Published: March 2023

Rice straw and corn straw were selected as raw materials to prepare biocharby anoxic carbonization and the biochar was loaded on the surface with FeCl3, MnCl2 and Fe(NO3)3 & KMnO4, respectively, and then two types of straw biochar and six types of modified biochar were prepared. FT-IR, SEM, and XRD were used to characterize and analyze the physical and chemical properties of the biochar. The adsorption kinetics and adsorption isothermal tests of Cd2+ ions in aqueous solution were carried out. The results showed that modified biochars attached more active sites and surface group, especially iron-manganese-modified biochar (FMBC1, FMBC2). The kinetic adsorption tests showed that the adsorption process of eight kinds of biochar all conformed to the quasi-second-order kinetic equation, and chemisorption maybe dominated the adsorption process. The adsorption isothermal test showed that the adsorption process of Cd2+ ions by FeCl3-modified biochar (FBC1, FBC2) and Fe(NO3)3 & KMnO4-modified biochar (FMBC1, FMBC2) conforms to the Freundlich model, and the adsorption process of Cd2+ ions by MnCl2-modified biochar (MBC1, MBC2) conforms to Langmuir model. Compared with other kinds of biochar, the KF value of Fe(NO3)3 & KMnO4-modified biochar of rice straw biochar (FMBC1) was the largest, reached 18.602 L·mg−1, and its 1/n value was the smallest, it reached 0.474, indicating that the adsorption effect on Cd2+ of FMBC1 was the best.

Published: March 2023

The concentrated photovoltaic/thermal system (CPVT) adopting spectral beam splitting is a promising field of solar energy research. However, the thermo-electric properties of fluid-based CPVT collectors, which depend strongly on the non-uniform concentrated energy flux, remain unclear. This study aims to fill the gap and explore the thermo-electric properties of fluid-based CPVT collectors under non-uniform energy flux based on the finite volume method (FVM) with the Monte Carlo Ray-Trace (MCRT) method. The actual solar flux distribution on the receiver surface is obtained using Tracepro software. Then, the realistic non-uniform energy flux was employed in ANSYS Workbench 2022R1 software as a boundary condition to increase the accuracy of the CFD modeling of the system. The model is validated by comparing the results of the reference data. Moreover, the impact of uniform and non-uniform energy flux on the PV cell temperature is analyzed. In addition, the effects of mass flow rate on the electrical and thermal performance of the system are investigated. The results show that the PVT hybrid system has high conversion efficiency, with a total efficiency of more than 50%. Notably, the extreme non-uniformity of the solar-concentrated energy flux can result in local overheating of the PV cell, which may lead to irreversible damage.

Coastal salt-affected soils account for a large area all around the world. Soil salinity and pH are two important parameters affecting soil quality. Investigating the correlation of electrical conductivity (EC) and pH at different soil depths in saline soil was useful for quickly assessing the saline–alkaline characteristics. During the natural desalination process in the field area of reclaimed lands, the phenomena of pH increase and nitrogen accumulation may occur. A field sampling experiment was conducted in slightly saline soil affected by natural desalination and newly reclaimed heavily saline soil. A series of soil–water ratio extracts consisting of 1:2.5, 1:5, 1:10, 1:20, and 1:40 was designed to measure the EC and pH for simulating the saline–alkaline characteristics during the soil desalination process. Meanwhile, for reasonable utilization of the naturally ameliorated slightly saline soil which consists of a high content of nitrogen, a plastic mulching (PM) accompanied with nitrogen (N) fertilizer addition experiment in maize cultivation plots was designed. Results showed that a significant correlation of EC and/or pH existed in all ratios of soil extracts, and the slightly saline soil had a higher nitrogen content (1.06 g kg−1). The EC was negatively correlated with pH at a depth of 0~100 cm in the coastal saline soil, which indicated the increase of pH value and alkalization during its natural desalination. Furthermore, PM treatments showed no significant difference with N treatments in soil bulk density and soil water content in the slightly saline soil. The PM and N treatments obtained similar grain yield, which was between 6.2 and 6.5 t ha−1. The soil salinity decreased in all treatments and the harvest index was largest in PM treated plots. Our study was beneficial for rapidly monitoring saline–alkaline characteristics and sustainable utilization of coastal saline soil resources. In addition, we should focus far more on pH improvement during the desalination process and rational utilization of chemical fertilizer for obtaining sustainable benefits in the coastal saline soil.

