INFORMATION MODELING OF CONCRETE: CURRENT STATUS AND DEVELOPMENT PROSPECT S
Authors: Makeev Aleksey
Published: December 2023

The publication relates to the problems of digitalization of building materials science. The relevance of developing a digital model of concrete for solving optimization problems of design and synthesis of its structure, clarifying methods for calculating building structures, and improving the technology of their production is shown. The evolution of information modeling of concrete is analyzed in the context of the stages of development of system-building materials science and technology.

A review of the main modern methods of computer modeling of concrete structure in domestic and foreign scientific research is provided. It is noted that these methods do not take into account the complexity of the structure of concrete. In the article, concrete is presented as a conglomerate composite with a hierarchically organized structure with dimensions from 10-10 to 10-1 m. It has a minimum of 5-6 scale levels and three types of substructure design. Substructures differ in their scale, genesis and mechanics of manifestation of properties. The first type of substructure is characteristic of the macro-, meso- and micro-scale levels. It is accepted in the form of a two-component “construction” of a spatially continuous matrix and discrete inclusions deterministically and stochastically distributed in it. The second type refers to the submicro-, ultra-micro- and nanoscale levels. It is believed to be in the form of a “microscale spatial structure” of new formations of a cementing substance from consolidated individual crystalline differences. The third type corresponds to the atomic-molecular structure of new formations of the cementing substance.

The characteristics of each type of substructure are given according to: the scale of the components; features of formation; mechanics of properties manifestation; design criteria; means of synthesis. An assumption is made about the specificity of modeling each of the three types of concrete substructures and their integration into a single digital model. The task is to develop an information platform for such a model. The platform should include: a theoretical knowledge base; empirical data base; database of analytical, numerical and statistical models; algorithms for designing and synthesizing structures; optimization criteria and boundary conditions; terms of reference for computer modeling of concrete.
EL DESARROLLO ECONÓMICO Y CHILE
Authors: Ffrench-Davis Ricardo
Published: December 2023

En este ensayo efectúo un recuento breve sobre en qué consiste el desarrollo económico; sus efectos y sus fuentes. Expongo los fuertes altibajos en el grado de progreso de Chile desde 1973 hasta el presente, y esbozo cómo se podría lograr avanzar a partir del nivel de desarrollo actual de la economía nacional. Lo ilustro con algunas propuestas de reformas de políticas públicas a priorizar y coordinar, para recuperar sostenibilidad del crecimiento y reforzar la inclusión. En el camino muestro cómo dos creencias difundidas en ciertos sectores son meras creencias sin sustento real: un supuesto éxito de la dictadura en lograr crecimiento sostenible y desarrollo, y la creencia de que rigió un modelo único en los “30 o 50 años”.
CHILE Y LA INTEGRACIÓN REGIONAL EN CINCUENTA AÑOS
Authors: Sáez Raul
Published: December 2023

Uno de los pilares de las reformas económicas refundacionales de la dictadura militar fue la reforma a la política comercial. Esta empezó tempranamente cuando apenas cuatro meses de tomar el poder se anunció la eliminación y reducción de las múltiples barreras arancelarias y no arancelarias que impedían las importaciones. Dado que la nueva política comercial chocaba con la del Pacto Andino del cual Chile era miembro fundador, en 1976 se acuerda su retiro del bloque. Chile no vuelve a ser activo en la integración regional latinoamericana sino hasta el retorno de la democracia en 1990. En este documento se aborda la relación entre Chile y otras instituciones de integración latinoamericana durante el régimen militar para luego analizar la historia de las negociaciones acuerdos bilaterales ya sea con países de la región latinoamericana o de fuera de ésta durante los últimos 33 años. Destacamos los factores que contribuyeron a una exitosa reinserción regional de Chile en América Latina, sin dejar de lado la inserción global lograda, y simultáneamente expandiendo la profundización de las relaciones económicas con economías en cuatro continentes con acuerdos de libre comercio complejos. Al restablecerse la democracia, Chile no tenía acuerdos de libre comercio, actualmente tiene 27 acuerdos de libre comercio con 63 economías. Simultáneamente, el porcentaje de exportaciones de Chile reguladas por un acuerdo de libre comercio aumentó de 0% en 1990 se llega a 94% en 2022. Otro aspecto destacable y, responsable del éxito, es que se mantuvo la continuidad de esta política por 30 años.

