The Role of Association: New Thinking on “Exposition, Comparison, Association” in Films
Authors: Wang Haizhou , Yu Jian
Published: March 2023

Crucial to the exploration of the nationalization of Chinese films, the concept of exposition (赋 fu), comparison (比 bi), and association (兴 xing) in films has gained much significance. While these concepts still need refining, an in-depth exploration of the terms is still necessary. This article reviews the theoretical term exposition, comparison, association, and argues that it should not be treated simply as pure rhetorical discourse. In particular, any interpretation of association should address the historical and cultural context of early Chinese society, and the early analogical thinking implied in association should be taken as an entry point for exploring the ambiguous ideographic role revealed by this aesthetic concept and extend it to film studies, so as to capture the unique image thinking in Chinese films and other Eastern cinema, which differs from the aesthetic logic of Western films.
An intelligent algorithm for fast machine translation of long English sentences
Authors: He Hengheng
Published: March 2023

Translation of long sentences in English is a complex problem in machine translation. This work briefly introduced the basic framework of intelligent machine translation algorithm and improved the long short-term memory (LSTM)-based intelligent machine translation algorithm by introducing the long sentence segmentation module and reordering module. Simulation experiments were conducted using the public corpus and the local corpus containing self-collected linguistic data. The improved algorithm was compared with machine translation algorithms based on a recurrent neural network and LSTM. The results suggested that the LSTM-based machine translation algorithm added with the long sentence segmentation module and reordering module effectively segmented long sentences and translated long English sentences more accurately, and the translation was more grammatically correct.

Review of the pharmacokinetics of nanodrugs
Authors: Shao Xiaotong , Shi Changkuo , Wu Shuqing , Wang Fei , Li Wenliang
Published: March 2023

Nanodrug delivery systems (NDDSs) are a hotspot of new drug delivery systems with great development potential. They provide new approaches to fighting against diseases. NDDSs are specially designed to serve as carriers for the delivery of active pharmaceutical ingredients to their target sites, and their unique physicochemical characteristics allow for prolonged circulation time, improved targeting, and avoidance of drug resistance. Despite remarkable progress achieved in the preparation and efficacy evaluation of NDDSs, the understanding of the in vivo pharmacokinetics of NDDSs is still insufficient. Analysis of NDDSs is far more complicated than that for small molecular drugs; thus, almost all conventional techniques are inadequate for accurate profiling of their pharmacokinetic behaviour in vivo. In this article, we systematically reviewed the absorption, distribution, metabolism, and excretion of NDDSs and summarized the advanced bioanalytic techniques for tracing the in vivo fate of NDDSs. We also reviewed the physiologically based pharmacokinetic model of NDDS, which has been a useful tool in characterizing and predicting the systemic disposition, target exposure, and efficacy/toxicity of various types of drugs when coupled with pharmacodynamic modelling. We hope that this review will be helpful in improving the understanding of NDDS pharmacokinetics and facilitating the development of NDDSs.

Published: March 2023

The oxidation of atrazine herbicide from water was performed by using titanium dioxide (TiO2) nanoparticles synthesized via the sol-gel method. A batch-scale photocatalytic reactor was designed for experimental work. The process was monitored using a UV–visible spectrophotometer. Operational parameters such as catalyst loading and pollutant concentration were investigated. The X-ray diffraction confirmed the anatase phase and high purity of the synthesized particles. Fourier transform infrared showed the functional group of titanium (Ti–O–Ti). The morphology of synthesized nanoparticles was characterized by scanning electron microscopy and transmission electron microscopy, which exhibited the irregular shape of nanoparticles along with aggregations. The average size of TiO2 was found to be 56.92 nm as measured from dynamic light scattering analysis. UV–visible spectrometry showed an absorbance of 0.13 (<1). The nanoparticles displayed UV light-responsive catalytic ability with a bandgap energy of 3.14 eV. Furthermore, atrazine was discovered using mass spectrometry, which revealed a clear and sharp peak at 173, 95, and 76 m/z, respectively, at collision energies of 16 and 24 eV. The photocatalytic activity of the TiO2 nanoparticles was examined for the degradation of atrazine. Overall, the obtained results displayed the great efficiency of TiO2 nanoparticles towards ultra-violet light, which was 92.56% at 100 mg of dosages, highlighting the great potential of the photocatalysis process for atrazine degradation. Furthermore, the process followed pseudo-first-order kinetics and the rate was seen to depend on catalyst loading.
CIRCULAR ECONOMY SUPPLY CHAIN FOR SUSTAINABLE DEVELOPMENT GOALS (SDGS): A REVIEW AND FUTURE OPPORTUNITIES
Authors: Ivan Kurniawan  , Yudi Fernando
Published: March 2023

