Now ELISA Test in Fast Track.

hiv-syphilis-dongle

Just 15 minutes for HIV, Syphilis….

We can now turn any smartphone (whether iPhones or Android devices) into an HIV and syphilis tester. Wonder how? Here is the answer… The plastic attachment, about the size of the phone itself, uses disposable cartridges to load blood and the device’s app reads the results, giving a diagnosis in about 15 minutes. The device, called “dongle”, can be attached to any smart phone or tablet through the audio jack. This is the first low-cost dongle that replicates all mechanical, optical, and electronic functions of a laboratory-based enzyme-linked immunosorbent assay (ELISA) without requiring any stored energy; all necessary power is drawn from a smartphone… This low-weight device is capable of simultaneously detecting HIV antibody, treponemal-specific antibody for syphilis and nontreponemal antibody for active syphilis in a single format….

Bird’s flu

Avian influenza or Bird Flu is a viral infection that can infect not only birds, but also humans and other animals. Most forms of the virus are restricted to birds.

Is bird flu Bird’s flu? Of course, like humans, birds also get flu and is known as “avian influenza”. It is caused by viruses that infect birds and make them ill. It is an infectious disease of birds caused by type A strains of the influenza virus. The virus is spread when wild birds pass the virus along to birds such as chickens or ducks that are being raised for human consumption. While the wild birds do not seem to be affected by the virus, the livestock that contract the virus get very sick and many die.

Avian influenza A viruses are classified into the following two categories: low pathogenic avian influenza (LPAI) A viruses, and highly pathogenic avian influenza (HPAI) A viruses. There are 16 different avian flu types. The H5N1 strain is the one that causes the most concern, because it is the most virulent; the deadliest. Continue reading “Bird’s flu”

Cancer what is it really…………

Cancer cells have an asymmetrically-shaped nucleus that is larger than normal, resulting in the reduced presence of cytoplasm within the cell.

What is It really???

After heart disease, cancer is the most dangerous disease of mankind. Early detection of cancer can greatly improve the odds of successful treatment and survival. Cancer is characterized by out-of-control cell growth. There are over 100 different types of cancer, and each is classified by the type of cell that is initially affected. It harms the body when the cells divide uncontrollably to form masses of tissues called tumors. These cells don’t die, i.e. they don’t follow an orderly path of growth, division and death.

The Art Of Hiding Information ( Steganography )

Steganography Techniques

Steganography serves as a means for private, secure and sometimes malicious communication. Steganography is a technology that hides a message within an object, a text, or a picture. It is often confused with cryptography, not in name but in appearance and usage. The easiest way to differentiate the two is to remember steganography conceals not only the contents of the message but also the mere existence of a message. The original steganographic applications used “null ciphers”, or clear text. A null cipher conveys that the message has not been encrypted in any way,whether it is using basic character shifting, substitution or advanced modern day encryption algorithm. So, the message is often in plain view but for a reason can either not be detected as being present or cannot be seen once detected. As is common with cryptography, steganography has its roots in military and government applications and has advanced in ingenuity and complexity. We will explore several approaches to the process of steganography as well as steganalysis. Steganalysis is the method by which to detect the presence of a hidden message and attempt to reveal the true contents of this message. This technology has also substantially evolved throughout history and often lags behind new steganographic discovery as a reactive attempt to detect and decipher messages.

Hybrid Bike

Electric-Petrol Hybrid” technology

Helloo, everyone out there, I found this news in EFY site . It’s great  if somebody develop this kind of things. It will help future generation to grow well. This wonder bike of 120cc capacity is likely to go on sale in May 2010. Bengaluru-based Eko Vehicles has launched the world’s first hybrid motorcycle called the ET-120. Developed in collaboration with US-based Emerging Vehicle Technologies, the ET-120 model is expected to go on sale in May 2010. The ET-120 is the first hybrid two-wheeler, that comes fitted with an electric motor and a 70cc petrol engine. Continue reading “Hybrid Bike”

Robot-assisted surgery

Robotic- Surgery

Robot-assisted surgery is the latest development in the larger movement of endoscopy, a type of minimally invasive surgery–the idea being that less invasive procedures translate into less trauma and pain for patients. Surgery through smaller incisions typically results in less scarring and faster recovery. It’s not that robots are changing the basics of surgery. Surgeons are still cutting and sewing like they have been for decades. Robots represent a new computer-assisted tool that provides another way for surgeons to work.

THE GPS Technology

GPS Technology

THE GPS Technology

Throughout time people have developed a variety of ways to figure out their position on earth and to navigate from one place to another. Early mariners relied on angular measurements to celestial bodies like sun and stars to calculate their location. The 1920s witnessed the introduction of more advanced technique-radio navigation-based at first on radios that allowed navigators to locate the direction of shore-based transmitters when in range. Later development of artificial satellites made possible the transmission of more precise, line of sight radio navigation signals and sparked a new era in navigation technology. Satellites are first used in position finding in a simple but reliable 2D Navy system called Transit. This laid the groundwork for a system that would later revolutionize navigation for ever-the Global Positioning System.. Continue reading “THE GPS Technology”
