Algorithm, implementation, data preparation, calculation of statics and dynamics of beam lattice structures in SSKA KIDYM
Authors: Andrieiev Yuriy , Marusenko Oleksii
Published: January 2023

The problem of developing a universal analytical description and an algorithm for automatic computer calculations of dynamics, statics and kinetostatics of mechanical models of structures, which include beam lattices, is considered. These can be calculations of transient processes, steady-state free and forced vibrations, determination of equilibrium positions and stress-strain state under static and dynamic loads, etc. The structure itself can be flat or spatial, fixed or movable on a plane or in space. Various equipment can be attached to it. It is shown how it is possible to analytically describe a part of the structure, which is a beam lattice, in a language for preparing computer data of a special computer algebra system KiDyM (SCAS KiDyM). Based on the theory of elasticity of Bernoulli-Euler beams, 2 forms of the canonical representation of the potential energy of an elastic beam are obtained. This allows us to introduce a new element into the accepted language for describing mechanical models - a “Beam”, for which the positions of coordinate systems associated with its extreme sections, its geometric and physical parameters are indicated. The position of these sections is determined by the lattice nodes, as by solid bodies. Thus, the generalized coordinates of the mechanical model are determined. An algorithm for the formation of elements of mechanical models of SCAS KiDyM has been developed. This gives the elastic structure of the mechanical model. The tools available in this program automatically build the equations of dynamics and statics, i.e. form a mathematical model, according to which dynamic and static calculations are carried out. The article demonstrates the proposed method in detail on the example of calculating the deformation of a window frame. A comparison of the results with calculations based on an independent program was made.

Key words: lattice beam structures, Bernoulli-Euler beams, a special system of computer algebra, calculations of the dynamics of spatial mechanical models.
Computational approach to thermal-stressed state modeling of tire based on the algorithm of its self-heating analysis . Part 1 – Theoretical basics of the approach
Authors: Viazovychenko Yuliia , Larin Oleksiy
Published: January 2023

Elastomers and their composites are widely used in modern innovative technology: for the production of aviation and automobile tires, anti-vibration elements (rubber, rubber-metal springs), dampers, elastomeric bearings. Also they are used in shaft suspensions, as spacers between structural parts, supporting parts and fasteners. Elastomeric elements of structures have a high dynamic load, in particular of a cyclic nature, which is accompanied by the formation of hysteresis loops and, as a result, the occurrence of the phenomenon of self-heating. An increase in temperature in the middle of materials causes significant changes in their mechanical properties, reduces strength characteristics, accelerates aging and degradation processes, and has a significant impact on fatigue processes. In addition, an increase in temperature causes an additional thermal stress state, capable of significantly changing the qualitative picture of the structure's deformation characteristics' distribution. Thus, the purpose of this study is development of approach to assessing the thermal stress state of structures made of elastomeric materials for the possibility of further analysis of its influence on the structure work as a whole. The appropriate approach was built on the basis of numerical modeling of thermal and deformation processes which takes place into the structure during operation. The proposed approach includes several related calculations by using FEM and is based on the fundamental approaches of the theories of elasticity and viscoelasticity, thermal conductivity and thermo-elasticity. Thus, the article presents an approach to the analysis of the thermal stress state of structural elements under operating conditions. This approach was applied to determine the thermo-strain-stress characteristics of a pneumatic tire and corresponding pictures of its distribution were obtained.

Educators as a type of profession are also required to have a certification of expertise. It is stated in Permendikbud No. 16 of 2007 that one of the competencies that must be possessed by an educator is proficiency in using information technology in the teaching and education process. The TPACK method is one method that is considered capable of boosting the competence of educators. The TPACK method can be optimally implemented if it is supported by good learning system management. Therefore, it is necessary to integrate the TPACK learning method with the learning management system. This study aims to describe the planning and design of the integration of the TPACK learning method into the management of the education system in Indonesia as an effort to increase the competitiveness of the workforce, especially workers in the education sector. The research method used is descriptive qualitative method with a literature study approach. The data used is secondary data derived from scientific publications. The results show that the core components of the TPACK method consist of technology, pedagogy, and content. These three components can intersect and synergize so as to create new conditions of understanding. TPACK requires educators to have a complete understanding related to technology operations and the use of technology in learning, demands to continue to develop pedagogical abilities, and increase educator competencies through increasing literacy and understanding of the field of study to be taught.

