incorporación de las ciencias biológicas a la Big Science
Authors: Infiesta Molleda Pablo
Published: January 2023

El examen de los actores, instituciones y materiales implicados en el Proyecto Genoma Humano (PGH) remite inmediatamente al contexto de los macroproyectos científicos que suelen caracterizarse con el expresivo rótulo de «Big Science». Como es bien sabido, la afortunada expresión fue acuñada por el sociólogo de la ciencia Derek de Solla Price en 1936 quien elaboró su concepción considerando, principalmente, a la física de su época. Sin embargo, las ciencias biológicas tardaron varios decenios más en adquirir las dimensiones de la Big Science. En el caso del PGH se presenta un panorama muy distinto al contexto en el que surgió la estructura de la doble hélice. El investigador aislado no tiene cabida en este contexto, y los grandes científicos son ahora directores de proyectos y el caso de James Watson es de nuevo paradigmático.

Authors: Mlčáková Renata , Maštalíř Jaromír , Lukášová Kateřina
Published: January 2023

Cílem studie bylo ověřit v praxi diagnostickou pomůcku TETRECOM, a to u žáků základních škol běžného typu (ZŠ) a základních škol logopedických (ZŠL). Výzkumný vzorek zahrnoval 71 dětí z 2. ročníků, z toho ze ZŠL (n = 34) a ze ZŠ (n = 37). Pomůcka zjišťuje znalost čtení izolovaných písmen a je založena na technologii eye tracking. Dílčími cíli bylo zjistit u vybraného vzorku žáků, jaké jsou rozdílnosti v čtení velkých/malých a tiskacích/psacích písmen; ověřit, zda existují významné rozdíly v úspěšnosti čtení písmen u žáků dle typu školy; zda existují významné rozdíly v délce trajektorie očních pohybů při čtení písmen u žáků dle typu školy; zda jsou významné rozdíly v úspěšnosti čtení písmen všech typů u žáků s odkladem školní docházky (n = 34) a výsledky žáků bez odkladu školní docházky (n = 37). Sběr empirických dat se uskutečnil v období 9–10/2020. Z metod sběru empirických dat jsme uplatnili čtyři nestandardizované testy vlastní konstrukce: čtení malých tiskacích písmen, čtení velkých tiskacích písmen, čtení malých psacích písmen a čtení velkých psacích písmen; eye tracking pomocí Tobii4C a software TETRECOM vytvořený na naši zakázku. Výsledky: Žáci ze ZŠ dosáhli v průměrném skóre ve čtení všech typů písmen statisticky signifikantně vyššího výsledku než žáci ze ZŠL (malá tiskací písmena p < 0,001; velká tiskací písmena p < 0,001; malá psací písmena p < 0,001 a velká psací písmena p < 0,001). Testovaná délka trajektorie očních pohybů u všech testů byla u žáků na ZŠL statisticky významně vyšší než u žáků na ZŠ (malá tiskací písmena p = 0,005; velká tiskací písmena p = 0,02; malá psací písmena p = 0,014 a velká psací písmena p = 0,008). Děti bez odkladu školní docházky dosáhly ve všech testech čtení písmen statisticky významně vyšších výsledků než děti s odkladem školní docházky (malá tiskací písmena p = 0,002; velká tiskací písmena p = 0,002; malá psací písmena p = 0,001 a velká psací písmena p < 0,001). Měření očních pohybů nabídlo detailnější pohled na strategie čtení u každého dítěte.
Heterogenita ve způsobu odpovídání na dotazníkové položky u českých žáků v PISA 2012 : analýza dle kraje, typu a velikosti školy
Authors: Voňková Hana , Papajoanu Ondřej , Boško Martin
Published: January 2023