The issue of sustainability has escalated over the years as the growing concern of world resources that have begun to deplete. Hence, the United Nations (UN) adopted the sustainability 2030 agenda with 17 sustainable development goals (SDGs) to pursue economic, environmental, and social objectives. One of the most prominent concepts to achieve sustainability is circular economy supply chain (CESC). The basic idea of CESC is a system that aims to eliminate waste and preserves natural resources by keeping materials in use and a regenerative natural system. Therefore, the purpose of this paper is to examine the connection between CESC and SDGs as well as the opportunities for research in the future. A systematic literature review on the CESC for SDGs is carried out. There is a significant increase in studies associated with the implementation of CESC to achieve SDGs. The results show that CESC contributes significantly to SDG 2, SDG 8, and SDG 12. Another finding is that technologies could assist CESC practices. CESC implementation for achieving SDGs is not only for big enterprises but also for small and medium enterprises (SMEs). Discussions related to social aspects are less often carried out than from economic and environmental aspects. Future opportunities have been identified for four industrial sectors: manufacturing, agriculture, waste management, and natural resources.
Transthyretin knockdown recapitulates the insulin-sensitizing effects of exercise and promotes skeletal muscle adaptation to exercise endurance

Published: March 2023

Liver transthyretin (TTR) synthesis and release are exacerbated in insulin-resistant states but are decreased by exercise training, in relation to the insulin-sensitizing effects of exercise. We hypothesized that TTR knockdown (TTR-KD) may mimic this exercise-induced metabolic improvement and skeletal muscle remodeling. Adeno-associated virus-mediated TTR-KD and control mice were trained for 8 weeks on treadmills. Their metabolism status and exercise capacity were investigated and then compared with sedentary controls. After treadmill training, the mice showed improved glucose and insulin tolerance, hepatic steatosis, and exercise endurance. Sedentary TTR-KD mice displayed metabolic improvements comparable to the improvements in trained mice. Both exercise training and TTR-KD promoted the oxidative myofiber compositions of MyHC I and MyHC IIa in the quadriceps and gastrocnemius skeletal muscles. Furthermore, training and TTR-KD had an additive effect on running performance, accompanied by substantial increases in oxidative myofiber composition, Ca2+-dependent Ca2+/calmodulin-dependent protein kinase II (CaMKII) activity, and the downstream expression of PGC1α as well as the unfolded protein response (UPR) segment of PERK-p-eIF2a pathway activity. Consistent with these findings, electrical pulse stimulation of an in vitro model of chronic exercise (with differentiated C2C12 myoblasts) showed that exogenous TTR protein was internalized and localized in the endoplasmic reticulum, where it disrupted Ca2+ dynamics; this led to decreases in intracellular Ca2+ concentration and downstream pathway activity. TTR-KD may function as an exercise/Ca2+-dependent CaMKII-PGC1α-UPR regulator that upregulates the oxidative myofiber composition of fast-type muscles; it appears to mimic the effect of exercise training on insulin sensitivity-related metabolic improvement and endurance capacity.

The functional versatility of the liver is paramount for organismal homeostasis. Adult liver functions are controlled by a tightly regulated transcription factor network including nuclear receptors (NRs), which orchestrate many aspects of hepatic physiology. NRs are transcription factors sensitive to extracellular cues such as hormones, lipids, xenobiotics, etc. and are modulated by intracellular signaling pathways. While liver functional zonation and adaptability to fluctuating conditions rely on a sophisticated cellular architecture, a comprehensive knowledge of NR functions within liver cell populations is still lacking. As a step toward the accurate mapping of NR functions in the liver, we characterized their levels of expression in the whole liver from C57Bl6/J male mice as a function of time and diet. Nr1d1 (Rev-erba), Nr1d2 (Rev-erbb), Nr1c2 (Pparb/d), and Nr1f3 (Rorg) exhibited a robust cyclical expression in ad libitum-fed mice which was, like most cyclically expressed NRs, reinforced upon time-restricted feeding. In a few instances, cyclical expression was lost or gained as a function of the feeding regimen. NR isoform expression was explored in purified hepatocytes, cholangiocytes, Kupffer cells, hepatic stellate cells, and liver sinusoidal cells. The expression of some NR isoforms, such as Nr1h4 (Fxra) and Nr1b1 (Rara) isoforms, was markedly restricted to a few cell types. Leveraging liver single-cell RNAseq studies yielded a zonation pattern of NRs in hepatocytes, liver sinusoidal cells, and stellate cells, establishing a link between NR subtissular localization and liver functional specialization. In summary, we provide here an up-to-date compendium of NR expression in mouse liver in space and time.

