The relation between density and velocity plays an important role in reservoir physical property research. According to the data of ultrasonic velocity and density of the core samples of the Jiyang Depression measured in laboratory,the effects of the factors of li-thology,porosity and permeability on...
We present an implementation of a method to determine different components of the local density of states in the presence of a core hole from inelastic x-ray scattering experiments. The only theoretical input needed beyond experimental data are the embedded atom transition matrix elements. In this ...
We attribute the observed higher melting temperatures of some of the clusters (viz.,Ga45–Ga48) to the presence of a distinct core and strong covalent bonds between the core and surface atoms. The present work clearly demonstrates that it is possible to understand the general trends observed ...
Based on the existing BIOSTAT(R) CultiBag STR concept [1], Sartorius has developed a number of pivotal innovations that allow for safe and well controlled high cell density mammalian cultures in single-use stirred tank bioreactors. First-of- all a single-use exhaust cooler (plate heat exchanger...
This is a tool with a potential to retrieve experimental electron densities even at hundreds of GPa pressures, (i.e. up to the pressures present in the Earth’s inner core). Such pressures are achieved with DACs of slightly different design and diamond cut. Multiple crystals in optimal ...
After a 60-min equilibration period, the outgoing perfusate was stored at −70 °C for subsequent analysis. After the microdialysis investigation, an unguided breast biopsy was obtained from the upper lateral quadrant of the left breast (MAX-CORE, gauge 14, BARD Medical, Covington, GA, ...
Most studies combine the SP2's incandescence and 1064 nm scattering data to report coating properties, but to date there is no consistency in the assumed values of density and refractive index of the core that are used in these calculations, which can greatly affect the reported parameters such...
As the initial galaxy model, we used an isothermal King model and placed a massive black hole at around the half-mass radius of the galaxy. We found that the central core of the galaxy is destroyed by the heating due to the black hole and that a very weak density cusp ($ho \\prop...
PURPOSE: Bradford's law describes the number of core journals in a given field or subject and has recently been applied to neurosurgery. The objective of this study was to use currently accepted formulations of Bradford's law to identify core journals of pediatric neurosurgery. An additional analy...
