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.
The convolutions on the surface of the cerebral cortex are called gyri (singular term is gyrus). Each gyrus of the cerebral cortex has a name and is often used in neurolinguistic descriptions.They are named mainly according to their location.eing components of the human brain it becomes important to know the difference between gyri and sulci. Human brain is one of the most complex organs in the human body. It is responsible for carrying out a huge number of functions, which are done by the nervous system.
