En Argentina, los juicios de lesa humanidad han estado signados por el debate en torno a su divulgación pública desde sus inicios durante la apertura democrática en la década de los ochenta, hasta nuestros días.  Sin embargo, con la llegada de la pandemia en marzo de 2020 se dio la apertura a una nueva etapa en relación a los vínculos entre medios y justicia penal durante el desarrollo de los juicios de lesa humanidad. En este artículo nos proponemos analizar las reconfiguraciones, así como las continuidades, discontinuidades, tensiones y pujas en torno a la dimensión comunicacional de los juicios de lesa humanidad, durante un singular período de virtualización de la justicia en medio de la crisis sanitaria por la pandemia por COVID-19. A través de un trabajo de campo con metodologías de la etnografía digital, tuvimos por objetivos reconstruir las primeras demandas y discusiones que desembocaron en el reinicio de los juicios; conceptualizar las distintas modalidades tecnológicas del desarrollo de los juicos de lesa humanidad a nivel nacional y los canales mediáticos por los cuales se garantizó el principio de publicidad en los distintos tribunales; y reflexionar en torno a las principales resistencias e innovaciones de este proceso que aun habiendo finalizado la pandemia continua desarrollándose a través de canales digitales.

Authors: Gonzalez Liara M. , Stampley Anita R. , Marcellin-Little Denis J. , Kedrowicz April A.
Published: August 2023

OBJECTIVE

To objectively measure the current demographic makeup of the American College of Veterinary Surgeons (ACVS) diplomates and to develop a survey tool to be used as a metric to measure future changes in the ACVS demographic profile.

SAMPLE

737 ACVS diplomates.

METHODS

A 14-item electronic survey was sent to 2,199 ACVS diplomates between August 25 and September 9, 2021, via email. Survey items included demographic information as well as perceptions about the ACVS and diversity, equity, and inclusion (DEI). Responses were quantitatively and qualitatively analyzed.

RESULTS

The survey response rate was 34% (737/2,199). The median age category among respondents was 45 to 54. The median years in practice as a diplomate was 11 to 15. The majority of respondents identified as white/Caucasian and heterosexual, with male and female respondents being similarly represented. Most respondents identified English as their first language. Few considered themselves first-generation college graduates or identified as disabled. Many respondents considered DEI to be an important initiative to promote in the ACVS.

CLINICAL RELEVANCE

Findings suggested that the majority of ACVS respondents are supportive of DEI efforts. This study also serves as an objective analysis that can be reassessed in the future to determine the success of such initiatives.
Unveiling management trends in the public sector: A literature review and research agenda
Authors: Santos Márcia R. C. , Laureano Raul M. S.
Published: August 2023

Scholars and practitioners have, for many decades, sought to address management issues related to public sector policies. This study examines the academic research on this sector focused on these topics by conducting an automated computer analysis of 17,928 documents indexed in Scopus and published between 1950 and 2021. Six clusters were identified within this literature: economic growth during crises, reforms for the future, human relations, successful practices, partnerships and public banking services. This study thus systematises the lessons learned over the past decades, thereby contributing to governments’ ability to design public policies to meet future challenges and providing tools for dealing with the current coronavirus disease-19 pandemic.
Zonal Concept: Landscape Level Parameters and Application
Authors: Dujka Petr , Kusbach Antonín
Published: August 2023

Zonal concept is a traditional approach in land assessment. Although its principles have been known for over a hundred years, they have not yet been thoroughly evaluated using modern analytical approaches. Assessing the empirically established parameters for characterising a zonal site, establishing threshold values of significant environmental factors, along with assessing the applicability of the zonal concept, were the goals of this study. The data analysed were obtained from the robust and objective Czech National Forest Inventory database. Regression, indirect ordination, hierarchical clustering and spatial analyses of geo-information systems were used. The study revealed seven crucial environmental factors: Slope, Slope Height, Terrain Surface Texture, Negative Openness, Multi-Resolution Index of Valley Bottom Flatness, Soil Type and Soil Subtype. A graphical model of zonal/azonal sites was constructed based on calculated threshold values of the factors. This methodic approach introduces significant geomorphological information that are otherwise problematically detectable in field mapping. We suggest it is possible to use the zonal concept as a base layer for general landscape assessment. Zonal site classification can become a part of a precise land management practice, consisting of valuable empiricism of traditional landscape ecological classifications enriched by modelling in disturbance ecology and prediction of climate change effects.

