Published: May 2023

ABSTRACT The application of silicon (Si) represents one of the alternatives that can be used to mitigate the deleterious effects caused by salinity on plants in fertigated cultivation. The objective was to evaluate the effect of different levels of water salinity, associated with the use of sodium silicate on the production parameters and nutrient levels in the leaf and stem of mini watermelon in a protected environment. To conduct the experiment, a randomized block design was adopted, in a 6 x 2 factorial scheme, with 4 repetitions, with six levels of irrigation water salinity (1.05; 2.12; 3.26; 4.41; 5.91 and 7.32 dS m-1) and two types of Si application: without Si and in foliar solution. The following parameters were evaluated: plant height, stem diameter, number of leaves, leaf and stem fresh and dry mass; biometric variables and total soluble solids content in the fruits; and nutrient contents in leaves and stem. The use of Si associated with fertigation with different salinity levels promoted a positive response for peel thickness, ºBrix, fresh and dry mass of leaves, and Si accumulation in leaves and stem. Salinity alone promoted an increase in pulp weight, ºBrix of the fruits and potassium content in the stem, besides increasing the manganese content and inhibiting the zinc content in the leaves. There was a significant interaction for the manganese content in the stem, with a positive response in the absence of foliar-applied Si and a negative response in the presence of foliar-applied Si under different levels of salinity.

Published: May 2023

ABSTRACT Due to the frequent occurrence of extreme hydrological events in the South American rivers, this work aims to develop a hydrological monitoring platform open to the public, with a wide and intuitive access, using resources of an online geographic information system, in order to contribute to a better understanding of the behavior of these natural disasters. SARDIM (South America River DIscharge Monitor) has been developed using programming resources in languages such as Python and JavaScript. The data of the platform are derived from results of a continental scale hydrological simulation model (MGB - South America) that uses, among other information, precipitation data from the GPM (Global Precipitation Measurement) mission and from the MSWEP (Multi-Source Weighted Ensemble Precipitation) product. After a statistical analysis of the model results, the platform is updated daily and operationally, with new data on the flow duration and the return period of river flows, allowing the identification, monitoring and evaluation of the intensity of extreme hydrological events in South America.

Published: May 2023

Abstract The present experiment was conducted to determine the effect chemical fertilization rates and foliar application of plant growth regulators PGRs (Kinetin or Napthaleneacetic Acid (NAA) and their interactions on growth, flowering, chemical composition of Ervatamia coronaria plants. The plants were fertilized monthly with NPK at the rate of 2, 4 and 6 g pot-1, in addition to the control plants. Plants received the fertilization treatments were sprayed monthly with either Kinetin or NAA at 50, 100 ppm for each one, while the control plants sprayed with tap water. As general, the results indicated that within each level of fertilizer treatments, treating plants with different concentrations of PGRs (Kinetin or NAA) resulted in significant increase in tested vegetative growth (in terms of plant height, number of branches plant-1, leaf area, number of leaves plant-1, stem diameter, root length, fresh and dry weights of leaves, stems and roots), flowering parameters (Viz number of flowers/ plant, fresh and dry weights of flowers), chlorophylls content, total carbohydrates, N, P , K%, total indoles and total phenols, gibberellins, auxins and cytokinins compared to control, with superiority of NAA particularly the highest concentrations (100 ppm) . Under the same level of PGRs raising the fertilization rate caused a gradual and significant increase in all tested parameters compared to control. Based on the results, it can be recommended that for the highest quality growth and flowering parameters of Ervatamia coronaria, the plants could be sprayed with NAA at 100 ppm combined with 6 g pot-1 NPK.
Selection process in ornamental plant breeding
Authors: Bugallo Verónica , Facciuto Gabriela
Published: May 2023

Abstract The selection is a process in which the best genotypes are chosen according to the desired characteristics for the specific use of the plant. Novelty, health, particular characteristics of each market and, increasingly, the low environmental impact of its production, are valued. One of the most questionable points in the selection of ornamental plants is the fact that beauty is subjective. To reduce subjectivity, breeders have chosen to delimit the selection criteria previously, generating a ranking and assigning values to each of the characters for the new cultivar. The selection criteria and traits to be evaluated depend on the use for which the crop is intended: cut flowers and foliage, pot plants, and landscape plants. In addition, the selection of functional plants (green walls and curtains, green roofs and ecological function plants) have their own criteria.

