Experimental design approach in the synthesis of molecularly imprinted polymers specific for iprodione fungicide
2015
International audience; An experimental design (ED) approach was applied to study the weight of three factors in the synthesis of a molecularly imprinted polymer (MIP) specific for iprodione fungicide. The objective was to obtain a high specific polymer with the best performance of iprodione binding. Thirteen iprodione-imprinted polymers and 13 non-imprinted polymers (NIP) were synthesized according to ED having 3 influencing factors: the polymerization method, the crosslinker nature and the functional monomer type. For each factor, two levels were studied: bulk and precipitation polymerization for the first factor, trimethylolpropane trimethacrylate (TRIM) and ethylene glycol dimethacrylat…
Is clinical experience important for obtaining the primary stability of dental implants with aggressive threads? An ex vivo study
2018
GECKILI, ONUR/0000-0002-7852-3915; dayan, suleyman cagatay/0000-0003-3081-9618; Bilhan, Hakan/0000-0003-1787-3003 WOS:000460131200015 PubMed ID: 30818319 Background: The aim of this study was to investigate the clinicians' experience on maintaining the primary stability of implants with aggressive threads belonging to a novel dental implant system. Material and Methods: Three hundred implants with aggressive threads were inserted in fresh bovine ribs mimicking Type IV bone by five clinicians which were classified according to their previous experience of total number of implant insertion. An independent examiner measured the primary stability of all implants after insertion by using resonan…
Flavour release at the interfaces of stirred fruit yoghurt models
2006
Abstract Model matrices consisting of a pectin and a dairy gel were investigated to study the transfer of flavour compounds between the different phases of stirred fruit yoghurt. Using a full factorial experimental design, different parameters (storage temperature, initial flavour concentration in the pectin gel and fat content of the dairy gel) were studied. The kinetics of the migration of flavour compounds between the two gels were investigated using a novel SPME method, where a Carboxen/Polydimethylsiloxane fibre was directly inserted into the pectin gel. Flavour compounds were predominantly retained in the pectin gel and thus, the presence of fat in the dairy gel did not affect their t…
Check in, check out! : käyttäytymisen tehostettua tukea lähikoulussa
2018
Finnish schools struggle with problem behaviour and need new interventions which are effective, acceptable, and can be implemented with high fidelity in general classrooms. The aim of this study was to examine the effects of Check in check out (CICO) support in decreasing the disruptive behaviours of general education primary school pupils. CICO can be regarded as an intensified level of support in Finnish schools, and its key features are brief morning and afternoon meetings with a CICO coach, the use of a Daily Report Card (DRC), regular positive feedback during the day by the classroom teacher, and parental involvement. The specific aims of the study were threefold: first, to pilot the i…
Online and face-to-face role-play simulations in promoting social work students’ argumentative problem-solving
2013
This paper reports on a teaching experiment in which social work students (n=38) practiced problem solving through argumentative tasks. A teaching experiment was carried out at a Mikkeli University of Applied Sciences in Finland in connection with a course concerning preventative work against alcohol- and drug abuse. This quasiexperimental study investigated whether role-play simulation conducted either online (15 students) or face-to-face (14 students) improved students’ problem solving on social issues. As a pre-test, the students wrote an essay after having watched a dramatization of problematic cases on elderly people’s use of alcohol. The students also attended lectures (30 x 45 min) o…
Self-Distancing as a Strategy to Regulate Affect and Aggressive Behavior in Athletes: An Experimental Approach to Explore Emotion Regulation in the L…
2020
Self-regulation, especially the regulation of emotion, is an important component of athletic performance. In our study, we tested the effect of a self-distancing strategy on athletes’ performance in an aggression-inducing experimental task in the laboratory. To this end, we modified an established paradigm of interpersonal provocation [Taylor Aggression Paradigm (TAP)], which has the potential to complement field studies in order to increase our understanding of effective emotion regulation of athletes in critical situations in competitions. In our experimental setting, we first tested the applicability of the self-distancing perspective and the athletes’ ability to dynamically adapt beside…
Behavioral Activation through Virtual Reality for Depression: A Single Case Experimental Design with Multiple Baselines
2022
Behavioral activation (BA) is a structured psychotherapeutic approach for the treatment of major depressive disorder (MDD), which aims at increasing the engagement in activities that might bring enjoyment and meaning to patients’ lives. Although a growing body of evidence supports the effectiveness of BA, enhancing the motivation and activity level of depressed patients is often challenging. In the present study, we explored the effectiveness of a brief BA treatment supported by virtual reality (VR) to facilitate the visualization and anticipation of four pleasurable activities that we tried to re-introduce in the patients’ daily routine. To do so, we conducted a single-case experimental de…
