Published: November 2021

The present work reports the synthesis of a stable aqueous magnetic fluid (AMF) by dispersing double-surfactant-coated Fe3O4 magnetic nanoparticles (MNPs) in water using a facile ambient scalable wet chemical route. MNPs do not disperse well in water, resulting in low stability. This was improved by dispersing double-surfactant (oleic acid and sodium oleate)-coated MNPs in water, where cross-linking between the surfactants improves the stability of the AMFs. The stability was probed by rheological measurements and all the AMF samples showed a good long-term stability and stability against a gradient magnetic field. Further, the microwave spin resonance behavior of AMFs was studied in detail by corroborating the experimental results obtained from the ferromagnetic resonance (FMR) technique to theoretical predictions by appropriate fittings. A broad spectrum was perceived for AMFs which indicates strong ferromagnetic characteristics. The resonance field shifted to higher magnetic field values with the decrease in particle size as larger-size MNPs magnetize and demagnetize more easily since their magnetic spins can align in the field direction more definitely. The FMR spectra was fitted to obtain various spin resonance parameters. The asymmetric shapes of the FMR spectra were observed with a decrease in particle sizes, which indicates an increase in relaxation time. The relaxation time increased with a decrease in particle sizes (sample A to D) from 37.2779 ps to 42.8301 ps. Further, a detailed investigation of the structural, morphological, and dc magnetic properties of the AMF samples was performed. Room temperature dc magnetic measurements confirmed the superparamagnetic (SPM) characteristics of the AMF and the M-H plot for each sample was fitted with a Langevin function to obtain the domain magnetization, permeability, and hydrodynamic diameter of the MNPs. The saturation magnetization and coercivity of the AMF samples increased with the increase in dispersed MNPs’ size of the samples. The improvement in the stability and magnetic characteristics makes AMFs suitable candidates for various biomedical applications such as drug delivery, magnetic fluid hyperthermia, and biomedicines.

Published: November 2021

Microwave drying of suspensions of lignocellulosic fibers has the potential to produce porous foam materials that can replace materials such as expanded polystyrene, but the design and control of this drying method are not well understood. The main objective of this study was to develop a microwave drying model capable of predicting moisture loss regardless of the shape and microwave power input. A microwave heating model was developed by coupling electromagnetic and heat transfer physics using a commercial finite element code. The modeling results predicted heating time behavior consistent with experimental results as influenced by electromagnetic fields, waveguide size and microwave power absorption. The microwave heating modeling accurately predicted average temperature increase for 100 cm3 water domain at 360 and 840 W microwave power inputs. By dividing the energy absorption by the heat of vaporization, the amount of water evaporation in a specific time increment was predicted leading to a novel method to predict drying. Using this method, the best time increments, and other parameters were determined to predict drying. This novel method predicts the time to dry cellulose foams for a range of sample shapes, parameters, material parameters. The model was in agreement with the experimental results.
Optimal Scheduling of the Peirce-Smith Converter in the Copper Smelting Process
Authors: Ahmed Hussain , Ricardez-Sandoval Luis , Vilkko Matti
Published: November 2021

Copper losses during the Peirce-Smith converter (PSC) operation is of great concern in the copper smelting process. Two primary objectives of the PSC are to produce blister copper with a shorter batch time and to keep the copper losses at a minimum level. Due to the nature of the process, those two objectives are contradictory to each other. Moreover, actions inside the PSC are subject to several operational constraints that make it difficult to develop a scheduling framework for its optimal operation. In this work, a basic but efficient linear multi-period scheduling framework for the PSC is presented that finds the optimal timings of the PSC operations to keep the copper losses and the batch time at a minimum level. An industrial case study is used to illustrate the effectiveness of the proposed framework. This novel solution can be implemented in other smelting processes and used for the design of an inter-PSC scheduling framework.
Quranic Christology in Late Antiquity. ‘Isa ibn Maryam and His Divine Power (Energeia) in the Islamic Revelation
Authors: Demichelis Marco
Published: November 2021

