Influence of Copper and Zinc Tailing Powder on the Hydration of Composite Cementitious Materials
Authors: Han Weiwei , Han Fanghui , Zhang Ke
Published: August 2022

Copper and zinc tailing powder (CZTP) is finely ground waste after copper minerals and zinc minerals have been extracted from ores during beneficiation. CZTP has certain potential cementitious properties and can be used in composite cementitious materials. The pore size distribution and hydrate phase assemblage of the hardened samples are investigated using MIP and XRD. SEM is employed to examine the microstructure of the specimens. The chemically bonded water is used to measure the degree of hydration. CZTP lowers the hydration heat evolution rate and the total hydration heat. The hydration heat evolution rate reduces as the w/b ratio rises, whereas the total hydration heat of blended cement paste rises. CZTP diminishes the strength development of the Portland-CZTP system, and the strength decreases as the CZTP level increases. CZTP reduces the critical pore diameters of the Portland-CZTP system with w/b = 0.3 after curing for 3 d and 28 d, while increasing the critical pore diameters of samples with w/b = 0.45 at the same age. CZTP increases the gel micropores of Portland-CZTP. Although CZTP increases the pore volume content of blended cement pastes with w/b = 0.3, the volume of harmful pores decreases. The pore volume content of the Portland-CZTP system decreases as the w/b ratio increases. However, the volume of harmful pores increases with a higher w/b ratio. The main hydration products in the Portland-CZTP system are portlandite, ettringite, and C-S-H. CZTP mainly played the role of filling or acting as a microaggregate in the Portland-CZTP system.

Published: August 2022

The paper deals with the analysis of the rotational stiffness of a semirigid connection created from a system of two stands and a rung. The connection was made from glued laminated timber with metal mechanical dowel-type fasteners. Not only a common combination of bolts and dowels but also fully threaded screws were used for the connection. The aim of the research and its motivation was to replace commonly used fasteners with more modern ones, to shorten and simplify the assembly time, and to improve the load-carrying capacity of this type of connection. Each of these two types of connection was loaded to the level of 60%, 80%, and 100% of the ultimate limit state value. Subsequently, the rotational stiffness was determined for each load level after five loading and unloading cycles. This paper presents the results and comparison of the experimental testing and the numerical modeling. The obtained results were also compared with the assumption according to the currently valid standard.

Background and Objectives: In March 2020, COVID-19 pandemic affected the world. All countries, to limit viral transmission, imposed quarantine. This emergency exerted personal, social, economic, and psychological impact on people. For health systems, was needed to create alternative care pathways. Telemedicine can be helpful to reduce isolation, provide health care services, and monitor virus infections. Italian regions, including Sicily, have activated telemedicine services for management of patients with COVID-19. Objective: The purpose of study is to describe a Sicilian telemedicine model for management of COVID-19 patients, showing results on feasibility, usability and quality of service and patient satisfaction. Materials and Methods: This is a descriptive exploratory study on a telemedicine service for residents in Messina infected by COVID-19. It included monitoring of vital signs and specialist consultations (i.e., doctor, psychologists, social workers, and nutritionist biologists). Results: More than twenty percent (23.8%) of participants used tele-monitoring and tele-counselling services; 14.3% were only telemonitored. Participants judged positively telemedicine service (30% were quiet and 50% were very satisfied), as well as tool (70% were quiet and 10% were very satisfied). Telemonitoring had a low agreement (10% were slightly satisfied and 50% were neutral); tele-counselling had a high rate of satisfaction (40% quiet and 60% were very satisfied). Conclusions: This study showed that telemedicine model for Sicilian population affected by COVID-19 was feasible, easy to use and appreciated by patients. Our promising results allow us to assume that if in Sicily there was a return of the emergency, we would be ready to manage it This system can be the solution to remote management of these patients, to reduce isolation, provide health services, and monitor virus infections. The use of this technology should encourage future research to change the health care system and provides opportunities to ensure health and care for oneself and others.

