Published: October 2021

MEMS resonators have become core devices in a large number of fields; however, due to their complex structures, the finite element analysis (FEA) method is still the main method for their theoretical analysis. The traditional finite element analysis method faces the disadvantages of large calculation amount and long simulation time, which limits the development of high-performance MEMS resonators. This paper demonstrates a high-speed and high-accuracy simulation tool based on the artificial neural network, where a multilayer perceptron (MLP) neural network model is constructed. The typical structural parameters of MEMS resonator are used as the input layer, and its performance indicators produced by the finite element analysis method are the output layer. After iteratively trained with 4000 samples, the cumulative error of the neural network decreases to 0.0017 and a prediction network model is obtained. Compared with the finite element analysis results, the structural accuracy error predicted by the neural network model can be controlled within 6%, but its runtime is shortened by 15,000 times. This high-speed and high-accuracy mathematical modeling method can effectively improve the analyzing efficiency and provide a promising tool for the design and optimization of different complex MEMS resonators, which exhibit remarkable accuracy and speed.

In 2011, an outbreak of hemorrhagic colitis and hemolytic uremic syndrome (HUS) was reported in Europe that was related to a hybrid STEAEC of Escherichia coli (E. coli) O104:H4 strain. The current study aimed to analyze strains of E. coli O104 and O9 isolated before 2011. The study included 47 strains isolated from children with and without diarrhea between 1986 and 2009 from different geographic regions, as well as seven reference strains. Serotyping was carried out on 188 anti-O and 53 anti-H sera. PCR was used to identify DEC genes and phylogenetic groups. Resistance profiles to antimicrobials were determined by diffusion in agar, while PFGE was used to analyze genomic similarity. Five serotypes of E. coli O104 and nine of O9 were identified, as well as an antigenic cross-reaction with one anti-E. coli O9 serum. E. coli O104 and O9 presented diarrheagenic E. coli (DEC) genes in different combinations and were located in commensal phylogenetic groups with different antimicrobial resistance. PFGE showed that O104:H4 and O9:(H4, NM) strains from SSI, Bangladesh and México belong to a diverse group located in the same subgroup. E. coli O104 and O9 were classified as commensal strains containing DEC genes. The groups were genetically diverse with pathogenic potential making continued epidemiologic surveillance important.

Published: October 2021

Fluorite mineralization associated with different types of magmatism is common in the Western Transbaikalia. This study deals with Arshan, Yuzhnoe, and Ulan-Ude fluorite occurrences, which are the most significant examples of carbonatite-related fluorite mineralization in the region. The present paper focused on new fluorite geochemistry and fluid inclusion data, is aimed at revealing conditions of the fluorite mineralization formation, highlighting its genetic relationship with magmatism, compared to other deposits of this type. All the three locations belong to the Late Mesozoic Central Asian carbonatite province. Fluorites here are characterized by high rare earth elements (REE), Sr, and elevated La/Yb values. Fluid inclusions data imply that the formation of fluorite mineralization is a long process extending from late magmatic to the hydrothermal stage. Early fluorite crystallized from sulfate-carbonate orthomagmatic fluids at temperatures up to 500 °C. True hydrothermal fluorite was formed from the same fluids that were probably mixed with meteoric waters, which caused the temperature to drop to below 420 °C and led to an increase in the chloride component. The REE compositions of fluorite from the studied locations are similar to compositions of REE-rich fluorites from carbonatite-related deposits around the world.

Published: October 2021

The study of lateritic bauxite by electron microscopy revealed abundant products of interaction between organic matter and minerals. Abundant biomineral films of different genesis and composition were found, including Al, Fe, Al-Fe, Al-Si, Al-Fe-Si, sorbed rare and rare-earth elements (REE). The evolution of these films from amorphous to crystallized and the conversion into druse crystals of gibbsite, hematite, kaolinite etc. was traced. New data were obtained on mineralization of deposits of wood, roots, biofilms and bacteria in tropical conditions. Mono- and multilayer films were identified. Different composition biofilms occurred before and after seasonal monsoon rains. The mineral composition of the films is influenced by micro-local conditions and the introduction of chemical elements, including rare and rare-earth elements, with capillary water during the dry seasons. The products of biomineralization are microscopic in size, but are of universal and global importance to all weathered rocks and associated bauxite deposits.

