Energy Consumption-Economic Complexity Relationship: an Application on EU Countries and Türkiye
Authors: Kartal Mustafa
Published: June 2024

Objective: This study aims to estimate the relationship between energy consumption and economic complexity in 25 European Union member states and Türkiye from 1995 to 2020.
 
Theoretical Framework: The causality relationship between these concepts can be discussed in terms of four theorems (neutrality hypothesis, growth hypothesis, conservation hypothesis, and feedback hypothesis). The lack of a causal relationship between economic complexity and energy consumption is explained by the neutrality hypothesis. The growth hypothesis points to a unidirectional correlation from energy consumption to economic complexity. In the contrary case, a unidirectional causality from economic complexity to energy consumption is the subject of the conservative hypothesis. Finally, the feedback hypothesis reveals the existence of a two-way causal relationship between economic complexity and energy consumption (Gorus ve Aydin, 2019: 816; Dogan: 2015: 535; Liu vd., 2021: 3).
 
Method: First, different approaches explaining the relationship between economic complexity and energy consumption in the relevant literature were examined to create the empirical analysis framework. After the specification of the appropriate model, pooled ordinary least square model, fixed effects model and random effects model were used to estimate the relationship between energy consumption and economic complexity within the country sample. The study investigated the relationship between fossil energy consumption and economic complexity using Emirmahmutoğlu & Köse (2011) panel Granger causality test.
 
Results and Discussion: According to the analysis results, the growth hypothesis appears valid for EU Member States and Türkiye.
 
Research Implications: This result reveals that fossil energy consumption plays an important role in increasing economic complexity, energy conservation policies negatively impact economic complexity, and countries in this situation are highly dependent on energy.
 
Originality/Value: The empirical literature on the relationship between energy consumption and economic complexity is limited. In this study, where the subject of the research is discussed from an empirical perspective, the fact that 25 member countries of the European Union and Turkey were selected as samples increases the originality value of our study.

Venous thromboembolism in two adolescents with Down syndrome
Authors: Kurokami Tsunehiko , Takasawa Reiko , Takeda Sayaka , Kurobe Masashi , Takasawa Kei , Nishioka Masato , Shimohira Masayuki
Published: June 2024

Although venous thromboembolic events are relatively rare in children, they are an increasingly recognized clinical entity in pediatric tertiary care hospitals. Although vascular disorders are prevalent with Down syndrome, it remains unclear whether Down syndrome patients are at higher risk for venous thromboembolic events. We report two adolescent cases with Down syndrome who unexpectedly developed venous thromboembolism in a general care unit. Our cases had a few risk factors; laparoscopic radical surgery for Hirschsprung's disease with central venous catheterisation in Case 1, and bacterial hepatic abscess in Case 2. Despite preventive heparinization with catheterisation and minor surgery in Case 1 and non-sepsis in Case 2, bed rest for only a few days triggered sudden onset of deep vein thrombosis in lower limbs with pulmonary thromboembolism in both cases. We speculate that the characteristics of Down syndrome, including physical and behavioural problems, might cause venous thromboembolic events. Thus, we should pay more attention to the relationship specifically between venous thromboembolism and Down syndrome, especially in adolescents, and increase prevention, early detection and treatment efforts.
The Influence of High Pressure and Temperature on Transport Properties of Liquid Magnesium Oxide
Authors: Thi Lan Mai , Tri Dung Pham
Published: June 2024

This work provides insights into the effects of both temperature and pressure on structure, dynamics, and diffusion mechanism  in liquid magnesium oxide (MgO) systems. The Molecular Dynamics simulation (MDs) method and a kinetic approach are employed in this research. The structure of liquid MgO undergoes changes under compression, primarily consisting of the polyhedral units of MgO3, MgO4, and MgO5 at ambient pressure and MgO5 and MgO6 at high pressures up to 25 GPa. Meanwhile, the structure of liquid MgO is still composed of the polyhedral units of MgO3, MgO4, and MgO5 at different temperatures. The diffusion mechanism in liquid MgO involves the transition of the polyhedral units from MgOx to MgOx±1. We found that two factors contribute significantly to the diffusion process of the liquid MgO system including the mean square of transition dtr and the rate of transition rtr coefficient.

