incoming RF signals to suppress a certain diffraction modes. The set of experimental verifications with two type AO modulators operating in Raman-Nath (hard flint cell) and Bragg (TeO2 cell) regimes have been performed. With use of the analogue third order polynomial RF synthesizer [2] there were obtained a rather good suppression of two-tone second-order intermodulations in space of the second...

Impairments in behavior and cognition are common in individuals diagnosed with fetal alcohol spectrum disorders (FASD). In this study, FASD model rats were intragastrically intubated with ethanol (5g/kg/day; 5E), sham-intubated (SI), or maintained as naïve controls (NC) over postnatal days (PD) 4-9. Ethanol exposure during this human third trimester-equivalent period induces persistent impairme...

2014 The 0.839 eV luminescence line in GaAs : Cr is generally interpreted as an internal transition in Cr2+ ion (5E-5T2) on gallium site. This interpretation does not agree with E.P.R. and far-infrared absorption results. White has proposed an interpretation as an excitonic recombination on an isoelectronic deep centre. We propose an alternative explanation in which the 0.839 eV line would be a...

5E-based science, technology, engineering, and mathematics (5E-STEM) education is known to be one of the most used pedagogical models in STEM-oriented science courses for middle school students. However, 5E model lacks a clear explanation how STEM subjects are strongly linked each its operational “E”. In this study, novel approach was proposed with use argumentation-supported 5E-STEM (A-5E-STEM...

In the title mol-ecule, C(15)H(12)O(3), the three five-membered rings are nearly coplanar: the dihedral angles between the cyclopentanone ring and the furan rings are 3.5 (2) and 9.7 (2)°, and the two furan rings form a dihedral angle of 7.2 (2)°. In the crystal structure, weak inter-molecular C-H⋯O hydrogen bonds help to consolidate the crystal packing.

OBJECTIVE This study is designed to explore permeability of ethosomes encapsulated with 5-florouracil (5-FU) mediated by CO2 fractional laser on hypertrophic scar tissues. Moreover, therapeutic and duration effect of CO2 fractional laser combined with 5-FU encapsulated ethosomes in rabbit ear hypertrophic scar model will be evaluated. METHODS The permeated amount of 5-FU and retention content...

as a continuous research for discovery of new cox-2 inhibitors, chemical synthesis, in vitro biological activity and molecular docking study of anew group of 1,4-dihydropyridine (dhp) derivatives were presented. novel synthesized compounds possessing a cox-2 so2me pharmacophore at the para position of c-4 phenyl ring, different hydrophobic groups (r1) at c-2 position and alkoxycarbonyl groups (...
