Authors: Deebani Wejdan , Rooman Muhammad , Vrinceanu Narcisa , Shah Zahir , Shutaywi Meshal , Jeli Roqia Abdullah A.
Published: July 2023

Homogeneous and heterogeneous reactions play a decisive role in biological procedures such as burning, polymer creation, ceramic construction, distillation, and catalysis. The magnetic properties of hemoglobin molecules are organic. Magnetic resonance imaging (MRI) and electronic components with an electromagnetic field are now readily available, allowing for the explanation of fundamental biological processes. These ideas form the foundation of an ongoing study that attempts to look into the impact of both homogeneous and heterogeneous reactivity on the peristaltic transport of magnetohydrodynamics Oldroyd-B fluid. When convective and partial sliding conditions are present, the configuration changes to a non-uniform vertical channel. The fundamental partial differential equations are resolved utilizing the Homotopy Analysis Method. Entropy optimization has been carried out. The primary limits entering the problem are investigated, and then a graph is used to show the influences of temperature, velocity, skin fraction, Nusselt number, and pressure increase against mean circulation, trapping phenomena, homogeneous reactions, and heterogeneous way to respond. When magnetic parameter rises, the velocity of Oldroyd-B fluid and Bejan number decrease, while temperature, entropy generation, and pressure gradient increase. The tables show that the skin friction coefficient rises for accumulative values of the Grashof number and magnetic parameter, while the skin friction coefficient drops for rising values of the velocity slip parameter and Reynolds number. The Nusselt number increases for large values of Eckert, Grashof numbers, and magnetic parameters.
Rola kobiet we wczesnonowożytnej wojskowości: próba spojrzenia na przykładzie siedemnastowiecznej armii hiszpańskiej
Authors:   Uniwersytet w Białymstoku, Szadkowski Paweł
Published: July 2023

This article is devoted to the different roles played by women in the seventeenth-century Spanish army. As the issue of the presence of women in pre-industrial armies has not received much attention among researchers, the problem is still presented according to stereotypes shaped by nineteenth-century historiography and the early works of military historians. In their light, women in the armies of the early modern era assumed at best the role of servants, laundresses, cooks or offered sexual services. More recent works by historians of social military history, however, shed a completely different light on the issue, showing them not only as actively participating in army life, but also as taking up arms or seeking help for themselves and their soldiers’ orphans after the war. In this article, I will present the three roles of women that emerge from the sources – woman in armed combat, widow and mother – for the seventeenth-century Spanish army.
Julki, alternatywki, zodiakary. Stereotypy kobiet w młodomowie
Authors:   Uniwersytet Jana Kochanowskiego w Kielcach, Wileczek Anna
Published: July 2023

The article analyzes contemporary examples of stereotyping of (young) women with the help of label nominations. The indicated neologisms, labeling particular groups of people, duplicate and consolidate in the social opinion negative and – usually – deprecating judgments, contributing to the formation of stereotypes. The new labels (such as bedoesiara, julka, karyna, konserwatywka, and madka) result from expressive and valorizing cognitive simplifications. An emotional and humorous element dominate them because they are based on specific, emotional reactions to contact with the so-called typical units (cf. typical julka, typical rzepiara, typical madka). These neologisms, by labelling given groups of people, reproduce and reinforce in social opinion negative and, usually, biased judgments, which results in new stereotypes.
Cellulosic ethanol production from sugarcane bagasse without enzymatic saccharification
Authors: Dawson Letha , Boopathy Raj
Published: July 2023

Sugarcane processing generates a large volume of bagasse. Disposal of bagasse is critical for both agricultural profitability and environmental protection. Sugarcane bagasse is a renewable resource that can be used to produce ethanol and many other value-added products. In this study, we demonstrate that cane processed bagasse could be used to produce fuel grade ethanol without saccharification. A chemical pre-treatment process using alkaline peroxide and acid hydrolysis was applied to remove lignin, which acts as physical barrier to cellulolytic enzymes. Yeast Saccharomyces cerevisiae ATCC, strain 765, was used in the experiment. The pre-treatment process effectively removed lignin. Ethanol production in the culture sample was monitored using high performance liquid chromatography. The results indicate that ethanol can be made from the sugarcane bagasse.

