NUMERICAL SIMULATION OF METHANE EMISSION FROM SUBARCTIC LAKE IN KOMI REPUBLIC (RUSSIA)
No full textDuring last decades, a special attention has been paid to methane emission from lakes [Bastviken et al., 2004; Wik et al., 2016 and etc.] as one of the significant sources of this important greenhouse gas to the atmosphere. However, attempts to simulate methane production and efflux at the air-water interface are scarce [Stepanenko et al., 2011; Tan et al., 2015a; Tan et al., 2015b] and models proposed so far need further validation using observation datasets. In this study, we use the 1D + numerical model LAKE [Stepanenko et al., 2011; Stepanenko et al., 2016]. The LAKE model was applied to a small subarctic lake in the Seida study site (Komi Republic, Russia) for identification of the key factors influencing the surface CH4flux and its concentration in the lake. We carried out a calibration of biogeochemical constants involving qualitative considerations of the character of biogeochemical and physical processes occurring in the lake and aiming at a satisfactory agreement with observations, performed by the University of Eastern Finland (UEF) [Lind et al., 2009; Marushchak et al., 2016]. Comparing our model calibration results to earlier studies suggest that the crucial parameter of the model – methane production rate constant (Pnew, 0) – has similar values for lakes of different types in high latitudes

Abstract
Introduction. Morphological changes of the cerebellar lobules are found in many congenital and acquired diseases of the cerebellum, but the information on the normal structure of the cerebellar lobules do not take into account the peculiarities of individual anatomical variability, sex and age characteristics.
Aim – to investigate anatomical variability and fractal dimension of the white matter of the human cerebellar hemispheres.
Material and methods. The study involved 100 cerebella of people of both sexes, who died of causes unrelated to brain pathology (20–99 years old). Parasagittal sections of the cerebellar hemispheres were investigated.
Results. On parasagittal sections number of main branches of white matter is very varied and depends on peculiarities of structure of the hemispheric lobules. It was found that there is individual variability of the structure of the human cerebellar hemispheres, namely white matter branching features. We described variants of the branching of the main branches of white matter of the human cerebellar hemispheres.
Fractal dimension of the white matter was determined. The white matter of the cerebellum is typical quasi-fractal structure that can be objectively described using fractal dimension. Fractal index of the white matter of the cerebellar hemispheres varies from 1.119 to 1.519; average fractal index is 1.370. Fractal analysis can be used as an objective morphometric criterion for the diagnosis of various diseases of the cerebellum and other structures of the central nervous system.
Conclusions. Described variants of the cerebellar lobules and fractal dimension can be used as criteria for modern diagnostic imaging techniques for the diagnosis of various diseases of the CNS. The data can be used as the basis for atlases of serial sections of the cerebellum.
Key words: human, cerebellum, fractal dimension, white matter, anatomical variabilit
Compendiums of knowledge associated with linguistic terminology and linguists: history, classification features, and genre polyfunctionality
No full textThe author explores the historical development of Ukrainian linguistic terminology within the framework of national terminography, lexicography, encyclopediography. The article reviews and analyses the academic references encomprassing 1) nationally specific and borrowed terms as well as concepts in traditional and emerging linguistics branches (e.g., the Dictionary of Linguistic Terms by Ye. Krotevych and N. Rodzevytch; Dictionary of Linguistic Terms by D. Hanych and I. Oliinyk; Dictionary of Modern Linguistics: Concepts and Terms; Modern Linguistic Dictionary by A. Zahnitko; Ukrainian. Concise Dictionary of Linguistic Terms by S. Yermolenko, S. Bybyk, and O. Todor; Modern Linguistics: Terminological Encyclopedia by O. Selivanova; The Ukrainian Language. Encyclopaedia; etc.), and 2) personalities of Ukrainian linguists (e.g., Ukrainian Grammar in Names by A. Zahnitko, M. Balko; Nizhyn Linguistics by N. Boiko, S. Zinchenko, A. Kaidash; etc.). The author systemizes and classifies encyclopedic works based on different criteria in the classical way (according to nature of information: domain, subject-specific, biographical, personal works; according to target audience: professional linguistics, student philologists, applicants, pupils; according regional focus of linguistic conceptions: the Nizhyn region, the Poltava region; according to article structure: alphabetical, alphabetical-and-clustered), as well as in the new way (syncretism of linguistic and encyclopedic genres: subject-specific linguistic-and-encyclopedic-and-biographic works, domain regional-and-biographic ones, subject-specific regional-and-biographic ones). The universal and specific principles of forming the definitional part of both linguistic-encyclopedic and encyclopedic articles include interpretation by an author, macro- and mini-discursive cross-references, hyperlinks, scholarly inter-texts, novelty, debatable issues personal and bibliographic remarks, and global linguistic experience

No full textAbstractPhoton stimulated reaction of chlorine at ZnSe surface was observed at room temperature in the photon range from 4 eV to 12 eV. Estimated quantum efficiency is about 1, depending on the photon range and gas pressure. The study of reaction products was performed with AES, XPS and SEM with Energy Dispersion Analysis. A model based on photon stimulated diffusion of dissociated gas atoms is dicussed. Comparison to C12/GaAs and XeF2/Si systems was made.Effective laser ablation of the ZnCI2 films deposited with masks was exploited for direct patterning. The ultimate resolution obtained was restricted with diffraction limit,</jats:p
