Undersökning av svetsförband med avseende på svetsgeometri, diskontinuiteter och blästring med stålkulor
Breakdowns of welded structures are usually a consequence of fatigue loading. Fatigue fractures are commonly initiated in the region close to the weld toe but can also initiate from the weld root and from discontinuities inside the weld. The purpose of this investigation was to examine the weld quality of welded joints produced at Volvo Wheel Loaders factory in Arvika. The goal of the investigation is to give a clearer insight regarding factors influencing the fatigue strength of the welded joints and thereby give a better foundation for fatigue strength calculations.The investigation is including examination of the weld geometry, weld discontinuities and the effects of shot peening. Mainly three different methods for collecting test data have been used: Plastic replicas cast on the weld profile, weld specimens from a rear frame belonging to a wheel loader of model L110E/120E and Almen testing of the shot peening.The results showed that it is not possible to control even transition between the weld material and the base material without after treatment.
O/ändliga o/möjligheter i Kathy Ackers Great Expectations och Alison Knowles The Big Book
In this paper I'm trying to trace, analyze and emphasize Kathy Acker?s Great Expectations and Alison Knowles?s The Big Book in regard to the books in/finite im/possibilities. I analyze them through historical changes in the books format and structure, especially ones proposed by Mallarmé, Duchamp and Fluxus. To analyze the texts more closely attention is directed to how Acker and Knowles challenge the conventional narrative, in regard to the body and language/voice and sound. I give specific emphasizes to thoughts posted by écriture féminine, while also adding Mara Lee?s temporalities in regard to body resistance and time.
Inclusion Body Disease hos boa- och pytonorm : diagnostiska metoder
Inclusion body disease (IBD) affecting boas and pythons is a serious and common disease. Boas can be clinically healthy carriers, which makes control of the disease difficult. The causative agent has not yet been confidently identified, and therefore there are no serodiagnostic tests available. Today, histopathologic examination of tissue biopsies is the recommended antemortem diagnostic method, but there are several disadvantages. The objective of this study was to compare the sensitivity of two diagnostic methods ? liver biopsies and blood smears, and to evaluate ultrasoundguided needle biopsy of the liver.
Stärkelsers funktion som konsistensgivare vid olika temperaturer i pulversoppa : en experimentell kvantitativ studie
More often consumers demand instant dry soup that can be prepared with a water temperature below 100o C, which is currently not possible, because the dry soup becomes too thin when using water with a lower temperature. In this study, various kinds of starch studies were made to optimize the starch used in the existing product to make it more viscous at both high and low temperatures. The result was that one of the two starches present in the existing product was retained by change in quantity as it contributed to important flavor parameters. The second was removed and replaced with a starch that made the product more viscous at lower temperatures. To find out if the new product differed from the existing product a viscosity measurement and a sensory paired preference test were made.
Hur rör sig polisens tjänstehundar? : en pilotstudie gällande tjänstehundars rörelsesymmetri mätt med tryckmätningsmatta
SammanfattningBakgrundDet är i Sverige svårt att tillgodose behovet av cirka 450 tjänstehundar och gällande hälsa är uppfattningen bland användarna att hundarnas fysiska hållbarhet blivit sämre. Med hänsyn till att det lider brist på tjänstehundar och att de tas ur tjänst tidigare än önskat vore det av stort värde att kunna förlänga en polishunds tjänstgöringstid. Ett sätt att förverkliga detta kan vara att använda undersökningstekniker vilka tidigt kan fånga upp lindriga förändringar i rörelsesymmetri, förändringar som kan vara ett första tecken på smärta. En tryckmätningsmatta kan registrera små förändringar i hur hunden belastar sina ben, förändringar som är svåra att se med blotta ögat. Det kan därför vara av intresse att ta fram ett normalmaterial för tjänstehundar så att det med tryckmätningsmattans hjälp tidigt går att upptäcka om en stoisk tjänstehund har ett förändrat rörelsemönster.Syfte & hypotesSyftet var att använda en tryckmätningsmatta för att skapa ett normalmaterial för en tjänstehundspopulation gällande parametrar registrerade med tryckmätnings-mattan.
