Published: December 2023

A síndrome braquicefálica cursa com alterações obstrutivas de trato respiratório anterior que desencadeiam sinais clínicos como dispneia inspiratória, ronco e síncope, diminuindo a qualidade de vida desses animais. O diagnóstico é baseado no exame físico, sinais clínicos presentes associado a exames de imagem. O tratamento de eleição é a correção cirúrgica das anomalias obstrutivas. A obesidade é um fator de risco para a síndrome braquicefálica, pois aumenta o tecido adiposo nas vias aéreas, estreitando o lúmen e piorando o esforço respiratório. O escore de condição corporal é um método subjetivo e semiquantitativo que avalia a gordura corporal. Em função da redução da qualidade de vida e do potencial risco de óbito, é de extrema importância estudar os impactos da obesidade, idade, estado reprodutivo, sexo e raça na gravidade dos sinais clínicos destes animais. Com isso, realizou-se um estudo retrospectivo baseado no prontuário de cães portadores da síndrome braquicefálica atendidos no município do Rio de Janeiro, em um serviço veterinário especializado em alterações respiratórias de pequenos animais. Foi demonstrado existir associação entre a raça, escore de condição corporal e o avançar da idade com o aumento do grau de manifestações clínicas. Não foi constatada associação da gravidade dos sinais clínicos com o sexo e o estado reprodutivo. Diante disso, é de extrema importância a conscientização dos veterinários e responsáveis sobre a manutenção de um adequado escore de condição corporal e indicação precoce do tratamento cirúrgico das anomalias obstrutivas para melhor qualidade de vida desses animais.

Published: December 2023

Supply chain management encompasses the study of efficiency and effectiveness in material, information, and monetary flow within the industrial sector. Assessing performance is pivotal in gauging a company's managerial capacities. At PT Otsuka Indonesia, research was undertaken during an internship, involving observations and interviews. Subsequently, Key Performance Indicators (KPIs) were formulated, covering aspects such as accuracy in raw material usage, precision in production level planning, frequency of production plan changes, source cycle time, finished product quality, make cycle time, delivery cycle time, precision in avoiding delays in finished goods delivery, and return of finished goods. Snorm de Boer normalization was applied to calculate the KPIs, generating performance results for each indicator. Determining the ultimate performance involved weighting via the Analytical Hierarchy Process (AHP) method, assigning significance levels to each KPI. Post data processing, it was evident that the finished product quality indicator had the lowest value. Consequently, improvement proposals were designed using the Failure Mode and Effects Analysis (FMEA) method. These proposals culminated in the development of warning sticker designs for machine cleaning, comprehensive Personal Protective Equipment (PPE) usage, and scales rechecking.
THE EFFECT OF ESCHERICHIA COLI BACTERIOPHAGE COCKTAIL ON BACTERIAL CONTAMINATION IN WATER
Authors: EROL Hilal Basak , KESKİN Aylin
Published: December 2023

Objective: Wastewater and environmental water resources are treated to eliminate pathogenic microorganisms but contamination is still a significant problem. In particular, the presence of contamination with Escherichia coli (E. coli) is an important indicator of fecal contamination. Due to increasing antimicrobial resistance and failures of new antimicrobial processes, interest in bacteriophages in pathogen control has increased. Therefore, in our study, phage-based bacteria control in environmental waters was investigated as a natural solution.
Material and Method: In our study, E. coli and lytic bacteriophages specific to these E. coli were isolated from environmental water samples in Ankara. The lytic activities of the isolated phages were determined on environmental and clinical extended-spectrum β-lactamases E. coli isolates. Three phages with high lytic activity were selected, and the effectiveness of the single phage and their mixtures on E. coli contamination in water was tested.
Result and Discussion: As a result of the study, 17 E. coli strains were isolated from 30 environmental water samples. Lytic bacteriophages in 30 different plaque structures were also isolated from water samples. The isolated phages were found to have lytic activity in the range of 32-70% on the tested bacteria. The effectiveness of three selected phages and their cocktail on E. coli contamination in water was measured at 6th and 24th. As a result, it was observed that the cocktail application reduced the number of host bacteria in the water below detectable limits, also provided a 5-log reduction in non-host test bacteria and maintained its effect for 24 hours. When the results are evaluated, it is thought that cocktail phage application will be an effective method against E. coli contamination in water.

