We report on a survey of NH2D towards protostellar cores in low–mass star formation and quiescent regions in the Galaxy. Twenty–three out of thirty-two observed sources have significant (∼5σ) NH2D emission. Ion–molecule chemistry, which preferentially enhances deuterium in molecules above its cosmological value of 1.6× 10 sufficiently explains these abundances. NH2D/NH3 ratios towards Class 0 s...

an analytical equation of state (eos) developed by ihm-song-mason (ism) has been applied tocalculate some thermophysical properties of molten polymers including poly (1-octene) (po), poly (vinylmethyl ether) (pvme), poly (vinyl chloride) (pvc), and poly (styrene) (ps). three temperature-dependentparameters of the ism eos have been determined based on the alternative scaling constants, dispersiv...

We numerically investigate how minor and major galaxy merging between two late-type disks affects mass distribution of interstellar medium (ISM) surrounding the haloes of disk galaxies. The purpose of this study is to explore dynamical effects of galaxy merging on gas replenishment from galactic haloes, which is generally considered to play vital roles in various aspects of disk galaxy evolutio...

W e are pleased to present this special issue of invited papers from the IEEE International Symposium on Multimedia (ISM), which was held in San Jose, California, 11–13 December 2016. As in past years, this collaboration between IEEE MultiMedia and the ISM organizers facilitates the processing of extended versions of the top 10 ISM papers through a fast-track review and publication schedule. We...

Thought disorder (TD) has been shown to vary in relation to negative affect. Here we examine the role internal source monitoring (iSM, i.e. ability to discriminate between inner speech and verbalized speech) in TD and whether changes in iSM performance are implicated in the affective reactivity effect (deterioration of TD when participants are asked to talk about emotionally-laden topics). Eigh...

We discuss the role of ambipolar diffusion for simple reconnection in a partially ionized gas, following the reconnection geometry of Parker and Sweet. When the recombination time is short the mobility and reconnection of the magnetic field is substantially enhanced as matter escapes from the reconnection region via ambipolar diffusion. Our analysis shows that in the interstellar medium it is t...

We numerically investigate chemodynamical evolution of interstellar medium (ISM) in gas-rich disk-disk galaxy mergers in order to explore the origin of fundamental chemical properties of halo ISM observed in elliptical galaxies. Main results obtained in this chemodynamical study are the following three. (1) Elliptical galaxies formed by gas-rich mergers show steep negative metallicity gradients...

A culture conducive to information security practice is extremely important for organizations since information has to be critical assets in modern enterprises. Thus for understanding and improving the organizational behavior with regard to information security, enterprises may look into organizational culture and examine how it affects the effectiveness of implementing ISM. This study aims ...
