В работе исследуется влияние компоновки рулевых органов ракеты космического назначения (РКН), на наиболее критичном участке полета I ступени, на эффективность системы управления. В качестве рулевых органов рассматриваются маршевые поворотные двигатели с изменяющимся вектором тяги. В настоящие время в России приложены значительные усилия по созданию многоразовых РКН, которые позволят снизить затраты на производство, а также повторное использование I ступени позволит уменьшить зону посадки, что положительно скажется на экологии окружающих зону районов. При разработке перспективной многоразовой ракеты космического назначения анализ влияния количества двигателей и варианта их компоновок на устойчивость и управляемость позволит прогнозировать целесообразность выбора схемы расположения данных двигателей, на этапе эскизного проектирования. Анализ проводился в каналах тангажа и рыскания, при использовании уравнения возмущенного движения РКН. Проведенный расчет зависимости управляющего и возмущающего момента от времени полета, а также загрузки органов управления позволил исключить неприемлемые схемы и выбрать наиболее перспективные и эффективные варианты расположения маршевых двигателей РКН. На ранних этапах создания многоразовых РКН полученный результат станет необходимым инструментом для решения задач по обеспечению управляемости на стадии предварительного проектирования, и оценки степени унификации маршевых двигателей возвращаемых блоков I и II ступени.
Impact of mindfulness-based interventions on stress reduction: An empirical study in Tirunelveli city
Authors: R. Jeya Rani  , T. Priyanka
Published: July 2023

This research study aimed to investigate the impact of mindfulness-based interventions on stress reduction. The study utilized a pre- and post-intervention design to assess changes in stress levels among participants who engaged in a mindfulness-based intervention program. The sample consisted of 100 individuals from Tirunelveli city. Participants completed a questionnaire assessing their stress levels before and after the intervention program. The questionnaire also included items related to relaxation, mindfulness awareness, coping with stress, and overall well-being. Descriptive statistics, including means and standard deviations, were calculated for each variable. The results revealed a statistically significant reduction in stress levels following participation in the mindfulness-based intervention. The mean stress levels decreased from pre-intervention mean 3.48 to post-intervention mean 2.41, indicating a significant improvement in stress management. This finding suggests that mindfulness-based interventions have a positive impact on stress reduction. Furthermore, participants reported higher scores for relaxation, mindfulness awareness, coping with stress, and overall well-being after the intervention. These results suggest that the mindfulness-based intervention not only reduced stress but also enhanced various aspects of psychological well-being.

Published: July 2023

For several decades coronary bypass grafting has been considered the gold standard treatment for unprotected left main coronary artery lesions. However, the anatomic accessibility and the large caliber of the vessel render the percutaneous coronary intervention a very attractive treatment option for left main coronary artery lesions. The use of percutaneous coronary intervention in this subset of lesions has been further expanded as a result of the introduction of newer drug-eluting stents along with rapid advancements in techniques, devices, and adjunctive pharmacotherapies. The current evidence has demonstrated that patients with low or intermediate coronary complexity treated with percutaneous coronary intervention or coronary bypass grafting have comparable outcomes, for up to 10 years. Treatment of left main bifurcation lesions remains technically demanding despite recent developments. The provisional approach is the default strategy in most types of left main bifurcation lesions. However, a few complex left main bifurcation lesions would warrant an elective two-stent technique. An integrated approach incorporating custom- tailored techniques, adjunctive physiological and morphologic evaluation, and pharmacologic agents is critical to tackle this unique challenge and improve clinical outcomes.
Uzasadnienie orzeczeń sądowych – wybrane problemy

Published: July 2023

The justification of judicial decisions is an important research segment of jurisprudence and, at the same time, a very useful instrument in practice, with multiple – constantly discovered, not fully recognised and valued functions. First of all, it is, as a rule, an inseparable element of a judicial decision and a component of a fair trial. Its jurisprudential functions naturally come to the fore. In the considerations undertaken, emphasis is placed on the multilateral determinants and changing paradigms of legal culture. Judicial jurisprudence remains an inherent part of it. The presented material captures the theme of the evolution that is taking place in the model of law – from an autonomous idea, through a closed concept, to a model of law in which facts are relevant. Social changes, characterised by responsiveness in the approach to the interpretation and application of law, are also described.
IMPACT OF PERCEIVED SATISFACTION OF ORGANISATIONAL CLIMATE ON RETENTION –EVIDENCE FROM NURSING STAFF IN A LEADING PRIVATE HOSPITAL IN SRI LANKA

