Authors: Wufuer Rehemanjiang , Duo Jia , Pei Liang , Wang Shuzhi , Li Wenfeng
Published: May 2023

In recent years, polybutylene adipate-co-terephthalate (PBAT) mulch film has become one of the most commonly used biodegradable mulch films in agriculture in an attempt to combat plastic film pollution. However, its degradation characteristics and impact on the soil environment and crop growth are affected by many factors such as its composition, soil and crop types, local climate characteristics, etc. In this study, PBAT mulch film and ordinary polyethylene (PE) film were used as test materials, with non-mulching treatment (CK) as a control, to study the applicability of PBAT film in Moyu County, Southern Xinjiang region, using tomato growth as an example. The results showed that PBAT film started its induction period after 60 days, and 60.98% of the PBAT film was degraded within 100 days. Generally, the soil temperature and humidity preservation functions of this film were comparable to that of PE film in the seedling and flowering–fruiting stages of tomato growth. In the mature stage, the soil humidity under PBAT film was significantly lower than that of PE film due to its substantial degradation rate. However, this did not have any significant negative effects on tomato growth, yield, and quality. The tomato yield of 667 m2 with BPAT was insignificantly lower than that of PE film by 3.14%, and both were significantly higher than that of the CK treatment by 63.38% and 68.68%, respectively, indicating that it is feasible to use PBAT film to cultivate crops such as tomato in the arid region of Southern Xinjiang, China.

Fescue toxicosis is caused by grazing ergot alkaloid-producing endophyte (Epichloë coenophiala)-infected tall fescue (E+). Summer grazing of E+ leads to decreased productivity, associated impaired thermoregulation, and altered behavior. The goal of this study was to determine the role of E+ grazing-climate interaction on animal behavior and thermoregulation during late fall. Eighteen Angus steers were placed on nontoxic (NT), toxic (E+) and endophyte-free (E−) fescue pastures for 28 days. Physiological parameters, such as rectal temperature (RT), respiration rate (RR), ear and ankle surface temperature (ET, AT), and body weights, were measured. Skin surface temperature (SST) and animal activity were recorded continuously with temperature and behavioral activity sensors, respectively. Environmental conditions were collected using paddocks-placed data loggers. Across the trial, steers on E+ gained about 60% less weight than the other two groups. E+ steers also had higher RT than E− and NT, and lower SST than NT post-pasture placement. Importantly, animals grazing E+ spent more time lying, less time standing, and took more steps. These data suggest that late fall E+ grazing impairs core and surface temperature regulation and increases non-productive lying time, which may be partly responsible for the observed decreased weight gains.

A status report is presented about the Nanoplasmonic Laser Induced Fusion Experiment (NAPLIFE). The goal is to investigate and verify plasmonically enhanced phenomena on the surfaces of nanoantennas embedded in a polymer target at laser intensities up to a few times 1016 W/cm2 and pulse durations of 40–120 fs. The first results on enhanced crater formation for Au-doped polymer targets are shown, and SERS signals typical for CD2 and ND bound vibrations are cited. Trials to detect D/H ratio by means of LIBS measurments are reported. Plasmonics has the potential to work at these intensities, enhancing the energy and deuterium production, due to thus far unknown mechanisms.
Derivation of Emergent Spacetime Metric, Gravitational Potential and Speed of Light in Superfluid Vacuum Theory
Authors: Zloshchastiev Konstantin G.
Published: May 2023

Within the frameworks of the logarithmic superfluid model of physical vacuum, we demonstrate the emergence of four-dimensional curved spacetime from the dynamics of quantum Bose liquid in three-dimensional Euclidean space. We derive the metric tensor of this spacetime and study its special cases and limits, such as the linear-phase flow and linearized gravity limit. We show that the value of speed of light, which is a fundamental parameter in a theory of relativity, is a derived notion in superfluid vacuum theory: its value is a combination of the Planck constant and original parameters of the background superfluid. As for the gravitational potential, then it can be defined in terms of the quantum information entropy of the background superfluid. Thus, relativistic gravity and curved spacetime are shown to result from the dynamics of quantum excitations of the background superfluid being projected onto the measurement apparatus of a relativistic observer.
Simulations on Synchrotron Radiation Intensity and Rotation Measure of Relativistic Magnetized Jet PKS 1502+106
Authors: Chang Che-Jui , Kiang Jean-Fu
Published: May 2023

