Tryptophan metabolic pathways and brain serotonergic activity: A comparative review
2019
The essential amino acid L-tryptophan (Trp) is the precursor of the monoaminergic neurotransmitter serotonin (5-hydroxytryptamine, 5-HT). Numerous studies have shown that elevated dietary Trp has a suppressive effect on aggressive behavior and post-stress plasma cortisol concentrations in vertebrates, including teleosts. These effects are believed to be mediated by the brain serotonergic system, even though all mechanisms involved are not well understood. The rate of 5-HT biosynthesis is limited by Trp availability, but only in neurons of the hindbrain raphe area predominantly expressing the isoform TPH2 of the enzyme tryptophan hydroxylase (TPH). In the periphery as well as in brain areas …
Experimental Investigation on Stiffness and Strength of Single-Lap Z-Pinned Joints in a Laminated CFRP Stress-Ribbon Strip
2016
Carbon fiber-reinforced polymer (carbon-polymer) is an advanced lightweight composite material with high strength and excellent resistance to corrosion and fatigue. Over the past decades, application of fiber-reinforced polymers has been spread from the aerospace to other branches of industry such as automobile and civil engineering. Unidirectional carbon-polymers have a high potential for replacing steel in tensile members. Recently, the first carbonpolymer stress-ribbon bridge has been constructed in Germany. The non-laminated strip-loop carbon-polymer thin strips were used as the load bearing components in this bridge. In comparison with the laminated components, the applied cables are c…
Autorreflexión pedagógica
2019
The autobiographical reflection on school learning makes it possible to explain how personal life guidelines are loading teaching activity with experiences. Educational time does not consist only of a linear narration, but works as the evocation of temporal and spatial memories of an explanation of the present. Personal life is intertwined with school reflection to give meaning to what we decide from teaching
The Radó–Kneser–Choquet theorem for $p$-harmonic mappings between Riemannian surfaces
2020
In the planar setting the Rad\'o-Kneser-Choquet theorem states that a harmonic map from the unit disk onto a Jordan domain bounded by a convex curve is a diffeomorphism provided that the boundary mapping is a homeomorphism. We prove the injectivity criterion of Rad\'o-Kneser-Choquet for $p$-harmonic mappings between Riemannian surfaces. In our proof of the injecticity criterion we approximate the $p$-harmonic map with auxiliary mappings that solve uniformly elliptic systems. We prove that each auxiliary mapping has a positive Jacobian by a homotopy argument. We keep the maps injective all the way through the homotopy with the help of the minimum principle for a certain subharmonic expressio…
Hva ønsker ungdommene med kroppsøvingsfaget i fremtiden?

Masteroppgave idrettsvitenskap ME517 - Universitetet i Agder 2019 The background of the project:From 2020 a new curriculum in physical education will be used. Several studies have been carried out where the researchers have come to the conclusion that a majority of the students enjoyphysical education as it is. These results made mecurious,andas a result, in my study I have agoal of searching in-depth within what the adolescent want with physical education in the future. Issue:«What do the adolescent want with physicaleducation in the future?» Method:My study was conducted using a qualitativ method with a phenomenological approach, and I conducted both observation and interview. The selecti…
Digitalisering i patologi : Hvilke faktorer mener patologer har størst betydning ved implementering av digital patologi?
2019
Masteroppgave helse- og sosialinformatikk HSI500 - Universitetet i Agder 2019 Diagnostic pathology is essential for diagnosing cancer and often also in guiding choice of treatment method. However many claim it has become a bottleneck within cancer treatment, due partly to the fact that the number of pathologists is not expanding in line with the increasing workload. Digital pathology (DP) is considered to be the solution for increased efficiency within the field of pathology.The implementation of health information systems is complex and involves technical, human and organisational aspects, and information systems of all types have consistently failed to deliver expected gains.In this study…
Skin surveillance attitudes and behaviors in relation to skin checks for early signs of skin cancer in a sample of secondary school students and teac…
2012
<p><strong>Background</strong>: Malignant melanoma (MM) can be readily treated in its earliest stages: survival rate, when detected early, is up to 95,0%. This justifies investigations on contributive factors and measures for precocious detection of skin tumors to improve early detection and to increase survival rates. The purpose of this survey was to collect information about knowledge, attitudes and behaviors on prevention in relation to skin checks for early signs of skin cancer on a sample of secondary school students and teachers.</p><p><strong>Methods</strong>: A sample of secondary school students and teachers from Palermo, was recruited usi…
Hautasaareke ihmistä varten : Jyväskylän Vanhan hautausmaan vaiheita vuosien 1956-1971 välisenä aikana
2014
Uskonyhteisöjen toimesta on perustettu hautausmaita, jotta yhteisöjen kuolleet jäsenet saadaan sijoitettua johonkin yhteisössä vallitsevien tapojen ja käytänteiden mukaisesti. Tämän tutkimuksen kohde, Jyväskylän Vanha hautausmaa perustettiin vuonna 1837 kehittyvän ja laajentuvan kaupungin laitamille huolehtimaan yhteisön edesmenneistä jäsenistä. Tässä tutkimuksessa tutkitaan Vanhan hautausmaan vaiheita vuosien 1956–1971 välisenä aikana. Tavoitteena on selvittää miten ja miksi hautausmaata pidettiin yllä konkreettisena tilana, ketkä sitä pitivät yllä ja miten siellä toimittiin suhteessa hautausmaiden tehtäviin. Kahteen aikaisempaan jaotteluun hautausmaiden tehtävistä sekä tutkimuskirjallisuu…
