Consolidar la oferta estatal hortícola exportable y la comercialización directa con cadenas de supermercados: propuesta para Sinaloa
Authors:   Universidad Autónoma de Sinaloa, Gaxiola Carrasco Héctor Enrique
Published: June 2023

El motivo central del presente trabajo es proponer una red de comercialización en Estados Unidos para las hortalizas sinaloenses, que sea directa con supermercados, tiendas detallistas, etc., mediante una distribuidora propia de sinaloenses —sociedad entre actuales distribuidores y productores que no posean distribuidoras y con personal clave de ventas y administración—, para consolidar la oferta estatal mediante la certificación de inocuidad alimentaria para toda la producción. Ello implica la reubicación de la estación de ferrocarril, para que en su nuevo sitio se establezca una importantísima alternativa ferroviaria denominada “transporte multimodal para distancias corta” para facilitar ventas directas, incluso a cadenas de supermercados.
La economía ambiental y la economía ecológica: dos paradigmas complementarios
Authors:   Universidad de Guadalajara, Peniche Camps Salvador
Published: June 2023

No hay mejor política ambiental que una buena política económica. Tal parece ser el fundamento del acercamiento al estudio de los problemas ambientales desde la perspectiva de la ciencia económica. En este sentido, el trabajo que se presenta pretende aportar elementos para situar el debate sobre la utilidad de las dos corrientes fundamentales que abordan la problemática del estudio de la relación entre la economía y el medio ambiente: la economía ambiental y la economía ecológica. En la primera parte se plantea la particularidad del estudio del medio ambiente desde la perspectiva de la economía neoclásica. En la segunda, se explora la visión heterodoxa del estudio de la naturaleza a partir de la economía: la economía ecológica.

En este trabajo se estudia el impacto que tiene la migración y el envío de remesas en el combate de la pobreza y en el manejo de maíz entre productores de Tlaxcala. Los datos usados en la investigación se acopiaron mediante una encuesta aplicada a 1,884 maiceros distribuidos en los 60 municipios de la entidad, clasificados como de nivel de gasto bajo medio y alto. Los resultados muestran que los maiceros se encuentran en pobreza alimentaria y que la migración es una opción para atenuar esta situación; que las remesas son esenciales para la reproducción social de los maiceros, al cubrir una quinta parte del gasto mensual familiar; y que la migración ocasiona la ruptura tecnológica del manejo del maíz, promoviendo el uso inadecuado de agroquímicos y la disminución del empleo de tecnologías campesinas, que resultaron ser más eficientes que las tecnologías modernas.

Authors:   Universidad de Guadalajara, Okabe Taku
Published: June 2023

En cualquier estructura empresarial, las pymes son de mucha importancia. No obstante, las pymes enfrentan varias dificultades propias, en particular la carencia de financiamiento. Este problema proviene de la falta de credibilidad o confiabilidad de este sector, razón por la cual algunos gobiernos han adoptado diversas políticas y medidas para fortalecerlo. En este artículo, tomando como ejemplo el sistema de garantía del financiamiento para las pymes de Japón, se realizará un análisis comparativo con el de México. Mediante lo anterior se pretende discernir la situación actual del sistema en cuestión en ambos países, lo cual servirá para el mayor entendimiento mutuo entre México y Japón.
Pueblos de indios, hacendados y conflicto agrario en la Sierra de Tapalpa durante la época colonial
Authors:   Secretaria de Educación Pública, Javier Castillo Alam
Published: June 2023

En el presente escrito se abordan algunos de los con!ictos agrarios que protago-nizaron los pueblos de indios y los hacendados de la Sierra de Tapalpa entre los siglos XVI y XIX, cuando esta región se encontraba bajo el gobierno español. El análisis parte de una perspectiva que a"rma que el con!icto forma parte inma-nente de la realidad y del cambio social, y que el choque entre los pueblos de indios y hacendados no representa una llana controversia utilitarista, sino que por el contrario, cada uno de estos contendientes, en su lucha por el control de la propiedad agraria, buscaba reproducir un particular orden económico y social. Por medio de la exposición de algunos casos, en el presente artículo se dan cuenta de los mecanismos de acaparamiento, titulación y resistencia a la invasión de terrenos de los que las partes en pugna se sirvieron, aprovechando las disposiciones legales del Estado colonial

