Background: The number of elderly patients undergoing pacemaker (PM) implantation is constantly growing. However, information on survival and prognostic factors of this particular patient group is scarce. The objective of this study was to determine the survival of elderly and very elderly patients undergoing PM implantation, as well as to investigate prognostic factors of mortality.
Methods: This is a retrospective observational study of a single center. Patients ≥ 80 years of age, that underwent PM implantation between January 2017 and December 2018 in our center, were included for chart review. Very elderly patients were defined as those with ≥ 90 years of age.
Results: A total of 269 patients were included in the study with a mean age of 85 (±4.1) years. 53 patients were ≥ 90 years of age. 52% of the patients were male. 24.5% of the elderly patients and 41.5% of the very elderly patients received a single chamber PM. Median follow-up time was 28 (14-30) months, with no significant differences between the two groups of patients. The mortality rate for elderly patients was 15.7% for the elderly and 32.1% for the very elderly (p = 0.002). Generating multivariate Cox regression models, the following parameters showed to be significant predictors of all-cause mortality: Age (1.37 (1.02-1.29), p = 0.005), chronic kidney disease (5.57 (2.47-12.56), p<0.001), COPD (3.74 (1.19-11.55), p = 0.023) and cancer (3.57 (1.02-12.51), p = 0.046). In the group of the very elderly only age (1.58 (1.10-2.27), p = 0.014) and cancer (3.76 (2.38-4.18), p = 0.003) significantly predicted mortality.
Conclusion: Our study shows a good life expectancy of elderly and very elderly patients that underwent PM implantation, with a survival rate that is comparable to the general population. The primary prognostic factors were non-cardiological and comorbidities, such as chronic kidney disease, cancer and COPD, had a stronger association with mortality than age.

Published: March 2021

Acute abdominal pain secondary to intussusception is rare in adults and mainly caused by malignancy (70-90%), whereas in childhood intussusception’s etiology is mostly idiopathic (90% of cases). Gastrointestinal lipomas, especially in small bowel, represent an unusual cause of intussusception with complete intestinal obstruction or bleeding (acute or chronic) from mucosal ulceration. In acute settings, computed tomography (CT) should be confidently considered the gold standard for diagnosis. In adulthood, surgical management of acute symptomatic intussusception caused by lipoma is mandatory. We report a case of complete jejunal obstruction with intussusception due to 5 cm submucosal lipoma.
Laura Barney’s Discipleship to ‘Abdu’l-Bahá
Authors: Miron Layli Maria
Published: March 2021

The discipleship of the young American Laura Clifford Barney to ‘Abdu’l-Bahá in the early 1900s resulted in a flow of spiritual teachings from East to West. After several years of intense engagement with her teacher in Palestine, Barney sought to disseminate in her Western homelands what she had learned. Her private and public writings demonstrate how she employed ‘Abdu’l-Bahá’s teachings in her efforts to influence social discourse by promoting the Bahá’í Faith in Europe and the United States. Examining these teachings and Barney’s applications thereof in her rhetoric allows us to witness how a transnationalchannel of theological knowledge developed.
Thankful in Adversity
Authors: Dykema Lindsay-Rose
Published: March 2021

Mental health recovery has been conceptualized as a process through which individuals with severe mental illness improve their health and wellness, live a self-directed life, and work toward meaningful personal goals. While this is clearly an improvement over the traditional medical model of treatment of schizophrenia and related disorders, the spiritual dimension of mental health recovery still warrants closer investigation. The idea that adversity may offer spiritual insight and  opportunities for personal growth—a common theme in the teachings of the Bahá’í Faith—is particularly worthy of consideration. This paper reflects on how both the Bahá’í Writings and the literature on benefit finding can enhance the understanding and applications of mental health recovery principles.