Rozdíly ve způsobu odpovídání na dotazníkové položky mezi žáky mohou zkreslit data (nejen) z mezinárodních výzkumů. Na vzorku z PISA 2012 zkoumáme, jak se liší způsob odpovídání českých žáků s vybranými charakteristikami (gender, vzdělání rodičů) na různých školách (kraj, typ a velikost školy) a jak způsob odpovídání souvisí s jejich výsledky v testech. Způsob odpovídání určujeme pomocí identifikace tendence souhlasit, analýzy chybějících odpovědí, metody identifikace nadhodnocování vlastních znalostí (MINa) a hodnocení ukotvujících vinět. Významné rozdíly ve způsobu odpovídání mezi žáky jsou zejména dle kraje, typu školy a genderu, a to například v hodnocení ukotvující viněty popisující nejnižší úroveň učitelova řízení třídy. Výsledky žáků v testech výrazně souvisejí se způsobem odpovídání na individuální i školní úrovni, např. korelace mezi čtenářskou gramotností a MINa indexem přesnosti je 0,49 a 0,71. Další výzkum se může zaměřit i na jiné přístupy, např. analýzu časů odpovídání na položky.

Effects of Education Equalization Measures on Housing Prices: Evidence from a Natural Experiment in Suzhou, China
Authors: Xie Shang , Reman Muhammad  Ateeq ur , Mao Kang
Published: January 2023

Educational equity is the foundation of social equity, and education equalization is one of the serious issues to be solved by the government. This work considers one education equalization reform conducted by Suzhou Industrial Park of China, namely, the comprehensive "five to nine" (CFTN) housing purchase admission qualification adjustment policy, as an example and uses the resold housing transaction data to identify the effect of the equalization policy by the difference-in-differences (DID) method. Based on this natural experiment, the quantitative assessment results show that (1) the CFTN policy has a significantly positive effect on housing prices in nine-year consistent (NYC) school districts that belong to high-quality school districts; (2) the CFTN policy has no significant effect on housing prices in non-NYC consistent school districts that belong to ordinary school districts. These results uncover that the one-size-fits-all CFTN policy can only obtain significant housing price equilibrium effects in school districts above a certain level of education quality. For regions with backward education levels, the policy is ineffective. For these regions, continuously increasing high-quality educational resources and increasing educational service levels are essential solutions to reduce educational inequality.

Authors: Kortsari Annie , Mitropoulos Lambros , Heinemann Trine , Mikkelsen Henrik , Aifadopoulou Georgia
Published: January 2023

Europe is an extremely ferry-intensive area, with two main markets – the Northern Europe and the Baltic, and the Mediterranean; while EU ferries account for 35% of the world fleet. This research presents the E-ferry, the first pure electric ferry for medium range routes and likely the largest battery pack ever installed in an electric vessel, and evaluates its economic performance compared to an electric-diesel and a diesel vessel. Three E-ferry schemes are used in the evaluation: E-ferry prototype, E-ferry prototype excluding the development costs, and Series 3 E-ferry, for which we assume an increased production level. The evaluation focuses on the construction and operation costs of the vessels by utilizing real-world data that were collected during the evaluation period of the E-ferry, and complemented with data provided by the ferry operator. The evaluation shows that while the E-ferry construction cost is higher compared to the other two technologies, it contributes significantly to energy demand reduction. The E-ferry achieves cost parity with the diesel-based engine vessels between 5.2 and 3.6 years when considering different E-ferry and energy schemes, showing the potential to promote sustainable ferry operations in short and medium range ferry connections.

