Societetsparken i Norrtälje : nulägesanalys och utvecklingsförslag

The short term effect of phosphorus in sewage sludge was investigated to establish howmuch of this a farmer can grant him- or herself, if using sewage sludge as a phosphorusfertilizer. Possible differences in plant availability between sludge phosphorus precipitatedby iron, aluminum or calcium integrations were studied in a sandy soil at two pH levels.The sludges were analyzed using pot and incubation trials. As the intention was to investigategrowth limitation due to phosphorus deficiency, a soil with low phosphorus supplywas chosen as well as a low phosphorus application rate. Sludge corresponding to 12kg phosphorus per hectare was applied. Treatments fertilized by sludge were compared totreatments where 0, 6 and 12 kg phosphorus per hectare from mineral fertilizer was applied.Every treatment was replicated six times.

Återföring av växtnäringsämnen från avloppsvatten till åkermark : en bedömning av intresset för nya näringsrika produkter

Sewage sludge contains plant nutrients and has earlier been utilised as fertilizer to cropland. Unfortunately not only plant nutrients but also heavy metals, pathogens and organic contaminants tend to accumulate in sludge. The suitability to use sewage sludge in agriculture has therefore been subject to several discussions over the years. The Swedish food industry does no longer accept sludge as fertiliser for Swedish producers. In 1999 the Swedish parliament accepted several objectives for environmental protection. In order to prevent environmental pollution and further exploitation of the earth crust, one of these objectives confirm that phosphorous from sewage shall be recirculated to arable land.

PPM - Passivt Placerande för Många : En analytisk studie av premiepensionsspararnas avsaknad av strategier för fondval

Introduction: In 1998, the pension system was changed and the so called PPM system was introduced. The PPM system is partly fund-based, partly distribution-based. There are approximately 700 different investment funds to choose between, at a maximum five for each individual. For persons who are not familiar with the financial market, the choice might be difficult. The lions? part of the investors do not seem to have an active strategy.

Kortsiktig fosforeffekt av avloppsslam : krukförsök i växthus där järn-, aluminium- respektive kalkfällt slam använts som fosforgödselmedel

Begreppet individ, hos Leibniz och Spinoza, sa?som singula?rt och del i va?rldens ma?ngfald

This thesis deals with the concepts of individual and individuation as defined by Leibniz and Spinoza. I go through the use and definition of the concept of individual in four stages.First I discuss the individual as conceived by Spinoza as a relation formed by a composition of parts and the individual as conceived by Leibniz as a complete notion consisting of all the events in the life of a subject.Next is the roll of perception in Leibniz discussed, likewise individuation through different perception with varying distinctness, and the affinity of perception with affection.The discussions concerning the individual concludes in a section about the essence of the individual as being the desire of the individual. In the last stage, I discuss the multitude as being an own individual..

Omedelbart omhändertagande : En studie om interimistiska beslut inom LVU med hänsyn till barnets bästa

This study analyzes the court of appeals work on judging immediate care (6 § LVU) by the child´s best from 10 court cases. This study has been reviewing 10 court cases and reviewing the court of appeals applicable laws in their decisions on interlocutory order within LVU. The material than have been analyzed consists of immediate care of children, and the concept of the best interests derived from the UN Convention on the Rights of the Child.The legal sanctions includes when a state signs a convention, which Sweden has. This means that Sweden is at their disposal to offer all children within its territorial limits, up to 18 years may take part of the rights set down in the Convention of the Rights of the Child. This means that all decisions relating to the individual child, should always be taken with respect to the best interest of the child, when a child for varoius reasons end up in a lawsiut.The concept of the best interest of the child are vague and abstract because it is not clearly defined.

Optimerad hygienisering vid kompostering av avloppsslam

The aim of this study was to in laboratory experiments investigate how addition of urea, ECOX and structural materials can optimize sanitization during composting of sewage sludge. Today we strive for a sustainable society and the importance of closing the nutrient loop increases. It has therefore become even more important to safely reuse plant nutrients from human excreta to agricultural land. Partly because it increases the sustainability of society as the world's supply of many nutrients are finite, partly because it promotes human health, both by reducing disease transmission and by increasing Agricultural production. An untapped resource such as sewage sludge that is rich in nutrients and humus-forming materials could replace parts of the commercial fertilizers used in Sweden today. owever, sewage sludge contains undesirable substances such as heavy metals and drug residues, and pathogenic microorganisms.

Från Bomull till Byxor Livscykel Inventering och Ansvarsfullt Företagande En MFS i Södra Indien

A growing number of companies realise that to achieve their environmental goals and satisfy stakeholder expectations, they need to look beyond their own facilities and to involve their suppliers in environmental initiatives. A life cycle approach means that the production system should be optimised as whole, across national boarders and individual organisations taking part all the way from extraction to disposal. This study is a Life Cycle Inventory of resources used when producing a piece of cotton garment and the method is based on the standardisation series of ISO 14040-43. The area of study, Tamil Nadu the most southern state of India, accounts for more than 90% of India?s knitwear exports to Western Europe.

