RECULTIVATED SOIL HETEROGENEITY: ECOLOGICAL ASPECT

Extracting minerals by the open method leads to the removal of the rocks to the surface which significantly disturbs natural processes in biogeocoenoses. After remediation activities anthropogenic biogeocoenoses are formed. In this biogeocoenosis on the rocks man-made soils are formed under the influence of environmental factors. Such man-made soils are called technozems

THE GENERAL METHODOLOGICAL PRINCIPLES OF COMBINED OPTIONAL ONLINE ENGLISH LANGUAGE TRAINING OF PRIMARY SCHOOL STUDENTS

The aim of the publication is to demonstrate the implementation of general methodological principles of optional elementary school online foreign languages learning on an example of a virtual course for students of the second and third grades.Methods. The methods involve pedagogical modeling and projecting; the experience of foreign and Russian methodists, teachers and researchers is analysed, generalized and adjusted to the modern realias.Results and scientific novelty. On the basis of the requirements of the state educational standard and interest of pupils in computer games, the author’s technique of the combined facultative educational activities integrated to training in English at elementary school is developed. Online training in the form of games (additional to the major classroom activities) gives a possibility of the choice of tasks interesting to children, studying the material at optimum comfortable and individual speed; it is possible to perform the tasks at home excluding the stressful situations that are specific to school examination, and allows pupils to master most effectively personal, metasubject and object competences. In general context of quality improvement of the general education, the modernization of educational process assumes not only justification of its new maintenance, but also restructuring of scientific and methodical support which has to meet essential needs of teachers and pupils, to facilitate access to necessary specific information. The lack of methodical base of creation of electronic distance resources for foreign-language education of younger school students has motivated the author to create own methodical concept of online training taking into account age of pupils. The complex of the general methodical principles is thoroughly considered; based on the general methodical principles, the proposed modular technique of the organization of an online class is created and implemented. Interactive blocks are described; these blocks are the component units of each module in the educational space of the educational portal LearningApps.org – technological base of an online course of a foreign language.Practical significance. The results of the diagnostic studies, showed in the article, suggest that the use of the proposed general methodological principles increase the percentage of the knowledge quality, promote the development of initial linguistic representations required to master at the elementary level of oral and written skills in a foreign language, enrich linguistic horizons of students. It contributes to the development of motivation to learn foreign Language, as well as the formation of such metasubject result as the ability to learn and plan their activities. Online environment gives the chance to synchronize the problem solution of providing the trainee with information and methodical material; facilitates search by a teacher of an optimum way of achievement of the practical pedagogical purposes.

Екологічний аспект просторової неоднорідності едафотопів техногенного походження

The dynamics of spatial heterogeneity of the pedozem site reclamation of the Nikopol manganese ore basin in Ordzhonikidze has been studied in terms of hardness. The ecomorphic analysis of vegetation of the section has been spent. The ordination of data of soil hardness has been realized by non-metric multidimensional scaling. The three-dimensional variant of multidimensional scaling has been applied. The types of distribution of hardness in the profile typical of studied soil have been distinguished. The relationship of varying the hardness of the soil and environmental factors has been set using phytoindicative scales. For receipt most rank correlation has been used matrix based on distance the Chao with indicators pre-standardized to the range 0-1. It was established that factors forming the first coordination axis of environmental space is change the hardness of the soil, depending on the depth of the soil layer. There is interconnected opposite dynamics of soil hardness in layers of 30 cm below the profile with indicators of layers lying above the selected block. The scales of hydromorph, solt regime, such a structure of the soil, when there are there are significant differences in the hardness of the soil above and below the level of 25 cm from the surface with the most significant values of the hardness of the surface layer determine the second dimension. The highest value in the formation of the third dimension by the predictor has scale of light. In the latter case, the hardness of the soil at 10–35 cm depth profile will be different from surrounding. Using the technique of spatial data analysis (PCNM) has been highlighted the spatial structure at different scale levels and defined processes their underlying. It was established the trophic of soil is important for the formation of large-scale components of soil heterogeneity. The inhomogeneities of detailed scale mark by salt soil regime, its acidity, content of digestible nitrogen forms, mode lighting and presence in the group of plant different gigromorfes.Досліджено динаміку просторової неоднорідності педозему ділянки рекультивації Нікопольського марганцеворудного басейну в м Орджонікідзе за показниками твердості.

