don't know who, but it was invented in 1955.
The weight of a diaphragm can vary depending on the specific material and design. On average, a diaphragm can weigh anywhere from a few grams to a couple of ounces.
The diaphragm on a microscope controls the amount of light that passes through the specimen. By adjusting the diaphragm, you can control the contrast and brightness of the image being viewed.
The diaphragm in a microscope controls the amount of light that passes through the specimen. By adjusting the diaphragm, you can regulate the brightness and contrast of the image, allowing for clearer observations.
The diaphragm is connected to circulation through the phrenic nerves, which control the contractions of the diaphragm muscle. When the diaphragm contracts during inhalation, it creates a negative pressure in the chest cavity, allowing the lungs to expand and draw in air, which helps with oxygenation of the blood.
The diaphragm on a microscope is there so one can adjust the amount and intensity of light that gets projected up into the slide. The diaphragm is a rotating disk located under the stage. Not all microscopes have one.
the diaphragm valve was developed during the 1940s.
The iris diaphragm was invented by Joseph Petzval, a Hungarian mathematician, and physicist, in the mid-19th century. Petzval's invention of the iris diaphragm revolutionized photography by allowing photographers to control the amount of light entering the camera lens, leading to better image quality and exposure control.
Robert Hooke invented the iris diaphragm in the 17th century, specifically around the year 1665. This invention was part of his work on the microscope, which he detailed in his book "Micrographia." The iris diaphragm improved the control of light entering the microscope, enhancing the visibility of specimens.
it is called the diaphram.
The diaphragm is not made out of bone, but the diaphragm is a muscle.
The muscle you are referring to is the diaphragm. It also separates the thoracic cavity from the abdominopelvic cavity.
the diaphragm is the muscle separating the chest and the abdomen
what is diaphragm cancer
Your diaphragm contracts and expands when you breath. When the diaphragm contracts, air rushes into the lungs. When the diaphragm relaxes, air is exhaled.
In 1974, Henry Heimlich first described the Heimlich maneuver (HIM'lik mah-NOO'ver), which are a series of under-the-diaphragm abdominal thrusts.For more information see:abdominal-thrusts
When you breathe in, your diaphragm contracts. This makes the diaphragm move lower and increases the area in your lungs.
