A kínai „adósságcsapda-diplomácia” kritikus megközelítése: egy mém térnyerése
Authors: Brautigam Deborah
Published: May 2024

2017-ben egy észak-indiai agytrösztben megszületett a kínai „adósságcsapda-diplomácia” mémje. Ez villámgyorsan elterjedt a médiában, a hírszerzői körökben és a nyugati kormányok között. 12 hónappal később a mém 0,52 másodperc alatt már közel 2 millió keresési találatot generált a Google-on, és elkezdett mély történelmi igazsággá szilárdulni. A történetek igazságokat és valótlanságokat is tartalmazhatnak, az emberi érzelmek, köztük az előítélet pedig bizonyos gondolkodási módra sarkall minket. Ez a tanulmány egy sor olyan történetet mesél el újra Kína nemzetközi szerepvállalásáról, többek között Angolában, Dzsibutiban, Srí Lankán és Venezuelában, amelyek megkérdőjelezik a média csúsztatásait. A cikk néhány javaslattal zárul a tudományos élet, a média és a politika világa közötti kapcsolatról, valamint arról, hogy a kutatóknak ki kell mondaniuk az „igazságot” a „hatalom” felé. A mém egy olyan ötlet vagy gondolat, amely egy kultúrán belül személyről személyre terjed, gyakran azzal a céllal, hogy valamilyen jelenséget, témakört, vagy jelentést közvetítsen. 2017. január 23-án egy észak-indiai agytröszben született meg a kínai adósságcsapda-diplomácia mém, melyet aztán továbbvitt egy, a Harvard két hallgatója által írt tanulmány, mely az „adósságkönyv-diplomácia” kifejezést használta a jelenségre. A diákok írását a Guardian, a New York Times és más vezető sajtótermékek lelkesen idézték mint Kína aljas szándékainak tudományos bizonyítékát. A mém Washingtonban kezdett mély gyökeret verni, az amerikai kormányzaton keresztül Japánba került, majd vissza a New York Times-ba és számtalan további helyre. Később a mém még nagyobb népszerűségre tett szert, már az amerikai külügyminiszter is hivatkozott rá, csendesen begyűrűzött hírszerzési körökbe, megjelent az amerikai Kongresszusban, és megtelepedett a Pentagonban. Az „adósságcsapda-diplomácia” gondolata, és konkrétan a mém komoly aggodalommal töltötte el ezeket az embereket. 2018 novemberére egy Google keresés a fogalomra [angolul - a szerk.] 0,52 másodperc alatt 1 990 000 találatot generált. Az adósságcsapdamém elkezdett megszilárdulni mint közhiedelem, és elkezdték valós történeti igazságként kezelni. Ez a tanulmány a kínai „adósságcsapda-diplomácia” mémjét vizsgálja meg, mely azt állítja, hogy Kína szándékosan igyekszik adósságcsapdába csalni az országokat, hogy stratégiai előnyt, vagy valamiféle eszközt biztosítson magának. Az írás megvizsgálja a mém felemelkedését, elterjedését, és a mögötte húzódó jelenséget, amelyet a mém meg akar ragadni. A tanulmány ezenkívül egy tágabb kontextust is kínál azáltal, hogy újra elmeséli a kínai hitelezés legismertebb mítoszait és narratíváit, melyek olyan dolgok magyarázatára szövődtek, amelyeket a megfigyelők sem értenek tisztán.
Megszakadt kör: Korai dezindusztrializáció, kínai tőkeexport és az új ipari komplexumok botladozó fejlődése
Authors: Neel Philip
Published: May 2024

