Filtration Coefficient
In physiology, filtration coefficient (Kf) is the product of a biological membrane's permeability to water and the surface area of the membrane. Typical units of Kf are mL/min/mmHg. The rate of filtration across the membrane is, by definition, the product of Kf and the net filtration pressure across the membrane. Kf is frequently applied to the glomerular capillaries, which filter water into Bowman's capsule to form urine. Typically, in an adult human, the net filtration pressure is 10mmHg and Kf 12.5mL/min/mmHg, giving a glomerular filtration rate (GFR) of 125mL/min. A decrease in Kf due to reduced number of glomeruli or reduced permeability will reduce the GFR at a given filtration pressure References {{portal bar, Medicine Renal physiology ...

Stability Constants Of Complexes
In coordination chemistry, a stability constant (also called formation constant or binding constant) is an equilibrium constant for the formation of a complex in solution. It is a measure of the strength of the interaction between the reagents that come together to form the Complex (chemistry), complex. There are two main kinds of complex: compounds formed by the interaction of a metal ion with a ligand and supramolecular complexes, such as host–guest complexes and complexes of anions. The stability constant(s) provide(s) the information required to calculate the concentration(s) of the complex(es) in solution. There are many areas of application in chemistry, biology and medicine. History Jannik Bjerrum (son of Niels Bjerrum) developed the first general method for the determination of stability constants of Metal ammine complex, metal-ammine complexes in 1941. The reasons why this occurred at such a late date, nearly 50 years after Alfred Werner had proposed the correct structur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Karl Fischer Titration
In analytical chemistry, Karl Fischer titration is a classic titration method that uses coulometric or volumetric titration to determine trace amounts of water in a sample. It was invented in 1935 by the German chemist Karl Fischer. Today, the titration is done with an automated Karl Fischer titrator. Chemical principle The elementary reaction responsible for water quantification in the Karl Fischer titration is oxidation of sulfur dioxide () with iodine: : H2O + SO2 + I2 → SO3 + 2 HI This elementary reaction consumes exactly one molar equivalent of water vs. iodine. Iodine is added to the solution until it is present in excess, marking the end point of the titration, which can be detected by potentiometry. The reaction is run in an alcohol solution containing a base, which consumes the sulfur trioxide and hydroiodic acid produced. Coulometric titration The main compartment of the titration cell contains the anode solution plus the analyte. The anode solution consists of ...

Freezing-point Depression
Freezing-point depression is a drop in the maximum temperature at which a substance freezing, freezes, caused when a smaller amount of another, non-Volatility (chemistry), volatile substance is added. Examples include adding salt into water (used in ice cream makers and for De-icing#Chemical de-icers, de-icing roads), Alcohol (chemistry), alcohol in water, Ethylene glycol, ethylene or propylene glycol in water (used in antifreeze in cars), adding copper to molten silver (used to make Solder#Hard_solder, solder that flows at a lower temperature than the silver pieces being joined), or the mixing of two solids such as impurities into a finely powdered drug. In all cases, the substance added/present in smaller amounts is considered the solute, while the original substance present in larger quantity is thought of as the solvent. The resulting liquid solution or solid-solid mixture has a lower Melting point, freezing point than the pure solvent or solid because the chemical potentia ...

Cryoscopic Constant
In thermodynamics, the cryoscopic constant, , relates molality to freezing point depression (which is a colligative property). It is the ratio of the latter to the former: :\Delta T_\mathrm = iK_\mathrm b * \Delta T_\mathrm is the depression of freezing point, defined as the freezing point T_\mathrm^0 of the pure solvent minus the freezing point T_\mathrm of the solution; * is the van ‘t Hoff factor, the number of particles the solute splits into or forms when dissolved; * is the molality of the solution. Through cryoscopy, a known constant can be used to calculate an unknown molar mass. The term "cryoscopy" means "freezing measurement" in Greek. Freezing point depression is a colligative property, so depends only on the number of solute particles dissolved, not the nature of those particles. Cryoscopy is related to ebullioscopy, which determines the same value from the ebullioscopic constant (of boiling point elevation). The value of , which depends on the natur ...

Vacuum Flange
A vacuum flange is a flange at the end of a tube used to connect vacuum chambers, tubing and vacuum pumps to each other. Vacuum flanges are used for scientific and industrial applications to allow various pieces of equipment to interact via physical connections and for vacuum maintenance, monitoring, and manipulation from outside a vacuum's chamber. Several flange standards exist with differences in ultimate attainable pressure, size, and ease of attachment. Vacuum flange types Several vacuum flange technical standard, standards exist, and the same flange types are called by different names by different manufacturers and standards organizations. KF/QF The International Organization for Standardization, ISO standard quick-release flange is known by the names Quick Flange (QF) or Kleinflansch (KF, German which translates to "Small flange" in English). The KF designation has been adopted by ISO, DIN, and Pneurop. KF flanges are made with a chamfered back surface that is attached with ...

Potassium Fluoride
Potassium fluoride is the chemical compound with the formula KF. After hydrogen fluoride, KF is the primary source of the fluoride ion for applications in manufacturing and in chemistry. It is an alkali halide salt and occurs naturally as the rare mineral carobbiite. Solutions of KF will etch glass due to the formation of soluble fluorosilicates, although HF is more effective. Preparation Potassium fluoride is prepared by reacting potassium carbonate with hydrofluoric acid. Evaporation of the solution forms crystals of potassium bifluoride. The bifluoride on heating yields potassium fluoride: : : Platinum or heat resistant plastic containers are often used for these operations. Potassium chloride converts to KF upon treatment with hydrogen fluoride. In this way, potassium fluoride is recyclable. Crystalline properties KF crystallizes in the cubic NaCl crystal structure. The lattice parameter at room temperature is 0.266 nm. Applications in organic chemistry In organic c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kalman Filter
In statistics and control theory, Kalman filtering (also known as linear quadratic estimation) is an algorithm that uses a series of measurements observed over time, including statistical noise and other inaccuracies, to produce estimates of unknown variables that tend to be more accurate than those based on a single measurement, by estimating a joint probability distribution over the variables for each time-step. The filter is constructed as a mean squared error minimiser, but an alternative derivation of the filter is also provided showing how the filter relates to maximum likelihood statistics. The filter is named after Rudolf E. Kálmán. Kalman filtering has numerous technological applications. A common application is for guidance, navigation, and control of vehicles, particularly aircraft, spacecraft and ships Dynamic positioning, positioned dynamically. Furthermore, Kalman filtering is much applied in time series analysis tasks such as signal processing and econometrics. K ...
