A powered gravity assist around the sun, also known as an Oberth maneuver, has potential to achieve a solar system escape velocity of 20 astronomical units (AUs) per year, which is desirable for interstellar mission. Unfortunately, current heat shields and propulsion technology struggle outperform unpowered Jupiter assist, let alone AUs/year, due unfavorable mass tradeoffs. We are therefore dev...
Blue light-emitting diodes (LEDs) in liquid crystal displays emit high levels of blue light, exposure to which is harmful to the retina. Here, we investigated the protective effects of colored lenses in blue LED light-induced damage to 661W photoreceptor-derived cells. We used eight kinds of colored lenses and one lens that reflects blue light. Moreover, we evaluated the relationship between th...
In this paper, we propose real-time communication middleware which supports data dissemination with proxy extension. To fulfill stringent QoS requirement such as timing constraint, we employ push-based data delivery approach and real-time channel. Furthermore, by making the most of connected clients, we could permit the increased number of clients and extend the scalability. Since it is also de...
in this study, the relationship between teachers’ creative and critical thinking skills and their reflectivity in teaching was investigated. to this end, three questions were raised. these questions were intended to determine whether there was a significant relationship between teachers’ creative thinking skills and their reflectivity in teaching; whether there was a significant relationship be...
A fully automatic spray-LBL machine with monitoring the real time growth of multilayer films using Quartz Crystal Microbalance (QCM) techniques was newly developed. We established fully automatic spray layer-by-layer method by precisely controlling air pressure, solution flow, and spray pattern. The movement pattern towards the substrate during solution spraying allowed fabrication of a nano-sc...
Head computed tomography is a common diagnostic examination, which may cause lenticular opacity and cataracts. Cataract induction is one of the non-stochastic effects of radiation, that happens at threshold dose of 0.5 Gy. Recent studies illustrate that only irradiation to the sensitive (germinative) zone of the lens is a prerequisite to cataract development. Recently, the dose values absorbed ...
