Published: November 2023

Воздействие различных эндогенных факторов на лесные фитоценозы способствует формированию пространственно-мозаичной структуры и является естественной и неизменной составляющей динамики лесных сообществ. Частичный распад полога древостоя и образования в нем окон способствуют формированию разновозрастных и полидоминантных лесных сообществ [1]. Чернопихтово-кедрово-широколиственные леса являются коренными и наиболее сложными по пространственной структуре лесами в Приморском крае и на всем Дальнем Востоке [2] Формирование небольших по площади естественных вывалов, состоящих из одного-двух деревьев, является одной из основных причин формирования сложной пространственной структуры кедрово-широколиственных сообществ. Окна, образующиеся на местах подобных вывалов, создают условия, необходимые для возобновления различных древесных видов. Изучение процесса возобновления этих видов позволит иметь более широкое представление о формировании сложных пространственных структур черхнопихтово-кедрово-широколиственных лесов. В связи с этим цель данной работы – исследовать первые стадии зарастания окон в чернопихтово-кедрово-широколиственных лесах на юге Приморского края. По результатам проделанной работы мы можем сделать следующие выводы: Все окна мелкомасштабные, по площади не превышают 185 м2. Окна образованы деревьями в количестве от 1 до 5. Среди валежа наблюдаются как сломанные деревья, так и деревья с образованием ветровально-почвенного комплекса (ВПК). Всего нами было обнаружено 2304 особей, относящихся к 28 видам в составе возобновления. В сравнении с древостоем не было отмечено: березы плосколистной, липы маньчжурской (Tilia mandshurica Rupr. & Maxim.) и тиса остроконечного (Tilia mandshurica Rupr. & Maxim.). Самыми многочисленными видами в составе возобновления являются 2 вида – сирень амурская и ясень маньчжурский (40 и 34% от всех особей соответственно). Среди остальных видов наиболее часто встречаются – клен моно, маакия амурская, клен бородчатый, дуб монгольский, липа амурская, граб сердцелистный. Среди хвойных встречены 3 вида – кедр корейский, пихта цельнолистная и пихта белокорая, их доля не превышает 3%. Для всех видов наблюдается сильное изреживание с увеличением высоты Основными лимитирующими факторами, влияющими на возобновление, оказались среди абиотических: положение относительно центра окна, которое влияет на освещенность и микрорельеф местности, определяющий количество свободного субстрата. Среди биотических: конкуренция подроста за субстрат и свет, затенение травянистыми растениями, кустарниками и лианами, а также повреждение подроста травоядными животными (скусывание). Корреляции между размерами окна и количеством видов или отдельных особей, найденных в нем не обнаружено. Работа поддержана грантом РНФ № 22-24-00098.

Published: November 2023

The article examines the issue of the general structure of the national security management of Ukraine. Various approaches of scientists to the issue of the system of ensuring national security and the normative consolidation of basic concepts in the field of security are analyzed. Attention is focused on its structural elements and compliance of the National Security and Defense Council of Ukraine with the features of the subject of the specified system. Also, with reference to the current legislation of Ukraine, the place of the Council in the system of state management bodies of the national security system of Ukraine is substantiated. Particular attention is paid to the constitutional appointment and its functions, the authority to make decisions on the application of personal restrictive measures (sanctions) and the grounds for such application. It was found that the powers of the Council regarding the selection of types of sanctions are not limited, as the law does not establish an exhaustive list of their types. Attention was drawn to the fact that the implemented decision of the Council on the application of sanctions gives rise to the emergence of special legal relations in the sphere of public administration by the national security system involving subjects of power and subjects of private law, within public-law disputes often arise. The legal status of state bodies and their place in the state administration system, similar to the National Security and Defense Council of Ukraine, was also studied on the example of foreign countries, namely the United States of America, the Republic of France, the Federal Republic of Germany and the Republic of Poland. The need to improve the legal status of the National Security and Defense Council of Ukraine in terms of its performance of tasks that arise in the process of the need to apply sanctions to the relevant legal entities has been proven. Ways to improve the activity are proposed, which will help to improve its functioning and reduce the number of public legal disputes, in particular, regarding the appeal of the applied sanctions.
THE FIRST TRAINING MANUAL ON HYDROGRAPHY AND WATER RESOURCES OF EUROPE PUBLISHED IN UKRAINE (2023)
Authors:   Lesya Ukrainka Volyn National University, Lutsk, Ukraine, Zabokrytska M.R.
Published: November 2023

