Identifying sediment sources in the tees catchment [PDF]

open access: yes, 2003
The main objective of this research is to identify the sources of suspended sediments in the River Tees. Earlier work in the Tees has focused on the extent of heavy metal concentrations in the river sediments as a result of mining m the upper catchment ...

Sediment accumulation expectations for growing desert cities: a realistic desired outcome to be used in constructing appropriately sized sediment storage of flood control structures

open access: yesEnvironmental Research Letters, 2019
Many rapidly urbanizing desert cities (RUDC) around the globe experience an acute risk of flooding. To reduce this risk, properly engineered flood control structures (FCS) must account for sediment accumulation as well as flood waters.

The Shewanella oneidensis Fic enzyme SoFic targets the switch‐I region of EF‐Tu for AMPylation

open access: yesFEBS Letters, EarlyView.
Fic enzymes mediate diverse post‐translational modifications across all domains of life, including AMPylation. Prokaryotic EF‐Tu can be AMPylated and deAMPylated by the conserved Fic enzyme SoFic. Structural and biochemical approaches were used to characterize the effect of AMPylation on EF‐Tu, SoFic's enzymatic activities, and the enzyme‐target ...

Chiral separation of chloroalkanes with the chromatographic column onboard Martian rovers

open access: yesFEBS Letters, EarlyView.
Computer image of the Rosalind Franklin Rover of ESA's ExoMars mission. ExoMars is scheduled to land on planet Mars in Oxia Planum in 2029. This area represents an interesting spot to look for biosignatures. Investigations of ExoMars include measurement on molecular chirality. We show that chiral chloroalkanes, that have been identified on Mars, can be

The Brigalow Catchment Study: VI.† Evaluation of the RUSLE and MUSLE models to assess the impact of clearing brigalow (Acacia harpophylla) on sediment yield

open access: yes, 2021
Land clearing for cropping and grazing has increased runoff and sediment yield in Central Queensland. The Brigalow Catchment Study (BCS), was established to determine the effect of land clearing on water balance, soils, and productivity, and consisted of

Effect of Slope Gradient on the Process of Runoff and Sediment Yield and Water-Sediment Relation on the Loess Slope

open access: yesShuitu baochi yanjiu, 2020
In order to explore the effect of slope gradient on erosion and water-sediment relationship on the loess slope under a rainfall event, simulated rainfall experiments were carried out in the laboratory, and the water-sediment relationship on the loess ...

Prospecting the protein design landscape

open access: yesFEBS Letters, EarlyView.
This review outlines the current state of various protein design approaches. We discuss the current possibilities enabled by recently released tools, highlight future avenues to pursue in protein design, and underscore the crucial role of key databases and resources for successful protein design workflows.

Hydrological factors influencing sediment concentration fluctuations in small drainage basins [PDF]

open access: yes, 1971
Although sediment concentrations measured in two contrasting streams in East Yorkshire fluctuate in response to similar hydrological factors, the effectiveness of these factors reflects the environmental characteristics of the drainage basins ...

The heterodimeric amino acid transporters (HAT) of the SLC7/SLC3 family: A structure−function relationships and relevance to human pathology

open access: yesFEBS Letters, EarlyView.
Heterodimeric amino acid transporters consist of SLC7 and SLC3 family proteins arranged in a conserved structural organization. They regulate nutrient transport across cell membranes, supporting essential cellular functions. These transporters also contribute to xenobiotic/drug uptake and distribution.

The Dynamics of Coarse Sediment Transfer in an Upland Bedrock River [PDF]

open access: yes, 2010
Bedrock channels in UK upland environments have received relatively little attention despite their importance within upland river systems and their influence on controlling the conveyance of sediment downstream. This thesis aims to quantify and model the
