В работе исследованы эпоксидные связующие на основе смолы ЭД-20 и отвердителей Л-19, Изофорондиамин и Джеффамин D-230. Цель работы исследование реологических и физико-механических свойств образцов связующего. Каждое связующее было приготовлено в соответствии с рекомендуемым соотношением. Изменение вязкости связующего определяли на ротационном вискозиметре. Отверждение всех образцов проводили в одинаковых режимах (2 ч при температуре 23С, затем 4 ч при температуре 60С). Прочность образцов при растяжении определяли по ГОСТ 11262-2017. Связующее на основе отвердителя Л-19 имеет самую высокую начальную вязкость и низкую живучесть, а связующее на основе Изофорондиамина вполне пригодно для формования композитов (живучесть - 90 мин). Самую низкую вязкость и высокую жизнеспособность имеет связующее на основе Джеффамина более 5-ти ч. Отвердитель Л-19 малопригоден для изготовления стеклопластиков, так как связующее на его основе имеет прочность 15 МПа. Связующее с Изофорондиамином имеет прочность 23,4 МПа. Связующее с Джеффамином имеет наиболее высокую прочность 50 МПа и приемлемую деформативность, что наряду с хорошими реологическими свойствами позволяет рекомендовать его для изготовления композитов методом мокрой намотки.

Here we explore epoxy binders based on resin ED-20 and curing agents L-19, isophorone diamine and Jeffamine D-230. The study aimed at investigating rheological and physicomechanical behavior of the binder specimens. Each binder specimen was fabricated with the recommended component ratio. The variation in viscosity of the binder was determined on a rotational viscometer. All the specimens were cured under the same conditions (at 23С for 2 h, and then at 60С for 4 h). The tensile strength of the specimens was measured as per GOST-R 11262-2017. The L-19-based binder had the highest initial viscosity and lowest survivability, while the isophorone diamine-based binder was quite suitable for molding the composites (90 min survivability). The lowest viscosity and highest survivability (over 5 h) were demonstrated by the Jeffamine-based binder. Curing agent L-19 is less suitable for fabricating glass fiber-reinforced plastics, as this binder has a strength of 15 MPa. The isophorone diamine-based binder exhibits a strength of 23.4 MPa. The Jeffamine-based binder has the highest strength of 50 MPa and an accaeptable deformability, which, together with good rheological behavior, allows it to be advised for making composites by the wet filament-winding technique

Authors: Федоренко Е.И. , Анфилов К.Л.
Published: October 2024

Исследовано влияние некоторых органических аминов различного строения на коррозию низкоуглеродистой стали в 2 М HCl, H2SO4 и H3PO4 (25÷95 ℃). Наиболее высокие результаты в замедлении коррозии стали позволяет получить третичный диамин, содержащий в своем составе более объемные заместители. На основе этого соединения разработаны ингибиторные композиции для защиты низкоуглеродистой стали в растворах минеральных кислот. Эти ингибиторы коррозии во многом перспективны для защиты стального оборудования, применяемого на предприятиях нефтегазового комплекса, в случае его потенциального контакта с растворами кислот. Они защищают низкоуглеродистые стали в наиболее востребованных минеральных кислотах (HCl, H2SO4 и H3PO4) в широком диапазоне температур (25÷95 ℃), что крайне важно при промышленном использовании ингибиторов кислотной коррозии. Высокое защитное действие разработанных ингибиторных композиций при коррозии стали в растворах минеральных кислот подтверждается эффективным торможением ими катодной и анодной электродных реакций металла. При этом, смесевые ингибиторы преимущественно замедляют анодный процесс.

The effect of some organic amines of various structures on the corrosion of low-carbon steel in 2 M HCl, H2SO4, and H3PO4 (25–95 ℃) was studied. The highest results in slowing down the corrosion of steel allows one to obtain a tertiary diamine containing more voluminous substituents. Based on this compound, inhibitor compositions have been developed for the protection of low carbon steel in solutions of mineral acids. These corrosion inhibitors are largely promising for the protection of steel equipment used in the oil and gas industry in case of potential contact with acid solutions. They protect low-carbon steels in the most popular mineral acids (HCl, H2SO4, and H3PO4) over a wide temperature range (25–95 ℃), which is extremely important for the industrial use of acid corrosion inhibitors. The high protective effect of the developed inhibitory compositions upon corrosion of steel in solutions of mineral acids is confirmed by their effective inhibition of the cathodic and anodic electrode reactions of the metal. In this case, mixed inhibitors mainly slow down the anode process.