The experiment made it possible to develop new approaches to technological methods for increasing the yield of spring and winter durum wheat varieties against the background of creating prerequisites for preserving the natural fertility of the soil. Along with the released varieties, promising varieties of wheat were studied against the background of the use of new generation biofertilizers and developed doses of mineral nutrition for the planned yield levels. As, along with durum wheat varieties, which are accepted for zoning in the 8th region, modern varieties with high plasticity and adaptability to arid conditions were chosen. In addition, they are able to have a beneficial effect on the course of microbiological soil processes. The positive effect of the durum wheat root system with the symbiosis of biofertilizers was noted. The experiment was carried out in 2018…2022. for land use of the peasant farm "Eliseev A.N", which is located in the black soil zone of the southern Mikhailovsky district of the Volgograd region. Studied varieties of hard spring wheat: Krasnokutka 13, Donskaya elegy and varieties of winter durum wheat: Agat Donskoy and Aksinit with the use of biofertilizers and mineral nutrition for given yield levels (according to the method of Dospekhov B.A., 2011). A five-year experiment has shown that biofertilizers (Blago +, Gumi 20) may well constitute an alternative to traditional mineral nutrition to obtain a given level of yield of hard spring and winter wheat varieties. The use of biofertilizers (as a less expensive means of purchasing them) will increase the yield up to 3.05 t/ha for the Donskaya elegia variety, and up to 3.84 t/ha for winter durum wheat Aksinit, using biofertilizer Gumi 20. Maximum yield level was obtained on the variant of the complex application of Gumi 20+N221P87K135 on the Aksinit variety, which amounted to 6.62 t/ha (with a planned yield of 6.00 t/ha). On varieties of spring durum wheat, the highest yield was obtained in variety Donskaya elegia (5.32 t/ha) on the variant of application of Gumi 20+N221P87K135.

Using allometric equations, one can theoretically determine the morphological constants of representatives of the bird class, identify significant differences in the dynamics of these indicators, and determine which parameters do not obey these relationships. The principle of allometry allows, on the one hand, identifying and justifying the general model of the structure and functioning of the animal organism as a whole, and on the other hand, it creates a basis for assessing the quantitative and qualitative deviations of individual bird species from this model. The aim of the study was to determine the weight indicators of the pancreas in Japanese quails in post-incubation ontogenesis and to develop, based on this allometric equation, which links the live body weight and the absolute weight of the pancreas into a single whole. The article discusses the results of experimental studies of the pancreas in Japanese quails, based on which a new original allometric equation is proposed that takes into account the age of the bird. Since knowledge of the morphological features of the digestive system of Japanese quails allows you to purposefully influence their growth and development, the data obtained are necessary for breeding and selecting quails in the right direction to maintain their health and increase productivity.

Winter wheat is the main grain crop for Dagestan. In the irrigated conditions of the republic, the elements of the cultivation technology of this crop have been studied in detail. But, however, the issues of studying the adaptive potential of new promising varieties of winter wheat and improving the technology of their cultivation in the conditions of Piedmont Dagestan have not been practically studied. Our research was aimed at solving this problem in terms of selecting more productive varieties of winter wheat, developing a tillage system that meets the requirements of this crop, and using growth preparations, which have not been previously studied in the area under consideration. In the first experiment, it was revealed that the highest productivity of the wheat variety was formed on the variant with plowing with additional loosening of the subsurface layer up to 0.4 m with SibIME rippers. The average yield of varieties in this case was 4.67 t/ha, the excess with the data of the first (plowing) and second (loosening) options was 6.6 and 25.2%. Under the conditions under consideration, the maximum grain yields were recorded in the Grom variety - an average of 4.38 t/ha. In the second experiment, it was found that, against the background of the applied growth regulators, the yield of varieties was significant, while the maximum average value for varieties was noted on plots with the Novosil regulator - 5.36 t/ha, the excess compared to the control was 25.2%, and compared with the variants with regulators Alfasim and Biosil - 4.5 and 14.5%, respectively. As in the first experiment, in this case, in the conditions of Piedmont Dagestan, the Grom variety provided the highest productivity - an average of 5.07 t/ha in the experiment, which is 8.8% higher than the data of the Tanya variety.