The article presents and analyzes the training manual “Hydrography and Water Resources of Europe”, published by the professor Taras Shevchenko National University of Kyiv V.K. Khilchevskyi in 2023. The first training manual k published in Ukraine on this topic briefly outlines the basics of EU water policy, characterizes rivers, lakes and reservoirs on a regional basis (UN geoscheme – Northern, Western, Southern and Eastern Europe), as well as seas washing the shores of Europe. The problems of global water resources are considered, the ranking of European countries in terms of renewable water resources and the index of water resource exploitation is given. In the context of all directions, questions on Ukraine were considered. In Europe, hydrographic surveys are of great importance for water management. In particular, according to the European Union Water Framework Directive (WFD) adopted in 2000, the hydrographic zoning of countries’ territories is an important step for creating river basin management plans in the implementation of water policy. This approach is used by both EU member states and other European countries that have taken the provisions of the EU WFD as the basis for their activities. Water resources in a broad sense are all the waters of the hydrosphere, including the waters of the oceans and seas, rivers and lakes, groundwater, and glaciers. In practice, both in Europe and in many countries of the world, the concept of “water resources” is interpreted in a narrower sense – these are fresh surface and groundwater that are in water bodies and are used or can be used by humans. Water resources are managed according to the basin principle, but water resources are taken into account within individual countries. For. structuring the presentation of the material in this tutorial, the division of Europe into subregions according to the UN geoscheme was chosen, according to which 4 subregions are distinguished: Northern Europe; Western Europe; Southern Europe; Eastern Europe – a total of 44 countries whose capitals are located in this part of the world. But geopolitically, Europe includes 50 sovereign states. Their territory is within the framework of the general definition of Europe, they have membership in international European organizations. The content of the manual is structured into four parts: I – Physical-geographical and economic-geographical characteristics of Europe; II – EU Environmental and Water Policy; ІІІ – Hydrography; IV – Water resources. The training manual is intended for students enrolled in the educational program “Management and Ecology of Water Resources”, specialty 103 “Earth Sciences”. It can also be useful for students of other educational programs of specialties 103 “Earth Sciences” and 106 “Geography”, which study water resources.

Published: November 2023

The Indian summer monsoon (ISM) spans four months beginning from June to September (JJAS) and produced extensive rainfall over Indian continents. The land-sea heating contrast is one of the major factors facilitating ISM. ISM is managed with the aid of several monsoon semi-permanent features (MSF) which include Pakistan heat low, cross-equatorial low-level jet over the Arabian Sea, and the tropical easterly jet over the Indian Ocean at 200 hPa, Mascarene High, and seasonal anti-cyclone over the Tibet. Any fluctuations in these SMF can strongly modulate Indian Summer Monsoon Rainfall (ISMR). Therefore, it is imperative that the structure and variability of MSF need to be examined in changing climate scenarios to assess its impact on the future monsoon.  Further, ISM also experiences internal variability in terms of deficit and surplus years, therefore the impact of MSF on this variability also needs to be examined. The main objective of the study is to examine the variation of rainfall in JJAS over the Indian monsoon core region and the characteristics of SMF for two contrasting monsoon years. Based on the previous study observed that the monsoon core zone has an important role to play in the ISM so for the rainfall study take the monsoon core zone for the study purpose. The 5th generation European Centre for Medium-Range Weather Forecasts (ERA5), India Meteorological Department (IMD) rainfall datasets from 1981-2020, and Coupled Model Intercomparison Project Phase 6 (CMIP6) 2015-2021 for four different SSP scenarios. In addition, to determine the changes in these MSF and their impact on rainfall for ISM. For the calculation of rainfall percentage departure of IMD and ERA5 and CMIP6 dataset following Rajeevan et al. (2010).

