Open-high-low-close chart – OHLC charts, also known as bar charts, plot the span between the high and low prices of a trading period as a vertical line segment at the trading time, and the open and close prices with horizontal tick marks on the range line, usually a tick to the left for the open price and a tick to the right for the closing ...
The radar antenna sends pulses while rotating 360 degrees around the radar site at a fixed elevation angle. It can then change angle or repeat at the same angle according to the need. Return echoes from targets are received by the antenna and processed by the receiver and the most direct display of those data is the PPI.
Barometer A device for measuring pressure. Battery Electrochemical cells that transform chemical energy into electricity. Base In chemistry, bases are substances that, in aqueous solution, release hydroxide (OH −) ions, are slippery to the touch, can taste bitter if an alkali, [50] change the color of indicators (e.g., turn red litmus paper blue), react with acids to form salts, promote ...
The Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES) is an intergovernmental organization established to improve the interface between science and policy on issues of biodiversity and ecosystem services. [46] [47] It is intended to serve a similar role to the Intergovernmental Panel on Climate Change. [48]
A flat coating does not directly increase the size of the light cone in the semiconductor; it provides an intermediate wider cone angle in the coating, but the critical angle between rays in the semiconductor and in the air beyond the coating does not change. With a curved coating or encapsulation, however, efficiency can be further increased.
A course deviation indicator (CDI) [1] is an avionics instrument used in aircraft navigation to determine an aircraft's lateral position in relation to a course to or from a radio navigation beacon. If the location of the aircraft is to the left of this course, the needle deflects to the right, and vice versa.
Air pollutants vary in potency, and the function used to convert from air pollutant concentration to AQI varies by pollutant. Its air quality index values are typically grouped into ranges. Each range is assigned a descriptor, a color code, and a standardized public health advisory. The AQI can increase due to an increase of air emissions.
Hence, a pH indicator is a chemical detector for hydronium ions (H 3 O +) or hydrogen ions (H +) in the Arrhenius model. Normally, the indicator causes the color of the solution to change depending on the pH. Indicators can also show change in other physical properties; for example, olfactory indicators show change in their odor.
