SOURCES OF WATER POLLUTION AND NANOTECHNOLOGY-BASED WATER PURIFICATION TECHNIQUES
Authors: Rufat Shahbazov Rufat Shahbazov

Despite the measures taken in recent years, one of the main reasons for the disruption of the ecological balance of our region is its proximity to countries with somewhat more strained ecosystems.
In recent years, the rapid rise of groundwater in Baku city towards the surface should be considered a constant threat to metro stations and their tunnels. Previously, tunnels of the "Academy of Sciences," "Neftchilar," and "Koroglu" metro stations were flooded, and due to long-term oil leakage from the main oil pipelines, both oil and water entered the tunnels. A similar incident occurred in the oil pipelines passing near the Jeyranbatan reservoir. These kinds of events are always under control. Considering that the human body is made up of 80% water, we can imagine how harmful poor-quality water can be to health. Low-quality water not only harms humans but also damages the technical devices they use, such as kettles, dishwashers, and washing machines. It also causes clogging in water pipes. The only way to improve efficiency is to use the achievements of nanotechnology. One of the most promising directions in nanotechnology is associated with carbon nanotubes. Carbon nanotubes are structures made only of carbon atoms. Carbon nanotubes can be imagined as the tubular shape of a single molecular layer of graphite (graphene). Using the properties of nanotubes, they can be applied in water purification. With nanotubes, it is possible to produce drinking water from clouds in areas without water, and even turn seawater into drinkable water.

Authors: Рожков С. М. , Павленко В. І.
Published: December 2024

У статті розглянуто оптимізацію інфраструктури баз даних шляхом упровадження ефемерних реплік на інстансах AWS i3, що дало змогу підвищити продуктивність та економічну ефективність систем, що працюють із великими обсягами даних. У сучасних умовах бізнесу, який усе більше покладається на аналітичну обробку в режимі реального часу, зниження витрат та підвищення продуктивності інфраструктури стають ключовими завданнями. Інстанси AWS i3, що використовують локальні NVMe SSD-диски, є ідеальним рішенням для високонавантажених баз даних, оскільки забезпечують високу продуктивність вводу-виводу та значно зменшують затримки під час запису даних. Автори пропонують архітектуру, що включає ефемерні репліки для обробки запитів лише для читання та аналітичних запитів. Також розглянуто впровадження додаткових резервних вузлів для підвищення надійності та відмовостійкості системи. Запропоновані зміни передбачають збереження Master DB без змін, додавання третього вузла бази даних з ефемерним сховищем для перенесення навантаження лише для читання, а також зменшення розміру резервного вузла DR до мінімального робочого рівня. На основі проведеного дослідження автори демонструють ефективність використання ефемерних реплік у середовищах із високим навантаженням. Використання інстансів i3 дає змогу знизити витрати на інфраструктуру до 30% порівняно зі стандартними схемами та до 75–80% порівняно з RDS (SaaS). Водночас підвищується продуктивність системи, що дає змогу ефективніше обслуговувати запити для читання. Висновки статті підкреслюють переваги ефемерних реплік у підвищенні продуктивності вводу-виводу, зниженні витрат на інфраструктуру, підвищенні надійності та відмовостійкості, а також у зменшенні навантаження на основний сервер. Автори рекомендують упровадження цього підходу для організацій, які працюють із великими обсягами даних і прагнуть досягти високої продуктивності та економічної ефективності своєї інфраструктури баз даних.
АДАПТАЦІЯ АУДІОСПЕКТРОГРАМНИХ ТРАНСФОРМЕРІВ ДЛЯ ВИЗНАЧЕННЯ ЧАСТОТИ ДИХАННЯ
Authors: Ткаченко Д. А. , Одрібець С. П.
Published: December 2024