Published: December 2023

Single-crystal superalloys have been popularly employed in high-temperature parts of gas turbines, such as blades. However, the welds of such alloys are highly susceptible to solidification cracking, which limits their applicability to high-temperature turbine blades. In this study, the effects of characteristics of weld solidification on solidification cracking susceptibilities (solidification brittle temperature range, BTR) were fundamentally investigated for the CMSX-4 single-crystal superalloy. We applied a transverse-Varestraint test procedure for both the linear and oscillated arc welds by changing the weld solidification characteristics, such as the degree of single crystal growth and formation of solidification grain boundaries. The BTR for the CMSX-4 alloy is 336 K for linear welding condition, whereas the values are 434 K and 342 K for 0.6 and 1.5 Hz oscillated welds. Interestingly, the BTR continuously increases with the weld oscillation frequency. By contrast, almost no changes in the weld mushy-zone temperature range are theoretically calculated for each welding condition via the diffusion-controlled Scheil model. The mechanism underlying the increase in BTR under oscillation welding is clarified based on the relationship between the achievement ratio of the weld single crystal growth and fraction of high-angle (>15o) solidification boundaries, which affect severe dendrite coalescence undercooling. The lower fraction of the high-angle weld solidification grain boundaries attributed to the superior achievement ratio of weld single crystal growth, which reduces the dendrite coalescence undercooling and BTR. Consequently, it enhances the solidification crack propagation resistance.

Published: December 2023

Here, we investigated the influence of δ-precipitate (orthorhombic D0a Ni3Nb-ordered phase) on the room- and high-temperature tensile properties in wrought nickel-based Inconel 625 superalloys subjected to solution and aging heat treatment. Typically, solution heat-treatment temperatures in these alloys affect the solid-state precipitation of δ-phase, which governs high-temperature tensile properties. While precipitation of fine D0a δ-phase is known to have beneficial effects on the mechanical properties owing to the retardation of grain coarsening, Widmanstätten δ precipitation plays a deleterious influence on the fracture toughness, tensile ductility, and fatigue resistance. Therefore, to enhance the mechanical properties of this alloy series, it is key to generate a high number density of fine D0a δ precipitate by adjusting solid solution treatment temperatures. In this study, solution heat treatments were conducted above and below δ-phase solvus temperatures. By applying solution heat treatment at 900°C and 970°C, this alloy was confirmed to have a Widmanstätten δ phase and is composed similarly to the annealed microstructure. This Widmanstätten δ precipitate was densely distributed at both intergranular and intragranular grains. On the other hand, when solution treatment was applied at 1040 and 1100°C, more coarse particles (approximately 30 μm) with a significant reduction of Widmanstätten type δ phase were obtained. We found that grain size and Widmanstätten δ-phases have an important role in the high-temperature tensile properties of Inconel 625 superalloy series.

Published: December 2023

Carbon fiber reinforced polymer (CFRP) has been extensively used in civil engineering for applications such as reinforcing and retrofitting various architectural materials. Therefore, understanding the degradation of CFRP under high temperatures is important. This study aims to investigate the thermomechanical and microstructural properties of CFRP plates at elevated temperatures up to 350 oC. The platetype CFRP composites were subjected to temperatures of 50, 100, 150, 200, 250, 300, and 350 oC, and then compared with pristine CFRP samples. X-ray diffraction analysis was conducted to examine the crystal structures of the carbon fibers and epoxy resin matrices in the CFRP. At temperatures higher than 150 oC, the FWHM increased due to the degradation and softening of the resin matrix. Delamination and debonding between the matrix and fibers were observed in samples exposed to temperatures above 200 oC. The maximum tensile strength of the CFRP plates exposed at 350 oC significantly decreased to 0.605 GPa, a reduction of approximately 40% compared to the pristine sample. On the other hand, Young's modulus remained relatively unchanged across the different temperatures. This suggests that the polymer matrix degradation plays a crucial role in the mechanical properties of CFRP, as the matrix layers contribute significantly to the distribution of forces.
Material Selection: Material Perception Data Analysis Using Clustering Analysis and Association Rule Analysis of Data Mining
Authors: Choi Jaeho
Published: December 2023

