    Notes: Abstract The results of investigations of the chemical and electrochemical polymerization of aniline in sulphamic acid medium and its characterization by electrochemical and spectroscopic techniques are presented. The investigations reveal that sulphamic acid medium affects, not only the polymerization process, but also its electrochemical characteristics.

    Notes: Abstract Polyaniline exists in various forms distinguished by the number of protons bonded to nitrogen, which determines the degree of oxidation of the polymer. At a macroscopic scale, doping involves electron transfer as well as protonation of the nitrogen heteroatom, which stabilises localised bound states to impart electronic conductivity to the system. However, it has been observed that the processability of this intractable polymer is greatly influenced by the anion associated with the protonating agent. Here we briefly summarise the influence of the anion on the behaviour of polyaniline.

    Description / Table of Contents: Zusammenfassung Diese Studie wurde zur Bestimmung der Inzidenz der koronaren Herzkrankheiten und des Bluthochdruckes sowie der assoziierten Risikofaktoren in der Bevölkerung des Kheda Distriktes, Gujarat, unternommen. Die vorliegende Arbeit stellt die Resultate aus den ersten fünf Jahren dieses immer noch laufenden Projektes vor. 714 Personen im Alter von 30–62 Jahren wurden studiert. Alle einbezogenen Probanden wurden klinisch und labormässig untersucht. Eine detaillierte sozio-ökonomische Anamnese wurde erhoben. In der Folge unterlagen alle Teilnehmer zweimal jährlich einer klinischen und einer labormässigen Untersuchung. Die Fälle von KHK wurden gemäss der Empfehlungen der New York Heart Association diagnostiziert. Die 5-Jahres Inzidenz der KHK lag bei 25, 17‰. Die Inzidenz bei den Männern war dreimal höher als diejenige der Frauen. Während die Männer vermehrt unter Herzinfarkten litten, kamen bei den Frauen plötzliche Todesfälle häufiger vor. Es bestand eine signifikante Assoziation zu erhöhten Blutdruckwerten, zum Rauchen, zu einer Familienanamnese für Herzkrankheiten und eine schwache Assoziation zum Körpergewicht.
    Abstract: Résumé Une étude a été conduite dans le district Kheda (Gujarat, Inde), pour mesurer l'incidence de la maladie coronarienne, de l'hypertension artérielle et de leurs facteurs de risque. Les résultats des 5 premières années de l'étude, sont présentés ici. Un échantillon de 714 personnes de 30 à 62 ans a été selectionné par un échantillonnage aléatoire de la population à partir des listes électorales. L'échantillon étudié ont été soumises à un premier examen clinique complet, et à un interrogatoire socio-démographique. L'examen clinique sont répétés deux fois par an chez tous les sujets. Les MCV ont été diagnostiqués selon les critères de la New York Heart Association. Sur les cinq ans d'observation, l'incidence des MCV est de 25, 17 pour mille personnes, avec une incidence trois fois plus élevée chez les hommes que chez les femmes. L'incidence de l'infarctus du myocarde est plus importante chez les hommes alors que la mort subite est plus fréquente chez les femmes. La survenue d'une MCV est associée de façon significative avec une augmentation de la tension artérielle, avec le fait d'être fumeur, avec des antécédents familiaux de MCV et avec la masse corporelle ou le poids.
    Notes: Summary The present study was undertaken to determine the incidence and related risk factors for coronary heart diseases and hypertension in the rural population of Kheda district, Gujarat (India). The observations from the first five years of this ongoing project (May 1987–May 1992) are described in this paper. Out of an initial sample of 750 individuals in the age group 30–62 years, who were selected by stratified random sampling, 714 persons (males=429; females=285) were actually studied, after excluding those suffering from coronary heart diseases (CHD). Initially, all the included subjects were examined clinically and appropriate laboratory investigations were done. A detailed socioeconomic history was also obtained. Subsequently all of them were followed up and biannual clinical and laboratory investigations were performed. Cases of CHD were diagnosed according to the recommendations of the New York Heart Association. The overall five-year incidence of CHD was 25.17 per thousand persons. The incidence in males was 3 times higher than in females. More males suffered from myocardial infarction (MI), while in the females the incidence of sudden death was higher (33.3%). The average yearly mortality rate due to CHD was 2.46 per thousand persons. CHD was significantly associated with increased blood pressure (both diastolic and systolic), smoking, and family history of heart disease, and was weakly associated with body weight (p=0.06).

    Notes: The effect of a simulated marine environment on unstabilized polyethylene-polyethylene oxide blends, having varying polyethylene oxide content (up to 40% by weight), with or without a metal catalyst (e.g., cobalt (III) acetylacetonate) and a metal containing plasticizer (e.g., aluminum stearate), has been studied for 10 weeks exposure time. In the absence of metal catalyst and plasticizer, phase separation of polyethylene oxide was quite evident visually after melt mixing and subsequent regular compression molding of polyethylene-polyethylene oxide blends. However, these blends rendered better and uniform mixing in the presence of metal catalyst and plasticizer. Since polyethylene oxide is a water soluble component of the system, % weight loss increased significantly with increase in its content after exposure to brine. These blends have been further characterized by tensile properties, optical and scanning electron microscopy, and thermal analysis in order to monitor mechanical as well as morphological changes.

    Notes: The synergic effect of the substituentlike ethoxy group on the electronic properties of conducting polyaniline was investigated. The presence of substituents affects not only the electrochemical polymerization window but also brings about changes in optical and electronic properties of the parent polymer polyaniline. The study indicates that electrochemical polymerization of (o-ethoxyaniline) yields a conducting polymer that shows a multiple color transition (yellow → green) on switching the potential between the reduced and oxidized states with an electrochromic response time of 40 ms in addition to its solubility in dimethyl sulfoxide, N-methyl pyrrolidinone, etc. However, the chemical polymerization of the monomer yields a crimson red polymer that is less conducting but has solubility in ethanol/methanol. Evaluation of this alcohol soluble polymer as a corrosion inhibitor for iron in acidic medium shows that it offers corrosion inhibition efficiency of 90%. © 1995 John Wiley & Sons, Inc.

    Notes: To establish the parameters for converting sheet molding compounds (SMCs) to useful products, various technical approaches, viz., solvent extraction, hydrolysis, and pyrolysis, have been explored. Thermogravimetric analysis of an SMC sample indicated that it contains about 25% by weight organics and 75% inorganics, mainly glass fibers and CaCO3 as filler. Solvent extraction of ground SMC with acetone, methylene chloride, chloroform, or chloroform : benzene (1 : 1 vol) yielded low quantities of a gummy, viscous extract. Hydrolysis of the extracted SMC sample under strong alkaline conditions was also studied. A unit structure was postulated for the hydrolysate based upon elemental and molecular weight analysis. Pyrolysis of both extracted and unextracted SMCs in nitrogen at 500°C and in air at 400°C yielded organic oils. These oils were characterized for their calorific values. The products of pyrolysis consisted of mainly aromatics along with some oligomers. The extract and the oil from pyrolysis appear to be compatible with epoxy systems. Their use as an extender for epoxy systems, while that of the inorganic residue (glass fibers and CaCO3) as a filler for epoxy system, have been explored. © 1993 John Wiley & Sons, Inc.
