One of the most significant issues faced by many low- and middle-income nations, including South Africa, is ensuring access to healthy, affordable, and sustainable food. South Africa is renowned worldwide for its rich biodiversity and a vast body of traditional knowledge among those who consume forest foods. However, despite ecological diversity, frequent barriers remain to getting diversified household diets. This study sought to investigate the contribution of trees and green spaces to household food security in eThekwini. A total of 280 households met the inclusion criteria and consented to participate in this study by responding to questionnaires. The collected data were analysed using descriptive statistics, the computation of the Household Food Insecurity Access Scale (HFIAS), and the Instrumental Variable Poisson model. The study’s results revealed that only 29% of the respondents were food secure, 36% were mildly food insecure, 27% were moderately food insecure, and 8% were severely food insecure. The Instrumental Variable Poisson model results revealed that cultivated green spaces, wealth index, gender, education level of the head of households, and grants had a negative correlation with household food insecurity. On the other hand, non-cultivated green spaces, local trees, age, marital status, number of dependents, and monthly income positively correlated with food insecurity. Given the existence of trees and green spaces in eThekwini, there is potential for food security solutions to be formed around both cultivated and uncultivated green spaces to promote sustainable access to food and nutritious diets in low-income households. Policy interventions should adopt an approach that encourages the incorporation of foods from both cultivated and uncultivated trees and green spaces in people’s diets.
Do Reputation Incentives Matter? Busy Directors and Corporate Social Responsibility in China
Authors: Wang Qi , Sun Maoxia , Wang Kongwen
Published: March 2023

This paper aims to examine the effect of busy directors on corporate social responsibility (CSR) based on their directorships’ reputation incentives. Using the panel data of Chinese-listed companies in the Shanghai and Shenzhen stock exchange between 2016 and 2021, fixed-effects panel regression analysis is employed as the empirical methodology. In so doing, we find that the effect of busy directors on CSR appears to be nonlinear. Then, by focusing on the relative size of the firms served by busy directors, our study further shows that busy directors can improve CSR in their relatively more prestigious directorships. Nevertheless, busy directors may induce negative CSR in their relatively less prestigious directorships. These results together identify reputation incentives as one factor in determining whether busy directors affect CSR. Therefore, we conclude that reputation is an effective mechanism that can motivate busy directors to monitor and advise CSR.
Traversable Wormhole Solutions Admitting Noether Symmetry in f(R,T2) Theory
Authors: Gul Muhammad Zeeshan , Sharif Muhammad
Published: March 2023

This paper uses the Noether symmetry approach to examine the viable and stable traversable wormhole solutions in the framework of the f(R,T2) theory, where R is the Ricci scalar and T2=TμνTμν is the self-contraction of the stress–energy tensor. For this purpose, we consider a specific model of this modified theory to obtain the exact solutions of the Noether equations. Further, we formulate the generators of the Noether symmetry and first integrals of motion. We analyze the presence of viable and stable traversable wormhole solutions corresponding to different redshift functions. In order to determine whether this theory provides physically viable and stable wormhole geometry or not, we check the graphical behavior of the null energy constraint, causality condition and adiabatic index for an effective stress–energy tensor. It is found that viable and stable traversable wormhole solutions exist in this modified theory.

Published: March 2023

Project implementation is one of the key activities in the process of ensuring development. In public institutions, the challenges in project management are particularly evident. Organizational inflexibility and an inability to adequately evaluate work are particularly emphasized, often creating problems during project implementation. These challenges become even greater if the financing of the project is planned with EU grants or other financial instruments that require great precision and thus exceptional project management skills. This document will present an effective project management model, as well as programs and portfolios in regional self-government units. A methodology has been developed to encourage the transformation of public systems from rigidly functional to project systems. The methodology was tested in Primorje-Gorski Kotar County, Republic of Croatia. An analysis of the quality of implementation of twenty projects has been carried out: an analysis of the final results of ten projects in which the methodology has been applied and of ten projects in which the methodology has not been applied. After conducting empirical research and analysis, the quality of the proposed model was proven at all levels of governance within the public sector. By applying this methodology, significant advances can be made in the quality of realized projects while ensuring the realistic dynamics of this realization and rational financial costs.