Published: October 2021

The topic of residual subsidence is important in Europe as it defines possible surface deformation for closed mine areas. It has to be determined because of potential financial claims and damages of sensitive objects such as satellite dishes, precision mechanics objects, agriculture, forestry and hydrogeology, etc. Analyses of measured subsidence after the end of mining exploitation indicate that this process can last from several months to several dozen or even several hundred years, and the final surface subsidence is not known. It is dependent on the individual’s features of excavated medium, depth of exploitation, a system of exploitation, behaviour of surrounding rock masses, etc. In the article, the authors analysed the assessment of the subsidence process after the end of mining operations, based on the innovative method. This concerns the duration of the subsidence process and the size of the expected subsidence. The methodology was applied to the RAG Aktiengesellschaft company project where prognostic calculations were made for seven closed coal mines using unique results of precise height measurements carried out for more than 90 years by the German State Office for National Measurements (Landesvermessungsamt NRW) under the so-called levelling measurements net. These measurements are carried out every 2 years and serve to keep the altitude network in the whole state of Rhineland Westphalia up-to-date. The result of the prognosis for one case study, German mine Auguste-Victoria, is presented in the article.

Published: October 2021

The production of noble metals has started to shift towards using different types of wastes. The leaching solutions collected during the processing of waste have low concentrations of noble metals; therefore, it forces the use of sorption methods in recovery technology. This work focused on recovering noble metals with a technological solution, obtained during the processing of waste from refining processes. The research consisted of a set of experiments using a batch method that enabled determination of the parameters of the process and selection of the leading resins. Sorption isotherms were determined and kinetic studies were conducted, along with the preliminary elution tests with the use of different eluents. Cementation experiments were the final part of the research. During the experiments, it was concluded that the leading resins for the sorption of noble metals were Puromet MTS9200, Puromet MTS9850, and Lewatit K 6362. The volume ratio Vr:Vs = 1:10 and the reaction time 15–30 min could be used as basic conditions to conduct the experiments in the column; the solution of thiourea in hydrochloric acid can be used as an eluting agent from which noble metals could be cemented using powder zinc.

Published: October 2021

A heterogeneous Janus-type palladium interphase catalyst was obtained by selective surface modification of a hollow mesoporous silica material. The catalyst comprises hydrophobic octyl groups on one side of the silica nanosheets and single-site bis-imidazoline dichlorido palladium(II) complexes on the other. The structure of this composite material has been analyzed by means of elemental analysis, atomic absorption spectroscopy, BET surface analysis, TGA, SEM and solid-state CP-MAS 13C and 29Si NMR spectroscopy. The catalyst showed extraordinary activity for the aqueous-phase oxidation of styrene to acetophenone using 30% hydrogen peroxide as the oxidant. An 88% yield of acetophenone could be achieved after 60 min.

Published: October 2021

Photochromic molecules are systems that undergo a photoisomerization to high-energy isomers and are attractive for the storage of solar energy in a closed-energy cycle, for example, in molecular solar thermal energy storage systems. One challenge is to control the discharge time of the high-energy isomer. Here, we show that different substituents in the ortho position of a phenyl ring at C-2 of dihydroazulene (DHA-Ph) significantly increase the half-life of the metastable vinylheptafulvene (VHF-Ph) photoisomer; thus, the energy-releasing VHF-to-DHA back-reaction rises from minutes to days in comparison to the corresponding para- and meta-substituted systems. Systems with two photochromic DHA-Ph units connected by a diacetylene bridge either at the para, meta and ortho positions and corresponding to a linear or to a cross-conjugated pathway between the two photochromes are also presented. Here, the ortho substitution was found to compromise the switching properties. Thus, irradiation of ortho-bridged DHA-DHA resulted in degradation, probably due to the proximity of the different functional groups that can give rise to side-reactions.

Authors: Ma Xiaoli , Li Xinbo , Zhang Wenrui , Meng Fanxing , Wang Xin , Qin Yanan , Zhang Minwei
Published: October 2021

Carbon-based nanomaterials have become the subject of intensive interest because their intriguing physical and chemical properties are different from those of their bulk counterparts, leading to novel applications in smart sensors. Mycotoxins are secondary metabolites with different structures and toxic effects produced by fungi. Mycotoxins have low molecular weights and highly diverse molecular structures, which can induce a spectrum of biological effects in humans and animals even at low concentrations. A tremendous amount of biosensor platforms based on various carbon nanocomposites have been developed for the determination of mycotoxins. Therefore, the contents of this review are based on a balanced combination of our own studies and selected research studies performed by academic groups worldwide. We first address the vital preparation methods of biorecognition unit (antibodies, aptamers, molecularly imprinted polymers)-functionalized carbon-based nanomaterials for sensing mycotoxins. Then, we summarize various types of smart sensors for the detection of mycotoxins. We expect future research on smart sensors to show a significant impact on the detection of mycotoxins in food products.
An Updated View on the Antiviral Therapy of Hepatitis C in Chronic Kidney Disease
Authors: Fabrizi Fabrizio , Cerutti Roberta , Messa Piergiorgio
Published: October 2021