Az ipari fejlődést és a közvetlentőke-befektetések (FDI) szerepét leíró hagyományos modellek az urbanizációt és az ipari termelés növekedését a foglalkoztatás iparosodásával társítják. Mindezzel azt sugallják, hogy a szolgáltatás-alapú munkaerőpiacra való átállás a fejlődés „érettségének” jele, viszont ezek a modellek nem adnak magyarázatot a „korai dezindusztrializáció” tendenciájára, amely a szegény országokban világszerte egyre nyilvánvalóbb. Ezek a modellek nem számolnak a termelés és foglalkoztatás, a formalitás és informalitás, az indusztralizáció és urbanizáció mély szétválásaival, amelyek a világ leggyorsabban fejlődő városaiban figyelhetőek meg. Eközben a kritikai fejlődéselméletek alternatív modelljei az iparosodás felelmelkedésének kudarcaira és a klasszikus függőségi viszonyokra fókuszálnak, amelyek közül egyik sem magyarázza a manapság megfigyelhető jelenséget. Jelen tanulmány alternatív magyarázatot ad a korai dezindusztrializációra, a technikai fejlődés és a kapitalista fejlődés szekuláris tendenciáinak marxi elméleteiből kiindulva. Az érvelést a szerző a tanzániai Dar es-Salaamban és a kínai Gyöngy-folyó deltájában végzett terepmunkájából vett példákkal illusztrálja. Ennek mentén a korai dezindusztrializáció jelensége azt sugallja, hogy a fejlődés köre a saját ellentmondásai alatt omlik össze, még mielőtt az iparosítás körbekerülhetné az egész bolygót.

Published: May 2024

Millifluidic plant-based caviar generator was investigated. Effects of parameters; continuous phase flow rate, dispersed phase flow rate, and dispersed phase aperture diameter on the equivalent diameter, degree of spherical shape, and generation rate in a coaxial airflow alginate droplet generator were examined using a computational fluid dynamics (CFD) simulation program. A 2D planar simulation together with the volume of fluid (VOF) was applied to describe the phenomenon of droplet generation. Results showed that increasing the continuous phase flow rate yielded a decrease in equivalent diameter but an increase in droplet generation rate and an increase in the degree of spherical shape. Increasing the dispersed phase flow rate yielded a decrease in the degree of spherical shape but a significant increase in the droplet generation rate as well as a slight increase in equivalent diameter. Increasing the dispersed phase aperture diameter yielded an increase in equivalent diameter but a decrease in droplet generation rate and degree of spherical shape. Overall, the device could generate from 1,400–9,000 drops per hour with around 2.3–4.0 mm in size.

A blended learning model and a design model combine to support academics in pedagogical redesign of the curriculum
Authors: Pannan Linda , Legge Katherine
Published: May 2024

Mostly, blended learning is simply interpreted as the combination of face-to-face and computermediated learning (Graham, 2006). Unfortunately, this definition not only hides the complexity and transformative possibilities of blended learning, it can also leave the academic teaching developer without the detail and certainty they need to develop learning designs that address their institution's blended delivery expectations and meet their students' learning needs. Our approach to supporting academic change to blended learning addresses these uncertainties and places emphasis on the pedagogic strategies that guide student learning activity and drive the design of integrated learning experiences across learning environments. We present two models - a four phase blended learning model and a two-layer design model, and demonstrate how the properties of each combine to afford a blended learning design approach. Early indications of its effectiveness are promising and favourable responses to the model's simplicity and use indicate they may support teaching developers across other contexts.

Published: May 2024

Descriptions of cross-institutional, educational technology development initiatives that emphasise what actually works in real-world classrooms are rare. In this paper, we describe a multiinstitution collaboration that grew from grassroots classroom needs and proved resilient in the face of institutional change. We explain how the initiative came about, how it survived unanticipated change, and how it led to the development of a new open source learning analytics tool for student engagement. We provide some reflections on the first pilot study of the tool and describe future plans. The authors welcome new collaborators and invite interested readers to evaluate and extend the tool for themselves.
Deakin Hallmarks
Authors: Jorre de St Jorre Trina , Johnson Liz , Oliver Beverley
Published: May 2024

Graduates need to be able to articulate and evidence their capabilities in order to secure or create opportunities for meaningful work (Oliver, 2013). Therefore, students should be made aware of the capabilities required in the workplace and encouraged to actively integrate learning experience from their coursework with learning and achievements from other aspects of their lives. However, getting students to engage with graduate capabilities and think ahead about employment is a challenge. Deakin Hallmarks are an extra-curricular work-integrated assessment strategy designed to give students the opportunity to differentiate themselves to employers by recognising outstanding achievement through digital credentials. Here we report on the design principles and processes developed to ensure that they warrant meaningful achievement in the workplace; and encourage students to become aware of the capabilities they will require specific to their intended career.
A Strategic Response to MOOCs
Authors: Brown Mark , Costello Eamon , Giolla-Mhichil Mairead
Published: May 2024

