The use of in-line quantitative analysis to follow polymer processing
2009
In this work it is presented three applications of real time analysis during extrusion process using an optical device developed by our research group, which applies the concepts of light extinction. Monitoring of polymer blends morphology takes place to infer data concerned to dispersed phase size and concentration. The detector also enables information about melting temperature of polymer during extrusion and the level of viscous heating, and the exfoliation step during processing of a polymer-clay nanocomposite.

Reactive Compatibilization of PBT/EVA Blends with an Ethylene-Acrylic Acid Copolymer and a Low Molar Mass Bis-Oxazoline
2004
Polyesters and polyolefins form highly incompatible blends with poor properties and gross morphology that hinder any practical applications. In this work, the possibility to compatibilize an incompatible blend of poly(butylene terephthalate) (PBT) with ethylene vinyl acetate (EVA) by adding a bis-oxazoline compound, 2,2'-(1,3-phenylene)-bis(2-oxazoline) (PBO), and an ethylene acrylic acid copolymer (EAA) as compatibilizer precursors has been studied. The results indicate that the binary uncompatibilized blends show poor mechanical properties and a bad morphology with scarce adhesion between the phases. The situation is only slightly improved when the EAA is added while the best performance …
On the degree of binder activity of reclaimed asphalt and degree of blending with recycling agents
2020
It is common practice to assume full blending of the aged binder of reclaimed asphalt (RA) within the design of new asphalt mixtures. Although being practical, this assumption has often led designers to asphalt mixtures lacking binder. Hence, going towards recycled asphalt mixtures (RAM) there is a need to have a better understanding of the blending phenomena, to have a general agreement on terminology and finally adapting RA classification and mix design procedures accordingly. This manuscript aims at being both a reference and stimulus for the scientific community to work in this direction and on this basis provides a nomenclature and a theoretical framework of the blending phenomena. The…
Sophie Hannah’s Hurting Distance as Crime Trauma Fiction
2020
Rodi-Risberg addresses trauma’s generic border-crossing movement through Sophie Hannah’s socially conscious crime thriller Hurting Distance (2007), a trauma narrative of sexual violence and emotional abuse that can be referred to as crime trauma fiction because it incorporates and blends features of both genres. Rodi-Risberg’s main argument is that crime trauma fiction such as Hannah’s novel represents traumatic experience as politically significant by mobilising affect through its themes of violence as social critique. The chapter concludes that contemporary narratives of crime and trauma such as Hannah’s should be seen as an important locus not only for representing traumatic experience, …
International distance learning design experiences. Above the clouds, a project for a temporary event in the Bolognetta valley
2021
The health emergency due to the spread of COVID-19 has required a methodological and technological adaptation to the entire world of teaching and researching, in order to define in a brief time new methods for designing and teaching. In consideration of this, Campus Asia1 decided to organize one of the key events of its educational offer in a distance learning form, an international winter school with overn eighty participants and five international guest universities. Together with Kyushu University (China), Tongji University (Japan) and Pusan National University (South Korea), the edition held between 15 and 26 February 2021 saw the participation of two European partner universities, the …
Yhteisöllinen argumentointi sosionomikoulutuksessa avoimia ongelmia ratkottaessa
2017
The aim of this study was to develop teaching methods for practising argumentative problem-solving in a degree program of social services. The purpose was to acquire knowledge about multiple (face-to-face, online, and integrated) learning environments for studying argumentative problem-solving. In addition, the typical features of collaborative argumentation in student discussions were identified. Two teaching experiments were arranged in courses on drug and alcohol abuse. Both experiments required students to solve open-ended problems through role-play regarding a fictive girl’s use of alcohol. The idea of blended learning was applied in the first teaching experiment. Students (n = 29) wro…
Using a mobile application to support children's writing motivation
2013
PurposeThe purpose of this paper is to explore the use of the prototype of a mobile application for the enhancement of children's motivation for writing. The results are explored from students' and experts' perspectives.Design/methodology/approachThis study is based on a field trial and expert evaluations of a prototype of a mobile application. The field trial data consists of questionnaire data collected from elementary school students (n=25) who used the mobile prototype. The expert evaluations (n=8) of the prototype were conducted based on usability and pedagogical heuristics. The main research question is how the mobile application motivates children to learn creative writing.FindingsTh…
Co-evolution between Trust in Teachers and Higher Education Enabled by ICT Advancement – A Suggestion to ICT Growing Economies
2016
In light of the increasing significance of trust-based higher education towards digitally-rich learning environments, co-evolution dynamism between trust in teachers and higher education enabled by ICT advancement was analyzed. Using the rate of trust in teachers for good education in the Global Teacher Status Index, together with statistics on higher education level and ICT advancement, an empirical numerical analysis of 20 countries was attempted. It was identified that while ICT advanced countries have constructed a co-evolution between ICT, higher education and trust, ICT growing countries have not succeeded due to a vicious cycle between ICT and trust. Finland’s educational success can…
Flipped Learning Experiment in Video-Based Education
2017
Videos intended for educational use have increased significantly in recent years. This is partly due to the increasing use of videos for entertainment purposes, as well as an increase in broadband connections. Educational videos may include short video clips, screen capture videos or, for example, recordings from the classroom teaching situation. Videos can be utilized in revising, for compensating absences, making teaching more flexible or for developing presentation skills. The recording also enables the re-use of lectures. This allows completely new types of educational solutions, such as the implementation of flipped learning. In flipped learning, activities traditionally carried out in…
