This work demonstrates the enhanced photocatalytic and antibacterial activities of copper and nitrogen-co-doped ZnO (Cu-N-ZnO) nanomaterials deposited onto soda-lime glass using a low-cost chemical approach. The effect of combined Cu-N doping is significant on the structure, properties, and performance of ZnO, as revealed from the characterization results. The synthesized materials crystallize in a hexagonal wurtzite structure of ZnO with a high degree of crystallinity, according to X-ray diffraction (XRD) experiments. The scanning electron microscopy (SEM) analysis indicated a uniformly distributed morphology with spherical-like ZnO nanoparticles. The optical studies revealed that the band gap decreases significantly in 5% Cu-5% N co-doped ZnO (2.89 eV) compared to intrinsic ZnO (3.36 eV). The photocatalytic and antibacterial activities of the samples were evaluated by the degradation of methylene blue dye in aqueous media and the inactivation of E. coli bacteria under visible light irradiation. The 5% Cu-5% N doped ZnO showed the highest dye degradation efficiency, which was 64.44% higher than that of the intrinsic ZnO and inactivated 62.53% more bacteria in the presence of light compared to that in a dark condition. Moreover, Cu-N co-doped ZnO inactivated 79.06% and 23.22% more bacteria than bare glass slides and ZnO under visible light irradiation, respectively.
Teljes körű kompetenciamérés és -értékelés a felsőoktatásban tanuláselemzési módszerek és technikák alkalmazásával
Authors:   , Meleg Ágnes
Published: July 2024

A kompetencia alapú megközelítés egyre nagyobb hangsúlyt kap mind a munka világában, mind az oktatásban, így folyamatosan nő az igény a kompetencia alapú értékelésekre, különös tekintettel a 21. századi készségekre, mint a kommunikáció és a csapatmunka. A kompetenciamérés azonban kihívást jelent, különösen igaz ez teljes körű – több kompetenciát egyidejűleg felölelő – értékelések esetében. A felsőoktatás hallgatói-oktatói aránya és a képzések széles palettája pedig tovább nehezíti a felsőoktatásban történő kompetenciamérést. Jelen kutatás újszerűsége abban rejlik, hogy – oktatásmódszertani elvek mentén, valamint a tanuláselemzés és oktatási adatbányászat módszereinek és eszközeinek segítségével – egy felsőoktatásban alkalmazható, olyan általános, teljes körű kompetenciamérésre tesz javaslatot, amely tantervbe beágyazott módon, kis erőforrással is kivitelezhető, emellett hidat képez a munka világa és a tanulmányi környezet között. A kutatási kérdések a következők: A) Hogyan lehet a hallgatókat valós munkahelyzetbe helyező egyéni kompetenciamérést hatékonyan végezni? aa) Hogyan biztosítható, hogy a képzés kimeneti kompetenciáinak (vagy elvárt tanulási eredményeinek) elsajátításáról átfogó képet kapjunk, anélkül, hogy minden kompetenciát külön módszerrel és eszközzel mérnénk? ab) Hogyan ellenőrizhető, hogy megbízható és az érintettek által világosan értelmezhető eredményeket ad-e a kompetenciamérés? B) Hogyan hasznosíthatók a kialakított kompetenciamérés adatai és eredményei? Az értekezés öt fő részből áll. Az első részben a probléma kifejtése mellett a kutatási keretrendszer és a kutatásmódszertan tárgyalására kerül sor. Ezt követően az A) kutatási kérdés kerül fókuszba. A második részben a kompetenciamérés és -elemzés elméletét és hátterét ismertetem. Majd az alkalmazott kompetenciamérést és annak kialakítását mutatom be. A negyedik részben a teljes körű kompetenciamérés értékelésének eredményeit részletezem. Végül a dolgozatot – a B) kutatási kérdéssel összefüggésben – a kompetenciamérés hasznosításának lehetőségei zárják.