Authors: Bergoeing Raphael , Romero Cristián
Published: December 2023

En este trabajo se describe y analiza el sistema de permisos para la inversión en Chile. Estos permisos, que buscan resguardar materias tan relevantes como la salud y seguridad ciudadanas, si están mal diseñados o implementados pueden transformarse en una barrera al desarrollo, incluso sin cumplir su objetivo público primordial. En particular, el sistema de permisos en nuestro país es ineficiente, incierto e inestable; perfeccionarlo permitiría mejorar el funcionamiento de ambos, el Estado y el mercado. Y esto es clave, porque en una economía moderna, si uno de ellos falla, todo falla.

The remote assessment of methane (CH4), nitrogen dioxide (NO2), and sulfur dioxide (SO2) concentrations in the atmosphere of oil-and-gas profile settlements within the Yamalo-Nenets Autonomous Okrug for 2019–2022 was made for the first time. Data analysis from the TROPOMI spectrometer revealed that the highest levels of atmospheric pollution are observed near industrial centers and major cities (Novy Urengoy, Salekhard, Nadym). Increased impurities were identified along gas pipelines (near compressor stations). The highest average values of nitrogen dioxide content were recorded in Novy Urengoy (1,34 mol/m², with contamination peaks occurring in winter months). Excessive concentrations of sulfur dioxide were found in urban-type settlements. The highest average values were recorded in Stary Nadym (20,35 mol/m²). The maximum methane content (1866,2 ppb) was reported in Novy Urengoy. Urban air, in general, has increased methane content. However, focuses of its spread are also observed beyond cities, which may be a consequence of global warming

Authors: Pradhananga Manisha , Raitzer David A. , Sebastian-Samaniego Iva , Naval Daryll
Published: December 2023

The Sixth Assessment Report of the Intergovernmental Panel on Climate Change incorporated an ambitious model intercomparison effort that compiled thousands of model-scenario combinations to consider low carbon development pathways. This paper explores the evidence within that database to consider decarbonization pathways for developing Asia. Overall, a comparison of the major models finds strong consistency in the transformation of the energy sector required to achieve Paris Agreement goals. This includes a rapid decline in the share of coal—a mainstay of the power sector in developing Asia— and a substantial rise in renewable energy. The cost of the transition can be relatively low if mitigation efforts are efficient, as assumed in the models.

Authors: Norouzi Masoud , Caferov Elbrus
Published: December 2023

The development of control systems for aerial vehicles necessitates a meticulous examination of their dynamic behavior. This research delves into an in-depth investigation of the dynamic behavior of the F-16 aircraft, employing refined mathematical models to analyze both its longitudinal and lateral motions, as well as their corresponding modes. These mathematical models are formulated in two conventional representations: state space equations and transfer functions. By utilizing these mathematical representations, two displacement autopilots have been developed, consisting of a pitch attitude autopilot based on the longitudinal equations and a roll attitude autopilot designed using the lateral equations. Proportional Integral Derivative (PID) controllers, encompassing inner loops, as well as Linear Quadratic Controllers (LQR), have been recruited as control system units. The control structures have undergone analysis utilizing Simulink models. The analyses have yielded favorable damping characteristics and faster responses in both longitudinal and lateral movements and modes.

Authors: Malayev Niyaz , Saparbayev Samat , Kubekova Saule , Zhampeissov Nurlan
Published: December 2023

Liver cancer is characterized by high mortality and low survival rates in most countries of the world. According to the WHO data, more than 1.3 million people with liver cancer die annually in the world and according to the data of the 9th volume of "Cancer on five continents" - the highest standardized incidence rates are in Korea - 44.9 per 100 thousand population as well as in Thailand, Japan, China. Low rates were in Algeria, India, Belgium and the Netherlands. In Russia 61.5% of patients die of liver cancer progression in the first year after diagnosis [1,2].

Information on the global burden of cancer in 2018 showed that the specific weight of liver cancer in the structure of malignant neoplasms (MN) is 8.2%, and in 2020 - 8.3% [3].  

The worldwide peculiarity of liver cancer is its late diagnosis. Several evidence-based treatment options for liver cancer are currently available: liver transplantation for hepatocellular liver cancer (HCC) (according to the Milan criteria), radiofrequency ablation as a radical treatment option (RFA), chemoembolization for intrahepatic cholangiocarcinoma (TACE), and the administration of Sorafenib as systemic therapy [4].

Current approaches for the treatment of early-stage primary liver cancer are represented by hepatic RFA, and the efficacy of this approach depends on the subjective attentiveness and visual acuity of the clinician. The latest technique used in liver RFA is the hyperspectral imaging which utilize objective assessment [2].