Affecting millions, the rise of substance abuse, particularly opioids, has become a global health crisis, the leading cause of death and disability worldwide. Despite extensive scientific advances in understanding the complex biopsychosocial components of this phenomenon, there is no relief in sight. Yet, research studies during the past twenty years reveal an important role for spirituality and religion in prevention and recovery. The primary purpose of this article is to explore this role, examine various theories that have emerged about the positive influence of spirituality, and consider how an effective approach to prevention and treatment might be realized.
Augmented reality–mediated stereotactic navigation for execution of en bloc lumbar spondylectomy osteotomies
Authors: Molina Camilo A. , Dibble Christopher F. , Lo Sheng-fu Larry , Witham Timothy , Sciubba Daniel M.
Published: March 2021

En bloc spinal tumor resections are technically demanding procedures with high morbidity because of the conventionally large exposure area and aggressive resection goals. Stereotactic surgical navigation presents an opportunity to perform the smallest possible resection plan while still achieving an en bloc resection. Augmented reality (AR)–mediated spine surgery (ARMSS) via a mounted display with an integrated tracking camera is a novel FDA-approved technology for intraoperative “heads up” neuronavigation, with the proposed advantages of increased precision, workflow efficiency, and cost-effectiveness. As surgical experience and capability with this technology grow, the potential for more technically demanding surgical applications arises. Here, the authors describe the use of ARMSS for guidance in a unique osteotomy execution to achieve an en bloc wide marginal resection of an L1 chordoma through a posterior-only approach while avoiding a tumor capsule breach. A technique is described to simultaneously visualize the navigational guidance provided by the contralateral surgeon’s tracked pointer and the progress of the BoneScalpel aligned in parallel with the tracked instrument, providing maximum precision and safety. The procedure was completed by reconstruction performed with a quad-rod and cabled fibular strut allograft construct, and the patient did well postoperatively. Finally, the authors review the technical aspects of the approach, as well as the applications and limitations of this new technology.

Published: March 2021

In recent years, the optimal design of the workshop schedule has received much attention with the increased competition in the business environment. As a strategic issue, designing a workshop schedule affects other decisions in the production chain. The purpose of this thesis is to design a three-objective mathematical model, with the objectives of minimizing work completion time, work delay time and energy consumption, considering the importance of businesses attention to reduce energy consumption in recent years. The developed model has been solved using exact solution methods of Weighted Sum (WS) and Epsilon Constraint (Ɛ) in small dimensions using GAMS software. These problems were also solved in large-scale problems with NSGA-II and SFLA meta-heuristic algorithms using MATLAB software in single-objective and multi-objective mode due to the NP-Hard nature of this group of large and real dimensional problems. The standard BRdata set of problems were used to investigate the algorithms performance in solving these problems so that it is possible to compare the algorithms performance of this research with the results of the algorithms used by other researchers. The obtained results show the relatively appropriate performance of these algorithms in solving these problems and also the much better and more optimal performance of the NSGA-II algorithm compared to the performance of the SFLA algorithm.

Authors: Pecorella Irene , Okello Tom Richard , Okwang Martin David
Published: March 2021

BACKGROUND: Little information is available on male breast cancer (MBC) incidence from sub-Saharan Africa. OBJECTIVE: This is a retrospective study on MBC in rural North Uganda, based on the pathology records of a private, non-profit, missionary hospital. METHODS: All male patients that had histological diagnosis of breast carcinoma from January 2009 to December 2016 were included in this study. RESULTS: In time span of 8 years, there were 337 consecutive breast cancer presentations, including 21 MBC (6.2%). The latter patients showed advanced disease (mean symptom duration: 20.3 months; mean tumour size: 5 cm) skin ulceration and ipsilateral lymph node metastasis: 60%). The mean age was 60.52 years (from 30 to 85 yrs). Ductal infiltrating carcinoma was the prevalent histological type in our series (65%), followed by an unusually high rate of papillary carcinomas (15%). There appeared to be a prevalence for left breasts (11 LT versus 6 RT; 64.7%), a finding also observed in the majority of MBC. CONCLUSIONS: This study is representative of the scenario in Northern Uganda, where MBC accounts for 6.2% of breast cancers, More information on the occurrence and risk factors of this unusual neoplasm in African countries may prompt prevention of chronic liver disease and early recognition and treatment of MBC.

