Älmhults köping 1901 - 1970 : Från räls till IKEA

In the beginning of the 1860s, an important railway was built between Malmö and Stockholm. The railway became one of the most important projects that would influence the entire southern Sweden. The railway line was located to areas outside the ordinary routes and a number of communities were built up along its way.Älmhult was one of the communities that was built up due to the railway. In the beginning there were only a few farms and a station, but a community developed and the village grew. In 1901 the village became a small market town, which was an important event.

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.

Inventering av värmelager för kraftvärmesystem

When a combined heat and power plant produces heat and power it often faces a deficit of heat load during the summer or other periods of time. This heat is often unnecessarily cooled away or the power production has to be reduced or shut off. If it is possible to store heat from periods with low heat demand to periods with high heat demand one can get many benefits. Among these benefits are: increased power production, decreased operation with partial load, uniformly distributed load.To be able to store heat in situations like this long-term thermal heat storages are needed. In this thesis five different types of stores are presented: rock cavern storage, tank storage, pit water storage, borehole storage and aquifer storage.

Brytpunkten mellan två platser : gemenskap, miljö och identitet från S:a Maria sjukhus till Maria Park

The result of a short field work done in Maria Park, a place situated in the north of Helsingborg city. A comparative work, using the old S:a Maria and Maria Park. The same place, once a mental hospital, and now, at the time of the paper being written, it's a richer residential district. Is there anything left of the old mental hospital in the new community and the residents identities?.

Käppalaverkets nuvarande och framtida rötningskapacitet : en studie i labskala

Käppala wastewater treatment plant situated on the island of Lidingö northeast of Stockholm is running a project during 2004 and 2005 with the purpose to map out the capacity of anaerobic digestion in the digesters that treat primary and excess sludge. The purpose of this thesis work, which is part of that project, was to characterize the present anaerobic digestion process and to investigate its capacity to treat other organic wastes such as restaurant waste and waste from water works. To decide the potential of both methane and biogas production from different substrates batch laboratory tests were carried out. To imitate the anaerobic digestion process at Käppala continuous tests with small scale reactors were carried out. These reactors were later fed with restaurant waste.The batch laboratory tests showed that primary sludge had a potential biogas and methane production of 0,62 and 0,35 Ndm3/g VS respectively after 40 days of digestion.

Hur den nya revisionsstandarden upplevs av revisorer och företag - en fallstudie av Öhrlings Price Water House Coopers samt E.ON och Vattenfall

1 januari, 2004 infördes den nya revisionsstandarden (RS) som är en översättning av ISA, med hänsyn tagen till svensk lagstiftning. RS innebär flertalet nyheter vid genomförandet av revision. Bland annat har revisorns roll förändrats genom att revisorn numera skall granska och uttala sig om fler förhållanden än tidigare.Syftet med denna uppsats är att redogöra för revisorers och företagares syn på införandet av revisionsstandarden. Detta görs i form av en fallstudie med koncentration på tre utvalda RS (RS 402, 501, 570). Öhrlings Price Water House Coopers är representant för revisionsperspektivet och Vattenfall samt E.ON är representanter för företagsperspektivet.

WC-spolning med regnvatten

Idag spolar den stora majoriteten av alla invånare i Sverige med dricksvattnen i toaletten. Spolning med regnvatten i WC är något som på flera håll i världen används flitigt främst i områden med någon slags vattenbrist. Men i Sverige har regnanvändande anläggningars popularitet inte riktigt slagit igenom ännu. Orsaken till detta kan härledas till flera faktorer. De viktigaste och de som påverkar mest är; den goda tillgången och således låga priset på dricksvatten i Sverige, samt begränsad konkurrens bland företag och återförsäljare vilket ger ett högt investeringspris på regnanvändande anläggningar för konsumenten. Fokus i detta examensarbete ligger på att göra en grundläggande analys av regnvatten och möjligheterna att genom en regnanvändande anläggning kunna använda regnvatten istället för dricksvatten för att spola i toaletten med. Tillvägagångssättet har varit att genom en studie av olika källor sammanställa information relevant till ämnet regnvatten och regnvattenanvändning till WCspolning, följt av en analys och jämförelse av hur ekonomiskt hållbar en regnanvändande anläggning i ett standardhus beläget i Malmö är, i förhållande till samma standardhus med en traditionell dricksvattenförsörjning för WC-spolning. Resultatet av analysen visar tydligt att en regnvattenanvändande anläggning i fallet med standardhuset i dagsläget inte går att rättfärdiga ur ekonomisk synpunkt, men även att det finns möjlighet till en realistisk ekonomisk förtjänst i andra byggnader eller i framtiden..

