Vattenkvalité i Märstaån : Igenväxning som indikator på närsaltläckage och vattenstatus

The purpose of this study was to examine whether an inventory of the vegetation overgrowth could be used to indicate a locally nutritional impact. The study was conducted at Märstaån where the water runs through a number of agricultural lands that could lead to an increased amount of diffuse emissions of nutrients. The vegetation overgrowth in the water was also studied in relation to shade, meandering and water flow effects on the vegetation. With this method, no definitive conclusions could be drawn.Where the water was shaded, no vegetation overgrowth could be found. Therefor trees should be planted to prevent any future overgrowths.

Balkanisering och klassifikation : En komparativ studie av klassifikationen av forna Jugoslavien, beträffande språk, geografi och historia, i DDC och SAB

This master's thesis examines the possibilities of correction and change in a classification scheme, with regard to the changes that occur in the world the classification system intends to describe.Applying a comparative method and classification theory, the classification of the example of the former Yugoslavia (1918-1941, 1945-1991), its republics and successor states, and the languages, formerly known as Serbo-Croatian are examined through a comparison of the main classes and divisions of language, geography, and history, in Dewey Decimal Classification (DDC), and Klassifikationssystem för svenska bibliotek [Classification for Swedish Libraries] (SAB). Eight editions of DDC, from 1876 to 2014, are compared to seven editions of SAB, from 1921 to 2013. The editions have been selected in order to show the changes prior to, and following, the First World War, changes after the Second World War, and changes following the collapse of Yugoslavia in 1991.The examination shows that both systems have updated their editions according to the changes in former Yugoslavia over the years. DDC has well constructed facet schedules, especially Table 2 concerning geography, but fails, in some cases, to construct a logic and hierarchical structure for the republics and languages of Yugoslavia, partly due to the fixed classes and divisions that survive from the very first edition of DDC from 1876, but also as a result of the decimal notation, and its limitations, itself.SAB seeks to construct a hierarchically logic and equal scheme for the languages, areas, and states of the former Yugoslavia. Although the facets for geography and chronology aren't as developed as the ones in DDC, the overall result is that of a logically consistent and hierarchically clear classification, with short notation codes, thanks to the alphabetic mixed notation, which allows more subdivisions than the numerals and the pure notation of DDC.This study is a two years master's thesis in Archive, Library and Museum studies..

SAB-SYSTEMETS AVDELNING Y : Dåtid, nutid, framtid

This Master's thesis concerns the classification of compact discs according to the Swedish classification system, SAB. The purpose of this thesis is to critically study and discuss category Y of the SAB-system and its application in Swedish public libraries. The classification system has undergone great changes from the first edition in 1921 until today. In 1921 there were no musical recordings in Swedish libraries, today they are responsible for a large part of the loans. We discuss how the system's category Y has corresponded with the musical development.

Irrigation scheduling for efficient water use in dry climates

In this report the importance of irrigation scheduling in dry climate is shown, how it can save water and energy; how this method can improve crop yield by supplying the right amount of water at the right time. It is shown how irrigation scheduling and irri-gation technology together increase the irrigation efficiency..

Vatten som säkerhetsfråga : Med FN:s konstruktion av vattenfrågan som utgångspunkt

ABSTRACTThe aim of this study is to analyse if the UN today constructs the water issue as a security issue and to argue about in which way the organization in that case does so alternatively why it can be said that the UN doesn?t construct the water issue as a security issue.In order to reach this purpose the following questions will be answered:?Does the UN construct the water issue as a security issue today?-If yes, in which way?-If no, why can it be said that the organisation doesn?t?The methods used are qualitative literature studies of policy documents on water from the UN. The focus is to analyze the ideas about water and to apply my theory on the concept of security, which is Barry Buzan?s framework on security, to these ideas.The main results showed that the UN strongly constructs the water issue as an environmental security issue for environments and species and in relatively strong terms also constructs it as an environmental security issue for civilisations. In rare cases the organisation constructs it as a societal security issue, but the UN doesn?t construct the water issue as a military, political or economic security issue..

Hållbart nyttjande av vattenresurser på Gotland : vision och verklighet

Fresh water has become more and more of a scarce commodity. Water scarcity isn't first and foremost a cause of drought and wasting, but a cause of inequality and mismanagement. This is not only a problem for developing countries, and there can also be variations within countries. The municipality of Gotland has a development program called Vision Gotland 2025, with goals for growth and sustainable development. The aim of this study is to examine whether the use and management of water resources on Gotland and Vision Gotland 2025 is conformed to the Water Framework Directive and the Ecosystem Approach in terms of sustainability.

Alternativ hylluppställning: en undersökning av hylluppställning och biblioteksmiljö på Västerviks stadsbibliotek.

The purpose of this Masters thesis has been to study the changes made in shelf arrangement and library environment in a Swedish public library. The aim was to examine the reasoning done by the library staff regarding classification, the Swedish classification system SAB and changes in library environment. The basis of our study were three questions: 1. Why has Västervik public library made changes in the shelf arrangement? 2.

