METHODOLOGY OF OBTAINING CHROMIUM CARBONYL COMPLEXES AND DEVICES
USED IN OBTAINING THEM
Authors: Mehran Mammadli Mehran Mammadli
Published: May 2023

The development of modern technology and the long-term processing of materials and constructions used in high temperature conditions make great demands. It is very important to obtain hard-melting metals that meet these requirements. In nature, the scarcity of hard-to-melt metals and their high cost force us to find other more efficient ways. One such solution is the application of hard- -melt metals in the form of thin layers or coatings on metals or structures. For to this purpose, carbonyl compounds of hard-to-melt metals are widely used in technology recently. Carbonyl compounds have important properties, one of which is that they act as raw materials for obtaining coatings and layers through thermal decomposition. However, some difficulties arise in obtaining chromium coatings based on chromium carbonyl complexes with organic ligands. In order to overcome such difficulties, the synthesis methodology of two chromium-based complex compounds with easy volatility and low decomposition temperature, which are used in the production of corrosion-resistant coatings, and the temperature range in their decomposition limits, physical chemical structure parameters have been determined. The research found that both chromium carbonyl complexes obtained by synthesis form chromium coatings with high adhesion on the metal carrier and increase their corrosion resistance. Chromium carbonyl complexes can serve as technologically favorable raw materials for obtaining the necessary chromium coating during the decomposition of groups at a very low temperature range (100-150 C) without creating additional pressure. Both synthesized complex compounds are raw materials for obtaining corrosion-resistant coatings on weld seams of 09Г2С steel. The use of these complexes as active fillers in abrasive metallurgy has also been determined.

ANALYSIS OF METHODS FOR INCREASING THE SURVIVABILITY OF SMALL ARMS AND CANNON BARRELS BY THE APPLICATION OF CHROME COATINGS
Authors: Ismayilov Vugar Ismayilov Vugar
Published: May 2023

This paper is an analysis of modern chrome coating technologies for the barrels of small arms and cannons. Barrel survivability refers to the ability of a weapon system to fire a certain number of rounds without significant deterioration in ballistic characteristics. There are various methods to provide the necessary survivability of the barrels, both technological and constructive.
This paper will consider technological methods, in particular chroming technologies.
The objects of the research are various methods of chromium coating: electrolytic, cylindrical magnetron sputtering, galvanic honing, cathode-mechanical chromium plating, and thermodiffusion saturation by chromium.
Electrolytic chrome plating in baths is the most common method, however it has significant drawbacks - toxic waste, difficulty in providing uniformity and integrity of plating, hydrogen release during plating, the need for subsequent heat treatment of the barrel.
Coating barrels with cylindrical magnetron sputtering is one of the least studied methods, but from the available materials we can note the reduced toxicity and the absence of hydrogenation of the barrel and the plating. Nevertheless, the adhesion of the coating material and the barrel should be investigated.
Analysis of the thermodiffusion chrome saturation method is also a promising method. However, a reduction in temperature during the coating process and subsequent normalization of the coating is necessary. This method is currently being investigated in the "Special purpose product technology" laboratory at the Azerbaijan Technical University.
As a result of the research, the most prospective methods can be considered galvanic honing, the cathodic-mechanical method and thermodiffusion chrome saturation. The advantages of these methods are increased productivity and quality of the plating surface. In addition to the prospective chrome plating methods, the paper also noted questions for which the answers remain open.
Keywords: barrel, coating, chromium plating, wear, electroplating, magnetron sputtering, diffusion.