Published: March 2023

With the increased awareness of thermal insulation of buildings, the knowledge of thermal conductivity of non-structural materials applied for roughing, cladding or flooring has become more important. The objective of this study was to investigate the thermal conductivity of 31 different wood species originated from the region of Izmir in Turkey. Thermal conductivity of air dried boards was determined in accordance to ASTM 5334 standard which measures this property on the interior of wood rather than on the surface. Thermal conductivity varied from 0.090 to 0.197 W/mK. The highest thermal conductivity was obtained for oak and the lowest for Canadian poplar. A linear relation was obtained between wood density and thermal conductivity.

Authors: Wu Guofang , Gong Yingchun , Zhong Yong , Ren Haiqing
Published: March 2023

Compact tension specimens were used to determine the mode I (opening crack) fracture toughness of bamboo scrimber, a bio-based product for engineering applications. The influence of thickness and grain mode were investigated, and the extended finite element method (XFEM) was used to simulate the fracture behavior of bamboo scrimber. The results showed that all of the specimens failed in a brittle way. There were no significant differences in fracture toughness among specimens with different thicknesses; however, the grain mode did have a significant effect. The average fracture toughness KIC for T-L and R-L grain modes of bamboo scrimber were 54.32 MPa·mm1/2 and 47.91 MPa·mm1/2, respectively, where the letter “L” represents the longitudinal direction, “R” represents the stack direction, and “T” represents the flattened tangential direction. Based on the results, compact tension specimens with a thickness of 10 mm are recommended to measure the mode I fracture toughness of bamboo scrimber. Furthermore, XFEM was confirmed as a useful tool to investigate the fracture behavior of bamboo scrimber.

Authors: Xia Yuanyuan , Yang Guihua , Chen Jiachuan , Lin Zhaoyun
Published: March 2023

A cellulose nanocrystal (CNC) based dual-modification was explored as a means to achieve better film properties. Starch was mixed with 0.5 wt% CNC followed by oxidation with NaClO, then esterified with CNC and vinyl acetate. The dual-modified starch showed an increased degree of substitution, disrupted morphology, and decreased crystallinity. A remarkable catalytic effect of CNC was found with 0.3 wt% CNC in esterification, where the degree of substitution was 2.7 times higher than that of dual-modified starch without CNC. The best modifying condition was selected as 0.3 wt% CNC and 7.0 wt% vinyl acetate. The film generated from dual-modified starch, polyvinyl alcohol (PVOH), and glycerol generated a smooth surface and compact structure. Moreover, the films based on dual-modified starch had improved transparency, thermal stability, and tensile strength compared to that of native starch or oxidized starch. The highest tensile strength of film was obtained at 25.7 MPa with 30 wt% PVOH. The film showed the highest water resistance with a contact angle of 113°.
Effect of toilet tissue Paper on residential sewerage-line clogging
Authors: Elmas Gulnur Mertoglu , Ozturk Sultan Bekiroglu
Published: March 2023

Toilet paper is widely used in residences. The low biodegradability of toilet paper’s pulp fibers can cause residence sewer lines to clog, which may be due to some additives or the presence of nonwoven fiber products. In this study, the disintegration rate of toilet paper was compared against various physical factors of the toilet paper sheet. The samples were disintegrated in water at varying pH levels. In the manufacturing of toilet paper, there must be a balance between the desired softness and the necessary wet strength. Twelve commonly used brands of toilet paper were purchased locally. Physical factors of toilet paper samples such as degree of polymerization, thickness, grammage, and softness were determined. The samples were evaluated based on 9 variables using correlation and multivariate linear regression analyses. A strong positive relationship was found between the degree of disintegration of toilet tissue paper and its physical factors. These were the degree of polymerization, the grammage, thickness, and the softness. Additionally, the amount of polymers applied to toilet paper decreased the degree of softness and adversely affected the redispersion of fibers. Thus, this work supports the idea that toilet paper can contribute to clogging of residential sewerage lines.

