The aerosol extinction-to-backscatter ratio is an important parameter for inverting LIDAR signals in the LIDAR equation. It is a complicated function of the aerosol microphysical characteristics. In this paper, a method to retrieve the column-averaged aerosol extinction-to-backscatter ratio by constraining the aerosol optical depths (AOD) from a Micro-pulse LIDAR (MPL) by the AOD measurements f...

hydrogen peroxide is an important mild oxidant which is widely used in various applications including remediation of waste waters and drinking water resources. the safe level of h2o2 residue has to be controlled through accurate and precise measurement methods. a facile spectrophotometric method for the determination of hydrogen peroxide is based on the reaction of iodine solution with toluidin...

Introduction: This study investigates the effects of cannabinoid agonist WIN55-212-2 on acquisition and consolidation phases of the fear memory extinction and also on anxiety and motor activity. Methods: In this study, we used SPS & S model to induce post-traumatic stress disorder. One week after SPS, to establish a conditioned fear memory, rats received an electric foot shock within shock cha...

Transparent indium-doped ZnO thin films were deposited by the spray pyrolysis method onto glass substrates. The content of indium in the starting solution was 0.5 at. %. The crystallographic structure of the film was studied by X-ray diffraction (XRD). XRD measurement shows that the film is crystallized in the wurtzite phase and presents a preferential orientation along the c-axis. The texture ...

We show the existence of noncircular, self-similar solutions to the three-dimensional Hele-Shaw suction problem with surface tension regularisation up to complete extinction. In an appropriate scaling, these solutions are found as bifurcation solutions to a nonlocal elliptic equation of order three. The bifurcation parameter is the ratio of the suction speed and the surface tension coefficient....

Irradiation of the dinucleotide TpBU at all wavelengths from 240 to 295 m/u produces a debrominated photoproduct and two minor products. The main compound has an absorption maxi­ mum exactly at the same wavelength as the parent compound, but with approximately half the value of the extinction coefficient. It cannot be reverted by short wavelengths, such as 240 m/j,. Consistent with our observat...

A series of new organic D-pi-A dyes, A1, A2-H and A2-F, possessing a remarkably high absorption extinction coefficient of epsilon > 5.0 x 10(4) M(-1) cm(-1) at peak wavelength were synthesized, among which, A2-F having a key fluorine substitution attains excellent all solid-state DSSC performance, with optimized parameters of eta = 4.86%, J(SC) = 7.52 mA cm(-2), V(OC) = 0.91 V, and FF = 0.71.

A fluorescent compound 3,4-bis(2,4-difluorophenyl)-maleimide from the 3,4-diaryl-substituted maleimides was synthesized and determined to have a Stokes shift of 140 nm (λ(abs) 341 nm, λ(em) 481 nm), a high fluorescent quantum yield (Φ(fl) 0.61) and an extinction coefficient ε((340)) of 48 400 M(-1) cm(-1) in dichloromethane. For the first time we demonstrated the successful implementation of a...

This paper presents symbolic time series analysis of observable process variables for anomaly detection in thermal pulse combustors. The anomaly detection method has been tested on the time series data of pressure oscillations, generated from a non-linear dynamic model of a generic thermal pulse combustor. Results are presented to exemplify early detection of combustion instability due to reduc...

No. oltu1513 Beamline(s): X15A Introduction: The x-ray imaging technique, Diffraction Enhanced Imaging (DEI), has been used to independently visualize the refraction, absorption and extinction properties of an object. The image contrast is produced by thickness, density and/or composition changes of the sample. It was demonstrated that apparent absorption and refraction are not the only availab...
