Abstract

Objectives
Analytical validation of automated erythrocyte sedimentation rate (ESR) analyzers is necessary prior to their implementation into routine practice. Our aim was to perform the analytical validation of the modified Westergren method applied on the CUBE 30 touch analyzer (Diesse, Siena, Italy).

Methods
Validation included determination of within-run and between-run precision following the Clinical and Laboratory Standards Institute EP15-A3 protocol, comparison with the reference Westergren method, sample stability assessment at both room temperature and 4 °C, after 4, 8 and 24-h storage, and checking the extent of hemolysis and lipemia interference.

Results
Coefficients of variation (CVs) for within-run precision were 5.2% for the normal and 2.6% for the abnormal range, while between-run CVs were 9.4 and 2.2%, respectively. Comparison with the Westergren method (n=191) yielded Spearman’s correlation coefficient of 0.93, no constant nor proportional difference [y=0.4 (95% CI: −1.7–1.0) + 1.06 (95% CI: 1.00–1.14)x] and a non-significant mean absolute bias of −2.6 mm (95% CI: −5.3–0.2). Lower comparability was evidenced with increasing ESR values, with both constant and proportional differences for ESR values between 40 and 80 mm, and above 80 mm. Sample stability was not compromised up to 8-h storage both at room temperature (p=0.054) and 4 °C (p=0.421). Hemolysis did not affect ESR measurement up to 1.0 g/L of free hemoglobin (p=0.089), while lipemia index above 5.0 g/L affects the ESR result (p=0.004).

Conclusions
This study proved that CUBE 30 touch provides reliable ESR measurement and satisfactory comparability with the reference Westergren methods, with minor variation related to methodological differences.

Published: February 2023

Abstract
Felodipine (FEL)–tetracyanoethylene (TCNE)–2,2′-bipyridine (Bpy) complex was prepared with FEL, TCNE–Bpy and characterized by fluorescence, ultraviolet, and infrared. By exploring the concentration and dosage of Bpy, it was found that 1 mL 2 × 10−3 mol‧L−1 of Bpy had the best effect. The sequence of reagent addition was determined to be followed by FEL, then by TCNE, and then followed by Bpy. The concentration of FEL was 2.5 × 10−4 to 9.0 × 10−3 mol‧L−1, which had a good linear relationship with fluorescence intensity. The compound had good accuracy, precision, and specificity, and could be used for the determination of phelodipine content in FEL sustained-release tablets.

Abstract
Reduced graphene oxide/maghemite (RGO/γ-Fe2O3) material was successfully synthesized by combining the modified Hummers method with co-precipitation (RGO 10 wt.%). γ-Fe2O3 nanoparticles with a particle size of ∼14.8 nm were distributed on the surface of RGO sheets. Results of Brunauer–Emmett–Teller analysis showed that RGO/γ-Fe2O3 had a mesoporous structure and a narrow capillary size distribution curve at about 13 nm. The specific surface area of the RGO/γ-Fe2O3 was 168 m2·g−1. The RGO/γ-Fe2O3 nanocomposite was used to adsorb arsenic As(V) and a mixture of heavy metals (As(V), Cr(VI), Pb(II), and Fe(III)) in water. The maximum adsorption efficiency of As(V) reached 98.9% after 45 min with an adsorption capacity of 5.93 mg·g−1, higher than the simultaneous adsorption of the four metal ions. Competitive adsorption decreased in the order As(V), Cr(VI), Pb(II), and Fe(III). Therefore, RGO/γ-Fe2O3 could be used as an effective adsorbent to remove heavy metals from aqueous solutions.
Linear mode conversion of terahertz radiation into terahertz surface plasmon wave over a graphene-free space interface
Authors: Srivastav Rohit Kumar , Panwar Anuraj 
Published: February 2023

Abstract
We analyzed the linear mode conversion of incident terahertz (THz) radiation into THz surface plasmon waves (SPWs) over a surface of graphene deposited on the rippled dielectric substrate. Obliquely incident p-polarized laser light imparts oscillatory velocity to the electrons in ripple layer regime. Electron oscillatory velocity beats with ripple surface density to produce a linear current density. We examine the tunable response of mode conversion of incident terahertz radiation with respect to change in Fermi energy of graphene and incident angle. A suitable surface ripple wave number resonantly drives the THz SPW. We observe the THz SPW generation tunability with respect to Fermi energy of graphene and incident angle. The amplitude of THz SPW is increased by lowering the Fermi energy of the graphene sheet.

