MODERN EDUCATIONAL TECHNOLOGIES AS A CONDITION FOR THE SUCCESSFUL IMPLEMENTATION OF THE INDIVIDUAL EDUCATIONAL PROGRAM OF STUDENTS

In the modern model of education the attention of teachers is paid to the implementation of the individual educational route of the student. The article discusses the possibilities of modern educational technologies. The problem field of research is a contradiction between the need for higher education to implement the individual educational route of the student and the lack of attention of teachers to the selection of appropriate educational technologies. The aim of the study was to study the possibilities of modern educational technologies to strengthen the individuality, subjectivity, human capital of the student

USING THE BIOGRAPHICAL METHOD IN STUDENTS TRAINING FOR SOCIAL WORK

The article describes the possibility of using the biographical method at students’ preparation to the decision of people’s social problems who turned out to be in a difficult vital situation. A research novelty consists of using the philosophical-anthropological approach as a methodological basis, that is oriented to understanding of client as a Person, whose vital problems are related to such unsteady forms of life as a risk, fear, trust, meeting, failure, crisis, life, history of life, fate, event, case. A research aim is a study of students’ readiness to the practical using of the biographical method in the activities of a social worker. Basic methods for realization of this aim are working with basic concepts relevant to the using of the biographical method: pedagogical workshop, portrait of “Me”, collage, reflection essay. The main results of the study were new topics of students’ research works, made by using the biographical method. In practical part of researches students use the quality analysis of the personal (correspondence, photos, autobiographies) and official (descriptions, archived data) documents, survey methods (telling clients about their life, relatives’ evidence about the stages of the client's life).

30-year cone production dynamics in Siberian stone pine (Pinus sibirica) in the southern boreal zone: a causal interpretation

Siberian stone pine is a keystone species for Siberia, and numerous studies have analyzed Siberian stone pine seeding dynamics in connection with the dynamics of weather conditions. However, all studies were based on observations before 1990. The aim of the study was to expand our knowledge about the balance of weather and climatic factors in the regulation of cone production to enable conclusions about the current reproductive function in Siberian stone pine. We monitored Siberian stone pine cone production in the southeastern region of the Western Siberian Plain, in association with climatic factors, over a period of 30 years. To analyze the relationship with weather conditions, we used the trait mature cone number per tree and weather data obtained from the weather station in Tomsk. During this period, cone production decreased by about one-third, mainly caused by the complete absence of high yields. The main factor negatively affecting cone production was late spring frost: severe frost occurring with a large accumulated sum of effective temperatures resulted in full cone loss, and light frost substantially reduced cone number. A less important but significant climatic factor was September temperature: as the temperature increased, the cone number decreased in the following year. Over the last 30 years, the sum of the effective temperatures at which the last spring frost occurs, as well as the average September temperature, increased considerably, resulting in reduced cone production. If the current climatic trend is maintained, and especially if it is strengthened, Siberian stone pine cone production in the southern boreal forest zone on the Western Siberian Plane is unlikely to provide for the effective renewal of the species

TNT biotransformation and detoxification by a \u3ci\u3ePseudomonas aeruginosa\u3c/i\u3e strain

Successful microbial-mediated remediation requires transformation pathways that maximize metabolism and minimize the accumulation of toxic products. Pseudomonas aeruginosa strain MX, isolated from munitionscontaminated soil, degraded 100 mg TNT L-1 in culture medium within 10 h under aerobic conditions. The major TNT products were 2-amino-4,6-dinitrotoluene (2ADNT, primarily in the supernatant) and 2,2′- azoxytoluene (2,2′AZT, primarily in the cell fraction), which accumulated as major products via the intermediate 2-hydroxylamino-4,6-dinitrotoluene(2HADNT). The 2HADNT and 2,2′AZT were relatively less toxic to the strain than TNT and 2ADNT. Aminodinitrotoluene (ADNT) production increased when yeast extract was added to the medium. While TNT transformation rate was not affected by pH, more HADNTs accumulated at pH 5.0 than at pH 8.0 and AZTs did not accumulate at the lower pH. The appearance of 2,6-diamino-4-nitrotoluene (2,6DANT) and 2,4-diamino-6-nitrotoluene (2,4DANT); dinitrotoluene (DNT) and nitrotoluene (NT); and 3,5-dinitroaniline (3,5DNA) indicated various routes of TNT metabolism and detoxification by P. aeruginosa strain MX