Regression Modelling Estimation of Marine Diesel Generator Fuel Consumption and Emissions
Authors: Yüksel Onur , Köseoğlu Burak
Published: January 2023

This study aims to estimate the fuel consumption of marine diesel generators onboard. Objective technical specifications and operational data on the ship's power generating plants and port calls were collected from an oceangoing oil/chemical tanker and used to develop the mathematical model of the plant in the Python and MATLAB environment. The model consists of alternators, prime movers and load distributions of the ship’s power generating plant and provides information on fuel consumption in metric tons calculated based on hours of operation and specific fuel consumption data. Regression models have helped predict future fuel consumption for the plant and the optimal model for the dataset was identified by comparing four different algorithms. As the results have shown the Ordinary Least Squares Regression to be optimum, it was used to make one, five, and ten-year predictions. The predictions for one-year, five-year, and ten-year periods are 4,322,436, 10,684,860, and 18,615,472 t respectively. The selected model predicts fuel consumption with R2 of 0.999, MAE of 3.932, and RMSE of 2.935. Fuel consumption predictions facilitated plant emission calculation.

Published: January 2023

Marine energies are a strategic channel for renewable energies to diversify and complement the global energy mix. From this perspective, several researches have seen the light in order to allow the maximum exploitation possible of the energy estimated at 80,000 TWh/year, presenting multiple vacant possibilities concerning energy not yet exploited on a large scale. The purpose of this paper is the use of ocean vibratory energy coupling with a smart composite material in order to harvest the maximum power. This study will be devoted to the design, modeling, and simulation of a floating harvester energy system that combines the mechanical strength and flexibility of polymer with the high piezo and pyroelectric activities of ceramic. The harvester system is composed of a mass-spring system used to transfer wave movements to mechanical vibrations, and two piezoelectric lever devices will be used to amplify and convert the harvested mechanical vibration into electrical power. With this flexible device, the maximum power harvested is 56.45 μW/mm², using PU/PZT composite with the optimal resistance of 108 MΩ. Considering these results, this system can be used in very different ways in marine applications.
Relationship Between the Big Five Personality Traits and Job Satisfaction – A Pilot Study on a Sample of Croatian Seafarers
Authors: Slišković Ana , Russo Andrea , Mulić Rosanda
Published: January 2023

Over the past decade, research on seafarers' health, well-being, stress, and job satisfaction has increased. Previous studies on other work populations have shown the relationship between the Big Five personality traits and job satisfaction, but the significance of each trait of the Big Five model, as well as the size of the correlations, vary according to the characteristics of the samples, such as gender, age, and occupation. With a view of the lack of addressing this research topic in seafarers, this study aimed to examine the relationships between the five basic personality dimensions and seafarers' job satisfaction. The convenient sample consisted of 286 Croatian male seafarers aged between 18 and 65. Participants completed a questionnaire that included questions on sociodemographic characteristics, IPIP-50 inventory measuring five personality traits, Job Satisfaction Scale, and Seafarers' Job Satisfaction Scale. The results showed that both measures of job satisfaction correlated positively with emotional stability, conscientiousness, and extraversion. However, the general measure of job satisfaction additionally correlated positively with intellect/imagination, while the measure of maritime job satisfaction additionally correlated positively with agreeableness. Among the five personality traits, emotional stability proved to be the highest correlate for both measures of job satisfaction. This pilot study reveals significant correlations between the Big Five personality traits and seafarers' job satisfaction. The paper brings theoretical and practical discussions on the relationships between the Big Five personality traits and seafarers' general and specific job satisfaction. The study represents a call for further researchers to verify the obtained results on more representative samples of the seafarer population and to test the predictive validity of personality traits in explaining job satisfaction through longitudinal studies.
Study on the Relationship Between Ship Resistance and Trim, Supported by Experimental and Software-Based Analysis
Authors: Ziylan Kerim , Nas Selçuk
Published: January 2023

In this study, towing tank experiments have been carried out for a container ship under different trim-draft conditions. Experimental results have been interpreted together with the results of the Holtrop method used in both Maxsurf and Orca to identify reactions to changing trim conditions. The study has shown that towing tank experiment findings differ from other relevant findings. The ship shows different resistance characteristics under different trim conditions, but generally the least resistance without trim. In addition, the total resistance change at ship design speed was found to be up to 18% higher in the trim by aft condition. We believe that study findings will help better understand the constantly changing resistance variable depending on draft, speed, and trim conditions.
Port Cities Dynamics in North-Western France: the Cases of Dunkirk, Le Havre and Nantes-Saint-Nazaire
Authors: Loubet Lilian , Serry Arnaud
Published: January 2023