Ця стаття досліджує застосування аудіоспектрограмних трансформерів (AST) для задачі визначення частоти дихання з аудіозаписів, що є критичним показником під час скринінгу на апное уві сні. Традиційні методи, такі як полісомнографія, що використовуються для діагностики апное уві сні, є ресурсоємними та не широко доступними, що робить автоматизоване визначення частоти дихання цінною альтернативою. Останні досягнення в галузі глибокого навчання, зокрема моделі на основі трансформерів, пропонують перспективні рішення. Це дослідження адаптує попередньо навчену модель AST, первісно розроблену для задач класифікації аудіо, для визначення частоти дихання шляхом додавання механізмів уваги та регресійного шару. Ми донавчаємо модель AST на наборі даних ICBHI 2017 challenge, застосовуючи передавальне навчання для використання стійких представлень ознак, отриманих із великих наборів аудіоданих, таких як AudioSet. Наша методологія включає передискретизацію аудіофайлів, застосування смугових фільтрів та перетворення аудіосигналів у мел-спектрограми. Щоб вирішити проблему обмеженого розміру набору даних ICBHI, ми використовуємо методи нарощення даних, такі як SpecAugment, які вносять варіації у спектрограми для покращення узагальнюваності моделі. Ми пропонуємо два підходи до агрегації: агрегування з механізмом уваги та згорткове агрегування – для ефективного врахування часових залежностей у дихальних звуках. Експериментальні результати демонструють, що наша модель зі згортковим агрегуванням досягає середньої абсолютної похибки (MAE) 0,8320 та середньої відносної похибки (MRE) 12,56% на наборі даних ICBHI, перевершуючи попередню модель на 16,8% за MAE. Ці результати підкреслюють ефективність моделей на основі трансформерів в обробці складних аудіопатернів і висвітлюють потенціал моделей AST для ширшого застосування в аналізі дихальних звуків. Наше дослідження робить внесок у галузь машинного навчання, пропонуючи ефективний метод визначення частоти дихання з використанням моделей на основі трансформерів. Подальші дослідження будуть спрямовані на вдосконалення архітектури моделі та інтеграцію додаткових фізіологічних сигналів для підвищення точності.
Paulo Freire y la teoría de la objetivación: relaciones e implicaciones
Authors: Radford Luis
Published: December 2024

Paulo Freire propuso una nueva concepción de la educación. Una de sus características principales es concebirla como una práctica emancipadora. Esta concepción ha sido fuente de inspiración en recientes desarrollos de la teoría de la objetivación (TO), por ejemplo, en conceptos como la subjetividad, la alienación y la ética comunitaria. El objetivo de este artículo es explorar las relaciones e implicaciones entre la perspectiva educativa propuesta por Freire y la teoría de la objetivación. En la primera parte, presentaré una lectura de Freire desde la TO, en la que Freire aparece como un pensador hegeliano. En la segunda parte, discuto las relaciones y resonancias entre las ideas de Freire y la TO, sugiriendo que estas relaciones y resonancias están ancladas en una misma visión del mundo y de los individuos: una visión dialéctico-materialista. En la tercera parte, menciono algunas implicaciones que puede tener la obra de Freire tanto en desarrollos futuros como en la práctica de la teoría de la objetivación.

INTRODUCTION: The hematology laboratory at Hospital Universiti Sains Malaysia implements sample acceptance and rejection according to the rejection criteria following guidelines by ISO 15189. This study aims to evaluate causes and types of samples rejection and we also introduce an initiatives to reduce sample rejection. MATERIALS AND METHODS: A 2-month retrospective study was conducted by obtaining and evaluating data from samples sent to the hematology laboratory from June and July 2022. RESULTS: The laboratory received a total of 32,726 samples, out of which 1,084 (3.31%) were rejected. Rejection rates were 3.19% and 3.43% consecutively for June and July 2022. The leading cause of sample rejection was clotted samples (36.6%), followed by duplicate requests (22.9%), and insufficient amounts (16.9%). High sample rejection rates were recorded from the pediatric surgical ward, medical high-dependency unit, and otorhinolaryngology ward. The lowest rejection rate was from the outpatient clinic. CONCLUSIONS: The overall sample rejection rate was 3%. Therefore, a few mitigation strategies need to be employed to improve the acceptance rate.

Periodontal disease is a polymicrobial disease which initiation is by the presence and propagation of bacterial infections in dental biofilm. Gram-negative anaerobic bacteria were reported as the most prevalent oral bacteria associated with periodontitis. The periodontopathogens may destruct the periodontal tissue of the host directly or indirectly via inflammatory reaction. Porphyromonas gingivalis, Aggregatibacter actinomycetemcomitans, Fusobacterium nucleatum, Tanerella forsythia, Prevotella intermedia, Treponema denticola and Campylobacter rectus are Gram-negative anaerobic bacteria which are highly associated with periodontitis. This group of pathogens plays a vital role in the onset and subsequent development of periodontal disease. This review article highlights the general overview of Gram-negative anaerobic pathogens associated with periodontitis.

