Flannery O’Connor’s Real Estate: Farming Intellectual Property
Authors: Shloss Carol Loeb 
Published: May 2021

Carol Shloss takes a literal approach to the subject of legacy by exploring and questioning the legal nature of Flannery O’Connor’s literary estate, a hot topic among many O’Connor scholars. Using “A Circle in the Fire” as a structural metaphor, Shloss argues that the disputes over ownership and property that are present in O’Connor’s fiction echo the reality of Flannery O’Connor’s personal literary estate. Shloss draws on extensive archival research in order to trace the history of O’Connor’s literary estate since the author’s death, while exploring the meaning of property in O’Connor’s work and positing how O’Connor’s writing itself becomes a type of property. Following the succession of O’Connor’s literary executors, Shloss identifies a tendency to move away from creativity about O’Connor and toward an enshirement of her image by a small number of people. Shloss argues that in the end, relaxing the copyright restrictions on O’Connor’s archive would best carry out the wishes of the author.
The clinical laboratory: a decision maker hub
Authors: Salinas María , López-Garrigós Maite , Flores Emilio , Martín Ester , Leiva-Salinas Carlos 
Published: May 2021

Abstract

Objectives
We aimed to share a new laboratory model based on laboratory knowledge, meaningful use of information technology, and partnership with clinicians, to lead the appropriate use of laboratory testing and clinical decision making in the diagnosis of as-yet-undiagnosed disease. More specifically, we evaluate the role of eight different opportunistic interventions to diagnose certain asymptomatic disorders, by means of the automatic registration of appropriate laboratory testing according to different scenarios.

Methods
This is a retrospective longitudinal study to evaluate the impact of laboratory interventions on the diagnosis of different diseases and on patient care, including data from January 2012 to September 2020.

Results
Overall, the above strategies have so far identified 2063 patients with clinically relevant as-yet-undiagnosed disorders who would have otherwise remained occult, such as for instance, primary hyperparathyroidism, diabetes, and hypomagnesemia.

Conclusions
We are facing a new laboratory model, a leading laboratory rather than a passive traditional laboratory, not just to intervene in clinical decision-making, but to make the clinical decision, through the identification of patients with occult disease.
Microsphere molecularly imprinted solid-phase extraction for diazepam analysis using itaconic acid as a monomer in propanol

Published: May 2021

Abstract
Diazepam (DZP) is a benzodiazepine drug used as an anti-drug and sedative. It is often misused to induce or create euphoria in combination with other drugs (high or fly sensation) or administered alone. So far, screening for DZP abuse with sensitive analytical methods is needed, as its small concentrations make it difficult to detect. Increased sensitivity of the analytical method can be obtained by using a preparation method that selectively separates the analyte from the sample matrix. Molecularly imprinted polymer (MIP) is one of the preparation solutions with good selectivity, specificity, and sensitivity. MIP was made from DZP as a template, itaconic acid, and ethylene glycol dimethacrylate in a composition of 1:4:20. MIP was made by precipitation polymerisation to obtain microsphere polymer type. MIP had a binding capacity value of 0.0557 mg/g and followed the Freundlich isotherm. Application of the microsphere MIP on spiked blood serum resulted in a recovery of 105.63 ± 1.0% for MIP compared to 21.28 ± 0.4% for non-imprinted polymer, with the imprinting factor value reaching 4.96. Hence, MIP DZP with itaconic acid as a functional monomer and propanol as a porogen, fabricated by the precipitation polymerisation method, is a promising sorbent for DZP extraction in biological fluids.
Strong convergence inertial projection algorithm with self-adaptive step size rule for pseudomonotone variational inequalities in Hilbert spaces
Authors: Wairojjana Nopparat , Pakkaranang Nuttapol , Pholasa Nattawut 
Published: May 2021

Abstract
In this paper, we introduce a new algorithm for solving pseudomonotone variational inequalities with a Lipschitz-type condition in a real Hilbert space. The algorithm is constructed around two algorithms: the subgradient extragradient algorithm and the inertial algorithm. The proposed algorithm uses a new step size rule based on local operator information rather than its Lipschitz constant or any other line search scheme and functions without any knowledge of the Lipschitz constant of an operator. The strong convergence of the algorithm is provided. To determine the computational performance of our algorithm, some numerical results are presented.
Ordered fields dense in their real closure and definable convex valuations
Authors: Krapp Lothar Sebastian , Kuhlmann Salma , Lehéricy Gabriel 
Published: May 2021

Abstract
In this paper, we undertake a systematic model- and valuation-theoretic study of the class of ordered fields which are dense in their real closure. We apply this study to determine definable henselian valuations on ordered fields, in the language of ordered rings. In light of our results, we re-examine the Shelah–Hasson Conjecture (specialized to ordered fields) and provide an example limiting its valuation-theoretic conclusions.
Retrieval of digital elevation models from Sentinel-1 radar data – open applications, techniques, and limitations
Authors: Braun Andreas 
Published: May 2021