Published: November 2023

A constant, clear trend is observed toward the appointment of forensic medical examinations in criminal and civil claims to healthcare institutions and individual medical workers. In some cases, criminal cases were initiated against medical workers without sufficient grounds. In their grief, relatives are not always able to objectively assess the actions of medical workers, which is often the reason for contacting investigative and judicial instances. Lawyers also support them in this. Often, medical workers receive complaints because they do not know how to properly explain to the patient and relatives the complexity of the situation and insist on hospitalization. All this is taken into service by lawyers, including medical professionals. Thanks to their actions, the prosecutor’s office, investigation, and courts are forced to do unnecessary and not always necessary work. All the above has become more often manifested during the investigation and trials to mitigate the guilt of the accused in criminal cases that harm health. The defendant or the representative of the defense declares that the consequences of the injury caused to the victim or the death of the victim are the result of the improper actions of medical workers, that is, the victim received inappropriate medical care. Explaining the purpose pursued by these people is difficult. However, such statements only lead to a delay in investigative actions and trials, appointment of additional, and sometimes repeated, forensic medical examinations, including commissions. In court hearings, not only forensic medical experts who conducted examinations are called witnesses to the incident but also medical workers. The presented work provides an expert observation of the death of a 4-year-old child. During the investigation and trial, the issue of inappropriate medical care arose, and a forensic medical examination commission was appointed. The forensic medical examination revealed that the child received appropriate medical care and had no connection with bodily harm.
About teeth in forensic medicine: 120 years since G.I. Vilga defended Russia’s first doctoral dissertation on forensic dentistry
Authors: Pashkov Konstantin A. , Barinov Evgeny Kh. , Bondar Vladimir A.
Published: November 2023

1923 marked the 120th anniversary of the defense of the doctoral dissertation “On Teeth in Forensic Medicine” by the outstanding Russian odontologist Gilyariy Ivanovich Vilga. The dissertation included an extensive review of foreign literature and the results of his research performed on 160 young healthy men (soldiers) using hand-made instruments.
The work, performed at the junction of odontology and forensic medicine, was the first in Russia to analyze traumatic dental injuries (dislocations and fractures) from this point of view, describe methods of identification of a person by odontological status, methods of studying bite wounds, and approaches to forensic examination of dental and dental technique errors. For many years, this work remained the only manual for odontologists and forensic experts in Russia.
Many provisions of the doctoral dissertation of G.I. Vilga “About teeth in forensic medical relation” have not lost their relevance even today; all this certainly allows us to consider G.I. Vilga as the founder of domestic forensic dentistry.

Low-frequency chatter severely limits robotic milling efficiency. In this paper, tuned mass dampers (TMDs) are introduced to suppress low-frequency chatter based on robotic modal directionality. A TMD model with mounting angle is established, and the suppression effect of TMD on the robotic low-frequency dynamic compliance with different mounting directions is analyzed together with experiments. Then, low-frequency chatter is further suppressed by suppressing side-frequency dynamic compliance. The milling experiments show that the TMD can significantly suppress low-frequency chatter and improve cutting amount, and a better effect can be achieved when TMDs act at both the low-frequency mode and side frequencies.

In this paper, different approaches to visualize CAM simulation results are presented. Simulated machined surfaces can be rendered in a photorealistic manner taking into account real tool motions and vibrations measured during the machining process. The actual tool trajectories are used to derive the microrelief of machined surface that lead to different reflective properties to be used in the CAM surface rendering pipeline. Broaching and grinding were two machining processes to adopt this photorealistic visualization. First, the generic CAM simulation computed the triangulated representation of the in-process workpiece. Second, the triangles were enriched with the computed micro topography information that is used by the developed shader implementation during the visualization process.

Published: November 2023

Manufacturing operations in large machine tools often requires several hours per part. Ensuring output quality is vital to avoid time and financial losses. While quality assurance was always problematic and costly, the recent advent of Industry 4.0 brought a new perspective to the problem as cutting machines are now fully digitized. This paper proposes a process control framework that combines a fingerprint approach that detects deviations with respect to the validated process and a Long Short-Term Memory (LSTM) algorithm that predicts the upcoming signals. This paper demonstrates how combining these two methodologies surpasses the performance of previous purely learning-based algorithms.

Published: November 2023

Drilling is a crucial process in industrial production and the quality of the machined hole has a decisive impact on the final part quality. However, there are various disturbances in the manufacturing process, which makes the non-value-adding quality inspection unavoidable. In this paper, high-frequently recorded internal NC-signal data and the vibration sensor data from the machine protection control unit (MPC) are used to predict hole quality for the drilling process. The analysis of the preprocessed data reveals a linear association between the hole quality characteristics and extracted features. For inline quality monitoring, interpretable models for the quality characteristics of straightness and roundness are developed. The proposed approach showcases the potential as an economical alternative to quality inspection by random sampling in mass production.

