Comprensión lectora de textos continuos y discontinuos mediante estrategias metacognitivas
Authors: Herrera Viana María Catalina , Gallego Betancur Teresita María
Published: October 2023

El propósito de este estudio fue entender el proceso de desarrollo de la comprensión lectora de textos continuos y discontinuos mediante estrategias metacognitivas, con el fin de analizar y describir aspectos importantes del aspecto literal, inferencial y crítico en las niñas y los niños del grado segundo. Se planteó como metodología un estudio de corte cualitativo, con el método de etnografía escolar, a través de las técnicas observación participante, entrevistas semiestructuradas y talleres. Los resultados más significativos parten de considerar que la lectura es un proceso constructivo y que las niñas y los niños pueden acceder a la comprensión tanto de los textos continuos como discontinuos con la mediación de la metacognición que perfila a un lector no solo apasionado por la lectura, sino crítico en el medio social y cultural al que pertenece. Finalmente, las estrategias metacognitivas posibilitan que el ejercicio de comprensión lectora sea más eficaz, a la vez que abren la reflexión de los estudiantes sobre su aprendizaje comprensivo, hecho que los vincula con el nivel crítico intertextual.
El cuerpo habla: arte y acontecimiento

Narrativas de las miradas: evocación de sentidos y experiencias corporales
Authors: Bohórquez Juliette
Published: October 2023

Es una reflexión generada a partir de “tomar prestada[1]” la experiencia que tuvieron algunos participantes del Taller Itinerante de Arte para La Paz -TIAP- Medellín con el uso de la cámara subjetiva, buscando un acercamiento que permitiera ver, leer e interpretar los usos del y con el cuerpo en el taller desarraigo. Puntos de vista que generan unas narrativas corporales que tienen correspondencia con el territorio, en tanto el cuerpo mismo es concebido como tal, a la vez que se integra y dispone dentro de este; propiciando correlatos que dan cuenta sobre esas maneras de relacionamiento y descripciones de acciones, sensaciones, emociones y significados, como de memorias manifestadas dentro de ellos; convirtiéndose en otra forma, diferente a la oral, de relatar, en este caso, experiencias de desarraigo.

Published: October 2023

The purpose of the present work is investigating a degenerate parabolic equation with anisotropic p-Laplacian operator and strongly nonlinear source under boundary conditions of Dirichlet type;
the existence of a periodic non-negative solution is shown. The proof is based on the Leray–Schauder topological degree, which is tricky to work with in this kind of equations.
Naringin ameliorates 5-fluorouracil elicited neurotoxicity by curtailing oxidative stress and iNOS/NF-ĸB/caspase-3 pathway
Authors: Zhou Peili , Wang Zhongfang , Chen Cheng , Famurewa Ademola C. , Olatunji Opeyemi Joshua
Published: October 2023

This study evaluated the protective effects of naringin (NRG) against 5-fluorouracil (5-FU)-elicited neurotoxicity. The animals were orally administered with NRG and subsequently injected with 5-FU. Injection of 5-FU caused depression in cerebral antioxidant enzymes, including glutathione peroxidase, superoxide dismutase, catalase, reduced glutathione and total protein levels, whereas malondialdehyde and acetylcholinesterase levels/activities were considerably upregulated. In addition, 5-FU-triggered cerebral pro-inflammation was shown via significantly increased levels of pro-inflammatory cytokines, inducible nitric oxide synthase, nuclear factor-ĸB, and caspase-3. Furthermore, necrotic and inflammatory histopathological lesions were observed in the cerebral tissues. Interestingly, the NRG administration considerably inhibited 5-FU-instigated cerebral oxido-inflammatory and apoptotic parameters in the treated animals. Thus, NRG could mitigate the neurotoxicity of 5-FU via the inhibition of oxido-inflammation and apoptosis in rats. These results suggested that NRG may have a relevant therapeutic importance in the management of 5-FU-elicited neurotoxicity.
Graphical solutions to one-phase free boundary problems
Authors: Engelstein Max , Fernández-Real Xavier , Yu Hui
Published: October 2023

We study viscosity solutions to the classical one-phase problem and its thin counterpart. In low dimensions, we show that when the free boundary is the graph of a continuous function, the solution is the half-plane solution. This answers, in the salient dimensions, a one-phase free boundary analogue of Bernstein’s problem for minimal surfaces.
As an application, we also classify monotone solutions of semilinear equations with a bump-type nonlinearity.