Authors: MARUMAHOKO Sylvester , NGORIMA Obey , SHAYAWABAYA Roseline
Published: August 2023

It can be argued that nursing professionals are the backbone of any healthcare system. The article grappled with the question of why nurses are resigning from Chitungwiza Central Hospital (CCH) in large numbers to the point of nearly crippling public healthcare service delivery at Harare’s dormitory town situated 30 kilometres from the capital. Using survey methodology and application of SPSS, the study sought to identify both the root causes and possible solutions (retention strategies) for addressing the resignation of nursing professionals at CCH. Better remuneration, a safe work environment, increased internal communication, recognition and fulfilment of professional ambitions are some of the solutions identified through survey research for addressing the problem of resignation of nurses in large numbers.
EMOTIONAL INTELLIGENCE AND ACADEMIC ACHIEVEMENT. A STUDY AMONG UNIVERSITY STUDENTS FROM PUBLIC ADMINISTRATION PROGRAMS
Authors: NICA Elvira , SABIE Oana Matilda
Published: August 2023

In recent years the interest in emotional intelligence within scientific literature has grown, but too little has been written about the influence of emotional intelligence within educational systems, especially the relation between emotional intelligence and teachers’ job performance, or emotional intelligence and students’ academic achievement. Universities around the world have experiencing changes and reforms, impacting the teachers’ job performance and academic achievement among university students. Emotional intelligence plays an important role in many areas of our lives. The scope of the research is to investigate the impact of emotional intelligence on students’ academic achievement from public administration programs. We choose students from public administration, since they are supposed to work after graduation in public institutions, and get in direct contact with citizens. At the level of Romania, there is no study with predictive value regarding the “impact of emotional intelligence on students’ academic achievements” supported by empirical research. Regarding the methodology, we collected data using the questionnaire which was developed based on the instruments by previous researchers. Respondents were students from public administration programs. The benefits of such a study are to provide a solid basis for understanding the mechanisms of emotional intelligence (EI) and their role in determining or sabotaging academic achievement. The effect of emotional intelligence on students’ academic achievement was established. On the basis of the findings, it is suggested that emotional intelligence should be integrated into university students’ curriculum. The study further advocated for the promulgation of educational policy on emotional intelligence. Also, this research will represent an important contribution to the Romanian and international literature, both in the field of emotional intelligence, as well as in the field of students’ academic achievement and continuous students’ personal development (academic self-efficacy).

Published: August 2023

Oil palm empty fruit bunches (OPEFB) is one of the palm oil industry solid wastes that can be used as an alternative material to product composites. This research was conducted to determine the effect of the addition of Zinc Oxide (ZnO) as a filler material hybridized with OPEFB fiber to the flexural strength of polymeric foam composites. The aim of this research is to obtain the strength of the flexural test value of the composite material polymeric foam reinforced OPEFB fiber and Zinc Oxide (ZnO) with reference to the ASTM D790-92 standard. The composition of the specimens are 70% Resin, 15% OPEFB Fiber, 15% Polyurethane with different fiber sizes namely mesh (40, 60, 80, 100) and the addition of Zinc Oxide (ZnO) of (0%, 5%, 10%, 15%, 20%). The test specimen used for each composition is 5 samples, so that the entire test sample is 100 samples. From the test data it can be concluded the value of flexural strength in the 100 mesh OPEFB specimens and the addition of Zinc Oxide (ZnO) 10% is the best composition compared to 40, 60 and 80 mesh OPEFB with the addition of Zinc Oxide (ZnO) 5%, 15%, and 20%, where the voltage value is 10,01141 MPa and the strain value is 0,898456 mm / mm. From the research data it can also be concluded that the smaller the OPEFB fiber size with the addition of zinc oxidation (ZnO) 10%, the flexural strength of the polymeric foam composite material will be better.

