The study was conducted on Pompano (Trachinotus sp.) cultured in the circulation water pond from June 2022 to September 2023. The results show that Pompano were negative for the viral pathogens (VNN and Iridovirus). Fish were infected with Vibrio alginolyticus bacteria in both farming crops. The infection rate is 20% and does not cause fish deaths in the June 2022 and April 2023 sampling periods. Meanwhile, in the July 2022 sample collection, the 60% infection rate caused the death of 4.2% of farmed fish. Doxycycline antibiotic used by mixing with food at a dose of 100 mg/kg of fish, feeding fish 1 meal/day for 5 consecutive days was effective in treatment, no fish died after the 6th day; Farmed fish weighing 30-55 g/fish are infected with the parasite Amyloodinium sp. at high infection intensity (100-190 parasites/market) caused 29.1% mortality; These fish were bathed with formol at a dose of 50 ppm. After 3 consecutive baths, 1 day apart each time, the fish stopped dying for 10 days. Parasites Trichodina sp. appear on Pompano with a weight of 80-120 g/fish, infection intensity is 0-5 infections per field (in gills) and 0-15 infections per field (in skin) but does not cause fish death. In larger fish, high intensity Trichodina sp. parasite infection has caused mortality. Specifically: Fish weighing 90-120 g/fish have an infection intensity of 100-250 infections per field, with an infection rate of 100%, causing 12.7% mortality; Fish with weight of 260-320 g/fish, intensity of 10-50 infections per field, infection rate 100%, causing 2.7% mortality. Using copper sulfate at a dose of 5 ppm completely eliminated Trichodina sp. after 3 consecutive baths, 1 day apart.

Published: March 2024

Recently, the problem of community detection has attracted the attention of many scientists. Most types of networks such as computer networks, biological networks and social networks, have a community structure. Community detection helps to understand the structure and properties of that real network. There have been many algorithms with different approaches, including coordinating vertices and building appropriate distances between them. In this paper, a random walk has been used to coordinate the vertices of the graph and use the cosine of the angle between two vectors to detect network communities. The article also presents the Modularity function to evaluate graph clustering. Some experimental results on randomly generated graphs and graphs generated from the real data set Zachary's karate club network have been presented and compared with the K-means++ algorithm.

Building Nazi Germany
Authors: Hagen Joshua , Ostergren Robert C.
Published: March 2024

This richly illustrated book details the wide-ranging construction and urban planning projects launched across Germany after the Nazi Party seized power. Hagen and Ostergren show that it was far more than just an architectural and stylistic enterprise. Instead, it was a series of interrelated programs intended to thoroughly reorganize Germany’s economic, cultural, and political landscapes. The authors trace the specific roles of its component parts—the monumental redevelopment and cleansing of cities; the construction of new civic landscapes for educational, athletic, and leisure pursuits; the improvement of transportation, industrial, and military infrastructures; and the creation of networked landscapes of fear, slave labor, and genocide. Through distinctive examples, the book draws out the ways in which combinations of place, space, and architecture were utilized as a cumulative means of undergirding the regime and its ambitions. The authors consider how these reshaped spaces were actually experienced and perceived by ordinary Germans, and in some cases the world at large, as the regime intentionally built a new Nazi Germany.
Coming Climate Crisis?
Authors: Parkinson Claire
Published: March 2024

Decisively cutting through the hyperbole on both sides of the debate, distinguished NASA climatologist Claire L. Parkinson brings much-needed balance and perspective to the highly contentious issue of climate change. Offering a deeply knowledgeable overview of global conditions past and present, the author lays out a compelling argument that our understandings and models are inadequate for confident predictions of the intended and unintended consequences of various projects now under consideration to modify future climate. In one compact volume, Parkinson presents a coherent synopsis of the 4.6-billion-year history of climate change on planet Earth—both before and after humans became a significant factor—and explores current concerns regarding continued global warming and its possible consequences. She ranges over the massive geoengineering schemes being proposed and why we need to be cautious about them, the limitations of current global climate models and projections, the key arguments made by those skeptical of the mainstream views, and the realistic ways we can lessen destructive human impacts on our planet. While discussing all of these polarizing topics, the author consistently shows respect for the views of alarmists, skeptics, and the vast majority of people whose positions lie somewhere between those two extremes. The book clarifies some of the most contentious points in the climate debate, and in the process treats us to a fascinating discussion interweaving Earth history, science, the history of science, and human nature. Readers will be rewarded with a genuine understanding of a complex issue that could be among the most important facing humankind in the coming decades.
Christians in the Movies
Authors: Dans Peter E.
Published: March 2024

