Image Georeferencing using Artificial Neural Network Compared with Classical Methods
Authors: Ezz El Din Zahra 
Published: January 2022

Georeferencing process is one of the most important prerequisites for various geomatics applications; for example, photogrammetry, laser scan analysis, remotely sensing, spatial and descriptive data collection, and others. Georeferencing mostly involves the transformation of coordinates obtained from images that are inhomogeneous due to accuracy differences. The georeferencing depends on image resolution and accuracy level of measurements of reference points ground coordinates. Accordingly, this study discusses the subject of coordinate’s transformation from the image to the global coordinates system (WGS84) to find a suitable method that provides more accurate results. In this study, the Artificial Neural Network (ANN) method was applied, in addition to several numerical methods, namely the Affine divided difference, Newton’s divided difference, and polynomial transformation. The four methods were modelled and coded using Matlab programming language based on an image captured from Google Earth. The image was used to determine reference points within the study area (University of Baghdad campus). The findings of this study showed that the ANN enhanced the results by about 50% in terms of accuracy and 90% in terms of homogeneity, compared with the other methods.

STRUCTURAL AND SEMANTIC PECULIARITIES OF EMOTIONAL STATES VERBALISATION IN MODERN ENGLISH LITERATURE DISCOURSE (BASED ON THE NOVEL BY E. GILBERT ‘EAT, PRAY, LOVE’)
Authors: Zaluzhna Olha , Sokolova Vladyslava 
Published: January 2022

The article is devoted to the study of means expressing emotional states in modern English literature discourse, i.e., the novel by E. Gilbert ‘Eat, Pray, Love’. The paper outlines structural and semantic peculiarities of lexical means expressing emotional states based on 163 verbal constructions obtained by continuous sampling from the novel under analysis. Emotional and emotive vocabulary are two adjacent but not identical notions; the term ‘emotive’ belongs to the sphere of linguistics comprising multilevel lingual means of expressing emotions, i.e., a linguistic research focuses on emotive vocabulary where the verb plays a significant role as a meaningful centre of the sentence. Verbalisation of emotional states is performed synthetically (indication of the emotional state is incorporated into the verb semantics) and analytically (emotional state is expressed through an adjective or / and noun semantics which follow the link verb). Emotional states include means of positive, negative, and neutral states. Emotive vocabulary denoting positive emotions comprises 8 emotional states among which are love, gaiety, happiness, satisfaction, excitement, admiration, tranquillity, inspiration, with the units containing semantic component ‘love’ dominating this group and constructions denoting excitement, admiration, tranquillity, and inspiration demonstrating low productivity. Negative emotions include 7 emotional states: fear, grief, anxiety, anger, sadness, rage, anguish, where constructions denoting fear and grief demonstrate the highest productivity, and units denoting anxiety, anger, sadness, rage, and anguish show low productivity.

Therefore couples who are married try to have children because children are seen as important in the family. The value of children for family or parents in everyday life can be known, among others, from the fact that the child is a place where parents express love, children are a source of family happiness, children are often taken into consideration by a husband and wife to cancel the desire to divorce and also where parents depend various hopes. The purpose of this research is to describe psychological problems, life dynamics and the efforts made in maintaining family harmony without the presence of children. The research method uses a qualitative approach with a descriptive design while the research informants are taken by purposive sampling. The results of research on psychological problems found the fact the presence of a child is not the main factor of family harmony but there are still many other factors. Some of the efforts that a husband and wife can make in maintaining family integrity, the first is cooperation, the second is trying to please the couple, the third is adoption, the fourth is getting closer to religious activities. The benefits the results of this study are as a basis for implementing family counseling in handling family problems, especially family problems that do not have children.
Hipótesis sobre el (des)encuentro entre la investigación artística y la investigación científica.
Authors: Fuentes Cid Sara , Cordovil João L. 
Published: January 2022