Background: Hepatitis C virus infection remains common in patients with chronic kidney disease, including those on maintenance dialysis. The relationship between hepatitis C virus infection and chronic kidney disease is bi-directional; in fact, HCV is both a cause and consequence of chronic kidney disease. According to a systematic review with meta-analysis of observational studies (n = 23 studies) (n = 574,081 patients on long-term dialysis), anti-HCV positive serologic status was an independent and significant risk factor for death in patients with advanced chronic kidney disease on long-term dialysis. The overall estimate for adjusted mortality (all-cause death risk) with HCV was 1.26 (95% CI, 1.18; 1.34) (p < 0.0001). Interferon-based therapies are biased by low efficacy/safety in chronic kidney disease, but the advent of direct-acting antiviral drugs has made a paradigm shift in the treatment of HCV-infection. These medications give interruption of viral replication because they target specific non-structural viral proteins; four classes of DAAs exist-NS3/4A protease inhibitors, NS5A inhibitors, NS5B nucleoside and non-nucleoside polymerase inhibitors. All-oral, interferon-free, ribavirin-free combinations of DAAs are now available. Aim: The goal of this narrative review is to report the available treatment options for HCV in advanced chronic kidney disease. Methods: We have made an extensive review of the medical literature and various research engines have been adopted. Results: Some combinations of DAAs are currently recommended for HCV in advanced CKD (including patients on maintenance dialysis): elbasvir/grazoprevir; glecaprevir/pibrentasvir; and sofosbuvir-based regimens. Solid evidence, based on registration and “real life” studies supports their efficacy (SVR rates > 90%) and safety even in patients with advanced CKD. No dosage adjustment is necessary and treatment duration is 8–12 weeks. However, recent data highlight that many patients with advanced CKD remain untreated, and numerous barriers to antiviral treatment of HCV still exist. Whether successful antiviral therapy with DAAs will translate into improved survival in the advanced CKD population is another point of future research.

Published: October 2021

The use of biological drugs has improved outcomes in pediatric inflammatory bowel disease (IBD). Prediction of the response to biological drugs would be extremely useful in IBD, and even more so in children, who are still growing physically and psychologically. Specific clinical, biochemical, and genetic parameters are considered predictive of response to biological drugs, although few studies have been carried out in children with IBD. In this review, we present current evidence on biological treatments used in pediatric IBD and the available biomarkers of response. We examine demographics, clinical characteristics, biomarkers (genetic, genomic, and cellular), and microbiota.

Published: October 2021

Metal complexes based on transition metals have rich photochemical and photophysical properties that are derived from a variety of excited state electronic configurations triggered by visible and near-infrared light. These properties can be exploited to produce powerful energy and electron transfer processes that can lead to oxygen-(in)dependent photobiological activity. These principles are the basis of photodynamic therapy (PDT), which is a clinically approved treatment that offers a promising, effective, and noninvasive complementary treatment or even an alternative to treat several types of cancers. PDT is based on a reaction involving a photosensitizer (PS), light, and oxygen, which ultimately generates cytotoxic reactive oxygen species (ROS). However, skin photosensitivity, due to the accumulation of PSs in skin cells, has hampered, among other elements, its clinical development and application. Therefore, these is an increasing interest in the use of (metal-based) PSs that are more specific to tumor cells. This may increase efficacy and corollary decrease side-effects. To this end, metal-containing nanoparticles with photosensitizing properties have recently been developed. In addition, several studies have reported that the use of immunogenic/immunomodulatory metal-based nanoparticles increases the antitumor efficacy of immune-checkpoint inhibitor-based immunotherapy mediated by anti-PD-(L)1 or CTLA-4 antibodies. In this review, we discuss the main metal complexes used as PDT PSs. Lastly, we review the preclinical studies associated with metal-based PDT PSs and immunotherapies. This therapeutic association could stimulate PDT.