Christians in the Movies traces the arc of the portrayal in film of Christians from 1905 to the present. For most of the first six decades, the portrayals were favorable and even reverential. By contrast, from 1970 on, Christians have often been treated with hostility and often outright ridicule. This book explores this shift through in-depth reviews and commentaries on 100 important films, as well as briefer discussions of about 75 additional Christian-themed films.

Peter E. Dans examines various causative factors for this change such as the abolition of the Hays Motion Picture Production Code, the demise of the Catholic Legion of Decency, and the associated profound societal and cultural changes. From a look at the real story behind the Scopes trial to portraits of actors, directors and writers most prominently associated with films involving Christians and Christianity, Christians in the Movies provides a great resource for those who wish to select films for showing at churches, universities or for personal viewing and critical examination of the recent cultural movements and thought.
Samuel Adams
Authors: Alexander John K.
Published: March 2024

Samuel Adams: The Life of an American Revolutionary vividly tells the story of a titan of America's greatest generation. Friend and foe alike considered Adams one of the greatest members of the generation that achieved American independence and crafted constitutions that made the ideal of republican government a living reality in the new nation. Adams's role as a major political author and organizer are explored as is his central role in momentous events including the Boston Massacre and the Boston Tea Party. The work demonstrates why Thomas Jefferson described Adams as the helmsman of the American Revolution. Adams's career during the war and his involvement in crafting and defending republican constitutions are assessed as are his views on virtue, religion, education, women, and slavery. Following Adams through the 1790s, one sees that he wanted the revolutionary generation to bequeath a land of liberty and equality to the nation's posterity. The personal side of this revolutionary who was renowned for his lack of concern for material things is not neglected. The symbiotic relationship of Samuel and his wife Elizabeth is analyzed. The work demonstrates that Adams's life provides a veritable guide to responsible citizenship and public service in a republic.
Going Dirty
Authors: Mark David
Published: March 2024

Going Dirty is a history of negative campaigning in American politics and an examination of how candidates and political consultants have employed this often-controversial technique. The book includes case studies on notable races throughout the television era in which new negative campaign strategies were introduced, or existing tactics were refined and amplified upon. Strategies have included labeling opponents from non-traditional political backgrounds as dumb or lightweight, an approach that got upended when a veteran actor and rookie candidate named Ronald Reagan won the California governorship in 1966, setting him on a path to the White House. The negative tone of campaigns has also been ratcheted up dramatically since the terrorist attacks of September 11, 2001: Campaign commercials now routinely run pictures of international villains and suggest, sometimes overtly, at other times more subtly, that political opponents are less than resolute in prosecuting the war on terror. The book also outlines a series of races in which negative campaigning has backfired, because the charges were not credible or the candidate on the attack did not understand the political sentiments of the local electorate they were trying to persuade. The effect of newer technologies on negative campaigning is also examined, including blogs and Web video, in addition to tried and true methods like direct mail.

Muslim Worldviews and Everyday Lives
Authors: el-Aswad El-Sayed
Published: March 2024

el-Aswad introduces the concepts of worldviews/cosmologies of Muslims, explaining that the different types of worldviews are not constructed solely by religious scholars or intellectual elite, but are latent in Islamic tradition, embedded in popular imagination, and triggered through people's everyday interaction in various countries and communities. He draws from a number of sources including in-depth interviews and participant observation as well as government documents and oral history. Through the perspectives of ethno-cosmology, emic interpretation of sacred tradition, modernity, folklore, geography, dream, imagination, hybridity, and identity transformation, he examines how culturally and religiously constructed images of the world influence the daily actions of people in various Muslim communities. The worldviews of Sunnis, Shi'as, and Sufis are covered in turn, and Muslims in the UAE, Egypt, Bahrain, and suburban Detroit are the focus. el-Aswad also discusses the effects of Western attempts at imposing its essentially secular worldview through the process of globalization and how cyberspace has promoted connectivity among Muslim communities and, especially in the United States, opened up unlimited options and new possibilities.
Global Capitalism and Climate Change: The Need for an Alternative World System
Authors: Baer Hans A.
Published: March 2024

