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

FEBS 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.

Dust to Dust

Population (French Edition), 1994
A ring of asteroidal dust encircles the Earth, and a cloud of dust permanently follows the Earth in its orbit around the Sun, according to new infrared satellite observations reported in the June 29 issue of Nature. The findings by astronomers at the University of Florida, Gainesville, may also help explain the asymmetry of the zodiacal cloud that ...

Breaking the Curve with CANDELS: A Bayesian Approach to Reveal the Non-Universality of the Dust-Attenuation Law at High Redshift [PDF]

, 2016
Dust attenuation affects nearly all observational aspects of galaxy evolution, yet very little is known about the form of the dust-attenuation law in the distant Universe.

Tau acetylation at K331 has limited impact on tau pathology in vivo

FEBS Letters, EarlyView.
We mapped tau post‐translational modifications in humanized MAPT knock‐in mice and in amyloid‐bearing double knock‐in mice. Acetylation within the repeat domain, particularly around K331, showed modest increases under amyloid pathology. To test functional relevance, we generated MAPTK331Q knock‐in mice.

How Do Martian Dust Devils Vary Throughout the Sol? [PDF]

, 2016
Dust devils are vortices of air made visible by entrained dust particles. Dust devils have been observed on Earth and captured in many Mars lander and orbiter images. Martian dust devils may be important to the global climate and are parameterised within

Genesis and evolution of dust in galaxies in the early Universe I. Modeling dust evolution in starburst galaxies

, 2011
We have developed a numerical galactic chemical evolution model. The model is constructed such that the effect of a wide range of parameters can be investigated.

Calpain small subunit homodimerization is robust and calcium‐independent

FEBS Letters, EarlyView.
Calpains dimerize via penta‐EF‐hand (PEF) domains. Using single‐molecule force spectroscopy, we measured the strength and kinetics of PEF–PEF homodimer binding. The interaction is robust, shows a transient conformational step before dissociation, and remains largely insensitive to Ca2+.

Prediction of coal dust particle size after spraying dust reduction in roadway based on orthogonal experiment and regression analysis

Meitan kexue jishu
In order to investigate the main factors affecting the effect of spray dust reduction on the particle size of coal dust after spray dust reduction, a quantitative mathematical model was obtained to characterize the quantitative relationship between the ...

The study of a severe dust storm over Persian Gulf, the Gulf of Oman and parts of the Indian Ocean with two operational dust forecasting models

Journal of Air Pollution and Health, 2022
Introduction: The entry of dust particles into water areas, which has increased sharply in recent years, causes a lot of environmental damage. The Persian Gulf and the Gulf of Oman are among the water areas that are covered with dust many times of the ...

Particle-size characteristics of the vertical dust profiles of two contrasting dust events in the Channel Country of western Queensland, Australia [PDF]

, 2006
Spatial and temporal variations in vegetation and soil surface conditions of rangelands add a level of complexity to wind erosion processes which is often difficult to model or measure.
