Background/Aim. Stereo vision guarantees good and is one of the three main elements binocular vision, besides simultaneous perception fusion. It represents third degree enables estimation distance, depth, space between objects, i.e., allows a three-dimensional image, which crucial for pilot. The aim this study was to investigate effect +Gz acceleration on stereo in pilots air force student pilo...

Composite materials were manufactured to obtain singular properties be used as in electrochemical driven energy systems. An evaluation was performed on electro-spun nylon 6,6 fibers (Ny), with different concentrations of tetra-para-amino-phenyl porphyrin (PP) and graphene oxide (GO) composite coating over stainless steel (SS), immersed 1M H2SO4 aggressive sulfuric acid solution. Different film ...

Purpose The purpose of this study was to evaluate the effect of gravity acceleration on choroidal and retinal nerve fiber layer (RNFL) thickness using swept-source optical coherence tomography (SS-OCT). Methods Thirteen healthy volunteers who planned to participate in human centrifuge training as part of the flight surgeon selection process enrolled this study. During centrifuge training, gra...

We present a detailed theoretical and experimental study of the rotation plane polarization light traveling through gas fast-spinning molecules. This effect is similar to drag phenomenon predicted by Fermi century ago it mechanical analog Faraday effect. In our experiments, molecules were spun up an optical centrifuge brought super-rotor state that retains its for relatively long time. Polariza...

heat-inactivated fetal calf serum in an atmosphere of 5% CO2 and air at 37°C and subcultured every 4 days. Cells were grown it) monolayers on flying coverslips in Leighton tubes or in plastic T flasks for 2 days before the addition of 15 pg/nil of quinacrine to the culture medium. Cells were exposed to quinacrine for periods up to 2 hours ; some specimens were allowed to recover in medium with...

Persistent pulmonary air leak affects between 10-15% of surgical procedures, generally requiring management through the use conventional chest drainage systems (water-sealed pleural chamber) subjective interpretation due to poor detection sensitivity. leaks, resulting in increased morbidity, hospital stay, and costs.

Microfluidics is an established multidisciplinary research domain with widespread applications in the fields of medicine, biotechnology and engineering. Conventional production methods of microfluidic chips have been limited to planar structures, preventing the exploitation of truly three-dimensional architectures for applications such as multi-phase droplet preparation or wet-phase fibre spinn...