Many progressive scholars, particularly in the social sciences, have increasingly come to acknowledge that anthropogenic climate change constitutes yet another contradiction of global capitalism. This book constitutes an effort to develop a critical social science of climate change, one that posits its roots in global capitalism with its emphasis on profit-making, a treadmill of production and consumption, heavy reliance on fossil fuels, and commitment to ongoing economic expansion. It explores the systemic changes necessary to create a more socially just and sustainable world system that would possibly start to move humanity toward a safer climate and discusses the role of a burgeoning climate movement in this effort.
Advancements in Preventive Strategies and Enamel Regeneration: Navigating the Complexities of Dental Care in the Age of Technology
Authors: Galuscan Atena , Jumanca Daniela , Dumitrescu Ramona
Published: March 2024

In our technology-driven world, rising dental injuries have prompted re-evaluation of treatment methods. Key focuses include preventing carious lesions through early detection and good oral hygiene. Precise diagnostic tools enable tailored treatments, such as fluoridation, sealing, pH-adjusting diets, resin infiltration, and ozone remineralization. Dental enamel is crucial for tooth function. Researchers aim to replicate its complex structure for biocompatible materials. Hydroxyapatite’s unique properties are vital for hard tissues like bones, enamel, and dentin. Enamel development involves ameloblasts in pre-eruptive and post-eruptive stages. Saliva aids post-eruptive maturation but can lead to bacterial adhesion and enamel demineralization. Preventing enamel demineralization hinges on ion transport and critical pH levels, while low calcium levels impact enamel cells. Dietary sugars interact with bacteria, causing demineralization, but saliva aids remineralization. Caries risk depends on factors like diet, oral hygiene, and tooth morphology. Personalized approaches like Caries Management by Risk Assessment (CAMBRA) for caries risk assessment (CRA) are crucial. Traditional enamel protection methods involve fluoride and dental sealants, but concerns exist about fluoride toxicity and bacterial resistance. Modern alternatives include resin infiltration for early caries, argon laser technique for lesion protection, and ozone therapy to combat decay, offering noninvasive options for enamel care.

CICATRICIAL DEFORMITIES MANAGEMENT: A NARRATIVE REVIEW
Authors: Danishchuk Olga , Karpova Elena
Published: March 2024

Background: Treatment and prevention of the development of pathological scars (hypertrophic and keloid) is an important issue in modern dermatology and plastic surgery due to a violation of aesthetic perception (aesthetics), and in severe cases, the function of various areas of the human body.
The purpose of this systematic review of the literature was to analyze the proposed effective methods for treating scar deformities of the skin.
Methods: The systematic review included articles from Google Scholar, Medline, Scopus, Web of Sciences, PubMed. Search keywords terms included: pathological scar, therapy, botulinum toxin, laser, cryodestruction, hyaluronidase, skin scar prevention, new methods of wound treatment, wound and skin scarring, bioengineering surgery.
Results: Conducted a preliminary search and reviewed 132 titles and abstracts in this review and 50 full-text articles were selected of high methodological quality.
This review concluded the necessity of developing pre-surgical methods for preventing pathological scarring, which could potentially become a universal standard for any plastic and aesthetic surgery intervention. Treatment depends on the clinical and morphological characteristics of athological scars.
Conclusion: The current systematic review demonstrated the need to develop presurgical methods for the prevention of pathological scarring, which could in the future become a universal standard for any intervention in plastic surgery, since the issue of treating skin scars is sufficiently covered in the available world literature.