Authors: Lostari Aini , Susastro Susastro , Machfuroh Talifatim
Published: August 2023

Pellet machine is a machine used to print feed in the form of pellets. In this machine, if it operates, it can experience excessive vibration and the force acting on the machine is close to its natural frequency and can cause damage, so it needs to be reduced. In this study, the objective of this research is to model and simulate vibrations in the gearbox and grinder to determine the results of the displacement and acceleration vibration responses on the pellet machine. In this study, an electric motor is used as a source of rotation and an input clutch as a connection between the shaft of the electric motor and the gearbox as a transmission to reduce the speed of the electric motor, where the rotation produced by the electric motor contains vibrations, the output coupling is the connecting shaft between the gearbox shaft and the shaft grinder and miller as a tool used to print pellets. From the existing physical form, mathematical equations and simulation blocks are constructed. In this research, it is found that the vibration response generated from the gearbox and grinder can be modeled with the x and z axes as the center of the system. The higher the vibration response, the higher the given frequency, the greater the amplitude and rms of the displacement and acceleration responses in each part, namely the motor, clutch in, gearbox gearbox, coupling out, and grinder will be greater. The result of displacement vibration response yields an rms of 1.956. The worm gear in the gearbox produces a displacement vibration of 1.0585 m and an acceleration of 6.8485 m/s2. The mill produces a displacement vibration of 1.0891 m and an acceleration of 5.1095 m/s2.

Ubuntu: An Underutilised Foundational Constitutional Principle of South African Environmental Law
Authors: Dube Felix
Published: August 2023

This article uses the doctrinal legal research method to examine how ubuntu, the indigenous value of humaneness, can serve as a foundational constitutional principle of South Africa’s environmental law and governance framework. It argues that ubuntu has a role to play in the re-imagination of humanity’s relationship with the environment, particularly when its building blocks are embedded in law to address the deep socio-ecological crisis of the Anthropocene and when applied alongside conventional and customary principles of environmental law, such as the no-harm rule, the precautionary principle, the principle of prevention, intergenerational equity and sustainable development. In South Africa, ubuntu already enjoys judicial recognition as a foundational constitutional principle. Its moral and normative force offers an alternative foundation to build a stronger environmental law framework that can protect the vulnerable living order. In this article, the basic proposal is that ubuntu is an underutilised constitutional principle that could be applied by South African courts to environmental disputes. Its potential in the adjudication of environmental cases emanates from its origins as an indigenous value and from the benefits that foundational constitutional principles generally bring in constitutional and human rights litigation.
Five Decades of the Nuclear Non-Proliferation Treaty: Time to Pass the Baton to the UN Security Council?
Authors: Barrie George Napier
Published: August 2023

The Treaty on the Non-Proliferation of Nuclear Weapons (NPT) came into force in 1970. After renouncing its nuclear weapons programme, South Africa became a party to the NPT in 1991. The NPT is the principal international instrument aimed at preventing the spread of nuclear weapons. The NPT has generated various other treaties with similar aims, which, together with the NPT, constitute the ‘nuclear non-proliferation regime’. The NPT has, for various reasons, not been a success. Whether the NPT has achieved nuclear non-proliferation is a moot point–a concept which implies nuclear disarmament. For example, there is evidence of a network of covert operations marketing nuclear technology; some non-NPT states have clandestinely embarked on nuclear weapons programmes, and some NPT states have threatened to adopt a policy of actual or pre-emptive use of nuclear weapons even against non-nuclear weapons states for its deterrent value. Alarm bells are ringing regarding the interpretation of ‘peaceful’ and ‘non-peaceful’ uses of nuclear energy. Despite the NPT, nothing prohibits the testing and refinement of existing nuclear weapons technology. Certain questions need to be answered. Has the NPT not become an instrument of rhetorical posturing by the five major nuclear weapon states–the ‘Club of Five’? Why has none of the Club of Five given their nuclear weapons up? Where do the Club of Five get the moral authority to declare that introducing new members on the Club is unacceptable? Instead of concentrating on the non-proliferation of nuclear weapons as the NPT does, should there not rather be an emphasis on the total prohibition of all nuclear weapons? It is submitted that a more active role for the UN in nuclear non-proliferation issues be considered. All UN Secretaries-General have made nuclear non-proliferation one of their top priorities. Kofi Annan concluded that the NPT was the victim of insufficient progress in not only nuclear non-proliferation but also nuclear disarmament and that the world was sleepwalking towards a nuclear disaster. The basis for greater involvement of the UN Security Council in nuclear non-proliferation and nuclear disarmament is to be found in the Statute of the International Atomic Energy Agency, the Statute of the NPT, the UN Charter and in Security Council Relations 1540 of 2004 and 1929 of 2010. The argument is put forward that as the Security Council has the legal authority to determine threats to the peace or acts of aggression and make recommendations or decide what measures shall be taken regarding it, utilising that body may be a more meaningful route to follow than the NPT which appears to have reached its sell-by date.
The Contribution of Records Management and Big Data Analytics to the Growth of Businesses: An Analysis of Eastern and Southern Africa Regional Branch of the International Council on Archives (ESARBICA) Region
Authors: Motlhasedi Nna , Porogo Keneilwe
Published: August 2023