Authors: Urfan Yunus , Akkoy Sevgi , Avşar Edip
Published: July 2024

With the development of technology in the 21st Century, changes have also occurred in the transportation sector. In recent years, transportation by ships at full capacity has increased the volume of maritime trade, causing unavoidable pollution in the seas. Today, maritime transportation is safe and encompasses various services and activities. Pollution caused by marine vessels is a significant concern for all over the world. In addition to this fuel costs were high because maritime transportation relied on simple, low-capacity vessels. The new vehicles used today pose a problem due to their low capacity. This article aims to identify the types and amounts of waste from new ships at the Tatvan Van Lake Ferry Pier and to develop strategies for transporting this waste to land within the framework of sustainable environmental management. The study suggests building a waste reception facility in the city to manage the waste generated by maritime activities.

Authors: Vélez Rivera Diego Andrés , Suárez Marín Carlos Alberto , Vargas Restrepo Carlos Mario
Published: July 2024

Este artículo identifica en qué grado la medición del Retorno social de la inversión (SROI) contribuye con la gestión eficiente de recursos, mediante una revisión sistematizada del término SROI. Este documento presenta una matriz de información cruzada de literatura científica que compara los hallazgos de estudios previamente realizados en diferentes sectores, teniendo en cuenta aspectos como enfoques metodológicos y objetivos de los análisis, campos en los cuales ha sido aplicada la herramienta, objetividad o neutralidad en relación con los involucrados; por último, reflexiona sobre la manera en la que se adaptaría el término a diferentes entornos. Es importante resaltar que aunque la herramienta conceptual y metodológicamente resulta eficiente y transparente para los tomadores de decisiones, en algunos casos su aplicación requiere de dominio profundo, pues los resultados obtenidos se derivan de intervenciones sociales (intangibles) que pueden ser difíciles de justificar.

Retratos em Azul: Identidade e nostalgia em Ten, Mitake (1995), de Naomi Kawase, e Blue Diary (1997), de Jenni Olson
Authors: Brazão Henrique
Published: July 2024

Pelo prisma da nostalgia e das formas de impressão de identidade através do dispositivo cinematográfico – como contributo para o campo dos estudos fílmicos – este artigo propõe o encontro de duas curtas-metragens: Ten, Mitake (1995), da cineasta japonesa Naomi Kawase, e Blue Diary (1997), da realizadora norte-americana Jenni Olson. Frutos de conjunturas culturais distintas, ambos são, contudo, filmes-ensaio oriundos da paisagem cinematográfica do final do século XX. A cor azul, que orienta as identidades visuais, textuais e simbólicas destes dois casos de estudo, é um lugar de união e diálogo, atuando como uma ponte e um gatilho sensorial. Expressivo e abundante nas composições visuais de Ten, Mitake, e pressentido ou ocultado em Blue Diary, o azul reflete estados de espírito e viabiliza um caminho para a interpretação destes dois objetos intimistas como um ponto de acesso aos seus universos privados.

A Geology of Film-fossils: The survival images across time and space in the digital era
Authors: Via Vázquez Valentin
Published: July 2024

This article explores the relationship between the concept of fossils and contemporary non-fiction cinema. Focusing on the space-time of cinema, materiality, and eco-feminism, in the attempt to represent the natural environment, the human being is no longer at the centre of the representation. Contemporary film subjects range instead from the stones’ iconography to the image’s survival, the archive, and its activation in the digital age. By analysing selected works by contemporary film-makers – Barbara Hammer, Deborah Stratman, Ana Vaz, Adrián Balseca, Eloïse Le Gallo, Julia Borderie and many others – this research aims to cover contemporary productions from an aesthetic and narrative perspective and see how new strategies are established to represent the natural world in the Anthropocene.
Três ideias para um geocinema em Werner Herzog
Authors: Macedo Lennon , Rocha Pereira Demétrio , De Borba Lucas Cássio
Published: July 2024

