Аннотация: This paper analyses aerosol particle number size distributions, particulate absorption at 570 nm wavelength and carbon monoxide (CO) measured between September 2006 and January 2010 at heights of 50 and 300 m at the Zotino Tall Tower Facility (ZOTTO) in Siberia (60.8 degrees N; 89.35 degrees E). Average number, surface and volume concentrations are broadly comparable to former studies covering shorter observation periods. Fits of multiple lognormal distributions yielded three maxima in probability distribution of geometric mean diameters in the Aitken and accumulation size range and a possible secondary maximum in the nucleation size range below 25 nm. The seasonal cycle of particulate absorption shows maximum concentrations in high winter (December) and minimum concentrations in mid-summer (July). The 90th percentile, however, indicates a secondary maximum in July/August that is likely related to forest fires. The strongly combustion derived CO shows a single winter maximum and a late summer minimum, albeit with a considerably smaller seasonal swing than the particle data due to its longer atmospheric lifetime. Total volume and even more so total number show a more complex seasonal variation with maxima in winter, spring, and summer. A cluster analysis of back trajectories and vertical profiles of the pseudo-potential temperature yielded ten clusters with three levels of particle number concentration: Low concentrations in Arctic air masses (400-500 cm(-3)), mid-level concentrations for zonally advected air masses from westerly directions between 55 degrees and 65 degrees N (600-800 cm(-3)), and high concentrations for air masses advected from the belt of industrial and population centers in Siberia and Kazakhstan (1200 cm(-3)). The observational data is representative for large parts of the troposphere over Siberia and might be particularly useful for the validation of global aerosol transport models.

    Swelling of larch wood in organic liquids
[Text] / S. R. Loskutov, A. A. Aniskina // Holzforschung. - 2008. - Vol. 62, Is. 3. - P357-361, DOI 10.1515/HF2008.052. - Cited References: 15 . - 5. - ISSN 0018-3830

Аннотация: The swelling of larch wood in 1-butanol, dimethyl sulfoxide, N,N-dimethyl formamide, ethylene glycol, ethanol, methyl cellosolve, 1-propanol and toluene was investigated at room temperature. The volumetric, tangential and radial swelling completion was lagging behind the liquid absorption process. The kinetic indices of swelling of larch wood were determined based on the equation of Kolmogorov-Erofeev. The volumetric swelling was related to molecular mass, molar volume, dielectric permittivity and integral heat of wood wetting. The anisotropy of wood swelling was characterized by the ratio of equilibrium tangential swelling to radial swelling (alpha(t)/alpha(r)). It was demonstrated that alpha(t)/alpha(r) is related to the dipole component of Hansen's parameter and cannot exceed the value 3.

    Long-term measurements of aerosol and carbon monoxide at the ZOTTO tall tower to characterize polluted and pristine air in the Siberian taiga
/ X. Chi [et al.] // Atmospheric Chemistry and Physics. - 2013. - Vol. 13, Is. 24. - P12271-12298, DOI 10.5194/acp-13-12271-2013 . - ISSN 1680-7316

Аннотация: Siberia is one of few continental regions in the Northern Hemisphere where the atmosphere may sometimes approach pristine background conditions. We present the time series of aerosol and carbon monoxide (CO) measurements between September 2006 and December 2011 at the Zotino Tall Tower Observatory (ZOTTO) in Central Siberia (61° N; 89° E). We investigate the seasonal, weekly and diurnal variations of aerosol properties (including absorption and scattering coefficients and derived parameters, such as equivalent black carbon (BC e), Angstrom exponent, single scattering albedo, and backscattering ratio) and the CO mixing ratios. Criteria were established to distinguish polluted from near-pristine air masses, providing quantitative characteristics for each type. Depending on the season, 23-36% of the sampling time at ZOTTO was found to be representative of a clean atmosphere. The summer pristine data indicate that primary biogenic and secondary organic aerosol formation are quite strong particle sources in the Siberian taiga. The summer seasons 2007-2008 were dominated by an Aitken mode around 80 nm size, whereas the summer 2009 with prevailing easterly winds produced particles in the accumulation mode around 200 nm size. We found these differences to be mainly related to air temperature, through its effect on the production rates of biogenic volatile organic compounds (VOC) precursor gases. In winter, the particle size distribution peaked at 160 nm, and the footprint of clean background air was characteristic for aged particles from anthropogenic sources at great distances from ZOTTO and diluted biofuel burning emissions from domestic heating. The wintertime polluted air originates mainly from large cities south and southwest of the site; these particles have a dominant mode around 100 nm, and the ?BCe/?CO ratio of 7-11 ng m -3 ppb-1 suggests dominant contributions from coal and biofuel burning for heating. During summer, anthropogenic emissions are the dominant contributor to the pollution particles at ZOTTO, while only 12% of the polluted events are classified as biomass-burning-dominated, but then often associated with extremely high CO concentrations and aerosol absorption coefficients. Two biomass-burning case studies revealed different ΔBCe/?CO ratios from different fire types, with the agricultural fires in April?2008 yielding a very high ratio of 21 ng m -3 ppb-1. Overall, we find that anthropogenic sources dominate the aerosol population at ZOTTO most of the time, even during nominally clean episodes in winter, and that near-pristine conditions are encountered only in the growing season and then only episodically. © Author(s) 2013.

