Elastic wave propagation in cubic non-centrosymmetric and chiral architectured materials: insights from strain gradient elasticity
Authors: Rosi Giuseppe
Published: March 2024

The study of elastic wave propagation is a fundamental tool in different fields, from Non-destructive Damage Evaluation (NDE) to ultrasonic imaging. Usually NDE and characterisation techniques rely on inversion methods based on homogenised theories, that are valid only when the wavelength of the perturbation is considerably larger than the characteristic size of the heterogeneities of the materials. When the wavelength approaches this characteristic size, an upscaling occurs and mesoscopic effects can be transferred to the macro-scale. In this case, classic models used in the aforementioned inversion procedures can fail to predict the correct response [1] and they need to be improved [2].
In this work, we address those architectures for which the unit cell does not have any centre of inversion (non-centrosymmetric) nor symmetry plane (chiral). It will be shown that unconventional effects, in terms of dispersion and polarisation, can be observed even for large wavelengths. We will also prove that for describing these materials using an equivalent homogeneous continuum, the use of an enriched or generalized theory, such as strain gradient elasticity, is mandatory. Moreover, the analysis of the generalised acoustic (or Christoffel) tensor defined in this framework can give a useful insight on the dynamic features of the architectured material. Among others, the example of the gyroid unit cell will be detailed.

O cobre é um metal que pode se tornar tóxico para o sorgo quando presente em altas concentrações no solo. A utilização de rizobactérias promotoras do crescimento de planta pode ser uma alternativa para o desenvolvimento do sorgo [Sorghum bicolor (L.) Moench] em solo contaminado com cobre. Objetivou-se determinar o efeito da inoculação de Azospirillum brasilense no desenvolvimento e teores de cobre do sorgo cultivado em solo contaminado com Cu, possibilitando o reaproveitamento dessas áreas. O delineamento experimental foi de blocos casualizados em arranjo fatorial (9 × 2), sendo avaliadas nove doses de cobre [(0: teor natural do solo), 30, 60, 90, 120, 150, 180, 240 e 300 mg de cobre kg-1 de solo] com e sem inoculação de Azospirillum brasilense, com seis repetições. No tratamento sem inoculação foi realizada aplicação de nitrogênio na dose de 200 kg-1 ha. Foram avaliados a altura de planta, o diâmetro do colo, a massa seca da parte aérea (MSPA), o volume, o comprimento e a massa seca radicular (MSR), o índice relativo de clorofila a e b e os teores de cobre na MSPA e MSR. A inoculação com Azospirillum brasilense possibilita maior índice de clorofila A e B e desenvolvimento da parte aérea do sorgo, reduzindo o teor de cobre na parte aérea, possibilitando o reaproveitamento de solo contendo 52,5% de argila, contaminado com até 300 mg de cobre kg-1 de solo. A inoculação com Azospirillum brasilense aumenta a área superficial específica de raízes de sorgo em comparação a plantas não inoculadas cultivadas somente com adubação nitrogenada em solo contaminado com cobre.

Published: March 2024

Arsenic poisoning in groundwater is the most common environmental pollutant, which is leading to serious pollution worldwide. Chronic arsenic exposure from drinking water to humans causes major public health-related issues. The present study was conducted to investigate the antidote effects of Foeniculum vulgare (Fennel) against arsenic-induced hepatotoxicity and testicular toxicity in Charles Foster rats. In the present study, twenty-four male Charles Foster rats (120±5gm) were divided into four Groups (n=6), where control Group-I received a normal diet and water; Group - II and Group - III received sodium arsenite (8 mg per kg body weight per day) for 90 days. Group III was left with a normal diet and water for the next 60 days for auto-recovery. The group IV rats were administered Foeniculum vulgare (Funnel) hydroxyl ethanolic seed extract at a dose of 150 mg per kg body weight for 60 days in a 90-day pre-treated sodium arsenite group (8 mg per kg body weight). After complete dose duration, all the treated animals were sacrificed the same day for haematological, biochemical, hormonal, and histopathological studies. In the arsenic treated rats, there were significant (p<0.001) changes in serum levels of SGPT, SGOT, urea, uric acid and creatinine as well as in haematological parameters. And there was also decease in the sperm count and sperm motility, accompanied by an increased incidence of sperm abnormalities and hormonal imbalances leading to infertility. In contrast, after the administration of F. vulgare seeds hydroxy-ethanolic extract to arsenic-treated rats, significant (p<0.001) improvements were observed in hepatic and renal parameters as well as haematological parameters. In the arsenic-intoxicant rat, after administration of F. vulgare seeds hydroxyl ethanolic extract, there was a significant (p<001) reduction in the arsenic concentration in blood, liver, and kidney tissues as well as serum LPO. The histopathological study also showed the F. vulgare seeds hydroxy-ethanolic extract significantly restored the cellular integrity of testicular cells, leading to their normal functioning against arsenic-induced toxicity.