Afortunadamente, la investigación artística se ha vuelto más aceptada por la academia en los últimos años y el potencial de una relación mutuamente beneficiosa entre Arte y Ciencia parece más prometedor que nunca. A pesar de ello, continúan existiendo tensiones y reticencias que obstaculizan excesivamente el desarrollo de proyectos interdisciplinares donde el Arte esté implicado.
En este artículo intentaremos, en primer lugar, analizar comparativamente la investigación artística y la investigación científica a la luz de cuatro dominios clásicos de la Filosofía de la Ciencia: lenguaje, mereología, método y verdad; en segundo lugar, formularemos dos hipótesis sobre (1) las razones del desencuentro persistente entre Arte y Ciencia, asentado en la separación entre racionalismo y empirismo y (2) sobre la posibilidad de encuentro, basado en el uso especulativo de la razón, entre la investigación artística y científica; dos miradas metodológicamente distintas sobre el mismo concepto o problema metafísico.
Fernando Falconí
Authors: Lusardi Giada 
Published: January 2022

El presente texto introduce el mas reciente trabajo del artista Fernando Falconí que se expuso desde el día jueves 12 de agosto hasta el día sábado 11 de septiembre de 2021 en el espacio N.A.S.A.(L) de Mauricio Aguirre en Guayaquil (Ecuador).
A lo largo de su trayectoria artística Fernando Falconí ha explorado sutil, irónica y agudamente los relatos científicos sobre la evolución de las especies y el desarrollo de la vida. De manera particular ha hurgado en la dinámicas reproductivas, reformulando preguntas respecto a la contradictoria relación entre el ser humano y naturaleza. Todo esto lo ha hilvanado dentro de la manera crítica con la cual se aproxima a los discursos (e incoherencias) sobre la nación, su cultura y educación. En esta nueva serie de obras (2019-2021), el artista propone un nuevo reto de interpretación, alineado a su trabajo previo, que propicia una reflexión y un cuestionamiento histórico respecto a cómo se organiza y transmite el conocimiento a nivel social.
Reflexiones en torno a lo tremendo desde el hacer-material de la obra de arte contemporánea
Authors: Hernández Parraguez Marta 
Published: January 2022

Este artículo se propone reflexionar sobre el concepto de lo tremendo y su vínculo con ciertas prácticas artísticas contemporáneas que reflexionan la relación entre técnica y violencia, desde la materialidad de sus recursos y procedimientos. La hipótesis que se desarrollará es que lo tremendo se deja nombrar en el arte en la medida en que ciertas obras y prácticas artísticas alteran la función comunicativa del lenguaje haciendo emerger sus propios recursos técnico-materiales.
A nivel metodológico, el texto ha sido estructurado en tres secciones: la primera corresponde a una reflexión acerca de la relación entre lo tremendo y la violencia de la técnica sobre el pensar; la segunda propone pensar la relación entre violencia y lenguaje a partir de la pregunta: ¿puede lo tremendo ser representado?; y, finalmente, una tercera sección en la que se ilustrará la hipótesis enunciada por medio del análisis de tres obras de artistas latinoamericanas.

Published: January 2022

The article highlights the results of research on assessing the ecological state of the land near the silt fields №1 and №3 of Bortnytska aeration station in the Zolochiv village community of Boryspil district in Kyiv region. The presence of previously recorded increased content of heavy metals in soils compared to the background content, both in terms of their gross content and the content of mobile forms was confirmed within the certain areas near the silt fields. For the elements-pollutants (Zn, Cu, Cr, Pb) at some points within the agricultural land, exceeding the values ​​of their gross content and the content of mobile forms (Zn, Cu) of the maximum permissible concentrations was recorded at 1.1-6.2 and 1.1 -2.6 times, respectively. The average values ​​of heavy metals content for floodplains (settlement) and agricultural land near silt fields indicate their prevailing values ​​for the latter in almost all elements, as well as exceeding the background values ​​and maximum permissible concentrations for the land where silt deposits were previously applied as fertilizers. Within the surveyed areas, soils are classified as unsalted, but the increased content of exchangeable magnesium may adversely affect soil fertility.
Increased mineralization and content of ammonium and nitrates in groundwater are observed near silt fields, which is obviously related to the impact of silt water and can lead to deterioration of groundwater quality in the area of ​​their transit and discharge, in particular within the village Gnidyn. The area of ​​land with an extremely dangerous pollution rate in terms of total heavy metal is about 300 hectares, with a dangerous pollution rate is 260 hectares, and the estimated damage from crop failure may be 1.65 million UAH/year and 0.3 million UAH/year respectively. Within the areas adjacent to the silt fields, the condition of soils, water resources, cultivated products and the health of the population should be constantly monitored, especially when using the polluted land for agricultural use or housing.
Effect of the irrigation regime of rise on soil oxidation-reduction status