In this paper an efficient geometry description algorithm is proposed that reads the cutting-edge points of an arbitrary broaching tool from the provided model in a pixelated format which is surely available in any engineering environment. The created geometry can be scaled arbitrarily and used for simulations, ensuring adaptability due to its point cloud like format. High precision machining requires large resolution (microns) that often leads to unmanageable data storage needs with increased calculation time. To overcome these problems, the proposed algorithm is built around a pseudo arc-length-like continuation of the cutting-edge pixels, which works on broaching tools due to the cutting-edge geometry is free from any loops or isolas. This method provides all the important data including the high-resolution edge sections, related chip thicknesses and the normal directions for dynamic simulations and manufacturing.
Ultrastructural and immunofluorescence features of the epidermal cells and its secretory granules in the amphioxus Branchiostoma lanceolatum L.
Authors: Kević Nives , Restović Ivana , Bočina Ivana
Published: November 2023

Background and purpose: In the vertebrate family, the epidermis of terrestrial animals is keratinized while in aquatic forms and amphibians can produce mucus. Amphioxus, a cephalochordate, is an important animal model in the study of chordate phylogeny. Major cytoskeletal and extracellular matrix proteins in epidermal cells of amphioxus (Branchiostoma lanceolatum L.) were investigated using transmission electron microscopy and immunofluorescence.
Materials and methods: Amphioxus specimens were fresh caught in the Adriatic Sea. Tissue samples were fixed and prepared for transmission electron microscopy and immunofluorescence techniques.
Results: The epidermis consisted of one-layered columnar epithelium. Epithelial cells contained voluminous nucleus, a well-developed supranuclear Golgi apparatus, abundant vesicles and apical secretory vesicles surrounded by cytokeratin filaments. A single row of smaller vesicles also appeared close to the basal cell membrane. Strong positive immunolocalization of hyaluronic acid and collagen type I was observed in the apical domain of the plasma membrane of amphioxus, respectively. The positive signal of hyaluronan and collagen proteins referred to the secretory granules in the apical domain of the epidermal cell. Strong positive labelling of aggrecan was seen around the cell nucleus, deep below the apical domain, suggesting that aggrecan is not located in the secretory granules. A strong signal of the cytokeratin 10 protein was seen throughout the cytoplasm of the epidermal cells.
Conclusion: Due to its morphology and histochemical composition, epidermal cells of amphioxus may contribute to course surface protection and the mucous layer in amphioxus may serve as a physical barrier between the body and its environment.

Bakkâlî Nispetiyle Anılan Hanefî Fakihin Kimliğinin Tespiti ve Bazı Fıkhî Görüşleri
Authors: KOÇ Ekrem
Published: November 2023