Published: May 2023

Business practices in areas like geographical information systems and environmental scanning are becoming more and more crucial, especially in light of the fierce competition in the technology sector. Organizations are less likely to hunt for information that they can act on right away than they are to experiment without trustworthy information, which results in organizational inattention. On the other hand, many companies are wasting money on initiatives that were either evaluated with insufficient data or that they were unable to absorb. In order to help enterprises design the best strategy for efficient environmental scanning and analysis, this study offers a new method based on environmental turbulence and aerial vehicles. Many businesses find it useful to measure the design of virtual models based on physical entities when creating their own virtual workshop models for scheduling and optimizing workshop production, but a single virtual workshop model cannot capture the interaction of physical and information objects necessary for intelligent manufacturing. To represent the fusion of virtual and real, however, and to therefore maximize the production of the workshop, the workshop for digital twins is an effective strategy. The digital twin system cooperative production unit is used as an example in this study to validate the suggested approach for building the digital twin workshop, which focuses on the definition and function of digital twin engines in a DT workshop.

Published: May 2023

Rail circuits are the basic elements of modern railway automation and telemechanics systems, performing the functions of track sensors and telemechanical channels. It is shown that the calculation of their operating boundary conditions becomes more complicated with the application of junctionless audio frequency rail circuits. The analysis of track circuits consists of studying the changes in their operation in various modes when the circuit parameters are changed. During the analysis, the optimal values of the parameters of the circuit elements and the frequency of the power source are determined for the given operating conditions. An analysis of the factors affecting the operating currents and voltages of such rail circuit schemes has been carried out. When analyzing and calculating a track circuit, it is assumed that the track line and equipment elements are linear, that is, their parameters do not depend on the flowing currents. To simplify the calculations, the track circuit is represented by the corresponding mathematical model (equivalent circuit) for each mode. Depending on the type of equivalent circuit used, four-pole and multi-pole models are distinguished. At the same time, the analysis and reporting of jointed rail circuits are carried out. Based on their results, the directions that allow for more accurate modeling of the operating modes of the circuits of the non-joint audio frequency rail circuits have been determined.
Keywords: Rail circuits, train traffic safety, audio frequency (no junction) track circuits, junction rail circuits, signaling system, track sensors, mathematical model, remote conditioning monitoring.

This study aims to find out the overview of  da'wah bil hal as an approach for proselytizing through actual actions or the role model from attitudes and behaviours represented in the religious film entitled "Merindu Cahaya de Amstel" by Hadrah Daeng Ratu. This research used the descriptive-analytic method to analyze the meaning of data in a movie using John Fiske's semiotic theory, which involve three levels, namely reality, including (1) appearance, costumes, environment, manner of speaking, gestures, and facial expressions; (2) representation, including, conflict, action and dialogue; and (3) ideology, the interpretations result of the fundamental level and representations categorized in social relations by ideological codes. The results showed that the da’wah bil hal approach in the movie "Merindu Cahaya de Amstel" was depicted through the appearance of the main character named Khadija, seen in her closed clothes (aurat). Besides, the way of speaking, gestures, and facial expressions revealed the personality of  Muslims who are polite,  helpful and have good respect for others. How Khadija's conflicts, actions, and dialogues are represented in this movie shows the characteristics of Muslims with a good character, balancing hablumminallah and hablumminannas, patience, devout worship, and always spreading usefulness. The practice of  da'wah bil hal or proselytizing through the figure of  Khadija, showed an ideology of religious humanism. The novelty of this research is the analysis of da’wah bil hal in a movie through the depiction of Muslim female characters applying Islamic values, including morals, trust, and worship.
Tourism Development Based on Religious Moderation in the Lake Toba Region Perspective of Communication Persuasion and Social Influence
Authors: Rasyid Abdul , Alfikri Muhammad , Stepani Riri
Published: May 2023