Published: July 2023

Even though many years have passed, organisations continually focus on retaining Labour resources. Especially, Sri Lankan Nursing Staff tend to decrease their likelihood of continuing in hospitals, and it becomes a critical issue for the entire healthcare industry in Sri Lanka. Thus, the present study attempts to assess the impact of perceived satisfaction of the organisational climate on the intention of retention of nursing staff of a leading private hospital in Sri Lanka. The study uses a quantitative approach. The primary data were collected using a standard questionnaire, and a simple random sampling technique was used to select a sample from the population. Thus, every respondent has an equal contribution to select from the sample. 108 nursing staff in a selected leading private hospital were used as sample respondents. Correlation and regression analysis was used to analyse the gathered data. The findings of this research show a significant impact of perceived satisfaction of the organisational climate on the retention of nursing staff in a leading private hospital. The practical implications of hospitals, managers, and industrial psychologists guide favorable organizational climate physically and mentally which impact the retention decision of the nursing staff.

Keywords: Retention, Perceived satisfaction of organisational climate, Human relations, Internal process
Geological Environment and Controlling Factors of Panlongdong Karst Cave in Northeastern Sichuan Basin

Published: July 2023

The karst landforms in northeastern Sichuan Basin are widely developed, but the understanding of the geological characteristics, controlling factors, and spatiotemporal evolution process of karst caves is still unclear. The research object of this study is the Panlongdong karst cave in the northeastern Sichuan Basin. An outcrop geological survey was carried out, 14C isotope dating of stalactite was performed, carbon and oxygen isotope analysis was completed, and the formation process was identified. The interior of this cave is covered with karst sediments, and its original rocks are the Permian Wujiaping and Changxing formations, with secondary dissolution that has developed. The rock types, geological structure (fault, joint), and climate are the main factors behind the formation of the Panlongdong karst cave. The sedimentation of biogenic reefs and carbonate rocks is a fundamental geological condition for the development of karst processes. The geological structures provide channels for the dissolution of atmospheric precipitation. From 43.5 ka.B.P., six continuous changes in climate have intensified the formation of karst landforms. Warm, humid, and cold dry climate conditions have repeatedly occurred, and carbonate rocks have experienced varying degrees of karstification under the influence of climate. Through the four stages of structural breakup and surface dissolution, secondary cranny dissolution, selective dissolution, and detachment of rock mass and karst sediment formation, the Panlongdong karst cave was ultimately formed. The formation process of the Panlongdong karst cave is of great significance for understanding the evolution of the paleoenvironment in the northeastern Sichuan Basin.
Clustering populations by health and social care with multiple long-term conditions: a cohort study — the English Longitudinal Study of Ageing (ELSA)
Authors: Dambha-Miller Hajira , Nartey Yvonne , Khan Nusrat , Simpson Glenn , Lin Sharon , Akyea Ralph , Farmer Andrew
Published: July 2023

Background

The integration of health and social care services is a potential solution for improving care, despite monetary constraints and increasing demand. How two or more multiple long-term conditions (MLTC) cluster, interact and associate with socioeconomic factors, and affect access to unscheduled primary healthcare services is understudied.

Aim

To cluster an MLTC population by health and social care, examine clusters, and quantify associations with health outcomes.

Method

A retrospective cohort study was conducted using the ELSA database (2002 to 2019) on 19802 participants aged ≥50 years. Ten major health conditions, and social care need, including difficulty in activities of daily living (ADL) and mobility, for example, were used to cluster MLTC by latent class modelling. Multivariate logistic regression models were used to establish further association.

Results

The mean age of the participants at baseline (wave 2) was about 66 years and 55% of participants were female, with more than 60% developing MLTC in their lifetime (waves 2 to 9). Of the five distinct latent clusters, cluster 5 was the most significant cluster composed of lung diseases, stroke, dementia, and high ADL and mobility difficulty scores. The majority of the participants were aged 70–79 years, female, and married. The odds of having a longer nursing home stay were 8.97 (95% confidence interval = 4.36 to 18.45), and death was 10% higher in this cluster compared to the highest probability cluster 4 in the maximally adjusted regression model.

