ABSTRACT
The Authors analyse the Italian, technical series called Manuali Hoepli, devoted to promote technical knowledge in the second half of XIXth century. Johann Ulrich (Ulrico) Hoepli (1847-1935) came from Switzerland to Milan in 1870, and translated into Italian some volumes edited by Macmillan in London (from Science Primers series). During his life, he printed 2000 Manuali Hoepli. Some of them were devoted to Occupational Medicine. Five volumes are presented: Magrini's one was devoted to technical devices to prevent industrial accidents; Allevi's Manual was printed when Milan Clinica del Lavoro was preparing; Altarelli and Bortolotto's manuals show us the fascist way of social medicine.

In October 1894 was held in Milan the III Congrés International des Accidents du Travail et des Assurances Sociales. 747 delegates participated, coming from 16 nations. In this Congress the theme of a special medical assistance in the industrial accidents was approached for the first time in Italy. In March, 1895 also the Milanese trade union office dealt him with the matter, organizing a specific congress. The trade union movement realized the necessity to approach the problem of industrial accidents. 170 delegates participated to the Congress. The 1895 Congress also represented the occasion for the dawning feminist movement to come into contact with the working class. In 1896 the Association for the Medical Assistance in the Industrial Accidents in Milan was founded. The Association started up a clinical institute. At the end of the XIXth century, with prevention and therapeutic interventions the problem of industrial accidents was faced.

The payload complement on Spacelab 1 included a spectrometer for observations of the brighter cosmic x-ray sources. The primary scientific objective was to study the detailed spectral features of cosmic x-ray sources and their associated temporal variations over a wide energy range from about 2 to 80 kiloelectron volts. The instrument, based on the gas scintillation proportional counter, had a geometrical area of some 180 square centimeters with an energy resolution of about 9 percent at 7 kiloelectron volts. The results presented here show new results from two galactic binary x-ray sources, Cygnus X-3 and Centaurus X-3, and from the Perseus cluster of galaxies. The excellent energy resolution of the instrument permits line features to be identified in these sources with unprecedented quality.
