Laser Based Communication System. Introduction:- An optical communication system for inter and intra building communications can be built using the following three basic component. A light emitting element. 1. A light emitting element‚ which could be a laser diode or light emitting diode. 2. Transmission media such as optical fiber cable or free space. 3. A light receiving element‚ which could employ avalanche photo-diode‚ PIN photo-diode or any other light sensors like LDR. Since the

Metals and Halogens reactions Elements such as fluorine‚ chlorine‚ bromine‚ iodine‚ and astatine belong to Group 7‚ Halogens. At room temperature‚ fluorine is a yellow gas‚ chlorine is a pale green gas‚ bromine is a red liquid‚ and iodine is a purple solid. Astatine is a radioactive element‚ therefore it exists only in small amounts. All the halogens exist in diatomic molecules. They have high ionization energies and are the most electronegative elements. Their electron configuration ns2 np5 make

KINETIC STUDY OF LIQUID-PHASE ADSORPTIVE REMOVAL OF HEAVY METAL IONS BY ALMOND TREE (TERMINALIA CATAPPA L.) LEAVES WASTE ABSTRACT. The kinetic sorption of five metal ions - Al3+‚ Cr6*‚ Zn2+‚ Ag+ and Mn2+ - from aqueous solution onto almond tree leaves (ATL) waste in single component system has been studied. The experimental data was analyzed in terms of intraparticle diffusion and rate of adsorption‚ thus comparing transport mechanism and chemical sorption processes. The sorption rates based on

separate eyes creating two separate images‚ while the ability to adapt to light change is attributed to the iris and the dilator muscles. However these two aspects of the eye are not involved in laser eye surgery and will not be discussed in reference. The focusing of objects and images is very much part of laser eye surgery. In order for a clear visual image to be formed the image must come to a point on the retina. Light rays do not normally travel toward each other‚ usually the light rays either travel
