Simulering av COD-fraktioner i en aktivslamanläggning vid en sulfatmassafabrik

This thesis work was made for Södra Cell Mörrums bruk in Blekinge. The purpose of the work was to develop a computer model in the simulation program Extend for the removal and balance of organic oxygen consuming substances, measured as COD (Chemical Oxygen Demand), in the new biological treatment plant in the mill. The plant produces two different pulp products, TCF- (Totally Chlorine Free) pulp and ECF- (Elementary Chlorine Free) pulp, for sale. The different bleaching procedures affect the characteristic of the wastewater and thus the effectiveness of the biological treatment plant.In the model that was developed the COD in the wastewater was divided into five different COD-fractions: soluble easily degradable (SS), soluble hardly degradable (SR), soluble inert (SI), particulate inert (XI) and particulate biomass (XB). To create the model FlowMac? was used as a base.

Perceptuell och akustisk bedo?mning av ro?stfunktion hos barn med tonsillhypertrofi : Effekter av kirurgi

In Sweden over 10.000 patients annually, mostly children, undergo tonsillar surgery. The most common surgical method is total removal of the tonsil, tonsillectomy (TE). During the last decade partial tonsil resection, tonsillotomy (TT), has been reintroduced and is associated with lower primary morbidity and less postoperative pain. The aim of the present study was to evaluate if and to what extent 4-5 year old children?s voice function are affected by tonsillar hypertrophy compared to controls and to study the effects of the two surgical techniques on vocal function.

Småvatten då och nu : en förändringsstudie av småvatten i Skåne och deras kväveretentionsförmåga

Wetlands play an important role in the ecosystem. They reduce the impact of flow flux in the drainage area, acts as upholder of biodiversity, as an esthetic and recreational component in the landscape and they have the ability to reduce nutrients such as nitrogen, and help preventing eutrophication in costal areas.The number of wetlands in Scania have, due to the intensified agriculture been reduced to maximize the area suitable for crops.However since the mid 80th the consequences of this has been acknowledged, and many wetlands have been restored.This master?s thesis aim to see what impact this development have had on wetlands in Scania over the last 60 years. And also look at some of those factors important for the efficiency of nitrogen removal in wetlands. During the process a detailed manual for inventories of this sort was created.The material used to execute the inventory of wetlands where aerial photographs over Scania from the 1940th, 1980th and 2000.

DRM - utveckling, konflikter och framtid : konsumenters reaktioner på och företags användande av DRM

With the digital revolution within video games, the need for Digital Rights Management (DRM) has increased significantly, alongside with the increasing problem of copyright pirates. To counter pirates, DRM was created to prevent illegal copying of software, this to ensure that the Distributors received an income for their work. DRM has, since the start of its use, been getting, a lot of bad criticism from the users of the software protected by DRM. The main function of this paper is to describe the creation and development of DRM by analysis of the vision of different groups on this phenomenon. The main questions are as follows, is it possible to define the very reason for why DRM was created and if so, can its development through time be defined too? What differences in opinions are there when it comes to DRM, counting the two major groups of creators, sellers, distributors (referred to as distributors) versus individual users (referred to as consumers)? In what way will the research results suggest that the future DRM will develop?The development has gone from solving puzzles in a handbook to start the game each time the user wants to play, to serial numbers that is needed during the installation of the game.

Stöpt i kulspruteolja en litteratursociologisk studie av den unglitterära tidskriften 40-tal och dess idéklimat.

This masters thesis is a study of the ideas brought forward in the literary magazine 40-tal. The methodology involves the adaptation of a literary sociological perspective where the ideas of the young literary avantgarde in the magazine 40-tal interplays with the established philosophy of the Swedish society during the period 1944-47. The main purpose has been to examine 40-tal as a product of supreme individuality that originates a unique climate of ideas which exceeds the involved collaborators individual writings. I have thereby related my analysis to the Marxist oriented theories of Raymond Williams. This has been done in order to see how the external pressure of the social structure and the market acts together with the internal pressure of keeping up with the times and how this affects the individual authors and the process of creating.

