Authors: Pipitò Ludovico , Rujan Roxana M. , Reynolds Christopher A. , Deganutti Giuseppe
Published: March 2022

The protein responsible for the first steps of SARS-CoV-2 cell invasion, the spike protein, has received much attention in light of its central role during infection. Computational approaches are among the tools employed by the scientific community in the enormous effort to study this new threat. Molecular dynamics (MD) in particular, has been used to characterize the function of the spike protein at the atomic level and unveil its structural features from a dynamic perspective. Here, we review the main findings of MD studies on the spike protein, including flexibility of the stalk region, the role of the glycans on the surface of the S protein, the effect of mutations on biding to ACE2, the change from the down conformation to the up conformation, and progress in drug repurposing.
Low Salinity Water and Foam Flooding in Sandstone Reservoirs Bearing Heavy Oil
Authors: Al-Saedi Hasan Naeem
Published: March 2022

This study investigates foam and water flooding (especially low salinity (LS) water flooding). Generally, injecting LS water alters sandstone wettability towards being more water-wet, is an effective EOR technique that improves oil recovery. Foams were also employed to enhance oil recovery due to its ability to increase residual oil mobility and sweep efficiency. Combining both LS water and foam into a novel attempt that takes advantage of the relative strengths of both EOR methods. This EOR combination was tested on Berea sandstone cores saturated with heavy oil. The ultimate outcome from this work is a “recipe” of EOR methods in combination, which utilizes LS water and foam to achieve recovery of over 72.65 percent of OOIP in core flooding tests. The core-flooding results showed that an increased heavy oil recovery was obtained by injecting foam and lowering water salinity. The contact angle and interfacial tension (IFT) measurements agreed with the core-flooding results.

From molecular adsorption to decomposition of methanol on various ZnO facets: A Periodic DFT study.
Authors: mehta Shweta , Joshi Kavita
Published: March 2022

Methanol is an interesting and important molecule to study becauseof its potential to replace existing fuels. It is also a prominent hydrogen source which can be used to generate hydrogen in-situ. ZnO is widely used as catalyst in synthesis of methanol from CO2 at industrial scale. In this work, we demonstrate that the same catalyst could be used for MeOH decomposition. We have carried out a systematic study of interaction of methanol with various flat and stepped facets of ZnO by employing Density Functional Theory (DFT). Two flat [(1010)and (1120)] and two stepped [(1013) and (1122)] facets are investigated in detail for methanol adsorption. Chemisorption of MeOH with varying strength is common to all four facets. Most importantly spontaneous dissociation of O-H bond of methanol is observed on all facets except (1120). Our DFT calculations reveal that molecular adsorption is favored on flat facets, while dissociation is favored on step facets. Also, (1010) facet undergoes substantial reconstruction upon MeOH adsorption. Activation of C-H bond along with strengthening of C-O bond on ZnO facets suggest partial oxidation of methanol. With our DFT investigations, we dig deeper into the underlying electronic structure of various facets of ZnO and provide rationale for the observed facet dependent interaction of ZnO with MeOH.
The Behavior of Methane-Water Mixtures Under Elevated Pressures Using Many-Body Potentials
Authors: Naden Robinson Victor , Ghosh Raja , Egan Colin E. , Riera Marc , Knight Christopher , Paesani Francesco , Hassanali Ali
Published: March 2022

Non-polarizable empirical potentials have been shown not to be able to capture the mixing of methane–water mixtures at elevated pressures. Although DFT-based ab initio simulations may circumvent this discrepancy, they are limited in terms of the relevant time and length scales associated with mixing phenomena. Here we show that the many-body MB-nrg potential, designed to reproduce methane–water interactions with coupled cluster accuracy, successfully captures this phenomenon up to 3 GPa and 500 K with varying methane concentration. Two-phase simulations and long time scales that are required to fully capture the mixing, affordable due to the speed and accuracy of the MBX software, are assessed. Constructing the methane–water equation of state across the phase diagram shows that the stable mixtures are denser than the sum of their parts at a given pressure and temperature. We find that many-body polarization plays a central role, enhancing the induced dipole moments of methane by 0.20 D during mixing under pressure. Overall, the mixed system adopts a denser state, which involves a significant enthalpic driving force as elucidated by a systematic many-body energy decomposition analysis.
Using core-hole reference states for calculating X-ray photoelectron and emission spectra
Authors: Dreuw Andreas , Fransson Thomas
Published: March 2022