Authors: Chakyarkandiyil Nisha , Prakasha G. S
Published: June 2023

The research in cooperative learning (CL) is robust. Despite the empirical research benefits of CL, its implementation faces challenges in teacher education classrooms. Teacher educators resist using CL and stick to the frontal teaching method. All this may be due to the difficulties perceived by teacher educators in implementing CL. The researchers used a concurrent triangulation mixed method research design to explore the perceived challenges of cooperative learning implementation among teacher educators from India. The researchers administered a questionnaire and obtained 300 responses from teacher educators through a survey, followed by a semi-structured interview among eight survey participants. The research findings revealed that the average perceived challenges among teacher educators are 63% due to teacher challenges, learner challenges, curriculum syllabus, and administrative challenges. Female teacher educators perceived higher challenges than males. ANOVA results revealed a difference in challenges faced across the age group. These results demonstrate the need for future researchers to conduct a more in-depth examination of the challenges in implementing CL with more extensive samples in various educational settings in other world regions to develop effective solutions.

Novel potential therapeutics to modify iron metabolism and red cell synthesis in diseases associated with defective erythropoiesis
Authors: Guerra Amaliris , Parhiz Hamideh , Rivella Stefano
Published: June 2023

Under normal conditions, iron metabolism is carefully regulated to sustain normal cellular functions and the production of hemoglobin in erythroid cells. Perturbation to the erythropoiesis-iron metabolism axis can result in iron imbalances and cause anemia or organ toxicity. Various congenital and acquired diseases associated with abnormal red cell production are characterized by aberrant iron absorption. Several recent studies have shown that improvements in red blood cell production also ameliorate iron metabolism and vice versa. Many therapeutics are now under development with the potential to improve a variety of hematologic diseases, from β-thalassemia and iron-refractory iron deficiency anemia to anemia of inflammation and polycythemia vera. This review summarizes selected mechanisms related to red cell production and iron metabolism and describes potential therapeutics and their current uses. We also consider the potential application of the discussed therapeutics on various diseases, alone or in combination. The vast repertoire of drugs under development offers new opportunities to improve the clinical care of patients suffering from congenital or acquired red blood cell disorders with limited or no treatment options.

RESUME. A comparative analysis of domestic and international research methodology and assessment in relation to the impact of plant protection products (PPP) on agricultural workers and the population shows that the existing methodological approaches in Ukraine need improvement. This concerns the principles of organization, definition of the research purpose and objectives, conducting measurements, ensuring the reliability of the results and substantiating the impact assessment criteria. The areas of improvement should correspond to the domestic theoretical foundations of hygienic regulation and modern approaches to the study and assessment of PPP in the EU. Aim. To substantiate the approaches to creating a methodology for studying and assessing the impact of PPP on operators, workers, outsiders and residents, harmonized with international requirements. Materials and Methods. A scientific analysis of legal acts regulating the field of registration of PPP, regulatory and methodical documents in force in Ukraine and the EU, regulating the organization of research, measurement, assessment and management of the impact of PPP on agricultural workers and the population during and after the use of these means was carried out. The directions for improving the methodology are outlined and research tasks are formulated to create a system of definitions, rules, principles and operations that meet the common goals and tasks of studying, assessing and managing the risk of exposure to hazardous substances on operators, workers, outsiders and residents in Ukraine and the EU. Results. The proposed methodology defines: the purpose and tasks of the research; the concept of influence; evaluation criterion – the maximum permissible level of exposure by inhalation and dermal route (mg active substance (AS)/kg body weight/day) and values derived from it – the controlled concentration in the air of the breathing zone and the working area (mg AS/m3), the controlled concentration in air of populated places (mg AS/m3); people who are subject to protection for a certain duration of exposure; task, object and subject of research; requirements for analytical methods of monitoring safety limits for inhalation and dermal exposure; peculiarities of planning field studies for the purpose of PPP registration and supervision after registration. Conclusions. The use of the proposed system of definitions, rules, principles and criteria can ensure compliance of studies with international requirements for the study and assessment of the PPP impact on operators, workers, outsiders and residents.

