This project is a reference to budding engineers or a helping hand to those who willing to work and interface a GPS Receiver with microcontrollerand making their own channel to communicate with satellite, seeking for some useful information from satellite to make a effective and efficient system. Before we check all the details of this […]

This tutorial will give you a brief introduction to the concept of colors and how different colors can be produced using RGB LED. The color would be controlled using an ATMega16 microcontroller. RGB LEDs are basically the combination of the 3 LEDs (Red, Green and Blue) fused into a single package. It consists of four […]

The toxic dinoflagellate, Alexandrium fundyense, is a photosynthetic plankton—a microscopic organism floating in the ocean, unable to swim against a current. New research by scientists at the University of Hawai’i at Manoa (UHM) School of Ocean and Earth Science and Technology (SOEST) suggests that ingestion of this dinoflagellate changes the energy balance and reproductive potential of a particular copepod—a small crustacean—in the North Atlantic, which is key food source for young fishes, including many commercially important species.

Being at the top of the food chain is no guarantee of a species survival. Not only are many of these so-called apex predators susceptible to human impacts, they also are slow to recover from them, which makes these animals vulnerable despite their high-ranking ecosystem status.

A U of T Engineering team has designed a simpler way to keep therapeutic proteins where they are needed for long periods of time. The discovery is a potential game-changer for the treatment of chronic illnesses or injuries that often require multiple injections or daily pills.

With climate change already close to an irreversible tipping point, urgent action is needed to reduce not only our mean (carbon) footprints but also the “number of feet” – that is, the growing population either already creating large footprints or aspiring to do so, argues a leading physician and environmentalist in The BMJ today.

An expansive bed of underwater grass at the mouth of the Susquehanna River has proven it is able to “take a licking and keep on ticking.” A recent study has found that the submersed aquatic vegetation (SAV) bed at Susquehanna Flats, which only recently made a comeback in the Chesapeake Bay, was not only able to survive a barrage of rough storms and flooding, but it has proven a natural ability to protect and maintain itself.

Stepper motor can be termed as digital motor because it operates on pulses. Unlike AC or DC motor that rotates continuously, stepper motor rotates in steps. It rotates in number of steps as per applied number of pulses. Stepper motor is used in many applications like: . Robotic application – to move robotic arm to […]

In many application of controlling robotic gadget it  becomes quite hard and complicated when there comes the part of controlling it with remote or many different switches. Mostly in military application, industrial robotics, construction vehicles in civil side, medical application for surgery. In this field it is quite complicated to control the robot or particular […]

The view that the rich are highly mobile has gained much political traction in recent years and has become a central argument in debates about whether there should be “millionaire taxes” on top-income earners. But a new study dispels the common myth about the propensity of millionaires in the United States to move from high to low tax states.
