    Notes: Abstract The capacitance and voltage characteristics of field effect transistors passivated by BaF2-B2O3-GeO2-SiO2 glasses with various water contents were investigated. As the OH absorption coefficients of the glass increased, adverse effects on the recovery of hysteresisC-V curve shifts was seen. The water content is related to the fluoride content of the BaF2−B2O3−GeO2−SiO2 glass. The viscous flow point of the glass was lowered with increasing ionic character obtained from Hannay's equation. The source-drain current and voltage (I-V) characteristics of typical enhancement and depletion mode field effect transistors passivated with these glasses were investigated.

    Notes: Abstract The capacitance and voltage (C-V) characteristics of Metal-Oxide-silicon (MOS) capacitors passivated by CaF2B2O3-GeO2-SiO2 glasses with OH− ions, water and fluoride contents were investigated. As the OH− absorption coefficients of the glass increased, adverse effects on the recovery of hysteresis C-V curve shifts was observed. The content of OH− ions is closely related to the fluoride content in the CaF2 B2O3-GeO2-SiO2 glass. The viscous-flow point of the glass was lowered with increasing degree of ionic character obtained from Hannay's equation.

    A computed tomography study of Alzheimer's disease by regional volumetric and parenchymal density measurements (1986)

    Notes: Summary Seventeen patients with clinically diagnosed Alzheimer's disease and 13 healthy age-matched controls were studied by means of computed tomography (CT). To assess cerebral atrophy, regional volumetric measurements and parenchymal density measurements were performed. The results indicate that: (1) Alzheimer patients show diffuse cerebral atrophy in the early stage; (2) the evaluation of lobar atrophy by means of CT is useful for the clinical diagnosis of Alzheimer's disease; (3) the evaluation of parenchymal density by means of CT is not as sensitive as the evaluation of lobar atrophy.

    Description / Table of Contents: Zusammenfassung Die vorliegende Studie beruht auf vergleichende CT-Verlaufsuntersuchungen über die Entwicklung hirnatrophischer Vorgänge bei 18 Patienten mit klinisch diagnostizierter Alzheimerscher Krankheit und einer Kontrollgruppe von 14 altersentsprechenden Gesunden. Mit computerisierter planimetrischer Methode in 3 Ebenen wurden der Subarachnoidal-Volumen-Index (SVI) und der Ventrikel-Volumen-Index (VVI) als Parameter für das Ausmaß der korticalen Atrophien bzw. der ventrikulären Dilatationen errechnet. Aus den Ergebnissen lassen sich folgende Schlüsse ziehen: 1. Die cerebrale Atrophie beim Alzheimer-Patienten könnte eher vom Krankheitsprozeß abhängig sein als von physiologischen Altersvorgängen des Gehirnes. 2. Der Grad der Atrophien nimmt mit fortschreitenden klinischen Stadien zu. Dabei sind die korticalen Atrophien bereits in frühen Stadien erkennbar, während die Ventrikelerweiterungen erst in späteren erscheinen. 3. CT könnte einer der nützlichsten klinischen Tests für die Diagnostik der Alzheimerschen Krankheit sein.
    Notes: Summary Computed tomography (CT) was used to study cerebral atrophy in 18 patients with clinically diagnosed Alzheimer's disease of presenile type and in 14 healthy age-matched subjects as controls. Using the computerized planimetric method, Subarachnoid Space Volume Index and Ventricle Volume Index were calculated as the measure of cortical atrophy and ventricular dilatation respectively. From the results the following conclusions were drawn: 1. The cerebral atrophy in Alzheimer patients could be attributable to the disease processes rather than to physiological aging of the brain. 2. The degree of atrophy increases in parallel with the progress of the clinical stage, and the cortical atrophy is already apparent at an early stage, whereas the ventricular dilatation becomes pronounced at later stages. 3. CT could be one of the most useful clinical tests available for the diagnosis of Alzheimer's disease.
