Application of Electronic Nose for Evaluation of Wastewater Treatment Process Effects at Full-Scale WWTP
2019
This paper presents the results of studies aiming at the assessment and classification of wastewater using an electronic nose. During the experiment, an attempt was made to classify the medium based on an analysis of signals from a gas sensor array, the intensity of which depended on the levels of volatile compounds in the headspace gas mixture above the wastewater table. The research involved samples collected from the mechanical and biological treatment devices of a full-scale wastewater treatment plant (WWTP), as well as wastewater analysis. The measurements were carried out with a metal-oxide-semiconductor (MOS) gas sensor array, when coupled with a computing unit (e.g., a computer with…
Instrumental Odour Monitoring System Classification Performance Optimization by Analysis of Different Pattern-Recognition and Feature Extraction Tech…
2020
Instrumental odour monitoring systems (IOMS) are intelligent electronic sensing tools for which the primary application is the generation of odour metrics that are indicators of odour as perceived by human observers. The quality of the odour sensor signal, the mathematical treatment of the acquired data, and the validation of the correlation of the odour metric are key topics to control in order to ensure a robust and reliable measurement. The research presents and discusses the use of different pattern recognition and feature extraction techniques in the elaboration and effectiveness of the odour classification monitoring model (OCMM). The effect of the rise, intermediate, and peak period …
Influence of Polymer Electrospun Nanofibers on Thermal Properties of Epoxy Resins
2019
Electrospinning of polymers has gained surging interest in the last decades due to its wide range of applications in different fields, such as sensors, electronic devices, separation systems, biomedical materials. Still there are only few reports on the use of these nanofibers as reinforcement in polymer composites. In this paper, solution electrospinning was employed to produce nanofibrous mats impregnating two epoxy resins to form “monolayer“ systems, with the aim to study the influence of the nanofibers on both the curing behaviour and the morphology of the resin systems. Three polymers were chosen for producing electrospun mats, a polysulfone (PSF), a polyamide Nylon 6,6 (Ny66) and a po…
A Qualitative Exploration of Collective Collapse in a Norwegian Qualifying Premier League Soccer Match—The Successful Team's Perspective
2022
The current case study focused on a crucial match in the qualification for the Norwegian Premier League (Eliteserien). In the match, the participants of the study experienced a radical change in performance toward the end of the second half, from being behind by several goals to scoring 3 goals in 6 min and winning the qualifying game. The purpose of this study was therefore to examine the perceptions and reflections of players and coaches (sporting director) on what occurred within their own team and within the opposing team. The momentum shift in the opposition team can be described as a collective collapse. In the study, the theoretical collective collapse process model was used as a gui…
La participación de la ciudadanía en los procesos de diseño de las políticas públicas de empleo. El caso del litoral sur de Alicante
2019
La presente investigación tiene como finalidad describir cómo la ciudadanía ha contribuido a la elaboración de un Diagnóstico Territorial de Empleo (DET) promovido por la Generalitat Valenciana, previo al diseño de futuras políticas públicas para el fomento del empleo, en tres municipios alicantinos. Se consiguió a través de una Investigación-Acción-Participación (IAP). Se realizaron talleres participativos y grupos focales que sirvieron para que la ciudadanía conociese de la existencia del proyecto y sus fines, además de aportar su experiencia, opinión y plantear posibles soluciones a la problemática del empleo en estos municipios. Se puede concluir que la ciudadanía está capacitada para a…
Method and apparatus using selected superparamagnetic labels for rapid quantification of immunochromatographic tests
2009

The principle and performance of the method was demonstrated by measuring the levels of human chorionic gonadotropin (hCG) present in urine. The test format was a sandwich assay using two distinct monoclonal antib…
Risk of Low Energy Availability, Disordered Eating, Exercise Addiction, and Food Intolerances in Female Endurance Athletes
2022
Relative energy deficiency in sport (RED-S) is a complex syndrome describing health and performance consequences of low energy availability (LEA) and is common among female endurance athletes. Various underlying causes of LEA have been reported, including disordered eating behavior (DE), but studies investigating the association with exercise addiction and food intolerances are lacking. Therefore, the aim of this cross-sectional study was to investigate the association between DE, exercise addiction and food intolerances in athletes at risk of LEA compared to those with low risk. Female endurance athletes, 18–35 years, training ≥5 times/week were recruited in Norway, Sweden, Ireland, and Ge…
Comparison of condensed versus noncondensed cycling test methods and correlation to a 185 minutes’ indoor race simulation
2017
Master's thesis Sports Science ME517 - University of Agder 2017 Background: The validity of a currently used condensed indoor test protocols (C-TP) as measurement of competitive cycling performance is questioned. Purpose: C-TP contain testing of wattage at lactate threshold (LTW), maximum oxygen consumption (VO2max) and a Wingate anaerobic test (WAnT), performed consecutively during one session. As comparison these tests were separated and performed individually over three consecutive days, giving a non-condensed test protocol (NC-TP). The results were compared to a 5min all-out cycling test (5min all-out) performed individually and as part of a 185 minutes’ race simulation. Method: During …
Prevalence and associations of injury and illness among high school elite sport-students in the south of Norway
2018
Master's thesis Sports Science ME517 - University of Agder 2018 Introduction Youth participating in sports are often associated with a healthy lifestyle, however illness and injuries are frequently reported in sports. The aims for this master thesis were; (1) to examine the prevalence of sport injuries and illnesses among elite sport students at high school with regard to sport group and (2) to examine anthropometry, bone health, performance variables, energy availability and sleep time with associations to sport injuries and illness prevalence in the same sample. Methods Thirty-six high school elite sport students, endurance athletes (n=24) and ball game athletes (n=12) [age: 16.3±0.2 year…