Authors: Van Thang Nguyen , Hoang Oanh Nguyen , Huy Kien Bui , Duc Luong Vu , Duc Hung Pham
Published: June 2024

The aim of this work is to establish the bulk modulus expressions of fullerene C60 in both linear and nonlinear deformation cases. The Lennard-Jones potential energy is used to calculate the bonding forces between carbon atoms. The research results reveal a formula demonstrating the dependence of the bulk modulus on the volume of the fullerene in the case of significant volume deformation (nonlinear case). Consequently, the bulk modulus of fullerene C60 can be determined basing on the volume deformation ratio. A comparison between the bulk modulus in general case (large deformation - nonlinear) and specific case (small deformation - linear) has been made. The results obtained through the Finite Element Method (FEM) and Density function theory (DFT) have affirmed the accuracy of the research results.
Comparing the Luminescence and Moisture Resistance of K3AlF6:Mn4+ Phosphor to Commercial Phosphors
Authors: Kim Lien Nguyen Thi , Duy Hung Nguyen
Published: June 2024

Nowadays, red-emitting phosphors based on Mn4+ doped fluorides with a high color purity and a relatively short decay time can improve the optical performance of WLED. However, they are easily oxidized in humid environment and elevated temperatures. This is the reason why both the brightness and luminous efficiency of WLED quikly decreased. To solve this problem, KF was added throughout the K3AlF6:Mn4+ phosphor synthesis process (KKAFM). This work is focused on aging evaluation of the phosphors and comparing its performance with commercial phosphors (YAG:Ce3+, Sr2Si5N8:Eu2+). Thus, EL spectra of blue LED chips coated with the phosphors were investigated over time in an environment of 85 % RH and 85 oC. The results of EL spectra showed the improvement in the the reduction of the emission intensity of KKAFM. Aging tests of WLEDs using KKAFM and Sr2Si5N8:Eu2+ indicated that KKAFM phosphors exhibited a good stability, thus they can be used as a potential replacement for commercial red-emitting phosphors in WLEDs fabrication.
The Social Responsibility of Women During the New Order
Authors: Amini Mutiah
Published: June 2024

This paper discusses the lives of Indonesian women within the confines of family and community amidst the strengthening of programs pertaining to women’s empowerment that were launched by the New Order administration from 1966 to 1998. The significant questions this research addresses are: 1) How was the empowerment programs conducted? and 2) How did the programs affect the lives of women within their families and communities. The results of this study showed that during the New Order administration, it became apparent that women lost their autonomy as burdens were stacked on them within their families and communities. Through empowerment programs, women were expected to be robust and independent; however, because the New Order programs were structurally designed to be heavily centralized, they instead reinforced the existing traditional social construction. As the women subsequently bore heavy burdens to thrive accomplishment in both familial and communal spheres, the introduced programs worked instead to repressively narrow women’s chances for autonomy. This historical research study utilized a variety of data in the forms of documents, both archival or memoir types.
The Relation of Various Durations of Type II Diabetes Mellitus and Endothelial Dysfunction
Authors: Alhameed Mohammed Ali , Jaccob Ausama Ayob , Alidrisi Haider A.
Published: June 2024

Background: Patients with long-term diabetes have a higher prevalence of endothelial dysfunction. Hypercholesterolemia strongly associates this impairment with atherosclerosis, while the duration of diabetes may relate to early macrovascular and microvascular injury.
Objectives: The present study assessed the possible relation between various durations of type II diabetes and endothelial dysfunction.
Methods: A case-control study of 182 participants included 20 healthy subjects, 30 newly diagnosed diabetes patients, and 132 with varying diabetes durations of type II diabetes. Those patients were divided according to their duration: 50 patients were (1-5 years), 32 patients were (5-10 years), and 50 patients were (more than ten years) in addition to the newly diagnosed group and the healthy control group. Lipid profile, glycemic parameters, and endothelium biomarkers: oxidized nitric oxide (NO), endoglin, intercellular adhesion molecule (ICAM-1), and glutathione were measured. Data was collected from November 20, 2022, to March 31, 2023.
Results: Body mass index was significantly elevated in diabetic groups compared to the normal control group. All diabetic groups had highly significant differences in lipid profile and glycemic control parameters compared to the control group. Patients with more than ten years of diabetes had significantly higher (NO) levels than other groups, while the ICAM-1 level in these patients was significantly higher than all other groups.
Conclusions: Various duration of type II diabetes was related to endothelial dysfunction that was strongly linked with factors like body mass index, systolic hypertension, hyperlipidemia, and poor control of glycemic index.
Numerical Investigation of Gas Models for Retropropulsion Flows for Future Mars Missions
Authors: Nastac Gabriel , Frendi Abdelkader
Published: June 2024

