The affinity of bentonite and WO3 nanoparticles toward epoxy resin polymer for radiation shielding
Authors: Elsafi Mohamed , Almuqrin Aljawhara H. , Yasmin Sabina , Sayyed M. I.
Published: April 2023

A thorough comparative analysis was conducted between pure epoxy and a novel epoxy composite that included bentonite and WO3 nanoparticles in varying ratios. This study examined five distinct novel epoxy samples (E00, EB0, EBW1, EBW2, and EBW3) to assess their radiation shielding efficiency (RSE), taking into account the addition of bentonite and WO3 nanoparticles. Furthermore, the study compared the RSE of pure epoxy with that of the novel epoxy composite. To evaluate the radiation shielding ability of the studied epoxy samples, a few radiation shielding parameters such as linear attenuation coefficient (LAC), mass attenuation coefficient (MAC), mean free path (MFP), RSE, and transition factor (I/I
0) were calculated. The RSE values of the epoxy samples were E00 (63.41%), EB0 (87.17%), EBW1 (98.26%), EBW2 (99.82%), and EBW3 (99.99%) at an energy of 0.06 MeV with 4 cm thickness. With the increase in the incident energy, the half-value layer and MFP values were increased, whereas the LAC and MAC values decreased. In conclusion, it can be stated that the sample EBW3 is more suitable among the five epoxy samples studied for attenuating the incident photon energy from 0.06 to 1.33 MeV. Noteworthily, the obtained results demonstrate that the addition of WO3 nanoparticles enhances the shielding ability of epoxy when compared to the addition of the same amount of bentonite.

With the acceleration of power grid modernization, the scale of power grid is expanding. Running operations are becoming increasingly complex. There is a great demand for the analysis and calculation of the operation status of the power grid, line transformation design, fault analysis and treatment, etc. At the same time, with the construction of modern power grids and the continuous development of the power industry, the security problems of power systems have become increasingly prominent. This paper introduced the background of the power data service platform and then conducted academic research and summary on the research and development and design of power data service platform and multidimensional power data service platform. Then it was summarized with the analysis of international journals of emerging power systems. After establishing the algorithm model, the spark platform algorithm framework various algorithms were proposed to provide a theoretical basis for the R&D (research and development) and design of the multidimensional power data service platform. Then it analyzed the factors related to the R&D and design of power data service platform. At the end of the article, the simulation experiment was carried out, and the experiment was summarized and discussed. The experimental results showed that the average value of the neural network on the three criteria is 78.03 %. Therefore, the stability rate, accuracy rate, and recall rate of such algorithms as neural network are excellent in the research and development and design of power data service platform.
Effect of vacancies on the damping attenuation of Mn–Cu–Al–0∼3Sn alloys at room temperature
Authors: Li Xinyou , Guo Yu , Xu Yonggang , Xu Yizhe , Zhang Song , Yang Zhixiong
Published: April 2023

Mn–Cu alloys are metal materials, which can be used to reduce vibration and noise from machines. With their inner damping mechanism, the alloys show an excellent damping capacity. However, previous reports show that the damping capacity of the alloys often attenuates after placing at room temperature (RT) for a long time. In the present study, the as-cast Mn–Cu–Al–0∼3 wt% Sn alloys were held at RT for 18 months. Their crystallization morphology was observed using backscattered electron (BSE) technology. The phase distribution was characterized using electron backscatter diffraction (EBSD). Their phase structure was analyzed by using X-ray diffraction (XRD). Their starting martensite transformation temperature (Ms) and damping capacity were measured by using an inverted torsion pendulum device. It is observed for the first time that the FCT phases mainly form in the dendrites. With vacancies diffusing towards boundaries of phases and twins, the boundaries are pinned and the Ms point declines. Hence, the damping capacity attenuates within 18 months. Moreover, the addition of Sn can weaken the decline trend of Ms point and consequently the IF value of the Sn-contained Mn–Cu alloys attenuates less than that of the none-Sn alloy. This research could help us to understand how to cope with the damping attenuation of the Mn–Cu alloys.
The new

ne: an incipient restandardization process in contemporary Italian
Authors: Miola Emanuele
Published: April 2023

The paper deals with an ongoing change in the clitic paradigm of contemporary Italian, namely the incipient overextension of functions of the clitic ne.

