Modeling hydrography and marine sedimentation in the Cariaco Basin since the Last Glacial Maximum [PDF]

open access: yes, 2009
The Cariaco Basin has shallow connections with the Caribbean Sea, and these are further reduced at times of lower sea level, such as at the Last Glacial Maximum (LGM).

Concentration Dependen Sedimentation of Collidal Rods

open access: yes, 2000
In the first part of this paper, an approximate theory is developed for the leading order concentration dependence of the sedimentation coefficient for rod-like colloids/polymers/macromolecules.

Dynamic stereo microscopy for studying particle sedimentation [PDF]

open access: yes, 2014
We demonstrate a new method for measuring the sedimentation of a single colloidal bead by using a combination of optical tweezers and a stereo microscope based on a spatial light modulator.

The sedimentation of flexible filaments

open access: yes, 2013
The dynamics of a flexible filament sedimenting in a viscous fluid are explored analytically and numerically. Compared to the well-studied case of sedimenting rigid rods, the introduction of filament compliance is shown to cause a significant alteration ...

Shear-induced sedimentation in yield stress fluids [PDF]

open access: yes, 2012
Stability of coarse particles against gravity is an important issue in dense suspensions (fresh concrete, foodstuff, etc.). On the one hand, it is known that they are stable at rest when the interstitial paste has a high enough yield stress; on the other

Adjunctive Therapeutic Plasma Exchange in Refractory Adult‐Onset Still's Disease Complicated by Secondary Macrophage Activation Syndrome: A Single‐Center Experience

open access: yesTherapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Introduction Adult‐onset Still's disease (AOSD) complicated by macrophage activation syndrome (MAS) carries substantial mortality. The role of therapeutic plasma exchange (TPE) remains uncertain. Methods We retrospectively analyzed patients with AOSD‐MAS treated with TPE at a single‐center.

The role of vegetation, drying, and rewetting on water and sediment phosphorus concentrations in an experimental ditch channel experiment

open access: yesAgrosystems, Geosciences & Environment
Intermittent drying and rewetting of agricultural drainage ditch networks along with vegetation presence play a significant role in phosphorus (P) fate and transport to the receiving water bodies.

In situ molecular organization and heterogeneity of the Legionella Dot/Icm T4SS

open access: yesFEBS Letters, EarlyView.
We present a nearly complete in situ model of the Legionella Dot/Icm type IV secretion system, revealing its central secretion channel and identifying new components. Using cryo‐electron tomography with AI‐based modeling, our work highlights the structure, variability, and mechanism of this complex nanomachine, advancing understanding of bacterial ...

Effects of flood conditions on lake water quality in an agricultural watershed with multiple conservation practices

open access: yesAgrosystems, Geosciences & Environment
This study measured 17 surface water quality (WQ) parameters in a 731 ha Conservation Effects Assessment Project watershed, Beasley Lake, in Mississippi, under varying flooding conditions from 2008 to 2022.

Discharge coefficient of vertical sluice gates with broad crested weir under free-submerged orifice flows using best subset regression

open access: yesWater Science and Technology
Accurate calculation of flow discharge for sluice gates is essential in irrigation, water supply, and structure safety. The measurement of discharge with the requirement of distinguishing flow regimes is not conducive to application.