Introduction: This study aims to assess the palliative care nursing (PCN) knowledge and attitude of nursing students toward end-of-life care (EoLC) after completing the multi-methods PCN courses. Methods: A quasi-experimental study with a pre-and post-palliative survey was conducted. One hundred and sixty five nursing students from a faculty of nursing in Indonesia were enrolled, and knowledge and attitude were assessed using the palliative care quiz for nurses (PCQN) and the Frommelt Attitude Toward Care of the Dying and Death (FATCOD). Paired t-test and ANOVA were applied in this study. Results: After being involved in the PCN course, the mean score of PCN knowledge of the students increased significantly (p < 0.001). According to sub-domain analysis, the knowledge increased significantly in pain and symptom management (p < 0.001) and not significantly in the domains of theory and principle of the palliative, psychosocial, and spiritual care (p = 0.053; p = 0.080). Moreover, students’ attitude toward EoLC also increased significantly (p < 0.001), and positive attitudes increased from 75.6% to 91.5%. According to the ANOVA test, knowledge in two different groups (witnessed dying people and GPA) is not statistically meaningful (FWDP (1158) = 0.817, p = 0.367; FGPA (2.158) = 1.143, p = 0.322). Similarly, attitudes toward EoLC in two different groups are not statistically meaningful (FWD (1158) = 0.971. p = 0.326, FGPA (1157) = 1.278, p = 0.281). Conclusion: PCN courses with multi-method learning and teaching are effective to increase PCN knowledge, particularly in pain and symptom management knowledge, and also effective in increasing the positive attitudes toward EoLC.

Published: March 2023

In a response to the appeal for securing the rice production efficiency to achieve the United Nations Sustainable Development Goals, we adopted a geographic detector model to investigate the spatiotemporal evolution trajectory and driving forces of the rice production in the world’s largest rice-producing country, China. We have analyzed the spatiotemporal evolution features and aggregation patterns of county rice production efficiency based on panel data of 122 counties in Hunan Province, one of the main grain production provinces in China, from 2006 to 2018. Our findings indicate: (1) Hunan Province’s rice production in three counties (i.e., Taoyuan, Liling, and Anren) showed the highest efficiency; there were pronounced regional variances in rice productivity which results in a sharp and rapid shrink of the range of rice productivity, (2) financial investments in agriculture, forestry, and water resources, as well as per capita disposable income of farmers, were the main determinants of the spatiotemporal variation in rice production efficiency, (3) the spatiotemporal divergence of rice production efficiency at the province level was U-shapedly, influenced by the share of secondary industry in GDP; the southern Hunan region received the biggest contribution from farmers in terms of disposable income per person at the regional level. Overall, theoretically, this study offers fresh evidence for regional optimization of rice and other grain production from a novel integrative approach of the geospatial and the land resource preservation. Practically, it provides feasible guidance for the high-quality development of grain production in China, which may also help eradicate hunger and attain sustainable grain production all over the world.

Zika virus (ZIKV), a mosquito-borne pathogen, is an emerging arbovirus associated with sporadic symptomatic cases of great medical concern, particularly among pregnant women and newborns affected with neurological disorders. Serological diagnosis of ZIKV infection is still an unmet challenge due to the co-circulation of the dengue virus, which shares extensive sequence conservation of structural proteins leading to the generation of cross-reactive antibodies. In this study, we aimed to obtain tools for the development of improved serological tests for the detection of ZIKV infection. Polyclonal sera (pAb) and a monoclonal antibody (mAb 2F2) against a recombinant form of the ZIKV nonstructural protein 1 (NS1) allowed the identification of linear peptide epitopes of the NS1 protein. Based on these findings, six chemically synthesized peptides were tested both in dot blot and ELISA assays using convalescent sera collected from ZIKV-infected patients. Two of these peptides specifically detected the presence of ZIKV antibodies and proved to be candidates for the detection of ZIKV-infected subjects. The availability of these tools opens perspectives for the development of NS1-based serological tests with enhanced sensitivity regarding other flaviviruses.

