Short-time non-work-related computing and creative performance
2014
It has been argued that non-work-related computing (NWRC) takes time away from work and, hence, decreases work productivity. On the other hand, it has also been claimed that short-time non-work-related computing (STNWRC) (a maximum of 15 minutes), has a positive impact on work productivity, including relief from boredom, higher creativity, and the underlying recovery mechanisms. To examine the impact of STNWRC on creative performance, we draw on Fredrickson's broaden-and-build theory, the concept of recovery with mental well-being and low cognitive effort. A 2 × 2 factorial experiment with 40 subjects was conducted. The results indicate that STNWRC has a positive effect on creative performa…
Influence of aroma compounds on the mechanical properties of pectin gels.
2004
A detailed study of the rheological behavior of pectin gels, in the presence of aroma compounds in food concentration is reported. In high methoxylated pectin (HMP) gels, it has not yet been shown if aroma compounds can be responsible for modifications in rheology. Two rheological techniques were used to measure the impact of aroma substances on rheological properties of HMP-based systems. Maximum strain to fracture (sigma F) was compared between flavored and unflavored gels on stress-displacement curve, which was obtained with uniaxial compression until fracture. An oscillatory rheometer was applied to determine the gelation time (Tgel). It appeared that all the aroma compounds studied inc…
Water-stable cellulose fiber foam with antimicrobial properties for bio based low-density materials
2018
New bio-based packaging materials are highly interesting for replacing conventional fossil based products for a more sustainable society. Waterstable cellulose fiber foams have been produced in a simple one-batch foam-forming process with drying under ambient conditions. The cellulose fiber foams have a low density (33–66 kg/m3) and can inhibit microbial growth; two highly valuable features for insulating packaging materials, especially in combination with stability in water. Cationic chitosan and/or polyvinylamine have been added during the foamforming process to give the foams water-stability and antimicrobial properties. The structural and mechanical properties of the cellulose fiber foa…
Evolución de virus en huéspedes con susceptibilidad variable: consecuencias en eficacia y virulencia
2020
Los virus de RNA se encuentran entre los patógenos emergentes más abundantes. Durante su ciclo de vida normal, los virus se mueven de un huésped a otro, a veces transmitidos por el aire o el agua, pero a veces utilizando vectores en los que también pueden replicarse. Dentro de un huésped individual, los virus se enfrentan a múltiples tejidos y tipos de células que difieren en propiedades fisiológicas y bioquímicas y son constantemente desafiados por una variedad de respuestas inmunes antivirales. Para maximizar su fitness, los virus deben adaptarse necesariamente a todos estos factores. En la mayoría de los casos, esta adaptación se produce fácilmente debido a su enorme potencial evolutivo.…

Values and subjective well-being
2018
Research on relations of personal values to subjective well-being has begun to flourish only recently. This is surprising because our values represent what we consider important and worth pursuing in life, and our subjective well-being (henceforth SWB) represents how happy and satisfied we are with the life we are leading. This chapter summarizes what we know about value—SWB relations and identifies some of what we do not know but would like to know. We first discuss the nature of values and the structured system they form. We then note three theoretical perspectives on relations of values to SWB (Sagiv & Schwartz, 2000; Sagiv, Roccas & Hazan, 2004). The first perspective seeks to explain d…