Integrating a SALC Into a Short-Term Study Abroad Program: Analyzing One Former Student’s Experience
Authors: Birdsell Brian J , Niioka Saki
Published: December 2024

Over the past 20 years, many universities in Japan have established self-access learning centers (SALCs) on their campuses. Proponents highlight the benefits SALCs offer to learners such as spaces for conversation practice, fostering friendships, supporting both guided and autonomous learning, and facilitating cross-cultural interactions. However, SALCs often remain isolated within their institutions, prompting growing interest in how to better integrate them into the broader university environment. In this paper, we first describe how the SALC at Hirosaki University has been integrated into Hayabusa College (a short-term study abroad program). Then, using an autobiographical narrative based on the second author’s experiences as a former Hayabusa student and English learner, we analyze key stages of her learning process. Framed within the context of Self-Determination Theory, we examine how her basic psychological needs—autonomy, competence, relatedness, and a fourth candidate need, novelty—were met. The paper highlights the potential of autobiographical narratives to trace language learning progress and demonstrate the role of SALCs in this process, offering insights into the unique experiences of language learners.
Crossing Language Boundaries on Campus: Using a SALC as a Learning Space For Interactive Homework
Authors: Birdsell Brian J
Published: December 2024

This small-scale study investigates the experiences of students engaging with a Self-Access Learning Center (SALC) at a Japanese university. The study focuses on students’ interviews with international exchange students in the SALC and subsequent reflections on these experiences as part of an English course assignment. Thematic analysis of the reflections reveals four main themes: curiosity to broaden one’s mind, overcoming anxiety and low self-efficacy, positive affect from connecting with others in English, and motivation and perseverance to learn English. The findings highlight the complex interplay of emotions, motivation, and language-learning experiences in the reflections. Despite initial challenges and some negative emotions, many students reported positive outcomes, including increased interest in foreign cultures, improved language confidence, and enhanced motivation to continue learning English. The study underscores the importance of SALCs in facilitating meaningful language learning experiences outside the traditional classroom.

This summary article describes the development of a special lecture series called The English Lounge (EL) Forum in Hirosaki University’s SALC. First, I outline the topics covered by the lecturers who come from various faculties at the university as well as individuals from outside the university. The goal is to develop a hub at the SALC for interdisciplinary learning and the sharing of new research and ideas through a “push-pull” framework that provides students activities that “pull” them back to the SALC throughout the year. Then, using data collected from the EL forum, I report on the number of participants, the diversity of the lecturers, and participation feedback. Finally, I provide some reflections and discuss future possibilities for the EL Forum.

Light crimes have been regulated in a limited manner in Indonesia in the Criminal Code (KUHP). The category includes violations that carry a maximum penalty of imprisonment of three months or a fine. However, minor crimes related to wealth are experiencing problems, along with the implementation of restorative justice. Therefore, there are 2 problems in this article, namely: (1) What is the deliberation model at the Sector Police Headquarters in resolving minor crimes related to assets based on restorative justice?  (2) How do Sector Police members supervise the implementation of the parties' agreement to encourage the achievement of the goals of restorative justice?  This legal research method is empirical with a criminological juridical approach. Research results: (1) The deliberation model at the Sector Police Headquarters in resolving minor crimes related to wealth is based on restorative justice using a deliberation model between the perpetrator and the victim with the principle of kinship. (2) How members of the Sector Police carry out supervision over the implementation of the agreement between the parties in order to encourage the achievement of the goals of equitable restorative justice. Investigators carry out investigations and act as mediators in the context of monitoring and implementing agreements between the parties that encourage the achievement of restorative justice.

