Microwave plasma sources at atmospheric pressure have a variety of different applications and therefore are object of intense research. This paper covers the spectroscopic investigation of an atmospheric pressure microwave plasma torch and experiments concerning the abatement of the perfluorinated compounds CF4 and SF6. By means of optical emission spectroscopy the gas temperature of a humid ai...

There is a need for a convenient, clinically applicable test of glare disability which can be used in the preoperative evaluation of patients with cataract. In this study, contrast sensitivity (using the Pelli-Robson letter chart), near vision, and visual acuity were compared, with and without the introduction of a glare source in 70 patients with cataract, 15 with intraocular lenses, and 19 co...

An argon plasma generated by a torch arc discharge with pressure of 50 torr and power of 800 watts is characterized by a single and Mach probes. A uid model for the owing un-magnetized plasma with the generic two-dimensional feature is established by taking moment of one-dimensional Boltzmann transport equation with contribution of ionization and ion-neutral collisions. Using a new relation b...

Zika virus (ZIKV) is a mosquito-borne arbovirus from the family Flaviviridae, which had caused some epidemics since its discovery in 1947 without any significant impacts on public health. In 2015, however, a 20-fold increase in congenital microcephaly cases in northeastern Brazil was attributed to prenatally acquired ZIKV infection. Traditionally, TORCH agents have 4 common characteristics incl...

This paper presents cltorch, a hardware-agnostic backend for the Torch neural network framework. cltorch enables training of deep neural networks on GPUs from diverse hardware vendors, including AMD, NVIDIA, and Intel. cltorch contains sufficient implementation to run models such as AlexNet, VGG, Overfeat, and GoogleNet. It is written using the OpenCL language, a portable compute language, gove...

An optical method was used to determine the axial velocity of plasma jets produced by a DC plasma spray torch. Different experimental conditions were tested in order to systematically study the influence of the working parameters on the plasma velocity. In this way, the arc current ranged between 200 and 600 A, the gas flow rate between 30 and 80 slm, and the internal nozzle diameter between 6 ...

China’s relations with the West deteriorated dramatically following the Tibet and Olympic torch relay controversies in the spring of 2008. Because of its focus on the balance of material power, realist International Relations theory can do little to help us understand such developments. Instead, it is the political psychology of international relations that provides the most leverage on the rol...

Since its inception in the early 1990s the enactive approach to perception has been generating an extensive amount of interest and debate in the cognitive sciences. The original idea behind this approach can be summarized by the claim that perceiving is not about the recovery of a perceiver-independent world, but rather consists in perceptually guided, embodied action. More recently, the approa...

As one of techniques to improve a penetration depth in gas tungsten arc welding, it has been proposed that carbon dioxide is applied as shielding using double torch. Two types gases can flow independently the torch: inner and outer gas. The purpose this study was clarification behavior establish guideline for controlling oxygen contamination which affects toughness welded part formed by welding...