In the standard variety ne can only stand for prepositional phrases consisting of di + [noun phrase] and da + [noun phrase], such as those found in genitival, partitive, and locative constructions or in passive ‘by’-phrases. In contemporary Italian, on the other hand, ne is increasingly appearing as a substitute of a + [noun phrase] when used as the second argument of intransitive bivalent verbs, such as accennare (a) ‘to mention’, appassionarsi
(a) ‘to get passionate (about)’, and sopravvivere (a) ‘to survive’. The latter use has not received much attention in the literature.

This overextension is observed in a number of verbs, drawing on data from four corpora of written and spoken Italian, and is discussed as an incipient change from above, originating in formal registers of Italian and moving downwards into the neo-standard and (albeit rarely) colloquial varieties.

The change seems to have been triggered and favored by the fact that the standard variants for that slot of the paradigm, namely locative vi and ci, are avoided because they are considered too obsolete or low-prestige respectively, and also by the fact that these clitics, when combined with others, especially in pronominal verbs, might be judged agrammatical by some speakers.

Der Cyberspace ist ein ständig wachsendes und modernisiertes Umfeld, das angesichts der Interkonnektivität Chancen für die digitale Transformation bietet. Aus der Integration der physischen Umgebung mit der virtuellen Welt entstehen jedoch auch Herausforderungen, die im Ökosystem der Industrie 4.0 gelöst werden müssen. So führen Konnektivität, Virtualisierung und Digitalisierung sowie Charakteristika des Engineerings (E4.0) zu Herausforderungen in Bezug auf die Cybersicherheit in einem Ökosystem, das Cyber-physische Systeme (CPS) und Digitale Zwillinge (DZ) integriert. Die Verwendung digitaler Geräte durch Konnektivität im Product Lifecycle Management (PLM) kann die Angriffsfläche für Cyber-Attacken erhöhen. Daher soll in diesem Beitrag ein Ansatz für die wichtigsten Cybersicherheitsrisiken vorgestellt werden, die durch die Integration von I4.0-Technologien in Produktionsumgebungen entstehen können. Zudem wird ein spezifischer Fahrplan für die PLM-Cybersicherheit vorgestellt und Beiträge zur Cybersicherheit im DZ erörtert.

Published: April 2023

Disruptive Ereignisse und bahnbrechende Innovationen können Unternehmen im Kern gefährden. Flexibilität und Wandlungsfähigkeit sind in diesen Fällen nicht ausreichend, um adäquat auf extreme äußere Veränderungen reagieren zu können. Unternehmen müssen sich in diesen Fällen über vorgedachte Korridore hinaus verändern und sich somit agil verhalten. Dieser Beitrag macht einen Vorschlag für eine strukturierte Definition des Agilitätsbegriffs aus Sicht der Fabrikplanung. Hierzu werden aus aus Anforderungen der Wertschöpfung jene vier Agilitätsbefähiger abgeleitet, die die Gestaltung agiler Produktionsnetzwerke ermöglichen. Dabei zeigt sich die Konzeptionierung von Standortrollen als geeigneter Lösungsansatz zur Entwicklung resilienter Produktionsnetzwerke.