Ultrasound is usually used to detect liver lesions, but the detection rate is low for many reasons, such as clinician skills and technical capabilities. Modern approaches of diagnostic capabilities, such as contrast-enhanced ultrasound integrated imaging (CEUS) and comprehensive ultrasound imaging - contrast-enhanced CT (CECT) or contrast-enhanced MRI (CEMRI) for visualization of focal liver lesions (FLL) - increase the confidence of the interventional physician so it should be recommended for use as a routine procedure [5-6].

The ratio of morbidity and mortality in many countries reaches 91.6%, which represents the third most important cause of cancer deaths [7-9].

Authors: Baiterek Bekzat , Mustafin Alibek
Published: December 2023

Introduction: Cardiac surgery is a dangerous and complex field of medicine with significant morbidity and mortality. Quality anesthetic care with specific attention to detail can greatly enhance patient safety and outcome.
 Objectives: Comparison of the effects of anesthetics on oxygen consumption, transport and energy expenditure during coronary artery bypass grafting in adults.
 Material and methods: A total of 90 patients were assigned randomly into three groups according to the type of anaesthesia: the first group with propofol (P), the second group with sevoflurane, and the last one was with isoflurane. All patients underwent coronary artery bypass grafting under cardiopulmonary bypass. To determine oxygen delivery and oxygen consumption were determined using the formulas ((DO2 = CI* CaO2), (VO2 = Cardiac index (CI)) and a spirometric device during anaesthesia.
 Results: the cardiac index remained at the same level in the propofol and sevoflurane groups (2.5±0.6 l/min/m2 and 2.3±0.5 l/min/m2), while in the isoflurane group it was decreased to 2.3±0.5 l/min/m2. The oxygen transport index was 421.6±57.0 ml/min/m2 in the propofol group, 396.4±63.2 ml/min/m2 in the sevoflurane group, and 376.7±68.0 ml/min/m2 in the isoflurane group. Propofol reduced oxygen consumption to 101.5±23.5 ml/min/m2, while sevoflurane and isoflurane anesthesia reduced it to 106.6±22.3 ml/min/m2 and 116.4±21.4 ml/min/ m2. All anaesthetics reduced energy expenditure, but propofol anaesthesia significantly reduced it from 1491.4 to 1188.3 kcal/day.
 Conclusion: In conclusion, isoflurane significantly reduced cardiac index compared to propofol and sevoflurane. Oxygen transport was higher in the propofol group than volatile anesthetics, and propofol reduced oxygen consumption more than inhalational anesthetics. In addition, energy expenditure was lowest in the propofol group than in the other anesthetics.

Authors: Putri Renny Eka , Geraldo J P , Andasuryani Andasuryani
Published: December 2023

Yield monitoring is a precision farming technology that monitors crop yields in real-time. The cutting width is one of the variables gathered by yield monitoring. The cutting width is measured using the sensor by subtracting the width of the header from a distance reading from the sensor to the rice installed on the left and right sides of the mini combine harvester header. This research aims to design a cutting width measurement system using the VL53L1X ToF sensor on a mini combine harvester. The VL53L1X ToF Sensor is used as a distance sensor, followed by an ESP-32 microcontroller and a WiFi module. These are linked to the database and interpreted into digital form using an I 2 C LCD so that the user may see the results afterward. The accuracy of the two sensors (left and right) is evaluated by comparing distance measurement results on an object with an R 2 value of 1. For static testing on rice plants (Oryza sativa L), ten data collecting variations with three repetitions were conducted, with an average R2 of 0.9975 throughout the three repetitions. The dynamic test system includes an Ublox GPS tracker used to read coordinates for variability mapping of cutting width on ArcGIS application using the kriging method. The kriging result shows five different cutting width classes and the difference in variability in harvesting on the field. Keywords:   Sensor, Mini Combine Harvester, Accuracy, Cutting Width

Authors: Kuncoro Sapto , Suhandy Diding , Warji Warji , Ervandi Dicky
Published: December 2023

Honey with coffee flowers nectar is native honey formed from flower nectar. In this investigation, corn syrup and rice syrup, two artificial sweeteners, were utilized as an adulterant. Portable fluorescence spectroscopy and the SIMCA method are the tools and techniques employed. There were up to 20 samples of pure Apis mellifera honey and up to 120 samples of mixed honey (MC), each used twice. Data on the emission spectra, which are excited at a wavelength of 365 nm, were measured over the wavelength range of 300-800 nm. To improve accuracy, sensitivity, and specificity, the original spectral data was altered using a number of pre-treatments. Pretreatment with the original data with smoothing moving average may accurately identify samples and provides 100% accuracy, sensitivity, and specificity. One of the steps of the SIMCA approach, the cumulative PC, has a value of 92%, which indicates that it well explains the variation of the data. The x-loading plot's values are near the peak of the waves at 378 and 460 nm, indicating the existence of phenolic and flavonoid chemicals at those wavelengths. Keywords:   Apis mellifera honey, Corn syrup, Rice syrup, Portable Spectroscopy, SIMCA.

