Сравнительная характеристика торфов Томской области и республики Алтай

В данной работе была проведена сравнительная характеристика торфов Томской области и республики Алтай. Для этих торфов были определены технический и групповой составы. В результате исследований выявлено, что торфа с месторождений Томской области и республики Алтай отличаются по степени разложения и зольности. В торфах республики Алтай получили большее содержание гуминовых кислот и лигнина по сравнению с торфами Томской области . Кроме этого, в торфах республики Алтай выявлено низкое содержание битумов и углеводного комплекса и повышенное содержание гуминовых кислот и лигнина. Установлено, что на базе месторождений республики Алтай возможна организация производства гуминовых кислот и битумов в ограниченных размерах.In this work the comparative characteristic of peats of the Tomsk region and Altai Republic has been carried out. For these peats, the technical and group compositions were determined. As a result of the researches it is revealed that peats from deposits of the Tomsk region and Altai Republic differ on extent of decomposition and an ash-content. In peats of Altai Republic have received the bigger content of humic acids and a lignin in comparison with peats of the Tomsk region. Besides, in peats of Altai Republic the low content of bitumens and a carbohydrate complex and the increased content of humic acids and a lignin is revealed. It is established that on the basis of fields of Altai Republic the organization of production of humic acids and bitumens in limited sizes is possible

Analysis of 2D airglow imager data with respect to dynamics using machine learning

We demonstrate how machine learning can be easily applied to support the analysis of large quantities of excited hydroxyl (OH*) airglow imager data. We use a TCN (temporal convolutional network) classification algorithm to automatically pre-sort images into the three categories “dynamic” (images where small-scale motions like turbulence are likely to be found), “calm” (clear-sky images with weak airglow variations) and “cloudy” (cloudy images where no airglow analyses can be performed). The proposed approach is demonstrated using image data of FAIM 3 (Fast Airglow IMager), acquired at Oberpfaffenhofen, Germany, between 11 June 2019 and 25 February 2020, achieving a mean average precision of 0.82 in image classification. The attached video sequence demonstrates the classification abilities of the learned TCN. Within the dynamic category, we find a subset of 13 episodes of image series showing turbulence. As FAIM 3 exhibits a high spatial (23 m per pixel) and temporal (2.8 s per image) resolution, turbulence parameters can be derived to estimate the energy diffusion rate. Similarly to the results the authors found for another FAIM station (Sedlak et al., 2021), the values of the energy dissipation rate range from 0.03 to 3.18 W kg−1

Schallemissionsanalyse zur Untersuchung des Schädigungsverhaltens im Auszugversuch eines in Beton eingebetteten Multifilamentgarns

Zur Untersuchung der Schädigungs- und Versagensmechanismen eines in Beton eingebetteten Multifilamentgarns im Auszugversuch wurde die Schallemissionsanalyse zur Identifizierung und Lokalisierung von Filamentbrüchen eingesetzt. Im ersten Schritt wurden dazu die Schall emittierenden Ursachen (Filamentriss, Filamentablösung und Mikroriss im Beton) für eine Differenzierung charakterisiert. Es wurden Versuche zur Erzeugung von isolierten Signalen durchgeführt, welche mit Hilfe der Signal- und Frequenzanalyse untersucht wurden. Bei dem durchgeführten Garnauszugversuch konnte eine hohe Lokalisierungsgenauigkeit der Filamentbrüche erzielt werden. Der Schädigungsverlauf des Garns während des Auszugversuchs konnte detailliert untersucht werden

Deformation around neutron-rich Cr isotopes in axially symmetric Skyrme-Hatree-Fock-Bogoliubov method

We analyse deformation mechanism in neutron-rich Cr, Fe and Ti isotopes with N=32-44 by means of a Skyrme-Hartree-Fock-Bogoliubov mean-field code employing a two-dimensional mesh representation in the cylindrical coordinate system. Evaluating systematically the quadrupole deformation energy, we show that the Skyrme parameter set SkM* gives a quadrupole instability around the neutron number N$\sim$38-42 in Cr isotopes, where the deformation energy curve suggests a transitional behavior with a shallow minimum extending to a large prolate deformation. Roles of a deformed N=38 gap and the position of the neutron g9/2 orbit are analysed in detail

Discovery of the Cadmium Isotopes

Thirty-seven cadmium isotopes have so far been observed; the discovery of these isotopes is discussed. For each isotope a brief summary of the first refereed publication, including the production and identification method, is presented.Comment: to be published in Atomic Data and Nuclear Data Table

Spuren der durch die Eruption des Hunga Tonga-Hunga Ha'apai ausgelösten Druckwelle auch in der Mittleren Atmosphäre über Europa

On January 15th 2022 the Hunga Tonga – Hunga Ha'apai volcano erupted and generated strong atmospheric pressure waves of which some propagated several times across the globe. At the Environmental Research Station “Schneefernerhaus” (UFS), as well as in whole Europe, signals could be detected even at MLT (Mesosphere-Lower-Thermosphere) heights (80-100 km) using the GRIPS (GRound-based Infrared P-branch Spectrometer) and the BAIER (Bavarian Airglow ImagER) instruments for the observation of the OH and the O2 airglow