Strong γ-ray outbursts have been observed to emanate from PKS 1502+106, followed by highly variable fluxes in radio, visual, ultraviolet and X-ray bands. Numerical simulations have been conducted to relate the observations to potential theoretical models. The plasma attributes, such as mass density, plasma flow velocity and energy density, cannot be directly observed. However, the Stokes parameters of synchrotron radiation from the plasma can be measured to deduce the plasma attributes. Many studies have been conducted on synchrotron radiation intensity, with only a few on the rotation measure (RM) related to Faraday rotation. In this work, overpressured relativistic magnetized axisymmetric jets are simulated to acquire the synchrotron radiation maps, incorporating Faraday rotation, of the widely discussed jet, PKS 1502+106. The intensity maps and RM maps of the PKS 1502+106 are simulated under practical constraints, and compared with the available observation data to explore specific features of the jet. The simulated intensity maps match well with the observation data in size and shape. The observed spine–sheath polarization structure, sign change in the RM slice and opposite RM gradients have been reproduced. The conjecture of helical magnetic field morphology in the literature has also been validated by comparing the simulation results under different magnetic field morphologies.

Published: May 2023

The study of massive neutrinos and their interactions is a critical aspect of contemporary cosmology. Recent advances in parallel computation and high-performance computing provide new opportunities for accurately constraining Large-Scale Structures (LSS). In this paper, we introduce the TianNu cosmological N-body simulation during the co-evolution of massive neutrino and cold dark matter components via the CUBEP3M code running on the supercomputer Tianhe-2 and TianNu’s connected works. We start by analyzing 2.537×107 dark halos from the scientific data of TianNu simulation, and compare their angular momentum with the matched halos from neutrino-free TianZero, revealing a dependence of angular momentum modulus on neutrino injection at scales below 50 Mpc and around 10 Mpc.
Nontrivial Topology Dynamical Corrections and the Magnetic Monopole-like Effect in Minkowski Spacetime
Authors: Hoff da Silva Julio Marny , Cavalcanti Rogerio Teixeira
Published: May 2023

We investigate two physical systems within a spacetime region affected by the nontrivial topology. The set-up for our analysis is a Minkowski metric perturbed by elements reflecting the topological nontriviality. These elements arise when exploring Cartan’s spinorial approach along with the exotic spinors counterpart. This evinced nontrivial topology corrections in the free particle dynamics and charged particles coupled to an external electromagnetic field. As a complement, we show the appearance of a magnetic monopole-like effect.

The ability of the HIV-1 accessory proteins Nef and Vpu to decrease CD4 levels contributes to the protection of infected cells from antibody-dependent cellular cytotoxicity (ADCC) by preventing the exposure of Env vulnerable epitopes. Small-molecule CD4 mimetics (CD4mc) based on the indane and piperidine scaffolds such as (+)-BNM-III-170 and (S)-MCG-IV-210 sensitize HIV-1-infected cells to ADCC by exposing CD4-induced (CD4i) epitopes recognized by non-neutralizing antibodies that are abundantly present in plasma from people living with HIV. Here, we characterize a new family of CD4mc, (S)-MCG-IV-210 derivatives, based on the piperidine scaffold which engages the gp120 within the Phe43 cavity by targeting the highly conserved Asp368 Env residue. We utilized structure-based approaches and developed a series of piperidine analogs with improved activity to inhibit the infection of difficult-to-neutralize tier-2 viruses and sensitize infected cells to ADCC mediated by HIV+ plasma. Moreover, the new analogs formed an H-bond with the α-carboxylic acid group of Asp368, opening a new avenue to enlarge the breadth of this family of anti-Env small molecules. Overall, the new structural and biological attributes of these molecules make them good candidates for strategies aimed at the elimination of HIV-1-infected cells.
Idiotope-Driven T-Cell/B-Cell Collaboration-Based T-Cell Epitope Prediction Using B-Cell Receptor Repertoire Sequences in Infectious Diseases

