Geomorphological mapping of quarries

Visnyk of the Lviv University. Series Geography, 2016
Main issues related to the geomorphological mapping of quarries are discussed. The stages of creating these maps are characterized. The first stage is the analysis of raw materials and prefield mapping. The relief in contours with a relatively small value of horizontal crossing (2 m) is depicted in surveying and topographic maps and plans of mines ...

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

FEBS 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.

Mapping Wetland Types in Semiarid Floodplains: A Statistical Learning Approach

Remote Sensing, 2019
Detailed vegetation maps are needed for wetland conservation and restoration as different vegetation communities have distinct water requirements. It is a continuous challenge to map the distribution of different wetland types on a regional scale, and a ...

Low-cost mapping of coastal geomorphology by remote sensing in Angels Cove, Arraial do Cabo, Brazil

Revista Brasileira de Geomorfologia, 2023
Bathymetry is a crucial information for understanding coastal geomorphological processes. This study aims to evaluate the applicability of Satellite-Derived Bathymetry (SDB) as a low-cost alternative for coastal geomorphological mapping in Angels Cove ...

Residual tail twisting in ascidian larvae is stabilized by asymmetric myofibrils that resist bilateral symmetry restoration

FEBS Letters, EarlyView.
Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...

Geomorphological Mapping of Razzaza–Habbaria Area using Remote Sensing Techniques

, 2018
Landforms on the earth surface are so expensive to map or monitor. Remote Sensing observations from space platforms provide a synoptic view of terrain on images.

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

FEBS 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 ...

Geology and geodiversity of the Folafótur peninsula (Westfjords, Iceland)

Journal of Maps, 2023
Geological and geomorphological field surveys and mapping have been carried out in the Folafótur peninsula (Westfjords, Iceland), a remote territory characterized by spectacular landscapes resulting from the interaction of volcanic, tectonic, and glacial

Cell geometry and membrane protein crowding constrain Escherichia coli growth rate, overflow metabolism, respiration, and maintenance energy

FEBS Letters, EarlyView.
The physical dimensions and shape of bacterial cells define the surface area available to acquire nutrients and the volume available for synthesizing proteins and DNA. Here, we use computational systems biology to decode the importance of cell geometry as a major determinant of prokaryotic phenotype, including growth rate and metabolic efficiency. This

From mice to humans—divergent strategies for intestinal homeostasis and regeneration

FEBS Letters, EarlyView.
Recent advances such as organoid genome editing, xenotransplantation, imaging, and whole‐genome sequencing have enabled direct studies of human intestinal stem cells (ISCs). These studies reveal species‐specific features, including slower ISC proliferation, distinct injury responses, slower somatic mutation accumulation in humans, and an inverse ...
