Ultrasound and Microwave-assisted Extraction of Proteins from Coffee Green Beans: Effects of Process Variables on the Protein Integrity
Authors: Prandi Barbara , Di Massimo Martina , Tedeschi Tullia , Rodríguez-Turienzo Laura , Rodríguez Óscar 
Published: September 2022

AbstractThe demand for proteins is constantly increasing and green extraction methodologies are needed to achieve environmental sustainability goals. The recovery of the by-products of the agri-food chain has also become a priority from a circular economy perspective. Some by-products are still little exploited for the extraction of proteins, such as coffee by-products. In this work, various innovative extraction technologies were applied to recover the protein fraction from the non-compliant coffee green beans (CGB), using a methodological approach that allowed to correlate the process parameters with the final quality of the extracted proteins. The ultrasound-assisted extraction (UAE) technique has been shown to have a minor impact on the quality of the proteins, thanks to the possibility of refrigerating the system, while the microwave-assisted extraction (MAE) shows a certain degree of degradation due to the high temperatures reached. The results indicate that strict temperature control is required during alkaline extraction to preserve the quality of the protein fraction.

Abstract
The main objective of this study was to test a structural theoretical model of the effects of self-regulated learning on academic stress, subjective well-being, and academic achievement in Secondary Education, considering academic procrastination as a mediator. An additional aim was to explore whether these relationships were moderated by gender and educational level. Participants were 728 students in compulsory and post-compulsory secondary education in a large city in Eastern Spain. Path analysis results indicated that the proposed model showed satisfactory fit, with the three dimensions of self-regulated learning significantly predicting the educational outcomes considered, and that procrastination mediated these relationships. Overall, the model is able to predict 9.8% of the variance of academic stress, 23.1% of students wellbeing, and 14% of academic achievement. Moreover, the multi-group routine revealed no moderation effects due to gender, but educational level moderated two relationships, between self-efficacy and academic achievement and between metacognitive strategies and procrastination. Additionally, supplementary models were tested for three specific subjects (Spanish Language, Foreign Language and Mathematics), which showed an improvement in explained variance, being respectively: 29%, 28% and 27%. Results are discussed in light of previous research and in terms of their impact on educational practice.
Nukes Under Water. U-Boot-gestützte Kernwaffen in Indien und Pakistan zwischen Stabilität und Instabilität
Authors: Heinrich Jens 
Published: September 2022

ZusammenfassungKernwaffen spielen in der Verteidigungspolitik Indiens und Pakistans eine immer stärkere Rolle. Beide Staaten rüsten auf und modernisieren ihre Nukleararsenale. Dieser Trend hat auch die maritime Dimension erfasst und zeigt sich an den Bestrebungen Neu-Delhis und Islamabads, U‑Boot-gestützte Kernwaffen zu entwickeln. Unabhängig von den jeweiligen Motivationen, die dem Aufbau dieser Systeme zugrunde liegen, werfen solche Waffen zentrale Fragen für die Stabilität zwischen Kernwaffenstaaten auf.

AbstractThe present work was carried out to study the ability of five probiotics on the in vitro degradation of Aflatoxins B1 (AFB1). The best results of in vitro were tested on the detoxification of AFB1 in rabbits. A total of 40 growing New Zealand White (NZW) male rabbits were assigned to five experimental groups. Animals were fed the following diets: basal diet (control), basal diet contaminated with 300 ppb AFB1, basal diet contaminated with 300 ppb AFB1. + probiotic 3 (0.5 g/kg diet), basal diet contaminated with 300 ppb AFB1 + ajowan (0.5 g/kg diet), and basal diet contaminated with 300 ppb AFB1 + probiotic 3 (0.5 g/kg diet) + ajowan (0.5 g/kg diet). Live body weight significantly (P < 0.05) decreased in rabbits fed AFB1 contaminated diet compared to the control rabbits. All additives improved (P < 0.05) the live body weight. The best improvement occurred with probiotics + ajowan. The addition of probiotics increased (P < 0.05) daily body weight gain in all weeks except the first week. Adding ajowan or ajowan + probiotic led to a significant (P < 0.05) increase in live body weight gain and feed intake compared to rabbits fed AFB1 alone. The digestion coefficients of dry matter (DM), organic matter (OM), crude fiber (CF), ether extract (EE), nitrogen-free extract (NFE), and digestible crude protein (DCP) significantly (P < 0.05) decreased in rabbits fed AFB1 contaminated diet. All additives improved (P < 0.05) the digestibility coefficients of DM, OM, EE, CF, NFE, and total digested nutrients (TDN)%. The best improvement occurred with probiotics + ajowan. Concentrations of serum total protein, albumin and globulin significantly (P < 0.05) decreased in rabbits fed AFB1 contaminated diet compared with the control rabbits. In conclusion, the addition of probiotic 3 (AVI-5-BAC) + ajowan could be recommended to eliminate the toxicity of AFB1 and improve growth performance criteria in rabbits.

