Published: August 2022

A reliable protective layer is one of the main challenges in preventing oxidation of thin film sensors to achieve accurate, effective, and stable readings at high temperatures. In this work, an Al2O3-modified polymer-derived ceramic SiCN composite coating fabricated by a direct-writing technique is utilized as a protective layer for thin film sensors. The microstructure evolution of the Al2O3/SiCN films is examined herein. The protective layer exhibits excellent oxidation resistance and thermal stability at high temperatures up to 1000 °C, which contributes to improving the stability and lifetime of thin film sensors in extreme environments. The TiB2/SiCN thin film resistive grid with the Al2O3/SiCN composite film as a protective layer is fabricated and tested. The results indicate that the coating can protect the TiB2/SiCN thin film resistive grid at high temperatures up to 1000 °C, which is about 200 °C higher than that of the TiB2/SiCN thin film resistive grid without a protective layer. The resistance change rates of the TiB2/SiCN thin film resistive grid with a protective layer are 0.5%/h at 900 °C and 10.7%/h at 1000 °C.

Peat humic acids are well known for their wide range of biological effects which can be attributed to the complex chemical structure of naturally occurring humic substances. One of the promising tools is an ontology-based quantitative analysis of the relationship between physical and chemical parameters describing a chemical structure of peat humic acids and their biological activity. This article demonstrates the feasibility of such an approach to estimate the antioxidant and cell protective properties of the peat humic acids. The structural parameters of the peat humic acids were studied by electronic, fluorescence, infrared, 13C-NMR spectroscopy, titrimetric analysis, elemental C,H,N, and O- analysis, and gel chromatography. Antioxidant and antiradical activities were assessed by physicochemical methods of analysis: electronic paramagnetic resonance, cathodic voltammetry, ABTS•+ scavenging, assay of DPPH radical-scavenging activity, assay of superoxide radical-scavenging activity, iron chelating activity, and scavenging of hydroxyl radicals. Cytoprotective activity was evaluated by the neutral red-based cytotoxicity test in 3T3-L1 cell culture in a wide range of concentrations. Assessment of intracellular ROS production was carried out using a 2,7-dichlorodihydrofluoresceindiacetate (DCFDA) fluorescent probe. Intracellular ROS production was induced using two common prooxidants (tert-butyl hydroperoxide, Fe2+ ions). We suggested an ontology-based model for the antioxidant and cytoprotective activity of humic acids based on experimental data and numerical models. This model establishes the way to further research on the biological effects of humic acids and provides a useful tool for numerical simulation of these effects. Remarkable antioxidant and cell protective activity of humic acids makes them a promising natural source of new pharmaceutical substances that feature a wide range of biological effects.

Published: August 2022

The etherification reaction of ortho-phosphoric acid (OPA) with polyoxypropylene glycol in the presence of tertiary amines was studied. The reaction conditions promoting the catalytic activity of triethanolamine (TEOA) and triethylamine (TEA) in the low-temperature etherification of OPA were established. The catalytic activity of TEOA and TEA in the etherification reaction of phosphoric acid is explained by the hydrophobic-hydrophilic interactions of TEA with PPG, leading, as a result of collective interactions, to a specific orientation of polyoxypropylene chains around the tertiary amine. When using triethylamine, complete etherification of OPA occurs, accompanied by the formation of branched OPA ethers terminated by hydroxyl groups and even the formation of polyphosphate structures. When triethanolamine is used as a catalyst, incomplete etherification of OPA with polyoxypropylene glycol occurs and as a result, part of the phosphate anions remain unreacted in the composition of the resulting aminoethers of ortho-phosphoric acid (AEPA). In this case, the hydroxyl groups of triethanolamine are completely involved in the OPA etherification reaction, but the catalytic activity of the tertiary amine weakens due to a decrease in its availability in the branched structure of AEPA. The kinetics of the etherification reaction of OPA by polyoxypropylene glycol catalyzed by TEOA and TEA were studied. It was shown that triethanolamine occupies a central position in the AEPA structure. The physico-mechanical and thermomechanical properties of polyurethane ionomer films obtained on the basis of AEPA synthesized in a wide temperature range were studied.