Published: January 2023

Acute pancreatitis is responsible of considerable amount of hospital admissions, and therefore, significant morbidity and mortality in the modern world. The disease poses a significant burden to healthcare systems since its incidence have been rose to as high as 45 subjects in every 100000 population since early 1990s. Excessive alcohol consumption and biliary tract disorders are two most common causes of acute pancreatitis. Other etiological factors include dyslipidemia, surgery or traumatic injury of abdomen, hypercalcemia, infections, inflammation related to vasculitis, tumors of pancreas or ampulla and various drugs. Drugs that cause acute pancreatitis are anti-neoplastic agents (i.e., asparaginase, azathioprine, mercaptopurine), antibiotics (i.e., tetracycline, isoniazid, sulfonamides, metronidazole), anti-inflammatory drugs (i.e., celecoxib, meselamine, leflunomide), thiazide diuretics, anti-diabetic treatments (i.e., exenatide, sitagliptin), and anti-hypertensive and anti-hyperlipidemia therapies (methyl dopa, enalapril, fenofibrate, simvastatin). Medical interventions such as enteroscopy, peritoneal dialysis, endoscopic retrograde colangio-pancreatography, may also induce acute pancreatitis. Cystic fibrosis and pancreas divisum are also contributing conditions to acute pancreatitis.

Objective: The categorization of sweat gland tumors has been inconsistent over time. These tumors, having varying potential for malignancy, may behave as indolent neoplasms while others can be highly metastatic. The characteristics of most of these tumors are overlapping and the information of distinctive findings about these neoplasms is imperative. Traditionally, sweat gland tumors were classified as eccrine and apocrine only but recently, this has been found that several sweat gland tumors may exhibit eccrine and apocrine types both. Some tumors exhibit further complex features due to the existence of other differential appearances. This can be in the instance of apocrine neoplasms because of the close embryological link between apocrine glands, hair follicles and sebaceous glands and they can be classified as follicular and/or sebaceous tumors. Cutaneous adnexal neoplasms are a diagnostic challenge, especially for tumors with sweat gland differentiation, due to a huge number of uncommon entities, designation of different terms to the identical tumor following to disagreement about the taxonomy and nomenclature of such tumors. This review article provides updated information about various cancerous sweat gland neoplasms with emphasis on recent conclusions for the diagnosis and generalized therapy of such neoplasms.

Authors: Wang Ruqi
Published: January 2023

Using the panel data of 284 cities from 2011 to 2020 in China, this research statistically tests the direct impact and internal mechanism of digital finance on urban haze governance. The results show that: (1) The development of digital finance can significantly inhibit the concentration of urban haze, and a stronger inhibitory effect in areas where the government pays more emphasis to haze governance and in cities with high level; (2) After mechanism inspection, it is found that digital finance can indirectly promote urban haze governance by influencing green innovation, cooperative innovation, industrial structure upgrading and producer services agglomeration; (3) The results of spatial econometric analysis show that digital finance can suppress the haze concentration in the region, and simultaneously inhibit the neighboring areas through spillover effects; (4) Further inspection shows that the spatial spillover effect of digital finance on haze governance has an obvious spatial attenuation feature, demonstrating that a dense area of spatial spillover is within 310 km. The spillover effect gradually disappears when the threshold is exceeded.
A model for predicting large energy microseismic events in coal mines based on system sample entropy
Authors: Jin Peijian , Lu Xin , Yan Weilong , Ge Suling
Published: January 2023

For the prediction of large energy microseismic events(LEME) in mines, it is often necessary to study its spatial distribution law, precursor information and microseismic activity law, and then establish prediction methods and models by analyzing physical indicators such as microseismic energy and frequency variation characteristics of mine working face. The traditional methods have the characteristics of relying on the physical index of a certain working face, with large limitations and small universality. In this paper, the prediction model of LEME is constructed by combining physical indicators and spatio-temporal data. We introduce system sample entropy to measure the complexity of the whole system. Pearson correlation coefficient shows that the system sample entropy sequence is always positively correlated with the microseismic energy sequence. Therefore, the prediction model based on system sample entropy is feasible. After several optimizations of the model, the LEME with energy greater than 105J in the prediction area can be accurately predicted. Experiments show that our optimization model can predict the LEME in the predicted area well and has high accuracy. At the same time, this model has certain reference value for other similar complex space-time systems.

