Design is the creation of a plan or convention for the construction of an object, system or measurable human interaction (as in architectural blueprints, engineering drawings, business processes, circuit diagrams, and sewing patterns). Design has different connotations in different fields (see design disciplines below). In some cases, the direct construction of an object (as in pottery, engineering, management, coding, and graphic design) is also considered to use design thinking.
A neutrino is a subatomic particle that is very similar to an electron, but has no electrical charge and a very small mass, which might even be zero.Neutrinos are one of the most abundant particles in the universe. Because they have very little interaction with matter, however, they are incredibly difficult to detect.n particle interactions, although electrons and electron-neutrinos can be created and destroyed, the sum of the number of electrons and electron-neutrinos is conserved. This fact leads to dividing the leptons into three families, each with a charged lepton and its accompanying neutrino.
Neutropenia (noo-troe-PEE-nee-uh) is an abnormally low level of neutrophils. Neutrophils are a common type of white blood cell important to fighting off infections â particularly those caused by bacteria. For adults, counts of less than 1,500 neutrophils per microliter of blood are considered to be neutropenia. For children, the cell count indicating neutropenia varies with age. Some people have lower-than-average neutrophil counts, but not an increased risk of infection.