This study investigated polymerization kinetics, linear shrinkage, and shrinkage stress development for six contemporary composite materials of different viscosities cured using radiant exitances of 1100–2850 mW/cm2. Real-time measurements of degree of conversion, linear shrinkage, and shrinkage stress were performed over 5 min using Fourier-transform infrared spectrometry, a custom-made linometer, and a custom-made stress analyzer, respectively. For most tested variables, the factor “material” had a higher effect size than the factor “curing protocol”. Maximum polymerization rate and maximum shrinkage stress rate were the most affected by changes in curing conditions. In contrast, no significant effects of curing conditions were identified within each material for shrinkage stress values measured at the end of the 5 min observation period. Linear shrinkage and shrinkage stress values measured after 5 min were closely correlated (R = 0.905–0.982). The analysis of polymerization kinetics suggested that the two composites specifically designed for rapid light-curing responded to higher radiant exitances differently than other composites. Polymerization kinetics and shrinkage stress behavior of contemporary restorative composite materials of different viscosities were overall more affected by material type than differences in curing conditions. Subtle differences in polymerization kinetics behavior shown by the two composites specifically designed for rapid high-intensity light-curing did not translate into significant differences in the development of polymerization shrinkage stress.

Published: August 2022

Soft robotic modules have potential use for therapeutic and educational purposes. To do so, they need to be safe, soft, smart, and customizable to serve individuals’ different preferences and personalities. A safe modular robotic product made of soft materials, particularly silicon, programmed by artificial intelligence algorithms and developed via additive manufacturing would be promising. This study focuses on the safe tactile interaction between humans and robots by means of soft material characteristics for translating physical communication to auditory. The embedded vibratory sensors used to stimulate touch senses transmitted through soft materials are presented. The soft module was developed and verified successfully to react to three different patterns of human–robot contact, particularly users’ touches, and then communicate the type of contact with sound. The study develops and verifies a model that can classify different tactile gestures via machine learning algorithms for safe human–robot physical interaction. The system accurately recognizes the gestures and shapes of three-dimensional (3D) printed soft modules. The gestures used for the experiment are the three most common, including slapping, squeezing, and tickling. The model builds on the concept of how safe human–robot physical interactions could help with cognitive and behavioral communication. In this context, the ability to measure, classify, and reflect the behavior of soft materials in robotic modules represents a prerequisite for endowing robotic materials in additive manufacturing for safe interaction with humans.

Wastewater disinfection is one of the most critical issues in protecting human health against exposure to waterborne pathogenies. Chlorine is among the most commonly used disinfectants in many wastewaters’ treatment plants. Nevertheless, disquiets regarding chlorine’s disinfection by-products (DBPs) have grown recently. One of the most effective ways to reduce DBPs generation is to reduce chlorine dosage by increasing disinfectant efficiency. Using magnetic field (MF) in wastewater treatment is one of the promising research topics with significant progression. This study aimed to evaluate the efficiency of using a magnetic field and/or sodium hypochlorite (NaClO) disinfection on secondary slaughterhouse wastewater effluent quality and by-products. Three groups of secondary slaughterhouse wastewater effluents were used: G1 was treated with NaClO only at 0, 2, 4, and 6 mg/L; G2 was treated with exposure to MF at 14,500 gausses, and G3 was pretreated with MF, then NaClO at the exact chlorine dosages and MF strength. The results showed an augmented effect when using a magnetic field as a pre-treatment step before NaClO treatment in the remediation of slaughterhouse wastewater over the use of any of them solely. The removal rate of COD and BOD increased by up to 26 and 20%, respectively, when pre-treatment with MF was employed as a mean percentage at all chlorine dosages, while TSS, TDS, and EC increased by 23.5 and 5.5%, respectively. Over and above, the removal rate for each TN and TP increased by 12 and 6.5% as a mean percentage at all chlorine dosages when using a combination of the two. In addition, pre-treatment by MF reduced the required concentration of NaClO from 6 to 4 mg/L, resulting in an 11% increase in the reduction rate of total coliform count, 8% increase in the reduction rate of fecal coliforms, and 10% increase in the reduction rate of E. coli and 5% in Salmonella via increasing the disinfection efficiency of NaClO. Finally, it decreased the concentration of Chloroform produced by more than 77.2% by using the higher concentration of NaClO (6 mg/L). The issue that approved the promising approach of using MF as a pre-treatment step in the treatment of slaughterhouse wastewater provides the advantage of using smaller dosages of disinfection, lowering the cost of the procedure process, and reducing the harmful concentration of DBPs.

