Preparations are prepared, using completely clean slides and aqueous suspensions of young bacterial agar cultures. A drop of the suspension is placed on one end of the slide; the slide is then tipped, making the suspension drain down to the opposite end (Society of American Bacteriologists, Manual of Microbiological Methods, McGraw-Hill Book Co., New York, 1957). Both the mordanting and the sta...

In turbid media such as biological tissue, multiple scattering hinders direct light focusing at depths beyond one transport mean free path. As a solution to this problem, time-reversed ultrasonically encoded (TRUE) optical focusing is proposed based on ultrasonic encoding of diffused laser light and optical time reversal. In TRUE focusing, a laser beam of long coherence length illuminates a tur...

A six lump-based kinetic model has been developed for the hydrocracking of high-density polyethylene (HDPE) blended with vacuum gas oil (VGO) over a PtPd/HY zeolite catalyst. The blend (20 wt% HDPE and 80 VGO) hydrocracked in semi-continuous stirred tank reactor under following conditions: 400–440 °C; H2 bar; catalyst to feed (C/F) weight ratio, 0.05–0.1 gcat gfeed−1; reaction time, 15–120 min;...

Diameter-controlled Ag nanowires were rapidly fabricated (1 min) using inexpensive, abundant, and environmentally-friendly glycerol as both a reductant and solvent under non-stirred microwave irradiation conditions; no Ag particles were formed using conventional heating methods. The temperature and pressure of the reaction systems were monitored to investigate the role of microwaves in the asse...

Ammonium, phosphorus, and potassium from wastewater treatment with a coexisting ion of calcium may be recovered simultaneously through struvite struvite-(K) crystallization. This paper presents the quantitative assessment impact ions on kinetics crystallization those crystals. Initial solutions containing dose levels Ca2+ pH 9 were set up for experiments in stirred laboratory at ambient tempera...

Hydrogen may be considered a potential fuel for the future since it is carbon-free and oxidized to water as a combustion product. Bioconversion of synthesis gas (syngas) to hydrogen was demonstrated in continuous stirred tank bioreactor (CSTBR) utilizing acetate as a carbon source. An anaerobic photosynthetic bacterium, Rhodospirillum rubrum catalyzed water-gas shift reaction which was applied ...

Using a global database of 125 magnetometers covering several decades, we present occurrence statistics for fluctuations the horizontal geomagnetic field (dBh/dt) exceeding 99.97th percentile (P99.97) both ramp changes (Rn) and root-mean-square (Sn) over periods, ?, from 1 to 60 min describe their variation with latitude magnetic local time (MLT). Rates exceedance are explained by reference mag...
