Tillväxthastighet och storleksfördelning hos hassel (Corylus avellana)

To increase the knowledge about the growth of hazel (Corylus avellana)and size distribution of the shoots, circumference and stem diameter wasmeasured in a total of 54 clones in two areas in Östergötland. Further, thewidth of growth rings was determined for separate years. The diameter ofthe stems was measured both out from the centre of the stem andperpendicular to the first measure. The stems showed only a weaktendency to have an oval shape (with the longest side outwards from thecentre). The growth model did not improve when the degree of sunlightof clones was taken into the account.

Gallring med vinkelkran : en jämförande studie av skördarkran med och utan horisontellt ledad vipparm

One of the most important components of a harvester is the crane. Most harvester cranes are only possible to pivot (or horizontally rotate) at the crane pillar. Cranab in Vindeln, Sweden, has developed a new type of harvester crane which has an extra pivot point on the outer boom. This makes it possible to reach around residual trees, easing thinning work in dense stands. The aim of the study was to analyze if the use of a pivoting outer boom (POB) crane gave an increase in thinning production and if there were any differences in time consumption between the work elements for the POB crane and a conventional crane. A Valmet 911.3 equipped with a POB crane was used in the study.

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.

PATIENTENS UPPLEVELSE AV ATT VÄNTA PÅ ETT ORGAN : En litteraturstudie

Bakgrund: Transplantation är sista utvägen vid organsvikt där all annan behandling är otillräcklig. När ett organ slutar fungera väcks svåra känslor hos den drabbade individen, känslor förorsakade av sjukdom och känslor som kötiden skapar då det råder en stor brist på organ och vävnader.Syfte: Syftet med litteraturstudien var att beskriva patienternas upplevelse av att vänta på en organtransplantation.Metod: En litteraturstudie med en kvalitativ ansats har genomförts. Sju vetenskapliga artiklar analyserades med hjälp av kvalitativ innehållsanalys.Resultat: Efter analys framkom tre huvudkategorier som beskriver patientens upplevelse av att vänta på en organtransplantation: Förluster, Storm av känslor och Hantera väntan.Slutsats: Det är viktigt att uppmärksamma patientens speciella livssituation i samband med att vänta på en organtransplantation. För att stödja och lindra patientens lidande i deras upplevelse av att vänta på ett organ krävs en god professionell vårdande relation.     .

Tidsåtgång för rundvirkesmottagning på Södra Cell Mörrum

Mobiltelefonen som social artefakt inom familjen : en studie med föräldrarna i fokus

Studies of modern communication media such as Cell Phones and so called Instant Messengers are popular today. This study focused on these modern techniques, focused on parents as a target group and on what is important for them in everyday communication.By exploratory using three focus groups it became clear that the children, and the link to them was the absolute most important thing for the parents. It became clear that this link to a great extent today exists through the mobile phone.In a following study a Mobile Instant Messenger called My Friends was introduced. It was used by two families during two weeks to see how it would change the communication within the family. The focus was to see how problems with availability were handled, it turned out that:My friends had a more obvious way of indicating availability than the Cell Phone had.

Hållbar energi : - Ett initiativ till utveckling av bränsleceller i Sverige

In the world we live in today the environmental issues has become increasingly important, and we have begun to realize that we can not continue to use fossil fuels at the rate we do. When it comes to generating electricity we are constantly trying to come up with cleaner and more efficient solutions. The fuel celltechnology is one such alternative and has been around for over 100 years. Yet, it is not until now that the world has started to notice this great technology. The fuel cell has been developed in several areas and can today be used for handheld electronics, vehicles and small settlements.

Productivity of integrated harvesting of pulpwood and energy wood in first commercial thinnings

The aim of this study was to quantify the productivity and the costs of different harvesting systems (teams), containing harvesters equipped with accumulating harvester heads and forwarders, in first commercial thinnings were an integrated harvest of pulpwood and energy wood were performed. In the beginning the plan was to study and measure 20 sites before and after harvest. Due to storms during the summer of 2010, complete data could only be obtained from 8 of these 20 sites. Seven of these sites were privately owned and one was owned by UPM, all of the sites had been pre-commercially thinned. The mean stem density before harvest was 2578 stems per ha and the mean stem volume was 0.074 m3solid over bark.On average 1518 stems/ha was harvested.

