Educating and hiring an “African” in America’s Colleges/Schools of Education: my voice
Authors: Obiakor Festus E. 
Published: April 2022

Abstract
Africans coming to the United States of America to go to school traditionally have the ultimate goal of getting the best education and going back to their respective countries. That was my goal when I left Nigeria many decades ago! However, considering the socio-economic and political upheavals in African nations, one is forced to rethink the goal, especially when your family arrives at the same uneasy and difficult conclusion. Leaving family members is bad enough, and not going back after one’s education is even worse. These are the psychological battles that most Africans endure when they decide to finally settle to work in the United States. Then, when one combines these family worries with searching for jobs; locating jobs; enduring departmental, College/School, and university politics; and marrying and raising families; the problems become unbearable and frequently insurmountable. The consequences are grave and require well-planned survival skills that are unimaginable. This is my story and the essence of this article.
Anomalous resonance frequency shift in liquid crystal-loaded THz metamaterials

Published: April 2022

Abstract
Babinet complementary patterns of a spectrally tunable metamaterial incorporating a nematic liquid crystal is normally assumed to exhibit the same tuning range. Here we show that for a hybrid, liquid crystal-loaded metamaterial, the sensitivity of its terahertz resonances to the variations of the refractive index differs substantially for the two complementary patterns. This is due to a mismatch between the alignment of the liquid crystal and the direction of the local electric field induced in the metamaterial patterns. Furthermore, and more intriguingly, our experimental data indicate that it is possible to shift the resonance of the positive metamaterial pattern beyond the limit imposed by the alignment mismatch. Our analysis suggests that the observed anomalous frequency shift results from the orientational optical nonlinearity of a nematic liquid crystal.

Published: April 2022

Abstract
Inorganic ion-exchange materials show potential application for toxic radioactive ions due to their remarkable high efficiency and selectivity features. Here, two type of carbon-supported titanate (C@TNFs and C@TNFs(H)) nanofibers have been synthesized by a cost-effective in suit growth method. The resulting C@TNFs and C@TNFs(H) microspheres present uniform flower-like morphology and large surface area. The interlayer Na+ in the titanate shell provides docking sites for ion-exchange of radioactive ions (U(VI), Ba(II), and Sr(II)). Interestingly, the exceeding theoretical cation-exchange capacities (CECs) are achieved on C@TNFs for U(VI) ∼4.76 meq g−1 and Ba(II) ∼2.65 meq g−1 and C@TNFs(H) for Ba(II) ∼2.53 meq g−1 and Sr(II) ∼2.24 meq g−1, respectively. The impressive adsorption performance is mainly attributed to the synergistic effects of ion-exchange and surface complexation. More significantly, C@TNFs and C@TNFs(H) maintain high distribution coefficients (K
d
U) of >104 mL g−1 over a wider pH range (pH = 3.5–9.0) and high adsorption rate with short equilibrium time within 50 min. Competitive ion-exchange investigation shows a selectivity order of U(VI) > Ba(II) > Sr(II) at individual 10 ppm concentration, pH = 6.0 and T = 298 K. The related spectroscopic studies reveal the intercalative mechanism of radionuclides in the deformed titanate structure, as a result of target ions firmly trapped in the interlayer of C@TNFs and C@TNFs(H). These advantageous features allow the C@TNFs and C@TNFs(H) to be promising candidates for the remediation of toxic radioactive ions polluted water.
The speciation of protactinium since its discovery: a nightmare or a path of resilience
Authors: Le Naour Claire , Maloubier Melody , Aupiais Jean 
Published: April 2022

AbstractThis review concerns the speciation of protactinium in aqueous solution under its both oxidation states +IV and +V. Emphasis is placed on experimental data obtained at trace level but also in macroscopic amount leading to the determination of thermodynamic and structural data. Thus, the complexation of Pa(V) with mineral acids and organic acids, mainly polyaminocarboxylic acids (iminodiacetic acid [IDA], nitrilotriacetic acid [NTA], ethylenediaminetetraacetic acid [EDTA] and diethylenetriaminepentaacetic acid [DTPA]) are highlighted and compared. The review also includes the actual knowledge about the Pa(IV) aqueous chemistry pinpointing its spectroscopic features.
Industrial emissions effect into atmospheric air quality: mathematical modeling
Authors: Lukyanets Artem , Gura Dmitry , Savinova Olga , Kondratenko Larisa , Lushkov Richard 
Published: April 2022

