Silver film is commonly used to examine the structure and composition of molecules due to its surface-enhanced Raman scattering (SERS) effect. A simple method for preparing SERS silver films is proposed in this paper by electrodeposition in an amide-based liquid mixture (urea-acetamide-LiBr). The electrochemical behavior of silver in urea-acetamide-LiBr mixture was studied by cyclic voltammetry (CV) and chronoamperometry. It was found that the nucleation mechanism of silver shifts to instantaneous nucleation under diffusion control with increasing overpotential and temperature. The energy dispersive spectroscopy (EDS) and X-ray diffraction (XRD) investigations confirmed that the obtained deposits are pure silver. Scanning electron microscopy (SEM) analysis showed that the morphology of the silver deposits depends on the deposition potential and temperature. Rhodamine 6G was used as probe molecules for SERS experiments, showing that these new active substrates have high sensitivity to SERS response with high enhancement factors, of approximately 107, and enable Raman scattering even for diluted solutions. surfaceenhanced surface enhanced (SERS effect amidebased amide based ureaacetamideLiBr. ureaacetamideLiBr urea acetamide LiBr .

ABSTRACT This study focuses on the performance of cows for meat production raised in the wetlands of Paraguay, examining five cattle genotypes: Brahman, Brangus, and Nelore, as well as two local breeds at risk of extinction. The main objective is to identify and rank phenotypic variables, including blood, clinical, hair, and health variables, demonstrating causal linkage with the live weight of the cows analyzed. Initially, high correlations were identified between different variables included in this study; then, using advanced Machine learning (ML) techniques and the application of Shapley additive explanations (SHAP), a deeper understanding was provided of the factors strongly associated with adaptability in these environments, and, therefore, the respective zootechnical performance. The association between cattle genotypic components linked with the season of the year proved to be the most influential factor on cattle live weight. Variables such as hair length, hematocrit, phosphatase, phosphorus, creatine phosphokinase, creatinine, protein, cortisol, calcium, and the presence of endoparasites were highlighted, demonstrating their hierarchical importance for animal selection. ML models are effective tools for establishing hierarchies of relevance in complex phenotypic multivariable, which is crucial in breeding programs for different zootechnical species and in special and specific environments like wetlands. Paraguay genotypes Brahman Brangus Nelore extinction blood clinical analyzed Initially then (ML SHAP, SHAP , (SHAP) therefore length hematocrit phosphatase phosphorus phosphokinase creatinine protein cortisol calcium highlighted selection multivariable (SHAP

Hierdie sewe-jaar longitudinale opvoedingstudie evalueer drie akademiese afleweringsmodusse vir deeltydse MBA-studente in hul Bemarkingsbestuursmodule, naamlik vol kontak (20172019), vol aanlyn tydens COVID-19 se harde inperking (2020-2021 en die daaropvolgende gemengde modus (2022-2023). Die studie het ten doel om te bepaal of die afleweringsmodus studente se akademiese prestasie beduidend beïnvloed. Die eenrigting-variansie-analise (EVA) het beduidende verskille tussen die afleweringsmodusse vir individuele opdragte (normatiewe assessering) en groepgevallestudies (summatiewe assessering) geïdentifiseer. Daar was ook betekenisvolle verskille tussen die akademiese prestasie ten opsigte van die finale saamgestelde portefeulje van kennis (wat as eksamen dien). Hierdie portefeulje bestaan uit 'n prakties-toegepaste bemarkingsplan. Die post-hoc toetse het getoon dat studente aansienlik beter gevaar het tydens die gemengde afleweringsmodus in individuele opdragte, terwyl die volledige aanlyn modus laer punte vir die groepgevallestudies gehad het. Beide die gemengde en volledige kontakmodusse het beduidende opeenvolgende verbetering vir die groepgevallestudies getoon, wat in elke gevallestudie verbetering getoon het namate die semester gevorder het. Dit verskil van volledige aanlyn onderrig. Die gemengde modus het ook aansienlik beter gevaar in die eksamen- en finale modulepunte en het selfs beter gevaar as volkontakklasse.