Authors: Andrade Sancler
Published: May 2023

Abstract Introduction The impact of COVID-19 on occupational and cognitive functioning deserves further exploration since clinicians have observed long COVID and neurological manifestations of COVID-19 long after the remission of respiratory symptoms. Patients with long COVID represent an underexplored population in need of quality occupational therapy interventions. Objectives (a) present an experience report on occupational therapy for assessment and intervention with this population in a hospital setting; (b) demonstrate how perceived occupational performance and health behavior can be improved by the adoption of cognitive strategies and strategies for changing habits. Method This was a single-case study of a long COVID patient in a hospital setting. A description of the framework for assessment and treatment is provided. The patient received a total of nine sessions focused on the use of cognitive strategies and metacognition. The data were analyzed descriptively. Results After exploring guided interventions, the client could create new habits and routines and have perceived occupational performance. Conclusion This experience report presents a framework for assessing and intervening in long COVID that highlights neurocognition. Prospective studies should evaluate if the effects of the proposed awareness assessment and treatment guidelines are reproducible in other settings and if this approach could be helpful for other COVID-19 survivors.

RESUMO O presente artigo apresenta, analisa e discute por que e como pode se pensar a inserção da tecnologia atrelada às ciências e à computação para crianças de 4 e 5 anos na educação infantil. As reflexões aqui exibidas amparam o trabalho realizado desde 2018 no Projeto Aprendendo e Experimentando Tecnologia e Ciências na Educação de Crianças de 4 e 5 Anos. Procura-se deixar de lado o pensamento que reduz o contato com a tecnologia a tablets, celulares ou mesmo montagem de kits de robótica. Nesse sentido, calcados pelos campos da neurociência e da teoria histórico-cultural para pensar o desenvolvimento infantil e pelo conceito de usuário ativo, i.e., aquele que utiliza e cria tecnologias computacionais de forma crítica, significativa, reflexiva e ética, compreendemos que a tecnologia envolve todas as criações humanas que alteram os ambientes natural, cultural e social no qual nos encontramos. Reconhecemos os perigos para o desenvolvimento pleno das crianças que envolvem ao mesmo tempo o reducionismo operado no contato com a tecnologia e propomos um trabalho que não desvincule ciências, matemática, design, engenharia e computação centrado em elementos do cotidiano das crianças.

Abstract This study describes a set of recommendations to improve the precision of shear and punching shear capacity predictions for one-way slabs under concentrated loads, regardless of the governing failure mechanism, using the ABNT NBR 6118:2014 code provisions. For this purpose, a database of 143 test results was developed, including one-way slabs with different support conditions and loading layouts and that failed by different shear failure mechanisms: one-way shear, punching shear or a mixed mode. The key parameters influencing the load capacity and failure mechanism of these slabs were considered for the proposed recommendations: load position and slab width. Adjustments to the effective shear width definition and shear resisting control perimeter were described. Arching action for loads close to the support was also considered in both one-way shear and punching shear predictions. Considering the whole database and without separation by the failure mechanism, the ratio between tested and predicted resistances with the one-way shear expressions shows an average value of 1.22 and a coefficient of variation of 18.3%. The respective ratio between tested and predicted resistances with the punching shear expressions reached an average ratio of 1.23 with a coefficient of variation of 21.3%. Therefore, the proposed recommendations allow for reaching enhanced levels of precision in assessing the shear and punching shear capacity of one-way slabs under concentrated loads, regardless of the governing failure mechanism of the slabs.
Computational modeling of plain and steel fiber-reinforced concrete beams without transverse reinforcement
Authors: Araújo Daniel de Lima , Siqueira Filho Cleiton Rodrigues , Lobo Fausto Arantes
Published: May 2023

Abstract Finite element analysis with nonlinear material behavior modeling can be used to design concrete structures. This study aimed to develop a computational model to represent the shear behavior of concrete beams without transverse reinforcement described in the literature, with or without steel fibers. Two different approaches of finite element analysis were investigated, namely smeared and discrete crack models. The results of the smeared crack model were compared with the results of double-notched push-through tests, and an empirical equation for the shear retention factor of plain concrete was suggested. The computational model using a discrete crack approach with representation of the aggregate interlocking mechanism was compared with the results of push-of test, and an accurate correlation was observed up to the maximum shear stress. It was concluded that the discrete crack approach provided the most accurate representation of the shear behavior of a non-reinforced beam with a shear span-to-depth ratio of 2.17. However, for a non-reinforced beam with a shear span-to-depth ratio of 2.66, the smeared crack approach accurately represents the shear strength and stiffness of the beam. The shear retention factor had little influence on the overall behavior of a steel fiber-reinforced concrete beam. Finally, it was concluded that a variable shear retention factor should be used in the smeared crack approach with fixed crack, as a constant shear retention factor tends to overestimate the shear strength of beams.