Abstract
This paper presents the results of modeling the distribution process of industrial emission components at specified distances from the emission source along the normal. The model uses a system of differential diffusion equations to compute the concentration profiles of aerosols, industrial gases, and fine particles in the atmosphere. In order to investigate the regularity of the emitter propagation into the atmosphere, a theory of impurity dispersion was developed. The model is constrained by the effect of particle interactions. The partial derivative equations are presented to calculate the concentrations of aerosols and fine particles under the turbulent airflow in the atmosphere, dispersion of inert impurities, and distribution of chemically active compounds. The adequacy of the mathematical model for a series of theoretical calculations was checked by contrasting the data of the atmospheric air monitoring for the cities of Almaty, Ust-Kamenogorsk, Pavlodar, Atyrau, Krasnodar, Chelyabinsk, Beijing, and Shanghai. Air monitoring data included PM10, SO2, and NO2 levels. The mathematical model solutions for the relative values of the emitter concentration in the direction along the normal of the pollution source at the surface were obtained. Graphical interpretation of the calculation results over the 0…200 m distance for time intervals ranging from 3 to 600 min was provided. According to the multiple factor cluster analysis, the critical values of SO2 concentrations in Atyrau exceeded MPC in 26.2% of cases. The level of NO2 for Shanghai was 15.6%, and those for PM10 concentrations in Almaty and Atyrau amounted to 16.4%. A comparison of theoretical values and results obtained from official sources showed arithmetic mean of 49.4 mg/m3 and maximum value of 823.0 mg/m3. Standard deviation comprised 48.9 mg/m3. Results were considered statistically significant at p≤0.005. The mathematical model developed in this study can be used to predict the status of atmospheric air.
Service Dominant Logic and Market Orientation: A Case Study of Brazilian Agribusiness Firms
Authors: Albuquerque Mariangela Duarte Soares , Martins Tomas Sparano 
Published: April 2022

Abstract
The purpose of this paper is to evaluate the Service Dominant Orientation (S-DO), Responsive Market Orientation (RMO) and Proactive Market Orientation (PMO) complementary effect on Brand Performance in the Brazilian agribusiness B2B context. We conducted a survey with 147 Brazilian agribusiness firms that sell supplies directly to farmers. The data were analysed through a three-model hierarchical regression analysis. The results indicated that S-DO complemented by PMO and RMO impacts and explains brand performance at more significant levels than S-DO by itself. The complementary effect is highlighted when firms give voice and partner up with their customers that leads the proactively innovative research based on their latent needs. The study allows agribusiness marketing managers to reflect on the insertion of the B2B customer in the firm’s value co-creation process through a guided innovative research process.
Story versus discourse in film studies: a return to the theory of enunciation
Authors: González-Requena Jesús , Casanova Basilio 
Published: April 2022

Abstract
In this paper, we address the problematic of film narration and its narrator from a re-reading of Émile Benveniste’s theory of enunciation in open discussion with both the theories of film enunciation that have derived from it, and the cognitive theories that, by discarding it, have tried to take its place. This has led us to a differentiation between two dimensions of the problem of enunciation that are usually ignored: that which separates the act of enunciation and the subject who performs it from that of the textual subjects (the enunciator, the narrator …) who inscribe that act in the text. An erroneous understanding of the modes of enunciation of story and discourse has derived from their ignorance, which has led to reducing the former to a kind of form that derives from the latter, constituting no more than a form of discourse that would hide its basis. A precise enunciative definition of the lie is derived from their conscience. Certainly, there is always a subject of the act of enunciation whose traces can be recognized in the materiality of the statement. But there is a properly ontological distance that separates them – as material traces – from the enunciator, as a purely formal textual figure that, by being that, may or may not be present in the text. In this way, the Benveniste’s affirmation can be sustained according to which the story, the pure mode of the narrative, so to speak, is characterized by the absence – not the erasure, nor the invisibility – of any enunciator.
Classification and Medical Applications of Biomaterials–A Mini Review
Authors: Chong Eric Tzyy Jiann , Ng Jun Wei , Lee Ping-Chin 
Published: April 2022

