… of pigs but not so much on the genetic effects has been performed. The frequency of tail biting in pig farms influence among others of environment enrichment, ventilation, gender and breed of the pig. The space the pigs have to access in the pen should not be too large and not …
… stock and facilitates logistics. Figures from Holmen Skog show low reporting frequency. The purpose of this study is to investigate the reason and find suggestions for improvement. A total of 17 machine operators were interviewed using a questionnaire combined with open …
The objective was to examine the frequency of unwanted behaviors in the Swedish feline population and what factors in the environment, inheritance and past life that have an influence on the frequency. SLU’s web poll generator was used to create a web poll which insinuated that …

Design, simulering och experimentell verifiering
… verification shows that the state estimates can be highly accurate for medium frequency motions, ranging from 3-30Hz. For this interval the estimate were also robust to model inaccuracies.The estimation of low-frequency motions was relatively poor, due to problemswith drift for …
… The protection system can only compensate automatically for the fundamental frequency (50Hz), and manually for the 3rd, 5th, 7th and 9th harmonics. In most cases, when the harmonics are very small it is not necessary to compensate for them. There are though cases when …
a comparison between high and low Norway spruce and birch stumps : a measuring of the efficacy of Phlebiopsis gigantea stump treatment
… of this study was to investigate if there were any differences in infection frequencyfrom airborne Heterobasidion spp. spores depending on whether the stump height is high (1 m) orlow (15 cm) in pre?commercial thinnings in the southern Sweden. The efficacy of stump treatment …

… damage monitoring in 2007 and 2008. We investigated if the presence and frequency of Resin-top disease increased with better ground cover vegetation (indicating better productivity) and more moist soils, and how a combination of these two site factors affected the presence and …
… The second aim was to examine what type of object stimulated the highest frequency of interaction. The study was carried out at the Swedish Livestock Research Centre in Lövsta where a batch of litters from 10 first-parity Yorkshire sows were used. Sow and piglets were housed in …
… the possibility of connecting two of the mined vein systems, VLF (Very Low Frequency) electromagnetic measurements were performed across the strike of a possible continuation between the Vegerbol and Karlsbol deposits. The VLF survey showed a significant anomaly where such a …
<em>Ett modernt dimensioneringsproblem för huskonstruktörer</em>
… Abaqus. In the simulations, the influence of various factors on the natural frequency of floor-systems and the acceleration level caused by dynamic loads, is studied. Properties like elastic modulus, span width, boundary conditions, density, slab thickness and placement the load …
… allophones of five Swedish vowels. Formants, vowel duration and fundamental frequency were measured for the three closest and the three furthest from native pronunciation rated L2-learners. The results indicate that a class in Swedish pronunciation significantly decreased the …
… staff on time to move pigs and the methods used for moving. Staff differed in frequency of touches to animals, the proportion of paddle use that ended in physical contact with the pigs and the force of touches to pigs. There was a trend towards touches of less force to be more …
Energibesparingsåtgärder vid blekeri 4 & 5 med jämförelse mot ny utrustning
… were conducted to be comparable. Quotation of the pumps assumes the use of frequency inverters. A deeper investigation was made for 441PU255 which is located at bleaching plant 4. The drop leg level of the pump is controlled via a throttle valve. A frequency inverter is …
… 4th 2014.Selection criteria: Randomized controlled trials measuring stool frequency in chronically constipated children on a cow’s milk-free diet were included. The children should not have an allergy to cow’s milk or organic constipation. The articles should be written in …