Published: May 2023

T-cell recognition of antigen epitopes is a crucial step for the induction of adaptive immune responses, and the identification of such T-cell epitopes is, therefore, important for understanding diverse immune responses and controlling T-cell immunity. A number of bioinformatic tools exist that predict T-cell epitopes; however, many of these methods highly rely on evaluating conventional peptide presentation by major histocompatibility complex (MHC) molecules, but they ignore epitope sequences recognized by T-cell receptor (TCR). Immunogenic determinant idiotopes are present on the variable regions of immunoglobulin molecules expressed on and secreted by B-cells. In idiotope-driven T-cell/B-cell collaboration, B-cells present the idiotopes on MHC molecules for recognition by idiotope-specific T-cells. According to the idiotype network theory formulated by Niels Jerne, such idiotopes found on anti-idiotypic antibodies exhibit molecular mimicry of antigens. Here, by combining these concepts and defining the patterns of TCR-recognized epitope motifs (TREMs), we developed a T-cell epitope prediction method that identifies T-cell epitopes derived from antigen proteins by analyzing B-cell receptor (BCR) sequences. This method allowed us to identify T-cell epitopes that contain the same TREM patterns between BCR and viral antigen sequences in two different infectious diseases caused by dengue virus and SARS-CoV-2 infection. The identified epitopes were among the T-cell epitopes detected in previous studies, and T-cell stimulatory immunogenicity was confirmed. Thus, our data support this method as a powerful tool for the discovery of T-cell epitopes from BCR sequences.

Published: May 2023

Human adenovirus 55 (HAdV-55) has recently caused outbreaks of acute respiratory disease (ARD), posing a significant public threat to civilians and military trainees. Efforts to develop antiviral inhibitors and quantify neutralizing antibodies require an experimental system to rapidly monitor viral infections, which can be achieved through the use of a plasmid that can produce an infectious virus. Here, we used a bacteria-mediated recombination approach to construct a full-length infectious cDNA clone, pAd55-FL, containing the whole genome of HadV-55. Then, the green fluorescent protein expression cassette was assembled into pAd55-FL to replace the E3 region to obtain a recombinant plasmid of pAd55-dE3-EGFP. The rescued recombinant virus rAdv55-dE3-EGFP is genetically stable and replicates similarly to the wild-type virus in cell culture. The virus rAdv55-dE3-EGFP can be used to quantify neutralizing antibody activity in sera samples, producing results in concordance with the cytopathic effect (CPE)-based microneutralization assay. Using an rAdv55-dE3-EGFP infection of A549 cells, we showed that the assay could be used for antiviral screening. Our findings suggest that the rAdv55-dE3-EGFP-based high-throughput assay provides a reliable tool for rapid neutralization testing and antiviral screening for HAdV-55.
Quantitative Mutation Analysis of Genes and Proteins of Major SARS-CoV-2 Variants of Concern and Interest
Authors: Liang Fengyi
Published: May 2023

Of various SARS-CoV-2 variants, some have drawn special concern or interest because of their heightened disease threat. The mutability of individual SARS-CoV-2 genes/proteins presumably varies. The present study quantified gene/protein mutations in 13 major SARS-CoV-2 variants of concern/interest, and analyzed viral protein antigenicity using bioinformatics. The results from 187 carefully perused genome clones showed significantly higher mean percent mutations in the spike, ORF8, nucleocapsid, and NSP6 than in other viral proteins. The ORF8 and spike proteins also tolerated higher maximal percent mutations. The omicron variant presented more percent mutations in the NSP6 and structural proteins, whereas the delta featured more in the ORF7a. Omicron subvariant BA.2 exhibited more mutations in ORF6, and omicron BA.4 had more in NSP1, ORF6, and ORF7b, relative to omicron BA.1. Delta subvariants AY.4 and AY.5 bore more mutations in ORF7b and ORF8 than delta B.1.617.2. Predicted antigen ratios of SARS-CoV-2 proteins significantly vary (range: 38–88%). To overcome SARS-CoV-2 immune evasion, the relatively conserved, potentially immunogenic NSP4, NSP13, NSP14, membrane, and ORF3a viral proteins may serve as more suitable targets for molecular vaccines or therapeutics than the mutation-prone NSP6, spike, ORF8, or nucleocapsid protein. Further investigation into distinct mutations of the variants/subvariants may help understand SARS-CoV-2 pathogenesis.
Canocapavir Is a Novel Capsid Assembly Modulator Inducing a Conformational Change of the Linker Region of HBV Core Protein