Аннотация: The significant growth in applications of silver nanoparticles across -various branches of industry as well as in consumer products has caused concerns that nanosilver may have a toxic effect on the environment and human health and may have implications for eco-terorism. This paper presents research on antimicrobial effects of silver nanoparticles. We studied the cytotoxicity of silver nanoparticles via an MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-tetrazolium-bromid) assay that measures cell activity through the mitochondrial cleavage of a molecule that exhibits a change of colour that can be measured spectrophotometrically. NIH-3T3 (Swiss mouse embryo), HEP-G2 (human hepatocellular carcinoma), A-549 (human lung carcinoma), PC-12 (rat adrenal pheochromocytoma), and Colo-320 (human colon adenocarcinoma) cells were chosen in order to study different possible absorption paths of nanoparticles into the organism and various areas of particle accumulation in the body. The obtained MTT test results have shown that silver nanoparticles with concentrations of ∼1-10 ppm entering the body from air or liquid suspensions can present a potential risk to human health. © Springer Science+Business Media B.V. 2011.

    Free competition of tree fractions for resources and allometric correlations
/ V. G. Sukhovolsky // Zhurnal Obshchei Biologii. - 1997. - Vol. 58, Is. 5. - С. 87-88 . - ISSN 0044-4596

Аннотация: Optimisation approach used to describe tree growth supposes the allocation of resources for different ecological and physiological functions: photosynthesis, absorption and transport of substances, wind protection, etc. The author suggests a theoretical model that describes the distribution of mass for tree fractions and compares the model and experimental measurements of biomass of different fractions. The distribution of biomass can be described with the Zipf-Pareto equation of free competition. The method to evaluate the root biomass using the data on above-ground biomass of tree is proposed. The relations of equations used to describe the free competition and allometric growth were studied. It was shown that allometric equations can be derived from the equation of free competition under some special conditions.

Аннотация: This work is devoted to the complex research on temperature phase transitions in a CsScF4 crystal. The crystal structure was solved and refined at different temperatures by using the Rietveld method. Structural phase transitions were investigated by using the following spectroscopic methods, some of them for the first time: Brillouin spectroscopy, Raman spectroscopy, IR absorption spectroscopy and NMR. The symmetry analysis of the Brillouin zone center of all phases is presented. The vibrational spectra of the crystal in three phases have been calculated. The structural phase transition mechanism was determined. The transitions at T-1 = 475 K and T-2 = 317.5 K are of displacement type. The Raman soft modes have been associated with rotations of the ScF6 octahedral group.

Аннотация: The ground and excited states of the pheromone molecules produced by xylophagous insects (the bark beetle Ips typographus L., the black fir sawyer beetle Monochamus urussovi Fisch., and the black pine sawyer M. galloprovincialis Oliv.) were modeled using a quantum chemical method utilizing DFT (density functional theory) with the B3LYP functional. The absorption wavelengths (energies) and dipole moments were calculated; the transitions of electrons from occupied to empty molecular orbitals were considered. The computed data were used to assess the stability of pheromone molecules exposed to environmental factors, such as solar radiation and humidity. © 2017, Pleiades Publishing, Inc.

