Oregistrerad gemenskapsformgivning - Svaret på problemen med formskydd för modeprodukter?

In the year of 2002 a new council regulation on community designs was implemented. In the beginning of the essay the legal situtation before the implementation is investigated and part of the purpose is to evaluate if it constitutes a solution to the problems with protection of fashion designs that existed then. Because fashion designs more or less were excluded from protection during the period before the implementation the fashion business developed a habit of unauthorized reproduction. This attitude among the market players is a central point of the essay. The essay starts off with a review of the earlier lack of possibilities regarding the protection of fashion designs.

Excel-baserad beräkning och dokumentation av distansskyddsinställningar

This is a master thesis work carried out at the Department of Energy and Environment atthe Division of Electric Power Engineering. The master thesis work describes the theoryof distance protection relaying in 130 kV meshed distribution networks. The main aim ofthe thesis was to construct an Excel application for calculation and documentation of thesettings for distance protection relays. The program is based on general methods forcalculating settings of the different zones for the distance relay and presents the settingsin simple graphics using quadrilateral characteristics.The reason for building an Excel based application is the great variety of distanceprotection relays in live networks. The manufacturers of distance protection relays makeprogram for documentation available, however, they are based on the typical settings forthe specific relays.

GIS och statistik vid dräneringsområdesvis kväveläckagebeskrivning i Halland

The last decades have shown increased nitrogen leeching from soil to water recipients. This is inSweden mainly due to over-manuring of agriculture land, effectivization of drainage systems and thedeclining extent of wetlands. The accumulated amount of nitrogen in water doesn?t only make itunsuitable for use by humans and cattle, but also decreases the biological diversity as well as negativelyaffect tourism and fish industry. In the most severe cases shallow maritime grounds can be completelydepleted of oxygen due to decomposition of the increased amount algae and plankton growth.This study have the aim to describe and quantify the nitrogen leeching from the Genevad drainagebasin, located in southern Halland, Sweden.

Uran i dricksvatten : litteraturstudie om reningsmetoder samt pilotförsök med jonbytesteknik

Uranium (U) is a naturally occurring component in bedrock and under the "right" conditions it can dissolve and move into the ground water. Since many people in Sweden depend on drilled wells as their main drinking water supply, they may be exposed to the uranium in the water. Radioactive radiation is not the major concern associated with naturally occurring uranium. It is rather the chemical properties of uranium that make it a potential danger to human health. Uranium is proven to have toxic effects with respect to the functioning of the kidneys.

Utvärdering av möjligheten att tillvarata energi ur processvatten : En undersökning gjort vid Olofsfors AB på uppdrag av UMIA AB.

The company Olofsfors AB manufactures drive belts for forest machinery, known as ECO-Tracks, and abrasion-resistant steel and cutting edges for graders, excavators and tractors, known as Bruxite and SharqEdges. Manufacturing these products requires the steel to be heated and molded, then submerged in water and hardened. The water used in the hardening of steel is pumped to the process from pits below the floor and then pumped back to the pit after it?s been used. Since the temperature of this water rises after being used to harden the steel the temperature of the pumping pit needs to be adjusted to maintain its setpoint of 21°C.

Kan markfuktighetskartor användas för att hitta skogsmark med hög bonitet? : ett gis-baserat försök med dtw-index och laserskannad övre höjd

The depth-to-water-index (DTW-index) is derived from digital elevation models (DEM) to map soil wetness, in terms of distance from soil surface to the ground water table. The aim of this GIS based study was to investigate the existence of a relationship between DTW-index and forest site productivity (SP). The belief of such an assumed relationship was based on knowledge that the ground water level is related to site properties that can either promote or impede tree growth. Data primarily comprised rasters of the Krycklan catchment in northern Sweden and depicted DTW-index and a laser scanned vegetation height. The 100th height percentile of each pixel in the vegetation raster was assumed to mirror the top-height, letting it act as a relative measure of SP within a delineated area of equal stand age.

Vattnets väg genom en romersk stad. -Från vattenkastellet till mottagaren.

The purpose of this paper is to make an analysis of the urban Roman water system. I have chosen to work with the system as a general field, not as a case study of a single town. In my opinion such a study would not give a proper and fair view of the subject. Therefore, this paper will discuss the different parts of the system, each one for itself and name examples wherever possible, to give a wide survey of the reality of the Roman water supply system. The aim is to give the reader a clear picture of different solutions used in the time of the early Roman Empire and a good understanding of the subject..

Vad är area? : En studie på lågstadiet om lärares och elevers uppfattningar om area

Begreppet area har visat sig vara svårt att förstå. I de högre åldrarna visar eleverna bristande kunskaper om begreppet i olika mätningar, nationella som internationella. Den här studiens syfte var att ta reda på hur begreppet area behandlas på lågstadiet. Studien är en kvalitativ studie med semistrukturerade intervjuer av både lärare och elever på en lågstadieskola i södra Sverige. Resultatet visar att undervisningen om area börjar redan i årskurs 1 och lärarnas mål är att eleverna ska få en känsla för vad area innebär.

