The prism fusion range ( PFR) or fusional vergence amplitude is a clinical eye test performed by orthoptists, optometrists, and ophthalmologists to assess motor fusion, specifically the extent to which a patient can maintain binocular single vision ( BSV) in the presence of increasing vergence demands. Motor fusion is largely accounted to ...
The prism cover test ( PCT) is an objective measurement and the gold standard in measuring strabismus, i.e. ocular misalignment, or a deviation of the eye. [1] It is used by ophthalmologists and orthoptists in order to measure the vertical and horizontal deviation and includes both manifest and latent components. [1]
The mass density of a gas can be measured by using a gas collecting tube, an analytical balance and an aspirator. The mass and volume of a displaced amount of gas are determined: At atmospheric pressure p {\displaystyle p} , the gas collecting tube is filled with the gas to be investigated and the overall mass m f u l l {\displaystyle m_{full ...
A gas-filled tube, also commonly known as a discharge tube or formerly as a Plücker tube, is an arrangement of electrodes in a gas within an insulating, temperature-resistant envelope. Gas-filled tubes exploit phenomena related to electric discharge in gases , and operate by ionizing the gas with an applied voltage sufficient to cause ...
Base excess is defined as the amount of strong acid that must be added to each liter of fully oxygenated blood to return the pH to 7.40 at a temperature of 37°C and a pCO 2 of 40 mmHg (5.3 kPa). [2] A base deficit (i.e., a negative base excess) can be correspondingly defined by the amount of strong base that must be added.
June 26, 2024 at 5:28 PM. MINNEAPOLIS (AP) — Five people were charged Wednesday with conspiring to bribe a Minnesota juror with a bag of $120,000 in cash in exchange for the acquittal of ...
A trust fund that gets money from a gas tax helps — it currently holds about $1.5 billion — but the program costs states and the federal government about $1 billion a year beyond the fund.
A Geissler tube is a precursor to modern gas discharge tubes, demonstrating the principles of electrical glow discharge, akin to contemporary neon lights, and central to the discovery of the electron. [1] : 67 This device was developed in 1857 by Heinrich Geissler, a German physicist and glassblower. A Geissler tube is composed of a sealed ...