Authors: Sousa Marcus Vinicius Carvalho de , Acrani Simone , Vicentine Karina Ferrazzoli Devienne
Published: March 2024

The red yeast rice has been used in therapy for hypercholesterolemia, however data on the phytochemical constitution and other biological properties of this product are scarce in the scientific literature. This objective work evaluates the antioxidant capacity and phytochemical constitution of a commercial phytotherapic and extracts obtained from red yeast rice. The results demonstrated that both the commercial phytotherapic (EMFC), and aqueous (EA), hydroalcoholic (EHA) and ethanolic (EE) exctract presented antioxidant effects, and showed a direct relationship with the phenolic content. Among the extracts evaluated, EE has a higher amount of flavonols/flavones, while extract EA has a higher content of flavonones. The different methods used in the preparation of phytotherapics promote variations in the phytochemical constitution, which may compromise the efficacy and safety of such products. Given this, it is essential that phytotherapic and nutraceuticals are subjected to phytochemical constituents quantification processes in order to guarantee the therapeutic benefits of these natural products on cardiovascular diseases and those associated with oxidative stress.

Coinfections by SARS-CoV-2 with other microorganisms, such as bacteria, viruses and fungi, is a determining factor that must be considered. Because the early detection of these coinfections can directly interfere with the length of hospitalization and, consequently, mortality. This study aimed to identify the epidemiological profile of patients and coinfections associated with COVID-19 carriers in an adult Intensive Care Unit (ICU) of a hospital in the interior of the Amazon. This is a retrospective, descriptive and documentary study, with a quantitative approach. The data sample was obtained from the Hospital Infection Control Commission (E-CCIH) registration system. 95 medical records of patients with COVID-19 associated with coinfections were analyzed. The prevalence of females was 62.1% and the average age was 58 years, 82.1% were brown and the highest prevalence for high school was 32.6%. Related to the site of infection, the study revealed that Ventilator-Associated Pneumonia (VAP) was the most prevalent condition with 53.7% of cases. Regarding the discharges, 60% were due to death. Coinfections associated with COVID-19 reveal a poor prognosis, worsening in the presence of respiratory system comorbidities.

Published: March 2024

Since tobacco use has been linked to COPD for more than 50 years, this population has served as the foundation for almost all of our knowledge regarding the clinical, physiological, pathological, and radiological aspects of the disease as well as the rates of lung function loss and the effectiveness of various treatments. We stated in 1990 that 25 to 45% of COPD cases among never smokers. According to the 2017 Global Burden of Disease report, smoking is only responsible for 35% of the burden of COPD worldwide, with the majority of cases occurring in high-income nations. Most of the world's remaining 65% of nonsmokers with COPD live in low- and middle-income nations. Other non-smoking risk factors for COPD include exposure to biomass smoke while cooking in poorly ventilated homes, high ambient air pollution levels, occupational exposures to dust and gases, ambient ozone exposure, poverty, recurrent respiratory tract infections in childhood, poorly controlled chronic persistent asthma, and prior tubercular lung disease.

Worldwide, non-tobacco-related risk factors, which vary by geographic region, are to blame for around half of all instances of COPD. Inflammation, oxidative stress, airway remodelling, and accelerated lung ageing are potential factors for the development of COPD in never-smokers. Never-smokers with COPD had less severe chronic respiratory symptoms, little to no emphysema, less airflow limitation, and fewer comorbidities than smokers who acquire COPD; however, exacerbations can still happen often. More research- including epidemiological, translational, clinical, and implementation studies- is required to fill in knowledge gaps and promote viable solutions to lessen the burden of COPD in never-smokers. Clinical history and spirometry can be used to diagnose Chronic Obstructive Pulmonary Disease (COPD), but identifying its risk factors is time-consuming and crucial because doing so can stop the disease's progression. Contrary to popular belief, smoking cigarettes is only one of the numerous risk factors for COPD. We have examined the etiology of nonsmoker COPD through this review in an effort to identify the causative risk factor and reduce the disease's morbidity and mortality.

