Non-linear analysis of plane steel prestressed truss in fire
2002
The concept of analysis of 2-D static loaded prestressed steel trusses till failure during fire using a modified method of forces is presented. Failure of steel trusses in fire is based on the criterion of stresses. Behaviour of steel is described by non-linear constitutive model (based on hypo-elastic Ramberg-Osgood formula and Dorn creep theory) and Plem proposition (for string). Both models are approximated in calculations by hyperbolic Norton-Bailey rule. Fire simulates thermal force as an action of high temperature that increases linearly up to some level. The complete formulation of this method is illustrated by the algorithm of model parameters identification. Analysis of results for…
Specific distribution of cross-sectional area in each hamstring muscle of sprint runners and relationship between those and sprint performance

Betydningen av TARGET-modellens klimastruktur i kroppsøving på elevers opplevde motivasjonsklima og målorientering : En intervensjonsstudie i kroppsø…
2017
Master grunnskolelærerutdanning for trinn 5-10, 5-årig masterprogram IDR507 - Universitetet i Agder 2017 Hensikten med denne studien var å undersøke om kroppsøvingslæreren kunne ha umiddelbar påvirkning på ungdomsskoleelevers opplevde motivasjonsklima, og om dette ville lede til endringer blant elevenes målorientering. Studien er en intervensjonsstudie med et cross-over design. Utvalget består av 53 respondenter som går på 9.klassetrinn ved en skole i Vest- Agder. Utvalget består av 50,9 % gutter og 49,1 % jenter. Denne studien benytter seg av TARGET-modellen som rammeverk for utforming av to undervisningsopplegg som skal representere tydelig prestasjonsorientert og tydelig mestringsoriente…

Masteroppgave i idrettsvitenskap - Universitetet i Agder 2016 Studies that have looked at the relationship between training and performance have sown that athletes must practice at lot in order to reach a high level (Côté et al., 2007; Ericsson et al., 1993; Simon & Chase, 1973), and motivation is viewed as an important factor in order to implement the required training. Through satisfaction of the basic needs of autonomy, competence and relatedness, athletes will feel self-determination and intrinsic motivation (Deci & Ryan, 1985). Furthermore, football players who spend more time promoting their own learning is often preferred over players taking less responsibility (Toering et al., 2012)…

Dissimilar titanium-aluminum skin-stringer joints by FSW: process mechanics and performance
2022
Ever since its inception, friction stir welding (FSW) is being validated by scientific investigations as an effective substitution for fusion-based conventional joining technologies. One of the main strengths of FSW is the possibility to produce dissimilar joints, even using materials extremely different in terms of thermal and mechanical properties. The goal of the present research is to investigate the feasibility of both Al-Ti skin-stringer and reversed Ti-Al skin-stringer joints, highlighting the effect of joint configuration and main process parameters on material flow and joint mechanical properties. During the investigation, the essentiality of the proper heat input through balancing
Estudio del mecanismo de reacción e inhibición de cisteína proteasas mediante métodos multiescala
2022
En esta tesis doctoral se realizaron estudios computacionales para las enzimas caspasa-1 y la 3CLpro del SARS-CoV-2. Estas enzimas pertenecen a la familia de las cisteína proteasas, las cuales hidrolizan sus respectivos sustratos rompiendo un enlace peptídico en particular. En esta reacción interviene una diada catalítica conformada por un par Cis-His. La caspasa-1 fue seleccionada debido a su importancia farmacológica en la enfermedad de Alzheimer, y la enzima 3CLpro del SARS-CoV-2 por estar involucrada en el proceso de replicación del virus responsable de la enfermedad del COVID-19. Para ambas se realizaron estudios que ayudaron a racionalizar el mecanismo de reacción con su sustrato natu…
Sammenhengen mellom mestringsforventning, helserelatert livskvalitet og selvrapportert fysisk aktivitet blant elever i videregående skole
2016
Masteroppgave folkehelsevitenskap - Universitetet i Agder 2016 Background: Two different intervention models were developed to increase participation in physical education in high school, targeting “motion enjoyment” and “sport enjoyment”. Both models are intended to increase the pleasure of physical activity in physical education, as well as to contribute to the development of students’ skills, abilities and increase future commitment. The intention behind the motion enjoyment model is to reinforce positive experiences which are related to physical activity, along with raising the awareness in young people of the health benefits associated with physical activity. The sport enjoyment model …
How does a simulated soccer match affect regional differences in biceps femoris muscle architecture?
2017
Soccer is played by thousands of athletes across the globe and its participation increases the overall risk of injury, in particular, hamstring strain injuries (HSI). Biceps femoris (BF) has been shown to be involved the in 5 out of 6 HSI cases and risk factors including fatigue and short BF fascicle length (FL) have been identified. Furthermore, previous studies suggest that different muscle regions may undergo different strains during dynamic tasks, which could contribute to injury risk. The primary aim of this study was to evaluate the effects of a soccer match on regional differences in the BF muscle architecture. A secondary aim was to assess the reliability of the extended field of vi…
