Hva ønsker ungdommene med kroppsøvingsfaget i fremtiden?
2019
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…
Substituent effects on the mechanism changeover in a multipathway reaction: A model for the behavior of biological systems?
2009
By studying the rearrangement in dioxane/water of a series of (Z)-arylhydrazones of 5-amino-3- benzoyl-1,2,4-oxadiazole (1a-k) into the relevant (2-aryl-5-phenyl-2H-1,2,3-triazol-4-yl)ureas (2a-k) in a wide range of pS + (an operational scale of proton concentration in the mixed solvent used; dioxane/water, 1:1, v:v), the occurrence of three different reaction pathways (specific-acid- catalyzed, uncatalyzed, and general-base-catalyzed) for the relevant SNi process has been recently enlightened. The significantly different substituent effects on the three pathways cause some crossovers in the log kA,R versus pS + plots. Both the pS + value at which the crossover occurs and the width of the u…

2017
This article refers to criminal liability for performing aesthetic medicine treatment in a form of plastic surgery without patient’s consent, substitute consent (including collective) or substitute consent of Family Court. Article presents the current state of law in this respect and the correlation between applicable regulations of various branches of law and lex generalis regulations that deal with this issue, i.e. aesthetic medicine treatment.The author evaluates and describes the legal issues related with aesthetic medicine, including the patient’s consent, extended disclosure obligation as well as the ground for statutory liability for committing a prohibited act that is described and …
The structure of coronal plasma in active stellar coronae from density measurements
2005
We have analyzed high-resolution X-ray spectra of a sample of 22 active stars observed with the High Energy Transmission Grating Spectrometer (HETGS) on Chandra in order to investigate their coronal plasma density, using the lines of the He-like ions O VII, Mg XI, and Si XIII. Si XII lines in all stars of the sample axe compatible with the low-density limit (i.e. n(e) = 10(30) erg/s); O VII lines yield much lower densities of a few 10(10) cm(-3). Our results indicate that the "hot" and "cool" plasma resides in physically different structures. Our findings imply remarkably compact coronal structures, especially for the hotter (similar to 7 MK) plasma emitting the Mg xi lines characterized by…
A Randomized Controlled Trial Protocol for Using an Accelerometer-Smartphone Application Intervention to Increase Physical Activity and Improve Healt…
2021
Physical activity is beneficial for improving health and reducing sick leave absences. This article describes a protocol for an intervention using an interactive accelerometer smartphone application, telephone counselling, and physical activity recordings to increase the physical activity of workers in the military and improve their health. Under the protocol, employees from six military brigades in Finland will be randomly assigned to intervention and control groups. The intervention group’s participants will use accelerometers to measure their daily physical activities and their quality of sleep for six months. They will receive feedback based on these measurements via a smartphone applic…
Motives for competitive sports participation in masters track and field athletes : Impact of sociodemographic factors and competitive background
2022
Objectives Masters athletes due to their lifelong engagement in sport represent a unique group to study motivation for regular physical activity, but there is less scientific data on the sport motives in masters athletes. Therefore, the aim of this study was to evaluate the association of age, sex, education, nationality, competitive background and training amount with sport motives of masters track and field athletes. Methods 811 (254 women) athletes aged 35–89 years participated in European Veterans Athletics Championships in the year of 2000. Sport motives were assessed with a questionnaire and categorized into1) well-being, 2) competitive and performance 3) health and fitness motives. R…
Outdoor Mobility and Use of Adaptive or Maladaptive Walking Modifications among Older People
2020
Background. In old age, decline in functioning may cause changes in walking ability. Our aim was to study whether older people who report adaptive, maladaptive or no walking modifications differ in outdoor mobility. Methods. Community-dwelling people aged 75–90 years (N=848) were interviewed at baseline, of whom 761 participated in the 2-year follow-up. Walking modifications were assessed by asking the participants whether they had modified their way of walking 2 kilometers due to their health. Based on the responses, three categories were formed: no walking modifications (reference), adaptive (e.g., walking more slowly, using an aid) and maladaptive walking modifications (reduced frequency…
Effects of overnight military training and acute battle stress on the cognitive performance of soldiers in simulated urban combat
2022
Understanding the effect of stress, fatigue, and sleep deprivation on the ability to maintain an alert and attentive state in an ecologically valid setting is of importance as lapsing attention can, in many safety-critical professions, have devastating consequences. Here we studied the effect of close-quarters battle (CQ battle) exercise combined with overnight military training with sleep deprivation on cognitive performance, namely sustained attention and response inhibition. In addition, the effect of the CQ battle and overnight training on cardiac activity [heart rate and root mean square of the successive differences (RMSSD)] during the cognitive testing and the relationship between ca…
Changes in Physical Performance During 21 d of Military Field Training in Warfighters
2018
Introduction: Few studies have reported the amount of physical activity (PA) and its associations to physical performance of warfighters during military field training (MFT). The purpose of this study was to investigate changes in neuromuscular performance and PA among male Finnish Army conscripts during a 21-d MFT and to evaluate their recovery during 4 d after MFT. Methods: Body composition and physical performance were measured four times during the study (before MFT (PRE), after 12 d (MID), post training (POST) and after 4 d of recovery (RECO)). PA was measured throughout MFT in a group of healthy young male conscripts (n=49) by using a tri-axial accelerometer. The study was approved by…
Thiol-Stabilized Atomically Precise, Superatomic Silver Nanoparticles for Catalyzing Cycloisomerization of Alkynyl Amines
2018
Abstract Both the electronic and surface structures of metal nanomaterials play critical roles in determining their chemical properties. However, the non-molecular nature of conventional nanoparticles makes it extremely challenging to understand the molecular mechanism behind many of their unique electronic and surface properties. In this work, we report the synthesis, molecular and electronic structures of an atomically precise nanoparticle, [Ag206L72]q (L = thiolate, halide; q = charge). With a four-shell Ag7@Ag32@Ag77@Ag90 Ino-decahedral structure having a nearly perfect D5h symmetry, the metal core of the nanoparticle is co-stabilized by 68 thiolate and 4 halide ligands. Both electroche…