This paper asks the question what role should governments play in supporting a strategic response to the Massive Online Course (MOOC) movement? It describes the growth of MOOCs in Europe and reports on the Irish experience as a case study to discuss whether or not a more formal policy response is required to harness the potential of new models of open and online learning to promote wider access to higher education. Ireland is used to illustrate how different institutions have chosen to respond to MOOCs by tracing the history of several first generation initiatives. The response of government agencies and policy-makers is then discussed in the context of a number of high-level policy initiatives. Set against the backdrop of a lack of serious policy engagement in the development of MOOCs, the paper concludes by explaining why Dublin City University (DCU) has chosen to launch Ireland's Open Learniung Academy.
Confidence drives exploration strategies in interactive simulations
Authors: Arguel Amaël , Lodge Jason , Pachman Mariya , De Barba Paula
Published: May 2024

Maximising the benefits of digital learning environments requires understanding how students process what they are exposed to in these environments. Besides approaches based on examining information processing within the cognitive domain, the importance of including emotions has been recently addressed. This study aimed to explore emotional dynamics during discovery learning in an interactive simulation, with continuous measures of self-reported confidence and challenge. Interactions from participants were recorded and two groups were created according to the exploration strategy used: systematic or non-systematic. Visual exploration was also measured by eye tracking as well as knowledge at pre- and post-test. Results suggest that learners using a systematic exploration strategy ran significantly more simulation cycles than non-systematic learners. Moreover, the latter group reported to be significantly less challenged and more confident about understanding the material. These results emphasise the importance of student perceptions of their capabilities when learning in flexible, less structured digital environments.

Using Gamification and Mixed Reality Visualization to Improve Conceptual Understanding in ICT System Analysis and Design
Authors: Muñoz Juan , Cowling Michael , Birt James
Published: May 2024

This paper presents a research design and intervention that investigates how the use of mixed reality visualization and gamification can be applied to an ICT systems analysis and design course. The research focuses on a learning approach of an ICT modelling and design framework based on visual augmentation of traditional course content and class delivery. Assessment of the learning impact in regards to learners, system components and their interaction in system scenarios will be performed. Allowing learners to explore and discover information in the form of a gamified scavenger hunt that supports scaffolding learning chunks, aims to assist them towards a conceptual understanding of the solution. Educators can incorporate selected representations of key learning artefacts and resources in an augmented capacity using a variety of media such as 2d images, videos, graphics, simulations, and 3d models applied into the design process and promote active learning in the classroom.
A review of the literature on flipping the STEM classroom
Authors: Huber Elaine , Werner Ashleigh
Published: May 2024

This study analyses fifty-eight peer reviewed research studies on flipped learning in the higher education STEM disciplines. The review aims to continue on from other meta-analyses and identify themes from the literature, both positive and negative, in terms of perception, engagement and achievement. Two other themes are discussed, the self-efficacy of students and the development of graduate attributes beyond discipline knowledge. The review concludes that there has been a large increase in empirical research on flipped approaches to teaching and learning in the STEM disciplines and the findings are overwhelmingly positive.

Published: May 2024

The new wave of mobile VR and AR are anticipated to become a multi-billion dollar industries in the near future (F. Cook, 2016) ???? how will this impact higher education? This Symposium will gather the collective experience and expertise of members of the newly established Ascilite Mobile Learning Special Interest Group (Ascilitemlsig) to explore and discuss the potential and issues surrounding the rapidly developing fields of mobile Augmented Reality and mobile Virtual Reality. The SIG seeks to draw develop an international community of mobile learning researchers in the context of mobile VR and AR. Building upon the global popularity of the Pokémon Go app, Google Cardboard, and the Samsung Gear VR, there is now widespread interest in these technologies, but still little expertise in integrating these within authentic educational experiences beyond another form of interactive content delivery. Members of the Ascilitemlsig will discuss the potential of mobile AR and VR for user generated content and contexts, share their recent practice-based research, and invite interaction from the wider Ascilite conference attendees.
Designing a toolkit to support the development of copyright literacy
Authors: Van der Veer Beale , Carew Tony , Padgett Luke
Published: May 2024