The teaching hospital of the Faculty of Veterinary Medicine at the University of Lisbon hosts a Biological Isolation and Containment Unit (BICU) for the hospitalization of both confirmed and suspected animals of an infectious disease. This study targets the BICU dog population to identify and characterize the most frequent infectious diseases recorded in a 7-year period. Several epidemiologic factors were analyzed for their significance to triage infected cases. During the study period, 534 dogs were admitted, of which 263 (49.3%) had a confirmed infectious disease diagnosis: parvovirosis (49.4%; n = 130); leptospirosis (21.7%; n = 57); multidrug-resistant (MDR) bacterial infection; (10.6%; n = 28), and canine distemper (9.9%; n = 26). Several potential risk factors for these diseases were identified: age under 2 years old (p < 0.001), incomplete vaccination for parvovirosis (p < 0.001), age ≥ 10 years old (p < 0.001), and the presence of concomitant disorders for MDR-infected cases (p = 0.03). Logistic regression models were constructed to classify cases and controls. The sensitivity and specificity estimates were very high (>0.83) for parvovirosis, MDR, and distemper infections. A lower sensitivity (0.77) was obtained for identifying cases with leptospirosis. In conclusion, infectious diseases are frequent, hence, it is essential to decrease their occurrence through effective preventive measures such as vaccination. The constructed logistic models can also help in triaging admitted dogs with a potential infectious disease.

The management of livestock affected by fire often comes down to two options: euthanasia or slaughtering. However, the therapeutic approach can be attempted for high-value cattle. The aim of a primary assessment is to identify signs of smoke inhalation injuries, cardiovascular impairment and shock and to determine the severity and extent of burn injuries. Full-thickness burns covering 40% or more of the body are highly unfavorable prognostic factors and are usually fatal. Moreover, it can take several days for the burns to appear in their full extent, leaving the prognosis uncertain. In this case report, the clinical findings, treatment and outcome of two burnt Holstein heifers are described. Daily wound care required cleaning, the removal of eschars and the application of topical antibacterial agents for seven months in order to discharge one heifer. The topical use of honey with a solution of povidone–iodine proved to be affordable and successful, with no residue risks. The other heifer was more severely wounded, and despite the administration of fluid therapy, pain management, anti-oxidants and anti-microbials, after initial stabilization, the animal’s condition worsened, leading to euthanasia. This confirms that the treatment of burnt cattle is possible but challenging due to the late onset of multi-organ failure.

Miocardite é uma doença inflamatória do miocárdio. A Insuficiência Cardíaca é uma síndrome clínica complexa, situação em que o coração é incapaz de bombear sangue eficientemente. Objetivo: Analisar a mortalidade por miocardite e insuficiência cardíaca no período de 2018 a 2021 no Brasil. Método: Estudo ecológico de séries temporais. A mortalidade foi calculada e por faixa etária. Para estimar a tendência, foi realizado regressão linear, com dados do Sistema de Informações. Resultado: Os resultados demonstraram que em ambas doenças, os óbitos ocorreram mais em pacientes após os 80 anos. Os óbitos por miocardite em 2018 aumentaram de 85 para 132 em 2021 e de insuficiência cardíaca de 26.382 para 31.580. Ao avaliar pela idade, os pacientes com idade entre 20 e 29 anos tiveram maior quantidade de óbitos por miocardite, mas não por insuficiência cardíaca. Conclusão: Em miocardite, aos 50 anos tiveram aumento de óbito em 2021, sendo que nos anos anteriores a 2021 não vinham apresentando números significativos nessa idade, levando a interrogar algo que tivesse acontecido no ano de 2020 ou 2021 que gerasse maior óbito por miocardite em pacientes mais jovens que o habitual, como por exemplo, a possível infecção pelo Coronavírus Humano. Em relação a Insuficiência Cardíaca, o aumento da mortalidade de 2018 para 2019 foi de 2,2%, 2,6% de 2019 para 2020 e de 2020 para 2021 a quantidade subiu para 14,0%. Através disso, mostra que algo ocorreu nesse período de 2020 e 2021 para justificar o aumento de óbitos.

