PURPOSE Our aim was to compare the 1 year efficacy and safety results of intravitreal bevacizumab (IVB) in two prospective, consecutive groups of patients with macular edema (ME) following branch retinal vein occlusion (BRVO). PATIENTS AND METHODS Twenty-five eyes with ME after BRVO received one IVB injection (single-injection group) and 27 eyes received three monthly IVB injections (three-in...

Using frictional force microscopy (FFM), the friction surface characteristics were compared between twisted nematic (TN) mode and vertical alignment (VA) mode alignment films (AFs). The friction asymmetry was detected depending on temperature conditions on TN mode AF, but not on VA mode AF. The difference between two modes was explained by leaning intermolecular repulsion caused by the pre-tilt...

The subject of optimal control is researched during the insertion of the space vehicle into the orbit of Mars artificial satellite with the preliminary aerodynamic braking in the atmosphere. The space vehicle control methodology of roll angle and angle of attack is elaborated. Variational problems are solved for minimization of necessary power inputs and maximization of space vehicle re-entry c...

Objective: A cervical epidural steroid injection is one of the most commonly performed interventions to manage chronic neck pain and cervical radiculopathy. Despite its many severe complications, cervical transforaminal epidural steroid injection (CTFESI) is a clinically necessary modality for managing neck pain and cervical radiculopathy. We aimed in this study to find a safer optimal needle e...

Stress sensitivity is a very important index to understand the seepage characteristics of reservoir. In this study, dedicated experiments and theoretical arguments based on visualization porous media are used assess effects fracture angle, spacing, relevant elastic parameters principal value permeability tensor. The apertures at different angles show change rates, which influence relative for s...

Basic electrowetting theory predicts that a continued increase in applied voltage will allow contact angle modulation to zero degrees. In practice, the effect of contact angle saturation has always been observed to limit the contact angle modulation, often only down to a contact angle of 60 to 70. The physical origins of contact angle saturation have not yet been explained successfully and uneq...

Abstract This paper studies cosmic-ray (CR) transport in magnetohydrodynamic (MHD) turbulence. CR is strongly dependent on the properties of magnetic We perform test particle simulations to study interactions with both total MHD turbulence and decomposed modes. The spatial diffusion coefficients pitch angle scattering are calculated from trajectories Our results confirm that fast modes dominate...

In recent days, current research is going in alternative fuels due to increase in global warming and pollution in all over the world and also very stringent emission norms. In this way, the study on spray progress plays an important role in improving complete combustion and emission of fuel, because it is directly affects the air-fuel mixture formation. The macroscopic spray characteristics of ...
