Modelling the adverse impacts of urbanization on human health
Authors: Pandey Prasoon , Uniyal Lubhna , Sharma Sandeep
Published: April 2024

Urbanization has been a growing trend for decades, but the Coronavirus disease 2019 (COVID-19) pandemic has accelerated this trend in several ways. In many countries, the pandemic has prompted significant investments in urban health infrastructure, including hospitals, clinics, and public health facilities. Also, there are many studies suggesting that COVID-19, urbanization, and chronic diseases are interconnected in several ways, and addressing one aspect requires a comprehensive approach that considers the interconnectedness of these factors. To date, there are no studies depicting COVID-19 as a cause of emerging chronic diseases within the urban population. To address this sensitive issue, we propose a mathematical model in which we divide the total human population into three compartments: susceptible, diseased, and recovered. We have obtained the equilibrium points of the model and the conditions for their local stabilities. A suitable Lyapunov function has been used to derive the condition for the global stability of the nontrivial equilibrium point. A detailed numerical simulation of the model has been carried out, which is followed by sensitivity analysis of the model system.
Heterogeneity characterization of commercial structural papers
Authors: Considine John , Keller D. Steven , Arvanitis Matthew A. , Tang Xiaoyan
Published: April 2024

Evaluation of physical and mechanical heterogeneity in commercial paperboards is needed to promote their use in structural applications, especially within the field of packaging. Understanding the range of their behaviors is needed to compete with other materials in the current marketplace and expand in others. This work describes the physical and stiffness heterogeneities of twelve commercial materials using tensile tests in the cross-machine direction and several inverse analyses. The effects of grammage, thickness, and apparent density on tensile stiffness were evaluated in both the linear elastic and nonlinear regimes. Thickness and density provided the best explanation for elastic heterogeneous behavior in most of the materials; local grammage was not the best descriptor for any material. The analyses used here were not able to provide a good explanation of the nonlinear behavior, which was attributed to the development of large shear strains within the materials as they neared failure. This work provides a methodology for additional heterogeneous behavior examinations.
The Burr distribution as an asymptotic law for extreme order statistics and its application to the analysis of statistical regularities in the interplanetary magnetic field
Authors: Bening Vladimir , Korolev Victor , Sukhareva Natalia , Xiaoyang Hong , Khaydarpashich Ruslan
Published: April 2024

The representability of the Burr distribution as a mixture of Weibull distribution is studied in order to justify its utility for modelling the statistical regularities in extreme values registered in non-stationary flows of informative events. A result of [24] is improved by extending the domain of admissible values of the parameters which provide the representability of the (generalized) Burr distribution as a scale mixture of the Weibull distribution. This result gives an argument in favour of application of the Burr distribution as a model of statistical regularities of extreme values registered within moderate regular time intervals, say, daily (short-term) extremes. In turn, if we are interested in the statistical regularities of the behaviour of the absolute extreme observation over a long period, say, a decade (the long-term extreme), then it can be noted that the daily extreme values form a sample of the Burr-distributed random variables. As is known, the Burr distribution belongs to the domain of max-attraction of the Fréchet distribution. The problem of improving the accuracy of the approximation of the distribution of the absolute extreme by the Fréchet distribution by the construction of an asymptotic expansion for the distribution of the extreme order statistics in the sample of independent identically Burr-distributed random variables is also considered. These results are illustrated by an example of fitting the Burr distribution to the data representing the extreme values of characteristics of the interplanetary magnetic field.

The value of language skills in Latvia: From socio-economic inequality to multilingual awareness
Authors: Rozenvalde Kerttu , Martena Sanita
Published: April 2024