Os seres humanos têm milhões de microrganismos em nossos corpos em simbiose, 20 milhões de genes microbianos foram identificados. A acne afeta entre 85% a 90% da população mundial que tem dietas ocidentais, isso por sua vez acarreta psicologicamente, doenças como depressão, ansiedade, etc. As bases etiológicas da doença são dadas pela família Cutibacterium acnes (Propionibacterium), mas o mecanismo não está tão claro. Atualmente, há evidências indicando que o Staphylococcus epidermidis da pele e também do microbioma intestinal estão envolvidos. Portanto, neste estudo, buscou-se o papel do microbioma intestinal e facial no desenvolvimento da acne vulgaris, bem como a atualização do mecanismo com base nos artigos mais recentes. Como conclusão e achados relevantes, foi visto que a inflamação da acne é dependente da homeostase intestinal, portanto o uso de probióticos reduz significativamente a inflamação das lesões de acne, além disso, os resultados dos tratamentos podem ser vistos após 2 semanas. Ademais, o uso de antibióticos deve ser evitado, pois reduzem o processo de cicatrização das lesões.

Unraveling the exact nature of nonequilibrium and correlated interactions is paramount for continued progress in many areas of condensed matter science. Such insight is a prerequisite to develop an engineered approach for smart materials with targeted properties designed to address standing needs such as efficient light harvesting, energy storage, or information processing. For this goal, it is critical to unravel the dynamics of the energy conversion processes between carriers in the earliest time scales of the excitation dynamics. We discuss the implementation and benefits of attosecond soft x-ray core-level spectroscopy up to photon energies of 600 eV for measurements in solid-state systems. In particular, we examine how the pairing between coherent spectral coverage and temporal resolution provides a powerful new insight into the quantum dynamic interactions that determine the macroscopic electronic and optical response. We highlight the different building blocks of the methodology and point out the important aspects for its application from condensed matter studies to materials as thin as 25 nm. Furthermore, we discuss the technological developments in the field of tabletop attosecond soft x-ray sources with time-resolved measurements at the near and extended edge simultaneously and investigate the exciting prospective of extending such technique to the study of 2-dimensional materials.

Published: March 2023

Com a alta demanda na produção de alimentos, a agropecuária e a agroindústria têm produzido grandes quantidades de resíduos. Os sistemas de criação da maricultura (comercial ou de bancos naturais) e avicultura comercial também são um dos responsáveis por esta alta demanda. Destarte o objetivo deste artigo foi realizar caracterização química e física de resíduos de conchas de ostras (RCOs), conchas de mexilhão (RCM) e cascas de ovos de galinha (COv). Os resíduos foram coletados em três municípios da Ilha do Maranhão que, após lavagem e secagem, foram submetidos a três ensaios analíticos: potencial hidrogeniônico (pH), verificação de carbonato de cálcio e quantificação do CaCO3 e Ca. Dentre os resíduos analisados, RCOs obtiveram valor médio superior de pH (9,5), com RCOv (9,18) e RCM (9,04) sucessivamente. RCOs apresentou maior porcentagem de cálcio e carbonato de cálcio dentre todos os resíduos investigados. Os resíduos apresentaram bandas que os caracterizam junto a aragonita e calcita. As análises realizadas indicam forte possibilidades dos resíduos serem utilizados como promotores de correção em solos naturalmente ácidos ou acidificados pelo uso de fertilizantes sintéticos, contudo mais pesquisas necessitam ser realizadas.