Kraven på ägare till minireningsverk skiljer sig åt mellan olika kommuner

Discharge of inadequately treated waste water containing nutrients such as phosphorus and nitrogen as well as organic matter and bacteria is associated with a risk of eutrophication and contamination. The Swedish government has decided upon several Environmental Quality Objectives aiming to reduce the emissions of nutrients to water bodies.In Sweden, there are between 675 000 to 1 000 000 on-site sewage systems. Recent studies have shown that the function of small sewage treatment plants is in many cases insufficient. To prevent this regular service and supervision by a professional is needed. The focus of this study are small sewage treatment plants which use a technique where mechanical, chemical and/or biological reduction of pollutants is being used in the same facility to reduce nutrients in household wastewater.The aim of the study is to investigate how different municipalities ensure that small sewage treatment plants fulfill the requirements and reduce pollutants as efficient as the manufacturers claim.

Markberedningens betydelse och egenkontroll för markberedning

The purpose of this report is to make an evaluation of the self-monitoring for scarification which Stora Enso is using and this study deals with the effects and importance of scarification. A comparison is made in this study with the purpose to highlight any differences between some of the leading forestry companies and significant forest organizations in Sweden. The companies represented in this report are Korsnäs, Mellanskog, SCA, Sveaskog and Södra. In the beginning of this study an interview form was set up together with Daniel Forsberg at Stora Enso. Stora Enso is the head object of this report and seven interviews were made within that company. At the other companies only three interviews were made within each one, with an exception to Mellanskog who wished four.

Miljömål 17: Hållbar konsumtion : Ett försök att integrera den svenska konsumtionens globala miljöpåverkan med miljömålssystemet

Environmental objective 17: Sustainable consumption - An attempt to integrate the global impact of the Swedish consumption with the environmental objectives system The aim of this report was to integrate the global impact of the Swedish consumption withthe environmental objectives system through presenting a suggestion for a seventeenth environmental objective ? Sustainable consumption. How the Swedish consumption pressures the global environment and methods to measure the affects was investigated. The pressure was divided into five main fields: climate, air, water, land and chemicals. The impacton humans and the biodiversity was also discussed, as well as differences between how men and women affect the environment and get affected when the environment changes.

På färd genom glömda landskap : Rumslig analys av bronsåldersbygden i Mönsterås

This paper deals with the relations between landscape rooms and monuments in an area north of Mönsterås in Kalmar län. After archaeological excavations had been carried out in the area 1991, an article promote it to the ?Bronze Age district of Mönsterås? (Källström 1993). There are two main problems that I deal with in this paper. First: The relations between the natural places and the monuments or memorials.

Grundvattenmodellering i Badelundaåsen

Over an extended period of time there have been plans to establish a shared facility in Lennheden to extract groundwater from the Badelunda esker to provide drinking water for the cities of Borlänge and Falun. The city of Falun is dissatisfied with the quality of its drinking water and the city of Borlänge is concerned about the risk of contamination of its existing groundwater supply at its current location. To provide a basis for a decision on this issue, the company Midvatten AB has been commissioned to perform hydrogeological investigations in the area of Lennheden.The purpose of this thesis is to design a functional groundwater model of the area between Lennheden, place of planned extraction, and Övre Tjärna, place of existing extraction, to get a better understanding of the groundwater situation in the area. A groundwater model enables simulations of different scenarios in risk assessment and contaminant transport. The aim of the thesis is that the model can be used as an aid in Midvatten?s investigations in Lennheden and that it also can be used in future projects in the area.The model has been made in Processing Modflow 5.3 and encompasses an area of 19,5 × 11 km along the Badelunda esker and the river Dalälven between Djurmo and Frostbrunnsdalen.

Pre-spawning habitat selection of subarctic brown trout (Salmo trutta L.) in the river Vindelälven, Sweden

Habitat selection of migratory brown trout at the upper reaches of River Vindelälven, wasstudied in September during the pre-spawning period. The fish migrate from down- orupriver lakes for spawning in the river and data was collected by habitat mapping andradio-telemetry. Habitat selection of fish was analysed with preference curves andstatistical modelling, using the physical variables; depth, stream velocity and streambedsubstrate. Preference curves were derived by comparing fish habitat use with their nearbyavailable environment while the statistical modelling aimed to answer three main questions.1) Do the trout have a specific preference of depth, water velocity and streambed substrate?2) Is there any difference in habitat selection between sexes? 3) Is there a shift in habitatselection over time? The preference curves indicated that trout favored water depths of 1-2m, velocity compositions characterized as glides (c.

Fisk- och fågelpredations påverkan på den bentiska makroevertebratfaunans sammansättning under tidig vår i Tåkern

Predation is one of many factors that form the structure of the macroinvertebrate community in lakes, wetlands and watercourses. Earlier studies lack an examination concerning how fish- and waterfowl predation affect macroinvertebrates during shorter periods in the spring. I performed an exclosure study in the shallow eutrophic Lake Tåkern which is located in the western part of Östergötland County, Sweden. The experiment was performed during a three week period (1-21 April 2012) when the water temperature was low and the density of migrating diving ducks was high. The experimental cages used included three out of four different treatments; general predation (open cages), bird exclusion (net with mesh size 90*45mm) and no predation (net with mesh size 1*1mm).
