Förekomst & kostnad av kapsprickor i stormaskadad skog

The aim for this study where to investigate the frequency of cutting cracks in saw timber harvested in the storm-damaged forests in regions where the storms Hilde and Ivar hit. The idea for this work came from one of the region?s biggest actors, SCA Skog and Jämtlands district. The purpose where to find out how big proportion of the saw timber that contains cutting cracks, their financial cost in lost wood value and also give advice and suggestions on how to work against the frequency of cutting cracks. For the field-study some guidelines where used to make sure that the samples were taken under the same conditions, they were: ? The field-study must be performed under harvesting of storm-felled forest, which are horizontal/inclined trunks. ? The averaged sized tree will make it possible to harvest saw timber. ? The trunks can?t be root cut. A methodology called in Swedish ?Trissmetoden? was used because it is the most frequent used methodology in earlier performed studies and the only one that can be used I field. Under the field-study data were collected from 570 saw timber logs, 30 logs from each one of the tested harvesters.

Fortplantning och fortplantningsproblem hos tikar av svensk och finsk lapphund : en jämförande studie

Vaccination against boar taint - effect of restrictive and semi ad libitum feeding regime on production and behavior

Male piglets have been castrated for centuries to avoid contamination of their meat with boar taint, a strongly unpleasant odour that makes the meat inedible. Today boar taint can be prohib-ited by vaccination against gonadotropin releasing hormone (GnRH) using Improvac®. The aim of this study was to evaluate the efficiency of vaccination on growth performance and behaviour of vaccinated male pigs compared to surgically castrated male pigs. The effect of two feeding regimes, restricted (SLU-norm) and semi ad libitum, was also included in the study. At birth, pigs (n=206) were randomly allocated to the two treatment groups; surgically castrated and vaccination.

En kvalitativ studie om hur personer med utländsk bakgrund upplever att integrationen fungerar i Sverige

Abstract Aim: Since there is a lack of research based educational interventions concerning the relationship between coaches and young athletes, the aim of this study was to implement and examine the effects of sport psychology intervention for coaches in a track and field club. The research questions were: What are the effects of an educational intervention for coaches, with focus on a motivational climate, on: A) the coaches´ coaching approach B) their athletes´ goal orientation and C) their athletes´ perceived competitive anxiety?Method: The coach education stretched over two months and consisted of four two-hour lessons with focus on motivational climate, goal orientation and sport anxiety. Six coaches (three females, three males), aged 38-52 (M=44.33 years, SD=4.84) and their 59 athletes (27 males and 32 females) aged 12-14 (M=13.10 years, SD=0.82), participated in the study. A control group of 35 athletes (10 males and 25 females), of the same age (M=13.46 years, SD=0.70) and with similar demographic data, was also recruited.

Utvärdering av radiologiska kriterier för att bedöma tillståndet ileus på hund :

Dogs presenting with vomiting and abdominal pain, are common patients at the small animal clinic, and the reason for these symptoms can have various aetiologies. One common reason for these symptoms is obstruction of the small intestine caused by a foreign body. Obstruction of the small intestine is best diagnosed by using radiography, contrast-study if needed, and ultrasound. To avoid further examinations, diagnosis from plain radiographs is preferable. One of the signs of illness one can detect from these examinations is a dilation of the small intestine proximal of the obstruction, caused by gas or fluid; ileus.

Spelrörelsekrav och temporalt mönster i amerikansk fotboll : en deskriptiv studie av försvarsspelare

AimThe aim of the study was to develop a method for the survey of play movement demands and temporal patterns in order to enable a descriptive study of the defensive players in American Football. The overall aim was to  improve the understanding of how American Football is played to create opportunities for enhancement of current or developing new training methods to better suit football.MethodFifty plays from a Division 3 college football game on video from 2005 was divided into sequences of action for one player each from the defensive line, linebackers and defensive backs and analyzed with the video analyzing software cSwing. Every players sequence of action was recorded in a spreadsheet and noted on a scaled football field where distances were measured and together with time stamps from cSwing velocity was calculated.ResultsUsing this method it was possible to describe the play movement demands and temporal patterns which was the main task of the study. The defensive end worked on an average 4.61 seconds per play, the distance was 12.4 meters and average speed 2.5 m×s-1. The linebacker worked on an average 4.35 s per play, 13.7 m and at a mean speed of 3.0 m×s-1.