Published: August 2022

This study presents a biophotocatalytic system as a sustainable technology for the recovery of clean water and renewable energy from wastewater, thereby providing a unique opportunity to drive industrialization and global sustainable development throughputs. Herein, inhouse magnetized photocatalyst (Fe-TiO2) with surface area 62.73 m2/g synthesized via co-precipitation, was hypothesized to hasten an up-flow anaerobic sludge blanket (UASB) reactor for the treatment of local South Africa municipality wastewater with the benefit of high-quality biogas production. A lab scale UASB process with a working volume of 5 L coupled with two UV-lights (T8 blacklight-blue tube, 365 nm, 18 W) was operated batchwise under mesophilic conditions for the period of 30 days with a constant organic load charge of 2.76 kg COD/m3. d. This biophotocatalytic system performance was investigated and compared with and without the Fe-TiO2 charge (2–6 g) with respect to effluent quality, biogas production and CO2 methanation. Using chemical oxygen demand (COD) measured as the degree of degradation of the pollutants, the best efficiency of 93% COD removal was achieved by a 4 g Fe-TiO2 charge at 14 days and pH of 7.13, as compared to zero charge where only 49.6% degradation was achieved. Under the same charge, cumulative biogas and methane content of 1500 mL/g COD.d and 85% were respectively attained as compared with the control with 400 mL/g COD.d and 65% methane content. Also, the energy produced can be used to offset the energy utilized by the UV-light for the wastewater abatement and other limitations of photocatalysis. The BP system was found to be an eco-friendly and cost-effective technology to be explored in water treatment settings.

Published: August 2022

Constructing heterojunction is an attractive strategy for promoting photoelectrochemical (PEC) performance in water splitting and organic pollutant degradation. Herein, a novel porous BiVO4/Boron-doped Diamond (BiVO4/BDD) heterojunction photoanode containing masses of ultra-micro electrodes was successfully fabricated with an n-type BiVO4 film coated on a p-type BDD substrate by magnetron sputtering (MS). The surface structures of BiVO4 could be adjusted by changing the duration of deposition (Td). The morphologies, phase structures, electronic structures, and chemical compositions of the photoanodes were systematically characterized and analyzed. The best PEC activity with the highest current density of 1.8 mA/cm2 at 1.23 VRHE was achieved when Td was 30 min, and the sample showed the highest degradation efficiency towards tetracycline hydrochloride degradation (TCH) as well. The enhanced PEC performance was ascribed to the excellent charge transport efficiency as well as a lower carrier recombination rate, which benefited from the formation of BiVO4/BDD ultra-micro p-n heterojunction photoelectrodes and the porous structures of BiVO4. These novel photoanodes were expected to be employed in the practical PEC applications of energy regeneration and environmental management in the future.

Published: August 2022

Electrochemically activated glassy carbon electrode (AGCE) was fabricated and applied for sensitive and selective detection of sunset yellow (SY). The electroanalysis of SY was investigated by square wave voltammetry (SWV). Owed to the specific oxygen-contained functional groups and the outstanding conductivity of AGCE, the proposed sensor exhibits an enhanced oxidation peak current of SY when compared with non-activated glass carbon electrode (GCE). Under the optimal analytical conditions, the oxidation peak current is linear with SY concentration in the range of 0.005–1.0 μM. The low limit of detection is 0.00167 μM (S/N = 3). This method is applied for the detection of SY in the actual samples. The recovery is between 96.19 and 103.47%, indicating that AGCE is suitable for the determination of SY in beverage sample.

Published: August 2022

A new luminescent hybrid material based on silica aerogel and a boron-containing coordination compound with 8-hydroxyquinoline was created, and its physicochemical and spectral-luminescent characteristics were studied. A simple scheme for the synthesis of a hybrid luminescent material was developed. Simultaneously with the synthesis of the aerogel, the formation of a boron-containing phosphor was carried out using an isopropanol solution of boric acid and 8-hydroxyquinoline. Using in situ luminescent measurements, the mechanisms of the formation of boron-based luminescent complexes in isopropanol and tetrahydrofuran media were established. Both hydrophilic and hydrophobic silica aerogels were tested as matrices for the hybrid material. The formation of a thin layer of a boron-containing coordination luminescent compound on the highly developed surface of the SiO2 aerogel made it possible to strongly stabilize the aerogel structure and noticeably increase the thermal stability of the synthesized hybrid material.

