Fukthaltsma?tning av biobra?nsle vid Djupeds kraftva?rmeverk i Hudiksvall : Utredning av biobränslen vid Djupeds kraftvärmeverk i Hudiksvall

Tjugoa?tta leveranser av biobra?nsle, besta?ende av grot, bark och sta?dbark har fukthaltbesta?mts med en noggrannare metod a?n den metod som idag anva?nds vid Djuped kraftva?rmeverk i Hudiksvall, detta fo?r att kartla?gga hur exakta fukthaltsma?tningarna idag a?r.Som de flesta andra Kraftva?rmeverk i Sverige anva?nder Djuped vikt och fukthalt fo?r bera?kningar av energiinneha?ll i bra?nslen, denna a?r sedan underlag fo?r betalningar till leveranto?rer av biobra?nsle. Den testfuktma?tning som anva?ndes fo?r att besta?mma en noggrannare fukthalt vid Djuped bestod av sex ga?nger sto?rre prov a?n de som idag anva?nds, dessa visade tydligt att individuella leveranser av biobra?nsle kan variera i fukthalt med upp till 6,8 % och att systematiska samt slumpma?ssiga fel kan fo?rekomma.En lo?sning pa? dessa problem a?r att informera de bero?rda parterna om hur viktiga noggranna fukthaltma?tningar ma?ste vara samt att info?ra en ny typ av manuell provtagning, som fo?rhoppningsvis eliminerar na?gra av de slumpma?ssiga felen. Den nya metoden besta?r av sju till a?tta ga?nger sto?rre prover ja?mfo?rt med den idag rutinma?ssiga fuktprovtagningen och bo?r o?ka noggrannheten vid fuktma?tning avseva?rt.

Vetenskapsjournalistik i radio - Vad får vi veta? : En innehållsanalys av vetenskapsradions nyhetssändningar hösten 2004

AbstractPurpose/Aim: The aim of this essay is to paint a picture of science news reporting in the Swedish Public Service science programme, vetenskaps-radion. Key issues to be adressed are: What areas in science are prioritised? How much of the total broadcast time are devoted to each area? Are there any differences in reporting between weeks? How well does the swedish science radio match common interets? Are the news in the form of short ?soundbites? or are they more lengthy in-depth?Material/Method: Quantitative analysis of radio programmes. The variables used are based on the different major areas in natural sciences.Main results: This study shows that most broadcast time is devoted to news regarding biology and medicine and that the news rather are in the form of short snippets of news than more lengty in-depth stories. This is put in light of how journalistes tend to present news and that the subjects involved has to relate to peoples everyday lives.

Volume and taper equations for Sitka spruce (Picea sitchensis (Bong.) Carr.), Norway spruce (Picea abies (L.) Karst.) and White spruce (Picea glauca (Moench) Voss) in Iceland

The aim of this study was to evaluate different types of volume and taper equations that can be used to predict single-tree stem volume and stem diameter at any given height along the tree stem for plantation grown Sitka spruce (Picea sitchensis (Bong.) Carr.), Norway spruce (Picea abies (L.) Karst) and White spruce (Picea glauca (Mounch) Voss) in Iceland. A number of published tree volume equations were tested and modified to predict the total stem volumes over bark but three logarithmic equations were taken for more in-depth analysis. Three taper equations were tested. Two variable-exponent equations (Kozak 1997, Kozak 2004) and one exponential equation described by Biging (1984). Data from a total of 617 sample trees were used in this study, collected from stands in various parts of the country and present different types of stands growing in different soil types and cover most of the site conditions suitable for forestry in Iceland.

Nerver i karpala flexorretinaklet på häst

The anatomy and physiology of reptiles and mammals are in many ways different, and will therefore possibly complicate anesthetic administration. Lizards are ectothermic and one should keep in mind that a decrease in the lizard?s environmental temperature may result in reductions in anesthetic metabolism. Respiratory depression is a profound problem because lizards lack a diaphragm, making inhalation and expiration completely active processes. This, in combination with cardiac shunting and breath holding makes the effects of anesthesia unpredictable.

Bentiska evertebraters förekomst i källor på Öland

Abstract The benthic macroinvertebrate fauna of 22 natural springs on Öland was sampled, by using a time-standarized kick/sweep sampling technique, in the end of September and early October. The aim was to determine the number of species and their abundances in the macroinvertebrate communities in springs and how/why these may change between different springs. Likewise there was a purpose to investigate possible differences between springs considering the proportions of the number of species and the abundances of the five functional feeding groups; shredders, collectors, filter-feeders, scrapers and predators. There was also an aim to investigate if the distances betweeen springs had any influence on similarity between the communities of benthic macroinvertebrates of the springs. Analysis from the springs collected material showed several interesting patterns in the number of species and their abundances when compared between springs devided into groups depending on their environmental factors such as depth and pH.

Generationsskiften i ägarledda företag : nyckeln till en framgångsrik succession

Background: The development of the Swedish demography is one of the most important social and economic changes ever in Swedish history. Society as well as business is facing an age chock since almost every other company owner is over 50 years old. The complexity of managing a successful succession is pointed out as a major threat to the Swedish economy by the organization Svenskt Näringsliv.Purpose: The purpose with this master thesis is to identify and analyze critical success factors for a successful succession from a going concern perspective.Research method: By using the strong aspects from the quantitative as well as the qualitative method, high level of order and systematic could be reached, without loosing too much details and depth in this particular research. The empirical data was gathered by a digital survey sent to 3000 companies. The quantitative research was complemented by 6 qualitative interviews to increase depth and reliability.Results: The study shows that there is a great incongruence between the expected problems associated to the succession and the actual outcome.

