Obtaining holographic volume gratings with high diffraction efficiencies that can be used under white light has been a serious problem for the polyvinyl alcohol-acrylamide-based photopolymers developed by other researchers. In this paper we propose to eliminate the residual monomer in…

Kogelnik's coupled-wave (CW) theory has been used for decades to predict the diffraction efficiency of volume diffraction gratings. Although this theory has been applied with success to volume diffraction gratings recorded under a great variety of experimental conditions, its predictions…

In the 19th century it was difficult for the growing number of medical practitioners in North America to access current medical literature. Various ways were suggested to solve this problem; one of them was the creation of physician-run medical library…

El trabajo comienza por plantear un diseño teórico de los procesos de toma de decisiones de los Estados en materia de política exterior, para luego adentrarse en el análisis teórico de la guerra como institución, sobre las ideas de Von…

This thesis examines images of martial women as they were produced in the biography column of the late Qing journal Nüzi shijie (NZSJ; 1904-1907). By examining the historiographic implications of revised women's biographies, I will show the extent to which…

The Serbian education system severely deteriorated after a series of conflicts and NATO bombings dismantled the nation from the 1990's-2000. Although violence is not uncommon to schools around the world, researchers have demonstrated that the long term effects of war…

This thesis attempts to historicize our understandings of economic rationality and economic action, specifically in the period leading up to the South Sea Bubble of 1720, an event which seemingly remains shrouded in mystery. The fundamental question addressed is what…

La tesis recoge el trabajo desarrollado para implementar un sistema de digitalización de señales electrónicas procedentes de un detector de centelleo, tipo phoswich, y el estudio de la forma de éstas para poder determinar el tipo de radiación ionizante que…

15-Deoxy-Δ12,14-prostaglandin J2 (15dPGJ2) has been recently proposed as a potent anti-inflammatory agent. However, the mechanisms by which 15dPGJ2 mediates its therapeutic effects in vivo are unclear. We demonstrate that 15dPGJ2 at micromolar (2.5–10 µM) concentrations induces the expression of heme…

The Doppler effect is a phenomenon which relates the frequency of the harmonic waves generated by a moving source with the frequency measured by an observer moving with a different velocity from that of the source. The classical Doppler effect…