Рассмотрен вопрос повышения эффективности информационно-измерительной системы управления воздушным движением на примере синтеза алгоритмов функционирования угломерного канала при сопровождении воздушного судна с учетом информации его бортовых датчиков (кинематические и динамические параметры), которая позволяет более точно описать модель движения воздушного судна относительно ИИС УВД, по сравнению с существующими моделями. Это приводит к улучшению точностных характеристик угломерного канала. Точностные характеристики ИИС влияют на пропускную способность и безопасность управления воздушным движением. Обосновывается выбор моделей состояния и наблюдения, разработан алгоритм функционирования угломерного канала, проведено имитационное моделирование на ЭВМ и получены результаты исследованных алгоритмов. Результаты исследованных алгоритмов могут быть использованы при проектировании и разработке перспективных информационно-измерительных систем управления воздушным движением.

The issue of improving the efficiency of the information and measurement system for air traffic control is considered on the example of the synthesis of algorithms for the operation of the angle channel when escorting an aircraft, taking into account the information from its onboard sensors (kinematic and dynamic parameters), which allows more accurately describing the model of aircraft movement relative to the ATC AIS, in comparison with existing models. This leads to an improvement in the accuracy characteristics of the angle channel. The accuracy characteristics of the AIS affect the throughput and safety of air traffic control. The choice of state and observation models is justified, an algorithm for the operation of the angle channel is developed, computer simulation is performed, and the results of the studied algorithms are obtained. The results of the studied algorithms can be used in the design and development of advanced information and measurement systems for air traffic control.

Authors:   KOREA CPTED ASSOCIATION, Hong Sung-Jin , Lee Kyung-Hoon , Jang Kwang-ho
Published: October 2024

This study is to examine the vulnerable environmental factors in university Crime Hot-Spot Area through campus field surveys and the correlation between safety system and statistical analysis. Seven campuses were used for current research wity using the data of 112 crime data with 1,793 crimes.
We then analyzed Crime Hot-Spot Area through the Geographic Information System(GIS). For each university, vulnerable elements were derived in terms of the geographical characteristics of Crime Hot-Spot Area, the use of academic buildings, and the environmental design for crime prevention(CPTED). Crime Hot-Spot Area includes border areas(Edge effect) such as campus entrances, libraries, living halls, and student halls, as well as hospitals and parking lots on campus, nearby bus stops, and subway routes. Multiple regression analysis was conducted on seven independent variables related to vulnerable factors using the number of crime hot-spots as a dependent variable.
The independent variables are the measured distance between the 112 report location and the CCTV, lighting, emergency bell, campus entrance, and general situation room. In addition, the correlation between the integration value of crime occurrence locations and the connection value through Space-Syntax analysis was also analyzed. The higher the number of Crime Hot-Spot Areas, the higher the integration value and the lower the connection value. Crimes have been concentrated on streets with high centrality and low connectivity on campus and streets with the characteristics of traveling in one direction. CCTV is a physical surveillance system known to be effective in crime prevention, but in this study, on the contrary, CCTV was installed closer as the number of occurrences in Crime Hot-Spot Areas increased. Lighting(CPTED surveillance index) was also related to crime occurrence in the analysis results of only one out of seven universities. Therefore, it was difficult to see lighting as an indicator related to campus crime prevention.
It is important to analyze 112 police report data on important crimes such as theft, sexual violence, and violence that actually occurred on campus to derive accurate hotspot areas suitable for environmental characteristics. In the future, the results of this study that fit the characteristics of the university campus can be used.
ENSURING JUDICIAL INDEPENDENCE BY EVALUATING THE RECRUITMENT PROCESS AND LEGAL FRAMEWORK FOR JUDGES IN INDONESIA
Authors: Sukmariningsih Retno Mawarini , Nurudin Agus , Irawan Benny Bambang , Riyanto Ontran Sumantri
Published: October 2024

