An effective palynological preparation procedure using hydrogen peroxide [PDF]
Most pre-Quaternary palynology samples are currently prepared by demineralization of the sediment/sedimentary rock matrix using hydrochloric and hydrofluoric acids (HCl and HF respectively).

The Far-Infrared Spectral Energy Distributions of X-ray-selected Active Galaxies [PDF]
[Abridged] We present ISO far-infrared (IR) observations of 21 hard X-ray selected AGN from the HEAO-1 A2 sample. We compare the far-IR to X-ray spectral energy distributions (SEDs) of this sample with various radio and optically selected AGN samples ...

The study of the trait “plant height” in winter bread wheat in the south of the Rostov region
The problem of resistance to lodging during winter wheat cultivation is of great relevance in modern conditions. This trait largely correlates to plant height.

Subdiffractional focusing and guiding of polaritonic rays in a natural hyperbolic material [PDF]
Uniaxial materials whose axial and tangential permittivities have opposite signs are referred to as indefinite or hyperbolic media. In such materials, light propagation is unusual leading to novel and often non-intuitive optical phenomena. Here we report

Double-beam optical method and apparatus for measuring thermal diffusivity and other molecular dynamic processes in utilizing the transient thermal lens effect [PDF]
A sample material was irradiated by relatively high power, short pulses from a dye laser. Energy from the pulses was absorbed by the sample material, thereby forming a thermal lens in the area of absorption.
