Rökgaskondensering : Ett möjligt alternativ för Nybro Energi AB?
Syftet med undersökningen var att klargöra om en rökgaskondensor är en bra investering för Nybro Energi AB. Saxlund Bioenergy AB kontaktades för sammanställning av offert. Med hjälp av parametrar från Nybro Energi AB och offerten från Saxlund Bioenergy AB, gjordes beräkningar för att avgöra om en investering är lönsam. Resultatet av undersökningen visade att en investering av sådant slag som behandlats i detta arbete var intjänad efter mindre än sju år i drift och effekten som är möjlig att utvinna uppgår till 2,8 MW, förutsatt att panneffekten utgjordes av minst 15 MW. Slutsatserna var att investeringen inte var betald efter sju år med underlag av att kostnader som utgjordes av eventuell ombyggnation inte var behandlade i undersökningen, detta innebar dock inte att en investering ärr olönsam då dessa kostnader uppskattades som små i förhållande till den totala besparingen efter att den ekonomiska livslängden på 15 år har löpt ut..
Faktorer som påverkar Vänerns öppna sandstränder och möjligheterna för hög biologisk mångfald ? med mossor som indikatorer på igenväxning
The sandy beaches of Vänern are threatened by overgrowth and thereby the biodiversity is at high risk to decline. This study is based on an inventory of vegetation of overgrowth character and mosses. The frequency and spread of mosses is perceived as an indication of initial or present overgrowth. External factors that have been taken into consideration are wind-, wave- and ice erosion, the slope of the beach, wear and grade of exposure. The purpose of the investigation is to control the beaches grade of overgrowth and find out which external factor is of most importance for the maintenance of the biotope. The results show that the beaches environment is affected by the slope of the beach, grade of exposure, size, wear and overgrowth.
Biologisk behandling av oljeförorenad jord : Abiotiska faktorers inverkan och effekter av olika uppläggningssätt på nedbrytningshastigheten.
The purpose of this report was to investigate how the abiotic factors (temperature, pH, nutrients, oxygen levels and water content) would affect the decomposition of oil-contaminated soil and how a variance in structured soil would affect the decomposition-rate. A minor field-study was made and soil where structured in five different ways (one was a default pile and was used as a reference). The study took place over 137 days and three samples were taken (start, middle, end) and analyzed for aromatic and aliphatic compounds. The result of this study shows that there is a significant difference between all methods for the aliphatic compounds and no significant difference for the aromatic compounds. The abiotic factors that affect decomposition vary from organism to organism, depending on what type of environment it will function the best.
Undersöka förbättringspotential med verktyg från Lean produktion
In the year 1783 a fissure eruption from Laki in the southern part of Iceland produced a large amount of volcanic gases during a period of eight months. The volcanic gases and aerosols spread across the northern hem sphere due to ideal weather conditions and had a substantial impact on the environment, human health and also climate effects. This, so called dry fog, caused severe health problems, which led to death casualties, killing animals, crops and other vegetation. The consequence was a widespread famine which was aggravated by a hard and long winter in 1783/84. Analysis shows that the Icelandic volcanoes are the primary risk to produce dry fog that can affect Sweden.
Om stenar kunde tala : arkeologiska rön och bebyggelsehistorisk kontext av kvarnstensbrottet Östra Utsjö i Malung
This paper deals with village history around millstone quarry Eastern Utsjö in Malung, Sweden, in the hope of finding deposits that could date the quarry, in that the quarry in the current situation is dated only by the millstone fragments outside the resort. My purpose was to conduct a discussion on the quarry alone can be dated by deposits outside the resort. I have used FMIS RAÄ:s fornsök and a lot of literature to identify village history. The results showed that it is not possible to date the millstone quarry from village history, but through deposits outside the resort of Malung, which have been found around Mälardalen, Sweden through archaeological excavations, and derived from the millstone quarry Eastern Utsjö, can put an age on the quarry..
Varmhållen och kyld skolmat : En jämförelse med fokus på energianvändning mot bakgrund av livsmedelssäkerhet och näringsretention
The aim of this report has been to investigate the use of electricity energy before and after a conversion of foodservice. The ambition was also to highlight the food safety and the retention of nutrients in relation to the conversion. The methods being used were qualitative interviews, case studies, study visits and literature. The equipment and the use of energy was the same in 2008 as in 2011 for hot-holding of the tested component, sauce with ham. The chilled system used more than three times the energy and cost for one portion than one portion in the hot-hold system.