Solubility of Benzo[a]pyrene and Organic Matter of Soil in Subcritical Water

A dynamic subcritical water extraction method of benzo[a]pyrene from soils is under consideration. The optimum conditions for benzo[a]pyrene extraction from soil are described including the soil treatment by subcritical water at 250 °C and 100 atm for 30 min. The effectiveness of developed method was determined using the matrix spiking recovery technique. A comparative analysis was made to evaluate the results of benzo[a]pyrene extraction from soils using the subcritical water and organic solvents. The advantages of the subcritical water extraction involve the use of ecologically friendly solvent, a shorter time for the analysis and a higher amount of benzo[a]pyrene extracted from soil (96 %). The influence of subcritical water extraction on soil properties was measured the investigation of the processes occurring within soil under the influence the high temperature and pressure. Under appropriate conditions of the experiment there is the destruction of the soil organic matter while the composition of the soil mineral fraction remains practically unchanged

Adsorptive bioremediation of soil highly contaminated with crude oil

12 páginas.- 6 figuras.- 4 tablas.- referencias.Due to the extended oil extraction and transportation in Russia and other oil-producing countries, many lands remain contaminated because of accidental spills. This situation requires the cost-effective and efficient remediation of petroleum-contaminated soils. Bioremediation of soils contaminated with high concentrations of crude oil is usually hampered by high toxicity thresholds for microbial degraders. We have performed a two-year microfield experiment on the influence of a mixed adsorbent (ACD) composed of granular activated carbon and diatomite on bioremediation of a grey forest soil contaminated with crude oil at concentrations (5–15 % w/w) that would theoretically not result in a successful pollutant removal due to toxicity. Remediation of these soils was evaluated after treating with the ACD adsorbent (from 4 to 12% w/w) and a biopreparation (BP) containing hydrocarbon-degrading bacteria, separately or in combination. Reduction of total petroleum hydrocarbons content was significantly greater in highly contaminated soils with the combined amendments than in the respective controls (through the activation of indigenous degrading microorganisms by fertilizing and mixing) by 9-10% and 5-8% at the end of the first and second years, respectively, depending on the contamination level. Significantly higher counts of petroleum-degrading microorganisms (as indigenous and introduced by the BP), as well as much less phytotoxicity was detected in the ACD-amended soils, as compared with the samples without adsorbent. In addition, the ACD mixture drastically reduced the wash-out of polar petroleum metabolites (evidently oxidized hydrocarbons) and the phytotoxicity of the lysimetric waters, especially in highly contaminated soils. The results indicate that the mixture of activated carbon and diatomite is a prospective adsorbent for the in situ bioremediation of soils highly contaminated with crude oil.This work was financed by the Russian Foundation of Basic Research (Project No. 16-05-00617).

Approbation of express-method for benzo[a]pyrene extraction from soils in the technogenic emission zone territories

The benzo[a]pyrene accumulation and migration regularities in chernozemic soils under the aerotechnogenic emission zone were revealed on the basis of long-term monitoring researches. A new method of subcritical water extraction has been developed for determination of benzo[a]pyrene from soils of the emissions zone of Novocherkassk Power Station one of the largest thermal power enterprises in Russian Federation. It is shown that the soils adjacent to a source of emission are polluted by benzo[a]pyrene at distance to 5 km. Trends in the accumulation of benzo[a]pyrene in soil zones of the thermal power plant influence have been researched over a 5-year period of monitoring observations. The assessment of soils pollution extent by benzo[a]pyrene is given
