Sustainable Development in The Plastic Arts
No full textFine art has an important role in achieving sustainable development through the artistic product achieved by the plastic artist and that art has an important role in the development of man in culture and taste, which is a human product that began from the formulation of the artwork and then its impact on the individual in terms of education and psychological, art is the language of feelings and ideas affecting the recipient in terms of response, taste and instilling values in the souls The artist has used various artistic techniques since ancient times to this day, derived these techniques material from the environment and achieved wonderful technical achievements within the scope of sustainable development
Study the Characterization of Silver Nanoparticles Synthesized Using Natural Extracts Lantana Camara
No full textThe current research problem is encapsulated in the following inquiries: Do teachers possess professional competence from the viewpoint of their students in vocational schools? The aim of the current research was as follows: 1- To assess the professional competence of teachers from the perspective of students in vocational schools. 2- To evaluate the professional competence of teachers from the viewpoint of students based on gender (males/females). The research defines the objective boundaries as follows: including the variables of the current research on the level of professional competence from the perspective of students. The spatial boundaries encompass vocational schools in Al-Najaf Al-Ashraf province. The human boundaries focus on a sample of morning students in vocational schools in the Directorate General of Education in Al-Najaf Al-Ashraf province, including both genders (males and females). The temporal boundaries are set for the academic year (2023-2024). The theoretical framework included previous studies on the variable of professional competence, discussing theories and previous studies, and elucidating their utility. The researchers employed the descriptive correlational method, with the research population consisting of students in the vocational stage in government schools for the academic year (2023-2024), with a total population of 539 students. The primary research sample was selected randomly and proportionally, comprising 400 students. To achieve the research objectives, the researchers constructed a professional competence questionnaire after verifying the validity and reliability indicators. The initial questionnaire consisted of 32 items, with four items being removed due to redundancy, resulting in the final questionnaire containing 28 items. The researchers arrived at the following results: It emerged that the research sample perceives their teachers to have a good level of professional competence. There were statistically significant differences in the variable of gender, favoring male
Detection and Counting of Traffic in Two-Way and Four-Way Traffic Modes
No full textVehicle counting and detection using OpenCV is a vital computer vision application, enhancing surveillance and traffic control systems. By leveraging OpenCV’s capabilities, developers create systems to detect and track vehicles, including two-wheelers, using strategically placed cameras. Deep learning models like YOLO or pre-trained models such as Haar Cascade Classifiers identify vehicles within video frames, assigning bounding boxes to track movement across frames. This enables accurate counting as vehicles enter or exit the monitored area, with applications in toll collection, parking management, traffic flow analysis, and security. By precisely recognizing and tracking vehicles, these systems provide critical insights for traffic management, helping to reduce congestion, prevent accidents, and optimize parking usage. Additionally, they enable automatic vehicle tracking for security purposes, enhancing monitoring and safety. In summary, OpenCV’s application in vehicle detection and counting underscores the vast potential of computer vision technology in various industries
Synthesis and Characterization of Heterocyclic Compounds from Natural Carboxylic Acids: Evaluation of Their Antioxidant and Biological Activities
No full textHeterocyclic compounds derived from natural carboxylic acids have gained significant attention for their biological activities, yet their potential remains underexplored. This study focuses on the synthesis of benzimidazole derivatives (Z1-Z6) using adipic, citric, salicylic, oleic, tartaric, and hydroxy acetic acids with o-phenylenediamine. Characterization was conducted using FTIR and NMR spectroscopy. Antioxidant activity was evaluated in vitro via the DPPH assay, revealing significant scavenging activity for Z2 and Z4. Antibacterial activity against Staphylococcus aureus was assessed for Z3 and Z6 using the agar diffusion method, showing maximum inhibition zones of 22–24 mm at 800 µg/mL. These findings highlight the potential of these compounds as antioxidants and antibacterial agents, offering promising leads for further pharmaceutical development
Анализ Методов Оперативного Управления Минерально-Сырьевой Базой И Технологии Разработки Мелкомасштабных Месторождений Золота
No full textСтепень насыщения массива месторождения рудными телами и их сложная морфология требуют различного подхода к организации выемочно-погрузочных и транспортных работ. Для наиболее эффективного управления процессами и рабочим пространством карьера требуется объединять участки карьера в зоны со сходными природно-технологическими признаками и горно-транспортными работами. Для этого необходимо уделять особое внимание решению вопросов совершенствования методов оперативного управления минерально-сырьевой базой на основе применения динамических кондиций на открытых горных работах
Smart Learning as New Educational Model
No full textThe paper analyzes teachers’ and students’ attitude to a newly accepted SMART learning model, reveals peculiarities of SMART education. The conducted research allows drawing the following conclusions: teachers accept importance of SMART technologies and recognize the potential of SMART learning environment in improving the educational process quality, however, they failed to develop a subjective position on the problem of SMART technologies introduction
A Review of the System for Filtering Particulate Matter Affected by Cement Factor
No full textProblems with breathing or acute lung pain caused by cement specks in the air are common, and the cement producing industry typically has a hard time keeping them under control. Emissions control strategies can focus on preventing dust from being released into the air or on removing dust that has already gotten airborne. Space optimization, duct run length, dust collection procedure, and filter and control equipment selection are some of the primary factors that shape the design and fabrication of dust control systems
Prostate Cancer Key Risk Factors and Prevention Strategies
No full textProstate cancer is one of the most common types of cancer in men, affecting over 1.1 million individuals globally each year. Despite its potential to develop and spread, prostate cancer typically grows slowly. The disease is characterized by symptoms such as difficulty urinating and blood during ejaculation. Key risk factors include age (rare in individuals under 45 and increasing after 50), family history, race (more prevalent in Western countries and particularly among black individuals), hormonal influences (notably testosterone), diet (high in fats and low in vegetables), environmental factors, smoking, obesity, and pesticide exposure. However, the impact of these factors and the interplay between genetic and environmental influences remain underexplored. This study aims to identify and analyze the significant risk factors contributing to prostate cancer development. Methods involve a comprehensive review of existing literature and epidemiological data. Preliminary results indicate that heredity, lifestyle, and environmental exposures significantly contribute to prostate cancer risk. These findings underscore the need for targeted prevention strategies and public health interventions to mitigate the disease's incidence and improve patient outcomes