Published: October 2023

Pozzolanic materials, glass powder, and silica fume (SF) have all been used in concrete recently as a partial cement substitution to increase the strength of the concrete. The aim of this study is to analyze the impact of waste glass powder (WGP) and SF combination on high-strength concrete (HSC) characteristics. The working methodology of the current research consists of using SF passed through sieve No. 200, and WGP particles that passed through sieve No. 400 (particle size less than 38 µm), maximum size of aggregate (14, 20) mm and W/C + p (0.25, 0.35, and 0.45). The used waste materials were in three different amounts of SF and WGP (5, 10, and 15%) by weight of cement. HSC was tested for compressive strength, density, and ultrasonic pulse velocity (UPV) with various glass powder and SF contents. The obtained results show that after 7 and 28 days, concrete specimens containing 15% glass powder and SF demonstrated an increase in density, UPV, and compressive strength, depending on the test results. Conversely, concrete specimens with 5% SF and WGP had decreased compressive strength, UPV, and density. It was detected that WGP gave high mechanical (compressive strength) and physical properties (density and UPV) than SF with a ratio of 15% and lower properties with a ratio of 5%. In HSC manufacturing, glass powder may be used instead of SF.
Open orbits and primitive zero ideals for solvable Lie algebras
Authors: Baklouti Ali , Ishi Hideyuki
Published: October 2023

The aim of the paper is to provide a characterization criterion of exponential solvable Frobenius Lie algebras (having open coadjoint orbits), in terms of primitive ideals of the associated enveloping algebra.
In the case of complex solvable Lie algebras, we also show that an algebraic adjoint orbit is open if and only if the associated primitive ideal through the Dixmier map is trivial.
Electrostatic system with divergence-free Bach tensor and non-null cosmological constant
Authors: Leandro Benedito , Lousa Róbson
Published: October 2023

We prove that three-dimensional electrostatic manifolds with divergence-free Bach tensor are locally conformally flat, provided that the electric field and the gradient of the lapse function are linearly dependent. Consequently, a three-dimensional electrostatic manifold admits a local warped product structure with a one-dimensional base and a constant curvature surface fiber.

Moreover, we also study the concentration phenomenon of the ground state solutions.
As far as we know, our results seem to be new concerning the fractional (N/s)-Laplacian equation with the Choquard reaction.

In this study, singular Sturm–Liouville operators on a star graph
with edges are investigated. First, the behavior of sufficiently large eigenvalues is
learned. Then the solution of the inverse problem is given to determine the
potential functions and parameters of the boundary condition on the star graph
with the help of a dense set of nodal points. Lastly, a constructive solution to the inverse problems of this class
is obtained.
Developmental scores in offspring of women with subclinical hypothyroidism in pregnancy are affected by gender and thyrotropin cutoff
Authors: Stryhn Julie Kristine Guldberg , Væver Mette Skovgaard , Hoffmann Anne Lisbeth , Gæde Peter Haulund
Published: October 2023

Objectives

Subclinical hypothyroidism (SCH) is defined by elevated thyrotropin (TSH) and normal level of thyroxine (T4). The definition of SCH and the cutoff for TSH normality in pregnancy are debated. In the present study, we assess offspring perinatal outcome, anthropometrics and early development in relation to different TSH levels.

Methods

An observational study with 77 singleton-pregnant women included by thyroid screening before a planned cesarean section. Two TSH-cutoffs (3.0 and 3.7 mIU/L) defined euthyroid and SCH groups, and were applied to evaluate offspring anthropometrics, complication rates (maternal blood loss, Apgar-score, cord arterial-pH, admission to neonatal intensive care unit, perinatal hypoglycemia) and offspring development. Development was evaluated by Bayley-III test in a subsample at age 6 months (n=27) and 15 months (n=22).

Results

Prevalence of SCH was 31.2 % at TSH-cutoff 3.0 mIU/L, and 16.9 % at TSH-cutoff 3.7 mIU/L. No differences in complications and anthropometrics were observed. In Bayley-III tests, cognitive score was decreased at 6 months (p=0.012) and at 15 months (p=0.056) by applying TSH-cutoff 3.0 mIU/L. At cutoff 3.7 mIU/L, motor score was decreased at 15 months (p=0.020). Male offspring had significantly lower cognitive scores at age 6 and 15 months (TSH-cutoff 3.0 mIU/L), and motor scores at age 15 months (TSH-cutoff 3.7 mIU/L).