This study examines the synergy between digital records management and big data analytics in the Eastern and Southern Africa Regional Branch of the International Council on Archives (ESARBICA) region. The study sought out records management factors that enable big data analytics and determined the major hindrances to the implementation and integration of big data analytics into records management in the ESARBICA region. The study adopted a qualitative research design, based on document analysis on the role of records management and big data analytics in growing businesses, and used a thematic analysis approach for data analysis. Furthermore, the diffusion of innovations theory was used as a theoretical lens guiding the researchers’ viewpoint. This study revealed that big data analytics is still in its infancy in the ESARBICA region. There is no merger of records management and big data analytics to leverage from and optimise business growth. The study recommends an uptake in supporting records management infrastructure to successfully and seamlessly merge records management with big data analytics. The study developed a framework that guides on ways to incorporate records management into big data analytics and to develop a practical solution to the overall management of big data into meaningful digital records. This framework aims to harmonise records management and big data analytics, relying on available relevant ICT infrastructure and regulatory frameworks.
Fourth Industrial Revolution in South Africa: Challenges Confronting Health Care and a Health Care-focused Strategy
Authors: Kabwe Kabaso
Published: August 2023

This article explores challenges in developing a Fourth Industrial Revolution (4IR) health strategy in South Africa against the background of the country’s ailing public health care system, on which around 80% of the population is dependent. This situation presents a problem of inequities in access to health care which, if not addressed, may be made worse as technological innovations increase. As such, a deliberate approach regarding 4IR is essential. The article is a desk research that utilises a qualitative approach by collecting and analysing data from various secondary sources in both published and unpublished literature. It considers theoretical literature on policy formulation, design and tools, as well as literature on the challenges of the country’s health system. The article finds that while there is a need for a 4IR health-focused policy, the South African state of health makes it a challenge to do so. Access to and implementation of the 4IR in the health sector need greater engagement with the problems in health care, as opposed to the implementation in a developed world. Further, until the NHI is fully implemented, a 4IR health strategy may not only be difficult to formulate, but to implement as well. The article contributes to the scholarship on policy formulation in South Africa and identifies the key features of what a South African health-focused 4IR strategy may contain. It further helps us to appreciate the challenges that confront an African health care system, particularly in view of the 4IR.
Methods of Processing Medicinal Plants: A Semantic Study of the Use of Verbs in Sesotho Sa Leboa
Authors: Tembane Seleka
Published: August 2023

From time immemorial, medicinal plants have been common traditional medicines for treating diseases and ailments in most households. Even today, plants are used for treating ailments and diseases such as the flu and coronavirus disease 2019 (COVID-19). This article investigates the semantic use of verbs for collection, preparation and administration as methods of processing medicinal plants in Sesotho sa Leboa. Most of the medicinal plants, like folktales, are extinct, so by writing this study the ethnobotanical knowledge of the communities will be promoted and preserved. Medicine from medicinal plants is mostly used in a traditional medical healthcare system. Recent studies have indicated how the medicinal plants form the foundation of traditional medicine and how these are sometimes incorporated into allopathic or biomedical medicine. For the medicinal plant to attain its medicinal value, several processes take place and verbs are used to describe them (processes). Specific meaning is attached to the verbs of methods used during the collection, preparation and administration of medicinal plants. Ethnobotanical theory forms the framework of this article, supported by the theory of linguistics. A qualitative approach is used to explain concepts in the collection, interpretation and analysis of data. Data is collected from existing documents and auto-ethnography. The study found that verbs used in the methods of processing medicinal plants are semantically used in relation to specific parts of the plant.
Batswana’s Beliefs, Myths and Practices regarding Certain Birds
Authors: Matjila D S
Published: August 2023