Published: April 2023

KI-Anwendungen versprechen produzierenden Unternehmen zahlreiche Möglichkeiten zur Effektivitäts- und Effizienzsteigerung. Studien zeigen, dass bislang nur eine Minderheit KI-basierte Assistenzsysteme im eigenen Betrieb einsetzt. Ein Grund liegt darin, dass es den Unternehmen schwerfällt, Potenziale strukturiert zu ermitteln und Risiken realistisch abzuschätzen. Der Beitrag präsentiert einen niederschwelligen und partizipativen Ansatz, mit dem ein potenzieller KI-Anwendungsfall identifiziert, spezifiziert und gemeinsam mit betroffenen Stakeholdern hinsichtlich seiner Nutzenpotenziale bewertet werden kann. Das Vorgehensmodell wurde im Rahmen eines Forschungsprojekts entwickelt und in Zusammenarbeit mit produzierenden Anwendungsunternehmen unterschiedlicher Größe pilothaft umgesetzt.
Paraventricular thalamus dynamically modulates aversive memory via tuning prefrontal inhibitory circuitry
Authors: Wang Tianyu , Yan Rongzhen , Zhang Xinyang , Wang Zongliang , Duan Haoyu , Wang Zeyi , Zhou Qiang
Published: April 2023

The impact of stress on the formation and expression of memory is well-studied, especially on the contributions of stress hormones. But how stress affects brain circuitry dynamically to modulate memory is far less understood. Here, we used male C57BL6/J mice in an auditory fear conditioning as a model system to examine this question and focused on the impact of stress on dorsomedial prefrontal cortex (dmPFC) neurons which play an important role in probabilistic fear memory. We found that paraventricular thalamus (PVT) neurons are robustly activated by acute restraining stress. Elevated PVT activity during probabilistic fear memory expression increases spiking in the dmPFC somatostatin neurons which in turn suppresses spiking of dmPFC parvalbumin (PV) neurons, and reverts the usual low fear responses associated with probabilistic fear memory to high fear. This dynamic and reversible modulation allows the original memory to be preserved and modulated during memory expression. In contrast, elevated PVT activity during fear conditioning impairs synaptic modifications in the dmPFC PV-neurons and abolishes the formation of probabilistic fear memory. Thus, PVT functions as a stress sensor to modulate the formation and expression of aversive memory by tuning inhibitory functions in the prefrontal circuitry.

Significance Statement:

The impact of stress on cognitive functions, such as memory and executive functions, are well-documented especially on the impact by stress hormone. However, the contributions of brain circuitry are far less understood. Here we show that a circuitry-based mechanism can dynamically modulate memory formation and expression, namely, higher stress-induced activity in paraventricular thalamus impairs the formation and expression of probabilistic fear memory by elevating the activity of somatostatin-neurons to suppress spiking in dorsomedial prefrontal parvalbumin neurons. This stress impact on memory via dynamic tuning of prefrontal inhibition preserves the formed memory but enables a dynamic expression of memory. These findings have implications for better stress coping strategies as well as treatment options including better drug targets/mechanisms.

Strategic competition: Toward a genuine step-change for Europe’s defense industry?
Authors: Fiott Daniel
Published: April 2023

Since 2016 the European Union has embarked on a step-change in the way it financially supports and incentivizes defense-industrial cooperation. The year 2022 will go down as another important moment in this process with the EU announcing a series of measures, such as joint defense procurement and joint planning and programming. Russia’s war on Ukraine has only underlined the importance of such steps, but it has also exposed the vulnerabilities of the European Defense Technological and Industrial Base. This article provides an account of the development of EU defense-industrial policy since Russia’s war on Ukraine and it critically engages with some of the challenges that have emerged for Europe’s defense industry, EU Institutions and EU Member States. In so doing, the article asks whether the war on Ukraine will lead to a genuine step-change in EU defense-industrial cooperation.

On the Submission of Legal Terms in the Dictionary of International Words
Authors: Gedzevičienė Dalia
Published: April 2023

In order to determine whether the Dictionary of International Words (hereinafter TŽŽ2013) can be used as one of the sources of legal terminology in scientific and practical work, the terms denoting the concepts of law and their potential adjectival components were selected from the TŽŽ2013, the information provided with them was analysed, and the main features of the morphemic structure and semantics of the terms and their components were identified. Of the 676 legal terms found in the dictionary, 65% originate from Latin, 17% from French, 6.5% from Greek and 11% from other languages. The majority of legal noun terms are made up of all compounds with foreign roots, while all of the verb legal terms are to be regarded as hybrids since they are made up of a base with foreign roots and Lithuanian suffixes. 26% of the adjectival compounds are made of a foreign base and international suffixes, and around 70% are considered hybrids. The article also explores the discrepancies between the semantic fields of Lithuanian terms and their English equivalents. The TŽŽ2013, with certain reservations, can be used as one of the sources of legal terminology in law and language sciences as well as in practice.
The Connotation in Medieval Appositional Groups
Authors: Zbróg Piotr
Published: April 2023