Published: March 2023

Rubberwood, which can be regarded as a natural polymer composite, presents many difficulties in the process of material modification. In this study, a convenient method was developed to impart superhydrophobicity to the rubberwood surface. SiO2-PS composite film was formed on rubberwood surface by simple short-term impregnation. The obtained superhydrophobic rubberwood exhibited a water contact angle (WCA) of ~155.6° at room temperature. The superhydrophobic coating surface provides the abilities of self-cleaning and anti-bacteria for rubberwood. Combined with a small amount of 3-iodo-2-propyl-butyl carbamate (IPBC), the control effect of the four fungi reached 75% (Botryodiplodia theobromae), 100% (Trichoderma viride), 95% (Penicillium citrinum), and 100% (Aspergillus niger), respectively. The developed method herein features environment-friendly raw materials, facile processing, and large-scale fabrication. It provides a new solution for long- term timber protection processing.

Published: March 2023

According to the limit of detection (DL) presented in ISO 11929:2010, the International Organization for Standardization (ISO) abandoned the concept of minimum detectable amount (MDA) described in ISO 12790-1:2001. In this work we demonstrate and discuss how we calculate the detection limit for the determination of 210Pb by liquid scintillation counter (LSC) for the previously developed methodology and compare its results with the MDA value. The DL value found was 0.033 Bq/L instead of 0.032 Bq/L for MDA. The MDA and LD values ​​did not differ virtually, the results highlight that the main change between the two Standard is related to the definition approach.
Utility of thermographic evaluation in spinal cord stimulation therapy DTM workflow for thoracolumbar compression fracture and lumbar spinal canal stenosis
Authors: Maeda Hiroyuki
Published: March 2023

Among the orthopedic conditions that cause low back pain, many patients with thoracolumbar compression fractures and lumbar spinal canal stenosis caused by osteoporosis visit orthopedic surgeons. However, many patients do not respond to analgesics or nerve block injections, and many are at risk or unwilling to undergo surgery due to age or underlying disease. We believe that spinal cord stimulation therapy is a new treatment option for orthopedic low back and leg pain. We have performed spinal cord stimulation for chronic intractable pain in patients with thoracolumbar spine compression fractures and lumbar spinal canal stenosis who had lower limb pain and back pain. There are few reports of spinal cord stimulation therapy treatment by orthopedic surgeons. In many cases, medical medications and nerve blocks do not improve the pain, and surgical treatment may be performed. We evaluated whether minimally invasive spinal cord stimulation therapy for orthopedic diseases improves pain by altering blood flow to the lower extremities using thermography. Methods: Thermography and NRS of both lower extremities were measured before and after spinal cord stimulation therapy in 27 patients (15 women and 12 men) with back and leg pain due to thoracolumbar spine compression fracture and lumbar spinal canal stenosis. Results: Thermography showed an increase in body surface temperature of approximately 6°C. NRS showed an average improvement of 6.4. Discussion: Spinal cord stimulation therapy may improve blood flow in both lower limbs and lower back and leg pain, especially for back and leg pain caused by thoracolumbar vertebral compression fracture and lumbar spinal canal stenosis, among other orthopedic diseases. Thermography is likely to be useful as an evaluation tool.

Authors: Robsky Katherine O. , Chaisson Lelia H. , Naufal Fahd , Delgado-Barroso Pamela , Alvarez-Manzo Hector S. , Golub Jonathan E. , Shapiro Adrienne E. , Salazar-Austin Nicole
Published: March 2023

Context

Improving detection of pediatric tuberculosis (TB) is critical to reducing morbidity and mortality among children.

Objective

We conducted a systematic review to estimate the number of children needed to screen (NNS) to detect a single case of active TB using different active case finding (ACF) screening approaches and across different settings.

Data Sources

We searched 4 databases (PubMed, Embase, Scopus, and the Cochrane Library) for articles published from November 2010 to February 2020.

