IOP is usually measured in an indirect way by measuring the tension on the surface of the eye‚ which is extrapolated to estimate the internal pressure. Therefore‚ methods to measure the IOP are influenced by corneal properties‚ like thickness and biomechanics. The Goldmann Applanation Tonometer (GAT) remains the most common method and the gold standard for measuring IOP. (Clement et al.‚ 2016). Principle of GAT: The GAT depends on the Imbert-Fick principle‚ which states that the pressure inside

Experiment # 1 Date: 18/12/13 Title: Chemical Properties of Alkanes. Aim: To test the reactivity of alkanes using cyclohexane as an example. Apparatus/Materials: Cyclohexane‚ liquid alkane‚ aqueous bromine‚ test tubes‚ light source‚ watch glass‚ splint‚ 0.1 MKMnO4‚ concentrated H2SO4‚ dilute H2SO4. Method: Combustion: 1. A watch glass was placed on a benched protection sheet in a fume cupboard and the extractor in the fume on. 2. 4 drops of cyclohexane was placed on the watch glass using

When assessing the combined results‚ to that of the results of the entire class‚ I determined that the results of the entire class are less accurate in matching the ideals of the Vitruvian man. This is due to the outliers

qid=20081221194214AAiRt42 ------------------------------------------------- The "Least Count" of any measuring equipment is the smallest quantity that can be measured accurately using that instrument.Thus Least Count indicates the degree of accuracy of measurement that can be achieved by the measuring instrument. All measuring instruments used in physics have a least count. A meter ruler’s least count is 0.1 centimeter; an electronic scale has a least count of 0.001g‚ although this may vary; a vernier

and error of a measurement Apparatus 1. Ruler Theory Human Reaction Time is a measure of how quickly human can respond to a particular stimulus. This experiment is done by dropping a ruler and measuring the distance the ruler falls. On this experiment‚ the purpose of conducting the human reaction time is as an example indirect measurement‚ where the direct measurements which is the distance the ruler is falling is calculated in order to calculate the indirect measurement which is the reaction

In order to carry out the measurement process‚ controllership focuses on the assessment of resources deployment and goal attainment Numerous research initiatives have identified the high correlation between superior performances and the development and use of sophisticated assessment or measurement capabilities. As early as 1985‚ A. T. Kuarney Consultants noticed that firm engaging

JIS ASTM ISO K 0070 D 5558 3657 Standard Test Method for Fat and Oil 1.Abstract Saponification value is expressed by potassium hydroxide in mg required to saponify one (1) gram of fat. It depends on the kind of fatty acid contained in the fat. Measurement of saponification value is performed according to the below listed official test methods. Here we test a sample of fatty acid. The sample is first saponified by adding 0.5mol/L potassium hydroxide ethanol‚ and then the excessive potassium hydroxide

For examples random error‚ systematic error and gross error are static error (i) random errors Random errors are ones that are easier to deal with because they cause the measurements to fluctuate around the true value. If we are trying to measure some parameter X‚ greater random errors cause a greater dispersion of