Komjölk och kronisk förstoppning hos barn - En systematisk översiktsartikel

Sahlgrenska Academyat University of GothenburgDepartment of Internal Medicine and Clinical NutritionAbstractTitle: Cow?s milk and chronic constipation in children ? A systematic reviewAuthor: Sara Palm & Anna SvenssonSupervisor: Frode SlindeExaminer: Anna WinkvistProgramme: Dietician study programme, 180/240 ECTSType of paper: Examination paper, 15 hpDate: May 27, 2014Background: Chronic functional constipation is common among children. Up to a third of all who seek a paediatrician suffer from constipation and it is a widespread problem for children in many countries. Lately it has been discussed if cow?s milk can be a cause of the constipation and if it should be considered a delayed hypersensitivity.Objective: The aim of this systematic review is to examine whether there is scientific evidence to recommend a cow?s milk-free diet as a potential treatment in chronically constipated children.Search strategy: The literature searches were performed in the databases Pubmed, Scopus and the Cochrane library, using the search terms cow?s milk, constipation, milk proteins, dairy products, milk hypersensitivity, cow milk and cows milk between March 17th and April 4th 2014.Selection criteria: Randomized controlled trials measuring stool frequency in chronically constipated children on a cow?s milk-free diet were included.

Whole grain wheat : effects of peeling and pearling on chemical composition, taste and colour

The EU-project HEALTHGRAIN has suggested a new definition for whole grain which allows a small part of the grain to be removed during processing. By removing the outer part or the grain the hygienic quality will increase but it is not clear how the taste and colour is affected. So therefore in this study three different debranning methods, peeling, pearling and polishing, which remove the outer parts of the grains have been used on common and durum wheat. The dietary fibre and ash content, as well as germination was analysed in untreated, peeled, pearled and polished grains. The decrease in dietary fibre and ash was higher in grains that had been pearled compared to those that had been peeled or polished.

Markering och risning av basvägar inom slutavverkningstrakter : en intervjustudie hos maskinförare och planerare

In an attempt to prevent ground damage and to reduce harvesting costs, StoraEnso's districts Värmbodal and Fryken, selected a number of final felling areas where the base roads have been marked by planners in the districts. The parties involved in the experiment are mainly planners, harvester operators and forwarder operators. The purpose of this paper is to determine the findings of this trial and to find cost savings or lost revenue. This has been done with a sample of interviews from the involved parties who logged the chosen felling areas. Literature about the interview process has been used to facilitate data collection, interpretation and analysis of the material. If we look at profitability based on assumed income and expenditure, revenue per MWh would be 63 SEK.

Kundtillfredsställelse på en studentnation : en fallstudie på Norrlands nation i Uppsala

The 26th of February 2009 the Swedish government gave a referral to the council of lawregarding the removal of a law concerning mandatory membership at a student union andstudent nation while studying at a university or college in Sweden. This has led to adiscussion amongst the student nations in Uppsala as to how this proposed change will affectthe nations? future operations. Some, including the chairwoman for Kuratorskonventet,Therez Olsson, and the 1Q for Norrland?s student nation, Jon Stridh, have expressed theirworries that this could lead to a decrease in members.

Bacterial contamination of eggshells in deep litter floor systemsand conventional cages in Jordan

This study was carried out in Jordan with the purpose to investigate the bacterial microflora of egg shells from cage systems and from deep litter floor systems. Another aim wasto get a general impression of the hygiene, at farm level, of egg production in Jordan andthe factors affecting it.Eggs from two cage systems and three floor systems were analyzed, regarding bacterialcontamination of the egg shells. Egg samples were taken from the storage room, the eggcradle in the cage system and from the nest and floor in the floor system. To get a generalimpression of the hygiene at the farms, swab tests and air tests were performed. Swab testswere performed with a sterile cotton swab at the same units as the eggs were sampled andair tests were performed by opening petri dishes where the hens were staying.