Connotation as a syntactic mechanism of announcing a specific component in a sentence occurs or not in appositional groups. Based on the test for the non-ellipticity (or ellipticity) of the utterance, it can be determined whether the opposition base or the apposition itself is connoted (the sentence is then incomplete) or not (after the ellipse of the component, the sentence is still complete). Old Polish appositional groups of the type James and John, sons of Zebedee; Bolesław, priest and heir; chapter „Ut noxius” were reviewed in this article. They have been recorded from all monuments of the Polish language and constitute a representative collection of constructions of this type at that time. As a result of the analysis, it was found that in some types of expressions, the base was connoted (Mary, rose lights) or apposition (You, Lord). There were also groups with an unconnoted base (Piotr mayor from Koźmin) and an unconnoted apposition (stone, margarita). On this basis, the typology of the analyzed groups was established, distinguishing groups with unconnoted base and apposition, with connoted base and apposition, with unconnoted base and connoted apposition, and with connoted base and unconnoted apposition.
Ukrainian Poetic Sixties: Mykola Kholodnyi’s Creative Individuality
Authors: Urys Tetiana
Published: April 2023

The article is devoted to the little-studied Ukrainian poet of the sixties, dissident M. Kholodnyi, his creative style, analysis of motifs, images, and symbols of lyrical heritage, and the phenomenon of creative individuality. Socio-political reflection of Ukrainian tragedies, the role of the artist and his work singled out among the motifs of his poetry. There are images of famous Ukrainian writers who are carriers of the code of national memory and help to shape the national consciousness of future generations. A separate block constitutes his intimate lyric poetry reflecting the various facets of the spiritual and corporeal together with emotions ranging from romantic to deeply sensual. It is noted that among the writers of the 60s generation, his poetry is distinguished by the presence of sharp satire and tragedy in depicting paradoxical and absurd Soviet reality.
Treatment of Persistent Left Atrial Appendage Thrombus in Patients with Atrial Fibrillation on Adequate Oral Anticoagulation: Pathways of Care for All-comers and Heart Failure Patients
Authors: Katic Josip , Borovac Josip Andelo
Published: April 2023

In patients with AF, the presence of left atrial/left atrial appendage (LA/LAA) thrombus is related to an increased risk of thromboembolic events. Anticoagulation therapy, either with vitamin K antagonists or novel oral anticoagulants (NOACs) is therefore mandatory in AF with LA/LAA thrombus in order to lower the risk of stroke or other systemic embolic events. Despite the efficacy of these treatments, some patients will have persistent LAA thrombus remaining or may have contraindications to oral anticoagulation. Currently, little is known about the occurrence, risk factors and resolution rate of LA/LAA thrombus in patients who are already under optimal chronic oral anticoagulation, including vitamin K antagonists or NOACs. The common action in clinical practice in this scenario is switching from one to another anticoagulant drug exhibiting a different mechanism of action. Repeated cardiac imaging is then advised within several weeks to visually verify thrombus dissolution. Finally, there is a substantial scarcity of data on the role and optimal use of NOACs after LAA occlusion. The aim of this review is to critically evaluate data and provide up-to-date information on the best antithrombotic strategies in this challenging clinical scenario.

Published: April 2023

Although Scrum presents several advantages, process and final product quality continue to be Scrum’s main challenges. The quality assessment should be an essential activity in the software development process. Several authors have attempted to improve the quality of Scrum projects, changing some aspects of the framework, such as including new quality practices, a quality role, and quality processes. However, the quantification of quality is still a challenge. For that reason, the authors proposed a framework called Scrumlity, which was defined in a previous study. This framework proposes a change to Scrum, including a quality role and some artifacts to evaluate quality through a complete execution of a Sprint. In this study, the authors add a User Story Quality assessment to the framework. The User Story Quality Assessment includes over 250 analyzed User Stories. Results obtained after this experiment indicate the importance of executing a User Story Quality Assessment and that Scrum Team members are willing to accept adding this to the framework.

