Due to exploitation of the world?s rivers, the upstream migration of anadromous species is frequently delayed or even prevented. To mitigate these problems and allow fish to migrate past obstacles, structures such as fish ladders have been developed. However, recent studies show that many of the present fish passage facilities are deficient. Monitoring and evaluation of passage facilities is therefore crucial to enable necessary adjustments.

Use of lighting is crucial to make public urban places available during dark hours. Landscape architects participate in planning of lighting, but during our education there is very little taught on the subject. Through this study we approach the subject of lighting by looking into lighting methods for urban plant materials during winter. In this thesis we look into ways to emphasize the visible characters and experiences of urban plants during winter season using light. Target audience are landscape architect students and landscape architects without knowledge of lighting. The part of the thesis that describe basic conditions for, and visual characters of plants can be useful to lighting designers without knowledge in this subject. Working methods used were the following: ? Pre-study about light and lighting techniques through literature and dialogues. ? Compiling important visual winter plant characters through photography and literature. ? Outdoor light experiments with plants.

The background for this degree thesis is a need to replace the existing seal used to protect equipment containing secret or sensitive equipment used by Swedish Defence. The target design should satisfy both the need for tamper evidence and reduce Life Cycle Cost. In developing a new design for a seal, additional benefits such as improved logistics support and indication of attack methods such as heat and solvents have been considered.The lack of guiding principles for end users of seals became evident during the interviews. Major concerns for the future are education of users, information about actions if a seal is broken and user liability.The design work was divided into several phases. A feasibility study was performed including investigation of theory of labels, materials and possible technologies.

Purpose: The purpose of this essay is to describe the social media usage of five European official national tourism organizations (NTO). The essay proceeds to discuss and evaluate the findings, whilst reflecting on the advantages of social media usage from the point of view of an official national tourism organization.Method: The authors used three different methods of research: one structured observation to study the national tourism organizations? everyday work in social media, one field stimulation to study if and how different NTO respond if a prospective visitor makes them a direct question via social media and finally an email interview to gain insight into NTO?s underlying strategies and policies about social media usage.Theoretical framework: The theories that have been used in this paper include the Uses and gratifications model, theories of one-way and multi-way communication, theories of social media and relationship marketing.Conclusion: By making use of social media the company releases some of its control to the customers as the latter can express their opinions freely in this type of media. One of the advantages of social media is that the platform favors dialogue and feedback. Social media can be used for traditional one-way communication, but works best as a supplement to the regular marketing activities, allowing the activities on social media platforms to focus on branding and building long-term customer relationships.

The power system modelled in this thesis work has been developed for simulationwhen e.g. the production in some part of the power system is changed. The powersystem has been modelled according to the swing mass of the system, the frequencydependency of the load and the turbine governor. The model determines the systemfrequency, the period of regulation and the power exchange between the differentsubsystems in the Nordic synchronized system.In this model the system frequency is assumed to be the same in all different parts ofthe power system and the voltage conditions in the power system are neglected. Forthat reason power swings does not occur between different subsystems in the powersystem, which usually occur as a result of the swinging connection between thetransmissions line.

Ett av de mest omtalade fenomenen de senaste åren har varit den snabba utvecklingen av digitala medier och sociala nätverk. Teknologin har utvecklats från att ha varit något som användes ibland och var till för arbete och underhållning, till att vara en stor del av livet och för vissa en nödvändighet. De nya medierna och sociala nätverken är idag en stor del av mångas vardag och påverkar hur vi tar in information, kommunicerar och utrycker våra tankar och idéer. Under de senaste åren har allt fler organisationer valt att ta in sociala medier i sin marknadsföringsstrategi och organisationerna har företagsprofiler på bland annat Facebook och YouTube för att kommunicera med kunderna. Yngre generationer har växt upp med tekniken och sociala medier vilket är en resa som äldre inte har följt med på och därför är en vanlig uppfattning idag att endast yngre generationer använder sig av de nya mediekanalerna.

???Information Technology is an essential part of the society today, not least in large ???organisations dealing with sensitive information. An example of such an organisation is the Swedish Armed Forces which indeed is in the need of ways to ensure information security in their Information Technology systems. The means which is used is an authorisation and accreditation process.All Information Technology systems go through a life cycle which includes realisation, usage, development and liquidation. In the Swedish Armed Forces the lifecycle is an authorisation process.

In a time of fierce global competition, where an immense amount of commercial messages reaches consumers around the clock and in every conceivable context, companies constantly seek to find new ways to reach out with their product. One way to do so, that has increased in popularity in recent years, is the use of gift bags. A gift bag may contain samples, miniature products and even products in full size, as a rule from several different brands, which the recipient receives free of charge. The gift bag is typically distributed at some form of event, such as store openings, fashion shows, theme parties and the like, and the receiver of the gift bag can then evaluate the content without any obligation to purchase. The ambition of the companies that choose to participate with their products in a gift bag is, of course, that the recipient will find their products satisfactory, and ideally, that he or she will continue to consume the brand in the future.There are numerous scientific research contributions related to the use of free samples, but very few that concern the gift bag, where a collection of samples from different sources and brands appear.