Published: February 2023

Abstract
This work examined the effect of changing molding conditions on the physical aging of polystyrene injection moldings. First, we investigated the relationship between the molecular orientation and the molding conditions. The molecular orientation near the surface changed with changing injection rate, so we hypothesized that this molecular orientation might form during the filling stage. Because this molecular orientation did not relax under heat treatment below the glass transition temperature (T
g), the oriented molecules near the surface were thought to be elongated owing to the high strain rate during the filling stage. On the other hand, the molecular orientation in the core layer changed with changing holding pressure and relaxed under heat treatment below T
g. Thus, the molecules in the core layer might become oriented during the holding stage and not be elongated owing to the slow strain rate. Furthermore, the molecular orientation in the core layer decreased with increasing mold temperature, and the physical heat resistance improved with increasing mold temperature. Meanwhile, the excess enthalpy did not change with changing molding conditions. Therefore, the improvement in physical heat resistance with increasing mold temperature was likely caused by the decrease in the molecular orientation in the core layer. Analyzing the relaxation behavior of the molecular orientation suggested that increasing mold temperature reduced the number of oriented molecules with large deformation in the core layer.

The form of emotions: the phonetics and morphology of interjections in Hadza
Authors: Andrason Alexander , Harvey Andrew , Griscom Richard 
Published: February 2023

Abstract
The present article provides the first systematic analysis of the formal (phonetic and morphological) facet of interjections in Hadza. By using a prototype-driven approach to an interjective category and drawing on original evidence, the authors demonstrate that Hadza interjections closely comply with an interjective prototype. Hadza interjections meet most prototypical features and the exceptions attested fully match the exceptions that have previously been observed in other languages. Overall, the study corroborates the validity of the prototype postulated in scholarly literature, although certain refinements are also proposed.
Explainable AI for sensor-based sorting systems

Published: February 2023

Abstract
Explainable artificial intelligence (XAI) can make machine learning based systems more transparent. This additional transparency can enable the use of machine learning in many different domains. In our work, we show how XAI methods can be applied to an autoencoder for anomaly detection in a sensor-based sorting system. The setup of the sorting system consists of a vibrating feeder, a conveyor belt, a line-scan camera and an array of fast-switching pneumatic valves. It allows the separation of a material stream into two fractions, realizing a binary sorting task. The autoencoder tries to mimic the normal behavior of the nozzle array and thus can detect abnormal behavior. The XAI methods are used to explain the output of the autoencoder. As XAI methods global and local approaches are used, which means we receive explanations for both a single result and the whole autoencoder. Initial results for both approaches are shown, together with possible interpretations of these results.

Abstract
A series of novel 2-(quinolin-2-yl)-spiro[oxindole-3,3′-pyrrolines] were synthesized by one-pot three-component reaction involving dimethyl acetylenedicarboxylate, 1-phenylimidazo[1,5-a]quinoline and N-alkylisatins in chloroform at ∼60 °C for 24 h. Structures of these new spiro derivatives were deduced from HRMS and NMR spectral data. A plausible mechanism for the observed thermodynamic control pathway is presented herewith. Interestingly, the spiro adduct, derived from 5-chloro-1-methylisatin, exhibited excellent antiproliferative activity on MCF7, A549 and Hela human cell lines (IC50 ≃ 7 μM).

