Gry i zabawy ruchowe na lekcjach wychowania fizycznego w edukacji wczesnoszkolnej z uwzględnieniem sytuacji trudnych – kilka przykładów z praktyki
Authors: Wojewoda Anna 
Published: August 2024

Physical education lessons in grades 1-3 of primary school play an important role in the processes of upbringing and socialization. Due to the great need to move and relieve tension at this age, they are a kind of safety valve. During physical education classes, students interact with one another more often. During contact team games or games focused on competition, tensions often occur, personal space is violated, and the child’s emotions take over. This article presents three movement games: a bricklayer, a wolf and seven kids, and piggy in the middle. Authentic difficult situations (such as aggression, escaping from the classroom, throwing objects) that occurred during physical education lessons are described here, and proven solutions based on the teacher’s own experience are presented. The examples provided are not a ready-made recipe for every difficult behavior, but they show how small steps can be calmed down or worked out with the appropriate cooperation of the student, peers, parents, specialists, and the teacher.
Postwar Mourning and Melancholy: Germany Year of Zero and Hiroshima Mon Amour
Authors: Chen Dandan 
Published: August 2024

Abstract
This paper focuses on two films, Germany Year Zero and Hiroshima Mon Amour, which serve as testimonies to the postwar status of Berlin and Hiroshima, offering magnificent topological touches of traumatized cities and profound insights into the intersection of cities and trauma. Through their narratives, these films intricately explore the interplay between the interiorized exterior and the exteriorized interior, the spatialization of the unspeakable, and the folding of memory into the very fabric of cinematic architecture. All these elements are complicatedly intertwined with the themes of melancholy, forgetting, and remembering, adding layers of depth to the cinematic exploration.
Antimicrobial, remineralization, and infiltration: advanced strategies for interrupting dental caries
Authors: Yang Qingyi , Li Fan , Ye Yangyang , Zhang Xu 
Published: August 2024

Abstract
Dental caries, driven by plaque biofilm, poses a major oral health challenge due to imbalance in mineralization and demineralization. The primary objective in caries management is to maintain biofilm homeostasis while facilitating the repair and regeneration of dental hard tissues, thus restoring both structural integrity and functionality of affected teeth. Though antimicrobial and remineralization approaches haven shown promise, their standalone utilization without concurrent bacterial control or rebalancing lacks an integrated strategy to effectively arrest caries progression. Furthermore, according to the principles of minimally invasive dentistry, treatment materials should exhibit high permeability to ensure optimal sealing of demineralized tooth surfaces. The concept of interrupting dental caries (IDC) has emerged as a holistic approach, drawing upon extensive research encompassing three pivotal techniques: antibacterial strategies, remineralization therapies, and infiltration mechanisms, all of which are indispensable components in combating the progression of dental caries. In this review, we provide a comprehensive overview of the mechanisms and applications of antibacterial, remineralization, and infiltration technologies within the context of caries management. Additionally, we summarize advanced materials that align with the IDC concept, aiming to offer valuable insights for designing next-generation materials adept at preventing or halting caries progression efficiently.

Published: August 2024

Abstract
Nanofluids (NFDs) are becoming better understood as a result of substantial boost in thermal efficiency advances and the rate of energy exchange employed in requisite fuel dynamics and automotive coolants. Owing to its usage, computational scrutinization examines the cross-flow of an NFD past an expanding/contracting sheet with the impact of suction. In addition, the entropy and irregular generation/absorption effects are induced to compute/estimate the magnificent point of NFD flow. The innovative components of this study are Brinkman number, nanoparticle volume fraction, dimensionless temperature difference, expanding/contracting factor, irregular heat source/sink, and suction parameters. The boundary layers undergo a stream-wise process through expanding and contracting sheets. Also, the study makes use of numerical simulations to scrutinize the aspects of heat transport and cross-flow of NFDs. The fundamental partial differential equations of the current model are converted to ordinary differential equations by using similarity variables, and then they are exercised via the bvp4c approach. Therefore, parametric research has been used to frame the effects of embedded flow variables on the drag force, heat transfer rate, and entropy generation profiles. Multiple solutions are provided for a certain range of shrinking parameters as well as the mass suction parameter. The results suggest that the shear stress enhances due to suction

Influence of mica paper surface modification on the water resistance of mica paper/organic silicone resin composites
Authors: Wang Haisheng , Ge Heyi , Xu Junke 
Published: August 2024

Abstract
This study enhances the water resistance of mica paper/organic silicone resin composites through surface modification with 3-aminopropyltriethoxysilane (APTES). The Fourier-transform infrared spectroscopy and the X-ray photoelectron spectroscopy confirmed the formation of chemical bonds between APTES and mica. The results showed that at an optimal APTES concentration of 0.6%, the water diffusion coefficient decreased from 5.0 × 10−3 mm²/min to 2.7 × 10−3 mm²/min, and the permeability coefficient decreased from 5.71 × 10−4 mm²/min to 1.94 × 10−4 mm²/min, with a significant reduction in equilibrium water uptake. Additionally, the modified composites exhibited minimal mechanical strength loss after moisture aging, demonstrating excellent water resistance. The interface shear strength tests revealed a 28.6% increase in interfacial bonding strength after APTES modification. This study demonstrates the potential of silane coupling agents to enhance the performance of inorganic polymer composites, providing theoretical support for their industrial application.