Published: April 2023

Systems Thinking Competencies have become extremely important and widely studied due to increasing systems complexity. Because of this, when they are taught, it is extremely useful to identify whether or not students own Systems Thinking Competencies in order to design a specific teaching strategy. This research applied an Adapted Holistic Scoring Method to assess Concept Maps developed by postgraduate and undergraduate engineering students in order to identify Systems Thinking Competencies. It had two phases. At the first one, Students showed an acceptable knowledge of cost estimation drivers, and a certain level of Systems Thinking Competencies. In the second phase, both cost estimation drivers and Systems Thinking Competencies showed an improvement. Mann-Whitney U-test was applied in order to identify if there were significant differences between Phase 1 and Phase 2. Confidence level of 95%, and a significance level of 0.05 was considered.

This paper presents forensic, bioarchaeological and historical research on eight human skulls discovered during the 2018 restoration of a nineteenth-century pastor’s tomb in the village of Gostków in Poland (which, until 1945, had been Giesmannsdorf in Germany). Local rumours suggested that the tomb had been used as a mass grave at the end of World War II for the remains either of war-crimes victims or of a murder-suicide incident. The research was undertaken at the request of the Fundacja Anna w Gostkowie (Anna Foundation in Gostków), which maintains the cemetery, and confirmed detailed witness accounts that the tomb contained the remains of two related German families in which some individuals had killed the others, including several children, and then themselves. The authors also discuss the phenomenon of suicides under war conditions and the cognitive, social and ethical problems of researching this topic.

Published: April 2023

Climate change, hydro-power dams and socio-economic development in the upper Mekong River, have caused changes in surface water resources and agricultural transformation in the Vietnamese Mekong Delta (VMD). It is unpredictable and influences decision-making processes on water resource management. This study aims at applying the DAPP (Dynamic Adaptive Policy Pathways) approach to develop solution roadmaps supporting rice production in the Mekong Delta projection to 2030 under the context of uncertain changes on surface water resources. Data were collected from local officers, farmers, experts at Can Tho University, Technical University Delft, and Utrecht University using semi-structured interview techniques including workshops, group discussions, and in-depth interviews. The consolidated solutions from stakeholder’s opinions were evaluated at different socio-economic and environmental dimensions, specially focused on the time of tipping point of each solution. The study results show that two solution roadmaps were developed as sample scenarios to promote rice production in the upper area of the VMD. The determination of the solutions roadmaps based on the agreement of the stakeholders, which is a new feature of this approach in linking many stakeholders for the general development of the region. The DAPP approach could be suitable to support decision-making on surface water resources management in the context of uncertain changes. Therefore, further studies can apply this approach to other regions in the VMD which will support to reinforce and demonstrate the applicability of the DAPP approach on supporting decision-making in the face of increasingly uncertain changes in the VMD.

Published: April 2023

Disasters deeply impact the health of the affected population and the economy of a country. The health burden of disasters in Brazil is underestimated and more studies are needed to underpin policies and actions for disaster risk reduction. This study analyzes and describes disasters that occurred in Brazil from 2013 to 2021. The Integrated Disaster Information System (S2iD) was accessed to obtain demographic data, disaster data according to Brazilian Classification and Codification of Disasters (COBRADE), and health outcome data (number of dead, injured, sick, unsheltered, displaced, and missing individuals and other outcomes). Database preparation and analysis were performed in Tableau. In total, 98.62% (50,481) of the disasters registered in Brazil from 2013 to 2021 are natural, with a significant increase in 2020 and 2021 due to the COVID-19 pandemic, a biological disaster. This disaster group also caused the highest number of deaths (321,111), as well as injured (208,720) and sick (7,041,099) people. By analyzing data for each geographic region, we observed differences regarding disasters frequency and their health outcomes. In Brazil, climatological disasters are the most frequent (23,452 events) and occur mainly in the Northeast region. Geological disasters have the highest lethality, which are more common in the Southeast; however, the most common disasters in the South and Southeast are those of the meteorological and hydrological groups. Therefore, since the greatest health outcomes are associated with disasters predicted in time and space, public policies for the prevention and management of disasters can reduce the impacts of these events.
Análise da influência do momento do ingresso em creches no desenvolvimento infantil
Authors: Batista Christyann Lima Campos , Brentani Alexandra Valéria Maria
Published: April 2023