Conclusion

This study identified MLTC clusters by social care need with the highest primary care demand. Targeting clinical practice to prevent MLTC progression for these groups may lessen future pressures on primary care demand.
How Do Hispanic-Serving InstitutionsServe Latinx Students? A PanelAnalysis of Institutional Characteristics and 6-Year Graduation Rates
Authors: Kim Sooji , Parsons Sarah , Franklin Kimberly , Parker Alyse Gray
Published: July 2023

This study builds on the body of research on Hispanic-Serving Institutions (HSIs) and Latinx student outcomes, and uses Garcia et al.’s (2019) conceptual framework of servingness. Using multiple years of data from the Integrated Postsecondary Education Data System (IPEDS), we examined the extent to which HSIs serve Latinx students in terms of 6-year graduation rates at not-for-profit 4-year institutions. Key findings suggest that the average 6-year graduation rates for Latinx students are lower at HSIs than at non-HSIs. HSIs and non-HSIs have vastly different institutional characteristics, such as the organizational environment experienced by students and the structural capacity of institutions to respond to students’ needs. Moreover, we find that, at HSIs, neither the share of Latinx students nor the share of Latinx instructional staff promote Latinx students’ 6-year graduation rates. The graduation rates, however, are positively associated with increased institutional spending on research, academic support, and institutional support, which are organizational structures that can respond to students’ needs for academic success, as well as with higher institutional selectivity approximated by an offering of no remedial courses.

The Stock Market Plays a Crucial Role in the Indian Economy: An Empirical Analysis
Authors: - Akshita Masih , - Ashish S. Noel
Published: July 2023

The stock market is a crucial component of the Indian economy and plays a significant role in its growth and development. This abstract aims to explore the role of the stock market in the Indian economy. The stock market serves as a platform for the buying and selling of shares and securities issued by companies. It allows individuals and institutions to invest their surplus funds and generate returns. In India, the stock market is primarily represented by two major exchanges, namely the National Stock Exchange (NSE) and the Bombay Stock Exchange (BSE).One of the key roles of the stock market is to facilitate capital formation in the economy. When companies need funds for expansion, they can raise capital by issuing shares to the public through initial public offerings (IPOs) or rights issues. This process helps in mobilizing savings from investors and channeling them into productive sectors of the economy. By providing this avenue for raising funds, the stock market acts as a vital source of capital for companies, enabling them to grow and generate employment opportunities.

Authors: - Vrushali Vivek Bhosale Kaneri
Published: July 2023

Food is a significant element of culture. Culinary habits are culturally determined. Different communities and nationalities have their respective culinary choices and inhibitions. Further, culinary cultural differences become prominent in the case of the individuals in diaspora. In the basic, homeland – host nation paradigm, food assumes a defining role as cultural assimilation in diaspora, also demands culinary assimilation. An immigrant’s ethnic cultural identity is also defined by the culinary practices. Further, food also is linked with psych-sociology as Roland Barthes observes.
This paper is an attempt to analyse Mohsin Hamid’s novel The Reluctant Fundamentalist, to identify the culinary markers of cultural differences between Pakistani ethnicity and the culture of the host nation – the USA. The paper uses tenants and tools of Cultural Studies and Food Studies to examine the cultural context of the novel. Further, the paper will also focus on the central character, Changez and his efforts to negotiate his identity through a series of culinary situations.

Authors: Salik Dany , Bourguignon Gen-Hua , Saad Alain
Published: July 2023

Purpose:

To describe a rare condition of late traumatic flap avulsion repositioned with rotational misalignment and epithelial ingrowth and its surgical treatment.

Methods:

A 29-year-old man who underwent uneventful bilateral myopic laser in situ keratomileusis surgery 6 years before hit his right eye against the corner of a table, leading to flap avulsion that he replaced as a contact lens.

Results:

The patient presented with rotational misalignment of the flap and diffuse epithelial ingrowth 15 days after the trauma. The cap was lifted, epithelial ingrowth was scraped on both stromal faces, and the interface was generously irrigated after the flap was correctly realigned. Total recovery with 20/20 uncorrected distance visual acuity was achieved at the 2-month follow-up visit.

Conclusions:

This case report describes a rare case of flap avulsion with its replacement. Although this situation seems to be exceptional and severe, proper surgical management and follow-up can lead to a full recovery.

