Travoprost. Travoprost, sold under the brand name Travatan among others, is a medication used to treat high pressure inside the eye including glaucoma. [4] Specifically it is used for open angle glaucoma when other agents are not sufficient. [5] [4] It is used as an eye drop. [4] Effects generally occur within two hours.
A 1951 USAF resolution test chart is a microscopic optical resolution test device originally defined by the U.S. Air Force MIL-STD-150A standard of 1951. The design provides numerous small target shapes exhibiting a stepped assortment of precise spatial frequency specimens. It is widely used in optical engineering laboratory work to analyze and ...
Table of nuclides. A table or chart of nuclides is a two-dimensional graph of isotopes of the elements, in which one axis represents the number of neutrons (symbol N) and the other represents the number of protons (atomic number, symbol Z) in the atomic nucleus. Each point plotted on the graph thus represents a nuclide of a known or ...
As of 2020, the most expensive non- synthetic element by both mass and volume is rhodium. It is followed by caesium, iridium and palladium by mass and iridium, gold and platinum by volume. Carbon in the form of diamond can be more expensive than rhodium. Per-kilogram prices of some synthetic radioisotopes range to trillions of dollars.
UnitedHealth says files with personal information that could cover a “substantial portion of people in America” may have been taken in the cyberattack earlier this year on its Change ...
Chemical structure of the prototypical Z-drug zolpidem. Nonbenzodiazepines (/ ˌ n ɒ n ˌ b ɛ n z oʊ d aɪ ˈ æ z ɪ p iː n,-ˈ eɪ-/), sometimes referred to colloquially as Z-drugs (as many of their names begin with the letter "z"), are a class of psychoactive; depressant, sedative, hypnotic, anxiolytic drugs that are benzodiazepine-like in uses, such as for treating insomnia and anxiety.
5639-0, 5640-8, 15120-9, 56478-1. Blood alcohol content ( BAC ), also called blood alcohol concentration or blood alcohol level, is a measurement of alcohol intoxication used for legal or medical purposes. [1] BAC is expressed as mass of alcohol per volume of blood. In the US and many international publications, BAC levels are written as a ...
The concept of the valley of stability is a way of organizing all of the nuclides according to binding energy as a function of neutron and proton numbers. [1] Most stable nuclides have roughly equal numbers of protons and neutrons, so the line for which Z = N forms a rough initial line defining stable nuclides.