Published: June 2023

RESUME. Despite the fact that opioids do not have direct nephrotoxicity, a significant overdose, or their combination with alcohol and other psychotropic substances, contributes to the development of critical changes in many organs and systems of the body, which leads, in particular, to acute kidney injury (AKI). Aim. Using comparative analysis and the Kaplan-Meier method, to investigate the survival rates of patients with opioid drug poisoning complicated by acute respiratory distress syndrome treated with hemodialysis. Materials and Methods. A cohort retrospective analysis of the medical data of 128 patients (107 men, 21 women) aged 18 to 39 years who received treatment in the intensive care and extracorporeal detoxification department of the "Kyiv City Emergency Hospital" in the period 2017–2021 with a diagnosis of "Acute drug poisoning" (МКХ-10:Т40.0-Т40.3), complicated by the development of acute renal failure. Statistical analysis of the study results was performed using the Kaplan-Meier survival estimate; p≤0.05; the statistical analysis application package from Microsoft Excel 2019 was used. Results. Kaplan-Meier graphs indicated that patients with AKI due to morphine, heroin, and methadone poisoning have a statistically significant difference in survival rates (p < 0.05). The highest survival rates were shown by patients with morphine poisoning (100 %), the lowest were in groups with methadone (82.7 %) and heroin poisoning (48.3 %). Kaplan-Meier curves showed that all deaths occurred within 3–18 days of starting treatment, with most deaths (90 %) occurring within 3–12 days. Cumulative survival rates among patients with methadone-induced AKI stratified by blood alcohol content showed that among patients with methadone poisoning where alcohol was not detected, the survival rate was 100 %, and among patients with combined methadone and alcohol poisoning it was 75.2 %. Conclusions. Despite the similarity of the clinical picture in poisoning with natural and synthetic opioids (opioid syndrome), the causes of development of AKI and its course differ in patients with poisoning by different groups of drugs. Survival rates among patients with methadone poisoning are adversely affected by the presence of alcohol in the blood. Key Words: combined drug poisoning, renal failure.

An ethnobotanical investigation was carried out in Gafargaon sub-district (upazila) under Mymensingh district, Bangladesh that unveiled a total of 79 medicinal plant species under 74 genera and 46 families which were used to treat various ailments through 106 formularies. In addition, molecular docking and dynamics simulation studies were performed based on ethnobotanical outcome for the first time in Bangladesh to unveil potential drug candidates. The study revealed that most of the species used for primary healthcare were herbs (44.3%) followed by trees (36.7%), shrubs (10.2%) and climbers (8.8%). Leaves were found to be the most frequently used part (34%) compared to other plant parts. Factor of informant consensus values ranged from 0.975 to 0.984 and the highest value was recorded for respiratory tract disorders (0.984). Maximum number of taxa was unraveled to treat digestive and gastrointestinal disorders. Fidelity level varied from 41.2 to 100%, where 11 species showed 100% fidelity, and the citation frequency was found above 70% for 15 different ailments. Molecular docking study exposed 60% Stephania japonica phytocompounds scoring higher than the control drug Ibuprofen (-7.0 kcal/mol) targeting rheumatoid arthritis. The phytocompounds Oxostephanine, Trilobine and Epistephanine were identified as lead drug candidates with binding affinity of -9.7, -8.7 and -8.6 kcal/mol, respectively. Molecular interactions of these compounds were found significant to identify potential drug surface hotspots. Molecular dynamics simulation shed light on regional flexibility profiles and unraveled notable structural stability of the top three phytocompounds. The present study would offer foundational data for identifying potential bioactive compounds that could be utilized in novel drug discovery efforts.

The antibiotic susceptibility test revealed that the highest susceptibility was to Azithromycin, Gentamycin, and Ciprofloxacin, while the lowest susceptibility was to Amoxicillin/clavulanic acid, Tetracycline, and Trimethoprim/sulfamethoxazole. Interestingly, 36.84% of E. coli isolates showed multidrug resistance, which is a serious health concern as they may transmit and develop antibiotic resistance in the human body. The study highlights the need for continued surveillance and monitoring of dairy products for food safety and public health purposes.