Iconography of the Baptism scene developed from an older layer of fresco painting from around 1530 in the Gračanica monastery exonarthex
Authors: Dimitrijević Aleksandra
Published: July 2023

It is quite certain that the visible frescoes in the exonarthex of the Gračanica Monastery outer narthex do not come from the same period, so their chronological separation and more precise dating are complex. If it is taken into account that it was built in the early thirties of the 14th century, the outer vestibule have been painted after 1330, but those frescoes are not visible today. It was repainted later, during the time of Metropolitan Nicanor around 1530. The scene of the Baptism of Christ (Mt. 3: 13-17, Mk. 1: 9-11, Lk. 3: 21-22, Jn. 1: 29-34) belongs to the time of the Metropolitan Nicanor, and it is located on the eastern wall of the outer chancel, south of the southeastern pilaster. The iconographic analysis of this scene provides an insight into the wide theological education of the painters, as well as a sense of narrative and primarily adherence to good models from the Paleology era. The style of the Gračanica Monastery frescoes, which belong to the period around 1530, was adapted to the program based on tradition. The developed scene of the Baptism of Christ, inspired by the highest role models, emphasizes confidence in composition and performance, expert drawing and fine modelling in combination with an illuminated palette.
Aprendizajes y reconocimiento de alteridades en escenarios universitarios. Dispositivos de intervención psicoeducativas
Authors: Fornasari Mónica Laura
Published: July 2023

En este trabajo interrogamos las problemáticas y dificultades que atraviesan los estudiantes en sus trayectos académicos en la Facultad de Psicología, Universidad Nacional de Córdoba. Nos proponemos darle visibilidad a un malestar que atraviesa los contextos socioculturales e institucionales y afecta sustancialmente la configuración subjetiva de muchos estudiantes que transitan por los espacios universitarios, sin lograr habitarlos. Ponemos foco en este escenario institucional para comprender el modo de construcción del lazo social, el malestar sobrante, la gramática escolar, la transferencia de trabajo, la práctica entre varios, la posición educadora desde la responsabilidad ética del cuidado, el lazo educativo, y las contribuciones desde la pedagogía social. Desde estas nociones interpelamos nuestra práctica profesional para construir nuevos sentidos sobre aquellos dispositivos de intervención y acompañamiento ofrecidos, que habiliten efectos de subjetivación en los estudiantes universitarios, a partir del reconocimiento del Rostro del Otro y su relación con la alteridad (otros, lenguaje y cultura) en la complejidad de los contextos socioculturales actuales
A morte e o objeto
Authors: García Javier
Published: July 2023

Este trabalho tem como objetivo, em primeiro lugar, uma revisão em Freud sobre a relação que se estabelece entre o sujeito e o objeto e de como as percepções são processadas – representações do sujeito com relação ao objeto. Tendo como referência Lacan, Green e outros autores, o objeto é representado em sua função objetalizante (Eros) e em sua função desobjetalizante (Thanatos). O artigo desenvolve sobretudo a pergunta da morte real (não a pulsão de morte), de como é percebida e sentida na psique do sujeito e como o trabalho da elaboração do luto é processado, no caso da perda real do objeto.

Como é a vida da pulsão de morte?
Authors: Francischelli Leonardo Adalberto
Published: July 2023

O presente trabalho aborda parte da trajetória das pulsões, em Freud, que culminou com a teoria dualística: pulsão de vida e pulsão de morte. Registra, além disso, o pensamento de outros autores contemporâneos, que corroboram o pensamento freudiano em que o princípio do prazer dá lugar à compulsão à repetição, porém sem esquecer que os atributos da pulsão de morte estão também a serviço da vida.
desespero arrebatador de Francis Bacon, um pintor estranho
Authors: Mattos Lorete
Published: July 2023

O objetivo do texto é examinar o processo criativo de Francis Bacon, que trabalha uma mistura entre realismo, surrealismo e violência, atravessado pela pulsão de morte. Amparado no texto freudiano de 1919, O Estranho (Das Unheimliche), busca-se refletir sobre as semelhanças do processo criativo de Bacon com a técnica psicanalítica, e com uma autoanálise, nos seus autorretratos. Ao abrir mão de escolhas conscientes e se deixar levar pelo acaso, Bacon exercita algo aproximado à associação livre na análise, abrindo uma fenda por onde o inconsciente possa fluir. Busca um estado mental que permita, ou ao menos favoreça, o afrouxamento das amarras rígidas do superego e lhe possibilite dar vazão à sua agressividade sem culpa. Pintados repetidamente, os autorretratos são a expressão desesperada de sua solidão. Bacon revira analítica e friamente o seu próprio rosto, submetendo-se à mesma violência que imprime nos outros retratos, de modo insatisfeito e obsessivo.
Psicanálise e psicoterapia no Brasil
Authors: Abreu José Ricardo Pinto de
Published: July 2023