AbstractWith the launch of Sentinel-1 in 2014, a new era of openly accessible spaceborne radar imagery was begun, and its potential has been demonstrated throughout all fields of applications. However, while interferometric approaches to detect surface deformations are continuously being published, only a few studies address the derivation of digital elevation models (DEMs) from Sentinel-1 data. This is mainly because of the narrow orbital tube, which was primarily designed for subsidence measurements using differential interferometry. Nonetheless, the technical conditions are provided for successful applications involving DEM generation. These are outlined in the first part of this article with a focus on potential error sources and the impact of the most important constraints, namely, temporal and perpendicular baselines. The second part evaluates 21 studies on this topic, their aims, and how they dealt with error sources and the necessity of validation. These studies are then discussed based on the main challenges and potentials including how these can be tackled in the future to lay a solid foundation for scientific discourse.
A Reconsideration and Elaboration of a Previously Proposed Hypothesis for the Origin of the —y of Spanish soy, doy, voy, estoy
Authors: Rini Joel 
Published: May 2021

Abstract
The origin of –y of Sp. soy, doy, voy, estoy remains unresolved to date. The present study reconsiders and elaborates the ‘post-verbal yo hypothesis’, originally proposed by Ford (1911), which has been rejected by most scholars because they have misunderstood it to suggest that the post-verbal subject pronoun yo became atonic and agglutinated to the verb, subsequently reducing to –y. It is suggested here that the phenomenon of ‘leftward palatal spreading’ from the post-verbal subject pronoun yo, with no agglutination nor reduction in form, first produced phonetic variants, e.g., so yo > ['soi̯-'yo], which were later morphologized and raised to allomorphic status before becoming full-fledged morphological variants upon extraction from the new syntagms, e.g., soy yo > soy (yo) > soy.
Fractional-order generalized Legendre wavelets and their applications to fractional Riccati differential equations
Authors: Yuttanan Boonrod , Razzaghi Mohsen , Vo Thieu N. 
Published: May 2021

Abstract
In the present paper, fractional-order generalized Legendre wavelets (FOGLWs) are introduced. We apply the FOGLWs for solving fractional Riccati differential equation. By using the hypergeometric function, we obtain an exact formula for the Riemann–Liouville fractional integral operator (RLFIO) of the FOGLWs. By using this exact formula and the properties of the FOGLWs, we reduce the solution of the fractional Riccati differential equation to the solution of an algebraic system. This algebraic system can be solved effectively. This method gives very accurate results. The given numerical examples support this claim.

Published: May 2021

Abstract

Objectives

Juglans regia L. is largely used by diabetic population, but its bark is scarcely investigated. The major aim of this study was to investigate the effect of the hydro-methanolic extract and fractions of J. regia L. barks on normoglycemic and diabetic rats through the evaluation of some biochemical parameters.

Methods
Phenolic enriched extracts were investigated for their effect on normoglycemic and diabetic rats through the determination of fasting blood glucose levels in short- and long-term. As well as plasma total cholesterol, triglycerides, insulin, urea, creatinine, alanine amino transferase (ALT) and aspartate amino transferase (AST) levels were measured after 28 days of treatment. Furthermore, the phytochemical composition was assessed by standard methods.

Results
Among the different extracts tested, the n-Butanol fraction presented the highest amounts of total phenolic, total flavonoids and flavonol contents (745 ± 0.6 mg GAE g−1, 162 ± 0.78 mg CE g−1 and 56.02 ± 0.92 mg QE g−1, respectively) and it found to be the most effective to decrease plasma total cholesterol, triglycerides and FGLs in treated diabetic rats in both short- and long-term treatment, mainly the dose 200 mg/kg after 28 days of treatment which found to be more effective than glibenclamide. This fraction also revealed pronounced improvement in liver and renal profiles.

Conclusions

J. regia L. barks had an important antidiabetic role similar to the reference glibenclamide. This may be related to the high contents of phenolic compounds.
Professional integrity in maternal – fetal innovation and research: an essential component of perinatal medicine
Authors: McCullough Laurence B. , Coverdale John H. , Chervenak Frank A. 
Published: May 2021

Abstract

Objectives
Clinical innovation and research on maternal–fetal interventions have become an essential for the development of perinatal medicine. In this paper, we present an ethical argument that the professional virtue of integrity should guide perinatal investigators.

Methods
We present an historical account of the professional virtue of integrity and the key distinction that this account requires between intellectual integrity and moral integrity.