Published: January 2023

The primary goal of wireless sensor networks from a design point of view is to enhance the network's lifetime. Among the different options for reducing operational energy consumption, energy invested in routing and cluster head selection is considered to be very effective mechanisms. Both tasks have been considered as very challenging and difficult to obtain the efficient solution. Since it is difficult for traditional approaches to satisfy the requirements and difficulties, a heuristic solution focused on natural computation methods has provided a lot of naivety. The proposed work efforts to address these challenges using computational intelligence especially differential evolution and genetic algorithm. An energy efficient route discovery for dynamic network is designed with variations in DE, quick and adaptable routes were discovered for networks undergoing changes. A knowledge based DE has been designed depending on prior knowldge to redefine new routes for changing network. A hybrid mutation strategy under standard DE is designed for cluster head selection providing faster convergence characteristics. The proposed solutions were implemented under MATlab environment and the results have shown that the proposed solutions are performing better for different network configurations. Dynamic route discovery using KDE has achieved energy saving of 9.83 to 49.2 percentage as compared to RDE and 6.7 to 29.5 percentage as compared to PDE. Also energy saving attained in cluster head selection using proposed HMDE is 10 to 33 percentage better compared to dyPSO and 5 to 10 percentage better compared to SDE.
Triple-band metamaterial perfect absorber for refractive index sensing in THz frequency
Authors: Khodadadi Bahare , Babaeinik Majid , Ghods Vahid , Rezaei Pejman
Published: January 2023

A triple-band metamaterial perfect absorber (MPA) is founded of monolayer graphene in THz region which is adjustable and polarization-independent is presented. The first layer of the structure from top contains of a graphene ring at the center of structure with four graphene wheel-shaped around it and four graphene triangles in the corner. This proposed structure has caused us to achieve 98.64%, 99.97% and 99.98% perfect absorptions peaks at 8.17 THz, 9.74 THz and 11.95 THz, respectively. We can vary the absorption peak frequencies to our desirable frequencies by changing the Fermi level of graphene. By tunining the incident angle waves up to 60 degrees, the frequency peaks and the value of absorption change slightly. Moreover, very significant matter about suggested absorber structure design is that it is polarization independent so by tuning the polarization angle, the frequency peaks and the value of absorption remain unchanged. These aspects make the suggested absorber proper for applications such as imaging, detecting, filtering and sensing. We have investigated the application of the MPA in the sensing of refractive index. The refractive index of the unknown material can be measured through shifts of frequency peaks. Based on the obtained results, it seems that the metamaterial perfect absorber is a good candidate for biosensors application.

Social and network interaction on the Internet: to the definition of the media phenomenon
Authors: Zotov V. V. , Vasilyeva I. N. , Krivoukhov A. A.
Published: January 2023

The large-scale introduction of computers into professional and everyday human activities, the formation of a global mass communication system based on the Internet and the formation of a single network space formed the basis of a modern social communication system. But at the same time, despite the long period of their development, there was no unambiguous concept denoting the phenomenon of Internet-based media, which includes means of communication, as well as the social-network interaction environment formed by them. The authors analyze four concepts used to display the media phenomenon: (1) information and communication environment, (2) social network space, (3) media space and (4) public communication space. Analysis shows that each of these concepts focuses on a specific aspect of the communications of modern society. The information and communication environment is a semi-structured set of computers and information and telecommunication technologies that allow organizing actor interactions to coordinate their activities in the storage, transmission, processing of information. A social network space is rhizome from social media, which allows users to organize online communication and produce user-generated content. Media space is a complex configuration of social media related to the production and consumption of media, the unity of which, within the framework of the information picture of the world, holds a certain social space together. The public communications space is a set of social media aimed at mainstreaming socially significant problems and discussing in the social-network space.
Generalized brands as a mechanism of cultural transmission in everyday communications practices
Authors: Vydrina A. S.
Published: January 2023