Published: March 2024

The field experiment was conducted in irrigated Alfisols of North coastal Andhra Pradesh tostudy the effect of biochar and chemical fertilizers on rhizosphere microbiome, soil enzymes andyield performance of groundnut crop (variety K-6) during rabi, 2018-19. Biochar application tosoil significantly increased soil bacterial, fungal and actinomycetes population. At pod developmentstage, the highest number of bacterial count (39.0 x106 CFU g-1 soil) was observed in T5 (100%RDF + biochar @ 6 t ha-1) which was on par with all the biochar applied treatments (T3, T4, T6, T7,T8). The Biochar applied @ 6 t ha-1 (T5 & T8) significantly increased the bacterial population ascompared to non-biochar applied treatments (T1 & T2). Fungal and actinomycetes populationfollowed the similar trend of bacterial count. Soil urease activity was significantly superior inbiochar applied treatments (T3, T4, T5, T6, T7, T8) compared to non biochar applied treatments (T1and T2). With increased rates of biochar application the urease activity markedly increased insoil. Similar trend was noticed with respect to dehydrogenase, acid phosphatase and alkalinephosphatase enzymes in soil in response to addition of biochar. At pod development stage, thehighest leaf area index (3.16) was recorded with 100% RDF + biochar @ 6 t ha-1(T5) which wassignificantly higher than T1 (control), T2 (100% RDF) and T6 (75% RDF + biochar @ 2 t ha-1). Thehighest drymatter accumulation of 2951 kg ha-1 at peg penetration and 6428 kg ha-1 at poddevelopment was observed in T5 (100% RDF + biochar @ 6 t ha-1) which was on par with T3(100% RDF + biochar @ 2 t ha-1), T4 (100% RDF + biochar @ 4 t ha-1), T8 (75% RDF + biochar @6 t ha-1) treatments. Groundnut pod yield was highest (4019.58 kg ha-1) in treatment received100% RDF + biochar @ 6 t ha-1, which was on par with T4 (100% RDF + biochar @ 6 t ha-1) and T8(75% RDF + biochar @ 6 t ha-1).
Assessing the Impact of Türkiye’s Unorthodox Monetary Policy on the Profitability of Unlicensed Solar Power Plant Projects
Authors: Arı İzzet , Kaya Mustafa
Published: March 2024

Türkiye’s unorthodox monetary policy implemented between September 2021 and June 2023 affected many macroeconomic indicators including inflation. Turkish Central Bank’s (CBRT) continuous lowering of the policy interest rate increased the negative real interest rate constantly. As a result, households invested in alternative assets including housing, foreign currency and gold in order to hedge against inflation. This increase in demand soared real estate prices. Besides, land is an important cost item for solar power plant investments. Considering the linear relationship between land prices and housing prices, this paper investigates the effect of the increase in housing prices on the capital expenditure (CAPEX) of 37 unlicensed solar power plant projects in Türkiye. According to the results, a correlation of -0.97 was determined between the real interest rate and housing price index in Türkiye. In addition, a correlation of 0.20 was found between housing price index and the CAPEX of unlicensed solar power plants. This situation indicates that the increase in housing prices primarily due to the unorthodox monetary policy might adversely affected the profitability of unlicensed solar power plants, since CAPEX is an important factor affecting the profitability. Although the unconventional monetary policy has been abandoned as of July 2023, the negative effects of this policy on the economy, especially inflation, still continue. Policies and practices that would increase the profitability of solar power plants will make significant contribution to the renewable energy investors and Türkiye's green transition. In this context, development and issuance of carbon development credits under the voluntary carbon market standards such as Global Carbon Council (GCC) Standard and International Carbon Standard (ICR) presents additionality to support solar power plant investors and help the country to reach her carbon neutrality target.

