A review on strengthening mechanisms of carbon quantum dots-reinforced Cu-matrix nanocomposites
Authors: Xie Yuting , Hu Junyi , Hu Yuxin , Jiang Xiaosong 
Published: July 2024

Abstract
Combination of metal matrix materials with carbon quantum dots (CQDs) can not only optimize the property of metal matrix materials, but also produce novel material systems with ultra-high performance or superior comprehensive performance. The excellent electrical, mechanical, and thermal characteristics of CQDs can compensate for some intrinsic defects of the metal matrices to improve the composite properties. The various interfaces formed through the different degrees of CQDs dispersion in the metal matrices are essential in the mechanism of the composite performance improvement. In this review, the research progress and results of CQDs in metal matrix composites are discussed and summarized, including the recent preparation methods of CQDs and carbon nanostructure-reinforced metal matrix materials, as well as the influences of the preparation methods on the material structures and properties. In addition, by focusing on the interfaces between CQDs and metal matrices in composite materials, the performance improvement and reinforcement mechanisms of the CQD-modified metal matrix composites are described from mechanical, electrical, and thermal aspects. Further studies on CQDs in metal matrix composites are still required to provide theoretical guidance for the preparation of CQDs-reinforced metal matrix composites with intensity and ductility above the average.

Abstract
In last decades, there have been drastic environmental transformations and mutations happening all around the world. Due to the continuous mass transfer process, for example,

CO

{{\rm{CO}}}_{2}

mass transfer, which in this case, takes the form of greenhouse gas emissions, unusual and extreme kinds of phenomena have been occurring here and there, disturbing our ecosystems and causing damage and chaos on their paths. Reducing or stopping these gas emissions has become one of the major topics in our planet. We investigate the solvability of a mathematical model describing the mass transport process in nature and where additional perturbations parameters have been considered. Besides addressing the stability of the model, its convergence analysis is also given with the use of Crank–Nicholson numerical method, in order to assess its efficiency and perform some numerical simulations. The results obtained show that the model’s dynamic is characterized by many grouping (accumulation) zones, where mass (of

AbstractAnxiety is a common issue among university students, many of them experience anxiety, depression, and stress during their school life. This study aimed to compare the acute physiological stress responses of students divided into two groups according to their perceived anxiety levels (positive test anxiety, PTA+, and negative test anxiety, PTA-). Heart rate variability (HRV) and electrodermal activity (EDA) were used to assess stress.Thirty-one healthy volunteers participated in the study. Participants completed anxiety assessments, including the Westside Test Anxiety Scale (WTAS), the State-Trait Anxiety Inventory (STAI), and the Test State Anxiety Inventory (TSAI). Based on their scores, participants were categorized into PTA+ and PTA- groups. All participants underwent 24-h continuous recordings of pulse and electrodermal activity (EDA) on two separate occasions: one day prior to a written exam and during a designated exam-free day serving as a baseline control.We compared the HRV and EDA data obtained on a regular day and on an exam day between the two groups. Results showed that the PTA+ group had significantly higher heart rate, stress index, low frequency, and short-term detrended fluctuation analysis (DFAα1) on the exam day. The tonic EDA component was also higher in the PTA+ group. Stress-related HRV and EDA parameters were negatively correlated with exam scores.In conclusion, the study found that physiological stress indicators obtained from HRV and EDA are associated with perceived exam anxiety in students.

La labor terapéutica: entre las narrativas y la intimidad
Authors: Osorio Sánchez Yeny Leydy 
Published: July 2024

Este ensayo presenta la narratividad como una construcción de la propia historia personal, y como una manera de construir, reconstruir y entregar la historia personal durante el proceso psicoterapéutico. Por otro lado, se aborda el concepto de intimidad, desde la propuesta teórica de José Luis Pardo, para proponer que no sólo se trabaja con las narrativas de la propia existencia, sino, además, con lo que escapa a ellas, con lo que no es alcanzado por la palabra, con lo íntimo. El abordaje de la intimidad es uno de los fundamentos del trabajo terapéutico.

Authors: Miklašēvičs Ziedonis 
Published: July 2024

Although Pinus sylvestris has a wide distribution throughout Europe, there are lack of scientifically approved information related to the sapwood timber strength parameters impregnated with natural resins comparing to the strenth parameters of non-resinous wood and industrially impregnated roundwood assortments using as the elements of wooden constructions such as wood poles for power lines. The main goal of the study is to work out the Pinus sylvestris stems which were previously treated using resin tapping technologies and harvested in final felling sites, timber strength parameters depending on timber quality characterized data based on the testing methods: moisture content - according to ISO13061-1:2014; density - according to ISO13061-2:2014; compression strength paralel to the grain- according to ISO 13061-17:2017; modulus of elasticity- according to ISO 13061- 4:2014; three point bending strength - according to ISO 13061- 3:2014. The results of the study might help for practical applications so that this wood specie can be processed more efficiently for the value - added products whose timber quality indicators would allow it to be used in wooden structures without additional chemical and thermal treatment, to establish more accurate quality requirements for roundwood assortments and to provide useful information for optimizing Scots pine harvesting management programs.