O artigo analisa a filmografia de Werner Herzog, sobretudo a mais recente (anos 2000 em diante), orientado pela hipótese de que essa filmografia aponta para um cinema da Terra, aqui nomeado geocinema. No que orienta um mapeamento de signos e ideias cinematográficas em filmes como O homem urso (2005), Encontros no fim do Mundo (2007), Visita ao Inferno (2016), Fireball (2020) e outros, tal hipótese consiste em perceber e tornar pensável uma sensibilidade acontecimental da obra herzoguiana acerca das catástrofes climáticas e das relações planetárias entre humanos e outros modos de existência. Esse pensamento geocinematográfico se faz notório a partir de três ideias audiovisuais: uma tensão entre o Pequeno e o Grande, com que a diferença de escala evidencia limites e potencialidades da relação entre o humano e o além-do-humano; um encontro com o acontecimento de Gaia, que torna visível a indiferença catastrófica da Terra para com a humanidade; um enciclopedismo perspectivista, que coleciona personagens atraídos por zonas abismais. As três ideias se traduzem à luz da filosofia de Gilles Deleuze e Félix Guattari, que descreve os atos de criação artísticos não a partir de sua materialidade fenomênica, mas de ideias, como de operações singulares de pensamento que povoam as obras. Assim, a análise dessas intensidades ideais leva a considerar que o pensamento geocinematográfico que permeia os filmes de Werner Herzog indica modos de conviver com a catástrofe desde uma ética sensível do acontecimento.

Developing social media training resources for AusAID scholarship students
Authors: Gruba Paul , Bettinson Mat , Mulder Jean , Grigg Gabrielle
Published: July 2024

Potentially, effective social media use has a valuable role to play in addressing a number of concerns for newly arrived international students including feelings of isolation, access to information and participation in community. The aim of this paper is to report on a project to develop social media training resources for AusAID students from developing countries. The project was delivered as part of a six-week, 100-hour introductory academic preparation program. Using an action research approach, we conducted three stages of materials production, data gathering and self-reflection. In our overall analysis of the project, we identified resistance to participation, information overload and technological impediments as central barriers to full integration of social media training. We conclude with suggestions for improvement and research in the development and integration of social media training resources.
Do 21st Century Students Dream of Electric Sheep?
Authors: Cochrane Thomas , Withell Andrew
Published: July 2024

Students sometimes appear to be 'asleep' and are often updating their Facebook status during seminars and lectures. We argue this is the equivalent of counting electric sheep. Student brainwave activity measured during traditional lectures has been shown to be similar to that while watching television and significantly lower than that exhibited during any form of activity including sleep (Mazur, 2012). Mazur found that introducing interactive activities in lectures significantly increases brain activity. In this paper we explore the potential for mlearning to enhance student interactivity and collaboration both in the classroom and in authentic situated learning contexts. We partnered with Vodafone New Zealand and Auckland Transport to provide our students with an iPad Mini, and 4G connectivity, to enable student-generated research projects. The students' brief was to design an enhanced experience of commuting via public transport in Auckland City. Thus the research investigates how mobile devices can be used enable interactive learning environments.
Business student's attitudes to criteria based self- assessment and self-efficacy
Authors: Carroll Danny
Published: July 2024

Reducing student passivity and designing reflective skills into tasks contributes to developing student's professional judgment capabilities (Boud, 2000). This study analyses Business student attitudes and practices related to self-efficacy, self-regulation, assessment and self-assessment in two courses where students practiced criteria level self-assessment. A survey instrument was developed and an exploratory factor analysis in both sampled groups showed broad consistency in factor identification and reliability. Both cohorts' evidenced similar presentations related to self- efficacy, positive associations with socially mediated learning and a positive attitude towards developing better professional judgment. Student's confidence in their ability to understand task level requirements and instructions was greater than their confidence in their ability to accurately judge against criteria. A significant number of third year undergraduate students reported they had few opportunities to do self-assessment activities as part of their degree. This highlights the need to better integrate self-assessment practice into our Program design.
Evaluating an institutional blended & mobile learning strategy
Authors: Russell Carol , Jing Qi
Published: July 2024

The University of Western Sydney is investing in three levels of learning technology provision: institutional, academic-led and student-led. A new strategy launched in 2012 included infrastructure and software upgrades, recruitment of more staff to assist in blended curriculum design within disciplines and, from 2013, the issue of iPads to all new undergraduate students and to teaching staff. This paper describes how these initiatives are being evaluated, to gather evidence of the initial impact of the investment on the student learning experience and on the capacity of staff to provide quality teaching and curricula.