Aspectos socioculturais relacionados ao que se denomina cultura pós-moderna, avanços científicos ligados ao desenvolvimento da psicanálise, da psicoterapia, da neurociência, da genética e da psicofarmacologia exigem do psicanalista e do psicoterapeuta um posicionamento de abertura, de troca e de aproximação com as distintas interfaces e métodos. São abordados aspectos do desenvolvimento da psicoterapia e da psicanálise no Brasil ao longo dos últimos 25 anos. São considerados os marcos históricos, e é oferecido um panorama da psicoterapia. São assinaladas modificações na psicopatologia dos pacientes. São identificados os desenvolvimentos técnicos conforme dois percursos seguidos pelos psicoterapeutas, de acordo com sua inclinação ideológica e posicionamento científico. Crenças e apegos ideológicos parecem contribuir para o isolamento dos psicoterapeutas e psicanalistas. A falta de um trabalho integrado, por sua vez, pode impedir o exercício da criatividade e do desenvolvimento no campo. Ao lado de resistências, constatam-se também tentativas de integração. Exigem-se altos padrões éticos aliados à consistente formação e a elevados princípios. Isso poderá implicar o encaminhamento de uma organização profissional para o futuro além das organizações científica e ética já obtidas em alguns casos.
Investigação psicanalítica contemporânea
Authors: Maldavsky David , Costa Gley P. , Oliveira José Facundo , Katz Gildo
Published: July 2023

Os autores pretendem colocar em evidência o valor do Algoritmo David Liberman (um método de estudo da linguagem como expressão da erogeneidade e da defesa) na investigação psicanalítica teórica e clínica. Começam sintetizando o método, que inclui um programa de computador para o estudo das palavras e duas grades, uma para a análise das frases e outra para o estudo dos relatos, todos como expressão da erogeneidade. Na seqüência, examinam questões epistemológicas, sobretudo para salientar o nexo entre o Algoritmo David Liberman (ADL) e as hipóteses metapsicológicas freudianas. A partir dessas considerações, chamam a atenção para uma das linguagens como expressão da erogeneidade: o erotismo oral primário. Essa descrição permite apresentar alguns desenvolvimentos recentes, derivados de investigações de diferentes tipos. Estes desenvolvimentos dizem respeito, por um lado, às características distintivas da retirada narcisista e do restabelecimento do nexo libidinal com o mundo nas caracteriopatias esquizóides e na esquizofrenia.

L12 phase hardening alloys with excellent mechanical properties are of great significance for structural applications. However, low volume fractions of L12 precipitates in conventional alloys (nearly lower than 60%) tend to limit their practical usage, while the strengths of the alloys generally increase with L12 precipitation contents. Herein, a novel high‐entropy alloy (HEA) Ni35Co35Fe10Al8Ti10B2 with ultrahigh concentration L12 precipitates is successfully designed aided by the calculation of phase diagrams (CALPHAD). The volume fraction of L12 precipitates in this HEA is up to 75% and outperforms that of most of traditional superalloys. The novel L12‐strengthened Ni35Co35Fe10Al8Ti10B2 has an ultrahigh tensile yield strength of ≈1.45 GPa, ultimate tensile strength of ≈1.9 GPa, and great ductility of ≈23% at room temperature. The desirable strength–ductility combination is superior to most of conventional superalloys and reported HEAs, mainly due to the presence of ultrahigh concentration L12 precipitates that act as dislocation obstacles and the formation of numerous stacking faults and deformation twining. This work is expected to provide guidance for developing new high‐performance HEAs with an excellent combination of strength and ductility.

