WIND FACTOR IN SPATIAL AND TEMPORAL DYNAMICS OF WIND EROSION WITHIN VOLYN REGION
Authors: Matviychuk B. , Matviychuk N. 
Published: March 2023

The analysis of the wind factor as a factor of wind erosion of Polissia soils is highlighted. The highest intensity of wind erosion in the Polissya zone is observed in the spring and autumn periods, when the density of vegetation cover is the lowest during the year and there is no snow cover. The temporal dynamics of the wind regime forms certain patterns, which determines the formation of the corresponding clusters of months of the year as indicators of the temporal regularity of the wind regime and clusters of administrative districts as indicators of the spatial regularity of the wind regime. The early spring period is the least long (two months), which allows it to be interpreted as transitional. This interpretation explains the inclusion in this cluster by the dynamic features of August as also the transition period from the summer wind regime to the autumn one. The winter period is characterized by an extremely strong wind regime, the lowest wind intensity is observed in the summer-autumn period. The transitional early spring period is characterized by an intermediate level of wind load, but the greatest variability of indicators, which also emphasizes the transitional nature of this time stage of the year. It was established that the maximum value of the wind factor for these areas is observed in winter and is 3,57 m3 s−3, and the minimum is observed in August and is 2,3 3,57 m3 s−3. The central and eastern regions (Manevytskyi, Kovelskyi and Rozhishchenskyi) also form a homogeneous subzone, the peculiarity of which is that the duration of strong winds in the winter period is somewhat shorter compared to the northwestern regions. The highest wind load is observed in the winter months, and the lowest at the end of summer. Geographically, the north-western and south-eastern regions of the region experience the greatest wind load. In terms of time, three consecutive periods can be distinguished: winter, early spring, and summer-autumn.
NEW FINDINGS OF THE NAKED FILOSE AMOEBAE IN NATURAL BIOTOPES OF UKRAINE
Authors: Patsyuk M. 
Published: March 2023

We have identified 10 species of naked filose amoebae in different types of water bodies in Ukraine. Original morphological descriptions have been compiled for all species. The most common species are Arachnula impatiens, Penardia mutabilis, Nuclearia delicatula, Biomyxa vagans, Vampyrellidium perforans, Nuclearia flavocapsulata, the least common are Vampyrella lateritia, Lateromyxa gallica, Leptophrys elegans, Leptophrys vorax. Established ecological groups of these protists in relation to the abiotic factors of the aquatic environment: euryoxidic (N. delicatula, N. flavocapsulata, A. impatiens, P. mutabilis, L. elegans, L. vorax, V. lateritia), stenooxidic (V. perforans, B. vagans, L. gallica), stenobionts (A. impatiens, V. perforans, B. vagans, L. gallica) and those that withstand a wide range of permanganate oxidation values (N. delicatula, N. flavocapsulata, P. mutabilis, L. elegans, L. vorax, V. lateritia). The largest number of species of these protists is observed in rivers (8 species) and floodplains (7 species), the smallest – in swamps (3 species); 5 species of filose amoeba were found in the lakes. We encountered P. mutabilis only in rivers, B. vagans in swamps, and V. perforans in floodplains. L. elegans, L. vorax species, which can be considered eurytopic, occurred in all types of reservoirs. The largest share of common species of naked amoebas is observed between rivers and floodplains (0.80), rivers and lakes (0.77), floodplains and lakes (0.67) and lakes and swamps (0.50), the smallest – between floodplains reservoirs and swamps (0.40) and rivers and swamps (0.36). According to the species composition of naked filose amoebae, two species complexes are distinguished: swamp and floodplain, which includes species that mainly occur in rivers and in reservoirs located in river valleys. The species complexes of rivers, floodplains and swamps are influenced to a greater extent by water temperature and the concentration of organic substances dissolved in water, and to a lesser extent by the concentration of oxygen dissolved in water. The species composition of naked filose amoebas of rivers and floodplains is associated with a higher temperature and a higher content of organic substances dissolved in water compared to the species composition of swamp amoebas.
PHYTOPLANKTON PRIMARY PRODUCTIVITY
Authors: Shcherbak V. , Korniychuk N. 
Published: March 2023

