The grinder worked flawlessly for over a year and then it broke 2 weeks ago. The unit was 2 months out of warranty. I checked Baratza's website and they have a repair program. The price for reasonable ($45 for repair.) I figure it was worth the repair since a new one is more expensive one year later. I shipped it to the service center with the ...

The incidence varied with the frequency of contact lens replacement. The contact lens replacement schedule ranged from 1 day to 12 weeks. In those patients replacing their contact lenses every 4 weeks or at a longer interval, the incidence of GPC was 36%, while for patients who replaced their lenses more frequently, the incidence was 4.5%.

A high speed lens grinding and polishing machine comprising a lap tool holder and a gimbal mounted polishing element disposed at its lower extreme in a spherical bearing permitting a lens blank holder to follow the contour of the lens during the polishing process. Relative movement between the lap tool holder and lens blank holder is generated by a rotary drive operatively coupled to the ...

Abstract. We have carried out a systematic search for galaxy-scale strong lenses in multiband imaging from the Hyper Suprime-Cam (HSC) survey. Our automated pipeline, based on realistic strong-lens simulations, deep neural network classification, and visual inspection, is aimed at efficiently selecting systems with wide image separations (Einstein radii θ E ∼ 1.0-3.0″), intermediate ...

Focusing especially on contact lenses, Eye & Contact Lens also covers dry eye disease, MGD, infections, toxicity of drops and contact lens care solutions, topography, cornea surgery and post-operative care, optics, refractive surgery and corneal stability (eg, UV cross-linking). Peer-reviewed, indexed, and published monthly online, it is a highly respected scientific journal in its field.

In fact, maybe everyday photography (the non-abstract kind) can gain something from adopting this perspective more often – composing your scene as if it is an abstract collection of lines, shapes, colors, textures, and harmonies, culminating to form your chosen emotional message – with the literal nature of your scene almost a secondary fact.

Abstract: An optical lens grinder device including a main base and a lens carriage pivotally slidably connected along one edge to the base. A first motor mounted on the base drives a pair of closely spaced apart grinder wheels, one for shaping and sizing a lens blank, the other for peripherally beveling the edges thereof. ...

Abstract art is uniquely modern. It is a fundamentally romantic response to modern life - rebellious, individualistic, unconventional, sensitive, irritable. ~Robert Motherwell This week we invite you to break the rules and go beyond the traditional realistic image of an object, scene, or element. For Lens-Artists Photo Challenge #74, we are going "Abstract."

Abstract. The intersection of secular, Western intellectual property law and Islamic law is undertheorized in legal scholarship. Yet the nascent and developing non-Western law of one form of intellectual property—patents—in Islamic legal systems is profoundly important for transformational innovation and economic development initiatives of Muslim-majority countries that comprise nearly …

He earned his living as a humble lens-grinder. He died, in February 1677, of consumption, probably aggravated by fine glass dust inhaled at his workbench. His philosophy is summarized in the Ethics, a very abstract work, which openly expresses none of the love of nature that might be expected from someone who identified God with nature.

Abstract: Summary form only given.Intense ultrafast laser sources in the mid-IR have attracted in the recent years lot of attention in strong-field physics. A possible implementation for such sources relies in: a) the generation of a short IR seed by intra-pulse difference frequency generation (DFG) of a broadband continuum generated in an hollow-core fiber (HCF); b) optical parametric ...

Typical batch sizes are large – e.g. up to 100,000. Productivity is very high, with 10 to 100 pieces/minute for face grinding and 2-5 pieces/minute for shoe-centerless grinding. The changeover times are long: 1-4 hours for the face grinder; 3-6 hours for the OD, flange and ID grinders; and 1-2 hours for the superfinisher.

A blocking technique and apparatus are used to mount a partially finished lens or other component to an arbor, which is useable to hold the partially finished lens for subsequent machining or mechanical operations. The blocking of the partially finished lens occurs on the same axes of the multi-axis machining device that were used to generate the partially finished lens.

Abstract. The deployment of smart contracts within the European zone could fluidify economic transactions. It also risks fragmenting the Digital Single Market ("DSM"). This conundrum calls for a constructive response to preserve both the benefits brought by smart contracts and a strong DSM.

The lens on these helmets automatically switches from light to dark the instant you start welding. Welding Helmets Providing greater safety while welding than face shields, these helmets have an outer filter lens cover for protection from scratches and weld spatter.

To achieve a much closer focus that can magnify tiny objects or details and capture a life-sized (or even bigger) image, you'll need to use your camera's Macro mode or get a good macro lens. 4. Shoot through objects. Using a makeshift lens "filter" can …
