Аннотация: We study the effect of physical, chemical and biological processes on gas exchange of CO2 in the air-water system in Lake Baikal. Photosynthesis of aquatic biota is known to play a crucial role in changing the concentration of carbon dioxide in the water. Fluorescent methods are considered to be of high performance in problems of determining quantitative characteristics of biomass, however they require preliminary calibration directly for a specific type of plankton. In the pelagic zone of Lake Baikal the species composition, quantitative and spatial distribution of phytoplankton are characterized by strong spatial and temporal variability. Therefore, the fluorescent devices calibration on a single reference does not provide acceptable accuracy of quantitative assessment of the biomass. The results discussed in the paper were obtained by shipboard measurements during the Baikal campaign of 2010-2011. Correlation between the biomass in 25-meter water layer and the integral value of the fluorescent signal in this layer was obtained for calibration. The report discusses the advantages and disadvantages of the chosen methods and the results of retrieval of the vertical profiles of the biomass for stations in the pelagic zone of Lake Baikal in spring for the 2010-2011 biennium.

Аннотация: The paper discusses the changes hydro-optical parameters that characterize the qualitative composition of dissolved organic matter (DOM), during fractional filtering though large (4.5 mu m and 1.76 mu m) and small (0.9 mu m) filters. A loess reservoir lake Khanka containing great amount of suspended inorganic matter were selected as the research object. In order to assess changes in the composition of the DOM the following parameters were selected: index of the degree exponent of absorption spectrum, the specific absorption coefficient, relative specific fluorescence yield and relative specific fluorescence,. The research has shown that not only the content of organic matter during adsorption on the surface of the suspension is changing during filtration, but also the composition.

Аннотация: Using fluorimeter Junior PAM (Heinz Walz GmbH, Germany) the fluorescence parameters of leaves of Betula pendula are investigated. A linear dependence of the maximum fluorescence (Fm) of leaves from the ratio of total chlorophylls concentration to concentration of carotenoids is obtained. Such dependence is found for samples collected during the period of vegetation and for simultaneous selection of colored leaves.

Аннотация: Sunflower plants were grown in the laboratory under continuous light on the ground, the sand and the liquid medium. Fluorescence parameters were measured using PAM fluorimeter (Walz, Germany) and optical spectrophotometric sensor CCM-200 plus, Opti-Sciences, USA). The change of parameters of Fo, Fm, Fv/Fm, ETR and CCI in leaves after addition of oil at a concentration of 6 g/kg is investigated. It is shown that the parameters CCI and ETR (electron transport rates) are most sensitive to oil pollution. The value of the CCI in sunflower leaves increased (compared to control) after the addition of oil in the soil and decreased after the addition of oil in sand and liquid culture medium. © 2016 SPIE.

Аннотация: From presents own experimental data and literature analysis it follows that in cases where the maximum fluorescence intensity (Fm) of plant leaves was determined using the PAM fluorimeter (Walz, Germany), the dependence of Fm on the relation of total chlorophyll concentration to carotenoid concentration (which was determined according to Wintermans I. F., De Mots A, 1965; D. Wettstein, 1957) is characterized by a linear equation. © 2016 SPIE.

Аннотация: The authors propose a novel type of ion-selective membranes, which combine the advantages of ceramic nanofibrous media with good electrical conductivity. The membranes are produced from Nafen alumina nanofibers (diameter around 10nm) by filtration of nanofiber suspension through a porous support followed by drying and sintering. Electrical conductivity is achieved by depositing a thin carbon layer on the nanofibers by chemical vapor deposition (CVD). Raman and FTIR spectroscopy, X-ray fluorescence analysis, and TEM are used to confirm the carbon structure formation. The deposition of carbon leads to decreasing porosity (from 75 to 62%) and specific surface area (from 146 to 107m(2) g(-1)) of membranes, while the pore size distribution maximum shifts from 28 to 16nm. Measurements of membrane potential in an electrochemical cell show that the carbon coated membranes acquire high ionic selectivity (transference numbers 0.94 for anion and 0.06 for cation in aqueous KCl). Fitting the membrane potential data by the Teorell-Meyer-Sievers model shows that the fixed membrane charge increases proportionally with increasing electrolyte concentration. The carbon coated membranes are ideally polarizable for applied voltages from -0.5 to +0.8V. The potential applications of produced membranes include nano- and ultrafiltration, separation of charged species, and switchable ion-transport selectivity.

Аннотация: The process of gas exchange of CO2 in the atmosphere–water system and its relation to the daily course of variable fluorescence of phytoplankton is studied on the basis of long-term (2004–2014) measurements during the open water period for Lake Baikal. It is found that the decrease in photosynthetic activity of plankton is almost synchronous to the increase in the CO2 flux from atmosphere to water. It follows from comparison of the spring and summer data with December measurements that the daily decrease in variable fluorescence of phytoplankton is caused by the internal daily rhythm of the photosynthetic activity of plankton. © 2018, Pleiades Publishing, Ltd.