Feature Distribution and Word Order Variation in Arabic Clauses: A Minimalist Account
Authors: S. Ellafi Ali
Published: December 2024

Arabic subject-verb agreement is asymmetrical: in VSO order the verb agrees with the subject in person and gender (partial agreement), whereas in SVO order the verb exhibits number agreement as well (full agreement). This agreement asymmetry has received a lot of attention in the generative literature over the past three decades. In fact, more than twenty proposals have been put forward in a number of different theoretical frameworks. At the same time, there have been no attempts for a formal treatment of OVS word order constructions. With respect to agreement, the OVS verb exhibits both of the properties that exist in the other word order types (VSO and SVO): partial agreement with the post-verbal subject and full agreement with the pre-verbal DP. A more thorough consideration of the data reveals that pre-verbal DPs share a number of other rather interesting properties. Our empirical findings lead to the conclusion that pre-verbal DPs (i.e., the superficial subject and object of SVO and OVS, respectively) are actually topics. The real subject of SVO and, similarly, the object of OVS is in fact verbally bound pronominal clitics. Using a Merge, Move and Agree-based theory of phrase structure and feature checking; and a Multiple Spell-Out model of phasal derivation, we hope to demonstrate that the computational systems of Minimalist Syntax can provide an adequate treatment of seven constructions: VSO, SVO and OVS, as well as four related variants (Ɂinna-headed SVO and OVS, and pro-drop SVO and OVS).
Surgeons Opinions on Management of Normal Appendix during Laparoscopy for Right Iliac Fossa Pain
Authors: Tarhuni Ashref , Elmehdawi Haitham
Published: December 2024

Right iliac fossa (RIF) pain is a common presentation in surgical emergencies, often leading to the diagnosis of acute appendicitis. However, the management of a normal appendix encountered during laparoscopic exploration for RIF pain remains debated among surgeons, with implications for patient outcomes and healthcare resources. This study aimed to assess the opinions of surgeons regarding the management of a normal appendix during laparoscopic surgery for RIF pain of uncertain etiology. A cross-sectional survey was conducted among 150 surgeons in Benghazi, yielding a 65.33% response rate. The survey collected demographic data, management opinions, and factors influencing decision-making regarding the removal of a normal appendix during laparoscopic procedures. The results showed that of the 98 respondents, approximately 80% reported that they routinely remove a normal appendix during laparoscopic surgery, primarily to prevent future appendicitis and avoid patient confusion. While most surgeons explained the risks and benefits of this decision to their patients, opinions varied on whether the decision should be made collaboratively. Notably, only 2% reported complications related to the removal of a normal appendix. The findings indicate a significant lack of consensus among surgeons concerning the management of a normal appendix during laparoscopic procedures. While many opt for routine removal, a substantial minority advocate for a more selective approach. The variability in practices highlights the need for clear, evidence-based guidelines to standardize care and optimize patient outcomes. This study underscores the heterogeneity in the management of normal appendices during laparoscopic exploration for RIF pain. Further research is necessary to develop definitive recommendations that can guide surgeons in clinical practice.

Published: December 2024

In this paper, the physical characteristics and radiation attenuation parameters of five ternary (50-x) PbO-xBi2O3-50P2O5 glass samples with different compositions were examined. The physical properties investigated were glass density (ρ), molar volume (VM), molar volume of oxygen (VO), and oxygen packing density (OPD). An empirical formula was used to determine the glass density theoretically and compared with the experimental density obtained from the Archimedes method. The comparison yielded reasonable results but did not achieve the desired level of accuracy as expected. The findings revealed that both density and molar volume exhibited an increase with higher Bi2O3 content. However, the molar volume of oxygen (VO) and oxygen packing density (OPD) show inconsistent behavior, showing a slight increase in VO and a decrease in OPD. Furthermore, the essential radiation properties, including the coefficient of linear attenuation (LAC), coefficient of mass attenuation (MAC), half-value layer (HVL), and tenth-value layer (TVL), were determined through experimental and theoretical calculations using the NaI (Tl) detection system and the Phy-X/PSD program, respectively. The results indicated reasonable consistency between the two methods, with the Bi16Pb34P50 sample demonstrating superior radiological properties among the samples. Overall, the study illustrated that the addition of bismuth to phosphate and lead glass improved the glass samples' radiation and physical characteristics.
Evaluation of the Recycling Conditions Through Injection Molding Using Fuzzy Logic Approach
Authors: Elsheikhi Salah , Badi Abdelaziz
Published: December 2024