Authors: Can Hediye , Hiğde Emrah
Published: March 2023

Teachers’ intention to adopt and implement curriculum reform is an important matter for success in achieving standards for education. Science-Technology-Engineering-Mathematics practices advocated in the current curriculum. In this research pre-service math and science teachers’ intentions to implement STEM activities are investigated through the general framework of Theory of Reasoned Action. The questionnaires are formed by the researchers with the interviews and literature related to the theory. 260 pre-service math and science teachers from a state university in Turkey engaged in the research. The reliability and validity indexes of the questionnaires had evidence for the usability of the instruments. According to the results of the study, pre-service math and science teachers’ attitudes towards STEM activities, perceived behavioral control and subjective norms had significant contribution to their intentions to practice STEM in their classrooms. Behavioral beliefs including perceived behavioral expectancy and perceived behavioral values were effective for explaining pre-service teachers’ attitudes toward STEM. Subjective norms were significantly predicted by descriptive norms while injunctive norms did not significantly contribute to their formation. Perceived behavioral control is shaped by perceived difficulties rather than perceived behavioral convenience for STEM. Overall, the theory is effective and suitable in explaining pre-service teachers’ STEM intentions and pre-service teachers had high intention scores for implementing STEM in their classrooms. Further research may concentrate on improving in-service and pre-service teachers’ perceptions via effective implementations related to STEM both for their professional development and their students’ development.

Published: March 2023

Although the benefits of music have been known for many years, research on children’s educational achievements has intensified, especially recently. Self-concept is an essential criterion of success in education,known as an individual’s ideas and thoughts about himself are related to children’s behaviors and concrete characteristics. Self-concept is a concept that can be developed with education. The aim of this study, in which the self-concepts of 12-13-year-old instrument-playing students were tested, is to draw attention to the role of musical instrument education in the development of self-concept. The research was conducted with 7th-grade students studying in a public school in Ankara. The research results, which were applied to the students who played and did not play the instrument, were evaluated with the statistical program. As a result of the research, although there was no statistically significant result in the self-concept scores related to the time to start learning the instrument, it was concluded that students who play instruments and those who want to play have higher than others. In addition, it is anticipated that further long-term studies are required to monitor how the self-concept scores of children who play instruments develop over time.

Pathogenetically substantiated psychotherapeutic targets of adjustment disorders were developed in young people of internally displaced persons. 105 patients with adjustment disorders aged 18-25 years were examined with studying their clinical-psychopathological and pathopsychological features. The main group consisted of 59 internally displaced persons from the Anti-Terrorist Operation Zone, the control group consisted of 46 permanent residents of Kharkiv. According to the leading strategy of overcoming stress, 3 variants of adjustment disorders were identified in the surveyed young people: avoidance (in 35.9 % persons from main group and in 27.3 % persons from the control group), obsession (in 29.8 % and 36.9 % persons), phobias (in 34.3 % and 35.8 % persons). There are three directions of psychotherapeutic influence on clinical and pathopsychological manifestations of adjustment disorders: I direction is to manifestations of distress, depression and anxiety with phobic avoidance; II direction is to manifestations of obsession and avoidance; III direction is to manifestations of disorientation in the surroundings. Targets of psychotherapy of adjustment disorders in young internally displaced persons have been developed: clinical-psychopathological (anxiety in unusual situations, disorganization in actions, high level of reactive anxiety, subdepressive state, anti-vital experiences) and personal (low activity, selective communication, short-term anxiety, inability to fully disconnect from troubles and everyday problems).