Evaluation of patient radiation dose after the implementation of a high kV technique during a cerebral angiographic procedure is an important issue. This study aimed to determine and compare the patient radiation dose of intracranial aneurysm patients undergoing cerebral angiography using the conventional and high kV techniques in a retrospective study and a phantom study. A total of 122 cases (61 cases with conventional technique and 61 cases with high kV technique) of intracranial aneurysm patients, who underwent cerebral angiographic procedure and met the inclusion criteria, were recruited. The radiation dose and the angiographic exposure parameters were reviewed retrospectively. The radiation dose in the phantom study was conducted using nanoDotTM optically stimulating luminescence (OSLD), which were placed on the scalp of the head phantom, the back of the neck, and the phantom skin at the position of the eyes. The standard cerebral angiographic procedure using the conventional and high kV techniques was performed following the standard protocol. The results showed that the high kV technique significantly reduced patient radiation dose and phantom skin dose. This study confirms that the implementation of a high kV technique in routine cerebral angiography for aneurysm diagnosis provides an effective reduction in radiation dose. Further investigation of radiation dose in other interventional neuroradiology procedures, particularly embolization procedure, should be performed.

Authors: Islam Md. Monjurul , Mohana Anika Amir , Rahman Md. Aminur , Rahman Mahbubur , Naidu Ravi , Rahman Mohammad Mahmudur
Published: March 2023

Chromium (Cr) exists in aqueous solution as trivalent (Cr3+) and hexavalent (Cr6+) forms. Cr3+ is an essential trace element while Cr6+ is a dangerous and carcinogenic element, which is of great concern globally due to its extensive applications in various industrial processes such as textiles, manufacturing of inks, dyes, paints, and pigments, electroplating, stainless steel, leather, tanning, and wood preservation, among others. Cr3+ in wastewater can be transformed into Cr6+ when it enters the environment. Therefore, research on Cr remediation from water has attracted much attention recently. A number of methods such as adsorption, electrochemical treatment, physico-chemical methods, biological removal, and membrane filtration have been devised for efficient Cr removal from water. This review comprehensively demonstrated the Cr removal technologies in the literature to date. The advantages and disadvantages of Cr removal methods were also described. Future research directions are suggested and provide the application of adsorbents for Cr removal from waters.

Development of an IgY-Based Treatment to Control Bovine Coronavirus Diarrhea in Dairy Calves
Authors: Bok Marina , Vega Celina G. , Castells Matias , Colina Rodney , Wigdorovitz Andrés , Parreño Viviana
Published: March 2023

Bovine Coronavirus (BCoV) is a major pathogen associated with neonatal calf diarrhea. Standard practice dictates that to prevent BCoV diarrhea, dams should be immunized in the last stage of pregnancy to increase BCoV-specific antibody (Ab) titers in serum and colostrum. For the prevention to be effective, calves need to suck maternal colostrum within the first six to twelve hours of life before gut closure to ensure a good level of passive immunity. The high rate of maternal Ab transfer failure resulting from this process posed the need to develop alternative local passive immunity strategies to strengthen the prevention and treatment of BCoV diarrhea. Immunoglobulin Y technology represents a promising tool to address this gap. In this study, 200 laying hens were immunized with BCoV to obtain spray-dried egg powder enriched in specific IgY Abs to BCoV on a large production scale. To ensure batch-to-batch product consistency, a potency assay was statistically validated. With a sample size of 241, the BCoV-specific IgY ELISA showed a sensitivity and specificity of 97.7% and 98.2%, respectively. ELISA IgY Abs to BCoV correlated with virus-neutralizing Ab titers (Pearson correlation, R2 = 0.92, p < 0.001). Most importantly, a pilot efficacy study in newborn calves showed a significant delay and shorter duration of BCoV-associated diarrhea and shedding in IgY-treated colostrum-deprived calves. Calves were treated with milk supplemented with egg powder (final IgY Ab titer to BCoV ELISA = 512; VN = 32) for 14 days as a passive treatment before a challenge with BCoV and were compared to calves fed milk with no supplementation. This is the first study with proof of efficacy of a product based on egg powder manufactured at a scale that successfully prevents BCoV-associated neonatal calf diarrhea.

