Vitreous cortex hyalocytes are resident macrophage cells that help maintain the transparency of the media, provide immunosurveillance, and respond to tissue injury and inflammation. In this study, we demonstrate the use of non-confocal quadrant-detection adaptive optics scanning light ophthalmoscopy (AOSLO) to non-invasively visualize the movement and morphological changes of the hyalocyte cell bodies and processes over 1-2 hour periods in the living human eye. The average velocity of the cells 0.52 ± 0.76 µm/min when sampled every 5 minutes and 0.23 ± 0.29 µm/min when sampled every 30 minutes, suggesting that the hyalocytes move in quick bursts. Understanding the behavior of these cells under normal physiological conditions may lead to their use as biomarkers or suitable targets for therapy in eye diseases such as diabetic retinopathy, preretinal fibrosis and glaucoma.

Published: February 2022

Looking for materials with compelling nonlinear optical (NLO) response is of great importance for next-generation nonlinear nanophotonics. We demonstrate an escalated two-photon absorption (TPA) in ultrasmall niobium carbide quantum dots (Nb2C QDs) that is induced by a two-even-parity states transition. The TPA response of Nb2C QDs was observed in the near-infrared band of 1064–1550 nm. Surprisingly, at 1064 nm, Nb2C QDs shows an enhanced TPA response than other wavelengths with a nonlinear absorption coefficient up to a value of 0.52 ± 0.05 cm/GW. Additionally, the nonlinear optical response of Nb2C changes to saturable absorption when the incident wavelength is between 400–800 nm wavelength. Density functional theory (DFT) validates that TPA, induced by two even-parity states transition, breaks the forbidden single-photon transition, enabling a tremendous TPA response in Nb2C QDs at 1064 nm. It offers the possibility of manipulating the NLO response of Nb2C via morphology or surface termination.

Published: February 2022

Spectral broadening of optical frequency combs with high repetition rate is of significant interest in optical communications, radio-frequency photonics and spectroscopy. Silicon nitride waveguides (Si3N4) in the anomalous dispersion region have shown efficient supercontinuum generation spanning an octave-bandwidth. However, the broadening mechanism in this regime is usually attained with femtosecond pulses in order to maintain the coherence. Supercontinuum generation in the normal dispersion regime is more prone to longer (ps) pulses, but the implementation in normal dispersion silicon nitride waveguides is challenging as it possesses strong requirements in propagation length and losses. Here, we experimentally demonstrate the use of a Si3N4 waveguide to perform coherent spectral broadening using pulses in the picosecond regime with high repetition rate. Moreover, our work explores the formation of optical wave breaking using a higher energy pulse which enables the generation of a coherent octave spanning spectrum. These results offer a new prospect for coherent broadening using long duration pulses and replacing bulky optical components.

Published: February 2022

We have explored an orbital angular momentum (OAM) amplifier of 10 vortex modes under different-order OAM pump modes, i.e. OAM0, OAM1, and OAM2. The all-fiber amplification system consists of an active few-mode erbium-doped fiber (FM-EDF), a mode selective pump (MSP), and a mode selective signal (MSS). These mode selective components are based on fused-taper mode selective couplers (MSC) under different wavelengths fabricated by a passive ring-core fiber (RCF). Under different-order mode pumps, the OAM amplifier experimentally exhibits mode gains (MGs) above 15 dB for 10 vortex modes with the mode purities only 89%, essentially in line with the simulation results. Especially when the signal-mode profiles are better matched to the pump-mode profiles, i.e. the OAM pumps with the same order as signals, the obtained MGs are all over 20.2 dB and the amplified OAM mode purity is up to 97%; the acquired noise figures (NFs) are <4.9 dB and even the minimum NF is 3.2 dB. The results reveal that the OAM amplifier shows low-NF and high-purity characteristics under configurable pump modes in C-band. The amplified high-order OAM mode could be promising for uses in the long-distance mode division multiplexing (MDM) and in mitigation of the upcoming capacity crunch in optical fiber communication.
Rapid customized design of a conformal optical transparent metamaterial absorber based on the circuit analog optimization method
Authors: Dong Lin , Si Liming , Xu Haoyang , Shen Qitao , Lv Xin , Zhuang Yaqiang , Zhang Qingle
Published: February 2022