Published: March 2021

BACKGROUND: The acute vascular disease deep vein thrombosis (DVT) requires oral anticoagulants to prevent progression. Monitoring therapeutic efficacy of direct oral anticoagulants (DOAC), including rivaroxaban, is problematic as no reliable test is available. Advances in rheometry have led to the development of a functional coagulation biomarker using Gel Point (GP) analysis which assesses clot structure formation. The biomarker measures incipient clot formation time (TGP) and quantifies fibrin clot structure in terms of fractal dimension (df). OBJECTIVE: This study aimed to investigate clot structure formation in first time DVT and the effect of rivaroxaban treatment. METHODS: This prospective observational cohort study measured the GP and standard laboratory markers at three sample points: pre-treatment and at 20 and 60 days following 15 mg BD and 20 mg OD rivaroxaban respectively. RESULTS: Forty DVT patients (mean age 64 years [SD±14.8]; 23 males, 17 female) were recruited. The results show that DVT vs non-DVT patients did not have a significantly different GP profile (df: 1.72±0.06 vs 1.70±0.06 and TGP: 267±68 sec vs 262±73 sec) with both within the defined healthy index. In addition, rivaroxaban therapy increased TGP to 392 s (±135 s) after 20 days, and subsequently increased to 395 s (±194 s) at 60 days but did not significantly increase df (from 1.69±0.05 to 1.71±0.06). CONCLUSIONS: The results indicate in this cohort of DVT patients there was no underlying hypercoagulable effect as determined by gel point analysis. Furthermore, the anticoagulant effect of rivaroxaban prolonged clotting, suggesting a protective effect against clot formation, without significantly reducing clot microstructural properties.
Whale optimization based synchronization and control of two identical fractional order financial chaotic systems
Authors: Gupta Sangeeta , Varshney Pragya , Srivastava Smriti
Published: March 2021

This paper proposes a scheme to synchronize fractional order chaotic systems employing fractional PID controller. The parameters of FOPID are tuned using Swarm based optimization techniques, viz.: Whale optimization algorithm and Particle swarm optimization techniques. To assert the complete synchronization, master-slave method has been implemented. Chaotic systems are highly dependent upon initial conditions and parameter perturbations. Therefore, taking these properties into consideration, synchronization of two identical fractional order financial chaotic systems is performed with distinct initial conditions. To show the efficacy of the proposed method, analysis is performed for orders between 0 to 1, and also for sensitivity to initial conditions.
THE IMPROVEMENT AND REALIZATION OF FINITE-DIFFERENCE LATTICE BOLTZMANN METHOD

Published: March 2021

The Lattice Boltzmann Method (LBM) is a numerical method developed in recent decades. It has the characteristics of high parallel efficiency and simple boundary processing. The basic idea is to construct a simplified dynamic model so that the macroscopic behavior of the model is the same as the macroscopic equation. From the perspective of micro-dynamics, LBM treats macro-physical quantities as micro-quantities to obtain results by statistical averaging. The Finite-difference LBM (FDLBM) is a new numerical method developed based on LBM. The first finite-difference LBE (FDLBE) was perhaps due to Tamura and Akinori and was examined by Cao et al. in more detail. Finite-difference LBM was further extended to curvilinear coordinates with nonuniform grids by Mei and Shyy. By improving the FDLBE proposed by Mei and Shyy, a new finite difference LBM is obtained in the paper. In the model, the collision term is treated implicitly, just as done in the Mei-Shyy model. However, by introducing another distribution function based on the earlier distribution function， the implicitness of the discrete scheme is eliminated, and a simple explicit scheme is finally obtained, such as the standard LBE. Furthermore, this trick for the FDLBE can also be easily used to develop more efficient FVLBE and FELBE schemes. To verify the correctness and feasibility of this improved FDLBM model, which is used to calculate the square cavity model, and the calculated results are compared with the data of the classic square cavity model. The comparison result includes two items: the velocity on the centerline of the square cavity and the position of the vortex center in the square cavity. The simulation results of FDLBM are very consistent with the data in the literature. When Re=400, the velocity profiles of u and v on the centerline of the square cavity are consistent with the data results in Ghia's paper, and the vortex center position in the square cavity is also almost the same as the data results in Ghia's paper. Therefore, the verification of FDLBM is successful and FDLBM is feasible. This improved method can also serve as a reference for subsequent research.

