Authors: Dhote Yash , Altay Bilge Nazli , Myers Bruce L. , Telhan Refik 
Published: December 2023

AbstractAccurately assessing the color quality of printed products becomes intricate when optical brightening agents (OBAs) are introduced in papers, as diverse interactions occur among different ink pigments and papers containing OBAs due to variations in ink formulation chemistries. Specifically, alkali‐based pigments, commonly used as spot colors, are carefully formulated to ensure consistency across production batches. The presence of OBAs, which absorb ultraviolet light and emit it in the visible spectrum, significantly affects color perception and accuracy on paper when interacting with these inks. This research marks an initial investigation into how OBAs in paper influence the color accuracy of five distinct alkali‐based spot color paste inks using a Little Joe ink proofer. The research examines the physical, optical, and colorimetric characteristics of two paper samples‐one with OBA and one without‐ and analyzes the colorimetric changes occurring during the ink drying process. The results indicate that reflex blue, purple, and violet spot colors achieved acceptable delta E (ΔE00) value of below 3 on non‐OBA paper, with rubine red being on the borderline at 3.1 after 48 h. In contrast, purple, rhodamine red and violet achieved acceptable ΔE00 below 3 on high OBA paper. The distinct behavior exhibited by certain inks led to the conclusion that achieving a consistent proofing procedure across diverse alkali‐based ink formulations is impractical.

AbstractA comprehensive investigation is conducted on the electronic structure and magnetic properties of half‐Heusler NaScGe, which is doped with a rare earth element Nd with different concentrations. The Heusler Na1‐xNdxScGe (where x = 0, 0.25, 0.75, and 1) compounds are thoroughly investigated. The examination encompassed structural, elastic, magnetic, and electronic characteristics using the full potential linearized augmented plane wave (FP‐LAPW) method. Generalized gradient approximation (GGA) is used to calculate the structural parameters and electronic characteristics. The equilibrium lattice constant and band gap of half‐Heusler NaScGe are found to be in good accord with other data. The density of states (DOS) investigation has revealed a semiconductor behavior of half‐Heusler NaScGe and half‐metallic ferromagnetic properties of quaternary‐Heusler Na0.75Nd0.25ScGe, characterized by a moderate band gap in minority spin channel. In addition, the DOS analysis has shown that both ternary half‐Heusler NdScGe and QH Na0.25Nd0.75ScGe compounds have exhibited metallic ferromagnetic activity. The work has introduced a novel approach for producing half metals from the semiconductor half‐Heusler NaScGe. Quaternary‐Heusler Na0.75Nd0.25ScGe is identified as a promising material for applications spintronic.

Published: December 2023

AbstractThe synthesis of P‐stereogenic phosphorus compounds has gained considerable attention due to their wide applications across many research fields. Among the available strategies, transition metal‐catalyzed asymmetric transformation of pentavalent phosphoryl (H−P(O)) precursors is particularly appealing. This approach involves a direct C−P bond‐forming process, rendering it straightforward, and it employs readily available, bench‐stable H−P(O) reagents that are compatible with various metal catalysts. Recent years have witnessed significant progress in this field, with a primary focus on asymmetric C−P cross‐couplings and hydrophosphorylations. This Concept article provides a brief summary of recent progress, highlights existing challenges, and discusses future directions in this exciting area.
Some issues in the practical application of risk‐targeted ground motions
Authors: Baltzopoulos Georgios , Grella Antonio , Iervolino Iunio 
Published: December 2023

AbstractRisk‐targeted spectra for seismic design have been proposed in earthquake engineering literature to harmonize seismic reliability for different structures designed at different sites. Such a proposal has been motivated by the fact that designing for uniform seismic hazard across building sites has been shown to generally lead to non‐uniform seismic risk. This note uses a case study implementation of the risk‐targeted design actions philosophy for seven Italian sites, to showcase two noteworthy practical issues with this otherwise appealing approach. First, at lower‐to‐moderate‐hazard sites, which may be the majority in a country, design against gravity loads and detailing according to minimum code requirements, can result in higher‐than‐anticipated overstrength, not commensurate with the adopted level of seismic design loads, thus deviating from the target reliability. This leaves only higher‐hazard sites with real margins for homogenization of reliability, which raises the bar. Second, risk‐targeted spectrum approaches typically require some a‐priori assumptions for structural fragility at low‐performance objectives, corresponding to alleged high damage. These assumptions, among others, carry an implicit adoption of shaking intensity measures with which to express fragility, whose lack of sufficiency and efficiency may in turn reduce the level of homogenization of risk that can be achieved.

