Calculation of ternary polymer solution phase diagram via compressible lattice fluid model extended to specific interactions
2012
Ternary polymer solutions are currently employed for the production of porous structures (e.g. membranes and scaffolds for tissue engineering) via liquid-liquid phase separation techniques. The relation between processing conditions and thermodynamic features of the considered polymeric system determines the morphology of the as-prepared membrane. Therefore, in order to achieve a better control on a porous structure, a deep characterization of the phase behavior of a polymer solution is needed. The experimental derivation of phase diagrams is highly cost and time consuming, thus usually the cloud point curves of the system are directly measured. In this work, the compressible lattice fluid …
Gas-liquid-solid operation of a Long Draft Tube Self-ingesting Reactor (LDTSR)
2008
Gas-liquid stirred vessels are widely employed to carry out chemical reactions involving a gas reagent and a liquid phase. The usual way for introducing the gas stream into the liquid phase is through suitable distributors placed below the impeller. An interesting alternative is that of using “self ingesting” vessels where the headspace gas phase is injected and dispersed into the vessel through suitable surface vortices. In this work the performance of a Long Draft Tube Self-ingesting Reactor dealing with gas-liquid-solid systems, is investigated. Preliminary experimental results on the effectiveness of this contactor for particle suspension and gas-liquid mass transfer performance in pres…
Mass transfer and hydrodynamic characteristics of a Long Draft Tube Self-ingesting Reactor (LDTSR) for gas-liquid-solid operations

Situational factors shape moral judgements in the trolley dilemma in Eastern, Southern and Western countries in a culturally diverse sample
2022
The study of moral judgements often centres on moral dilemmas in which options consistent with deontological perspectives (that is, emphasizing rules, individual rights and duties) are in conflict with options consistent with utilitarian judgements (that is, following the greater good based on consequences). Greene et al. (2009) showed that psychological and situational factors (for example, the intent of the agent or the presence of physical contact between the agent and the victim) can play an important role in moral dilemma judgements (for example, the trolley problem). Our knowledge is limited concerning both the universality of these effects outside the United States and the impact of …
Family history to type 2 diabetes influence on body parameters of young soccer players
2011
The aim of our study was to analyze the difference of phenotype in healthy soccer players with family history of type 2 diabetes and healthy soccer players without family history of type 2 diabetes. The anthropometric parameters and body composition was analysed. The group with positive family history (FH+) had the highest values of wrist circumference (p<0.05) associated with not statistically significant increase of body fat mass and fat free mass. Also, the heart function was analysed. FH+ players had a diastolic basal pressure values higher than other group, but other functional parameters were the same. Analysing lung function indicators, FH+ players showed significant greater FEV1 and…

The mechanism of retro-cue effect in visual working memory : Cognitive phase separation
2020
Retro-cue effect (RCE) refers to the phenomenon that individuals can use retro-cues to improve their visual working memory (VWM) performance of target items after memory stimuli disappear. To explain the mechanism of RCE in VWM, five different hypotheses have been proposed by previous studies: the hypothesis of enhancing target representations, the hypothesis of forgetting non-target representations, the hypothesis of preventing memory degradation, the hypothesis of preventing interference from probe array and the hypothesis of cognitive phase separation. Although RCE has been repeatedly observed in previous studies, the mechanism of RCE remains unclear. In this study, we conducted three ex…

"I never gave up"
2019
Esports phenomena have grown rapidly in recent years, and so has research on the topic. Some of the research has also addressed esports fandom (see e.g. Taylor 2012). Nevertheless, studies comparing and contrasting how players and fans engage with the game and the esports based on that game are scarce. This study compares and contrasts how players and fans engage with playable game characters and esports players. The paper draws on previous research in fan studies, sports fandom and esports to examine the relationships of players and fans of the videogame Overwatch (Blizzard Entertainment 2016) with the fictional heroes of the game as well as with their favorite professional players in the …
