Separation av etanol från bakugnsgas
En önskan finns från brödföretaget Polarbröd AB i Älvsbyn att veta om det är tekniskt möjligt och ekonomiskt lönsamt att utvinna etanol ur gasen från bakugnarna. För detta ändamål togs prover på gasen som sedan analyserades med gaskromatografi. Proverna visade att gasen innehöll etanolånga motsvarande en volym av upp till 30 m3 etanol i vätskeform per år. De tekniska och ekonomiska förutsättningarna för att separera ut denna etanol undersöktes och det visade sig vara tekniskt fullt möjligt men ekonomiskt tveksamt att genomföra en sådan separering med konventionella metoder. Nya separationsmetoder under utveckling visade på betydligt bättre ekonomiska förutsättningar.

Verifiering av Kedertakstolen
The Kedertruss is the loadbearing part in the Keder weatherprotectionsystem and it has been analyzed concerning its loadbearing capacity. The Kedertruss is produced and manufactured by Wilhelm Layher GmbH & Co. KG and this report has been made for their Swedish division Layher AB. The Kedertruss, designed in Germany according to German designcode, has been recalculated concerning Swedish conditions according to Eurocodes and a ongoing European standardization project. The two-dimensional program Winstatik Frame Analysis has been used for evaluation of load effects. Capacity has been calculated by hand-calculations and it has been verified that the Kedertruss in its larger spans isn?t able to withstand the loads.
Tillförsel av använda fosforfilter påverkar inte tillväxten eller fosforupptaget hos korn
The eutrophication of inshore seas, lakes and watercourses is mainly due to leaching of nitrogen and phosphorus (P) from agriculture. Many efforts are made to reduce the lea-kage of phosphorus in Sweden and the Baltic Sea countries. Phosphorus is also a finite resource and the mining of good quality raw material gets more and more difficult. Se-dimentation dams in combination with filters is one relatively new method to separate P from run-off and drainage water from agricultural land. This study was a part of an IVL Swedish Environmental Research Institute?s project which tests the capacity and func-tion for separation of phosphorus in four phosphorus filters.
Detektering av mänsklig närvaro i inomhusmiljö
One problem in today?s indoor air quality lies within insufficient ventilation. Dynamic ventilation can be obtained by implementing a Demand-Controlled ventilation (DCV) system. DCV systems adjust the ventilation in a building by calculating the impact made by its? occupants.
Att lyssna till pappors röster : En kvalitativ studie av pappors upplevelser kring att befinna sig i vårdnadstvist
This study highlights the problematic situation fathers encounter when they require help and support in a custodial dispute. Previous research shows the emergence of a new, more involved father. In the light of this earlier research, this study will show a father that is willing to fight for his rights to be a present and engaged parent in the case of a separation from the mother. The aim was to analyze the subjective perceptions of five fathers in custodial dispute. This analysis did not only show how they perceive their role as a father and their masculinity but also the way they feel about the help they got from social services and other institutions.
Barns rädslor och oro i möten med sjukvård : En litteraturöversikt
Barns rädslor och oro i möten med sjukvård Författare: Christian Römberg & Pontus Älvehag Sammanfattning Bakgrund: Enligt barnkonventionen räknas varje människa tills dagen de fyllt 18 år som barn. Omkring 200 000 barn söker varje år vård på akutmottagningar i Sverige och cirka 95 000 barn per år är i behov av vård på sjukhus. I mötet sjukvården upplever de flesta barn rädsla och oro för sjukvårdsmiljön, sjuksköterskans mediciniska språk och beteende vilket kan förstärka smärtupplevelsen vid undersökning och behandling. En uppkommen sjukvårdsrädsla kan försvåra framtida sjukvårdskontakter och skapa otrygghet hos barn. Sjuksköterskans uppgift är att ge barnet en god omvårdnad och möjliggöra delaktighet för barnet och närstående för att dämpa rädsla och oro, något som regleras genom barnkonventionen och hälso- och sjukvårdslagen. Syfte: Att belysa vad som ger upphov till rädslor och oro hos barn i möten med sjukvården som patient. Metod: En litteraturöversikt med kvalitativ ansats.
På bron mitt emellan : En kvalitativ studie av elevers sociala kategorisering utifrån känslorna av inkludering och exkludering i specialpedagogiska lösningar
The purpose of this paper is to find more understanding for pupils in compensatory educational situations and get an idea about how they place themselves in the social hierarchy. In my study I have interviewed four pupils with different experiences from school with the common denominator of being placed in a special class during some hours of the week. The purpose of this placement is to get them to achieve better results in various subjects depending on their grade but this also means a social separation from friends in the ordinary class and this doesn't correspond well with the democratic idea of "one school for all".What I found was that these pupils categorize themselves different from each other and while two of the pupils find themselves very included in the school's social network the remaining two had problems functioning satisfactory in a social matter according to their own liking. The feeling of exclusion though can not be connected to their participation in the special class but rather to their earlier social experiences..