    Estimation of the thermal and photochemical stabilities of pheromones

Аннотация: The correlation between the kinetic stability of molecules against temperature and variations in their geometric structure under optical excitation is investigated by the example of different organic pheromone molecules sensitive to temperature or ultraviolet radiation using the density functional theory. The kinetic stability is determined by the previously developed method based on the calculation of the probability of extension of any structural bond by a value exceeding the limit value Lмах corresponding to the breaking of the bond under temperature excitation. The kinetic stability calculation only requires the eigenfrequencies and vibrational mode vectors in the molecule ground state to be calculated, without determining the transition states. The weakest bonds in molecules determined by the kinetic stability method are compared with the bond length variations in molecules in the excited state upon absorption of light by a molecule. Good agreement between the results obtained is demonstrated and the difference between them is discussed. The universality of formulations within both approaches used to estimate the stability of different pheromone molecules containing strained cycles and conjugated, double, and single bonds allows these approaches to be applied for studying other molecules.

    FTIR spectroscopy of early and latewood of Larix gmelinii growing along the polar treeline: the correlation between absorption bands and climatic factors
/ E. A. Tyutkova, S. R. Loskutov, N. P. Shestakov // Wood Mater. Sci. Eng. - 2019, DOI 10.1080/17480272.2018.1562495 . - Article in press. - ISSN 1748-0272
Аннотация: This paper presents the results of FTIR spectroscopy of the 1988–1998 annual ring early and latewood of Larix gmelinii (Rupr.) Rupr.) found along the polar treeline (Taimyr Peninsula, 70°52?53? N, 102°58?26? E). We analyzed samples of early and latewood to identify absorption bands of groups of wood components, as well as the bands that characterized the interactions among the components. We studied bound water spectral characteristics for wood formed in different years. An analysis of the correlation between the values of spectral absorption bands and mean monthly air temperature and precipitation showed that May-August weather had the greatest influence on the synthesis of the main polymeric components of early and latewood. Air temperature had a considerable effect on polymer composition of cell walls forming in early and latewood, whereas precipitation influenced only earlywood. FTIR spectroscopy is a promising tool to develop information on the biochemical composition of the walls of early and late tracheids of annual rings and on weather and climate influences on cell wall synthesis. © 2018, © 2019 Informa UK Limited, trading as Taylor & Francis Group.

    Changes in lignin structure during earlywood and latewood formation in Scots pine stems
/ G. F. Antonova [et al.] // Wood Sci Technol. - 2019. - Vol. 53, Is. 4. - P927-952, DOI 10.1007/s00226-019-01108-w . - ISSN 0043-7719
Аннотация: Lignification of earlywood and latewood during annual ring formation in Scots pine stem in the season occurs with opposite dynamics. The subject of this study was to examine the structure of lignin deposited at successive stages of secondary cell wall maturation of these two wood types. Lignin specimens derived from developing cells by the thioglycolic acid were analyzed by the methods of alkaline oxidation, alkaline and acid hydrolysis and IR Fourier spectroscopy. The composition of lignin structural subunits was found to change at each stage of lignification in dependence of the forming wood type. The molar ratio of p-hydroxyphenyl, guaiacyl and syringyl subunits in polymer was modified in earlywood and latewood oppositely. In the course of earlywood cell maturation, syringyl subunits in lignin increased in parallel with p-hydroxyphenyl units. During latewood lignification, syringyl and p-hydroxyphenyl subunits in lignin structure decreased, whereas guaiacyl subunits increased as secondary cell wall maturation. In lignin isolated from both wood types, the ether-bound carbohydrates were more than by an order of magnitude of ester-bound carbohydrates. In early xylem, the content of ether-bound carbohydrates practically did not change during lignin deposition, whereas carbohydrates with ester linkages gradually decreased toward mature xylem. Lignification in latewood was accompanied by the decline of both ester-linked and ether-linked carbohydrates with a sharp increase in the latter in mature xylem. Hemicelluloses, included in such bonds, contained mainly the residues of xylose and arabinose. The composition and the content of hydroxycinnamic acids, taking part in these linkages, also changed in dependence of lignification steps and wood type. The data received are in agreement with the alterations in absorption IR spectra of lignins isolated from the cells at the beginning of lignification and mature xylem. The reasons for the differences in the lignin structure during earlywood and latewood development are discussed. © 2019, Springer-Verlag GmbH Germany, part of Springer Nature.

