Navy research shows that water delivered as a fine mist (or fog) is more effective than sprays in suppressing large scale fires[1, 2]. Fine mists have three distinct advantages. First, the small drop sizes that make up the mist allow the water to reach obstructed fires more easily than larger spray drops. Secondly, the water mist system has a lower water demand than the spray system. Lastly, sm...

Results of a detailed examination of the cascade nucleosynthesis resulting from the putative hadronic decay, evaporation, or annihilation of a primordial relic during the Big Bang nucleosynthesis (BBN) era are presented. It is found that injection of energetic nucleons around cosmic time 10sec may lead to an observationally favored reduction of the primordial Li/H yield by a factor 2 − 3. Moreo...

Evaporation of water droplets on a superhydrophobic substrate, on which the contact line is pinned, is investigated. While previous studies focused mainly on droplets with contact angles smaller than 90°, here we analyze almost the full range of possible contact angles (10°-150°). The greater contact angles and pinned contact lines can be achieved by use of superhydrophobic carbon nanofiber sub...

We investigated how temperature and precipitation regime encountered over the life cycle of Aedes albopictus (Skuse) affects populations. Caged populations of A. albopictus were maintained at 22, 26, and 30 degrees C. Cages were equipped with containers that served as sites for oviposition and larval development. All cages were assigned to one of three simulated precipitation regimes: (1) low f...

The quantum properties of charged black holes (BHs) found by McGuigan, Nappi and Yost are studied in 2D dilaton-Maxwell gravity (spontaneously compactificated from heterotic string) with N dilaton coupled scalars. Working in large N approach we discuss the presence of stable (evaporating) and unstable (anti-evaporating) modes in the spectrum of quantumcorrected BH. It is proved that charged 2D ...

Explicit expressions for arrival times of particles moving in a one-dimensional zero-range process (ZRP) are computed. Particles are fed into the ZRP from an injection site and can evaporate from any site of the one-dimensional lattice. Two dynamics are considered: bulk dynamics, where particle hopping and decay are proportional to the number of particles at each site, and surface dynamics, whe...

Characterization and modeling of metal-semiconductor-metal (MSM) GaAs diodes using to evaporate SiO₂ and Pd simultaneously as a mixture electrode (called M-MSM diodes) compared with similar to evaporate Pd as the electrode (called Pd-MSM diodes) were reported. The barrier height (φ(b)) and the Richardson constant (A*) were carried out for the thermionic-emission process to describe well the cur...