In this paper, a conformal optical transparent metamaterial absorber (COTMA) is proposed based on the circuit analog optimization method (CAOM), which can effectively enhance the optimization speed in the metamaterial absorber structure design by quantifying the equivalent circuit parameters. The operating frequency band can be customized at any band through CAOM, such as microwave, terahertz, and near-infrared frequencies. Here, a five-square-patch structure absorber with transparency and flexible properties is achieved. The simulated and measured incident electromagnetic (EM) wave absorptions of COTMA can reach above 90% in 15.77 - 38.69 GHz band. Meanwhile, COTMA exhibits excellent conformal EM absorption, a thinner substrate (0.078 wavelength at 15.77 GHz), lower structure complexity and polarization independence, and it can also be adapted to the EM absorption of different curved screens. This design is expected to have potential applications for wearable electronics, curved surface screens and OLED displays.

Published: February 2022

O objetivo deste artigo é discutir as dualidades entre o sistema alimentar moderno, vinculado à produção de alimentos ultraprocessados por grandes corporações ligadas à alimentação, em oposição ao modelo tradicional, vinculado a produtos in natura com qualidade nutricional. Busca-se compreender as políticas do estado brasileiro quanto à garantia do direito humano à alimentação saudável (DHAA). Metodologicamente o artigo é construído a partir de uma revisão sistemática da literatura, utilizando bases Miltonianas como a de Saquet e Silva (2008) e Abrão (2010) para a compreensão do problema proposto. O resultado encontrado pelo estudo é que a capacidade de articulação da grande indústria alimentícia promove um território alimentar que está em uma disputa perene, especialmente devido ao amplo poder da grande indústria de se perpetuar pelo território inserindo seus produtos. Conclui-se portanto que o estado brasileiro dispõe de um arcabouço legislativo com intuito de garantir o DHAA. Entretanto, por fatores vinculados ao ambiente político e ao próprio interesse dos grandes grupos alimentares, as políticas públicas não são colocadas em prática de sua forma completa. O combate a esses problemas deve ser pautado politicamente, dessa forma podemos utilizar a dinâmica territorial do Sistema Único de Saúde (SUS) para solucionar esse problema.

»dare intellectum salutis populi eius …« (Lc 1,77) Der Codex Bezae und der lateinische Text der lukanischen Cantica
Authors: Bauer Thomas Johann
Published: February 2022

Der zweisprachige Codex Bezae (Cantabrigiensis) ist eine der prominentesten Handschriften und ein wichtiger Zeuge des griechischen und lateinischen Textes der Evangelien und der Apostelgeschichte. Zahlreiche Besonderheiten und singuläre Lesarten lassen fragen, wie er in die Textgeschichte des griechischen und lateinischen Neuen Testaments eingeordnet werden kann. Am Beispiel der lukanischen Cantica lässt sich zeigen, dass erst eine möglichst vollständige Berücksichtigung des Materials ein differenziertes Urteil über Herkunft und Entstehung seines Textes erlaubt und tatsächliche Wechselwirkungen zwischen dem Text der benutzten griechischen und lateinischen Vorlagen identifizierbar macht.
Kinetics of Formation and Characterization of Green Silver Nanoparticles of Ficus variegata Leaf Extract
Authors: Wattimena Synodalia C. , Ririmasse Violin , Killay Amos , Patty Philipus J.
Published: February 2022

This study aimed to determine the formation rate of silver nanoparticles synthesized using leaf extract of Ficus variegata and characterize their physical, chemical, and antibacterial properties against Gram-positive Staphylococcus aureus and Gram-negative Escherichia coli. For the formation rate determination, an empirical exponential model was proposed and used to fit the absorbance vs. time data (kinetics data). The surface plasmon resonance wavelength was measured using UV-Vis spectroscopy for physical and chemical characterization. The shape and size of the silver nanoparticles were characterized by transmission electron microscopy (TEM), and organic materials on the surface of the particles were identified by characterizing the associated chemical bonding using FTIR spectroscopy. For antibacterial assays, disc diffusion and spectrophotometric methods were used. The formation rates of the silver nanoparticles were 0.036 per hour or 1.0 x 10-5 s-1 (slower rate) and 0.767 per hour or 2.1 x 10-4 s-1 (faster rate). UV-Vis absorption spectrum indicated the surface plasmon resonance peak at 415 nm. Silver nanoparticles formed mainly were spherical, with a mean diameter of 26.5±0.7 nm. The FTIR spectrum indicated the presence of organic materials on the surface of the silver nanoparticles, which indicated the involvement of the extract as a reducing agent in particles formation. Antibacterial assay showed that synthesized silver nanoparticles inhibited the growth of both S. aureus and E. coli. The results from the disc diffusion method imply that the particles inhibited the growth of E. coli more effectively than S. aureus.
The bioinspired traffic sign classifier
Authors: Przewlocka-Rus Dominika , Kryjak Tomasz
Published: February 2022