Sperimentazioni teatrali nell’ambiente virtuale: le creazioni digitali di Giacomo Lilliù/Collettivo Ønar
Authors: Giuliani Francesca
Published: March 2024

A partire dalle sperimentazioni online degli artisti e delle artiste delle performing arts durante il biennio pandemico (Gemini, Brilli, Giuliani, 2020; Monteverdi, 2023) si osserva oggi il consolidarsi dell’esperienza di alcuni degli «emergency experimenters» (Brilli, Gemini, Giuliani, 2022) che continuano a mettere alla prova differenti gradienti di liveness teatrale (Gemini, Brilli, 2021) per attivare nuove «dinamiche di connessione e coinvolgimento del pubblico» (Patti, 2021). Questi progetti innovativi, che si muovono tra performance, piattaforme e pubblici connessi, interrogano la natura dei dispositivi digitali per ricontestualizzare dinamiche e pratiche teatrali, coreografiche e performative negli ambienti virtuali. Assistendo ora, superata la fase dell’emergenza, a una restaurazione sia a livello delle programmazioni dei teatri che dei sostegni alla produzione, sembra necessario provare a storicizzare questo fenomeno tenendo traccia delle digital performance (Dixon, 2007) online e degli OTONI  – Oggetti Teatrali Online (Non Identificati). Per questo motivo il contributo esplora l’evolversi della ricerca teatrale nel contesto digitale dell’artista Giacomo Lilliù/Collettivo Ønar, osservandola a partire dal processo di mediatizzazione del teatro (Del Gaudio, 2021; Brilli, Gemini, 2022).

Estadística descriptiva en el nivel secundario y superior: revisión bibliográfica entre 2010 y 2020
Authors: Mostto Florencia , Parra Veronica
Published: March 2024

Introducción: la enseñanza de la estadística suele quedar relegada a pesar de su presencia en los programas oficiales, y así genera un fenómeno didáctico que conduce al desarrollo de investigaciones en el área e, incluso, la necesidad de una didáctica específica. Metodología: este trabajo presenta los resultados de una revisión bibliográfica y categorización inductiva de 70 artículos de investigación referidos a la educación estadística en el nivel secundario y superior. Esta selección se realizó de forma intencionada considerando el idioma español y publicados en revistas indexadas y actas de congresos reconocidos durante el periodo 2010-2020. Resultados y discusión: el análisis inductivo permitió generar las siguientes categorías: lugar y año de la investigación, nivel escolar, marco teórico, foco, problema, objetivos, metodología y conclusiones/resultados más relevantes, con sus correspondientes subcategorías. Además de la generación de categorías y subcategorías, este análisis posibilitó concluir que uno de los problemas de investigación explicitados con mayor frecuencia es la enseñanza de la estadística sin sentido, caracterizada por privilegiar un conocimiento técnico; que el foco preponderante es el análisis del conocimiento de los estudiantes; que el marco teórico más frecuente es el enfoque ontosemiótico de la cognición e instrucción matemática; que la metodología más usada es la aplicación de cuestionarios. Conclusiones: se concluye la preponderancia otorgada al “estudiante” como centro de este problema, lo que remite a reflexionar sobre la necesidad de considerar (y abordar) el fenómeno desde todos los componentes de la tríada didáctica: estudiantes-profesores-saber.

Diets composed of whole flint corn grain (WCG) without any roughage source are often used in South American countries. The primary source of protein in theses diets is soybean meal. We hypothesized that the combination of different protein sources improves ruminal fermentation and nutrient digestibility. This study was carried out to assess the impacts of replacing 50% of the soybean meal by other protein sources on voluntary dry matter intake (DMI), digestibility, efficiency of N utilization, efficiency of grain use, metabolic characteristics, and ingestive behavior of Nellore cattle fed WCG diets. Five rumen-cannulated Nellore Bulls (average BW = 651.6 ± 31.83 kg) were used in a 5 x 5 Latin square design, randomly assigned to five diets consisting of 85% of WCG and 15% of pellet supplement with combination of different protein sources: SM - pellet supplement with soybean meal only; CM - soybean meal and cottonseed meal; SFM - soybean meal and sunflower meal; DDG - soybean meal and DDG; DDGS - soybean meal and DDGS. The replacement of 50% of soybean meal by DDG increased (P<0.05) DMI and organic matter intake (OMI), both DMI and OMI were lower with CM. Digestibility, ruminal pH (mean = 5.7), efficiency of N utilization, and diurnal ingestive behavior were not affected (P>0.05) by protein sources. Protein sources also did not affect the grain-use efficiency (P>0.05), with an average value of 96.6% and only 3.4% of the corn grains recovered in the feces. The concentration of GGT enzyme was greatest (P<0.05) for CM and DDGS. The inclusion of DDG increased the DMI but did not improve the nutrients’ digestibility or N metabolism. The results suggest that 50% of the [1]soybean meal can be replaced by sunflower meal, DDG, and DDGS without affecting the nutritional and metabolic parameters of Nellore cattle fed whole flint corn grain diets, providing opportunities for reducing costs in feedlot systems.