Published: July 2023

Pulping of bagasse by one-stage and three-stage peroxyacetic acid was carried out. Characterization of the precipitated lignin from the waste liquor of the pulping process was studied using infrared spec-troscopy. Comparison between the molecular structure of peroxyacid lignin and kraft lignin was investigated. Different lignins were applied to phosphorylation reaction. The sodium binding capacity and metal ions absorption by these lignins were taken into consideration. Infrared spectroscopy of the produced phosphorylated lignin was investigated. The peroxyacid lignin was found to have lower OH, higher COOH, a higher level of phosphate groups, and a higher binding capacity for sodium compared to kraft lignin.

Published: July 2023

El artículo condensa el periodo en el cual Ana María Rico Galán tomó decisiones claves en su vida personal al involucrarse en el Movimiento Revolucionario del Pueblo (MRP, 1964-1966), cuyo propósito fue la toma del poder mediante las armas. No se conoce su praxis política ni sus ideas revolucionarias. Mi acercamiento a sus contornos biográficos, en el periodo de su mayor actividad política en la configuración del MRP, lo realizo mediante el acopio de instrumental teórico metodológico desde la historia política de la izquierda y la historia de las mujeres y de las relaciones de género. Mi intención es que, al darle visibilidad en el concierto de los estudios del movimiento armado socialista en México, se concrete como un aporte con enfoque de género en el examen de mujeres transgresoras que perseguían el paradigma de la revolución.
Management Public Accounting: An Analysis of Cost Information in the Light of Public Managers’ Perception
Authors: Cardoso Giuliano Passos , Rodrigues Evaldo César Cavalcante
Published: July 2023

This article aims to investigate the usefulness of cost information in the Brazilian federal government, through observation and empirical analysis of the perception of public managers, who are the main users of this information. The data collected from managers of different government entities were treated using the Multicriteria Decision Aid (MCDA) methodology, in order to highlight the interviewees’ perception of the purposes, conditions, and mechanisms of access to information. The results showed broad recognition by managers about the usefulness of information, triggering a discussion that puts forward that the vast standardization, the search for improvements in accounting standards, and technological advances are not enough for innovative cost management practices to be successful in public organizations. These reflections indicate the need for alignment between information generated by the cost system and its users, that is, between cost accountants and cost managers, so that the institutionalization of the system does not become a mere formalism of the public sector bureaucracy.

O artigo tem como objetivo investigar a utilidade da informação de custos no governo federal brasileiro, mediante observação e análise empírica da percepção dos gestores públicos, principais usuários da informação. Os dados coletados junto a gestores de distintas entidades do Governo Federal foram tratados mediante metodologia Multicriteria Decision Aid (MCDA), a fim de evidenciar a percepção dos entrevistados sobre propósitos, condições e mecanismos de acesso da informação. Os resultados demonstraram amplo reconhecimento dos gestores sobre a utilidade da informação, desencadeando a discussão de que a vasta normatização, a busca por melhorias nos padrões contábeis e os avanços tecnológicos não são suficientes para que práticas inovadoras de gestão de custos sejam bem-sucedidas nas organizações públicas. As reflexões indicam a necessidade de alinhamento entre informações geradas pelo sistema de custos e seus usuários, ou seja, entre contadores de custos e gestores de custos, para que a institucionalização do sistema não se traduza em mero formalismo da burocracia do setor público.

Published: July 2023

In neurobehavioral research, animal model has played a crucial role in yielding experimental data as well as, in the development of new insights. Researchers are always trying to develop novel animal models to understand fundamental features of physiological, behavioral and psychological disorders. Zebra fish (Danio rerio) is now considered globally as a new and useful model in biomedical research. The objective of the present study was to assess behavioral changes in adult zebra fish after acute exposure to different pharmacological and herbal compound. Adult zebra fish of 4-5-months-old were exposed to different concentrations of unknown test drug with the standard for 5 min. The test was conducted separately for each drug concentration as well as control. Behavioral activity parameters viz. novel tank test and light and dark transition test were recorded for each animal during the exposure period. Results: Zebra fish exposed to Test drug (Calycophyllum Spruceanum) showed change in behavioral activity with significant to the standard drug caffeine. In view of the above findings, these results suggested that exposure of adult zebra fish with drug produce the expected changes in the behavior like stress and anxiety; therefore, adult zebra fish can be used an alternative approach for the assessment of new chemical entities for their effect on behavioral activity.

