Thin Film Electronics ASARed Noses: Red Noses is a comedy about the black death by Peter Barnes, first staged at Barbican Theatre in 1985. It depicted a sprightly priest, originally played by Antony Sher, who travelled around the plague-affected villages of 14th century France with a band of fools, known as God's Zanies, offering holy assistance.To Kau Wan: To Kau Wan () is a bay on the north shore of northeast Lantau Island, Hong Kong. Contaminated soil from Penny's Bay was transferred here for thermal desorption to separate the Volatile Organic Compounds (VOC) and Semi-Volatile Organic Compounds (SVOC) along with cement immobilization of metal contamination from Penny's Bay.Conductometry: Conductometry is a measurement of electrolytic conductivity to monitor a progress of chemical reaction. Conductometry has notable application in analytical chemistry, where conductometric titration is a standard technique.Ammonia volatilization from urea: Urea (46-0-0) accounts for more than fifty percent of the world’s nitrogenous fertilizers.Schwab, G.Volumetric heat capacity: Volumetric heat capacity (VHC), also termed volume-specific heat capacity, describes the ability of a given volume of a substance to store internal energy while undergoing a given temperature change, but without undergoing a phase transition. It is different from specific heat capacity in that the VHC is a 'per unit volume' measure of the relationship between thermal energy and temperature of a material, while the specific heat is a 'per unit mass' measure (or occasionally per molar quantity of the material).Acidovorax konjaci: Acidovorax konjaci is a Gram-negative bacterium. It can cause a plant disease, the leaf blight of Amorphophallus rivieri, a food crop of Japan.Fluorescent glucose biosensor: Fluorescent glucose biosensors are devices that measure the concentration of glucose in diabetic patients by means of sensitive protein that relays the concentration by means of fluorescence, an alternative to amperometric sension of glucose. No device has yet entered the medical market,No fluorescent biosensor has yet entered the medical market, however, in the market for research tools several fluorescent biosensors are present, such as a kit using [Vibrio fischeri] but, due to the prevalence of diabetes, it is the prime drive in the construction of fluorescent biosensors.Helsinki Motor ShowRefrigerant: A refrigerant is a substance or mixture, usually a fluid, used in a heat pump and refrigeration cycle. In most cycles it undergoes phase transitions from a liquid to a gas and back again.RV coefficient: In statistics, the RV coefficientHans GaffronMicrobalance: A microbalance is an instrument capable of making precise measurements of weight of objects of relatively small mass: of the order of a million parts of a gram. In comparison, a standard analytical balance is 100 times less sensitive; i.Luis Gabriel Cano: Luis Gabriel Cano Isaza (1924-2010)El Espectador obituary (In Spanish) was the President and publisher of El Espectador who won the Golden Pen of Freedom Award in 1990 for his writings on the cocaine traffic. His brother Guillermo, who had also worked on the paper, had been assassinated by drug gangs.Mechanical filter: A mechanical filter is a signal processing filter usually used in place of an electronic filter at radio frequencies. Its purpose is the same as that of a normal electronic filter: to pass a range of signal frequencies, but to block others.Modified Maddrey's discriminant function: The modified Maddrey's discriminant function) was originally described by Maddrey and Boitnott to predict prognosis in alcoholic hepatitis. It is calculated by a simple formula:SinensetinOrganic semiconductor: An organic semiconductor is an organic material with semiconductor properties, that is, with an electrical conductivity between that of insulators and that of metals. Single molecules, oligomers, and organic polymers can be semiconductive.Pasteurization: Pasteurization (American English) or pasteurisation (British English) is a process that kills bacteria in liquid food.Rice winePhysical neural network: A physical neural network is a type of artificial neural network in which an electrically adjustable resistance material is used to emulate the function of a neural synapse. "Physical" neural network is used to emphasize the reliance on physical hardware used to emulate neurons as opposed to software-based approaches which simulate neural networks.Shape theory of olfaction: The Shape theory of smell proposes that a molecule's smell character is due to its molecular shape, molecular size and functional groups. It has also been described by a 'lock and key' mechanism by which a scent molecule fits into olfactory receptors in the nasal epithelium.Nasal septal hematoma: Nasal septal hematoma is a condition affecting the nasal septum. It can be associated with trauma.Erythromycin breath test: The erythromycin breath test (ERMBT) is a method used to measure metabolism (oxidation and elimination from the system) by a part of the cytochrome P450 system. Erythromycin is tagged with carbon-14 and given as an intravenous injection; after 20 minutes the subject blows up a balloon and the carbon dioxide exhaled that is tagged with carbon-14 shows the activity of the CYP3A4 isoenzyme on the erythromycin.Cable fault location: Cable fault location is the process of locating periodic faults, such as insulation faults in underground cables, and is an application of electrical measurement systems. In this process, mobile shock discharge generators are among the devices used.Beta encoder: A beta encoder is an analog to digital conversion (A/D) system in which a real number in the unit interval is represented by a finite representation of a sequence in base beta, with beta being a real number between 1 and 2. Beta encoders are an alternative to traditional approaches to pulse code modulation.