Hur kan företags val att inte anlita en revisor förklaras? : en studie gjord i efterdyningarna av avskaffandet av revisionsplikten i Sverige den 1 nov 2010

Efter avskaffandet av revisionsplikten för små företag i Sverige, den 1:e november 2010, har många små företag valt att inte anlita en revisor. Den främsta orsaken till detta torde vara kostnaden men eftersom det finns flera fördelar med revision undrar man om det finns andra bakomliggande orsaker. Syftet med denna uppsats är att förklara vilka faktorer som påverkar små företags val att inte anlita en revisor, samt om dessa små företag har något gemensamt.Studien fokuserar på således hur företag uppfattarna fördelarna med revision men vänder på argumenten och ställer frågan varför, trots de uppenbara fördelarna, företag väljer att inte anlita en revisor.Via ett positivistisk vetenskapligt perspektiv, genom en deduktiv undersökning baserad på befintlig teori används av en kvantitativ metod för att samla empirisk data. En undersökning av totalt 400 enkäter skickades ut och av dessa gav 82 fullständiga svar. Hälften av frågeformulären skickades ut till små bolag som inte anlitar en revisor och hälften till de som anlitar en revisor.Enligt resultatet av vår studie kan vi finna statistiska samband bland alla våra tre hypoteser.

Viltanpassad röjning längs skogsbilvägar som en foderskapande åtgärd för älgen

The moose is a keystone species in the boreal forest ecosystem, but the dense Swedish population do cause some serious problems. From a forestry perspective, their browsing on young Scot pine (Pinus sylvestris) causes extensive losses of revenue. Adjusting the cleaning along roadsides of low trafficked forest roads can favour the production of plant species preferred by the moose. This is thought to redirect the moose´s browsing to the roadsides and thereby decrease the damages on commercial forest.The aim of this study has been to present a first evaluation of the vegetation in roadsides, one year after wildlife-adapted roadside clearing has been undertaken. In the wildlifeadapted clearing operation, the roadside was widened by removal of some trees in the forest edge whereupon a complementary clearing with a conventional chain flail was conducted.

Tungmetaller i lakvatten : avskiljning med mineraliska filtermaterial

Four different kinds of filter-materials with reactive surfaces have been studied concerning their capacity to absorb heavy metals in leachate from a municipal waste deposit. The heavy metals studied were: lead, cadmium, copper, mercury, chromium, nickel and zinc. The leachate contains high levels of dissolved organic carbon (DOC) and has a high pH-value along with a high buffer capacity. These characteristics of the leachate make it difficult to remove pollutants and require efficient filters. The filters that were examined in the report are blast-furnace slag with CaO, sand covered with iron oxides, olivine and nepheline.

Orminge i mitt hjärta : en designpedagogisk undersökning om hur boende i Orminge kan ta plats i det offentliga rummet med kollektivt broderi

Denna designpedagogiska undersökning baseras på ett empiriskt material som med en etnografisk inspirerad metod med participatory design som grund för deltagandet, undersöker rätten till individens visuella uttryck i det offentliga rummet, sett ur ett maktperspektiv inom det socialkonstruktionistiska fältet. Syftet är att skapa en mötesplats som kan möjliggöra för boende i Orminge att ta plats med visuella avtryck i ett kollektivt skapande. I Orminge, som är en förort till Stockholm, har undersökningen ägt rum i form av en workshop, en aktion och en utställning. Under tre veckor i oktober 2010 kunde biblioteksbesökare till Orminge Bibliotek delta i en öppen workshop. Deltagarna, de boende i Orminge och tillika besökare till Orminge Bibliotek, "målade med tråd" på duk och bestämde sedan platser där den broderade duken skulle placeras ut i det offentliga rummet.

Giraffens blodtrycksreglering

Through previous studies during my education, I have experienced that chemical deicing road salt is a known problem, mainly in southern Sweden. Road salt causes damage to the environment and also damage to vehicles and structures such as bridges, etc. Road salt causes vehicles and steel constructions to rust, leading to increased costs for repairs of damage to structures. Road salt also causes damage to the plants and the economy to suffer, when plant material and soil needs to be replaced. In order to get closer to a solution, I put up three questions.
