Inert gas asphyxiation lacks oxygen and consists of an asphyxiant gas (one or more of argon, nitrogen or carbon dioxide), causing the animals to lose consciousness. Argon and nitrogen are important components of a gassing process which seem to cause no pain, and for this reason many consider some types of controlled atmosphere killing more humane than other methods of killing. However, "stunning" is often done using carbon dioxide. If carbon dioxide is used, controlled atmosphere killing is not the same as inert gas asphyxia, because carbon dioxide at high concentrations (above 5%) is not biologically inert, but rather is toxic and also
Most common words in Spanish of spoken Spanish. Most common words in Spanish Below are two estimates of the most common words in Modern Spanish. Each estimate comes from an analysis of a different text corpus. A "text corpus" is a large collection of samples of written and/or spoken language, that has been carefully prepared for linguistic analysis. To determine which words are the most common, researchers create a database of all the words found in the corpus, and categorise them based on the context in which they are used. The first table lists the 100 most common word forms from the Corpus de Referencia