Recycling plastic products is still essential and crucial in every country around the globe due to its positive benefits on the environment and the economy. There are several mixing procedures for recycling, and it is crucial to understand how these mixtures affect the quality of products by standards and specifications. Consequently, it is helpful to apply analysis and prediction techniques to find out scientifically. Artificial intelligence "AI" techniques are widely used in many manufacturing engineering fields such as recycling operations. This is because of the many advantages that artificial intelligence techniques offer, including the ability to reduce human errors, save time, provide digital support, and make objective decisions. This study intends to employ the fuzzy logic method as one of the "AI" techniques for predicting a significant property that customers frequently need based on their quality levels and standards. This study employed the injection molding process to forecast the values of a mechanical characteristic, specifically tensile strength, under specific operating conditions based on data from the authors' earlier work. This investigation was conducted using two distinct mixing plans. The first mixed all the raw materials, while the second mixed 50% of the raw materials with 50% of the recycled materials. The fuzzy logic results were acquired, and the mean absolute percentage error for the two plans was calculated. Additionally, the outcomes of the current study, which employed the fuzzy logic approach, were contrasted with those of the earlier study, which utilized the response surface methodology approach.  Furthermore, the results showed that the response surface technique approach is more accurate than the fuzzy logic since it has the lowest mean absolute percentage error.

Published: December 2024

Pesticides in Libya have increased recently in the agriculture sector to control pests, consequently improving field and horticultural crop productivity. The present study was undertaken to assess the current pesticide utilization among farmers in different farms across Beir Bullerjam's area. Data were collected from farmers using a structured questionnaire containing the following (socio-demographic details, awareness and knowledge, and farmer practices). Our results show that all farmers were male (100%), their farming experience was 13 years, and their average age was 46 years old. Not surprisingly, farmers did not know the modes or the compositions of pesticides being used and relied mainly on pesticide commercial retailers' knowledge. The most commonly used pesticides were: insecticides, herbicides, acaricides, and fungicides (47%), (34%), (18%), and (2%) respectively. Moreover, their trade names were: Oscar wp® 50, Roundup, Gramoxyone (herbicides), AQ Dorsban*4, Permethrin, Cyberkill 25, Mospy-one 20% sp, Fl-oil, Voliam Targo (insecticides), Vertimec (acaricide), and Strike (fungicide), and they were regularly utilized by farmers in this survey. We found that farmers reuse the same pesticides over years which may result in pesticide resistance of the targeted pest. Additionally, heavy use of insecticides by farmers could harm bee populations negatively in the region or decrease the natural enemies of pests. Farmer's awareness and attitudes towards pesticide use must be improved through agriculture extension agents or workshops for better food, healthy people, and ecosystems.
Effect of Polymer Flooding on Oil Recovery Using Reservoir Simulation, Umm-Faroud Field, Sirt Basin, Libya
Authors: Eljareh Salem , Mahdi Hameeda , A. Gwazi Asmaa
Published: December 2024

This work uses Polymer flooding as an Enhanced Oil Recovery (EOR) technique to increase the injected water viscosity to reduce the mobility ratio and improve sweep efficiency. A reservoir model was constructed using the reservoir-simulating method with Computer Modeling Group software (CMGs IMEX) to predict the oil production and water cut from Umm Foroud field, Sirt Basin, Libya. The models are based on data collected from 17 wells from the Umm Foroud field. Off which, five wells were utilized to build the models, while the other 12 wells were used to validate them. Three scenarios were made; the first was used to predict oil recovery with water injection only, with no polymer, the second model to predict oil recovery with polymer flooding of 10% concentration, and the third with polymer flooding of 20% concentration. The viscosity of water increased by two different concentrations of polymers. Results showed that when water viscosity increased, a significant reduction in mobility ratio occurred and hence, the sweep efficiency was improved. Oil production was improved (increased) in the second and third scenarios where the polymer-flooding scenario (10% and 20% polymer solution concentration) was used. However, the water cut was reduced when compared to water injection.

Shibhonia buxanthi, a new genus and species of dorsally punctate Mirini from the island of Socotra (Hemiptera: Heteroptera: Miridae)
Authors: Carapezza Attilio , Kment Petr
Published: December 2024

Shibhonia buxanthi gen. & sp. nov., living on Buxus hildebrandtii (senior synonym of Buxanthus pedicellatus) (Buxales: Buxaceae) on Socotra Island (Yemen) is described and illustrated. The new taxon is the sixth species of Miridae recorded from the island and the first endemic genus of this family. Due to the complex of its characters, it belongs to the group of dorsally punctate genera of the tribe Mirini. Inside this group it shows some superficial similarities (especially the colouration and body shape) with the genera Capsus Fabricius, 1803, Chilocrates Horváth, 1889 and Koreocoris Cho & Kwon, 2008, but it is readily distinguished from both by relevant morphological differences, particularly in the structure of male and female genitalia.

