However, because water is a polar molecule this process of simple diffusion is relatively slow, and in tissues with high water permeability the majority of water passes through aquaporin. [ 4 ] [ 5 ] The 2003 Nobel Prize in Chemistry was awarded jointly to Peter Agre for the discovery of aquaporins [ 6 ] and Roderick MacKinnon for his work on ...
The concept of wetware is an application of specific interest to the field of computer manufacturing. Moore's law, which states that the number of transistors which can be placed on a silicon chip is doubled roughly every two years, has acted as a goal for the industry for decades, but as the size of computers continues to decrease, the ability to meet this goal has become more difficult ...
The prefix "wet" is a reference to the water found in living creatures. Wetware is used to describe the elements equivalent to hardware and software found in a person, especially the central nervous system (CNS) and the human mind. The term wetware finds use in works of fiction, in scholarly publications [1] and in popularizations. [2]
The first computed tomography (CT) system capable of producing images of any part of the human body without the need for a cumbersome "water tank" was the Automatic Computerized Transverse Axial (ACTA) scanner, designed by Dr. Robert S. Ledley, DDS, at Georgetown University. This revolutionary machine was equipped with 30 photomultiplier tubes ...
The process of osmosis over a semipermeable membrane.The blue dots represent particles driving the osmotic gradient. Osmosis (/ ɒ z ˈ m oʊ s ɪ s /, US also / ɒ s-/) [1] is the spontaneous net movement or diffusion of solvent molecules through a selectively-permeable membrane from a region of high water potential (region of lower solute concentration) to a region of low water potential ...
A human computer, with microscope and calculator, 1952. It was not until the mid-20th century that the word acquired its modern definition; according to the Oxford English Dictionary, the first known use of the word computer was in a different sense, in a 1613 book called The Yong Mans Gleanings by the English writer Richard Brathwait: "I haue [] read the truest computer of Times, and the best ...
The first symptoms of kidney failure are silent. Failing kidneys can’t remove extra fluid from the body, nor can they filter molecules like urea, which can be toxic in high dosages, from the blood.
The interface is primarily used to connect a video source to a display device such as a computer monitor, though it can also be used to transmit audio, USB, and other forms of data. Unline HDMI, DisplayPort is open source. drive bay A standard-sized area within a computer case for adding hardware (hard drives, CD drives, etc.) to a computer.