Published: July 2023

The consumption of legume seeds has benefits for human nutrition and health. Seeds of Leucaena leucocephala and Leucaena esculenta are fast-growing legumes that are used for a variety of purposes. In general, they are used to preserve/restore the soil; the foliage can be used as fodder for livestock and the seeds for human consumption in rural populations. Leucaena seeds are a source of nutrition, since they contain proteins, carbohydrates and lipids (including omega 3, 6 and 9 unsaturated acids). The protein fraction has shown pharmaceutical effects of interest (analgesic, lipolytic, emollient, anticancer, anti-inflammatory, anti-coagulant and anti-diabetic) and some techno-functional properties for the food industry. However, the main limitation to the human consumption of leucaena seeds is the presence of mimosine, an antinutrient that produces side effects such as alopecia, growth retardation, cataracts and infertility in animals. In this sense, some technological processes that could contribute to its decrease. This work was carried out at the Nutraceuticals Department of the Interdisciplinary Research Center for Integral Regional Development, Oaxaca Unit, Mexico. A comprehensive and integrative review of research work carried out in different parts of the world was conducted. The bibliographic search was carried out from January 2020 to January 2022. Several databases such as Scopus, Latindex, Dialnet, Redalyc.org, FAO and Academic Google were explored. A total of 81 documents were used to prepare this review document. This review integrates aspects related to the potential use of leucaena seeds in human nutrition: nutritional composition, pharmacological, techno-functional properties, the processes to improve digestibility and reduce toxicity.

Climate Extremes and Protests in India, Pakistan and Bangladesh, 1995-2013
Authors: Werum Regina Elisabeth , Schaefer Daniel , Zhang Beichen
Published: July 2023

Scientists have shown a relationship between climate conditions and social unrest, specifically related to temperature and precipitation trends. Though deviations from historically normative patterns are becoming more pronounced, it remains unclear to what extent they affect protests, linearly and otherwise. Similarly, we know little about the extent to which climate anomalies create contemporaneous versus lagged effects on protests. To address these questions, we examine determinants of protest levels between 1995 and 2013 in India, Pakistan, and Bangladesh.
Our innovative methodology involves modeling geocoded, media-reported protests (derived from the Integrated Crisis Early Warning System) at 0.5x0.5 degree geospatial resolution, using unobtrusive, satellite-derived data on temperature and precipitation patterns and historical deviations. We also integrate comparable satellite data on nightlight pollution. Properties of our outcome variable require negative binomial regression analysis.
We find that, net of controls gauging local demographic and country-level dynamics, temperatures and precipitation directly impact protests in unexpected ways: In any given year and location, protests are strongly, positively associated with heavy precipitation and with higher temperature levels. Protests are also strongly, positively associated with historical deviations in precipitation patterns. This applies to anomalies related to both wetness and dryness. Finally, historically aberrant precipitation has pronounced curvilinear, lagged effectson protest levels. We situate these complex findings in light of classic, structurally based arguments grounded in social science theory.

Published: July 2023

This paper presents the dynamic characteristics of the glued-laminated-timber (glulam) floor in China's tallest wooden office building and establishes a Finite Element (FE) model. The FE model's applicability is verified through experiments. The study investigates the effect of Reinforced Ribbed Wood Beams (RRTB) on floor vibration characteristics and evaluates the comfort index. Ambient Vibration Test (AVT) and human walking tests was carried out on the specific floor. The results show that the RRTB significantly increase the overall stiffness of the floor, and change the natural frequency and modal vibration shape of the floor. The thickness of the RRTB has a more significant effect on the dynamic characteristics of the floor compared to its width. The static deflection of the floor is the most sensitive to the size change of the reinforced ribs, compared to the fundamental frequency and maximum displacement. For high-rise glulam building floors, AVT can be effectively applied to fundamental frequency testing; Even if the fundamental frequency of the floor meets the comfort index, acceleration and velocity amplitude tests are still necessary.
A blind area information perception and AR assembly guidance method based on RGBD data for dynamic environments and user study
Authors: Hou Zhenghang , Zhang Qiang , Wang Shuxia , He Weiping , Zhang Shaohua
Published: July 2023