Cu‐based single‐atom catalysts (SACs) are regarded as promising candidates for electrocatalytic reduction of nitrate to ammonia (NO3RR) owing to the appropriate intrinsic activity and the merits of SACs. However, most reported Cu SACs are based on 4N saturated coordination and supported on planer carbon substrate, and their performances are unsatisfactory. Herein, low‐coordinated Cu‐N3 SACs are designed and constructed on high‐curvature hierarchically porous N‐doped carbon nanotube (NCNT) via a stepwise polymerization–surface modification–electrostatic adsorption–carbonization strategy. The Cu‐N3 SACs/NCNT exhibits outstanding NO3RR performance with maximal Faradaic efficiency of 89.64% and NH3 yield rate of up to 30.09 mg mgcat−1 h−1 (70.8 mol gCu−1 h−1), superior to most reported SACs and Cu‐based catalysts. The results integrated from potassium thiocyanide poisoning experiments, online differential electrochemical mass spectrometry, in situ Fourier transform infrared spectroscopy, and density functional theory calculations demonstrate: 1) unsaturated Cu is active site; 2) Cu‐N3 SACs/NCNT possesses NO*‐HNO*‐H2NO*‐H2NOH* pathway; 3) low‐coordinated Cu‐N3 sites and high‐curvature carbon support synergetic promote reaction dynamics and reduce rate‐determining step barrier. This study inspires a synergetic enhancement catalysis strategy of creating unsaturated coordination environment and regulating support structure.

Published: July 2023

Developing small‐scale, lightweight, and flexible devices with integrated microactuators is one of the critical challenges in wearable haptic devices, soft robotics, and microrobotics. In this study, a novel fabrication process that leverages the benefits of 3D printing with two‐photon polymerization and flexible printed circuit boards (FPCBs) is presented. This method enables flexible microsystems with 3D‐printed electrostatic microactuators, which are demonstrated in a flexible integrated micromirror array and a legged microrobot with a mass of 4 mg. 3D electrostatic actuators on FPCBs are robust enough to actuate the micromirrors while the device is deformed, and they are easily integrated with off‐the‐shelf electronics. The crawling robot is one of the lightest legged microrobots actuated without external fields, and the legs actuated with 3D electrostatic actuators enable a locomotion speed of 0.27 body length per second. The proposed fabrication framework opens up a pathway toward a variety of highly integrated flexible microsystems.

Traditional approaches for monitoring human gait have severe spatial and temporal restrictions with complex analysis methods and high cost, which are powerless to promote the development of intelligent life involving fitness, sport training, and healthcare. Herein, a portable smart insole system with high spatial resolution and simple manufacturing process to measure plantar pressure distribution anytime, anywhere for gait analysis is proposed. An insole‐shaped array of 104 piezoresistive sensors with highly robust characteristics is assembled, exhibiting a good pressure‐sensing uniformity. The smart insole not only detects the subtle displacement of the center of gravity of the body, but also exhibits a real‐time, high‐resolution thermodynamic diagram of the plantar pressure distribution during human activities. More importantly, the function of motion intelligence identification can be realized by regionalizing and digitizing the whole plantar pressure distribution, achieving an average recognition accuracy of 83.32% among six predefined motions. These results imply that the carbon fiber‐based smart insole can provide an effective approach for convenient gait analysis and motion identification, which has a great potential in the application of future intelligent life.

We have developed an electrochemical reaction for the synthesis of 3‐selenylchromones and deutero‐selenylated chalcones of alkynyl aryl ketones. This method is free from metal catalysts and oxidants, and is regulated by solvents. The reaction conditions are mild, and a wide range of substrates can be employed to produce selenylated chromones and deutero‐selenylated chalcones, displaying potential anti‐inflammatory activities. Furthermore, we have demonstrated the applicability of this approach for the late‐stage deutero‐selenylation of the drug molecule, metochalcone.

Published: July 2023

With increasing energy demands and environmental issues, renewable energy‐related conversion systems have gained significant attention as a potential substitute for traditional fossil fuel‐based energy technologies. First introduced by S.W.Grove in 1838, fuel cells have been extensively developed into many different types, and direct alcohol fuel cells (DAFCs) are of interest as a potential power source because of their large power density, quick start, simplicity, and nearly zero emission. However, the high cost and poor catalytic efficiency of current catalysts are primary barriers to commercializing DAFCs. Designing advanced nanocatalysts for both anode and cathode electrodes is of crucial importance for practical DAFC development; however, a brief evaluation of current progress in electrocatalyst development for the alcohol oxidation reaction (AOR) and oxygen reduction reaction (ORR) is still very little. Herein, recent advances in fuel cell catalysts, mainly focusing on several most active areas (i.e., Pt‐ and Pt‐free‐based catalysts, metal‐free carbon, carbon‐based nonprecious metal composites) are concisely summarized. Also, challenges and prospects for DAFCs are highlighted to supply a comprehensive view for further designing high‐performance DAFC catalysts.
Certifiable management standards, labor productivity, and worker wages: Evidence from the food sector in Vietnam
Authors: Trifkovic Neda
Published: July 2023