The beginning of the twenty-first century has brought about multiple changes for French ports, such as increased competition and the loss of market share, as well as reforms that have reorganized the national port system. In this context, France’s western coastline constitutes a major stake for the development of the country's foreign trade. Indeed, it is located in an ambivalent position, both closely connected to and at the same time competing with the Northern-Range. Since the large port reform of 2008, the three autonomous ports of France’s western coast (Dunkirk, Le Havre, and Nantes- Saint-Nazaire) have become “Large Maritime Ports” (Grands ports maritimes), or “major seaports” in English. If their institutional governance subscribes to a general model, we can nevertheless observe local specificities which are reinforced by the contemporary merging of the ports of the Seine Axis (Le Havre, Rouen and Paris).Beyond the institutional dimension, therefore, the paper will analyse the decision-making mechanism and structuring of local leaderships according to the representations of the main stakeholders of the three port cities. For this purpose, the representatives of the stakeholders involved were interviewed during a series of consultations, aiming at defining the urban port governance processes in each territory. Thus, the articulation of the scales of power, private-public relations, opposition between port workers’ unions, port authorities or organizations defending the interests of industrial port companies, are expressed through nuances that give substance to port dynamics, as complex as it is subtle.
Prediction of Emergency Preparedness Level On-Board Ships Using Discrete Event Simulation: the Case of Firefighting Drill
Authors: Tac Burcu Ozturk , Celik Metin
Published: January 2023

This paper proposes a hybrid approach, including Fuzzy Dematel (FD) integrated with Discrete Event Simulation (DES), to predict emergency preparedness levels on-board ships. The FD used critical factors that affect emergency preparedness to conduct a DES based on real firefighting drill records collected from 45 merchant ships. The simulation results showed the average duration of on-board drills in ideal conditions (27.47 min.), in the worst-case scenario (51.49 min.), for Ship A (29.99 min.), and Ship B (28.12 min.). Based on the findings, recovery actions linked to the factors have been recommended to promote on-board implementation. The proposed model is of great importance to shore-based managers, allowing them to monitor the emergency preparedness level of the fleet continuously, even during pandemics. Further studies are planned to develop a remote monitoring system that would digitalize the existing response procedures in emergency situations.
Assessment of Role of Admiralty Courts in India in Protecting Abandoned Seafarers Onboard Vessels in Indian Ports
Authors: Gupta Mohit , Shanthakumar Sanjeevi
Published: January 2023

The present study will discuss the role of admiralty courts in India in protecting abandoned seafarers. Judgments and orders of Admiralty courts are analyzed to decipher the approach adopted by Indian admiralty courts for protecting abandoned seafarers in Indian Ports. Furthermore, it is seen how much time Admiralty Courts in India usually take to judicially auction the vessel in cases where the vessel under arrest has an abandoned crew onboard. Several suggestions are made on how Admiralty courts in India can better protect abandoned seafarers by using the existing legal regime. The study is doctrinal. A significant data source for the study comprises Judgments and orders from Indian Admiralty courts involving abandoned seafarers. In particular, five specific instances where seafarer abandonment was reported on the vessel are assessed, and all of these cases were litigated in the Indian Admiralty court. From work, it can be seen that Admiralty courts in India have played a crucial role in protecting the abandoned seafarers in Indian Ports. Courts have come out as a guardian of seafarers, and it was only due to the intervention of the courts that the seafarers, in numerous cases, were able to recover pending wages, repatriation expenses, and necessities onboard the vessel. Furthermore, it is found from the analysis of case laws that the time the court takes for judicially auctioning the vessel is much longer than the maximum period specified in the Admiralty Act, 2017. From the study, it can be concluded that although Admiralty courts in India have played an important role in protecting abandoned seafarers in Indian ports, still, there is a need for some changes, which include speedy disposal of admiralty litigations in India.
Right of Issuing Bank to be Subrogated to the Applicant of Letter of Credit Under the Insurance Contracts
Authors: Al-Daboubi Derar
Published: January 2023