The problem of prevention of contamination of the residential area of metal mines by extracting metals from natural leaching solutions to reduce the incidence of residents is considered. Quantitative indicators are presented concerning the pollution of residential areas with natural leaching products. It is proposed to extract toxic metals from the liquid leaching products as they reach the earth surface. The mechanism of environmental degradation as a result of the activities of the enterprises of the Sadon lead-zinc plant is detailed. It is shown that the phenomenon of extraction of metals from natural and technological solutions can be used in the implementation of environmental protection processes. The results of the application of geotechnological methods of metal production in the North Caucasus are summarized. The contribution of scientists from the North Caucasus Mining and Metallurgical Institute to the theory and practice of metal leaching is noted. The program of technological and medical research was developed, and the results of comprehensive studies of the morbidity of mine workers and residents of residential areas depending on the distance from the source of pollution are presented. An algorithm for the organization of preventive leaching of ores left in the worked-out space is proposed. It is proved that the chemical impact of natural leaching of ore mining and processing products on the population of residential areas is the cause of technogenic metal-induced toxicity and is accompanied by an increase in diseases. It is substantiated that a radical measure to prevent progressive morbidity is the preventive extraction of metals from ore processing tailings and mine wastewater. It is shown that the extraction of metals from the products of their activities helps to reduce environmental damage and morbidity among employees of mining enterprises and the population of residential areas.

The article presents the main innovations of the TOXI+6 software platform for calculating the consequences of accidents involving hazardous substances and quantitative risk assessment in the field of industrial, fire and environmental safety and the main differences from the TOXI+Risk 5 PC. Plans are given for the future development of the platform, for conducting its beta -testing among users of TOXI+Risk 5 and licensing. Some of the most significant changes to the TOXI+6 platform in terms of performing calculations are: a general interface for working with plan objects; support for various types of equipment with hazardous substances; the ability to assess the possibility of destruction of objects and injury to people; in this case, the distribution of people can be specified considering the probability of presence in various places of the facility and with reference to the time of their presence in the vicinity of the hazardous facility during the 24-hour day and work week; an expanded list of types of dangerous accident outcomes and hazardous factors; the ability to take into account several options for one accident scenario; taking into account the impact of several hazardous factors on recipients within one scenario (or scenario option), a new system for outputting reporting materials. New capabilities of the TOXI+6 client-server platform will ensure the most complete automation of the stages of calculating the consequences of accidents and quantitative risk assessment; take into account the new provisions of methodological and regulatory documents of Rostechnadzor, EMERCOM of Russia, etc.; provide support for multi-threaded work for productive computing, cross-platform (compatibility with Linux-based operating systems), collaboration on projects, connection of modules with the required functionality, which will allow to reduce the labor intensity for conducting calculations, reduce the computer time of calculations and the conservatism of the resulting estimates.

The purpose of the work is to create a water-cooled rescuer anti-thermal suit to protect his body from ithe ncreased thermal effects during fire fighting, liquidation of burning gas and oil fountains, localization and liquidation of the consequences of emergencies at fire and explosion hazardous enterprises of the Russian Federation The research used an integrated approach based on the analysis of the results obtained by generations of authors of the Research Institute of Mining «Respirator» during the development of suits for the space, metallurgical and coal industries of the country. Based on the previously acquired experience in the development of heat protection suits, not only the external heat flows affecting the rescuer, but also the heat generated by the oxygen isolating respirator and the work performer were taken into account. In this case, the basic laws of thermodynamics, thermal conductivity and hydraulics were applied. The results obtained when determining the parameters of the anti-heat suit were confirmed empirically during testing of the product in a heat chamber and at the testing ground of the Research Institute of Geodynamics «Respirator». Fundamentally new anti-thermal suit with open-cycle water cooling was developed, which is confirmed by the received patent for a utility model. When determining the amount of water required to remove excess heat from the undersuit space, the heat released during air regeneration, as well as the heat absorbed by the R-30 parts and the radio station located in the undersuit space, were considered for the first time. To ensure safe working conditions in the suit at different temperatures, a water flow rate was established to ensure a decrease in the temperature of the environment in the space under the suit (about 4·10–3 m/min). Moreover, based on thermal sensations, the rescuer can himself regulate the flow of supplied refrigerant depending on the seasonal temperature fluctuations (for water supply in the range from 8 to 24 °C in February and August, respectively).