Published: May 2023

Abstract The reliability of reinforced concrete (RC) columns in a fire situation is investigated in this paper by combining the General, Equilibrium, and Isotherm at 500 ° C Methods. The well-known Monte Carlo (MC) and the First Order Reliability Method (FORM) are used in a parametric study for the column’s safety. The columns, in a biaxial bending-compression situations, are analyzed by an algorithm that takes into consideration physical and geometric nonlinearities. The dead and live load actions, steel and concrete material strengths, section geometry, model error, and temperature are among the random variables taken into consideration. The findings indicate that increasing the cover can dramatically reduce the probability of failure.

IMPROVEMENT OF COOLING PERFORMANCE AND MITIGATION OF FIRE PROPAGATION IN LITHIUM-ION BATTERIES USING A NOVEL GAS-COOLED THERMAL MANAGEMENT SYSTEM
Authors: Boonkit Pitsanusan , Petchsart Nontawee , Apirakkitthworn Supawut , Trinuruk Piyatida
Published: May 2023

Development of battery thermal management systems has become significant because an inappropriate operating temperature is the primary cause of battery deterioration, fires, and explosions. The current work proposes a revolutionary battery thermal management system that uses an inert gas instead of air as a coolant to increase cooling performance and avoid battery thermal runaway and fire propagation.
The thermal behavior of 18650 cylindrical lithium-ion battery modules was assessed using a test station. The cooling performance of this battery thermal management system was investigated using Ansys Fluent, while the fire dynamics simulator assessed fire propagation when the battery was surrounded by various inert gas coolants. Inert gases can be more effective coolants than air. They
were successful in lowering the maximum temperature and enhancing the convective heat transfer coefficient. Increased turbulent flow contributed in enhancement of heat transfer, as assessed by the Nusselt number. Although all gas coolants in this investigation effectively kept the cell temperature below 60°C, which is the starting temperature of thermal runaway, a high Reynolds number was necessary. Otherwise, helium is the best coolant for transferring heat from a battery, even at extremely low Reynolds numbers. When the battery was surrounded by inert gas, fire propagation in the battery can be minimized. Use of an air-cooling system can initiate fires and explosions when battery thermal runaway occurs.

Authors: Zhu Jiefu , Xiang Xiaohong , Hu Xiaoru , Li Chenglong , Song Zhixia , Dong Zheng
Published: May 2023

Significance Statement

Cold storage-associated transplantation (CST) injury occurs in renal transplant from deceased donors, the main organ source. The pathogenesis of CST injury remains poorly understood, and effective therapies are not available. This study has demonstrated an important role of microRNAs in CST injury and revealed the changes in microRNA expression profiles. Specifically, microRNA-147 (miR-147) is consistently elevated during CST injury in mice and in dysfunctional renal grafts in humans. Mechanistically, NDUFA4 (a key component of mitochondrial respiration complex) is identified as a direct target of miR-147. By repressing NDUFA4, miR-147 induces mitochondrial damage and renal tubular cell death. Blockade of miR-147 and overexpression of NDUFA4 reduce CST injury and improve graft function, unveiling miR-147 and NDUFA4 as new therapeutic targets in kidney transplantation.

Background

Kidney injury due to cold storage–associated transplantation (CST) is a major factor determining the outcome of renal transplant, for which the role and regulation of microRNAs remain largely unclear.

Methods

The kidneys of proximal tubule Dicer (an enzyme for microRNA biogenesis) knockout mice and their wild-type littermates were subjected to CST to determine the function of microRNAs. Small RNA sequencing then profiled microRNA expression in mouse kidneys after CST. Anti–microRNA-147 (miR-147) and miR-147 mimic were used to examine the role of miR-147 in CST injury in mouse and renal tubular cell models.

Results

Knockout of Dicer from proximal tubules attenuated CST kidney injury in mice. RNA sequencing identified multiple microRNAs with differential expression in CST kidneys, among which miR-147 was induced consistently in mouse kidney transplants and in dysfunctional human kidney grafts. Anti–miR-147 protected against CST injury in mice and ameliorated mitochondrial dysfunction after ATP depletion injury in renal tubular cells in intro. Mechanistically, miR-147 was shown to target NDUFA4, a key component of the mitochondrial respiration complex. Silencing NDUFA4 aggravated renal tubular cell death, whereas overexpression of NDUFA4 prevented miR-147–induced cell death and mitochondrial dysfunction. Moreover, overexpression of NDUFA4 alleviated CST injury in mice.

Conclusions

microRNAs, as a class of molecules, are pathogenic in CST injury and graft dysfunction. Specifically, miR-147 induced during CST represses NDUFA4, leading to mitochondrial damage and renal tubular cell death. These results unveil miR-147 and NDUFA4 as new therapeutic targets in kidney transplantation.