Supersonic retropropulsion is a key technology for next-generation rockets and necessary to land large payloads for human-scale missions. The recent decade has demonstrated the capability to land rockets on Earth as well as the reuse of said rockets to reduce cost. This capability thus far has relied on flight tests. For future missions to Mars, testing requires many compromises, as flight tests are not possible on Earth. Computational fluid dynamics (CFD) simulations are critical to the design and analysis of extraplanetary retropropulsion configurations. This work investigates a single-engine configuration that was previously tested in a wind tunnel using an air medium. The configuration is scaled to Martian conditions. Various gas modeling approaches are employed, including pure [Formula: see text], pseudo-species, and a chemical mechanism to model the afterburning of the engine plumes in the Martian atmosphere. The scale-resolving CFD simulations are compared to the simulation and experimental data of the air configuration. The lower-fidelity gas modeling simulations are also compared against the higher-fidelity chemical mechanism simulations to examine the impact of gas models on plume flowfields and forces and moments that are of interest to vehicle design.
Effect of Adhesive Layer Thickness on Strength of Carbon-Fiber-Reinforced Plastic/Aluminum Bond-Riveted Joints
Authors: Guo Chengxiang , Zhang Minghao , Huo Lubin , Cao Zengqaing
Published: June 2024

This paper investigated the mechanical performance, progressive failure process, and failure modes of riveted joints, bonded joints, and hybrid joints with different adhesive layer thicknesses connecting carbon-fiber-reinforced plastic (CFRP) and aluminum alloy subjected to quasi-static tensile loading. The 2D digital image correlation technique was used to record the deformation and strain of the overlap area. The results show that the thickness of the adhesive layer had a negative effect on the mechanical properties of the hybrid joints, and when the thickness of the adhesive layer was increased from 0.2 to 0.8 mm, the peak load and the energy absorption (EA) values of the hybrid joints were reduced by 14.38 and 23.22%, respectively. Compared with the bonded and riveted joints, hybrid joints showed better performances in peak load and EA values, and rivets were able to continue carrying loads when the adhesive layer failed. The typical failure modes of the hybrid joints included CFRP compressive failure, adhesive failure, fiber-tear failure, and light-fiber-tear failure. It was further found that the adhesive could disperse the stress around the rivet holes and effectively reduce the stress concentration around the rivet holes.
EXISTE UM NOVO FEDERALISMO NA ARGENTINA? PARA UM FEDERALISMO DE COOPERAÇÃO
Authors: Colombo Murúa Ignacio
Published: June 2024

Será proposto que a recente jurisprudência da Suprema Corte da Justiça da Argentina (CSJN) tem reconhecido uma nova dinâmica no federalismo argentino. Isso, segundo se sustenta, ficou claro com o reconhecimento crescente de faculdades ou competências concorrentes em relação aos sujeitos federados. Isso implica o abandono de uma visão rígida do sistema, como se tratasse de sujeitos separados, com finalidades distintas e, portanto, com competências rigorosamente atribuídas; passando a uma visão flexível e de integração na relação dos sujeitos federados. A hipótese de trabalho será a seguinte: o federalismo argentino nasceu como a única maneira de alcançar a unidade nacional, mas, por essa mesma razão, impregnou as instituições com uma forte hermenêutica centralizada. A ideia era que, para alcançar a unidade, era necessário fortalecer a posição do governo federal. Nesse contexto, a atribuição de competências era de "tudo ou nada" - o federalismo "dual" era o mais adequado para esse fim - e a balança pendia quase sempre a favor do governo central. Após essa origem pragmática, o federalismo, junto com a unidade nacional, se estabeleceu como um sistema quase indiscutível em nosso país, surgindo assim a necessidade de repensá-lo. No entanto, nesse caminho, o centralismo no reconhecimento de competências não foi desarticulado, mas, competindo com ele, surgiu uma reatribuição de competências, agora concorrentes e compartilhadas, sob responsabilidade das províncias. Do federalismo "dual", está-se passando para um federalismo "cooperativo", de "concertação" ou "relacional"; onde as decisões são tomadas de maneira articulada e coordenada entre o central e o local, e onde a ideia de sujeitos em competição é substituída por uma de sujeitos integrados.

