Reproducible mini-slump test procedure for measuring the yield stress of cementitious pastes

open access: yesMaterials Structure, 2017
The mini-slump test is a fast, inexpensive and widely adopted method for evaluating the workability of fresh cementitious pastes. However, this method lacks a standardised procedure for its experimental implementation, which is crucial to guarantee ...

An upstream open reading frame regulates expression of the mitochondrial protein Slm35 and mitophagy flux

open access: yesFEBS Letters, EarlyView.
This study reveals how the mitochondrial protein Slm35 is regulated in Saccharomyces cerevisiae. The authors identify stress‐responsive DNA elements and two upstream open reading frames (uORFs) in the 5′ untranslated region of SLM35. One uORF restricts translation, and its mutation increases Slm35 protein levels and mitophagy.

Effects of Water Stress on Photosynthesis, Yield, and Water Use Efficiency in Winter Wheat

open access: yesWater, 2020
Drought has become one of the major constraints to agricultural development, particularly in areas that lack water. Studying the effects of different water stresses on the photosynthesis, growth, yield, water use efficiency (WUE) and irrigation water ...

Cell wall target fragment discovery using a low‐cost, minimal fragment library

open access: yesFEBS Letters, EarlyView.
LoCoFrag100 is a fragment library made up of 100 different compounds. Similarity between the fragments is minimized and 10 different fragments are mixed into a single cocktail, which is soaked to protein crystals. These crystals are analysed by X‐ray crystallography, revealing the binding modes of the bound fragment ligands.

Rheological Characterization of Yield-Stress Materials: Flow Pattern and Apparent Wall Slip

open access: yesApplied Rheology, 2015
An experimental and numerical investigation of the rotational rheometry of yield-stress materials is performed, using waterbased Carbopol dispersions. The flow and fluid characterization in different rheometer geometries, namely the smooth Couette, the ...

Profile blunting and flow blockage in a yield stress fluid: A molecular dynamics study

open access: yes, 2008
The flow of a simple glass forming system (a 80:20 binary Lennard-Jones mixture) through a planar channel is studied via molecular dynamics simulations. The flow is driven by an external body force similar to gravity. Previous studies show that the model

Effects of high temperature stress during anthesis and grain filling periods on photosynthesis, lipids and grain yield in wheat

open access: yesBMC Plant Biology, 2020
Background Short episodes of high temperature (HT) stress during reproductive stages of development cause significant yield losses in wheat ( Triticum aestivum L.).

The (Glg)ABCs of cyanobacteria: modelling of glycogen synthesis and functional divergence of glycogen synthases in Synechocystis sp. PCC 6803

open access: yesFEBS Letters, EarlyView.
We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.

Effect of Different Bulk Sweeteners on the Dynamic Oscillatory and Shear Rheology of Chocolate

open access: yesApplied Rheology, 2017
Effect of different bulk sweeteners including maltitol, isomalt and inulin on the steady and dynamic rheological behaviors as well as chocolate structure was investigated.

Nontrivial rheological exponents in sheared yield stress fluids

open access: yes, 2017
In this work we discuss possible physical origins for non-trivial exponents in the athermal rheology of soft materials at low but finite driving rates. A key ingredient in our scenario is the presence of a self-consistent mechanical noise that stems from