Christology and monotheism have been dogmatically linked in the long history of Islam-Christian dialogue since the beginning of the 8th century. The Qur’an, in an analytical perception of religious otherness, specifically in relation to Christianity, assumed a dual discernment: on the one hand, it adopts a sceptical position because Christians are assimilationist (2: 120, 135, 145; 5: 51), sectarian and made Jesus the son of God (4: 171; 5: 14–19, 73; 9: 30; 18: 4–5; 21: 26); on the other hand, they are commended over the Jews and ‘Isa ibn Maryam has been strengthened with the Holy Spirit by God himself (2: 59, 62, 87, 253; 3: 48; 5: 47, 73, 82, 85, 110). The importance of enforcing the consciousness of a Quranic Christology, specifically where it concerned the potential influence that Christological doctrines such as adoptionism and monoenergism had on early Islam in late antiquity, where it was based on the proto- Islamic understanding of Jesus, and where it was rooted in Patristic orthodox-unorthodox debates, fell into oblivion. How was the Quranic canonization process affected by the ongoing Christological debates of the 7th century? Could Heraclius’ monoenergism have played a concrete influence on Quranic Christology? And in which way did early Kalam debates on God’s speech and will remain linked to Quranic Christology?
Acrylamide Content in Breast Milk: The Evaluation of the Impact of Breastfeeding Women’s Diet and the Estimation of the Exposure of Breastfed Infants to Acrylamide in Breast Milk
Authors: Mojska Hanna , Gielecińska Iwona , Winiarek Joanna , Sawicki Włodzimierz
Published: November 2021

Acrylamide in food is formed by the Maillard reaction. Numerous studies have shown that acrylamide is a neurotoxic and carcinogenic compound. The aim of this study was to determine the level of acrylamide in breast milk at different lactation stages and to evaluate the impact of breastfeeding women’s diet on the content of this compound in breast milk. The acrylamide level in breast milk samples was determined by LC–MS/MS. Breastfeeding women’s diet was evaluated based on the 24 h dietary recall. The median acrylamide level in colostrum (n = 47) was significantly (p < 0.0005) lower than in the mature milk (n = 26)—0.05 µg/L and 0.14 µg/L, respectively. The estimated breastfeeding women’s acrylamide intake from the hospital diet was significantly (p < 0.0001) lower than that from the home diet. We found positive—although modest and borderline significant—correlation between acrylamide intake by breastfeeding women from the hospital diet µg/day) and acrylamide level in the colostrum (µg/L). Acrylamide has been detected in human milk samples, and a positive correlation between dietary acrylamide intake by breastfeeding women and its content in breast milk was observed, which suggests that the concentration can be reduced. Breastfeeding women should avoid foods that may be a source of acrylamide in their diet.

Published: November 2021

A chimeric, bispecific Janus lectin has recently been engineered with different, rationally oriented recognition sites. It can bind simultaneously to sialylated and fucosylated glycoconjugates. Because of its multivalent architecture, this lectin reaches nanomolar avidities for sialic acid and fucose. The lectin was designed to detect hypersialylation—a dysregulation in physiological glycosylation patterns, which promotes the tumor growth and progression of several cancer types. In this study, the characteristic properties of this bispecific Janus lectin were investigated on human cells by flow cytometry and confocal microscopy in order to understand the fundamentals of its interactions. We evaluated its potential in targeted drug delivery, precisely leading to the cellular uptake of liposomal content in human epithelial cancer cells. We successfully demonstrated that Janus lectin mediates crosslinking of glyco-decorated giant unilamellar vesicles (GUVs) and H1299 lung epithelial cells. Strikingly, the Janus lectin induced the internalization of liposomal lipids and also of complete GUVs. Our findings serve as a solid proof of concept for lectin-mediated targeted drug delivery using glyco-decorated liposomes as possible drug carriers to cells of interest. The use of Janus lectin for tumor recognition certainly broadens the possibilities for engineering diverse tailor-made lectin constructs, specifically targeting extracellular structures of high significance in pathological conditions.
Puzzling Low-Temperature Behavior of the Van Der Waals Friction Force between Metallic Plates in Relative Motion
Authors: Dedkov George
Published: November 2021