Published: June 2023

Magnesium oxide has long been intriguing due to several significant phenomena, including wide laser emission, spin electron reflectivity, and defect-induced magnetism. MgO nanostructures have a variety of applications, from spintronics to wastewater treatment, depending on their size and shape. Mg is sensitive material for hydrogen and forms MgH2, so we used Mg/MgO as a sensor to sense hydrogen gas in the present work. Magnesium oxide thin films were synthesized by electrodeposition technique using magnesium nitrate salt. XRD results suggested that the deposited thin films have a face-centered cubic structure. X-ray photoelectron spectroscopy was used to detect the elemental composition and chemical state with the general electronic structure of the sample. The morphology and growth of deposited nanostructure with elemental mapping of the thin film were investigated by SEM-EDS. The UV-visible analysis shows the calculated band gap for MgO thin filmwas 4.16 eV which is in the ultraviolet region. The I-V characteristics have been studied to find out the effect of hydrogenation on the synthesized MgO nanostructure and the sensitivity responseof about 31%. It is quiteevident that MgO nanostructure may be used for gas sensing applications (such as H2 gas).

Published: June 2023

This paper describes the results of a beneficiation study conducted on low-grade fluorite ore. The study was aimed at the development of a suitable beneficiation process to produce chemical grade fluorite concentrate. The representative sample of the ore was up-graded by leaching and flotation process. The important parameters of froth flotation process were optimized to obtain highest grade and recovery of fluorite concentrate. A single-factor variation method was applied to get the optimum conditions of the process. The rougher concentrate was reground to liberate fine locked fluorite particles and two cleaning flotation were employed in close circuit to achieve higher grade concentrate. A process flowsheet was designed in the light of these tests. After optimization of process parameters, the fluorite ore containing 62.24% CaF2 could be upgraded to a concentrate assaying 97.55% CaF2 with an overall recovery of 92.73%. The prepared fluorite concentrate meets the specifications of chemical grade and is suitable for production of fluoride based chemicals.

In vitro Regeneration of an Endangered Medicinal Orchid Dendrobium crepidatum Lindl. & Paxton through Protocorm like bodies.
Authors: Pyati Ashok N
Published: June 2023

A protocol for regeneration of an endangered medicinal orchid Dendrobium crepidatum was established mainly via indirect protocorm like body (PLBs) formation. The PLBs procured from in vitro growth cultures was assessed in ½ MS medium alone and in combinations with 6-Benzyl amino purine (BAP), Kinetin (Kn) and α-Naphthalene acetic acid (NAA). The calli were induced from longitudinally bisected segments of PLBs. The optimum percentage of callus was obtained in ½ MS medium supplemented with BAP (1.0 mg/l) and combination of BAP (1.0 mg/l) with NAA (0.5 mg/l), where 64.3% and 83.3% of callus was formed respectively. PLB formation was achieved when callus was transferred onto the respective combinations in ½ MS basal medium. The optimum percentage (91.6%) of PLBs were regenerated in the combination of BAP with NAA. These PLBs differentiated into intact plantlets about 3 cm in height and with 4-5 roots were transplanted into potting mixture with highest rate of 93.3% survival rate in a green house.

Tutkimus paneutuu käsityönopettajien moniulotteiseen osaamiseen ja pedagogiseen toimintaan koronapandemian aikaansaamassa tilanteessa, jossa monenlaisia fyysisiä ja materiaalisia resursseja edellyttävä käsityönopetus jouduttiin siirtämään digitaaliseksi etäopetukseksi. Tutkimuksen aineiston muodostavat kahdessa webinaarissa syksyllä 2020 laaditut tekstidokumentit, joihin eri koulutusasteilla käsityötä opettavat sekä käsityönopettajaopiskelijat (n=123) kirjasivat ryhmätyöskentelyn perusteella kokemuksiaan, ajatuksiaan ja visioitaan käsityön etäopetuksesta. Aineistoa analysoitiin suhteessa opettajan moniulotteisen osaamisen malliin (MAP). Aineistossa etäopetukseen siirtyminen haastoi käsityönopettajien pedagogista sisältötietoa, mutta heidän vahva opetuksen ja oppimisen tietoperustansa sekä resilienssinsä auttoivat uudenlaisten pedagogisten ratkaisujen kehittämisessä. Sosiaalisiin taitoihin kuuluvia vuorovaikutustaitoja edellytettiin tiivistyneessä yhteydenpidossa käsityön etäopetuksen oppimisympäristönä toimiviin koteihin. Toimivan vuorovaikutuksen luominen digitaalisessa oppimisympäristössä nousi erityiseksi pedagogiseksi haasteeksi. Opettajien moninaisuutta koskevaan osaamiseen kuului ymmärrys oppijoiden erilaisista lähtökohdista ja resursseista. Opettajien ammatillista identiteettiä ja hyvinvointia heikensivät etäopetuksen kuormitus sekä käsityöoppiaineen sivuuttaminen koulujen etäopetuksen kehittämistyössä. Heidän ammatilliset arvonsa koskien laadukasta opetussuunnitelman tavoitteiden mukaista opetusta olivat ristiriidassa käytännön toteutusmahdollisuuksien kanssa. Nostamme uutena tulokulmana hakkeroinnin käsitteen uusiin tilanteisiin reagoivassa käsityön pedagogiikassa.
Are human health and environmental health inextricably linked?
Authors: Mariani David
Published: June 2023