Transparens i svensk valkampanjfinansiering
Despite the fact that the issue has been discussed for several decades, there are still no rules in Sweden mandating political parties and candidates to disclose received donations. Because of this lack of transparency, Sweden is not fulfilling some of its international obligations and has fallen behind in the international trend to increase the transparency of election campaign finance. The lack of disclosure rules in Sweden has led to extensive criticism, most notably from the Council of Europe´s group of states against corruption, Greco, who criticized Sweden in light of the guidelines on the subject from the Council of Europe. At this writing, a new proposal for disclosure rules is being prepared at the Department of Justice, DoJ. The proposal is to be presented in spring 2013.
Nautisk turism : en jämförelse mellan svenska och kroatiska förhållanden
AbstractA tourism genre that has developed in recent years is the nautical tourism, nautical tourism is described as a tourism genre that includes all activities in relation to water. Croatia is one country that has invested in and has good presumption for this type of tourism, and has also received an international recognition as a top destination within the nautical tourism genre. The purpose with this thesis is to increase knowledge about the nautical tourism development in Croatia, and to see if it would be possible to develop on Swedish conditions. Sweden is a destination with a large number of archipelagos, located in both inland lakes and along coastal areas. Stockholm archipelago is one of the world's largest archipelagos which has a long tradition as a tourist destination.
Betydelsen av kön och sexualitet i mötet med sjukvårdsrådgivningen.
SammanfattningDetta är en studie av sjuksköterskors bemötande av patienter på Sjukvårdsrådgivningen i Region Skåne. Syftet är att undersöka hur det helhetstänkande som är vanligt förekommande i teoretiska debatter om sjukvården är förankrat i den praktiska verksamheten. Jag fokuserar på bemötande som kompetens, och studerar dess plats och auktoritet i organisationen. Jag undersöker även hur helhetstänkandet praktiskt fungerar i mötet mellan sjuksköterska och patient genom att fokusera på hur kön och sexualitet synliggörs och beaktas i samtalen.Jag utgår från Judith Butlers teori om den heterosexuella matrisen och om hur kön och sexualitet görs genom social interaktion. Jag använder mig också av intersektionalitet som ett analysverktyg.
Sothönans ( Fulica atra ) miljökrav vid häckning i utbredningsområdets randzon
In Sweden you will find the coot chiefly in the southern parts. The species winters in the southern part of the Baltic Sea and along the coasts of northern Europe. The number of coots is heavily decreased by harsh winters. The population of the coots in Sweden is estimated to 20 000 to 30 000 pairs. The region of Dalarna is the random zone for the breeding of coots in Sweden .

Jag vill inte ha n?gon gruva, men jag hoppas att det blir en. En kvantitativ inneh?llsanalys av gestaltningen av uranbrytning i ?stersunds-Posten
Aim of thesisThe aim of the thesis is to understand how the issue of uranium mining is framed in ?stersundsPosten, the biggest local newspaper in the county of J?mtland, where one of Sweden?s largesturanium deposits has been found. This is done by examining how uranium mining itself isframed, who gets to speak about it, and how the framing has changed over time.TheoryWe use framing to analyse how the placement of words, pictures and actors in specific parts ofthe texts can contribute to how uranium mining is presented in ?stersunds-Posten.MethodQuantitative content analysis is used to examine a total of 193 articles from the years 2005,2010, 2018 and 2025. The content analysis is focused on the presence of evaluative words,arguments and actors in certain parts of the texts, most importantly the headlines, photographsand quotes.ResultsThe results show that uranium mining is framed by negativeness, especially surrounding thepossible effects on the water in J?mtland.
Reservvattenförsörjning i Stockholms län : en hållbarhetsanalys
Befolkningen i Stockholms län väntas öka med omkring 445 000 personer från år 2010 till år 2030. Det ställer krav på många samhällsfunktioner, däribland dricksvattenförsörjningen. Idag försörjs mer än 90 % av länets invånare med vatten från Mälaren. Vattenförsörjningen kommer behöva anpassas efter befolkningsutvecklingen, både för att producera tillräckliga dricksvattenvolymer och för en driftsäker leverans. Vid problem med den reguljära dricksvattenförsörjningen kan vattenleveranserna säkerställas genom tillgång till reservvatten-täkter.