The COVID-19 pandemic significantly transformed the tertiary education landscape. Traditional contact universities were forced abruptly to adopt a full-distance education mode, a situation neither the students nor lecturers were prepared for. Many lectures and teaching activities were developed on the fly as universities struggled to roll out the needed support in double-time for lecturers and students. This new normal for education required integrating technology, advanced communication software, revised assessment techniques, and recognising the need for flexible and adaptable approaches to teaching and learning. Students also evolved and gained technological proficiency, adaptability, time management, soft skills, social media proficiency, and an awareness of health and well-being. Albeit uncertain in redefining the new normal, universities continue to provide quality education. However, exactly how university education should be delivered to a new breed of students in a new business environment is a challenge. This is even more so in the case of executive MBA students. After the hard lockdown and restrictions were lifted on 21 September 2020, the North-West University Business School started to explore other modes of academic content delivery. Reinstating a full contact delivery mode was not an option because of remaining restrictions. High technological investment, online-educated lecturers and students, and benefits and developments during online learning now form a new normal for the Business School. Which teaching method, or rather, which mode of delivery, is the most relevant and adequate? Should the MBA lectures return to the historic full-contact delivery mode, stick with the newly established full online mode, or attempt to integrate the benefits of both into a hybrid mode of delivering business education to a new breed of technology-savvy students? This study, therefore, examines the academic performance of the different delivery modes by comparing data of Executive MBA Marketing management students at the NWU Business School in South Africa. The study examines the academic performance of these students from 2017 up to 2023. The panel database consists of Executive MBA students'marks for the module in Marketing Management from 2017 up to 2023. The database contains marks for individual assignments, groupwork case studies, final individual- and groupwork marks, exam marks and the final module mark. The final assessment is a portfolio of evidence comprising a detailed marketing plan for a product, service, or organisation of choice. The mode of delivery served as the dependent variable, while the independent variables comprised the marks for each assignment (groupwork, individual and portfolio of evidence). Three delivery modes were compared, namely full-contact (2017-2019), full-online (2020-2021), and the post-pandemic hybrid mode currently in effect (2022-2023). The data comprised 630 cases. However, the analysis of variance (ANOVA) used 532 cases to compare the different groupwork assignments (230 full-contact students, 159 full-online students, and 143 hybrid students). Cronbach's alpha coefficient measured the data's reliability, and one-way ANOVA determined significant differences (p<.05) between the academic performance of the three delivery modes. The analysis confirmed that significant differences exist between the modes of delivery for individual assignments, group case studies and exams (p<.05). The Tukey ab post-hoc tests showed that students performed significantly better during the hybrid delivery mode in individual assignments (69.2%) than full contact (63.8%). Regarding the individual assignment, the full online (63.8%) and full contact (63.7%) delivery modes perform significantly worse than the hybrid (69.2%) delivery mode. Regarding the first group case study (Group Assignment 1), full online performs (67.3%) significantly worse than hybrid (71.1%) and full contact (73.6%) delivery modes. There is no significant difference between the hybrid and full contact delivery modes. In the second, third, and fourth group case studies (Group Assignments 2, 3 & 4), the hybrid delivery mode (82.37%, 75.4%, 82.7%) outperforms the full contact (75.4, 80.1%, 86.6%) and full-online (71.4%, 71.4%, 67.8%) modes. The hybrid delivery mode, therefore, proves to be more conducive towards academic performance in group work. Finally, in considering the final module mark, the hybrid delivery mode (71.0%) is significantly higher than the other two delivery modes. However, there is no significant difference between full online (67.5%) and full-contact (67.2%) delivery modes regarding the final module mark. Nevertheless, it is noteworthy that the better performance in the final module marks is a function of the groupwork where the students analysed case studies together. There are no significant differences in the exam marks between the delivery modes, so better academic performance in the hybrid mode of delivery where groupwork is concerned culminates in the better module mark. Based on the findings, it is evident that the hybrid mode of delivery results in the best academic performance. This observation is based on three reasons, namely 1) students performed better in both the normative and summative assessments during hybrid tuition; 2) there is continuous progressive learning throughout the semester regarding the group case studies (summative assessment). They learn to improve and hone their skills to analyse better and apply business solutions to real-life problems experienced by organisations. This is based on students' improving marks in the group case studies as they become more proficient in analysing and answering the applied case studies because they learn from each case study; and 3) the students perform better academically in their normative assessments and earn higher final module marks (partially due to reason 2). It is concluded that the hybrid delivery mode facilitates the academic performance of post-pandemic executive MBA Marketing management students. JEL KODES: I23, I21, M30

