Aiming to deduce the branching ratio of CH3CHO + OH, measurements were carried out in a shock tube by introducing deuterium into the chemical system. Overall rate coefficients for OH reactions with acetaldehyde (CH3CHO), acetaldehyde-2,2,2-d3 (CD3CHO), acetaldehyde-d4 (CD3CDO) were ...
NAPIER & SON, Ltd., D., HALFORD, F. B., and BARLOW, B. W. Nov. 6, 1940, Nos. 16156/40 and 14129/41. [Class 80 (ii)] The impeller A of a super-charger may be driven at three different speeds by means of gears K2, K3, K4 on a driving shaft K in constant mesh with ...
Remarkably, the Na2MoO2F4:Mn4+ phosphor with [MoO2F4] mixed-anion coordination exhibits a dominant luminescence peak at 625 nm (ascribed to the ZPL) and the ZPL to Stokes v6 intensity ratio reaches an unprecedented high value of 243% under 480 nm excitation. Density functional theory ...
The median value of NLR is 2.87 (range 0.02–14.33). In total, 77 and 52 patients were assigned to the NLR-low (≤3) and NLR-high (>3) groups, respectively. The two NLR groups had similar clinicopathological features (Table 1). Table 1. Clinicopathological characteristics of 129 patients...

Nondesorbed ethylene can be over-hydrogenated to form ethane [6,7]. In addition, ethylene selectivity also depends on the kinetics. Thus, for k2 >> k4, the desired ethylene products are obtained. For k1/k−1 >> k3/k−3, the adsorption of acetylene may prevent the readsorption of ...
The most direct way to improve the structural stiffness of multi-tower cable-stayed bridges is to increase the stiffness of the towers. Danish researchers believe that adequate longitudinal stiffness can be obtained with A-shaped towers, but this is not the only method [3,4]. The rigid middle...
On the other hand, preparative columns, especially those used for large-scale bioseparation (which have small bed-height to diameter ratios) and are packed with larger resin particles (>30 microns) do not [3,6]. While these columns can be loaded with large volumes of feed material, their ...
A suitable tool to characterize the spray formation is planar droplet sizing (PDS), as it allows for the determination of the droplet size (d) in terms of the Sauter mean diameter (SMD) over a plane defined by an illuminating laser sheet. The LIF/Mie ratio technique is based on the ...
The State-of-Health (SOH) of the batteries was estimated using the Weibull distribution function, which is found to be an appropriate formulation to use. Keywords: charge capacity decay; end of life; reliability; state of health; uncertainty; Weibull distribution function 1. Introduction Monitoring...