Objectives

In this paper the research on developing convolutional spiking neural networks for traffic signs classification is presented. Unlike classical ones, spiking networks reflect the behaviour of biological neurons much more closely, by taking into account the time dimension and event-based operation. Spiking networks running on dedicated neuromorphic platforms, such as Intel Loihi, can operate with greater energy efficiency, hence they are an interesting approach for embedded solutions.

Methods

For convolutional spiking neural networks' design and simulation, Nengo and NengoDL libraries for Python language were used. Numerous experiments using the Leaky-Integrate-and-Fire (LIF) neuron model were conducted. The training results, with different augmentation methods and number of time steps for input image presentation were compared.

Results

Finally, an accuracy of up to 97% on the test set was achieved, depending on the number of time steps the input was presented to the SNN.

Conclusions

The proposed experiments show that using simple convolutional spiking neural network, one can achieve accuracy comparable to the classical network with the same architecture and trained on the same dataset. At the same time, running on dedicated neuromorphic hardware, such solution should be characterized by low latency and low energy consumption.
NADPH-derived ROS generation drives fibrosis and endothelial-to-mesenchymal transition in systemic sclerosis: Potential cross talk with circulating miRNAs

Published: February 2022

Systemic sclerosis (SSc) is an immune disorder characterized by diffuse fibrosis and vascular abnormalities of the affected organs. Although the etiopathology of this disease is largely unknown, endothelial damage and oxidative stress appear implicated in its initiation and maintenance. Here, we show for the first time that circulating factors present in SSc sera increased reactive oxygen species (ROS) production, collagen synthesis, and proliferation of human pulmonary microvascular endothelial cells (HPMECs). The observed phenomena were also associated with endothelial to mesenchymal transition (EndMT) as indicated by decreased von Willebrand factor (vWF) expression and increased alpha-smooth muscle actin, respectively, an endothelial and mesenchymal marker. SSc-induced fibroproliferative effects were prevented by HPMECs exposition to the NADPH oxidase inhibitor diphenyleneiodonium, demonstrating ROS’s causative role and suggesting their cellular origin. Sera from SSc patients showed significant changes in the expression of a set of fibrosis/EndMT-associated microRNAs (miRNA), including miR-21, miR-92a, miR-24, miR-27b, miR-125b, miR-29c, and miR-181b, which resulted significantly upregulated as compared to healthy donors sera. However, miR29b resulted downregulated in SSc sera, whereas no significant differences were found in the expression of miR-29a in the two experimental groups of samples. Taking together our data indicate NADPH oxidase-induced EndMT as a potential mechanism of SSc-associated fibrosis, suggesting fibrosis-associated miRNAs as potentially responsible for initiating and sustaining the vascular alterations observed in this pathological condition.
Geometric approximations to transition densities of Jump-type Markov processes
Authors: Zhuang Yuanying , Song Xiao
Published: February 2022

This paper is concerned with the transition functions of symmetric Levy-type processes generated by a pseudo-differential operator with variable coefficients. We first give the general estimates of heat kernels of jump diffusion semigroups, which leads to diagonal estimates of transition function and subordination in the context of two-dimensional Cauchy semigroup. Then off-diagonal estimates of special classes of Levy-type processes where transition function can be expressed using the diagonal estimation results and related metrics are derived. Furthermore, we show geometric approximation of the general two-dimensional Levy processes, and graphical experiments have been made by freezing the coefficients of the generators.