Changing Attitudes? Investigating the Link between Couples’ Pandemic Behavior, Cognitive Dissonance, and Gender Role Attitudes in Germany
Authors: Firl Katrin 
Published: August 2024

Abstract
Research found that not only macro-level processes like cohort replacements foster gender role attitude (GRA) change, but also life events and changes in lived realities. Framing the COVID-19 pandemic as a ‘natural experiment’ allows to reduce endogeneity when examining the association between emerging cognitive dissonance and GRA change. Estimating asymmetrical fixed effects regressions, I investigate the influence of changes in the division of family labor on GRAs for respondents with no pre-pandemic attitude-behavior discrepancy, using pairfam waves 11 and 13. Indeed, changes in behavior for respondents who had aligned behaviors and attitudes before the pandemic can be associated with GRA adaptation: A change toward an egalitarian division of family labor during the pandemic can be associated with more egalitarian GRAs. Likewise, a change toward an inegalitarian division can be associated with less egalitarian GRAs. These findings support the usefulness of cognitive dissonance as one explanatory mechanism for intra-individual attitudinal change.

Published: August 2024

Zusammenfassung
Ausgangspunkt unseres Beitrags ist die Beobachtung, dass Eigentumsverhältnisse mit je spezifischen Formen der Weltbeziehung verbunden sind. Um der Frage nachzugehen, ob und wie sich die Weltbeziehungen von Subjekten verändern, wenn Eigentumsverhältnisse in Bewegung geraten, untersuchen wir, ob sich in Praktiken und Erfahrungen des Homesharing Irritationen und Veränderungen der Ding-, Sozial- und Selbstbeziehungen beobachten lassen und welche Form und Richtung diese dabei annehmen. Als Fokus dienen uns die beobachtbaren, stets prekären, tentativen und temporären Vergemeinschaftungsprozesse, die sich beim Teilen des interpersonalen Nahraums ergeben. Auf Grundlage qualitativer Interviews mit Nutzenden von Homesharing-Plattformen zeigen wir, dass die Küche und Situationen des gemeinsamen Essens zentrale Ausgangspunkte für die Gestaltung der Gemeinschaftlichkeit darstellen und rekonstruieren drei Typen von Homesharern, die zwischen den Orientierungen von Professionalität und Familialität oszillieren.
Thermal Deformation Behavior of Bismuth-Containing Stainless Steel

Published: August 2024

Abstract
In the process of thermoplastic processing, bismuth stainless steel is prone to cracking, leading to a high reject rate and even failure in production. To solve this problem and provide a feasible process for the actual production, the true stress–strain curves of the material were obtained by hot compression experiments. Because the thermal simulation system cannot automatically consider the temperature and stress variation of the specimen because of the heat of plastic deformation and the friction between the specimen and the tool, experimental errors were carefully corrected. A kind of exponential function is found to be suitable for describing the modified stress–strain relationship of the invested steel. Based on the dynamic material model and Murty criterion, the thermal processing diagram of the free-cutting austenitic stainless steel was established, and the stable and unstable regions of the hot working of the free-cutting austenitic stainless steel were given. Rolling tests showed that under the condition of the selected stable zone, no crack occurred in the section of the rolled piece. Microscopic analyses showed that the microstructure distribution of rolled parts by the non-instability zone process is relatively uniform, and there were fewer spherical and fusiform inclusions.
Evaluation of Delamination Area of Composite Materials Based on Multiscale Features of Ultrasonic Lamb Waves and Neural Network
Authors: Zhang Penghui , Wu Hui , Ma Shiwei , Huang Kaihua 
Published: August 2024

Abstract
To address the problem of quantitative analysis for delamination damage in composite materials, a method of evaluating delamination area based on Lamb waves multiscale features is proposed. In this method, the Lamb wave scattering signals are collected from composite plate with delamination defects using finite element simulation, and the multiscale feature vectors of time-frequency domain are extracted by using complete ensemble empirical mode decomposition with adaptive noise algorithm. In addition, the delamination area can be evaluated and predicted through a generalized regression neural network by taking advantage of nonlinear mapping capability. The hyperparameters of the neural network are also optimized using genetic algorithm, and the feature vectors calculated at different scales are assigned to the network for training and verification. The results show that the multiscale features of delamination damage are more accurate and stable for the model. The mean value and the mean square deviation of mean absolute percentage error proposed in this study is 13.35 % and 4.35 %, respectively, indicating that the overall performance is better than using single scale features and traditional signal decomposition methods.
Aging-Related Cooling Performance Evaluation and Fabrication Conditions Optimization for Alkane-Based Phase Change Microcapsule-Modified Asphalt
Authors: Tang Yunhong , Wu Chaofan , Wang Xiaodong , Zhang Henglong , Chen Zihao , Yang Xue 
Published: August 2024

