Published: April 2024

Objectives: To evaluate the significance of advanced machining techniques, such as EDM, ECM, and USM, in increasing productivity and overcoming challenges associated with outdated Al-SiC MMC machining. To assess the surface roughness, tool wear, and machining cost implications of employing advanced machining methods for Al-SiC MMCs. Methods The parameters studied were voltage (V), feed rate (F), and electrolyte concentration (C) in electrochemical machining (ECM) of Al/15%SiC composites. To optimise process parameters, the Taguchi method for Design of Experiments (DOE) with an L27 orthogonal array was used. Signal responsiveness is optimised using the Taguchi approach. The Technique for Order Preference by Similarity to the Ideal Solution (TOPSIS) is used to find optimal machining settings. Findings: The outcome of this research is that the parameters affecting surface roughness and material removal rate are voltage, electrolyte concentration and feed rate. The minimum Surface Roughness achieved by selecting the best combination level is A2, B3, C3 (smaller is better) i.e., voltage 20 V, feed rate (f) 0.4 mm/min., electrolyte concentration (c) 30 g/lit. The maximum Material Removal Rate achieved by selecting the best combination level is A3, B3, C3 (larger-is-better) i.e., voltage 25V, feed rate (f) 0.4 mm/min., electrolyte concentration (c) 30 g/lit. Novelty : In this work, TOPSIS technique paired with Taguchi method is used which is rarely studied by other researchers. TOPSIS technique provides the best optimal solution as compared to other techniques. Keywords: Al-SiC MMCs, ECM, MRR, Ra, Taguchi method, TOPSIS

Authors: Pertsev N.V. , Bocharov G.A. , Loginov K.K.
Published: April 2024

A mathematical model describing the initial period of spread of HIV-1 infection in a single lymphatic node of an infected individual is presented. The model variables are the quantity of viral particles, CD4+ T-lymphocytes, and antigen-presenting cells. To build the model, a high-dimensional system of differential equations with delay, supplemented initial data, is used. Some of the model equations take into account intermediate stages of development of viral particles and cells involved in the infectious process. The existence, uniqueness and non-negativity of the components of the model solutions on the semi-axis for non-negative initial data are established. Conditions for the asymptotic stability of the equilibrium state interpreted as the absence of HIV-1 infection in the lymphatic node are obtained. To solve the model numerically, a semi-implicit Euler scheme is used. The conditions for the attenuation of HIV-1 infection in the lymphatic node and the beginning of the systemic spread of infection throughout the organism of an infected individual are analyzed analytically and numerically.

Protean Career Orientation and Organizational Commitment: The Role of Organizational Identification
Authors:   People & Global Business Association, d d
Published: April 2024

Purpose: This study investigates the effect of individuals’ protean career orientations on their organizational commitment. We expected protean attitudes to be positively related to organizational commitment, based on the perspective that protean career orientation could increase the sense of organizational identification.
Design/methodology/approach: We targeted permanent employees from various industries. The survey was conducted through a website, and a total of 572 employees participated in the survey. For analysis, structural equation modeling was used.
Findings: The results show that protean career orientation is positively related to organizational commitment, and this relationship is fully mediated by organizational identification. Specifically, affective and normative commitment were positively influenced by protean career orientation, being mediated by organizational identification. Only continuance commitment did not show any relationship with the protean attitude.
Research limitations/implications: Despite elucidating the process of mediating, this study limited the variable to organizational identification. The results of this study suggest that more diverse variables (e. g., personality, ideology, values) and approaches (e. g., moderated mediation model) could be investigated in the area of protean career orientation.
Originality/value: The results are contrary to previous speculations that protean people are self-centered with insufficient commitment toward the organization. In particular, the positive relationship between protean career orientation and organizational identification is newly suggested, providing a possibility for redefining the core values of protean careers and their potential.

Published: April 2024

Titanium dioxide nanoparticles со-doped with tin and sulfur were studied in the concentrations of 1, 2, 3, 4, and 5 at.% of Sn. The processes of thermal effects on samples and the colorimetric characteristics of thin films obtained from the samples are considered. A color change is noted upon doping, with a transition from white to pale yellow. There is also a noticeable decrease in the mass of the samples during annealing until a temperature of 517 °C is reached, then the mass remains unchanged. The differential thermal analysis curve in this temperature range shows exothermic and endothermic peaks associated with the doping process. The color characteristics are determined and the influence of doping elements on them and the connection with photocatalytic activity are shown.