AbstractThe yield and properties of banana juice extracted by enzymatic pretreatments using different enzymes and were compared among themselves and with hot water extraction. The treatments that gave higher yield and better properties of the juices were used for winemaking and the properties of the wines were also compared. A comparison of gas chromatography‐mass spectrometry analysis was also done between the juices and the wines. The various treatments were hot water bath extraction and different enzymes (amylase, cellulase, pectinase, and viscozyme) at two concentrations (0.05% and 0.1%). Juice yield, total soluble sugars, pH, titrable acidity, reducing sugars, and transmittance were analyzed. Best results for juice recovery (46.44 ± 0.50%), total soluble solids (14.8 ± 0.01 °Brix), and transmittance (86.93 ± 2.68%) were achieved using pectinase (0.1%), while viscozyme (0.1%) yielded best results for viscosity (1.49 ± 0.09 mPa.s), pH (5.01 ± 0.05), and acidity (0.277 ± 0.01%). The banana juices from these treatments were then used for wine preparation, and the physicochemical parameters were monitored during a 30‐day storage period. Within 20 days during fermentation, a reduction in total soluble solids from 22 °Brix to 6.1 °Brix was observed. Juice from banana pulp can be successfully extracted using the enzymes pectinase and viscozyme, and wine can be prepared from the enzymatically extracted juices.

Published: December 2023

AbstractInhospitable, inaccessible, and extremely remote alike the famed pole of inaccessibility, aka Point Nemo, the isolated locations in deserts, at sea, or in outer space are difficult for humans to settle, let alone to thrive in. Yet, they present a unique set of opportunities for science, economy, and geopolitics that are difficult to ignore. One of the critical challenges for settlers is the stable supply of energy both to sustain a reasonable quality of life, as well as to take advantage of the local opportunities presented by the remote environment, e.g., abundance of a particular resource. The possible solutions to this challenge are heavily constrained by the difficulty and prohibitive cost of transportation to and from such a habitat (e.g., a lunar or Martian base). In this essay, the advantages and possible challenges of integrating Fischer–Tropsch, artificial photosynthesis, and plasma catalysis into a robust, scalable, and efficient self‐contained system for energy harvesting, storage, and utilization are explored.

Published: December 2023

AbstractNonalcoholic fatty liver disease (NAFLD) is a global public health problem that affects more than a quarter of the population. The development of this disease is correlated with metabolic dysfunctions that lead to lipid accumulation in the liver. Pesticides are one of etiologies that support NAFLD establishment. Therefore, the effects of the insecticide fipronil on the lipid metabolism of the human hepatic cell line, HepG2, was investigated, considering its widespread use in field crops and even to control domestic pests. To address the goals of the study, biochemical, cellular, and molecular analyses of different concentrations of fipronil in cell cultures were investigated, after 24 h of incubation. Relevant metabolites such as triglycerides, glucose levels, β‐oxidation processes, and gene expression of relevant elements correlated with lipid and metabolism of xenobiotics were investigated. The results suggested that at 20 μM, the pesticide increased the accumulation of triglycerides and neutral lipids by reducing fatty acid oxidation and increasing de novo lipogenesis. In addition, changes were observed in genes that control oxidative stress and the xenobiotic metabolism. Together, the results suggest that the metabolic changes caused by the insecticide fipronil may be deleterious if persistent, favoring the establishment of hepatic steatosis.

