Validering av smärtformulär för katt
The objective of this study was to assess validity and reliability for five different owner-completed instruments evaluated to assess chronic musculoskeletal pain in cats. All of the instruments were questionnaires, three asking about behavioral changes, one about the degree of pain and one about quality of life. One of the instruments was written originally in Swedish, the other four instruments were translated into Swedish before use.
Data available were records from 57 cats with no signs of pain and 11 cats with different pain-related diagnoses. The diagnoses were ensured by clinical examination including palpation and manipulation of joints, gait testing on a force-plate and X-ray scans. Instrument 1 was completed by 57 pain-free and 11 pain-affected cats.
Uttag av energisortiment vid gallring av contorta, ett komplement till konventionell gallring? :
A recommendation for stand treatment of lodgepole pine (Pinus contorta) is, in a scientific point of view, lacking when it comes to harvesting for biomass energy. Within the next decades it is expected that 280 000 hectares of lodgepole pine will have reached thinning age on the domains of Svenska Cellulosa Aktiebolaget (SCA). Due to this the interest has grown rapidly for studying the possibilities of harvesting biofuel assortments already in the first thinning.
In this study the distribution of the biomass within lodgepole pine trees has been studied and taken into account for estimating the proportions of harvested assortments when using different methods of thinning. The methods studied were conventional biofuel-harvesting (with delimbed branches gathered separately from the round wood) and thinning with cutting of round wood and long tops (incl.
Kan biologisk mångfald ökas i ett avsatt skogsområde? : skötselplan för Storskogsberget på Holmen skogs marker, distrikt Umeå
The biodiversity of the Swedish forest has degenerated since the beginning of the 19th century when fire suppression and large scale logging first occurred. Together with a changed land use, these actions today have had a negative influence on many forest dwelling species, due to gradual reduction of natural processes, successions and different structures from the forest ecosystem. The Swedish Forest Act, together with different environment certifications, have today encouraged private persons and forest companies, among them Holmen Skog, to work actively to improve nature conservation. The aim of this study was to, by field inventories of already existing nature values, literature studies, recommendations from scientific reports and ecological gap analysis as a basis, make a management plan, for a non-production area, to conserve or improve the prerequisites for biodiversity. ?Storskogsberget? is located in the coastal area of Västerbotten County, 35 km from the city of Umeå.
Flytande sågklassläggning på Iggesunds sågverk
Syftet med denna studie är att beräkna de ekonomiska konsekvenserna för Iggesunds sågverk att övergå från diameterbaserad sågklassläggning, som används i dagsläget, till flytande sågklassläggning för delar av sågverkets timmerkurva. Huvudfrågeställningen indelades i olika delfrågor som undersökte hur volym- och värdeutbytet, planerbarheten och produktiviteten påverkades. Studien grundar sig på teorier om den ekonomiska konsekvensen av ett beslut där resonemang om alternativkostnaden ingår, volym- och värdeutbyte av råvaran samt teorier om produktion, produktivitet och planerbarhet.
Studiens resultat kommer att användas av Iggesunds sågverk i ett fortsatt utredningsarbete om effekterna av flytande sågklassläggning på hela timmerkurvan. Till detta utredningsarbete har en metodik utformats och ett rekommenderat arbetssätt presenteras i kapitel 7.
Konstruktion av infästning till dysa
The goal of this thesis is to design an attachment between a duct and a pod. A pod is what could be compared to an outboard engine for larger vessels. The pod is placed on the outside of the ship?s hull and can rotate 360 ?. A duct is a large steel ring that can be placed around the propeller on the pod to increasethe propulsion force of the ship in lower velocities.
Skogens produktionsvärden och dess betydelse för Sveriges ekonomi
The forest is characterized by many different values such as those related to forest productivity which are of a big importance for Swedish economy. History has proved that forest resources had helped the country in the transition from the agricultural to the industrial society. Today Swedish forest industry is among the strongest in Europe and significantly contributing to the Swedish export. The industry provides many direct and indirect job opportunities and is one of the biggest employers in the industry sector. It is also worth to notice that the forest can also generate an additional income for the owners, even if the forestry isn?t their primary income source.
Sjuksköterskans stöd till vuxna patienter med rheumatoid artrit - empirisk studie på reumatologmottagningar
Background: Rheumatoid arthritis is a common disease worldwide. The disease is described as a chronic inflammation that afflicts mainly the joints, the tendrons and the synovial joint. The inflammation breaks down cartilage, ligaments and bone. When the patient gets the diagnosis he/she frequently reacts with chock, denial or/and dissociation. Active support from the nurse can have an important impact on the patient in accepting and processing that he/she suffers from disease.
Älgens barkgnag på granstammar : omfattning med avseende på geografisk utbredning, skadad volym och ekonomiska konsekvenser
In three areas in the province of Småland studies has been done to investigate how big
damage the moose may do to P. abies. An inquiry examination and two different types of
surveys were done to find out how big area, which volume and which financial consequences
the moose debarking has had on the forest.
When the volume was calculated the rot spreading was included. The area that was damaged
was stipulated with the answers from the inquiry examination. 59 % of the asked forest
owners answered the inquiry.
Upptryck : En jämförelse mellan RIDAS och internationella riktlinjer
Old hollow trees of oak contain a large amount of wood mould. Unfortunately, these trees have in the last century been greatly reduced in numbers. It has resulted in that species that depend on these habitats, saproxylic species, have become at risk to decrease in numbers or die out regionally. Previous studies have shown that the volume of wood mould is an important factor for occurrence and population size of saproxylic organisms. The aim of the present study was to examine how the volume of wood mould varies among ash (Fraxinus excelsior), lime (Tilia sp.), maple (Acer platanoides), aspen (Populus tremula) and oak (Quercus robur).

The effects of mother trees and site conditions on the distribution of natural regeneration establishment in a Bornean rainforest disturbed by logging and fire
In the tropics, logging and wild fire can result in degraded secondary forests with lower biodiversity than in the natural forest. One way to limit forest degradation is to rehabilitate the present large areas of secondary forests. However, there is a lack of knowledge concerning the ecology of tropical tree species and further studies would be advantageous for future rehabilitation efforts of degraded rainforest. The objective of this study was to investigate how mother trees in secondary forest and different site factors affect the abundance and spatial distribution of natural regeneration of non-pioneer tree species in a tropical rainforest in Sabah, Malaysia.
The study took place in the INIKEA Forest Rehabilitation Project area, which suffered from wild fire in 1983 and has been selectively logged over both before and after the fire. Natural regeneration and site variables were inventoried in plots, while mother trees were inventoried in the whole survey area.
Vi i individualismens samhälle? : En studie över fackföreningsorganisationens ställning i det individualistiska samhället
In Sweden, the labour movement historically had influenced both society and politics. In recent times, it is considered a change in society with a stronger employer party while the unions weakened by reduced unionisation. This study aims to highlight the presence of individualistic and collectivistic approaches to the labour market in relation to union density. The different approaches are investigated in the labour market by means of a quantitative survey. The study's survey items are workers in the timber industry.

Utvärdering av autologt konditionerat serum :
Joint injury (inflammation) or osteoarthritis is the most common cause of poor performance in the athletic horse. Osteoarthritis is the ensuing degeneration of joint cartilage due to inflammation/injury. The single most important factor in the inflammation cascade of joint injuries is interleukin-1 (IL-1). Until recently, these injuries have been treated with products like hyaluronic acid, cortisone and polysulphated glycosaminoglycans (PSGAG).
Several studies have not been able to demonstrate a significant difference in the clinical improvement of joint injuries treated with hyaluronic acid or PSGAG and saline.