Published: May 2023

Canocapavir is a novel antiviral agent with characteristics of core protein allosteric modulators (CpAMs) that is currently in a phase II clinical trial for treatment of hepatitis B virus (HBV) infection. Herein, we show that Canocapavir prevented the encapsidation of HBV pregenomic RNA and increased the accumulation of cytoplasmic empty capsids, presumably by targeting the hydrophobic pocket at the dimer-dimer interface of HBV core protein (HBc). Canocapavir treatment markedly reduced the egress of naked capsids, which could be reversed by Alix overexpression through a mechanism other than direct association of Alix with HBc. Moreover, Canocapavir interfered with the interaction between HBc and HBV large surface protein, resulting in diminished production of empty virions. Of particular note, Canocapavir induced a conformational change of capsids, with the C-terminus of HBc linker region fully exposed on the exterior of capsids. We posit that the allosteric effect may have great importance in the anti-HBV activity of Canocapavir, given the emerging virological significance of HBc linker region. In support of this notion, the mutation at HBc V124W typically recapitulated the conformational change of the empty capsid with aberrant cytoplasmic accumulation. Collectively, our results indicate Canocapavir as a mechanistically distinct type of CpAMs against HBV infection.

Published: May 2023

The role of veterinarians is becoming more significant and necessary to support the welfare and health not only of non-traditional companion animals and wildlife animals, but also of humans and the environment. The importance of the One Health/One World concept and its social impact is increasing significantly, accompanied by the notoriety of new emerging and reemerging zoonoses. This paper aims to review and anchor the main concepts and professional applications of zoological medicine, which has been extensively discussed and adapted in recent decades. In addition, we analyse the main social demands, training, and educational needs and the perception of veterinary professionals relating to this specialised veterinary discipline. Our final goal is to reinforce the use of the term zoological medicine and contribute to highlight the need to foster and underpin specific educational policies and programs on this matter in the veterinary curricula. Zoological medicine should be the appropriate and agreed-upon term in the academic language concerning the veterinary medicine of pets, wild, or zoo species, excluding traditional domestic animals, and integrating the principles of ecology and conservation, applied to both natural and artificial environments. This discipline has suffered an intense evolution covering applications in private clinics, zoos, bioparks, and wildlife. All this implies current and future challenges for the veterinary profession that can only be addressed with greater and better attention from multiple perspectives, especially the education and training of professionals to improve and specialise in their professional scope of services.
How to Minimize the Environmental Contamination Caused by Hydrocarbon Releases by Onshore Pipelines: The Key Role of a Three-Dimensional Three-Phase Fluid Flow Numerical Model
Authors: Feo Alessandra , Pinardi Riccardo , Scanferla Emanuele , Celico Fulvio
Published: May 2023

The contamination impact and the migration of the contaminant into the surrounding environment due to the presence of a spilled oil pipeline will cause significant damage to the natural ecosystem. For this reason, developing a rapid response strategy that might include accurate predictions of oil migration trajectories from numerical simulation modeling is decisive. This paper uses a three-dimensional model based on a high-resolution shock-capturing conservative method to resolve the nonlinear governing partial differential equations of the migration of a spilled light nonaqueous liquid oil contaminant in a variably saturated zone employed to investigate the migration of the oil pipeline leakage with great accuracy. The effects of the oil type density, gasoline, and diesel oil, the unsaturated zone depth, its saturation, the hydraulic gradient, and the pressure oil pipeline are investigated through the temporal evolution of the contaminant migration following the saturation profiles of the three-phase fluid flow in the variably saturated zone. The calculation results indicate that the leaking oil’s pressure is the parameter that significantly affects the contaminants’ arrival time at the groundwater table. Additionally, the water saturation of the unsaturated zone influences the arrival time, as the water saturation increases at a fixed depth. The unsaturated zone depth significantly influences the contaminant migration in the unsaturated zone. At the same time, the oil density and the hydraulic gradient have limited effects on the contaminant migration in the variably saturated zone.
Removal and Reclamation of Trace Metals from Copper and Gold Mine Tailing Leachates Using an Alkali Suspension Method

Published: May 2023

Leachates from mine tailing ponds, which usually contain a variety of metallic ions, are highly toxic to human and ecological health. The common methods used to remove those trace metallic are difficult due to the extremely acidic conditions and the diverse kinds of metals in mine tailing leachates. Herein, we proposed an economical and efficient soil-assisted alkali suspension approach to remove and reclaim the trace metals. Under the optimum conditions, more than 98% of Cu2+, Zn2+, and Cr3+, and 93% of Cd2+ were removed from authentic copper and gold tailing leachates. Multiple characterizations indicated that the quick removal of trace metal ions from leachates was mainly due to the formation of amorphous hydroxides which are easily adsorbed by soil particles. Additionally, small quantities of metal ions and organic matter complexes were formed, which contributed to the removal of trace metals. Furthermore, most of the adsorbed trace metal in authentic tailing leachate can be reclaimed by a simple acid treatment. Life cycle assessment analysis demonstrated the environmental sustainability of this alkali suspension method due to its smaller contribution to global warming. This study provides an efficient and low-cost approach for the disposal and recycling of toxic mine tailing leachates.