Published: June 2024

The purpose of this study was to invite five elementary teachers to reflect on
how established elementary English education is and to identify needed changes
toward a well-perched elementary English education. The views of five teachers
were collected through interviews and analyzed through thematic analysis.
Previous studies in support of their views are presented, and they attest that
these views are shared among teachers and researchers on a larger scale. The
results of the study suggest that elementary English education fulfill its
responsibility to ensure learners basic academic level proficiency, that the current
practice of the specialist-teacher-based teaching system be replaced with the class
teacher system, that sturdy phonics program be included in the national
elementary English curriculum, and that means be taken in order for effective
teaching know-hows and practices to be introduced and shared among teachers.
The study reports on recent positive national level actions toward assisting
learners securing basic academic proficiency and providing more ground in
teaching phonics.
Elementary teacher’s narrated experiences of the English Test for Elementary Teacher Certification Examination.
Authors:   The Korea Association Of Primary English Education, Kim Geun-Ho
Published: June 2024

This study aimed to explore the elementary teachers’ perceptions about preparing and
taking the English Test for Elementary Teacher Certification Examination. This study
also collected ideas from teachers for improving the test. To achieve the purpose of
the study, 10 interviewees were selected. Their narrated experience of the test
preparation and test taking was recorded in the form of in-depth interviews. The
recorded data was analyzed according to the six-step processes of interpretive
phenomenological analysis (IPA) proposed by Smith et al(2009). The analysis led to
the following findings: First, the 1st English test and preparation process was effective
in some respects for those who had taken it, helping them to teach English and other
subjects. However, the majority of interviewees also reported that the test preparation
process was physically and mentally demanding. Because they could not obtain
information easily, they had to purchase an internet lecture to prepare for the exam.
Second, the 2nd test (English In-depth Interview, English demonstration lesson) and
preparation process are designed to help teacher candidates prepare to teach English.
However, when reflecting on their own elementary school fieldwork experience, some
respondents felt that there was less of a connection between the fieldwork and the
English demo-lesson in the test. In conclusion, the experience is meaningful to teachers,
however there are gaps between the test and the fieldwork. So, we have to consider
how to renovate the exam for a more reasonable teacher recruitment and training.

Like any other Western country, Turkiye is becoming an educational destination for many international students, especially Africans. Therefore, Turkiye emphasizes universities' internationalization, which brought rapid success to its political and economic trends. Therefore, this present study investigated the plights of West African students in Turkish universities, specifically focusing on the West African students at Gaziantep University. The study is based on a qualitative research design with a case study approach. This study used interviews and observation to collect data from 12 participants—one participant at least from each of the 10 West African countries presently active at Gaziantep University. The data collected were qualitatively analyzed based on common themes designed for this study. According to the findings of this current study, the language and prejudice of locals against West African students and the country they come from where the enormous challenges they faced while at Gaziantep University. Concerning these findings, the present study recommends addressing the problems mentioned earlier, such as special orientation programs organized by the university and other relevant bodies, which should be delivered by university staff familiar with Africans' socio-cultural heritage and economic and political background. Likewise, scholarships and financial support from the government and other relevant authorities should be given to West African students to overcome the financial problems they encountered during their stay at Gaziantep University

Edukacja plastyczna kobiet od starożytności po epokę nowożytną na przykładzie wybranych artystek. Pomiędzy sukcesem a dyskryminacją
Authors: Sprutta Justyna
Published: June 2024

Artykuł stanowi próbę przyjrzenia się losom wybranych, kształcących się w sztuce dziewcząt i kobiet od starożytności po epokę nowożytną. Często dyskryminowane, zmagające się ze stereotypami, odnosiły sukcesy jako artystki. W refleksji zaprezentowane zostaną możliwości, jakimi cieszyły się owe dziewczęta i kobiety, skala ich osiągnięć, ale też przeszkody wyłaniające się zazwyczaj z ówczesnej mentalności, uniemożliwiające im naukę na „wyższym poziomie”. Artykuł jest szkicem zagadnienia, poniekąd wstępem do badań nad zawartym w tytule problemem, gdyż przynajmniej na rodzimym gruncie nie poczyniono głębokiej refleksji nad zagadnieniem artystycznego kształcenia dziewcząt i kobiet w nowożytności przez pryzmat na przykład ich dyskryminacji. Artykuł z pewnością nie wyczerpuje tematu, lecz stanowi jedynie zachętę do gruntownego i szerokiego zajęcia się zagadnieniem, jakim jest wspomniana edukacja i to nie tylko w podanych ramach czasowych.

