We derive the correlation patterns over global latitudes and from stratosphere to lower thermosphere (broadly referred as teleconnection) using temperature data measured by Sounding of Atmosphere Broadband Emission Radiometry (SABER) 2002 2010, 54 years simulations temperatures winds Whole Community Climate Model (WACCM). also analyze possible mechanisms teleconnection investigating correlations between residual circulation. The show that exists globally equatorial, mid‐ high‐latitudes,...
In this article, thermal gravimetric analysis and Fourier infrared-spectrum technology were used to analyze the change rules for critical temperature stage characteristics during a coal's spontaneous-combustion oxidation-reaction process. Different-metamorphic-degree-coal influence factors of characteristic temperatures studied. The coal showed an increase trend with heating rate. decreases; when rate oxygen concentration different, value was anthracite > bituminous lignite. functional...
Abstract Coal dust explosion accidents often cause substantial property damage and casualties frequently involve nano-sized coal dust. In order to study the impact of on methane–coal explosions, a pipe test apparatus was used analyze pressure characteristics five types micro-nano particle dusts (800 nm, 1200 45 μm, 60 75 μm) at concentrations (100 g/m 3 , 250 500 750 1000 ). The were closely related size concentration. maximum pressure, rate rise, deflagration index for larger than its...
This study utilizes COSMIC satellite and lidar observations to examine the spatial temporal variability of stratospheric temperature at a number scales. The geographic variation RMS difference between pairs profiles shows strong correspondence previous climatologies gravity wave activity. In addition, second‐order structure functions we form can be directly related horizontal power spectrum. These for different seasons altitudes display close studies which examined spectra. Our analysis...
Abstract Atmospheric pressure fluctuation is one of the most important factors affecting climate environment and gas emission in fire area. To obtain influence rule surface atmospheric change on sampling abnormal mine closed goaf, No. 1 coal Dananhu was taken as research object. Using Fourier transform Fisher harmonic analysis other statistical methods, periodic variation leakage outflow goaf studied. The results showed that there were three periods 15.2 d, d 182.2 probability greater than...
A good understanding of seepage flow distribution and the situation coal spontaneous three zones in goaf is great value to integrated control combustion. Based on theory analysis voidage permeability coefficient porous media goaf, this paper sets up a mathematical model analyzes air leakage field oxygen concentration with numerical software reveal variation law oxidation zone change wind velocity voidage. It provides scientific basis for fire source locating prevention combustion goaf.
Glioblastoma (GBM) is the most prevalent and fatal form of brain tumor, which associated with a poor prognosis. ATP-binding cassette subfamily F member 1 (ABCF1) an E2 ubiquitin-conjugating enzyme, implicated in regulating immune responses tumorigenesis. Aberrant E3 ubiquitylation has been evidenced GBM. However, role ABCF1 GBM needs to be further explored. The expression ABCF1, CXC chemokine ligand 12 (CXCL12), receptor 4 (CXCR4) tissues was examined by GEPIA tool, real-time PCR Western...
In the teaching of traditional mining and safety engineering, some undermine disasters cannot demonstrate intuitively, achieve desired effects. This article applies virtual reality into fire, explores a fire system on reality, demonstrates kinds phenomenon caused by fire. As result, it has great effects in teaching.