In this research, a blind area information perception and guidance approach for dynamic context is proposed as a solution to the issue of difficult and time-consuming assembly in blind areas. The proposed approach involves the utilization of real-time RGBD data to perceive both blind area context and operator hand information. The resulting data is then used to visualize the blind area scene and provide assembly guidance through the application of augmented reality technology. Unlike conventional methods, the proposed solutions are based on dynamic RGBD data rather than static predefined CAD models, making it simpler to configure and adapt to more scenarios. A user study was designed and conducted to confirm the feasibility of the suggested approach. The results indicate that the suggested approach can decrease assembly time by 49.5%, greatly lower the percentage of assembly errors, reduce the mental load on the workers, and significantly enhance their operational experience.

RAC1 P29S is the third most prevalent hotspot mutation in sun-exposed melanoma. RAC1 alterations in cancer are correlated with poor prognosis, resistance to standard chemotherapy, and insensitivity to targeted inhibitors. Although RAC1P29S mutations in melanoma and RAC1 alterations in several other cancers are increasingly evident, the RAC1-driven biological mechanisms contributing to tumorigenesis remain unclear. Lack of rigorous signaling analysis has prevented identification of alternative therapeutic targets for RAC1P29S-harboring melanomas. To investigate the RAC1P29S-driven effect on downstream molecular signaling pathways, we generated an inducible RAC1P29S expression melanocytic cell line and performed RNA-sequencing (RNA-seq) coupled with multiplexed kinase inhibitor beads and mass spectrometry (MIBs/MS) to establish enriched pathways from the genomic to proteomic level. Our proteogenomic analysis identified CDK9 as a potential new and specific target in RAC1P29S-mutant melanoma cells. In vitro, CDK9 inhibition impeded the proliferation of in RAC1P29S-mutant melanoma cells and increased surface expression of PD-L1 and MHC Class I proteins. In vivo, combining CDK9 inhibition with anti-PD-1 immune checkpoint blockade significantly inhibited tumor growth only in melanomas that expressed the RAC1P29S mutation. Collectively, these results establish CDK9 as a novel target in RAC1-driven melanoma that can further sensitize the tumor to anti-PD-1 immunotherapy.
Numerical Investigation of the Effect of Swab and Surge Pressure on the Time-Dependent Wellbore’s Development of Natural Fractures

Published: July 2023

During drilling operations, the wellbore pressure is subjected to fluctuations caused by some factors such as swab and surge pressure which can result in wellbore instability. In this research, a numerical model is built using the ABAQUS software to demonstrate the effect of swab and surge pressure on the wellbore’s growth of natural fracture and the time dependent pore pressure. A MATLAB program is then developed to determine the safe mud window by computation of the time dependent wellbore collapse pressure and fracture pressure. The results demonstrated that the fracture width as a function of time profiles increased with the swab and surge pressure. The biggest percentage increase of the fracture width after incorporation of swab and surge pressure was 70%. Interestingly, an increase of 69% of the fracture width was observed in the near wellbore region after application of swab and surge pressure. However, the fracture length, the loss circulation rate and the pore fluid pressure remained relatively unchanged after integration of swab and surge. The analysis of the time-dependent wellbore stability revealed that the mud window, which was initially constant, narrowed with the time after integration of swab and surge pressure. The collapse pressure without swab and surge pressure increased by 14% while the fracture pressure decreased by 14%. The numerical model was verified by evaluating the gap between ABAQUS numerical results and analytical solutions and good consensus was observed after comparisons. The model developed in this research can be useful for wellbore strengthening studies to determine the optimal Particle Size Dimension necessary to plug the natural fractures and mitigate the lost circulation.
Fake Detection in Imbalance Dataset by Semi-Supervised Learning with GAN
Authors: Bordbar Jinus , Ardalan Saman , Mohammadrezaei Mohammadreza , Shiri Mohammad Ebrahim
Published: July 2023

