Underground fires are still one of the most significant risks in mines today. In order to manage this risk, it is necessary know potential evolution a fire and effects can have on people other objects. Ventilation plays an essential role development fire; also influences propagation toxic fumes variation temperatures all areas mine. Currently, possible jointly analyze, through numerical modelin...

Electrically driven subwavelength scale metallo-dielectric pedestal pillar lasers are designed and experimentally demonstrated. The metallo-dielectric cavity significantly enhances the quality factor (Q > 1500) of the wavelength and subwavelength scale lasers and the pedestal structure significantly reduces the threshold gain (< 400 cm(-1)) which can potentially enable laser operation at room t...

There is an ancient and well-known Asian folk-tale that, in a version by the poet Rumi in Tales from the Masnavi, tells of four men who are asked to feel an elephant in a dark room and describe what they are sensing. Each of them touches just one part of the elephant, so they all reach different conclusions and think that they are in the presence of either a water-spout, a fan, a pillar, or a t...

As parallelism in microprocessors becomes mainstream, new programming languages and environments are emerging to meet the challenges of parallel programming. To support research on these languages, we are developing a lowlevel language infrastructure called Pillar (derived from Parallel Implementation Language). Although Pillar programs are intended to be automatically generated from source pro...

One of the most striking aspects of the cellular pattern within the sensory epithelium of the mammalian cochlea is the presence of two rows of pillar cells in the region between the single row of inner hair cells and the first row of outer hair cells. The factors that regulate pillar cell development have not been determined; however, previous results suggested a key role for fibroblast growth ...

Drain current multiplication in vertical MOSFETs due to body isolation by the drain depletion region and gate-gate charge coupling are investigated at pillar thicknesses in the range 200-10 nm. For pillar thickness > 120 nm depletion isolation does not occur and hence the body contact is found to be completely effective with no multiplication in drain current, whereas for pillar thicknesses < 6...

Purpose. Determining the patterns for geomechanical state changes in rock mass, depending on stoping face technological parameters sloping ore deposits. Methods. The state-of-the-art CAE Fidesys strength analysis system has been adopted to conduct research processes around face, which is effective a flat formulation. used provides complete engineering process cycle from preparation of calculati...

The first synthesis of a monohydroxy pillar[5]arene has been carried out, by controlling the de-O-methylation of per-methylated pillar[5]arene. Using monohydroxy pillar[5]arene as an intermediate, mono-guest-functionalized pillar[5]arene was prepared. It formed a self-inclusion complex in CDCl(3) whereas in acetone-d(6) dethreading of the guest moiety took place.