For the calculation of core-ionization energies (IE), X-ray photoelectron spectroscopy (XPS), and X-ray emission spectroscopy (XES), a commonly applied approach is to use non-Aufbau reference states with a core-hole as either final (IE and XPS) or initial (XES) state. However, such reference states can introduce numerical instabilities for post-HF methods, relating to the denominator of the energy corrections involved. This may become arbitrarily close to zero if a negative virtual MO is present, e.g. a core-hole, leading to near-singularities. The resulting instabilities lead to severe convergence issues of the calculation schemes and, in addition, can strongly affect both energies and intensities, with oscillator strengths seen to reach values up to 4 × 10^7. For the K-edge we propose freezing the highest-energy virtual orbitals which contribute to any denominator below a threshold of 0.1 Hartree. Stable and reliable spectra are then produced, with minimal influence due to freezing energetically high-lying virtual orbitals (typically removing <5% of the total number of MOs). The developed protocol is here tested for Møller–Plesset perturbation theory and for the algebraic diagrammatic construction scheme for the polarization propagator, but it is also relevant for coupled cluster theory and other related methods.

Authors: Arcanjo Fagundes Gilberto , Soares Pinto Nadine , Severo Joseana , Hansel Michelotti Adriana Aparecida , Walter Melissa
Published: March 2022

A fome oculta ocorre quando o consumo e/ou absorção de micronutrientes é insuficiente para sustentar o correto desenvolvimento. A carência de vitamina A pode causar deficiência visual, aumento do risco de desenvolvimento de doenças graves e morte em crianças. O β‑caroteno (precursor da vitamina A) é um carotenoide presente em cultivares de batata-doce biofortificadas (BDB), que apresentam polpa alaranjada. Foram investigados materiais de domínio público, em bases de dados digitais, buscando assuntos relacionados à deficiência de vitamina A em crianças e à ingestão diária recomendada (IDR), assim como produtos alimentícios obtidos a partir de BDB e teor de β‑caroteno em variedades e produtos elaborados com batatas cultivadas no Brasil. A partir dos dados obtidos foram apresentados: as condições de processamento, concentração de β‑caroteno e quantidade necessária para suprir a IDR de vitamina A em crianças de cada produto (batata-doce ou alimento) avaliado. Foram tabelados vinte produtos, cujos teores de β‑caroteno variaram entre 0,17 e 3,79 mg β‑caroteno/100 g, sendo necessária uma porção de 65 g do cultivar da BDB para suprir a IDR (400 µg RE/dia) de vitamina A de crianças de até seis anos. O consumo dos produtos alimentícios preparados com BDB variaram entre 830 g e 71 g, demonstrando que a forma de preparo, como o uso do calor aliado à exposição ao O2, pode resultar em degradação dos carotenoides. O desenvolvimento de produtos alimentícios com altos teores de β‑caroteno apresenta-se como uma alternativa viável para a inserção do BDB. As condições de consumo também devem ser levadas em consideração, visando a melhorar a bioacessibilidade e a biodisponibilidade e a combater a deficiência de vitamina A.
He Whiringa Muka: The Relationship between the Whanganui River, Marae, and Waiata
Authors:   , Haami Meri
Published: March 2022

The relationship between the Whanganui River, Rānana Marae, and waiata are layered interconnections that speaks to a unique positionality, view, and lived experience for those who descend from this region. This thesis seeks to uncover the mechanisms of these three sites of research by drawing on Kaupapa Māori, Tupua Te Kawa from Te Awa Tupua, ecomusicology and performative ethnography. Coinciding with these methodologies are the ethical frameworks, tikanga Whanganui and Whanganui kaiponu, which all inform the use of wānanga as a way of gathering knowledge, enabling the voices of the descendants of Rānana Marae to emerge. These discussions were analysed using thematic analysis and contextualised amongst interdisciplinary spaces. These include whakapapa, Māori oral tradition and histories, ecomusicology, orality, waiata performance and pedagogies, ethnomusicology, colonisation, and racism.