This article discusses the case where the efforts of the issuing bank prove futile to recovering the payment - paid to the beneficiary - from the applicant of the letter of credit. In particular, when the sold goods - the subject matter of the letter of credit - received damaged or lost. This scenario is envisaged when the applicant refuses to make the payment imposed under the letter of credit. The necessity of discussing this matter is to clarify whether or not the issuing bank can be subrogated to the beneficiary’s rights acquired under insurance contract. The analysis will focus on the English law and Uniform Customs & Practice for Documentary Credits (UCP600), in order to illuminate the legal grounds on which the issuing bank can stand so as to enjoy such rights, through which the paid fund can be reimbursed.
Energetyka rozproszona jako element uniezależniania Polski od zewnętrznych wstrząsów
Authors: Kurtyka Michał
Published: January 2023

Po agresji Rosji na Ukrainę rozwój energetyki rozproszonej powinien nabrać przyspieszenia. To najszybszy sposób na zbudowanie nowych mocy wytwórczych, które pozwolą ograniczyć zależność Polski od importowanych węglowodorów, a także szansa na zaangażowanie kapitału prywatnego, a docelowo również na zwiększenie odporności kraju na zewnętrzne wstrząsy. Artykuł zawiera postulat osadzenia rozwoju energetyki rozproszonej na czterech fundamentach, którymi są: rozwój regulacji, modernizacja i dostosowanie infrastruktury, inwestycje w postęp technologiczny oraz edukacja i wymiana doświadczeń. Energetyka rozproszona zasługuje na przyjęcie kompleksowej strategii rozwoju (jej propozycja została opracowana w ramach projektu Gospostrateg na potrzeby Ministerstwa Klimatu i Środowiska), a także na zmianę definicji. W artykule przedstawiono propozycję, by definiować ją w odniesieniu do kryteriów mniej technicznych niż ma to miejsce obecnie, a bardziej odzwierciedlić cel istnienia, na przykład dążenie do samobilansowania.
A super-resolution network using channel attention retention for pathology images
Authors: Jia Feiyang , Tan Li , Wang Ge , Jia Caiyan , Chen Zhineng
Published: January 2023

Image super-resolution (SR) significantly improves the quality of low-resolution images, and is widely used for image reconstruction in various fields. Although the existing SR methods have achieved distinguished results in objective metrics, most methods focus on real-world images and employ large and complex network structures, which are inefficient for medical diagnosis scenarios. To address the aforementioned issues, the distinction between pathology images and real-world images was investigated, and an SR Network with a wider and deeper attention module called Channel Attention Retention is proposed to obtain SR images with enhanced high-frequency features. This network captures contextual information within and across blocks via residual skips and balances the performance and efficiency by controlling the number of blocks. Meanwhile, a new linear loss was introduced to optimize the network. To evaluate the work and compare multiple SR works, a benchmark dataset bcSR was created, which forces a model training on wider and more critical regions. The results show that the proposed model outperforms state-of-the-art methods in both performance and efficiency, and the newly created dataset significantly improves the reconstruction quality of all compared models. Moreover, image classification experiments demonstrate that the suggested network improves the performance of downstream tasks in medical diagnosis scenarios. The proposed network and dataset provide effective priors for the SR task of pathology images, which significantly improves the diagnosis of relevant medical staff. The source code and the dataset are available on https://github.com/MoyangSensei/CARN-Pytorch.
Organizational Support for Entrepreneurial Orientation: The Perception of Professionals from Early Childhood Education Centers in Brazil
Authors: dos Santos Vieira Luciana , Meirelles Daniela Andrade , Emmendoerfer Magnus
Published: January 2023

