Deformation of unsaturated collapsible soils under suction control
Authors: Al-Obaidi Qasim A. , Schanz Tom 
Published: August 2022

Abstract
Collapsible soils present significant geotechnical and structural engineering challenges worldwide. They can be found in arid or semi-arid regions and are directly affected by the multi-step wetting procedure due to the reduction of soil suction. The main objectives of this paper are to investigate the volume change behaviour, collapse mechanism and deformation characteristics under the control of suction and net vertical stress. In this study, three types of collapsible soils were investigated such as natural soils of sandy gypseous, silty loess, and artificial soil of gypsum–sand mixture. A series of constant net stress-suction control (wetting and drying) tests using a combination of axis-translation and vapor equilibrium techniques were deployed to cover a wide range of applied suction. The test results show that large volume change and collapse deformation occur upon a stepwise suction decrease. On the other hand, shrinkage behaviour resulting from increases in imposed suction is observed during the drying path. The collapse deformation depends on the stress path and is a function of net normal stress, suction, dry density, and degree of saturation. The water content and the degree of saturation dramatically increase as the applied suction decreases from the initial high to zero values at the drying path.

Published: August 2022

Abstract
In this paper, a discrete Leslie-Gower predator-prey system with Michaelis-Menten type harvesting is studied. Conditions on the existence and stability of fixed points are obtained. It is shown that the system can undergo fold bifurcation, flip bifurcation, and Neimark-Sacker bifurcation by using the center manifold theorem and bifurcation theory. Numerical simulations are presented to illustrate the main theoretical results. Compared to the continuous analog, the discrete system here possesses much richer dynamical behaviors including orbits of period-16, 21, 35, 49, 54, invariant cycles, cascades of period-doubling bifurcation in orbits of period-2, 4, 8, and chaotic sets.

Authors: Melnik Tatiana , Sierova Liudmyla 
Published: August 2022

Abstract
The development of world economic relations leads to the intensification of mutual exchange of goods between countries. In the article, we have analyzed the dynamics and structure of Ukraine’s external trade, assessed the degree of import dependence of the domestic market, and determined preconditions and national potential of import substitution of goods, including high-tech ones. We have determined public policy areas of import substitution in Ukraine, which include formation of the list of import-substituting goods, stimulation, export diversification, and the industrial and innovative development of the economy. The purpose of the article is to study the imbalances in Ukraine’s external trade in the context of the implementation of import substitution policy. The article analyzes the statistical and economic indicators, with a view to achieving the final research aims, in the period from 2010 to 2022 in Ukraine, in the service of military actions from 2014, and a full-scale invasion in January 2022, as well as conditions in the pandemic years (2019–21). Other countries are also considered concomitantly. We have drawn conclusions on the tendencies to increase the share of imports in the domestic market and proposed recommendations for the development of effective functioning of the internal market.
Emerging trends and knowledge domain of research on urban green open spaces and wellbeing: A scientometric review
Authors: Shrivastava Akansha , Mehrotra Surabhi 
Published: August 2022

AbstractGreen Open Spaces (GOS) and its linkages to human health and wellbeing have received growing attention in the field of urban planning. In spite of increase in number of studies in this field, there is lack of scientometric perspective pertaining to this research domain. The purpose of the study is to map the research status and key research directions in the interdisciplinary domain: Green open spaces, public health and urban planning, using Citespace. Scientometric analysis (co-author, co-citation, co-word and cluster analysis) is conducted for 451 peer reviewed publications, primarily published in last two decades (2000–2021) in the web of science database. The study assessed influential authors, journals and documents to identify the intellectual structure and network of co-authorship and countries to understand research collaborations of this domain. As a result of this review, five emerging research trends in this domain are identified - Emerging data sources, Study areas at various spatial scales, Type of study, Assessment of urban GOS benefits and Urban planning contribution in the research area. In addition, critical review of these trends is conducted to understand corresponding challenges and opportunities. The critical analysis highlighted the need of generating evidence base appropriate for assessing GOS use and user perception, especially in developing nations capturing socio-demographic diversity. The use of Citespace for scientometric analysis facilitated the systematic understanding of this research area by visualizing and analyzing various patterns and trends. This study provides an intensive understanding of present research status and emerging trends of this research domain. Findings in this study are envisioned to provide practitioners, decision makers and researchers with promising future research directions.

Abstract
In diesem Beitrag werden die Herausforderungen und Lösungen zur kosteneffizienten additiven Herstellung von keramischen Mikrostrukturen dargestellt. Indem bereits während des Design-Prozesses die Gestalt an die fertigungsspezifischen Anforderungen angepasst wird, kann ein Bauteil mit hohen Qualitätsanforderungen ohne notwendige nachfolgende Bearbeitungsverfahren wie Schleifen additiv hergestellt werden. Durch den Einsatz der badbasierten Photopolymerisation können so Maschinen- und Werkzeugkosten vermieden und der Vorteil der geometrischen Flexibilität ausgenutzt werden.

Published: August 2022

People’s knowledge, attitudes, and practices related to health are built throughout life, particularly during childhood and adolescence, and they reflect the practices of their family and social circle. The aim of this study was to identify the levels of knowledge, attitudes, and practices related to oral health of first-year university students at the Paraíso Campus of the University of Costa Rica. This was done through a questionnaire of closed questions that would allow oral health educational strategies to be established in the future for this population group. For this purpose, a cross-sectional descriptive study was conducted, where 70 first-year students of the Paraíso Campus participated in the first semester of the year 2019. For data collection, a survey of 22 closed questions on knowledge, attitudes, and practices about oral health was applied, and a score on oral health knowledge was subsequently performed, based on the answers to the questions. According to the results, the level of knowledge shown about oral health is low, since the average knowledge score (7.02 points) was less than half of the maximum score (17 points). The greatest deficiency in knowledge was evidenced in topics, such as, dental biofilm, gingivitis, use of fluorides, and the role of saliva. In addition, several practices that affect the condition of the oral cavity were identified, such as harmful habits, inadequate nutrition, and poor oral hygiene habits. In this study, a general lack of knowledge was identified regarding basic concepts of oral health in young university students, who are not clear about the role of some protective or risk factors related to the main oral diseases.

