Examples of postulate in the following topics:
-
- Koch's postulates are four criteria designed in the 1880's to establish a causal relationship between a causative microbe and a disease.
- Koch's postulates are four criteria designed to establish a causal relationship between a causative microbe and a disease.
- The postulates were formulated by Robert Koch and Friedrich Loeffler in 1884 and refined and published by Koch in 1890.
- Therefore, while Koch's postulates retain historical importance and continue to inform the approach to microbiologic diagnosis, fulfillment of all four postulates is not required to demonstrate causality.
- Koch's postulates have also influenced scientists who examine microbial pathogenesis from a molecular point of view.
-
- Even in Koch's time, it was recognized that infectious agents could be responsible for disease without fulfilling all of the postulates.
- Koch's postulates were developed in the 19th century as general guidelines to identify pathogens that could be isolated with the techniques of the day.
- Currently, a number of infectious agents are accepted as the cause of diseases despite their not fulfilling all of Koch's postulates.
- Therefore, while Koch's postulates retain historical importance and continue to inform the approach to microbiologic diagnosis, fulfillment of all four postulates is not required to demonstrate causality.
- In summary, a body of evidence that satisfies Koch's postulates is sufficient but not necessary to establish causation.
-
- Special relativity is based on Einstein's two postulates: the Principle of Relativity and the Principle of Invariant Light Speed.
- With two deceptively simple postulates and a careful consideration of how measurements are made, Einstein produced the theory of special relativity.
- This postulate relates to reference frames.
- This postulate might sound easy to accept, but it is rather counterintuitive.
-
- Postulate one: Everyone expects death, and one's abilities will likely deteriorate over time.
- Postulate four: The individual's life is punctuated by ego changes.
- Postulate six: Man's central role is work, and woman's is marriage and family.
- Postulate nine: Disengagement theory is independent of culture, but the form it takes is bound by culture.
- Analyze the nine postulates of growing old and the impact at each stage for the elderly in society
-
- Robert Koch identified anthrax as a disease agent and formulated postulates that are still used to research diseases today.
- Probably as important as his work on tuberculosis, for which he was awarded a Nobel Prize in 1905, are Koch's postulates.
- These postulates stated that to establish that an organism is the cause of a disease, it must be found in all cases of the disease examined.
-
- The use of these new methods has led to revised versions of Koch's postulates.
- Molecular Koch's postulates are a set of experimental criteria that must be satisfied to show that a gene found in a pathogenic microorganism encodes a product that contributes to the disease caused by the pathogen.
- Genes that satisfy molecular Koch's postulates are often referred to as virulence factors (i.e., what makes the pathogen virulent).
- The following set of Koch's postulates for the 21st century have been suggested:
-
- Wave–particle duality postulates that all physical entities exhibit both wave and particle properties.
- Wave–particle duality postulates that all physical entities exhibit both wave and particle properties.
- In 1905, Albert Einstein explained the photoelectric effects by postulating the existence of photons, quanta of light energy with particulate qualities.
-
- TST postulates three major factors that determine whether or not a reaction will occur.
- This third postulate acts as a kind of qualifier for something we have already explored in our discussion on collision theory.
-
- Expectancy Theory postulates that an individual's motivation can be derived through identifying an appropriate expectation.
-
- Alexander Fleming observed antibiosis against bacteria by a fungus of the genus Penicillium and postulated the effect was mediated by an antibacterial compound named penicillin whose antibacterial properties have been widely exploited for chemotherapy.
- Fleming postulated the effect was mediated by an antibacterial compound named penicillin, and that its antibacterial properties could be exploited for chemotherapy.
