Återvinning av näringsämnen från hushållsspillvatten med omvänd osmos
Hammarby Sjöstad is a new district in Stockholm with high environmental standard. Stockholm Water Company evaluates a local wastewater treatment plant with cutting edge technology. The first step is an experimental treatment plant (Sjöstadsverket) with four parallel lines of treatment, each with a capacity to treat wastewater from 150 persons. Within the membrane technology subproject the possibility of using reverse osmosis (usually called RO) to regain nutrients is examined.Reverse osmosis separates the incoming water in a clean permeate and a concentrate that, as the name indicates, is a more concentrated version of the incoming water. Using this method in wastewater treatment, a solution high in nutrients can be obtained without the use of chemical precipitation agent and with no production of sludge.

This places very high demands on the technology used and it is important that it function and develops to meet current and future growing needs.
Effektivisering av ekologisk dagvattenhantering i stadsmiljö
I Jönköping har problemet med översvämningar, erosion och materialtransport varit ett stort problem i Strömsbergsbäcken i Jönköpings kommun. Detta har tillviss del orsakats av ett ökat dagvattenutsläpp i bäcken, vilket skapar kraftigaflödestoppar då den ursprungliga fåran inte är ?dimensionerad? för den ökadevattenmängden. Syftet med arbetet är att effektivisera ekologisk dagvattenhantering i stadsmiljö med högt dagvattenutsläpp. Målet med arbetet är i sin tur att framställa underlag för hur ekologisk dagvattenhantering i stadsmiljö kan genomföras och att rapporten skall kunna ge värdefull kunskap till liknande sammanhang.
Argument för prissättning av skogsfastigheter
The world economy of today is in an extensive financial crisis which has lead to the fact that people seek well placed investments and securing of capital, something that by many people can be found in forest investment. The price of forest estates has increased with 90 % during the last 5 years and marketing polls indicate a positive belief in the future among forest owners. The development of timber prices has not increased to the same extent as the forest property prices which implies that the property price not only reflect the yield value from the forest but also that the lumber value does not have such a meaningful role in the pricing of forest properties as proven earlier. This fact means that forest owners either invest their capital in forest in a speculative point of view or that the purchasers of forest properties invests in non monetary benefits that lacks a direct yield value. The purpose with this degree thesis is to increase the understanding of the pricing of forest properties with focus on the above mentioned fact.
Produktivitetsförbättringar : - förhöjning av produktiviteten vid mekanisk verkstad genom förkortade transportsträckor och standardiserad bearbetning
The aim of this project has been to raise the production efficiency of Daliff Precision Engineering through reduced transportation time and a more standardized manufacturing process. The problem has upraised because of a big and diversified product flora without any standard products and with just small batches ordered. The report also tries to show the work procedure with general analytical methods and be an example of how a similar problem can be resolved. The transportation time is being proposed to be reduced through a change in the layout of the factory. By moving a few manual machines, dispatch and burring to more efficient locations, the total transportation time will be reduced by 55 %.
Utvärdering av fosforläckageefter stallgödsling med hjälp av lysimeterteknik : Evaluation of phosphorus leaching aftermanure application using lysimeter techniques
Based on laboratory studies with lysimeters, the concentrations of dissolved reactive phosphorus(DRP) and particulate phosphorus, which is the main part of other P (OVRP), has been studied inpercolating water. The experiment was conducted through irrigation of small soil columnscontaining clay topsoil from an experimental field in Västergötland. Three rain simulations wereconsecutively performed. DRP concentrations in the percolating water ranged between 0.2 - 0.3mg·Lclearly related to the phosphorus concentration in the soil, measured in a soil extract ofammonium lactate (P-AL). Concentrations of OVRP were relatively low and ranged between0.12 and 0.16 mg·Lwas not proven and the experiment may reflect how a relatively slow percolation of water mayrelease DRP.
Funktionella tester och utvärdering av skadepreventiv träning hos kvinnliga fotbollsspelare - en interventionsstudie
The exclusion of visually impaired from the information flow presented to us through signs was what led me into this project. With a growing amount of information being presented to us on signs and digital information surface the need of communicating this information in a way that could be read by visually impaired is evident. Looking into different ways of communication, my goal was to create something that filled the need of the visually impaired without branding them as disabled. Having a close relative with bad eyesight is became evident on how much it limited her in her everyday life, not being able to navigate herself without the support of her husband. Through interviews with her and others with varying diagnoses I reached an insight in their situation. To my surprise they still favored a visual form of communication before an auditory or tactile form, because it?s easy to survey and quick to interpret.
Fysiologi och beteende hos golden retriever i hemmiljö och under en testsituation
To fit into our society the dogs of today need a good mentality. To investigate their mentalitydifferent behavior tests have been developed. The tests are useful tools in the selection ofbreeding animals as well as for working and companion dogs. To counter the demand for atest that could be suited for all kind of dogs, regardless of their future function, the mentalitytest Beteende- och personlighetsbeskrivning hund (BPH) was developed. BPH consists ofseven subtests that expose dogs to various situations that can be found in everyday life, suchas meeting an unfamiliar person, sudden noises and suddenly appearing objects.The aim of this study was to find out if there are differences in physiological values betweenindividuals, validate the behavior observations during BPH and get aware of how the dogsexperience the situation.