This paper presents the results of calculating the van der Waals friction force (dissipative fluctuation-electromagnetic force) between metallic (Au) plates in relative motion at temperatures close to 1 K. The stopping tangential force arises between moving plates along with the usual Casimir force of attraction, which has been routinely measured with high precision over the past two decades. At room temperatures, the former force is 10 orders of magnitude less than the latter, but at temperatures T<50 K, friction increases sharply. The calculations have been carried out in the framework of the Levin-Polevoi-Rytov fluctuation electromagnetic theory. For metallic plates with perfect crystal lattices and without defects, van der Waals friction force is shown to increase with decreasing temperature as T−4. In the presence of residual resistance ρ0 of the metal, a plateau is formed on the temperature dependence of the friction force at T→0 with a height proportional to ρ0−0.8. Another important finding is the weak force-distance dependence ~a−q (with q<1). The absolute values of the friction forces are achievable for measurements in AFM-based experiments.

Published: November 2021

Intranasal immunization with whole inactivated virus (WIV) is an important strategy used for influenza prevention and control. However, a powerful mucosal adjuvant is required to improve nasal vaccine efficacy. Riboflavin, as a food additive with the advantages of being safe and low-cost, widely exists in living organisms. In this paper, the mucosal adjuvant function of riboflavin was studied. After intranasal immunization with H1N1 WIV plus riboflavin in mice, we found that the mucosal immunity based on the secretory IgA (sIgA) levels in the nasal cavity, trachea, and lung were strongly enhanced compared with H1N1 WIV alone. Meanwhile, the IgG, IgG1, and IgG2a levels in serum also showed a high upregulation and a decreased ratio of IgG1/IgG2a, which implied a bias in the cellular immune response. Moreover, riboflavin strongly improved the protection level of H1N1 inactivated vaccine from a lethal influenza challenge. Furthermore, riboflavin was found to possess the capacity to induce dendritic cell (DC) phenotypic (MHCII, CD40, CD80, and CD86) and functional maturation, including cytokine secretion (TNF-α, IL-1β, IL-12p70, and IL-10) and the proliferation of allogeneic T cells. Lastly, we found that the DC maturation induced by riboflavin was dependent on the activation of the mitogen-activated protein kinase (MAPK) signaling pathway, which plays an important role in immune regulation. Therefore, riboflavin is expected to be developed as an alternative mucosal adjuvant for influenza nasal vaccine application.

Background: Massive vaccination campaigns have been undertaken globally to combat the spread of the Coronavirus Disease 2019 (COVID-19). While most COVID-19 vaccines have shown excellent efficacy and safety profiles in clinical studies, real-world monitoring of vaccine safety is still important. In this study, we aimed to investigate the early side effects of Pfizer-BioNTech (BNT162b2) mRNA vaccine in children between 12–18 years old in Saudi Arabia. Method: To investigate the side effects in children in this age range following the administration of either one or two doses of Pfizer-BioNTech (BNT162b2) mRNA vaccine, we conducted a retrospective, cross-sectional study using a self-administered online survey. General and demographic data were collected, and vaccine-associated side effects following vaccination were evaluated. Results: The study recruited a total of 965 eligible participants. Overall, 571 (60%) of the study participants reported at least one side effect following Pfizer-BioNTech (BNT162b2) mRNA vaccination. The most frequently reported side effects were pain or redness at the site of injection (90%), fatigue (67%), fever (59%), headache (55%), nausea or vomiting (21%), and chest pain and shortness of breath (20%). Joint or bone pain were reported less frequently among our participants (2%). Our data showed that more female participants reported side effects compared to male participants, with 52% and 48%, respectively. Side effects were more common after the second dose compared to the first dose in our study cohort. Conclusions: While 60% of the children (12–18 years old) who received Pfizer-BioNTech (BNT162b2) mRNA vaccine reported side effects, our data showed that these side effects were not different from those that were reported in the clinical trials which lasted only for a few days. Side effects were more common after the second dose. Larger epidemiological and molecular studies are needed to evaluate the safety and the effectiveness of COVID-19 vaccine in protection of children against SARS-CoV-2 reinfections.

