All-optical angular sensing based on holography multiplexing with spherical waves

Abstract: An all-optical angular sensing system based on volume ho- lography is proposed and demonstrated, where a divergent spherical wave is the reference and reading beam for writing and testing, respec- tively. Under the paraxial condition, analysis shows that angular selectiv- ity is nearly independent of the distance between the hologram and the light source. By choosing an appropriate distance, the entire energy of the source (e.g., an LED) can be employed while maintaining the same resolution for precise angular sensing. © 2002 Society of Photo-Optical Instru- mentation Engineers.

The role of informal learning activities in improving L2 lexical access and acquisition in L1 Arabic speakers learning EFL

Abstract: Case studies in lexical uptake suggest that some well reported language learning strategies, such as extensive reading and listening to songs, can be quantified accurately in terms of time spent on...

Functions and oxidative stress status of leukocytes in patients with nephrotic syndrome.

Abstract: This study was conducted to establish the functions and oxidative stress status in leukocytes of adult patients with nephrotic syndrome. Thirty adult patients with nephrotic syndrome and 32 controls were included. Phagocytosis ability, the killing ability of the micro-organism phagosited of polymorphonuclear leukocytes (PMNL) and monocytes, along with oxidative stress parameters of PMNLs were assessed. There was no statistically significant difference in phagocytosis function of PMNLs and monocytes of patients when compared to those of controls. PMNL burst activities of the patient and control groups also showed no difference; however, the monocyte burst activities of patients were significant (p = 0.012). The glutathione peroxidase (GSH-Px) activities in PMNLs of the patients with nephrotic syndrome were significantly higher (p = 0.026) when compared to those of controls. In comparison with those of the control subjects, the patients had also higher selenium levels in their PMNLs (p < 0.001). Although PMNL malonyldialdehyde (MDA) levels of the patients seem to be higher than those of controls, the difference had no statistical significance (p = 0.071). Conclusively, in the patients with nephrotic syndrome, PMNLs appear to be exposed to an oxidative stress as indicated by their increased GSH-Px activities and selenium content. However, PMNLs in nephrotic syndrome patients seem to be coping with the insulting oxidative stress, as suggested by their near-normal MDA productions. Furthermore, these data suggest that nephrotic syndrome appears not to have an influence on phagocytosis and killing abilities of granulocytes and monocytes as long as these cells can overcome the oxidative stress to which they are exposed in this disease.

Physical-geographic factors of terrain trafficability of military vehicles according to Western World methodologies

Abstract: This paper analyses the existing state, limitations, and possibilities for research of physical-geographic factors in the context of terrain trafficability of military vehicles in order to support the military decision-making process regarding planning movements of military forces. This paper shows which models and research methodologies were used to ascertain how physical-geographical factors influence vehicle cross-country mobility. Research has shown that slope has been used most frequently as a parameter, followed by soil properties, surface roughness, watercourses, vegetation types, and climatic-meteorological conditions. The quality of the results achieved so far has been largely determined by the quality and accuracy of the input data and by the various methods used in the models. Recent studies have shown that the Geographic Information System (GIS) unifies the issues determining vehicle terrain trafficability, as it displays all possibilities in a single platform.
