Introduction: In recent years, more and people have become infected with Human Immunodeficiency Virus. Of great importance in the course of HIV infection are symptoms diseases, which often occurs oral cavity a corresponding decrease lymphocytes.Aim: The aim study was to present most common diseases patients Virus like hairy leukoplakia, Candidas, angular cheilitis, Linear Gingival Erythema, Her...

The purpose of the present study was to evaluate the prevalence of oral mucosal lesions in Manipal, Karnataka State, India. A total of 1190 subjects who visited the department of oral medicine and radiology for diagnosis of various oral complaints over a period of 3 months were interviewed and clinically examined for oral mucosal lesions. The result showed the presence of one or more mucosal le...

The successful treatment by riboflavin of a number of cases of superficial keratitis was described in two previous papers (Aykroyd and Verma, 1942; Verma, 1942). In the course of this work it was observed that a number of patients with superficial keratitis, associated with angular stomatitis and other signs of riboflavin deficiency, were also suffering from angular conjunctivitis, and that the...

The evolution of polarization and spin angular momentum (SAM) in periodically rocking superlattices (PRS) is investigated. Unlike in the birefringent crystal, they exhibit unusual properties. The evolution of polarization shows many remarkable trajectories and the SAM oscillates inside the PRS. The results may find applications in polarization-state or optical SAM control.

When a left-circularly polarised Gaussian light beam, which has spin angular momentum (SAM) J(sp) = sigmah = 1h per photon, is incident along one of the optic axes of a slab of biaxial crystal it undergoes internal conical diffraction and propagates as a hollow cone of light in the crystal. The emergent beam is a superposition of equal amplitude zero and first order Bessel like beams. The zero ...
