The optical spectra of Seyfert galaxies are often dominated by emission lines excited both star formation and AGN activity. Standard calibrations (such as for the rate) not applicable to such composite (mixed) spectra. In this paper, we describe how integral field data can be used spectrally spatially separate associated with from accretion onto an active galactic nucleus (AGN). We demonstrate our method using two host (NGC 5728 NGC 7679) Siding Spring Southern Spectroscopic Snapshot Survey...
After more than a decade of electronic cigarette (E-cig) use in the United States, uncertainty persists regarding E-cig and long-term cardiopulmonary disease risk. As all E-cigs propylene glycol vegetable glycerin (PG-VG) generate abundant saturated aldehydes, mice were exposed by inhalation to PG-VG-derived aerosol, formaldehyde (FA), acetaldehyde (AA), or filtered air. Biomarkers exposure injury monitored mass spectrometry (urine metabolites), radiotelemetry (respiratory reflexes),...
A circular monopole antenna for ultra wideband (UWB) applications with triple band notches is proposed.The proposed rejects worldwide interoperability microwave access WiMAX (3.3 GHz-3.8GHz), wireless local area network WLAN (5.15 GHz-5.825GHz) and X-Band downlink satellite communication (7.1 GHz-7.9GHz).The utilises mushroomtype uniplanar Electromagnetic Band Gap (EBG) structures to achieve band-notched designs.The advantages of designs using EBG such as notch-frequency tuning, triple-notch...
Residential proximity to vegetation and plants is associated with many health benefits, including reduced risk of cardiovascular disease, diabetes mental stress. Although the mechanisms by which greenness affects remain unclear, have been shown remove particulate air pollution. However, association between residential-area exposure volatile organic chemicals (VOCs) has not investigated. We recruited a cohort 213 non-smoking individuals estimated peak, cumulative, contemporaneous greenery...
We present Wide Field Spectrograph integral field spectroscopy and Hubble Space Telescope Faint Object for the low-ionization nuclear emission line region (LINER) galaxy NGC 1052. infer presence of a turbulent accretion flow forming small-scale disk. find large-scale outflow ionization cone along minor axis galaxy. Part this is photoionized by active galactic nucleus shares properties with extended narrow-line Seyfert galaxies, but inner ('') disk around radio jet appear shock excited. The...
Here we describe the Siding Spring Southern Seyfert Spectroscopic Snapshot Survey (S7) and present results on 64 galaxies drawn from first data release. The S7 uses Wide Field Spectrograph mounted ANU 2.3 m telescope located at Observatory to deliver an integral field of 38 × 25 arcsec a spectral resolution R = 7000 in red (530–710 nm), 3000 blue (340–560 nm). From these cubes have extracted narrow-line region spectra 4 aperture centered nucleus. We also determine Hβ [O iii] λ5007 fluxes...
Ultra-wideband (UWB) disc monopole antenna with crescent shaped slot for double band-notched features is presented. Planned discards worldwide interoperability microwave access (WiMAX) band (3.3–3.6 GHz) and wireless local area network (WLAN) (5–6 GHz). Defected ground compact electromagnetic gap (DG-CEBG) designs are used to accomplish notches in WiMAX WLAN bands. planes utilised achieve compactness (EBG) structures. The proposed DG-CEBG show a of around 46% 50%, respectively, over mushroom...

Abstract A dual band-notched MIMO/Diversity antenna is proposed in this paper. The ensures notches WiMAX band (3.3–3.6 GHz) besides WLAN (5–6 GHz). Mushroom Electromagnetic Band Gap (EBG) arrangements are employed for discarding interfering frequencies. procedure followed to attain shape independent with established formulas. electromagnetic coupling among two narrowly set apart Ultra-Wide (UWB) monopoles reduced by means of decoupling bands and slotted ground plane. Monopoles 90° angularly...
ABSTRACT We investigate the relative significance of radiation pressure and gas in extended narrow line regions (ENLRs) four Seyfert galaxies from integral field Siding Spring Southern Spectroscopic Snapshot Survey (S7). demonstrate that there exist two distinct types starburst-active galactic nucleus (AGN) mixing curves on standard emission diagnostic diagrams, which reflect balance between ENLR. In ENLR is dominated throughout ionization parameter remains constant (log U ∼ 0). other...
Low frequency observations at 325 and 610 MHz have been carried out for two "radio-loud" Seyfert galaxies, NGC4235 NGC4594 (Sombrero galaxy), using the Giant Meterwave Radio Telescope (GMRT). The total intensity 325-610 spectral index images of tentatively suggest presence a "relic" radio lobe, most likely from previous episode AGN activity. This makes only second known galaxy after Mrk6 to show signatures episodic Spitzer Herschel infrared energy distribution (SED) modelling clumpyDREAM...
The present study was focused on the potentiality of agro-based residues for production pectinase to meet growing market demand by improving yield with low cost production.
