En j?mf?rande studie mellan tv? v?treng?ringsmetoder p? papper
Amongst the published literature researching wet cleaning of paper there is a limited amount of
studies conducted researching the method simmering water treatment. There are even less studies
conducted on how simmering water affects the paper being treated when used as a cleaning method.
Despite the limited research, there are literary reviews describing the method and suggesting it as an
alternative for conservation of paper with iron-gall ink. The following study will therefore be
examining, the somewhat unusual method, simmering water treatment, and comparing it to one of
the more common wet cleaning methods: immersion washing. This is done to compare how the
different temperatures of the water affect the paper.
The types of paper used in this study consists of three dyed and four undyed papers. All of the papers
are new, apart from one sample originating from 1847.
Återfjädring vid bockning av höghållfast stål
Svenska Aerogel AB has developed the material Quartzene® which is of the typeprecipitated silica and contains calcium - magnesium silicate ((Ca, Mg) SiO3). Thematerial is used for molecular filtration of contaminated air. Qartzene?, which is inpellet form, is porous and has a high internal surface which is a requirement for themolecular filtration. With the use of various impregnations, filtration can affect thedesired outcome.
Är delad järngiva till smågrisar lönsamt?
Ledinflammation är ett vanligt problem inom smågrisproduktionen, där cirka 10 % av alla födda smågrisar drabbas av ledinflammation under sin livstid. Ledinflammation orsakar både smärta hos grisen och ekonomiska förluster för lantbrukaren, genom nedsatt tillväxt och ökad arbetstid för behandlingar samt kostnader för medicin. En tidig och stor järninjektion har ansetts vara en bidragande orsak till ledinflammation bland
vissa forskare. Överflödet av järn ger en gynnsam uppförökningsmiljö för bakterier.
Järnet har flera funktioner i kroppen, bland annat i uppbyggnaden av blodet. Blodets röda färg kommer från hemoglobin som har till uppgift att transportera syre och
koldioxid mellan lungorna och övriga vävnader.

Riskbedömning av miljö- och hälsoeffekter efter järnhanteringen i Strömsbergs bruk
Risk assessment of effects on the environment and health outcome caused by the iron industryLina LöfqvistIn Sweden you can find lots of contaminated areas, which can create problems for both humans and nature. To reduce the long-term contamination grades, Naturvårdsverket have created a report with regard to the contaminated sites. This builds on the ?Method for Inventories of Contaminated Sites? which is abbreviated MIFO. The aim of MIFO is to achieve better environmental planning in Sweden.
Att ta vara på solens fulla uppvärmningskapacitet
The purpose of this bachelor´s report is to expand the knowledge about heat supply of a small house in Malmö. The heat supply will be provided from solar panels in combination to two accumulator tanks which will storage the up heated water and a pellet boiler.The technique used here is warmth storage in water over seasons, which will provide the total need of heating for the house. Accumulator tanks in combination to solar panels gets more and more common in Sweden but this far it´s unusual to use it for storage over seasons. This report will highlight many of the difficulties associated whit heat storage and give information about a system's possible design and function.The design of this system is decided early on. An accumulator tank is placed 2 meters down in the earth on the backside of the house.

