Recombination Reactions as a Possible Mechanism of Mass-Independent Fractionation of Sulfur Isotopes in the Archean Atmosphere of Earth [PDF]
A hierarchy of isotopically substituted recombination reactions is formulated for production of sulfur allotropes in the anoxic atmosphere of Archean Earth.

Mechanical properties of tyramine substituted‐hyaluronan enriched fascia extracellular matrix [PDF]
AbstractNaturally occurring biomaterial scaffolds derived from extracellular matrix (ECM) have been the topic of recent investigation in the context of rotator cuff tendon repair. We previously reported a method to treat fascia ECM with high molecular weight tyramine substituted‐hyaluronan (TS‐HA) for use as a tendon augmentation scaffold. The presence

Application of gas wettability alteration to improve methane drainage performance: A case study
Hydraulic fracturing technique is widely used for methane drainage and has achieved good effects in numerous coal mines, but negative effects may occur as the fracturing fluids are absorbed into the coal seam.

Three-dimensional non-linear fracture mechanics by enriched meshfree methods without asymptotic enrichment [PDF]
This paper presents a three-dimensional, extrinsically enriched mesh-free method for initiation, growth and coalescence of an arbitrary number of cracks in non-linear solids including large deformations, for statics and dynamics.

A primordial origin for the atmospheric methane of Saturn's moon Titan [PDF]
The origin of Titan's atmospheric methane is a key issue for understanding the origin of the Saturnian satellite system. It has been proposed that serpentinization reactions in Titan's interior could lead to the formation of the observed methane ...

An astrophysically-relevant mechanism for amino acid enantiomer enrichment
The sublimation of low ee amino acids was examined while exploring simple mechanisms by which high ee amino acids can be generated under conditions that exist in space; significant enantioenrichment of a variety of amino acids by sublimation was achieved.

On the role of micro-inertia in enriched continuum mechanics [PDF]
In this paper, the role of gradient micro-inertia termsη¯∥ ∇u,t∥2and free micro-inertia termsη∥P,t∥2is investigated to unveil their respective effects on the dynamic behaviour of band-gap metamaterials. We show that the termη¯∥ ∇u,t∥2alone is only able to disclose relatively simplified dispersive behaviour.

Counterflow dielectrophoresis for trypanosome enrichment and detection in blood [PDF]
Human African trypanosomiasis or sleeping sickness is a deadly disease endemic in sub-Saharan Africa, caused by single-celled protozoan parasites. Although it has been targeted for elimination by 2020, this will only be realized if diagnosis can be ...

Lithium abundances along the RGB: FLAMES-GIRAFFE spectra of a large sample of low-mass Bulge stars [PDF]
Context: A small number of K-type giants on the red giant branch (RGB) is known to be very rich in lithium (Li). This fact is not accounted for by standard stellar evolution theory.