Conclusions

The importance of the definition of thyroid normality in pregnancy is underlined. This study suggests that a gender-effect might be present in maternal thyroid disease, and that developmental differences exist if TSH-cutoff is low. Further research is needed.

Published: October 2023

Objectives

The COVID-19 pandemic imposed many challenges on pregnant women, including rapid changes to antenatal care aimed at reducing the societal spread of the virus. This study aimed to assess how the pandemic affected perinatal mental health and other pregnancy and neonatal outcomes in a tertiary unit in Queensland, Australia.

Methods

This was a retrospective cohort study of pregnant women booked for care between March 2019 – June 2019 and March 2020 – June 2020. A total of 1984 women were included with no confirmed cases of COVID-19. The primary outcome of this study was adverse maternal mental health defined as an Edinburgh Postnatal Depression Scale score of ≥13 or an affirmative response to ‘EPDS Question 10’. Secondary outcomes were preterm birth <37 weeks and <32 weeks, mode of birth, low birth weight, malpresentation in labour, hypertensive disease, anaemia, iron/vitamin B12 deficiency, stillbirth and a composite of neonatal morbidity and mortality.

Results

There were no differences in the primary perinatal mental health outcomes. The rates of composite adverse neonatal outcomes (27 vs. 34 %, p<0.001) during the pandemic were higher; however, there was no difference in perinatal mortality (p=1.0), preterm birth (p=0.44) or mode of delivery (p=0.38).

Conclusions

Although there were no adverse consequences on maternal mental health during the pandemic, there was a concerning increase in neonatal morbidity potentially due to the altered model of maternity care implemented in the early COVID-19 pandemic.

In recent years, there has been a growing effort to join forces and address common challenges on their continents, and the world along with countries have become more interconnected and interdependent. In this article, we will try to explain the historical image and connections and interactions of the development of nomadic civilizations as widely as possible, i.e., in the context of the world, and compare them with Mongolia in terms of logical connections.
Assessment of noise pollution and associated subjective health complaints in Jharia Coalfield, India: A structural equation model analysis
Authors: Tiwari Shashi Kant , Kumaraswamidhas Lakshmi Annamalai , Garg Naveen
Published: October 2023

Noise pollution in the mining industry has become a serious concern in recent years and has aroused extensive health complaints for the mine workers. Despite the increasing knowledge of the association between noise exposure and health effects, only a few studies have investigated the adverse health effects due to noise pollution in the mining industry. The present study aims to determine the interrelationship of mining noise (MN), demographic characteristics (DC), noise sensitivity and noise annoyance (NA) with subjective health complaints (SHC). A PLS-SEM approach has been used to assess the direct and indirect relationship between the influencing factors on the SHC of 272 people in the mines. Field measurements were made using a sound level meter to evaluate the ambient noise levels for 1 h duration during day and night hour shifts in Dhansar and Bastacolla mining areas of the Jharia coalfield. The noise maps revealed that most of the locations have noise levels higher than 70 dB(A). The statistical model suggests that NA is the most important predictor of SHC. Besides, DC and MN induce only indirect effect on SHC. The study shall facilitate in developing a decision support tool for the assessment of noise levels, induced annoyance, SHC, and suitable policy interventions for controlling noise exposure among mine workers in the coalfield.

Published: October 2023

The pollution of silver ion (Ag(i)) has become a serious environmental threat and hazard to ecosystem and human health. Thus, the nanoscale zero valent iron (nZVI)-doped polypyrrole-based carbon nanotube (nZVI/CNT) composites were synthesized by a facile method to remove Ag(i) from wastewater due to the toxicity and scarcity nature of Ag(i). In this process, Fe3+ initiated the self-assembly of polypyrrole tubes in the presence of methyl orange, while it also served as an iron source generated nZVI/CNTs by carbothermal reduction method. The nZVI/CNT composites exhibited a homogeneous tubular structure, and the nZVI formed were uniformly dispersed in the nZVI/CNT composites. The nZVI/CNT composites were used as an adsorbent for the removal of Ag(i) and showed a higher adsorption capacity compared to nZVI and CNTs, with a maximum adsorption capacity of 522.41 mg g−1. Ag(i) was adsorbed on nZVI/CNT composites by ion exchange and chelation, where Ag(i) was reduced to non-toxic Ag due to the redox reaction among pyrrolic-N, nZVI, and Ag(i). The adsorption process of Ag(i) on nZVI/CNT composites was dominated by monolayer adsorption. According to our results, nZVI/CNT composites can be used as economical treatment for wastewater containing Ag(i).
Improving anti-aging performance of terminal blend rubberized bitumen by using graft activated crumb rubber
Authors: Xie Juan , Zhao Xucheng , He Wen , Zhang Yongning , Xin Yabing
Published: October 2023