Vårdprogram för Österby bruks köksträdgård :
Svenska (engelska se nedan)
Detta examensarbete är ett vårdprogram över Österby bruks köksträdgård. Österby bruk är beläget i norra Uppland cirka fem mil norr om Uppsala. Redan på 1500-talet började järnindustri växa fram på Österby. Österbys järnindustri kom att pågå fram till nedläggningen av Österbyverkan 1983. Dagens köksträdgård tillkom i och med den omgestaltning av hela herrgårdsanläggningen som startade på mitten av 1700-talet.
Duende : En analytisk studie av Federico Garcia Lorcas estetiska begrepp och dess inverkan på Bruno K. Öijers Trilogin
This paper examines how the Swedish nationalistic political party Sverigedemokraterna communicates regarding the crisis they experienced when the Swedish newspaper Expressen published a few video clips of three, in that time, highly important party members that got in an argument after a late night of drinking. Two of the party members were at the time of the publication the members of the Swedish parliament and all of them had important senior positions in the party. In the argument one of the party members used abusive, offensive, sexist and racist language while all acted threatening and even armed themselves with iron bars from a nearby construction site.The aim of this paper is to examine how the party Sverigedemokraterna conducts their crisis communication, if they apologies and the fashion of the apology. A press conference with the party leader and the most active user of abusive language and also an interview with the second member of parliament who is involved in the argument are studied. The rhetorical arena is used to describe and pinpoint the most important stakeholders in the crisis.
Gravar i stenskepp : Osteologisk analys av brända och obrända ben från skeppssättningar på Gotland
In this study bone material from six stone ship settings and a total of seven deposits of bones from two sites on the island of Gotland have been analyzed. Four ship settings from the burial site at Gålrum in Alskog parish and two from Tängelgårda in Lärbro parish. The ships contained both cremated remains and inhumations. Human remains were identified in five of the analyzed ship settings and a minimum of six individuals was identified in total. Animals were found in three of the ship settings, where one of them contained only the burned remains of a dog. Two of the ships contained inhumations, one in Gålrum and one in Tängelgårda.
Språket vår Järnbörd : Språket spelar roll
In this paper I make an analysis of the play Järnbörd (By burning Iron) written by the swedish author Magnus Dahlström. In this play all the characters has committed horrible crimes wich they easily describes the violence. The starting-point of my analysis is the text itself and not any stage-setting. The reason for this is that I find it interesting to see what can be found in the text only. I investigate if the language itself can tell something.Furthermore I discuss Magnus Dahlström´s literary language and if he has any distinguishing quality, and if so what it may be.
Robotiserad produktionsanpassad magnetmontering för vågkraftverk
This thesis work includes studies and simulation how magnetization of the translator in a linear generator for wave power can be automated. The translator is the moving component in the generator that is "dressed" with permanent magnets. The translator is magnetized with rectangle-shaped permanent magnets that are today's strongest permanent magnet type of neodymium-iron-boron (NdFeB).Eight equivalent metal sheets are mounted around the translator. The plates have milled tracks where 106 permanent magnets per sheet are mounted. Today the assembling of the magnets is done by hand, which is a very tedious and time-consuming work. This project presents investigations about the automation of the translator magnetization theoretically and simulation results are preformed in ABB's robot simulation software RobotStudio. Even robot-held tool was designed that enables the robot to be able to magnetize the translator in a simple manner. The investment cost is roughly 1.5 million SEK. With an economic life-time of five years, the investment costs are estimated to 24000 SEK / month. According to the calculations, this project is very motivated to implement, as it provides savings up to 17 000 SEK per translator which is 10.2 million SEK assuming that the robot cell is operating at full speed the whole year.According to this thesis work the result is a 4x9 meter cell with two industrial robots of the type ABB IRB6650S.The cycle time to magnetize one translator was calculated to about 10 hours.This prototype of project can possibly be implemented in a full-scale production line and performed according to the calculations and simulations presented in the report. Further work is suggested to improve the tool.Lyssna .
Civila musikkårer i landskapet Värmlands bruksorter : Betydelsen av faktorerna ekonomi, rekrytering, musik och kulturskolan, samt samverkan med studieförbunden för musikkårernas överlevnad
This bachelor thesis is about civilian marching bands in the province Värmland industrial communities, with a focus on Degerfors, Edsvalla, Gruvön, Nors, Slottsbron, and Vålberg bands. Degerfors, Gruvön, and Slottsbron bands are three corps that still operates concerts and performances. The other three unions are defunct.In Värmland, there were many mills that were operating well into the 1900s, roughly speaking there were about 25 mills in various industrial areas. These mills had operations in glass, iron, and paper, each user had a band at least a brass sextet and today there are only eight bands left in Värmland. Bofors in Karlskoga, Charlottenberg, Degerfors, Dejefors, Gruvöns in Grums, Hagfors, Skoghall, and Slottsbron bands.What is the reason that so many bands have disappeared? To answer the question I have investigated the importance of four factors have had for the unions: finance, recruitment collaboration with the music and arts, as well as cooperation with educational associations.The results show a marked reduction in civil bands, from about 25 corps to eight corps today.

Driftoptimering av Luleås fjärrvärmesystem
Produktionen och distributionen av fjärrvärme i Luleå kommun sköts av två företag, LuleKraft AB och Luleå Energi AB. Under 2011 utökades samarbetet företagen emellan, med bland annat gemensam driftspersonal. Detta ger förutsättning för ett mer anpassat och optimerat produktionssätt. Med detta som bakgrund skapades en modell över fjärrvärmenätet och tillhörande anläggningar, för att kunna skapa riktilinjer för effektiv produktion vid olika driftförhållanden. Viktiga komponenter för systemet är? Lulekraft - ett kraftvärmeverk vilket eldar processgaser från SSAB och olja för att producera fjärrvärme och el? Fjärrvärmenätet - 42 mil långa ledningar förser i princip hela Luleå kommun med fjärrvärme? Hetvattencentraler - när LuleKraft inte räcker till för att täcka fjärrvärmebehovet finns möjligheten att använda dessa där bränslet är processgaser, olja, pellets eller elFjärrvärmenätet och hetvattencentralerna ägs av Luleå Energi AB men hela systemets drift sköts av personal på LuleKraft.
