for the farmers. The aim of this study is to examine the possibility for farmers to cut costs by hiring a contractor for harvesting silage. A comparison between using own machinery and hire a contractor is the starting point of this study. Another aim is to discuss the farmer?s decision process when achieving today?s situation and to determinate what factors affect their decisions. The study is based on cases selected from four farms that today have chosen not to or only to some extent, hire a contractor for harvesting silage.

In this project the focus has been on the system for recombination at Oskarshamn 2. The recombining systems have on several occasions switched paths due to low pressure before the last ejector that?s feeding the recombiner. Of the mentioned reason, events and several measuring points have been analyzed in this report since the installation of the recombining systems.In order to prove theories and demonstrate what may be the cause of this problem, we used heat balance calculations by the program Probera. Using the program, we can demonstrate that the catalytic process does not reach the desired temperature with the amount of combustible substance.

The primary purpose of this thesis is to investigate the operation of membership criteria, which are applied against countries that wish to join the European Union (EU). More specifically, the importance of some criteria in comparison to others is considered. To answer this proposal, three questions are posed: What are the EU membership criteria? Are some criteria more important than other criteria? Does the EU treat candidate countries differently in applying the membership criteria? Three countries are used in this analysis, each country representing one recent enlargement round: Poland (2004), Romania (2007), and current candidate country Turkey. Both official documents, such as EU treaties, and unofficial documents such as statements from EU leaders are used to analyze the application of membership criteria.

The report handles the transmission of signals from piezoresistive pressuresensors and thermocouple from a rotating object. This report also evaluates the possibility to collect data in a datalogger that rotates with the object. Telemetrics was previously used for signaltransmission in Finspång, therefore there has been no tests considering preassure measuring. One transmitting method handled in this report is transmission through a slipring connection. One test with a slipring connection was performed for transmitting signals from a piezoresistive preassuresensor.

In this essay I discuss and analyse if we can witness any signs on regional dimension due to regional representation from our elected representatives in the five constituencies Malmö, Blekinge, Norrbotten, Uppsala and Stockholm. Two seperate terms of office between 1991-94 and 1998-2002 has been compared. In political science there has been much debate about the relationship between voters and their elected. By measuring each and everyone elected representatives in the work of produce introduced bills towards their own constitiency during both terms I have tried to see if there is an occurence of a regional dimension.The theory that´s been applied is based on geographical representation where one might aspect that central metropolitan areas and peripheral regions is somewhat over-represented in legislatures. By using a method of comparison between the five chosen constituencies and theirs elected representatives I have come the the conclusion that there is a weak tendency that this might be the case seen to a regional dimension perspective..

The use of a bit in the mouth of a horse is being increasingly questioned with respect to its actual function, and is sometimes judged an obsolete instrument of control with potential to injure the horse. The objective of the research presented herein was twofold; firstly, to investigate the actual pressure load in the mouth of the horse with regard to oral health issues, and, secondly, to investigate whether this could be a viable method to objectively measure strength exerted by a rider/driver to the mouth of the horse especially with regard to training regimes. From the results, it is evident that these newly developed sensors have a future in equine research, although they are still under development. They can be useful both as a pedagogic teaching instrument, providing instructor and pupil with instantaneous, objective feedback on the contact between hand and mouth, as well as an aid in measuring pressure loads from our common bits. .

The current standards for design of steel beams are divided into four classes based on the slenderness of cross-sectional parts. Depending on the section class a beams load capacity is either determined by a plastic, elastic or a reduced elastic model. The division between cross-sections calculated by a plastic and an elastic model is today done in a very harsh way with no smooth transition. This leads to a large difference in the calculated resistance for the sections located near the class limits. Elasto-plastic sections are in the current situation calculated as purely elastic and their large plastic reserve is not considered in the current standards.

During adolescence the teenager tries to become an independent individual, something that for many individuals can be experienced as"a hard time". In early childhood the individual was closely connected to the parents, but during adolescence friends and new contacts become more important. Studies in developmental psychology have most often adopted a parent-perspective, which is why a child-perspective is required. The aim of this study is therefore to measure the teenager's relationship with parents and friends and to look for possible correlations between these. As a means of measuring quality in the relationships, the IPPA, the Inventory of Parent and Peer Attachment, was used.

This thesis provides a systematic literature review of a selection among current papers andarticles on Green Information Systems (IS). The main focus is on the current state of Green ISin academic research. This study aims at gaining a deeper understanding and a clearer view ofthe state-of-the-art of IS for environmental sustainability research, with the goal of clarifyingthe diffuse idea of what Green IT/IS is, and what differentiates Green IS from Green IT.To support the objective of this study, the articles selected for data analysis were collected byusing a systematic literature review as research and analytical method. Within the thesis, adescriptive angle with an interpretative character is used to analyse the data extracted.A theoretical framework based on concepts from sustainability, Green IS and Green IT isemployed in order to analyse and compare terminologies and frameworks used in the studiedarticles. Furthermore, the different dimensions of sustainability and the various terms used todescribe Green IS are analysed comparatively.The result and analysis are discussed in a conclusion confirming the on-going ambiguity ofthe terms Green IT and Green IS and the transformative power of IS.
