We investigate the Hα and infrared star formation rate (SFR) diagnostics for galaxies in the Nearby Field Galaxy Survey (NFGS). For the 81 galaxies in our sample, we derive Hα fluxes (included here) from integrated spectra. There is a strong correlation between the ratio of far-infrared to optical luminosities L(FIR)/L(Hα) and the extinction E(B − V ) measured with the Balmer decrement. Before ...

OBJECTIVES We sought to determine which of the two main potential mechanisms underlying Thrombolysis In Myocardial Infarction flow grade 2 (TIMI-2 flow) operate in an individual patient who has had an acute myocardial infarction (AMI). BACKGROUND Systolic flow reversal (SFR) is a specific finding of capillary damage, the no-reflow phenomenon. The coronary blood flow velocity (CBFV) pattern of...

Background: Salivary flow rate (SFR), to estimate salivary gland dysfunction and radioactivity in different body fluids, to evaluate its intensity, were determined in thyroid patients after 131-I therapy. Material and Methods: For determination of SFR an innovative sponge test was adopted and the radioactivity in saliva, blood and serum of thyroid patients was determined by NaI (TI) Scintillati...

Recent observations of excited CO emission lines from z ∼ 2 disc galaxies have shed light on the SFR ∝ ρN relation at high z via observed SFR– COJ=2−1 and SFR– COJ=3−2 relations. Here, we describe a novel methodology for utilizing these observations of high-excitation CO to derive the underlying Schmidt (SFR∝ ρN) relationship. To do this requires an understanding of the potential effects of dif...

background and aims. change in the resting whole-mouth salivary flow rate (sfr) plays a significant role in pathogenesis of various oral conditions. factors such as smoking may affect sfr as well as the oral and dental health. the primary purpose of this study was to determine the effect of smoking on sfr, and oral and dental health. materials and methods. one-hundred smokers and 100 non-tobacc...

We investigate the [O II] emission-line as a star formation rate (SFR) indicator using integrated spectra of 97 galaxies from the Nearby Field Galaxies Survey (NFGS). The sample includes all Hubble types and contains SFRs ranging from 0.01 to 100 M⊙ yr . We compare the Kennicutt [O II] and Hα SFR calibrations and show that there are two significant effects which produce disagreement between SFR...

background: chewing sugar-free gums is a convenient way to increase salivary flow. salivary flow increases in response to both gustatory (taste) and mechanical (chewing) stimuli, and chewing gum can provide both of these stimuli. the aim of this study was to compare the effect of five different flavors of sugar-free chewing gum on the salivary flow rate (sfr) and ph. materials and methods: fift...

The anisotropies of cosmic far-infrared background (CFIRB) probe the star formation rate (SFR) of dusty star-forming galaxies as a function of dark matter halo mass and redshift. We explore how future CFIRB experiments can optimally improve the SFR constraints beyond the current measurements of Planck. We introduce a modelindependent, piecewise parametrization for SFR as a function of halo mass...

Young galactic X-ray point sources (XPs) closely trace the ongoing star formation in galaxies. From measured XP number counts we extract the collective 2-10 keV luminosity of young XPs, L x , which we use to gauge the current star-formation rate (SFR) in galaxies. We find that, for a sample of local star-forming galaxies (i.e., normal spirals and mild starbursts), L x correlates linearly with t...

We use data from the Hipparcos catalogue to construct colour-magnitude diagrams for the solar neighbourhood, which are then treated using advanced Bayesian analysis techniques to derive the star formation history, SFR(t), of this region over the last 3 Gyr. The method we use allows the recovery of the underlying SFR(t) without the need of assuming any a priori structure or condition on SFR(t), ...
