The retina is a very sensitive inner coat of the eye. It consists of ten layers, which are inner limiting membrane, nerve fiber layer, Ganglion cells layer, inner plexiform layer, inner nuclear layer, outer plexiform layer, outer nuclear layer, external limiting membrane, photoreceptors (rods and cones) and retinal pigment epithelium. Also, it has a yellow spot, called macula, which is the important area for high acuity vision. In the retina, the light rays are converted into electrical signals…
generated based on the nonlinear propagation of the multi-cycle laser pulses, carried at central wavelength ~790nm, and τFWHM pulse duration is ~ 22 fs (in intensity) at 1mJ., in a gas filled hollow core fiber (HCF). Hence, these pulses are focused by a bi-convex lens (f=1.8 m) into the hollow core fiber entrance. The beam size at the focus is ~ 200 µm. The converging beam enters the HCF apparatus chamber, which is schematically illustrated in Figure 3a, through a ~0.5mm fused silica…
light has slightly shorter wavelengths than millimeters light, whose wavelengths are measured in millimeters). These ranges fall along the boundary between bands for radio and microwave electromagnetic spectrum, and have longer wavelengths than optical light. This band of light allows astronomers to probe the dark cores of gas clouds to study the formation of stars and planet, and see a very distant light that was shifted to the red end of the spectrum. The electronic detector is called "front…
The edible jackfruit is created of easily absorbable flesh (bulbs); a 100-g part of eatable raw jackfruit produce a great amount of the antioxidant vitamin C, contributing about 13.7 mg (Umesh Rudrappa, 2016). The ripe jackfruit pulp consumes in fresh state and eaten in fruit salads. Jackfruit is relatively small in calories and fat and a great source of Vitamin A (Crane et al., 2005) The jackfruit consists of ellagic acid, free sugar (sucrose), fatty acids, and amino acids like arginine,…
the anatomical association of AGRP or α-MSH containing fibers and MC3R-expressing neurons. Although CTB is a well established retrograde tracer 11,118-120, it has also been used for anterograde labeling121. However, we do not expect anterograte transport to interfere with the ability to identify retrogradively labeled neurons because the signal produced by anterograde labeling is weak and requires IHC amplification121,122. CTB uptake by fibers of passage or damaged axons has been reported to be…
started being used in homes, creating broadband services. This cable has an inner conductor surrounded by a tubular insulating layer, surrounded by a tubular conducting shield. Optical: This is a cable which has a number of optical fibers connected together, these are normally covered in their own protective plastic covers. Optical cables are used for transferring digital and data…
1.1 anatomy of the cornea 1.1.1 Anatomy of the Cornea The cornea is important visual part of the eye, it’s a thin dome-shaped oval from the front and circular from behind and covers the front part of the eye which include iris, pupil and anterior chamber. It forms anterior 1\6 of the outer coat of the globe.[1] The sclera and the conjunctiva overlap the cornea more vertically than horizontally. Together with the lens, the cornea refract light, and it is approximately 43 diopters of the total…
" It has been adopted by all 50 states, though variations may exist on the state and city level. IT is designed to cover the installation of all electrical devices in your home, including: Electrical conductors Raceways Wiring Optical fiber cables Communication…
QUESTION: Give the Preparation, Properties and Applications of any four POLYMERS 1. Polyethenics ( Vinyl Resins) They are obtained by the polymerization of monomers containing the ethylenic bond (-C=C-) I. Polyethylene ( PE ) Polyethylene is one of the simplest and most inexpensive polymers. It is a waxy, chemical inert plastic. It a thermoplastic formed by the addition polymerization of ethylene. There are two types of polyethylene Low Density polyethylene (LDPE) By using free radical…
Trace Evidence: Hair & Fibers Analysis Trace Evidence Defined as materials that could be transferred during the commission of a violent crime, trace evidence consists of multiple sources of which include hair, fibers, soil, gunshot residue, among many more. Trace evidence can be transferred between people, objects, or the environment during the commission of a crime (Federal Bureau of Investigation, 2016). This idea is known as the Locard exchange principle which is the idea that whenever…