Abstract
Biomaterials are natural, synthetic, or hybrid materials, which are used in medical devices or implants that are placed in contact with the human biological system to compensate for or restore diminished functions of the body. The field of biomaterials has rapidly developed to meet the ever-expanding needs in healthcare and medicine practices. Advancements in science and technology have enabled the fabrication and reengineering of biomaterials into useful medical devices or implants, such as heart valves, bone plates, hip joints, and cardiac pacemakers. Because biomaterials are placed in continuous close contact with the recipient’s body fluids or tissues, the classification of available biomaterials is crucial for selecting safer and highly biocompatible materials. This review focuses on biomaterial classification, namely bioceramic, polymeric, and metallic biomaterials. Their medical applications, advantages, and disadvantages are discussed. Current trends in biomaterials involved in disease treatments, such as controlled drug delivery and cancer therapy, are additionally explored.
International comparison of variation in performance between hospitals for THA and TKA: Is it even possible? A systematic review including 33 studies and 8 arthroplasty register reports

Published: April 2022

In order to improve care for total hip and knee arthroplasties (THA/TKA), hospitals may want to compare their performance with hospitals in other countries. Pooling data across countries also enable early detection of infrequently occurring safety issues. We therefore aimed to assess the between-hospital variation and definitions used for revision, readmission, and complications across countries.
PubMed, Embase, Web of Science, Cochrane library, Emcare, and Academic Search Premier were searched from January 2009 to August 2020 for studies reporting on: (i) primary THA/TKA; (ii) revision, readmission, or complications; and (iii) between-hospital variation. Most recent registry reports of Network of Orthopedic Registries of Europe members were also reviewed. Two reviewers independently screened records, extracted data, and assessed the risk of bias using the Integrated quality Criteria for the Review Of Multiple Study designs tool for studies and relevant domains for registries. We assessed agreement for the following domains: (i) outcome definition; (ii) follow-up and starting point; (iii) case-mix adjustment; and (iv) type of patients and hospitals included.
Between-hospital variation was reported in 33 (1 high-quality, 13 moderate-quality, and 19 low-quality) studies and 8 registry reports. The range of variation for revision was 0–33% for THA and 0–27% for TKA varying between assessment within hospital admission until 10 years of follow-up; for readmission, 0–40% and 0–32% for THA and TKA, respectively; and for complications, 0–75% and 0–50% for THA and TKA, respectively. Indicator definitions and methodological variables varied considerably across domains.
The large heterogeneity in definitions and methods used likely explains the considerable variation in between-hospital variation reported for revision, readmission, and complications , making it impossible to benchmark hospitals across countries or pool data for earlier detection of safety issues. It is necessary to collaborate internationally and strive for more uniformity in indicator definitions and methods in order to achieve reliable international benchmarking in the future.
The 2021 Pediatric Hospital Medicine Workforce: Results of a National Survey of Program Leaders
Authors: Fromme H. Barrett , Ruch-Ross Holly S. , Marks Michelle , Barone Lauren , Shaugnessy Erin 
Published: April 2022

OBJECTIVE
Pediatric Hospital Medicine (PHM) is a young subspecialty with practice models that continue to evolve. To inform program and workforce planning, it is essential to understand the current state. This study sought to delineate current work models for PHM.

METHODS
In the spring of 2021, we conducted a survey-based cohort study of individuals identifying as PHM program leaders. Individuals were invited based on membership in the 3 PHM sponsoring societies. Additional respondents were recruited through society listservs.

