The problem of gas slip at a plane wall is solved on the basis of a linearized kinetic equation with a model collisional term (the S-model, which provides the correct value of the Prandtl number).
      
These effects make it possible to explain the broadening of the spectrum, the stable distribution of the visualization pattern, and the appearance of irregularities in the oscillograms observed in the S transition.
      
The additional photoluminescence band with a maximum in the range of 440 nm at 10 K is assigned to the transition B""3Πu → X3Σg- in the S2 molecule.
      
The particle size decreases with an increase in the S/Au ratio.
      
It was shown that isomerization and substitution of the methoxy group do not lead to significant enhancement of the S-T transition.
      
Competition between photoinduced electron transfer from the S2 level of tryptophan to Eu(III) and the S2 → S1 internal conversio
      
It was shown that in the S0 state, the azide group in all the azides has quasi-linear geometry and a significant positive charge on the two terminal nitrogen atoms.
      
As a result, the σNN* orbital is not populated in the S1 state when a particular threshold size of the π system is achieved, and the azide becomes photo-inactive.
      
The appearance of the S2 level near the S1 level in the scheme of the energy states of symmetrically substituted DCM (bis-DCM) causes changes in photophysical processes and a drop in the fluorescence quantum yield.
      
The σNN* antibonding orbital at the N-N2 bond was occupied in both of the azides in the S1 state; this fact is consistent with the photochemical activity of these compounds.
      
It was shown that the σNN* molecular orbital, which is localized on the azide group and is antibonding for the N-N2 bond, is populated in the S1 state of these azides in both neutral and protonated forms.
      
The formation of dimers is manifested by two absorption bands of different intensities due to splitting of the S* level of the monomers upon their resonance interaction.
      
Some differences are observed only downstream of the inflection point of the S-shaped walls, where a velocity profile with two-way downwash is realized.
      
According to this relationship, the ECG signal is represented as a sum of the first time derivatives of the TAPs of atrial and ventricular myocardial cells, with the segment from the S wave to the end of the T wave inverted.
      
The parameters of an ST-10XME CCD camera incorporated in the S180 spectrometer have been studied, and a mathematical model describing its characteristics has been developed.
      
A system of triggers has been developed for selection of events with η-mesic nuclei, which are identified by a two-particle decay of the S11(1535) resonance produced in a target nucleus (S11 → pπ-).
      
Binding experiments showed that the S-naproxen imprinted polymer had better recognition capability for the template than that of a blank polymer.
      
The quenching mechanism was studied and the results suggested that both dynamic and static quenching processes were responsible for the observed positive deviation in the S-V plot.
      
The formation of surface sulfite at T ≥ 473 K (the S 2p3/2 binding energy (Eb) is 167.5 eV) and surface sulfate at T ??≥? 573 K (Eb = 169.2 eV) was observed in the reactions of Al2O3 and CeO2 with SO2.
      
At T ≤ 200°C, dimethyl disulfide undergoes hydrogenolysis at the S-S bond, yielding methanethiol in 95-100% yield.