To select materials suitable for products, material perception, which is the feeling consumers have about materials, has been studied. Material perception data were obtained through surveys using digital logic for bipolar adjective pairs. The material perception data were analyzed through unsupervised learning of data mining. Prior to data analysis, to increase the reliability of the data, the homogeneity of the data between surveys was tested using clustering analysis, correlation analysis and chi-squared test. After checking the homogeneity of the data between surveys, the data were merged. The merged material perception data were analyzed using relative frequencies, hierarchical clustering, and association rules. The relative frequencies obtained from survey participants' selections were used to determine the prevailing perceptions of each material and as basic data for other analyses. In the hierarchical clustering analysis, hierarchy was identified using distances within clusters and distances between clusters. Through association rule analysis, the consumer's simultaneous perceptions of the material can be known, so not only the individual characteristics of the material but also the relational characteristics can be considered when selecting materials based on consumer's perception. The analyzed characteristics were designed into a material perception map, and this material perception map will be a powerful tool to help product designers make better choices that match consumers' perception and experience when selecting materials.
“MALLAPPESSANG OLOK-KOLOK”: PERJUMPAAN ISLAM DAN TRADISI LOKAL DALAM MEMORI KOLEKTIF MASYARAKAT BUGIS
Authors: Subair Muh , Rusli Rismawidiawati , Kila Syahrir
Published: December 2023

This article presents the findings of a qualitative research study that delves into the collective memory of the Bugis community concerning the intersection of Islam and local traditions. Collecting data through observation, interviews, and document analysis, this study shows that the Mallappessang olok-kolok (Releasing animals) tradition has sparked controversy in the community. The study analyzed the oral storytelling-based community’s tradition narratively. Mallappessang olok-kolok constitutes a “tolok bala” tradition, a local ritual designed for averting disasters. The Bugis society practices it by releasing animals into the forest to hope for healing from an illness. Some view the practice as contrary to Islam’s continuity from animism and dynamism and its implementation as unreasonable. On the other hand, others consider the tradition adheres to Islamic teachings. Releasing animals into the forest to feed wild animals expresses human harmony with nature. The act is also viewed as bonding with ancestors, following ancestral guidelines, and fostering community unity as families, relatives, and neighbors actively participate in the ritual. The narrative of this different perspective then rolls into a discussion or dialogue between Islam and local culture, which then impacts the existence of respect for the presence of these traditions. The conversation between Islam and local culture is a sign of progress in the thought of Islamic society that accepts traditions as heritage and science impacting on strengthening human relations with nature.
THE IMPACTS OF CORPORATE GOVERNANCE MECHANISMS AND OWNERSHIP STRUCTURE ON CAPITAL STRUCTURE OF CHINESE DUAL-LISTED COMPANIES
Authors: Wing Kwong, Chan  , Ei Yet, Chu
Published: December 2023

This research aims to assess how the mechanisms of corporate governance and ownership structure affect the capital structures of Chinese dual-listed companies that list their shares in the China A-share market and the Hong Kong market simultaneously from 2003 to 2019. A binary variable of state control firm attribute is introduced to proxy the political connection to the Chinese government. Both the independent director ratio and CEO duality are negatively and significantly associated with the long-term debt ratio. The board size negatively and significantly relates to the short-term debt ratio. Evidence of board members’ avoidance of investors’ pressure to use more debt and escape from debt lenders’ monitoring is observed in this research. Both foreign ownership and state ownership are significantly and negatively associate with the short-term debt ratio, but significantly and positively associate with the long-term debt ratio. Thus, both foreign investors and the Chinese government prefer the companies to achieve rapid growth through the use of more long-term debts. The binary variable of state control firm attribute has a significant positive association with the short-term debt ratio alone. However, evidence of declining use of long-term debt financing due to political connections, such as the issuance of equity, is not observed.

