Numerical program for analysis of three-dimensional supersonic exhaust flow fields (CHAR 3D)

Choice of reference plane orientation depends on specific nozzle geometry, with different configurations requiring different reference plane systems. In addition, for given configuration several reference systems may be used in different regions of flow field, so each system is locally aligned with flow

MANASIKA VEGAS: THEIR CAUSES, EFFECTS AND PSYCHO SPIRITUAL TREATMENT

Manasika Vega is the intensification of Dharaniya Vega Kama, Krodha, Lobha, Mada, Matsarya, etc. This happens due to the intensification of Raga and Dvesha, which is triggered by the vitiation of Rajas and Tamas due to Asatmyaendriyartha Samyoga, Prajnaparadha and Parinama. When Raga and Dvesha get intensified, it leads to strengthening of desires, which in turn leads to a series of associated emotions of anger, fear, greed, delusion, etc. Scriptures identify Manasika Vega as a disease in themselves because they affect the functioning and health of the mind when left unchecked and divert the mind from the purpose of life which is the pursuit of the fourfold goals of Dharma, Artha, Kama and Moksha. As a result, they cause an imbalance in the three legs of life body, mind and soul, leading to physiological diseases, psychological diseases and Vasanas, that are the impressions from previous births which affects health as well. Therefore, Ayurvedic and Allied Scriptures recommend addressing the root cause, controlling the senses, cleaning the mind and the intellect through lifestyle modification, diet and psycho spiritual practices. These practices are listed in several different scriptures at philosophical and practical levels and need regular practice to have an effect. With regular practice aimed at restoring Sattva, the third Guna that is considered the purest, Rajas and Tamas can be destroyed, leading to detachment to sensorial pleasures and a steady, well-regulated and healthy mind

Evidence of 1D behaviour of He4^4 confined within carbon-nanotube bundles

We present the first low-temperature thermodynamic investigation of the controlled physisorption of He$^{4}$ gas in carbon single-wall nanotube (SWNT) samples. The vibrational specific heat measured between 100 mK and 6 K demonstrates an extreme sensitivity to outgassing conditions. For bundles with a few number of NTs the extra contribution to the specific heat, C$_{ads}$, originating from adsorbed He$^{4}$ at very low density displays 1D behavior, typical for He atoms localized within linear channels as grooves and interstitials, for the first time evidenced. For larger bundles, C$_{ads}$ recovers the 2D behaviour akin to the case of He$^{4}$ films on planar substrates (grafoil).Comment: 4 pages, 3 figures, submitted to Phys. Rev. Let

Nonequilibrium fluctuation-dissipation relations for one- and two-particle correlation functions in steady-state quantum transport

We study the non-equilibrium (NE) fluctuation-dissipation (FD) relations in the context of quantum thermoelectric transport through a two-terminal nanodevice in the steady-state. The FD relations for the one- and two-particle correlation functions are derived for a model of the central region consisting of a single electron level. Explicit expressions for the FD relations of the Green's functions (one-particle correlations) are provided. The FD relations for the current-current and charge-charge (two-particle) correlations are calculated numerically. We use self-consistent NE Green's functions calculations to treat the system in the absence and in the presence of interaction (electron-phonon) in the central region. We show that, for this model, there is no single universal FD theorem for the NE steady state. There are different FD relations for each different class of problems. We find that the FD relations for the one-particle correlation function are strongly dependent on both the NE conditions and the interactions, while the FD relations of the current-current correlation function are much less dependent on the interaction. The latter property suggests interesting applications for single-molecule and other nanoscale transport experiments.Comment: This revised version is now accepted for publication in the Journal of Chemical Physics (March 2014). arXiv admin note: text overlap with arXiv:1305.507

Non-Collinear Ferromagnetic Luttinger Liquids

The presence of electron-electron interactions in one dimension profoundly changes the properties of a system. The separation of charge and spin degrees of freedom is just one example. We consider what happens when a system consisting of a ferromagnetic region of non-collinearity, i.e. a domain wall, is coupled to interacting electrons in one-dimension (more specifically a Luttinger liquid). The ferromagnetism breaks spin charge separation and the presence of the domain wall introduces a spin dependent scatterer into the problem. The absence of spin charge separation and the effects of the electron correlations results in very different behaviour for the excitations in the system and for spin-transfer-torque effects in this model.Comment: 6 pages, submitted to Journal of Physics: Conference Series for JEMS 201