Despite being relatively rare, Mediterranean tropical-like cyclones, also known as Medicanes, induce significant impacts on coastal Mediterranean areas. Under climate change, it is possible that these effects will increase in frequency and severity. Currently, there is only a broad understanding of the types and mechanisms of these impacts. This work studied Medicane Ianos (September 2020) and its effects on the Ionian Islands, in Greece, by developing a database of distinct impact elements based on field surveys and public records. Through this archive, the study explored the range of Ianos’ impacts to develop a systematic categorization. Results showed different types of effects induced on the natural and the built environment that can be grouped into 3 categories and 39 sub-categories in inland and coastal areas, indicating an extensive diversity of impacts, ranging from flooding and geomorphic effects to damages in various facilities, vehicles and infrastructure. The systematic description of the typology of Medicanes’ effects presented in this study is a contribution to a better understanding of their consequences as means to improve our ability to prepare for, respond to, and recover from them, a necessary stepping stone in improving the overall preparedness of both the general public and relevant authorities.
Characterization of Bubble Transport in Porous Media Using a Microfluidic Channel
Authors: Haggerty Ryan , Zhang Dong , Eun Jongwan , Li Yusong
Published: March 2023

This study investigates the effect on varying flow rates and bubble sizes on gas–liquid flow through porous media in a horizontal microchannel. A simple bubble generation system was set up to generate bubbles with controllable sizes and frequencies, which directly flowed into microfluidic channels packed with different sizes of glass beads. Bubble flow was visualized using a high-speed camera and analyzed to obtain the change in liquid holdup. Pressure data were measured for estimation of hydraulic conductivity. The bubble displacement pattern in the porous media was viscous fingering based on capillary numbers and visual observation. Larger bubbles resulted in lower normalized frequency of the bubble breakthrough by 20 to 60 percent. Increasing the flow rate increased the change in apparent liquid holdup during bubble breakthrough. Larger bubbles and lower flow rate reduced the relative permeability of each channel by 50 to 57 percent and 30 to 64 percent, respectively.

Dam reliability analysis is performed to determine the structural integrity of dams and, hence, to prevent dam failure. The Chenderoh Dam structure is divided into five parts: the left bank, right bank, spillway, intake section, and bottom outlet, with each element performing standalone functions to maintain the overall Dam’s continuous operation. This study presents a numerical reliability analysis of water dam reservoir banks using fluid–structure interaction (FSI) simulation of the bottom outlet structures operated at different discharge conditions. Three-dimensional computer-aided drawings were used to view the overall Chenderoh Dam. Next, a two-way fluid–structure interaction (FSI) model was developed to explore the influence of fluid flow and structural deformation on dam systems. The FSI modeling consists of Ansys Fluent and Ansys Structural modules to consider the boundary conditions separately. The reliability and performance of the reservoir bottom outlet structure was effectively simulated and recognised using FSI. The maximum stress on the bottom outlet section is 18.4 MPa, which is lower than the yield stress of mild steel of 370 MPa. Therefore, there will be no structural failure being observed on the bottom outlet section when the butterfly valve is fully closed. With a few exceptions, the FSI models projected that bottom outlet structures would be able to run under specified conditions without structural collapse or requiring interventions due to having lower stress than the material’s yield strength.
Effect of Directional Auditory Takeover Request on Takeover Behavior and Eye Movement in Conditionally Automated Driving
Authors: Ma Jun , Guo Yixun , Xu Wenxia , Li Jiateng
Published: March 2023

Conditionally automated driving (CAD) systems allow the driver to temporarily disengage from driving tasks. The significant concern of CAD is to ensure a safe and timely transition to the manual driving mode when the system exceeds its limits and issues a takeover request (TOR). The aim of this study was to investigate the effect of directional auditory TOR on the driver takeover process. A within-subject experimental design was used: twenty-four participants drove four times in an automated driving simulation scenario and received two non-directional auditory TORs and two directional auditory TORs (TOR directions corresponding to the orientation of potential hazards). The takeover behavior and eye movement characteristics relevant to the takeover process were collected. The results showed that directional auditory TOR enabled drivers to shift their visual attention to the hazards’ area faster than non-directional auditory TOR, accelerating the driver’s understanding of the road environment and improving takeover behavior. The study may provide a reference for the design of takeover requests for conditionally automated driving.