Published: February 2023

Abstract
Although chest pain is a common chief complaint among pediatric patients, cardiac pathology historically has accounted for a small percentage of cases. However, the emergence of COVID-19 and particularly its potential for leading to multisystem inflammatory syndrome has changed the threshold for the evaluation of cardiac etiologies of chest pain. This evaluation often includes measurement of the serum cardiac troponin I level. We present a case of a 16-year-old male athlete who presented to an outside emergency department with chest pain and was found to have elevated serum troponin I levels. Despite sports restriction, his troponin level remained elevated for months in the absence of other clinical findings and he was subsequently referred to our outpatient pediatric cardiology clinic. Further laboratory evaluation revealed that, in addition to troponin I, the assay measured an immune complex of uncertain significance formed by anti-troponin I antibodies bound to troponin I, known as macrotroponin. Delayed clearance of this complex from the bloodstream can result in overestimation of troponin I levels that can affect clinical management and create anxiety for our patients and their families. Macrotroponin complex deserves increased recognition among the research and clinical communities, especially in the pediatric realm.

By analysing the methodologies it was possible to develop a comprehensive approach to creating high-value educational products. The article describes some of the proprietary technologies that the authors use when implementing proactive education programs in practice.The scientific novelty of the article lies in the formulation of the training concept for managers aimed at solving complex interdisciplinary tasks of a technological breakthrough. In terms of the practical value, the article presents a mix of educational technologies for the implementation of the concept. It includes electronic proactive leaning system, conveyor of continuous competence enhancement, digital modular architecture of the learning process, “module-in-module” technology.
Automatic Determination of Back Azimuth Based on a Single Mini Array for an Earthquake Early Warning System
Authors: Jung Seula , Park Jung-Ho , Seong Yun Jeong , Sheen Dong-Hoon 
Published: February 2023

ABSTRACT
Earthquake early warning (EEW) systems systematically monitor ground motion and provide alerts prior to damaging shaking. However, these systems present certain challenges, which include avoiding alerts caused by false triggers or delayed alerts for earthquakes from outside the seismic network. Here, we show that an array processing approach, which is capable of identifying the propagation direction and type of seismic phase, can overcome these challenges. In this study, a new automatic array processing approach was implemented using a single mini array to determine the back azimuth and slowness of the phases for local events. Seismograms of local events with ML 2.0–4.6 that occurred in the Korean Peninsula were analyzed using three array processing methods: beam packing, frequency–wavenumber, and plane-wave fitting. In addition, a combined P-wave picking procedure was introduced, and its performance was evaluated. We developed the criteria associated with slowness range and consistency of back azimuths to determine a stable back azimuth from the three array processing methods, estimating the back azimuth of the seismic phase with more accuracy than any single method. It is expected that seismic mini arrays and the developed automatic array processing approach can be used for network EEW systems to discriminate alarms caused by false triggers. In addition, the developed approach can be used for rapid onsite and front-detection warnings using the array inside or on the outskirts of a network when combined with other estimations, such as an epicentral distance or another back azimuth.

Authors: Salas Benítez César Mauricio 
Published: February 2023

Este artículo aborda los impactos derivados de la turistificación en el Parque Nacional El Tepozteco (PNT). Tal circunstancia ha provocado impactos ambientales y conflictos que han generado divisiones en la comunidad: por un lado, las autoridades, empresarios y actores ligados al turismo y, por otro, la población excluida de esta actividad. Así, se examina el escenario en el que priman los conflictos de intereses, la desconfianza, la falta de credibilidad y participación ciudadana y, cómo la población afectada ha hecho uso de los elementos del capital social para generar una organización comunitaria tendiente a la mitigación de los impactos negativos y a la negociación de las pautas de esta actividad. Este trabajo revela el proceso de turistificación en Tepoztlán, e identifica las acciones que la población organizada ha desarrollado para mitigar los efectos negativos. La metodología de trabajo usada en esta investigación se basa en el estudio de caso. Los datos se compilaron desde una variedad de fuentes (cualitativas y cuantitativas), para realizar una posterior triangulación.

