| mass law | <chemistry> This law states that the rate of a given chemical reaction is proportional to concentration of the reactants. (09 Oct 1997) |
|---|---|
| Pascal's law | Fluids at rest transmit pressure equally in every direction. (05 Mar 2000) |
| Virchow's law | There is no special or distinctive neoplastic cell, inasmuch as the component cells of neoplasms originate from preexisting forms. (05 Mar 2000) |
| Vogel's law | When a phenotype may be transmitted by various modes of mendelian inheritance, the dominant will have the least deleterious phenotype, the recessive the most, and the X-linked intermediate between the two. (05 Mar 2000) |
| Godelier's law | Tuberculosis of the peritoneum is always associated with tuberculosis of the pleura on one or both sides. (05 Mar 2000) |
| Meltzer's law | "all living functions are continually controlled by two opposite forces: augmentation or action on the one hand, and inhibition on the other." Synonym: law of contrary innervation. (05 Mar 2000) |
| Gompertz' law | The proportional relationship of mortality to age; after age 35-40, the increase in mortality with age tends to be logarithmic. (05 Mar 2000) |
| Mendeleeff's law | The properties of elements are periodical functions of their atomic weights; i.e., if the elements are arranged in the order of their atomic weights, every element in the series will be related in respect to its properties to the eighth in order before or after it. Synonym: periodic law. (05 Mar 2000) |
| Charles law | All gases expand equally on heating, namely, 1/273.16 of their volume at 0캜 for every degree Celsius. Synonym: Gay-Lussac's law. (05 Mar 2000) |
| Charles's law | <physics> The statement that the volume of a sample of gas is directly proportional to the temperature of the gas (at constant pressure). (13 Nov 1997) |
| Graham's law | <physics> The relative rapidity of diffusion of two gases varies inversely as the square root of their densities, i.e., their molecular weights. (05 Mar 2000) |
| periodic law | The properties of elements are periodical functions of their atomic weights; i.e., if the elements are arranged in the order of their atomic weights, every element in the series will be related in respect to its properties to the eighth in order before or after it. Synonym: periodic law. (05 Mar 2000) |
| Grasset's law | In lesions of one hemisphere, the patient's head is turned to the side of the affected muscles if there is spasticity and to that of the cerebral lesion if there is paralysis. Synonym: Grasset's law. (05 Mar 2000) |
| Ricco's law | <physics> For small images, light intensity X area = constant for the threshold. (05 Mar 2000) |