Este estudo objetivou analisar a relação entre a idade de ingresso nos programas de educação na primeira infância (EPI) e o desenvolvimento infantil. Trata-se de um estudo transversal com dados oriundos da Coorte de Nascimentos da Região Oeste de São Paulo, Brasil. Realizou-se o acompanhamento de crianças nascidas no Hospital Universitário da Universidade de São Paulo durante 36 meses, entre os anos de 2012 e 2014, e de seus cuidadores respondentes durante a onda de seguimentos dos 36 meses de idade (realizada entre os anos de 2015 e 2017). O desenvolvimento infantil foi mensurado pelo instrumento Engle Scale do Projeto Regional de Indicadores de Desenvolvimento Infantil (PRIDI). Os programas de EPI foram avaliados em relação a sua qualidade. Foram utilizadas como variáveis expositivas as características sociais das crianças e dos seus cuidadores, bem como as características do contexto econômico e familiar. A amostra foi composta por 472 crianças e cuidadores. Observou-se que o ingresso na creche entre 13 e 29 meses foi o mais frequente. Quando considerados isoladamente, observou-se que uma maior idade de ingresso esteve associada com maior escore de desenvolvimento [β = 0,21, IC95%: 0,02; 0,40, p = 0,027]. Após a inclusão das variáveis de ajuste nos modelos de regressão, observou-se que estar inscrito em instituição do tipo privada, tempo total de aleitamento materno, horas trabalhadas fora de casa pelo cuidador principal e o controle inibitório foram determinantes para explicar o desenvolvimento infantil aos 36 meses na amostra. A idade de ingresso mais tardia nos programas de EPI pode ter efeito positivo sobre o desenvolvimento infantil aos 36 meses de idade, porém esses achados precisam ser ponderados.

Published: April 2023

ABSTRACT: Tropical dairy cattle farming is one the most relevant economic activities for food production; although, currently faces increasing scrutiny from society due to its potential harm to natural resources and the environment. Moreover, some factors are paramount for the evaluation of the sustainability and productive potential of any given tropical dairy farm: soil quality, profitability, and energy efficiency. This study carried out a sustainability analysis in four types of tropical dairy cattle ranches, through three key indicators (economic profitability, energy efficiency and soil quality) and with a comprehensive approach in the Costa region of Oaxaca, Mexico. Therefore, four farms of different sizes (i.e., small, medium, large, and very large) were selected in Costa de Oaxaca, Mexico. The data collection was carried out for daily milk production, the dynamics of farm inputs (introduction or removal) from the production system, alongside with collection of soil samples. The agroecosystems evaluated were economically profitable, and those with greater intensification of their pasture areas display higher profit margins and energy efficiency.

ABSTRACT: In the last decades, the high incidence of viruses transmitted by whiteflies has become a problem in the tomato fields, threatening, more recently, the potato crops. The present study carried out a survey of begomoviruses and criniviruses in tomato and potato crops, from 2015 to 2018, in the municipalities of Araucária, Campo do Tenente, Campo Largo, Contenda, Lapa, Faxinal, Morretes, Reserva, Castro, Palmeira and São Mateus do Sul, in Paraná State, Brazil. Total DNA and RNA from leaves were extracted and used as templates to detect, respectively, begomoviruses by PCR and criniviruses by RT-PCR. Out of 215 tomato samples, 14 from Faxinal were infected by crinivirus. The other tomato samples and 243 potato samples showed negative results for begomovirus and crinivirus. Results indicated a low incidence (6.5%) of crinivirus infecting tomato crops in Paraná State, and the nucleotide sequence of one amplified fragment shared 99.71% identity with tomato chlorotic virus (ToCV).

