in this work, we had examined 7 different types of neutron sources -an isotropic point source, sending 14.1(mev) monoenergetic neutrons ,an spherical source with 30 micron radius sending 14.1 (mev) monoenergetic neutrons, and a 30 micron radius spherical source having gaussian fusion energy spectrum from a d-t fusion, with different bandwidths -1,10,50,100 and 1000 kev and investigated 5 differ...

Mitochondria are dynamic organelles and continuously undergo fission and fusion processes. Mitochondrial fission is involved in multiple physiological or pathological processes, but the role of mitochondrial fission of smooth muscle cells in artery constriction is unknown. The role of mitochondrial fission of smooth muscle cells in arterial function was investigated by measuring the tension of ...

Opposing fission and fusion events maintain the yeast mitochondrial network. Six proteins regulate these membrane dynamics during mitotic growth-Dnm1p, Mdv1p, and Fis1p mediate fission; Fzo1p, Mgm1p, and Ugo1p mediate fusion. Previous studies established that mitochondria fragment and rejoin at distinct stages during meiosis and sporulation, suggesting that mitochondrial fission and fusion are ...

Prompt and $\beta$-delayed fission observables, such as the average number of prompt delayed neutrons, independent cumulative product yields, $\gamma$-ray energy spectra for photonuclear reactions on $^{235,238}$U $^{239}$Pu are calculated with Hauser-Feshbach Fission Fragment Decay (HF$^3$D) model compared available experimental data. In analysis neutron-induced to case photo-induced fission, ...

Most of the genetic divergence that currently separates populations of Homo sapiens must have arisen during that long period when the local village (or band) was the basic unit of biological evolution. Studies of tribally intact Amerindian groups exhibiting such small-group organization have demonstrated marked genetic divergence between nearby villages. Some of this genetic radiation can be at...

The mergers of binary neutron stars, as well black hole-neutron star systems, are expected to produce an electromagnetic counterpart that can be analyzed infer the element synthesis occurred in these events. We investigate one source uncertainties pertinent lanthanide-rich outflows: nuclear inputs rapid capture nucleosynthesis calculations. begin by examining thirty-two different combinations i...

In reactor calculations, a detailed 3-D power density distribution is required for core optimization studies and safety analyses. The general Monte Carlo based neutral particle transport tool, MCNP [1], has the capability to obtain detailed power density distribution in a reactor through its criticality calculation mode (KCODE mode). However, there is no standard tally type in MCNP that is able...

Measurements of mass and angular distributions have been made for fission-like outcomes in reactions forming isotopes flerovium (Z=114), using 48Ca, 50Ti, 54Cr projectiles. The dominant fast quasifission process, which masks the presence fusion-fission, has minimum yield at most backward angles, where sensitivity to fusion-fission is thus highest. In fitting angle spectra, only weak evidence a ...

Apatite [Ca5(PO4)3(F,Cl)] is a common mineral in rocks that contains ~10 ppm U. U disintegrates by spontaneous fission and the fission fragments produce linear damage trails of ~20 μm length and 5-10 nm width. The lattice damage along such a fission track is repaired at elevated temperatures, leading to a gradual decrease of its etchable length. Since fresh tracks are formed as existing tracks ...
