calculus. Calculus, which was discovered by Newton and Liebniz, nothwithstanding all credit being given to Newton, is one of the most beautiful forms of intellectual material. Calculus requires and emphasizes the development of new methods of thinking, and therefore it is not for the weak minded.
Bacterial gastroenteritis happens when bacteria causes an infection in your gut. This causes inflammation in your stomach and intestines. You may also experience symptoms like vomiting, severe abdominal cramps, and diarrhea. While viruses cause many gastrointestinal infections, bacterial infections are also common.
Because the bacteria enter the body through the digestive system, symptoms will generally be in this part of the body-nausea, vomiting, abdominal cramps and diarrhoea. In some cases, food poisoning can cause very serious illness or even death.hen someone swallows bacteria that cause food poisoning, there is a delay (incubation period) before symptoms begin. This is because most bacteria that cause food poisoning need time to multiply in the intestine. The length of the incubation period depends on the type of bacteria and how many are swallowed.
