Nitrat i dricksvatten : jämförelse av nitrathalter, mellan åren 1975 och 2005
Ronneby Miljö- och hälsoskyddskontor ville genom undersökningen få information om nitrathalter ienskilda dricksvattenbrunnar inom kommunen, med bakgrund av den nya miljökvalitetsnormen.Riktvärdet för nitrat är 50 mg/l. Halter som överstiger detta bör inte ges till barn under ett års ålder pågrund av risk för methemoglobinemi. Jämförelsen skulle ske mellan områden präglade av jordbrukrespektive skogsbruk, samt mellan grävda och borrade brunnar. Jämförelsen skulle även ske över tiden,mellan 1975-1990 till 2005. Urvalet av provtagningspunkter baserades på en sammanställning frånbefintligt arkiv samt efter en annons i dagspressen.
Potentiell fosforfrigörelse från sedimentet i Bornsjön, sydvästra Stockholm : The potential leakage of phosphorus from sediment in Lake Bornsjön, south western Stockholm
Lake Bornsjön is situated 30 km southwest of Stockholm in a rift valley lake and consist three basins outstretched in northwest-southeast direction. The surface area is 6,7 km2 with a maximum depth of 18,3 meters, a mean depth of 9,8 meters and a retention time of the water of 6,5 years. The drainage area is 42 km2 and consists mainly of arable land (ca 1000 ha) and productive forestry land (2500 ha), but in the drainage area there are also restored and fairly newly constructed wetlands.Today the Stockholm area receives its drinking water from Lake Mälaren, but if there would be any pollution of this source, Lake Bornsjön would act as the water source. The area surrounding the lake was bought already in 1899 by Stockholm Stad for protection of the lake and was taken over 1993 by Stockholm Vatten AB. It has been a water protection area from 1988 and it was also accepted as a nature reserve in 1995.

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.
Psykisk ohälsa hos barn : Hemmets resurser i förebyggande syfte
During the later part of the 20th century the amount of children and adolescents in Sweden who reported psychosomatic illness have greatly increased. The main reason is estimated to relate to weak resources in school and school healthcare. Increased resources do not always have to encompass investments for school and school healthcare. Other resources play an important part as well. A child?s domestic situation serves as one of those resources where fundamental knowledge and values are set.
Investigating the bond between research dogs and a familiar person and validation of the Ainsworth's Strange Situation Procedure (ASSP)
In the dog-human relationship humans are the ones who provide the dog with safety and comfort. Ainsworth's Strange Situation Procedure (ASSP), which was originally developed in humans to study the relationship between mothers and infants, has been modified to investigate the emotional bond research dogs have to a familiar person. Twelve research dogs were tested to investigate whether the dogs performed any behaviours indicating a secure-base effect, such as more exploration and play in the presence of a familiar person and proximity-seeking behaviours when this person is or has been absent. In the ASSP the dog enters a room with a familiar person, is introduced to a stranger, is left alone for a short period of time and experiences moments of separation and reunion. A second variation of the ASSP was added where the familiar person was replaced by another, to the dog, unfamiliar person.
En intervjustudie om lek och samspel hos elever med Asperger syndrom : ?Jag är ganska unik?
Studiens syfte är att undersöka lek och samspel hos elever med diagnosen Asperger syndrom eller högfungerande autism genom att ta del av deras egna upplevelser av detta. Hur beskriver dessa elever sin lek under förskole- och skoltid? Hur beskriver de sitt samspel med andra? Vilka ställningstaganden gör eleverna för att delta eller icke delta i lekar?I litteraturgenomgången belyses olika begrepp och aspekter som är relevanta för studien såsom lekens betydelse för ett barns utveckling och lärande. Här presenteras också autismspektrumstörningar och vad dessa funktionshinder kan medföra för konsekvenser för barnet när det gäller lek och samspel. Svårigheter som gäller ömsesidig social interaktion, ömsesidig verbal och icke-verbal kommunikation samt fantasi och alla dessa områden är viktiga förutsättningar för lek och samspel.Den metodansats jag är inspirerad av är hermeneutiken.
Omvärldsbevakning på bibliotek
The purpose of this article is to investigate how and from which sources librarians collect information on their profession with respect to factors that are important for their work. In order to achieve this goal, a questionnaire-based survey will be conducted at three medium-sized central-public-libraries in southern Sweden. Using this survey, I wish to answer the following four questions: To what extent do librarians acquaint themselves with changes and developments within regional and cultural policy arenas important to their work? To what extent do librarians acquaint themselves with information using conferences and library debates that are focussed on changes and developments relevant to their work? Do librarians consider that they have enough time within the limits of their work hours to follow developments within the librarian profession, for example with respect to developments within information technology, and how would they appraise the future demand for information technology-based services at the library? From which source(s) do librarians collect information relevant to their work? The theoretical basis of this paper can be compared to a radar as it scans subjects-of-interest to the organization in the field of business intelligence. This investigation uses a quantitative method, with data collected via a survey consisting of 13 questions.
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.
Miljö i fokus - En studie av de bakomliggande drivkrafterna för den ökade miljömedvetenheten inom svensk kemiindustri
BACKGROUND & During the last century, the Swedish chemical industry has developedPROBLEM: considerably in regard to respecting the environment. Following various discharges and pollutions during the first half of the 20th century, environmental concepts such as CSR, Responsible Care and REACH have developed in order to improve the situation. Today, environmental issues play a central role in the society, but what are the reasons behind this increased environmental commitment? PURPOSE & The purpose of this thesis paper is to study the driving forces behindDELIMITATIONS: the increased environmental awareness in companies. Is this mainly due to stricter legislations, or do factors like pressure from the general public, the industry or customers play a more vital role? Furthermore, do economic incentives exist, that make it interesting for companies to invest in environmental awareness? Since the chemical industry spans over a wide spectrum in regard to environmental issues, this paper will focus on a specific area of the industry.
Faktorer som påverkar sjuksköterskans användande av omvårdnadsplaner : en litteraturstudie
The purpose is to illustrate the phenomenon of self-harm from a social psychological and sociological perspective. The purpose is furthermore to examine the role social relationships play in the individuals´ self- imagine and what role does identification play for anyone who harm themselves? We want to examine in what way social relationships are important and how they function for individuals who harm themselves, both once they have started to harm themselves, and if the relationships in any part caused the cutting to begin with.Questions:How do individuals shape their identity based on self- harm? Which self-image do individuals have who self-harm? Is there anything in the person's previous social relationships that have caused them to begin to hurt themselves?Method:In this paper we have analyzed five autobiographies. We have used open coding from grounded theory as analytical method and subject positions based on discourse analysis.Theory:We have used the Cooley concepts looking glass self, Foucault's theory of power, Giddens' concept of ontological security and existential anxiety.Results and Analysis:We found six different categories that we thought were central. These were negative self-image, guilt, lack of family support, negative experiences of others' views, the protective identity as self- harmer and insecure social relationships in school.Conclusion:The self-harming is a very complex behavior.
Dockor, bilar och rutschkanor : Leksakers genusbetydelse i bilderböcker
This essay will focus on the significance of gender in toys´ portrayed in children books for the age 3-5years. The aim for the essay, partly, is to highlight how gender stereotypes can come forth and affect children through the way toys are illustrated within children?s books. The essay will address books from two different time periods, the first period being the 40-50- 60's and the other being the 00´s. The questions to be addressed in this essay is; what type of toys? children play with in the books used in the analysis, and if a change can be detected between the different time periods in terms of gender awareness in what type of toys are presented in the books.The main method used in this essay is an iconological image analysis in which the first step is mapping, other methods used is analysis and interpretation.
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..