The Open Education Licensing (OEL) project team surveyed teaching and other staff in the Australian higher education sector. The surveys informed the design of a Toolkit web application, which would provide tailored information to users by presenting relevant questions and guidance in a decision tree format. The decision tree provides pathways to guidance regarding the licensing of teaching resources for Australian higher education. The software was developed iteratively, allowing subject matter experts (SME) to feed in their content whilst the data system and interface were designed and implemented. A user-centred methodology was employed to maximise usability. The Toolkit used open source technologies and is itself openly licensed. This poster communicates the process of design, development and testing of the Toolkit web application. The lessons learned through this process may help inform the design of other innovative systems that aim to emulate the support provided by SME.
Lactate-induced IGF1R protein lactylation promotes proliferation and metabolic reprogramming of lung cancer cells
Authors: Zhang Rong , Li Lulu , Yu Junyan
Published: May 2024

Lung cancer (LC) is regarded as a fatal cancer, and insulin-like growth factor 1 (IGF1) and its receptor (IGF1R) have been found to play a key role in regulating tumor glycolytic metabolism. The aim of this study is to investigate LC proliferation regulated by metabolite-mediated IGF1R lactylation. IGF1R was highly expressed in LC tissues and cells, and the effects of IGF1R on protein stability were inhibited by Lactate dehydrogenase A (LDHA) inhibition. Moreover, the tightness of IGF1R binding to IGF1 was also enhanced by exogenous lactic acid but suppressed by LDHA silencing, while cell viability and proliferation were promoted by over-expression of IGF1R. Exogenous lactic acid further exacerbated the effects of the IGF1R gene, while LDHA knocking down reduced the IGF1R-induced malignant behaviors. The IGF1R and exogenous lactic acid were also found to increase extracellular acidification rate (ECAR) and decrease oxygen consumption rate to regulate glycolysis, which was inhibited by LDHA deficiency in LC cells. The study concluded that IGF1R-mediated aggressive behaviors of LC cells were associated with higher levels of IGF1R lactylation. Moreover, lactic acid can improve the protein stability of the IGF1R oncogene, thus promoting glycolysis and generating lactic acid, forming a closed loop. Therefore, targeting IGF1R is envisaged to provide a novel strategy for developing therapeutic agents against LC.
Role of Embinin in the reabsorption of nucleus pulposus in lumbar disc herniation: Promotion of nucleus pulposus neovascularization and apoptosis of nucleus pulposus cells
Authors: Meng Yingying , Liu Wei , Liu Haifeng , Yu Chengwei
Published: May 2024

Reabsorption of the nucleus pulposus (NP) in lumbar disc herniation (LDH) refers to the natural absorption or even complete disappearance of LDH. In order to better treat LDH, it is necessary to further study its mechanism and develop new therapeutic drugs. Clematidis Radix Et Rhizoma is a ranunculus family plant which has multiple biological activities, and Embinin is one of its bioactive ingredients. However, its effects on LDH were unclear. In this study, the role of Embinin was investigated in LDH rat models. LDH model was established by lumbar epidural insertion of tail disc. Our results showed that Embinin promoted lumbar disc neovascularization, induced apoptosis of NP cells in LDH rats, and promoted lumbar disc resorption. Furthermore, mechanistic study showed that Embinin activated the cAMP pathway in the rat models. In conclusion, Embinin has the potential to serve as a drug for the treatment of LDH.
Novas formas de olhar. Fotografias coloniais em exposições portuguesas na atualidade
Authors: Burgert Anne
Published: May 2024

Este artigo debate o efeito que o uso de fotografias coloniais tem quando são utilizadas em exposições hodiernas. Analisam-se as condições e a perspetiva sob a qual foram tiradas e a exatidão — ou falta dela — das imagens no que toca à representação colonial e do Império português. Analisa-se também qual é o efeito que as fotografias têm quando são hoje apresentadas em exposições diversas. Procura-se mostrar que, com a devida distância temporal e consciência histórica, as fotografias coloniais motivam uma reescrita do conceito de Império.
“A formidavel confusão da natureza”: écfrase e ecopoética na reescrita do Império português no romance O terremoto de Lisboa (1874) de Pinheiro Chagas
Authors: González Danae Gallo
Published: May 2024

