The World Bank estimates that over 150 billion cubic metres of natural gas are flared or vented annually. Before natural gas can be used as a fuel, it must be processed to remove impurities, including water, to meet the specifications of marketable natural gas.
In neuroanatomy, a gyrus (pl. gyri) is a ridge on the cerebral cortex. It is generally surrounded by one or more sulci (depressions or furrows; sg. sulcus). Gyri and sulci create the folded appearance of the brain in humans and other mammals.achygyria (meaning thick or fat gyri) is a congenital malformation of the cerebral hemisphere, resulting in unusually thick gyri in the cerebral cortex. Pachygyria is used to describe brain characteristics in association with several neuronal migration disorders; most commonly relating to lissencephaly.
A gyrus is a fold or bulge in the brain. The cingulate gyrus is the curved fold that covers the corpus callosum. It is a component of the limbic system and involved in processing emotions and behavior regulation. It also helps to regulate autonomic motor function. The cingulate gyrus can be divided into anterior and posterior segments.