The appearance of terminal blend rubberized bitumen (TB) has improved a series of defects of traditional rubber bitumen, such as high viscosity, poor storage stability. Therefore, its wide application prospect is self-evident. However, different degrees of thermal-oxidative aging problem still exist in the process from production to use of TB, which seriously affects the service life of pavement. To improve the anti-aging performance of TB, grafting activated crumb rubber (GACR) was obtained by using acrylamide, and then compounded with TB. Firstly, TB was prepared in the self-developed nitrogen protection device. Secondly, GACR modified bitumen (GACR-MB), TB/CR composite modified bitumen (TB/CR) and TB/GACR composite modified bitumen (TB/GACR) were developed in the atmospheric environment. Finally, the performance of four kinds of crumb rubber modified bitumens before and after aging was compared and analyzed by testing high and low temperature rheological properties. The results show that GACR slowed down the formation rate and aggregation degree of asphaltenes and other macromolecular substances, and TB/GACR showed excellent aging resistance.

Carder, MJ, Scudamore, EM, Savanna, KN, Pribyslavska, V, Bowling, LR, and O'Neal, EK. Retrospective and contemporary predictors of National Collegiate Athletic Association Division I cross-country performance are sex specific. J Strength Cond Res 37(11): 2267–2272, 2023—The purpose of this study was to identify National Collegiate Athletic Association (NCAA) Division I cross-country (XC) performance potential using laboratory-based and field-based parameters and retrospective high school (HS) personal best (PB) data at various distances of current collegiate XC runners. Fifteen female and 17 male NCAA XC runners provided their PB for 5-km (women) and 8-km (men) distances from the previous season. Bivariate correlation and stepwise and hierarchical regression modeling were used to predict XC performance. Single squat jump height and multijump reactive strength index displayed r < 0.27 for both sexes, suggesting lower-body power is a poor predictor of XC performance or masked by other factors of greater importance. Triceps skinfold thickness approached significance (r = 0.43; p = 0.09) for men but was unrelated to women's performance (r = −0.05; p = 0.86). HS XC PB neared significance (r = 0.55, p = 0.054), but no other single or combination of variables reached significance for female runners. Aerobic capacity displayed a moderate to strong relationship (r = 0.65) for male runners. High school 3,200-m PB for men produced a robust prediction capacity (r = 0.85; p = 0.005, SEE = ± 0.65 minutes), and predicted 8-km PB within 30 seconds for approximately two-thirds of runners. These outcomes suggest when recruiting HS or transfer athletes, male and female XC runners should not be recruited on the same factors. Women's XC PB is more difficult to predict, but skinfold thickness was statistically the least valuable predictor of all factors.

Jiménez-Lozano, M, Yáñez-García, JM, Mora-Custodio, R, Valle-Salguero, A, Díez-Fernández, DM, Franco-Márquez, F, González-Badillo, JJ, and Rodríguez-Rosell, D. Load-time and load-speed relationship in the resisted sled sprint exercise: what independent variable most accurately determines the relative load? J Strength Cond Res 37(11): 2167–2177, 2023—The aims of this study were to analyze the load-speed and load-time relationships in the resisted sled sprint exercise using different variables as relative load and to estimate the decrement of speed sprint and the increase of sprint time across different loads. Thirty young healthy men performed a progressive loading test in the countermovement jump (CMJ) exercise to determinate the load that elicited a 2 m·s−1 peak velocity (PV2-load) and in the full squat exercise to obtain the 1 repetition maximum (1RM) value and the load that elicited a 1 m·s−1 mean velocity (V1-load). In addition, subjects performed a progressive loading test in the resisted sled sprint exercise, whereas time and instantaneous speed at 10 (T10 and V10) and 20 m (T20 and V20) were measured. The independent variables used were body mass (BM), 1RM and V1-load in the squat exercise, the PV2-Load in the loaded CMJ exercise, 1RM + BM, V1-Load + BM, and PV2-Load + BM. To analyze whether relationships were dependent on individual performance obtained in unloaded sprint, the total sample was divided into 3 subgroups: high performance (T20 < 3.00 s), medium performance (T20:3.00–3.12 s), and low performance (T20 > 3.12 seconds) groups. The independent variables showing the highest relationships with time and speed in 10 and 20 m were %BM, %BM + V1-load, and %BM + PV2-load. Statistically significant differences between performance groups in %DSS (decrease of sprint speed) and %IST (increase sprint time) in 20 m were found when %BM was used as relative load, whereas there were no significant differences between groups for %BM + PV2-load or %BM + V1-load. In conclusion, the use of %BM + PV2-load and %BM + V1-load should be considered as variables for monitoring the relative load in the resisted sled sprint exercise.