Domestic tourist objects which are considered to have attractive potential are visited by many Muslim tourists both from within and outside the country, but in reality these tourist objects pay little attention to the comfort of Muslim tourists. Visiting Lake Toba tourist destinations for Muslim tourists is not only about natural beauty, but also about halal food and comfortable places of worship. Halal tourism continues to be an interesting issue to discuss because it is a vital issue for the life of Muslims. It is very risky for Muslims when a tourist destination does not provide comfort regarding the issue of halal food and the availability of places of worship. This paper reviews the concept of religious moderation tourism which can be interpreted as the availability and fulfillment of the needs of Muslims and tourist destinations such as halal food that is not mixed with unclean food, proper places of worship, and various other facilities that are the needs of Muslims. The approach used in this study is a qualitative approach. Data were obtained by conducting interviews with tourism managers, community leaders, the Head of the Culture and Tourism Office, tourism observers and the community. The concept of moderating religious tourism in the Lake Toba area is already underway, such as hotels serving halal food cooked by Muslim workers, providing prayer rooms. However, what has not been seen is the certainty of food halalness with the existence of a halal certificate issued by the competent authority. The facts obtained in the Lake Toba area did not play much of a role in changing the attitudes and behavior of local residents to become more moderate towards foreign Muslim tourists.

Affluenza affects not only the general public, but students at Pondok Pesantren Nurul Jadid, Paiton are also affected by affluenza. Simple synonymous students become luxurious lives. Like buying stuffbrandedAccording to some foster parents, many students experience that their intensity is recognized. To overcome this, the advice from the Kyai alone is not enough; intensive guidance and treatment are needed; Foster parents help the Kyai in guiding and educating the santri, and the role of communication is very influential in overcoming affluenza, especially interpersonal communication. Researchers used descriptive qualitative methods; data were analyzed using Harold Granfinkel's ethnomethodology and Ekman Friesen's functionalist structure. The results in this article show that in dealing with student affluenza, foster parents use two models of interpersonal communication: 1). Interpersonal (verbal) communication, foster carers provide understanding and advice regarding the dangers of affluenza and foster carers also try to find out what the reasons are for students suffering from affluenza. 2). Interpersonal communication (Nonverbal) foster carers also use nonverbal communication such as stroking the head, holding the shoulder, smiling, where the meaning of this nonverbal communication is to replace, emphasize and support verbal messages.

Published: May 2023

This research focuses on how journalists at Nahdlatul Ulama (NU) Online Media in East Java construct news presented to the public about religious moderation. It showcases news framing on religious moderation from the perspective of Nahdlatul Ulama through online media in East Java. This research aims to understand how NU's religious moderation is disseminated in society through media produced by journalists. The research method employed is qualitative, utilizing media text analysis with framing by Zhondang Pan and Gerald M. Kosicki, analyzing four syntactic structures: script, thematic, and rhetorical. The research also involves validation of the truth and news construction with the editorial board of NU Online East Java. The results of this research explain that journalists at NU Online East Java construct news on religious moderation by presenting the teachings of Ahlus Sunnah Wal Jamaah Nahdliyah through the practice of Hubbul Watan Minal Iman (Love of the Homeland is Part of Faith), with the vision of Islam as a mercy to all creations (rahmat lil 'alamin). Conflicts arise in online media concerning narratives of violence, liberalization, and radicalism. Consequently, journalists construct the values of religious moderation from the perspective of NU figures, namely Alisha Wahid and Gus Miftah, to create alternative narratives in online media that promote positive content rather than content that divides intergroup relationships.

Gallbladder torsion in a child diagnosed by ultrasonography and treated by laparoscopic cholecystectomy
Authors: Nguyen Anh
Published: May 2023

ABSTRACT Gallbladder torsion is a very rare cause of acute abdominal pain. It usually occurs in elderly women, when the gallbladder twists around its mesentery. Contributory factors for this to occur are postulated to be an associated anatomical abnormality of the vascular pedicle to the gallbladder or the presence of an abnormally long mesentery from the gallbladder to the liver bed allowing it to float freely. Clinical symptoms are nonspecific, usually similar to biliary colic with acute onset of abdominal pain, nausea and vomiting. The absence of gallbladder stone with signs of acute cholecystitis on imaging findings can suggest a torsion of the gallbladder. This disease is a life - threatening emergency that requires urgent cholecystectomy. However, cases of gallbladder torsion in children undergoing laparoscopic cholecystectomy are rarely reported nationally or internationally due to the uncommonness of the disease. We report a 3 - year - old child admitted to the hospital with symptoms of acute abdominal pain and vomiting. Ultrasonography demonstrate a distended gallbladder, with a multilayered wall, which contained no stones. Laparotomy was performed and the gallbladder was found to be twisted around its pedicle. Cholecystectomy was performed. After surgery, the child was stable and was discharged from the hospital after 5 days of treatment.
Analysis of EGFR gene mutation in patients with Non-Small cell lung cancer in Hue Central Hospital
Authors: Pham Cuong
Published: May 2023