Study Selection

We included studies of TB ACF in children using symptom-based screening, clinical indicators, chest x-ray, and Xpert.

Data Extraction

We indirectly estimated the weighted mean NNS for a given modality, location, and population using the inverse of the weighted prevalence. We assessed risk of bias using a modified AXIS tool.

Results

We screened 27 221 titles and abstracts, of which we included 31 studies of ACF in children < 15 years old. Symptom-based screening was the most common screening modality (weighted mean NNS: 257 [range, 5–undefined], 19 studies). The weighted mean NNS was lower in both inpatient (216 [18–241]) and outpatient (67 [5–undefined]) settings (107 [5–undefined]) compared with community (1117 [28–5146]) and school settings (464 [118–665]). Risk of bias was low.

Limitations

Heterogeneity in the screening modalities and populations make it difficult to draw conclusions.

Conclusions

We identified a potential opportunity to increase TB detection by screening children presenting in health care settings. Pediatric TB case finding interventions should incorporate evidence-based interventions and local contextual information in an effort to detect as many children with TB as possible.

Published: March 2023

To develop a unified approach for the design of partially debonded strands in prestressed concrete highway bridge girders, a coordinated analytical and experimental investigation was conducted. This investigation examined amounts of partial debonding, distribution of partially debonded strands within the cross section, debonded lengths, locations and staggering of termination of debonded strands, confinement of debonded regions and their termination points, and the impact of adding nonprestressed reinforcement in the region of partial debonding. The results from testing full-scale I- and U-shaped girders indicate that partially debonding strands does not result in deleterious performance if adequate reinforcement is provided to resist the longitudinal tension due to bending and shear. Crack patterns and angles were not noticeably affected by the amount of debonding. Regardless of the debonding ratio, the maximum measured crack widths at the capacities predicted by the eighth edition of the American Association of State Highway and Transportation Officials’ AASHTO LRFD Bridge Design Specifications remained small. The requirements for debonded strands were revised significantly in the ninth edition of the AASTHO LRFD specifications based on the presented research.
Application of a NIRS Neuroimaging Method to Elucidate Neural Mechanisms of Exercise-cognition Interaction
Authors: Byun Kyeongho
Published: March 2023

PURPOSE: There is growing attention on a neuroimaging method called near-infrared spectroscopy (NIRS), which enables the monitoring of task-related regional hemodynamic responses in the brain. The basic principles and appropriate experimental conditions should be explained to eliminate potent contaminations caused by exercise itself and to summarize well-organized recent studies focusing on the interaction between exercise and cognition before applying this noninvasive neuroimaging method to various studies in the field of Exercise Science.METHODS: A comprehensive search of PubMed, Web of Science, and Google Scholar was performed to obtain recent studies examining the effects of exercise (or physical activity) on the executive functions localized in the prefrontal cortex by adopting the NIRS system.RESULTS: NIRS system enables exercise scientists to measure regional brain activity to investigate the effects of exercise on cognition and its neural substrates. Numerous studies have revealed that higher physical activity (or fitness) levels are related to better performance with increased prefrontal cortical activation during a task. Moreover, several longitudinal exercise intervention studies have demonstrated improved executive performance without increased task-related brain activation, particularly among older adults.CONCLUSIONS: NIRS neuroimaging studies support the notion that exercise has beneficial effects on executive function, with exerciseelicited functional changes in the prefrontal cortex.

Published: March 2023

PURPOSE: This study aimed to investigate the differences in the association between physical or mental problems and health maintenance methods.METHODS: This study used data from the 2019 Korea National Sports Participation Survey, conducted by the Ministry of Culture, Sports, and Tourism, as a nationally representative cross-sectional survey. This study included 7,863 participants (3,918 men, 3,945 women). A generalized linear model analysis was conducted and adjusted for sex, education, marital status, number of family members, children, monthly income, employment status, city type, residential type, and age. Additionally, we conducted a stratified analysis according to sex, monthly income, employment status, and city type.RESULTS: For the “regular sports activities” item, only women had a statistically positive result regardless of monthly income. For the “stop drinking and smoking” item, men had a statistically significant positive result regardless of monthly income and employment status.CONCLUSIONS: This study aimed to determine the differences in the relationship between physical or mental problems and health maintenance methods. The results confirm that the health maintenance method differs between men and women. Monthly income, employment status, and city type could also influence simultaneously. The health maintenance methods with differences between men and women were regular sports activities for monthly income and cessation of drinking and smoking for monthly income and employment status. Therefore, in future exercise physiology studies, the differences between men and women must be considered when selecting a method for maintaining health.
Comparison of Differences in Thigh Muscle Morphology and Function according to Post-anterior Cruciate Ligament Surgery Period
Authors: Jun Hyung-Pil , Chang Eunwook
Published: March 2023