Este artigo analisa o romance O terremoto de Lisboa (1874) de Manuel Pinheiro Chagas (1842–1895), uma obra maioritariamente negligenciada pela crítica literária. Após uma revisão do estado da arte e uma justificação da pertinência da minha análise, será feita um close reading ecopoético da écfrase com que o terramoto é representado. Pretende-se examinar a reescrita nesta obra da catástrofe e da crise que o terramoto de 1755 provocou na capital do Império português, pouco depois do primeiro centenário do terremoto de Lisboa e setenta anos após a independência do Brasil (1822).
Computed tomography–guided percutaneous cryoablation of hereditary adrenal pheochromocytoma in three patients
Authors: Griffing Emily , Reading Brenton , De Luca Francesco , Agne Daniel , Juang David , Halpin Kelsee
Published: May 2024

Objectives

Pheochromocytomas (PHEO) are neuroendocrine tumors rarely diagnosed in children. We are reporting on the management challenges of three adolescent patients who present with hereditary PHEO.

Case presentation

The index patient and his male sibling presented with bilateral PHEO, while a third patient presented with a unilateral PHEO, all associated with von Hippel–Lindau (VHL) syndrome. The patients were treated with computed tomography (CT)-guided percutaneous cryoablation (CRA) of the adrenal lesions, with varying degrees of success.

Conclusions

CT-guided percutaneous CRA of hereditary PHEO has not been reported in the pediatric population and may represent a novel treatment strategy that reduces the risk of intraprocedural complications and adrenal insufficiency (AI).

Thermo-mechanical characteristics of spent coffee grounds reinforced bio-composites
Authors: Yanen Cenk
Published: May 2024

This research examines the incorporation of spent coffee grounds (SCGs) into composite materials utilizing a three-part system composed of modified castor oil, polyester resin, and SCGs. The objective is to assess the mechanical, microstructural, and thermal characteristics of the resultant composites. The composite specimens underwent a thorough preparation and were tested through a battery of procedures comprising tensile testing, shore D hardness testing, SEM, FT-IR, and thermal conductivity measurements. Tensile testing revealed higher mechanical resilience, reinforcing the desirable properties of SCGs. The 5 % SCG-reinforced sample exhibited the highest tensile strength value, with a 41.85 % increase observed in comparison to the pure sample. The results of shore D hardness tests demonstrated that there was no significant change in material hardness up to 3 % additive content. However, a decrease in hardness was observed at higher additive rates. At a 7 % additive rate, there was a 2.82 % decrease in material hardness. Furthermore, the application of scanning electron microscopy (SEM) analysis has revealed the microstructural features of the composite matrix, which have highlighted the distribution of SCGs within it. The successful implementation of SCGs has also been verified by means of Fourier transform infrared (FT-IR) analysis. Finally, based on thermal conductivity measurements, it has been determined that SCGs are suitable for thermal insulation purposes. This study represents a significant contribution to the field of sustainable materials science, emphasising the potential benefits of SCGs in improving the effectiveness of composite materials.
In situ synthesis of reduced graphene oxide/SnIn4S8 nanocomposites with enhanced photocatalytic performance for pollutant degradation
Authors: Wang Zhonghui , Gao Qiang , Luo Haihang , Fan Haojun , Chen Yi , Xiang Jun
Published: May 2024

