El presente artículo se propone indagar en torno al espacio del discurso jurídico. El análisis no solo plantea un estudio de la disposición estructural que adoptan los enunciados en términos formales sino la funcionalidad que proyectan en el ámbito social. Desde las propuestas metodológicas que ofrecen los estudios de las teorías críticas del derecho, se pretende indagar sobre determinadas categorías que sustentan la constitución y despliegue del discurso jurídico.
Contrario a examinarlo como un saber aislado, consideramos necesaria una desconstrucción de los enunciados jurídicos a los fines de poder entrever la injerencia de otros discursos en su producción y los diferentes niveles en lo que intervienen las/os actoras/es jurídicas/os como la sociedad en general. Asimismo, cuestionar los pliegues y reversos de una justicia, que se piensa articulada meramente en un orden normativo, examinar los entramados ideológicos y visibilizar la participación de los dispositivos de poder en la conformación del imaginario social.
Assessment of Soil Electrical Properties in Selected Agricultural Soils of Puchuncaví, Central Chile
Authors: Alekseev Ivan , Abakumov Evgeny 
Published: July 2020

Abstract
Precision agriculture requires a wide sampling procedure to determine the spatial variability of soil properties for adequate assessment of soil state and appropriate recommendations. Electrical geophysical methods (i.e. vertical electrical resistivity sounding) allow performing rapid measurement of soil electrical properties directly from the soil surface to any depth without any mechanical disturbance of soil cover. Soil electrical properties are linked with many soil properties and could improve the quality and spatial coverage of soil surveys. The results obtained in our study using vertical electrical resistivity sounding confirmed the hypothesis of a high correlation between electrical resistivity and such soil properties as carbon and nitrogen content and silt content. The highest correlation (r > 0.9) was found for electrical resistivity and carbon content. It was also confirmed that significant correlations between electrical resistivity and soil properties are found mainly when soil properties are highly ranged. Perspectives for the applied method lie at the relationship between electrical resistivity and soil properties, such as texture class, clay content, carbon content, and cation exchange capacity. The results obtained in this work could be useful for complex precision agriculture, creating maps of agricultural soils, adequate methods of plant growth, and other issues of precision and conventional agriculture.

Abstract
Recycling systems aboard spacecraft are currently limited to approximately 80% water recovery from urine. To address challenges associated with odors, contamination, and microgravity fluid flow phenomena, current systems use toxic pretreatment chemicals, filters, and rotary separators. Herein, a semipassive and potentially contaminant- and biofouling-free approach to spacecraft urine processing is developed by combining passive liquid–gas separation, nanophotonic pasteurization, and noncontact Leidenfrost droplet distillation. The system aims to achieve >98% water recovery from wastewater streams in zero, Lunar, Martian, and terrestrial gravitational environments. The surfaces of the phase separator are coated with carbon black nanoparticles that are irradiated by infrared light-emitting diodes (LEDs) producing hyperlocal heating and pasteurization during urine collection, separation, and storage. For the prescribed flow rate and timeline, the urine is then introduced into a heated 8.5-m-long helical hemicircular aluminum track. The low pitch and the high temperature of the track combine to establish weakly gravity-driven noncontact Leidenfrost droplet distillation conditions. In our technology demonstrations, salt-free distillate and concentrated brine are successfully recovered from saltwater feed stocks. We estimate equivalent system mass metrics for the approach, which compare favorably to the current water recovery system aboard the International Space Station.

Pakistan-Ukraine. Analogies in the Triangles of Regional Security Complexes
Authors: Kotlyar Yuriy , Lymar Marharyta , Tykhonenko Iryna 
Published: July 2020

The paper deals with two countries – Pakistan and Ukraine – that are located at the center of the following two interest triangles: India-Pakistan-Afghanistan (South Asia) and Russia-Ukraine-Moldova (post-Soviet regional security complex). Despite their considerable differences, they have similar problems with their geopolitical neighbours in the context of territorial conflicts. Existing issues with neighbouring countries give Pakistan and Ukraine the status of a ‘middle state’, which is characterized by threatening its territorial integrity and becoming an object of ‘penetrating’ into its RSC (regional security complex) for the states from neighbouring regions.
Assessment of water resources of the Ukrainian rivers according to the average statistical models of climate change trajectories RCP4.5 and RCP8.5 over the period of 2021 to 2050

The relevance of the presented work is due to the necessity of assessment of a possible state of Ukrainian water resources in the 21st century according to climate change scenarios in order to justify the strategy of economic development.
The research object is presented by water resources of the Ukrainian rivers.
The research focuses on the effects of global warming on Ukrainian water resources in 2021-2050.
The work aims at assessing a possible impact of climate change on Ukrainian water resources in the 21st century, using the data from the climate change trajectories RCP4.5 and RCP8.5 over the period of 2021 to 2050.
Calculations of water resources over the period of 2021 to 2050 are performed according to the average statistical model from the ensemble consisting of 14 climatic models of the CORDEX experiment for the RCP4.5 and RCP8.5 trajectories. Water resources are assessed based on the Climate-runoff model developed by OSENU. The result of such calculations is the evaluation of moisture and heat resources, as well as water resources in the natural conditions of their formation. Natural (undisturbed by water management) average long-term annual runoff determined by the meteorological data is usually called "a climatic runoff". The accuracy of climatic runoff calculations using the map of isolines is ±10%. The calculations are performed in the grid nodes. The geographical location of the selected nodes corresponds to the location of meteorological stations the total number of which is 115.
Evaluation of heat, moisture and water resources changes was performed by comparing the calculated values and the basic ones. The climatic runoff for the period of observations before 1989 is thought to be basic.
According to the average statistical model of the RCP4.5 trajectory over the period of 2021 to 2050, the expansion of the semi-arid zone and insufficient humidification zone to the north is to be expected (when compared to the basic period). The insufficient humidification zone will expand to the northwest displacing the sufficient humidification zone. The reduction of water resources will reach to minus 40-50% in the south of the country and to 0% - minus 10% in the north. The area of water resources growth will be preserved in the Ukrainian Carpathians.
Comparing to the RCP4.5 the RCP8.5 trajectory is considered to be more “rigid” in relation to the state of Ukrainian water resources. The reduction of water resources will occur on the nearly entire territory, except Bukovyna, due to the increase of arid climate. Water resources will decrease to minus 50-60% in the south and to minus 30% in the north.
Both RCP4.5 and RCP8.5 trajectories offer a forecast of water resources that is unfavourable for the development of Ukrainian economy, as it will cause expansion of both semi-arid and insufficient humidification zones. This will increase the water resources shortage in Ukraine.
Forecasting sea level fluctuations caused by storm winds at the ports in Odesa Region of the north-western part of the Black Sea