Authors: Bonet José 
Published: September 2022

AbstractIn this survey we report about recent work on weighted Banach spaces of analytic functions on the unit disc and on the whole complex plane defined with sup-norms and operators between them. Results about the solid hull and core of these spaces and distance formulas are reviewed. Differentiation and integration operators, Cesàro and Volterra operators, weighted composition and superposition operators and Toeplitz operators on these spaces are analyzed. Boundedness, compactness, the spectrum, hypercyclicity and (uniform) mean ergodicity of these operators are considered.
Application and development of zero-valent iron (ZVI) for groundwater and wastewater treatment
Authors: Plessl K. , Russ A. , Vollprecht D. 
Published: September 2022

AbstractZero-valent iron has been used for more than 130 years for water treatment. It is based on redox reactions as well as on sorption to the corrosion products of iron. It is successfully applied for the removal of metals and organic pollutants from groundwater and wastewater. There are different variations how zero-valent iron can be used, especially (i) permeable reactive barriers, (ii) fluidized bed reactors and (iii) nanoscale zero-valent iron. Permeable reactive barriers are used for in situ treatment of groundwater in trench-like constructions or in a funnel and gate system. Their advantages are low maintenance cost, inexpensive construction and prevention of excavation wastes, and their disadvantages are surface passivation and clogging of pores by corrosion products. Zero-valent iron nanoparticles are injected directly in contaminated soil or groundwater. Their advantages are a higher reactivity than coarse-grained zero-valent iron and their mobility in the subsurface to reach the contaminated areas. However, they also have some major disadvantages like fast ageing in the system, phytotoxicity, agglomeration during migration and high costs. The latest development is a fluidized bed process (“ferrodecont process”) which avoids the passivation and clogging observed in permeable reactive barriers as well as the high costs and toxicity issues of nanoscale zero-valent iron. First results of this technology for Cr(VI) and organically contaminated groundwaters and metal removal from industrial wastewaters are highly promising.

Published: September 2022

AbstractThe hybrid manufacturing procedure of combining an initial machining process and a posterior laser powder bed fusion (LPBF) process opens a new range of possibilities for manufacturing complex parts, promising to reduce both costs and printing time. Hence, the first portion of the part might be manufactured by machining, which is used as the substrate for the LPBF. Different manufacturing processes produce a melting interface zone (MIZ) that can affect the mechanical properties of hybrid parts. This work investigates the properties of the MIZ in hybrid parts. The influence of the energy density of the LPBF process on the interface zone and the mechanical properties of the final hybrid part were assessed. The different tests showed high-quality interphase even with low energy density, with a melting depth of up to 0.3 mm. Tomography analysis showed no pores in the MIZ and the increase in pore number with the scanning speed, reducing the UTS of the hybrid samples from 8 to 42% in relation to machined Corrax®. Additionally, a test piece for injection molding was produced by this new hybrid manufacturing process. The results showed that the costs and manufacturing time were reduced by about 50%, showing a potential application of hybrid manufacturing in such applications. Besides, this work identifies a limitation of the hybrid manufacturing approach using LPBF machines which are not equipped with a system to identify the substrate coordinate system. The present study develops an operational method to identify the coordinate system in order to ease the referencing of the pre-machined substrate within the machine platform.

Published: September 2022

AbstractOne-dimensional (1D) SiO2 nanofibers (SNFs), one of the most popular inorganic nanomaterials, have aroused widespread attention because of their excellent chemical stability, as well as unique optical and thermal characteristics. Electrospinning is a straightforward and versatile method to prepare 1D SNFs with programmable structures, manageable dimensions, and modifiable properties, which hold great potential in many cutting-edge applications including aerospace, nanodevice, and energy. In this review, substantial advances in the structural design, controllable synthesis, and multifunctional applications of electrospun SNFs are highlighted. We begin with a brief introduction to the fundamental principles, available raw materials, and typical apparatus of electrospun SNFs. We then discuss the strategies for preparing SNFs with diverse structures in detail, especially stressing the newly emerging three-dimensional SiO2 nanofibrous aerogels. We continue with focus on major breakthroughs about brittleness-to-flexibility transition of SNFs and the means to achieve their mechanical reinforcement. In addition, we showcase recent applications enabled by electrospun SNFs, with particular emphasis on physical protection, health care and water treatment. In the end, we summarize this review and provide some perspectives on the future development direction of electrospun SNFs.
Filtration Efficiency in the Recycling Process of Particle-Reinforced Aluminum Alloys Using Different Filter Materials