From time immemorial, birds have been considered to represent a variety of symbols, depending on their attributes and behaviour. Birds might epitomise spirituality, life, death, peace or conflict. This article deals with the traditional beliefs, myths and practices of the Batswana regarding certain birds, such as the mmamasiloanoka (hamerkop/hammerhead), kgoadira (fish eagle) tladi (lightning bird), tlhatlhamedupe (Jacobin cuckoo bird), leeba/lephoi (dove), lenong (vulture), legakabe (crow) and morubisi (owl) that feature prominently in their biosphere. The Batswana composed songs, poems, dramas, performances, folktales and proverbs about these birds, contending that religious value can culturally be attributed to the activities of these birds, in so far as their exertions and stories about them concern human experiences such as distress, happiness or strong belief. This research will use a qualitative method to analyse Setswana literature about the birds. The theory of critical discourse analysis is employed to enhance knowledge creation. The study demonstrated that religious value can culturally be attributed to the activities of these birds.
Amorphous aggregates with a very wide size distribution play a central role in crystal nucleation
Authors: Liao Zhiyu , Das Ankita , Robb Christina Glen , Beveridge Rebecca , Wynne Klaas
Published: August 2023

There is mounting evidence that crystal nucleation from supersaturated solution involves the formation and reor-ganisation of pre-nucleation clusters contradicting classical nucleation theory. Here, a wide range of amino acids and peptides is investigated using light scattering, mass spectrometry, and in-situ terahertz Raman spectroscopy to demonstrate that the presence of amorphous aggregates with a wide range of sizes is a general phenomenon in supersaturated solutions. Additionally, these amorphous aggregates act as intermediates for laser-induced crystal nucleation. These observations are inconsistent not only with classical nucleation theory, but also non-classical theories involving liquid-liquid phase separation, requiring a new approach.
Importance of Diffusional Constraints for the Quantitative Evaluation of Calibration Curves of Enzymatic Micro- and Nanoelectrochemical Sensors
Authors: Dannaoui Reina , Yang Xiao-Ke , Huang Wei-Hua , Svir Irina , Amatore Christian , Oleinick Alexander
Published: August 2023

Electrochemical calibration curves recorded at enzyme-modified micro- or nanoelectrodes are often quantitatively analysed using graphical approaches directly derived from the practice widely used in enzymatic analysis when enzymes as well as their substrate and cofactors are homogeneously distributed in the solution. Here, using a simple but highly representative model we demonstrate that this practice yields incorrect interpretation of the experimental results even for a simple Michaelis-Menten mechanism. The present modelling makes it possible to establish the correct relationships linking calibration currents and bulk substrate concentrations by a simple method allowing to take into account the biases due to diffusional constraints. These correct relationships provide kinetic data characterizing a given sensor that ought to be considered whenever a calibrated enzymatic electrochemical sensor is aimed to be used under non-steady state condition, e.g., as for monitoring transient concentration releases of target analytes under in vivo or pseudo in vivo conditions.

Published: August 2023

Efficient and durable catalysis of the oxygen evolution reaction in acidic media remains a grand challenge at the intersection of electrochemistry and materials discovery. Antimony-based rutile oxides have shown great promise but suffer from poor durability at high concentration of activity-promoting elements such as Mn. We use combinatorial methods to realize a new family of catalysts wherein combinations of Sn, Ti, and Sb enable activity in rutile oxides with Mn concentration less than 40%.
Evaluating sentinel pipe racks for monitoring lead release and optimizing corrosion control
Authors: Trueman Benjamin F , Locsin Javier A , Krkošek Wendy H , Gagnon Graham A
Published: August 2023

Orthophosphate can limit lead contamination of tap water, but its benefits are difficult to quantify since lead concentrations are so site-specific. Sentinel homes serviced by lead pipe are ideal for monitoring orthophosphate treatment, but best practices dictate the removal of lead once identified. The best sentinel homes, then, are often short-lived. Here we explore an alternative: recovered lead pipe racks supplied with distributed drinking water at locations throughout a water system. We also propose a strategy for analyzing the data based on the generalized additive model, which approximates time series as sums of smooth functions. Geometric mean lead release from pipe racks exhibited a pronounced dose-response, falling by 54% after an increase from 1 to 2 mg PO4 L-1, and then climbing by 55% after a decrease to 1.5 mg PO4 L-1. Data from nine sentinel homes were consistent with those from pipe racks: geometric mean lead at the high orthophosphate dose was 60% of that at the low dose. Our results demonstrate sentinel pipe racks as a viable alternative to at-the-tap sampling for non-regulatory corrosion control monitoring. They also provide a Bayesian framework for quantifying changes in lead release that can incorporate information from multiple sources.