Direct Tension Testing of Plain and Fiber Reinforced Concrete for Use in Additive Construction
Authors: Pierson Matthew C. , Pinkerton Luke R.
Published: February 2022

An understanding of the tensile capacity of plain and fiber-reinforced concrete is needed for design. Typical designs use correlations based on the flexural capacity of a prismatic beam. Because of anisotropy, however, determining tensile capacity from correlations is more uncertain in additive manufacturing. Therefore, a simple and reliable method for measuring the direct tension of concrete is needed. This paper describes and evaluates a direct tension test of fiber-reinforced concrete that is being developed in ASTM Subcommittee C09.42 on Fiber-Reinforced Concrete. Alternate specimen geometries are discussed, and select results from 100 tests are evaluated statistically. Modifications to the method for use in additive manufacturing are proposed and qualitatively described.
Rheological and Thermal Characterization of 3D Printable Lightweight Cementitious Composites with Fly Ash Cenospheres
Authors: Kilic Ugur , Yang Yang , Ma Ji , Ozbulut Osman E.
Published: February 2022

This study investigates the development of fly ash cenospheres (FACs)–based lightweight cementitious composites that can be used as both structural and nonstructural material in digital construction. FACs are hollow alumino-silicate particles obtained as a by-product of a thermal power plant's coal combustion. To fabricate 3D-printable lightweight cement composites, ordinary Portland cement, fine sand, silica fume, water, FACs, superplasticizers, and viscosity-modifying agents (VMA) were used. The effects of the FACs volume ratio and VMA ratio on the rheological and thermal properties of the developed composites were studied. First, stress growth tests were conducted to determine the yield stress and apparent viscosity of the FACs-based cement mixtures with four different FACs volume ratios and four different VMA ratios. A heat flow meter technique was employed to determine the thermal conductivity and thermal resistance of the developed composites with different FACs volume ratios. Prismatic specimens were cast and cured for 28 days for thermal tests. Before thermal measurements were conducted at room temperature, the specimens were dried in an oven until they reached a constant weight. In addition, cubic specimens were prepared to determine the compressive strength of the developed composites. The morphological and microstructural characteristics of the tested compression specimens were analyzed using a scanning electron microscope. The printability of the most promising mixture proportion was assessed using a 3D concrete printer equipped with a screw pump and two different nozzles. Results showed that increasing the VMA ratio or FACs content decreased the thermal conductivity of cementitious mixtures, while the rate of this decrease was higher for increasing FACs volume ratios. By replacing 60% of sand with FACs and using VMA at 0.3% by weight of binder in a mortar composite, a printable lightweight cementitious composite with good thermal and mechanical properties could be obtained.
Determination of Mechanical Properties of Additively Constructed Concrete Based on Specimen Orientation
Authors: Stidwell Samuel , Kreiger Eric L.
Published: February 2022

As more applications of additive concrete construction (ACC) continue to be explored, some, such as buildings and bridges, call for a focus of structural integrity. It is essential that the material properties of multilayered additively constructed elements be determined prior to use to ensure that the strength meets or exceeds the requirements of the application. The layered deposition process of concrete additive construction introduces anisotropy in fabricated elements, which can be due to interface weakness or inherent geometric discontinuities. The weaknesses can be the result of the ACC process (material extrusion, print speed, and print stability) or the printable material properties (water content, curing rate, fibers, aggregate size) leading to variation in mechanical properties. Typical cast concrete elements are assumed to be isotropic, meaning that mechanical behavior is not affected by element orientation. Therefore, it is critical that ACC elements be tested for the effects of orientation on mechanical properties, as this can affect the mechanical behavior of structural elements. This study proposes six potential tests to characterize the mechanical properties of ACC and explores the effect of orientation on the mechanical properties of specimens cut from multilayered ACC elements. Specimens were tested for compressive strength under two principal orientations (Y and Z), bending strength under two orientations (X and Z); and two different interface strength tests (using splitting tension and direct shear). The resulting compressive strengths exceeded the compressive limit of 1,900 psi (13.1 MPa), flexural strengths were high at 36% to 41% of the compressive strength results, depending on orientation. Direct shear and splitting tensile strength of the layer-layer interfaces were 14.6% to 16.6% and 9% to 10% of the compressive strength results, respectively. Overall, the orientation of the specimen did not seem to have much effect on performance for this particular material.
Effect of Layer Height on Tensile Stress Distribution and Crack Width-and-Propagation in 3D Printed Fiber-Reinforced Flexural Elements
Authors: Nair Sooraj A. O. , Li Anling , Mobasher Barzin , Neithalath Narayanan
Published: February 2022

