This paper discusses the content of the cadre file of Henri H. Stahl preserved in the Archives of the University of Bucharest's Rectorate. In the form in which it has been preserved after 1989, the personnel file of H.H. Stahl seems, from several points of view, atypical. If we compare it with the cadre files of the 1950s, it surprises by the apparent "goodwill" of the communist cadres towards H.H. Stahl. This ideological solicitude is manifested in the interpretation given to main cultural and political events in H.H. Stahl's life. In other circumstances such political past could be labeled as unusable in a communist context. Equally curious and noteworthy is the issue of the ethnic origin attributed (and not necessarily real or assumed by the one described in the file), more precisely the issue of Stahl's nationality (Jewish) which was recorded in the file. Analyzing Stahl cadre file we can wonder if the integrity of this dossier has not been compromised by removing, extracting or modifying documents by the personel staff services or by someone else.

To satisfy the growing and diversified demand for food from the population, all compound feed factories propose to obtain finished products of the best possible quality, in the shortest time and at the lowest possible cost. Given the complexity of the activities performed during the technological flow from a compound feed factory, this article proposes monitoring the thermotechnical parameters of installations by made experimental measurements using sensors installed at critical points. The measurements shown in this article were made during the production of two compound feed types, because each recipe involves different work parameters. The scope of this monitoring of thermotechnical parameters is to confirm the reliability of the devices that ensure the automated control of the equipment, so as to respect the European Union norms regarding the protection of staff and the environment.

The production of compound feed is very necessary for the nutrition of animals from livestock farms, both for the contribution of the good quality nutrients, and also for the reduction of animal products costs. For realizing the European Union's rules regarding the processing of cereal products is necessary the endowing of all production capacities with modern and performance equipments, with high degree of mechanization, automation and computerization, with high productivities and with low specific consummations. Therefore it must be designed performing working installations whose functioning will be checked through experimental modeling so as to match the European rules.

The technological process of obtaining the compound feeds involves the mixing of the milled cereals in the mills of the work installation with protein flours, mineral salts and vegetable oils. During the activities of grinding cereals and obtaining granules of finished product, it can be detached fine particles which forming the dust that is released in the air. This article analyzes the technological process for the preparation of compound feeds with accent on the stages of grinding, granulation and homogenization of the finished product, for study the problems who can appear due to the eliminated dust in the air by the working installations. The measurements effectuated attest the efficiency of the use of special filtres and automatized control systems of dust concentrations according to the pollution norms imposed by the European Union in order to protect the environment.