Results
We identify implications of both intellectual and moral integrity for innovation, research, prospective oversight, the role of equipoise in randomized clinical trials, and organizational leadership to ensure that perinatal innovation and research are conducted with professional integrity.

Conclusions
Perinatal investigators and those charged with prospective oversight should be guided by the professional virtue of integrity. Leaders in perinatal medicine should create and sustain an organizational culture of professional integrity in fetal centers, where perinatal innovation and research should be conducted.
Comparison of the shear behavior in graphite-epoxy composites evaluated by means of biaxial test and off-axis tension test
Authors: Marín Juan Carlos , Barroso Alberto 
Published: May 2021

Abstract
Characterization of shear behavior in composite materials remains a not fully solved problem. In the last fifty years, many different approaches have been proposed to solve this problem (rail shear, thin-walled tube torsion, off-axis tensile, ±45° tensile, Arcan, Iosipescu, asymmetric four-point bend, plate twist, v-notched rail shear, off-axis flexural, and shear frame), although none of these approaches have achieved an unquestionable solution. For this reason, proposals of alternative methods and comparison between different experimental techniques are of interest. In the present work, the use of cruciform samples with the fiber oriented at 45° with respect to the load directions, and subjected to tension-compression (creating a pure shear stress state at the central part of the samples), is studied. The experimental results of the cruciform samples have been compared with the off-axis tests (with the fiber at 10°) for the same material (AS4/8552), finding a good agreement between the shear experimental curves, especially at the initial part of the curve, where the shear modulus is calculated. Nevertheless, the shear strength value obtained by means of the cruciform specimen has shown to be significantly lower than that obtained using the off-axis test. A Finite Element numerical model of the cruciform specimen has been developed to analyze the stress field of the samples. Numerical results have shown that there is a central area of the cruciform specimens where a pure and uniform shear stress state is developed, which is suitable for the evaluation of the shear constitutive law of the material. It has been observed that there is a (σ
22) stress concentration in the transition between the straight and curved parts of the boundary geometry of the samples, which explain some premature failures of the samples. This premature failure could be avoided with tabs extended up to the beginning of the central part of the sample.
Study of gypsum composites with fine solid aggregates at elevated temperatures
Authors: Doleželová Magdaléna , Scheinherrová Lenka , Vimmrová Alena 
Published: May 2021

AbstractThe structure and behaviour of two gypsum composites after exposition to elevated temperatures were investigated. The silica sand and fine basalt aggregate were used as solid fillers. The changes in structure and composition at temperatures from 50 to 1,000°C were investigated by scanning electron microscopy and X-ray diffraction together with the size and strength of the samples and their pore size distribution. The structure of gypsum matrix changed significantly at 1,000°C in both composites, while the aggregate particles were not changed. It was found that even if the silica sand is considered as less suitable filler at high temperatures because of its volume changes, the gypsum with sand performed better than gypsum with basalt at the highest temperatures, because the shrinkage of the gypsum matrix was compensated by the increase in the volume of aggregate. The final volume change at 1,000°C was 3.5% in composite with silica sand and 6.8% in composite with basalt. The residual compressive strength of both composites was about 9.4%. No cracks appeared in the samples and no spalling was observed.
LA BATALLA DE SANTIAGO. CRÓNICA DE UNA CUARENTENA EN LA CAPITAL DE CHILE
Authors: Azócar Guzmán Pedro 
Published: May 2021

La pandemia de covid-19 golpeó a Chile en medio de una crisis político social caracterizada por una dura confrontación entre la ciudadanía y sus instituciones, además, de una profunda crítica al modelo económico instaurado por la dictadura de Augusto Pinochetcuyo sustento institucional es la Constitución de 1980. El gobierno derechista de Sebastián Piñera intentó sacar réditos políticos de la pandemia del coronavirus, utilizarla para reafirmarse en el poder, pero la emergencia sanitaria evidenció aún más las profundas desigualdades sociales que subsisten en el país a 30 años de la recuperación de la democracia. Chile aparece doblemente golpeado: por un lado, enfrenta una profunda fractura social y, por otro lado, sufre la debacle del coronavirus. En este complejo cuadro, los chilenos deberán resolver, mediante un plebiscito, si convocan o no a una convención constituyente para sepultar definitivamente la Constitución de Pinochet. Este artículo es una aproximación a ese escenario.