This paper investigates the opposition between the realities and ideologies surrounding multilingualism in Latvia. Building mostly on Bourdieu’s theory of language in society, and multilingual awareness as a concept, we study the socio-economic value of multilingual repertoires in a multilingual setting (Latvia), and language users’ awareness of the link between their language competences (Latvian, Russian, English) and socio-economic status. By analysing sociolinguistic survey data, we demonstrate, firstly, that different multilingual repertoires are linked with differences in family income, level of education, and labour market position. Secondly, our data indicate that people generally do not acknowledge the link between their language skills and socio-economic status. To explore this further, we zoom in on language ideologies in formal education. We examine data on the multilingual awareness of Latvian language teachers from focus-group interviews and show that they tend to construe languages in competition, emphasise the symbolic value of Latvian, and ignore the multilingualism of their pupils and broader society. The study illuminates the dissonance between the multilingual realities of a post-Soviet EU country in which multilingual repertoires carry different values for individuals, and the Latvian-centred ideologies (disseminated by the teachers) that leave the presence of multilingualism and accompanying issues unacknowledged.

Published: April 2024

From productive and ecological point of view, Quercus robur L. is an extremely important species and the investigation of its anatomical properties is very significant in terms of its technical and technological utilization. The paper deals with the analysis of the wood fiber characteristics (fiber length, fiber lumen width, double-cell wall thickness, Runkel ratio) of mature pedunculate oak trees in the non-flooded (Management Unit "Vinična-Žeravinac-Puk") and flooded area (Management Unit "GVO 83 b"). One of the aims of the study is to determine the wood fiber quality and the possibility of use in paper and pulp production. When the mean values of the analysed anatomical characteristics are compared, the results show slightly higher values in the non-flooded area, except for the Runkel ratio. The radial pattern of the investigated characteristics depending on the age shows growth in the non-flooded area, while the same tendency in the flooded area was found for the fiber length only. It was recorded that fiber lumen width, double-cell wall thickness and Runkel ratio decreased in the final annual rings. The wood fiber quality for use in pulp and paper production is the greatest in the juvenile zone, unlike sapwood zone, regardless of the site conditions.

Published: April 2024

In this study, the genetic and phenotypic relations among tree height, diameter at breast height and survival at 18 years of age were investigated in Mediterranean cypress (Cupressus sempervirens L. var. horizontalis (Mill.) Gordon) provenance-progeny trials established in two locations in southern Türkiye. It was found that the variation among families within one provenance was higher than among different provenances. At the joint analysis, the narrow-sense heritability (hi2) was 0.36 for height, and 0.24 for diameter. Family mean heritability (hf2) was 0.78 for height, while it was 0.53 for diameter. Diameter showed higher (13.98%) genetic diversity than height (12.71%). Genetic correlation between traits was high (0.84). According to the breeding values of the families estimated by the BLUP method, when the best 50 families by two traits are selected separately, 12.5% genetic gain in terms of height and 13.2% in terms of diameter can be achieved. In the selection of the best 30 families, the estimated genetic gain calculated was 15.2% for height and 16.3% for diameter.
In the Name of “Freedom” and “Democracy”
Authors: Maškarinec Pavel , Novotný Lukáš
Published: April 2024

This article examines the rise of the populist radical right in the Czech Republic, where this party family had no parliamentary representation for many years. We show that by clarifying its ideological profile, the SPD achieved results in accordance with the social marginality and welfare chauvinism hypothesis. This is also confirmed by a spatial analysis, which shows that success of the SPD relied especially on mobilizing voters in traditional strongholds of the Czech left. In contrast, the Czech case yielded only very small support for the group threat effect and only mixed results for a U-shaped effect of age.