Seismological Ground-Motion Models for Generic Hard-Rock Site Condition in Western Canada
Authors: Hassani Behzad , Atkinson Gail M. , Fairhurst Mike , Yan Li
Published: April 2024

We develop ground-motion models (GMMs) to characterize the Fourier amplitude spectrum (FAS) for earthquakes in British Columbia (B.C.), Canada. GMMs developed for FAS are useful for understanding the underlying seismological parameters and can be transformed into GMMs for response spectral values for other applications (e.g., probabilistic seismic hazard analysis [PSHA]). The GMMs are calibrated using a compiled FAS database, referenced to a B.C. generic hard-rock site condition (shear-wave velocity ∼2285 m/s). The GMMs are developed separately for crustal, in-slab, transition, offshore, and Haida Gwaii events. The GMMs are calibrated using data mostly from M 2.5 to 5.5 earthquakes recorded at rupture distances of ∼50 to 500 km. Outside this range, the models are constrained by a seismological model supplemented with sparse observational data. The amplitude decay rate for crustal earthquakes in B.C. is very similar to that given by the empirical model of Bayless and Abrahamson (2018; hereafter, BA18), developed from California data on soil sites. However, we observe magnitude- and frequency-dependent differences between the models for ground-motion amplitude levels. We attribute these to (1) the different reference-site conditions of the models, with the B.C. GMMs being referenced to hard rock, and (2) steeper magnitude scaling at small-to-moderate magnitudes for events in B.C. in comparison to the BA18 model.
Cyclic Injection Leads to Larger and More Frequent Induced Earthquakes under Volume-Controlled Conditions
Authors: Kroll Kayla A. , Cochran Elizabeth S.
Published: April 2024

As carbon storage technologies advance globally, methods to understand and mitigate induced earthquakes become increasingly important. Although the physical processes that relate increased subsurface pore pressure changes to induced earthquakes have long been known, reliable methods to forecast and control induced seismic sequences remain elusive. Suggested reservoir engineering scenarios for mitigating induced earthquakes typically involve modulation of the injection rate. Some operators have implemented periodic shutdowns (i.e., effective cycling of injection rates) to allow reservoir pressures to equilibrate (e.g., Paradox Valley) or shut-in wells after the occurrence of an event of concern (e.g., Basel, Switzerland). Other proposed scenarios include altering injection rates, actively managing pressures through coproduction of fluids, and preinjection brine extraction. In this work, we use 3D physics-based earthquake simulations to understand the effects of different injection scenarios on induced earthquake rates, maximum event magnitudes, and postinjection seismicity. For comparability, the modeled injection considers the same cumulative volume over the project’s operational life but varies the schedule and rates of fluid injected. Simulation results show that cyclic injection leads to more frequent and larger events than constant injection. Furthermore, with intermittent injection scenario, a significant number of events are shown to occur during pauses in injection, and the seismicity rate remains elevated for longer into the postinjection phase compared to the constant injection scenario.

Gestión y conservación de la pesca y el criterio de precaución
Authors: De Sadeleer Nicolas
Published: April 2024

En la medida en que el estado de las poblaciones depende de la calidad del medio marino, salvaguardar la biodiversidad es una de las condiciones sine qua non de la sostenibilidad económica de la pesca. Por supuesto, la política pesquera es el ejemplo arquetípico de política pública dependiente del medio ambiente. La sobrepesca es la principal amenaza para el futuro económico del sector, ya que conduce a una disminución de las poblaciones de peces. El Acuerdo de 1995 de las Naciones Unidas sobre las Poblaciones de Peces fue el primer acuerdo pesquero internacional que consagró el concepto de precaución. La pesca es también una actividad importante dentro de la UE, tanto en términos de explotación de los recursos naturales como de empleo, sobre todo en las zonas costeras donde hay escaso crecimiento económico. Durante mucho tiempo, la Política Pesquera Común (PPC) ha sido una de las más integradas de la Unión Europea. La PPC ya no puede ser concebida como una política sectorial autónoma, sino que debe analizarse en relación con las demás políticas llevadas a cabo por la Unión, en especial, la medioambiental. En el mismo orden de ideas, de conformidad con el principio de precaución consagrado en el apdo. 2 del art. 191 del Tratado de Funcionamiento de la Unión Europea, la PPC consagró en 2013 un criterio de precaución. El artículo muestra hasta qué punto la política pesquera, a escala internacional y en el derecho derivado de la UE, incorpora el criterio de precaución.
Wola and wolność in Polish
Authors: Dziwirek Katarzyna
Published: April 2024