PURPOSE: Quadriceps muscle weakness caused by muscle atrophy is a typical feature of individuals who undergo anterior cruciate ligament reconstruction. Although many studies have suggested an acceptable timing for returning to sports after anterior cruciate ligament reconstruction, there are still many controversies. Therefore, this study aimed to present an evidence-based recommendation for returning to sports after anterior cruciate ligament reconstruction by evaluating muscle size and function 9 months after the reconstruction.METHODS: Eighteen patients who underwent anterior cruciate ligament reconstruction were evaluated for quadricep thickness and isokinetic knee extension strength in both limbs. The Mann-Whitney U test was used to compare the differences 1) in thigh muscle thickness and isokinetic knee extension strength between the reconstructed limbs in “more than 9 months after surgery” and “less than 9 months after surgery” groups and 2) between the limb symmetry index of the two groups.RESULTS: The main findings were that the vastus medialis thickness and isokinetic knee extension strength for the reconstructed limbs were significantly greater in the more than 9 months after surgery group (vastus medialis: Z=12.00, p=.014; strength: Z=16.00, p=.034). The vastus medialis and vastus intermedius thicknesses in the more than 9 months after surgery group also showed a significant increase compared to those in the less than 9 months after surgery group (vastus medialis: Z=10.00, p=.006; vastus intermedius: Z= 10.00, p=.006).CONCLUSIONS: After anterior cruciate ligament reconstruction, selective muscle atrophy and weakness in the quadriceps muscles were observed. This study emphasizes the need for targeted early rehabilitation of specific quadriceps muscles to prevent muscle atrophy and weakness after anterior cruciate ligament reconstruction.

Published: March 2023

PURPOSE: This study aimed to verify the differences in shoulder range of motion (ROM) and dynamic stability in the upper extremities depending on the players’ ages and frequency of sports injuries in the shoulder joint.METHODS: A total of 519 volleyball players enrolled in the Korea Volleyball Association and Korean Volleyball Federation participated in this study. All participants answered questions about their experiences of sports-related shoulder injuries and were then categorized into shoulder-injured and non-injured groups. Shoulder ROM (flexion/extension and internal/external rotation) and upper quarter Y-balance (YBT-UQ) were tested by trained examiners. The YBT-UQ was normalized to the arm length (%AL) of the players.RESULTS: Among elementary and middle school players, the shoulder-injured group had lower internal rotation than the non-injured group. In addition, elementary school players with a history of shoulder injuries performed worse in the YBT-UQ test. Regardless of their history of shoulder injury, older patients tended to have decreased shoulder flexion and extension. In the injured group, younger players had lower internal rotation of the shoulder.CONCLUSIONS: These results showed that player age should be considered for rehabilitation to prevent shoulder sports-related injuries in volleyball players.

PURPOSE: The study aimed to investigate the effects of treadmill running and intraperitoneal vitamin D administration on the changes in skeletal muscle morphology and mitochondrial dynamics induced by a high-fat diet (HFD) in C57BL/6 mice.METHODS: Fifty 5-week-old C57BL/6 mice were randomly assigned to either standard chow (SC, n=10) or HFD (n=40), and the animals were maintained on each diet for 12 weeks. During the final 6 weeks on these diet, the HFD mice were further divided into four subgroups: HFD only (n=10), HFD plus treadmill running (HFD+EX, n=10), HFD plus vitamin D administration (HFD+VD, n=10), and HFD plus treadmill running plus vitamin D administration (HFD+VD+EX, n=10). The morphology and mitochondrial dynamics markers of the gastrocnemius were assessed with immunohistochemistry and western blot, respectively.RESULTS: HFD resulted in morphological alterations in the muscle, such as decreased myocyte cross-sectional area and increased extramyocyte space. However, the HFD-induced morphological alterations were reversed by the combination of treadmill running and vitamin D administration (HFD vs. HFD+VD+EX). Furthermore, the combined treatment of treadmill running and vitamin D improved mitochondrial dynamics signaling pathways, such as mitochondrial fusion, fission, mitophagy, and mitochondria-mediated skeletal muscle apoptosis.CONCLUSIONS: The findings of the study suggest that a combination of exercise and vitamin D supplementation might be an effective therapeutic strategy against HFD-induced morphological alterations and mitochondrial dysfunctions in skeletal muscle.
Confrontar o presente: a crise democrática a partir do setor de Direitos Humanos do MST
Authors: Efrem Filho Roberto
Published: March 2023

