Productive Efficiency of Decanters with Short and Variable Dynamic Pressure Cones
2003
Abstract This paper presents the results of experimental trials carried out on third-generation, variable dynamic pressure cone decanters to assess machine performance and adjust the process parameters for optimum extraction yield. The results obtained led to the following conclusions: the regulation of the differential velocity screw/bowl allows a better performance of the decanter at low dilutions of the olive paste; it is possible to obtain high efficiency at a low dilution of the olive paste achieving a higher minor compounds content and the more advanced system of regulation leads to better results according to the variations of the ratio between liquid and solid phases, thus optimisin…
Children's Voices and their Impact-Case Study in Romania
2013
Abstract This research evaluates if the voices of children in Romanian preschools are heard and proposes new educational policy in order to train practitioners for preschools. The purpose of the study is to involve practitioners and parents in the Early Years in an experimental training program called: “Voices of children in Romania”. We discovered that according to the traditional attitudes of Romanian parents and practitioners, children's voices are rarely taken into consideration. After the new training program was put into practice in preschools and homes, teachers and parents started to give more attention to children's voices and children's wellbeing was improved.
Challenges and Transformations in Teachers’ Training
2014
Abstract Teacher training scenario today is a cause for serious concern. This research evaluates if the voices of children in Romanian preschools are heard and proposes new educational policy in order to train practitioners for preschools. The purpose of the study is to involve practitioners and parents in the Early Years in an experimental training program called: “Voices of children in Romania”. We discovered that according to the traditional attitudes of Romanian parents and practitioners, children's voices are rarely taken into consideration. After the new training program was put into practice in preschools and homes, teachers and parents started to give more attention to children's vo…
Binds of Professionalism: Attachment in Australian and Finnish Early Years Policy
2016
Attachment theory is often referenced in psychology, social work and early childhood care and education, and is ubiquitous in popular publications directed to parents, carers and educators of young children. It is considered as a ‘grand theory’ that explains “the growth of social relationships from infants’ experiences with their caregivers and the consequent social preference called attachment” (Mercer, 2011, p. 26). In this chapter, we understand attachment theory as a discourse and as part of the ‘psy-complex’, “the sprawling speculative and regulative network of theories and practices that constitute psychology” (Parker, 2002, p. 199). We focus on the operation of ‘attachment discourses…

Prose fiction in the English classoom : perceptions of IB students
2013
Kirjallisuuden opiskelun merkitystä kielenoppimisessa on tutkittu laajalti, ja se on todettu tärkeäksi ja toimivaksi menetelmäksi. Opiskelijoiden omat näkemykset asiasta saattavat myös vaikuttaa oppimistuloksiin, mutta ne ovat aikaisemmassa tutkimuksessa jääneet huomiotta. Tutkielman tarkoituksena on selvittää, pitävätkö oppilaat kirjallisuuden opiskelua hyvänä tapana oppia englannin kieltä. Tutkimus kohdentuu kansainvälisen IB-tutkinnon opiskelijoihin, koska siinä vieraan kielen laajan tason (higher level) opetussuunnitelmaan kuuluu oleellisena osana kirjallisuusanalyysi. Tutkielmassa kartoitetaan laajan tason ja suppeamman tason (standard level) opiskelijoiden näkemyksiä kirjallisuuden kä…

Multifacial Recognition in Binary and Ternary Cocrystals from 5-Halouracil and Aminoazine Derivatives
2018
A systematic analysis using single crystal X-ray diffraction was performed to explore the role exerted by potential intercomponent proton-transfer reactions in the supramolecular structures of A–B cocrystals formed by 5-haloderivatives of uracil (A), coupled with 2-aminoadenine simulants (aminoazines, B). Twelve new heterodimers were synthesized in different stoichiometries and cocrystallized by solvent cogrinding followed by solution crystallization. In the binary cocrystals, uracil or 1-methyluracil with halide modification at the 5 position (F, Cl, Br, I) was coupled with amino-aromatic N-heterocycles (melamine, 2,4,6-triaminopyrimidine, 2,6-diaminopyridine) as a multivalent site for pyr…
Measurements of Low-Energy Protons using a Silicon Detector for Application to SEE Testing
2021
A silicon detector with a fast electronics chain is used for the dosimetry of protons in the range 0.5-5 MeV at the Centro Nacional de Aceleradores (CNA) 3 MV Tandem laboratory in Seville, Spain. In this configuration, measurements can be performed in pulsed mode, using a digitizer to record event-by-event proton energy depositions. The distributions of deposited energy were obtained thanks to a calibration with an alpha source. Measurements of flux and deposited energy are used to enable single event effect (SEE) testing on selected static random access memories (SRAMs).