Ishida, A, Draper, G, Wright, M, Emerson, J, and Stone, MH. Training volume and high-speed loads vary within microcycle in elite North American soccer players. J Strength Cond Res 37(11): 2229–2234, 2023—The purposes of this study were to reduce dimensionality of external training load variables and examine how the selected variables varied within microcycle in elite North American soccer players. Data were collected from 18 players during 2018–2020 in-seasons. Microcycle was categorized as 1, 2, 3, 4, 5 days before match day (MD-1, MD-2, MD-3, MD-4, and MD-5, respectively). Training load variables included total distance, average speed, maximum velocity, high-speed running distance (HSR), average HSR, HSR efforts, average HSR efforts, sprint distance, average sprint distance, sprint efforts, average sprint efforts, total PlayerLoad, and average PlayerLoad. The first principal component (PC) can explain 66.0% of the variances and be represented by “high-speed load” (e.g., HSR and sprint-related variables) with the second PC relating to “volume” (e.g., total distance and PlayerLoad) accounting for 17.9% of the variance. Average sprint distance and total distance were selected for further analysis. Average sprint distance was significantly higher at MD-3 than at MD-2 (p = 0.01, mean difference = 0.36 m•minute−1, 95% confidence intervals [CIs] = 0.07–0.65 m•minute−1) and MD-4 (p = 0.012, mean difference = 0.26 m•minute−1, 95% CIs = 0.10–0.41 m•minute−1). Total distance was significantly higher at MD-3 than at MD-1 (p < 0.001, mean difference = 1,465 m, 95% CIs = 1,003–1926 m), and MD-2 (p < 0.001, mean difference = 941 m, 95% CIs = 523–1,360 m). Principal component analysis may simplify reporting process of external training loads. Practitioners may need to choose “volume” and “high-speed load” variables. Elite North American Soccer players may accumulate higher average sprint distance at MD-3 than at other training days.

J Strength Cond Res 37(11): 2235–2240, 2023—This study described the change in training and match internal loads, plus perceptual wellness during the transition between club and national teams (NTs) for female international footballers (soccer). Session count, session rating of perceived exertion (s-RPE), and perceptual wellness data were collected from 42 players from 1 NT between 2019 and 2021 for 7 NT tournaments. Data were collated into 7-day (1 week) microcycles to compare the 2 weeks before the first week of NT (transition in: NT-2, NT-1, NT1); and separately from the final NT week to the next 2 weeks in clubs (transition out: NTFinal, NT+1, NT+2). Data were analyzed using linear mixed-models, with session count, s-RPE or wellness as the outcome variable, week as the fixed effect, player name, and tournament as random effects. Tukey's adjusted post-hoc comparisons and Cohen's d effect sizes (ES) were compared between weeks. Significance level was set at p < 0.05. During the transition into NT, training and total session counts increased (p < 0.0001, ES > 0.67), training s-RPE increased (p = 0.012, ES = 0.35), whereas match count and s-RPE decreased (p < 0.05, ES < −0.34). During the transition out of NT, there were decreases in training session count (p < 0.05, ES < −0.37), match count, and total session count (p < 0.0001, ES < −0.86), and match and total s-RPE (p < 0.0001, ES < −0.63). Perceived wellness was not significantly different throughout (p > 0.05, ES = −0.34 to 0.35). Thus, training and match exposures differ between club and NTs, demonstrating these unique transitional periods require simple and effective load monitoring to inform training and recovery prescription when changing between club and NTs.