As the highest judicial institution, the Supreme Court exercises its powers freely and independently. Judges must have morals, principles of justice, and adhere to a code of ethics. Judges must uphold justice in resolving disputes or legal cases and ensure that society receives justice. As state officials, the recruitment process for judges should be separated from the recruitment of civil servants. The position of judges as state officials should be regulated comprehensively by law. This research examines the recruitment process of judges as independent implementers of judicial power. The research method used is descriptive, using qualitative data analysis with a normative juridical approach. Supreme Court Regulation Number 1 of 2021 concerning Amendments to Supreme Court Regulation Number 2 of 2017 concerning the Procurement of Judges regulates the need for judges in General Courts, Religious Courts and State Administration through the acceptance of Candidates for Civil Servants that needs to be improved. This need arises because there are no legal provisions regarding the recruitment of judges as state officials. In the future, provisions for the recruitment of judges should be regulated through Government Regulations so as not to impact the independence of judges as implementers of judicial power.

Published: October 2024

Customary law in the national legal system is undoubtedly fundamental to maintaining existence because customary law can also be applied to resolve conflicts in society. This research uses socio-legal methods, and the data obtained is based on data in the field through an interview process with several related parties. In contrast, for legal problems in this society, only some things can be resolved through a customary law approach. For example, in the Dayak indigenous community, several legal problems cannot be resolved according to custom, especially regarding unregistered land rights. These problems certainly cannot be solely resolved using a customary law approach. This certainly shows that customary law cannot necessarily accommodate the interests of Indigenous peoples because this is also closely related to legal certainty. Because they relate to legal certainty, they must be resolved through a positive legal approach, such as submitting a request to the court or an application to the relevant agency. This certainly happens because the legal awareness of regional communities in Indonesia is currently not very good; this leads to legal issues within indigenous communities that cannot be resolved through customary law.

Authors: Du Guo , Jin Gang
Published: October 2024

Objective: To analyze the effect of the blood glucose gap on post-stroke cognitive impairment in acute ischemic stroke patients. Methods: 300 stroke patients admitted to the hospital between December 2021 and December 2022 were selected and divided into three groups according to the value of blood glucose gap: the group with no elevation of blood glucose gap (n = 124), the group with mild elevation of blood glucose gap (n = 97), and the group with elevated blood glucose gap (n = 79). The same treatment regimen was applied to these three groups and cognitive function was assessed using MMSE and MoCA at 3, 6, and 12 months after discharge. Results: The NIHSS and MoCA scores of the patients in the group with elevated blood glucose gap were significantly higher than those in the mildly elevated group and the non-elevated group at 3, 6, and 12 months after discharge, and the MMSE and MoCA scores of the patients in the group with mildly elevated blood glucose gap were significantly higher than those in the non-elevated group at 3, 6, and 12 months after discharge, and there were statistically significant differences between all the groups (P < 0.05). Conclusion: Patients with an elevated glycemic gap in acute ischemic stroke showed more pronounced cognitive impairment than those with no elevated glycemic deficit, and the severity of cognitive impairment increased with the degree of glycemic deficit.
Methods for Fabrication of Self/Free Standing Nanocellulose (NC)-Nano Montmorillonite (N-MMT) Composite Films/Sheets — A Review
Authors: Shanmugam Kirubanandan
Published: October 2024

Plastic pollution looms large as a formidable foe to the environment. Enter cellulose nanofibers, the shining stars in the quest for innovative, eco-friendly paper-based packaging that is not just renewable, but also recyclable and biodegradable. These cellulose wonders boast impressively low oxygen permeability, but when it comes to water vapor, they fall short compared to traditional packaging plastics like LDPE. To tackle this challenge, researchers have been crafting composites by blending cellulose nanofibers with inorganic nanoparticles, such as Montmorillonite clay, which helps to curb water vapor permeability. However, this clever addition comes with a catch — it further complicates the already tricky drainage process during layer formation via vacuum filtration. This review delves into the complex world of nano cellulose-nano-MMT (Montmorillonite) composites, examining their preparation processes, unique characteristics, wide-ranging uses, and their significant contribution to promoting circular economy principles. By combining cellulose nanomaterials with MMT, a synergistic approach is taken to develop a new composite material with improved mechanical, thermal, and barrier properties. Various fabrication techniques are explored, including solution blending, in-situ polymerization, and electrospinning, allowing for customized design and optimization of the composite material. The review discusses how the nano cellulose-MMT composite demonstrates enhanced mechanical strength, thermal stability, and barrier properties, positioning it as a sustainable option compared to traditional materials. The review also showcases the diverse applications of these nano-composites in fields like packaging, biomedical devices, and environmental cleanup, emphasizing their alignment with circular economy principles. By examining the entire life cycle of these composites, from production to use and eventual disposal or recycling, the review underscores their role in supporting a circular economy. In light of the ongoing efforts by the scientific community and various industries to identify environmentally sustainable solutions, it is imperative to comprehend the synthesis, properties, and applications of nano cellulose-MMT composites. This understanding is essential for advancing sustainable processing for green material development.