Vattnet i vår kropp : Förskolebarns tankar om vattnet innom oss

AbstractThis study deals with preschool children's ideas about water in our body. Ten children with the age of four to five were interviewed individually, the interviews were qualitative. The children were also asked to draw their answers and answer questions about a picture that represented the excretory system. The results of my study show that children did not have any knowledge about the water being vital for us. Preschool children had no knowledge of why it is important to drink water.

Kontextbaserad utveckling av klassifikationssystem: Värdet av ett användarperspektiv i en beståndsorganiserande process på specialbibliotek

This thesis treats a new perspective in the theory of classification, the context-based approach. The aim is to find out what kind of value this new approach can have in the process of creating a classification scheme for a special library collection. The first question to be answered is how the context-based approach works in a real life. The second question investigates which role the research in this particular area might have. Illustrating a real-life situation, the unit of Rättsmedicinalverket in Linköping serves as the object of study.

Om associationer till vatten

This paper is intended to provide a picture of which associations water can wake in the human mind from the perspectives of garden history as well as from that of environmental psychology. I hope to paint a fairly broad picture of our perception of water that can serve as a basis for discussion and as a starting point for different forms of design work in landscape architecture. The historical perspective emphasizes the importance of water as a condition for the emergence of gardens and in a wider perspective the importance of water in early cultures. Also, I describe a picture of how water has been used throughout the history of gardens from early Egypt to the baroque era. The garden history analyzed from an art historical perspective gives a picture of human associations to water, and the history behind these associations is presented. As a compliment to the art history approach, I have chosen to highlight our associations with water from the perspectives of environmental psychology and evolutionary science.

Serveringskärl för restaurang

The water company MittSverige Vatten (?MidSweden Water?) located in the Medelpad, Sweden was in need of a moreexclusive water carafe for restaurants and conference in the region. Current design solution was not able to cope with thedemand of a more exclusive setting and was not promoting the company in a good way. In the beginning of the projectit became clear thru an intense interview period that there was at least three directions for design solutions the companycould go for.? A carafe (exclusive settings)? A pitcher (conference and lunch servings)? A water dispenser type (serving of larger amounts of water during a certain brief periods of time.)It was decided to go for the exclusive one.Small pieces of rock from the last ice age turned out to be a vital component of the new design concept for the company..

Kvinnan:mannen::alternativet:normen ett feministiskt perspektiv på klassifikation

Using a feministic perspective and a critical approach, my purpose is to discuss bibliographic classification, a central aspect of Library and Information Science. More specifically, my aim is to demonstrate the norms and the dominating thoughts regarding the organization and representation of knowledge, subjects, and social categories in classification systems. I review previous research involving critical approaches to classification. These show that classification systems are a reflection of the context in which they are created, with the result that universal assumptions can be questioned. Some studies also present problems inherent in hierarchical structures.

Att organisera beståndet eller ?Äntligen hittar man!? : om hylluppställning och exponering på Arkenbiblioteket

The aim of this master?s thesis is to examine how libraries can organize their collections in terms of library shelving and displays and to what extent these activities stem from a desire to create a user-friendly library. The thesis is based upon a case study of Arkenbiblioteket in Sweden and the material consists of a literature study and qualitative, semi-structured interviews with three librarians at Arkenbiblioteket. The theoretical framework consists of theories on information-seeking behavior, classification and displays. These theories form the basis of the analysis of the empirical material.The main reason for the changes in shelf arrangement at Arkenbiblioteket was a desire among the library staff to create a user-friendly library.

Hållbart jordbruk inom vattenskyddsområde : En studie om Sverige, Danmark, Frankrike och Tyskland

To guarantee protection of our drinking water, water catchment protections are established. These are divided into three different zones and in the first zone it is most likely that an activity, such as agriculture, will contaminate the water resource. Hence the activities are strongly regulated or banned. The EU communion is working towards a sustained water quality through several directives; Nitrate Directive, Waterframwork directives and Sustainable use of pesticide directive. The main purpose is to regulate the diffuse pollution from agriculture.This thesis is about how Denmark, Germany and France are working towards a sustainable agriculture within water protection areas.

Mälarens vattennivå i ett framtida klimat

The discharge from Lake Mälaren is regulated to keep the lake water level within limits set by a water decree. Despite this, in the year 2000 the lake water level rose above the upper limit. Studies conducted at the climate modeling unit Rossby Centre at the Swedish Meteorological and Hydrological Institute (SMHI) indicate that the inflow to the lake may increase in the future. A flood in the area will, among other things, strike infrastructure and residential districts.The aim of this study was to investigate the water levels of Lake Mälaren in future climates. In addition to this possible future expansion of the lake discharge though the sluice gates in order to keep water levels below limits set by the water decree and to prevent flooding of the shoreline were discussed.