Autor kładzie szczególny nacisk na przedstawienie prawidłowości rządzących tym, co wpływa na zmianę statusu preceptora. Wskazano różne przyczyny konieczności reinterpretacji misji współczesnego pedagoga, łącząc ten fakt z wybranymi odniesieniami do sytuacji z życia oświaty. Tekst zawiera ponadto możliwie szeroką wykładnię powodów, dla których zmiana światopoglądu społecznego pod wpływem procesów kulturowych i obyczajowych wręcz wymusza nadanie nowej rangi funkcji nauczyciela. Artykuł wskazuje na potrzebę dostrzeżenia szerszego kontekstu, w jakim odbywa się kształtowanie nowego wizerunku preceptora i jego powinności. Tekst sygnalizuje w wyrazisty sposób układ relacji panujących w środowisku szkolnym z perspektywy nauczycieli, uczniów i rodziców względem oczekiwań wobec nauczyciela. Opracowanie ma być formą aktualizacji pewnych zagadnień związanych ze społecznym postrzeganiem nauczyciela i kwestią sprecyzowania nowej wizji preceptora w świetle dokonujących się przemian w dziedzinie kultury, nauki, wychowania i stosunku do wartości w aspekcie etycznym.

Published: June 2024

В условиях глобализации и стремительных трансформаций мирового порядка проблематика патриотического образования приобретает особую актуальность. Настоящее исследование посвящено комплексному анализу современного состояния, ключевых проблем и перспектив развития патриотического образования в контексте глобализационных процессов. Методологическую основу работы составили системный подход, компаративный анализ, социологические опросы и статистические методы. В ходе исследования выявлено, что в 78% стран мира патриотическое образование включено в государственные образовательные стандарты, однако его эффективность варьируется в зависимости от региона: от 62% в странах Европы до 91% в государствах Азии. Установлено, что ключевыми проблемами являются: недостаточная адаптация патриотического образования к вызовам глобализации (отмечена в 69% исследований), разрыв между теорией и практикой (75%), низкий уровень вовлеченности молодежи (64%). Анализ перспективных направлений развития показал, что наибольший потенциал имеют: интеграция патриотического образования с глобальным образованием (прогнозируемый рост эффективности на 27%), широкое внедрение интерактивных и проектных методик (до 32%), усиление роли институтов гражданского общества (до 19%). Полученные результаты могут быть использованы для модернизации систем патриотического образования и разработки стратегий его развития как на национальном, так и на глобальном уровнях.

In the context of globalization and rapid transformations of the world order, the problems of patriotic education are becoming particularly relevant. The present study is devoted to a comprehensive analysis of the current state, key problems and prospects for the development of patriotic education in the context of globalization processes. The methodological basis of the work was a systematic approach, comparative analysis, sociological surveys and statistical methods. The study revealed that in 78% of the world's countries patriotic education is included in state educational standards, but its effectiveness varies depending on the region: from 62% in European countries to 91% in Asian countries. It was found that the key problems are: insufficient adaptation of patriotic education to the challenges of globalization (noted in 69% of studies), the gap between theory and practice (75%), low level of youth involvement (64%). The analysis of promising areas of development has shown that the greatest potential is the integration of patriotic education with global education (projected increase in efficiency by 27%), widespread introduction of interactive and project-based methods (up to 32%), strengthening the role of civil society institutions (up to 19%). The results obtained can be used to modernize patriotic education systems and develop strategies for its development both at the national and global levels.
Mechanisms Underpinning Heterogeneous Deconstruction of Circular Polymers: Insight from Magnetic Resonance Methodologies