The present tea production technology is extensive and unsanitary as tea processing has the issues of easily mixing in hair, animal hair, and other debris problems. The production enterprises can only use a large number of workers to manually sort the tea, requiring large labor for low efficient and unideal sorting results. Hence, tea production enterprises urgently need to solve this problem to meet the product to meet the quality requirements of health food. In this paper, the design and development of the vibration motor of the key components in the tea impurity removal unit were studied. The specific work is as follows. The dynamic analysis of the movement of the material on the vibrating working surface is performed, the motion state of the tea declutter vibration machine is determined as throwing motion, and the structure scheme of the elastic link eccentric type vibration machine is designed. The structure scheme of the elastic link eccentric vibration motor was modeled by Inventor 3D design software, and the suitable parameters were selected for trial production of a prototype.

Authors: Tian Hui
Published: October 2024

The chamber of commerce is a powerful support to serving the government and managing the non-public economy, which can strongly promote the high-quality development of the private economy in Shaanxi. In recent years, Shaanxi has made multiple overall plans and taken multiple measures to improve the vitality of the development of the chamber of commerce in an all-around way, enabling the high-quality development of the private economy with policy integration and innovation. However, there are still problems in the development of chambers of commerce, such as a lack of public service awareness, lack of institutional norms, uneven levels of development, and lack of unified centralized management. Therefore, this paper puts forward four countermeasures and suggestions. First, clarify the boundary of power and responsibility, and effectively exert the function of the federation of industry and commerce. Second, strengthen the legal guarantee and support of norms and policies. The third is to improve the level of autonomy of chambers of commerce and enhance the development in all aspects. Fourth, build a new type of government-business relationship and continuously improve the market business environment.

Authors: M Kamal Dhafer , A. Fakhroo Fatima
Published: October 2024

Blunt carotid artery injury (BCAI) is a rare sequelae of blunt neck trauma. It may lead to stroke and major neurological deficits. Therefore, early diagnosis and management are crucial to prevent or reduce associated morbidity. We report a 22-year-old male who sustained an accidental left BCAI with an air-gun bullet. The injury was suspected on clinical assessment and confirmed by a CT/angiogram of the neck. The patient was promptly started on therapeutic anticoagulation and did not develop any neurological deficits. Our case emphasizes the importance of non-invasive management of BCAI, which requires a high index of clinical suspicion for diagnosis. Once confirmed, starting therapeutic anticoagulation early is vital to avoid fatal consequences, namely strokes, in such patients. Keywords: Blunt injury; Carotid artery; Stroke; Anticoagulation; Vascular Trauma

The purpose of the study is to develop a classification of leadership styles based on a combination of two indicators: the degree of employees’ involvement in the decision-making process and the prevailing orientation at the enterprise either towards achieving organizational results or towards ensuring employees’ satisfaction. The scientific novelty of the work is in the approach to solving the stated problem, namely, the creation of the authors’ typology of management styles (individual authoritarian, paternalistic, collective, communal), based on a combination of the degree of staff participation in making management decisions and target orientation towards business/relationships. The results obtained show that this methodology helps to reveal most efficiently the features of management at modern Russian enterprises. This methodology was used as a basis for the analyses of the aspects determining the nature of the leadership. There was revealed its relationship with various socio-economic factors. Long-term longitudinal studies conducted at Naberezhnye Chelny enterprises provided the authors of the article with empirical material, on the basis of which it was concluded that authoritarianism and paternalism were the most characteristic of the modern domestic managers’ style. The practical significance of the study is in the possibility of applying its results at enterprises in various sectors of the economy. The proposed classification of management styles can be used as a methodological toolkit in studying the effectiveness of management work at different organizations, as well as in the process of training, retraining and advanced training of personnel.