Honeycomb is described by orthotropic homogeneous media. The mechanical properties of the media are described by the simulation of the stress state honeycomb in commercial software ANSYS. The classical hexagonal honeycomb is analyzed numerically. The other types of the honeycomb are not considered in this paper. The media, which is obtained as a result of homogenization, has orthotropic mechanical properties. The honeycomb is produced from polycarbonate, which is orthotropic material. The suggested approach can be applied to other materials, which are used for 3D printing. The mechanical properties of this honeycomb material are determined experimentally for specimens, which are produced by FDM manufacturing. The matrix of the Hooke law is obtained in the result of six finite element calculations of the cell part of the honeycomb. To determine the different elements of this matrix, the cell part of the honeycomb undergoes different boundary conditions and different stressing. The fourth part of one cell is considered to calculate honeycomb mechanical properties. The software ANSYS is used to calculate the fourth part of the cell. The area near the cell part is filled up to cube using elastic air. The elastic air is isotropic material with a small Young modulus. The cube sides undergo constant displacements to perform numerical analysis. Such different displacements are equal to six. As a result of the numerical simulations, the elements of the stress tensor are determined by the stress averaging on the volume of the finite element. As a result of calculations, the set of nine engineering constants of orthotropic homogeneous media is obtained. Analysis of the convergence of the numerical simulation results is carried out for numerical simulations of the stress state by the concentration of the finite element mesh. As follows from the convergence analysis, 1745481 3D finite elements are enough for the discretization of the cube area.

The paper shows and analyzes circuit solutions for improving the existing schemes of ejector heat-using refrigeration machines, which are used as part of cogeneration plants. One of the promising areas is the use of an aerothermopressor, which implements the effect of thermogasdynamic compression, which is to increase the pressure while reducing the temperature in the evaporation of liquid, which injected into the flow of vapor moving at speed near the sound. To analyze the efficiency of ejector refrigeration machines, the developed calculation model was used, which takes into account the use of an aerothermopressor in the cycles of refrigeration machines with the features of the calculations of cycles and circuits. To select and determine possible circuit solutions, the efficiency of an aerothermopressor for different refrigerants was evaluated and a comparative analysis of the characteristic parameters of the efficiency of an aerothermopressor in the range of cooling temperature differences is 20–100 oC was made. It is possible to increase the efficiency of ejector heat-using refrigeration machines when using an aerothermopressor by providing a temperature difference of 60–100 oC. The analysis showed that the most important are: R717, R134a, R227ea, R1234ze (E), R1234yf (2–4%). It is possible to provide a higher thermal coefficient for ejector heat-using refrigeration machines by using an aerothermopressor in the circuit using the circulation of liquid refrigerant. The corresponding increase in the thermal coefficient is 1.5–2.0%. The use of an aerothermopressor in the scheme with heat recovery allows removing additional overheating of vapor before suctioning into the ejector with a corresponding increase in the thermal coefficient by 4-8%. The analysis shows that the total increase in the thermal coefficient due to the combined use of an aerothermopressor, heat recovery, and recirculation is 10–15% at a base value of 0.30–0.40.