Published: March 2024

The standard analytical methods for the determination of total protein content, which is an important measure of quality in many food products, can be easily miss leaded by adding nitrogen deriving from different source driving to serious adulteration of the various foods. Therefore, there is an immense need to develop rapid method to detect multiple adulterations with handheld instruments. The objective of the present work is to develop multivariate models for simultaneous prediction of melamine and urea in wheat gluten samples with a handheld NIR scanner. Wheat gluten samples from ten different manufacturers from different part of the world were mixed with melamine and urea in different ratios to provide a robust enough sample set for spectral data acquisition. In spite of the natural separation based on the geographical origin of the gluten samples it was possible to build accurate models for simultaneous quantification of common food adulterants, melamine and urea, in multiple mixtures of gluten. The results show Tellspec Enterprise Food Sensor as a rapid, cost effective and user friendly tool can be used for the determination of melamine and urea adulteration in wheat gluten down to 1% concentration.
NIR-SWIR-Hyperspectral-Imaging supported surface analysis for the recovery of waste wood
Authors: Hollstein Frank , Pigorsch Enrico , Plinke Burkhard , Wohllebe Markus , Meinlschmidt Peter
Published: March 2024

Cascading of waste wood requires a concept for recovery of solid timbers from deconstruction as a source of clean and reliable secondary feedstock for new wood and wood-based products. An essential requirement for the re-use of wood is a sufficient quality of the near-surface areas that must be free of contaminations like coatings or any wood preservatives. Due to the absence of industrial established automatic testing and sorting methods the possible potential for material re-use of recovered wood in the sense of cascading is not utilized so far. Hyperspectral-Imaging (HSI) is a promising method to improve the situation. In the study on hand results according to detection accuracy and limitations of NIR-SWIR-HSI are presented. As input material solid waste wood (e.g. different kinds of hard wood, soft wood, wood with paint or other coatings, particle boards, and medium density fibreboards) obtained from deconstructions is considered. First, the spectral structures of some different kinds of wood and contamination are examined. Desired are the so-called fingerprints according to significant characteristics in the spectra. The results have been incorporated in a database as training set. For classification tasks some decision trees based on PLS-DA (Partial Least Squares Discriminant Analysis) were exploited. These decision trees are then passed to an industrial NIR-SWIR-Hyperspectral-Imager for generating chemical images of the contaminated wood samples. Results of some sorting experiments are presented. The aim of the tests was to find the limits for sorting throughput and purity. The tests revealed that the spectral differences are mostly large enough for automatic wood classification and sorting operations even at presence of inorganic wood preservatives. In this case the detectability and accuracy of classification depends much on preservative concentrations.

Authors: Grimmler Christina , Kuhfuss Tamara , Heiden Matthias , Schmitdt Heinar
Published: March 2024

To speed-up monitoring of the hygienic status of meat, fast and non-invasive measuring techniques are required. The feasibility of a hand-held fluorescence device (freshdetect) was investigated to quantify the bioburden of minced pork meat. In total, 144 minced pork samples from 18 batches were stored at 2°C for up to 8 days. Fluorescence spectra, L*a*b* colour and total viable mesophilic plate counts (TVC) were measured in parallel during this period. Correlation of the fluorescence spectra with log(TVC/g) using partial least squares regression yielded cross-validated predictions with R²cv = 0.72 and a prediction error of RMSECV = 0.97 log(TVC/g). Cross-validated limits of detection and quantification were determined as 1.03 and 3.38 log(TVC/g), respectively. This would allow for a quantification well below the alarm threshold of 5.7-6.7 log(TVC/g). The spectra correlated also well with storage time (R²cv = 0.81), but less strong with L*a*b* colour.
Optical identification of valuable materials on printed circuit board assemblies based on sensor fusion
Authors: Ruecker Johannes , Peper Patrick , Bochtler Ulrich , Klar Peter
Published: March 2024

Increasing waste of electrical and electronic equipment (WEEE) is a major challenge of today’s society. It affects society in several ways and needs to be solved to prevent loss of important materials and to reduce environmental contamination. Tackling this challenge requires affordable and reliable technological solutions, which enable recycling in a cheap and easy manner. One step to be taken is the recycling of printed circuit board assemblies (PCBAs), which are common in many of the high level devices such as computers or mobile phones. PCBAs include a huge amount of different components and thus belong to the most heterogeneous waste a recycler has to handle. The approach described in this paper is directed towards a reduction of the diversity by identification of specific components on the PCBA, which contain specific materials of interest. These components are then available for automated, selective disassembly. In this contribution classification results of a special descriptor developed for printed circuit boards are shown for three different classification algorithms. The descriptor is based on rather discriminative simple geometric and color features. The necessary data is obtained by a pilot setup, which is also described briefly, and processed withWaikato Environment for Knowledge Analysis (WEKA), a tool for processing big data.