Published: August 2022

Intestinal ischemia/reperfusion (II/R) injury is a common life-threatening complication with high morbidity and mortality. Chebulae Fructus Immaturus, the unripe fruit of Terminalia chebula Retz., also known as “Xiqingguo” or “Tibet Olive” in China, has been widely used in traditional Tibetan medicine throughout history. The phenolic acids’ extract of Chebulae Fructus Immaturus (XQG for short) has exhibited strong antioxidative, anti-inflammation, anti-apoptosis, and antibacterial activities. However, whether XQG can effectively ameliorate II/R injuries remains to be clarified. Our results showed that XQG could effectively alleviate II/R-induced intestinal morphological damage and intestinal barrier injury by decreasing the oxidative stress, inflammatory response, and cell death. Transcriptomic analysis further revealed that the main action mechanism of XQG protecting against II/R injury was involved in activating PPARα and inhibiting the NF-κB-signaling pathway. Our study suggests the potential usage of XQG as a new candidate to alleviate II/R injury.
Curcumin-Based Nanoformulations: A Promising Adjuvant towards Cancer Treatment

Published: August 2022

Throughout the United States, cancer remains the second leading cause of death. Traditional treatments induce significant medical toxic effects and unpleasant adverse reactions, making them inappropriate for long-term use. Consequently, anticancer-drug resistance and relapse are frequent in certain situations. Thus, there is an urgent necessity to find effective antitumor medications that are specific and have few adverse consequences. Curcumin is a polyphenol derivative found in the turmeric plant (Curcuma longa L.), and provides chemopreventive, antitumor, chemo-, and radio-sensitizing properties. In this paper, we summarize the new nano-based formulations of polyphenolic curcumin because of the growing interest in its application against cancers and tumors. According to recent studies, the use of nanoparticles can overcome the hydrophobic nature of curcumin, as well as improving its stability and cellular bioavailability in vitro and in vivo. Several strategies for nanocurcumin production have been developed, each with its own set of advantages and unique features. Because the majority of the curcumin-based nanoformulation evidence is still in the conceptual stage, there are still numerous issues impeding the provision of nanocurcumin as a possible therapeutic option. To support the science, further work is necessary to develop curcumin as a viable anti-cancer adjuvant. In this review, we cover the various curcumin nanoformulations and nanocurcumin implications for therapeutic uses for cancer, as well as the current state of clinical studies and patents. We further address the knowledge gaps and future research orientations required to develop curcumin as a feasible treatment candidate.

This study investigated the ability of the Brazilian Caffeine Expectancy Questionnaire (CaffEQ-BR), full and brief versions, to differentiate genetic profiles regarding the polymorphisms of the CYP1A2 (rs 762551) and ADORA2A (rs 5751876) genes in a cohort of Brazilian athletes. One-hundred and fifty participants were genotyped for CYP1A2 and ADORA2A. After the recruitment and selection phase, 71 (90% male and 10% female, regular caffeine consumers) completed the CaffEQ-BR questionnaires and a self-report online questionnaire concerning sociodemographic data, general health status, and frequency of caffeine consumption. The order of completion of the CaffEQ-BR questionnaires was counterbalanced. The concordance between the full and brief versions of the CaffEQ-BR was analyzed using the intraclass correlation coefficient (ICC). To determine the discriminatory capacity of the questionnaires for genotype, the receiver operating characteristic (ROC) curve was applied for sensitivity and specificity (significance level of 5%). Mean caffeine intake was 244 ± 161 mg·day−1. The frequency of AA genotypes for CYP1A2 was 47.9% (n = 34) and 52.1% (n = 37) for C-allele carriers (AC and CC). The frequencies of TT genotypes for ADORA2A were 22.7% (n = 15) and 77.3% (n = 51) for C-allele carriers (TC and CC). All CaffEQ-BR factors, for the full and brief versions, were ICCs > 0.75, except for factor 6 (anxiety/negative effects; ICC = 0.60), and presented ROC curve values from 0.464 to 0.624 and 0.443 to 0.575 for CYP1A2 and ADORA2A. Overall, the CaffEQ-BR (full and brief versions) did not show discriminatory capacity for CYP1A2 and ADORA2A gene polymorphisms. In conclusion, the CaffEQ-BR was not able to differentiate genotypes for the CYP1A2 or ADORA2A genes in this group of Brazilian athletes.
Omega-3 Fatty Acids for the Management of Osteoarthritis: A Narrative Review
Authors: Cordingley Dean M. , Cornish Stephen M.
Published: August 2022

