Effect of Standing Water on Formation of Fan‐Shaped Sedimentary Deposits at Hypanis Valles, Mars

open access: yesGeophysical Research Letters, 2023
Fan‐shaped sedimentary deposits are key indicators of paleoclimate on Mars. The largest example, a multi‐lobed deposit (>1,000 km2) at the outlet of Hypanis Valles, may have formed either subaerially or at the edge of a water body.

Epigenetic blind spots – the role of DNA methylation dynamics in stem cell‐based models of embryogenesis

open access: yesFEBS Letters, EarlyView.
Embryo‐like structures (stembryos) are an innovative tool, but they are hindered by experimental variability and limited developmental potential. DNA methylation is crucial for mammalian development, but its status in stembryo models is poorly characterized.

Fighting Through Community Participation Based on Vegetative Conservation Approach of Wonogiri Reservoir Sedimentation in Sub - Watershed of Keduang [PDF]

open access: yes, 2012
Humans are the main trigger factors causes of sedimentation. It’s happened because of the farming and cultivation system that is not based on the principles of sustainable development. These human activities causes in damage to the environment in the

Solution to Secondary Sedimentation Problem by Spreadsheet and VBA [PDF]

open access: yes, 2020
The sedimentation process is one of the most commonly used processes in environmental engineering. Modelling and simulation of secondary sedimentation units usually requires writing mass balance equations for each layer of the settler.

Sedimentation [PDF]

open access: yes, 2010
Sedimentation is a classic method of biochemistry that provides first‐principle hydrodynamic and thermodynamic information about the purity, size, shape, molar mass, association energy, association stoichiometry and thermodynamic nonideality of molecules

Geomorphological Study of formation and developments of Sand Ramps (Case study: Ebrahimabad Plain-Mehriz) [PDF]

open access: yesجغرافیا و توسعه, 2018
Sand Ramps is a kind of sedimentary accumulation found at the foot of the slopes of some desert and semi-desert region in the world. The landform unlike sand dune are complex that are created and developed by different processes.

Septin 9 PB domains coordinate centrosome positioning and microtubule acetylation to control epithelial polarity

open access: yesFEBS Letters, EarlyView.
Septin 9 polybasic domains couple phosphoinositide‐rich membrane binding to centrosome positioning, Golgi organization, and microtubule acetylation to control epithelial polarity. Their loss disrupts this axis, causing centrosome mispositioning, Golgi fragmentation, reduced microtubule acetylation, and polarity inversion via upregulation of the ...

Single Curved Fiber Sedimentation Under Gravity [PDF]

open access: yes, 2008
Dynamics of single curved fiber sedimentation under gravity are simulated by using the lattice Boltzmann method. The results of migration and rotation of the curved fiber at different Reynolds numbers are reported.

Solitary wave-induced 2D seepage effects on sediment incipient motion

open access: yesApplied Ocean Research
Solitary wave theory has been extensively applied to describe wave motions in very shallow water. Previous studies on sand movement induced by solitary waves have typically neglected the effects of seepage flow.

Quantitative Analysis of Hydro-Geomorphology Problems of the Likvan Chay Basin with Emphasis to Soil Erosion and Sedimentation (South - East of Ardebil) [PDF]

open access: yesجغرافیا و توسعه, 2009
The Likvan Chaybasin with 352.72 mm annually precipitation and 5.36% gradient is located on the south-east of Ardebil province. Based on the active tectonic (Bs=2.23), Vf=1.4 & 0.33) vast extension of potentially sensitive formation, impact, runoffs ...
