Points to be considered in thermogravimetry

Continuous thermogravimetry is a common method to test materials in gaseous corrosive environments at high temperatures and to elucidate kinetics and mechanisms of high temperature corrosion. Recommendations how to conduct thermogravimetric tests are collected here, points to be considered including sample size and form, surface preparation, reaction chamber, starting procedure, sensitive measurements, gas supply and dosing. This study is meant as a starting foundation for establishing guidelines in high temperature corrosion research.     

A fuzzy derivative approach to classification of outcomes from the ADRAC database

The Australian Adverse Drug Reaction Advisory Committee (ADRAC) database has been collected and maintained by the Therapeutic Goods Administration. In this paper we study a part of his database (Card2) which contains records having just reactions from the Cardiovascular group. Drug‐reaction relationships are presented by a vector of degrees which shows the degree of association of a drug with each class of reactions. In this work we examine these relationships in the classification of reaction outcomes. A modified version of the fuzzy derivative method (FDM2) is used for classification.     

Nuclear antiferromagnetic exchange in two dimensional solid3He

Measurements are reported of the magnetic susceptibility of pure³He films, at coverages for which the nuclear exchange interaction is antiferromagnetic. A comparison is made with earlier results obtained on preplated graphite. The data suggest that all the spins participate in the exchange.     

Comparison of mathematical programming software: A case study using discrete L1 approximation codes

This paper presents the methodology and results of a computational experiment which compares the performance of four computer codes which determine the best discrete L₁ approximation to a continuous nonlinear function. The experiment utilizes 320 test problems created by a test problem generator. Several performance measures describe solution quality as well as computational effort.     

Prediction and measurement of core losses in a high-speed switched-reluctance Machine

We describe a procedure for calculating the core loss in high-speed switched-reluctance machines. The technique calculates core losses within a switched-reluctance machine to a high degree of spatial resolution over a wide range of operating conditions. We confirmed the calculations experimentally, using a loss segregation method, and found good correlation.     

Apolipoprotein E genotypes in a neuropathological series from the Consortium to Establish a Registry for Alzheimer''s Disease

A new classification system, termed complex regional pain syndromes types I and II, has been devised to replace the nomenclature of pain disorders previously termed reflex sympathetic dystrophy and causalgia. CRPS type I does not have identifiable major nerve injury, whereas CRPS type II has an identifiable major nerve injury. The classification is based on clinical symptoms and signs without incorporating any mechanistic connotations. These CRPS disorders may have SMP, SIP, or both.