RESULTS
One hundred ninety-eight program leaders responded to the program model survey. One-half covered only community sites, 21.2% covered only university sites, and 21.2% covered both university and community sites. Programs provided a diverse set of services, with community sites covering more services, including newborn nurseries, emergency department consultation, and delivery room care. Median total hours for 1.0 clinical full time equivalent were 1849 across all sites, 1800 at university-only sites, and 1900 at community-only sites. Inpatient floor patient caps, when present, were higher for resident covered versus noncovered teams (16 vs 13). Similarly, back-up activation was higher for resident-covered teams (15–16) than noncovered teams (12–13.5).

CONCLUSIONS
Current data on clinical work hours for pediatric hospitalists are consistent with recent, smaller studies, suggesting that the current national median for a 1.0 FTE clinical position at university-based sites is 1800 annual hours. Community hospitalists often work more clinical hours than university sites and more commonly provide a broader range of service lines. More studies are needed to explore the differences between community and university site work models.

Published: April 2022

AbstractIn this work, the properties of mechanochemically produced (by using mills made from different materials) barium-titanate (BaTiO3) and zinc-titanate (ZnTiO3) perovskites are compared. Mechanochemistry is a process that can cover the energy demand of some reaction pathways between solid materials. This process is called “high-energy milling”, for which not all types of mills are suitable. In our case, a planetary ball mill provided the necessary energy. Using a model, the required energy is determinable; the energy released during an impact of a milling ball (Eb – ball-impact energy), as well as during the whole milling (Ecum – cumulative milling energy). Thus, a milling-energy map was created, with which the applied Eb and Ecum values were visualized depending on the different grinding parameters. The parameters changed were the material of the grinding vessels, the number of grinding balls, and the rotational speed. The transformation was tracked by X-ray diffraction (XRD) measurements, and electron microscopic images (TEM and SEM) of the perovskites produced were taken. This study aimed to draw conclusions that will help later in the synthesis of materials with other perovskite structures by choosing optimal milling parameters.

Effect of ‘loss of function’ mutation in <i> SER1 </i> in wine yeast: fermentation outcomes in co-inoculation with non-<i>Saccharomyces </i>
Authors: Lang Tom A. , Walker Michelle E. , Boss Paul K. , Jiranek Vladimir 
Published: April 2022

In wine fermentation, improved wine complexity and sensorial properties can arise from the use of non-Saccharomyces yeast. Generally less alcohol tolerant, such strains often do not finish fermentation, therefore requiring a second inoculation with the more robust Saccharomyces cerevisiae, usually added on Day 3. This sequential approach affords non-Saccharomyces time to make an impact before being overtaken by S. cerevisiae. However, two inoculations are inconvenient; therefore the identification of a slow growing S. cerevisiae strain that can be used in a single co-inoculation with the non-Saccharomyces yeast is highly attractive. In this study we investigated the use of the naturally occurring ‘loss of function’ SER1 variant, identified in a Sake yeast, for the purposes of carrying out co-inoculated wine fermentations. The SER1-232(G > C; G78R) change was introduced into the commonly used wine strain, EC1118, via CRISPR/Cas9 editing. In a chemically defined grape juice medium, the SER1(G78R) mutant grew and fermented more slowly and increased acetic acid, succinic acid and glycerol concentrations. Simultaneous inoculation with the slower-growing mutant with a Metschnikowia pulcherrima or Lachancea thermotolerans strain in sterile Sauvignon blanc juice resulted in differences in sensorial compounds, most likely derived from the presence of non-Saccharomyces yeasts. The EC1118 SER1 (G78R) mutant completed fermentation with M. pulcherrima, MP2, and in fact improved the viability of MP2 compared to when it was used as a monoculture. The SER1 (G78R) mutant also promoted both the growth of the SO2-sensitive L. thermotolerans strain, Viniflora® Concerto™, in a juice high in SO2 and its subsequent dominance during fermentation. In co-fermentations with wild-type EC1118, the Concerto™ population was substantially reduced with no significant changes in wine properties. This research adds to our understanding of the use of a novel slow-growing S. cerevisiae yeast in wine fermentations co-inoculated with non-Saccharomyces strains.
