Quantification of sediment transport through direct measurements and the use of empirical models in an experimental catchment in the Andes Mountains, Southern Chile.

Revista Técnica de la Facultad de Ingeniería, 2010
The quantification of sediment transport is very important in engineering studies and in the design of dams and bridges, but at the same time is one of the most difficult tasks to undertake.

Influence of chemical denudation on hillslope morphology [PDF]

, 2004
[1] Models of hillslope evolution involving diffusion-like sediment transport are conventionally presented as an equation in which the changes in land-surface elevation or soil thickness are balanced by the divergence of soil transport and tectonic ...

CDK11 inhibition induces cytoplasmic p21WAF1 splice variant by p53 stabilisation and SF3B1 inactivation

Molecular Oncology, EarlyView.
CDK11 inhibition stabilises the tumour suppressor p53 and triggers the production of an alternative p21WAF1 splice variant p21L, through the inactivation of the spliceosomal protein SF3B1. Unlike the canonical p21WAF1 protein, p21L is localised in the cytoplasm and has reduced cell cycle‐blocking activity.

Evaluating the Performance of Different Rainfall and Runoff Erosivity Factors—A Case Study of the Fu River Basin

Applied Sciences
The sediment yield resulting from storm erosion has become a focal point of research and a significant area of interest in the upper reaches of the Yangtze River amid changing environmental conditions. The issue of numerous types of erosivity factors (R)

Evaluation of the utility of sediment data in NASQAN (National Stream Quality Accounting Network) [PDF]

, 1983
Monthly suspended sediment discharge measurements, made by the USGS as part of the National Stream Quality Accounting Network (NASQAN), are analysed to assess the adequacy in terms of spatial coverage, temporal sampling frequency, accuracy of ...

Determining the Onset of Hydrodynamic Erosion in Turbulent Flow

, 2017
We revisit the longstanding question of the onset of sediment transport driven by a turbulent fluid flow via laboratory measurements. We use particle tracking velocimetry to quantify the fluid flow as well as the motion of individual grains.

Class IIa HDACs forced degradation allows resensitization of oxaliplatin‐resistant FBXW7‐mutated colorectal cancer

Molecular Oncology, EarlyView.
HDAC4 is degraded by the E3 ligase FBXW7. In colorectal cancer, FBXW7 mutations prevent HDAC4 degradation, leading to oxaliplatin resistance. Forced degradation of HDAC4 using a PROTAC compound restores drug sensitivity by resetting the super‐enhancer landscape, reprogramming the epigenetic state of FBXW7‐mutated cells to resemble oxaliplatin ...

Development of a distributed hydrological model combined with sediment transport calculations and its application to a medium-scale basin in northeast China

Environmental Research Communications
An accurate assessment of sediment transport can assist land and resource managers in any region. The primary objective of this study was to develop a distributed hydrological model for calculating rainfall-runoff coupled with sediment transport to ...