Samband på individnivå mellan akuta klövskador och cellhalten i mjölk hos mjölkkor :

The purpose of the present study was to investigate the cow-level association between acute hoof lesions and the somatic milk cell count in dairy cattle. Cows from three loose-housed Swedish dairy herds were enrolled in the study if they had an acute hoof lesion treated by a veterinarian or professional hoof trimmer during the preceding year, according to farmer records. Studied lesions were sole ulcer, dermatitis, interdigital necrobacillosis and hoof abscess, in each case causing lameness. For each hoof-diseased cow, 0 to 3 healthy cows were included, matched with respect to herd, breed, parity and lactation stage. Cell counts were obtained from monthly test recordings from one month before to three months after the hoof-lesion diagnosis, and log-transformed.

Influence of prescribed burning and/or mechanical site preparation on stand stem density and growth of Scots pine stands above the Arctic Circle : results 9-19 years after stand establishment

Prescribed burning was commonly used for site preparation in Sweden to establish new forests until the 1960?s, when mechanical scarification was introduced. During recent decades the interest in prescribed burnings has increased again, mainly due to certifications of forestry stating that 5% of the regeneration areas should be burned on dry and mesic soils. The objective of the study was to evaluate actual influence of prescribed burning compared to other site preparation on stand stem density, growth parameters and tree damages for Scots pine (Pinus sylvestris L.) after direct seeding and planting. The study also attempts to simulate growth until first thinning.

Att leva i väntan : En systematisk litteraturstudie om patienters erfarenheter av att vänta på transplantation av vitala organ.

Bakgrund: På grund av bristen på organdonatorer globalt idag tvingas flera patienter i behov av transplantation vänta länge på en operation. Väntan på livsavgörande besked av detta slag har visat sig innebära fysiskt och emotionellt lidande för patienterna och deras anhöriga. Syfte: Att beskriva patienters erfarenheter av att vänta på transplantation av vitala organ.Metod: En systematisk litteraturstudie genomfördes utifrån 12 vetenskapliga originalartiklar, som analyserades med en induktiv kvalitativ ansats.Resultat: Patienternas erfarenheter sammanfattades och beskrevs i fem kategorier: Förändrad självbild, Att leva i väntan, Strategier för att uthärda, Källor till styrka samt Ljuset i slutet av tunneln. Resultatets huvudfynd ansågs vara att ovissheten utgjorde kärnan i väntan på organtransplantation, att anhöriga spelade en avgörande roll för patientens erfarenheter och att en känsla av mening och sammanhang krävdes för att patienterna skulle uthärda och känna hopp under väntan.Slutsats: Patienternas erfarenheter av väntan på organtransplantation visade sig innebära lidande i olika former. Genom att undersöka patienternas känsla av sammanhang, om de uthärdar eller lider emotionellt samt vilka strategier de använder för att underlätta väntan kan sjuksköterskan få tillgång till de redskap som krävs för att lindra detta lidande. Om sjuksköterskan antar ett familjefokuserat omvårdnadsperspektiv kan väntan underlättas för patienterna och deras anhöriga. .

Vederlagsgrundande mätning med skördare

This study was performed in collaboration with Moelven Skog AB, Örebro district. The purpose of the study was to review existing literature in order to describe the current status of harvester based measurement technology as the way to provide information for calculating payment to the forest owners. In addition to this, a short survey was conducted to find out how a switch to harvester based measurement would affect the administrative workload on timber purchasers working for the district. The literature study shows that the harvester measurement technology is ready to use if it is combined with well-established routines for control of the harvesters, methods for automatic quality indexing of the timber and ways of creating pricelists specially adapted for harvester measurement. Pricing each stem seems to be the most promising method. Stem pricing has several benefits.