A type of reduced graphene oxide (rGO)/SnIn4S8 (SIS) nanocomposites was successfully fabricated by a facile and efficient microwave-assisted method. Their morphology, structure, composition, and optical performance were investigated by different analytical techniques, respectively. The results indicated that rGO had an important effect on the structure of photocatalysts. As the content of rGO increases, the unchin-like microsphere structure of rGO/SIS evolved gradually into aggregated nanosheet structure. The photocatalytic degradation experiments were carried out under visible light irradiation. The results demonstrated rGO/SIS-2 nanocomposites exhibited higher photocatalytic activity toward the degradation of RhodamineB than that of SIS, rGO/SIS-1 as well as rGO/SIS-3. Meanwhile, the mineralization efficiency of Rhodamine B (RhB) can reach up to 73.8% within 30 min. Interestingly, rGO/SIS-2 nanocomposites exhibited excellent recycle stability with 96% removal efficiency of RhB after three cycles. The enhanced photocatalytic activity of rGO/SIS-2 nanocomposites should be attributed to the strong interaction of rGO and SIS, the decrease of band gap energy, the enhanced visible light absorption, and excellent electrons’ mobility of rGO, thereby promoting charge separation. Finally, the mechanism of rGO/SIS nanocomposites for the degradation of RhB has been also proposed. This work provides a facile and efficient pathway to prepare SIS-based nanocomposites with enhanced catalytic efficiency by combining the advantages of microwave-assisted heating and incorporating carbon-based nanomaterials for the degradation of organic pollutants in visible light irradiation.
Mucocutaneous Manifestations Reported by Inflammatory Bowel Disease Patients in University Hospital
Authors: Jonaitytė Ieva Renata , Karpavičiūtė Vita , Kiudelis Gediminas , Kupčinskas Juozas , Jonaitis Laimas
Published: May 2024

Background: Inflammatory bowel disease (IBD)` may affect organs outside the intestines, it is called extraintestinal manifestations of IBD. Data on the prevalence of mu-cocutaneous manifestations in IBD patients are very limited, therefore, the aim of this study was to assess the prevalence of skin and mucosal lesions and to determine the relationship with demographic factors, clinical features, and systemic treatment.Materials and methods: Prospective study included 162 out-patients with IBD who were managed in the tertiary care center. Ulcerative colitis (UC) was diagnosed in 117 patients, Crohn‘s disease (CD) in 45. Patients completed the questionnaire containing demographic and IBD data, questions about mucocutaneous lesions (in past or present state).Results: Overall mucocutaneous lesions were reported by 48.1% of IBD patients. Skin lesions were reported by 40.7% of patients, oral mucosal lesions were reported by 16.7%, without significant differences between sexes or IBD types. In 47 (29%) of patients, skin lesions appeared together with IBD or during the course of the disease. The most common skin lesions were psoriasis (8.0%), erythema nodosum (5.6%), pyoderma gangrenosum and acne (3.7% each). UC patients mostly reported about psoriasis (9.4%), while CD patients about erythema nodosum (11.1%). There were more frequent skin lesions in patients with more extensive UC type (p = 0.01), while no difference was noticed between different types of CD. The average duration of IBD in patients with skin lesions was similar to those without lesions (9.3±6.7 vs. 9.4±6.7 years).Conclusions: Mucocutaneous lesions were reported by 48.1% of inflammatory bowel disease patients. The frequency of mucocutaneous lesions does not differ significantly between UC and CD, and a longer duration of illness is not a predictive factor for the appearance of lesions. More extensive UC is related to higher frequency of skin lesions.

Advancing a Holistic Framework for Classifying SAI Performance Audit Impact Factors: Integrated Scientific Assumptions
Authors: Šaliene Asta
Published: May 2024

The article raises the problem of the need to reconceptualize the framework of the impact factors of the performance audit performed by Supreme Audit Institutions (SAI). The research aims to identify performance audit impact factors and propose an expanded, comprehensive framework. To implement the aim, the integrative method of scientific literature analysis is employed. Throughout the study, a systematic exploration of scientific literature is conducted to identify and organize hypothetical and previously researched impact factors discussed by scholars. The identified factors are aggregated according to their characteristics, meaning, or nature, and are divided into ten pillars: accountability, context, legitimacy, political overtones, quality of the performance audit, social relations, stakeholders, logic of public administration, the multifunctional activity of performance audit, and the individual. The broader framework of performance audit impact factors created will be beneficial for further research into managing these factors, enhancing evaluation opportunities, enabling performance auditors to mitigate associated risks, and capitalizing on the positive properties of these factors.
Recent trends of diabetes and phase angle (PhA) by bioelectrical impedance analysis (BIA)
Authors: Bando Hiroshi
Published: May 2024

Recent topics regarding diabetes and Phase Angle (PhA) by the Bioelectrical Impedance Analysis (BIA) method were introduced. Decreased PhA value means impaired cell function of human body. PhA was significantly lower in Type 2 diabetes (T2D). T2D cases of 30-83 years showed average data of PhA 6.84/5.99, and HbA1c 7.35/5.95% as male/female. When male cases were analyzed for lowest quartile with the data of PhA ≤4.9, they showed odds ratio (OR) 2.02 with significantly higher prevalence of diabetes. Regarding diabetic polyneuropathy (DPN), PhA value showed control 6.18, T2D without DPN 6.07 and T2D with DPN 5.71 with significant difference.