Utsläpp av växthusgaser under islossning i små boreala sjöar

Freshwater ecosystems have long been neglected as an important part of the global carbon cycle. However, research shows that most of the world?s lakes are net-heterotrophic and consequently emitters of greenhouse gases to the atmosphere. In many boreal and north-temperate lakes, most of the yearly emissions usually occur in spring, shortly after ice-thaw. The aim of this study was to quantify the flux of carbon dioxide (CO2) and methane (CH4) in three boreal lakes, during this annual event.

Natura 2000-områden: rättsverkningar i jämförelse med vanliga naturreservat

Syftet med uppsatsen, att utreda de skillnader i rättsverkningar som finns mellan Natura 2000-områden och vanliga naturreservat,har jag uppnått genom att använda mig av traditionell juridisk metod. Genom att jämföra lagtextformuleringar, förarbeten och bakgrund till bestämmelserna om de två områdesskydden har jag funnit att reglerna om Natura 2000-områden har en betydligt större räckvidd än bestämmelserna för vanliga naturreservat. Allehanda verksamheter och åtgärder omfattas av den särskilda tillståndprövning som gäller för ingrepp i Natura 2000-områden, medan vanliga naturreservat har begränsad räckvidd till de ingrepp som stadgas i reservatsföreskrifterna. Jag har även funnit skillnader när det gäller inrättandet och upphävandet av områdesskydd, och resultatet är att EU-kommissionen utövar en stark kontroll vad gäller Natura 2000-områden. Kommissionen kan tvinga medlemsstaterna att inrätta särskilt skyddat område, och om medlemsstaten vill upphäva skyddet måste samråd ske med kommissionen.

Hållbar vattenplanering : en diskussion med utgångspunkt ur fyra bristområden

Billions of children, women and men lack access to safe water supplies, whichputs the affected in both social as well as economic despair. This paper willpresent some of the conclusions leading Non Governmental Organisations suchas the UN has presented recently concerning the terms of sustainability. Much ofit is true and important, but nothing can be done without extended cooperationbetween nations worldwide to find arguments that prevent short-term thinkingand economic wealth on the behalf of future sustainability.With a growing population and an increased competition for fresh water, theworld will soon face a severe shortage of good quality water for irrigation. This isbecause the distributions rarely match the demand, neither in Australia nor inAfrica. Important to notice is the major factor that the degradation of theenvironment is not one country?s problem to solve.

Perspektiv på Personalutköp : En utredning av en alternativ lösning för avslutande av anställning

This essay investigates employee buyouts and does so from a number of different perspectives. Employee buyout is a term that describes a way of ending an employment through an agreement where the employee gets a sum of money in exchange of leaving their employment. Technically it is neither a resignation, since the employee gives up the employment in exchange of money, nor a dismissal since the employer does not have legal grounds for dismissing the employee. Employee buyout is not an illegal way to end an employment, as long as it is the result of a mutual agreement between the employer and the employee. In this essay I investigate and analyze employee buyouts in relation to 7 § in the Swedish employment protection act, and also Swedish employment protection in relation to regulations from EU regarding employment protection.

Industrivatten : ett gestaltningsförslag över det Östra årummet i Gävle

A proposal of a new path from the inner town of Gävle to a small cultural area in the seaside. The thesis contains historical background, analysis over town and the area, and a proposal of a new shape for the postindustrial area near the stream called Gavleån. .

Föroreningstransport i grundvatten : En modelljämförelse

This thesis compares different methods for risk assessment of a creosote contaminated site in Vansbro, Dalarna. In a complementary study the importance of using representative data for calibration and validation of stationary groundwater models is discussed. The time dependency between surface water levels and groundwater levels on the site in Vansbro is evaluated by step response analysis. The results show that the groundwater levels reflect only long-term variation in the surface water levels. Hence the use of such long-term means for calibration and validation of the stationary groundwater models is the only theoretically defendable alternative.As a first step in the comparison of risk assessment methods the degree of contamination is evaluated on the basis of generic guideline values for contaminated soils, developed by the Swedish Environmental Protection Agency.

Uttorkning av lera : Orsaker och följder

When building a house or similar the stress on the ground increases and deformations can arise. The deformations create a foundation that the building is not constructed for and damages on the building arise. The increased stress on the ground can be derived back to the building, but it is possible that the increased stress may well derive from different sources such as other buildings or trees.       The building is an older property, built in the late 19th century alternatively early 20th century, and is today used for rental housing and has suffered severe damages due to subsidence. The goal of the thesis is to find possible causes for these subsidences. The thesis was executed as a combination between literature- and casestudie. After careful studies it has been found that a probable cause for these subsidences is trees. Through field- and lab studies it has been found that the trees has effected the ground through there accumulation of water.
