The aim of the study was to compare productivity in first thinning of birch stands, when either energy- or pulpwood was harvested. The systems total profitability was also compared by including forwarding and chipping costs. A Gremo 950 HPVR harvester was used and the same driver was used under the entire study. During the pulpwood harvest a Logmax 4000b harvester head was used and a feller buncher head made by Silvatec was used during the energy wood harvest. Six study unit pairs were located in a birch dominated stand outside Ängelholm in Skåne.

AbstractIn this study you are going to meet the Nordic Good Thor. I will present a short historic presentation of the Nordic mythology, about the Ragnarok and also I will give a short presentation on several other Gods. I have done three film analyses on movies about Thor. The movies are Thor, The Avengers and Thor- the Dark World. I have compared these three movies about Thor with the Thor that is presented in the literature. I have seen closely on the appearance of Thor, his character and his family situations.

Many companies choose to market their products and brands with help from celebrities. This is not a new phenomenon, though, this strategy is something that we consumers start to get used to and the risk that the consumer unconsciously unselects the message grows. A recently much-disputed theory is the use of incongruent marketing. This means that companies uses a marketing message with the objective to not match the consumer?s expectations.

Hemoglobin is an oxygen binding protein in erythrocytes. Hemoglobin is composed of four polypeptide chains. During the fetal stage the type of hemoglobin called fetal hemoglobin (HbF) dominates. After birth HbF is replaced by adult hemoglobin (HbA). HbF persists in concentrations less than 1%.

Livestock animals affect their environment in a number of different ways, mostly through grazing and trampling. This study focused on the effects of Gotland pony grazing on forest structure and diversity, and the impact on ground cover. To compare the fenced and grazed area with a reference area outside the enclosure a number of transects were used. The study showed that there was no significant difference in height structure and diversity between the compared sites; however, there were a significantly higher proportion of damaged trees inside the enclosure. The ground cover variables showed a higher amount of bare soil, plant litter and wood-rush (Luzula sp.) inside the enclosure whilst grass was more frequent in the reference area.

When I began my studies at Gammelkroppa forest school I started to think about an appropriate thesis. There was much discussion about the wild grazing damage during that period. I was at that time a part of Boo property and helped at their great hunts. They had the dual uses of wildlife and forest. I decided that I want to study how big the wild grazing damages are and if we can reduce them.

Platelets are important for the healing of damaged blood vessels since they have an importantpart to play in the coagulation process. At the same time, the blood must be kept fluid and notcoagulate at the wrong time. Therefore there are factors that effect the aggregation of plateletsin a positive or a negative way.Previous investigations have shown that platelets during stirring conditions produce reactiveoxygen species (ROS) that weaken the inhibiting effect of nitric oxides (NO) on platelets andthat the drug Dexamethasone (Dex) can reduce the ROS-production.The aim of this project was to investigate if glucocorticoids, in this case Dexamethasone,could restore the inhibiting effect of NO on platelets and if there was any decrease in ROS-production.The result of the ROS-measurements showed a great variance and it was difficult to draw anyconclusions from them, but a clear decrease in ROS, as previous reported, was not shown. In the aggregation experiments the inhibiting effect of NO was observed through the drug S-nitroso-N-acetylpenicillamine (SNAP), a NO-donator.From the aggregation experiments, the result seemed to be that SNAP during longerincubation time lost its inhibiting effect, probably because the cells become desensitized.With superoxid dismutase (SOD), the effect of SNAP increased, both in the experiment withlonger and shorter incubation times. Dex seemed to reinforce the aggregation in relation toboth SOD and SNAP.

Syftet med denna rapport var att ta fram underlag som ska kunna ligga till grund för en eventuell framtida standardisering av brandvattentillgången på rangerbangårdar klassade som farlig verksamhet. Detta har gjorts genom litteraturstudie på ämnen rörande rangerbangårdar, farligt godsolyckor, brandvattenförsörjning samt lagstiftning som styr anläggningar klassade som farlig verksamhet. Utöver en omfattande litteraturstudie har intervjuer med två räddningstjänster genomförts för att få deras syn på brandvattenförsörjning av rangerbangårdar. I Sverige finns 13 rangerbangårdar som alla ägs av Trafikverket som enligt Lagen om skydd mot olyckor (LSO) är skyldig att i skälig omfattning hålla och bekosta utrustning för släckning av brand. Konsulter har på uppdrag av Trafikverket utfört riskanalyser på några av de rangerbangårdar som är klassade som farlig verksamhet och kommit fram till att brandvattensystemen på flera av rangerbangårdarna måste utredas vidare då de anses vara underdimensionerade och otillräckliga.

