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.

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.

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.

Mönsterminnen - att skapa nya mönster av gamla minnen

This is a project about creating new patterns from childhood memories of patterns. I havebeen reaserching the possibility to add further value to a pattern in terms of memories, stories,associations and feelings.The goal has been to create new patterns from other peoples memories of patterns. It hasalso been my purpose to develop my skills and feel more comfortable in the creating of patterns.The questions at issu has been:How can I tell a story with a pattern?How can I communicate a feeling or a mood with a pattern?How does our memory image and an interpretation effect the process and the end result?I interviewed nine people. The questions during the interview was:Your name and age?Where was the pattern you?r going to talk about placed?How did it look like?What kind of feelings or emotions do you connect with this pattern?Someting else you whant to tell about the pattern?I created five patterns and during the process with the interviews I realised the importance ofshowing the stories in the end result.
