This paper reports on the detection of nano-scale chemical variations in photosensitive polymers using scanning thermal probes fabricated from polyimide and metal thin films on a silicon substrate. The high thermal insulation achieved by these probes permits the measurement of thermal conductance variations <10 W/K. The probes are mechanically very compliant, with a typical a measured spring co...

Background: Thermal waters have been showing different beneficial effects on the skin due to their physicochemical composition. The effect of thermal water in treatment some diseases may thus justify its use as an active ingredient cosmetic formulations. main objective this work was demonstrate potential incorporating (2) Methods: A descriptive literature review carried out by analysis scientif...

Future middleware platforms will need to be more configurable in order to meet the demands of a wide variety of application domains. Furthermore, we believe that such platforms will also need to be reconfigurable, for example to enable systems to adapt to changes in the underlying systems infrastructure. A number of technologies are emerging to support this level of configurability and re-confi...

The primary nonbiological result of recent rapid climate change is warming winter temperatures, particularly at northern latitudes, leading to longer growing seasons and new seasonal exigencies and opportunities. Biological responses reflect selection due to the earlier arrival of spring, the later arrival of fall, or the increasing length of the growing season. Animals from rotifers to rodents...

The extension of ecological tolerance limits may be an important mechanism by which microorganisms adapt to novel environments, but it may come at the evolutionary cost of reduced performance under ancestral conditions. We combined a comparative physiological approach with phylogenetic analyses to study the evolution of thermotolerance in hot spring cyanobacteria of the genus Synechococcus. Amo...

We present a model for a thermal Brownian motor based on Feynman’s famous ratchet and pawl device. Its main feature is that the ratchet and the pawl are in different thermal baths and connected by an harmonic spring. We simulate its dynamics, explore its main features and also derive an approximate analytical solution for the mean velocity as a function of the external torque applied and the te...

1 The medical staff might not have to be represented here since they only enter what factors that should be monitored and so they can be seen as the same entity as the nurses' station.