Recommendations for future opportunities are also proposed.
Designing learning spaces in higher education for autonomy
Authors: Parisio Martin
Published: July 2024

Learner autonomy underpins many of the educational outcomes at university such as flexibility, adaptability, self-initiative and self-direction. Indeed, learner autonomy is a key to life-long learning. This paper reports on research investigating the ways designers of innovative learning spaces incorporate customisable, (re)configurable and flexible features that support and encourage learner autonomy. The research aims to elicit high-level design principles that may prove useful in design for learning more generally - including design for learning in virtual and hybrid (physical and virtual) spaces. The research involved seventeen learning spaces across eight universities, observations and interviews with educational stakeholders, and architects and interior designers of those spaces. Preliminary findings suggest designers aim to empower students by providing configurable spaces fitted out with modular furniture and ubiquitous technology - emphasising choice. The paper ends by reviewing the application of these design ideas to broader problems and opportunities in 'design for learning' research and practice.
Augmenting learning reality
Authors: Oldfield James , Herrington Jan
Published: July 2024

In the three short years since the release of the iPad, it has become the object of substantial investment in a number of areas of education. This investment is driving the need for significant research into mobile device related teaching and pedagogy. The focus of this paper is on the first iteration of a design-based research study, which is informed by theories of authentic learning, cognitive tools and mobile learning. This paper is an introductory exploration into the use of iPads, and the apps and services they run, as cognitive tools in an authentic tertiary learning environment. This paper highlights a range of iPad apps and Web 2.0 services used in the study, and methods for their potential use to augment the learning experience in a business education context.
Dreams, hiccups and realities
Authors: Northcote Maria , Christian Beverly
Published: July 2024

Negotiating curriculum design with students for students involves incorporating both the students' needs and the lecturers' requirements into the course structure, learning activities, resources and assessment tasks. In 2012, two lecturers and a group of first year undergraduate students worked together to design an online module within an on-campus course for a second year teacher education degree. During the semester when the online module was conducted, data were gathered from the lecturers and students in the course. Findings from analyses of these data are presented in this paper in terms of: 1) the lecturers' and students' initial dreams and plans when the online module was co-designed; 2) the hiccups and problems encountered during the online module; 3) the realities of the successful aspects of the online module; and 4) the lessons learned for future emergent and negotiated curriculum design practices in higher education contexts.
Understanding the use of smart mobile technologies for learning in higher education
Authors: Murphey Angela , Farley Helen , Koronios Andy
Published: July 2024

This paper presents a preliminary exploration of the types of smart mobile technologies higher education students have access to and use to support their learning by comparing cohorts from two Australian universities with quite different profiles, the University of Southern Queensland (USQ) and the University of South Australia (UniSA). These results are briefly compared to those obtained in earlier studies in a broad attempt to identify trends in the use of mobile technologies to support learning over time. The results indicate that levels of smart phone ownership are rising rapidly with a corresponding drop in levels of feature phone ownership. Tablet computers such as iPads have emerged since the earlier studies were completed with high levels of adoption by students. Significantly, students are using these smart mobile devices to support their learning.
Issues Integrating Remote Laboratories into Virtual Worlds
Authors: Machet Tania , Lowe David
Published: July 2024