Through the study emerged a story that recounted and recontextualised the pā auroa and hīnaki from Te Awa Tupua. The pā auroa and hīnaki are not only a means of past sustenance through providing food for Whanganui iwi, but they embody a conceptual and theoretical strategy for creating a healthy succession infrastructure surrounding waiata as a health indicator of one’s whakapapa/connection to the environment and themselves. Further, this study provides a Kaupapa Māori ecomusicological framework called, ‘he whiringa hīnaki’ that draws on the lived experiences from descendants of Rānana Marae to contribute towards future generations who wish to examine waiata within its environmental and ancestral contexts. In weaving these many threads together, Kaupapa Māori and ecomusicological practices brought healing by showing how waiata connects peoples and place while adding to collective and individual well-being. This research arose future implications in how past wisdoms embedded within waiata of tūpuna inform how Rānana Marae continue to navigate the future surrounding succession.

Authors: Çaylan Nilgün , Kiliç Melek , Yalçin Sıddıka , Tezel Başak , Kara Fatih
Published: March 2022

Background: The Baby-Friendly Hospital Initiative (BFHI) is a World Health Organization and United Nations Children’s Fund joint global programme to protect, promote and support breastfeeding. Sustainability of the BFHI standards is important for health facilities and country-level implementation. Aims: To analyse the 2018–2019 external reassessment results of baby-friendly hospitals (BFHs) in Turkey. Methods: We included 414 BFHs. The Ten Steps to Successful Breastfeeding were divided into 2 groups: critical management procedures (Steps 1 and 2) and key clinical practices (Steps 3–10). Results: All 10 steps were fulfilled by 60.1% of the hospitals. Steps 3 and 2 had the lowest compliance rates (81.6% and 85.7%), and Steps 7 and 8 had the highest rates (97.1% and 98.1%). Caesarean section rates in the fourth quartile were associated with significantly lower adherence to Steps 3 and 10. The presence of another external reassessment within 5 years was associated with a significantly higher adherence rate to Step 3, and a significantly higher full implementation rate for the clinical practices. Hospitals that fully implemented management procedures had a significantly higher fulfilment percentage for all clinical practices. The western region had higher adherence rates for all the clinical practices than other regions. Conclusion: Reassessments seem useful for sustainability. Full compliance with Steps 1 and 2 is important for higher adherence to the clinical steps. Regional variations should be taken into account in the implementation of the programme.

Published: March 2022

Background: The sustained growth of older people and the epidemiological shift from communicable to chronic health problems have attracted increased attention to geriatric wellbeing, including oral health. Aims: To evaluate the oral health of urban community-dwelling older people and identify their priority oral health needs. Methods: We recruited 352 adults aged ≥ 65 years in 2015 from social organizations and primary healthcare centres in Beirut and its suburbs. Older people underwent dental examination including the decayed, missing and filled teeth (DMFT) score, gingival health [plaque index (PI) and Periodontal Screening and Recording (PSR)], and dental functional units (FUs). Sociodemographic data were gathered through a structured questionnaire in a face-to-face interview. The participants were stratified into 3 age groups, and according to restoration with partial, complete and no dentures. Statistical analyses included the Mann–Whitney, Kruskal–Wallis and χ2 tests to explore the oral health status by sociodemographics. Results: Missing teeth contributed most to high DMFT score . Mean PI and root caries indices were high. Mean FU scores were low, but higher in women and in complete denture wearers. Lower numbers of remaining mandibular anterior and maxillary posterior teeth, higher DMFT scores, but better periodontal status (lower PSR scores) were found in the older age groups. The more educated participants exhibited the healthier scores. Conclusion: We observed poor oral health, particularly missing teeth and low FUs, in older people, warranting interventions to integrate oral health within the scope of geriatric general health.

Authors: Mulyani R Henny
Published: March 2022

Karburisasi merupakan suatu proses perlakuan termo kimia yang dilakukan untuk mengeraskan permukaan baja dengan menambahkan unsur karbon pada permukaannya sehingga terbentuk fasa martensit yang memiliki sifat kekerasan yang lebih baik dibanding matriksnya. Umumnya proses ini dilakukan pada baja yang memiliki kadar karbon yang rendah sehingga tidak bisa dikeraskan dengan proses celup cepat.