The article considers the process and result of the specific transition of phenomena, commercial in origin and functions, into a socio-cultural non-commercial space with their subsequent transforma tion into mechanisms of cultural transmission. In this review, they are conditionally designated as “generalized brands”. The author made an attempt to identify the main positive and negative features of the process of the emergence of such a brand in the company and in the society. The article also provides the concept of habitus of Pierre Bourdieu as a theoretical basis for analyzing the formation and development of generalized brands. The process of brand generalization can, according to the author, become the subject of sociological research, since such brands form new social actions, behavioral models in society. Perhaps “habitus” will hel p to resolve questions about the causes of generalization, its consequences for society in order to understand the impact of processes, the implementation of their intra-economic fields, on processes, implementation in other social fields. Based on the results of the first stage of empirical research, the author puts forward some hypotheses and draws the first conclusions about the specifics of this transition, in particular, about the peculiarities of filling the habitus of a modern individual with non-commercial versions of these phenomena.

Published: January 2023

In low- and middle-income countries, ensuring water, sanitation, and hygiene (WASH) facilities for households remains a major public health concern. Therefore, this study aimed to assess households’ access to WASH services and associated factors in Ethiopia. A cross-sectional study was conducted among 16,650 and 8,663 households in the 2016 Ethiopian Demographic Health Survey (EDHS) and 2019 Mini-EDHS, respectively. The households were selected using a stratified two-stage cluster sampling technique. Multivariable logistic regression analysis was performed to identify factors associated with basic WASH services. Households’ access to basic water services was 65.2% (95% CI: 64.5–65.9%) and 68.7% (95% CI: 68.01–69.4%) in the 2016 EDHS and 2019 Mini-EDHS, respectively. Only 25.9% (95% CI: 25.2–26.62%) in the 2016 EDHS and 27.5% (95% CI: 26.34–28.3%) in the 2019 Mini-EDHS households had access to basic sanitation services. Moreover, only 38% (95% CI: 37.25–38.8%) of households had access to basic hygiene services in the 2016 EDHS. Female-headed households, urban residents, having education, family members ≥7, presence of soaps or detergents, and having a better wealth index were the most likely to have access to basic WASH services. The findings in general suggest the need for effective WASH interventions.

Karanjin (1) is a natural furanoflavonol derivative isolated from seeds of Pongamia pinnata
(L.) Pierre. In this paper, we have accomplished a concise total synthesis of karanjin (1) as well as its
natural analogues pongapinnol D (2), 3-hydroxy-6-methoxy-2-phenyl-4H-furo[2,3-h]-1-benzopyran-
4-one (3) and 3,6-dimethoxy-2-phenyl-4H-furo[2,3-h]chromen-4-one (4). One-pot aerobic oxidation
was the key step to afford the flavonol framework under mild conditions. The anti-inflammatory
properties of synthesized 1–4 were determined against NO production in the LPS-stimulated
RAW264.7 cells.

Objective:

We assessed the feasibility of spectral CT imaging for diagnosing lung adenocarcinomas manifesting as ground-glass nodules (GGNs) with varying Ki-67 expression.

Methods:

Spectral CT parameters in 116 patients with lung adenocarcinomas manifesting as GGNs were analyzed. Cases were grouped into pre-invasive/minimally invasive adenocarcinoma (pre/MIA) and invasive adenocarcinoma (IA) groups. The Ki-67 labeling index (Ki-67 LI) was measured and compared between the two groups. Ki-67 LI was divided into three grades based on the number of positive-stained cells. Spectral CT parameters (diameter, water, and iodine concentrations of the lesion [WCL and ICL], the slope of the spectral Hounsfield unit curve [λHU], and CT values from 40 to 140 keV [at 10 keV intervals]) were compared among the three different grades. The correlation between quantitative spectral CT imaging parameters and Ki-67 LI was analyzed using Spearman correlation analysis.