Authors: Ignatenko G. , Turkin V. , Sviderskaya O. , Belyaev V. , Zubko S.
Published: March 2023

The simulation of the working processes of the MAN D&T MC series marine diesel engine was carried out in

order to reduce carbon dioxide emissions with exhaust gases. The purpose of the simulation was to find design

and operational solutions that affect CO2 emissions. When performing a computational study, a mathematical

model of a combined internal combustion engine implemented in the DIESEL-RK computer program was used. The studied variables are the compression ratio, the advance angle and the duration of fuel injection, the values

of which can be set without making significant changes to the engine design. Mathematical models are obtained

in the form of regression equations that describe the effect of the studied fuel supply parameters (compression

ratio, fuel injection advance angle and fuel injection duration) on the target functions - specific carbon dioxide

emission and effective power of the 6S60MC diesel engine. To determine the coefficients of the regression

equation, planning of a complete factorial experiment of the second order is implemented. In order to find the

minimum value of carbon dioxide emissions using the generalized reduced gradient method, the problem of

choosing the optimal values of the compression ratio, fuel injection duration and fuel injection advance angle

for a given effective power of a 6S60MC marine diesel engine is solved. It is shown that, for example, with an

engine power of 10,000 kW, the reduction in carbon dioxide emissions by optimizing the specified fuel supply

parameters will be 7.37%

Authors: Ignatenko G. , Turkin Vladimir Antonovich , Belyaev V. , Sviderskaya O. , Zubko S.
Published: March 2023

To clean the exhaust gases of engines from carbon, nitrogen and sulfur oxides, a method and device are proposed,

the principle of which is based on the fact that the exhaust gases pass through an absorber, where they

are cleaned of nitrogen and sulfur oxides, and then through adsorption sections filled with granules of slag

pumice and are purified from carbon oxides as a result of their adsorption. Carbon dioxide, interacting with

water particles in the pores of the granules, forms carbonic acid. Then the diluted carbonic acid condensate

after cleaning in the separator from solid impurities is discharged overboard. The composition of a shipboard

system for continuous laser monitoring and control of emissions of carbon, nitrogen and sulfur oxides contained

in the exhaust gases of engines by adjusting their adjustment parameters, as well as using a device for complex

exhaust gas purification, is proposed. An algorithm for solving the problem of fulfilling the requirements of

regulation 20 "Achievable EEDI" of Appendix VI of the MARPOL 73/78 Convention on carbon oxide emissions

has been developed. The implementation of the proposed algorithm is possible using a system for cleaning

combustion products from harmful oxides

The article analyzes the main normative documents, according to which the foreign policy of the Republic of Moldova is formed. The main factors influencing the development of the country's foreign policy are considered. Also the main threats and challenges to the country's sovereignty and territorial integrity have been identified. Changes in the declared priorities of Moldova 's foreign policy, especially on the european and eurasian vectors, have been studied. Since declaring independence in 1991, the country has inherited the same problems that are common to most post-Soviet countries, namely: separatism of certain territories, bifurcation of society, some seek to a european future, and others - nostalgia for the Soviet past, economic imbalance , political immaturity and corruption of elites; legal nihilism, etc. This was reflected in the basic documents designed to shape the foreign policy of the republic. The purpose of the study is to analyze the regulatory frameworkof the foreign policy of the Republic of Moldova since independence to the present time, taking into account current trends in international relations. The Constitution, acts that should ensure the functioning system of the national security and defense, the Concept of Foreign Policy of the Republic of Moldova are the main documents governing the country's foreign policy. Since independence, there have been changes in setting Moldova's foreign policy priorities. They concerned issues of ensuring the national security of the country, identified threats and challenges facing it. The need for European integration and active participation in the processes of regional political and economic cooperation was recognized. At the same time, the development of a new foreign policy strategy remains relevant, that would meet the current conditions of the international situation, the challenges associated with hybrid threats in the post-Soviet space; would take into account new trends in the relations of the Republic of Moldova with the EU, the USA, etc. At the same time, this document should offer new ways of international assistance in overcoming the country's socio-economic problems, solving the Transnistrian conflict, and so on.
Working routine of a professional community as a field of historical studies: main methodological approaches
Authors: Volonyts Vira ,   Mariupol State University
Published: March 2023

