    Trophic effects of sponge feeding within Lake Baikal\u27s littoral zone .2. Sponge abundance, diet, feeding efficiency, and carbon flux

    Endemic freshwater demosponges in the littoral zone of Lake Baikal, Russia, dominate the benthic biomass, covering 44% of the benthos. We measured in situ sponge abundance and,orating and calculated sponge-mediated Fluxes of picoplankton (plankton \u3c2 mu m) for two common species, Baikalospongia intermedia and Baikalospongia bacillifera. By means of dual-beam how cytometry, we found retention efficiencies ranging from 58 to 99% for four types of picoplankton: heterotrophic bacteria, Synechococcus-type cyanobacteria, autotrophic picoplankton with one chloroplast, and autotrophic picoplankton with two chloroplasts. By using a general model for organism-mediated fluxes, we conservatively estimate that through active suspension feeding, sponges are a sink for 1.97 g C d(-1) m(-1), mostly from procaryotic cell types. Furthermore, grazing by these extensive sponge communities can create a layer of picoplankton-depleted water overlying the benthic community in this unique lake

    Two approaches for synthesis of a great variety of 3-N-substituted 1H-thieno[3,2-d]pyrimidine-2,4-diones have been investigated. The first one is based on the interaction of methyl 3-aminothiophene-2-carboxylate with isocyanates, which is a good way for preparation of 3-N-aryl-1H-thieno[3,2-d]pyrimidine-2,4-diones. The key step of the other one, which allows introduction of different alkyl substituents in position 3, is oxidation of 4-oxo-2-thioxo-2,3- dihydrothieno[3,2-d]pyrimidines prepared by interaction of 3-isothiocyanatothiophene-2-carboxylate and the primary aliphatic amines with hydrogen peroxide. Alkylation of the intermediates obtained in both ways resulted in 1-N-alkyl-3-N-substituted 1Н-thieno[3,2-d]pyrimidine-2,4-diones. 1H NMR spectra of the target molecules contain the signals of thiophene cycle protons H-6 (Ξ΄ 8.02-8.18 ppm) and H-7 (Ξ΄ 7.06-7.15 ppm) together with the signal of CH2 groups in position 1 of the heterocyclic system in the range of Ξ΄ 4.70-5.20 ppm. The antimicrobial activity of the compounds synthesized has been investigated by the agar well diffusion method. It has been determined that the compound with phenyl substituents in position 3 and o-methylbenzyl substituent in position 1 is the most active antimicrobial agent. The 1-N-alkyl derivatives of 2,4-dioxo-1,4-dihydro-2H-thieno[3,2-d]pyrimidine-3-yl)propanoic acid benzyl amide appeared to be active against the strains of Staphylococcus aureus and Bacillus subtilis.Π‘Ρ‹Π»ΠΎ исслСдовано Π΄Π²Π° ΠΏΠΎΠ΄Ρ…ΠΎΠ΄Π° ΠΊ синтСзу ΠΏΡ€ΠΎΠΈΠ·Π²ΠΎΠ΄Π½Ρ‹Ρ… 3-N-Π·Π°ΠΌΠ΅Ρ‰Π΅Π½Π½Ρ‹Ρ… 1H-Ρ‚ΠΈΠ΅Π½ΠΎ[3,2-d]ΠΏΠΈΡ€ΠΈΠΌΠΈΠ΄ΠΈΠ½-2,4-Π΄ΠΈΠΎΠ½ΠΎΠ², ΠΊΠΎΡ‚ΠΎΡ€Ρ‹Π΅ способны ΠΎΠ±Π΅ΡΠΏΠ΅Ρ‡ΠΈΡ‚ΡŒ большоС химичСскоС Ρ€Π°Π·Π½ΠΎΠΎΠ±Ρ€Π°Π·ΠΈΠ΅.