Hydrophilic polymer/inorganic hybrids (PIH) containing silica nanoparticles and polyacrylamide chains proved to be effective matrices for the in situ synthesis of cobalt nanoparticles. PIH sample was synthesized by free-radical polymerization of acrylamide from the unmodified surface of SiO2 nanoparticles and characterized by elemental analysis, dynamic thermogravimetric analysis, static light scattering, potentiometric titration, viscometry and transmission electron microscopy (TEM). The processes of borohydride reduction of cobalt ions from the Co(NO3)2·6H2O solution to nanoparticles in water medium and aqueous solutions of PIH were studied as a function of the concentrations of metal salt and hybrid concentrations using UV-Vis spectroscopy and TEM. A special approach to characterize the kinetics and efficiency of CoNPs formation in water medium and hybrid solutions using UV-Vis spectroscopy was implemented. The kinetic parameters of the CoNPs formation process as well as the yield, size, and morphology of nanoparticles in hybrid solutions and water medium at various concentrations of metal salt and hybrid were determined. The growth of both concentrations of reagents had a positive effect on the rate of formation of metal nanoparticles and their yield, but in all cases, the reduction process developed much slower in hybrid solutions compared to pure water. The morphology of the CoNPs/PIH nanocomposites was mainly represented by separate swollen hybrid particles containing metal nanoparticles with dav~3 nm.

The series of organic-inorganic hybrid nanocomposites based on branched polyimide matrix and with different amounts of tetraethoxysilane (TEOS) (5, 20, and 50 wt.% of the initial polyamic acid mass) were synthesized and studied using nitroxyl paramagnetic probe, measuring dielectric permittivity, X-ray structural analysis and optical microscopy. It was shown that in some cases the introduction of inorganic component is accompanied by a decrease in the segmental mobility of polyimide matrix as a result of the partial immobilization of organic macrochains during the formation of inorganic microregions. In the presence of inorganic component, a weak dependence of the polymer permeability on the content of the organic component in the system is observed, also the specific density changes little with an increase in TEOS content. Extreme changes in the segmental mobility and dielectric permittivity of the branched matrix formed in the presence of 5 wt% TEOS were found compared to systems of other compositions. This can be caused to a large extent by structural changes in the system. At a low content of TEOS occurs significant «loosening» of organic matrix, a sharp decrease in the dielectric constant and a significant increase in the segmental mobility of the polyimide matrix. Small angle X-ray scattering diffractograms demonstrate drastic changes in polyimide composite heterogeneity in the presence of 5 wt.% TEOS content. According to the optical microscopy data, the introduction of TEOS into polyimide is accompanied by the formation of microaggregates of inorganic nanoparticles in the system, the number and average size of which depend on the SiO2 content and looks most homogeneous at a low TEOS content.

Interpenetrating polymer networks based on biocompatible components – polyurethane and copolymer of 2-hydroxyethyl methacrylate with methacryloyloxyethylyphosphorylcholine (HEMA-MPC) were synthesized and thermodynamic parameters of interactions in the system and morphology were investigated. The thermodynamic parameters of interactions between polymer components of the IPNs were calculated based on sorption isotherms of methylene chloride vapors by samples of the created polymer systems. It is shown that MPC plays the role of a compatibilizer in the system, increasing the thermodynamic compatibility between polyurethane and the HEMA-MPC copolymer at small amounts of the copolymer in the IPNs. As the amount of copolymer HEMA-MPC in the IPNs increases, the value of the free energy of the polyurethane and copolymer mixing shifts to the positive value, which is associated with the formation of ionic clusters of MPC. This may mean that with an increasing amount of the MPC in the system, interactions between the negatively charged phosphoryl groups and the positively charged nitrogen atom of various MPC polymer chains occur, i.e., the part of intermolecular interactions (polyurethane and copolymer) decreases, while the part of intramolecular interactions (between different groups of MPC) increases. The results of the morphology investigations of the IPN samples are consistent with the data of the thermodynamic compatibility study of polymers during the formation of the IPNs. With a significant increase in the positive values of the free energy of the polyurethane and copolymer mixing in the IPNs with 41 % and 51 % of the copolymer content, a significant phase separation is observed in the IPNs, with phase inclusions ranging from 1 to 5 mm.