Laboratory work in education has long been recognised as providing real benefits to students. Increasingly, remotely accessible laboratories are being used for laboratory work in the sciences and engineering, providing students with remote access to real equipment while delivering additional benefits to institutions. There is an increasing focus on how these labs may improve laboratory learning outcomes. One potential enhancement, resulting from their mediated interface, is the ability to add contextual information to a laboratory activity. Virtual worlds have been identified as a rich environment for providing contextual information. However, the reported examples of real equipment laboratories integrated into a virtual world are specific to the laboratory. This paper describes a more generic approach to interfacing a virtual world, Open Wonderland, to laboratories which use the MIT iLabs platform. The paper reports on the issues involved in the interface and the strengths and limitations of this system.
The IRAC framework
Authors: Jones David , Beer Colin , Clark Damien
Published: July 2024

It is an unusual Australian University that is not currently expending time and resources in an attempt to harness learning analytics. This rush, like prior management fads, is likely to face significant challenges when it comes to adoption, let alone the more difficult challenge of translating possible insights from learning analytics into action that improves learning and teaching. This paper draws on a range of prior research to develop four questions - the IRAC framework - that can be used to improve the analysis and design of learning analytics tools and interventions. Use of the IRAC framework is illustrated through the analysis of three learning analytics tools currently under development. This analysis highlights how learning analytics projects tend to focus on limited understandings of only some aspects of the IRAC framework and suggests that this will limit its potential impact.
Transmedia in English Literature Classes
Authors: Griffith Michael , Bower Matt
Published: July 2024

This paper is the beginning of a research project which will explore the function and impact of Transmedia (TM) in Higher Education (specifically English Literature studies). There are several underlying assumptions that are being tested about the range of benefits to students of using this technology. These include: that TM deepens student understanding of the nature of creative expression (including literature); that TM deepens student engagement with the traditional literature they have been studying; that TM releases students' creative expression; that TM provides students with insights into the extraordinary creative power of digital technologies; that TM deepens students' sense of community (both within and beyond class).
Machinima for immersive and authentic learning in higher education
Authors: Gregory Brent , Gregory Sue , Gregory Myee
Published: July 2024

The use of virtual worlds have been well documented as a space for immersive participation by students when learning authentic tasks that can be difficult, if not impossible, to undertake in the real world. They have also been used in order to grasp important concepts through machinima (inworld video). A pilot project, "computers@armidale", explores the use of machinima to explain important concepts in a first year accountancy degree. Often, these concepts are difficult to grasp without taking students through authentic learning tasks. This paper describes the learning concept, the creation of the machinima and how it is used with first year accountancy students through a think out loud protocol.
Prospects for iPad apps and learning design in medical education
Authors: Dalziel Bronwen , Dalziel James
Published: July 2024

Educators are expected to keep up to date with the variety of new technologies that are available for teaching and learning. However, not all technologies will automatically increase a student's higher order thinking skills without the teacher carefully planning how the technology will fit into the educational context. It is through 'designing for learning' that a teacher conceptualises how emerging educational theories and practices can encourage students to take deep approaches to their learning. Tablet devices are increasingly being used in education, but using stand alone educational apps, which usually focus on a specific educational need, poses a potential limitation to good learning design based on scaffolding of multiple activities. This paper explores a theoretical model of how a learning design system (such as the Learning Activity Management System - LAMS) can be used to create app-based learning designs, specifically in a medical context.
Dynamic digital posters
Authors: Cook Roger , Fenn Paul
Published: July 2024

Academic and professional staff at Queensland University of Technology (QUT) have been faced with the challenge of how to create engaging student experiences in collaborative learning spaces. In 2013 a new Bachelor of Science course was implemented focusing on inquiry-based, collaborative and active learning. Student groups in two of the first year units carried out a poster assessment task. This paper provides a preliminary evaluation of the assessment approach used, whereby students created dynamic digital posters to capitalise on the affordances of the learning space.
Re-imagining the university
Authors: Al-Mahmood Reem
Published: July 2024