Sammanställning och utvärdering av små avloppsanläggningar utifrån tillförlitligheten hos angivna reningsgrader

The private sewage systems in Sweden releases around 600 tons of phosphorus per year, compared to about 350 tons from municipal sewage treatment plants, and they account for approximately 21% of the total anthropogenic discharge of phosphorus into Swedish waters. About 40% of Sweden's nearly 1 million private sewage systems are inferior with respect to emissions to surface and groundwater. The technology of small sewage plants is under development and knowledge of treatment effects for different solutions is poorly consolidated. Municipal authorities lack resources to keep up with the technologic development and assess the reliability of the treatment performances that suppliers report for their products. The thesis aims to conduct a market review and evaluation of wholly or partially prefabricated small sewage plants, to make it easier for municipalities and property owners to assess different technical solutions. The goal is a compilation of the products on the market, evaluated on the basis of the reliability of specified degrees of reduction.Information on sampling procedures and test results were collected through a questionnaire to all active suppliers and the responses were then used to classify the products.

Inflytande i teori och praktik : En kvalitativ maktanalys över arbetet med individuella planer enligt LSS

People with certain types of disabilities have the legal right to ask for an individual plan. The idea is that the plan should be a tool for the disabled to get more power and influence over the planned actions that involves their lives. The aim of this thesis was to study the individual circumstances of interpersonal power and influence in the work of individual plans. The study was done with a qualitative approach, where three executing officers and three individuals were interviewed. The results show that the conditions for the individual?s influence are far more complicated than at first glance.

Äldres erfarenheter av aktiviteter i ett socialt sammanhang. En narrativ studie om den åldrande människan

There is no general aging process therefore should health efforts directed at elderly population based on each individual as a unique person with specific needs. When aging becomes a fact not generally decrease the lust and the desire to be active but it is perhaps more about the body's ability to keep up on what the head wants. Therefore the range of activities towards the elderly population requires some adjustment that can partly be achieved by taking some of the older people?s experiences. The purpose of this study was that by the older people?s experiences of organized activities in a social context to illustrate how they perceive their participation.

Överlevnadsanalys och avyttringsorsaker - för ackordhäststiftelsens hästar 1967-2012

Few scientific studies have studied the subject of longevity among horses over a longer period of time. The knowledge about the Swedish riding school horse population concerning injuries and diseases is insufficient. Generally speaking, riding school horses in Sweden have a more undiversified way to work and work more hours in the arena compared to privately owned horses that have more variety in their possible use. Statistical data from the insurance company Agria have shown that horses in riding schools and education facilities have 22 % higher risk to use their veterinary insurance and 79 % higher risk to be put down and use their life insurance, compared to horses in private care. To create an increased understanding for longevity is it important to have knowledge about the different causes of culling. The aim with this study is to increase the knowledge and enable problem solving within the subject of longevity, median length of life and causes of death.

Utvärdering av olika sätt att hantera avloppsslam i Värmdö

Important issues for the local authorities are what to do with the sludge produced insewagetreatment plants. The tax for landfill leads to higher costs with 250 SEK/ton. On the 31December 2004 it will be forbidden to landfill sludge.In Sweden the yearly production of sludge is 240 000 tons, counted as DS. The phosphorouscontent is 3 % in sludge. The total yearly production of sludge gives 6000 tons of phosphorous.

Habitus - ett arbete om klass

 Why is it that we still live in a society where an individual's social background plays such a big part in their chances of reaching a higher education? Despite the numerous educational policy reforms, especially in Sweden, it still seems that an individual's career choices are pretty much related to what kind of social class they grew up in. Sociologist Pierre Bourdieu claimed that social class is reproduced in the school system, and that students from the lower classes are much less likely to reach a further education than students from the middle or upper classes due to injustice in the school system. One thing that plays a big part in this "Catch-22" situation is the concept that Bourdieu calls habitus. Habitus could be explained as an individual's taste, knowledge, ability to master the spoken language, etc. Your habitus is manifested in the choices you make, the music you listen to, how you dress and the way you speak, and it determines your relation to the education system and life in general. As part of my essay, I wanted to interview students from lower or working class at my school, Konstfack, to see if they have had any negative or positive experiences from their encounter with a higher education. And if so, could they be linked directly to their social background? As a reaction to my own and my interviewees? experiences and frustration, I use the concept of habitus in my practical work.

Rening av avloppsvatten från biltvättar med filter av torv och inblandad kolaska : en utvärdering av effektivitet och avfallshantering ur ett miljöperspektiv

Filtermaterial av 75 % torv och 25 % kolaska har använts under 2 respektive 4 år för rening av avloppsvatten från två biltvättar. Jämförelse med Kristianstads kommuns riktvärden för avloppsvatten från fordonstvättar visar att filtren fungerat. För avfallsklassning krävs kunskap om innehåll av miljöfarliga ämnen i produkter som använts i tvätthallarna. I brist på kunskap om innehåll av ej analyserade miljöfarliga ämnen i filtren anses förbränning vara ett bra omhändertagande ur miljösynpunkt, då energi och aska återvinns..