Results:

Ki-67 LI in the IA group was significantly higher than in the pre/MIA group (p < 0.01). Grade 2 had higher diameter, WCL, and monochromatic CT values, and grade 1 had higher ICL and λHU. The WCL and monochromatic CT values were highly and positively correlated with Ki-67 LI. CT40keV had the highest correlation with Ki-67 LI, the diameter was moderately correlated with Ki-67 LI, and ICL and λHU were weakly correlated with Ki-67 LI.

Conclusions:

Spectral CT, a noninvasive diagnostic method, is valuable for predicting Ki-67 expression higher in IA, thus allowing preoperative evaluation of lung adenocarcinomas manifesting as GGNs.

Background:

Background: Celiac diseases are found to be associated with other autoimmune diseases such as autoimmune thyroiditis, type I diabetes, Addison’s disease, primary biliary cirrhosis, and inflammatory bowel disease (IBD). In literature, only a few cases were described simultaneously presenting both conditions in the same patient.

Case Presentation::

A 23-year-old Indian male presented with a one-month history of loose motion 10-12 times per day, having watery stool, and nocturnal diarrhea. The patient had pallor, weakness, fatigability, and anorexia/weight loss. The patient also had a history of periumbilical pain abdomen and black-colored stools. In our study, both conditions are clinically symptomatic in the same patient, as proved by endoscopic changes and histopathologically. Esophagogastroduodenoscopy (EGD) examination shows severe scalloping of duodenal folds and nodularity, indicating celiac disease changes. A colonoscopy examination was performed, which revealed multiple linear longitudinal ulcerations, friability, erosions and absent vascularity, which indicates Crohn’s disease. Duodenal biopsy shows celiac disease (Marsh IIIa), and Colonic biopsy shows Crohn’s disease. The patient was treated with improvement in abdominal pain, weight, and anemia.

Conclusion:

Celiac and Crohn’s both conditions are clinically symptomatic in the same patient, as proved by endoscopic and histopathological changes.

Background: IUDs are an effective, safe and comfortable contraception option for many women. IUD contraceptive users in North Mandrehe Health Center were 12 active acceptors and 3 new acceptors. The purpose of this study was to determine the affecting factors on the low interest of mothers in choosing an IUD as a contraceptive. Method: This study uses an analytical survey with a cross sectional approach. This research was conducted at North Mandrehe Health Center. The sample of this study was fertile age couple who used contraception as many as 98 respondents. The data were analyzed by performing Chi-square analysis and multiple linear analysis. Result: Based on the results of the study obtained variables of age, education, occupation, economy, knowledge, husband's support, socio-cultural, and health worker support have a relationship to the mother's interest in choosing an IUD as a contraceptive, while the variable that has no relationship was the parity variable. One of the main factors that most influence was the knowledge variable (OR = 8,766). Conclusion: The conclusion of this study showed that there were factors (age, education, occupation, economy, knowledge, husband's support, socio-cultural, and health worker support) that influence the mother's interest in choosing an IUD. It was suggested to health workers at North Mandrehe Health Center to intensely conduct counseling to the community, especially about IUD contraceptives.

The highest drop out of hormonal contraceptive users caused by side effects is the background for research on the use of herbal plants as antifertility substitutes for hormonal contraceptive which have minimal effects. Inggu leaves (Ruta angsutifolia) contain compounds that are interfering hormonal work such as saponins, tannins, chalepins and chalepensins, so it can be antifertitlity. To determine ethanol extract of inggu leaves effect on reducing the thickness of the smooth muscle of fallopian tube in female rats. The study used randomized post-test only controlled group was conducted using experimental animals (Wistar strain rats) divided into 4 groups with different doses (0; 0.4; 0.8; and 1.2 g/kg BW ) in February until April 2022. Measurement of the fallopian tube smooth muscle layer thickness using an Olympus CX23 microscope and ImageJ application.: Rat fallopian tube smooth muscle thickness was reduced along the dose of inggu leaf ethanol extract increased that statistically significant (p = 0.046). Ethanol extract of inggu leaves can reduce the fallopian tube smooth muscle thickness with an optimal dose of 1.2 g/kg BW.