Risk i fastighetsbolag : - en kvantitativ studie av kommunala och privata fastighetsbolag

Jämfört med andra branscher har fastighetsmarknaden låg avkastning på totala tillgångar, de utnyttjar istället en hävstångsstrategi för att skapa mer effektiv utväxling på eget kapital. Det finns många riskvariabler kopplat till fastighetsbranschen och flera sätt att differentiera sig från den osystematiska risken. De kommunala fastighetsbolagen har en finansieringskälla Kommuninvest, som enbart vänder sig till allmännyttiga bolag och inte privata aktörer.Syftet med uppsatsen är att historiskt analysera hur risk och avkastning genererats av kommunala och privata fastighetsbolag. Metoden är kvantitativ, kombinerat med en deduktiv metod och som har en förklarande ansats.Utifrån teori har vi formulerat tre hypoteser för att undersöka om vi kan finna indikatorer på hur kommunala och privata fastighetsbolag skiljer sig till från varandra. För att genomföra undersökningen har uppsatsen utgått från en kvantitativ metod och statistiska test har gjorts för att kunna analysera utfallen.Resultaten indikerar på att det finns en signifikant skillnad mellan kommunala och privata fastighetsbolag i två av hypoteserna.

Bilens förändrade förutsättningar i framtidens städer : en studie om aktuella förändringar kring privatbilismen i västvärlden och hur trafikplanering i Öresundsregion förhåller sig till rådande trender

Syftet med denna uppsats har varit att få en förståelse för vad pågående förändringar kring bilanvändning innebär för stadsplanering i västvärlden. Denna uppsats lämnar ingen lösning utan ska ses som inlägg i en pågående och högaktuell diskussion kring bilens roll i staden. För att uppnå detta syfte har en litteraturöversikt samt en intervjustudie med sju trafikplanerare från Köpenhamn, Malmö, Helsingborg och Lund genomförts. Bilen och dess normer har sedan 1950-talet präglat städer och stadsplanering. Bilism har i stor utsträckning bidragit till klimatpåverkan och urbanisering. Något som sin tur har resulterat i urbana fenomen som förtätning och stadsutglesning, påtagliga både i en global kontext och ner på nationell och lokal nivå.

Säkring av nettotillgångar i utländska dotterbolag - omfattning och samband

The translation of financial records of foreign subsidiaries gives rise to currency translation adjustments that affect total group equity. If unwanted, fluctuations in translation adjustments can be avoided using net investment hedges. This study aims to find the extent of net investment hedging in Sweden today and in a short historical perspective, and find explanations to varying levels of hedging and firms' decisions to hedge. Based on annual reports, we determine Swedish firms' net investment hedging policies and their level of hedging. The 32 largest companies listed on the Stockholm stock exchange in the years 1993, 2004, 2006, and 2009 are studied.

Integrerat växtskydd i svensk jordgubbsodling : attityder bland odlarna till genomförande av det nya direktivet

This study was conducted at VikingGenetics' bull breeding station in Falkenberg, Sweden. The bulls waiting for the results of their progeny testing at this station are either kept in group housing or individual housing. Since both of these housing systems have advantages and disadvantages, it was in the interest of VikingGenetics to know which of these housing systems is the best. The aim of this study was to investigate the welfare of the bulls in these two housing systems through behavioural observations and the use of activity monitors. In the preparations for the study 16 bulls, 8 in each housing system, were chosen.

Ögårdsparken - en gemensam park för olika kulturer genom aktivitet

Road safety is the result of measures to reduce therisk of accident and injury. (Nationalencyklopedin,2008). In principle, road safety means to arrive saveand sound.Safe traffic in cities is mainly achieved throughappropriate speed. In Sweden, more than half ofall rides happen with a speed above the legal speedlimit (Holmberg, Hydén m.fl, 1996). To reducespeed in order to increase safety requires measureswhich influence a driver?s motives for his orher choice of speed even if these are not rational(Boverket, 2002).

Effects of biogas residues on respiration and denitrification in arable soil : evaluation of methods, microbial activity and agronomic implications

Agricultural soils constitute the base in human food production and soil content of organic matter and plant nutrients together with soil microbial activity are all important parameters for high crop yield of good quality. These parameters are dependant on proper fertilization.Anaerobic digestion of organic wastes for biogas production generates a liquid residue called biogas residue (BR). It contains organic material and plant nutrients which makes ita potential fertilizer for arable cropping. However, it also contains heavy metals and toxic organic compounds and it is therefore in need of evaluation before usage.Microbial tests were performed aiming to evaluate the agronomic traits of four different BR and to find a viable procedure for evaluating slurry fertilizers. Two experiments where soil respiration and soil potential denitrification activity (PDA) was measured at fertilizer addition were performed.