Algorithmic Futures: An analysis of teacher professional digital competence frameworks through an algorithm literacy lens
Authors: Moylan Rachel , Code Jillianne
Published: March 2023

Algorithmic systems shape every aspect of our daily lives and impact our perceptions of the world. The ubiquity and profound impact of algorithms mean that algorithm literacy – awareness and knowledge of algorithm use, and the ability to evaluate algorithms critically and exercise agency when engaging with algorithmic systems – is a vital competence for navigating life in the 21st century. Professional digital competence (PDC) frameworks for teachers include technological, pedagogical, and social competence areas and are intended to illustrate the necessary knowledge, skills, and attitudes for digitally competent teachers. Using document analysis, we undertook a systematised review and evaluation of selected PDC frameworks through the lens of algorithm literacy. This analysis demonstrated that although some aspects of algorithm literacy could be inferred within the PDC frameworks analysed, there is a need for further explicit integration. Just as the DigComp framework for citizens has been updated to recognise the vital importance of understanding algorithmic systems' impact, so should PDC frameworks be revised. Recommendations are provided for incorporating understandings of algorithmic governance and bias and ensuring digital Bildung development in PDC frameworks. Implications for teacher education programs are also discussed.

Authors: Araújo Santos Lázaro , Cordeiro Rogério Soares , Boccardo Lilian
Published: March 2023

O relato aqui descrito é produto de debates, discussões e leituras realizadas na disciplina Docência no Ensino Superior, ofertada pelo Programa de Pós Graduação em Educação Científica e Formação de Professores, da Universidade Estadual do Sudoeste da Bahia (UESB), Campus Jequié, interior do estado. Este texto apresenta como se deram as abordagens do ‘ser docente’ na educação superior, enfatizando a construção da universidade brasileira enquanto instituição, os saberes necessários para docência no ensino superior, os desafios encontrados e a necessidade de continuarmos, mesmo frente às mazelas que a atual conjectura sócio-político-econômica submete o docente. Assim, ratificamos a urgência em se debater tais questões na pós-graduação, dado que os estudantes desse nível educacional estão se preparando, na sua maioria, para lidar com essa realidade. Portanto, sublinhamos a necessidade da inserção de disciplinas que possuam como base dos seus objetivos essas discussões, a fim de que sejam preparados profissionais críticos, autônomos e capazes de modificar a realidade na qual estão inseridos e/ou na qual se inserirão.
ABSTRACT
The report described here is the product of debates, discussions and readings carried out in the course Teaching in Graduation courses, offered by the Graduate Program in Scientific Education and Teacher Training, at the Universidade Estadual do Sudoeste da Bahia (UESB), Campus Jequié, in the interior of Bahia State. This paper aims to present how the approaches of 'being a teacher' in Graduate Education took place, emphasizing the construction of: Brazilian University as an institution, necessary knowledge for teaching in Graduate courses, major challenges, and the need to continue even in the face of the ills that the current socio-political-economic conjecture submits professors. Thus, we confirm the urgency of debating such issues in graduate studies, since students at this educational level are preparing themselves to deal with that reality. Therefore, we emphasize the need to insert subjects that have these discussions as the basis of their objectives, in order to prepare critical, autonomous professionals who are capable of modifying the reality in which they are inserted and/or in which they will be inserted.

Cubicle is an electrical device that functions as a breaker, protector, connector, controller, and divider of the power system electricity from a power source and reduce sparks when connecting. One of the problems that occur in medium voltage cubicles is the presence of corona. Corona phenomena at cubicle terminations can trigger disturbances such as a decrease in insulation quality, power loss and a significant increase in harmonic distortion. Based on previous research, the solution to minimize the occurrence of corona is to optimize the temperature and humidity of the cubicle. Many of the previous studies examined the control of cubicle temperature and humidity using fans and heaters, but the temperature and humidity had not yet reached a stable and optimal point. In this study, raised a problem regarding the optimization of temperature and humidity in cubicles using the fuzzy method to stabilize the performance of medium voltage cells. In this study, it was found that the fuzzy method in this prototype was able to stabilize the panel humidity at 55% RH and stabilize the panel room temperature at 31.5 o C. Thus, it is hoped that a stable and optimal temperature and humidity can minimize the occurrence of corona. The use of HMI/SCADA based applications can facilitate the ability of the user (operator) to monitor several available parameters and manually control the operation of the panel (on/off).