Published: October 2021

The present study demonstrated that 2′-hydroxycinnamaldehyde (2′-HCA) induced apoptosis in human promyelocytic leukemia HL-60 cells through the activation of mitochondrial pathways including (1) translocation of Bim and Bax from the cytosol to mitochondria, (2) downregulation of Bcl-2 protein expression, (3) cytochrome c release into the cytosol, (4) loss of mitochondrial membrane potential (ΔΨm), and (5) caspase activation. 2′-HCA also induced the activation of c-Jun N-terminal kinase (JNK) and extracellular signal-regulated kinase1/2 (ERK1/2) in HL-60 cells. The pharmacological and genetic inhibition of JNK effectively prevented 2′-HCA-induced apoptosis and activator protein-1 (AP-1)-DNA binding. In addition, 2′-HCA resulted in the accumulation of reactive oxygen species (ROS) and depletion of intracellular glutathione (GSH) and protein thiols (PSH) in HL-60 cells. NAC treatment abrogated 2′-HCA-induced JNK phosphorylation, AP-1-DNA binding, and Bim mitochondrial translocation, suggesting that oxidative stress may be required for 2′-HCA-induced intrinsic apoptosis. Xenograft mice inoculated with HL-60 leukemia cells demonstrated that the intraperitoneal administration of 2′-HCA inhibited tumor growth by increasing of TUNEL staining, the expression levels of nitrotyrosine and pro-apoptotic proteins, but reducing of PCNA protein expression. Taken together, our findings suggest that 2′-HCA induces apoptosis via the ROS-dependent JNK pathway and could be considered as a potential therapeutic agent for leukemia.

Authors: Galipienso Luis , Elvira-González Laura , Velasco Leonardo , Herrera-Vásquez José Ángel , Rubio Luis
Published: October 2021

High-throughput sequencing from symptomatic tomato and pepper plants collected in Panama rendered the complete genome of the southern tomato virus (isolate STV_Panama) and bell pepper endornavirus (isolate BPEV_Panama), and almost-complete genomes of three other BPEV isolates. Tomato chlorosis virus, tomato mosaic virus, and impatiens necrotic spot virus were also detected. Analysis of the complete genome of STV and BPEV worldwide isolates revealed nucleotide diversities of 0.004246 and 0.070523, respectively. Bayesian phylogenetic analysis showed two main groups for each virus (I and II), and several subgroups for BPEV (IA, IB, IC, IIA and IIB). Isolate STV_Panama clustered with NC_12-03-08 from USA and Tom3-T from France (99.97% nucleotide identity) in Group I and BPEV_Panama was close to the Canadian isolate BPEV_Ontario (99.66% nucleotide identity) in Subgroup IB. No correlation was observed between geographic and genetic distances for both viruses. Panamanian BPEV isolates were divergent, belonging to Groups I and II (nucleotide identities > 87.33%). Evolutionary analysis showed purifying selection in all encoding regions of both viruses, being stronger in the overlapping region of both STV genes. Finally, recombination was detected in BPEV but not in STV. This is the first report of STV and BPEV in Panama.

Published: October 2021

The effectiveness of mulch treatments on soil quality as well as on the yield and growth rates of bamboo are major considerations and require further attention. The present work was aimed at assessing the impacts of three different mulch materials on soil available nutrients, biochemical traits, and growth patterns of Dendrocalamus latiflorus Munro. We found that relative to the control (CK), bamboo leaves (MB) and organic fertilizers (MF) treatments significantly (P < 0.05) increased the number of bamboo shoots (47.5 and 22.7%) and yield (21.4 and 9.1%), respectively. We observed that under MB and MF treatments, the concentrations of soil available nutrients (nitrogen, phosphorus, and potassium) increased and played a key role in the differences in chlorophyll, leaf carbohydrate contents (soluble sugar and starch) and were essential to promote bamboo shoot development. Furthermore, we infer from principal component analysis (PCA), that both MB and MF appear to be a better choice than rice husks (MR) to improve nutrient availability, biochemical traits of the leaves, and increased bamboo shoot productivity. Consequently, we suggest using organic fertilizers and bamboo leaves as mulch materials are effective for soil conservation to attain high-quality bamboo production.
Experimental Determination of Molecular Weight-Dependent Miscibility of PBAT/PLA Blends
Authors: Su Shen , Kopitzky Rodion , Berrenrath Christian
Published: October 2021