Karburisasi padat (pack carburazing) merupakan metoda karburisasi yang paling sederhana dengan menggunakan serbuk arang sebagai sumber karbon yang diharapkan akan berdifusi ke dalam permukaan baja. Proses ini dilakukan dengan pemansan pada temperatur 900oC selama 2 jam kemudian diikuti dengan pendinginan celup cepat di dalam air.. Material yang digunakan adalah baja pegas JIS SUP 6 yang memiliki kadar karbon 0,6%C. Dari hasil pengujian kekerasan menunjukkan kekerasan setelah proses karburasi lebih tinggi dengan nilai kekerasan 440 Hv dibanding sebelum proses dengan 180 Hv. Sedangkan fasa yang dihasilkan dari proses ini adalah fasa martensit.

Verdade, mentira e liberdade
Authors: Kothe Flávio R.
Published: March 2022

Ter uma noção mais clara sobre o que possa ser a verdade é central não só para a ciência, também não só para a filosofia, mas também para a arte. Há uma longa tradição filosófica que diz, com Aquino, que o belo é o resplendor da verdade ou, com Hegel, que o belo é a aparição sensível da ideia. Para o idealismo alemão, a ideia tinha de ser verdadeira, pois se não ela seria apenas um palpite infeliz. Como a verdade permite distinguir o que é justo e correto, o que vale e o que não tem valor, ela também é central para a vida das pessoas, para as grandes decisões que precisam tomar e para a estruturação do seu dia a dia.

A numerical approach to evaluating the asymmetric ground settlement response to twin-tunnel asynchronous excavation
Authors: Seghateh Mojtahedi Alireza , Nabizadeh Ali
Published: March 2022

Due to the importance of surface and subsurface settlements to prevent damages to building foundations and sensitive structures in the urban cities, in this study, the ABAQUS finite element software has used to conduct a series of numerical modeling analysis on ground surface settlement caused from the asynchronous excavation of twin-tunnel. The effects of tunnel diameter, center-to-center tunnel spacing, and tunnel depth are discussed in detail and the shape of the surface settlement curves is also plotted. The numerical modeling has been verified by the results of three sequential twin-tunneling centrifuge tests conducted by the City University of London with 94.22%, 98.71% and 99.56% accuracy, respectively. Based on the results of this study, reducing the tunnel diameter decreases the amount of the maximum ground surface settlements and reducing the depth of tunnels and the distance between twin-tunnel to less than 2D (D is the diameter of the tunnels) increase the maximum surface settlements. Installation of 30 cm of tunnel lining can decrease the maximum ground surface settlement up to almost 79%.

Clinical Effectiveness of Various Surgical Reconstruction Modalities for Acute ACJ Separation: Protocol for a Systematic Review and Meta-Analysis
Authors: Hartland Alexander W. , Nayar Sandeep Krishan , Teoh Kar Hao , Rashid Mustafa S.
Published: March 2022

Introduction:

Acute acromioclavicular joint separation is a common injury to the shoulder. Various surgical reconstruction methods exist when operative management is required, but the optimal procedure is not known. The aim of this systematic review and meta-analysis is to review the literature to assess the clinical effectiveness of various surgical reconstruction modalities used for acute ACJ separation.

Methods:

The study protocol was designed and registered prospectively on PROSPERO (International prospective register for systematic reviews). Literature search will include MEDLINE, EMBASE, PsycINFO, and The Cochrane Library electronic databases. Randomised controlled trials (RCTs) evaluating surgical procedures for acute acromioclavicular joint (ACJ) separation will be included. Our primary outcome is any functional patient-reported outcome measure related to the shoulder. Secondary outcomes may include radiological measurements, objective measurements of strength testing, range of motion, other patient-reported outcome measures not specific to the shoulder such as the Visual-Analog Scale (VAS) for pain, timelines for return to sport or work, and rate of complications. Risk of bias will be assessed within each study using The Cochrane Risk of Bias Tool 2.0 and the Jadad score. Inconsistency and bias across included studies will be assessed statistically. Comparable outcome data will be pooled and analysed quantitatively or qualitatively as appropriate.

Ethics and dissemination:

This study did not require ethical clearance. We plan to publish this systematic review and meta-analysis in a peer-reviewed journal and present the results at various national and international conferences.

