Tesis para optar al grado de Magíster en Filosofía mención Epistemología / La controversia entre JürgenHabermas y NiklasLuhmann estuvo vigente durante aproximadamente tres décadas. El punto de inicio fue una obra conjunta publicada en 1971 (Teoría de la sociedad o tecnología social). El desenlace, el fallecimiento de Luhmann en 1998. Durante este periodo, la obra de ambos autores se mantuvo en constante diálogo, adquiriendo la relevancia de debates tan recurridos como el efectuado entre Karl Popper y Theodor Adorno. En esta investigación pretendemos mostrar que esta controversia (inserta en el contexto no tanto de la filosofía sino de las ciencias sociales) no es ajena al pensamiento filosófico, sino que representa una instancia de renovación de las principales ideas filosóficas en torno a la modernidad, inauguradas por Kant y Hegel. Nuestra postura es que en Habermas y Luhmann se confrontan dos posibilidades de iniciar el pensamiento filosófico y teórico, como algo apriorístico o como un resultado.

An important problem confronting the designer of machines and structures which may be subjected to suddenly applied loads is the determination of the actual forces which the members must withstand. This investigation has been confined to a study of impact forces on beams in simple flexure. Margerum (American Society of Testing Materials, 1922) suggested a method whereby the maximum load might be found by obtaining indentations on a calibration bar attached to the moving head of the impact machine, and suggested using this in conjunction with an autographic stress strain diagram. Tests have been made upon both notched and unnotched bars, but the results were not satisfactory. It has been proposed that an accelerometer be designed with which the acceleration could be measured directly. After the acceleration is known the force producing the acceleration can be calculated. The acceleration of a point can be determined by a double differentiation of a space-time diagram. This method is being employed in this thesis. / M.S.

Rye seedlings grown on differently fertilized plats at Chatham, Virginia, and at Fishersville, Virginia, for the year 1928, and tested by the Neubauer seedling method for phosphorus gave no clue to the amount and availability of the phosphatic fertilizer added. Therefore, the Neubauer seedling method as devised by Neubauer did not prove to be of value in determining the phosphorus availability of Virginia soils under the conditions prevailing in 1928. / M.S.
