Biofouling is the accumulation of aquatic organisms such as microorganisms, plants and animals on surfaces and structures immersed in or exposed to the aquatic environment.Biofouling can include pathogens. (IMO 2023 Guidelines for the control and management of ships' biofouling to minimize the transfer of invasive aquatic species (Biofouling Guidelines) https://wwwcdn.imo.org/localresources/en/KnowledgeCentre/IndexofIMOResolutions/MEPCDocuments/MEPC.378(80).pdf)
Popcorns are perhaps the most primitive of the surviving races of maize. This corn type is characterized by a very hard, corneous endosperm containing only a small portion of soft starch. Popcorns are essentially small-kerneled flint types. (http://corn.agronomy.wisc.edu/Management/pdfs/NCH10.pdf)
The pattern of any process, or the interrelationship of factors, which affects growth or changes within a population, including birth and death rates, immigration/emigration, etc. (FAO. WIEWS - World Information and Early Warning System on Plant Genetic Resources for Food and Agriculture https://www.fao.org/wiews/glossary/en/)
Refers to the manner in which a population is built up, through sub-populations of age classes, allele frequencies, etc. A population without any explicit division into sub-populations is considered continuous. Any deviation from the ideally continuous population, e.g. through inbreeding or selection, results in a structured population. (FAO. WIEWS - World Information and Early Warning System on Plant Genetic Resources for Food and Agriculture https://www.fao.org/wiews/glossary/en/)
Mechanical ventilation is the ventilation of a building by mechanical means (often fans) to bring fresh air from outside into a building and to regulate factors such as temperature and humidity within. (AGROVOC team)
Note
Use for mechanical if buildings. Do not use this concept <c_611e89cc> for mechanical ventilation in the medical sense (artificial ventilation where mechanical means are used to assist or replace spontaneous breathing.)