Osteoarthritis (OA) is a disease which results in degeneration of cartilage within joints and affects approximately 13.6% of adults over 20 years of age in Canada and the United States of America. OA is characterized by a state of low-grade inflammation which leads to a greater state of cellular catabolism disrupting the homeostasis of cartilage synthesis and degradation. Omega-3 polyunsaturated fatty acids (PUFAs) have been postulated as a potential therapeutic treatment option for individuals with OA. Omega-3 PUFAs are recognized for their anti-inflammatory properties, which could be beneficial in the context of OA to moderate pro-inflammatory markers and cartilage loss. The purpose of this narrative review is to outline recent pre-clinical and clinical evidence for the use of omega-3 in the management of OA.

Published: August 2022

The identification of optimal drug candidates is very important in drug discovery. Researchers in biology and computational sciences have sought to use machine learning (ML) to efficiently predict drug–target interactions (DTIs). In recent years, according to the emerging usefulness of pretrained models in natural language process (NLPs), pretrained models are being developed for chemical compounds and target proteins. This study sought to improve DTI predictive models using a Bidirectional Encoder Representations from the Transformers (BERT)-pretrained model, ChemBERTa, for chemical compounds. Pretraining features the use of a simplified molecular-input line-entry system (SMILES). We also employ the pretrained ProBERT for target proteins (pretraining employed the amino acid sequences). The BIOSNAP, DAVIS, and BindingDB databases (DBs) were used (alone or together) for learning. The final model, taught by both ChemBERTa and ProtBert and the integrated DBs, afforded the best DTI predictive performance to date based on the receiver operating characteristic area under the curve (AUC) and precision-recall-AUC values compared with previous models. The performance of the final model was verified using a specific case study on 13 pairs of subtrates and the metabolic enzyme cytochrome P450 (CYP). The final model afforded excellent DTI prediction. As the real-world interactions between drugs and target proteins are expected to exhibit specific patterns, pretraining with ChemBERTa and ProtBert could teach such patterns. Learning the patterns of such interactions would enhance DTI accuracy if learning employs large, well-balanced datasets that cover all relationships between drugs and target proteins.

Published: August 2022

Quinic acid (QA) and its ester conjugates have been subjected to in-depth scientific investigations for their antioxidant properties. In this study, molecularly imprinted polymers (MIPs) were used for selective extraction of quinic acid (QA) from coffee bean extract. Computational modelling was performed to optimize the process of MIP preparation. Three different functional monomers (allylamine, methacrylic acid (MAA) and 4-vinylpyridine (4-VP)) were tested for imprinting. The ratio of each monomer to template chosen was based on the optimum ratio obtained from computational studies. Equilibrium rebinding studies were conducted and MIP C, which was prepared using 4-VP as functional monomer with template to monomer ratio of 1:5, showed better binding performance than the other prepared MIPs. Accordingly, MIP C was chosen to be applied for selective separation of QA using solid-phase extraction. The selectivity of MIP C towards QA was tested versus its analogues found in coffee (caffeic acid and chlorogenic acid). Molecularly imprinted solid-phase extraction (MISPE) using MIP C as sorbent was then applied for selective extraction of QA from aqueous coffee extract. The applied MISPE was able to retrieve 81.918 ± 3.027% of QA with a significant reduction in the amount of other components in the extract.

Published: August 2022

Work engagement, work efficacy and performance are key concepts in today’s human resources field, impacting both personal and organisational levels. However, not many studies investigate them in a core professional area: pre-university teachers. After measuring the work engagement, work efficacy and work performance variables of teachers, we identified the differences in teachers’ work engagement, work efficacy and work performance according to their seniority in education and the position of the high school in the top national rankings. Our paper’s focus is on exploring the relationship between work engagement and work performance among pre-university teachers from Romanian high schools. This relationship is analysed both directly and indirectly by including work efficacy as a mediating factor. A sample of 817 Romanian high school teachers participated in this study (questionnaire applied in April 2021). The results can lead to a better understanding of human resources behaviour, and, on this basis, to the formulating of human resource policies in the educational field.