Published: December 2023

The average Malaysian disposes of 15,000 tonnes of food waste per day, out of which 6,000 tonnes is avoidable waste that could feed the poor. This study aims to address food security issues (SDG 2) in Malaysia by using Bandura’s Triadic Model of Reciprocal Determination to examine food wastage behaviours among urban post-millennials. Food waste, which comprises spoilage, preparation waste, and plate waste, is common in schools; as such, qualitative interviews were conducted with 25 urban primary school students in Klang Valley, Malaysia. The findings revealed the interplay between students' personal factors, physical environment factors, and social environment factors in influencing their food wastage behaviours and perspectives. Additionally, it was observed that behavioural changes towards zero-food waste within the school community require environmental interventions, as urban school-goers lack knowledge of food storage alternatives, while their surrounding environment does not support broader food security concerns. Based on the findings, this study proposed a modified triadic model which incorporates permaculture as a sustainable practice in urban schools in Malaysia. Permaculture can act as an environmental stimulus that cultivates students’ positive personal attitudes and feelings towards reducing food waste. Subsequently, there would be a reduction in food waste behaviour within the students' existing ecosystem. This study promotes the reduction of food waste in urban schools and contributes towards formulating a framework for food security in schools.

Published: December 2023

The surge of online food delivery (OFD) services is emblematic of the restaurant industry's presence in the e-delivery landscape. Further, this research reveals that comprehending consumer decision-making processes necessitates the appraisal of consumer behavior perception. Thus, this study aims to scrutinize the impact of hedonic motivation, convenience motivation, and post-usage usefulness on consumer interest and behavior towards OFD services, moderated by their attitudes towards using such services. To achieve this objective, a purposive sample of 150 students who have used OFD services was gathered and analyzed using a quantitative approach. Empirical data was collected via questionnaires, and a structural equation modeling (SEM-AMOS) was employed to examine the empirical model. The findings of this study suggest that hedonic motivation, convenience motivation, post-usage usefulness, and attitudes towards OFD were key determinants of OFD service behavioral intention. The swift expansion of fast food in Indonesia can be attributed to advancements in telecommunication infrastructure and internet users, lower smartphone prices, as well as the convenience and accessibility of mobile phones and the internet. This phenomenon has been capitalized on by fast food companies, who have leveraged online food delivery (OFD) services to cater to the surging demand.

Authors: Zhao Wanjin , Sun Weitao , Gao Jianhu , He Run
Published: December 2023

The wave characteristics of fractured-porous media can be utilized for permeability identification; however, further research is necessary to enhance the accuracy of this identification. A novel wave equation for fractured-porous media is formulated, and theoretical analysis suggests its effectiveness in accurately identifying reservoir permeability. The proposed methodology establishes a wave equation for fractured-porous media using the volume averaging method and employs finite difference method on staggered grids to calculate wave field dispersion and attenuation, exploring the influence of fracture network structure and confining pressure on the solution of the wave equation. By analyzing the wave equation under various aspect ratios and confining pressure of fractures, it is observed that these factors significantly affect velocity and attenuation, providing valuable insights into seismic response in fractured-porous media. Furthermore, the research findings reveal promising potential in utilizing the new wave equations specific to fractured-porous media for permeability identification purposes. By constructing a three-dimensional fractured-porous network model, the wave equation for permeability identification can examine the correlation between the parameters of the equation and permeability, and establishes an association between fracture parameters and permeability, paving the way for a novel approach to permeability identification.

This paper has developed a comprehensive visual experimental system that is specifically tailored to simulate diverse coal body conditions, ground stress and gas pressures. By monitoring and analyzing the real-time progression of coal fissures during the outburst process, we can obtain valuable insights into the evolution and mechanisms of coal and gas outbursts. Additionally, this study introduces a method to determine the critical threshold for predicting coal and gas outbursts, and the critical gas pressure threshold for Jiulishan Coal Mine (Jiaozuo City, Henan Province, China) is established at 0.6 MPa.
Detailed crustal deformation in the Ailaoshan Orogenic Belt revealed by receiver functions from a dense array
Authors: Wu Chenglong , Xu Tao , Bai Zhiming
Published: December 2023

