Mätning av ekosystemtjänster i jordbrukslandskapet :

Abstract In order to make the modern agriculture less dependent on non-renewable external inputs, it has to rely more on ecosystem services. The agricultural system produce not only food, fiber and fuel, it also generates other ecosystem services such as e.g. photosynthesis, recycling of nutrients, influencing local microclimate, pollination, biological control and detoxification of noxious chemicals. This study is an attempt to get a better understanding about the interaction among different ecosystem services and different habitats capacity to generate them. An evaluation of eight different methods is done. The ecosystem services studied are the ability to absorb solar energy, biomass production, botanical diversity, decomposition and natural predation of aphids.

Miljöutredning : ett fastställande av betydande miljöaspekter samt lagar och krav som rör Skaraterminalen Spedition AB

The ability to tackle NP-hard problems has been greatly extended by the introduction of Metaheuristics (see Blum & Roli (2003)) for a summary of most Metaheuristics, general problem-independent optimisation algorithms extending the hill-climbing local search approach to escape local minima. One of these algorithms is Iterated Local Search (ILS) (Lourenco et al., 2002; Stützle, 1999a, p. 25ff), a recent easy to implement but powerful algorithm with results comparable or superior to other state-of-the-art methods for many combinatorial optimisation problems, among them the Traveling Salesman (TSP) and Quadratic Assignment Problem (QAP). ILS iteratively samples local minima by modifying the current local minimum and restartinga local search porcedure on this modified solution. This thesis will show how ILS can be implemented for MSA.

Bojkonstruktion

The division of Electricity at Uppsala University runs a project called Lysekil project, they have designed a buoy that uses the waves to create electric power from a generator attached to the bottom of the sea.Uppsala University is closely connected with the company Seabased and the university makes use of their facilities in Lysekil. When they designed the buoy issues occurred, the geometric design was flawed, brackets with a short shelf life and it is generally uneconomic.A study visit was done in Lysekil on Seabased facility. With this visit the project started, which is to improve the design of the buoy and the attachment of wires leading to the generator. In this project we have chosen to use a beam system with three beams that are attached to the buoy. Then a wire attached to a plate that sits between the beams will be leading to the generator. Two proposals for construction are created, what distinguishes them are the brackets between the beams and the buoy.From these constructions, the design that is considered most optimal for our project is chosen.All parts of the buoy have been modeled and the drawings are designed in ProEngineer software.The two constructions are compared with each other, but the whole focus is on the second and final structure. The report begins with an introduction describing Lysekil project, and a task description of our project.The project aims to produce an optimal buoy that will be easy to design, materials restrictive with good durability and an economical solution.Wave power true function has been studied, mechanical and finite element analysis of beams, buoy and plate design.This has been presented in this report, where in the various chapters can read more about the processes. Although the relevant facts and information on this project and buoy development is included.

Läkemedlet Oxazepam påverkar abborryngel : Exponering under embryonalutvecklingen ger effekter på tillväxt, överlevnad och beteende

Pharmaceuticals are environmental pollutants that are a major threat to aquatic ecosystems and very little is known about their ecological consequences. In this study growth, survival and behaviour (sociability, activity and boldness) of perch fry (Perca fluviatilis) were examined in order to study the possible effects of exposure to a benzodiazepine anxiolytic drug, Oxazepam, during embryonic development. The study tested following hypotheses: (1) perch growth is affected positively by exposure during embryonic development; (2) early perch survival is affected positively by exposure during embryonic development; and (3) boldness and activity increases while sociability decreases in perch fry exposed during embryonic development. Embryos of naturally spawned perch were exposed to water with two different concentrations of Oxazepam. The embryos were exposed during different parts (24-hour periods) of the embryonic development, because embryos may be more vulnerable at certain times during embryonic development and/or because the exposure at different times can produce different effects.

Implementering av miljöledningssystem i skogsbruket : en fallstudie hos Stora Enso Skog AB

Environmental management systems are a way of systematizing and streamlining an organization's environmental efforts. Within its EMS the organization determines it´s environmental policy and various environmental objectives. In order to achieve their environmental objectives the organization produces action plans that describe how they will work towards the objectives. Stora Enso Skog AB´s districts have been assigned to produce action plans for the company´s environmental objective of 90 % approved everyday nature consideration in final felling and any targets included within this objective. The purpose of this study was to investigate how the districts work with these action plans and how this could be improved.

Vilken roll spelar verktyget? : Datorns betydelse för gymnasieelevers skrivande och texter

The aim of my study is to investigate if and in that case how the writing process and texts written by students in the upper secondary school are affected by the writing tool; does it matter if they write their texts on a computer or by longhand? Another objective is to compare such an effect with the findings of previous studies performed on earlier generations of writers. The first part of my study was a survey. It showed that two thirds of the 67 students participating thought that they would have written better texts in the national writing test if they had been able to use computers. In the second part of the study each of the fourteen participants wrote one text on computer and another by hand.

Om fototextpoesi : Läsningar av mötet mellan fotografisk bild och poetisk text

What is the relation of image and word, of sentences and pictures? What kind of message does this combination produce when juxtaposed on a single material plane? And how do we read its ?infinite? relation? These are the questions at the center of this inquiry. My main interest concerns the exact nature of the relation between photographic images and textual elements of poetic language when these are juxtaposed in what I call Phototext poetry.The thesis calls into question the conventional reading habits of the conjunction of photographs and texts, and seeks to understand the more complex connections intrinsic to the relation image/word and its material and perceptual play in poetic works. Does a text always ?anchor? the multiple meanings of an image, as Roland Barthes argues? What if the alterations of an image could ?anchor? certain fractions of a poetic, polysemantic textual construct? Is a photograph indifferent to the visual, material permutations of texts that certain contemporary poetic practices produce?I discuss phototextual works and collaborations of various kinds, from Molin fontän [?Molin?s fountain?] (1866) over classic surrealist poetry to language-oriented writing.

Playplus : Utveckling av produktkoncept för aktivitets- och inlärningsmotiverad lek

In a society where adults set the conditions for children?s play and generate modern and at times technically advanced products, fundamental characteristics like simplicity, opportunities for motor skills training and learning tend to be neglected. Owing to this, the Linköping-based company Time In wants to introduce a new multifunctional product, which differs from other products in shape and function and lives up to the often overlooked, basic characteristics in a toy.With Time In as the assigner, the purpose of this master thesis has been to use simple means to produce a "learning by playing" concept. Since Time In sells toys and products suitable for children in nurseries and preschools, the development of the products has therefore included a study of nursery and preschool environments.The thesis has been carried out within the Product Design subject area at the Department of Management and Engineering at Linköping University. Concept development has been done in three phases: the Preparation phase, the Design phase and the Presentation phase.

Authors: Philip Trollér & Jasmin FrljevicTitle: A sharp striker or forwardLevel: Bachelor of JournalismLocation: University of GothenburgLanguage: SwedishNumber of pages: 62All throughout time the Swedish language has been influenced by various external languages. And throughout the years many loanwords have been introduced to the Swedish vocabulary. And this phenomenon occurs in the texts written by Swedish sport journalists. But in what extent do loanwords from the English vocabulary occur in texts written by Swedish sportjournalists, in what types of texts they can be found. And also why the usage of loanwords occur.The purpose of our study is to find out how frequent English loanwords are in Swedish sports journalism.