Published: March 2024

As bactérias solubilizadoras de fosfato (BSF) possuem capacidade para liberar o fósforo (P) que está adsorvido no solo, convertendo fosfato insolúvel em formas solúveis, tornando-o disponível para a absorção pelas plantas. Estas bactérias podem ser encontradas naturalmente no ambiente, tendo o solo como maior reservatório. Além de serem consideradas benéficas e seguras, as BSF representam uma alternativa viável para uso agrícola, pois podem ser multiplicadas e devolvidas à rizosfera (inoculantes, bioestimulantes, biofertilizantes, biopesticidas) para estimular o crescimento das plantas por meio de mecanismos diretos e/ou indiretos. No entanto, encontrar isolados eficientes e adaptados às diversas culturas e sistemas de cultivo permanece um grande desafio. Esta pesquisa teve por objetivo prospectar BSF a partir do solo de diferentes áreas e selecionar, por meio de ensaios in vitro, cepas eficientes e com maior potencial para uso agrícola, bem como, avaliar os efeitos da inoculação em sementes de arroz de terras altas. A partir de amostras de solo coletadas em área conservada do bioma Amazônia, área agrícola produtiva do bioma Cerrado e área degradada com subsolo exposto do bioma Cerrado, foram obtidos 32 isolados solubilizadores. Destes, três foram selecionados pela capacidade de solubilização in vitro para fosfato de cálcio e/ou fosfato de ferro, e com início de solubilização precoce. Identificados como Pantoea sp., Enterobacter sp. e Klebsiella sp., os mesmos não apresentaram danos à sanidade das sementes de arroz, ou à germinação e emergência das plântulas, além de promoverem aumento do comprimento das raízes.

Published: March 2024

Neste estudo buscou-se apresentar uma análise literária de contos da tradição oral, provenientes do acervo literário dos contadores tradicionais de histórias da cidade de Tapiramutá, Chapada Diamantina, Bahia, para tanto, parte-se das reflexões epistemológicas de Aristóteles (1992), Rosenfeld (1994) e Staiger (1977), sobre o entrelaçamento e diálogo entre os gêneros épico/narrativo, lírico e dramático - a intergenericidade poética. Evidenciou-se por meio das análises a quatro contos da tradição oral, a presença do enlaçamento, da interpenetração entre os gêneros líricos, épico/narrativo e dramático, assinalando assim para o fato dos gêneros literários aparecerem misturados, mesclados. Bem como, percebeu-se que por meio desse imbricado diálogo entre os gêneros são revelados traços da cultura, da história, dos contextos geográficos, sociais e políticos tanto dos sujeitos enunciativos (contadores tradicionais) quanto da sua coletividade.
Extrapulmonary, Chronic Septic Arthritis From Mycobacterium tuberculosis in the Ankle and Subtalar Joints
Authors: Compton Tyson , Ferguson Nicholas Andrew , Certain Laura , Nixon Devon
Published: March 2024

In the United States, rates of Mycobacterium tuberculosis infection have been declining for decades. Osteoarticular tuberculosis of the ankle is rarely observed. We present the case of a 65-year-old man who immigrated to the United States from India 24 years before the onset of symptoms. The patient initially reported atraumatic swelling and pain of the left ankle and foot and was treated for venous insufficiency. Later, the patient was referred to a nonsurgical orthopaedic clinic for additional workup and was found to have elevated inflammatory markers. MRI showed septic arthritis and osteomyelitis of the talus, distal tibia, and calcaneus. Joint aspiration revealed elevated white blood cell counts with predominately PMNs. The patient was then referred to an orthopaedic foot and ankle surgeon and underwent extensive irrigation and débridement. The patient was discharged on empiric antibiotics. Culture results from the original joint aspirate returned 14 days after surgery as positive for acid-fast bacillus, later identified as M tuberculosis by sequencing. Empiric antibiotics were discontinued, and the patient was started on appropriate antituberculotic therapy.