Phloretin Improves Ultrafiltration and Reduces Glucose Absorption during Peritoneal Dialysis in Rats
Authors: Bergling Karin , Martus Giedre , Öberg Carl M. 
Published: August 2022

Significance Statement
In peritoneal dialysis, ultrafiltration is achieved at the cost of systemic glucose absorption with succeeding treatment-induced metabolic side effects and comorbidities. The transport pathway mechanisms that enable glucose transport and the extent to which they individually contribute to mass transfer are not fully understood. Intraperitoneal administration of phloretin, a nonselective blocker of facilitative glucose transporters (GLUTs), reduced glucose absorption and improved ultrafiltration during peritoneal dialysis in rats. Because GLUTs are also present in the human peritoneal membrane, phloretin or similar acting agents could reduce the metabolic cost of ultrafiltration and improve outcomes of peritoneal dialysis.

Background
Harmful glucose exposure and absorption remain major limitations of peritoneal dialysis (PD). We previously showed that inhibition of sodium glucose cotransporter 2 did not affect glucose transport during PD in rats. However, more recently, we found that phlorizin, a dual blocker of sodium glucose cotransporters 1 and 2, reduces glucose diffusion in PD. Therefore, either inhibiting sodium glucose cotransporter 1 or blocking facilitative glucose channels by phlorizin metabolite phloretin would reduce glucose transport in PD.

Methods
We tested a selective blocker of sodium glucose cotransporter 1, mizagliflozin, as well as phloretin, a nonselective blocker of facilitative glucose channels, in an anesthetized Sprague–Dawley rat model of PD.

Results
Intraperitoneal phloretin treatment reduced glucose absorption by >30% and resulted in a >50% higher ultrafiltration rate compared with control animals. Sodium removal and sodium clearances were similarly improved, whereas the amount of ultrafiltration per millimole of sodium removed did not differ. Mizagliflozin did not influence glucose transport or osmotic water transport.

Conclusions
Taken together, our results and previous results indicate that blockers of facilitative glucose channels may be a promising target for reducing glucose absorption and improving ultrafiltration efficiency in PD.

Introducción: la ventilación mecánica es una práctica común en las unidades de cuidados intensivos y anestesiología. Tiene implicaciones terapéuticas, pero también es potencialmente nociva para el sistema respiratorio y los órganos distantes, por lo cual es imprescindible monitorizar los parámetros ventilatorios de manera continua.
Objetivo: describir la ecuación del movimiento del sistema respiratorio y sus aplicaciones clínicas en el paciente bajo ventilación mecánica.
Desarrollo: la ecuación del movimiento del sistema respiratorio integra las fuerzas dinámicas generadas por el ventilador y las propiedades intrínsecas del pulmón y la caja torácica. Expresa la presión en el sistema respiratorio en relación con el volumen, la elastancia, la resistencia, el flujo de aire y las presiones generadas por el ventilador y el paciente. Las presiones elevadas en el sistema respiratorio se asocian a una mayor mortalidad en pacientes con ventilación mecánica, por lo que la identificación de los componentes que condicionan la elevación de las presiones mediante la ecuación del movimiento del sistema respiratorio permite realizar modificaciones a los parámetros programados del ventilador para mantener una ventilación protectora.
Conclusión: la toma de decisiones basada en la ecuación del movimiento del sistema respiratorio permite realizar ajustes en los parámetros ventilatorios según las características y enfermedades del paciente bajo ventilación mecánica.

Inventory for Critical Managerial Soft Skills (ICMS) – Development and Standardisation
Authors: Vadhana R. Chandra , Zakkariya K.A. 
Published: August 2022

Purpose: This paper presents the findings of a group of empirical studies for a conceptual and theoretical validation of the Critical Managerial
Soft Skills (CMS) Model and then presents the psychometric properties of a newly developed tool - The Inventory for Critical Managerial Soft Skills
(ICMS) for assessing the same. Design/methodology/approach: The CMS model was validated by a set of qualitative and quantitative studies among employers to confirm the importance of soft skills and to derive the critical soft skills framework (N-95, 206) and this served as a basis of the tool construction. ICMS has been then psychometrically validated for the group of management graduates by conducting a series of qualitative and quantitative research steps (N-975) Findings: ICMS is a self-reported scale for measuring seven critical managerial soft skills of managerial candidates, namely, Communication skills, Leadership skills, Interpersonal and Teamwork skills, and Self-Management Skills, Decision-making skills, Goal setting skills, and Task efficacy. Research limitations/implications: The tool developed is limited to the measurement of only the seven dimensions which are derived as “critical” based on various stages of the work.
Practical implications: The tool can be used for recruitment screening andvas a pre and post-training assessment tool for soft skills development of
management students. Social implications: The tool can be used during management education tovhelp the students understand their levels of soft skills and accordingly suitable measures can be undertaken to improve upon during the course of study to enhance their employability. Originality/value: The tool is fully original and has highly useful for researchers and practitioners as it has been empirically validated using appropriate and adequate statistical measures.
