International organizations, as the World Health Organization (WHO) and national governments are constantly defining (or modifying) new healthcare protocols and procedures. Those changes have a significant impact, on one side, on the organizational concerns of a great number of healthcare institutions and centers, and on the other side, on their health information systems that need to be adapte...

Replicate lineages of the bacteriophage phiX 174 adapted to growth at high temperature on either of two hosts exhibited high rates of identical, independent substitutions. Typically, a dozen or more substitutions accumulated in the 5.4-kilobase genome during propagation. Across the entire data set of nine lineages, 119 independent substitutions occurred at 68 nucleotide sites. Over half of thes...

abstract different factors such as the quality of ova and sperm are involved in propagation process. mobility percentage, ph, mobility duration, compaction and osmolarity of sperm which affect the quality of sperm were tested in this research. this study was carried out in april 2011 in shahid ansari bony fishes propagation and rearing center. according to the results, mean and standard deviati...

In this study, torsional wave propagation is investigated in a rod that are made of one and two dimensional functionally graded material. Firstly, the governing equations of the wave propagation in the functionally graded cylinder derived in polar coordinate. Secondly, finite difference method is used to discretize the equations. The Von Neumann stability approach is used to obtain the time ste...

Neural mass signals from in-vivo recordings often show oscillations with frequencies ranging from <1 to 100 Hz. Fast rhythmic activity in the beta and gamma range can be generated by network-based mechanisms such as recurrent synaptic excitation-inhibition loops. Slower oscillations might instead depend on neuronal adaptation currents whose timescales range from tens of milliseconds to seconds....
