Quantitative measurements of the liquid 4He density temperature dependence are taken near the λ point in a thin plane-parallel gap of thickness d=3.3×10 5 cm with a well controlled geometry. Evidence is obtained that there are three effects contributing to the average helium density in the ...
Particle Doppler shift spectroscopy (PDSS) is being used at NBS for measuring the size distribution of particles produced by aerosol generators, calibrating other types of particle sizing instruments, and studying the agglomeration, coalescence, evaporation, and condensation of liquid and solid aerosols....
If an inherent adhesion force between the liquid and solid surface exists, it would be a constant value regardless of whether a droplet size is large or not. However, it is unknown whether the adhesion force changes depending on the size of the droplet because most previous studies treat a ...
The microscopic particles that make up the Venusian clouds consist of liquid droplets and perhaps also solid crystals. The dominant material is highly concentratedsulfuric acid. Other materials that may exist there include solidsulfur, nitrosylsulfuric acid, andphosphoric acid. Cloud particles range in ...
What is allowed in a carry-on bag? What youpack in your carry-onbag is regulated, as well. In addition to the same rules that apply to checked bags, which prohibit firearms, lithium batteries, and other potentially hazardous items, you cannot bring containers of liquid, paste, aerosol, ge...
For each size, ten different samples are prepared according to this recipe beginning the quenching procedure from liquid configurations obtained initializing the atomic velocities with different random seeds. The average mass density of the amorphous samples is 2.275 g cm−3, with a standard ...
We interpret the particle radius \({r}_{i}\) as a random variable distributed according to the PSD \(p\left(r\right).\) The particle location \({x}_{i}\) is also a random variable uniformly distributed across the object plane. \(H(x)\) describes the surface height resulting from...
Development of microcracks in granitic rock by liquid CO2 fracturing Hydraulic fracturing by liquid carbon dioxide (LCO 2 ) generates fracture and cracking patterns that vary from those generated by water injection . The use... SJ Ha,Y Kim,TS Yun - 《International Journal of Rock Mechanics & ...
Size Segregation of Binary Granular Mixtures - Towards more appropriate scaling of percolation velocityWe study size segregation of binary granular mixtures flowing over an inclined plane using DEM simulations. We critically examine the recently... A Tripathi,M Nema - 《European Physical Journal Conferen...
backlight bleeding is a phenomenon where light from the backlight leaks through the liquid-crystal display (lcd) panel, causing uneven brightness and visible patches of light on the screen, particularly in dark or black areas. although ips monitors can exhibit backlight bleeding to some extent, ...