Primary productivity is an important integral parameter describing energy potential of aquatic organisms’ vital activity. Primary productivity determines the quality of water environment, its self- purifying capacity – from the Global Ocean to various continental ecosystems (Odum 1953, Williams et al. 2002, Bott et al. 2006, Kuehl and Troelstrup 2013).
Primary productivity is a bioenergy process transforming the solar energy into the energy of chemical bonds in organic matter, newly synthesized by the autotrophic link. The autotrophic link is mainly formed by algae from different ecological groups (phytoplankton, phytobenthos, phytoperiphyton) and higher aquatic plants.
As any process of energy production and transition, primary production in aquatic ecosystems is regulated by the laws of thermodynamics: the first law – the Lomonosov-Lavoisier law, the second law – the entropy law (Odum 1953). It is necessary to state clearly, that green plants do not transform the total amount of the Sun’s radiant energy, but only a part of it, within the spectral range between 480 and 720 nm (within the wavelength band of photosynthetically active radiation).A simplified equation describing the primary production process can be represented as follows:Proceeding from the above equation, primary productivity may be considered equivalent to (analogous to) the photosynthesis intensity.
There is a range of various methods for estimating PP: according to algal cell number, according to nutrient dynamic in water, according to diurnal dynamics of dissolved oxygen, according to chlorophyll a content, light-and-dark bottle method in oxygen or radiocarbon modification. With consideration taken of these methods’ advantages and disadvantages, researchers will be able to obtain the most reliable and unbiased primary productivity data.
MULTIDISCIPLINARY APPROACH TO THE PROBLEM OF SMALL RIVERS PROTECTION IN ZHYTOMYR POLISSYA
Authors: Semeniuk M. , Demchuk N. , Kozyn M. 
Published: March 2023

The article is devoted to the study of the complex problems of the preservation of small rivers. Three main aspects of the environmental impact associated with them are considered: disruption of the water balance, reduction of water quality, and reduction of biotic and landscape diversity in the river valley. The study aims to characterize the main types of human impact on the small rivers of Zhytomyr Polissia. To achieve the goal, the following tasks were set: determine the main types of anthropogenic impact on small rivers of Zhytomyr Polissia; to determine the direct and indirect consequences of certain types of anthropogenic impact on small rivers of Zhytomyr Polissia; develop proposals for algorithms for solving the problems of small rivers of Zhytomyr Polissia.
The article is based on the materials of the survey of the ecosystem structure of small rivers of Zhytomyr Polissia and its southern outskirts. Examples of the conservation plan for the catchment area of the «Gudyucha krynytsia» natural spring and the section of the Uzh River in the city center of Korosten are given. According to the results of the survey of the state of small rivers, we will summarize their main problems into three groups: low and unstable water flow, eutrophication and siltation, and degradation of river valley landscapes. The low filling of rivers with water and its unstable level is caused by the specifics of climate changes, natural mechanisms of water accumulation, distribution, and flow, and the activity of natural sources. Natural safeguards could weaken the problems of small rivers: swamp-forest complexes and natural springs near the sources of rivers, a high share of forest ecosystems of the upper part of the river basin, preservation of floodplain forests of the first floodplain terrace of the upper reaches and natural riparian forests and floodplain meadows of the lower reaches, as well as the integrity of the natural vegetation cover of most of the river valley. In order to stabilize the supply of water from natural sources to the river, the territories of their catchment should be transformed into objects of the nature reserve fund. When the spring is located within the boundaries of the settlement, it is advisable to grant it the status of a natural monument of local importance. When it is outside its borders, it should be given the status of a hydrological reserve.

Published: March 2023

The second half of XX century – the beginning of XXI century are characterized by the active development of a global ecological crisis, which is described by a critical state of the environment and excessive anthropogenization of a geographical sphere. The changes which lead to the formation of absolutely new techno-genic landscapes occur at very fast rates in current geo-spheres. The purpose of the work is to substantiate the recognition of a new geo-sphere – a landscape techno- sphere – based on the previous experience and our field research. The main tasks of the research are to analyze specific features and properties of a landscape techno-sphere; to identify its upper and lower borders; to study a structural organization of all options of a landscape sphere with available techno-substances; to characterize briefly the main stages of the development of a techno- sphere.
The research of a landscape techno-sphere is a complicated process and it is based on the use of classical and innovative methodological principles of contemporary geography. A parallel application of three scientific paradigms is the foundation: system, model and ecological. They do not contradict each other; they rather compliment the studying of the interaction between nature and engineering. A system approach allows considering a techno-sphere as a complicated system of a lower taxonomic range of a landscape sphere and a geographical sphere. The following generally accepted scientific methods are used in the paper: analysis, synthesis, comparison, generalization, systematization, induction and deductions.
The article substantiates the existence of a new geosphere – the landscape techno-sphere, which is formed by the planetary set of landscape-technical systems. it is noted that it does not have a continuous distribution, but is constantly increasing in size and gradually goes beyond the landscape. The specific features and properties of the landscape techno-sphere are analyzed in detail. Taking into account the criterion of the presence of a zone of direct contract of three blocks of landscape-technical systems (managerial, technical and natural), the upper and lower limits of the landscape techno-sphere are identified. The structure of all variants of the landscape sphere in the presence of technological substances is considered. The main periods of development of the landscape techno-sphere are briefly described. It is concluded that man will never be able to control landscape-technical systems on a planetary scale. However, applying the methods and principles of engineering landscape research, it is possible to achieve optimal interaction of the three blocks of landscape-technical systems and to extend their functional suitability.
Hígado graso no alcohólico y consumo de fructosa: revisión y actualización de la evidencia
Authors: Gobea Alcoba Anabella , Crespi Maria Florencia 
Published: March 2023

