The history of human experimentation in the twelve years between Hitler's rise to power and the end of the Second World War is notorious in the annals of the twen- tieth century. The horrific experiments conducted at Dachau, Auschwitz, Ravens- brueck, Birkenau, and other National Socialist concentration camps reflected an extreme indifference to human life and human suffering. Unfortunately, they do not reflect the extent and complexity of the human experiments undertaken in the years between 1933 and 1945. Following the prosecution of twenty-three high-ranking National Socialist physicians and medical administrators for war crimes and crimes against humanity in the Nuremberg Medical Trial (United States v. Karl Brandt et al.), scholars have rightly focused attention on the nightmarish researches con- ducted by a small group of investigators on concentration camp inmates. Less well known are alternative pathways that brought investigators to undertake human ex- perimentation in other laboratories, settings, and nations.

We present a novel approach for the optical manipulation of neutral atoms in annular light structures produced by the phenomenon of conical refraction occurring in biaxial optical crystals. For a beam focused to a plane behind the crystal, the focal plane exhibits two concentric bright rings enclosing a ring of null intensity called the Poggendorff ring. We demonstrate both theoretically and experimentally that the Poggendorff dark ring of conical refraction is confined in three dimensions by regions of higher intensity. We derive the positions of the confining intensity maxima and minima and discuss the application of the Poggendorff ring for trapping ultra-cold atoms using the repulsive dipole force of blue-detuned light. We give analytical expressions for the trapping frequencies and potential depths along both the radial and the axial directions. Finally, we present realistic numerical simulations of the dynamics of a 87Rb Bose-Einstein condensate trapped inside the Poggendorff ring which are in good agreement with corresponding experimental results.

New ways of sociability can be perceive in a historical context marked by the social change. The investigation developed by this thesis follow this idea, pointing the emergency of social relations established between individuals in drift. The foremost aim of this research was to assay, using a case study, the bonds constructed among the people that attend the Terminal Central - Pratic Shopping of Uberlândia-MG, the main responsible for the reception and distribution of public transport of the city. With the growth of the urban centers, their population became attractive objects of analysis in the social science field and the understanding of the city, in their core, by the dwellers displacement. Thus, after the separation of the people that use the Terminal Central in seven groups (students, families and couples, elderly, deaf and/or mute, employees of the stores in Terminal and of the bus companies), their interactions tried to be understood, by identifying the similarity with the sociability in traffic studies. In places with a great flow of people, the sociability in traffic suggests bonds of friendship, kindness, as foray, impersonality, frailty and the sudden break of contact.
