Stomata are a special type of pore opening on leaves of plants. They are designed to absorb water from sources such as rain while also removing excess water in the plant through transpiration. The way that the stomata work is still a mystery as we truly do not understand what causes their functioning and how. The Role …
In the last several decades, medical technology has advanced in leaps and bounds. One of the most advanced technological instruments used in medicine today is the nuclear bone scan. A nuclear bone scan uses a radioactive tracer and high-resolution camera to identify areas of new bone growth or areas in which bone has broken down. …
Magnetic propulsion is the act of moving an object with magnetic fields and a flowing electrical current. The current is used to manipulate the system’s magnetic field or charge a fluid in the system that can be repelled. The Lorentz force then pushes the conductor in a direction that is perpendicular to the magnetic field …
Pharming is a process whereby plants and animals are genetically modified to become carriers of genes that stimulate the production of substances that have useful pharmaceutical applications. Thus, the term pharming is actually a play on the words pharmaceuticals and farming. To explain the process in simple terms, a foreign gene is introduced into the …
Transconductance is a property of some electronic components and is also known as mutual conductance. It is the opposite of resistance. The measure of transconductance is the ratio of the electrical current change at an output port as compared to the voltage change at the input port. The measure of transconductance is commonly used in …
MagLev Trains are trains that rely on magnets or magnetic force to run. There are different kinds of MagLev Trains that have been developed and they differ on the technology used to attract the magnetic force or magnets to make the train run or levitate. Each project is developing its own version of Magnetic levitation …
In the field of spectroscopy, fluorescence can be analyzed from a sample of material through a special form of electromagnetic spectroscopy. This fluorescence spectroscopy uses a beam of light that is tailored for the type of fluorescence detection needed in compounds. The usual option is an ultraviolet light that is used to excite electrons in …
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 …
Lemon juice has a natural pH of 2.0 and is naturally acidic. When mixed with vitamins and other additives in the lemon juice normally found in stores for human consumption, the pH is slightly less acidic with a pH measure of between 2.2 and 3.0. Due to the natural acidicy of lemon juice, it can …
One of the most prominent gauges on an automobile’s dashboard is the speedometer. Its primary function is to give a visual indication of a vehicle’s speed in miles or kilometers (or both) per hour. Since the majority of these devices are still analog, they may require speedometer calibration when new tires are installed, major automotive …