Published: July 2020

Increasing the draught of ships that may be accepted by ports for loading at their loading berths is one of the main tasks aimed at development and freight turnover enhancement of sea trade ports located in Odesa Region of the north-western part of the Black Sea (cities of Chornomorsk, Odesa and Pivdennyi). An operational forecasting of short-term sea level fluctuations caused by storm winds presents a critical task for ensuring safe navigation across the ports’ water area and approach channels. The article is devoted to analysing and discussing the results of tests of a simplified 2D hydrodynamic model designed for forecasting such phenomena as upsurge and downsurge of the sea level caused by storm winds in the vicinity of sea ports in Odesa Region of the north-western part of the Black Sea. Spatio-temporal variability of wind conditions at the sea-to-atmosphere boundary was set based on the data retrieved from a 10-day synoptic forecast using global atmospheric prediction model GFS (Global Forecast System). The study analyses the results of forecast of significant (the ones exceeding 30 cm) short-term sea level drops and rises at the ports which were observed in 2016, 2017 and 2020.
It was established that, in case of use of the GFS forecast data, the pattern of sea level denivellations caused by storm winds and their amplitude in the majority of events start approximating to the observed values provided the forecast has a 4-day lead time. Therefore the accuracy of wind conditions variability forecast with application of the GFS model having a longer lead advance time is not sufficient for forecasting the sea level fluctuations caused by storm winds. The study made it possible to get an acceptable equivalence between the values of sea level denivellation amplitudes which were forecast with a 1-to-3-day lead time and the ones observed afterwards. In particular, when the forecast lead time is equal to »2 days, in relation to the expected storm conditions, the average absolute error for the forecast of sea level fluctuations amplitude constituted 7-8 cm, while its permissible value was defined as 15 cm, and the average relative error – 16-18%. It allowed making a conclusion that a hydrodynamic model option, applied alongside with the forecasting information on wind conditions variability retrieved with the help of the GFS weather prediction model, may be used for operational forecasting of short-term sea level fluctuations caused by storm winds with the forecast lead time of up to 4 days.
Sorption of nickel (II) and manganese (II) ions from aqueous solutions

Published: July 2020

Mine water from non-ferrous metal deposits is often contaminated with nickel and manganese ions. The entry of these ions, especially nickel, into surface waters and underground aquifers is undesirable since it has a negative effect on living organisms and worsens the condition of drinking water sources. One of the promising methods for selectively extracting nickel ions and obtaining an eluate suitable for further use is sorption by weakly acid cation exchangers with chelate groups of iminodiacetic acid.
As part of the study, sorption isotherms of nickel and manganese ions by Lewatit MonoPlus TP 207 cation exchanger in mono- and bicomponent systems were obtained. In monocomponent systems, the maximum static exchange capacity (SEC) of the cation exchanger for nickel ions is 952 mmol/dm3, and in bicomponent systems – 741 mmol/dm3; for manganese ions– 71 mmol/dm3 and 49 mmol/dm3, respectively. It is obvious that the studied cation exchanger has a greater capacity for nickel ions than for manganese ions.
The influence of a temperature increase from 300 to 330 K on the sorption of nickel and manganese ions was established: in monocomponent systems, the maximum degree of extraction of the former increases from 65 to 77 % (SEC from 337 to 399 mmol/dm3), and the latter from 21 to 35 % (SEC – from 140 to 229 mmol/dm3); in bicomponent systems, the extraction of nickel ions increases from 59 to 78 % (SEC – from 307 to 429 mmol/dm3), and manganese ions decreases from 20 to 17 % (SEC – from 164 to 131 mmol/dm3). The predominant increase in the indicators is due to the filling of the sorption centers of the ion-exchange resins, which are energetically unfavorable for the exchange of counterions at a lower temperature.
The influence of the pH of the solution on sorption was determined: the intensification of the process for nickel ions is observed in the pH range of 8.0-8.5 in a monocomponent solution and 8.0-9.0 in a bicomponent solution, for manganese ions in the range of 8.0-9.5 in both cases. The increase in the degree of extraction of ions and the exchange capacity of the ion exchanger with increasing pH is associated with the appearance of singly charged hydroxocations, dissociation of the functional groups of the sorbent and, to some extent, with the subsequent formation of insoluble forms of nickel and manganese. However, with increasing pH, a decrease in the selectivity of nickel extraction is observed: the ion separation coefficient decreases from 14.0 to 6.0 in the pH range of 6.0-11.0.