Аннотация: Vast carbon reservoirs hosted in the Arctic realm may trigger a significant positive feedback loop in the global Earth climate system under existing global warming scenarios. Nevertheless, sparse coverage of the Arctic region with greenhouse gas (GHG) observation network limits our understanding of carbon cycling in this environment and making predictions about a fate of carbon conserved in currently frozen ground. Especially critical gaps exist in the vast Arctic territories of Siberia, where solely 3 continuous atmospheric carbon observation stations are currently operational and located entirely in Northeastern Siberia: Atmospheric carbon observation station Ambarchik (69.62° N, 162.30° E), the Tiksi hydrometeorological observatory (71.6°N, 128.9° E) and the Cape Baranova ice base observatory on the Bolshevik Island, Severnaya Zemlya (79.3° N, 101.8° E). In this paper we introduce a newly established coastal atmospheric carbon observation station Dikson (73.33° N, 80.34° E), jointly maintained by the V. N. Sukachev Institute of Forest SB RAS (Krasnoyarsk, Russia), Joint Directorate of Taimyr Nature Reserves (Norilsk, Russia) and the Max Planck Institute for Biogeochemistry (Jena, Germany), which is intended to fill the gap in the atmospheric GHG observations in the northcentral Siberian domain. The general west wind drift expected at the location of the site makes it more sensitive to the northern latitudes of Western Siberia, as compared to the other, more eastern, stations, which, due to the specific cyclonic activity that prevents air from the Icelandic low pressure minimum spreading towards the east of Severnaya Zemlya. The measurement site, which was launched in September 2018, is located on the Taimyr Peninsula near the gulf of the Yenisei River at the coast of the Kara Sea. Atmospheric mole fractions of CO2, CH4 and H2O at the station are continuously measured by an analyzer based on the cavity ring-down spectroscopy (CRDS) technique (G2301-f, Picarro Inc., USA). Data quality control of trace gas measurements is achieved by regular calibrations against WMO-traceable reference gases, an applied water vapor correction and meteorological records that permit data screening. A preliminary wind analysis and calculated backward trajectories from hot spots downwind of the measurement site reveal that during late spring and summer tundra landscapes of the upper part of the Taimyr Peninsula, the gulf of the Yenisei River and the adjacent shelf areas of the Arctic Ocean are the major contributors to the observed variability at the station. Conversely in winter (frost period) this site becomes receptive to air masses originated in the continental domain and containing the anthropogenic GHGs, e.g. the gas production on the Tazovskiy Peninsula. Here we summarize the scientific rationale of the new site, give technical details of the instrumental setup, analyze the local environments and present some exemplary results. © SGEM2019.

forest-forming coniferous species -- mixed forests -- drought resistance -- Siberia

Аннотация: The limits of individual variation of trees by the water-retaining capacity of needles in populations of forest-forming coniferous species (Scots pine, Siberian pine, Siberian spruce and Siberian fir) growing in the conditions of the mountainous, middle and northern taiga of Central and Eastern Siberia were studied. It is found that among the compared evergreen species, Scots pine and Siberian pine are characterized by the highest intrapopulation variation in the rate of needles dehydration; Siberian spruce and Siberian fir are characterized by greater variability in the ability of needles to water absorption. However, in samples of the last two species, the share of trees with a low rate of water loss is quite large, even in wet habitats. In more drought-resistant pine species there is a smaller part of trees, which quickly evaporate moisture and have a high water capacity of needles. While a smaller part of trees of Siberian spruce and Siberian fir are less resistant to dehydration and differ by low water capacity of needles. While in Siberian spruce and Siberian fir a smaller part are trees less resistant to dehydration with low water capacity of needles. We revealed the significant differences between species in mixed stands and between geographic populations of species by water-retaining capacity of needles. The highest values of this indicator were obtained for Scots pine and Siberian spruce from Yakutia, as well as for old-growth trees of Siberian pine from the Western Sayan. The necessity of preserving old-growth stands and trees, characterized by the greatest drought resistance of needles, especially hygrophilous dark coniferous species in a changing climate is emphasized.The obtained data and correlations between the used features allow us to estimate one of the components of drought resistance of taiga populations of coniferous species and their intrapopulation diversity.

Аннотация: This paper presents the results of FTIR spectroscopy of the 1988-1998 annual ring early and latewood of Larix gmelinii (Rupr.) Rupr.) found along the polar treeline (Taimyr Peninsula, 70 degrees 52' 53 '' N, 102 degrees 58'26 '' E). We analyzed samples of early and latewood to identify absorption bands of groups of wood components, as well as the bands that characterized the interactions among the components. We studied bound water spectral characteristics for wood formed in different years. An analysis of the correlation between the values of spectral absorption bands and mean monthly air temperature and precipitation showed that May-August weather had the greatest influence on the synthesis of the main polymeric components of early and latewood. Air temperature had a considerable effect on polymer composition of cell walls forming in early and latewood, whereas precipitation influenced only earlywood. FTIR spectroscopy is a promising tool to develop information on the biochemical composition of the walls of early and late tracheids of annual rings and on weather and climate influences on cell wall synthesis.

