      How a Nuclear Heart Scan Works

      A nuclear heart scan is an excellent method to evaluate the health of your heart. Nuclear heart scans are safe and extremely effective for diagnosing specific kinds of heart conditions. The process of having a nuclear scan is relatively simple and in most cases is painless. During a nuclear heart scan, a radioactive tracer (which

    • Transmission Electron Microscope

      Transmission Electron Microscope

      The transmission electron microscope (TEM) is a scientific instrument that uses electrons instead of light to scrutinize objects at very fine resolutions. They were developed in the 1930s when scientists realized that electrons can be used instead of light to "magnify" objects or specimens under study. TEMs provided a means to go beyond the magnification

    • What is Magnetic Wire?

      What is Magnetic Wire?

      Magnetic wire is a copper or aluminum wire that produces an electromagnetic field when wrapped into a coil and connected to a power supply. It is used in a number of applications and is a vital component in many different devices. Magnetic wire can be used in electrical to electrical, electrical to mechanical, and mechanical

    • Ultrasonic Humidifier

      Ultrasonic Humidifier

      An ultrasonic humidifier is a device that uses ultrasonic sound waves to create water droplets from a built-in water reservoir. Ultrasonic humidifiers are used in many homes, businesses, and warehouses to properly humidify an area without using heat. Because ultrasonic humidifiers do not use heat, they use much less electricity (approximately 93% less) than other

    • Torsional Vibration

      Torsional Vibration

      Solid mechanics defines torsion as the twisting of an object as a result of applied torque. Torsional vibration can be broadly described as the angular vibration of any object. It can be defined specifically as the periodic motion corresponding to a shaft, where the shaft is twisted about its axis, alternating from one direction to

    • How Do Ocean Currents Affect Climate?

      How Do Ocean Currents Affect Climate?

      Ocean currents are one of the main factors that affect climate. Other factors are proximity from the equator, distance from the sea, direction of prevailing winds and relief (mountains). But, for the most part, ocean currents act as one of the most important factors that influence the climate. And the reason why is because a

    • Air Circulators

      Air Circulators

      An air circulator is basically a fan. Although the term “air circulator” most often refers to an industrial fan that is used in a warehouse, factory, or office building, it can also refer to a regular household fan. Air circulators also refer to air conditioning units and other types of air cooling devices. They are

    • Radiometric Dating

      Radiometric Dating

      Radiometric dating is a process of identifying the age of a material based on known half-lives of decaying radioactive materials found in both organic and inorganic objects. Radiometric dating is often used to determine the age of rocks, bones, and ancient artifacts. In fact, radiometric dating can be used to determine the age of the

    • How Do Oil Booms Work?

      How Do Oil Booms Work?

      Oil spills can occur with little to no notice. When a spill does happen, it becomes critical to act quickly to contain the spill in order to mitigate damage to the environment. Oil booms are commonly used in maritime environments as both a reactive action to a spill or as a preventative measure around ships

    • Vibration Isolators

      Vibration Isolators

      There are a number of vibration sources throughout the world. In most cases, these movements have undesirable effects on things used in daily life, such as buildings and vehicles. Vibration isolators reduce or eliminate the effects of vibrations on equipment and structures. These devices are commonly referred to as shock mounts, snubbers, machine mounts, and