The Ailaoshan Orogenic Belt (AOB), located at the southeastern boundary of the Tibetan Plateau, is an ideal place for investigating the mechanisms of lateral growth of Tibet. Using the data recorded by a dense seismic array across the Ailaoshan belt, we investigate the detailed lateral variations of crustal anisotropy on the basis of Pms phase of receiver functions. Remarkable crustal anisotropy is observed throughout this study region with a mean delay time of 0.33 ± 0.19 s, indicating the anisotropy primarily originates in the middle-lower crust. The fast directions beneath the AOB including the Ailaoshan-Red River shear zone (ARRSZ) and its western low-grade metamorphic unit generally align with the NW-SE strike of ARRSZ. The weak anisotropy in the South China Block (SCB) argues that the block is relatively stable, with limited internal deformation. Meanwhile, the anisotropy beneath the western boundary of the SCB is strong, and the N-S oriented fast direction is influenced by both the crustal stress and Xiaojiang Fault. Combining the high Vp/Vs and significant lateral variations of crustal anisotropy parameters, we suggest that the strike-slip motion along the ARRSZ induces the partial melting and pronounced anisotropy in the middle-lower crust of AOB, without the presence of crustal flow. The differences between crustal and mantle anisotropy indicate crust-mantle decoupling deformation of the AOB, supporting the block extrusion model occurring only in the crustal scale as the primary deformation pattern.

Published: December 2023

Introduction: Distributed power supply has increasingly taken over as the energy industry’s primary development direction as a result of the advancement of new energy technology and energy connectivity technology. In order to build isolated island microgrids, such as villages, islands, and remote mountainous places, the distributed power supply design is frequently employed. Due to government subsidies and declining capital costs, the configured capacity of new energy resources like solar and wind energy has been substantially rising in recent years. However, the new energy sources might lead to a number of significant operational problems, including over-voltage and ongoing swings in the price of power. Additionally, the economic advantages availed by electricity consumers may be impacted by the change in electricity costs and the unpredictability of the output power of renewable energy sources.

Methods: This paper proposes a novel framework for enhancing renewable energy management and reducing the investment constraint of energy storage. First, the energy storage incentive is determined through a bi-level game method. Then, the net incentive of each element is maximized by deploying a master–slave approach. Finally, a reward and punishment strategy is employed to optimize the energy storage in the cluster.

Results: Simulation results show that the proposed framework has better performance under different operating conditions.

Discussion: The energy storage operators and numerous energy storage users can implement master–slave game-based energy storage pricing and capacity optimization techniques to help each party make the best choices possible and realize the multi-subject interests of energy storage leasing supply and demand win–win conditions.
The impact of China’s new Environmental Protection Law on corporate environmental investments
Authors: Liu Weiming , Qiu Yating , Jia Lijiang , Wu You , Zhou Qingmei
Published: December 2023

As an important lever for China’s green development strategy, whether the new Environmental Protection Law can effectively form investment incentives for enterprises has attracted much attention and is also an important topic that theoretical research urgently needs to explore. This paper utilizes corporate data from non-financial listed companies in Shanghai and Shenzhen A-shares from 2007 to 2018. By adopting a double-difference model, it explores the incentive role and internal mechanism of the new Environmental Protection Law (EPL), implemented in 2015, as an environmental regulation on the environmental protection investment of enterprises, taking the new EPL’s enactment as a quasi-natural experiment. The study revealed a noteworthy and positive impact on motivation, which remained consistent even after various robustness tests. Additionally, the impact of incentives varied depending on the level of competition within the industry, financial constraints, and ownership type of the enterprises. Investigating the mechanism, it has been discovered that the incentive effect advances the environmental investment of firms through diminishing agency costs, enriching the quality of environmental information disclosure, and facilitating government subsidies to enterprises. This study not only verifies, from the factual empirical level, that environmental regulation policies can promote corporate environmental investment but also provides important evidence to support to a certain extent that the implementation of the new EPL can promote enterprises’ environmental governance behaviors. This article reveals the microeconomic effects of the new Environmental Protection Law from the perspective of corporate behavior strategies, and the research conclusions have important reference significance for the construction of national legal systems and the deepening of green development strategies.