Published: August 2022

With the rapid development of new power systems, various new power devices have also been developed. It is very important to establish analytical models of new power devices to ensure or even improve the reliability and stability of the power system. A linear phase-shifting transformer (LPST) is a new type of power device that mainly relies on air gaps to transfer energy, so establishing an accurate air-gap magnetic field model is very important for improving the efficiency of this system. In this paper, an analytical model of an unequal-pitch linear phase-shifting transformer (UP-LPST) was established by combining the distributed magnetic circuit method (DMCM) and Schwartz–Christopher transformation (SCT). Taking the magnetic field strength as a variable, an accurate magnetic field analysis model for a UP-LPST considering saturation, cogging, and edge was established. Taking a 1 kw UP-LPST as a prototype, the accuracy of the model was verified by the finite element method and experiments. This modeling method could also be used to establish magnetic field models of other similar structures in new energy power systems, especially those with cogging structures.

Key Points

In heme protein–induced AKI, mitochondrial functional integrity, as reflected by ATP and NAD+ content and NAD+/NADH ratio, is impaired.

Mitochondrial quality control is compromised as reflected by impaired biogenesis, exaggerated fission, and marked ultrastructural damage.

Modern concepts regarding mitochondria and AKI apply to heme protein–induced AKI, with the possibility of novel therapeutic strategies.

Background

Mitochondrial injury occurs in and underlies acute kidney injury (AKI) caused by ischemia-reperfusion and other forms of renal injury. However, to date, a comprehensive analysis of this issue has not been undertaken in heme protein–induced AKI (HP-AKI). We examined key aspects of mitochondrial function, expression of proteins relevant to mitochondrial quality control, and mitochondrial ultrastructure in HP-AKI, along with responses to heme in renal proximal tubule epithelial cells.

Methods

The long-established murine glycerol model of HP-AKI was examined at 8 and 24 hours after HP-AKI. Indices of mitochondrial function (ATP and NAD+), expression of proteins relevant to mitochondrial dynamics, mitochondrial ultrastructure, and relevant gene/protein expression in heme-exposed renal proximal tubule epithelial cells in vitro were examined.

Results

ATP and NAD+ content and the NAD+/NADH ratio were all reduced in HP-AKI. Expression of relevant proteins indicate that mitochondrial biogenesis (PGC-1α, NRF1, and TFAM) and fusion (MFN2) were impaired, as was expression of key proteins involved in the integrity of outer and inner mitochondrial membranes (VDAC, Tom20, and Tim23). Conversely, marked upregulation of proteins involved in mitochondrial fission (DRP1) occurred. Ultrastructural studies, including novel 3D imaging, indicate profound changes in mitochondrial structure, including mitochondrial fragmentation, mitochondrial swelling, and misshapen mitochondrial cristae; mitophagy was also observed. Exposure of renal proximal tubule epithelial cells to heme in vitro recapitulated suppression of PGC-1α (mitochondrial biogenesis) and upregulation of p-DRP1 (mitochondrial fission).

Conclusions

Modern concepts pertaining to AKI apply to HP-AKI. This study validates the investigation of novel, clinically relevant therapies such as NAD+-boosting agents and mitoprotective agents in HP-AKI.

Published: August 2022

Tourism is one of the sectors most affected by the Covid-19 pandemic since tourism was linked to the outbreak of the virus through the travel of tourists from the affected countries. Furthermore, tourism and related sectors were among the sectors that nearly closed completely through the full and partial lockdown, which represented the most prominent government procedures to limit the spread of the virus. Therefore, this study is the first of its kind that attempted to explore the impact of the pandemic on the tourism sector and assess the government’s role in supporting the sector and preventing its collapse. Both qualitative and quantitative approaches were used to identify the main issues that must be covered to explore the impact of the pandemic on the tourism sector, and then develop a questionnaire that was answered by 59 tourism organizations. Based on the data analyses and the hypotheses testing the study concluded that despite the great procedures and efforts undertaken by the Jordanian government to support the tourism sector, they did not meet the magnitude of the harm and did not fulfill the sector hopes in terms of injecting liquidity, supporting small and medium enterprises, and empowering their workers to continue to work and meet the new tourism requirements for the post-Covid-19 era. The study suggested an agenda to improve the government's support of the tourism sector and bring it to safety.
Dieta neoliberal: ¿cuestión cultural o económica?
Authors:   Simon Fraser University, Otero Gerardo ,   Asociación de Estudios Latinoamericanos (LASA)
Published: August 2022