Published: September 2022

AbstractIn this study, filtration of aluminum alloy (Al) with different weight fractions of SiC particles (SiCp) was investigated. Therefore, three different filter materials of 20 pores per inch (ppi) ceramic foam filters (CFF) were tested. A special three-chamber furan mold was used for the casting trials to provide uniform filling and flow conditions for the filtration process. Samples from sections of the gating system, as well as from the filter, were analyzed by optical light microscopy to determine the amount, size, and distribution of SiCp. A scanning electron microscope (SEM) with energy-dispersive X-ray spectroscopy (EDS) was used for obtaining the element distribution in the composite. The filtration efficiency increased by decreasing the weight fraction from 20 to 5% of SiCp and reached a significant particle reduction of over 90%. Investigations of CFFs with a weight fraction of 10% have shown a clogging effect and metal flow interruption through the 20 ppi filter. An oxide layer was detected around the respective SiCp in the EDS. Moreover, a strong accumulation effect was observed, indicated by a steadily flattening curve of the density functions after each additional remelting cycle of the same composite material.
Revisiting the islam-patriarchy nexus: is religious fundamentalism the central cultural barrier to gender equality?
Authors: Öztürk Cemal 
Published: September 2022

AbstractIs Islam a religion that promotes patriarchy? In the academic debate, there are different assessments. On the one hand, there is the thesis of an elective affinity between Islam and patriarchal values. In Muslim-majority countries and among Muslims, support for patriarchal values is most pronounced. On the other hand, there is the antithesis of Islamic feminism, which shows that a significant proportion of devout Muslims support gender equality. It is therefore wrong to describe Islam as a misogynistic religion. What matters is whether the religion is interpreted in an emancipatory manner. This contribution offers a synthesis and argues that religious fundamentalism provides a more valid explanation for patriarchal values than simplistic references to Islam. The 6th and 7th waves of the World Values Survey were analyzed to test this research-guiding hypothesis. Multilevel analyses show that value differences between Muslims and non-Muslims and between Muslim-majority societies and societies with another majority religion turn out to be small or even insignificant when controlling for religious fundamentalism. Fundamentalism is the central driver of patriarchal values and generates uniform effects. At the individual-level, fundamentalism makes both Muslims and non-Muslims more susceptible to patriarchal values. Moreover, Muslims and non-Muslims adapt to the conformity pressures of their societies, resulting in egalitarian as well as patriarchal values, depending on the prevalence of fundamentalism. The high support for patriarchal values in Muslim-majority countries has a simple reason: Religious fundamentalism is by no means a marginal phenomenon in these societies, but rather the norm.

Published: September 2022

AbstractThis paper presents a physics-based 0-D steady-state model of a radiofrequency ion thruster (RIT) that is valid for any propellant blend, and hence, any plasma mixture, and the model is used to predict the drag compensation capability and plasma composition of an air-breathing RIT operating in very-low Earth orbit (VLEO). This study fills a gap in the modeling of air-breathing electric propulsion with an air-breathing RIT model that is validated with experimental data of a RIT operating with an $${\mathrm{N}}_{2}$$

in the collector, and the model is used to calculate an air-breathing RIT’s thrust, discharge efficiency, mass utilization efficiency, and discharge plasma composition at altitudes between 80 and 150 km. At 1 kW of total input power and an optimal flow rate of 0.17 mg/s, the net thrust was limited to 3 mN at all altitudes considered. At these same operating conditions, the mass utilization efficiency and discharge efficiency were approximately 0.15 and 870 eV/ion, respectively. To increase the performance of the thruster, the magnetic field should be increased in order to increase the beam current. The mole fraction of atomic oxygen in the discharge chamber was found to be between 0.19 and 0.27 depending on the altitude, indicating that grid erosion should be a focus of future studies.
Dynamic impacts of economic growth, renewable energy use, urbanization, industrialization, tourism, agriculture, and forests on carbon emissions in Turkey
Authors: Raihan Asif , Tuspekova Almagul 
Published: September 2022