ABSTRACT: Verminosis in small ruminants can render rural activity impractical, which is still controlled through the administration of anthelmintics. The present study evaluated four agro-industrial residues as fertilizer in the control of GIN of small ruminants in the free-living stage. Crab shell, manipueira, biochar, and organomineral residues were used in pots (5.0 kg of soil) and cultivated with Massai grass (Megathyrsus maximum cv. Massai). Further, the pots were contaminated with feces from sheep carrying a natural multispecific infection by GIN. Next, the residues were applied individually to the soil, with 50 mL/pot for liquid and 50 g/pot for solid residues. Treatment with manipueira showed the lowest number of L3.kg MS-1 recovered from the grass (202.44), when compared with treatments using organomineral (823.89) and biochar (689.34). However, there was no statistically significant difference (P < 0.05) between the four treatments as compared to the control group. These agro-industrial residues can be used as organic fertilizers; however, these will not help in the control of GIN in sheep.

ABSTRACT: Foot-and-mouth disease (FMD) is a viral disease that affects several animal species, including domestic and wildlife ones. The occurrence of an FMD outbreak can potentially cause a large negative impact on countries or regions’ livestock production and economy. Performed over several decades, mass herd vaccination has been the main strategy to control the disease. However, countries are beginning the stage of eradicating FMD, which involves suspending vaccinations. The present study carried out a risk classification for FMD occurrence in Goiás State, Brazil by evaluating and combining multiple risk factors involved in FMD introduction and dissemination. Data from 126,345 rural properties were collected and categorized by municipality. The risk factors were grouped into two modules and then scores for each module were obtained by adding and weighting the risk factors. These combined scores resulted in the final FMD occurrence risk score. Most of the municipalities, as well as the herds were found in the lowest likelihood levels. Variables linked to herd density and animal movement played a key role in the score composition. We believed that this model can be a useful tool in the decision-making process regarding actions and strategies related to FMD eradication.

ABSTRACT Objectives: This study aimed to compare the functional and radiological results of patients who had intra-articular comminuted distal radius fractures and were operated on with external fixation percutaneous pinning or the volar-dorsal combined plate osteosynthesis. Methods: In this study, 49 patients operated on and followed up for the comminuted distal radius fractures between May 2015 and January 2019 were retrospectively evaluated. The surgical outcomes of the patients, who were operated on with combined dorsal-volar plate osteosynthesis or external fixation percutaneous pinning, were compared in this study. Functional and radiological scores were evaluated and analyzed statistically. Results: There was no statistical difference between external fixation and volar-dorsal combined plate groups regarding the Disabilities of the Arm, Shoulder, and Hand (DASH) questionnaire, the Visual Analog Scale (VAS), the Mayo scoring system, range of motion, and grip strength values. Discussion: Although the combined volar-dorsal plate osteosynthesis technique had a longer operation time and a more complicated surgical procedure, the combined volar-dorsal plate osteosynthesis had lower complication rates and permitted early mobilization. The combined volar-dorsal plate osteosynthesis could be an alternative to external fixation percutaneous pinning. Level of Evidence III, Therapeutic Studies Investigating the Results of Treatment.

ABSTRACT Objectives: The aim was to evaluate the viability and the outcomes of the sural flap performed with the pedicle covered by a strip of skin. Methods: A prospective cohort of 20 consecutive cases were evaluated in terms of flap viability, complication rate, and the amount of skin graft required. The location of the defects was the middle third of the tibia in 3 cases, the ankle and hindfoot in 15 cases, the middle foot in 1 case, and the forefoot in 1 case. The flap design was the same as described by Masquelet. The only modification included a strip of skin over the entire length of the pedicle. The intermediary skin between the donor site and the defect was incised and the skin was undermined to accommodate the pedicle without compression. Results: All cases had a satisfactory evolution, with adequate healing and without flap loss. Both the donor site and the pedicle were primarily closed in all cases. In one patient, the flap developed a limited area of superficial epidermolysis that healed spontaneously. Conclusion: the modified sural flap with a covered pedicle is feasible and reliable with a lower rate of complications when compared with the conventional sural flap.