As social media grows faster, harassment becomes more prevalent, which leads to the consideration of fake detection as a fascinating field among researchers. The graph nature of data, with a large number of nodes, causes different obstacles, including a considerable amount of unrelated features in matrices, as well as high dispersion and imbalanced classes in the dataset. To address these issues, Auto-encoders and a combination of semi-supervised learning and the GAN algorithm, called SGAN, were used. This paper deploys a smaller number of labels and applies SGAN as a classifier. The results of this test showed that the accuracy reached 81% in detecting fake accounts using only 100 labeled samples.
In vitro callus and shoot initiation of Black cohosh (Actaea racemosa. L) pre-incubated in darkness treatments
Authors: Robinson Julia , Yang Guochen , Lu Zhongge (Cindy)
Published: July 2023

A medicinal plant that is commonly overharvested in its native habitat, Black cohosh (Actaea racemosa L.) rhizomes are used to mitigate symptoms of menopause and are a common alternative to hormone replacement therapy. Developing an accurate protocol for initiation of Black cohosh in tissue culture is becoming a necessity. Wild harvesting practices are the main source of Black cohosh rhizomes processed by pharmaceutical companies and are causing a significant decrease of these wild plants, leading to an At-Risk status. Growing these plants in a plant tissue culture laboratory is more sustainable than current practices, and having an accurate protocol for initiation of these plants is crucial to this. Our lab has previously developed a protocol for initiation of Black cohosh and this research was meant to optimize this protocol. Leaf explants of Black cohosh were cultured in vitro to determine the optimal duration of time for initiation of callus and/or shoot under darkness, and appropriate plant growth regulators (PGR) for shoot growth. Leaf explants incubated under darkness for increasing amount of time (0 to 6 weeks of darkness) were analyzed at two stages of tissue development. Stage 1 involved initiation of leaf explant material under darkness (treatment) and measured the callus development in leaf explants; Stage 2 was induction of adventitious shoot growth and cell division and compared the effect of two PGRs, KT and BA, on shoot growth for each darkness treatment. Leaf explants were given a score using a culture chart that assigns a numerical score to leaf explants based on their physiological characteristics. These numerical scores took into account color of leaf explant, callus development, shoot growth, and presence of dead leaf tissue. Stage 2 measured the number of shoots produced per explant within culture containers between PGRs and the number of weeks in darkness. Overall trends indicated that mortality of leaf explants decreased as the duration of incubation under darkness increased with mortality of explants decreasing from 63.9% (T0 darkness treatment) to 2.8% (T6 darkness treatment). Culture scores of explants (including dead explants) was highest for T6 weeks of darkness (culture score 2.96 on average), and for culture scores without dead explants (culture score of 3.05). During the adventitious shoot growth stage, however, T5 weeks of darkness performed significantly higher (KT: 28 shoots/ BA: 17.3 shoots) than T6 weeks of darkness (KT: 12.9 shoots/ BA: 9.4) in Replication 2 for both plant growth regulators KT PGR performed better, on average, than BA PGR

Objective. The objective of this study is to evaluate the impact of psychosocial risks based on the demographic variables of sex, age, and seniority, on the perception of workplace violence in a group of workers from Spanish companies. Methods. a total of 22 Spanish companies were analysed between 2016 and 2018 with a total sample of 26741 people using the FPSICO 3.1 psychosocial assessment method and divided into demographic groups of sex, age, and seniority for subsequent comparison of means and regression analysis. Results. The results confirm the relationship between psychosocial risks and the perception of workplace violence. The analysesby demographic variables position the group of men as the group with the highest perception of workplace violence, except for discrimination, where it was higher in the group of women. The results confirm that the perception of workplace violence increases significantly with age and seniority in the company. Conclusions. workplace violence is one of the most worrying risk factors today and it is necessary to better understand what risk factors can favour its appearance or its differentiated behaviour according to sex, age, or seniority. This can allow us to develop planned strategies to control this risk and focus on specific demographic groups.

Although microbiology and neurology are separate disciplines, they are linked to some
infectious and neurological diseases. Today, microbiome is considered as one of the biomarkers of
health by many researchers. This has led to the association of microbiome changes with many
neurological diseases. The natural microbiota has many beneficial properties. If disrupted and altered,
it can lead to irreversible complications and many neurological diseases. Therefore, according to
previous studies, some preventive and therapeutic complementary therapies can prevent or restore
microbiome dysbiosis and inflammation in the nervous system. With our current perception of the
microbiological basis for different neurological disorders, both aspects of drug treatment and control of
perturbations of the microbiome should be considered, and targeting them simultaneously will likely
help to attain favorable results.