Jämförelse av vertikala krafter mellan hov och underlag vid nedsittning och lättridning i trav hos häst :
Equestrian sports and the interest in horses have existed for hundreds of years. It is only in the last thirty years the technological development have enabled closer studies of equine locomotion. The production of both soft- and hardware that manages to capture and analyze the fast movement of the horse has resulted in a large increase in locomotion research.
Even though the interest in horses and the different disciplines they compete in is great, there is a small understanding in how the rider influences the movement of the horse in different types of training.
There are several studies available where horses moving freely without the influence of a rider have been studied. What happens with locomotion and ground reaction forces when a rider and equipment are added is not well studied.
The objective of this study was to investigate if there are any differences in the ground reaction forces between sitting and rising trot.
The study contained seven horses. Six Grand Prix dressage horses and one dressage horse competing at intermediate level.
Varför fortsätter rökare att röka och vad motiverar till ett rökstopp? : en kvalitativ studie
This study aimed to describe children?s experience of living with overweight or obesity, by using a literature-review. The study includes eleven articles, data is from children between ages 5-15 year. The result occurring were in the areas; Quality of life and self-esteem, Social company, Body concept and weight reduction and Psychological unhealth. BMI above what is recommended gives a negative influence on quality of live and self-esteem.
Gymnasieelevers attityder till det rådande skönhetsidealet : en kvantitativ studie
The purpose of the study was to inquire into pupils? attitude towards the current beauty ideal from a gender- and an ethnicity perspective. The study was based on a quantitative survey among 116 young students about prevailing beauty ideal from two different schools in the Stockholm area. The result showed that the students are partially characterized by the stereotyped images of women and men but that there are tendencies towards another view especially among the girls. It is however clear that appearance still is important.
MAXIMAL STYRKA I ENBENSKNÄBÖJ KORRELERAR MED ACCELERATIONS KAPACITET OCH AGILITY
Starka samband har tidigare framkommit mellan den maximala styrkan i knäböj på två ben och sprintkapacitet rakt fram på varierande distanser men inte på sprintkapacitet i agility. Gemensamt för de flesta studier är dock att styrketesterna endast utförts på två ben.Syftet med studien var att undersöka korrelationen mellan maximal styrka i enbensknäböj i smith-maskin och sprintförmågan i löpningar, både rakt fram och med riktningsförändringar.Testgruppen bestod av 19 män (23,9 ± 2,5 år) med regelbunden träningserfarenhet av intermittenta lagsporter. Sprinttester gjordes på 5, 10 och 20 meter rakt fram samt ett zigzag agilitytest för att testa sprintkapacitet med riktningsförändringar. Enbensknäböj i smith-maskin genomfördes med stången på axlarna och ett djup på 110 grader vinkel mellan femur och tibia.Resultaten av studien visade på signifikanta korrelationer mellan den maximala styrkan i enbensknäböj och sprintkapaciteten på 5 och 10 meter samt i agility. När den maximala styrkan var relaterad till kroppsvikten hittades signifikanta korrelationer mellan 5 och 20 meter samt i agility.
Ser jag ut som ett monster eller har jag BDD? : Fem kontrollerade fallstudier av exponeringsbehandling vid Body Dysmorphic Disorder.
SammanfattningBody Dysmorphic Disorder (BDD) karaktäriseras av en fixering vid en inbillad defekt i utseendet. BDD leder till påtagligt lidande och svårigheter att fungera i vardagen. Diagnosen förknippas med depressivitet, social ångest och hög suicidrisk. Syftet med studien var att under svenska förhållanden prova en behandling bestående av exponering med responsprevention (ERP) och monitorering på patienter med svår BDD-problematik. I single-case designer av 5 patienter undersöktes effekten av ERP som specifik faktor utöver terapeutnärvaro och monitorering.
Arbetsprov i fält på ridhästar
Sport horses are widely used for performance in jumping, dressage, endurance etc. To enable comparisons of horses, training facilities, programs or physical status, an exercise test can be used. Exercise tests are also important to increase knowledge about exercise physiology of the horse considering different ways of training to compare training methods or individual qualities, development of an individual or other investigations of equine exercise physiology. Since several investigations are done on standard- and thoroughbred horses but less on sport horses, it is of great importance to get an overview of the investigations done. Most common is to investigate heart rate and lactate concentration.
