Precision Optical Measurements of DNA Structure and Synthesis [PDF]

open access: yes, 2007
The structure and synthesis of DNA is important. Traditionally,high-resolution structures are solved with X-ray crystallography, and kinetic measurements are taken with consumption of large amount of reagents.

Kinetic‐Scale Turbulence in the Venusian Magnetosheath

open access: yesGeophysical Research Letters, 2021
While not specifically designed as a planetary mission, NASA's Parker Solar Probe (PSP) mission uses a series of Venus gravity assists (VGAs) in order to reduce its perihelion distance.

Parametric, Semiparametric, and Semi-Nonparametric Estimates of the Kinetic Energy of Ordered Air Motion and Wind Outliers in the Atmospheric Boundary Layer from Minisodar Measurements

open access: yesApplied Sciences, 2023
In the present work, we analyze the spatiotemporal dynamics of the kinetic wind energy with and without allowance for the kinetic energy of outliers. We first separated the contributions of the mean kinetic energy and the kinetic energy of the outliers ...

Kinetic measurements during transient film growth on zinc

open access: yesQuímica Nova, 2009
The electrochemical behaviour of zinc has been extensively studied in alkaline and acid media, but only a few studies have been reported in neutral solutions, particularly in deaerated media. Zinc passivation in neutral medium and the effect of the ClO4-

Kinetic oxygen measurements by CVC96 in L-929 cell cultures

open access: yesHead & Face Medicine, 2006
Generally animal and human cells use oxygen during their whole life. Consequently the oxygen use is a simple indicator to test the vitality of cells. When the vitality decreases by the delivery of toxic substances the decrease can be observed directly by

Performance Investigation of Currently Available Reaction Mechanisms in the Estimation of NO Measurements: A Comparative Study

open access: yesEnergies, 2023
Ammonia (NH3) has been receiving the attention of researchers as an alternative promising green fuel to replace fossil sources for energy production. However, the high NOx emissions are one of the drawbacks and restrictions of using NH3 on a broad scale.

Direct measurement of nitrous oxide kinetics [PDF]

open access: yesBritish Journal of Anaesthesia, 2012
Using conscious subjects, measurement of the effects of low concentrations of anaesthetic agents can allow the dynamics of onset and offset of the agent to be measured and kinetic values estimated. However, the tests have to be rapid and preferably assess cerebral function.We used a short version of the digit symbol substitution test (DSST) that ...

Dynamic 18F-FDG PET imaging of liver lesions: evaluation of a two-tissue compartment model with dual blood input function

open access: yesBMC Medical Imaging, 2021
Background Dynamic PET with kinetic modeling was reported to be potentially helpful in the assessment of hepatic malignancy. In this study, a kinetic modeling analysis was performed on hepatocellular carcinoma (HCC) and intrahepatic cholangiocarcinoma ...

Dual-tracer measurements of concentration profiles in the aqueous mass boundary layer [PDF]

open access: yes, 1995
A combination of two laser-induced fluorescence (LIF) techniques for measurements of vertical concentration profiles of dissolved gases and thus the investigation of micro-turbulence in the aqueous mass boundary layer at a free interface is presented ...