Published: May 2023

A novel two-hybrid optimization model of particle swarm optimization (FAPSO) and firefly algorithm with genetic algorithm (FAGA) are introduced to improve the performance of the conventional firefly algorithm for the least cost design of water distribution networks. The performance of the models is tested through application to three of the well-known benchmark networks available in the literature and also to the real case study of the El-Mostakbal City network, Ismailia, Egypt. The performance of the different algorithms was determined by evaluating the minimum, maximum, mean and standard deviation of costs, the function evaluation number, the consumed computational time for 1000 evaluations and the success rate calculated using the fuzzy logic concept for different optimal solutions slightly greater than the known optimal solution (by about 1.0% and 2.0%) were utilized for testing the convergence and search capabilities of the models. It was found that the FAGA model is superior to the standard firefly and FAPSO models in exploring the search space, exploiting the promising areas and convergence to the optimal solution and can be considered as a reasonable optimization technique for the management of water distribution networks.

Published: May 2023

High-rate algal ponds (HRAPs) are a highly promoted wastewater treatment system that uses sunlight as an energy source to provide the oxygen needed in the system through photosynthesis and has a high nutrient and organic matter removal capacity. In addition, the microalgae in the system can use wastewater as a growth substrate to produce valuable bioproducts, biomaterials, and bioenergy, so it is receiving more and more attention. This review uses bibliometric analysis to explore current research hotspots and future research trends in this emerging technology. By analyzing research papers related to HRAPs published in the Web of Science (WOS) from 1987 to 2021 based on the co-occurrence and clustering of keywords, it shows that the research hotspots of HRAPs are mainly focused on wastewater treatment, nutrient removal, microalgal biomass, biofuel, and biogas upgrading. In the future, in-depth research will continue to be added on the contribution of HRAPs to environmental sustainability, including E. coli removal, biogas upgrading and oxygen removal, treatment of aquaculture wastewater, purple phototrophic bacteria, aqueous biorefineries, and biorefineries. The results assist scholars in systematically understanding the current research status, research frontiers, and future trends of HRAPs from a macro perspective.

Published: May 2023

Young women from urban Egypt are in a context of nutrition transition with a high prevalence of being overweight, excessive energy and sodium intakes, and insufficient iron, vitamin D, and folate intakes. This study, funded by Danone Nutricia Research, investigated the acceptability of dietary recommendations in young urban Egyptian women that have the potential to improve iron intake and nutrient adequacy. Individual interviews and focus groups were conducted in Cairo with 80 middle-class women aged 18–35 years (students, active women, and housewives). Perceived benefits and drawbacks for each recommended food were examined. Motivations and barriers to improving dietary practices were classified into major emerging themes. Analysis of the interviews showed that promoting the recommended foods would be met with both positive and negative feedback (e.g., a positive impact of fruit, vegetables, milk, or yogurt consumption on hair, nails, and skin appearance, and bad taste of vegetables). Motivations for improving dietary practices included the pursuit of aesthetical (e.g., attaining/maintaining body shape, clear skin, bright teeth, strong nails, silky and thick hair) and psychological (e.g., improved self-confidence and self-esteem) benefits. However, the “curative behavior” of the population targeted (i.e., changing dietary practices only when they face a serious issue), some life-stage-related factors (e.g., students and active women consuming most of their meals out-of-home), and sociocultural and economic factors (e.g., social gatherings, the high price of red meat) can constitute barriers for implementing a set of dietary recommendations. This work highlighted that, beyond socio-cultural and economic factors or curative or life-stage-motivated dieting, the pursuit of aesthetical and psychological benefits are essential factors that shape the acceptability of dietary changes.
Effects of Playing Music during PE on Intrinsic Motivation of Students
Authors: Cools Wouter , De Frère Ulrike , Caplin Ariane
Published: May 2023