AbstractLamotrigine (LTG) is an antiepileptic drug with possible adverse effects on the female reproductive system. Curcumin was declared to improve ovarian performance. Therefore, this study aimed to clarify ovulatory dysfunction (OD) associated with LTG and the role of curcumin in ameliorating this dysfunction. Adult female Wister albino rats were assigned into four groups: negative control (received saline), positive control (received curcumin only), LTG, and LTG with curcumin groups. Drugs were administered for 90 days. The hormonal profile, including testosterone, estrogen, progesterone, luteinizing hormone, and follicle‐stimulating hormone, in addition to the lipid profile and glycemic analysis, were tested. Oxidative stress biomarkers analysis in the ovaries and uterus and peroxisome proliferator‐activated receptor‐γ (PPAR‐γ) gene expression were also included. Histopathological examination of ovarian and uterine tissues and immunohistochemical studies were also performed. Curcumin could improve the OD related to chronic LTG intake. That was proved by the normalization of the hormonal profile, glycemic control, lipidemic status, oxidative stress markers, and PPAR‐γ gene expression. The histopathological and immunohistochemical examination of ovarian and uterine tissues revealed an improvement after curcumin administration. The results describe an obvious deterioration in ovarian performance with LTG through the effect on lipidemic status, PPAR‐γ gene, and creating an oxidative stress condition in the ovaries of chronic users, with a prominent improvement with curcumin addition to the treatment protocol.

AbstractThe aim of this study was to investigate the production, stability and applicability of colorants produced by filamentous fungi isolated from soil samples from the Amazon. Initially, the isolates were evaluated in a screening for the production of colorants. The influences of cultivation and nutritional conditions on the production of colorants by fungal isolates were investigated. The colorants produced by selected fungal isolates were chemically characterized using the Liquid Chromatography‐Mass Spectrometry technique. The antimicrobial and cytotoxic activities, stability evaluation and applicability of the colorants were investigated. As results, we observed that the isolates Penicillium sclerotiorum P3SO224, Clonostachys rosea P2SO329 and Penicillium gravinicasei P3SO332 stood out since they produced the most intense colorants. Compounds produced by Penicillium sclerotiorum P3SO224 and Clonostachys rosea P2SO329 were identified as sclerotiorin and penicillic acid. The colorant fraction (EtOAc) produced by these species has antimicrobial activity, stability at temperature and at different pHs, stability when exposure to light and UV, and when exposed to different concentrations of salts, as well as being nontoxic and having the ability to dye fabrics and be used as a pigment in creams and soap. Considering the results found in this study, it was concluded that fungi from the soil in the Amazon have the potential to produce colorants with applications in the textile and pharmaceutical industries.

AbstractAmidst the continual volatility in the labor market and heightened uncertainty about the future, it is imperative for students to be confident in their employability skills to navigate their careers seamlessly. Self‐perceived employability (SPE) instills in students the confidence needed to pursue their desired career paths, showcase resilience, and effectively market themselves to employers in an ever‐changing business environment. In this paper, we present a comprehensive and systematic review of the existing literature, synthesizing the insights from 88 relevant articles in Web of Science Social Science Citation Index (SSCI) through a structured framework that delineates the key antecedents, decisions, and outcomes related to SPE. This framework also encompasses underlying theories, contexts, and methodologies of study. While we highlight a plethora of research gaps, the most glaring is the inadequate conceptual development. Current theoretical approaches often lack a student‐focused perspective, sidelining critical modern viewpoints that could deepen our understanding of SPE. We advocate for richer operational definitions and introduce a blueprint of dimensions poised to nurture the evolution of such metrics. Additionally, we propose sophisticated methods to elevate the empirical exploration of the construct, ensuring a rigorous foundation for upcoming research. We further discuss potential antecedents, outcomes, and contexts, offering them as focal points for future investigative pursuits. Ultimately, our research offers invaluable insights to higher education professionals, illuminating strategies to bolster employability confidence in students, ensuring they are fully prepared for the workforce.
Analysis of changes in volatile compounds and evolution in free fatty acids, free amino acids, nucleotides, and microbial diversity in tilapia (Oreochromis mossambicus) fillets during cold storage
Authors: Cheng Hao , Mei Jun , Xie Jing 
Published: December 2023