Published: May 2023

This research aims to explain the hidden narrative in the slametan of the ulur-ulur ritual at Telaga Buret, Sawo Village, Campurdarat District, Tulungagung Regency. In 2020, during the Covid-19 pandemic, the long sequences of ulur-ulur rituals were summarized by only conducting slametan. This indicates that the main foundation of the ulur-ulur ritual is slametan. To find the core ideology of slametan, this study employed the ethnographic approach. Data were obtained through participatory research and in-depth interview. The collected data were then transcribed and analyzed using related theories. This research shows that in slametan, syncretic narratives are beautifully woven into the ritual. An assortment of narratives from Islam and other religions or beliefs is represented in the offerings served during the ritual. Each offering is addressed specifically to a particular supernatural entity through ujub. This harmonious assortment shows that the Javanese people have a high degree of adaptability when it comes to adjusting their religious practices to inevitable social changes.
Local Self‐Governance and the State in South Sudan: Studying Gendered Tenure Relations in Times of Uncertainty
Authors: Ubink Janine , Almeida Bernardo
Published: May 2023

With governance increasingly regarded as co-governance, states’ capacity to steer, correct, and discipline a wide range of self-governing actors becomes crucial for states’ effectiveness, efficiency, and democracy. This article investigates that capacity and the relationship between formal institutions and customary self-governance in areas of limited statehood. In South Sudan, the field of land governance can be regarded as an area of limited statehood. As land relations are closely connected to clan structures and intra-familial relationships, customary norms and institutions enjoy great legitimacy and are an important locus of local land governance and dispute resolution. The South Sudanese government has promulgated legal provisions for equal rights to property and inheritance that clash head-on with customary notions of gender roles in the family and the preservation of family land. By focusing on the case of women’s land rights in South Sudan, combining literature study with data from exploratory fieldwork in two South Sudanese towns, this article aims to reflect on the cohabitation of customary and formal norms and values and the role formal legal and administrative systems, in areas of limited statehood, can and do play in boundary setting for customary self-governance.

Published: May 2023

Endoscopic trachea stenting is a pressing issue in modern endoscopy. This method is applied in various diseases including benign stenoses associated with complications after long-term mechanical ventilation, malignant stenoses (oncological diseases of the trachea itself, compression from outside by esophageal or mediastinal tumors), post-injury stenoses and developmental defects.

Currently, a certain contingent of patients exists for whom trachea prosthesis and its bifurcation remain the only possible option for stepwise or final treatment. If the lower third of the trachea, bifurcation zone or the main bronchi are affected, the optimal technique is stenting with Y-shaped stents which provide maximal patency of the airways.

The effect of prolonged emotional and pain stress on the expression of the bdnf gene in the brain of rats with contrast excitability of the nervous system
Authors: Shalaginova Irina G. , Zachepilo Tatiana G. , Dyuzhikova Natalia A.
Published: May 2023

BACKGROUND: The neurotrophic factor BDNF performs important functions in synaptic plasticity and functional activity of neurons, involve in the stress response and the pathogenesis of post-stress disorders. The specificity of post-stress changes in the bdnf mRNA level due to genetically determined features of excitability of the nervous system has not been studied.
AIM: To study the level of bdnf mRNA in the prefrontal cortex, hippocampus and amygdala of rats of two strains with contrasting excitability of the nervous system in normal condition and at different times after prolonged emotional and painful stress exposure (after 24 hours, 7, 24, 60 days).
MATERIALS AND METHODS: The study was carried out on adult male rats of two strains with a different level of excitability of the nervous system (HT high threshold and LT low threshold of excitability). As a model of chronic stress, a long-term emotional and painful exposure according to Hecht was used. The bdnf mRNA level was determined using quantitative real-time PCR. Changes in the level of bdnf mRNA in the prefrontal cortex, hippocampus and amygdala of control and experimental groups of rats of two strains were studied at different time points (24 hours, 7, 24 days, 2 months) after prolonged emotional and painful stress exposure.
RESULTS: It was found that in highly excitable LT rats, a decrease in the expression of the bdnf gene in the prefrontal cortex occurs 24 hours and persists up to 7 days after exposure, in the hippocampus 2 months after exposure. In rats of the low-excitable HT strain, the decrease in bdnf mRNA was not detected.
CONCLUSIONS: In highly excitable LT rats, prolonged emotional and painful stress causes a decrease in the expression of the bdnf gene in the prefrontal cortex and hippocampus. In low-excitable rats of the HT strain, no significant decrease in the mRNA level of this neurotrophin was found in any of the studied brain regions. The possible association of this specificity of changes in the level of bdnf mRNA with a greater severity of post-stress anxiety-like behavior disorders in highly excitable rats compared with low-excitable ones is discussed.