Published: June 2024

Circular plastics thrive on the ability to chemically recycle polymers into reusable monomers, ideally closing the loop from manufacturing to end of life. Mechanisms for heterogeneous polymer deconstruction are complex, involving diffusion and transport of reagents to reactive sites in a material continuously undergoing chemical transformations. A deeper understanding of deconstruction phenomena would better inform the molecular basis of circularity in plastics. Here, we show how nuclear magnetic resonance (NMR) spectroscopy, relaxometry, and diffusometry enable monitoring of heterogeneous deconstruction of a model elastomer with acid-cleavable diketoenamine bonds. In chaotropic aqueous HBr, polydiketoenamine (PDK) deconstruction is fast, enabled by macro- and micro-scale swelling in early stages, which facilitates acid penetration and protonation of reaction sites deep within the polymer sample. We observe a previously unrecognized hydrogen-bond stabilized protonated amine intermediate that is persistent throughout deconstruction, and found a strong correlation of its reactivity with swelling and chain kinetics. In kosmotropic aqueous H2SO4, PDK deconstruction is notably slower. Swelling occurred at a more gradual pace, creating a porous polymer matrix, yet polymer chain mobility remained low. Most notably, the kosmotropic character of aqueous H2SO4 resulted in a reaction site that was comparably less active in advancing hydrolysis and deconstruction to shorter oligomer chains, instead trapping acid in matrix pores and modifying the activity of the reaction medium under confinement in the process.
2D-IR spectroscopy of azide-labeled carbohydrates in H2O
Authors: Gasse Philip , Stensitzki Till , Müller-Werkmeister Henrike M.
Published: June 2024

Carbohydrates constitute one of the key classes of biomacromolecules, yet vibrational spectroscopic studies involving carbohydrates remain scarce as spectra are highly congested and lack significant marker vibrations. Recently, we introduced and characterized a thiocyanate-labeled glucose1 demonstrating the use of vibrational reporter groups for 2D-IR spectroscopy of carbohydrates. Here, we expand upon those results and elucidate the performance of azide groups as vibrational reporter for carbohydrates. Originating from applications in click-chemistry, different azide-labeled carbohydrates are readily available. We have characterized azide-labeled glucose, galactose, acetylglucosamine and lactose in water using IR and 2D-IR spectroscopy. Our findings indicate that their absorption profiles are primarily determined by the labeling position on the ring. However, we also observe additional variations between samples with the same labeling position. Furthermore, we demonstrate that their usage remains feasible at biologically relevant concentrations.

Published: June 2024

For decades, the synthesis of 2-quinolones, a crucial structural motif in pharmaceuticals and agrochemicals, has relied heavily on costly noble metal complexes and structurally complex ligands. Despite considerable efforts from synthetic chemists, a mild, metal-free, environmentally friendly, and cost-effective approach has remained elusive. This study introduces a robust, metal-free synthetic platform that leverages an innovative organoiodine-catalyzed electrophilic arene C(sp2)-H amination strategy to efficiently produce a wide range of new and modifiable 2-quinolones. Moreover, this study allows ready synthetic access to novel 8-aryl-substituted 2-quinolones, uncovering new chemical spaces with significant potential for medicinal applications.

Lithium-ion battery recycling offers an opportunity to develop innovative technologies to close the loop on the battery materials cycle and increase the resilience of the battery supply chain. Here we demonstrate a two-step pyroelectrochemical method for producing mixed-metals from lithium-ion cathodes in a molten hydroxide salt. Mixed metal oxides in the form of insoluble lithium-ion cathode materials of LiNi0.6Mn0.2Co0.2O2 and spent lithium-ion battery materials (black mass) were electrochemically reduced to a soluble form and dissolved into a molten hydroxide salt bath. Electrochemical characterization of the process salt indicated accumulation of dissolved transition metals in the salt. A separate cathode was used to produce alloys of Ni, Mn, and Co electrochemically from the dissolved lithium-ion cathode materials. Characterization by scanning electron microscopy fitted with an energy dispersive X-ray spectrometer showed transition metals present in the cathode materials were recovered at the separate cathode. This approach represents a scalable, low temperature pyroelectrochemical process that can potentially reduce the cost and close the loop of battery cathode recycling.

A catalytic (5+1) cycloaddition of diazooxindoles with imidazolidines is described, providing a general and efficient synthetic route to medicinally attractive piperazine-spirooxindole frameworks in moderate to excellent yields under rhodium or copper catalysis. Moreover, diverse transformations of the obtained products have been achieved to access more complex and even drug-derived spirooxindoles. Importantly, the asymmetric version has also been realized by employing the combination of Cu(OTf)2 and a newly synthesized SaBOX ligand (L5), leading to optically active products with up to 93:7 e.r.. This report shows that rhodium and copper are complementary catalysts for this reaction, and that copper is more competent than rhodium in catalytic asymmetric reactions involving diazocarbene-ylide intermediates.