The article explores the possibility of using the Ansys software package to model slabs designed
as beams manufactured using a 3D printer. To evaluate the effectiveness of this model, a numerical
experiment was conducted, during which the beam structure was subjected to a destructive load. The
simulation results were compared with the results of a physical experiment to verify the accuracy of the model. The input data for the calculation were based on parameters similar to those of an experiment conducted by Diego Veloso at the University of São Paulo, where a truss beam was studied.
The model was built using both solid and beam elements, with loads applied to the nodes of the model
as distributed forces over the area, replicating the conditions of the full-scale experiment.
The calculation results revealed that the failure of the beam begins when the load on the nodes reaches 500 kg. In a full-scale experiment, the destruction occurred when a load of 700 kg was reached.These data coincide with the results of the full-scale experiment, confirming the accuracy of the chosen modeling method. Thus, the proposed calculation method can be successfully applied to the design of load-bearing elements of buildings constructed using layer-by-layer 3D printing with construction printers.

Published: December 2024

This paper deals with the differences between regular and singular points of equilibrium states of
elastic systems. The author provides a classification of singular points based on mathematical, mechanical and geometrical approaches. Aspects concerning nondegenerate (regular) critical points in which the first differential is zero and the second differential (quadratic form) is not degenerate are disclosed. The conditions of stability and instability of isolated equilibria are discussed, as well as the influence of the primary nonzero terms of the potential energy expansion on the stability of degenerate equilibria. The conditions for bifurcation loss of stability in the context of incomplete equilibrium of elastic systems are considered. It is analyzed that a necessary condition for the appearance of bifurcation points is the presence of an energetically orthogonal complement. The influence of initial geometrical imperfections on the character of stability loss is also considered.

Background: Diagnoses of Eustachian tube dysfunction in Benin City are typically made clinically or with tympanometry. The Eustachian Tube Dysfunction Questionnaire-7 (ETDQ-7) is a scoring system with potential as an alternative tool, particularly useful in resource-challenged settings. This novel tool may not have been previously investigated in this environment for its accuracy.
Objective: The study aimed to compare the diagnostic accuracy of the Eustachian Tube Dysfunction Questionnaire-7 (ETDQ-7) to tympanometry (used as the reference standard) in identifying adult patients with Eustachian tube dysfunction at the ENT clinic of the University of Benin Teaching Hospital.
Methodology: This was a hospital-based, prospective diagnostic accuracy study using a case-control design. A total of 150 study participants were recruited, including 75 case participants and 75 controls. The ETDQ-7 instrument was administered to all participants, followed by tympanometry for each. Data were analyzed using the IBM Statistical Package for the Social Sciences (IBM SPSS) version 26.
Results: The diagnostic accuracy of the ETDQ-7 in the study group was found to be 68%, while in the control group, it was 85.4%. The Area Under the Curve (AUC) for the study group was approximately 0.75, and for the control group, it was approximately 0.80.
Conclusion: The ETDQ-7 demonstrates moderate accuracy for the diagnosis of Eustachian tube dysfunction, making it a useful tool for adoption as a screening method. Its ease of administration, noninvasive nature, and reproducibility make it particularly advantageous in settings where resources are limited. However, due to its moderate specificity, it is best utilized as a preliminary screening tool rather than a definitive diagnostic method.
The objective side of murder as a typical legal construction
Authors: Berezhnyi Serhiy
Published: December 2024

Protection of a person from criminal offenses, protection of his rights, freedoms and legitimate interests is one of the most important constitutional tasks of the State. The objective side of criminal offenses is an important part of the application of the law on criminal responsibility. The objective side of a criminal offense characterizes the external process of criminal behavior and contains information necessary for the correct qualification of the act. An essential role is played by the objective side in distinguishing adjacent components of criminal offenses. Especially when distinguishing acts that encroach on the same object and have the same form of guilt. Today's requirements require a clear understanding of the theory of the structural parts of a criminal offense, in particular, the objective side. The current stage of the development of domestic science of criminal law necessitates further research of scientific views on the theory of qualification of criminal offenses and their successful application by law enforcement agencies.

Key words: murder, the objective side of criminal offenses, qualification of criminal offenses on objective grounds, judicial practice.
