Many Roma across Europe continue to face a range of social problems, including ethnic discrimination, marginalisation, residential segregation, socio‐economic inequality, and extremist violence. The lack of effective policies to address these issue

Surface- and guided-wave inversion for near-surface modeling in land and shallow marine seismic data
Publikováno v:
The Leading Edge. 32:638-646
In several domains of applied geophysics, surface, and guided waves are considered as a source of information for characterizing the near surface, which in a marine environment includes the seabed. By contrast, in exploration seismic surveys, these w

While in other domains of applied geophysics the surface-wave is considered a source of information for near-surface characterization, in the seismic industry the so-called ground roll has been traditionally regarded only as coherent noise to be filt

Standard procedures for dispersion analysis of surface waves use multichannel wavefield transforms. By using several receivers, such procedures integrate the information along the entire acquisition array. That approach improves data quality and robu

This paper describes a stereospecific synthesis of nine 2E,6E, 10(Z)-trienyl esters R1R2CCH(CH2)2CR3CH(CH2)2CR4CHCO2Me (1a-i) and their selective conversion into the corresponding epoxides (7a-i), including the natural occurring hormones JHI-III. The

α-Acetylenic epoxides,R′CCCR″CH2 (1), have been converted into α-allenic alcohols, RR′CCCR″-CH2OH (3), by means of a palladium(0)-promoted reaction with R-ZnCl (2; R: Me3Si(C≡C)n-(n=1 or 2), H2CCH- or t-BuCHCCH-). Using this method, an im

The reaction of alkylcopper(I) compounds, RCu, with 2,4-pentadiynyl methanesulfinates, R′CC-CCCR″R′″OS(O)Me (1), shows a regiochemistry that depends on the size of R, R′, R″ and R′″. If the group R′ is methyl or trimethylsilyl, the

Interaction between di(1-alkynyl) sulfides (1) and sodium sulfide, selenide or telluride in mixtures of liquid ammonia and methanol or dimethylformamide and methanol gives 1,4-dithiins (2), 1,4-thiaselenins (3) and 1,4-thiatellurins (4).