En este capítulo se considera si el paquete alimentario que predomina en México es algo determinado por la cultura o más bien por factores económicos. El argumento principal es que, si bien el país disfrutó de las posibilidades de tener su propia dieta tradicional hasta los 1980, la apertura comercial y la desigualdad económica han causado una modificación sustancial de la dieta a favor de alimentos densos en contenido energético y con menor valor nutritivo. La creciente exportación de frutas y verduras las hizo cada vez más caras dentro del país, por lo cual la cocina tradicional se hizo más inviable. Al respecto, se presenta una conceptualización del régimen alimentario neoliberal y su dieta. En ese marco, se propone que esta dieta ha sido la raíz principal de las comorbilidades que han estado asociadas a la pandemia de covid-19: sobrepeso, obesidad, diabetes, hipertensión, etcétera. Es decir, lo que se denomina «dieta neoliberal» ha convertido a los mexicanos en una población más vulnerable. Recuperar la salud en México pasa por recuperar también la soberanía alimentaria mediante la regeneración del campo y sus campesinos. Dadas las urgencias del cambio climático, dicha regeneración pasa también por el empleo de métodos de producción agroecológicos.
Mutaciones en la economía política mundial: pandemia, capitalización y estatalismo

La crisis derivada de la pandemia de covid-19 no se ha generalizado del todo en el campo económico. Evidentemente, existen grandes ganadores, destacadamente las grandes corporaciones tecnológicas y farmacéuticas, así como una amplia y extensa gama de perdedores, como los sectores de energía, el transporte y los pequeños negocios, pero sobre todo los trabajadores. Sin embargo, es posible advertir que hay ganadores dentro de las actividades perdedoras, como es el caso de las grandes corporaciones petroleras internacionales, que pese a experimentar un fuerte revés, eventualmente pueden salir airosas y tomar beneficio de la situación de quiebra de empresas que son sus competidores, pero que tienen una densidad de capital más pequeña, menores recursos tecnológicos y menor participación en el mercado. Los grandes beneficiarios de la crisis de la pandemia podrán sacar partido de la catástrofe humanitaria y hacer uso de su amplio margen de liquidez y de sus abultados márgenes de ganancia para realizar inversiones estratégicas que les permitan absorber a sus competidores y lograr consolidar una posición más concentrada de capital y un dominio geoestratégico que los prepara convenientemente para el futuro inmediato, cuando la «nueva normalidad» reencauce a los capitales sobrevivientes de la devastación y se recompongan los ciclos de inversión, los planes de negocio y las grandes obras de infraestructura. Con ello, se pergeña una economía mundial más concentrada en grandes poderes económico-políticos representados por gigantes corporaciones, mayores contenidos tecnológicos e interconexiones más globalizadas.
Prácticas materiales de cuidado de la agrobiodiversidad como marco simbólico para la gobernanza ambiental en el sur de Tolima, Colombia
Authors:   Pennsylvania State University, Baumann Megan Dwyer
Published: August 2022

The literature on agrobiodiversity examines in a broad way the interactions between plants and humans in farming biomes, and often includes the study of the governance of seeds as a genetic resource. This article turns its attention to agrobiodiversity as a mesh of manageable genetic resources in order to examine how the characteristics of agrobiodiversity symbolize a vision of future environmental governance. First reviewing the existing perspectives in political ecology on environmental governance and feminist ethics of care, the results of this study reveal that the established practices of «total care» of agrobiodiversity, in particular the exchange of seeds, vegetable gardens and kitchens, have become a symbolic framework for environmental governance in which Access to land, food and community cohesion are guaranteed and protected.

