The 3850‐km long Deep Seismic Sounding profile QUARTZ crosses six major geologic provinces in Eurasia and is sourced by 3 nuclear 48 chemical explosions. We present the first interpretation of entire data set, using two dimensional (2‐D) ray tracing inversion, resolution analysis, 1‐D amplitude modeling. Our shows a 42‐km‐thick, high‐velocity crust under Baltic Shield, 29‐km‐thick upper mantle Mezenskaya depression, 52‐km‐thick with lower uppermost Urals, 40‐km‐thick West Siberian basin...
Lasing from HgCdTe microdisc cavities is demonstrated at wavelengths as long 22 — 25 μm. The optical threshold and operation temperature are far being limited by intrinsic recombination processes. employed ion etching technology appears to introduce additional defects in the vicinity of microdiscs, degrading figures merit height cavity increases. However, a watt-level mid-infrared pumping source should suffice for lasing microdiscs with moderate ~100 μm diameter.
Abstract The most prominent secondary phase observed in the records from ultralong profile “Quartz” crossing northern Eurasia is high-frequency long-range (teleseismic) Pn. This phase, propagating with group velocity of about 8.1 to 8.2 km/sec over 3000 km distances, dominates within frequency range above 5 Hz. Within this teleseismic Pn, we distinguish onsets several branches having higher apparent velocities between 8.5 and 8.6 km/sec. Using travel-time modeling techniques, associate Pn...
Frequency-dependent coda attenuation values are often reported; however, such measurements usually depend on the types of Q ( f ) models employed. We use numerical modeling peaceful nuclear explosion (PNE) at far-regional to teleseismic distances compare two models, namely, conventional frequency-dependent quality factor coda( )= η and frequency-independent c with geometrical γ ). The results favor strongly , model illustrate mechanisms leading apparent dependencies. Tests for variations...
Seismic reflection data show ∼40° S‐dipping reflectors that extend from the Cheyenne belt (CB‐Archean‐Proterozoic suture) to 20 km depths, and profound differences in crustal reflectivity across suture zone, which is itself imaged as an interwedging boundary. Archean crust has a Moho (at 40 km) abundant upper reflectivity; Proterozoic no distinctly less reflective. Reflective zones south of include 40° S‐ N‐dipping reflections Farwell Mountain zone depths; these are interpreted be complex...
Seismological monitoring of the Comprehensive Test Ban Treaty (CTBT) requires detailed knowledge travel-time characteristics seismic phases across large areas. We use first-arrival travel times from several Russian Deep Seismic Sounding (dss) profiles, primarily those Peaceful Nuclear Explosions (pnes), to construct a 3D regional model northern Eurasia. The method used, which can be viewed as generalization existing regionalization techniques, is based on apparent-velocity-based spatial...
The paper shows, that a low-temperature plasma initiated in liquid media interelectrode discharge gap is able to decompose hydrogen containing organic molecules resulting obtaining gaseous products with volume part of higher than 90% (up gas chromatography data). Tentative assessments energy efficiency, calculated regard for and feedstock heating value consumption, have shown efficiency factor 60-70%, depending on the source mixture composition. Theoretical model calculations current voltage...
Abstract A series of new polymerizable azo dyes containing the methacryloyloxy group were prepared. Their melting points, yield, colour, solubility and absorption in UV‐visible range characterized, relationship between their properties structure was evaluated. The characteristics radical homopolymerization one dyes, N‐methyl‐N‐[4‐(2,5‐dichlorophenyl) azophenyl]‐2‐aminoethyl methacrylate, its copolymerization with a number vinyl monomers determined. By using seeded polymerization dye...
A high-performance light-trapping structure for Si was fabricated with an etching margin of only ∼1 µm using Ge islands grown by gas-source molecular beam epitaxy as masks. KOH solution containing isopropyl alcohol and HF + H2O2 CH3COOH mixed were used etchants. The reflectance the shown to be comparable that a conventional pyramid texture, which requires larger ∼10 µm. In addition, potential short-circuit current density (p-Jsc) 42.3 mA/cm2 obtained sample after deposition indium tin oxide,...

Abstract Purification of liquids from undesirable admixtures and malignant bacteria is one the most important problems mankind. It especially sharply appeared at cleaning sewage. At present in part world (in densely populated territories) there a lack pure fresh water. Industrial domestic waste waters negatively influence on ecological situation stretches evident, that it caused by large quantity insufficiently cleaned sewage, which constantly comes to rivers ponds connection with...
Ключевой стадией термораспада гипофосфитов является реакция диспропорционирования, которая определяет фазовый состав и морфологию конечных продуктов. Отличительными особенностями гипофосфита аммония образование полифосфорной кислоты, а для продуктов всех рассмотренных – наличие красного фосфора. Реакции на воздухе характеризуются высокими значениями тепловыделения. The key stage of hypophosphite thermal decomposition is the disproportionation reaction, which determines phase composition and...