Entrepreneurial Orientation (EO) has become increasingly prominent in the public sector and in educational organizations. A policy for educational management based on EO has dimensions related to innovation, proactiveness, and risk-taking, which are preceded by organizational characteristics such as management support, discretion/autonomy, rewards/recognition, organizational boundaries, and time availability. The objective of this study is to analyze the organizational characteristics that influence EO in Municipal Centers for Early Childhood Education (Centros Municipais de Educação Infantil - CEMEIs) in Brazil. The study was conducted in a town in the state of Minas Gerais and involved 15 CEMEIs, applying questionnaires to education professionals as coordinators, monitors, and teachers, whose data were processed using descriptive statistics and a structural equation model. The results present a construct for validating organizational characteristics that can influence EO in public early childhood education organizations. However, autonomy and management support were the determinants of EO in the organizations studied. Finally, there are implications and considerations for policies and strategies in public educational organizations, indicating EO as a way to deal with contingencies, resource scarcity, the stimulation of (intra)entrepreneurial culture and even potential early childhood education for entrepreneurship.
Raising Primary School Boys’ and Girls’ Awareness and Interest in STEM-Related Activities, Subjects, and Careers: An Exploratory Case Study
Authors: McMaster Natalie , Carey Michael David , Martin David Allen , Martin Janet
Published: January 2023

Internationally, there is an under-supply of intellectual capital to provide for STEM-related employment. One contributing factor is the low number of female students selecting STEM school subjects and careers. Despite the literature recommending students engage in STEM activities earlier, many initiatives are not implemented until high school. This paper reports on an Australian project named MindSET-do which provided students with early positive STEM experiences prior to high school to raise awareness of, interest in, and aspirations for STEM-related subjects and careers. The case study surveyed n = 107 Year 6 boys’ and girls’ interests, ability beliefs and expectations in STEM school subjects and careers. Students’ awareness and interest in STEM-related subjects and careers increased significantly following experiences with inquiry-based STEM activities, χ2(1, n = 107) = 4.57 to 63.67, p < .05. Expectancy for success in mathematics was significantly higher for males than for females (U = 1125, p = .044, r = .2). Expectancy for success in science was slightly lower for the female group, but p > .05. Logistic regression found females were 24 percent less likely to have a positive view of mathematics than males (p = .003). Gender differences in STEM ability versus ability beliefs and expectancies for success are discussed, with recommendations for earlier positive experiences with STEM tasks.

In the context of Artificial Intelligence, Generative Adversarial Nets (GANs) allow the creation and reproduction of artificial data from real datasets. The aims of this work are to seek to verify the equivalence of synthetic data with real data and to verify the possibilities of GAN in educational research. The research methodology begins with the creation of a survey that collects data related to the self-perceptions of university teachers regarding their digital competence and technological-pedagogical knowledge of the content (TPACK model). Once the original dataset is generated, twenty-nine different synthetic samples are created (with an increasing N) using the COPULA-GAN procedure. Finally, a two-stage cluster analysis is applied to verify the interchangeability of the synthetic samples with the original, in addition to extracting descriptive data of the distribution characteristics, thereby checking the similarity of the qualitative results. In the results, qualitatively very similar cluster structures have been obtained in the 150 tests carried out, with a clear tendency to identify three types of teaching profiles, based on their level of technical-pedagogical knowledge of the content. It is concluded that the use of synthetic samples is an interesting way of improving data quality, both for security and anonymization and for increasing sample sizes.