Authors: Snipkis Andrejs , Semjonova Guna , Smite Daina 
Published: July 2024

Research focus and aim: To investigate the usability and utility of the SnipTouch innovative agility training device prototype in patients with upper extremity impairments after stroke. Research methods used: The study of several case studies was selected by formulating the research phenomenon and proposing two units of analysis- 1) usability and 2) utility of innovative prototype device SnipTouch. The multiple case study involved 7 stroke survivors with impaired upper limb functions who participated in eight physiotherapy sessions adding the SnipTouch intervention. The device operates on a dexterity training principle, where the main task is to quickly touch a lit button. Participants underwent pre-intervention upper extremity assessments using ROM, MMT, NRS, MAS, FMA-UE, 9HPT, BBT, and RTT. After the eighth session of physical therapy, reassessments were conducted with the same tools, supplemented by semi-structured interviews and usability evaluations using UEQ and SUS. The collected data were compiled and analysed using established data analysis methods. Results: Five participants assessed the usability of the equipment in the SUS questionnaire as outstanding (from 87,5 to 97,5 points), one participant as excellent (82,5 points) and one very good (77,5 points). The UEQ on six scales resulted in the following device evaluation: attractiveness 2.6, perspicuity 2.79, efficiency 2.32, dependability 2.14, stimulation 2.64, novelty 2.43. The UEQ benchmark classifies the innovative prototype device SnipTouch into Excellent category. The results of the upper limb functional tests show improvements in all participants. The main Conclusions and Recommendations: The results of the study demonstrate that the SnipTouch innovative device prototype is usable and the overlap of qualitative and quantitative data confirmed the utility of the device in improving reaction time, range of motion, agility, movement coordination, muscle strength, in addition to conventional rehabilitation therapy methods for stroke patients.
Ground-Motion Modeling of the 2016 Mw 6.2 Amatrice, Italy, Earthquake, by a Broadband Hybrid Kinematic Approach, Including Empirical Site Effects

Published: July 2024

Abstract
The region of Central Italy is well known for its moderate to large earthquakes. Events such as the 2016 Mw 6.2 Amatrice earthquake generated in the shallow extensional tectonic regime motivate numerical simulations to gain insights into source-related ground-motion complexities in the near-source region. We utilize a hybrid integral-composite kinematic rupture model by Gallovič and Brokešová (2007) to simulate the Amatrice earthquake in a broadband frequency range (up to 10 Hz). In the first step, we optimize the input source parameters using a grid-search method by minimizing the spectral acceleration bias between synthetic and recorded strong-motion data at reference rock stations within 50 km of the source. To verify the robustness of the optimal model, we simulate the ground motions at 400 virtual stations and compare their spectral accelerations with the predictions of an empirical nonergodic ground-motion model (GMM) for rock sites in Central Italy (Sgobba et al., 2021). The synthetics show a good agreement with the empirical model regarding both median and variability. Finally, we account for local site effects at nonreference stations by combining the simulations on rock with empirical site terms derived by the nonergodic GMM. The site-corrected spectral responses generally improve the match with the observations, demonstrating a successful fusion of numerical simulations with empirical estimates toward reproducing near-source ground motions.
The Relationship of Flat Foot to Agility in Children Aged 7-10 Years
Authors: Sidarta Nuryani , Afyora Ririn 
Published: July 2024

Background
Lower extremity deformity could cause changes in the anatomical structure of the body, one of which was a flat foot. It was stated that 90% of the clinic visits for foot problems were related to flat foot. Studies still showed controversy regarding the relationship between flat foot and agility especially in children. This study aims to see the relationship between the incidence of flat foot and the level of agility in children aged 7 to 10 years.
Methods
A cross-sectional study was conducted on children aged 7-10 years who attend primary school in Jakarta. Sampling used simple random sampling with inclusion criteria for research subjects who had a normal BMI, were cooperative, and were willing to take part in the study. Exclusion criteria included children with special needs, children with pain or a history of lower extremity injuries, those having a cavus foot, and children in unhealthy conditions. The research was carried out from February to April 2023. Assessment of flat feet used the wet footprint test and shuttle run test was being used to measure the children’s agility. Bivariate data analysis used the Chi-square test with a significance level of p <0.05.
Results
As 168 respondents were studied, it was found that 58.3% had flat feet. Measurement of agility with the shuttle run test results in 51.8% of respondents who have below-average agility. The results of the Chi-Square test showed that there was a significant relationship between flat feet and agility (p<0.05).
Conclusions
There is a relationship between flat foot and agility in children aged 7-10 years.