Authors: S Subimol. , Pathan Amjadkhan A.
Published: April 2024

Colon-targeted drug delivery systems can provide therapeutic benefits including better patient compliance and lower costs. The present investigation is aimed to design a colon specific microbially triggered system using biodegradable co-polymer mixtures. The calibration curves of 5-FU were measured in distilled water, 0.1N HCl and phosphate buffer of pH 6.8 and 7.4 which showed good linearity. Compatibility study of pure drugs, excipients and their physical mixtures were evaluated and passed as per standards. Solubility determination was carried out in different solvents. Satisfactory results were found from evaluation of micromeritic parameters such as flow property, in-vitro dissolution study and kinetic study.  The prime focus of the study was to design and evaluate a swelling dependent delayed release system for a colonic delivery of anticancer agent 5-Fluorouracil (5-FU) and further to determine the effects of carboxy polymer (Carbopol 71G-NF) on release behavior of 5-FU from a matrix tablet system containing different amounts of inulin (a biodegradable oligofructose) aiding in enzymatic degradation by colonic microflora. Mixed film coating with a blend of Ethyl cellulose: Eudragit®S-100 (2:1) at coat weight levels of 2%w/w, 4%w/w and 6.0%w/w was carried out respectively, which further retarded the drug release in the initial hours of the in-vitro dissolution profile. Swelling studies were also carried out on uncoated matrix tablet batches. The releases studies with or without rat cecal contents were performed on optimized batches and the samples were analyzed by a validated RP-HPLC method. In-vitro rat cecal study results revealed that complete drug release would occur from the tablets in the human colonic microenvironment. The study revealed an effective site-specific delivery of a hydrophilic chemotherapeutic agent, 5-FU to the colon for the treatment of various local as well as systemic pathologies.

Authors: Tiwari Ram Hari , Mangla Mohit , Sanduja Mohit , Nayak Amit Kumar
Published: April 2024

Diosgenin, a naturally occurring steroid sapogenin possessing diverse therapeutic properties, represents a bioactive compound of interest. However, its complete pharmaceutical utilization has been impeded by inherent challenges, primarily associated with poor aqueous solubility and stability. In the present investigation, we introduce an innovative methodology for fabricating diosgenin-encapsulated microspheres through the utilization of the spray drying technique. The spray drying process involves the transformation of a solution containing diosgenin into finely dispersed microspheres through atomization, followed by rapid drying in a hot air stream. Various formulation parameters, encompassing the selection of encapsulating material, surfactants, and process conditions, were methodically optimized to attain elevated encapsulation efficiency and precise control over release characteristics. The microspheres thus prepared underwent assessment for percentage yield, encapsulation efficiency, particle size, and in vitro drug release. Results indicate the generation of uniform microspheres exhibiting heightened diosgenin encapsulation and enhanced physical stability. Additionally, in vitro release studies demonstrated sustained and controlled diosgenin release from the microspheres, underscoring their potential for protracted therapeutic effects. Encapsulation efficiency, release kinetics, and physicochemical attributes of the microspheres were found to be contingent upon the choice of encapsulating material and process parameters. In conclusion, the fabrication of diosgenin-encapsulated microspheres employing the spray drying technique represents a promising strategy to augment the bioavailability and therapeutic efficacy of diosgenin. These microspheres hold considerable promise for applications within the pharmaceutical and nutraceuticals industries serving as a platform for the advancement of innovative drug delivery systems.
Improving Kinnow Fruit Classification with Feature Weighting using Modified Levy Flight Distribution-Inspired Sunflower Optimization Technique
Authors: Singh Sukhpreet , Malik Kamal
Published: April 2024

In this paper, Feature weighting is used to create an intelligent and effective classification method for Kinnow fruits. Feature weighting approach is used because it improves classification performance more than feature selection methods. The modified sunflower optimization algorithm (SFO) is proposed to search the optimal feature weights and parametric values of k-Nearest Neighbour (kNN).The levy flight distribution operator has been utilised to enhance the convergence speed of the sunflower optimization algorithm by improving the local and global search ability of the optimization algorithm. Also, the algorithmic parameter of the SFO algorithm has been adaptively selected using the linear time varying adaption method. In addition, tanh normalization technique is used for the data pre-processing to reduce the influence of outliers and dominating features before the feature weighting method. The findings suggest that the proposed wrapper based approach feature weighting technique is more capable of achieving higher accuracy than the existing strategies.