Dilute to Enrich for Deeper Proteomics: A Yolk-Depleted Carrier for Limited Populations of Embryonic (Frog) Cells
Authors: Pade Leena , Lombard-Banek Camille , Li Jie , Nemes Peter
Published: August 2023

Abundant proteins in biological systems challenge deep mass spectrometry (MS) analysis of the proteome. Yolk, the source of food in many developing vertebrate embryos, complicates chemical separation and interferes with MS signal detection, identification, and quantification. We here report a strategy that enhances bottom-up proteomics in yolk-laden biological systems by diluting out the interferences using a YOlk-DEpleted Carrier proteome (YODEC) via isobaric multiplexing quantification. This mechanism was validated through studies comparing the proteomes of the standard HeLa and South African clawed frog (Xenopus laevis) embryos, where a >90% yolk proteome has historically challenged deep proteomics. The proteome was digested and barcoded before mixing with an isobarically tagged diluent proteome. This diluent carrier was prepared by depleting embryonic tissue of yolk platelets. Compared to the standard multiplexing carrier approach, YODEC more than doubled the detectable X. laevis proteome, allowing for the identification of ~4,200 proteins. Ca. ~80% of the identified proteins were quantified without dropouts in any of the analytical channels. As proof of concept, we applied the strategy to quantify the proteome in cell clones that were isolated from the neurula-stage embryo by dissection or fluorescence-activated cell sorting. YODEC boosted the depth of the measured proteome from ~8,000 cells by 5–15 fold, enabling the detection of molecular adaptors, transporters, translation, and transcription factors. While YODEC was tailored for Xenopus tissues in this study, we anticipate the approach of ‘dilute to enrich’ to also be adaptable to other biological models where abundant proteins challenge the depth of MS proteomics.
Advancements in Cathode Materials for Potassium-Ion Batteries: Current Landscape, Obstacles, and Prospects
Authors: Masese Titus , Kanyolo Godwill
Published: August 2023

The development of advanced energy storage technologies has assumed paramount significance in addressing the escalating demands for sustainable and eco-friendly power sources. Amongst these innovative technologies, potassium-ion batteries (KIBs) have risen to the fore as viable contenders, chiefly owing to their cost-effectiveness and the abundant availability of potassium resources. Nevertheless, the realisation of efficient and high-performance KIBs hinges significantly upon the adept design and appropriate utilisation of cathode materials. Thus, this Perspective provides a comprehensive analysis of the present status, associated challenges, and prospective avenues concerning cathode materials for KIBs. We commence by discussing the significance of KIBs in the context of the global energy landscape and highlight their potential to revolutionise energy storage systems. Subsequently, we delve into cathode materials for KIBs, emphasising their pivotal role in determining the overall performance of these batteries. A systematic survey of the various cathode materials explored to date is presented, primarily encompassing layered oxides, polyanion-based compounds, Prussian analogues and organic moieties. The discussion focuses on the advantages, limitations, and performance metrics of each material class, unveiling the critical insights gained from experimental studies and theoretical investigations. Furthermore, this Perspective sheds light on the prominent challenges and obstacles hindering the widespread adoption of KIBs. These challenges include issues related to limited specific capacities, sluggish kinetics, and performance attenuation during cycling, as well as the scarcity of suitable electrolytes. We offer an authoritative evaluation of the efforts undertaken to address these obstacles, including novel material design strategies, advanced characterisation techniques, and the integration of nanotechnology. Finally, we conclude with a forward-looking perspective, outlining the future directions and potential breakthroughs in electrode materials for KIBs. We emphasise the importance of interdisciplinary collaborations, advancements in computational methods, and fundamental research to foster the development of high-performance and environmentally sustainable KIBs. In conclusion, this Perspective consolidates the current state of electrode materials for KIBs whilst elucidating the challenges that need to be overcome to unlock their full potential. By synthesising the collective knowledge from the latest research endeavours, this Perspective aims to inspire future research and innovation in the pursuit of efficient and scalable KIB technologies.

