Terpenes are ubiquitous natural chemicals with diverse biological functions spanning all three domains of life. In specialized metabolism, the active sites of terpene synthases (TPSs) evolve in shape and reactivity to direct the biosynthesis of a myriad of chemotypes for organismal fitness. As most terpene biosynthesis mechanistically involves highly reactive carbocationic intermediates, the pr...

The European Standard EN 14105:2011-07 is an analysis method for quantifying free glycerol and residual mono-, di- and triacylglycerides impurities in biodiesel by gas chromatography. The method specifies an "on-column injector or equivalent device" as the means of sample introduction. Cool on-column (COC) would appear to be an ideal choice, particularly for quantifying triacylglycerides, as it...

We performed molecular dynamics simulation of nanoindentation on Cu/Ni nanotwinned multilayer films using a spherical indenter, aimed to investigate the effects of hetero-twin interface and twin thickness on hardness. We found that both twinning partial slip (TPS) and partial slip parallel with twin boundary (PSPTB) can reduce hardness and therefore should not be ignored when evaluating mechani...

Binding energy curves have been calculated for the ground-state rare-gas diatomics Ne(2) and Ar(2) and for the alkaline-earth diatomic Be(2) using the nonempirical density functionals from the first three rungs of a ladder of approximations: the local spin density (LSD) approximation, the Perdew-Burke-Ernzerhof (PBE) generalized gradient approximation (GGA), and the Tao-Perdew-Staroverov-Scuser...

The System Dynamics Characterization and Controls Laboratory of Sun Microsystems has developed novel continuous system telemetry technology for proactive fault monitoring and “electronic prognostics” capabilities for all types of executing computing platforms. Central to the goal of designing and evaluating prognostic and control systems for enterprise computing platforms is first the ability t...

Antimonene -- a single layer of antimony atoms and its few forms are among the latest additions to 2D mono-elemental materials family. Numerous predictions experimental evidence remarkable properties including (opto)electronic, energetic or biomedical, others, together with robustness under ambient conditions, have attracted attention scientific community. However, electrical is still lacking. ...

Background Patient satisfaction is an important part of quality care, and patient backgrounds can influence satisfaction with care. Since trauma disproportionately affects the underserved, this study aimed to determine the effects of race and insurance status on trauma patient satisfaction. Methods The validated Trauma Patient Satisfaction Survey (TPSS) was administered to 143 hospitalized trau...

The end-to-end delay is one of the most critical and fundamental issues for wireless sensor networks. Many applications of sensor networks require an end-to-end delay guarantee for time sensitive data. However, the end-to-end delay is difficult to bound for event-driven sensor networks, where nodes generate and propagate data only when an event of interest occurs, thereby producing unpredictabl...

<span lang="EN-US">Twelve-pulse rectification system had been widely integrated in today’s DC traction power sub-station (DC-TPSS). This configuration successfully mitigated low order harmonic distortion. As some research findings confirmed that the dc voltage and current ripple factors may further minimize by increasing number of pulses to 18, 24, or 36. paper presented a simulation stud...

BACKGROUND Independent external audits play an important role in quality assurance programme in radiation oncology. The audit supported by the IAEA in Serbia was designed to review the whole chain of activities in 3D conformal radiotherapy (3D-CRT) workflow, from patient data acquisition to treatment planning and dose delivery. The audit was based on the IAEA recommendations and focused on dosi...
