Aspheric Lens: Aspheric Lens: An aspheric lens is designed for aberration correction. With the help of aspheric lens, the image formed is distortion free. An aspheric lens is a lens whose surfaces profile neither a portion of a sphere nor of a circular cylinder. Since it is not spherical, the conventional processes no longer apply to making aspheric surfaces. This is why aspheric cost many times what spherical surfaces do.

Aseptic processing Aseptic processing of sweet potato puree and filling sterile plastic bag. Sterility is achieved with a flash-heating process (temperature between 195 and 295 °F (91 to 146 °C)), which retains more nutrients and uses less energy than conventional sterilization techniques such as retort or hot-fill canning.septic processing makes worldwide export and import of new, economical and safe food products possible. Bag-In-Box technology is commonly used because it provides strong containers that are lightweight and easy to handle prior to being filled. Other common package types are drink boxes and pouches.

Hemispheric Syndromes Hemispheric syndrome is otherwise known as anterior circulation syndrome. It is the result of a large vessel stroke, and occurs when there is proximal occlusion of the int carotid artery, middle and/or anterior cerebral arteries supplying the cerebral hemispheres.

What is the difference between asthenosphere and mesosphere? noun, Geology. 1. the region below the lithosphere, variously estimated as being from fifty to several hundred miles (eighty-five to several hundred kilometers) thick, in which the rock is less rigid than that above and below but rigid enough to transmit transverse seismic waves.

What is the lithosphere and asthenosphere? Best Answer: The lithosphere consists of the heavy oceanic and lighter continental crusts, and the uppermost portion of the mantle. The asthenosphere is the region in the upper mantle characterized by low-density, semiplastic (or partially molten) rock material chemically similar to the overlying lithosphere.

The Asthenosphere is a part of the crust or the mantle ? Best Answer: asthenosphere, a relatively narrow, mobile zone of the mantle made of molten and solid rock that flows from convection currents to carry the lithospheric plates above.. . The asthenosphere is a part of the upper mantle that exhibits plastic properties. It is located below the lithosphere (the crust and upper mantle), between about 100 and 250 kilometers deep.

- The asthenosphere is a weaker layer that flows right underneath the lithosphere. Together, the lithosphere and the asthenosphere comprise what scientists refer to as the earth’s mantle.There are two different kinds of lithosphere which together make up the earth’s surface, or crust. The oceanic lithosphere is essentially what is referred to as the ocean floor.he asthenosphere is a weaker layer that flows right underneath the lithosphere. Together, the lithosphere and the asthenosphere comprise what scientists refer to as the earth’s mantle.

- The crust and the upper layer of the mantle together make up a zone of rigid, brittle rock called the Lithosphere. The layer below the rigid lithosphere is a zone of asphalt-like consistancy called the Asthenosphere.

What is the asthenosphere? The asthenosphere is that part of the Earth which is viscous and undergoes ductile deformation and convection on a geological time scale. It is part of the upper mantle and is approximately 600 km thick laying below the lithosphere at a depth of around 100 to 200 km and it's base is around 700 km deep.

Aspheric Lenses Aspheric Lenses. Aspheric lenses are defined as lenses that are non-spherical. This non spherical surface encompasses all kinds of lenses from aspheric, atoric, progressive, and aphakic. So if all these lenses fall in the definition of an aspheric lens, how do we further define and differentiate aspheric lenses in all their forms. Aspheric

What is the asthenosphere? The asthenosphere is the highly viscous, mechanically weak and ductilely deforming region of the upper mantle of the Earth.The asthenosphere is generally solid although some of its regions could be melted (e.g. below mid-ocean ridge). The lower boundary of the asthenosphere is not well defined. The thickness of the asthenosphere depends mainly on the temperature is involved in plate tectonic movement and isostatic adjustments.

- Polar stratospheric cloud. Polar stratospheric clouds or PSCs, also known as nacreous clouds (/ˈneɪkriː.əs/, from nacre, or mother of pearl, due to its iridescence), are clouds in the winter polar stratosphere at altitudes of 15,000–25,000 meters (49,000–82,000 ft).

All About Aspheric Lenses Spherical Aberration Correction. The most notable benefit of aspheric lenses is their ability to correct for spherical aberration, an optical effect which causes incident light rays to focus at different points when forming an image, creating a blur.

What Is the Asthenosphere? The region directly above the asthenosphere is the lithosphere, the entirely solid uppermost region of the Earth's crust. Earthquakes that occur in the lithosphere are potentially catastrophic because of the severe jarring forces created when two tectonic plates interact.
