Virus crystallisation is the re-arrangement of viral components into solid crystal particles. [1] The crystals are composed of thousands of inactive forms of a particular virus arranged in the shape of a prism. [2] The inactive nature of virus crystals provide advantages for immunologists to effectively analyze the structure and function behind ...
System: Eye and visual system: Significant diseases: Cataract, retinal disease (including diabetic retinopathy and other types of retinopathy), glaucoma, corneal disease, eyelid and orbital disorders, uveitis, strabismus and disorders of the ocular muscles, ocular neoplasms (malignancies, or cancers, and benign eye tumors), neuro-ophthalmologic disorders (including disorders of the optic nerve)
In particular, owl's eye appearance has been used to indicate the presence of cytomegalovirus (CMV), a genus of virus found in humans and other primates. The description "owl's eye" may refer to: Cells with perinuclear vacuolization around centrally located pyknotic nuclei, such as typically seen in flat warts .
Infective conjunctivitis is most commonly caused by a virus. [3] Bacterial infections, allergies, other irritants, and dryness are also common causes. Both bacterial and viral infections are contagious, passing from person to person or spread through contaminated objects or water. Contact with contaminated fingers is a common cause of ...
The detection of optical scattering and the gradient forces on micron sized particles was first reported in 1970 by Arthur Ashkin, a scientist working at Bell Labs. [1] ...
Polarization mode dispersion (PMD) is a form of modal dispersion where two different polarizations of light in a waveguide, which normally travel at the same speed, travel at different speeds due to random imperfections and asymmetries, causing random spreading of optical pulses.
Rough plot of Earth's atmospheric transmittance (or opacity) to various wavelengths of electromagnetic radiation, including visible light.. The optical window is the portion of the optical spectrum that is not blocked by the Earth's atmosphere.
