Soft contact lenses are widely used for correction of refractive errors and in diseases related to corneal surface irregularities. In this case series we have used soft contact lenses in treatment of patients having bullous keratopathy, corneal ulcer, dry eye, trichiasis and corneal perforation. Soft contact lenses were found to be superior than conventional method of treatment and they have re...

The goal of studying the vehicle suspension systems is to reduce the vehicle vibrations which are due to the irregularities of road levels and the fluctuations in the vehicle velocity. These vibrations are transferred to the body and occupants of vehicles through the suspension system. In general, the main function of an active suspension system is to support the vehicle body by reducing the in...

We measure the interaction of a single superfluid vortex with surface irregularities. While vortex pinning in superconductors usually becomes weaker at higher temperatures, we find the opposite behavior. The pinning steadily increases throughout our measurement range, from 0.15Tc to over 0.5Tc. We also find that moving the other end of the vortex decreases the pinning, so we propose Kelvin wave...

3D printing, as an additive process, offers much more than traditional machining techniques in terms of achievable complexity of a model shape. That fact was a motivation to adapt discussed technology as a method for creating objects purposed for aerodynamic testing. The following paper provides an overview of various 3D printing techniques. Four models of a standard NACA0018 aerofoil were manu...

Osteochondral lesions most commonly occur about the knee but may affect any articular surface of the pediatric appendicular skeleton. Osteochondral lesions include osteochondritis dissecans, osteochondral fractures, and osteochondral abnormalities associated with secondary processes such as Legg-Calvé-Perthes disease. These abnormalities should not be confused with normal subchondral irregulari...

The SuperDARN radars map high-latitude ionospheric plasma drift velocities by measuring the Doppler frequency shift of HF signals scattered by decameter electron density irregularities. In many cases the ionospheric returns are contaminated by strong scatter from the ground or sea surface. In this paper we develop and test a two-component fitting algorithm to separate ionospheric and surface sc...

Assurance of surface glossiness is one of the most important factors in the production of stainless steel strips, but the surface glossiness has been evaluated by off-line measurement and visual inspection. For the purpose of on-line evaluation of the surface glossiness, an optical measurement method of the surface glossiness and a neural network-based discriminant method have been developed. F...

The management of nasal deformities especially after rhinoplasty is a challenge. Postsurgical edema may last 6-8 months, causing aesthetic irregularities and nose deformities. The aim of this study is to present the correction of minor nose deformities secondary to rhinoplasty using hyaluronic acid subdermal injections. Eleven patients were treated between 2009 and 2011 with subdermal injection...

In this paper, we propose a 3D reconstruction approach using shape-based interpolation and contourbased extrapolation. This approach aims to generate a 3D geometric model of a human shoulder from a sequence of MR parallel 2D cross-sections. While interpolation generates intermediate slices between every pair of adjacent input slices, extrapolation performs a smooth closing of the external surfa...

BACKGROUND Injectable fillers are sometimes necessary to correct slight skin irregularities. However, there have been reports of necrosis after injection of alloplastic materials and heterogeneous transplants. On the other hand, the advantages of autogenous tissue grafts over those fillers are well established. Volumetric reshaping of the face with autologous tissue injection is a popular and r...
