FRACTAL PROPERTIES OF MICROPLASMA BREAKDOWN AND STRUCTURAL HETEROGENEITY OF SEMICONDUCTOR MATERIALS
This work presents experimental results on the study of current-voltage characteristics and oscillograms of microplasma pulses of the p-n-junction avalanche breakdown. Based on the latter, the pulse duration distributions are determined. As a result, it is shown that microplasma noise has fractal properties. The latter form the basis of avalanche breakdown types developed classification. The correlation between the fractal dimension of microplasma noise and structural inhomogeneities of functional semiconductor structures is revealed
Russia's contribution to regional geologic mapping of Venus
Geologic maps in Magellan C1-format were produced by six geologists and three cartographer in Russia during 1992. More sheets are in progress. The work is coordinated by Vernadsky Institute. The Magellan SRR images in form of C1-format photomaps were used as a base for geologic-geomorphic regional mapping of Venus at approximately 1:8,000,000 scale. This work took place in Russia at Vernadsky Institute and at the Department of Geology, Lomonosov Moscow University. The aim is to produce a preliminary geologic survey of Venus with the new high resolution images obtained by Magellan. It took place at the cartographic division, Laboratory of Comparative Planetology and Meteoritics, Vernadsky Institute, Russsia's Academy of Sciences
Beverages and Desserts With Therapeutic and Prophylactic Properties Based on Alginate-Containing Biogel From Laminaria -- ``Vitalgar Cardio''
In this research, recipes were developed for beverages and desserts based on ”Vitalgar Cardio”, abiogelthat contains alginate, has therapeutic and prophylactic properties, and was produced from laminaria at the SPC ”Vita-Li” LLC. ”Vitalgar Cardio”, in its liquid form, as well as desserts based on it, is a source of soluble dietary fiber (alginates) and chemical elements such as potassium, magnesium and iodine, and is an adsorbent of various toxins, including radionuclides and heavy metals. The developed products have traditional appeal, with a focus on healthy nutrition, which is currently being promoted among the population.

Assessment of students’ professional competencies – the future teachers of mathematics
The aim of the investigation is to describe the authors’ approach to the assessment of the professional competence of the future teacher of mathematics. Methods. The methods involve comparative analysis of the Professional Standard of the teacher and the Federal State Educational Standards in teacher education, as well as the method of predictive analysis of modern educational situation. Results. Qualimetric approach to the structuring of the professional competencies of students is described; it allows concretizing the assessment object, to select the criteria and levels of its formedness, to trace the dynamics of development in the medium of profile preparation of a bachelor. The methodology of assessment a professional-profile competence of the future mathematics teachers is proposed; examples of the competence-assessment tools are provided. Scientific novelty. The study gives a detailed analysis of developing the innovative approach to competencies assessment as metasubject learning outcomes. Practical significance. The proposed method of competencies assessment can be used in the mathematical preparation of the future mathematics teacher, and can serve as a basis for monitoring the professional competencies of studentsЦель публикации – описание авторского подхода к оцениванию профессиональных компетенций будущего учителя математики. Методы. В представленном в статье исследовании применялись метод сравнительного анализа профессионального стандарта педагога и федеральных государственных образовательных стандартов по педагогическому образованию, а также метод прогностического анализа развития современной образовательной ситуации. Результаты. Рассмотрен квалиметрический подход к структурированию профессиональных компетенций студентов, который позволяет детализировать объект измерения, выделить критерии и уровни его сформированности, проследить динамику его развития в сфере профильной подготовки бакалавра. Описана методика оценивания одной из профессионально-профильных компетенций будущего учителя математики, приведены примеры компетентностно-оценочных средств. Научная новизна выдвигаемых идей заключается в разработке инновационного подхода к оцениванию компетенций как метапредметных результатов обучения студентов педагогических специальностей. Практическая значимость. Предлагаемая методика оценивания компетенций может быть использована в процессе подготовки будущего учителя математики и может служить основой мониторинга качества подготовки студенто
Природа та характер семантичної деривації в термінології будівельного машинобудування (Nature and peculiarities of semantic derivation in machine building terminology)
Комплексно проаналізовано назви будівельних машин і механізмів, які утворені семантичним способом. Виявлено
і описано механізми семантичного перетворення, що діють в сфері термінолексики будівництва. Розглянуті термінисемантичні деривати формують три групи, які утворюються внаслідок когнітивної метафоризації загальновживаних слів або перейшли з інших терміносистем.
(The machine building terms formed by semantic way have been analyzed. The semantic transformation ways acting in
machine building terminology have been defined and described. It has been found out that the terms – semantic derivatives form three groups due to a cognitive metaphor formation way on the level of vocabulary that is in general use. Some terms became members of analyzed terminology in a process of metaphoric functional transfer of meanings from other term systems.
Формування і становлення галузевої термінології в когнітивному аспекті
У статті розглядається проблема використання когнітивного підходу у дослідженні термінології, питання
термінологічної номінації в когнітивному та прагматичному аспектах, в контексті екстралінгвальних факторів,
що впливають на її формування.
(The problem of cognitive approach to investigation of terminology, questions of terminological nomination in cognitive and pragmatic aspects have been considered in this paper. Some extra linguistic factors influencing the term formation have been analysed.
Relief and geology of the north polar region of the planet Venus
Description of topographic features is given for the North polar region of the planet Venus. Principal geomorphic types of terrain are characterized as well as their geologic relations. Relative ages of geologic units in Venus North polar region are discussed
Inclusion of beta-carotene in various courses of chemotherapy of lympholeucosis L1210
Possibility of including of synthetic beta-carotene in variuos courses of chemotherapy of lympholeucosis of mice BDF1 was investigated. In experimental models cyclophosphan and platidiam (50, 100, 200 and 8 mg/kg b.w. respectively) was used as anticancer drugs. Beta-carotene (5, 10, 20, 50 mg/kg b.w.) was administrated to mice in different schemes. During experiments it was observed that beta-carotene does not effect the rapeutic action of cyclophósphan and platidiam during treatment of lympholeucosis L1210
Molecular identification of streptomycin monoresistant Mycobacterium tuberculosis related to multidrug-resistant W strain.
A distinct branch of the Mycobacterium tuberculosis W phylogenetic lineage (W14 group) has been identified and characterized by various genotyping techniques. The W14 group comprises three strain variants: W14, W23, and W26, which accounted for 26 clinical isolates from the New York City metropolitan area. The W14 group shares a unique IS6110 hybridizing banding motif as well as distinct polymorphic GC-rich repetitive sequence and variable number tandem repeat patterns. All W14 group members have high levels of streptomycin resistance. When the streptomycin resistance rpsL target gene was sequenced, all members of this strain family had an identical mutation in codon 43. Patients infected with the W14 group were primarily of non- Hispanic black origin (77%); all were US-born. Including HIV positivity, 84% of the patients had at least one known risk factor for tuberculosis