The main objective of this study is the design and validation of an educational methodological model based on the use of immersive technological resources (Augmented Reality – AR) to improve learning processes in secondary education science subjects (Biology and Geology). The process was developed based on three main quantitative studies: an exploratory study, a study of performance divided into three cases studies, and an attitudinal study. The information obtained was completed with a fourth qualitative study of the training of teachers who participate in educational technology. This research provides empirical evidence that allows validation of the methodological model developed to explain key concepts and to improve the level of motivation and acceptance of AR technology by students. The proposed model can induce improvements in educational processes in the field of STEAM when used with an immersive AR technological resource and an adapted digital evaluation system. It also demonstrates that teachers require specific training in connection with the creation and the adequate use of AR educational resources, and of digital evaluation systems as well. The results of this study have important implications for the field of education, demonstrating the potential of AR technology to improve learning outcomes and the need for teacher training in its use.

Published: January 2023

2D metal carbides and nitrides (MXene) are promising material platforms for on‐chip neural networks owing to their nonlinear saturable absorption effect. The localized surface plasmon resonances in metallic MXene nanoflakes may play an important role in enhancing the electromagnetic absorption; however, their contribution is not determined due to the lack of a precise understanding of its localized surface plasmon behavior. Here, a saturable absorber made of MXene thin film and a silicon waveguide with MXene flakes overlayer are developed to perform neuromorphic tasks. The proposed configurations are reconfigurable and can therefore be adjusted for various applications without the need to modify the physical structure of the proposed MXene‐based activator configurations via tuning the wavelength of operation. The capability and feasibility of the obtained results of machine‐learning applications are confirmed via handwritten digit classification task, with near 99% accuracy. These findings can guide the design of advanced ultrathin saturable absorption materials on a chip for a broad range of applications.

CO2 utilization and conversion are of great importance in alleviating the rising CO2 concentration in the atmosphere. Here, a single‐atom catalyst (SAC) is reported for electrochemical CO2 utilization in both aqueous and aprotic electrolytes. Specifically, atomically dispersed Mn–N4 sites are embedded in bowl‐like mesoporous carbon particles with the functionalization of epoxy groups in the second coordination spheres. Theoretical calculations suggest that the epoxy groups near the Mn–N4 site adjust the electronic structure of the catalyst with reduced reaction energy barriers for the electrocatalytic reduction of CO2 to CO. The resultant Mn‐single‐atom carbon with N and O doped catalyst (MCs‐(N,O)) exhibits extraordinary electrocatalytic performance with a high CO faradaic efficiency of 94.5%, a high CO current density of 13.7 mA cm−2, and a low overpotential of 0.44 V in the aqueous environment. Meanwhile, as a cathode catalyst for aprotic Li–CO2 batteries, the MCs‐(N,O) with well‐regulated active sites and unique mesoporous bowl‐like morphology optimizes the nucleation behavior of discharge products. MCs‐(N,O)‐based batteries deliver a low overpotential and excellent cyclic stability of 1000 h. The findings in this work provide a new avenue to design and fabricate SACs for various electrochemical CO2 utilization systems.

The encapsulation of bevacizumab (BVZ), angiogenesis inhibitor antibody, into nanocarriers is explored aiming at enhancing its efficacy in colorectal cancer (CRC) treatment while eliminating potential side effects. Still, the translation of such nanomedicines into clinics is not straightforward owing to their preclinical screening in simplistic models, that do not mimic the complexity and heterogeneity of the CRC microenvironment. Herein, the development of a multicellular spheroid of CRC as an advanced preclinical model of CRC capable of screening the antiangiogenic potential of novel nanomedicines is proposed. For that, a quadruple co‐culture is established through the combination of HCT116 cells, human pulmonary microvascular endothelial cell (HPMEC), fibroblasts, and macrophages. It is demonstrated that the developed model displays intrinsic CRC features, such as the organization of cells, expression of tumor microenvironment, extracellular matrix, and the formation of a necrotic core. Moreover, the model is shown to be composed mostly of HCT116 (93%), followed by hypoxia‐inducible factor (3%), HPMEC (3%), and macrophages (1%). Gellan gum/chitosan nanoparticles encapsulating BVZ exhibit superior antiangiogenic properties when compared to free BVZ. Overall, the developed nanoparticles can further be explored as a promising approach in CRC treatment.

