    Notes: Abstract Objectives: The aim of this study was to characterize the use of seralbumin, evaluating how appropriate its prescription is and what possible economic repercussions may result from inappropriate use. Methods: We performed a prospective study that included all patients receiving albumin in two University Hospitals from October 1995 to March 1996. The reasons for albumin use were considered appropriate if they coincided with the recommendations of a panel of experts. Results: During the study period, 197 patients received albumin and a total of 3208 50-ml vials (20%) were used. The internal medicine and gastroenterology services prescribed this drug the most often. The most frequent prescription motives were paracentesis in cirrhotic patients (25.9%), hypoalbuminemia (24.9%) and chronic handling of cirrhotic patients (18.6%). Only 16 prescriptions (8.1%) (corresponding to 315 vials, 9.8%) were considered appropriate. One cause of inappropriate prescribing was that colloid solutions had not previously been used in 56 (30.9%) of the 186 inappropriate prescriptions. During the study period, 74 306 ECUs were spent on inappropriate indications. Conclusions: The use of albumin in our centers is incorrect and has important economic repercussions. Some educational and informative measures must be established to change this situation.

    Notes: Abstract Reliability is a critical word in industrial applications of Shape Memory Alloys. Accurate and reproducible transformation hysteresis cycles and internal loops were obtained in single crystals using a high resolution automatized equipment. From a mechanical model formulated for a single martensite plate, the shape of the hysteresis cycle is obtained by generalizing the representation toN plates. The observed time effects on the hysteresis loops related to diffusion processes were also taken into account. It allows to explain the martensite recoverable creep and the micromemory effects. Also, the room temperature effects on the parent phase (for instance, summer to winter) acting over the transformation temperature are quantified.

    Notes: Abstract A non-differential calorimetric analyzer was developed for an INSTRON 1123 machine (a stress-strain-temperature analyzer) with a temperature chamber INSTRON 1110. The study was performed using the Joule effect and pseudoelastic martensitic transformations in single crystals of Cu-Zn-Al alloys. The analysis of the system establishes that: the sensitivity of calorimetric measurements after a filter of two poles and two zeros is 166 mV W-1 (at 297 K), the noise is near 1.5 μV and the drift is close to 30 μV in 6 h. The reproducibility of the sensitivity working with one sample is better than ±0.3%, and the change to a new sample keeps the value below ±0.5%. The uncertainty in reproducibility in the martensitic transformation (including repositioning) does not overcome ±1.6%. The used calorimetric sensors limit the temperature to 373 K. The furnace control originated fluctuations on the base line (near ±20 μV), which by means of an auxiliary signal processing were reduced to 50% (less than ±10 μV).

    Notes: Abstract In this paper we describe the way for an efficient design of velocity-tuned spatiotemporal filters using analogue neural networks. The filter presented here has a simple velocity-matched structure discrete in space but continuous in time yielding to efficient VLSI realisations and it overcomes some drawbacks of previous similar approaches found in the literature. We show how this filter can be used to compute a distributed representation of velocity similar to that obtained with classical spatiotemporal frequency-tuned Gabor filters.