Authors:   Department of ECE, S. V. University College of Engineering, Tirupati, Andhra Pradesh, India., Krishna Satish B
Published: March 2024

Wireless Sensor Networks (WSNs) are gaining prominence for diverse applications, including environmental monitoring and industrial automation. Yet, their energy constraint poses a significant challenge. Clustering, a prevalent technique, optimizes energy utilization by grouping nodes into clusters and appointing a cluster head (CH) to aggregate data and communicate with the base station (BS). This paper presents a novel clustering and CH selection algorithm for a energy varied WSNs, leveraging modified fuzzy c-means (FCM) clustering and Grey Wolf Optimization (GWO). Modified FCM partitions nodes based on their similarity, while GWO identifies CHs in each cluster, considering energy levels, centrality, distance from the BS, and dynamic node distribution. Simulation results demonstrate the superior energy efficiency and network lifetime of our proposed approach compared to existing algorithms.

Impact of Street Hawking on Children's Academic Wellbeing: A Critical Assessment
Authors:   Department of Public Administration, Kampala International University Uganda, Ugo Uche Samuel
Published: March 2024

Child street hawking is emerging as a significant public health concern in developing countries like Nigeria, primarily driven by poverty and resulting in the continuous migration of people to urban areas in search of livelihood. Despite existing legislation addressing child labor in Nigeria, the prevalence of street hawking persists due to inadequate implementation and enforcement. Moreover, traditional beliefs regarding children as contributors to the family's socioeconomic well-being further perpetuate this practice in African societies. Familyrelated factors also contribute to the involvement of children in street hawking. However, child hawkers face numerous hazards, including physical violence, loss of merchandise, accidents, robbery, kidnapping, and even murder for ritualistic purposes. They are also vulnerable to extreme weather conditions, insect and reptile bites, hunger, and deprivation. Of great concern is the risk of sexual exploitation and forced prostitution, leading to unwanted pregnancies and sexually transmitted infections. This paper examines the impact of street hawking on children's academic well-being and emphasizes the fundamental right of all children to receive basic education and quality learning opportunities. It underscores the need for legislation prohibiting street hawking by children, with legal repercussions for both parents and children involved in the practice. Prioritizing education and safeguarding children from the dangers of street hawking is essential for their holistic development and future societal contributions.

Authors: Kukesheva Aliya , Kadyrov Adil , Kryuchkov Yevgeniy
Published: March 2024

The purpose of the research in the article is to obtain analytical and experimental results on the purification of internal combustion engine exhaust gases by an electric pulse, allowing us to determine the main parameters of the muffler operation. The set goal was achieved by performing the following methodology. A mathematical model of the motion of a gas particle in a muffler has been developed and investigated, the relationship between the capacity of the engine combustion chamber, the number of revolutions of the crankshaft, the pulse intensity, and the dynamic viscosity of the medium has been established. The condition of the muffler operation is determined through the parameter - the distance between the electrodes. The optimality criterion is justified - the smokiness of the gas before and after purification. A nonlinear experimental plan has been compiled using the methods of similarity theory and dimension analysis. An experimental stand has been developed and results linking the process parameters have been obtained. The results obtained are the basis for the methodology for calculating the design of electric pulse mufflers with optimal smoke ratios.
Development of a FEM procedure for evaluating the pressure profile in the industrial wheel and fatigue strength analyses

