The impact of sugar and fat reduction on perception and liking of biscuits
2014
Abstract Reducing the fat and/or sugar content in biscuits can be a way to improve their nutritional composition. Seventy-nine consumers of biscuits were recruited to study the impact of these reductions on liking and perception. Four categories of products were selected from a wide range of biscuits available at the French market. Three to six variants of each type of biscuit were produced based on reduced content of sugar, fat or both. Consumers tested the samples under laboratory conditions (6 sessions), recording their liking during initial sessions and crispiness, sweetness and fat perception during latter sessions. Sugar-reduced biscuits were perceived as less sweet than standard bisc…
Combined effect of nutrient and flashing light frequency for a biochemical composition shift in Nannochloropsis gaditana grown in a quasi-isoactinic …
2020
Artificial lighting may be an interesting opportunity for the cultivation of microalgae as an alternative to natural sunlight. In particular, light emitting diodes (LEDs) can be employed to tailor the lighting to the microalgal culture in a controlled mode in order to create flashing light. In order to establish the effect of the flashing frequency on growth and biochemical composition of a model microalga, a quasi-isoactinic reactor, in which the light distribution is almost homogeneous, was set up. In this work, it was employed for the cultivation of the heterokont Nannochloropsis gaditana in two growth media with limiting and nonlimiting nutrients. The combined effect of nutrient concent…
Extracellular Vesicles as Biological Shuttles for Targeted Therapies.
2019
The development of effective nanosystems for drug delivery represents a key challenge for the improvement of most current anticancer therapies. Recent progress in the understanding of structure and function of extracellular vesicles (EVs)—specialized membrane-bound nanocarriers for intercellular communication—suggests that they might also serve as optimal delivery systems of therapeutics. In addition to carrying proteins, lipids, DNA and different forms of RNAs, EVs can be engineered to deliver specific bioactive molecules to target cells. Exploitation of their molecular composition and physical properties, together with improvement in bio-techniques to modify their content are critical iss…

Sneaking into a Hotspot of Biodiversity: Coverage and Integrity of a Rhodolith Bed in the Strait of Sicily (Central Mediterranean Sea)
2022
Habitat mapping, physical characteristics and benthic community of a rhodolith bed in the Pelagie Islands (Strait of Sicily, Mediterranean Sea) were studied through Multi–Beam Echo–Sounder (MBES), Remotely Operated Vehicle (ROV) and grab samples. The geomorphological analysis revealed an articulated and wide rhodolith bed; video inspections highlighted a bed with high coverage, few sandy patches and with a prevalence of the boxwork morphotype. A total of 207 taxa with 876 specimens were identified, and Polychaeta was the dominant taxon. Linguimaera caesaris, a Lessepsian benthic amphipod, was recorded in all sampling sites, and its presence represents an input to deepen the benthic assembla…
Magnetic Field Control of Combustion Dynamics
2016
Abstract Experimental studies and mathematical modelling of the effects of magnetic field on combustion dynamics at thermo-chemical conversion of biomass are carried out with the aim of providing control of the processes developing in the reaction zone of swirling flame. The joint research of the magnetic field effect on the combustion dynamics includes the estimation of this effect on the formation of the swirling flame dynamics, flame temperature and composition, providing analysis of the magnetic field effects on the flame characteristics. The results of experiments have shown that the magnetic field exerts the influence on the flow velocity components by enhancing a swirl motion in the …
Materiali compositi, tecnologie e tecniche costruttive
2011
La definizione di materiale composito è quella di un materiale solitamente non presente in natura che nasce dalla combinazione di almeno due materiali tra loro chimicamente differenti e che presentano un'interfaccia di separazione. I materiali compositi sono utilizzati in strutture, come ad esempio quelle impiegate nel settore aeronautico, per la loro rigidità e leggerezza, nonché per la resistenza alla fatica, alla corrosione e all'impatto. I materiali compositi si distinguono dai metalli perché sono il risultato della combinazione di materiali che differiscono per composizione o forma. Il cemento armato è un eccellente esempio di una struttura composita che consente al calcestruzzo e all'…
Sustainable virtual teams: promoting well-being through affect management training and openness to experience configurations
2021
A disruptive digitalization recently occurred that led to the fast adoption of virtual teams. However, membership diversity and team virtuality threaten members’ well-being, especially if faultlines appear (i.e., subgroups). Considering the job demands–resources model and the role of group affect in shaping members’ perceptions of well-being, we test the effectiveness of a short-term affect management training for increasing members’ eudaimonic well-being. Moreover, based on the trait activation theory and the contingent configuration approach, we draw on the personality composition literature to test how different openness to experience configurations of team level and diversity together m…
Music in school teaching processes through the centuries
2015
Acquisition of music terms is a significant component in a contemporary music lesson in a comprehensive school nowadays. Methodology of teaching music as a separate branch in Latvia started developing in the beginning of the 20th century with the analysis of music educators’ experience published by I. Palevics. However, music as a subject at school has a longer history therefore it would be important to explore the pedagogic role of music in different periods because during music lessons not only students’ musicality and personal development are facilitated but also the tradition of singing which includes the tradition of Song Festival is maintained. In 2008 the tradition of Baltic Song and…
