Exsanguination itself originated from Latin: "ex" ("out of") and "sanguis" ("blood"). Exsanguination is used as a method of slaughter. Before the fatal incision is made, the animal may be rendered insensible to pain by various methods, including captive bolt, electricity or chemical. Without prior sedation, stunning or anesthetic, this method of slaughter causes a high degree of anxiety, although other religiously funded studies contradict these findings. The captive bolt is placed against the skull of the animal, and penetrates to cause tissue destruction in the brain, incapacitating the animal so that the procedure may take place. Electricity is used mostly to
Bresle method 8502-9 method it is calculated as a specific mixture of salts, but expressed as Sodium Chloride. Factors are applied to the measured conductivity, depending on what is known or assumed about the salt contamination and various conditions, in order to yield meaningful measurements of contamination. Some of the variables are: A common source of error is not knowing the composition of the contamination being measured. There are multiple suppliers of Bresle method test kits. The solubility in water depends on the type of salt. Sodium chloride can be dissolved in cold water to a concentration of 357 g∙l. Not only
