Experimental study of the vidicon system for information recording using the wide-gap spark chamber of gamma - telescope gamma-I

The development of the gamma ray telescope is investigated. The wide gap spark chambers, used to identify the gamma quanta and to determine the directions of their arrival, are examined. Two systems of information recording with the spark chambers photographic and vidicon system are compared

Parental social mobility and the status aspirations of junior high school students

Thesis (Ph.D.)--Boston UniversityThe purpose of the present study is to investigate the relationship between patental social mobility and (a) subjects' status aspirations, (b) perceived parental status expectations. The subject population utilized consisted of 263 male students in the final year of junior high school. Two major hypotheses were tested by this investigation. Hypothesis I was that the level of subjects' status aspirations would be found to be a positive monotonic function of the extent of parental social mobility. Hypothesis II was that the level of perceived parental status expectations would be found to be a positive monotonic function of the extent of parental social mobility. [TRUNCATED

Social Work Practice and the Social Context

Any effort to define appropriate tasks and directions for social work practice must necessarily come to grips with some analysis of the particular social-political-historical situation within which that practice is being formulated. Too often it seems as though we attempt to define practice abstracted from the particular period in which that practice takes place. It is true, on the one hand, that it is important to develop generic principles of practice. Similarly, it is true that the definition of the social work task is not a matter left solely to the discretion of the profession. In fact, the profession may have a relatively small voice, at any moment, in defining its task. On the other hand, the separation of practice formulations from the specifics of the historical moment leads to blind technicism and to the charge of irrelevance which has often and sometimes accurately been leveled at the profession. And, while we may have far from the definitive influence on our own practice, if we are not conscious of directions we value and do not press for them to the extent possible, then we do not act with the fullest responsibility for human service

The ALTCRISS Project On Board the International Space Station

The Altcriss project aims to perform a long term survey of the radiation environment on board the International Space Station. Measurements are being performed with active and passive devices in different locations and orientations of the Russian segment of the station. The goal is perform a detailed evaluation of the differences in particle fluence and nuclear composition due to different shielding material and attitude of the station. The Sileye-3/Alteino detector is used to identify nuclei up to Iron in the energy range above approximately equal to 60 MeV/n; a number of passive dosimeters (TLDs, CR39) are also placed in the same location of Sileye-3 detector. Polyethylene shielding is periodically interposed in front of the detectors to evaluate the effectiveness of shielding on the nuclear component of the cosmic radiation. The project was submitted to ESA in reply to the AO the Life and Physical Science of 2004 and was begun in December 2005. Dosimeters and data cards are rotated every six months: up to now three launches of dosimeters and data cards have been performed and have been returned with the end expedition 12 and 13