Resumo Neste ensaio etnográfico, busco perspectivar a crise democrática brasileira a partir do cotidiano do grupo de advogados e assessores jurídicos populares que integram o setor de Direitos Humanos do MST de Pernambuco, a que pertenço e cuja atuação se dá em contextos políticos intensa e historicamente marcados por violência e criminalização. Para tanto, tomo como ponto de partida dois acontecimentos de que tive notícia em 24 de abril de 2021: a prisão de um motorista de carro de som acusado de ferir a honra do presidente da República e incorrer num crime da Lei de Segurança Nacional; e as perseguições e ameaças de morte contra um sem-terra implicado em conflitos agrários na Mata Sul de Pernambuco. Com isso, pretendo divisar as ressonâncias do bolsonarismo nesses casos, os constrangimentos de Estado neles engendrados e as contradições de nossa experiência democrática, que atualiza imagens do passado ao tempo que demanda o confronto com seu presente.
La socialización de la lectura y la escritura: fandom, redes y visibilidad editorial
Authors: García José Antonio Cordón , Rico María Muñoz
Published: March 2023

Resumen: La lectura ha experimentado cambios significativos en la última década, caracterizados por la modificación del comportamiento del público lector, así como por las formas de acceso y consumo. Uno de los aspectos más significativos ha sido el papel cada vez más activo que han recibido los lectores en el proceso de recepción, cobrando un mayor protagonismo gracias a las posibilidades de intervención en forma de comentarios, recomendaciones, e intercambio de información de diversa naturaleza entre ellos. Pero también a su organización en redes de intereses a partir de un texto o un autor, constituyendo grupos de fan, que no sólo dialogan y participan y promueven actos de promoción y reivindicación de tramas y escenarios, sino que alimentan el corpus mediante creaciones propias o traducciones anticipadas. Con todo ello se incrementan los niveles de visibilidad de las obras y autores, favoreciendo su difusión y coadyuvando indirectamente a la actividad editorial, que ha modificado parte de sus tareas promocionales amparada en estos nuevos escenarios. Se analiza en el artículo la incidencia de estos fenómenos desde el punto de vista de las métricas en bases de datos y desde el influjo en la actividad creativa y editorial.
El storytelling como recurso didáctico-comunicativo para fomentar la lectura
Authors: García Álvaro Pérez , Rodríguez Ignacio Sacaluga
Published: March 2023

Resumen su imaginación y su función cerebral es, en la actualidad, un caballo de batalla tanto en la escuela como en la familia. Buscar recursos y herramientas motivadoras para fomentar el hábito lector es fundamental, y el storytelling es un interesante recurso. Nuestro objetivo es analizar las experiencias y buenas prácticas de utilización del storytelling para fomentar el hábito lector en niños y adolescentes que se están llevando a cabo en España y otros países, para valorar su implantación como estrategia didáctica. Se utilizó una metodología metodología cualitativa, basada en el método analítico-descriptivo. A pesar de que el storytelling es un recurso cada vez más utilizado en el ámbito educativo, aún son escasas las experiencias encontradas sobre su uso para fomentar la lectura en niños y adolescentes. Concluimos que el storytelling puede ser un recurso didáctico y creativo muy motivador para fomentar el hábito de la lectura, tanto en niños como en adolescentes, dado su componente multimedia y su capacidad de contar historias.
Reading practices in the network of trainee teachers in Primary Education
Authors: Pérez Magdalena López , Retamar Guadalupe de la Maya
Published: March 2023

Abstract The increased presence of adolescents and young people on the Internet has led to an interest in analysing their reading and multimodal practices, which sometimes involve the creation of spaces for reading socialisation in this context and the development of vernacular practices on the Internet ( CASSANY, 2012). In this paper, we want to explore this question in greater depth, considering their reading practices on the web and the knowledge that teacher trainees in Primary Education at the University of Extremadura have about the new genres developed in this media context. For this purpose, an ad hoc questionnaire was designed in which the students reported on their reading habits and practices. The results show a scarce knowledge of the genres mentioned and very little consolidated reading habits, which makes it necessary to carry out specific work to reinforce this habit and their knowledge of the different practices.