The aim of this study was to investigate whether playing music during PE lessons had an impact on the intrinsic motivation of high school students, including enjoyment, competency, freedom of choice and stress. Using a mixed method approach, intrinsic motivation of 40 students (25 girls, 15 boys) was surveyed. The Intrinsic Motivation Inventory was combined with a focus group discussion to collect pupils’ and teacher’s perceptions. Data analysis showed motivation scores to be significantly better during PE with music than PE without music. This difference was also reflected for joy or interest, with pupils experiencing more joy during PE with music. Students reported feeling more enthusiastic with music, which gave them more energy; they participated with higher motivation and had more fun. In addition, the combination of increased concentration and self-confidence resulted in higher competence scores during PE with music. No significant differences were found for freedom of choice and stress in either condition. It can be concluded that playing music during PE positively influences students’ intrinsic motivation. More specifically, the influence of music is mainly found in increased students’ perception of enjoyment, interest and sense of competence. The findings of this study should be the impetus for PE teachers to implement music more often.
The Ternary Object: On Shinichiro Kurimoto’s Theory of Levels
Authors: Tateyama Toshiharu , Mikado Naruhiko
Published: May 2023

This brief article has two objectives. First, it aims to provide a concise and lucid elucidation of Theory of Levels, an ontological system which the veteran Japanese thinker Shinichiro Kurimoto first invented in the early 1980s and has ever refined through the course of his decades-long career. Second, it intends to demonstrate with cogency that the discourse, albeit having been buried in oblivion for quite a while, carries a potential to help one to obtain a new perspective from which to freshly and positively interpret the existential dilemma between our natural sense that each one of us is a unique existence and the sheer reality that every one of us is merely a trivial strand of diverse larger structures.

In order to achieve the objects, the argumentation proceeds in the following　order. Taking a survey of the papers in which Kurimoto’s Theory of Levels makes an appearance, the initial part confirms that, though it fis not the case that all academicians have completely disregarded the theory, as yet none of them has conducted a sufficiently comprehensive dissection thereof. Consulting, or rather reconstructing Kurimoto’s laconic account in his 2013 booklet entitled The Last Lecture of Shinichiro Kurimoto, the second part clarifies that the theoretical singularity of Theory of Levels consists in that it enables one to deem an existence to be a ternary object and thereby to get over the apparently insuperable quandary mentioned above. The third part concludes the discussion by indicating that decades after Kurimoto some researchers in natural science come to discuss from their own scientific perspective some views that hold a quite high degree of intimacy with Kurimoto’s theory. The authors of this paper are fully convinced that the Theory of Levels and/or fields upheld by the researchers

mentioned in this paper are worth academic efforts to be scrutinized to close in on the ontological essence of mankind and every other existence alike.

Acidentes com anuros contribuem para a casuística de emergências do cão doméstico e demandam conhecimento do médico veterinário. Objetiva-se nesse artigo discorrer sobre a intoxicação por bufotoxina através do relato de caso de um canino intoxicado. Um canino, macho, 2 anos, em estupor após contato com um anfíbio do gênero Bufo foi atendido em um Hospital Veterinário. Apresentava bradipneia, bradicardia, hipotensão, nistagmo horizontal, sialorreia e mucosas pálidas. Paciente recebeu 0,044 mg/kg de sulfato de atropina via intravenosa (IV), oxigenioterapia e foram monitorados os parâmetros vitais. A cavidade oral foi lavada com água e administrou-se carvão ativado.  Averiguou-se fibrilação no eletrocardiograma. Foi realizado lidocaína 2 mg/kg em bolus IV e aplicado dexametasona intramuscular em dose única de 0,5 mg/kg. O manejo da pressão arterial foi realizado através de fluidoterapia com ringer com lactato 10 ml/kg em 15 minutos. O paciente apresentava choque anafilático. A bradicardia justificou o sulfato de atropina e a lidocaína foi essencial para a normalização do ritmo cardíaco. Além disso, a fluidoterapia proporcionou normoesfigmia e a lavagem oral com água e o carvão ativado auxiliaram na redução da absorção da toxina. Obteve-se a resolução do quadro clínico em 3 horas. A sintomatologia é explicada pela ação das aminas biogênicas e os esteroides contidos nos venenos. O manejo da hemodinâmica e do choque foram essenciais para a resolução do quadro. Portanto, o conhecimento prévio sobre intercorrências em intoxicações por bufotoxina em cães é primordial para a escolha de uma melhor abordagem terapêutica para os pacientes.