Statistical investigation of dislocation induced leakage current paths in AlGaN/GaN HEMT structures on Si and the impact of growth conditions
Authors: Besendörfer Sven , Meissner Elke , Friedrich Jochen
Published: August 2022

Threading dislocations in the AlGaN-barrier of four pairwise differently grown AlGaN/GaN high electron mobility transistor structures on Si were investigated with respect to their structural and electrical properties in direct comparison simultaneously ensuring statistical significance of the results. Portions of pure screw and mixed type dislocations were observed to serve as leakage current paths and to be clearly dependent on growth conditions like the AlN nucleation layer growth temperature. The role of impurity segregation at dislocation cores due to growth-dependent locally characteristic strain fields as for example induced by specific dislocation reactions at the AlGaN/GaN interface is discussed as the origin.

Cognitieve animatietherapie
Authors: Camp Paul
Published: August 2022

Cognitieve animatietherapie is het eerste boek waarin deze vernieuwende vorm van psychotherapie wordt beschreven. Een belangrijk uitgangspunt van de therapie is dat problemen waarmee cliënten te kampen hebben, zich in veel opzichten gedragen alsof ze een eigen leven leiden. De behandeling is er in eerste instantie op gericht dat cliënten hun identificatie met het probleem verminderen. Door het probleem met concrete middelen – onder meer interactieve computeranimaties – in kaart te brengen, leren cliënten strategieën herkennen en denkfouten verminderen. Daarnaast besteden therapeuten veel aandacht aan het leren voorzien in de vaak verwaarloosde behoeften die aan het probleem ten grondslag liggen. Paul Camp voegt met de introductie van de evolutionaire functietheorie een nieuwe dimensie toe aan de psychotherapie. Uitgangspunt is daarbij dat achter alle gedachten, emoties en gedrag een ‘goede bedoeling’ schuilgaat die wordt ingegeven door evolutionaire processen. De theorie leidt tot nieuwe interventies, biedt een betere verklaring voor de werkzaamheid van bestaande interventies en integreert vrijwel alle vormen van reguliere psychotherapie in een logisch model. Cognitieve animatietherapie is toepasbaar bij alle soorten problematiek en voor cliënten van alle leeftijden. Paul Camp heeft hiermee, in heldere bewoordingen en geïllustreerd door verschillende praktijkvoorbeelden, een inspirerend handboek geschreven, dat iedere hulpverlener, (ortho)pedagoog, psycholoog, student, beginnend of gevestigd therapeut gelezen moet hebben.

Published: August 2022

Tuak Dayak is an alcoholic drink that is often consumed by the people of West Kalimantan. Infertility is related to ROS levels as a result of alcohol oxidative stress. This study aims to determine the effect of tuak dayak on the 8-OHdG levels of semen and testicular weight. This research is an experimental study using experimental methods with a post-test-only randomized control group design. The research subjects were 25 rats, randomly divided into 5 groups. Group K0 was only given 3.6 mL/kgBW/day of distilled water, groups K1 and K2 were given Tuak Aren at doses of 1.8 and 3.6 mL/kgBW/day, and groups K3 and K4 were given Tuak Dayak at doses of 1.8 and 3.6 mL/kgBW/day. Treatment for 4 weeks. On day 29, semen and testes were taken. The testes are weighed with an electric weigher. Analysis of semen in the testes was performed to check the levels of 8-OHdG. The results of the Mann-Whitney test on K4 and K3 had no effect on the 8-OHdG content of cement. The average result in K4 was the number of Leydig cells 3.68±0.18, the thickness of the tubular tissue was 2.13±0.14µg, and the testicular weight was 0.91±0.09 g, the lowest. The average 8-OHdG content of cement was 0.22±0.01 ng/mL, the lowest was K2, and the highest was at K0 1.14±0.05 g/mL. In conclusion, Tuak Dayak had the effect of lowering testicular weight but did not show any effect on the activity of 8-hydroxy-2'deoxyguanosine (8-OHdG) in the semen of rats.