Fıkıh ilmi ve mezheplerinin müktesebatının oluşturulmasında katkı sunan mezhep imamlarının usûlünü ve görüşlerini sonraki nesillere aktaran, onların öğrencileriyle irtibatlı çok sayıda âlim bulunmaktadır. Hanefî mezhebi tarihinde de eserleri, görüşleri veya sadece isimleri günümüze ulaşan birçok âlim bulunmaktadır. Eserleriyle ön plana çıkan âlimlerin görüşlerine yazdıkları eserlerinden ulaşılmaktadır. Eserleri olmayan veya eserleri günümüze ulaşmayan bazı âlimlerin görüşlerine ise fıkıh külliyatı içerisinde diğer âlimler tarafından yapılan nakillerle muttali olmaktayız. Ne yazık ki ne eseri ne de görüşü bize ulaşan yalnız ismine atıfta bulunulan nice âlim söz konusudur. Bu çalışmada, fıkıh literatüründe ismi geçmesine rağmen ilmî şahsiyeti, fıkıhtaki konumu ve eserleri günümüze ulaşmayan Hanefî fakih Bakkâlî (öl. 452/1060) konu edilmiştir. Makale, Bakkâlî'nin kim olduğunun tespiti konusunda çeşitli kaynakları ve delilleri incelemektedir. Zira Bakkâlî nispetiyle anılan iki farklı âlimin varlığı söz konusudur. Bu muammanın giderilmesi gerekmektedir. Makalenin temel argümanını, tabakât eserlerinden ziyade Hanefî fıkıh külliyatının muteber kaynakları arasında yer alan fıkıh kitapları üzerinde yapılan incelemeler ve dijital kaynaklardaki taramalar şekillendirmiş ve açığa kavuşturmuştur. Bakkâlî isimli âlimin ilmî şahsiyeti ile fıkhî görüşlerinin tespiti ve tanıtımı makalenin mümeyyiz vasfını oluşturmaktadır. Bakkâlî, Hanefî fıkıh geleneği içinde etkili bir fakih olarak kabul edilmiş ve meşâyihten sayılmıştır. Meşâyih olarak adlandırılan âlimler, mezhep içindeki içtihat çeşitliliğini düzenlemek ve yeni fıkhî meselelere çözüm üretmek amacıyla faaliyet gösterirler. Bununla birlikte mevcut deliller göz önünde bulundurularak Bakkâlî nispetiyle ön plana çıkan Bakkâlî’nin Hanefî mezhebindeki görüşlerine müracaat edilen Bakkâlî olmadığı ispat edilirken; ortaya çıkan ihtimaller içinden Bakkâlî’nin kimliğinin tespitinde ağır basan görüşlere yer verilmektedir. Bu nedenle Bakkâlî’nin daha fazla araştırma ve inceleme gerektiren bir figür olduğuna dikkat çekilmektedir. Bu makalenin Hanefî fıkıh geleneğinin anlaşılmasına katkı sağlayabileceği vurgulanmaktadır. Onun bazı ibadet ve muamelat konularındaki fıkhi görüşleri, önemli tartışmaları yansıtmaktadır. O, Hanefî mezhebinin temel prensiplerine bağlı kalmış olsa da zaman zaman imamların veya mezhebin genel görüşlerine karşı özgün içtihatlar geliştirmiştir. Onun özgün içtihatları ve fıkhî görüşleri, mezhep literatüründe önemli bir yer tutmaktadır. Özellikle fetva konularında etkili olmuş ve kendi görüşlerini sonraki fakihlere miras bırakmıştır. Bu tür bir tespit çalışması, ilim tarihi ve fıkıh tarihi alanlarında bir bilimsel sorunun çözümünü hedefler. İlgili kişilerin kimliklerinin ve uzmanlık alanlarının netleştirilmesi, tarihsel ve bilimsel bir açıklığın sağlanmasına yardımcı olabilir. Bu makale, bu konuda daha fazla bilgi edinmeyi ve belirsizlikleri azaltmayı amaçlayarak fıkıh tarihine katkıda bulunmayı hedeflemektedir.

Authors: Victor Ibiapina Cunha Morais José , Andrade Mariana Dionísio de
Published: November 2023

O Tribunal de Justiça do Ceará editou a Resolução nº 15/2021 afastando do juiz da extensão de prazo para a continuidade da investigação criminal em fase de inquérito policial. O estudo busca responder ao seguinte problema de pesquisa: As alterações provocadas pela Resolução nº 15/2021 do TJCE na tramitação de inquéritos policiais asseguram a imparcialidade judicial como é feito no juízo de garantias, a partir da perspectiva axiomática do garantismo penal de Luigi Ferrajoli. Para desenvolver o assunto, é necessário conceituar a imparcialidade judicial e seus desdobramentos para o inquérito policial; abordar a figura do juiz de garantias a partir da perspectiva da imparcialidade; e identificar os principais aspectos do inquérito policial contidos na legislação e doutrina que levaram às mudanças estabelecidas pela Resolução nº 15/2021 do TJCE A metodologia possui abordagem qualitativa, descritivo-analítica, com base em revisão de literatura, natureza pura, confrontando o teor da Resolução n. 15/2021 do TJCE e com a imparcialidade judicial prevista no juízo de garantias, a partir da perspectiva axiomática do garantismo penal de Luigi Ferrajoli. Conclui-se que as alterações trazidas pela Resolução nº 15/2021 asseguram a ideia da imparcialidade judicial a partir do respeito ao princípio do acusatório extraído da teoria garantista.
Do livre convencimento à possibilidade de decisões judiciais discricionárias: estudo de decisões no âmbito da execução penal no contexto da pandemia de Covid-19
Authors: Puziol Giuberti Glenio , Bonfigli Fiammetta
Published: November 2023

O estudo pretende demonstrar que a permissão do artigo 155 do Código de Processo Penal brasileiro, que trata do princípio do livre convencimento motivado, possibilita a prolação de decisões judiciais subjetivas. Para tanto, será utilizada como base teórica a Crítica Hermenêutica do Direito (CHD), que trabalha a decisão judicial em perspectiva não discricionária. Partindo da base teórica, será feita a análise de três decisões judiciais exaradas pelo Tribunal de Justiça do Estado de São Paulo durante a pandemia de COVID-19 e que ganharam repercussão na mídia por denegarem direitos fundamentais de custodiados no âmbito da execução penal, sob argumentação subjetiva.