Cabarkapa, D, Cabarkapa, DV, Philipp, NM, Knezevic, OM, Mirkov, DM, and Fry, AC. Pre-post practice changes in countermovement vertical jump force-time metrics in professional male basketball players. J Strength Cond Res 37(11): e609–e612, 2023—Despite the countermovement vertical jump (CVJ) being one of the most popular noninvasive and time-efficient methods for monitoring neuromuscular status, there is a lack of scientific literature focused on examining fatigue-induced alterations in performance in elite athletes. Thus, the purpose of this study was to examine changes in force-time metrics pre-post practice in professional male basketball players. Seventeen athletes competing in first-tier and second-tier national basketball leagues in Europe participated in this study. While standing on a uniaxial force plate sampling at 1,000 Hz, each athlete completed 3 CVJs pre-practice and post-practice. The practice consisted of individual and team shooting drills, position-specific player development drills, 5-on-0 offensive actions, and 5-on-5 play, including full-court transition (∼2 hours). The findings reveal that pre-post practice changes in force-time metrics seem to be phase specific. Despite a trivial increase in eccentric mean force (920.4 ± 100.2, 929.4 ± 100.0 N), most changes were observed within the concentric phase of the CVJ. The concentric phase duration increased pre-post practice (0.233 ± 0.027, 0.242 ± 0.033 seconds), whereas concentric impulse (262.9 ± 18.8, 258.6 ± 21.6 N·s), peak velocity (2.93 ± 0.22, 2.86 ± 0.22 m·s−1), mean force (2052.4 ± 179.2, 2002.7 ± 188.2 N), mean power (3,165.5 ± 269.5, 3,030.9 ± 326.8 W), and peak power (5,523.4 ± 607.3, 5,246.6 ± 663.7 W) experienced a significant decrease. Moreover, alongside longer contraction time (0.663 ± 0.065, 0.686 ± 0.074 seconds), lower vertical jump height (41.0 ± 6.8, 38.9 ± 6.6 cm) and reactive strength index-modified (0.634 ± 0.113, 0.579 ± 0.111 m·s−1) values were observed post-practice. Overall, these findings may allow practitioners to detect fatigue-induced changes in CVJ force-time metrics in professional male basketball players that can ultimately improve the acute and longitudinal training-adaptation monitoring process.

Horsley, BJ, Tofari, PJ, Halson, SL, Kemp, JG, Johnston, RD, and Cormack, SJ. Thoracic-worn accelerometers detect fatigue-related changes in vertical stiffness during sprinting. J Strength Cond Res 38(2): 283–289, 2024—Thoracic-mounted accelerometers are valid and reliable for analyzing gait characteristics and may provide the opportunity to assess running-related neuromuscular fatigue (NMF) during training and competition without the need for additional tests, such as a countermovement jump (CMJ). However, their sensitivity for detecting fatigue-related changes in gait across different speeds is unclear. We, therefore, assessed the changes in accelerometer-derived gait characteristics, including vertical stiffness (Kvert), following a repeated sprint protocol (RSP). Sixteen recreationally active subjects performed single and repeated CMJs on a force plate and 40 m run throughs overground at 3–4, 5–6, and 7–8 m·s−1 pre-post a 12 × 40 m RSP. Gait characteristics (contact time, step frequency, step length, Kvert, etc.) were derived from an accelerometer contained within a global navigation satellite system unit on the thoracic spine using a validated algorithm. Changes in running gait and CMJ performance were assessed using a linear mixed-effects model (95% confidence interval [95% CI]; effect size [ES]). Significance was set at p < 0.05. A significant reduction in Kvert occurred at 7–8 m·s−1 following the RSP (−8.51 kN·m−1 [−13.9, −3.11]; p = 0.007; ES [95% CI] = −0.39 [−0.62, −0.15]) which coincided with a decreased jump height (−0.03 m [−0.04, −0.01]; p = 0.002; ES [95% CI] = −0.87 [−1.41, −0.30]). However, all other gait characteristics were not significantly different irrespective of speed. Thoracic-worn accelerometers can detect changes in Kvert at 7–8 m·s−1 which may be useful for monitoring NMF during sprinting. However, a RSP does not result in altered gait mechanics in subsequent running at lower speeds.