Blends of poly(butylene adipate-co-terephthalate) (PBAT) and polylactide (PLA) have attracted the attention of academia and industry as a sustainable material. Unfortunately, this combination results in problems related to poor miscibility on the molecular level. This study mainly aims to determine the influence of molecular weights on the miscibility of PBAT/PLA blends. First, polymers with various molecular weights were obtained by the hydrolysis of PBAT and methanolysis of PLA. Second, the two components were solution-blended with different molecular weights and weight ratios. Third, each blend was heated to the molten state and subsequently stored at room temperature. Finally, the samples were tested using DSC and SEM. The thermal analysis indicated that the difference in glass transition temperature between both components decreased from about 91 °C to 57 °C and 0 °C, as the number-average molecular weights (Mn) decreased from 52/127 to 9.4/9 and 6.3/6.6 kg/mol. Moreover, the morphology changed from phase-separated with dispersed large particles gradually to uniform and homogeneous. This experimental work validated the trends predicted in the previous study, namely that PBAT/PLA blends changed the state from immiscible to partially miscible to fully miscible with decreasing Mn values. Moreover, we discussed the influencing factors such as weight ratio, temperature, and molecular structure on the miscibility. Based on the results, this work contributes to developing partially miscible and compatible blends without additives.

Published: October 2021

Humans are currently experiencing the fourth industrial revolution called Industry 4.0. This revolution came about with the arrival of new technologies that promise to change the way humans work and interact with each other and with machines. It aims to improve the cooperation between humans and machines for mutual enrichment. This would be done by leveraging human knowledge and experience, and by reactively balancing some complex or complicated tasks with intelligent systems. To achieve this objective, methodological approaches based on experimental studies should be followed to ensure a proper evaluation of human-machine system design choices. This paper proposes an experimental study based on a platform that uses an intelligent manufacturing system made up of mobile robots, autonomous shuttles using the principle of intelligent products, and manufacturing robots in the context of Manufacturing 4.0. Two experiments were conducted to evaluate the impact of teamwork human-machine cooperation, performance, and workload of the human operator. The results showed a lower level of participants’ assessment of time demand and physical demand in teamwork conditions. It was also found that the team working improves the subjective human operator Know-how-to-cooperate when controlling the autonomous shuttles. Moreover, the results showed that in addition to the work organization, other personal parameters, such as the frequency of playing video games could affect the performance and state of the human operator. They raised the importance of further analysis to determine cooperative patterns in a group of humans that can be adapted to improve human-machine cooperation.
Researcher Performance in Scopus Articles (RPSA) as a New Scientometric Model of Scientific Output: Tested in Business Area of V4 Countries
Authors: Krajcsák Zoltán
Published: October 2021

The purpose of this study is to present a new scientometric model for measuring individual scientific performance in Scopus article publications in the field of Business, Management, and Accounting (BMA). With the help of this model, the study also compares the publication performance of the top 50 researchers according to SciVal in the field of BMA, in each of the Central European V4 countries (Czech Republic; Hungary; Poland; Slovakia). To analyze the scientific excellence of a total of top 200 researchers in the countries studied, we collected and analyzed the data of a total of 1844 partially redundant and a total of 1492 cleansed BMA publications. In the scope of the study, we determined the quality of the journals using SCImago, the individual contributions to the journal articles, and the number of citations using Scopus data. A comparison of individual performance, as shown by published journal articles, can be made based on the qualities of the journals, the determination of the aggregated co-authorship ratios, and the number of citations received. The performance of BMA researchers in Hungary lags behind the average of V4s in terms of quantity, but in terms of quality it reaches this average. As for BMA journal articles, the average number of co-authors is between two and three; concerning Q4 to Q2 publications, this number typically increases. In fact, in the case of these Q journals multiple co-authorship results in higher citations, but it is not the case concerning Q1 journals.
Analysis of Temporal and Spatial Characteristics of Urban Expansion in Xiaonan District from 1990 to 2020 Using Time Series Landsat Imagery
Authors: Liu Yan , Zuo Renguang , Dong Yanni
Published: October 2021

With the rapid development in the global economy and technology, urbanization has accelerated. It is important to characterize the urban expansion and determine its driving force. In this study, we used the Xiaonan District in Hubei Province, China, as an example to map and quantify the spatiotemporal dynamics of urban expansion from the two perspectives of built-up area and urban land in 1990–2020 by using remote sensing images. The location of rivers was found to be a primary limiting factor for spatial patterns and expansion of the built-up area. The transfer of the city center and the main direction of expansion generally corresponded well to the topography, policies, and development strategies. The built-up area expanded faster than the urban population in 1995–2020, which caused a waste in land resources. The results showed that the urban expansion first decreased and then increased during the research period. The increase in the proportion of the secondary industry was the main driving force of the urban expansion. Based on the characteristics of urban expansion in the past three decades, we conclude that the urban land of Xiaonan District will expand quickly in the future and will occupy vast agricultural land. The government must deploy control measures to balance the benefits and costs of urban expansion.

