In a sample of local active galactic nuclei (AGNs) studied at a spatial resolution on the order of 10 pc, we show that the interstellar medium traced by the molecular hydrogen ν=1-0 S(1) line at 2.1 μm forms a geometrically thick, clumpy disk. The kinematics of the molecular gas reveals general rotation, although an additional significant component of random bulk motion is required by the high ...

Certain heavy oils which foam under severe depressurization give rise to increased recovery factor and an increased rate of production under solution gas drive. These oils not only stabilize foam, but also stabilize dispersion of gas bubbles at lower volume ratios. The way this phenomenon is related to the chemistry of the oil and its viscosity is presently not understood. We present here a mat...

We explore the physics of a spin-1/2 Heisenberg chain with Kondo interaction, ${J}_{k}$, to two-dimensional electron gas. At weak ${J}_{k}$ problem maps onto locally coupled dissipative Ohmic bath. decoupled fixed point, dissipation is marginally relevant perturbation and drives long-range antiferromagnetic order along chain. In dynamical spin structure factor we observe quadratic low-energy di...

The analytical theory of one dimensional, dispersion free miscible displacement of oil by injection gas with nc component has shown that: the MMP is the lowest pressure at which any one of the initial oil, injection gas or crossover key tie lines becomes critical, which means that its length approaches to zero. In this paper, we propose a method for a solving multi component syst...

Mars Atmosphere and Volatile Evolution Mission’s (MAVEN) high-cadence measurements reveal the frequent occurrence of ion energy dispersion events inside the Martian magnetosphere. The systematics of observed dispersion signatures suggest time dispersion of a broad source spectrum over a flight distance of a few thousand kilometers and disfavormechanisms involving spatial dispersion. Pickup of h...

We present predictions for the structural and photometric properties of early-type galaxies in the cold dark matter cosmology (ΛCDM) from the published semianalytical galaxy formation models of Baugh et al. and Bower et al. These calculations were made with the GALFORM code, which tracks the evolution of the disc and bulge components of a galaxy, using a self-consistent model to compute the sca...

Toxic or flammable gas release accident will possible form dangerous vapor cloud, which is of significant concerns to industrial safety and social security. In the current stage, several models are available for simulating and predicting the dispersion of hazardous gases to the surrounding environment, but these models all require information about the release source, for example, the release r...

Problem Statement Gas distribution modelling with a mobile robot in uncontrolled environments is a challenging field of research. This is mainly due to the chaotic nature of the dispersed gas that is affected by the turbulent features of the wind. We propose a statistical method to build two-dimensional gas distribution maps that takes into consideration the influence of wind in the dispersion ...