The goal of the current study was to formulate and evaluate mucoadhesive Dexamethasone beads to significantly lengthen the duration of the drug's stay in the GI system to treat Crohn’s disease. Dexamethasone is a corticosteroid that acts as an anti-rheumatic and anti-inflammatory. To decrease the dosage frequency Dexamethasone adhesive beads were formulated for Intimate contact with the underlying absorption surface is made possible by a prolonged stay at the location, which enhances the drug's therapeutic effectiveness. In the current study, calcium chloride and aluminium chloride were utilised as cross-linking agents to create Dexamethasone mucoadhesive beads employing adhesive polymers like sodium alginate, HPMC, and Eudragit L-100. The prepared beads' entrapment efficiencies ranged from 57.15 to 99.16%. Regarding entrapment effectiveness, particle size, surface properties, and in-vitro drug release experiments, the impact of bioadhesive polymers and cross-linking ions was assessed. The MPS-7 delayed the drug's release for 12 hours, which may be related to the cross-linking agent aluminium chloride. According to drug release kinetics, all of the formulations were more linear concerning zero order (r2=0.99) than concerning first order (r2=0.751 to 0.828). Super Case 2 Transport was discovered to be the precise release mechanism.

Published: August 2023

Research background: The Internet of Things (IoT) is transforming the manufacturing industry by connecting machines, devices, and people to enable intelligent decision-making. However, there is a lack of consensus on the impact of IoT on the manufacturing industry, particularly in terms of its effect on productivity, efficiency, and profitability. Purpose of the article: This study aims to evaluate the impact of IoT on the manufacturing industry by using the Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) method. The TOPSIS method is a multi-criteria decision-making technique that ranks alternatives based on their proximity to the ideal solution. Methods: In this study, we collected data from 50 manufacturing companies that have adopted IoT in their operations. We identified four criteria for evaluating the impact of IoT on the manufacturing industry: productivity, efficiency, profitability, and customer satisfaction. We used the TOPSIS method to rank the companies based on their performance on these criteria. Findings & Value added: The results of our analysis showed that the adoption of IoT has a positive impact on productivity, efficiency, and profitability in the manufacturing industry. In addition, the companies that ranked higher on the TOPSIS method were found to have higher levels of customer satisfaction, indicating that IoT can improve customer experience and loyalty.
(Re)Blurring Coast: Architecture Within the Coastal Threshold of the Waitematā Harbour
Authors:   , Vachias Andre
Published: August 2023

The coast is the threshold between two distinct zones: land and sea. In an island nation, architecture so often finds itself in a position where, through time, it can occupy both. Hence, the architecture of the foreshore is subjected to the duality of these zones. Time is the contingency which regularly transforms the surrounding site of the architecture and thus regularly transforms its context. This research asks to what extent architecture can expand on the temporal condition of the coastal threshold, and make it spatially appreciable to people? Architecture is a key tool in creating static boundaries, but what if buildings could call attention to blurred boundaries? How might it respond to the dynamics of the foreshore? How might it be blurred by the coast?

This research builds on the work of Jacky Bowring, Nancy Vance and Mick Abbott in ‘Living with the Sea: Knowledge Awareness and Action’ (Brown & Peters, 2018). The authors discuss how coast- situated architecture can challenge the binary oppositions of land and sea, by treating the shared space as a liminal zone. This thesis also draws on the ideas of David Leatherbarrow and Mohsen Mostafavi, whose work discusses how material weathering indicates time and change. To expand upon this theoretical base, an iterative design process of drawing and physical model-making is employed. A sequence of designed experiments are tested to illustrate how architecture may contribute to a greater collective understanding of the temporal coastal space.

This design-led research discusses how key architectural characteristics could modify temporal conditions of the coast, such as rhythm, reflection translucency and weathering. These characteristics are examined as interactive phenomena through three design stages. These stages are iterative, progressively introducing scale and architectural complexity. An installation explores qualities of the coastal threshold through a design test at the scale of the body. A pavilion series highlights the possibilities of mid-scale architecture, while a larger scale building tests ideas through the design of a residence, amphitheatre and jetty. This research begins with a macro-level analysis of the New Zealand coast, then develops a particular focus on the shallow bays of the Waitematā Harbour in Tāmaki Makaurau (Auckland). The design propositions in the second and third stage are sited amid the foreshore of Fitzpatrick Bay in the Waitematā.

This research proposes that architecture can resonate with the temporal phenomena of the coastal zone, which invests it with a contingency of time and a liminal presence. This resonation is distilled as an architecture, with design explorations engaging form, journey, materiality and temporality. Consequently, a dialogue about the architecture, the coast and person’s passage through its temporal and spatial dimensions is communicated.