Published: October 2021

Typhoon Goni crossed several provinces in the Philippines where agriculture has high socioeconomic importance, including the top-3 provinces in terms of planted coconut trees. We have used a computational model to infer coconut tree density from satellite images before and after the typhoon’s passage, and in this way estimate the number of damaged trees. Our area of study around the typhoon’s path covers 15.7 Mha, and includes 47 of the 87 provinces in the Philippines. In validation areas our model predicts coconut tree density with a Mean Absolute Error of 5.9 Trees/ha. In Camarines Sur we estimated that 3.5 M of the 4.6 M existing coconut trees were damaged by the typhoon. Overall we estimated that 14.1 M coconut trees were affected by the typhoon inside our area of study. Our validation images confirm that trees are rarely uprooted and damages are largely due to reduced canopy cover of standing trees. On validation areas, our model was able to detect affected coconut trees with 88.6% accuracy, 75% precision and 90% recall. Our method delivers spatially fine-grained change maps for coconut plantations in the area of study, including unchanged, damaged and new trees. Beyond immediate damage assessment, gradual changes in coconut density may serve as a proxy for future changes in yield.
A Flexible Region of Interest Extraction Algorithm with Adaptive Threshold for 3-D Synthetic Aperture Radar Images
Authors: Li Liang , Zhang Xiaoling , Tian Bokun , Wang Chen , Pu Liming , Shi Jun , Wei Shunjun
Published: October 2021

Most of the existing image segmentation methods have a strong anti-noise ability but are susceptible to the interference in the background, so they are not suitable for 3-D synthetic aperture radar (SAR) image target extraction. Region of interest (ROI) extraction can improve the anti-interference ability of the image segmentation methods. However, the existing ROI extraction method uses the same threshold to process all the images in the data set. This threshold is not optimal for each image. Designed for 3-D SAR image target extraction, we propose an ROI extraction algorithm with adaptive threshold (REAT) to enhance the anti-interference ability of the existing image segmentation methods. The required thresholds in the proposed algorithm are adaptively obtained by the mapping of the image features. Moreover, the proposed algorithm can easily be applied to existing image segmentation methods. The experiments demonstrate that the proposed algorithm significantly enhances the anti-interference ability and computational efficiency of the image segmentation methods. Compared with the existing ROI extraction algorithm, the proposed algorithm improves the dice similarity coefficient by 6.4%.

Published: October 2021

Optimization and sensitivity analysis of the kinetic parameters of the catalytic ozonation process is crucial to improve water treatment, reactor design, and construction. This study evaluated the optimization of the kinetic constants for Diclofenac (DCF) degradation during catalytic ozonation with Goethite (FeOOH, as a catalyst) through different kinetic modeling approaches. A central composite design was used to evaluate the effect of ozone dose and catalyst loading. The results showed that FeOOH did not significantly influence the degradation of DCF, while the reactivity of DCF with ozone was high (with >90% degradations in 20 min). However, the variation in catalyst loading significantly affected TOC removal (>10%) and ozone use, with ozone efficiency in ozone transfer (RU) 5% higher than ozonation. After evaluating the different kinetic models of reaction speed by optimizing kinetic parameters and performing sensitivity analysis for the treatment of DCF by catalytic ozonation, it can be concluded that the addition of FeOOH improved the kinetics of the decomposition of ozone and the yield in the production of hydroxyl radicals.

Published: October 2021

Predictive models of bathing water quality are a useful support to traditional monitoring and provide timely and adequate information for the protection of public health. When developing models, it is critical to select an appropriate model type and appropriate metrics to reduce errors so that the predicted outcome is reliable. It is usually necessary to conduct intensive sampling to collect a sufficient amount of data. This paper presents the process of developing a predictive model in Kaštela Bay (Adriatic Sea) using only data from regular (official) bathing water quality monitoring collected during five bathing seasons. The predictive modelling process, which included data preprocessing, model training, and model tuning, showed no silver bullet model and selected two model types that met the specified requirements: a neural network (ANN) for Escherichia coli and a random forest (RF) for intestinal enterococci. The different model types are probably the result of the different persistence of two indicator bacteria to the effects of marine environmental factors and consequently the different die-off rates. By combining these two models, the bathing water samples were classified with acceptable performances, an informedness of 71.7%, an F-score of 47.1%, and an overall accuracy of 80.6%.