AbstractThe present study examined the dynamic effects of economic growth, renewable energy use, urbanization, industrialization, tourism, agricultural productivity, and forest area in Turkey to accomplish environmental sustainability by lowering carbon dioxide emissions. The Dynamic Ordinary Least Squares method was used to analyze time series data from 1990 to 2020. The results disclosed that a 1% rise in economic growth, urbanization, industrialization, and tourism will raise carbon dioxide emissions by 0.39%, 1.22%, 0.24%, and 0.02% in Turkey, respectively. Furthermore, a 1% increase in renewable energy consumption, agricultural productivity, and forest area might result in reductions in carbon dioxide emissions of 0.43%, 0.12%, and 3.17%, respectively. This article made policy recommendations on low-carbon economies, renewable energy use, sustainable urbanization, green industrialization, eco-friendly tourism, climate-smart agriculture, and sustainable forest management, all of which could help to accomplish environmental sustainability by lowering emissions.

Potential interactions between metal-based phenanthroline drugs and the unfolded protein response endoplasmic reticulum stress pathway
Authors: O’Leary Tadhg , McCarron Pauraic , Devereux Michael , Meaney Steve 
Published: September 2022

Abstract
The unfolded protein response has recently been implicated as a mechanism by which 1,10-phenanthroline-containing coordination compounds trigger cell death. We explored the interaction of two such compounds—one containing copper and one containing manganese—with endoplasmic reticulum (ER) stress. Pretreatment with anisomycin significantly enhanced the cytotoxic activity of both metal-based compounds in A2780, but only the copper-based compound in A549 cells. The effects of pretreatment with tunicamycin were dependent on the nature of the metal center in the compounds. In A2780 cells, the cytotoxic action of the copper compound was reduced by tunicamycin only at high concentration. In contrast, in A549 cells the efficacy of the manganese compound cells was reduced at all tested concentrations. Intriguingly, some impact of free 1,10-phenanthroline was also observed in A549 cells. These results are discussed in the context of the emerging evidence that the ER plays a role in the cytotoxic action of 1,10-phenanthroline-based compounds.

Published: September 2022

AbstractAcademic hospital nurses were surveyed to assess adherence barriers to a universal povidone-iodine nasal decolonization protocol to prevent Staphylococcus aureus infection. Low training rates, inadequate supplies, documentation and tracking challenges, patient refusal, and burnout contributed to suboptimal adherence. Prioritizing education is essential but alone is insufficient for successful protocol adoption.
EXPANDING THE REALS BY CONTINUOUS FUNCTIONS ADDS NO COMPUTATIONAL POWER

Published: September 2022

AbstractWe study the relative computational power of structures related to the ordered field of reals, specifically using the notion of generic Muchnik reducibility. We show that any expansion of the reals by a continuous function has no more computing power than the reals, answering a question of Igusa, Knight, and Schweber [7]. On the other hand, we show that there is a certain Borel expansion of the reals that is strictly more powerful than the reals and such that any Borel quotient of the reals reduces to it.
The civic district of Sala (Chellah – Rabat, Morocco): shaping and perceiving monuments under the Roman Empire
Authors: Camporeale Stefano , Mugnai Niccolò , Pansini Rossella 
Published: September 2022

AbstractThis article investigates the development of urbanism and architecture at the site of Sala (Chellah), from the end of the first century BC to the latter half of the second century AD. By looking at the transformations in the town's civic centre from the Mauretanian to Roman imperial period, the aim is to assess how the layout and function of public spaces and buildings were reshaped to respond to new ideas of monumentality. A range of research methodologies are applied to address this question, including architectural, archival, and archaeological analyses, as well as the use of 3D digital modelling. The case study of Sala is of particular importance, as it shows how certain pre-Roman monuments were kept in use within new public contexts, and how imperial-style, urban and architectural features were introduced in the town as part of trends that can be recognized across North Africa and the Roman Empire more broadly.
Partisanship in times of crisis: evidence from Italy
Authors: Bankert Alexa , Del Ponte Alessandro , Huddy Leonie 
Published: September 2022

AbstractThere is a continuing debate over the political importance and durability of partisan attachments in European multi-party systems. Drawing on a nationally representative five-wave panel, we provide a longitudinal test of the power of partisanship in Italy over the course of the tumultuous 2013 national elections. We find that a strong partisan affiliation measured as a social identity two years prior to the election promoted system stability by increasing support for the in-party and inhibiting electoral support for the insurgent Five Star Movement (M5S). In contrast, non-partisans, especially highly educated ones, were more likely than partisans to vote for M5S. Our results illustrate the role of partisanship in stabilizing multi-party systems amid crisis.