Published: December 2023

To study their feeding habits, Coregonus ussuriensis samples were collected seasonally in the Amur River, China. A total of 574 samples were collected, including 200 individuals with empty stomachs. The stomach contents of the remaining 374 samples were identified, counted, weighed, and analyzed. The results showed that the vacuity rate of Coregonus ussuriensis was 34.84% in total; the rates in summer and autumn were higher than in spring and winter. Prey items could be divided into three categories: fish, benthos, and mammals, with 62 taxonomic units. Of these, fish had the highest relative importance index (IRI), followed by benthos and mammals. Specifically, Exopalaemon modestus was the dominant species among the food species of Coregonus ussuriensis, and unidentified fish, Hydropsyche sp., Hemiculter leucisculus, Abbottina rivularis, and Saurogobio dabryi were important species. The average repletion index (RI, %) of Coregonus ussuriensis was highest in autumn (1.86), followed by winter (1.40), summer (1.26), and spring (1.02). The main food of Coregonus ussuriensis was benthos in spring and autumn, and fish in summer and winter. Cluster analysis showed that, according to the similarity level of the bait biological composition, the fork length group samples of Coregonus ussuriensis could be divided into three groups: 210–330 mm, 330–450 mm, and >450 mm. The highest IRI% of feed organisms in these three groups of samples were fish (73.67%), benthos (75.12%), and benthos (94.46%), respectively. It can be observed that with the growth of the fork length of Coregonus ussuriensis, the importance of benthos in its diet increases. The results of an RDA analysis on the relationship between main bait organisms and various factors indicated that season, river level, river width, and fish size have a significant impact on bait organisms and a positive or negative impact on the quality scores of some bait species. This study filled the gap in biological research on the feeding ecology of Coregonus ussuriensis and laid a research foundation for ecological research on this species and its resource protection and aquaculture.

This paper analyses the influence that different supervisor supportive behaviors have on subordinate job satisfaction, while considering the gender of individuals involved (supervisor and subordinate). The empirical evidence provided by a sample of 29,833 subordinates from 35 European countries collected by Eurofound through the European Working Condition Survey allows us to assert the following. First, subordinate job satisfaction depends on their perceptions about the supportive behaviors provided by their supervisors in terms of respect, giving recognition for a job well done, coordinating work, helping get the job done, and encouraging the professional development of the subordinate. Second, job satisfaction is affected by supervisor gender, although in the opposite direction as hypothesized, such that when the supervisor is a woman, subordinates report lower job satisfaction. Third, also contrary to our expectations, supervisor-subordinate gender similarity reduces, rather than increases, subordinate job satisfaction. Fourth, gender similarity, as expected, weakens the impact of several supervisor supportive behaviors on this job satisfaction (i.e., giving recognition, coordinating work, helping get the job done, and encouraging development). In terms of practical implications, this work suggests that it is advisable for supervisors to show supportive behaviors toward subordinates. In addition, because demonstrating respect at work is not moderated by gender similarity and seems to be the most impactful supportive behavior for enhancing job satisfaction, supervisors should pay particular attention to the respect of subordinates.

A novel trajectory generation and control architecture for fully autonomous autorotative flare that combines rapid path generation with model-based control is proposed. The trajectory generation component uses optical Tau theory to compute flare trajectories for both longitudinal and vertical speed. These flare trajectories are tracked using a nonlinear dynamic inversion (NDI) control law. One convenient feature of NDI is that it inverts the plant model in its feedback linearization loop, which eliminates the need for gain scheduling. However, the plant model used for feedback linearization still needs to be scheduled with the flight condition. This key aspect is leveraged to derive a control law that is scheduled with linearized models of the rotorcraft flight dynamics obtained in steady-state autorotation, while relying on a single set of gains. Computer simulations are used to demonstrate that the NDI control law is able to successfully execute autorotative flare in the UH-60 aircraft. Autonomous flare trajectories are compared to piloted simulation data to assess similarities and discrepancies between piloted and automatic control approaches. Trade studies examine which combinations of downrange distances and altitudes at flare initiation result in successful autorotative landings.

