Short wavelength free electron laser sources and science

Oct 23, 2017 · X ray free electron lasers (XFELs) are a remarkable development in the range of tools for scientific experimentation. They provide radiation with many orders of magnitude enhancement in brightness over other x ray sources, pulse durations down to a few femtoseconds, polarisation control, broad wavelength tunability and multi colour operation.

Vinyl acetate C4H6O2 PubChem

Two male Wistar Rats exposed to vinyl acetate (stabilized with 0.01% hydroquinone) concentrations varying between 200 and 2000 ppm in closed chambers with an exposure time of 1.4 hr or less demonstrated dose dependent elimination kinetics.The authors concluded that the metabolic pathways became saturated when vinyl acetate exposure levels exceeded 650 ppm (2320 mg/cu m).

N Nitrosodimethylamine (CH3)2NN=O PubChem

N Nitrosodimethylamine is a volatile, combustible, yellow, oily liquid nitrosamine with a faint characteristic odor that decomposes when exposed to light and emits toxic fumes of nitrogen oxides when heated to decomposition. N Nitrosodimethylamine is primarily used in laboratory research to induce tumors in experimental animals.

BG Validation of carbon isotope fractionation in algal

The headspace was measured, and average values and standard deviation errors reported are based on 6 measurements for June (3 at the high pCO 2 site and 3 at the control) and 36 measurements for September (3 each at the high pCO 2 site, mid pCO 2 site, and control, collected on four separate days).

Addressing Two Bottlenecks to Advance the Understanding

Although increasing efforts have gone into characterizing preferential flow in the past four decades, fundamental questions remain, as posed by Beven and Germann (1982), such as the initiation, dynamics, and persistence of preferential flow, and its dynamic interface with soil matrix (Beven and Germann, 2013; Jarvis, 2007).This is in part due to the lack of a conceptual foundation for the

The 23rd International Symposium on Cerebral Blood Flow

Inspired oxygen concentration (FiO2) was increased using high flow oxygen via a tight fitted face mask and end tidal carbon dioxide (EtCO2) was increased by adding carbon dioxide to the inspired gases. Measured variables were compared with baseline using non parametric ANOVA.