Considering that the current technology is constantly improving, it becomes increasingly important to have an efficient logistics in a company to maintain profitability while achieving a competitive business. Efficient logistics may be accomplished by improving the internal materials handling. In this thesis the internal material handling of steel frames has been studied at a factory in Vaggeryd. The goal of this study is to investigate the problems that exist with the current production flow of products and provide suggestions on how it can be developed to reduce unnecessary handling and movement.The study has a deductive approach where the authors has been using literature studies parallel with empirical analyzes conducted at a company to achieve the purpose of the study. Documentation from the company and interviews with staff and observations form the basis for the data collection carried out.
Att investera i toppen av en högkonjunktur : Ett fenomen i svensk börshistoria
Bakgrund: Åren 86-97 kännetecknas som en period med flera stora reformer och en svensk konjunktur som nådde sin botten med tre år i följd av negativ BNP-tillväxt. Påtagligt var även reaktionen från Stockholmsbörsen som i samband med lågkonjunkturen upplevde en kraftig nedgång. Vad drev då denna avkastningsutveckling, vinsterna eller värderingarna av dessa? Hur såg sambandet ut mellan konjunktur, bolagsvinster, vinstvärderingar och börsutveckling för perioden?Syfte: Syftet med denna uppsats, på uppdrag av Melker Schörling AB, är att studera avkastningsutveckling, bolagsvinster och P/E-multiplar över en konjunkturcykel för att analysera till vilken grad multipelexpansion/kontraktion kontra vinsttillväxt drivit avkastningen för olika branscher på Stockholmsbörsen.I ett andra skede utreds huruvida prognoser för P/E-tal och branschvinster på Stockholmsbörsen korrelerat med konjunkturen samt även hur EBITDA- och vinstmarginaler inverkat på aktievärderingar under tidsperioden. Utifrån studiens resultat kommer eventuella lärdomar kopplas till dagens konjunkturella situation.Genomförande: Insamlat datamaterial i form av siffror och nyckeltal utgår från Affärsvärldens tidsskrifter och årsböcker med början 1986 och slut 1997.
??Finns det ett samband mellan graden av periodiseringar och inflationsjusterade skattade framtida rörelseresultat? : - Empirisk studie av den europeiska aktiemarknaden.
In line with Sloan (1996) but on European data (STOXX 600) we are investigating whether stock prices reflect information about future earnings contained in the accrual and cash flow components. The extent to which current earnings performance persists into the future earnings performance is shown to depend on the relative magnitudes of the cash and accrual components of current earnings. Moreover, we still find a significant positive excess return (Jensen?s alpha and size-adjusted return) by replicating Sloans (1996) hedge portfolio by taking a long position in the stock of firms reporting relatively low levels of accruals and a short position in the stock of firms reporting relatively high levels of accruals. However, we find no evidence of negative excess returns for companies with relatively high accruals, this somewhat lower the total excess returns for all the portfolios.

Utveckling av en teoretisk elektrokemisk apparatur för vattentransport i hjärnvävnad
Varje år i Sverige sker ca 24 000 skallskador på grund av yttre trauma och 30 000 strokeskador. Ett betydande antal får sekundära skador på grund av den ökade vattenhalten kring den skadade hjärnvävnaden. Föreslagen metod är att inducera vattenflöde från skadad till frisk vävnad baserat på teorin om elektroosmotiskt flöde. Teorin bakom elektroosmotiskt flöde är att ett flöde induceras då en spänning läggs över ett medium. Elektroosmotiskt flöde tillämpas i industrin och kallas då electro-osmotic dewatering (EOD).
Offentliga rum och utsuddade identitetsbegrepp : en resa mellan det virtuella och det fysisika i tid och otid
Trough a literature study based on both philosophic and objective fact this essay is taking off in the meaning of public space. It investigates how the information society and its virtual world are affecting the idea and use of public space in the city. The city and the actual world have developed from the traditional meeting between people while the virtual world is based on flows of information. The information flow has expanded through the Information and Communication Technique (ICT). ICT covers among others Internet, mobile phones and computers.
Syringomyeli hos hund
The canine population has during it?s time with humans gone through at least 2 major genetic bottlenecks, the first when it was separated from the wolf, and the second when it was divided into different breeds. Among other things, this has lead to the accumulation of unwanted genes, such as genes causing disease in dogs. One such inherited disease is syringomyelia, which has proven to be more common than expected, especially in certain smaller breeds such as the Cavalier King Charles Spaniel. Syringomyelia in dogs is often a secondary condition caused by the malformation called occipital hypoplasia.