The article covers methodological-theoretic approaches to study a day-to-day world of a profession as a subject of interdisciplinary historical-anthropological research. Theoretical achievements in philosophy, social science, anthropology, cultural anthropology, anthropology of a profession were analyzed in the article, which enables methodological synthesis execution to characterize professional group routine in social context. Structural-anthropological approach serves to define the components of worth and symbolism, conceptual factors of a daily working routine of a professional, determined by peculiarities of a professional working cycle. The concept of «detailed description», which was introduced as one of the approaches, gives a chance to examine a person who is in a certain historical-social reality and who is constantly changing by gaining a different background and professional experience as well. Functionality has given special cognitive status to the profession as a social institution. Structural-functional and interactional approaches have given creative impulse to empirical research of professions, enlarging the subject concept by adding studies on marginal working activities, professional subcultures, influence of local contexts on professional surroundings. Phenomenology makes it possible to study daily practices that stand in and beside professional activity from an individual perception. Social study’s approach shows the impact of a profession on people’s behavior and reflexology of professional groups stating that each profession requires corresponding mental accommodation. Similar cognitive emotional behavioral reactions form special professional identity, which could be examined in social-spatial and social-temporary dimensions.

Quantitative and qualitative research models were used together in the study. The survey method was used in the qualitative part and the phenomenological method was used in the quantitative part of the study. The study group of the study is comprised of 77 participants from 13 different nationalities with Turkish language proficiency levels of A2, B2 and C1. Quantitative data were collected by using the “Oral Communication Strategies Inventory” and qualitative data were collected by using a semi-structured interview form. Descriptive analysis was performed on both the quantitative and qualitative data. The results of the study revealed a strong correlation between the level of competence and the tendency to use strategies. Participants with low language proficiency levels tend to use strategies including the behavior of moving away from the verbal boundaries of the target language. On the other hand, those with a high level of language proficiency tend to use strategies that include the effort to stay within the boundaries of the target language. In the qualitative dimension of the study, 10 different communication strategies were determined based on the episodic memories and experiences of the participants. These are strategies mostly used in compensatory functions.

In the first part of the structured questionnaire consisting of three parts, there are questions to determine gender and grade, in the second part there are questions to determine the music listening habits of the students, and in the last part there is the Intangible Cultural Heritage Attitude Scale, the validity and reliability study of which was conducted by Gürel and Çetin (2019). The analyses within the scope of construct validity of the measurement tool were made and evaluated to be appropriate. In addition, as a result of the reliability analysis applied to the entire scale, Cronbach’s Alpha result was calculated as .871. Independent samples t-test and one-factor analysis of variance (ANOVA) were used to analyse the data obtained from the research. According to the results of the analyses, when the music listening habits of high school students and their attitudes towards intangible cultural heritage elements were examined, it was determined that there was no significant relationship according to gender, grade level, music listening tool, frequency of allocating special time for music listening and Turkish lyrics of music. In addition, it was determined that there was a significant difference between the type of music students listened to and their attitudes towards intangible cultural heritage elements.
Individual Innovativeness Levels of Science Teacher Candidates