Published: August 2022

Sugarcane, Saccharum officinarum L., has economic importance in Brazil and the world. In addition to its global value as the main source of sugar, energy, and ethanol, it is a raw material for several products. However, phytosanitary problems cause significant losses in the agricultural production of the crop, of which most are only due to the ineffective management of insect pests. We evaluated the impact of the application of insecticides used in sugarcane crops on the predation of eggs of Ephestia kuehniella (Zeller) (Lepidoptera: Pyralidae) under field conditions. For this, cards containing 30 eggs of this species were fixed in the middle third of sugarcane plants and exposed to predation by insects present in areas sprayed with insecticides: thiamethoxam; lambda-cyhalothrin + thiamethoxam; fipronil and Metarhizium anisopliae, in addition to a control (area without spraying). The dose used for insecticides was the minimum recommended for control of insect pests in the crop. The cards remained in the areas for 24 hours after the insecticides spraying, being collected for evaluation after this period. The cards from areas sprayed with thiamethoxam; lambda-cyhalothrin + thiamethoxam and fipronil, the average number of eggs remaining was significantly higher.

Objetivou-se validar o Instrumento de Planejamento e Avaliação Didática de Questões Sociocientíficas (IPADQSC), como material instrucional de apoio ao professor para auxiliar no planejamento e avaliação das sequências de ensino, com foco na ampliação do letramento científico dos estudantes. A validação ocorreu em três fases: (i) elaboração do instrumento e de critérios de análise; (ii) análise e apreciação aos pares; (iii) aplicação do material.  A geração e definição de itens para composição do instrumento e o estabelecimento de critérios de avaliação foi baseada no referencial teórico sobre ensino investigativo, questões sociocientíficas, divulgação e letramento científico, e orientações didático pedagógica. A análise foi realizada por 30 avaliadores da área, considerando três categorias: estrato baixo, composto por estudantes de pós-graduação em ensino de ciências; estrato médio, incluindo professores da educação básica; estrato alto, representado por professores universitários. Todos avaliaram o mesmo questionário composto por 29 critérios sobre aspectos teóricos, metodológicos e didáticos referente ao instrumento. A apreciação dos pares revelou que sete dos 29 critérios estavam abaixo do percentual de anuência, cuja indicações foram atendidas para conferir melhor clareza. O instrumento foi aplicado para 107 professores de Ciências e Biologia em formação inicial e continuada durante um curso de formação na forma de ensino remoto devido a pandemia. Observou-se que os professores participantes demonstraram bom entendimento e facilidade para uso do instrumento para elaboração de 21 propostas de sequência de ensino, como atividade avaliativa do curso, sugerindo que o IPADQSC atendeu aos critérios de estrutura e organização, relevância didática, questões teóricas e metodológicas satisfatoriamente. Verificou-se que o instrumento se torna válido e pode ser amplamente divulgado para utilização na prática pedagógica, na sua forma original ou com adaptações, atendendo a diferentes realidades.

Estas son las consideraciones críticas que se hacen en un artículo titulado: Aprendizaje activo y aprendizaje más profundo: reflexiones sobre las demandas de una educación en sintonía con su época. Texto seleccionado para la actividad requerida como requisito en la asignatura de Actualidad en la Enseñanza de las Ciencias, del Doctorado Profesional en Enseñanza de las Ciencias, del Instituto Federal de Educación de Rio de Janeiro. El objetivo es presentar los aportes de la metodología activa en la mirada de Almeida (2020), involucrando tecnologías que centralizan al alumno en la discusión, interactuando y resolviendo problemas en su contexto con proyectos. Como metodología, traemos un breve análisis crítico desde el punto de vista pedagógico de la propuesta de tesis. Los resultados señalan algunos obstáculos en la concepción más tradicional de la educación que contribuyen a la no emancipación del aprendizaje de los estudiantes. Consideramos que el educador necesita ver las tecnologías como aliadas y apropiarse de metodologías que activen el deseo de investigar y resolver problemas.

At the end of this review the following questions will be addressed by summarizing data of in-vitro studies: which nut extract has the strongest inhibitory effect? Which functional component (e.g. polyphenols) has the strongest inhibitory effect against α-glucosidase? Are there any differences between inhibition of α-glucosidase from different sources (e.g. yeast and mammalian)? Condition being studied: Any papers looking at inhibition of α-glucosidase activity (a carbohydrate digestive enzyme; includes sucrase, maltase and isomaltase activities) by extracts of edible parts of nut will be included in this review.