Highlights
Lo spazio dellavoluntassenecana: tra filosofia e tragedia
Authors: Cassan Melania
Published: March 2022

The aim of this paper is to examine the cogency of the Senecan notion ofuoluntasin the development of passion (with reference toDe ira2.4) also showing a possible ‘transposition’ of the concept within Seneca’s tragedies, precisely in theMedeaand in thePhaedra. Specifically, we firstly propose to explain what characteristics are entailed by the development of theadfectus, highlighting the centrality of the notion ofuoluntas non contumax. Subsequently, we rely on our analysis to present an interpretation of the famous monologues of Medea and Phaedra (Med. 937-44 andPhaed. 602-5). To reread the tragedies in light of the theoretical background refined in the De ira allows not only to further investigate the psychological mechanisms related to uoluntas but ultimately also to show a possible element of proximity between the author’s philosophical and tragic works.

Authors: MERCAN Gamze , KÖSEOĞLU Pınar
Published: March 2022

The purpose of this study is to determine how effectively biology instructors at high schools connected with the Ministry of National Education identify trees in their immediate surroundings in the context of trees, which are critical to the notion of biodiversity. The population comprises of biology instructors who worked in high schools in various regions of Turkey during 2020 and 2021 under the auspices of the Ministry of National Education. The research sampled 262 biology teachers volunteer using an accessible sampling technique. The research model is a relational one that is based on the general survey model, a quantitative research technique. Mercan and Köseoglu's (2019) "Given Tree Recognition (GTR) Test" was used to gather data for the study. The Mann Whitney U Test was used to compare matched groups and the Kruskal-Wallis H test was used to compare more than two groups in the analysis of the data collected throughout the study. According to the study's results, biology instructors' capacity to identify trees in their immediate surroundings is limited. It is deemed critical to ascertain biology instructors' degree of recognition of trees in their immediate surroundings, since the research's findings begin with an understanding of the importance of biodiversity, which is one of the most critical problems in the conceptual framework of biology teaching.

The artificial inoculation of broiler chickens the Hisex Brown cross with a three types of eimeria, the smallest body weight loss of chickens was in the group that received the ionophoric antibiotic lasalocid with feed, anti-coccidiosis drug decoquinat and the complex phytobiotic "AdiKox AR". The use of the ionophoric antibiotic monensin and the synthetic coccidiostatic drug robenidin showed the least sensitivity of eimeria to them, which adversely affected the body weight of broiler chickens. In the blood serum of chickens taken on the 20th day after their first vaccination at one day of age with the Nobilis ND C2 vaccine by the spray method against the associated with artificial infection with a mixture of eimeria at 10 days of age and preliminary prophylactic feeding of them with drugs from different pharmacological groups, specific immunity to Newcastle the disease was unevenly distributed among the groups. The weakest group immunity was observed in the group of infected control chickens that did not receive drugs. In all groups that received supplements of chemotherapeutic agents with food, with the group immunity indicator acceptable in the vaccine instructions, there were zero individual titers. The complex phytobiotic "AdiCox AR" stimulated the production of high group post-vaccination immunity in chickens against Newcastle disease (74%) without zero individual titers. For the eimeriosis prevention and high-quality vaccination of broiler chickens against Newcastle disease at the poultry farm of the Belgorod Region, we recommend feeding the complex phytobiotic "AdiKox AR" at a dose of 300 g/t of feed for 10 days or more. The use of lasalocide and decoquinate for the coccidiosis prevention in a poultry farm is permissible with the condition of rotation and monitoring of the sensitivity of eimeria to drugs. The use of monensin and robenidin, according to the results of the experiment, is considered inappropriate.