Published: November 2021

Introduction: Episiotomy is an incision in the perineal area during the second stage of labor to facilitate delivery. Complications of perineal injuries are one of the most important health issues. Oak pair has long been used experimentally to heal wounds and reduce pain. The present study was performed to investigate the effect of oak pair (Quercus infectoria) cream on pain due to episiotomy in nulliparous women. Methods: This double-blind clinical trial experimental study was performed on 120 nulliparous women in Asali hospital in 2018. Individuals were randomly divided into oak pair cream, placebo, and normal saline groups. Data were collected by demographic and midwifery information questionnaires and numerical pain scales. The creams were used by the participants every 12 hours for 10 days, and the pain intensity was evaluated before the intervention and on days 1, 5, and 10. Data analysis was performed by SPSS using chi-square, Kruskal-Wallis, and one-way analysis of variance (ANOVA) tests. Results: There was no statistically significant difference in pain intensity scores among the three groups of oak pair, placebo, and normal saline before the intervention (P = 0.20). Pain intensity on days 1, 5, and 10 after the intervention showed a significant difference between the three groups in favor of oak cream (P < 0.001). The results showed that there was a significant decrease in the mean pain intensity score of the oak pair receiving group over time (P < 0.001).Conclusion: Oak cream might be effective in reducing pain caused by episiotomy due to analgesic properties.

Published: November 2021

This paper illustrates a case study of teaching and research applied to the abandoned mining landscapes of the Sulcis area, located in the south-east side of Sardinia, one of the poorest in Europe. Although the region’s critical condition in the present, the area is nevertheless extremely rich in fascination and history. It offers unique natural landscapes, mostly pristine, a variety of archeological sites and, as mentioned, the ruins of the mining installations. All of this makes fore-seeable a concrete possibility of regeneration for the area, based on tourism, one of the island primary resources. The local institutions of Sulcis started a partnership with the University of Cagliari aiming to pursuit not just a practical and economical outcome in the immediate present, more a cultural and deeper rescue with a wider perspective. In the following pages, we present our academic activities in this mark and how we managed to guarantee fruitful superpositions of pedagogy, design, and research in our work within this kind of cooperation.Our focus is, therefore, the relationship between researching and teaching activities and the actions in support of the territory, pursued in a joint venture with the political institution. During these experiences, we defined a strategy to intercross these different layers, bringing the real and concrete dimension into our classroom, sharing our work with the students, and, at the same time, transferring the fruits of the teaching experiences to the territory. The correspondence between these two levels is not free of ambiguity and contradictions, however, we are convinced that it might show very important and fruitful outcomes.

Authors:   KU Leuven, Belgium, Schaeverbeke Robin , Vroman Liselotte ,   KU Leuven, Belgium
Published: November 2021

Our hunch is that movement is a valuable form of communication which may expose new insights concerning spatial experiences which might of use in architectural design processes. In that sense investigating movement visualisations and notations can be a way to reveal new knowledge related to spatial qualities, as well as qualities related to embodied experience. These reflections were the motive to set up Mapping, Drawing, Visualising the Experienced as a research-based master elective. In this elective, we investigated how existing movement visualisations and notations could be a manner to explore and reveal new knowledge and insights related to spatial qualities, as well as qualities related to the embodied spatial experience and subsequently how these insights can enrich the architectural design process. Within this paper, we elaborate on the context, content and the intention of the course and critically reflect on the obtained results.

Authors: Bien Tomasz
Published: November 2021

The paper describes the research on the method of production of granulated phase-change materials (PCM) used in construction industry for the accumulation of thermal energy. As mineral materials for the granules preparation zeolite from fly ash Na-P1 and natural diatomite dust were used which were impregnated with paraffinic filtration waste and granulated using a combined granulation method. Obtained granules were characterized using X-ray diffraction (XRD), scanning electron microscopy (SEM), nitrogen adsorption/desorption isotherm, and differential scanning calorimetry (DSC). Mechanical strength of the materials was determined in a “drop strength” test. Performed analyses revealed that mineral composition and micromorphology of the diatomite and zeolite granules were varied, with zeolite granules having higher mechanical strength.

