Neutrons strike the heavy uranium nucleus, which splits, releasing a tremendous jolt of energy along with two or more neutrons, which split more nuclei, setting off a chain reaction that grows and grows and finally manifests itself as a huge fireball over a populated area, blinding, asphyxiating, incinerating, or crushing every living being within a five-mile radius".
Antoni A tissue is cellular and consists of monomorphic spindle-shaped Schwann cells, with a poorly defined eosinophilic cytoplasm and pointed basophilic nuclei, set in a variable collagenous stroma [30].
But algae are on the other side of the great dividing line of life, that between creatures with a simple, single genome which is just a big loop of DNA sitting in the cell and those with genomes that are for the most part sequestered in a nucleus set aside for them, and cut up into multiple chromosomes.
Identified nuclei were set as a region of interest (ROI) and applied as mask to the Jacob staining.
Filters for apoptotic bodies and micronuclei (versus nuclei) were set at H2afva-EGFP fluorescing body ≤3 µm.
A protocol for automatic count of the total amount of nuclei was set up for each hippocampal zone with the Volocity 5.4 3D imaging software (PerkinElmer, Coventry, United Kingdom).
By convention in DNA cytometry, nuclear DNA content is measured in relative units 'c', in which the DNA content of normal, non-tumour nuclei is set at 2c.
If the relative strength of the electromagnetic force between two protons separated by the distance within the nucleus was set equal to one, the strength of the gravitational force would be only 10−36.
But Hidefumi Waki and Julian Paton of Bristol University think they have gathered some valuable new intelligence by studying the brain.In a previous experiment Dr Waki and Dr Paton had found that rodents with high blood pressure expressed some genes differently in an area of the brain, called the solitary nucleus, which sets the body's normal blood-pressure level.
The tone of the first syllable vocalic nucleus was set to two different levels: a straight linear (high) tone throughout the vowel or a linear fall.
The duration of each first syllable nucleus was set to five different values, with a 25 millisecond difference between the values (75, 100, 125, 150, and 175 ms).
