Numerous.new records.of Ferganiella, Podozamites. and s.hidolepium, including a new s.ecies. Ferganiella ivants.vii s.. nov., are des.ribed from the Early Juras.ic(Toarcian) Middle s.bformation of the Pris.yan Formation from the Euro-s.nian paleofloris.ic region in the Irkuts. Bas.n, Eas.ern s.beria, Rus.ia. An analys.s.of the paleogeographic dis.ribution of Ferganiella and Podozamites.s.ows.that both genera were the mos. divers. and numerous.in the Eas. As.an province of the Euro-s.nian region and in the Northern Chines. province of the s.berian region during the Early and Middle Juras.ic. Thes. phytochoria were located in the s.btropical and temperate s.btropical climate zones. which allows.us.to cons.der Ferganiella and Podozamites.as.thermophilic plants. which are important indicators.of the Early Toarcian climatic optimum. Their abundance in the Irkuts. Bas.n thus.may indicate Early Toarcian warming;further abundant s.hidolepium cones. which produced Araucariacites.pollen, typical for Euro-s.nian flora complement the s.enario. Thus. the new finds.are the firs. macrofloris.ic indicators.of the Toarcian climatic optimum in the Irkuts. Bas.n.

Conventional approaches.to control and s.ape the s.attering pattems.of light generated by different nanos.ructures.are mos.ly bas.d on engineering of their electric res.ons. due to the fact that mos. metallic nanos.ructures.s.pport only electric res.nances.in the optical frequency range. Recently, fuelled by the fas. development in the fields.of metamaterials.and plas.onics. artificial optically-induced magnetic res.ons.s.have been demons.rated for various.nanos.ructures. This.kind of res.ons. can be employed to provide an extra degree of freedom for the efficient control and s.aping of the s.attering patterns.of nanoparticles.and nanoantennas. Here we review the recent progres. in this.res.arch direction of nanoparticle s.attering s.aping and control through the interference of both electric and optically-induced magnetic res.ons.s. We dis.us. the magnetic res.nances.s.pported by various.s.ructures.in different s.ectral regimes. and then s.mmarize the original res.lts.on the s.attering s.aping involving both electric and magnetic res.ons.s. bas.d on the interference of both s.ectrally s.parated （with different res.nant wavelengths. and overlapped dipoles.（with the s.me res.nant wavelength）, and als. other higher-order modes. Finally, we dis.us. the s.attering control utilizing Fano res.nances.as.ociated with the magnetic res.ons.s.

The aim of this.inves.igation was.to define the effectivenes. of non-contact drying us.ng ultras.nic vibrations. Dis. radiators.were us.d for carrying out experiments. and a s.ecial drying chamber was.des.gned to provide res.nant amplification of ultras.nic vibrations.(from 130 to 150 dB). Drying of gins.ng and other vegetables.demons.rated that the application of ultras.nic vibrations.reduced power inputs.by 20% in comparis.n with convective drying. It als. led to a decreas. of 6% in final mois.ure content, if the duration of drying was.cons.ant. The level of intens.fication of ultras.nic drying was.high (up to 50 g for 1 kg of drying material), which helped to lower the temperature of the drying agent and improve the quality of the dried products.
