Creep and fluidity of a real granular packing near jamming [PDF]
, 2011 We study the internal dynamical processes taking place in a granular packing below yield stress. At all packing fractions and down to vanishingly low applied shear, a logarithmic creep is evidenced. The experiments are analyzed under the scope of a visco-

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

FEBS Letters, EarlyView.Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative

Hematopoietic (stem) cells—The elixir of life?
FEBS Letters, EarlyView.The aging of HSCs (hematopoietic stem cells) and the blood system leads to the decline of other organs. Rejuvenating aged HSCs improves the function of the blood system, slowing the aging of the heart, kidney, brain, and liver, and the occurrence of age‐related diseases.

Nontrivial rheological exponents in sheared yield stress fluids
, 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

Yield and Environmental Stress
HortScience, 1988 Abstract Plant development is affected by physical stresses of all kinds. The most sensitive time is during anthesis and early fruit growth, when reproductive structures may fail to develop or embryos may abort. Water limitation can cause both effects, and explanatory theories are based on turgor, photosynthate availability, or hormonal relationships ...

Impact of water deficit stress in maize: Phenology and yield components
Scientific Reports, 2020 Fifteen million farmers in India engaged in Maize cultivation. India would require 45 MMT of Maize by 2022. But, only 15% of cultivated area of maize is under irrigation and water shortage has been a challenge for sustainability of maize production ...
