Abstract We measure the spatially resolved recent star formation history (SFH) of M33 using optical images taken with Hubble Space Telescope as part Panchromatic Andromeda Treasury: Triangulum Extended Region (PHATTER) survey. The area covered by observations used in this analysis covers a de-projected ?38 kpc 2 and extends to ?3.5 ?2 from center along major semimajor axes, respectively. divide...

The morphology of the Milky Way is still a matter debate. In order to shed light on uncertainties surrounding structure Galaxy, in this paper, we study imprint spiral arms distribution and properties its molecular gas. To do so, take full advantage SEDIGISM survey that observed large area inner Galaxy $^{13}$CO(2-1) line at an angular resolution 28". We analyse influences by considering feature...

1. Hydrochloric acid extracts of Streptococcus haemolyticus contain type-specific, as well as non-type-specific, substances. The precipitates formed by these crude extracts with homologous antibacterial serum are flocculent, while those obtained with heterologous serum are usually disc-like. 2. The type-specific substance may be detected by the use of anti-bacterial sera absorbed with heterolog...

In contrast to non-cohesive sediments, the incipient motion of cohesive sediments is characterized by much more complex interactions between several sedimentary, biological, and chemical parameters. Thus, site-specific investigations are required to obtain information about the erosion stability of cohesive materials. This becomes even more relevant for contaminated sediments, stored in riverin...

We use hydrodynamical simulations to investigate the response of geometrically thin, self-gravitating, singular isothermal disks of gas to imposed rigidly rotating spiral potentials. By minimizing reflection-induced feedback from boundaries , and by restricting our attention to models where the swing parameter X ∼ 10, we minimize the swing amplification of global normal modes even in models whe...

Animal wastes are a major contributor of nutrients and enteric microorganisms to surface water and ground water. Polyacrylamide (PAM) mixtures are an effective flocculent, and we hypothesized that they would reduce transport of microorganisms in flowing water. After waste water running at 60.0 1 min(-1) flowed over PAM + Al2(SO4)3, or PAM + CaO in furrows, total coliform bacteria (TC) and fecal...

Spatial patterns in mercury cycling and bioaccumulation at the landscape level in the Everglades were investigated by collecting and analyzing multimedia samples for mercury species and biogeochemical characteristics from 228 randomly located stations. Higher total mercury (THg) in environmental compartments (surface water, soil, flocculent detrital material (floc), and periphyton) generally oc...

We and others have observed specialized regions of sarcoplasmic reticulum membranes that resemble coated vesicles, in the I-band region of myocardial cells. These structures have been named "corbular" sarcoplasmic reticulum, and are distinct in appearance from Golgi-associated coated vesicles, in that they are larger and contain a flocculent material that has been identified as calsequestrin. W...

B. megatherium phage, like staphylococcus phage, is inactivated by repeated high speed centrifugation (Northrop, 1938; Hotchin, 1954). This method of purification has the additional disadvantage that large volumes of material cannot be handled. B. megatkerium phage is precipitated from peptone solution by 0.4 saturated ammonium sulfate. The precipitate is filtered off, washed, and dissolved in ...

ABSTRACT The Milky Way spiral arms are well established from star counts as the locus of molecular clouds and other young objects; however, they have only recently started to be observed a kinematics point view. Using thin disc stars in Gaia EDR3 around extended solar neighbourhood, we create x–y projections coloured by radial, residual rotational, vertical Galactocentric velocities (U, ?V, W)....