Debido a su importancia, en los últimos años el estudio de las principales fuentes de innovación empresarial ha adquirido gran relevancia, si bien todavía existe cierta ambigüedad en relación con los principales factores que afectan a la generación y desarrollo de innovaciones. El principal objetivo de esta investigación es analizar la relación existente entre la orientación emprendedora de las empresas y su capacidad de innovación, así como el posible efecto mediador del capital social y la capacidad de absorción en esta relación. Para ello, se realiza un análisis empírico sobre una muestra de 197 empresas españolas del sector de suministro de energía eléctrica. Para realizar el análisis estadístico, se ha utilizado la técnica de modelización de ecuaciones estructurales basadas en la varianza (PLS-SEM) y, particularmente, el software “SmartPLS” en su versión 3.9. Los resultados desvelan que la orientación emprendedora de las empresas afecta de forma positiva y significativa a su capacidad para innovar. Además, el capital social y la capacidad de absorción se establecen como variables mediadoras en esta relación. Se concluye que las empresas pueden impulsar su capacidad de innovación favoreciendo el desarrollo de un clima emprendedor en la empresa, incentivando la participación de todos los miembros de la empresa en la identificación y explotación de oportunidades de negocio. Este clima puede favorecer el desarrollo de amplias redes de contactos valiosos, y la capacidad de absorción de nuevo conocimiento de la empresa lo cual, en última instancia, permitiría incrementar su capacidad de innovación.

Introdução: Este trabalho pretendeu relatar e demonstrar como funciona a malária dentro do organismo da vítima, sendo que esta consiste em uma patologia grave e infecciosa que causa febre crítica ao hospedeiro causada através de protozoários do gênero Plasmodium que precisam se estabelecer dentro das células (eritrócitos) para realizar seu ciclo biológico. É sabido ainda que existem quatros espécies deste protozoário que podem causar infecção aos seres humanos. São eles:  P. falciparum, P. vivax, P. malariae e P. ovale, e que seu principal vetor é o mosquito fêmea do gênero Anopheles. Objetivo: Sabendo disso, a presente proposta de pesquisa teve por objetivo demonstrar a importância do diagnóstico precoce enquanto pilar da saúde publica para o controle da malária, buscando assim esclarecer os diagnósticos que podem ser realizados para poder maximizar as chances de controle desta patologia, bem como seu tratamento. Metodologia: Este projeto buscou relatar uma abordagem com características qualitativa-exploratória-descritiva, usando dados e informações disponíveis na Bibliotecas e Periódicos da CAPES, Revistas Virtuais da SciELO e Biblioteca Virtual em Saúde (BVS), também em base de dados indexadas – de Farmácia além de acervo próprio e outras obras bibliográficas encontradas na internet. Resultados: Com estas informações adquiridas foi possível demonstrar como os   profissionais que atuam na assistência de saúde podem exercer melhor suas funções de forma  mais abrangente frente ao enfrentamento da malária com vistas à ampliação do cuidado à saúde através dos diagnósticos e que deste modo possa haver uma contribuição para que se melhore o conhecimento e tenha processos cada vez mais estruturados e fluidos. Considerações Finais: Contudo, tendo como embasamento estes conhecimentos sobre as ações de funcionamento da malária e seus agentes, uma realização de ações farmacêuticas foi buscada para que se visassem através do diagnostico uma prevenção mais estabelecida, de modo que isso pudesse cumprir as metas definidas obtendo assim uma melhor compreensão a respeito do tema abordado, contribuindo assim para uma melhor aplicabilidade de destes processos neste contexto tão importante para os fármacos que atuam neste segmento.

Density functional theory (DFT) provides a powerful tool for investigating the promotional effect on C2 selectivity of finely tuned catalyst structures, which is currently difficult to control using experimental techniques, such as interatomic distances.