Authors: FİRİDİN Beran , ALTUN Nurver
Published: March 2023

Thaumetopoea pityocampa (Denis & Schiffermüller, 1775) (Lepidoptera:Notodontidae ) is the most important defoliating insect for several pine species and cedars. In this study, body nutrient composition of T. pityocampa larvae were analyzed under feeding inhibition caused by natural chemical agents. In no-choice assays, larvae were fed ponderosa pine needles treated with oleic acid and chlorogenic acid solutions, respectively, at each of four concentrations, 0%, 25%, 50% and 75%. The neetles were as given to separate test groups. At the end of feeding experiments, antifeedant index (AFI) was calculated for each solutions with different concentrations. Then, rates of protein, lipid, glycogen and water of larvae were calculated for control and test groups. It was determined that there had been a strong relation between concentrations of solution and AFI values regarding oleic acid (r= 0.998, P < 0.05). However, there was no significant relationship between concentrations of solution and AFI values regarding chlorogenic acid (r= 0.663, P > 0.5). The most remarkable finding was a sharp decline in the level of larval glycogen during starvation period in accordance with rising concentrations of both oleic and chlorogenic acid in its food. The glycogen level of the larvae was also affected by both chemical applications
Parameter Estimation of Induction Motors using Hybrid GWO-CS Algorithm
Authors: EMİROGLU Selcuk
Published: March 2023

This study investigates a hybrid algorithm between Grey Wolf Optimization (GWO) and Cuckoo Search (CS) algorithms to find the parameters of induction motors. The parameters of the induction motor have been estimated by using the data supplied by the manufacturer. The problem for parameter estimation of the induction motor is formulated as an optimization problem. Then, the optimization problem is solved by using GWO and hybrid algorithm based on GWO and CS algorithms for the estimation of induction motor parameters. Numerical results show that both algorithms are capable of solving the optimization problem for finding the parameters of induction motor. Also, two algorithms and other algorithms such as Differential Evolution (DE), Genetic Algorithm (GA), Particle Swarm Optimization (PSO), Shuffled Frog-Leaping Algorithm (SFLA), and Modified Shuffled Frog-Leaping Algorithm (MSFLA) are compared for the problem. The results show that the hybrid GWO-CS algorithm gives a smaller objective value and closer torque value to the manufacturer’s data than the GWO algorithm and several algorithms for motor 1. Hybrid GWO-CS algorithm gives nearly the same results with GWO algorithm for motor 2.

Published: March 2023

This study reports the condition factor, length-weight, and length-length relationships in females, males, and all samples of Mullus barbatus inhabiting Mersin Bay. A total of 152 individuals were sampled. The mean weight (W) was 18.01 ± 0.573 g, and the mean total length (TL), fork length (FL), and standard length (SL) were 12.0 ± 0.094 cm, 11.0 ± 0,086 cm, and 9.9 ± 0.080 cm for all M. barbatus, respectively. The total length-weight relationship was determined as W=0.0033TL3.444 (R2=0.90). The b value was calculated as 3.444 and it showed positive allometric growth for all M. barbatus inhabiting Mersin Bay. The LLRs were calculated as TL=1.0706FL+0.1386 (R2=0.95), TL=1.1634SL+0.371 (R2=0.97), and FL=1.0541SL+0.543 (R2=0.96) for all individuals, respectively. The mean value of the condition factor was calculated as 1.00 ± 0,0093 for all M. barbatus samples. The values of the condition factor in M. barbatus ranged from 0.740 to 1.274. There are few studies about M. barbatus population inhabiting Mersin Bay. In this study, condition factor, length-weight and length-length relationships were determined for M. barbatus inhabiting this region (the northeastern Mediterranean Sea).