ABSTRACT
Objective: To analyze the EGFR mutation index on the cancer blocs of the patients with non - small cell lung cancer (NSCLC) at the Department of Pathology - Hue Central Hospital.
Subjects and methods: A prospective, cross-sectional descriptive study of 227 patients with advanced, metastatic non - small cell lung cancer who were mutated in the EGFR gene. The study were carried out on the cancer parrafin blocs stored in Pathology Department, Hue Central Hospital.
Results: Mean age 58.29 ± 9.36 years old, male/female ratio 1.58. Histopathology is mainly adenocarcinoma: 96%, squamous epithelium: 0.9%, large cell: 3.1%. EGFR mutation rate positive 38.3%, negative: 61.7%. The rate of positive EGFR mutations in women: (53.4%) is higher than in men: (28.8%). The rate of positive EGFR mutations in the smoking group: (24.4%), insignificant smoking: (32.8%), the non - smoking group (56.6%). The cases of patients carrying mutations in EGFR gene have 50.6% of LREA deletion mutations in exon 19; 40.23% are L858R substitution mutations in exon 21; 3.45% are G719X mutations and 2.3% are G719S mutations in exon 18; 1.14% are Q787 mutations in exon 20; 1.14% are double mutations S768I + V769L in exon 20 and T790M + L858R in exons 20 and 21.
Conclusion: The rate of EGFR gene mutation in NSCLC patients was 38.3%, higher in women than in men and especially high in non - smokers or non - smokers, the difference was statistically significant with p. < 0.05. The most common TKI - sensitive mutations include deletion mutations in exon 19 and substitution mutations in exon 21 (accounting for more than 90%), a percentage less than 5% are mutations.

Published: May 2023

Aim: to evaluate demographic and disease characteristics in pulmonary arterial hypertension associated with connective tissue disease (PAH-CTD) patients.

Materials and methods: the study enrolls 68 patients with PAH-CTD. These patients were diagnosed in department of pulmonary hypertension and heart disease of the E.I. Chazov National Medical Research Centre of cardiology. Clinical, functional and hemodynamic characteristics of PAH patients were examined. The diagnosis was confirmed according to Eurasian (2019) and Russian (2020) guidelines for the diagnosis and treatment of pulmonary hypertension.

Results: Of 68 patients with CTD 35 (51,5%) had systemic sclerosis, 11 (16,2%) - mixed CTD, 22 (32,3%) - other CTD. The median time from PAH onset to first visit to health care worker was 4 months, the median time from first visit to PAH diagnosis was 7,5 months. The median age was 59,5 years, 94,1% patients were women. The median 6-minute walking distance (6MWD) was 345 (259,25-400,00) m, which was corresponding to WHO functional class III, the median Borg dyspnea index was 5 (3,0-6,0). 12 (17,7%) patients did not undergo 6MWD due to severity of their condition. According to right heart catheterization data the median mean pulmonary arterial pressure was 51,0 (35,5-62,0) mmHg, the median cardiac index was 2,1 (1,7-2,5) liter/min/m2, the median pulmonary vascular resistance was 11,48 (5,99-15,71) Wood units. According to several risk stratification calculators, the vast majority of patients were at high risk of 1-year mortality: due to risk status, PAH-specific therapy was initiated to 88,3% patients: 42,7% received double and 8,8% - triple PAH-specific therapy.

Conclusions: In Russian clinical practice, PAH-CTD is characterized by late- onset diagnosis. Newly diagnosed patients have significant functional and hemodynamic impairment, high risk of 1-year mortality, which results in combined PAH-specific therapy initiation.