The influence of skew axes of the connecting shafts of marine aggregates on the efficiency and reliability of ship power plants is investigated. The reasons for the occurrence of centerings of axes of connecting shafts of marine aggregates are considered and their classification is offered. Failures of ship power plants are classified according to their impact on the efficiency of the installation (according to the consequences), according to the methods of their elimination, and by their nature and are divided into the groups according to the classes. It is shown that during operation, in the conditions of axial skew, traditional designs of the toothed clutch are characterized by non-uniform distribution of forces between pair of gears, which leads to their overload and, as a consequence, reduced load capacity, increased contact stresses, deterioration of lubrication surfaces of gears, increase in power consumption for friction, reduction of efficiency and deterioration of vibroacoustic characteristics due to shock load of gear. Ways to increase the efficiency of ship power plants by providing parameters of reliability of the main power plants by eliminating the negative impact of the centering axes of the connecting shafts of marine aggregates through the use of compensating devices are considered. It is proposed to use as compensating devices, the design of high-efficiency clutch, which in the conditions of axial skew, are characterized by a more uniform distribution of forces between pair of gears than existing ones, ie work almost as a perfect hinge. Regarding the proposed toothed couplings, a previously unknown objectively existing property of the toothed clutch operating at the skew of the axes of the connecting shafts is established, which is that under a certain nonlinear law changes in the generating side surfaces of the outer teeth evenly between all conjugate pairs of teeth. The use of a high-efficiency clutch in the ship power plants is considered and the basic and functional (structural) scheme of the main marine aggregate with a series connection of elements is made to assess the impact on reliability parameters.

Published: March 2021

The production of carbapenem enzyme is one of the most frequent mechanisms reported in cabapenem resistant Pseudomonas aeruginosa. Besides, a growing number of mobile colistin resistance (MCR) genes are threatening the renewed interest of colistin as a "last-resort" against carbapenem-resistant pathogens. Therefore, the detection of carbapenem-resistant and colistin-resistant phenotypes as well as preventing transmission of multi-resistant P. aeruginosa strains with genes coding for carbapenemase is extremely necessary.

Among 159 P. aeruginosa strains were collected 46 isolates, which is resistant or intermediated to meropenem. Modified carbapenem inactivation (mCIM) and colistin broth disk elution (CBDE) methods were used to identify carbapenemase-producing strains and colistin resistance. In addition, a multiplex real-time PCR technique was applied to investigate the frequency of emergence of carbapenem resistance genes.

The results revealed that 25 strains (54.3%) were positive with mCIM test and none of them resistant to colistin by CBDE method. Number of strains carrying a gene blaIMP: 4 strains (16%), blaNDM: 2 strains (8%). Strains are carrying two genes: blaIMP + blaNDM: 10 strains (40%), blaVIM + blaNDM: 1 strain (4%), blaNDM + blaOXA-48: 1 strain (4%) and are carrying three genes blaIMP + blaNDM + blaOXA-48: 6 strains (24%), blaKPC + blaIMP + blaNDM: 1 strain (4%).

All mCIM positive P. aeruginosa were contained carbapenemase genes. Colistin still reserved a good effect to combine with other antibiotics in multi-resistant treatment. Hence, the classification of genes can help clinicians selected appropriate antibiotics so that more effective treatment for patients.

The COVID-19 pandemic reminded society that, in addition to natural disasters, epidemics are also part of our past, present and future. Even if we cannot prevent the emergence of dangerous viruses, we must be prepared to mitigate their impact on society. It is clear that the COVID-19 epidemic, in addition to its severe physiological effects, has caused significant economic damage worldwide. Global supply chains in different industries face significant challenges. Not only is the economy affected by the virus; society as a whole is affected, leading to dramatic changes in the behaviour of businesses and consumers. The global supply chains that have shown a high level of stability and resilience in recent decades now face a number of disruptive factors. The pandemic adversely affected the entire chain in terms of both manufacturing and logistics processes, as well as a significant shift in demand. The pandemic highlighted the need to focus on three key areas to increase the resilience of supply chains: risk and flexibility, global transparency, and rapid response and decision-making. It can be concluded that the changes caused by the epidemic will make global supply chains shorter and more transparent through renewed strategies such as digitization, the tools of which are the building blocks of the DSN.