Published: October 2023

Hydrotechnical constructures are complex structures that represent the interaction between soil-, water-and technological environment. For trouble-free and safe operation of hydrotechnical constructures, as well as maintaining them in operational mode, by the operating organization, as well as by organizations that conduct technical supervision, constant technical inspectionsare carried out to fix the damage (defects). This allows you to determine the actual technical condition of structures.Currently, building information modelling (BIM) methodology is most widely used for modelling structures. This methodology supports the seamless exchange of all information between relevant participants using digital technology. However, IFC files are mainly used to store data on structures. The evolution of this methodology provides for interoperability based on the network. The W3C LBD-CG community group presented an adapt extensible ontology called Building Topology Ontology (BOT), which provides ahigh-level description of the topology of structures, including the natures and types of hydrotechnical constructures depending on the purpose and operating conditions of structural elements of different levels. Authors have created an adapted ontology that does not have the same disadvantages as the IFC in terms of size and complexity. Reuse of existing ontologies has been an important priority, which allows the inclusion of ontologies for specialized areas.The issue of describing the technical conditionof hydrotechnical constructures is considered. Basic terms and statements are introduced that extend the multi-sorted language of applied logic to describe the knowledge of this subject area. The ontology model provides terminology for defining damage associated with hydrotechnical constructures. The ontology model makes it possible to introduce into the developed ontologies the relationship of damages with structural elements and spatial zones of their location. The ontology can also be used to represent observations of the technical state of damage in a machine-interpreted format.

As an important oil crop in China and the world, the harvesting problem of Camellia oleifera has attracted much attention. Research is needed on mechanical characteristics of harvesting equipment. Explicit dynamics was used to establish a finite element model under a simulated load response to the branch-pedicel-fruit system of C. oleifera to predict the fracture process at the pedicel junction. The separation mechanism of C. oleifera fruit was determined by measuring the constitutive parameters of fruit branches and pedicels and conducting separation experiments and explicit dynamics simulations on different hanging fruits. The maximum stress at the fruit pedicel was 1.14 MPa, and the goodness of fit between the simulation and experiment was approximately 89.5%, indicating that the branch-pedicel-fruit finite element model could accurately reflect the fruit shedding process and that the pedicel diameter was correlated positively with the separation force. This study provides technical parameters for the optimized design of existing C. oleifera harvesting equipment.

Traditional artisanal cheeses are known in Chile and Argentina as country cheeses, or in some other places as farm cheeses or farmhouse cheeses. All these terms are used to refer to cheeses made in small workshops or cheese factories, where the process is carried out by hand by the same members of the family and with a minimum presence of employees. A distinctive feature of cheese production is that the production processes have incorporated elements of the culture and environment in which the activity takes place. the purposes of this article referred to characterize the artisanal cheese factory and its producers in the context of the Araucanía Region in Chile. The region of La Araucanía is located in Chile, between the regions of Bío Bío and Los Ríos. Its area is 31,842 km² and its regional capital is the commune of Temuco. The type of study is quantitative of a transitional-descriptive type in 19 communes and 137 cheese producers of the provinces of Malleco and Cautín in the region of La Araucanía, territories where the cheese producers that are part of the sample are located. The characteristics of the producers, cheese factories and processes associated with the production of cheese, account for a cheese reality that has a set of potentialities and complexities necessary to consider not as problems of the artisanal cheese factory, but as realities and baselines on which it works and it is necessary to continue working in post of its empowerment and its value as part of the agri-food production system in the region of La Araucanía-Chile.

Published: October 2023

This article analyzes the international normative legal documents and the national legislation of the Republic of Uzbekistan on ensuring public safety. Due to the fact that threats and aggressions to public security are increasing and their social danger is increasing, international documents on ensuring public security are being developed in the fields of combating terrorism and extremism, corruption, organized crime, illegal circulation of narcotics and psychotropic substances, human trafficking, as well as railway, air and automobile. classified into normative legal acts on ensuring safety in the fields of transport and traffic safety. In recent years, the reforms implemented in Uzbekistan to ensure public safety have been discussed, and some legal gaps in public safety, in particular, the need for legal protection of public safety during rallies, gatherings and demonstrations, have been justified. The importance of effective implementation of measures on public order and security is based on the activities of the Ministry of Internal Affairs and National Guard units, which are the main entities responsible for ensuring public safety during these events. It is also proposed to study social relations in the field of theoretical and legal provision of public safety based on their content, regulatory legal documents, and directions of activity of entities providing public safety.