An extension of the method of numerical integration of seismograms to include a third integration*
Authors: Walter Edward J. 
Published: May 2021

Abstract

Summary and Conclusions
The problem of numerical integration of galvanometrically recorded seismograms involving three successive integrations is considered and the following conclusions are reached:
The method was applied to a test record of known motion which was approximately harmonic. In the development of the method there is nothing that seems to require such motion, but the transients excited in the recording system at the beginning of the motion effectively limit the accuracy of the results to that portion of the record which corresponds to a steady state.
The continental layers of Europe‡
Authors: Stoneley Robert 
Published: May 2021

Summary
The observed period and group velocities of Love waves propagated across Eurasia indicate that the thicknesses T1 and T2 of the granitic and intermediate layers of Eurasia satisfy the approximate equation 2T1 + T2 = 65.5 ± 6 km. If the equation obtained by Jeffreys from Japanese deep-focus earthquakes, T1 + 0.85 T2 = 30.3 ± 1.3 km., is accepted, we find T1 = 36.2 ± 7.4 km., T2 = −6.8 ± 9.4 km., implying that the thickness of the intermediate layer is not significantly different from zero. Taking T2 = 0 would then give T1 = 33 ± 3 km.
This value does not seem compatible with the observed rate of outflow of heat; but the data concerning the rate of generation of heat through radioactive disintegration are very uncertain. Combined with the Love-wave equation, the isostatic equation indicates a thickness of about 30 km. for the floor of the Pacific Ocean; this is in general agreement with the work of Byerly and Vening Meinesz.
The deep-focus earthquake equation then indicates that the base of the granitic continent, without any “intermediate layer,” should be at about the same level as the lower surface of the basalt layer under the Pacific Ocean, both continent and ocean floor resting on the horizontal surface of ultrabasic material. The need for further investigations into the propagation of surface elastic waves is manifest.
Caracterización cinética e hidrodinámica del fluido en un floculador hidráulico tipo Alabama localizado en la Ptap “El Arroyo” en Santander de Quilichao, Cauc

Published: May 2021

Se caracterizó la energía cinética y la hidrodinámica del fluido en un floculador hidráulico tipo Alabama de la PTAP EL Arroyo del municipio de Santander de Quilichao – Cauca. Para ello, se realizó la evaluación experimental mediante tres ensayos de trazadores complementándolos con la simulación a través de un modelo CFD en tres dimensiones (CFD-3D). Se utilizó un enfoque Euleriano junto con un modelo de turbulencia “Viscous – estándar k-ε” para caracterizar el fluido, el modelo se implementó usando el software Ansys Inc. Fluent® (V.16.1) en una estación de trabajo Dell Precision TX3500. La geometría correspondió a un modelo CAD con las dimensiones reales del floculador y se desarrolló usando el programa Ansys Design Modeller®. La malla para las simulaciones fue discretizada con 20795 elementos hexaédricos usando Ansys Inc® meshing software (V.16.0). Los resultados mostraron que el floculador opera en condiciones que afectan su desempeño desde el punto de vista hidrodinámico y cinético del fluido, que funciona como un reactor no ideal presentando un flujo mezclado con tendencia a flujo pistón, además, la existencia de cortos circuitos y zonas muertas que disminuyen su eficiencia y deterioran la calidad de los flocs. Los resultados de la simulación se proponen como complementarios al clásico ensayo de trazadores y a la evaluación de este tipo de unidades propuesta en el RAS 2010. Esto, gracias a que las simulaciones computacionales mostraron en detalle las causas y las zonas del floculador donde se presentaban las fallas hidráulicas adversas al buen funcionamiento de este. En conclusión, con la ayuda del modelo se propusieron acciones de mejoramiento como el cierre de las ventanas de limpieza durante la operación del floculador, evitar cambios bruscos en los caudales de operación y la instalación de codos de dirección del flujo en los compartimentos del mismo.
Schwannoma of the First Webspace
Authors: Alçada Rita , Caetano João , Barreiros Margarida , Côrte-Real Nuno 
Published: May 2021

Case:
A 65-year-old man presented with plantar foot pain associated with a mass in the first webspace. A Morton neuroma was considered the probable diagnosis. Despite nonoperative treatment the pain continued. Surgical excision was performed, and histology was interpreted as a schwannoma. Symptoms resolved after surgery.

Conclusion:
Schwannoma of the foot is a rare condition, and to the best of our knowledge, this is the first case reported in the first webspace. Definitive treatment and diagnosis is surgical excision. Surgeons should consider schwannomas in the differential diagnosis of plantar foot pain because this can be misdiagnosed as a Morton neuroma.

Published: May 2021

Case:
A 40-year-old man presented with limited in range of motion, pain, and tenderness over the medial joint line after an open reduction and internal fixation (ORIF) because of a bicondylar tibial plateau fracture (TPF). The cause of his pain was inconclusive on Magnetic Resonance Image (MRI), so arthroscopy was performed and identified an incarcerated medial meniscus at the fracture site. An osteotomy with medial joint elevation was performed followed by a meniscus release, with excellent results at the 1-year follow-up.

Conclusion:
To our knowledge, this is the first case reporting a trapped/incarcerated meniscus in a healed TPF after ORIF.
