Circuit In electronics, a circuit is a path between two or more points along which an electrical current can be carried. (A   circuit breaker   is a device that interrupts the path when necessary to protect other devices attached to the circuit - for example, in case of a power surge.) A   virtual circuit , sometimes called a   logical circuit , is a path between two or more points that seems like a fixed physical path, but actually is one path out of many possible physical paths that can be arranged. A permanent virtual circuit( PVC ) is a virtual circuit that provides a guaranteed connection between two or more points when needed without having to reserve or commit to a specific physical path in advance. This allows many companies to share a common pool of circuits. This approach is used in a   frame relay   network and offers a committed set of resources to a telephone company customer at a lower price than if the customer leases their own circui...

Pharamcovigilance Pharmacovigilance   the science related to detection , assessment , understanding and prevention of adverse effect , particularly long term and short term side effect of medicines. Generally speaking, Pharmacovigilance is the collecting, monitoring, searching and evaluating information from healthcare providers and patients on the adverse effect of medication, biological products, herbalism and traditional medicines with a view to: 1)      Identified new information about hazards associated with medicines 2)      Preventing harm to patients The etymological routes are: pharmacon (Greek), “Drugs” , and Vigilare (Latin), “to keep away or alert, to keep watch” . Pharmacovigilance is particular is concerned with adverse drug reaction, or ADRs, which are prescribed as: “A response to a drug which is noxious and unintended, and which occurs at doses normally used for the prophylaxis, diagnosis or therapy ...

Bionic Eye & Lanes Introduction Bionic eye is a bio-electronic eye. Bionic eye replaces the functionality of a part or whole of the eye. An external camera is worn on a pair of dark glasses which sends the images in digital form to the radio receiver placed in the eye. The radio receiver is attached to the implant chip on the retina. The implantation is of two types, epiretinal implant and subretinal implant, based on whether the implant is placed on or behind the retina. In our proposed method of bionic eye, a small and a powerful camera powered by nanogenerator, is implanted inside the patient’s eye rather than worn on a pair of glasses. The camera is small and consumes very low power. *The Human eye Structure and function The Human eyes operate on the same principle as that of a camera. The Human eye is an organ that reacts to light for several purposes. The Human eye ball is roughly spherical in shape. The important part of the eye responsible for the vision is th...

New antibiotic in 30 years discovered in major breakthrough(Texiobactin) Introduction The first new antibiotic to be discovered in nearly 30 years has been hailed as a ‘paradigm shift’ in the fight against the growing resistance to drugs. teixobactin  has been discovered by scientists who claim it appears to be as good, or even better, than many existing drugs with the potential to work against a broad range of fatal infections such as pneumonia and tuberculosis. Teixobactin has been found to treat many common bacterial infections such as tuberculosis, septicaemia and C. diff, and could be available within five years. But more importantly it could pave the way for a new generation of antibiotics because of the way it was discovered. Chemical Structure Scientists have always believed that the soil was teeming with new and potent antibiotics because bacteria have developed novel ways to fight off other microbes. Laboratory tests have shown the new antibiot...

*INTRODUCTION Wheat grass can be traced back in history over 5000 years, to ancient Egypt and perhaps even  early Mesopotamian civilizations. It is purported that ancient Egyptians found sacred the young  leafy blades of wheat and prized them for their positive effect on their health and vitality. The  consumption of wheatgrass in the Western world began in the 1930s as a result of experiments  conducted by Charles F. Schnabel in his attempts to popularize the plant1. By 1940, cans of  Schnabel's powdered grass were on sale in major drug stores throughout the United States and  Canada [1] . Throughout human history, plants have played a key role in treating human diseases. In thousands of years of trials, human found many plants which are good for treating ailments and  curing serious health problems like cancer, diabetes, and atherosclerosis. They are a kind of alternative medicine that is inexpensive, and has no side effects. For example: whea...