När livsformer möts i mikroföretag
Syftet med uppsatsen är att undersöka jobbcoachningsprocessen utifrån ett livsformsperspektiv, genom att utföra livsformsanalys på jobbcoacher och klienter. Relationen jobbcoach/klient står i fokus eftersom det existerar en liten mängd forskning inom området, och jobbcoachningens effekt på arbetslösheten i Sverige har på senare tid ifrågasatts. Livsformsanalysen är även bra verktyg för att undersöka vilka värderingar människor har och varför vi väljer att agera på ett visst sätt. Teorin om livsformsanalys utgår ifrån att människor har olika levnadsmönster och uppfattningar om "det goda livet", vilket benämns som att de lever livsformer. Vi har lagt fokus på kärnbegreppen sociocentrism och neokulturation inom livsformsanalysen: Sociocentrism handlar om människans oförmåga att förstå och erkänna andra livsformer än sin egen.
Individanpassad omvårdnad : ett steg mot optimal stationärvård för hund och katt
When nursing human patients during hospitalization, the nurse is the one responsible. The nursing is controlled by different models of nursing and careplans, shaped by every patient?s individual needs. This is to guarantee the quality of the care. The veterinary nurse is not ultimately responsible for patient care.
Ekonomi i odling av ekologiskt potatisutsäde :
According to the EEG-councils regulation nr 2092/91, all seed used in organic production
must have organic origin. All seed which is offered for sale must be controlled by
KRAV, and also comply with the rules of the seedlegislation. The seedlegislation
contains demands respecting origin, quality, growingconditions and freedom from
deseases. In this piece of work I will investigate the profitability of organic
potatoseedproduction, and also what it takes to produce potatoseed.
The workmethod has been to, with help from counsellors and growers, make some
compareable calculations for foodpotatoes and seedpotatoes, and also with help from a
literaturestudy investigate which requires an organic seedcultivation must fulfil.
In this piece of work I found out that the organic potatoseedproduction still is to insecure
to be profitable. The attack of potatoleafmould, which is out of control, cause unequal
yields and this will bring that the new EU-rules, concerning organic seed, not seems
defendable yet..
Effektmätning i pump
The interest for power and energy measurement has greatly raised with todays increasing electricity prices and enviromental awareness. In the search for energy efficient solutions, the measurements are more complex due to increasing of non linear components. Harmonics and non sinusoidal voltages put high demands on sampling and filtering. Meanwhile, the price must be controlled so the customer still will find it interesting to invest in smaller plants. ITT W&WW asks for a robust, heat resistant power meter with compact dimensions to allow mounting inside the casing of a pump.

Fertilitet och mortalitet i 1700- och 1800-talets Skellefteå : En modelleringsstudie
This study has the purpose of looking at the current and future position of record labels from a context involving the technological developments, while the opportunities for the artists are changing. As the actors inside them music industry find themselves in an ever changing climate where traditional supply chains are threatened by new technology, the record labels need to change the way they work in order to maintain their existence in the music industry. The study has been conducted by interviewing a number of people involved in the music industry, by using a qualitative method approach. The conclusion of the study shows that the traditional way of doing business by treating music as a product that makes revenue is gone. Instead the labels have to take on new roles formerly run by third parties in order to survive and be profitable, especially since artists can now in control of activities that used to be controlled by the record label..
