Three variants of obelus glyphs. The dagger symbol originated from a variant of the obelus, originally depicted by a plain line − or a line with one or two dots ÷. [7] It represented an iron roasting spit, a dart, or the sharp end of a javelin, [8] symbolizing the skewering or cutting out of dubious matter.
Infants have been observed to fluctuate heavily when choosing a hand to lead in grasping and object manipulation tasks, especially in one- versus two-handed grasping. Between 36 and 48 months, there is a significant decline in variability between handedness in one-handed grasping; it can be seen earlier in two-handed manipulation.
Using this table, one must look up the significance level of the test based on the observed number of heterozygotes. For example, if one observed 20 heterozygotes, the significance level for the test is 0.007. As is typical for Fisher's exact test for small samples, the gradation of significance levels is quite coarse.
Two nuclei can only fuse into one if they approach each other closely enough; normally, nuclei (all positively charged) repel each other due to electrostatic repulsion. The strong interaction can overcome this repulsion but only within a very short distance from a nucleus; beam nuclei are thus greatly accelerated in order to make such repulsion ...
Following the example above, if one had a composite material made up of α and β phases under isostress conditions as shown in the figure to the right, the composition Young's modulus would be: = / (+) The isostrain condition implies that under an applied load, both phases experience the same strain but will feel different stress ...
This is a list of countries and territories by income inequality metrics, as calculated by the World Bank, UNU-WIDER, OCDE, and World Inequality Database, based on different indicators, like Gini coefficient and specific income ratios.
Tin-117 has a cross section of 2.3 barns, one order of magnitude smaller, while tin-119 has a slightly smaller cross section of 2.2 barns. [30] Before these cross sections were well known, it was proposed to use tin-lead solder as a coolant for fast reactors because of its low melting point.
Indians have a significant impact on the culture of the British capital. [citation needed] Within London, Southall, Hounslow, Brent, Croydon, Ealing, Barnet, Tooting, Harrow and Wembley, the latter of which is one of the few places outside India where Indians make up the largest ethnic group (almost 4 times larger than the White British ...