This research used quasi experimental design method with nonequivalent control group design. There were 31 students who became research samples in class VII B as the experimental group, and 31 other students in class VII C as the control group. Data were collected through multiple choice tests consisting of pretest and posttest. The data analysis technique used is the normality test with the shapiro wilk formula and the hypothesis test using the mann whitney u test. Based on the results of data analysis, it was found that class VII B as the experimental group obtained a score of 77.25, while class VII C as the control group amounted to 43.54. There is a significant inequality in both data. The normality test results on the pretest and posttest data of the experimental group and control group were not normally distributed with a value of 0.000. Based on hypothesis testing on the mann-whitney u test of 0.000 <0.05, which means Ha is accepted and Ho is rejected. In addition, the calculation of the effect size test resulted in a value of 0.41 which shows problem-based learning has a positive impact on student learning outcomes compared to conventional social studies learning with a medium category

Azərbaycan xarici siyasətininstrategiyasında daxili multikulturalizm amili
Authors: MAGOMEDOVA Aida
Published: March 2024

Tədqiqatın məqsədi. Multikulturalizm mədəni plüralizmi nəzərdə tutan və təşviq edən siyasətdir. Bu, insanlara etnik, irqi və dini fərqlərindən asılı olmayaraq istənilən ölkənin bütün əhalisinin hüquqlarına hörmətlə bağlıdır. Multikultural cəmiyyətdə ölkənin bütün vətəndaşları öz mədəniyyətinin, dilinin, adətənənələrinin, etnik və dini dəyərlərinin inkişafında bərabər hüquqlara malikdirlər. Belə bir cəmiyyətdə məktəblər açılır, dillərində qəzet və jurnallar nəşr olunur. Bundan əlavə, multikulturalizm prinsipləri təkcə siyasi elita tərəfindən deyil, xalqın yüksək vəzifələr tutmayan digər nümayəndələri tərəfindən də geniş şəkildə dəstəklənir. Tədqiqatın metodu. Multikulturalizmin nəzəri əsasını liberalizm, əsas da onun azadlıq, bərəbərlik və qardaşlıq kimi dəyərləri təşkil edir. Bundan əlavə, multikultural cəmiyyət təkcə sosial ədalətsizliyə deyil, həm də irqçiliyə bağlı ədalətsizliyə qalib gəlmənin mümkün olduğu liberal cəmiyyətdir. Bununla belə, liberalizmdən fərqli olaraq, multikulturalizm ayrı-ayrı fərdlərin deyil, etnik və mədəni qrupların hüquqları ilə məşğul olur. Tədqiqatın nəticələri. Multikulturalizm öz mahiyyətinə görə tolerantlıq siyasətinə çox yaxın siyasətdir. Tolerant cəmiyyətin ən mühüm xüsusiyyəti müxtəlif mədəniyyətlərin paralel mövcudluğudur. Tolerant cəmiyyətdə multikulturalizm mədəniyyətlərin qarşılıqlı zənginləşməsinə töhfə verir və bu, insanların daha da mədəni birləşməsi üçün bir mədəniyyətin digər mədəniyyətə nüfuz etmə prosesi ilə bağlıdır.

Introduction: Obstructive sleep apnea syndrome (OSAS) is characterized by intermittent partial or complete obstruction of the airways during sleep and is called OSAS syndrome when associated with day/night symptoms and/or comorbidities, such as systemic arterial hypertension or diabetes mellitus. The prevalence reaches 32% in the general population, varies between 1% and 20% when associated with COPD (overlap syndrome), and is described as above 60% in populations with COPD and obesity. Orthognathic surgery (OC) can correct deformities of the maxillary and mandibular bones in OSAS. Objective: It was to develop the main approaches and clinical results of orthognathic surgery for the treatment of obstructive sleep apnea syndrome through a systematic review. Methods: The PRISMA Platform systematic review rules were followed. The search was carried out from November 2023 to February 2024 in the Scopus, PubMed, Science Direct, Scielo, and Google Scholar databases. The quality of the studies was based on the GRADE instrument and the risk of bias was analyzed according to the Cochrane instrument. Results and Conclusion: 146 articles were found, 58 articles were evaluated and 26 were included in this systematic review. Considering the Cochrane tool for risk of bias, the global assessment resulted in 32 studies with a high risk of bias and 22 studies that did not meet GRADE. Most studies showed homogeneity in their results, with X2 =65.8%>50%. Maxillomandibular advancement surgery is a successful treatment for obstructive sleep apnea, but there are still concerns about cosmetic results due to the major advances involved. Bimaxillary advancement osteotomy significantly increases oropharyngeal volume and contracted superficial areas, which remain stable between 6 months and 1 year postoperatively.
