We have developed a 3D off-lattice stochastic polymerization model to study the subcellular oscillation of Min proteins in the bacteria Escherichia coli, and used it to investigate the experimental phenomenon of Min oscillation stuttering. Stuttering was affected by the rate of immediate rebinding of MinE released from depolymerizing filament tips (processivity), protection of depolymerizing fi...

The robot mine clearing, based on cheap and widespread farming contrivances, provides considerably unusual prospects, which aim at enhancing safety, reliability and efficiency, to transform the terrorist anti-personnel mine into almost useless practice. The talk develops along the following lines: • to conceive and implement low-cost robotic equipment, assuring effective, safe and reliable demi...

According to statistics, the coal spontaneous combustion fire accounted for more than 94% of the total number of coal mine fire, of which 60% occur in gob [1]. With the mining depth increasing, coal pillar become so easy to be crushed that coal spontaneous combustion is easier to occur. The fire’s occurrence and development not only affect the safety in production and the surrounding environmen...

Purpose. In order to fully exploit the metal and facilitate its method of processing, we need an accurate knowledge composition, granular distribution, association with unimportant penalizing elements that would like get rid of, compared distribution element extract by flotation method. Methodology. The present experimental work proposes approach mineralogical, chemical particle size characteri...

Excessive water inflow in a mine poses great threat to its operation, especially the case of salt mine. In 1992, rapid outflow occurred Mina traverse Wieliczka Salt Mine, and number investigations were undertaken assess causes condition rock mass, including gravity microgravity surveys discussed this paper. The first these was investigate mass with respect geological, hydrogeological properties...

The geochemical behavior of zinc, lead and copper from sulfidic tailings in a mine site with potential to generate acidic drainage (pyrite (55%) and sphalerite (2%)) is reported in this paper. The mining area is divided in two zones, considering the topographic location of sampling points with respect to the tailings pile: (a) outer zone, out of the probable influence of acid mine drainage (AMD...

Based on micro-Raman spectroscopy (m-Raman), micro X-ray fluorescence spectrometry (m-XRF), X-ray diffractometry (XRD) and optical microscopy, this paper presents the results of our analytical studies on the early Islamic pigments used in the Masjid-i Jame of Fahraj, central Iran. Our investigations showed that ultramarine blue and haematite were used as blue and red pigments, respectively. Mor...