Industrial wheels are heavily loaded components that undergo severe cyclic stress conditions. Thus, the design of the rims must include a wide fatigue study which articulates in laboratory and field tests, analytical and numerical analyses and comparison of the experimental and computational results. This paper presents the study approach applied in the study of a 25 in rim for earth-moving machines manufactured by Moveero. The rim was subject to a design update which provided the reduction of the thickness from 11 mm to 9 mm. We decided to study the interaction tire-rim because it's a critical zone. The failures affected the area of the seat radius of the fixed flange of the rim, which resulted to be the most stressed part of the rim because of the bending actions of the tire on the flange. In order to deepen the cyclic mechanical behaviour of the component, laboratory inflation and rolling tests were carried out in Woodridge USA considering several combinations of inflation pressure and radial load applied to the wheel. The strain data from the tests were analysed to develop a reverse empirical model for the contact pressure between tire and rim. Once the load diagram applied to the flange for each test was estimated, FEM static simulations could be performed on a 3D model of the rim through SolidWorks Simulation. The stress fields obtained were then used for fatigue FEM numerical analyses which could return an evaluation of the predicted life of the component under several load conditions.

Esta investigación pretende determinar en qué medida las actitudes frente a la pandemia por Covid-19 predicen el estrés en estudiantes de una escuela de formación policial de Trujillo. El presente estudio que utilizó el método hipotético deductivo, es de tipo básica, se trabajó con el enfoque cuantitativo, no experimental, de nivel correlacional predictivo y de corte transversal. La población estuvo constituida por 504 estudiantes de este centro de formación policial, cuyas edades oscilan entre los 18 y 25 años de edad, de la cual se extrajo una muestra de 288 estudiantes. Los instrumentos utilizados fueron el Inventario de reacciones de estrés y el Cuestionario de actitudes hacia la pandemia Covid-19. Los resultados demuestran que por cada unidad que mejore las actitudes frente a la pandemia, el estrés disminuirá (□-.44), ± .04, esta predicción es significativa (p<.001) y de magnitud grande (Z β= -.71). Las actitudes frente a la pandemia predicen un 51% de la variabilidad del estrés. La investigación concluye que las actitudes frente a la pandemia, predicen significativamente el estrés (p<.001), en un 51%; así como en sus dimensiones reacciones cognitivas (p<.001) en un 42%, reacciones fisiológicas (p<.001) en un 40%, y reacciones emocionales (p<.001) en un 43%.

The creation of a web-based application management system is essential to assist organisations in maintaining their operational efficiency in the rapidly growing digital era. The purpose of this research is to apply the waterfall development method approach to the development of a web-based application management system. We compared the time efficiency and features of a low-code platform such as OutSystems and traditional coding using native PHP. By streamlining procedures for recruitment, leave, warning or dismissal data, and human resource management, the system can improve overall operational effectiveness and efficiency. This research can provide in-depth information on the efficiency of development time and overall features. Our contribution is to clarify the performance comparison in the context of application management system development between low-code platforms and traditional development approaches.
Active hydrogen-controlled CO2/N2/NOx electroreduction:From mechanism understanding to catalyst design

Published: March 2024

The development of renewable-energy-powered electrocatalysis meets the need for the sustainable society. With water as the proton source, it enables efficient production of chemicals and fuels from renewable resources like CO2, N2, and NOx under ambient conditions. Hydrogen generated via water dissociation is a crucial participant in transforming reactants into desired products, but it also serves as a direct source of undesired reactions when in excess. In this review, we first present an overview of the functional mechanisms of active hydrogen in the electroreduction of CO2/N2/NOx. We then introduce a range of methods to enhance our understanding of these mechanisms. Furthermore, a detailed discussion of design strategies aimed at regulating active hydrogen in the reduction of CO2/N2/NOx is provided. Finally, an outlook on the critical challenges remaining in this research area and promising opportunities for future research is considered.

Potato leaf disease has mostly two categories; early blight and late blight disease. The disease may be more prevalent in certain weather patterns and have a catastrophic effect on potato crops. In summary, warm, humid weather with frequent rain or heavy dew, temperatures between 15°C and 20°C, and a lack of sunshine are the weather conditions that can cause potato late blight. Drier weather conditions favour early blight, unlike late blight. Warm and dry weather with a lack of rain or irrigation, temperatures between 21°C and 29°C, and high humidity in the morning are the weather conditions that can cause potato early blight. A modified dataset is used for climate-influenced prediction, and the testing accuracy using random forest models is 97%. Analysis of experimental results shows that the suggested potato-leaf disease prediction based on the weather data framework outperforms the outcome of frameworks.
