In light microscopy, oil immersion is a technique used to increase the resolving power of a microscope. This is achieved by immersing both the objective lens and the specimen in a transparent oil of high refractive index, thereby increasing the numerical aperture of the objective lens. Without oil, light waves reflect off the slide specimen ...
Meteorological instrumentation. Galileo thermometer. Meteorological instruments (or weather instruments ), including meteorological sensors ( weather sensors ), are the equipment used to find the state of the atmosphere at a given time. Each science has its own unique sets of laboratory equipment. Meteorology, however, is a science which does ...
Differential scanning calorimetry ( DSC) is a thermoanalytical technique in which the difference in the amount of heat required to increase the temperature of a sample and reference is measured as a function of temperature. [ 1] Both the sample and reference are maintained at nearly the same temperature throughout the experiment.
An operating temperature is the allowable temperature range of the local ambient environment at which an electrical or mechanical device operates. The device will operate effectively within a specified temperature range which varies based on the device function and application context, and ranges from the minimum operating temperature to the maximum operating temperature (or peak operating ...
v. t. e. Scanning probe microscopy ( SPM) is a branch of microscopy that forms images of surfaces using a physical probe that scans the specimen. SPM was founded in 1981, with the invention of the scanning tunneling microscope, an instrument for imaging surfaces at the atomic level. The first successful scanning tunneling microscope experiment ...

Streptococcus thermophilus formerly known as Streptococcus salivarius subsp. thermophilus[ 2][ 1] is a gram-positive bacterium, and a fermentative facultative anaerobe, of the viridans group. [ 3] It tests negative for cytochrome, oxidase, and catalase, and positive for alpha-hemolytic activity. [ 3] It is non-motile and does not form ...
Converting units of temperature differences (also referred to as temperature deltas) is not the same as converting absolute temperature values, and different formulae must be used. To convert a delta temperature from degrees Fahrenheit to degrees Celsius, the formula is {ΔT}°F = 9 5 {ΔT}°C. To convert a delta temperature from degrees ...