Published: March 2023

This study is intended to detect the level of individual innovativeness among science teacher candidates and to demonstrate whether levels of individual innovativeness differ based on different variables like gender, grade level, reception or lack of preschool education and daily time spent on the internet. Survey model, one of quantitative research models, was used in this study. The sample this research is 154 science teacher candidates studying at a state university in eastern Turkey. In this research, Individual Innovativeness Scale has been used as a data collection tool. It was observed in the study that majority of science teacher candidates are individually innovative at medium level and that they could be placed in the category of “questioning” people as far as their individual innovativeness are concerned. As a result of this research, it is seen that male teacher candidates are more resistant to innovations compared to female ones. Moreover, it has been observed in the study that reception or lack of preschool education did not have an impact on the individual innovativeness, and that the more time teacher candidates spend on the internet, the less their individual innovative levels are.

Tatort infektiologischer Fall – mit Diagnostik auf Spurensuche: Überlegungen zu Indikationen und Limitationen gebräuchlicher mikrobiologischer Nachweismethoden
Authors: Schöbi Nina , Duppenthaler Andrea
Published: March 2023

Die diagnostischen Möglichkeiten in der Infektiologie haben in den letzten Jahren vor allem durch molekulargenetische Nachweismethoden eine Erweiterung erfahren. Bei der Abklärung von Infektionskrankheiten haben die unterschiedlichen Analysen ihren Stellenwert, wenn diese mit der richtigen Fragestellung zum richtigen Zeitpunkt erfolgen. Jedoch ist nicht jeder positive Befund automatisch auch klinisch relevant beziehungsweise diagnostisch verlässlich. Bei der Beurteilung von Resultaten sind die Grenzen der jeweiligen Analysen zu berücksichtigen. Anhand eines Fallbeispiels einer Patientin mit ‘Fieber ohne Fokus’ sollen im Folgenden Vor- und Nachteile häufiger diagnostischer Methoden in der Infektiologie diskutiert werden.

Aim. To analyze the success rate and other intraprocedural parameters of implantation His bundle pacing lead using different approaches.Methods. Since 2018 to 2022 we have tried His bundle lead implantation in 32 pts. During implantation 4 different approaches were used: on-stylet in 6 pts (19%), on-stylet over the delivery tool in 9 pts (28%), over the C304 SelectSite (Medtronic, USA) delivery tool in 10 pts (31%), over the modified C304 SelectSite delivery tool in 12 pts (37%).Results. Four studied implantation approaches did not differ by means of procedure duration as well as lead parameters. The success rate of implantation using modified C304 SelectSite delivery tool was higher than using other 3 techniques (91,7% vs 44%, p-0,006).Conclusion. His bundle lead implantation success depends significantly on chosen implantation technique.

Colorectal cancer ranks third after breast cancer in terms of incidence and second after lung cancer in terms of mortality.

Management of rectal cancer requires a multidisciplinary approach, with the surgical management playing the main role. There are currently three resective techniques that complement the traditional open surgery: laparoscopic surgery, robotic surgery, and transanal total mesorectal excision.

Rectal cancer in elderly patients is particularly hard to diagnose and treat surgically due to multiple comorbidities and limited functional reserve. Treatment of such patients may be associated with poorer outcomes after both open and minimally invasive surgery.

This article reviews the current state of advances in minimally invasive surgery for rectal cancer in general and in elderly patients in particular.
Can We Detect Peritoneal Adhesions With MRI and CT Prior to Abdominal Surgery?

This article is part 2 of our review assessing diagnostic modalities. In the first part, we analyzed the ultrasonography capabilities to detect abdominal adhesions. The second part assesses the effectiveness of MRI and CT.

MRI and CT modalities are much less commonly used in detecting adhesions than ultrasonography. MRI has approximately the same prognostic capabilities as ultrasonography in detecting adhesions between the viscera and the abdominal wall, and it additionally detects adhesions between the abdominal organs. Yet, MRI is significantly more time-consuming and highly dependent on the radiologist experience. Like ultrasonography, MRI determines the extent of adhesions but not the type.

Native CT does not visualize abdominal adhesions, though its findings in artificial pneumoperitoneum are superior in diagnostic value to those of ultrasonography and MRI, so this modality should be considered.