This paper invites a re-imagining and re-envisioning of 'the university' in its being and becoming (Barnett, 2011a, 2011b, 2013).The paper explores 'feasible utopias' (and dystopias) for the university and moves to provoke and promote 'radical' paradigms that are more inclusive of everything. The ideal of the 'ecological university' (Barnett, 2011a) is used to unfold three 'radical' paradigms that embrace object-oriented ontologies (through Actor-Network Theory), affectivity (through Non-Representational Theory) and (im)mobilities (through the new mobilities paradigm). The paradigms are intertwined and illustrated through a selection of e-learning vignettes drawn from a larger Australian university ethnographic study of four fully online postgraduate subjects to show how the various sociomaterial affective networks enact different experiences and perceptions of 'the university'. This is an invitation to dream - that we might imagine enriched accounts of the world that embrace vibrant matter(s) for 'feasible' university utopias.
Verification of Three-dimensional Numerical Study of Scour in Channel, Sudden and Gradual Contractions using Experimental Data

This paper presents a verification of a numerical and experimental simulation of scour patterns at channel contractions using a 3-dimensional SSIIM (Sediment Simulation in Intakes with Multiblock option) model and laboratory tests. For this purpose, two states of sudden angle¬-90° and gradual angle -50° contraction were simulated. The numerical model was calibrated and verified using the laboratory data. The accuracy of the model was calculated as 0.936 based on the Nash-Sutcliffe model efficiency coefficient, and 10.18% based on the mean relative error. Results showed that around 80% of scouring occurred during the first 20% of the equilibrium time. Also, it was concluded that the maximum rate of scouring occurred during the first hours of experiments and computations, and decreased with time. The results showed that the average scour rate for the sudden contraction state was 29.5% greater than the gradual state, which indicated a positive impact of gradualness of conversion in reducing maximum scour depth. This is an appropriate performance of the numerical model to simulate the scour pattern in channel contraction.

Comparison of modeling methods for the effective diffusivities of IO3
− estimated in compacted bentonite using through-diffusion tests under aerobic conditions
Authors: Tsai Tsuey-Lin , Tsai Shih-Chin
Published: July 2024

Diffusion is the predominant mechanism governing the transport of 129I through geosphere. Consequently, the assessment of the experimental findings on two-compartment diffusion reservoirs of IO3
− within compacted bentonite involved the application of three distinct diffusion models: CC–CC (constant concentration), CC–VC (variable concentration), and VC–VC. To ensure the reliability of the obtained diffusion coefficients, multiple laboratory tests were performed for internal comparison. The experimental results revealed that IO3
− diffusion coefficients were ranging from 3.83 × 10−13 to 1.91 × 10−11  m2/s. These techniques using three mathematical models could be conducted to estimate the diffusion coefficients of non- or weakly-sorbing radionuclides on compacted bentonite for safety assessment of radioactive waste final disposal.

Introduction

Acute appendicitis (AA) is the predominant condition responsible for acute abdominal pain across all age demographics. The purpose of this research is to determine if the hemoglobin, albumin, lymphocyte, and platelet (HALP) and modified HALP (m-HALP) scores differ between complicated and uncomplicated appendicitis in patients diagnosed with AA who have applied to the emergency department (ED). Additionally, this study aims to investigate whether HALP and m-HALP scores are superior to other biomarkers.

Materials and methods

The retrospective analysis included adult patients, aged eighteen or older, who were diagnosed with AA, and sought treatment at the ED of a tertiary hospital. Patients were divided into two groups: complicated appendicitis (CA) and uncomplicated appendicitis (UCA). The cut-off in diagnostic value measurements was determined using the receiver operating characteristic analysis.

Results

A total of 436 patients (CA: 126, UCA: 310) were included. Neutrophil-to-lymphocyte ratio (NLR), neutrophil-to-albumin ratio, systemic immune-inflammation index (SII), systemic inflammation response index (SIRI), and pan-immune inflammation value (PIV) were found to have acceptable diagnostic power in CA detection (area under the curve [AUC]: 0.735–0.783). In detecting UCA, HALP and m-HALP were of fair diagnostic power (AUC: 0.64, 0.68, respectively).