Published: July 2023

Introduction:

The paper presents the results of experiments on the purification of air con-taminated with S. aureus, as well as the destruction of yeast under the action of cold nonequilibrium plasma of a nanosecond streamer corona discharge.

Methods:

It is shown that plasma is an effective means for destroying both bacteria in the air and biological objects on the surface. The main parameters of the nanosecond streamer corona discharge and their relationship with the operating time of the active plasma components were determined. It was experimentally established that the inactivation time of 80% of S. aureus bacteria with a con-centration of 2.1∙104 KOE m-3 was 0.4 s with a specific energy of 28 J∙l-1.

Results:

The results of measurements of the dependence of the yeast destruction degree on the yeast size, the time of direct exposure to the nanosecond streamer corona discharge, active elements of cold nonequilibrium plasma, and third-party ultraviolet radiation are presented.

Conclusion:

A comparison of the results of air disinfection experiments with data on yeast destruc-tion shows that the latter can be used for rapid analysis of the effects of low-temperature plasma on other biological objects.

Published: July 2023

Aim: Many antioxidant compounds have been tried to prevent traumatic brain injury (TBI). In this study, we aimed to demonstrate the therapeutic effect of Resveratrol in the hippocampus in TBI by histopathologic and immunologic evaluation.

Study Design: Twenty-four male Sprague-Dawley rats were divided into Control, TBI, TBI+Resveratrol (20 mg/kg/day, oral) groups. Rats were subjected to traumatic brain injury by dropping the weight from a height with a 50 g/1m weight-height impact device. All rats were decapitated 14 days after trauma induction and the protective effects of Resveratrol were evaluated by histopathological and immunohistochemical analyses.

Result: In the TBI group, degeneration of cells, dilatation of vessels and apoptosis due to traumatic inflammation were observed in the alveus and pyramidal layer. In the plexiform layer, synaptic degeneration was present in nerve extensions. In TBI+Resveratrol group, vascular dilatation was decreased and axonal extensions were normal, hyperplasia was observed in pyramidal neurons. S100 expression was positive in pyramidal neurons, glial cells and vascular endothelium. In the Resveratrol treated group, negative expression was observed in membranes, pyramidal neurons and positive s100 expression was observed in plexiform layer and axons.

Conclusion: We suggest that after TBI, Resveratrol treatment alleviates cerebral tissue pathology and can be demonstrated by s100 expression in neuronal regeneration.

Keywords: Traumatic brain injury, hippocampus, s100, Resveratrol, immunohistochemistry

In recent years, Ukraine has allocated considerable financial resources for agricultural support according to their demands on the budget. However, the increase of domestic support has not substantially influenced the effectiveness indices of agricultural yields. This demonstrates the imperfect nature of the internal support mechanisms for Ukrainian agriculture. As a result, domestic support has not become an effective stimulus for increases in production quality or stock/breeding production. In 2013, Ukraine gathered its biggest grain harvest. This increase in production did not, however, improve the financial results for agriculture and did not produce stable and dynamic branch development due to the negative influence of the global financial crisis. An unbalanced supply and demand of agricultural production, low buying ability of inhabitants, and the lack of an effective mechanism of domestic support caused several problems with price in the domestic food market.

This chapter is a systematic review of research on sustainable development in Norwegian education. The review demonstrates that most of the empirical research is conducted in the natural and social sciences, yet with a growing attention to subjects like Norwegian language and arts and craft. To investigate the totality of the perspectives in the reviewed literature we make use of Hopwood et al.’s model. We place each text according to its emphasis on socioeconomic and ecological considerations, and according to an interpretation of it representing a status quo, reform or transformation perspectives. Our findings are that the majority of the literature orients towards ecological considerations, often implicitly articulated, pointing to a neglect of socioeconomic considerations and a narrow understanding of sustainable development. Regarding status quo, reform and transformation, the literature covers all three, with an emphasis towards status quo. We would encourage more research addressing socioeconomic issues and critically exploring avenues that can take us towards transformation.