The South African food system is facing severe challenges as increasing hunger, rising food costs, lack of dietary diversity, child stunting, foodborne illnesses, food waste and an obesity epidemic coupled with malnutrition are observed. In this study, we aimed to establish the application of science and technology advances in the food and beverage industry in South Africa in response to food consumption pattern changes since 1994 and how they could be used to address food security challenges. We found that food consumption shifts have been towards sugar-sweetened beverages, processed and packaged food, animal-source foods and added caloric sweeteners, and away from vegetables. These dietary shifts are concerning as they relate to public health. Most commitments to improve the nutritional status of South Africans have been limited to corporate social investment strategies and should be extended into core business strategies. Furthermore, although the South African food and beverage industry has kept pace with developments in food manufacturing practices, there has been little experimentation with non-commercial novel technologies. The expert survey revealed that indigenous African crops and food waste recovery are the two most promising emerging food sources that could be available to South Africans in the shortest time frame. South Africa has many enabling drivers to become a global leader in food technology advances. However, many barriers need to be overcome for industry, academia and government to collaborate to advance novel food science and technologies to reach commercialisation. SIGNIFICANCE: • Drivers and consequences of food consumption changes in South Africa were modelled and broad food consumption trends between 1994 and 2009/2012 were identified. • For the first time, the Access to Nutrition Index methodology was applied to South African owned food companies to identify strategies to enhance nutrition practices. Companies need to do more to deliver affordable and accessible products. • Drivers and barriers in adopting advanced food science and technology were modelled. A collective ecosystem approach with industry, academia and government mobilisation around critical areas like hunger, malnutrition and poverty could be a way to tackle the failing food system.

Resumen El cáncer gástrico es un proceso fatal cuyos factores de riesgo incluyen la infección por Helicobacter pylori, la anemia perniciosa, la ingesta de compuestos nitrosos, el abuso de alcohol, el tabaquismo y el sexo masculino. El seguimiento endoscópico ha definido la progresión histológica de lesiones premalignas a lesiones malignas. Sin embargo, los tumores gástricos exhiben diferentes y muy variadas variaciones histológicas, comportamientos clínicos y respuestas a tratamiento. Esta gran heterogeneidad intrapaciente e interpaciente ha obligado a la búsqueda de principios reguladores que gobiernen la evolución del cáncer gástrico. Los programas avanzados de bioinformática, la tecnología de microarreglos de ADN y la genómica funcional han ayudado a integrar la estructura, función y dinámica de moléculas biológicas expresadas o secretadas por las células epiteliales cancerosas que han modificado la clasificación del cáncer gástrico.

Abstract Gastric cancer is a fatal process whose risk factors include infection by Helicobacter pylori, pernicious anemia, nitroso compounds, alcohol abuse, cigarette smoking, and male gender. Endoscopic surveillance has defined the histological progression of premalignant to malignant lesions. Nevertheless, gastric tumors exhibit distinct histologic variations, clinical behaviors, and treatment responses. This “intra and interpatient heterogeneity” has obliged us to search for key principles governing gastric cancer evolution. Advanced bioinformatics programs, DNA microarray technology, and functional genomics have helped to integrate the structure, function, and dynamics of biological molecules expressed or secreted by cancer epithelial cells that have modified the classification of gastric cancer.