Published: August 2022

Corporate sustainability is one of the most challenging issues in superior organizations, and is always one of the main concerns of top managers. The importance of quality management in organizations—especially as total quality management—is considered to be one of the most important indicators of sustainability. We cannot achieve sustainability and its important sub-parameters—including economic and social sustainability—by merely employing the value of knowledge creation and knowledge sharing, without also focusing on customers, leadership, and process management. We designed appropriate questionnaires to test this premise, and then distributed and collected them from various reputable pharmaceutical companies in Turkey. We recorded the opinions of managers, supervisors, and deputies of different departments at various organizational levels. To analyze the data, SPSS software—one of the well-known applications in this field—was used. The new regular economy introduces new requirements for newly built public universities or pharmaceutical companies; therefore, their transformation and development are imminent. For example, colleges should comply with the new requirements of economic and social transformation for higher education, innovate their talent training models, and cultivate higher ideological standards and morality while instilling strong practical ability in their graduates to serve society. The results of this study not only illustrate the positive effects of total quality management on firms’ sustainability, but also validate knowledge management and its sub-variables, including knowledge creation and sharing. In addition, they confirm the mediating role of sub-variables, including knowledge creation and knowledge sharing in companies, influencing the effects of total quality management on the sustainability of companies.

Published: August 2022

Background: mpMRI assesses prostate lesions through their PI-RADS score. The primary goal of this prospective study was to demonstrate the correlation of PI-RADS v2 score and the volume of a lesion with the presence and clinical significance of prostate cancer (PCa). The secondary goal was to determine the extent of additionally PCa in inconspicuous areas. Methods: All 157 patients underwent a perineal MRI/TRUS-fusion prostate biopsy. Targeted biopsies as well as a systematic biopsy were performed. The presence of PCa in the probes was specified by the ISUP grading system. Results: In total, 258 lesions were biopsied. Of the PI-RADS 3 lesions, 24% were neoplastic. This was also true for 36.9% of the PI-RADS 4 lesions and for 59.5% of the PI-RADS 5 lesions. Correlation between ISUP grades and lesion volume was significant (p < 0.01). In the non-suspicious mpMRI areas carcinoma was revealed in 19.7% of the patients. Conclusions: The study shows that the PI-RADS v2 score and the lesion volume correlate with the presence and clinical significance of PCa. However, there are two major points to consider: First, there is a high number of false positive findings. Second, inconspicuous mpMRI areas revealed PCa.

Methanolic Extract From Cocoa Bean (Theobroma Cacao L.) As A Potential Active Ingredient In Mouthwash
Authors: Mardiah Ainun , Cut Aja Nuraskin
Published: August 2022

Dental plaque is a soft deposit firmly attached to the surface of teeth, formed from a mixture of saliva; such as mucin, remnants of oral tissue cells, leukocytes, lymphocytes with food debris, and bacteria resulting in the initial occurrence of tooth decay due to reduced pH. Unfortunately, currently available antiseptics-based mouthwash, used to prevent dental plaque formation, is thought to have a carcinogenic effect. Therefore, an alternative plaque was proposed using herbal antibacterial agents. Cocoa beans have anti-bacterial properties and are known to have active anti-bacterial agents, these substances are flavonoids, phenolics, alkaloids, terpenoids, saponins, and tannins. Herein, we aimed to determine the phytochemical content of methanol extract from cocoa bean (Theobroma cacao L.) and its antibacterial activities against Streptococcus mutans and subsequently studied its potential as a mouthwash active ingredient. Macerated methanolic extract of cocoa bean was investigated against clinical isolates of S. mutans. Qualitative phytochemical tests were further performed to observe the presence of flavonoids, phenolics, alkaloids, terpenoids, saponins, and tannins. The results showed that the growth of S. mutans colonies at a concentration of 1, 2, and 3% were 431×104, 142×104, and 59.5×104 CFU/mL, respectively. Addition of the extract at all concentrations (1—3%) did not affect the color, aroma, taste, and clarity of the mouthwash. An acute toxicity test on mice model confirmed that the cocoa bean-based mouthwash was safe.