Background:The value a consumer connect with a certain brand and its design differ from person to person. This value ought to be investigated. Why does people buy expensive things when there are cheaper alternatives? Is it brand equity and/or the perception of a brand?s value that make a difference? People strive to show themselves and to perform through products, which makes it interesting to see to the perceived value of design.Tweens is a group of consumers that are easily influenced to consume products by their surrounding. To choose clothes, shoes and other products after what your surrounding?s demand, is a way of adapting yourself to society.

This master thesis is made of two parts. The first part concerns the method and results ofdesigning a motion control system for a piece of research-equipment called BIRGIT. Theequipment is made to be used for research on eyemovements. In the second part, a computermodel of a part of the balance organ in the inner-ear is developed. The work has been done atthe Bernadotte laboratory at S:t Erik Eye Hospital.The equipment the control system is made for is a so-called rotationchair.

Lining techniques such as nap bonding and mist lining were developed in the late 20th century and have gained popularity alongside with the increased use of acrylic emulsions as adhesives. The ability of the adhesive to create a nap bond to the canvases without penetrating the fibers has shown advantages regarding reversibility. In addition, the use of moisture, heat and pressure is reduced, which can be advantageous for more sensitive paintings. These lining techniques have been included in several studies where reversibility, minimal intervention and respect for the individual requirements and problems of each object have been the focus. The adaptability of the methods has been confirmed and to further explore the adaptability, this study consists of three simpler application techniques with the adhesive Lascaux 303 HV on mockups.

Women?s strive to reach higher leading positions and build a career that's combinable with child birth and private life, is an on-going debate among academics in the fields of leadership, management and organization. This bachelor level thesis is written at the section of Management & Organization at School of Business, Economics and Law in Gothenburg, Sweden, spring semester 2015. In our research methodwe have used source triangulation with a qualitative approach to the subject of egg-freezing in favour forcareer with a focus on Swedish workplaces. The purpose has been to illuminate, map out and further problematize how the introduction of the employee benefit in November 2014 can be seen to relate to social sustainability.A lot of the management research that discusses social sustainability tends to focus on how women (and men!) try to balance family life and career and how to combine (or to not combine) them.

This report contains a degree project made by the mechanical engineering students Lennart Andersson and Daniel Jansson. The project has performed in assignment by SOMAS Valves AB in Säffle. SOMAS are leading in development on control and on/off valves. To maintain this position they always want to improve their products. One way in this development is valves that are more tightened.The purpose with our project was to investigate another seat design on a HiCo (High Cobalt Alloy) seat to a SKV 150 PN 25 valve and compare this to an original HiCo seat.By modifying the seat on a ball valve we want to achieve a valve that leaks lesser then a valve whit original seat.

This is a qualitative analysis that, based on systemic functional linguistics, or SFL, and genre theory, has aimed to study the genre pedagogical implications on written language as they occur in narrative stories and expositions whilst the model is introduced. Systemic functional linguistics is a linguistic theory that views the organisation of language as functional options for meaning; language is a set of resources to channel meaning through realisation. Genre theory elucidates the pragmatic and educational uses of SFL in the categorizing of language in configurations of meanings as they are set and understood in different cultures.  The purpose of the survey is to do so with focus on successful and less successful writers by attempting to answer two primal issues:How is development of written language in reference to the introduction of the genre pedagogical model visible in the studied texts?How does genre pedagogical teaching influence successful and less successful writers as visible in their writing with a certain purpose?To answer these issues the survey is based on narratives and expositions written by high school students who have been divided into two groups according to the purpose of the survey. One text in each genre has been written by the students before and after lessons based on the genre pedagogical learning wheel explaining the relevant genres.

This thesis tackles the subject concerning arguments as a conceptual basis forunderstanding the general strategy of the European Union Commission on issuesconcerning EU-harmonized environmental taxes, politically delicate and intergovernmentaldependent. The Commission's official proposals, communications and other relevant documents are subject to inquiry, where the theoretical bases are that harmonized environmental taxes in the EU is an issue conceived as supported by academic debate, and where the institutional arrangement in relation to an European-national dimension alongside the discursive context, allows meaningfulspace for arguments. The study makes a distinction between substantial (environmental cancerns in itself) and instrumental (other benefits, mostly economic ones) rationality as a foundation in various types of arguments.The study's main findings are that the Commission's official documents over the past 20 years, have been trying to keep a strong image of reason and knowledge based arguments for an EU-wide environmental tax reform. In particular, the types of arguments tend to appeal to the Member States by stressing the instrumental rationality in a European environmental tax reform, indicating the value of good arguments as a part of the Commission's main strategies. In sum, this may have further theoretical suggestions concerning questions of environmental and elimate change policies in a European context or other more general studies relying on theoretical assumptions of logics of argument, legitimacy or studies of motives behind action strategies in politically sensitive issues such as taxation at supranationallevel..