IMPACTS OF INSTABILITY TRAINING ON THE PHYSICAL FITNESS OF SOCCER STUDENTS
Authors: Guo Kai
Published: April 2023

ABSTRACT Introduction: Most coordination studies are conducted in stable environments, unable to realistically simulate an environment integral to the sports field. The concept of instability training applies the principles of sports physiology, combining real situations from the soccer game to improve students’ sporting ability, and has gained attention from coaches, although it still lacks scientific evidence. Objective: Study the concept of instability training by evaluating its optimization and development effects on soccer students’ motor coordination. Methods: Fifty college soccer students were selected. The students were randomly divided into experimental and control groups, without relevant statistical differences. The experiment lasted one hour daily, three times a week, for six weeks. The control group remained with the usual training while the experimental group had the instability training protocol added. Balance test results were collected with frontal and posterior lower limb support and comprehensive posterolateral scores. Changes in activity performance were also analyzed with the results collected before and after the intervention. Results: The score of the experimental group without support was increased from 101.14 ± 8.22 to 108.73 ± 8.54, higher than the control group (103.8 ± 58.11). The comprehensive score of the experimental group was from 88.85 ± 6.10 to 99.85+8.87, also higher than the control group (88.15 ± 6.43). Conclusion: The effects of instability training to optimize and develop motor coordination in soccer students proved to be superior to usual training, and its introduction into daily training is indicated for more effective promotion of students’ fitness level.

ABSTRACT Introduction: Corporal balance and psychomotor coordination are factors of extreme importance in the physical fitness of tennis players. It is believed that implementing training with instability in training can have repercussions in a better capacity of action influencing positively in the sports practice. Objective: Explore whether the addition of instability training to daily training can influence the physical fitness of tennis players. Methods: For this experiment, 100 national secondary professional tennis players were selected as volunteers, and divided equally into experimental and control groups. The experimental group received 12 weeks of additional intervention with instability training, while the control group remained with standard training. Pertinent data were collected before and after the intervention, statistically analyzed, and compared to the literature. Results: Anterior motion range of motion in the experimental group increased from 28.965 ± 0.418 to 39.357 ± 0.25; anterior motion accuracy increased from 26.258 ± 2.239 to 34.608 ± 0.342. Posterior stroke range of motion increased from 25.026 ± 2.136 to 34.528 ± 0.10, and posterior motion accuracy increased from 18.230 ± 1.096 to 28.225 ± 0.261. The data in the control group did not show significant changes. Conclusion: Instability training added to tennis players’ daily training may influence tennis players’ balance ability and movement coordination, positively impacting tennis players’ fitness.

Authors: Zheng Zheng , Xia Qiudong
Published: April 2023

ABSTRACT Introduction: Despite the intrinsic benefits of sports practice, the adherence to tennis by a large part of the population without the due physical preparation apparently resulted in a high rate of knee joint injuries in tennis players, either in daily training or competitions. Objective: Prevent tennis players’ knee joint injuries by exploring ways to improve lower limb joint stability. Methods: This paper selected 50 national second-level professional tennis players and divided them into two groups. Both groups had daily tennis training, but the experimental group experienced additional lower limb flexibility exercises. Results: The tennis players in the experimental group increased their seated forward flexion from 22.19 cm to 26.96 cm, the knee joint extensor muscle strength index increased from 142.69 to 176.23, and the knee joint flexor muscle strength index increased from 93.21 to 149.28, P<0.05, with significant differences. The general stability index was changed from 0.23 to 0.20, the internal and external indices varied from 0.13 to 0.08, and the frontal and posterior indices changed from 0.13 to 0.08. Conclusion: Knee joint injuries in tennis players can be effectively combated by adding lower limb flexibility exercise protocol to daily training.
