Percent active chlorine: Percent active chlorine is a unit of concentration used for hypochlorite-based bleaches. One gram of a 100% active chlorine bleach has the same bleaching power as one gram of chlorine.Chlorine dioxideVirkon: Virkon is a multi-purpose disinfectant. It contains oxone (potassium peroxymonosulfate), sodium dodecylbenzenesulfonate, sulfamic acid, and inorganic buffers.ChloramineFull mouth disinfection: Full mouth disinfection typically refers to an intense course of treatment for periodontitis typically involving scaling and root planing in combination with adjunctive use of local antimicrobial adjuncts to periodontal treatment such as chlorhexidine in various ways of application. The aim is to complete debridement of all periodontal pocket areas within a short time frame such as 24 hours, in order to minimize the chance of reinfection of the pockets with pathogens coming from another oral niches like the tongue, tonsils and non-treated periodontal pocket.Grand Harbor Resort and Waterpark: thumbnail|right|300px|The Grand Harbor Hotel, a portion of the Waterpark is visible in the right hand corner of this photo.Trioxide: A trioxide is a compound with three oxygen atoms. For metals with the M2O3 formula there are several common structures.Sodium hypochlorite: In dilution:TetraphenylporphyrinFecal coliform: A fecal coliform (British: faecal coliform) is a facultatively anaerobic, rod-shaped, gram-negative, non-sporulating bacterium. Coliform bacteria generally originate in the intestines of warm-blooded animals.Public water systemBromine dioxideJardine Water Purification PlantPhotoimmunotherapy: Photoimmunotherapy (PIT) is a new type of molecular targeted cancer therapy, which allows the selective destruction of cancer cells in mice without any damage to normal tissues. It is a light-based cancer therapy, which was developed by Professor Kobayashi and his colleagues at National Cancer Institute, Bethesda, Maryland.Halogenation: Halogenation is a chemical reaction that involves the reaction of a compound with a halogen and results in the halogen being added to the compound. Organic compounds undergo halogenation much more readily than inorganic compounds.Pheophorbidase: Pheophorbidase (, phedase, PPD) is an enzyme with system name pheophorbide-a hydrolase. This enzyme catalyses the following chemical reactionTemoporfinHypochlorous acidDichlorophenolDecontamination foam: Decontamination foam (known commonly as Decon foam) is a spray-on cleaning solution that, due to its physical properties, has a longer residence time on contaminated surfaces than regular liquids and thus provides efficient decontamination of biological and chemical contaminants (e.g.Performic acidVirus processing: The main idea behind viral processing is to stop the viruses in a given sample from infecting the desired product. The two most widely used methods of viral processing are viral removal and viral inactivation.Sterilization (microbiology): Sterilization (or sterilisation) is a term referring to any process that eliminates (removes) or kills (deactivates) all forms of life and other biological agents (such as prions, as well as viruses which some do not consider to be alive but are biological pathogens nonetheless), including transmissible agents (such as fungi, bacteria, viruses, prions, spore forms, unicellular eukaryotic organisms such as Plasmodium, etc.) present in a specified region, such as a surface, a volume of fluid, medication, or in a compound such as biological culture media.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).Ozone Action Day: An Ozone Action Day, which can be declared by a local municipality, county or state, is observed at certain times during the summer months, when weather conditions (such as heat, humidity, and air stagnation) run the risk of causing health problems.Electrolysis: In chemistry and manufacturing, electrolysis is a technique that uses a direct electric current (DC) to drive an otherwise non-spontaneous chemical reaction. Electrolysis is commercially highly important as a stage in the separation of elements from naturally occurring sources such as ores using an electrolytic cell.Timeline of chemical warfareMethyl halide transferase: Methyl halide transferase (, MCT, methyl chloride transferase, S-adenosyl-L-methionine:halide/bisulfide methyltransferase, AtHOL1, AtHOL2, AtHOL3, HMT, S-adenosyl-L-methionine: halide ion methyltransferase, SAM:halide ion methyltransferase) is an enzyme with system name S-adenosylmethionine:iodide methyltransferase. This enzyme catalyses the following chemical reactionPlumbing fixture: A plumbing fixture is an exchangeable device which can be connected to a plumbing system to deliver and drain water.Radiosensitizer: A radiosensitizer is a drug that makes tumor cells more sensitive to radiation therapy.Halogen dance rearrangement: The halogen dance rearrangement is an organic reaction in which a halogen substituent moves to a new position on an aromatic ring system. The reaction belongs to a class of organic reactions called 1,2-rearrangements.Alkaliphile: Alkaliphiles are a class of extremophilic microbes capable of survival in alkaline (pH roughly 8.5-11) environments, growing optimally around a pH of 10.