W artykule zostały zanalizowane powody, dla których w języku polskim powstał termin wolność,
mimo że istniały dwa inne słowiańskie prasłowa o podobnym znaczeniu: swoboda i wola.
Autorka artykułu uważa, że słowo to było potrzebne z powodu zmian semantycznych swobody
i woli, a jego ostateczne znaczenie ukształtowało się na podstawie pozalingwistycznych uwarunkowań
geopolitycznych. W języku polskim prasłowiańska wola z czasem zaczęła oznaczać
głównie intencję, natomiast swoboda – lekkość, łatwość, brak skrępowania, brakowało więc
słowa, które jednoznacznie odnosiłoby się do koncepcji autonomii, niezależności itp. Również
zmiana znaczenia woli sprawiła, że przymiotnik wolny, który choć stworzony od tego samego
rdzenia, od zawsze znaczył ‘autonomiczny’, a nie ‘wolicjonalny’, potrzebował korespondującego
rzeczownika. Wydarzenia historyczne (rozbiory, wojny) spowodowały, że z czasem wolność
zaczęła nabierać znaczenia narodowej suwerenności i nezależności. Artykuł jest oparty na badaniach
korpusowych.
The Grand (Ducal) Finale
Authors: Cantell Sointu
Published: April 2024

The San Lorenzo Basilica in Florence is renowned for its Medici-infused Renaissance program, but there is a lesser-known phase of the Medici family's history in the basilica that unfolded in the 18th century. Between 1738 and 1743, Anna Maria Luisa de' Medici, the last surviving member of the Medici line, oversaw extensive architectural and decorative interventions within the San Lorenzo complex. Her efforts to maintain the cultural heritage of her ancestors were heavily shaped by the imminent end of the Medici bloodline and the difficult transition of the Grand Duchy of Tuscany to the House of Habsburg-Lorraine.

This article explores Anna Maria's motivations for her elaborate renovation projects in the basilica, with a particular focus on two of her most notable commissions: Vincenzo Meucci's cupola fresco in the nave of the basilica and the new bell tower designed by architect Ferdinando Ruggieri. These two projects, the only ones completed by Anna Maria before her death, demonstrate her ambitions within the San Lorenzo and help to uncover several underlying premises for their conceptions.

Theoretical Approach by DFT in the characterization of the Zn(II) Benzoate
Authors: Almeida Patrícia Saraiva Vilas Boas de , Baia Vitor da Cunha , Maia José Roberto da Silveira , Alvarenga Elson Santiago de
Published: April 2024

The condensation reaction between aminoguanidine bicarbonate and benzoic acid produced 1,2,4-triazole which, after reaction with zinc(II) chloride, led to the formation of a complex, Zn(II)-1,2,4-triazole. This complex decomposes into chloroform leading to the formation of a by-product identified by multinuclear NMR (13C and 1H) as zinc(II) benzoate. Subsequently, a theoretical study, using the Hartree-Fock and DFT methods, was applied to validate zinc(II) benzoate as a byproduct of decomposition through the calculation of the magnetic shielding tensor (NMR), as well as to address some structural characteristics of this compound since zinc compounds present a variety of geometric arrangements and coordination numbers. The theoretical result showed that Zn(II) benzoate is the by-product of the reaction and that it dimerizes in chloroform solution.
INFLUENCE OF THE GRAIN CARGOES CHARACTERISTICS ON THE CHOICE OF WAREHOUSE EQUIPMENT OF THE PORT’S CARGO TERMINAL

Published: April 2024

The modern features of transportation and storage of grain cargoes in conditions of military aggression and changes in transport supply chains is considered in the article. Agriculture is one of the most important sectors of the domestic economy, which provides food not only for our country, but is an important element of global food security. Ukraine is one of the five world leaders in grain exports. Before the war, the total capacity of the country's grain storage facilities was approximately 58 million tons, and during the first six months of the war 15.7 % Ukrainian grain storage facility was destroyed, damaged, or came under the control of the occupiers. The blockade of the Black Sea ports forced farmers to look for new ways to export grain. Unfortunately, neither the western borders nor the Danube ports were unprepared for such a huge cargo flow. The destruction of transport and storage infrastructure requires huge risky investments from farmers, which prompts them to look for new innovative ways of transportation, storage and transshipment of grain cargoes. The emergence of a significant cargo flow of grain cargoes in the Danube region contributed to the transformation of the region from depressed (as it was recently) to attractive for investment. Making huge investments in the construction of new grain terminals turned out to be quite risky, from the point of view of ensuring security and competitive advantages. In this regard, the work considers innovative technologies of transportation, storage and transshipment of grain cargoes using flexible containers, which allow to deliver grain cargoes «door to door» without additional technological operations. A flexible container protects grain cargo from adverse weather conditions, preserves the quality of the cargo, greatly simplifies the transshipment process and is a universal means of transportation by any type of transport.