Published: June 2024

Imaging mass spectrometry enables untargeted spatial profiling of compounds in animal tissues. Data preprocessing and mining are central to comprehensively unravel the complexity of hyperspectral imaging mass spectrometry experiments. Herein, we describe a user-friendly, partially GPU- or compiler-accelerated software pipeline that enables multi-ROI, multi-condition, and multi-replicate preprocessing and mining of larger-than-memory imaging mass spectrometry datasets in Python. The package, termed iMSminer, streamlines computational imaging mass spectrometry workflows, from spectral preprocessing to unsupervised exploratory analysis to univariate fold-change statistical analysis. These capabilities enable mining of ions for molecular co-localization, characteristic molecular profiles, and differential expression. Functions include raw imzML import, peak picking, baseline subtraction, mass alignment, peak integration, normalization, ROI selection, calibration, chemical database search, analyte filtering, image processing, box plot visualization, volcano plot and heatmap visualizations, dimensionality reduction, image clustering, and in situ segmentation. Furthermore, data processed by iMSminer can be easily interfaced to standard deep learning packages and other special-purpose modelling tasks in Python for more advanced use cases.

Ethylene bridged 16π [2.2.2.2] tetrathiaisophlorin represents a novel example for the ring contracted isophlorin, where all the thiophenes are connected only through α, β position, along with E-form of ethylene bridge. It was synthesized through McMurry coupling of appropriate dialdehydes. Single Crystal X-ray diffraction studies displayed the planar con-formation of the macrocycle along with all thiophene and ethylene protons. 1H NMR studies confirms the paratropic ring current of the macrocycle, where all the ethylene protons resonate in downfield. Two 8π cyclooctatetraenes, were isolated as racemic mixture having the puckered 4nπ ring.

Published: June 2024

In this paper we evaluate the distributional impact of carbon pricing in Ireland via a number of different measures, Excise Duties, Carbon Taxes and the EU Emissions Trading Scheme, utilising information contained in the OECD Effective Carbon Rate (ECR) database together with the PRICES model. Essential household energy consumption constitutes a significant portion of spending, particularly for lower-income households, indicating regressive expenditure patterns across income brackets. The immediate impact of carbon pricing on household budgets varies based on their reliance on various fuels for heating and transportation (direct impact), as well as the emissions associated with other goods and services (indirect impact). Carbon footprints vary widely among households, with higher-income ones generally emitting less than lower-income ones as a percentage of their income. Although carbon footprints primarily dictate the burdens of carbon pricing, other factors such as the uneven application of carbon pricing policies and disparities in emissions between industries and fuel types also influence the equation. Despite the necessity for substantial carbon price hikes to meet climate targets, the effects on household budgets during the 2012-2021 period were relatively modest. Carbon pricing reforms typically exhibited regressive trends, disproportionately affecting lower-income households relative to their earnings. We modelled also a number of different reforms utilising the revenue generated by the additional carbon revenues. The net impact in terms of winners and losers depended very significantly upon the both the nature of the expenditure and upon the share of revenue used.

Background: Soft liners in dentures play a crucial role in enhancing patient comfort and preventing tissue irritation especially for patients with resorbed ridges. However, microbial colonization presents a challenge to their long-term effectiveness, particularly Candida albicans, leading to conditions like denture-induced stomatitis. Objective: To evaluate the antimicrobial efficacy and mechanical properties of heat cured soft liners incorporating plant extracts from Olea europaea and Ficus carcia, individually and synergistically. Patients and Methods: Extracts were obtained through Soxhlet extraction, and their antimicrobial activity against Candida albicans was determined using the broth microdilution method. Soft liner specimens were prepared with varying concentrations of the extracts and subjected to disk diffusion tests, shore A hardness measurements, and peel bond strength tests. Statistical analysis involved the use of one-way ANOVA and Dunnett tests. Results: Results demonstrated significant antimicrobial activity, with the synergistic mixture exhibiting the highest inhibition zone against Candida albicans. Moreover, the addition of such extracts led to increased shore A hardness, with the highest levels recorded for synergistic groups. The extracts also displayed a significant decrease in peel bond strength, indicating potential challenges in adhesive properties. These findings suggest that while individual extracts show promise in antimicrobial efficacy and mechanical reinforcement of soft liners, their combination may lead to compromised adhesive properties. Conclusion: The study contributes valuable insights into the development of antimicrobial soft liners reinforced with Olea europaea and Ficus carcia extracts, advancing dental materials towards improved patient outcomes and enhanced oral health. Keywords: Soft liner, Olea europaea, Ficus carcia, Disk diffusion, Compressive strength.