Conclusions

In this study, we found that although PIV, SIRI, SII, and NLR had acceptable diagnostic values in distinguishing CA and UCA, HALP and m-HALP had fair diagnostic values.
A novel method for constructing large-scale industrial noise maps based on open source data
Authors: Wang Yubin , Lee Hsiao Mun
Published: July 2024

This study proposed a method of obtaining the type and quantity of equipment in factories by inquiring environmental impact assessment reports, which greatly improves the efficiency of gathering factory information. Thereafter, by combining on-site measurement and numerical modelling, the noise maps of an automobile industrial area were constructed. The exposed population under different noise levels were evaluated using the noise maps. The results indicated that noise pollution at nighttime in the study area was more severe than that during daytime, with 523 people (1.08%) and 1,357 people (2.81%) exposed to excessive noise levels during daytime and nighttime, respectively. In addition, this study also constructed a low-frequency industrial noise map. The methods and results of the present study can provide novel technical path for construction and analysis of large-scale industrial noise map.
Effect of the gravitational field strength on the rate of chemical reactions
Authors: Wasif Baig Mirza
Published: July 2024

The magnitude of the rate of chemical reactions also depends on the position in the gravitational field where a chemical reaction is being carried out. The rate of chemical reaction conducted at a stronger gravitational field, i.e., near the surface of some heavy planet, is slower than the rate of reaction conducted at a weaker gravitational field, i.e., away from the surface of a heavy plant, provided temperature and pressure are kept constant at two positions in the gravitational field. The effect of gravity on the rates of reactions has been shown by formulating the rate constants from almost all types of reaction rate theories, i.e., transition state theory, collision theory, Rice–Ramsperger–Kassel–Marcus, and Marcus’s theory, in the language of the general theory of relativity. The gravitational transformation of the Boltzmann constant and the energy quantum levels of molecules have been developed quantum mechanically. A gravitational transformation of thermodynamic state functions has been formulated that successfully explains the quasi-equilibrium existing between reactants and the activated complex at different gravitational fields. Gravitational mass dilation has been developed, which explains that at weaker gravitational fields, the transition states possess more kinetic energy to sweep translation on the reaction coordinate, resulting in the faster conversion of reactants into products. The gravitational transformation of the half-life equation shows gravitational time dilation for the half-life period of chemical reactions and thus renders the general theory of relativity and the present theory in accord with each other.

Generation Z as digital natives are distinguished by their intense engagement in online activity. This article is an analysis of the impact of the internet use on academic performance in Gen Z based on data from the China Family Panel Studies (CEPS) 2020. Research findings show that there exist divides in the internet use among members of Gen Z with distinct family origins and that the impact of the internet use on students’ academic achievement varied according to their educational phases and prior academic rankings. The multi-categorical ordinal logistic regression model was adopted in the analysis.
RESETTLEMENT ADMINISTRATION HANDBOOKS: CREATION, CONTENT, DISTRIBUTION, READING (LATE 19TH – EARLY 20TH CENTURY)
Authors: Чупин М.Ю.
Published: July 2024

В фокусе исследования автора находятся малоизученные проблемы создания и бытования справочников, которые Переселенческое управление издавало для крестьян в конце XIX – начале XX в. Установлены авторы, тиражи и механизмы распространения такого рода книжной продукции. За несколько десятилетий сложились целые серии справочных изданий, которые предоставляли переселенцу детальную информацию о регионах Азиатской России в текущем году. Со сменой переселенческого курса от сдерживания к поощрению репрезентация Сибири становилась все более позитивной. Вместе с тем справочники не были рекламным изданием, так как в них содержались разносторонние (в том числе негативные) сведения о Сибири. Их можно считать одним из ограниченно эффективных каналов информирования. Тиражи и механизмы, компенсировавшие грамотность, делали справочные книги доступными, но действенность их распространения остается неясной. Кроме того, крестьяне могли воспринимать содержание справочника в искаженном виде и не доверять официальной информации.