Food production and trade have become inseparable from requirements about product quality and safety, as well as social and environmental aspects of production processes. To demonstrate compliance with these requirements, firms adopt voluntary private certifiable management standards (CMS). How these affect trade, organizational performance, and employee outcomes has become an area of active research in the last decade. This paper analyses how standards affect labor productivity and wages using a 3‐year panel of small and medium firms from the food sector in Vietnam covering the period 2010–2014. Even though the prevalence of CMS in the sample is low, the results show that standards improve both labor productivity and wages. However, the difference in the size of the productivity and wage premiums attributable to standards is not significant. This implies that CMS can be a useful management practice for improving firm productivity when combined with a fair compensation of human resources. The findings are important for lower‐income countries facing low rates of adoption of private CMS and the evolving consumer preferences increasingly attuned to the issues of product quality, food safety, and environmental risks. The results are robust to several specification changes and estimation methods, including firm fixed effects, control function, and instrumental variable approach, which take endogeneity of certification into account.

A Prosthetic Hand with Integrated Sensing Elements for Selective Detection of Mechanical and Thermal Stimuli
Authors: Georgopoulou Antonia , Eckey Louisa Marie , Clemens Frank
Published: July 2023

Flexible electronics have gained popularity because of their capability to combine softness and functionality. Soft resistive sensors are susceptible to mechanical stimuli and detecting temperature selectively remains a challenge. In this study, soft flexible thermistors are developed for detecting temperature changes based on the positive temperature coefficient (PTC) effect, selectively. By thermomechanical analysis and differential scanning calorimetry, it is observed that thermoplastic elastomers with higher thermal expansion and semicrystalline morphology result in a sensitive thermistor response. To achieve a high sensitivity in temperature and low sensitivity in the detection of mechanical stimulus, a low‐carbon filler content is required. The opposite trend is seen for the piezoresistive sensors for mechanical strain detection. Both sensory material types are compatible with thermoplastic material extrusion‐based additive manufacturing. The method is used for the fabrication of the sensing elements and an open‐source prosthetic hand. The strain sensor detects the bending of the fingers and the temperature sensor detects the temperature when in contact with a heated surface, successfully. In addition, the temperature sensor is used as a tactile sensor to detect contact with a non‐heated surface. Combining selective multisensory capabilities will significantly affect the future development of sensorized prosthetic devices and wearable electronics.
Fast Polysulfide Conversion Catalysis and Reversible Anode Operation by A Single Cathode Modifier in Li‐Metal Anode‐Free Lithium‐Sulfur Batteries
Authors: Zhao Yun , Huang Limin , Zhao Dan , Yang Lee Jim
Published: July 2023

The two major issues confronting the commercialization of rechargeable lithium‐sulfur (Li−S) batteries are the sluggish kinetics of the sulfur electrochemical reactions on the cathode and inadequate lithium deposition/stripping reversibility on the anode. They are commonly mitigated with additives designed specifically for the anode and the cathode individually. Here, we report the use of a single cathode modifier, In2Se3, which can effectively catalyse the polysulfide reactions on the cathode, and also improve the reversibility of Li deposition and removal on the anode through a LiInS2/LiInSe2 containing solid electrolyte interface formed in situ by the Se and In ions dissolved in the electrolyte. The amounts of dissolved Se and In are small relative to the amount of In2Se3 administered. The benefits of using this single modification approach were verified in Li‐metal anode‐free Li−S batteries with a Li2S loading of 4 mg cm−2 and a low electrolyte/Li2S ratio of 7.5 μL mg−1. The resulting battery showed 60 % capacity retention after 160 cycles at the 0.2 C rate and an average Coulombic efficiency of 98.27 %, comparing very well with recent studies using separate electrode modifiers.