So far, there have been 4 methods to control chirality including the use of chiral auxiliaries, reagents, solvents, and catalysts documented in literature and textbooks. Among them, asymmetric catalysts are normally divided into homogeneous and heterogeneous catalysis. In this report, we present a new type of asymmetric control—asymmetric catalysis via chiral aggregates that would not belong to the above categories. This new strategy is represented by catalytic asymmetric dihydroxylation reaction of olefins in which chiral ligands are aggregated by taking advantage of typical aggregation-induced emission systems containing tetrahydrofuran and H
2
O cosolvents. It was proven that the chiral induction can be enhanced from er of 78:22 to 97:3 simply by changing the ratios of these 2 cosolvents. The formation of chiral aggregates of asymmetric dihydroxylation ligands, (DHQD)

PHAL and (DHQ)

PHAL, has been proven by aggregation-induced emission and a new analytical tool—aggregation-induced polarization established by our laboratory. In the meanwhile, chiral aggregates were found to be formed either by adding NaCl into tetrahydrofuran/H
2
O systems or by increasing concentrations of chiral ligands. The present strategy also showed promising reverse control of enantioselectivity in the Diels–Alder reaction. This work is anticipated to be extended broadly to general catalysis, especially to asymmetric catalysis in the future.

There is a well-known adage in scientific work that all results of scientific research for a thesis or dissertation, whether the aim is to discover or build a new theory, test a theoretical model, test a theory, or formulate a policy brief, must be published. Research for essay writing can also be published, while research for exam purposes is not intended to be published (Bailey, 2004). The publication of the results of our research is one of the ways according to Cumming (2006) and Epstein, Kenway & Boden (2007) so that the findings of our scientific research can be accessed, known, and read widely so that the world knows each other and all scientific activities are connected to each other as a mutually enlightening system. All research must be published it is the iron law of history. The iron law that applies in the world of science has been widely known among academics and scientists, all research results, whatever their form, must be published in scientific journals so that they can be widely disseminated to world readers, or if not, they will only turn into piles of paper reports that become mere waste or perish. The results of scientific work will just be piled up as mere documentation as research reports, without outputs, let alone outcomes, which are proud and have a wide impact.
RANCANG BANGUN SISTEM KONTROL MINIATUR ALAT PEMINDAH MATERIAL PADA PROSES DISTRIBUSI BIJIH NIKEL MENGGUNAKAN PLC

This research aims to make a miniature ore material transfer tool automatically using Omron PLC. The way this tool works is that when the start button is pressed, motor 1 will move the apron containing the ore to be taken to the 3 storage barrels to be filled alternately. In each storage barrel, a proximity sensor is installed to detect the level of ore filling. On the rails that are passed by the apron, there are three limit switches that serve as indicators that the position of the apron is right above the storage barrel, then motor 2 will open the valve on the apron so that the ore on the apron falls into the reservoir. From this research, we have succeeded in obtaining an automatic control system for a miniature material transfer device in the ore distribution process.
El éxito (o lo que queda del fracaso)
Authors: Arrese Igor Blas
Published: May 2023

En tiempos de post postmodernidad, en tiempos en donde las artes vivas se piensan exánimes, autofagocitadas, devastadas, Blas Arrese Igor construye dos materiales que -poniendo el cuerpo en medio de ese barro definitivo en el que se lee el teatro hoy- construye una reflexión poderosísima sobre la práctica escénica sin dejar de lado las emociones. Estas dos obras leen el teatro y sus prácticas, critican los límites autoimpuestos por los saberes académicos (post dramático y otras, varias, repelentes yerbas), construyen teatralidad y -lejos de pelearse con la reflexión- no hacen sino transformarla en acción, en juego, en ilusión escénica. El Fracaso y El éxito son dos materiales que se imponen como una extraordinaria manera de leer el teatro y sus tradiciones, el teatro y sus prácticas contemporáneas.

The aim of this research is to find out the Adaptation of Michael Porter's Differentiation Strategy: Cyberspace as the Main Facility of Startup Business in Post-Pandemic. This type of research is qualitative research. The research process is by collecting data from secondary data sources through observation and research results that have been published in journals that already have indexes, credible census data related to research and mass media reports that have valid credibility. The Competitive Strategies model put forward by Porter is one of the popular strategies to explain how the design of an organization, especially a money-oriented organization, can work well, some of the benefits of working indirectly along with the disadvantages. During the pandemic there was a shift in working methods in various sectors. The face-to-face method is not possible, so it is necessary to use a video teleconference platform. Issues regarding organizational strategy and design can be addressed through the concept of comparative advantage which includes Porter's differentiation strategy. The implementation of this strategy is capable and capable of increasing organizational resilience as adapted by Schoters and Ruang Guru. These companies have even carried out the differentiation method well when implementing differentiating strategy.