The study focuses on the understudied problems of creation and use of handbooks published by Resettlement Administration for peasants in the late 19th and early 20th centuries. The first official publications for informing settlers were issued by Resettlement Administration. Comparison of the handbooks of different years shows how the system of information collection developed and how the representation of Siberia changed. A series of handbooks about Asiatic Russia emerged over several decades, as well as their short versions, and handbooks about resettlement areas. They provided the settlers with detailed information about the regions of Asiatic Russia in the current year. The representation of Siberia became more positive with the change of the resettlement course from deter to encouragement. The compilers of handbooks, their print runs, and the mechanism of their distribution are identified. Generally, the compilers of handbooks were experienced and high-ranking officials, some of whom were engaged in scientific activities. The purpose of the handbooks was not advertising, but informing peasants about the difficulties and prospects of resettlement. It is complicated to establish with certainty what influence the handbooks had on the settlers. At most, they can be considered a limitedly effective source of information. The annual circulation corresponded to the number of settlers, with some years being exceptions. However, it is not clear whether the mechanism of distribution of handbooks allowed to bring the publications to the reader. The literacy level of peasants was low, but there were compensatory mechanisms, such as collective reading aloud, assistance of officials and zemstvo workers. It is possible that a significant factor that reduced the effectiveness of handbooks was that peasants misunderstood them and might not have trusted official information.

Space Pollution metals contributing to Ozone Hole, South Atlantic Anomaly, and Radiation Belt
Authors: Lutz Kole
Published: July 2024

Since the 1970s, ozone (15-40 km) over Antarctica has continuously declined, which parallels the time of metallic satellites from the 1960s-2000s and discovery of Inner Radiation Belt (IRB). This is the first study to suggest heavy metals from satellites, debris, & rockets are correlated to Inner Radiation Belt (IRB), South Atlantic Anomaly (SAA) and Ozone hole and to propose the North Atlantic Anomaly (NAA). After high temperature corrosion (HTC) for <45 min sunward in Low Earth Orbit (up to 125C or 270F) and during re-entry, metals (Al, Fe,Mn,Ce,Pb) from satellites become ionized with high charges(+3,+2) and form metal oxides such as (Al2O3, Fe2O3,etc), metal hydroxides(Al(OH)n, Mn(OH)n, etc) until deposition as oxides, sulfides, and silicates. For example, after big reentry events such as 75-ton Skylab EDL fell to Earth in 1979, McConnell et al.,1 recorded 40X increase in metals such as Al, Pb in ice in Antarctica with other studies finding Pb of 1000X+ and Cd of 10X+ in 1980s. If SAA 3D Vortex and Radiation Belt co-located at ~200-500 km with trapped ionized particles and metals, heavy and light ion fluxes near poles would form metal oxides, ozone hole and reduce magnetic B-field, which may have formed largest ozone holes measured. Similar to how CFC atoms react with ozone, this study discusses how transition metals are a primary factor contributing to ozone depletion, metal oxides & silicates formation, observed in South America and Antarctica, which coincides with widespread desertification, extinctions, and warming. If metals from satellites in SAA deposit to poles with 2-16X heat absorption capacity to melt ice and radiation over poles, this could be a primary force melting ice in Polar Regions.
Effect of gestational diabetes on the eye: a mini review
Authors: Garg Pragati , Sinha Parul
Published: July 2024

Gestational diabetes mellitus (GDM) is a condition characterized by glucose intolerance that is first recognized during pregnancy. This condition affects a significant number of pregnancies worldwide, with an estimated prevalence ranging from 1% to 14% depending on the population and diagnostic criteria used.1,2 GDM accounts for 90% of diabetes mellitus cases in pregnancy, while pre-existing type 2 diabetes accounts for 8% of such cases.2 While gestational diabetes often resolves after childbirth, it can have profound short- and long-term implications for both the mother and the baby. One of the critical areas of concern is the impact of gestational diabetes on ocular health. This article is based on the effects of gestational diabetes on the eyes, the mechanisms involved, potential complications, and management strategies.