Sambandet mellan parodontit och KOL

Chronic obstructive pulmonary disease (COPD) is a chronic lung disease. The disease is the fourth leading cause of death and more than 5 percent of the adult population worldwide is affected.The aim of this study was to investigate the association between periodontitis and COPD.Search for material for the literature review was done in the medical database PubMed where the keywords were: "Chronic obstructive pulmonary disease" and "Periodontal health or periodontal disease". The result is based on twelve studies that were extracted and analyzed. The studies have investigated pocket depth, attachment loss, plaque index, bleeding on probing and bone loss. Ten studies compared a COPD group with a healthy control group, one study compared two COPD groups and one study examined a COPD group and a group with other lung diseases.Most studies found that people with COPD had a higher incidence of pocket depth, attachment loss, plaque index, bleeding on probing and bone loss.

Utveckling av intranät : med fokus på användbarhet

Intranät används inom många företag idag och det är ett system som används som kommunikationskanal och arbetsverktyg. Ute i organisationer ligger fokus nu på att utveckla de befintliga intranäten, det finns ett behov av att skapa ordning i den växande mängden data/information/applikationer (Bark et al., 2002).Tyvärr finns det många problem och svårigheter med utveckling och införande av IT-stöd, så som intranät, i organisationer och resultatet blir IT-stöd med stora tekniska brister som är svåra att använda. En orsak till detta är att användarna av systemen inte står i fokus, det är svårt att få användarnas krav och behov att styra utvecklingsarbetet (Gulliksen & Göransson, 2002). För att lyckas med en intranätssatsning är därför en analys av de anställdas behov ett måste (Bark et al., 2002).Syftet med denna uppsats är att, vid utveckling av ett intranät på ett fallföretag, undersöka användarbehoven i syfte att öka användbarheten. Detta görs genom att ta reda på brister och förtjänster med ett befintligt intranät och utifrån detta skapa ett informationsunderlag för att vidareutveckla ett intranät.

Rhododendron ur undersläktet Vireya - något om dess karakteristika och användning i nordiska vinterträdgårdar :

Present essay aims to introduce the reader to central topics regarding Rhododendrons of subgenus Vireya. As a result of a donation, the Swedish University of Agricultural Sciences, received a collection of Vireya from a local amateur grower, Kurt Myllenberg. Since the subgenus Vireya is uncommon in Scandinavian horticulture, the study tries to establish conditions for successful growing. The subgenus Vireya differ from the other Rhododendron species through mainly three characteristics: the presence of two tails, attached to each end of the seed; the ovary-style junction is tapering and the pedicels arises directly from a dome-like base and form an umbel and not a raceme. The subgenus is distributed mostly in the islands of Indonesia and New Guinea, but also from Malaysia to Nepal and in Australia. Since Vireya species mainly grows as epiphytes in the tree canopies, they need high drainage and not too much water.

Ett tillgängligt och användarvänligt boende : Anpassningsmöjligheter för människor med rörelsehinder och nedsatt rörelseförmåga

In this paper we have theoretically built a house designed for people with impaired mobility. Theessay begins with an introduction in which the purpose of the work, the methodology and thedepth-research part is presented. Then the layout that explains how we intend to adapt the housefor the demands detailed in the depth-research part is presented. In the same chapter variousstructural components, such as different floors and walls, are specified.In the selection of materials we have taken into account the criteria of our specialization andadaptation to the aesthetic aspects, where we evaluate materials based upon our wishes regardingtechnique and form. There are also other aspects that are important in the selection of materials,including that these are adapted to technical traits of the construction elements and installations.In a later chapter the technical installations such as ventilation systems, heating systems,electricity and sanitation are presented, where both technical and financial aspects are describedin detail.

Fissurförsegling på studentklinik : Kartläggning av retention och kariesförekomst

Syftet med denna studie var att kartlägga retentionen av resinbaserade fissurförseglingar på sexårsmolarer utförda på studentklinik. Karies registrerades även på övriga sexårsmolarer. Materialet utgjordes av 51 barn födda år 1999 eller 2000 med minst en fissurförsegling på sexårsmolaren utförd av tandläkarstudent. Fissurförseglingen skulle vara utförd i Delton® och ha en minsta uppföljningstid på ett år. Data registrerades från journaler avseende allmänhälsa, medicinering, kariesdata och riskgrupp.

Morgondagens reklambyrå : en studie om hur reklambyråer har påverkats av dagens förändrade mediebild

The purpose with this final paper was to examine how the collaboration between parents and teachers can manifest itself. With collaboration, we mean the dialogue that has to exist between parents and teachers in regards to e.g. how well informed the parents are about the regulated principles on which the education plan is built on, and in which way they can take part in and influence the system. This is to empathize on the fact that a good collaboration between parents and teachers help create a good foundation for the pupil?s ability to learn.The method that we have used are questionnaires given to parents and teachers along with studies of literature both as means of furthering our studies as well as a basis for the design of the questionnaires.

Hur skapar man ett leende? : En uppsats om personalmotivation

Our purpose with this paper has been to analyse and discuss how motivation of the personnel affects the service quality in service companies. This has been done through two studies; a literature study with existing theories and an empirical study on the divisions of Lyckohjul and Shopping at Liseberg. In the introduction of this paper we put the question of research; why is there a need for work of motivation in service companies. When collecting information we used literature briefing, a questionnaire study and depth interviews. The literature briefing focused on the well-tried and most dominating theories on the subject motivation.