The 2019 coronavirus pandemic (Covid-19) had a broad influence on the economy in Indonesia. One of them was a little entrepreneur. Government regulation to maintain distance and decrease public places and characters from the swift spread of coronavirus caused many stores or businesses to close or greatly decrease the number of buyers or even no buyers. This condition certainly negatively affected little entrepreneurs, which could cause a decrease in immunity. One of the efforts to overcome was through giving Al Qur’an counseling and activity practice in daily life where was expected more increase the strength of the entrepreneur’s spirit and could face life in covid-19 and next.

Proses pemerolehan bahasa setiap anak tidaklah seragam. Hal ini terlihat ada anak yang sangat aktif berbicara yang memiliki banyak pembendaharaan kata dan sebaliknya juga ada anak yang masih pasif pada usia tertentu yang mengakibatkan kurangnya kosakata yang diucapkan oleh anak. Salah satu akuisisi atau pemerolehan bahasa pada anak adalah sintaksis. Metode penelitian yang digunakan dalam penelitian ini adalah pendekatan kualitatif deskriptif. Penelitian ini mendeskripsikan data yang dikumpulkan berupa pemerolehan sintaksis yang dibagi menjadi dua tahap, yaitu dua kata dan tiga kata atau lebih. Data penelitian ini adalah kalimat yang diucapkan oleh Zahra yang berusia 2 tahun. Dalam pengumpulan data, peneliti menggunakan teknik rekam dan catat. Berdasarkan penelitian ini dapat disimpulkan bahwa kalimat yang paling banyak ditemukan adalah kalimat imperatif dibandingkan kalimat deklaratif maupun interogatif. Kalimat imperatif yang diucapkan oleh Zahra mengisyaratkan bahwa anak pada usia ini lebih banyak meminta kepada orang di sekitarnya. Kalimat imperatif yang dituturkan jenisnya beragam. Hal ini terlihat pada makna kalimat yang diucapkan berdasarkan konteksnya. Kalimat imperatif yang diucapkan bersifat meminta, mengajak dan memohon secara halus. Hal ini ditandai dengan penggunaan kata mau, ayo, tolong dan menyuruh secara langsung.

This study aims to reveal the relationship between Islamic philosophy and Islamic economic philosophy, both in terms of foundation, operation, and objectives. This library research (Library Research) uses documentation data collection techniques with data analysis, namely content analysis. The results showed that the relationship between sharia philosophy and sharia economic philosophy is that there is a philosophical foundation based on al-qur'am, hadith, ijma 'and qiyas, as well as operational principles, observations are made, take generalization conclusions and serve as theory, while the goal is both want to get happiness in the world and the hereafter, but what distinguishes the two lies in the broader study of sharia philosophy and complexity, while Islamic economic philosophy specializes in sharia economic studies. But for sharia economic philosophy discusses tauhid, caliphate, tazkiyah, and masuliyya. Operational principles, observing, drawing conclusions and making theory. The goal of obtaining falah, namely survival, freedom of desire, and strength and honor.