Abstract Information and Communications Technologies (ICT) have followed a trajectory of systematic and accelerated development, marking transformations in various sectors of society. In this dynamic context, higher education institutions face the imperative to adapt and evolve in a coherent and strategic manner in response to technological, scientific-technical and methodological progress. Recognition of levels of integration in postgraduate training processes and these technologies is required. From this perspective, the general objective was proposed to describe advanced experiences based on pedagogical experiences in Graduate Education at the Graduate Faculty of the Technical University of Manabí (UTM). A descriptive, transversal methodology with a non-experimental design was used, with various scientific methods, such as documentary, analytical-synthetic, systematization, unstructured interviews and case studies. The reality of the postgraduate programs in the Graduate Faculty of the UTM was analyzed, with the use of ICT, and in correspondence the emergence of strategies aimed at updating teachers was expressed. Various authors were consulted with studies related to the use of virtual environments and the online modality in the 4th level, and it was possible to see that the trend is to increase this modality in the programs and thus makes them more competitive and with greater demand.

In this study, the typical azo dye methyl orange (MO) was degraded by pyrite (FeS2) activated by hydrogen peroxide (H2O2). When [MO] = 0.1 mM, [FeSJ = 2.0 g/L and [H2O2] = 22 mM, 96.4% MO was removed in 120 min and the TOC removal rate was higher than 50%. HO* was the primary radical responsible for MO degradation, in addition, the acid condition promoted the degradation of MO in the FeS2/H2O2 system. MO in tap water and river water was not effectively degraded, whereas acidification could weaken the inhibitory effect on the FeS2/ H2O2 system to enable the degradation of MO in tap and river water. The OD600 indicated that the solution was environmentally friendly after the reaction, and three degradation pathways of MO were discussed. In summary, Fe(ll) could be dissolved from FeS2, which activated H2O2 to generate Fe(lll) and HO*. FeS2 could reduce Fe(lll) into Fe(ll), thus realizing the Fe(lll)/(ll) cycle and efficiently activating H2O2 to degrade MO.

The mining industry has yet to fully accept and embrace the strategic role of technology and innovation in successful business planning and execution. In this study, we empirically determine the factors that influence acceptance of technology solutions in the mining industry in South Africa, assess critical success factors influencing adoption of advanced technology in the South African mining industry, and explore challenges faced by the mining industry in South Africa in adopting advanced technology in its operations. Thematic content analysis is employed in the data analysis. Results show that critical success factors to the adoption of mining technology include learning culture, knowledge sharing, high labour costs, and behaviour of other firms in the industry; commonly identified challenges include inadequate engagement with external stakeholders, uncertainties, the cyclical nature of the sector, and high risk related to the adoption of unproven technology and performance systems focused on volumetric production. The study encourages mining companies to implement usage of technology. This can be properly done through regular engagement with the Minerals Council South Africa.

Reliable cable systems are of utmost importance for electricity distribution- and grid networks. Cable terminations are key components of cable systems but also contribute significantly towards unwanted cable failures and power outages. Although well-developed standards exist in the electricity industry, it is not always possible to execute the most effective tests at power frequency due to financial or logistical reasons. Hence, withstand voltage- and Partial Discharge tests at power frequency are only conducted at a low percentage of electricity utilities. This paper presents the evaluation of unconventional partial discharge fault detection techniques and Very Low Frequency Tan Delta measurements on different cable termination defects. Five artificial cable termination defects were created on single core 6.35/11kV cross linked polyethylene cables, with one "defect-free" termination and five defective ones. Power frequency voltage was applied at increased voltage steps to initiate aging acceleration due to partial discharge. This resulted in insulation deterioration and eventual termination failure. Different data sets were obtained from the Very Low Frequency Tan Delta measurements as well as for the unconventional Partial Discharge measurements. The sequence of failures is compared between the two data sets and evaluated against the root cause failures of the terminations as evaluated by an industry expert. High Frequency Current Transformer and capacitive coupling sensors were used together with an advanced partial discharge data acquisition system. Partial discharge analysis was done to relate the specific on-line trending data with termination failure. Good correlation was found between the two data sets which supports the utilization of unconventional partial discharge measurement for cable acceptance testing. It would be beneficial for the electricity industry to consider unconventional Partial Discharge technology as a suitable alternative for on-site acceptance tests for cable terminations.
