Romanov Emmanuel Institute of Biochemical Physics Russian Academy of Sciences Moscow Russia imiryazev Institute of Plant Physi- ology Russian Academy of Sciences Moscow Russia Timiryazev Institute of Plant Physi- ology Russian Academy of Sciences Moscow Russia Timiryazev Institute of Plant Physi- ology Russian Academy of Sciences Moscow Russia Laboratory of Plant Physiology Wageningen University Wageningen The Netherlands.

Wild-type potato (Solanum tuberosum L.) plants and their transformants harboring agrobacterial rolB or rolC genes under control of the patatin class I promoter were cultured in vitro. These plants were used as a source of single-node stem cuttings. The structure of native starch in tubers formed on cuttings was determined using methods of X-ray scattering and differential scanning microcalorimetry (DSC). It was found that in starch from tubers of rolB plants the melting temperature of crystalline lamella was lower and their thickness was less than that in wild-type potato. In tubers of rolC plants starch differed from starch in wild-type plants by a higher melting temperature, reduced melting enthalpy, and a greater thickness of crystalline lamellae. The melting of starch from tubers of rolC plants proceeded as the melting of two independent crystalline structures with melting temperatures of 338.0°K and 342.8°K. Overall data show that starches of different structure can be obtained by using transgenic approach.

Light–matter interactions can be strongly modified by the surrounding ***,we report on the first experimental observation of molecular spontaneous emission inside a highly non-local metamaterial based on a plasmonic nanorod *** show that the emission process is dominated not only by the topology of its local effective medium dispersion,but also by the non-local response of the composite,so that metamaterials with different geometric parameters but the same local effective medium properties exhibit different Purcell factors.A record-high enhancement of a decay rate is observed,in agreement with the developed quantitative description of the Purcell effect in a non-local *** engineered material non-locality introduces an additional degree of freedom into quantum electrodynamics,enabling new applications in quantum information processing,photochemistry,imaging and sensing with macroscopic composites.

20世纪的俄语经典文学在当下俄国依然遭遇着十分意识形态化的解读,本文作者认为,无论是土壤派批评还是自由派批评,在对苏维埃经典做出评价时往往都带有政治意图,本文以当下俄国批评对普里什文、格林、阿·托尔斯泰、布尔加科夫和普拉东诺夫五位作家两种截然不同的接受为例,说明"20世纪上半期的俄国经典文学离我们越远,就变得越是意识形态化,越能引起纷争","20世纪上半期的俄国经典文学正在成为政治斗争中一枚可以兑换的硬币"。作者主张,对于经典作家及其作品的真正合理的解读方式还是返回文本,返回特定的历史语境。
