In this type of movement the snake moves in the form of a sinusoidal wave. Secondly, Concertina or accordion locomotion. In this type of movement the body of the snake contracts and expands successively like an accordion or a spring. Thirdly, Lateral displacement or sidewinding locomotion. In this type of movement the snake moves laterally by forming vertical waves. In this way it minimizes contact with the surface. This type of movement is typical of snake species found in desert areas. Fourthly, Rectilinear locomotion. In this type of movement the snake crawls in a straight line with its body stretched. This type of movement is commonly found among larger snakes as it allows them to access narrow burrows of their potential prey.

Buy AumSum Merchandise: https://www.aumsum.com How does a Pulse Oximeter Work? Pulse Oximetry is a test carried out using a Pulse Oximeter. This test is used to measure the oxygen level in our blood. Pulse Oximetry is based on the principle that Oxygenated Hemoglobin and Deoxygenated Hemoglobin differentially absorb red and infrared light. Hemoglobin is a protein present inside our red blood cells, it transports oxygen from lungs to cells in our body. Oxygenated Hemoglobin absorbs greater amounts of infrared light and lower amounts of red light as compared to Deoxygenated Hemoglobin. Now, a Pulse Oximeter has LEDs which emit red as well as infrared light. These lights pass through our finger and are detected by a photodiode on the opposite side. Finally, by measuring changes in the light absorption a Pulse Oximeter is able to give us the Oxygen level in our blood.

Buy AumSum Merchandise: https://www.aumsum.com How do Hurricanes Form? Hurricanes form only over warm ocean waters near the equator. This warm water evaporates resulting in the formation of warm, moist over the ocean surface. This air rises up, creating an area of low air pressure below. Air from surrounding areas pushes into this low pressure area. This air also becomes warm and moist and rises. This cycle keeps on continuing. Now as the warm, moist air keeps on rising it cools off and forms clouds. Even big, stormy, cumulonimbus clouds are formed. Now as the warm air continues to rise upward, winds start blowing in a circular pattern around the center. Once these winds reach a speed of 74 miles per hour the storm is officially classified as a Hurricane.

Buy AumSum Merchandise: https://www.aumsum.com How does a 3D Printer Work? A 3D printer uses a method called fused deposition modeling. In this method a 3D model is printed from the bottom up, one layer at a time by repeatedly printing over the same area. First, a 3D CAD drawing is fed to the printer. The 3D printer divides the 3D drawing into 2 dimensional, cross-sectional layers. These layers are basically like separate 2D prints which sit on the top of one another. The only difference is that there is no paper in between. Now if we were to use ink to print then it would not be possible to get the volume necessary to build a 3D model, hence instead of ink the 3D printer may use molten plastic. The molten plastic is fused together using an adhesive or ultraviolet light.

How do Portable Oxygen Concentrators Work? In simple terms, an Oxygen Concentrator takes in air and removes nitrogen from it. Our air is 78% nitrogen and 21% oxygen. Removal of nitrogen leaves an oxygen-enriched gas. This gas can be used by people requiring medical oxygen. Oxygen concentrator consists of an air compressor. It takes in air from the atmosphere, compresses it and passes it over porous zeolite minerals. Zeolite adsorbs large quantity of nitrogen from air because of its large surface area and chemical characteristics. The remaining oxygen-rich gas is used for medicinal purposes while the nitrogen is desorbed from zeolite under reduced pressure and vented out. In Portable Oxygen Concentrators as high purity is not essential and feed gas can be discarded, size of the adsorbent bed is reduced and Rapid pressure swing adsorption or RPSA is frequently used.

How do Electromagnets Work? The construction of an electromagnet is very simple. A conductive wire, usually made of copper is wrapped around a piece of metal, in this case iron. Now with the help of a battery a current is introduced. This current starts flowing through the coiled wire, resulting in the creation of a magnetic field. This magnetic field magnetizes the iron metal. Thus resulting in the creation of an electromagnet. An electromagnet is similar to a magnet, it has two poles, like poles repel each other while opposites attract. Also it is able to attract iron filings. The only difference is that the magnetism is not permanent, once the current is removed, magnetism may stop working suddenly or after some time. An electric bell is a good example of the use of an electromagnet.

Buy AumSum Merchandise: https://www.aumsum.com Why do we have Leap Years? By definition, A leap year is a calendar year that contains an additional day added to keep the calendar year synchronized with the astronomical year. Our year consists of 365 days. A year is the amount of time it takes a planet to orbit its star one time. It takes Earth approximately 365 days and 6 hours to orbit the Sun. So there is a difference of 6 hours between our calendar year and solar year. Now, those 6 hours just can t disappear, right? In order to make sure that our calendar year matches the solar year, after every 4 years, we add those 6 hours 4 times, i.e. 1 day is added to a year. Thus, this year has 29 days in February instead of 28. This is why we have Leap Years.

Buy AumSum Merchandise: https://www.aumsum.com How do Electron Microscopes (Scanning) Work? Scanning Electron Microscopes are used to produce very sharp, 3D images by scanning the surface of extremely tiny objects. A Scanning Electron Microscope consists of an electron gun. Once the object to be scanned is placed, this gun is used to shoot a focused electron beam at it. Scanning Electron Microscope consists of a series of electromagnetic coils. These coils can pull the electron beam back as well as forth. They systematically scan the entire surface of the object. This electron beam does not pass through the object, rather it is reflected off its surface. These reflected electrons or secondary electrons are directed at a Cathode-ray TV Screen. The image of the scanned object is formed on this screen. This is how a Scanning Electron Microscope works.
