"Trigynous" Natural Recordings by Native Speakers
Term used to describe a type of flowering plant that bears three carpels in its seed pod, or dry fruit, and is one of the basic reproductive systems found in plants. Examples of trigynous fruits include the banana and the fig.
In linguistics, a trigram is a sequence of three items, usually written or spoken, that are closely related in some way. In the context of language, trigrams are often used as a unit of measurement and analysis, particularly in text analysis and natural language processing (NLP).<br><br>In text analysis, a trigram is a sequence of three words that appear together in a sentence or paragraph. For example, "the sun is a good" is a trigram. Trigrams can be used to identify patterns and trends in language, including grammatical structures, syntactic relationships, and semantic connections.<br><br>In cryptography and coding theory, a trigram can refer to a triple of letters or symbols that replace a single character in a password or message. This is often used for encrypted communication, where each trigram serves as a key to decode the encrypted message.<br><br>Trigrams can also be used as the building blocks of more complex patterns, such as larger phrase chunks or phrases.
A trigraph is a sequence of three letters in a word or sound that is represented by a single sound. In the English language, there are several common trigraphs, including:<br><br> "chr" (as in "church")<br> "str" (as in "street")<br> "thr" (as in "thrive")<br> "sch" (as in "machine")<br> "spr" (as in "spring")<br> "dry" (as in "dryly")<br><br>Trigraphs can be confused with digraphs, which are sequences of two letters that represent a single sound. For example, the "sh" in "fish" is a digraph, while the "tch" in "kitchen" is a trigraph.<br><br>Trigraphs are often used in words to represent a single sound that would be difficult to write with a single letter or digraph. For example, the "ch" in "church" can be written more accurately with a trigraph "chr" to represent the consistent sound.<br><br>Overall, trigraphs are a useful tool in writing systems to help represent the complexities of the sounds of language.
Trichloromethane, also known as chloroform, is a trihalomethane (a methane molecule with three of its hydrogens replaced by chlorines). It is a general anaesthetic in the early 20th century, and is still used today as a precursor to several end products in the chemical industry, including refrigerants, solvents and pharmaceuticals.<br><br>It is often confused with dichloromethane (methylene chloride), which is a different, also trihalogenated methane though with only two hydrogen atoms, used as a solvent and in the manufacture of fluoropolymers such as Teflon.<br><br>Trichloromethane has been linked to the development of certain types of cancer, and it is also known to be toxic to the human liver.
Trihalomethanes, also known as THMs, are a group of organic compounds that are formed when chlorine or other disinfectants are used to purify and disinfect drinking water. They are a type of volatile organic compound (VOC) that can evaporate quickly.<br><br>Trihalomethanes are a concern because they have been linked to potential health risks, including:<br><br>1. Cancer: Some studies have suggested a possible link between long-term exposure to THMs and an increased risk of cancer, particularly bladder and colorectal cancer.<br>2. Reproductive problems: Exposure to THMs has been linked to reproductive problems, such as low birth weight and birth defects.<br>3. Neurological effects: Exposure to THMs has been linked to neurological effects such as headaches, dizziness, and liver damage.<br><br>The U.S. Environmental Protection Agency (EPA) has set a maximum contaminant level goal (MCLG) of zero for certain THMs, indicating that any level of exposure should be avoided. Some countries have also established guidelines for the maximum allowable concentration of THMs in drinking water.<br><br>Sources of trihalomethanes include:<br><br>1. Water treatment plants: When chlorine is used in disinfected water, it can form THMs.<br>2. Tap water: Drinking water that contains THMs can come from contaminated sources, infrastructure, or distribution systems.<br>3. Distribution systems: THMs can be formed when chlorine reacts with organic matter in pipes and distribution systems.<br><br>To reduce exposure to trihalomethanes, consumers can take the following precautions:<br><br>1. Use a water filter that reduces THMs, such as activated carbon or ion-exchange systems.<br>2. Check with your water utility to see if they use disinfection byproducts (DBPs) in their treatment process.<br>3. Use a home water treatment system that uses non-chlorine disinfection methods, such as ultraviolet (UV) light or ozone.
A chemical compound used as a medication for its antipsychotic properties, now largely discontinued due to side effects such as brain damage and tardive dyskinesia.
Trihydroxy refers to a chemical group or substituent that contains three hydroxyl (-OH) functional groups.
