Study of stimulation impedance myography contractions predictive indicators in occlusion lesions of lower extremities vessels

As a predictive indicator of tissue viability in multiple muscle lesions used the percentage of high-, medium- and low amplitude contracting reactions (СR) or their absence, recorded by stimulation impedance myography contraction (SIMC). After examining the boundaries of the scattering of amp-omic muscle curves of the limbs, the patients determined the distribution of maximum contractile reactions (MSRs) by the angles of tilt curves in the coordinate plane. After examining the boundaries of the scattering of amp-omic muscle curves of the limbs, the patients determined the distribution of maximum contractile reactions (MCRs) by the angles of tilt curves in the coordinate plane. Average sectoral values of MSR were distributed in reverse dependence of amplitudes on the amount of stimulus in the form of hyperbole containing high-, medium-, and low-amplitude MSD, the percentage of which were based on the profiles of histograms of patients with known clinical diagnoses. Comparison of histogram profiles of different stages of chronic ischemic syndrome among themselves showed their high distinguishing ability and correlation of histograms with diagnoses.

Geographical Distribution of Catering Venues and the Importance of Geographical Factor for Customer Satisfaction

To date Russian market of catering services is experiencing serious difficulty: there is a significant fall in visitors’ inflow in all market segments, except the fast-food segment. The decline in the number of visits is mostly caused by the economic downturn in the country which brings about the decline in population real income. As a result, there is a growing tendency for budget saving, switching to cheaper substitutes, or even abandoning the consumption of certain goods, such as visiting traditional restaurants. This leads to shrinking catering venues. But despite the hard times, some restaurateurs continue to open new venues, many of which are becoming successful. All successful institutions have much in common: specialized or unusual concept of the venue or advantageous location, with most new restaurants being opened in the centre of Moscow. The author finds it important to correlate the restaurant’s location with the system of visitor’s satisfaction. As a result, the author segments the consumers by the location factor and reveals the reverse dependence in restaurant location and place of residence.

Correlation Between Hsp90 Induction Kinetics In Murine Leukemia Cells And The Amount Of Cisplatin Over A Wide Range Of Cytostatic Concentrations

The induction of HSP90 in murine erythroleukemia cells, clone F4 N, by cisplatin (DDP) was examined using indirect immunofluorescence and avidin-biotin technique, and compared with cisplatin cytotoxicity. A reverse dependence of HSP90 induction time was found on a wide range of cisplatin concentrations (0.5D10 μᴍ), which proved to be cytostatic up to 48 h of continuous treatment. Thus, the observed induction pattern of HSP90 in F4 N cells strictly correlated with their high tolerance toward DDP. This indicates that HSP90 might be responsible, at least in part, for cisplatin resistance of F4 N cells

Reverse Dependence of Ge Surface Segregation on Growth Temperature in Si-Mbe

ABSTRACTGe surface segregation on Si(100) and Si(111) substrates during silicon molecular beam epitaxy is studied as a function of growth temperature. During growth, the Ge atoms are partly incorporated into the growing layer and the residuals segregate on the grown surface. The incorporation coefficient cannot be expressed in terms of a simple thermal activation process. That is, the Ge segregation phenomena increase to maxima at around 450°C for the Si(100) substrates and at around 650°C for the Si(111) substrates. Segregation decreases above these temperatures. These reverse temperature dependences enable not only good crystallinity of the heteroepitaxial layer, but also abrupt heterointerfaces. The incorporation coefficients for Si(111) are much larger than those for Si(100), which is explained by a model based on surface migration.

Passivation of Nickel Monocrystal Surfaces

Steady state potentiostatic polarization measurements on low index nickel monocrystal surfaces in 1N H2SO4 indicate a strong anisotropy in passive current densities. The nature of this orientation dependence appears to be related to such properties of the solid state as the crystal growth axis. For example, in the case of crystal growth parallel to the 〈110〉 axis, the degree of protection provided by the passive film on a {111} surface is greater than that on either {110} or {100} faces, i.e., the passive current densities are in the following order: {111}<{110}<{100}. It is interesting to note than an identical anisotropy has been reported in the rates of gaseous oxidation on nickel surfaces. On the other hand, precisely the reverse dependence is observed in passivation studies when the growth direction of the monocrystal is parallel to the 〈100〉 axis. The above results are examined in terms of the crystallography and defect structure of the film, the metal/film interface, and the metal substrate and their relevance to current theories of passivation is considered.

The effect on a tarnishing reaction of an electric field across the growing product layer

A study has been made of the effect of an applied electric field on the rate of oxidation of zinc and tungsten. An applied potential was established across the growing oxide layer by means of an inert porous platinum electrode at the gas/oxide surface. It was shown that for zinc at 350 °C and below, and for tungsten at 170 °C the direction of the effect was such that a reduction in the rate of oxidation resulted from a potential polarity with the porous platinum negative with respect to the metal substrate. For zinc at 390 °C and for tungsten at 260 °C the reverse dependence on polarity was observed. It was concluded that at 350 °C and below with zinc and at 170 °C with tungsten electron transport was rate-controlling, while with zinc at 390 °C and with tungsten at 260 °C mass transport was rate controlling. From a comparison with the known oxidation kinetics of these metals, it was suggested that these transitions in rate controlling species were accompanied by transitions from logarithmic to parabolic growth laws.
