purpose: to study the effect of phototherapeutic keratectomy (ptk) in the treatment of various superficial corneal pathologies. methods: we performed a nonrandomized, prospective study on patients who presented with superficial corneal disease and/or poor vision. fifty eyes were included recurrent corneal erosion (rce): 25 eyes, salzmann’s nodular degeneration: 9 eyes, spheroidal degeneration: ...
in fact, this study focused on the following questions: 1. is there any difference between the effect of functional/notional approach and the structural approaches to language teaching on the proficiency test of efl learners? 2. can a rather innovative language test referred to as "functional test" ge devised so so to measure the proficiency test of efl learners, and thus be as much reliable an...
Osteoclast activation is a critical cellular process for pathological bone resorption, such as erosions in rheumatoid arthritis (RA) or generalized bone loss. Among many factors triggering excessive osteoclast activity, cytokines such as IL-1 or tumour necrosis factor (TNF)-alpha play a central role. New members of the TNF receptor ligand family (namely receptor activator of nuclear factor-kapp...
The advances of remote sensing techniques allow for the generation dense point clouds to detect detailed surface changes up centimeter/millimeter levels. However, there is still a need an easy method derive such based on digital elevation models generated from while taking into consideration spatial varied uncertainty. We present straightforward method, Las2DoD, quantify change directly with sp...
When one removes a sector from a circular sheet of paper and glues the edges back together, the resulting shape is approximately conical. Despite the simplicity of the setup, a proof of this ’fact’ starting from basic models for thin elastic sheets has not been found yet. In this talk we investigate the scaling of the elastic energy with the sheet thickness h for this setting. Our main innovati...
Objectives. Ultrasonography (US) is a sensitive tool for detecting erosions in patients with RA. The wrist is usually involved in the RA process, where the distal ulna with its superficial localization is easily accessible for US examination. In this longitudinal study, we wanted to examine the presence, localization and development of erosions at the distal ulna by US in patients with recent o...
1.1 introduction “i see translation as the attempt to produce a text so transparent that it does not seem to be translated. a good translation is like a pane of glass. you only notice that it’s there when there are little imperfections- scratches, bubbles. ideally, there shouldn’t be any. it should never call attention to itself.” “norman shapiro” (venuti, 1995:1) edward fitzgerald is the br...
AIM To investigate by electron microscopy the plane of separation of the epithelial sheet from its substratum in the procedure of alcohol delamination (ALD) in patients with recurrent corneal erosion syndrome. METHODS Ten cases of recurrent corneal erosions (RCE) secondary to trauma and seven cases related to map-dot-fingerprint dystrophy (MDFP) were treated with ALD. The epithelial sheets ob...
The purpose of this paper is to present an advanced method for welding fine wire to metal sheet, namely laser indirect shock welding (LISW). This process uses silica gel as driver sheet to accelerate the metal sheet toward the wire to obtain metallurgical bonding. A series of experiments were implemented to validate the welding ability of Al sheet/Cu wire and Al sheet/Ag wire. It was found that...
