On The Linearity of The Black Hole - Bulge Mass Relation in Active and in Nearby Galaxies

Analysis of PG quasar observations suggests a nonlinear relation between the black hole mass, M_BH, and the bulge mass, M_bulge, although a linear relation, as proposed for nearby galaxies, cannot be ruled out. New M_BH values for nearby galaxies from Gebhardt et al., and L_bulge measurements for Seyfert 1 galaxies from Virani et al., are used here to obtain a more accurate value for the slope of the M_BH-M_bulge relation. The combined sample of 40 active and non-active galaxies suggests a significantly nonlinear relation, M_BH\propto M_bulge^{1.53\pm 0.14}. Further support for a nonlinear relation is provided by the slope of the M_BH-stellar velocity dispersion relation found recently, and by the low M_BH found in late type spiral galaxies. The mean M_BH/M_bulge ratio is therefore not a universal constant, but rather drops from ~0.5% in bright (M_V ~ -22) ellipticals, to ~0.05% in low luminosity (M_V ~ -18) bulges. Hubble Space Telescope determinations of M_BH in late type spirals, and of the bulge magnitude in narrow line Seyfert 1 galaxies (both predicted to have low M_BH), can further test the validity of the nonlinear M_BH-M_bulge relation.Comment: Accepted for publication in ApJ, 9 pages inc. 2 figure

Combination of Tempeh and Carrot Prevent Atherosclerosis Wistar Rat: Indicated by Increase of Hdl and Total Antioxidant, Decrease Ldl, F2-isoprostan, and Il-6

Coronary heart disease (CHD) is the leading cause of death, either in developed and developing countries. The disease is stimulated by the present of atherosclerosis. This study aims to investigate supplementation of combined tempeh M-2 and carrot to prevent atherosclerosis wistar rat by increases HDL and TAC, decreases LDL, F2-Isoprostan, and IL-6. This was a true experimental study with the factorial completely randomized post-test only control group design. variables such as KN (standard feeding / pellets (50 g / kg bw / day), KP: pig lubrication: pellets (1: 9) (50 g / kg bw / day), T : lubrication pig: pellets (1: 9) with tempeh M -2 (20 g / kg bw / day), W: pig lubrication: pellets (1: 9) with carrots (20 g / kg bw / day), and TW: pig lubrication: pellets (1: 9) with tempeh M-2 (20 g / kg bw / day), and carrots (20 g / kg bw / day). Dependent variables in this study are serum HDL,serum TAC, LDL serum, urine F2-Isoprostan, and plasma IL-6 (with Elisa Method).

Plastics consists of artificial inorganic materials are very difficult to be described in a natural. Therefore, its use can be said to be harmful to the environment when used as an example of excessive plastic waste polluting the rivers, beaches, forests, and so forth. In addition, plastic waste has diversity in terms of shape and properties such as transparency, dry and wet. Based on that the creators are interested in lifting the plastic waste into works of art with the theme "Waste Plastics in Environmental Phenomena" which means, the depiction of the synthetic waste material and its relationship with the area around both the reality and impact surrounding negatife, to further express how the creator object trash plastics, process engineering, composing elements of art and can capture the message and its relation to the phenomenon of the surrounding environment, so as to provide benefits to the creators, society and institutions. In realizing the ideas and themes of the paintings, through the assessment process, trial, preparation, formation and final settlement. In the creation of works of art, organizing elements and elements of art are combined with appropriate technical capabilities occupied during the learning process, with the application of color to achieve the character and atmosphere of the work embodied in realistic. The impression that is achieved is a light, solid, natural, characteristics and spatial impression and show object details on each paper. Applied to the plaque technique, block and dry using oil paint with a brush, do a thorough step by step, in order to create an object characteristic of plastic waste and other supporting objects. In the embodiment of the object, expressed through ideas and imagination, so as to represent the plastic trash and circumstances into paintings. Thus through ten works under cultivation, can represent plastic waste and environmental situation, which is revealed in a naturalistic, realistic, and metaphorically, through it can be created meaning communicative and able soulful creator in hopes audience felt the same way.

Topological phase transitions in the repulsively interacting Haldane-Hubbard model

Using dynamical mean-field theory and exact diagonalization we study the phase diagram of the repulsive Haldane-Hubbard model, varying the interaction strength and the sublattice potential difference. In addition to the quantum Hall phase with Chern number $C=2$ and the band insulator with $C=0$ present already in the noninteracting model, the system also exhibits a $C=0$ Mott insulating phase, and a $C=1$ quantum Hall phase. We explain the latter phase by a spontaneous symmetry breaking where one of the spin-components is in the Hall state and the other in the band insulating state.Comment: Updated version, 6 pages, 4 figure

Orbital magnetoelectric coupling in band insulators

Magnetoelectric responses are a fundamental characteristic of materials that break time-reversal and inversion symmetries (notably multiferroics) and, remarkably, of "topological insulators" in which those symmetries are unbroken. Previous work has shown how to compute spin and lattice contributions to the magnetoelectric tensor. Here we solve the problem of orbital contributions by computing the frozen-lattice electronic polarization induced by a magnetic field. One part of this response (the "Chern-Simons term") can appear even in time-reversal-symmetric materials and has been previously shown to be quantized in topological insulators. In general materials there are additional orbital contributions to all parts of the magnetoelectric tensor; these vanish in topological insulators by symmetry and also vanish in several simplified models without time-reversal and inversion those magnetoelectric couplings were studied before. We give two derivations of the response formula, one based on a uniform magnetic field and one based on extrapolation of a long-wavelength magnetic field, and discuss some of the consequences of this formula.Comment: 13 page

Piezoelectric copolymer hydrophones for ultrasonic field characterization

Hydrophones to be used in the characterization of medical ultrasonic transducers have been fabricated using a new polyvinylidene fluoride/trifluoroethylene (VF2/VF3) copolymer. The copolymer has an advantage over VF2 in that it does not require prestretching before poling. Thin copolymer films can be cast from solution and then poled using the corona discharge method. As there is a need for small‐diameter hydrophones to provide good spatial resolution in measuring highly focused ultrasonic beams, hydrophones with diameter as small as 0.1 mm have been made. Both needle‐type and line hydrophones have been tested and their performance reported. In the case of line hydrophones, the output signal is proportional to the line integral of the acoustic pressure and a computer tomographic technique has been used to reconstruct the beam profiles