Aprendizagem do medo por observação em pombos (Columba livia)
Authors: Pelaquim Andressa , Canova Fernando Bicocchi , Ferrari Elenice Aparecida de Moraes
Published: October 2021

Introdução. Estudos com roedores e primatas demonstram que a aprendizagem do medo ocorre por experiência com contingências aversivas ou por observação da experiência de outros. Objetivo. Analisar a aquisição da resposta condicionada de medo por pombos que observaram o treino de condicionamento clássico som-choque em um animal modelo. Método. Pombos, machos, adultos, (Columba livia), atribuídos aos grupos: Grupo Modelo e Grupo Observação. O procedimento experimental foi conduzido com pombos treinados (modelo) e pombos observadores. Os grupos, foram expostos ao treino com três pareamentos som-choque, seguido pelo teste ao contexto 24h depois e teste ao som, 48h depois. As sessões foram gravadas para transcrição e análise de comportamentos. Os dados comportamentais foram analisados com o teste ANOVA e com o teste Tukey para comparações post hoc. Resultados. Os Grupos Modelo e Observação foram caracterizados por apresentação de congelamento, comportamento tipicamente estudado em trabalhos que envolvam aprendizagem aversiva. Verificou-se o mesmo padrão de comportamentos para os pombos Modelos e Observadores, o que indica que a experiência de observar outro pombo durante o treino aversivo resultou em comportamentos condicionados de medo, demonstrando aprendizagem de medo por observação em pombos. Conclusão. Esses dados corroboram com resultados obtidos em primatas e roedores

Published: October 2021

Kanatlı hayvanlarda büyüme ve yumurta verimlerinin modellenmesinde çoğunlukla tek evreli doğrusal olmayan regresyon eşitlikleri kullanılmış, sınırlı sayıda çalışmada ise söz konusu özellikler çok evreli fonksiyonlarla modellenmiştir. Bu çalışmada kanatlı hayvanlarda büyümenin modellenmesi amacıyla çok evreli büyüme modeli üzerinde durulmuş ve modelin tanıtılması amaçlanmıştır. Bu amaçla bir damızlık hindi sürüsünde erkek ve dişi bireylere ait 60 haftalık canlı ağırlık verileri kullanılarak çok evreli lojistik fonksiyon ile büyüme modellenmiştir. Model uyumu oldukça yüksek bulunmuş, belirleme katsayıları dişilerde ve erkeklerde, sırasıyla 0,999 ve 0,998 olarak elde edilmiştir. Modelin a parametresi asimptotik ağırlığın yarısını, k parametresi ortalama büyüme hızını, c parametresi en yüksek büyüme hızının gerçekleştiği haftayı temsil etmektedir. İki evreli modelde; dişi hindiler için model parametreleri olan ɑ1, k1, c1, ɑ2, k1 ve c2 için tahmin edilen değerler sırası ile 2475,9, 0,367, 11,64, 4035,4, 0,969 ve 36,53 olarak bulunmuştur. Erkek hindilere ait ɑ1, k1, c1, ɑ2, k1 ve c2 parametrelerinin tahmin edilen değerleri ise sırası ile 3336,6, 0,399, 13,99, 5598,9, 0,467 ve 31,26 olarak elde edilmiştir. Sonuç olarak gerek belirleme katsayısı gerekse bilgi kriterlerine göre, dişi ve erkek hindilerin büyüme verilerine uydurulan iki evreli model tek evreli modele göre daha yüksek bir başarı göstermiştir.

We aimed to analyze the management of children with Jervell-Lange-Nielsen syndrome based on their clinical and genetic characteristics and to assess the effectiveness of their therapy.

Methods. We analyzed medical data from 12 Jervell and Lange-Nielsen syndrome patients. Mean follow-up was 8.3±5.1 years. Comprehensive cardiological examination include the standard 12-lead electrocardiography (ECG), echocardiography, stress-test, 24-hour Holter recordings, blood tests, thyroid ultrasound, and assessment of thyroid hormone levels, and if necessary, consultation with a neurologist.

