of analysis.22 This is because the intervention is not clean. A RRS is It is hard to think of an intervention in the last two decades hat has been implemented in such a widespread fashion, and so ffectively, but with so little evidence as Rapid Response Systems.1 o one from an administrative, clinical or research perspective can uestion the underlying assumptions that underpin RRS utilizaion. A...
Secchi disk depth (ZSD) is used to quantify water clarity as an important water-quality parameter, and one of the most mechanistic models for ZSD quasi-analytical algorithm (QAA), which latest version QAA_v6. There are two in QAA clear turbid waters (referred QAA_clear QAA_turbid). QAA_v6 switches between by setting a threshold value remote sensing reflectance (Rrs, sr−1) at selected reference ...
In recent years, ultraviolet (UV) bands have received increasing attention from the ocean colour remote sensing community, as they may contribute to improving atmospheric correction and inherent optical properties (IOPs) retrieval. However, most satellite sensors do not UV bands, accurate retrieval of reflectance (Rrs) data is still a challenge. order address this problem, study proposes hybrid...
An A1400G mutation of the rrs gene was identified in Mycobacterium tuberculosis (MTB) strain ATCC 35827 and in 13 MTB clinical isolates resistant to amikacin-kanamycin (MICs, >128 microg/ml). High-level cross-resistance may result from such a mutation since MTB has a single copy of the rrs gene. Another mechanism(s) may account for high-level amikacin-kanamycin resistance in two mutants and low...
The interaction of Methylene Blue (MB) with chondroitin-4-sulfate (CHS) has been investigated using spectroscopic techniques, including UV-Vis absorption, Rayleigh resonance scattering (RRS), and circular dichroism (CD). The addition of CHS caused a decrease in the absorbance of MB at 664 nm with a new absorption band appearing at 570 nm, enhanced RRS at 314 nm and 560 nm, and also resulted in ...
The increasing penetration of variable energy resources in modern electric power systems requires additional flexibility in ancillary service provision to maintain reliable and efficient grid operations. However, full recognition and appropriate compensation of this flexibility is difficult to ensure within current power market designs due to rigidities in service definitions and requirements. ...
Dynamic distributed computing environments are composed by various entities, which, seeking for the maximization of their welfare while achieving their own goals and aims, may act selfishly, thus, leading to a significant deterioration of system’s performance. In general, system entities may be classified into two main categories: the Resource Requestors (RRs) wishing to use and/or exploit reso...
A CE-resonance Raman spectroscopy (CE-RRS) method based on MEKC and sweeping-MEKC modes is described. A nonfluorescent compound, malachite green (MG), and a doubled Nd:YAG laser (532 nm, 300 mW) were selected as model compound and light source, respectively. In order to carry out a quantitative analysis of MG, a monochromator (effective bandwidth, 0.4 nm) was used to collect the specific Raman ...
Mutations causing resistance to aminoglycosides, such as kanamycin (KAN), amikacin (AMK), and streptomycin, are not completely understood. In this study, polymorphisms of aminoglycoside resistance influencing genes such as rrs, eis, rpsL, and gidB in 41 drug-resistant and 17 pan-sensitive Mycobacterium tuberculosis clinical isolates in Latvia were analyzed. Mutation A1400G in rrs gene was detec...
We studied the electronic energies and phonon frequencies of polydiacetylene 4-BCMU thin films at high pressures up to 50 kbar using Raman scattering under preresonant and resonant conditions. Pressure-induced changes in the resonant Raman scattering (RRS) include (1) hardening of the most strongly coupled phonon frequencies, (2) dispersion of the RRS frequencies with the laser excitation coL, ...