Li-ion batteries (LIBs) represent the most sophisticated electrochemical energy storage technology. Nevertheless, they still suffer from safety issues and practical drawbacks related to the use of toxic and flammable liquid electrolytes. Thus, polymer-based solid electrolytes may be a suitable option to fulfill the safety and energy density requirements, even though the lack of high ionic conductivity at 25 °C (10−8–10−7 S cm−1) hinders their performance. To overcome these drawbacks, herein, we present an all-solid-state Li-metal full cell based on a three-component solid poly(ethylene oxide)/lithium bis(trifluoromethanesulfonyl) imide/titanium dioxide composite electrolyte that outclasses the conventional poly(ethylene oxide)-based solid electrolytes. Moreover, the cell features are enhanced by the combination of the solid electrolyte with a self-standing LiFePO4 catholyte fabricated through an innovative, simple and easily scalable approach. The structural, morphological and compositional properties of this system are characterized, and the results show that the electrochemical performance of the solid composite electrolyte can be considerably improved by tuning the concentration and morphology of TiO2. Additionally, tests performed with the self-standing LiFePO4 catholyte underline a good cyclability of the system, thus confirming the beneficial effects provided by the novel manufacturing path used for the preparation of self-standing electrodes.

Crystalline phase engineering is a prominent strategy for synergistically optimizing the surface–body phases of a catalyst. In this work, TiO2 nanosheets assembled into nanotubes (TNSTs) with two phases, anatase and rutile, were firstly synthesized via crystal engineering by simple thermal annealing. These were subsequently loaded with Ru nanoparticles, with a mean size of 5.0 nm, to create the efficient benzene hydrogenation catalyst Ru/TNSTs. The well-designed nanosheet-tube structure boasts a large specific surface area and excellent transmission channels, which effectively prevents the agglomeration and deactivation of loaded Ru nanoparticles, as well as promoting the internal diffusion in the reaction process of benzene hydrogenation to cyclohexene. Furthermore, titanium dioxide nanosheet-tubes contain numerous Ti3+ defects, which not only improves the overall conversion rate of cyclohexene but also enhances the suppression of cyclohexene adsorption. Most importantly, the titanium dioxide with its two-phase composition of 75 wt% anatase and 25 wt% rutile increases the ratio of electron deficiencies of Ru and promotes cyclohexene desorption. These synergistic properties enhance the selectivity and efficiency of the Ru/TNSTs catalysts, resulting in excellent performance in the hydrogenation of benzene to cyclohexene. In particular, the Ru/TNSTs-4 catalyst (annealed for 4 h), under the specific conditions of 140 °C temperature and 5 MPa hydrogen pressure for the hydrogenation process, achieves a 95% initial selectivity and 51% yield of cyclohexene in the reaction, outperforming most supported Ru-based catalysts. This work may provide new perspectives for designing efficient benzene hydrogenation catalysts via crystalline phase engineering.

Proper nutrition during the first period of life is primarily related to meeting energy needs and providing essential nutrients that ensure the infant’s normal physical and psychomotor development. Improper nutrition during this period, inadequate amounts of nutrients, inappropriate timing and manner of introduction of individual foods, can permanently alter metabolism and the course of physiological processes, increasing the risk of diseases such as obesity, allergic diseases, and cardiovascular diseases. This study aimed to verify how the method of complementary feeding influences the occurrence of food neophobia between 2 and 7 years of age, as well as to assess the different nutritional aspects resulting from the process of starting feeding other than breast milk and milk formula. In this study, 490 mothers and their children aged 2–7 years participated. The research tool was a questionnaire consisting of a child’s dietary assessment and standardized questionnaires assessing food neophobia among children: Food Neophobia Scale for Children (FNSC) and the Montreal Children’s Hospital-Pediatric Feeding (MCH-FS). In the study group of children, 238 (48.57%) had no Baby-Led Weaning Method (no BLW) method used during complementary feeding (CF), and 252 (51.42%) children used Baby-Led Weaning Method (BLW). According to the FNSC questionnaire, a high risk of food neophobia was found in 32.65% of the children studied and a medium risk in 39.80%. The medium risk of feeding problem occured in 11.63% of children, the high risk in 6.73% of children, and the highest risk in 6.94% (MCH-FS). No statistically significant differences were observed between the BLW and NoBLW groups. High risk of food neophobia occured in 1/3 of the children studied, but there was no relationship in the study group between the mode of CF (BLW/NoBLW) and the risk of food neophobia.