Published: March 2021

Purpose. To establish analytical dependences for calculating the characteristics of the ash suspension and the velocity of constrained settling of coal and quartz depending on the particle size and density of the medium, which is necessary for calculating the design and determining the operating modes of hydraulic devices for extracting coal from water mineral suspension of fly ash from thermal power plants. Methodology. The research was carried out on the basis of a cellular suspension model and classical concepts of constrained particle motion in laminar and turbulent flow. For analytical evaluation of the characteristics of the suspension, the defining correlations and the Wend formula for viscosity were used. The Ergun equation and correlation analysis methods were used to calculate and analyze the speed of constrained movement of ash suspension particles. Findings. Approximating nonlinear functions are obtained for determining the speed of constrained movement of coal and quartz particle size up to 4 mm in an ash suspension with a density of 1.31.8 g/cm3. It is shown that, for both settling and ascending of coal, there is a direct relationship between the velocity and particle size, in both cases it is nonlinear. For any coal size, the speed of ascent depending on the suspension density is of extreme nature; the rational density range is 1.551.8 g/cm3 with a maximum of 1.65 g/cm3. The established dependencies allow us to determine the size of coal and quartz particles, taking into account the counter-flow of the liquid phase, as well as the boundary size. Originality. For the regime of weak-turbulence flows there were established dependences and approximation equations of the constrained movement speed of coal and quartz particles the main components of the water suspension of fly ash from the Novo-Kramatorska TPP, depending on the size and density of the ash suspensions with changes in the characteristics of the medium depending on density. The frames of the Stokes description of processes are established. It is shown that the movement of the liquid phase in a counter-flow with precipitating particles is effective for surfacing of thin coal classes. Practical value. The described approach can be used for analytical evaluation of the characteristics and velocity of constrained movement in various water suspensions of discrete solid particles in weak-turbulence flows. The advantage is a wider coverage of hydraulic equipment operating modes. The results obtained are necessary for designing and determining the technological modes of operation of various hydraulic devices in the technology of complex processing of fly ash from TPPs.

Purpose. Characteristics of heat transfer processes in multilayer bodies of basic geometric shapes simultaneously under conditions of convective heat transfer on its surfaces and taking into account imperfect thermal contact between the layers. Methodology. A direct method was applied to solve a one-parameter family of boundary value problems in the theory of heat conduction. This method is based on the reduction method, the concept of quasiderivatives, a system of differential equations with impulse action, the method of separation of variables, and the modified method of eigenfunctions of Fourier. It is worth noting that the application of the concept of quasiderivatives allows you to circumvent the well-known problem of multiplication of generalized functions, which arises when using the differentiation procedure of the coefficients of a differential equation. Such a procedure, in our opinion, casts doubt on the equivalence of the transition to the differential equation obtained in this way with generalized coefficients. Findings. The solution to the problem is obtained in a closed form. The proposed algorithm does not contain a solution to volume conjugation problems. It includes only: a) finding the roots of the corresponding characteristic equations; b) the multiplication of a finite number of known (2 2) matrices; c) the calculation of certain integrals; d) summing the required number of members of the series to obtain the specified accuracy. As an illustration, we consider model examples of heating eight-layer structures in a fire. Originality. For the first time, the direct method has been applied to solving the problem of the distribution of an unsteady temperature field over the thickness of multilayer structures of basic geometric shapes simultaneously, in the presence of imperfect thermal contact between the layers. Practical value. The implementation of the research results allows us to effectively study the heat transfer processes in multilayer structures, which are found in a number of applied problems.
Shallow tunnel face stability analysis using finite elements

Published: March 2021

Purpose. This work aims to study the tunnel face stability (Algiers subway Tunnel) and evaluate common numerical procedures that are used for analyzing the tunnel face stability. Two-dimensional (2D) and three-dimensional (3D) Finite Element (FE) modeling using PLAXIS programs. Methodology. Tunneling is executed by the NATM method; two types of calculations are used. The first one is done by reducing the applied face pressure until the face is collapsed. The second calculation method involves the Phi-c (the angle of internal friction and bonding) reduction method, which is based on calculating the safety factor of the shear strength of the soil. Both methods are applied for 2D and 3D FE-modelling. Findings. It is found that determining the applied face pressure is an important consideration to avoid face failure or excessive deformations with numerical methods resulting in more precise findings than analytical methods. Originality. The originality of this work is the use of both 2D and 3D modelling, combined with two approaches: structural analysis of plastic state and Phi-c reduction method based on calculating the safety factor of the shear strength of the soil. Practical value. This study illustrates that the reducing shear strength method is much better than the reducing applied face pressure method. Moreover, the result of 3D FE-modelling gives a better prediction comparing with the 2D FE-modelling results.