Detta examensarbete har utförts hos Liko AB i Alvik, Luleå. De säljer främst personlyftar för rörelsehindrade människor, och deras kunder finns i Sverige och i ett 20-tal länder till. Logistikavdelningen på Liko AB har insett att transporter från dem till deras kunder är en viktig del i deras arbete. I dagsläget anlitar de till största del Schenker AB för transport och de har liten insyn i, och dålig kunskap om, den delen. Syftet med detta arbete är att kartlägga hur transport från Liko AB till kund fungerar i dagsläget.

The first vampire film I ever saw was Interview with a vampire. ?I haven?t been human for two hundred years?, opened up not only the film, but a whole new world I knew nothing about. The world, as it were, opened its doors to me again after I had seen the film adaption of Stephenie Meyers Twilight. I decided to write down a few thoughts, capture my frame of mind, and these paragraphs then turned into a text: ?I tankarnas skal?.              When I did research for this essay I discovered that my text held certain similarities with the modern vampire novel.

At the beginning of the 1970´s forestry feared an imbalance in the future wood supply. Because of this anticipated "timber slump" forest companies undertook a variety of measures to counter this. One of these measures was the introduction of exotic tree species. The choice finally ended up with lodgepole pines which were considered a fast growing tree species compared to our native tree species. Theambition for the new lodgepole pine stands were to run these with rotation periods of between 40-60 years, thus smoothing out the ?timber slump? that was anticipated.

Mechanical harvesting may result in timber damages leading to reduced saw log quality. The initiator of this study was VIDA ? a privately owned concern operating in the value-adding process industry of forest raw materials. The aim of this study was to examine the type and amount of damages on Alvestakubb caused by the harvester head during the cutting process. The aim was also to compare the damages caused by different types of feed rollers and to evaluate the effects of temperature on damage occurrence.

Weland AB är ett familjeföretag som startade 1947 med sitt huvudkontor i Smålandsstenar. Här finns ungefär 250 anställda som jobbar på ca 60 000 kvadratmeter. Ryggraden i Welands verksamhet är tillverkning av pressvetsad gallerdurk som går att se i konstruktioner som trappor, både spiral och raka.Projektet grundar sig i att ljudnivån vid en maskin för kapning av gallerdurk är hög och därför har personalomsättningen också varit hög. Syftet med projektet är att konstruera komplement till en kapmaskin för att göra den helautomatisk. Det skulle göra att en operatör inte behöver vara närvarande mer än för att förse maskinen med material, programmera maskinen och bortföra pallar med färdigt gods.

Unhealthiness is not just a damaged back or asbestos. The fact that mental ill-health seems to increase in our society is well known. Statistics from Arbetsmiljöverket proves a fourfold increase of work-related disorders since 1997. These are primarily caused by organizational and social factors, 60% are considered caused by stress and a heavy workload. Sick leave due work related fatigue and depressions are scarily common today.

Global uppvärmning genom växthuseffekten och nedbrytning av ozonlagret är idag den stora globala miljöfrågan. Till följd av större fokus på miljöfrågor, har allt fler företag ökat omfattningen på sitt miljöarbete. För att få insyn i den egna verksamhetens klimatpåverkan krävs kartläggning och analys av utsläppsgenererande verksamhetsområden. Enheten LFV Data inom LFV, tidigare Luftfartsverket, vill utöka sitt miljöarbete till att även omfatta klimatpåverkan som verksamheten ger upphov till indirekt. Detta examensarbete syftar till att kartlägga och analysera huvudflödet av tjänstedatorer (BAS-IT-produkter) inom LFV ur klimatperspektiv.