AbstractBACKGROUNDAquatic products are rich in nutrients and unique in flavor, and are popular among the public. However, aquatic products are extremely susceptible to quality degradation during storage, of which odor deterioration is the most obvious and influential aspect. Odor deterioration in aquatic products is widespread and severely affects overall flavor and quality. In this study, odor deterioration and flavor‐related quality degradation of tilapia during cold storage are discussed, focusing on the changes in volatile compounds and the evolution of free fatty acids (FFAs), free amino acids (FAAs), nucleotides, and microbial diversity.RESULTSA total of 63 volatile compounds were detected by gas chromatography–mass spectrometry, including 11 hydrocarbons, 10 alcohols, 6 aldehydes, 8 ketones, 6 esters, 9 aromatics, 3 phenols, and 10 other compounds. Microbial diversity analysis revealed that Acinetobacter, Psychrobacter, Vagococcus, and Myroides were the main dominant species of tilapia at the end of cold storage and predicted that microorganisms could influence the flavor of tilapia by participating in important metabolic pathways. Meanwhile, the evolution of FFAs, FAAs, and nucleotides also had a significant impact on odor deterioration, as evidenced by the contribution of unsaturated fatty acids (such as oleic acid and linoleic acid), Lys, and off‐flavor nucleotides (HxR and Hx) to the undesirable flavor. Oxidation of oleic acid and linoleic acid resulted in changes in aldehydes, with Lys, HxR, and Hx being key flavor precursors and off‐flavor contributors.CONCLUSIONThis study contributes to a comprehensive overview of odor deterioration and the evolution of flavor‐related quality in tilapia during cold storage, providing new insights into the regulation of overall flavor and quality. © 2023 Society of Chemical Industry.

ObjectivesThe number and distribution of lung ultrasound (LUS) imaging artifacts termed B‐lines correlate with the presence of acute lung disease such as infection, acute respiratory distress syndrome (ARDS), and pulmonary edema. Detection and interpretation of B‐lines require dedicated training and is machine and operator‐dependent. The goal of this study was to identify radio frequency (RF) signal features associated with B‐lines in a cohort of patients with cardiogenic pulmonary edema. A quantitative signal indicator could then be used in a single‐element, non‐imaging, wearable, automated lung ultrasound sensor (LUSS) for continuous hands‐free monitoring of lung fluid.MethodsIn this prospective study a 10‐zone LUS exam was performed in 16 participants, including 12 patients admitted with acute cardiogenic pulmonary edema (mean age 60 ± 12 years) and 4 healthy controls (mean age 44 ± 21). Overall,160 individual LUS video clips were recorded. The LUS exams were performed with a phased array probe driven by an open‐platform ultrasound system with simultaneous RF signal collection. RF data were analyzed offline for candidate B‐line indicators based on signal amplitude, temporal variability, and frequency spectrum; blinded independent review of LUS images for the presence or absence of B‐lines served as ground truth. Predictive performance of the signal indicators was determined with receiving operator characteristic (ROC) analysis with k‐fold cross‐validation.ResultsTwo RF signal features—temporal variability of signal amplitude at large depths and at the pleural line—were strongly associated with B‐line presence. The sensitivity and specificity of a combinatorial indicator were 93.2 and 58.5%, respectively, with cross‐validated area under the ROC curve (AUC) of 0.91 (95% CI = 0.80–0.94).ConclusionA combinatorial signal indicator for use with single‐element non‐imaging LUSS was developed to facilitate continuous monitoring of lung fluid in patients with respiratory illness.

AbstractMicroorganisms play important roles in soil biogeochemical processes, but the relative contributions of different microbial members in soil nutrient cycling and community maintenance are unclear especially in wetland soils with water‐level fluctuation. Here, soil samples, collected from severe inundation zone (SIZ), wet–dry cycling zone (WIZ), and arid zone (NIZ) of the lakeshore wetland of plateau lake Caohai, were used to investigate the relative contributions of core and rare taxa in maintaining nutrient cycling and their associations with microbial network. Results showed that WIZ exhibited higher extracellular enzyme activities including β‐1,4‐N‐acetylglucosaminidase, L‐leucine aminopeptidase, and acid phosphatase, the level of multi‐nutrient cycling and core microbial diversity compared with the NIZ and SIZ. The values of topological features (i.e., links, average degree, clustering coefficient, and graph density) were also higher in the WIZ compared with the NIZ and SIZ. Moreover, the core taxa, specifically their community structures, were the most important driver for multi‐nutrient cycles of wetland soil. Among these taxa,Sphingomonas,Bradyrhizobium,Mortierella, andFusariumas the most abundant taxa in lakeshore wetlands were significantly positively correlated with most extracellular enzymes. By contrast, rare taxa showed higher degree and its subnetwork complexity than those of core taxa, which potentially serve as the species pool of core taxa to maintaining the microbial community stability. In conclusion, our study suggested that core taxa play dominant roles in soil nutrient cycles, while rare microbiota could greatly influence microbial interaction under hydrological changes.