Published: January 2023

Highly permeable acid‐resistant nanofiltration (NF) membranes are of critical significance for the efficient treatment of acidic streams. Enhancing permeability while maintaining the high solute rejection of acid‐resistant NF membranes remains a great challenge due to the low reactivity of monomers. In this work, a novel catalytic template assisted interfacial polymerization (IP) strategy of 3‐aminobenzenesulfonamide (ABSA) and trimesoyl chloride (TMC) was provided to prepare a poly(amide‐sulfonamide) membrane. Aminopyridine doped graphene quantum dots rich in acylation catalytic sites and ZIF‐8 nanoparticles are co‐loaded on a substrate as template. Benefiting from the enhanced phase integrity and self‐inhibition effect of the template assisted IP process, the resulting ultra‐thin acid‐resistant membrane exhibits an excellent water permeance (20.4 Lm−2h−1bar−1) with a high Na2SO4 rejection of 90.5%, which outperforms almost all the reported acid‐resistant NF membranes. Our work paves a versatile way for synthesis of special separation membranes.
Intensified reactor for lean methane emissions treatment
Authors: Irhamna Adrian R. , Bollas George M.
Published: January 2023

The Global Methane Pledge declared at the 2021 United Nations climate change conference (COP26) marked the world's commitment to eradicate methane emissions. Regardless of the source, methane emissions are typically generated in a lean composition (e.g., <1% vol), remote and scattered. This work explores the use of an intensified reactor that implements the chemical looping principle to handle lean methane emissions. A model‐based framework is used to showcase the baseline performance of the proposed reactor in converting methane emissions using nickel‐based oxygen carriers. Sensitivity analysis of the reactor showed that the Ni percentage in the oxygen carrier, the feed air temperature, feed air to flared gas ratio, and oxidation to reduction duration ratio are the most deciding variables for reactor performance. The reactor is subsequently optimized to minimize the methane emitted, using a dynamic program with safety and operability constraints for the alternating redox process. With the optimal cycle strategy, we demonstrate that near‐complete methane conversion (>98% methane conversion) can be achieved by the reactor without external heating.

Objective

Rapid eye movement (REM) sleep is markedly altered in Alzheimer's disease (AD), and its reduction in older populations is associated with AD risk. However, little is known about the underlying brain mechanisms. Our objective was to investigate the relationships between REM sleep integrity and amyloid deposition, gray matter volume, and perfusion in aging.

Methods

We included 121 cognitively unimpaired older adults (76 women, mean age 68.96 ± 3.82 years), who underwent a polysomnography, T1‐weighted magnetic resonance imaging, early and late Florbetapir positron emission tomography scans to evaluate gray matter volume, perfusion, and amyloid deposition. We computed indices reflecting REM sleep macro‐ and microstructural integrity (ie, normalized electroencephalographic spectral power values). Voxel‐wise multiple regression analyses were conducted between REM sleep indices and neuroimaging data, controlling for age, sex, education, the apnea‐hypopnea index, and the apolipoprotein E ε4 status.

Results

Lower perfusion in frontal, anterior and posterior cingulate, and precuneus areas was associated with decreased delta power and electroencephalographic slowing (slow/fast frequencies ratio), and increased alpha and beta power. To a lower extent, similar results were obtained between gray matter volume and delta, alpha, and beta power. In addition, lower REM sleep theta power was more marginally associated with greater diffuse amyloid deposition and lower gray matter volume in fronto‐temporal and parieto‐occipital areas.

Interpretation

These results suggest that alterations of REM sleep microstructure are associated with greater neurodegeneration and neocortical amyloid deposition in older adults. Further studies are warranted to replicate these findings, and determine whether older adults exhibiting REM sleep alterations are more at risk of cognitive decline and belonging to the Alzheimer's continuum.