El hígado graso no alcohólico (HGNA) es actualmente una de las principales causas de enfermedad hepática crónica. Se define como la presencia de esteatosis en ausencia de otras causas de enfermedad hepática crónica y su prevalencia aumenta en todo el mundo. Se ha sugerido que existe una relación causal entre el aumento de la prevalencia de HGNA y la ingesta de edulcorantes nutritivos, en particular de fructosa. El objetivo general de esta revisión es describir la asociación entre el hígado graso no alcohólico y la fructosa en humanos.
Se realizó una búsqueda de artículos científicos con palabras clave. Los resultados de esta revisión describen que el consumo de fructosa se ha incrementado en las últimas décadas, principalmente a partir de la ingesta de sacarosa y jarabe de maíz de alta fructosa (JMAF), edulcorante de uso común en la industria alimentaria. El consumo crónico de fructosa promueve una serie de mecanismos que aumentan la lipogénesis hepática. Esta tasa de síntesis supera la tasa catabólica de oxidación de ácidos grasos y la capacidad de exportación como VLDL, que contribuye de manera importante a los lípidos intrahepáticos en el HGNA.
El manejo inicial del HGNA implica, principalmente, recomendaciones de alimentación como disminución del consumo de azúcares libres, patrón de dieta mediterránea y cambios del estilo de vida para lograr la pérdida de peso; sin embargo, la evidencia es limitada y se necesitan grandes estudios prospectivos y ensayos controlados que evalúen la relación entre la fructosa y el HGNA.

<p style="text-align: justify;">Pemikiran mendalam tentang permasalahan terkait pendidikan memiliki tujuan yang mulia yakni memperbaiki tatanan pendidikan hingga ke akar-akarnya hingga tercapai pembentukan manusia bermanfaat bagi diri sendiri, orang lain, dan lingkungannya. Catatan sejarah dalam filsafat barat semula pendidikan seluruhnya diserahkan kepada gereja yang pada perkembangannya memunculkan pemikiran dengan mengedepankan sikap proaktif yang memisahkan antara sain dan agama, hingga muncul para filsof barat dengan pemikirannya bahwa segala sesuatu yang terjadi di dunia ini adalah gerak materi yang berimplikasi bahwa dunia pendidikan adalah gerak pikiran di otak dari hasil dari peristiwa di dunia fisik. Sedang pada pemikiran Islam bahwa pendidikan berakar dari Alquran dan Hadist yang menyatukan serta mendamaikan antara sain dan agama, menjadikan nilai-nilai agama sebagai landasan dalam pengembangan ilmu pengetahuan guna mencapai puncak fitrahnya sebagai manusia hingga tercapai kebahagiaan, ketenangan, kedamaian dan keselamatan di dunia akhirat. </p>

Nas comunidades indígenas todo espaço é escola, toda atividade cotidiana é incorporada à educação. A reflexão tem como objetivo geral compreender a trajetória sócio-histórico-jurídica de dominação com vistas ao processo de colonialismo e decolonialismo para os povos indígenas na conquista plena de seus direitos, em especial, o direito à educação escolar. Os objetivos específicos são: I) analisar o processo colonialista etnocentrista que inviabilizou e dominou os povos indígenas na América Latina e no Brasil; II ) Abordar a base legislativa internacional e nacional educacional intercultural; III) diferenciar a educação indígena e a educação escolar indígena e a concepção de conhecimento ; IV) formação do professor e do currículo da educação escolar indígena. O procedimento metodológico utilizado foi o bibliográfico-investigativo, acrescido de coleta de dados em bancos estatísticos. Utiliza-se também da análise de documentos jurídicos e legislativos. É possível observar que todo o aprendizado indígena, baseando-se na reciprocidade, deve ser útil e promover o bem-estar da comunidade. Diante da diversidade dos povos a educação deve ser intercultural, bilingue e desenvolvida em conjunto com a comunidade, desde a escolha do professor que deve compreender os valores e a cultura da comunidade. Conclui-se que, a educação e o ensino intercultural escolar é a maneira de tornar o indígena protagonista, desvinculando-o do colonialismo.