Ageism: A literature review
Background: The studies analyzed have shown among other things that ageism appears to be an overlooked category in intersectionality studies, elderly is offered care in worse conditions than non-elderly and stereotypes restrict elderlys social space to act. The gray tsunami is approaching but studies show that large gaps separate different agegroups.
Aims: The study discuss how scientists reason about ageism towards elderly in a social science discussion.
Method: A literature review was conducted in which fifteen articles were analyzed. The database used, is the librariescatalog Summon, at Malmö University. The articles was compiled in themes to give dilated clarity in ageisms complexity towards elderly. The results are being discussed on the basis of terror management theory, gerotranscendence and social identitity theory.
Results: Elderlys relation to society's expectations about aging can affect a self/body-dualism, a split.
En undersökning om fallolyckor med gångtrafikanter
The purpose of this study was to investigate different relations between the damages of falls and background variables as well as the relation between the falls and the weather condition to later be able to use this report to expand the knowledge among workers at VTI about the pedestrian fall injuries. All of the fall injuries in the data that this study is based on have occurred in Sweden during the time period between January 2003 and December 2011.To be able to answer the questions that this report is based on several statistical methods are used. The statistical methods that have been used during the making of this report are multiple linear regression, binary logistic regression, correlation analysis, association analysis and descriptive statistics as well as visual analysis.The results of the study show that women around menopause age have a tendency to get a big increase in the amount of injuries compared to men of the same age. The study also suggests that men on average tend to have a lower level of injury compared to women.Age also seems to affect both the amount of injuries and the level of injury negatively. The study suggests that the most likely reason for this is both that the intake of ?Fall Risk Increasing Medicine?, which is medicine that increases the drowsiness, is higher among older individuals as well as lower estrogen levels among older women and lower amount of testosterone among older men, which causes a loss of bone density in both sexes.The weather seems to have a strong effect on how many injuries occur but also a noticeable effect on the scale of the injury.
Inokulering med två hjorttryfflar på arginingödslade täckrotsplantor i Gideå plantskola :
The effect of inoculation on containerized pine and spruce seedlings in a nursery with two
ectomycorrhizal fungi was investigated in regard to the development of mycorrhiza and plant growth. The fungi were Elaphomyces muricatus and Elaphomyces granulates and the inoculated seedlings were compared to an uninoculated control. These seedlings were all fertilized with arginine.
Five mycorrhiza species were found after DNA sequencing of the mycorrhizal root tips with different found morphotypes on seedlings from all treatments. Thelephora terrestris was the type which had the greatest distribution on pine seedlings and Tylospora asterophora was found at big extent on spruce seedlings. The inoculated species was not found, if it was due to the species hadn?t colonized the roots or if the DNA sequencing failed we can only speculate about.
En jämförelse avseende beståndsgående-och stickvägsgående gallringsmaskiner
The purpose of this report is to investigate and compare the difference between stand-thinning machines and strip-road thinning machines, and how they affect the stand on behalf of future growth, theoretical economic result, wind impact, snow pressure and density of stand.
The investigation is regarding the first commercial thinning of pine stands, after pre-commercial thinning that was well conducted.
The investigation area was located near Katrineholm, Sweden. The measurements that were measured were strength of thinning and amounts of wind throws, snow-breaks and hauling damages.
The results that emerged, was that thinning with strip-road machines had a significantly higher strength of thinning over all, as compared with the stand- thinning machines (45 percent versus 30 percent).
Comparisons between wind-throws, snow-breaks and hauling damages of the stand could not establish any significant differences between the two methods that were investigated.
Conclusions, over all, were that if forest owners want to have more timber volume left for second thinning and final cut of the stand, the forest owners should choose the method with stand-thinning machines. From the point of view of gentle treatment of the stand and ground damages the choice should be the same.
However, the method with strip-road thinning machines is the most common and accessible method in Sweden. Most likely it is the most economical way to manage the stand for forest owners in present time.
If the method with stand-thinning machines is becoming more common in Sweden, it is suggested for forest owners to consider the stand-thinning method as a candidate for treatment due to economic aspects..
