Evidenze sulla razionale somministrazione di Levodopa

Introduzione Ad oltre 40 anni dalla sua introduzione [1] la levodopa (LD) rimane il farmaco più importante ed efficace nel trattamento della malattia di Parkinson (MP). La LD, infatti, ha rivoluzionato la terapia sintomatica della MP riducendo l’entità dei disturbi motori, migliorando l’autonomia e la qualità di vita dei pazienti ed incrementandone l’aspettativa di vita. Nessun altro trattament...

Bias-dependent Peltier Coefficient in Bipolar Devices

Temperature stabilization is important in many microelectronic devices due to thermal constraints on device operation and lifetime. The work described here is an investigation of thermoelectric phenomena in bipolar devices, speci£cally the p-n diode. Current injection can modify the Peltier coef£cient at interfaces; this can give rise to thermoelectric cooling or heating depending on device par...

Peltier cooling in molecular junctions.

The study of thermoelectricity in molecular junctions is of fundamental interest for the development of various technologies including cooling (refrigeration) and heat-to-electricity conversion 1-4 . Recent experimental progress in probing the thermopower (Seebeck effect) of molecular junctions 5-9 has enabled studies of the relationship between thermoelectricity and molecular structure 10,11 ....

Nonlinear Peltier Effect in Quantum Point Contacts

A theoretical analysis of the Peltier effect in two-dimensional quantum point contacts, in field-free conditions and under the influence of applied magnetic fields, is presented. It is shown that in the nonlinear regime (finite applied voltage) new peaks in the Peltier coefficient appear leading to violation of Onsager’s relation. Oscillations of the Peltier coefficient in a magnetic field are ...