Published: February 2023

El artículo expone cuáles han sido algunas de las condiciones sociales, económicas y políticas claves para comprender el surgimiento, desarrollo y debilitamiento de las empresas recuperadas por sus trabajadores (ERT) en Uruguay. Con la crisis socioeconómica del 2002 el fenómeno de las ERT alcanza una magnitud que lo hace visible socialmente. Encontramos a partir de allí un primer momento de emergencia y resistencia que se prolonga hasta finales del primer gobierno del Frente Amplio (FA) (2005-2010); un segundo contexto de crecimiento a partir del despliegue de la política pública durante el segundo gobierno del FA (2010-2015) y un tercer período de decrecimiento y cambio de perfil de las ERT a partir del desplazamiento de la política pública y el debilitamiento organizacional del sector (2015 hasta la actualidad).

Published: February 2023

Relevance. An important proviso for the commercially effective cultivation of vegetable crops in different types of greenhouses is high yield, which significantly depends on modern cultivars with different characteristics and properties. When creating a new cultivar, it is necessary to present its model in accordance with the expected ecological and agrotechnical conditions of planting, the purpose of use, the level of manifestation of morphological and biochemical characteristics, which together will ensure a high yield. The goal of research – to create early ripening, high-yielding cultivars of sweet pepper with high taste assessment of fresh fruits and content of biologically valuable substances.Materials and methods. The studies were conducted in 2015-2018 and 2020-2021 in the Belarusian State Agricultural Academy. The objects were 46 breeding lines of sweet pepper. An evaluation of fruits and plants morphological characteristics, yield traits, fruits biochemical composition, and tasting were carried out.Results. Valuable lines for breeding were selected with a gross yield of 5.60–6.71 kg/m2, with large fruits (150–220 g), thick pericarp (>7 mm),with a high content of biologically valuable substances and fruit quality 4.3–4.7 points. Lines with a complex of economically valuable traits including high tasting score, were transferred to the State Inspection for Testing and Protection of Plant Varieties and recommended for commercial use in the Republic of Belarus under the names Altyn, Chervonets, Karat, Goretsky Krasny, Garlachyk Zhovty and Chyrvony Magnat.
Influence of nitrogen stress on nitrate accumulation and yield of lettuce varieties
Authors: Volkova E. N. 
Published: February 2023

Relevance. Many authors note the existence of significant genotypic differences in the assimilation of nitrogen and the accumulation of nitrates by lettuce, point to the additive-dominant nature of the inheritance of the trait. The aim of the work was to evaluate the response of lettuce of various cultivars to mineral nutrition stress created against a nitrogen-deficient background (N0) and with an increased dose of nitrogen (N200).Material and Methods. In a microfield experiment on well-cultivated soddy-podzolic soil, a collection of lettuce varieties belonging to the main cultivated variety types was studied. The varieties differed in geographical origin, early maturity and morphological characteristics.Results. Differences in yield between varieties against the background of N200 were 4.5 times, and against the background of N0 – 5.7 times. Against an increased background of nitrogen nutrition, the highest yield – 2.22-2.64 kg/m2 was formed by the following varieties: All the Year, Quedlinburger Dickkopf, Berlin Yellow, Great lakes. Against a nitrogen-deficient background, Azart and Odessa Kucheryavets varieties stood out in terms of yield, which absorbed soil nitrogen better than others. The content of nitrates in lettuce plants of different varieties varied more strongly when grown on the background of N200 and ranged from 10.7 to 13.6 times (on average over 2 years – 11,2 times), on the control of N0 – 33 times. Varieties accumulating maximum NO3 under conditions of excess nitrogen nutrition were revealed. Lettuce Romaine (Lactuca romana) – 353 mg/kg and White paris cus (198 mg/kg) had a low content of NO3. The period of the maximum increase in biomass also corresponded to the maximum decrease in NO3 in plants. Power function equations were calculated to estimate the rate of change in biomass and NO3 content. The results indicate that there may be some scope for NO3 reduction in lettuce through cultivar selection or breeding.