Published: November 2021

We have prepared Tl-doped NH4Br translucent ceramics by spark-plasma sintering and evaluated their photoluminescence (PL) and photostimulated luminescence (PSL) properties. In PL, two luminescence peaks appeared due to 3P1 → 1S0 transitions of Tl+ and off-center self-trapped excitons (STEs) localized around Tl+ in all the samples. In PSL, the 0.1%–3% Tl-doped samples showed luminescence related to the off-center STEs around 500 nm by stimulation light at 630 nm. When correlations between exposure dose and PSL intensity were examined, we confirmed that the 0.1%–1% and 3% Tl-doped samples showed linear responses over ranges of 10–10 000 and 1–10 000 mGy, respectively.

This study aimed to evaluate the growth and yield of two potato genotypes (S) due to three sources of nitrogen (G) fertilizer on medium plains. The study was arranged in a two-factor, randomized block design factorial and was repeated three times. The first factor is the source of N fertilizer, consisting of three levels: S1 = ZA ((NH4)2SO4), S2 = urea (CO(NH2)2), and S3 = ammonium nitrate (NH4NO3). The second factor was potato genotype, consisting of two levels G1 = MS 13 genotype and G2 = At 4 genotype. The data obtained were analyzed by F test at 5% level (ANOVA) to determine the effect of treatment and further LSD test was carried out to determine differences between treatments, and multiple regression analysis to determine the most influential factors on potato tuber starch content. The results showed that the highest starch content was obtained by the At 4 genotype of 18,50% and was suitable for medium plains. While the starch content of the MS 13 genotype was 17,53%. For fertilizing nitrogen sources, it is recommended to use ammonium nitrate, because it obtains the highest yield of 27,30 tons ha-1 from other nitrogen fertilizer sources.

Authors: Souza Teixeira Maria Dilma , Silva Carvalho Marta Cristina
Published: November 2021

A elevada geração de resíduos orgânicos, aliada à destinação inadequada dos mesmos, bem como a falta de educação ambiental, contribui drasticamente para o caos socioambiental. O presente estudo objetivou analisar a conduta dos residentes do povoado Vale do Paraíso, Seabra/BA acerca da destinação do lixo orgânico, além de promover a educação ambiental nesse quesito. Após uma análise, foi estruturada a composteira piloto com mais de 10 famílias. A estrutura foi constantemente monitorada, utilizando- se folhas de bananeira como proteção contra encharcamento pelas chuvas, além do revolvimento periódico. O húmus obtido foi destinado para a adubação de hortaliças e plantas ornamentais. Pôde-se notar a satisfação dos moradores ao constatar a qualidade do composto. Ademais, houve uma mudança positiva no comportamento da população quanto ao descarte do lixo orgânico, havendo ainda a construção de uma segunda composteira para que os moradores da comunidade dessem continuidade às práticas de compostagem.

Remoção de fármacos do esgoto em reatores biológicos com biomassa fixa e suspensa: uma revisão
Authors: Silveira Amaro da Silva Alexandre , Lopes Cunha Deivisson , Marques Marcia
Published: November 2021

A contaminação por micropoluentes (MPs) é um desafio para a gestão de recursos hídricos, pois mesmo em baixas concentrações tais substâncias podem causar danos a ecossistemas aquáticos e ao homem. ETEs convencionais não foram projetadas para remoção de MPs, e o aprimoramento de sistemas biológicos é atualmente discutido em todo o mundo. Estudos mostram que, em comparação com os sistemas convencionais como Lodos Ativados, a utilização combinada de biomassa fixa e suspensa pode aumentar a remoção de MPs. A tecnologia de reatores de leito móvel com biofilme (MBBR) tem sido empregada em sistemas híbridos, com vistas ao aprimoramento dessas ETEs. Estudos relatam que a contribuição dos biofilmes ocorre por meio de mecanismos distintos dos observados com a biomassa em suspensão. Esta revisão objetivou compilar informações sobre o papel das biomassas fixas e suspensas na remoção de fármacos, com foco na tecnologia MBBR. A eficiência superior de sistemas híbridos estaria relacionada à maior diversidade de condições e de processos biológicos de degradação, onde os dois tipos de biomassa atuariam de forma complementar.