Results. At the first visit, the mean age was 3.0±2 years old, girls prevailed (67%). All patients are alive now. The mean QTc was 578.9±57.3 ms. Cardiac events had 10 patients (83%), mean age at the first event was 1.9±1.6 years. In 67% of children, syncope was initially regarded as epileptic. All patients received beta-blockers, which were prescribed at mean age 3.0±2.3 years (from 1 month to 7 years). In 8 patients cardiac events recurred despite regular and adequate beta-blocker therapy, all of them were implanted with implanted cardioverter-defibrillator. It was found that patients with the first syncope under the age of 1.5 and delayed initiation of therapy (at the mean age 4.3±1.7 years) had multiple recurrences of syncope despite therapy. Non-cardiac symptoms include sensorineural hearing loss in 100% of cases and hypochromic anemia in 75% of cases.

Conclusion. In Jervell-Lange-Nielsen patients who are characterized by resistant ventricular tachyarrhythmia aggressive antiarrhythmic therapy at a very early age is essential for increasing the risk of life-threatening cardiac events. Consequently, diagnosis of the disease in the first days of life is extremely relevant. ECG screening is crucial in solving the problem of early diagnosis of the disease. Extracardiac pathology in patients with Jervell-Lange-Nielsen syndrome necessitates the interaction of doctors of different specialties together when managing a patient.

RELATIONSHIP OF ACCEPTABILITY OF MISLEADING METHODS WITH PERSONAL FEATURES AND SOCIAL BEHAVIOR STRATEGIES
Authors: Vikhman A.A.
Published: October 2021

The article presents the results of an empirical study of personality traits, strategies of social behavior and the acceptability of information manipulation on a sample of youth, mainly female students (n=195). Based on the theory of communicative implicatures by P. Grice and the theory of information manipulation by S. McCornack, a case test with educational and interpersonal situations of communication was created, aimed at studying the choice of admissibility of information manipulation. Correlation analysis revealed that the acceptability of all four forms of information manipulation (lies, deception, inappropriateness, and obscurity) is most closely related to deficiencies in conscientiousness (lack of productivity, organization, and responsibility) and goodwill (lack of trust and empathy). We can observe the connections with individual personality aspects that are unique for different methods of information manipulation. In addition, information manipulation is associated with destructive social strategies of behavior, especially in the intersubjective sphere and in combination with a tendency to devalue the interlocutor.

presença de midrashim em crônicas de Natal de Clarice Lispector
Authors: Botler Laís Maria Rosal , Baumworcel Rodrigo
Published: October 2021

O judaísmo nunca aparece de maneira explícita na literatura de Clarice Lispector. No entanto, como demonstram Gilda Szklo (1989), Nelson Vieira (1989) e Berta Waldman (2011; 2014), a influência judaica pode ser percebida de diferentes formas na escrita de Clarice. Neste trabalho, analisaremos a presença de midrashim na representação do Natal nas crônicas “Anunciação”, “A virgem em todas as mulheres”, “Ele seria alegre” e “A humildade de São José”.
Moacyr Scliar
Authors: Santos Márcio César Pereira dos
Published: October 2021

O judaísmo e a tradição judaica, a revisão histórica, o discurso da ciência, as Escrituras, a memória e a identidade latino-americana, são algumas das linhas temáticas que conformam trama e novelo da obra multifacetada de Moacyr Scliar. A integração de todos esses discursos no jogo infinito da ficção revela a sofisticada teia literária tecida pelo escritor. Não seria diferente quando o autor lida com um mito tão cheio de nuances, como o Golem. Esta comunicação analisará a retomada desse mito, explicitamente, em dois livros de Scliar, de forma literal no romance Cenas da vida minúscula, publicado em 2003, e, obliquamente, em Manual da paixão solitária, de 2008.
comida e as dores da memória na obra de Halina Grynberg
Authors: Mota Sandra de Almada
Published: October 2021

Halina Grynberg, no romance Mameloshn: memória em carne viva, 2004, trata da dor imposta por lembranças e dos traumas que atravessam gerações passando, certamente, pela alimentação. Nesse relato, a narrativa transporta o leitor para memórias afetivas que antes inquietam que confortam. De forma semelhante, em O padeiro polonês, 2005, a escritora articula a memória sofrida à preparação da chalá, o pão trançado, feito pelo pai da narradora. Percebe-se que a comida, nesses dois romances autobiográficos, possui uma linguagem temperada com lágrimas e múltiplas significações.