    Ранняя инструментальная диагностика грибных инфекций в древесине
[Текст] / С. Р. Лоскутов, Е. А. Тютькова, М. А. Пляшечник, Е. А. Петрунина [и др.] // Сибирский лесной журнал. - 2021. - № 6. - С. 39-45, DOI 10.15372/SJFS20210604 . - ISSN 2311-1410

Аннотация: Исследовалось изменение физико-химических показателей древесины сосны обыкновенной ( Pinus sylvestris L.) на ранней стадии развития в ней грибной инфекции с помощью методов ИК-Фурье спектроскопии и сканирующей электронной микроскопии (СЭМ). Анализ СЭМ-изображений локально поврежденной древесины показал наличие гифов как в межклеточном пространстве, так и люменах единичных трахеид. Из сравнения результатов анализов поврежденной и здоровой древесины установлен ряд параметров ИК-спектров - изменение отношений интенсивности поглощения на характеристических частотах (волновых числах, см-1) для полимеров древесинного вещества (гемицеллюлоз, целлюлозы, лигнина) и грибов (хитина и глюканов) I 1512/898, I 1512/1157, I 1512/894, I 1647/1551, I 1695/1533, I 1620/1564, позволяющий идентифицировать наличие и степень воздействия грибной инфекции на древесину. Представлен новый вариант оценки изменений в строении древесинного вещества, заключающийся в сравнительном анализе вторых производных ИК-спектров поглощения здоровой и поврежденной древесины. Способ существенно улучшает визуализацию изменений по спектрам и позволяет с большей точностью определять «адреса» воздействия грибной инфекции на древесинное вещество по интенсивности и частоте полос поглощения. Кроме того, может быть использован для мониторинга появления азотсодержащих соединений в результате присутствия грибов. Реализованные методические приемы указывают на возможность использования в работе радиальных кернов с целью проведения их сопряженного анализа, «привязывая» результаты ИК-Фурье спектроскопии к параметрам годичных колец и в целом к хронологиям, а также соотнося их с морфолого-анатомическим строением годичного кольца и отдельных трахеид по данным сканирующей электронной микроскопии. Предложенный подход к диагностике повреждения древесины на ранней стадии развития грибной инфекции признан эффективным, экспрессным и не требующим сложной пробоподготовки
The changes in the physico-chemical parameters of Scotch pine Pinus sylvestris L. wood were studied at an early stage of a fungal infection development in it using the methods of IR-Fourier spectroscopy and scanning electron microscopy (SEM). Analysis of SEM-images of locally damaged wood showed the presence of hyphae both in the intercellular space and in the lumens of single tracheids. From the comparison of the results of analyses of damaged and healthy wood, a number of parameters of the IR spectra were established - a change in the ratio of the absorption intensity at characteristic frequencies (wave numbers, cm-1) for polymers of wood substance (hemicellulose, cellulose, lignin) and fungi (chitin and glucans) I 1512/898, I 1512/1157, I 1512/894, I 1647/1551, I 1695/1533, I 1620/1564, which allows identifying the presence and degree of exposure to fungal infection on wood. A new version of the assessment of changes in the structure of the wood substance is presented, which consists in a comparative analysis of the second derivatives of the IR absorption spectra of sound and damaged wood. The method significantly improves not only the visualization of changes in the spectra, but also allows to more accurately determine the «addresses» of the impact of a fungal infection on the wood substance by the intensity and frequency of the absorption bands. In addition, it can be used to monitor the appearance of nitrogen-containing compounds because of the presence of fungi. The implemented methodological techniques indicate the possibility of using radial cores in the work for the purpose of conducting their conjugate analysis, «linking» the results of IR-Fourier spectroscopy to the parameters of the annual rings and, in general, to chronologies, as well as correlating them with the morphological and anatomical structure of the annual ring and individual tracheids according to scanning electron microscopy data. The proposed approach to the diagnosis of wood damage at an early stage of the development of a fungal infection is effective, rapid and does not require complex sample preparation