Background: This research addresses the dearth of Human Resources studies within the logistics sector, offering valuable insights into the intricate relationship between resonant leadership and employee attitudes. With a focus on trade logistics firms in Delhi and the National Capital Region of India, the study seeks to fill a void in the existing literature by exploring the impact of resonant leadership on organizational commitment and turnover intention. Purpose: The primary objective of this research is to investigate the influence of resonant leadership on dimensions of organizational commitment and turnover intention among employees. Drawing on Social Exchange Theory (SET) and Meyer and Allen’s Three-Component Model of Organizational Commitment, the study introduces organizational commitment as a mediating variable in the resonant leadership-turnover intention relationship. Methods: Conducted through surveying employees in trade logistics firms, the study employed a sample of 371 participants. The data analysis utilized SMART-PLS structural equation modelling to comprehensively examine the relationships between resonant leadership, organizational commitment, and turnover intention. Results: The findings reveal a positive correlation between resonant leadership and organizational commitment, showcasing a significant reduction in turnover intention. Affective commitment emerged as the sole mediating factor in this relationship, highlighting its pivotal role in mitigating turnover intention among employees. Conclusions: This research contributes to the limited literature on the interplay between resonant leadership and employee attitudes, specifically within the context of trade logistics. The study underscores the importance of understanding and managing emotions in the workplace, particularly among leaders, as a means to foster commitment. Ultimately, this commitment acts as a powerful deterrent to turnover, promoting organizational sustainability in the long run.

Design of the intensification method with the help of FracCADE software
Authors: Rubel Victoriia , Pshyk Vadym
Published: May 2024

The object of research in the work is the FracCADE software, with which it is possible to simulate the process of hydraulic fracturing and well field, on which the intensification method is designed. This hydraulic fracturing simulator was developed by Schlumberger Ltd. based on proven physical principles of hydraulic fracturing to optimize the treatment process and proven in practice. The system includes a range of hydraulic fracturing models, from 2D models to extensive 3D simulations with lateral communication. It includes a number of complementary modules for fracturing fluid and proppant optimization, injection scheduling, real-time monitoring, pressure equalization, production forecasting and economic evaluation. Some models allow simulating the geometry of the fracture, solving proppant concentration problems, and simulating possible shielding due to proppant covering the fracture or the dehydration process.
Hydraulic fracturing remains one of the main engineering tools for increasing the productivity of wells. The effect is achieved due to:
– creation of a conductive channel (fracture) through the damaged (contaminated) zone around the well, in order to penetrate beyond its boundaries;
– spreading of the channel (fracture) in the formation to a considerable depth in order to further increase the productivity of the well;
– creation of a channel (fracture), which would allow changing, influencing the fluid flow in the formation.
In the latter case, fracturing really becomes an effective tool that allows to manage the operation of the reservoir (in particular, change its filtering characteristics) and implement long-term strategic development programs. The concept of hydraulic fracturing is quite simple. In general, for relatively simple geology, the physical foundations of fracturing theory are fairly well developed and tested. For the most part, the difficulties boil down to two problems: the real geological conditions and the complex multidisciplinary nature of the fracturing process itself.
The process of designing fracturing in order to achieve a certain result is closely related to rock mechanics (which affects the geometric parameters of the fracture), fluid hydromechanics (in which the tasks of controlling the flow of the working fluid and placing the proppant in the fracture are solved) and chemistry, which determines the behavior of materials, which are used during hydraulic fracturing. Moreover, the hydraulic fracturing project must take into account the physical limitations imposed by the specifics of the real deposit and well. In addition, to achieve the desired results, the fracturing operation must be carried out in strict accordance with the calculations (that is, a complete cycle in which each operation plays its role).
