The human eye can be classified into two segments: anterior and posterior segments. The cornea, conjunctiva, iris, ciliary body, aqueous humor and lens are includes in the anterior segment and sclera, choroid, retina, vitreous humor are includes in the posterior segment. The outermost transparent membrane of the eye is cornea such are the corneal epithelium, bowman's membrane, stroma, descemet's membrane, and endothelium. The anterior segment is a fluid of the eye which contains the source of nutrition
Introduction Plastics is of the most uses material around the world. The term plastic is used for several materials of a synthetic or semi-synthetic nature. The term plastic came from the Greek word plastikos, this word means “fit for molding.” Plastics have many different properties when observed as a total. This what make plastic has many uses such as, rubber, cellulose, asphalt, and shellac. Also, it can be manufacture items like, electronics, clothing aircraft, packaging, recreational items
is the one with certain types of characteristics, material and properties. Basketball is basically a game played in a rectangular court by two teams intending to throw the ball into the hoop on the backboard. The game requires a constant handling of ball from one player to another. The basketball ball has to be designed in such a way to make the game easy to be played. The basket ball is an inflated spherical
membrane preparation involves a two step process. In the first step the prepared polymer film is irradiated with high energy particles which are generated by nuclear reactor or by any other radiation source. The high energy particles used in this technique includes α- particles, accelerated heavy ions, fission fragments and thermal neutrons. These high energy particles pierce through the polymer film breaking polymer chains and leaving behind sensitized or damaged tracks. The second step involves
And it is also a major synthetic material for textile as well as composite industry. A important quality of PP is its capability that it is used in wide fibrous forms. Various applications like automobiles, medical as well as geo textiles are summarized [1]. Creep resistance is
Self-healing materials are no more an illusion and we are not far away from the days when manmade materials can restore their structural integrity in case of a failure. For example, the cracks in buildings can close on their own or the scratches on car bodies can recover their original shiny appearance by itself. Indeed, this is what everyone can see in case of the natural healing of wounds and cuts in living species. In the case of structural materials the long-time degradation process leads to
is a copolymer which forms bonds between soil or aggregate particles and is used as a soil stabilizer and dust control agent. Gorilla Snot® is a biodegradable product and environmentally safe to use (www.soilworks.com). Durasoil® is ultra-pure, synthetic organic fluid which is distinctively crystal clear, odorless and is applied neat and simple without dilution in water. Any equipment capable of spraying water can be safely used to apply Gorilla Snot® without any damage to the equipment, even in
Chemical reduction method is a general method that many researchers used to obtain AgNP. These reactions are carried out in solution and the product has colloidal characteristics. The common phenomenon that occurs in these reactions is co-precipitation. The step of these reactions involves reduction, nucleation, growth, and/or agglomeration of the particle [44]. The most important aspect of chemical reduction method is the value of the standard reduction potential (E0). This means that the free energy
Objective: In the present study, an attempt was made to improve the bioavailability of Zidovudine by formulating into Orodispersible tablets, as it has poor bioavailability and extensive pre systemic metabolism. Methods: In the present study, the mucilage extracted from Fenugreek seeds (Trigonella foenum-graecum) was used as superdisintegrant. The oral dispersible tablets were prepared by using wet granulation technique. A three factor two level (23) central composite design was employed for the
new area in chemical engineering termed process intensification. Process intensification (explaination). Its first goal is to build smaller, more compact, and cheaper production plants. It breaks the ceilings of conventional technology and boost synthetic chemistry on both lab and industry scale. Factors to be intensified includes temperature, pressure, reactant concentration, residence time and explosive conditions. One way to realize these intensified conditions is by miniaturize the existing units