Aim: This study aimed to investigate the role of beta human chorionic gonadotropin (beta hCG) levels on post embryo transfer (ET) 12th- and 14th-day, and its folding after 48 hours in predicting live birth, abortion, and biochemical pregnancy.
Material and Methods: The study included 124 patients who had a positive pregnancy test after a fresh single day 3 ET at the in vitro fertilization (IVF) center between 2017 and 2021. The first beta hCG value was measured 12th day and the second 14th day after ET. The beta hCG fold was calculated by dividing the second beta hCG value by the first beta hCG value.
Results: The patients' IVF indications included unexplained (n=40, 41.1%), poor ovarian reserve (n=23, 25.0%), male factor (n=31, 29.8%), and tubal factor (n=3, 4.1%). Of the 124 patients, 97 (78.2%) had a fetal sac, 81 (63.5%) had a fetal heartbeat (FHB), and 70 (56.5%) had a live birth. The results indicated that the post-ET 14th-day beta hCG level was the best predictor of biochemical pregnancy. It has a high sensitivity (92.5%) and specificity (86.6%), with an optimal cut-off value of 175 U/L. The post-ET 14th-day beta hCG level was the best predictor of a live birth. The post-ET 14th-day beta hCG value of 214.5 U/L had an 82.7% sensitivity and 74.4% specificity to predict the FHB.
Conclusion: The beta hCG value, measured between the 12th and 14th days after ET, as well as the folding rate on these two days, can provide information about the pregnancy progression.

Access to health is a human right [1, 2]. Part 1 of Article 25 of the Universal Declaration of Human Rights stipulated that everyone has “the right to a standard of living adequate for the health and well-being of himself and of his family” [3]. To ensure access to health by everyone requires a high level of creativity in developing processes with potential to reach places where motor vehicles and similar expensive technologies cannot reach [4]. Viable alternatives remain unclear without firm leadership in addressing inadequate access to health of the poorest populations [5].
Women’s NutriBusiness Cooperatives in Kenya – A Prologue
Authors:   The Pennsylvania State University, USA, Maretzki Audrey
Published: April 2024

My last visit to Kenya in the role of Principal Investigator for the USAID-funded University Development Linkage Project was in December, 1999 when the University of Nairobi, Tuskegee University and The Pennsylvania State University formally transferred the assets of the nutribusiness project to the women’s cooperatives in Gatanga and Ndanai. The turning-over ceremonies were attended by cooperative shareholders and officers, members of the Kenyan parliament and other local dignitaries as well as by USAID staff and representatives from the participating universities. Expectations of success as the project ended were high on the part of the women who had come to understand that the uji mixes they had created using crops they grew on their shambas were not only tasty but also healthful foods for babies and young children.

This paper considers the role of professional societies and networks in building capacity for improved nutrition through cohesion with relevant national institutions and development partners on issues of food and nutrition policy development, implementation, and monitoring. It draws heavily on practical experience and capacity of professional members of the Uganda Action for Nutrition (UGAN), a corporate agency and society that advocates for adequate nutrition for all in Uganda. UGAN evolved from a United States Agency for International Development (USAID) effort, to a Ugandan owned and managed initiative that provides a forum to advocate for adequate nutrition for all through all channels of policy and leadership. In effect, UGAN activities are geared towards improved productivity and realisation of high quality nutrition advocacy messages and actions to influence positive development outcomes. The outputs provide options for improving the food and nutrition security and livelihoods of vulnerable groups in Africa and other parts of the world through its membership and participation in the activities of the International Union of Nutrition Sciences (IUNS), and partnerships with other development actors. With a membership of diverse professional levels and disciplines, UGAN provides a diversity of well tailored nutrition strategies through multidisciplinary channels that directly and positively affect vulnerable populations, and lead to demand-led development initiatives. This initiative can assist the achievement of a technical–social empowerment balance in alleviating malnutrition. Lessons learned from the transparent and participatory leadership, are pulled out to provide recommendations for achieving positive and sustainable development outcomes through food and nutrition security interventions.