ONE HEALTH approach, coined by FAO, perfectly sums up a concept that is strongly emerging in the international scientific community.
The environment (especially greenery and trees) plays a decisive role in human health and in wellbeing. A change in the development model that takes these issues into account, starting with the design of greener and more sustainable cities, appears necessary and urgent, given that in 2050 approximately 70% of the world’s population will live in large cities.
JUSTIFICATION OF THE ROLE AND PLACE OF THE NATIONAL GUARD OF UKRAINE IN STABILITY OPERATIONS IN THE FIELD OF SECURITY
Authors:   The National academy of hte National Guard of Ukraine, Hodlevskyi S.
Published: June 2023

The study reveals the essence of stability operations in the field of security on the example of localization of a non-international armed conflict and justifies the role and place of the National Guard of Ukraine in such operations as opposed to other components of the security and defense forces. The author considers the status, purpose, role, place of various power structures and agencies that can provide capabilities to participate in stability operations in the field of security. A correct understanding of the role and place of the Guard in such operations will allow governing authorities at various levels to properly use the security capabilities of the National Guard of Ukraine, avoid duplicating functions and performing uncharacteristic tasks by defense forces. It is concluded that the use of the Guard in stability operations in the field of security should be consistent with its structure, authority, and purpose as a military formation with law enforcement functions, namely, to respond to large-scale crisis situations within the country that threaten the state security of Ukraine and require massive use of security forces. The National Guard of Ukraine should play a leading role in stability operations in the field of security in the context of a non-international armed conflict (state of emergency): it should form the basis of an interagency grouping of security forces and ensure command and control of such a grouping. Stability operations in the field of security related to the localization of a non-international armed conflict should be carried out under the legal regime of the state of emergency, and the Main Directorate of the National Guard of Ukraine should lead the military command in the state of emergency. If the security forces are unable to stabilize the situation, and the threat of internationalization of the conflict and/or an external military threat, martial law will need to be introduced (in this case those will be the stability operations in the field of defense). The results obtained in this study can be used in practice to plan the use of the National Guard of Ukraine in stability actions (operations) of the various kinds.
ANALYSIS OF THE CONTENT AND ESSENCE OF MASS DISTURBANCE AS AN OBJECT OF TERMINATION BY UNITS OF THE NATIONAL GUARD OF UKRAINE

Published: June 2023

The article analyzes the content and essence of mass riots as an object of suppression by units of the National Guard of Ukraine. The positions and opinions of scientists and researchers regarding mass riots as a social phenomenon, an illegal act and as an object of termination by the National Guard of Ukraine were studied. The author proves the position that, in the modern sense, mass riots are not only a social phenomenon, but first of all a criminally punishable act. At the same time, from the point of view of the need to stop them by the National Guard of Ukraine, this social manifestation is characterized by a system of other criteria, which in turn does not exclude the illegality and high public danger of the corresponding actions, which determines the need for immediate response by law enforcement agencies to these processes. It has been proven that the content and essence of the powers of the National Guard of Ukraine in general and the servicemen of individual units and units determine the normative possibility and objective obligations to stop mass riots on the territory of Ukraine, thus fragmenting the need to stop a mass riot as an act of illegal behavior and the need for further pre-trial investigation of such actions by other subjects of law enforcement agencies. The conclusion was reached that the essence of a mass riot consists in the organized commission of actions directed against public order and morality, accompanied by violence, pogroms, arson, destruction of property, seizure of buildings or structures, forcible eviction of citizens, resistance to representatives of the authorities with the use of weapons. The prospect of further scientific research is the need for a more detailed study of the powers of the National Guard of Ukraine to stop mass riots under the conditions of the legal regime of martial law in Ukraine.
