An analytical model of the pressure and temperature sensitivity of a permanently installed downhole monitoring sensor is presented. The sensing concept is embodied in a micromachined silicon resonator using optical excitation and interrogation. The relation between pressure and resonant frequency is

✦ Synopsis
The present work describes the design and manufacture of a prototype (currently in use) of an intelligent sensor for the tracking and monitoring of blood temperature and of hemoderivatives to be used in transfusions, over the entire process. Furthermore, this system provides information in real time of the blood reserves organized according to their characteristics (Rh, type, date, etc.). The device is based on RFID (Radio Frequency IDentification), this being the method that best suits the needs of these types of health materials. The system helps track the blood in space and time from extraction to transfusion. In this way, the blood is monitored according to certain parameters: the time elapsed and the temperature that could determine its state before transfusion. The system has been tested in hospitals and the results have been excellent.

Thrombin is central to the process of coagulation and monitoring its activity is a reliable indicator of the rate and extent of coagulation. I have employed a range of fluorogenic peptide substrates as indicators of coagulation via the formation of active thrombin. This system enabled coagulation to
## Abstract **Summary:** A drop‐on‐demand ink‐jet printer has been used to print a silver‐organic solution onto glass substrates. Conductive silver tracks were obtained by heat treatment of the ink‐jet printed deposits at temperatures ranging from 125 °C–200 °C in air. Resistivity values were found
An advanced palladium/platinum resistance sensor has been developed to measure, in situ, dissolved hydrogen in high temperature aqueous systems. The measurement of hydrogen is based on the wellknown fact that the resistance of palladium changes with the absorption of hydrogen into the lattice. Compa
Gas temperature and water concentration are measured by a tunable diode laser sensor using a single laser near 1.4 m. Temperature is determined from the ratio of absorption of a H 2 O line pair near 7079.176 and 7079.855 cm -1 , which are chosen using some selected criteria. The second harmonic dete