O Cortiço : o romancista social em Aluísio de Azevedo
Authors: Tamura Sílvio Takeshi
Published: August 2022

Este trabalho desvela-se nalgumas reflexões sobre o romance O Cortiço, do escritor maranhense Aluísio Azevedo. Fora publicado originalmente ao cabo do século XIX, mais precisamente, em 1890. Aportados em diversos pensadores, pretende-se engendrar algumas considerações sobre o caráter sociológico deste literato, impresso nas tramas desta obra. Nesta pesquisa, parte-se da dissecção de que este autor utilizava-se de suas escritas para tecer duras críticas à sociedade. Expunha ideias, repreendia condutas e repugnava o conservadorismo da época. Recebeu influências de diversos outros intelectuais, entre eles: Émile Zolá, na França; Eça de Queirós, em Portugal; Karl Marx, na Alemanha; e Artur Azevedo, no Brasil. Este último, renomado teatrólogo, escritor e jornalista brasileiro, era seu irmão mais velho, e de maneira decisiva, incentivou-o a dedicar-se ao mundo das Artes, Letras e Teatro. Militante abolicionista, Aluísio Azevedo condenava a exploração do homem pelo homem, o escravismo e outras adversidades. Aclamado pela crítica, O Cortiço, deveras, apresenta-se como sua obra-prima – expressa nitidamente o Naturalismo – corrente filosófica iniciada na Europa, e a posteriori, transladada para o Brasil pelas mãos deste romancista. Singularizava a observação legítima dos fatos, assentados no Positivismo, Darwinismo e Determinismo. O Cortiço retrata vícios, contrariedades, problemas sociais e atrocidades imersos no final dos Oitocentos. Apesar de ficção, interpreta a sociedade por intermédio da Literatura.

Espólios violentos: a transmissão transgeracional da ditadura militar no romance brasileiro do século XXI
Authors: Gill da Cruz Lua
Published: August 2022

Há “giro geracional”, nos termos de Leonor Arfuch (2018), em curso, em relação à produção artística dedicada ao tema da ditadura militar no Brasil: agora, deslocados temporalmente, autores e autoras de uma segunda geração do evento, herdeiros dos traumas do(s) outro(s), tomam de assalto a palavra sobre o passado brasileiro, seja ela familiar ou não, e reabrem o que é aparentemente (des)conhecido. Neste artigo, se analisará, especialmente, as narrativas que questionam as formas de transmissão dos sentidos do passado ditatorial brasileiro por aqueles que não o viveram diretamente, a partir dos livros O amor dos homens avulsos (2016), de Victor Heringer e O corpo interminável (2019), de Claudia Lage, observando, em especial, como os textos discutem as formas de transmissão da violência e do medo, parte do ambiente familiar e nacional dos personagens, transmitidos (direta ou indiretamente) ao longo do tempo por aqueles que perpetraram ou colaboraram com o regime ditatorial. Buscaremos atentar então para os restos dessas narrativas não integradas de violência e de legados ainda mais escondidos e negados, observando de que forma são recuperadas pela geração seguinte, como e a partir de que meios sobrevivem e são transmitidas, de que maneira questionam as formas de responsabilização, bem como de que escapam à e se mantém na obscuridade, tantos anos depois.
Estéticas insurgentes: produções artísticas no Brasil contemporâneio
Authors: Guimarães Andrade Tanure Milena
Published: August 2022

Em tempos de crise, o campo cultural tem se constituído espaço de resistência e insurgência, não se abstendo da sua força estética e política. Diante disso, o presente artigo pensa a produção contemporânea a partir das ideias de ocupação analisando usos outros dos espaços sobretudo urbano e artístico. São colocadas em cena produções artísticas (TERÇA-NADA, 2021), como poemas e um curta, que, surgindo no tempo presente, provocam o nosso tempo e vão se propondo a ressemantizar a cidade que se apresenta ambígua, enigmática, labiríntica, fragmentada. A partir delas temos a materialização do fim das metanarrativas (LYOTARD, 1993) e a escrita dos ruídos, dos restos, como estéticas insurgentes (PÁL PELBART, 2000; DIDI-HUBERMAN, 2011; AGAMBEN, 2008).