The research study dealt with Nano applications in the field of architecture, so that they achieve the goals and standards of building sustainability, and are used in the finishes of the external facades of buildings to reduce the cost, rationalize energy consumption, and extend the life span of the building, and have an advantage in terms of function and economic return in the long term.
An Analytical Study Of The Status Of Using Video-Based Online Learning In India (With Special Reference To SVBOLT And AVBOLT)
Authors: Gaur Mayank
Published: April 2024

New Media technology is changing education patterns rapidly. Online learning became an essential part of Education after COVID-19. The research explored the status of video-based online learning, the effectiveness of SVBOLT (synchronous video-based online teaching and learning) and AVBOLT (asynchronous video-based online learning and teaching), and the barriers and solutions to those encountered during online video-based learning. 80 teachers and 160 students from India's different regions, like Rajasthan, Uttar Pradesh, and Haryana, participated in this study. The study was conducted on students of the 8th class and above standard.  Teachers were selected who teach the students through offline and online modes.  Samples were collected randomly from the questionnaire via online and offline modes. The result states that while learning with the SVBOLT platform, students have to face various problems. During live webcasts through various apps, there is a fixed study time and place that cannot be changed, if, during this time they face internet connectivity issues, students can suffer from the problems. AVBOLT reduces the obstacles that were faced in learning through SVBOLT. AVBOLT is an effective platform compared to SVBOLT. AVBOLT enhances the teaching and learning experience.  Some aspects should be prioritized for effective online learning, such as Teachers should be trained for presentation in front of the camera and should have the necessary technical knowledge related to PPT (PowerPoint Presentation). AVBOLT provides error-free, quality content to learners.  The use of this blended education method (online and offline learning) is a worthy step in the direction of making studies completely online with new technologies. However, the institutes and the schools will have to ensure that their content is technically and educationally sound.

Authors: Gligor Laura Elena , Rusu Horațiu , Ciucă Gina-Agnes , Hirișcău Elisabeta Ioana , Domnariu Carmen Daniela
Published: April 2024

Background and aims. The introduction of accreditation criteria for hospitals has generated increased interest in applying the nursing process to clinical practice and developing nursing care plans. Nursing diagnosis plays a pivotal role in the formulation of these care plans.
The objective of the study is to investigate the correlation between nursing diagnosis education and nurses’ intentions, attitudes toward the use of nursing diagnosis and the behavior in using it in practice; to explore the differences between nurses’ intentions, attitudes and behavior, considering nurses’ socio-demographic and professional data.
Methods. A cross-sectional design was used. A web-based survey was applied to gather data. A sample of 664 hospital nurses was recruited from five Romanian hospitals.
Results. Education on nursing diagnosis showed significant results in relation to nurses’ intentions (F(2,126.35) = 23.99, p < 0.001), attitudes (χ2 (2,N = 664) = 44.62, p < 0.001) and behavior (F(2,167.69) = 29.53, p < 0.001) in using it in clinical practice. Nurses with education highly focused on nursing diagnosis have significantly stronger intention to use it, more positive attitudes and higher behavior in using it in clinical practice compared to nurses whose education simply had included a nursing diagnosis course, or nurses without any education on the topic. Significant differences were identified in intention (t (83.86) = -4.49, p < 0.001) and attitudes (U = 12697.50, z = - 3.99, p < 0.001, r = -0.0006) of management nurses compared to clinical nurses.
Conclusion. Nursing education on nursing diagnosis significantly impacts nurses’ intentions, attitudes, and behavior in their daily practice. Romanian nurses display slightly positive intention and attitudes toward nursing diagnosis but need more training for effective/practical clinical application.

Authors: Mishra RK  , Prusty S , Biswal AK
Published: April 2024

A reconnaissance survey was conducted on the uses and role of invasive alien species (IAS) to local livelihoods in the Chandaka Wildlife Sanctuary (CWS) located in Khurdha and cuttack district of Odisha, India. Vegetation of the sanctuary was sampled in 100 quadrates, each having 20 m×20 m through a combination of random and systematic sampling. Group discussions were also arranged with one hundred twenty local inhabitants (10 % of the total inhabitants) to document the various uses of IAS. A total of 18 alien plant species belonging to 8 different families, of which Asteraceae constitutes the highest number (7 species), include herb (5 species), shrub (1 species) and climber (1 species). The majority of the identified species were found to be used for medicine, followed by human food, fodder, insecticidal and ornamental purposes. It is true that the alien species have some negative impacts on local ecosystems, and not all of them are harmful. Therefore, assessment and careful documentation on utilization of invasive alien plant species of the sanctuary in terms of economic and social benefit to the local community can provide a possible and effective tool for management of IAS.