Published: January 2022

During the cultivation of rice in the field for 3 months, the required water layer is maintained. In these conditions, there are the processes that lead to changes in the composition of organic and mineral components of the soil, namely: removal of easily soluble substances and mobile forms of nutrients, the dominance of reduction processes over oxidation ones. Irrigation of rice crops using drip irrigation also causes changes in salt and water-air regimes, which leads to the formation of salt bags and toxic salinization of the soil in a layer of 0-60 cm. The negative effect of drip irrigation is not so noticeable compared to flooding conditions and can be eliminated by observing crop rotation with the rate of the main crop not more than 50%.
The research was conducted during 2016-2020 in the territory of the Rice Institute of NAAS and its experimental farm (Skadovsk district, Kherson region), where the soil cover is represented by dark chestnut saline soil. The study of the effect of rice cultivation in flood conditions was carried out on a rice irrigation system with an area of ​​190 ha, and under drip irrigation - on a demonstration trail with an area of ​​4 ha. The oxidation-reduction status of the arable soil layer of rice crop rotations when rice growing, is seasonal. In the period of water layer maintaining in the field, in the arable layer reduction processes predominate, while after harvesting and checks draining the intensity of the reduction processes is moderate and decreases.
A model describing this process by the equation of a quadratic parabola was constructed. Growing rice under drip irrigation also reduces the oxidation-reduction soil capacity to negative values, but for a short period, which does not adversely affect the soil. The dynamics of this indicator in the conditions of drip irrigation is described by the equation of a quadratic parabola. Continuous monitoring of this process enables to evaluate the stability of fluctuations of the oxidation-reduction soil balance, which is important for assessing soil quality.
Modern approaches to treatment and recovery of secondary sludge of domestic sewage
Authors: Zorina O. V. , Mavrykin Y. O. 
Published: January 2022

For today, pollution of the environment, in particular of surface waters, has led to an environmental crisis in many countries of the world. One of the reasons for this is the use of outdated approaches to the treatment and recovery of sewage sludge. The article presents the results of the study of literary sources in order to analyze the proposals for the treatment of secondary sludge of domestic sewage in different countries. To neutralize sewage sludge, scientists consider the possibility of obtaining fertilizes under conditions of biosulfidogenesis during the dissimilation recovery of poorly soluble sulfates or the use of enhanced oxidation technology.
A new concept of domestic sewage treatment has also been proposed, which can solve the issue of sewage sludge control at the place of its forming. The main areas of sustainable sludge control are its use in agriculture as fertilizer and for the reclamation of devastated or degraded lands, as well as energy recovery by burning and alternative thermal methods such as pyrolysis, quasi-pyrolysis and gasification. It was established that the applicability of this or that technology of sewage sludge recovery depends on many local factors, in particular: productivity of sewage station; composition and methods of sewage treatment and its sediments; efficiency of sewage treatment plants; climatic zone of the sewage system location; availability of energy and material resources, etc.
Today, it is relevant to monitor the qualitative composition of sewage sludge, as well as soils and natural waters regarding pollutants that can be detected in the sewage of the corresponding settlement, in order to make operational decisions to control environmental risks, as well as conduct scientific research to improve recycling and recovery technologies for sewage sludge of various composition in agricultural systems, which will help to protect the environment against pollution and rational use of land.