Authors: Perova N.A. , Golovin A.V.
Published: March 2022

In order to study the effect of the use of protected vegetable fat, prepared according to a specialized technology and contained calcium salts of vegetable fatty acids, in feeding of highly productive dairy cows on milk productivity, rumen digestion and reproductive indicators, we carried out a scientific and economic experiment at Lestekhstroy LLC (Moscow) on two groups of Holstein cows, 10 heads in each, during the first 100 days of lactation. It has been established that the inclusion of protected vegetable fat in the composition of the diets at a dosage of 500 g/head/day contributes to an increase in parameters of milk productivity of cows: the milk yield was higher by 188 kg, compared to control group, and therefore the average daily milk yield in the experimental group exceeded the control group by 5.4%, milk yield of 4% fat content in the experimental group was higher by 8.0% (PЈ0.05), compared with the control, the production of milk fat in the experimental group exceeded the control by 11, 0% (PЈ0.05), the production of milk protein in the experimental group exceeded the control by 5.8% (Pі0.05). It was shown that the use of protected fats contributed to a reducing the feed costs, expressed in ME, in the experimental group by 4.3%, compared with the control. The use of studied vegetable fats had a positive effect on rumen digestion through a tendency to increase the concentration of VFAs in the rumen fluid of the cows of the experimental group by 7.6% and microbial mass by 7.5% (Pі0.05), compared with the control. It was found that reproductive indicators of cows in experimental group were better, although the differences with the control were not statistically significant: the service period in the experimental group was 120.5 days, which is lower by 20.7 days, compared with the control group, the insemination index was lower in the experimental group compared to the control and amounted to 2.19.

Reflexiones, debates y análisis sobre políticas educativas: un marco social de interpretación común
Authors: Sandoval Vázquez Francisco , Enríquez Gutiérrez Gustavo Adolfo
Published: March 2022

El libro da cuenta de las políticas institucionales que se construyen en torno a la educación; el papel de la formación, el aprendizaje, la ense­ñanza, la evaluación en la educación, y la forma de pensar la actuación de los actores escolares en las instituciones educativas. Propone conversar y dis­crepar a fin de plantear fisuras, porosidades e intersticios sobre los proyec­tos educativos desde la mirada de académicos, investigadores y docentes. Comparte la mirada de Enrique Dussel sobre la política como proyec­to social, cuya función principal, es el reconocimiento de la comunidad de las personas, y su participación a favor del interés colectivo. Asume con Hannah Arendt, la política como la construcción de un mundo común donde todos participan activamente en la elaboración de su sentido. Siguiendo a Enrique Dussel, invita a pensar la política como el poder organizado, una fuerza voluntariamente asumida por todos a fin de crear instituciones democráticas. La política, en el texto; las políticas desarro­lladas, en los distintos materiales, buscan abonar ideas a la reflexión colec­tiva; a fin de construir un marco común donde dilucidar los imaginarios sociales instituidos sobre la educación, en favor del interés democrático. El libro está organizado en tres partes: «Reflexiones, debates y análi­sis», cuyo propósito es invitar a pensar con otros lectores sobre las políti­cas educativas en educación básica; la discusión sobre sus sentidos; en el marco social actual, y disertar; sobre la forma en que operan estás políti­cas en nuestra realidad mediata e inmediata a través de estudios de caso, contextos locales, realidades nacionales o regionales. Finalmente, el ma­terial conmina a su lectura, análisis, discusión y debate, a fin de construir colectivamente, nuevos sentidos sobre el gobierno de todos y con todos.

Zapatismos. Nuevas aproximaciones a la lucha campesina y su legado posrevolucionario
Authors: Barreto Zamudio Carlos , Crespo María Victoria
Published: March 2022

Esta obra propone un diálogo entre distintas generaciones estudiosas del zapatismo, a fin de permitir la diversificación de voces, metodologías, temas y enfoques particulares. El libro está estructurado en dos partes que articulan las diversas contribuciones. La primera, Zapatismos, propone un balance historiográfico a cien años del asesinato de Emiliano Zapata e incluye aproximaciones a la lucha campesina que proponen enfoques heterodoxos, incluyendo la perspectiva de género, la mirada regional, los estudios culturales y la dimensión simbólica del zapatismo. La segunda parte está dedicada a los estudios del legado posrevolucionario del zapatismo, principalmente en la región del Sur y en Morelos. Se aborda el legado del zapatismo en la institucionalización del Estado y la reforma agraria en Morelos. Los diversos trabajos incursionan en los vínculos del zapatismo con otros movimientos políticos y sociales del siglo XX, como el comunismo y el almazanismo. También se incluyen trabajos específicos sobre personajes posrevolucionarios con raíces zapatistas. El presente volumen se inscribe en el contexto de la conmemoración de los cien años del asesinato de Emiliano Zapata, plantea balances, revisiones y nuevas perspectivas historiográficas e incorpora una mirada interdisciplinaria de los zapatismos, no sin dejar abierta una reflexión sobre su repercusión en las luchas y resistencias comunitarias y campesinas contemporáneas.