    By alkylation of the products of diethyl 3-methyl-5 {[(methylthio)carbonothioyl]amino}-2,4-thiophenedicarboxylate interactionwith benzylamines the novel derivatives of ethyl 5-methyl-2-(alkylthio)-4-oxo-3,4-dihydrothieno[2,3-d]pyrimidine-6-carboxylates have been obtained. It has been found that the signal of the CH2-group adjacent to the nitrogen atom in position 3 of thieno[2,3-d]pyrimidine system is always observed in the range of 5.35-5.40 ppm, while the position of the signal of methythylene-group connected with the sulfur atom much depends upon the structure of the radical attached to this group. IR-spectra of all the compounds contain the intensive Π‘=О stretching band at 1721-1678 cm-1; the spectra of the compounds with amide function contain bands of stretching N–H of 3280-3263 cm-1, while nitriles have the band of stretching C≑N vibrations near 2250 сm-1. It has been determined that all of the compounds are mostly active against the strain of Candida aibicans fungi. The most resistant microorganism was found to be the strains of Staphylococcus aureus. The only exception is the derivative modified with the thioacetic acid residue in position 2 and unsubstituted benzyl in position 3, which appeared to be highly active against Staphylococcus aureus strain. Amides of thioactetic acid modified in position 3 with 3,4-dichlorobenzyl substituent and thioacetamide substituents in position 2 are active against Pseudomonas aeruginosa, as well as the compound, which contains 3-chlorobenzyl substituent in position 3 and p-chlorobenzotiol substituents in position 2 of thieno[2,3-d]pyrimidine.ΠŸΡƒΡ‚Π΅ΠΌ алкилирования ΠΏΡ€ΠΎΠ΄ΡƒΠΊΡ‚ΠΎΠ² взаимодСйствия диэтил 3-ΠΌΠ΅Ρ‚ΠΈΠ»-5-{[(ΠΌΠ΅Ρ‚ΠΈΠ»Ρ‚ΠΈΠΎ)ΠΊΠ°Ρ€Π±ΠΎΠ½ΠΎΡ‚ΠΈΠΎΠΈΠ»]Π°ΠΌΠΈΠ½ΠΎ}-2,4-тиофСндикарбоксилата с Π±Π΅Π½Π·ΠΈΠ»Π°ΠΌΠΈΠ½Π°ΠΌΠΈ ΠΏΠΎΠ»ΡƒΡ‡Π΅Π½Ρ‹ Π½ΠΎΠ²Ρ‹Π΅ ΠΏΡ€ΠΎΠΈΠ·Π²ΠΎΠ΄Π½Ρ‹Π΅ этил 5-ΠΌΠ΅Ρ‚ΠΈΠ»-2-(Π°Π»ΠΊΠΈΠ»Ρ‚ΠΈΠΎ)-4-оксо-3,4-Π΄ΠΈΠ³ΠΈΠ΄Ρ€ΠΎΡ‚ΠΈΠ΅Π½ΠΎ[2,3-d]ΠΏΠΈΡ€ΠΈΠΌΠΈΠ΄ΠΈΠ½-6-карбоксилатов.

    Guardianship for Popular Sobriety in Russia at the Beginning of 20th Century: from Wine Monopoly to β€œDry Law”

    Get PDF
    TheΒ article is devoted to theΒ guardianship ofΒ popular sobrietyΒ β€” institutions created by theΒ government ofΒ theΒ Russian Empire at theΒ end ofΒ theΒ 19th century to organize theΒ fight against excessive alcohol consumption at theΒ provincial and district levels. TheΒ study describes theΒ situation with theΒ consumption ofΒ alcoholic beverages in Russia at theΒ turn ofΒ theΒ XIXβ€”XXΒ centuries, provides theΒ main provisions ofΒ theΒ state wine monopoly, introduced in 1895 with theΒ direct participation ofΒ theΒ Minister ofΒ Finance S.Β Yu.Β Witte. Based on theΒ Charter ofΒ Guardianship of People’s Sobriety, theΒ authors describe their powers, composition, and features ofΒ work organization. Based on theΒ analysis ofΒ diverse sources (including unpublished archival sources), theΒ article characterizes theΒ diverse activities ofΒ guardianship in Russia at theΒ beginning ofΒ theΒ 20th century, as well as its assessment by contemporaries. TheΒ conclusion is made about theΒ relatively low efficiency ofΒ theΒ work ofΒ sober institutions due to their bureaucracy and insufficient funding. TheΒ article describes theΒ problem ofΒ reforming theΒ guardianship, which was discussed with varying intensity in theΒ 1900β€”1910s in theΒ Ministry ofΒ Finance, theΒ State Council, public and zemstvo circles. Special attention is paid to theΒ analysis ofΒ theΒ problems faced by theΒ guardianship ofΒ popular sobriety during theΒ First World War after theΒ introduction ofΒ theΒ β€œProhibition”. TheΒ scientific novelty ofΒ theΒ research lies in anΒ attempt to analyze theΒ entire set ofΒ issues related to theΒ activities ofΒ guardianship in theΒ period under review, starting from documents of aΒ legal and office-work nature, statistical materials, periodicals, journalistic and memoir literature

    Hydrodynamical Simulation of Astrophysical Flows: High-Performance GPU Implementation

    Full text link
    We present a new hydrodynamical code GPUPEGAS 2.0 for 3D simulation of astrophysical flows using the GPUs. This code is an extension of GPUPEGAS code developed in 2014 for simulation of interacting galaxies. GPUPEGAS 2.0 is based on the Authors' numerical method of high order of accuracy for smooth solutions with small dissipation of the solution in discontinuities. The high order of accuracy and small dissipation are achieved by using the piecewise-linear representation of the physical variables in each dimension. The Rusanov flux allows one to simply vectorize the solution of the Riemann problem. The code was implemented for the cluster supercomputers NKS-30T (Siberian Supercomputer Center, SB RAS) and Uran (Institute of Mathematics and Mechanics, UrB RAS) using the hybrid MPI+CUDA technology. To avoid the compute capability-specific implementations of reduction routines, the Thrust library was used. The optimal parameters for kernel function were found for the three-dimensional computation grid. The Sedov point blast problem was used as a main test one. The numerical experiment was performed to simulate the hydrodynamics of the type II supernova explosion for the grid size of 2563. A set of experiments was performed to study performance and scalability of the developed code. The performance of 25 GFLOPS was achieved using a single Tesla M2090 GPU. The speedup of 3 times was achieved using a node with 4 GPUs. By using 16 GPUs, 70% scalability was achieved. Β© 2019 IOP Publishing Ltd.
