introduction: in this paper, by complete definition of human eye containing the various parts and their materials, the difference between this model and a homogeneous water phantom are compared for two ophthalmic plaques using 125i and 103pd. material and methods: the simulation of the two phantoms were performed in the mcnp-4c code and by using the geometry of a three-dimensional eye, differen...

Eukaryotic protein synthesis initiation factor (eIF)-4C was purified from wheat germ and the molecular weight was calculated to be approximately 19,000 by SDS-polyacrylamide gel electrophoresis. A similar molecular weight was determined by gel filtration chromatography indicating that wheat germ eIF-4C is functional as a single polypeptide chain. An efficient in vitro translation system depende...

4C-Seq has proven to be a powerful technique to identify genome-wide interactions with a single locus of interest (or "bait") that can be important for gene regulation. However, analysis of 4C-Seq data is complicated by the many biases inherent to the technique. An important consideration when dealing with 4C-Seq data is the differences in resolution of signal across the genome that result from...

For companies developing and supplying equipment to the offshore industry, the degree of success is highly dependent on the reliability of delivered systems in operation. This comprises both operability and safety functions, and hence control systems need to go through extensive testing before being installed on new or existing systems. The possibility for testing a system in full scale before ...

A model of LGN-input to layer 4C of macaque primary visual cortex has been used to test the hypothesis that feedforward convergence of P- and M-inputs onto layer 4C spiny stellate neurons is sufficient to explain the observed gradual change in receptive field size and contrast sensitivity with depth in the layer. Overlap of dendrites of postsynaptic neurons between M- and P-input zones proved s...

Background: Miniature neutron sources with high neutron flux have abundant applications in medicine, industry and researches. The most important general characteristic of miniature neutron sources is their diameter which is 3mm in average. In this research, we have surveyed and designed an Am-Be miniature neutron source fabrication. Materials and Methods: This investigation resulted in creation...