Costs of attaining larger size prior to migration inferred from predation-caused wounds in an anadromous fish

Published: July 2024

Abstract

Survival during migration typically depends on body size, in which smaller migrants suffer higher mortality. Thus, migratory animals are predicted to adopt growth tactics to attain large size before migration. Size-dependent growth patterns represent such a case, in which smaller migrants exhibit rapid growth and delay start of migration (extended pre-migration period) to attain a large body size to survive migration. To evaluate adaptiveness of such size-dependent growth patterns, it is crucial to understand costs associated with rapid growth and delayed migration start, since the adaptiveness of the size-dependent growth patterns cannot be solely explained by ecological demands of rapid growth and late migration start. However, potential costs remain largely unknown. Here, we focused on the trade-off between growth and survival, and investigated whether faster pre-migration growth rates and longer pre-migration periods incurred higher predation risk in masu salmon (Oncorhynchus masou), which exhibit size-dependent growth patterns. In a capture-mark-recapture survey examining predation-caused wounds as a proxy for predation risk, we found a non-significant effect of growth rate but a significantly positive effect of timing of migration initiation on the frequency of predation-caused wounds. In particular, migrants that stayed longer in the river had higher probabilities of having predation-caused wounds, especially inflicted by piscivorous birds. This implies that smaller migrants extend their stay in the river to attain larger size for surviving oceanic migration, although the extended stay in the river is costly in terms of increased predation risk.

Abstract

Background
The threat from Dengue Fever (DF) is fast becoming a global menace. The burden of DF in Oyo State and indeed in Nigeria remains unclear, as cases go underdiagnosed or misdiagnosed as malaria. This is attributable to poor health-seeking behavior of the population, weak surveillance systems, and poor health infrastructure. Consistent surveillance of this pathogen using a one-health approach is necessary to assess the public health impact, meteorological influence, vectoral abundance, high-risk groups, and locations associated with Dengue Virus (DENV) infections.
Methods
A cross-sectional study was conducted from Jan 2022 to April 2023. It involved screening DENV in 289 human blood samples and 1,015 Aedes species mosquitoes. Viral RNA was extracted and purified using Jena Bioscience Viral DNA + RNA purification kit. These were analyzed using the One-Step PrimeScript III RT-qPCR mix. Serological detection of DENV-specific antibodies IgM and IgG in humans was analyzed using a one-step lateral flow immunoassay cassette test kit. Patients who were DENV IgM positive were screened for Lassa Virus (LASV) to rule out coinfection. Adult Aedes mosquitoes were trapped using Biogents Sentinel Trap. Mosquitoes recovered were morphologically identified and classified using appropriate taxonomical keys. Meteorological data was obtained from NIMET. Data was abridged as proportions; correlation analysis was done to determine associations.
Result
The overall seroprevalence of DENV was 128/289 (44.2%) with 19/289 (6.6%) and 109/289 (37.7%) being IgM and IgG positive. DENV was detected all year round with more cases in the rainy season. LASV and DENV coinfection was detected in a participant. DENV RT-qPCR analysis in febrile patients and mosquitoes was negative. There was a high abundance of Aedes aegypti (79.5%) in all the locations surveyed with Aedes albopictus (12.3%) detected in Ido LGA and Ibadan South-East LGA while Aedes simpsoni (9.1%) was found at Iwajowa LGA. Mosquito populations varied during the study period in response to prevailing weather conditions.
Conclusion
The high seroprevalence in this study demonstrates an ongoing transmission and exposure to DENV in Oyo State, this further underscores the need to include DF as a differential diagnosis for febrile illnesses. Surveillance system strengthening, as well as timely, accessible, and sensitive laboratory diagnosis for DF, is advocated.
Estimation of the AC electrical properties of some clay ceramic samples under different compositions and firing temperatures
Authors: Gomaa Mohamed Mahmoud , Mohamed Ahmed 
Published: July 2024

Abstract

Raw materials for ceramics made of clay are completely functional. Ceramic-floor tiles are made using clays combined with homogenous batches. Mineralogical, electrical, and ceramic properties were tested. Electrical properties are influenced by firing temperature and chemical composition. At room temperature, samples of natural crude clay were electronically monitored both before and after fire. The measurements (chemical composition, main and minor chemical features, petrography, X-ray, SEM, electrical properties, and chemical composition) demonstrate how firing temperature and chemical composition (from clay to ceramic) impact mixture behavior and how clay-ceramic products can be enhanced. Dielectric constant and conductivity both rise with temperature. Humidity affects electrical properties as well. Charges from ore minerals improve electrical properties. Diffusion polarization, excess ion exchange, and surface charge displacement control grains. This study enhances the commercial use of ceramic clay mineral samples by demonstrating how composition and temperature affect the samples' electrical properties.