Published: November 2021

This work is the first part of a national review about Bank Filtration (BF) that began in 2003, in Brazil. These studies were conducted in the laboratory and in the field with water and natural sediment from the study regions, showing how BF has been efficient worldwide for the treatment of water for public supply as an alternative treatment. It aims to show the synthesis of results to date and point out its main benefits and challenges; that is, the state of the art at the national level. The review is concentrated in Santa Catarina (part 1), Pernambuco and Minas Gerais (part 2). BF demonstrates efficiency in reducing parameters such as turbidity and coliforms (total and fecal), pesticides and toxins. However, BF showed low capacity in reducing parameters such as salinity and true color. BF is highly dependent on local geological conditions, so parameters such as iron, manganese, fluorine, alkalinity, hardness, and chlorides can be added to the treated water.

Published: November 2021

O Brasil é formado em sua maioria por municípios de pequeno porte, sendo que grande parte da população vive em comunidades desprovidas de acesso a um sistema de coleta e tratamento de esgoto centralizado e de qualidade. O objetivo foi realizar uma revisão sistemática para analisar o uso das diferentes tecnologias e sistemas de tratamento descentralizados de esgotos domésticos no Brasil e comparar os valores de lançamento com os limites estabelecidos na Legislação Brasileira. Para essa revisão foram pesquisados 30 sistemas de tratamento de esgoto doméstico descentralizados no Brasil de 2006-2018. Os sistemas que mais atenderam aos limites de lançamento de efluentes da Legislação Nacional, em sua maioria, possuíam tratamento terciário. No entanto, foi possível concluir que muitos desses sistemas ainda necessitam de um aprimoramento de tecnologia para maior remoção dos nutrientes.

Monitoramento e caracterização físico-química da matéria orgânica e de enxofre em efluente do tratamento anaeróbio
Authors: Ivo Soares e Silva Pedro , Soares Bias Gerlandia , Vasiljevic Mendes Matias Bezerra Iasmyn , Tavares de Sousa José
Published: November 2021

O estudo tem como objetivo avaliar o tratamento de esgoto doméstico por processo anaeróbio em relação à conversão das frações de enxofre e remoção de matéria orgânica, também considerando as frações de nitrogênio e outros parâmetros. O sistema consiste em um reator anaeróbio UASB convencional, tanque de equalização e filtro de areia com fluxo intermitente. Os resultados mostraram que na primeira fase obteve-se uma remoção de 63% de matéria orgânica e 77,3% de turbidez e acréscimo na concentração de sulfeto. Portanto, compreendendo as informações acerca da implantação e da operação, comprova-se a viabilidade do emprego de tratamento anaeróbio combinado com um pós-tratamento para esgoto doméstico.

Estudos indicam que a prática de exercícios físicos é benéfica à saúde de todas as pessoas, dentre elas as gestantes. Em relação a esse público específico, já é disseminado que exercícios aeróbicos de intensidade moderada impactam positivamente sobre as taxas de parto cesáreo, diabetes e hipertensão gestacional, controle do peso materno e relação direta sobre a depressão pré e pós-natal. E que os exercícios de força também não oferecem riscos mesmo no terceiro trimestre. No entanto, poucos são os estudos que avaliaram os efeitos do exercício de alta intensidade nesta população. O objetivo deste estudo é através de um ensaio teórico apresentar perspectivas sobre a prática de exercícios de alta intensidade em gestantes. Foram selecionados artigos utilizando as bases de dados do Google Scholar, Scientific Electronic Library Online (SciELO), US National Library of Medicine National Institutes of Health (PUBMED) e a Biblioteca Virtual em Saúde (BVS). Foram também denominadas palavras chaves para a busca dos trabalhos seguindo as recomendações do site Descritores em Ciências da Saúde (DeCS). As palavras foram: gestantes, treinamento intervalado de alta intensidade e saúde. Foram selecionados artigos científicos nacionais e internacionais. Com prioridade a utilização de artigos em inglês. O presente ensaio sugere que a prática de exercícios de alta intensidade pode ser considerada segura e eficaz para a prática de gestantes, entretanto vale ressaltar a relevância de ser bem planejada e com o acompanhamento de um profissional qualificado.