In January 2011, the Public Health Advocacy Institute of Northeastern University, School of Law in collaboration with Professor Ruth Oniang’o and the Institute for Legislative Affairs, convened a roundtable discussion on integrating the human rights based approach and the Millennium Development Goals to Kenya’s Tobacco Control efforts. These two interrelated approaches are potentially powerful tools of tobacco control in Kenya.
Who will feed Africa tomorrow?
Authors:   African Journal of Food, Agriculture, Nutrition and Development, Oniang'o Ruth
Published: April 2024

The above is an important question that needs debate and I can see the issue is beginning to attract attention in certain quarters. From the time I got involved in Rural Development work, nearly 2 decades ago, I did realize that in most of Africa, it was women who were toiling away for the sake of their families. The role of feeding families had changed. Men, instead of working to provide for their families’ food security, were now bystanders and job seekers in towns, leaving their women folk to struggle to produce food from land they did not own, and without the requisite support such as extension knowledge, appropriate inputs or available credit to help prepare the land and plant in a timely manner.
The role of the youth in enhancing food security: The untapped potential
Authors:   University of Nairobi, Ooko George
Published: April 2024

In the recent past youth leadership and empowerment is indeed gaining momentum in the development agenda of many governments and international development organizations. The fact that key organizations such as the African Union’s Commission, United States Agencies and the United Nations have initiated programs to build youth capacities for quality and meaningful participation in development and decision making processes, means that the issue deserves serious attention by all [1]. Investing in youth development has been shown to have the potential to yield greater economic growth and social well-being, not only for today but also for the future.
Air Warfare over Ukraine and International Humanitarian Law
Authors: Sotula Oleksandr , Piątkowski Mateusz
Published: April 2024

The Russian aggression against Ukraine involves extensive use of air power, proving that without the sufficient level of air control, the combat operations on the ground face significant operational challenges. The use of air power raises questions regarding the legality of the aerial actions conducted over Ukraine. This conflict in the air domain is characterised by separate campaigns. The first one was a battle over the air superiority of Ukraine, which was relatively short in time (February–April 2022), albeit intense, and lost by the Russian Air Force due to the inability to destroy Ukrainian air defence assets and Ukrainian military aviation. The second one, still in progress at the moment this article is being written, looks to become an unresolved contest of attrition, as both belligerents vastly increased their air disruption capabilities. In particular, during the last period of the first phase, it is believed that many of the Russian air strikes were, in fact, indiscriminate or deliberately directed against civilian objectives. The aim of the article is to analyse the overall conduct of the air war over Ukraine and pinpoint the legal challenges in assessing the legality of such air operations. In the context of available information, the paper will seek to understand the legal framework concerning the destruction of the An-225 at the Hostomel airport during the first phase of hostilities, the use of certain aerial weapons, and the selection of targets.
Accountability for the Crimes Against Civilians Committed During the Armed Conflict in Ukraine
Authors: Głogowska-Balcerzak Anna
Published: April 2024

The article explores the question of crimes committed against the civilian population during the war in Ukraine and the possible ways of bringing to justice those responsible. A full-scale aggression launched by Russia has caused death and widespread suffering of thousands of Ukrainian civilians and combatants. The article focuses on the events following 24th February, 2022, bearing in mind that the conflict had started much earlier – with the illegal annexation of Crimea and the beginning of fighting in eastern part of the Ukraine in 2014. After introductory remarks in the first section, the second part of this article will be focusing on different acts constituting war crimes that were committed during the war in Ukraine, and the third part will address existing accountability mechanisms and briefly discuss the advantages and disadvantages of each of them.
War as an Accession Accelerator? Ukraine’s Path Towards the EU
Authors: Mazur Sylwia Katarzyna
Published: April 2024

The European Union’s response to the war in Ukraine is perceived as swift and relatively coherent. The political willingness to support its attacked neighbour has also extended to Ukraine’s membership bid. Despite protracting war and worsening Ukraine’s position, there are no doubts over the state’s commitment to reforms. For now, it can be safely assumed that Ukraine will pursue its path towards membership. Can fighting war and pushing an arduous accession process be balanced by the political will of the EU Member States rooted in a wartime gesture of solidarity?
