TL;DR: The occurrence of occupational contact dermatitis among workers in a rubber factory from 1976 to 1980 was studied and paraphenylenediamine compounds and solvents were the main cause.
Abstract: The occurrence of occupational contact dermatitis among workers in a rubber factory from 1976 to 1980 was studied Insurance compensation was paid to 50 workers with dermatitis 21 of the cases were allergic and 27 toxic contact dermatitis, giving a contact dermatitis frequency of 56/1000 workers Paraphenylenediamine compounds were the main cause of allergic contact dermatitis and solvents the main cause of toxic contact dermatitis

TL;DR: The risk of cancer of the digestive organs, respiratory organs, and urinary bladder was higher than expected, and the risk increased with the length of the follow-up time, however, the differences were not statistically significant.
Abstract: A follow-up study was carried out among workers in the processing and tire and tube fabrication departments of a Finnish rubber plant. A total of 1,331 workers were followed up for cancer through the files of the Finnish Cancer Registry from 1953 to 1976 (11,709 person years). The expected number of cancer cases was calculated on the basis of the age and sex-specific incidence rates for the urban population of the surrounding province. Twenty-one cancer cases were found against 18.9 expected (RR 1.1, 95% confidence interval 0.7–1.7). The risk of cancer of the digestive organs, respiratory organs, and urinary bladder was higher than expected, and the risk increased with the length of the follow-up time. However, the differences were not statistically significant.

TL;DR: In this paper, the authors examined Duane learning curves for reliability improvement between successive reliability tests and found that a constant failure rate ratio between successive tests gives curved lines on a Duane plot.
Abstract: This paper examines Duane learning curves for reliability improvement between successive reliability tests. A constant failure rate ratio between successive tests gives curved lines on a Duane plot. Gordon's observation that dominant failures appear exponentially with test time leads to exponential failure rate ratio models. These models, although not the only possible ones, give results that agree well with observations from practice.

TL;DR: METHODE DE REGLAGE DE LA POSITION DES CATHODES DANS LE CYLINDRE DE WEHNELT D'UN TUBE CATHERODIQUE A FAISCEAUX MULTIPLES, PAR EXEMPLE UNTUBE IMAGE A TROIS CATHODE POUR TELEVISEUR EN COULEUR as discussed by the authors.
Abstract: METHODE DE REGLAGE DE LA POSITION DES CATHODES DANS LE CYLINDRE DE WEHNELT D'UN TUBE CATHODIQUE A FAISCEAUX MULTIPLES, PAR EXEMPLE UN TUBE IMAGE A TROIS CATHODES POUR TELEVISEUR EN COULEUR. LES POSITIONS EXACTES DES BUTEES D'ARRET 9 DE LA PLAQUE DE SUPPORT DES CATHODES 6 ET CELLES DES OUVERTURES 12 DE PASSAGE DES FAISCEAUX A LA BASE DU CYLINDRE DE WEHNELT 1 SONT REPORTEES A L'EXTERIEUR DU TUBE PAR DES GABARITS RESPECTIFS 8 ET 10 GUIDES INDIVIDUELLEMENT DANS UN BLOC DE REGLAGE 11 QUI S'AJUSTE DANS LE CYLINDRE 1 AVANT LE MONTAGE DES CATHODES 3. LE MONTAGE ET LA FIXATION DES CATHODES 3 DANS LEURS MANCHONS RESPECTIFS 4 PRE-ASSEMBLES SUR LE SUPPORT 6 S'EFFECTUE PAR RAPPORT AUX GABARITS 10 TANDIS QUE LE SUPPORT EST MAINTENU CONTRE LES GABARITS 8. L'ENSEMBLE EST RETIRE PAR L'ARRIERE DANS L'AXE DU TUBE ET LE SUPPORT 6 EST ENSUITE POUSSE DANS SA POSITION DEFINITIVE CONTRE LES BUTEES 9.