Secular Changes in Mongolia: Shift in Tempos of Growth

The patterns of secular changes in children and adolescents of the city of Ulаan-Baatar in the Republic of Mongolia measured in 2010–11 by the authors and in the group of children observed by Uranchimeg in the same place in 19891 have been analyzed. Total number of the investigated children and adolescents from 9 to 17 years of age was 1351. The last survey was conducted in accordance with bioethical procedures. The program included standard anthropometric measurements, descriptive characteristics2 and pubertal stages evaluation3. Mean age of development of secondary sexual characteristics was calculated graphically. For most of the anthropometric indices significant differences between the Mongolian teenagers of two series of measurements were revealed. The patterns of secular changes in body size confirmed the interaction of »tempo and amplitude«4: significant changes in pubertal growth were observed with the same average values at 16–17-year old boys and girls. The increase in body circumferences observed in modern Mongolian schoolchildren was possibly based on the increase of body fat component, parallel to the global trend worldwide

Characteristics phetoplacental complex change in women with pulmonary tuberculosis, complicated by iron deficiency anemia

87 pregnant women have been examined, 57 of them had pulmonary form of TB, complicated by IDA (main group). The control group consisted of 30 conditionally somatic-healthy patients with physiological pregnancy. Changes in the parameters of erythron, increased metabolic acidosis, development of placental dysfunction (93%), violation of hemodynamics in the utero-placental-fetal basin, and low biophysical profile of the fetus were found. The main group patients received comprehensive anti-anemic, antihypoxic, detoxificative, antioxidant and membrane-stabilizing therapy. After the pathogenetic treatment, the general condition of  mother and fetus improved, e. g. the total index of biophysical profile of fetus in the pregnant women of the main group increased from (6.87 ± 0.18) points to (8.73 ± 0.12) points Women with pulmonary tuberculosis and iron-deficiency anemia require complex pathogenetic therapy, which significantly improves the erythron signs, fetal, newborn and general  mother’s condition

non linear behaviour of electrical parameters in porous water saturated rocks a model to predict pore size distribution

SUMMARY In this paper, two separate but related goals are tackled. The first one is to demonstrate that in some saturated rock textures the non-linear behaviour of induced polarization (IP) and the violation of Ohm's law not only are real phenomena, but they can also be satisfactorily predicted by a suitable physical-mathematical model, which is our second goal. This model is based on Fick's second law. As the model links the specific dependence of resistivity and chargeability of a laboratory sample to the injected current and this in turn to its pore size distribution, it is able to predict pore size distribution from laboratory measurements, in good agreement with mercury injection capillary pressure test results. This fact opens up the possibility for hydrogeophysical applications on a macro scale. Mathematical modelling showsthatthechargeabilityacquiredinthefieldundernormalconditions,thatisatlowcurrent, will always be very small and approximately proportional to the applied current. A suitable field test site for demonstrating the possible reliance of both resistivity and chargeability on current was selected and a specific measuring strategy was established. Two data sets were acquired using different injected current strengths, while keeping the charging time constant. Observed variations of resistivity and chargeability are in agreement with those predicted by the mathematical model. These field test data should however be considered preliminary. If confirmedbyfurtherevidence,thesefactsmayleadtochangingtheprocedureofacquiringfield measurements in future, and perhaps may encourage the design and building of a new specific geo-resistivity meter. This paper also shows that the well-known Marshall and Madden's equations based on Fick's law cannot be solved without specific boundary conditions