Published: July 2023

Higher vocational colleges and universities have recently been booming from number to scale. While the increase in enrollment scale and equipment value has brought great benefits to schools and greatly improved their teaching capacity, it has also brought problems to equipment management. In traditional practical training room management, problems such as low equipment utilization, work efficiency, and teaching efficiency are encountered. Along with the development of Internet technology, real-time monitoring and intelligent management of practical training rooms are possible. This paper firstly thus proposes the logical level, management dimensions, and information interaction contents of the intelligent, practical training management system to establish the architecture of the intelligent, practical training management system, and thus leads to the key technologies and methods for the design and establishment of the intelligent, practical training management system. Secondly, starting from the analysis of the training process, the bottom physical environment is sorted out in detail. The four dimensions of equipment status, consumables status, energy consumption status and teaching status of the smart training management system are collected in the information. The smart training management system model is established to analyze the data in a single dimension and derive effective information to help managers manage collaboratively. Finally, the model’s effectiveness is verified by applying the smart training room management system in Z higher education institutions in Xiamen. The study of Xiamen Z higher vocational institution in this paper shows that the use of an intelligent teaching management system effectively improves performance by 34.12%, the affiliation and utility rate of an Bar and coffee training room is better than the traditional training platform, and the influence parameter on the learning process of Xiamen Z higher vocational institution is found to be 79.62 through classification, which provides effective decision for teachers to implement differentiated teaching. The intelligent teaching management system proposed in this paper realizes data visualization of the training room equipment, provides data support for teachers to set differentiated teaching programs, improves teaching efficiency, improves students’ practical training skills through data-based analysis of problems in students’ practical training, and provides motivation for talent training in universities.

Digital transformation and the Fourth Industrial Revolution (4IR) present opportunities for businesses, but also generate disruptive challenges for organizational performance and the labor market, requiring new skills and competencies. Upskilling and reskilling are crucial in a volatile environment that demands a digital mindset. The paper aims to delineate the key challenges and opportunities presented by emerging and disruptive technologies (EDT) concerning the labor market and to identify the top skills required for thriving in the 4IR business environment. Some guidelines are also offered for organizations and managers regarding the necessity to embrace a holistic approach and promote digital IQ, digital dexterity, and employee career development. To prevent a digital divide in a disruptive technological landscape, a comprehensive and responsible skilling strategy is required. Attainment of high-performance levels and competitive advantage through digital transformation mandates leadership competencies in addition to digital capabilities. Furthermore, success in this regard requires cooperation between businesses, industry, educational institutions, and governments, to promote investment in infrastructure and lifelong learning. In order to effectively leverage the potential of EDTs and alleviate the skills mismatch within the context of the 4IR, the education system must undergo a transformation that fosters agility, resilience, and proactive responsiveness to these trends.

Metal-Organic Frameworks (MOFs) have settled in the scientific community over the last decades as versatile materials with several applications. Among those, Zeolitic Imidazolate Framework 8 (ZIF-8) is a well-known MOF that has been applied in various and diverse fields, from drug-delivery platforms to microelectronics. However, the complex role played by the reaction parameters in controlling the size and morphology of ZIF-8 particles is still not fully understood. Even further, many individual reports propose different nucleation and growth mechanisms for ZIF-8, thus creating a fragmented view of the system's behavior. To provide a unified view, we have generated a comprehensive dataset of synthetic conditions and their final outputs and applied Machine Learning techniques to analyze the data. Our approach has enabled us to identify the nucleation and growth mechanisms operating for ZIF-8 in a given portion of the chemical space and to reveal the underlying impact of synthetic variables on the final particle size and morphology. By doing so, we draw connections between the role of each synthetic variable over ZIF-8 synthesis and provided with a rule of thumb to control the final particle size. Our results provide a unified roadmap for the nucleation and growth mechanisms of ZIF-8 in agreement with mainstream trends, which can guide the rational design of ZIF-8 particles with specific sizes and morphology, determining their suitability for any targeted application. Altogether, our work represents a step forward in seeking control of the properties of MOFs through a deeper understanding of the rationale behind synthesis procedures employed for their synthesis.
