Neutron scattering experiments have shown that the radius of the nucleus of an atom is directly proporitonal to the cube root of the number of nucleons in the nucleus. From_(3)7Lito_(76)189Osthe radius is: View Solution Free Ncert Solutions English Medium ...
Yet, dusty molecular gas seen in absorption against the quasar nucleus is highly excited and confined within cloudlets with densities of approximately 105 to 106 cm−3 and sizes of less than 0.02 pc, several orders of magnitude more compact than those observed in intervening (non-quasar)...
Here, we investigate the neurobiological basis of stress resilience, by showing that neural responsitivity of the noradrenergic locus coeruleus (LC-NE) and associated pupil responses are related to the subsequent change in measures of anxiety and depression in response to prolonged real-life stress....
The second flaw of the Kepler’s laws of planetary motion is that the three laws altogether implies a wrong viewpoint, that is, the orbits of all planets are in the same 2-D plane, this is impossible, in fact, modern observations indicate that, over a long period of time, the orbital...
Analyses in the radial direction were performed by varying the radius of the shell while keeping its z position fixed (supplemental Figure 2 and 3). These data gave a general impression of cellular features along the x and y axes and across tissues. They corroborated that meristematic briTRIPLE...
A selection of cells in a part of the brainstem called the pedunculopontine nucleus (PPN) could be responsible for this 'freeze frame' effect. The discovery not only helps us map the location of tissues that contribute to the more zen-like properties of the human mind, it could help us ...
“In any given interval of time, the total amount of mass-energy that a planet transferred into the Sun’s core is always greater than that of the mass-energy that the Sun transferred to the planet. The amount of the mass gained by the Sun is approximately equal to the total mass lost...
For a sphere of radius R, the relation between surface area and volume is 3/R. When R is small, the surface area–volume ratio is large. For a ratio similar to that of the lung, R ∼ 0.1 mm. 24. The Poiseuille flow, a steady fully developed flow in a straight pipe with a uni...
)], Kendall tau-b correlation scores were calculated based on the ranking of the cluster according to the level of accessibility of the chromatin fiber and the expression level of the gene. Positive and negative correlations are indicated by red and blue circles, respectively. The radius of ...
Animals generate neural representations of their heading direction. Notably, in insects, heading direction is topographically represented by the activity of neurons in the central complex. Although head direction cells have been found in vertebrates, the
