No full textArtificial phosphodiesterases that combine a guanidinium unit with a general base connected by a m-xylylene linker catalyze the transesterification of the RNA model compound 2-hydroxypropyl p-nitrophenyl phosphate (HPNP). The bifunctional catalysts presented in this work show varying extents of cooperation between catalytic units and a rate enhancement of 4 x 10(4) in the most favorable case

No full textThe research has focused on aspects that have a direct impact on Indoor Environmental Quality, that are linked with the concept of comfort and are related to different aspects of human behavior in everyday life’s contexts. The research question is “Is it possible to create the right comfort, minimizing the user's activity when he/she is searching for it?” We focused on temperature and, in this regard, we built a checklist that can help collecting data about the different reactions a user has when feeling uncomfortable with the indoor environment around him/her. We collected n.280 checklists in various indoor environments until now. In view of Ambient Assisted Living, we contacted n.5 health-care structures. We are doing observations through the checklist, to collect data about reactions on temperature, light, etc. and we are conducting interviews with professional experts. We collected n.58 checklists and n.21 interviews until now. The research is still underway

Full text linkThe analysis of human behavior in everyday-life situations starts from the assumption that people who act on indoor devices
too often are not entirely conscious of the functioning of these systems and cannot achieve well-being as intended, with nonnegligible
physical and cognitive efforts in weaker subjects. Is it possible to create the best comfort possible in an indoor
environment with minimized activity by final users at any time? This study aims at understanding vulnerable human beings
and their development through the lifespan, detecting their actions in order to design a smart indoor device able to provide
seniors with the ideal comfort level, that cannot be achieved autonomously inside private and institutional environments. Five
healthcare centers located in Italy took part in this project between 2016 and 2017 and a total of 75 field observations have
been carried out in order to gather information about behaviors of people that live in. Findings highlighted that both men
and women seem to act, physically react, and voice their discomfort more in relation to cold, and women appear extremely
sensitive to the temperature and choose more carefully the right clothes based on indoor and outdoor temperatures. A huge
gap seems to exist between the perceptions of senior people and those of their caregivers. This suggests that technological
innovations should improve the quality of life of human beings through a process of customization to target response, especially
in relation to vulnerable categories, and place themselves within an evolutionary framework all along the course of life
Guanidine-guanidinium cooperation in bifunctional artificial phosphodiesterases based on diphenylmethane spacers; Gem -dialkyl effect on catalytic efficiency
No full textDiphenylmethane derivatives 1-3, decorated with two guanidine units, are effective catalysts of HPNP transesterification. Substitution of the methylene group of the parent diphenylmethane spacer with cyclohexylidene and adamantylidene moieties enhances catalytic efficency, with gem-dialkyl effect accelerations of 4.5 and 9.1, respectively. Activation parameters and DFT calculations of the rotational barriers around the C-Ar bonds indicate that a major contribution to the driving force for enhanced catalysis is entropic in nature