Abstract
Phase change microcapsules (PCMCs) have been developed as asphalt binder additives that can lower the peak road temperatures or extend the time it takes to reach the peak temperatures in hot summer times. However, few studies pay much attention to the possible cooling performance decline of PCMC-modified asphalt (PCMA) caused by the degradation of PCMCs during asphalt binder preparation and service processes. In this research, one type of PCMC with a phase change point of 37°C was chosen for the preparation of PCMA. The impact of PCMCs on performance grade, storage stability and cooling effects of PCMA was evaluated. The degradation of PCMCs in asphalt binder after thin-film oven tests and pressure aging vessel (PAV) aging tests was investigated from both perspectives of PCMCs and PCMA. Additionally, the optimal design and preparation conditions for PCMA were discussed based on the cooling efficiency. The results demonstrate that the introduction of PCMCs can endow asphalt with better cooling performance while not causing adverse effects on binder performance grade and storage stability. The results from morphology and enthalpy of PCMCs to rheological behavior and cooling performance of PCMA consistently illustrate the massive damage of PCMCs and cooling performance deterioration of PCMA caused by aging. Increasing the dosage of microcapsules and reducing the binder preparation temperature contribute to the sustainable cooling performance based on orthogonal experiment results.

Abstract
Rock slopes with layered fractured structure are widely distributed in the mountainous areas of Southwest China. Under earthquake, these slopes are highly susceptible to disasters such as collapse, landslides, etc., adversely impacting the operation safety of transportation systems. This study aims to investigate the difference in seismic behaviors of two types of fractured rock slopes with typical dipping and anti-dipping layered structures. To do so, two sets of large-scale shaking table tests on the two typical fractured rock slopes were performed. The emphasis was made on the different failure mechanism of these slopes tested when subjected to four different seismic loadings with step-wise increase in amplitudes up to 0.7 g. We observed a three-stage destabilization process in both cases. For the dipping slope, the initial formation of microcracks and then their rapid development was followed by generation of terraced sliding surface through slope, whereas the formation of microcracks was followed by toppling of rock front until final collapse for the anti-dipping slope. Both slopes exhibit elevation amplification effects upon seismic loads as previously observed in other studies of similar slopes. The acceleration amplification effects near the bedrock interface and within slopes are more significant in the dipping case compared to the anti-dipping one. These effects are much enhanced at the top of slopes considered when the peak input acceleration exceeds 0.4 g. Further, Hilbert marginal spectrum analysis indicates that a sliding failure surface above the midslope was formed for the dipping slope, whereas the anti-dipping slope experienced more severe damages at the slope shoulder. The outcomes of this study are of important potential to assist the risk assessment and early warning of seismic hazards of fractured rock slopes.

What is tomorrow? Cause for most of us tomorrow never came
Tomorrow comes for the news, but it’s the same sad story just a different name
You might not know this word cause tomorrow is a foreign concept when you’re Black
Especially when we lost so many loved ones after saying see you tomorrow, and they never came back
It ain’t no secret that we are under attack
But the crazy part is, it’s by the same system that’s supposed to have our back

Published: August 2024

BACKGROUND
Neonatal hypothermia is a common and preventable cause of neonatal morbidity and mortality. Although hypothermia prevention has been extensively studied in infants &lt;32 weeks’ gestation, the authors of few studies have targeted moderate- and late-preterm infants (MLPIs) in the delivery room.

METHODS
This quality improvement initiative was conducted from June 2019 to June 2023 at the Massachusetts General Hospital NICU and Labor and Delivery Unit. All inborn MLPIs 32 + 0/7 to 36 + 6/7 weeks’ gestation admitted to the NICU were included. We expanded thermoregulatory measures typically used in protocols for infants &lt;32 weeks’ gestation, including increasing delivery room ambient temperature to 74°F and thermal mattress use. The primary outcome was hypothermia (&lt;36.5°C) after NICU admission. The balancing measure was hyperthermia (≥38 °C).

RESULTS
During the study period, there were 566 inborn MLPIs with a mean gestational age of 34 + 3/7 weeks and a mean birth weight of 2269 g. Special cause variation in neonatal hypothermia incidence was observed with a decrease from a mean baseline of 27% to 7.8% postintervention. Special cause variation was observed in hyperthermia incidence, with an increase from 1.4% to 6.2% postintervention largely initially associated with noncompliance with the protocol for thermal mattress removal.

CONCLUSIONS
The expansion of several thermoregulation techniques commonly used in infants &lt;32 weeks’ gestation, particularly thermal mattress use, was associated with a decreased incidence of NICU admission hypothermia in MLPIs, with an increase in mild hyperthermia predominantly associated with concomitant polyethylene wrap use.