Published: April 2024

Показано, що наявність імпульсного шуму в сигналі може призвести до значного підвищення похибки відтворення сигналу при оцінюванні параметрів методом Проні. Для подолання цієї проблеми в роботі запропоновано 2 підходи: підхід з сегментуванням сигналу і використанням медіанного усереднення для коефіцієнтів поліному Проні і підхід з пропусканням точок з викидами. В ході комп’ютерних експериментів було показано, що обидва підходи здатні відтворювати сигнал в присутності імпульсного шуму краще, ніж традиційний метод власного вектору. При цьому якість відтворення методом пропускання точок сильно залежить від якості алгоритму детектування шумових імпульсів. Показано, що метод кореляційного аналізу для виділення імпульсних завад є достатньо точним для простих застосувань.

The reliability of cyber-physical systems (CPS) operation is based on the general problem minimization of multi-factor risks, the margin of permissible risk, the forecast of the destabilizing dynamics of risk factors, principles, hypotheses, and axioms that are directly related to the analysis of abnormal situations, accidents, and disasters. To ensure the reliable operation of the CPS, a digital twin is created, which accompanies the operation of the CPS throughout its life cycle. The design of digital twins is based on simulation modelling methods that provide the most realistic representation of a physical environment or object in the virtual world.
DE LA RELACIÓN DEL MANAGER Y EL EMPLEADO A LA APROXIMACIÓN DEL DESEO DEL INDIVIDUO
Authors: Ordoñez Abril Daniel Yiwady , Aguilera Cifuentes Carlos Iván
Published: April 2024

Este artículo es producto de uno de los capítulos del trabajo de investigación titulado “El directivo como psicoanalista: desde el ejercicio teórico”. El cual muestra que el directivo debe entender que los sujetos son para sí mismos, pero se reflejan para los demás y sus múltiples interpretaciones del mundo. Por tanto, el deseo, al ser el motor del psiquismo nace de la ley. Y el directivo debe verse como portador de la ley que libera el deseo, por lo que en la administración tanto el que analiza como el analizante son determinantes para facilitar nuevos constructos. De ahí, que se busque contribuir al desarrollo teórico de las ciencias humanas en la administración, abordando como tema principal el deseo del individuo en la organización. Con este antecedente, la investigación propone realizar una reflexión y problematizar la relación de poder existente entre el dirigente y el dirigido a partir de la visión de ser humano que se vincula con el poder; y lo importante que es ver al dirigente en la posición de analista para que pueda intervenir en dichas relaciones. Para este propósito, se emplearon referentes bibliográficos con inclinaciones psicoanalíticas basadas en la teoría freudiana. Como lo son Alomo, (2014), Bustos, (2016), Coll-Planas, (2009), Guattari, (2006), Lacan, (2008), López, (2013), Mumby, (2000), Restrepo, (2010), entre otros. Esto para dar otra mirada de análisis, que parte de la comprensión del fenómeno humano y social de las organizaciones empresariales. Y que permite encontrar entre otros resultados que, orientar el deseo a la escucha y al análisis supone procesos largos de formación que se logran con las vivencias adquiridas que afinan la escucha ante los discursos, y, donde el deseo puede ser considerado como una fábrica de individuos autónomos, responsables, inacabados y en construcción, con capacidad de construir y desarrollar cualquier proyecto.

INTRODUCTION Mandibular fracture poses a fatal complication because the mandible plays an essential role in occlusion and aesthetics. The mandible is one of the bones most affected by facial fractures commonly resulting from trauma to the face and may be associated with severe morbidity and serious consequences                              METHODS The records of 282 patients referred to RSUP Dr. Hasan Sadikin General Hospital Bandung, Indonesia between January 2017 and January 2021 were analysed retrospectively. Data including age, sex, etiology of mandibular fracture, type of mandibular fracture, and treatment. Incompleted data from the medical record were excluded.                                                                                    
RESULTS Men aged 17-30 years were the most common victims of mandibular fracture. Road traffic accidents (RTAs) were responsible in 84% of cases. The most common anatomic site for mandibular fracture was parasymphysis region 28.7 with simple fractures 79%, and 82% of the total fractures were treated with open reduction                                                                   
CONCLUSION The characteristics of mandibular fracture patients describe trauma patterns in the community. This finding is similar with some readily available literature with RTAs was the most common etiology and parasymphysis was the most common fracture site. Reasons for this high frequency may include the large number of poorly maintained, overloaded vehicles on unsuitable roads, violation of traffic regulations particularly by inexperienced young drivers.

