Here we present a novel concept for the selective recognition of different target gases with a multilayer semiconducting metal oxide (SMOX)-based sensor device. Direct current (DC) electrical resistance measurements were performed during exposure to CO and ethanol as single gases and mixtures of highly porous metal oxide double- and single-layer sensors obtained by flame spray pyrolysis. The re...

The low-friction properties of quasicrystal surfaces suggest their use as coatings on moving machine parts, including those in internal combustion engines. In such applications, additional lubricants are typically used. Since the low-friction properties of quasicrystals are thought to depend on their aperiodic structures, the interactions of lubricants on quasicrystalline surfaces may have an i...

Packaging and storage are the final phases in the food industry. Quality preservation, improving safety and reduction of postharvest losses waste are some objectives of the packaging engineering. One of techniques that widely used in packaging of fruits and vegetables are modified atmosphere packaging (MAP). In MAP for fresh fruits and vegetable the air of packaging headspace replaces with a pr...

Third Nephi 8 preserves a written account of a natural disaster at the time of Christ’s death that many assume to have been caused by volcanic activity. In a modernday science quest, the author examines research done on glacial ice cores from Greenland and Antarctica. Ice-core records can reveal volcanic gases and ashes that are carried throughout the world—the gases are detected by measuring t...

A brief survey is giveen of the effects of different pressures on living organisms. Highoxygen partial pressures inhibit oxidative metabolism and, according to Gersehman, have effects which summate at some point with the effects of radiation. In a study of the mechanism of the narcotic effect of inert gases, it was found that high pressures of nitrogen and argon, but not helium, act like other ...

Granular materials partake almost dramatically at times of the properties of solids and, under different circumstances, of some properties of gases. Some scientists have suggested that they represent a new state of matter, to be treated per se; because of their ambiguity the search of an overall continuum model for these media is quite intriguing. Even if one confines inquiry to fast flows of s...

Introduction: The KLE98300 meteorite is an Antarctic meteorite and is classified as an EH3 chondrite [1]. In this meteorite, we found large numbers of graphite grains associated with Fe-Ni metal. Such graphite grains are considered to be products of parent body metamorphism [2, 3]. Isotopic compositions of carbon and nitrogen in graphite and in bulk meteorites give important clues to the parent...

A Legendre expansion of the scattering kernel, a conservation condition and some exact solutions are reported for the McCormack kinetic model that is used to describe a binary mixture of rarefied gases.  2005 Elsevier SAS. All rights reserved.

Dense fluids, defined to include both dense gases and liquids, have the reputation of being especially difficult to deal with theoretically. This reputation is not undeserved. Unlike dilute gases and crystalline solids, which can be thought of as deviants from well understood ideal states, the ideal gas and the ideal harmonic crystal, the dense fluid lies far from any recognizable landmark. Thi...

Peabody in 1912 (1) published a paper on the metabolism in pneumonia, in which he reviewed the previous literature and studied among other factors the blood gases and acid-base balance. Since Peabody, a number of other investigators have studied the blood gases and the question of the existence and importance of acidosis in pneumonia. The present paper is a report of observations on these subje...