Objectives The aim of this study was to analyze the viability and proliferation properties of the DFDBBX in MC3T3-E1 cell line Material and Methods Bovine was milled to reach nano sizes of 100-200 nm. We used 2 mg/mL, 4 mg/mL and 8 mg/mL to incubate MC3T3-E1 cells in the following experiment. Immunocytochemistry methods were performed using a Live/Dead cell imaging kit to investigate the viability of MC3T3-E1. To investigate the proliferation of MC3T3-E1, ICC was performed using an anti-Ki67 antibody. Using a confocal laser scanning microscope (CLSM), the cells were observed at LSIH Brawijaya University. Statistical analysis was performed using the one-way analysis of variance (ANOVA) at p < 0.05 Results The highest intensity of living cells was DFDBBX 8 mg/ml on day 7 (739.46 A.U.; p < 0.05), indicating that DFDBBX 8 mg/ml had an effect of increasing cell viability two times compared to control. Ki67 intensity in MC3T3-E1 cell culture was highest on day seven and treated DFDBBX 8 mg/ml (186.04 A.U.; p< 0.05), which indicated the proliferation of MC3T3-E1 cells increased nine times compared to the first day and two times greater than the control group Conclusion DFDBBX have great viability and proliferation properties, which shows potentially as biomaterials to repair bone loss

Published: April 2024

Objective: RANK-RANKL-OPG signaling is being considered as the pathway periodontitis induces osteoclastogenesis. Alveolar bone resorption and increased osteoclast activity are both triggered by a greater RANKL/OPG ratio in periodontitis. Gambir contains catechins and quercetin, which have antimicrobial, antioxidant, and anti-inflammatory properties. This study aimed to analyze the anti-osteoclastogenesis effect of gambir extract gel through RANKL and OPG serum levels, the number of osteoblasts, and osteoclasts in alveolar bone tissue of Wistar rats. Material and Methods: Twenty-four male Wistar rats were divided into four equal groups, each receiving a different treatment: Group I received a placebo gel, Group II received Tetracycline gel, Group III received 8% gambir extract gel, and Group IV received 10% gambir extract gel. After 21 days, the serum levels of RANKL and OPG were assessed using ELISA. Hematoxylin-eosin staining of the bone tissue preparation was followed by microscopic counting of osteoblasts and osteoclasts. Results: Significant differences in RANKL serum levels were seen in Group I (0.70 + 0.020) with Group III (0.031 + 0.014) (p=0.018) and Group I with Group IV (0.038 + 0.012) (p=0.041). Serum levels of OPG differed significantly between Groups I (0.165+0,125) and IV (0.536+0.182) p=(0.015). The number of Osteoblast in Group I (1.16+ 0.40) and IV (1.33+1.03) were significantly different (p=0.023). The number of Osteoclast in Group I (4.33+1.50) and IV (1.5+0.83) were significantly different (p=0.008). Conclusion: Gambir Extract Gel 10% inhibits osteoclastogenesis by increasing osteoblast and decreasing osteoclast numbers by more than 8%, decreasing RANKL, and elevating OPG serum levels.

Communicating at face value
Authors: Brannigan Michael C.
Published: April 2024

Srikant Sarangi's rich and provocative insights clearly merit robust inquiry. In resounding endorsement of his spot-on driving thesis of communication as “action/meaning-making practice,” let us stretch beyond our disciplinary corridors and embark on a brief phenomenological and ontological dig to further challenge the quarantining of communication to a template of skills and behavior.