This paper evaluates the effect of layer height on the flexural response and crack propagation behavior of 3D-printed steel fiber-reinforced mortar beams. Beams printed with three different layer heights (5, 10, and 15 mm), with other dimensional and printing parameters maintained the same, were tested in four-point bending. The flexural strength increased with layer height in the range explored. Fiber lengths larger than the layer height introduced enhanced interlayer defects. Flexural load-deflection data were employed to determine a constitutive tensile stress-strain relationship. Digital image correlation (DIC) was used to measure the crack width along the depth, along with the strain profile. The relationships between stress and crack width were developed as a function of distance from the neutral axis, which demonstrated higher residual stress at a given crack width for the specimens with higher layer height. The study shows that a small amount of fibers in 3D-printed mixtures ensures better mechanical properties and that higher layer heights (within the limits used here) are beneficial in terms of mechanical behavior and speed of construction.

Published: February 2022

After only a few years of intensive research all over the world, 3D printing of buildings has become possible. However, existing design codes do not cover all the special technical features of the new construction method. Therefore, it is necessary to develop supplementary and adapted test procedures as well as design standards. In addition, a building permit (approval for individual case) must be issued. In this paper, we describe a concept to obtain an approval for individual case for the construction of the first 3D-printed detached house in Beckum, Germany, following existing standards for concrete and masonry construction. To choose the right test methods, one must know the design of the building, the additive manufacturing technique, the material, and the production environment. In the presented case, the house was completely built on the building site. The design of the house used 3D-printed parts for inner and outer walls for load-bearing and non-load-bearing elements. For this purpose, material properties such as setting, direction-dependent strength, and durability were tested. However, due to the scope of the paper, only flexural strength measurements are addressed here. All investigations focused on the formation of cold joints due to breaks in the construction process and the environmental impact. However, due to scale effects, testing of large-scale elements was necessary. In particular, larger wall elements showed decreased flexural strength compared to smaller specimens (prisms). Therefore, we present a concept for testing the load-bearing performance of wall elements and their resistance to the pressure of fresh concrete. All tests were successfully applied, characteristic design values were provided, the approval for individual case was granted, and the construction process began.

En Costa Rica, los proyectos de vivienda de interés social desarrollados en la última década, se hanlocalizado en zonas alejadas de centros urbanos o con limitado acceso a equipamientos e infraestructuras, debido al elevado costo del suelo en los sectores más céntricos de la ciudad. Las condiciones y características de estos entornos, los usos del suelo, las configuraciones morfológicas, la continuidad y la contigüidad entre los proyectos de Vivienda de Interés Social y las piezas urbanas donde se insertan, son analizadas en esta investigación, a través del estudio de cinco conjuntos residenciales desarrollados en la Gran Área Metropolitana. Los proyectos, construidos entre 2011 y 2018, fueron analizados a partir del estudio de planos, cartografía del ámbito, revisión documental y estudio de datos secundarios. Los resultados alcanzados posibilitaron identificar las principales dificultades desprendidas del encaje morfológico y tipológico que siguieron los conjuntos residenciales, así como las problemáticas contextuales por la locación de los proyectos
Inundaciones por zonas funcionales en la subcuenca Santa Rosa Jáuregui, Querétaro, México
Authors: Hernández Guerrero Juan Alfredo , Oreano Hernández Dulce Sonia
Published: February 2022

En la periferia urbana de la ciudad de Querétaro, las inundaciones son más frecuentes y peligrosas. El proceso parece acentuarse conforme se altera la estructura y función de las cuencas hidrográficas. El presente trabajo analizó la formación de inundaciones por zonas funcionales en la subcuenca Santa Rosa Jáuregui, Querétaro. Al respecto, se elaboraron zonas funcionales con variables hidrogeológicas en un sistema de información geográfica, se definieron unidades y secciones con análisis hidrogeomorfológico y se recopilaron registros de inundaciones con trabajo hemerográfico. Los resultados señalan que la zona funcional alta tiene una estructura óptima que beneficia cuenca abajo, pero las alteraciones hidrogeomorfológicas en la zona funcional media favorecen la formación de inundaciones en la zona funcional baja, la cual también cuenta con la urbanización de la llanura de inundaciones. A través de zonas funcionales, se determinó que las inundaciones resultan de procesos sistémicos y acumulativos que pueden ser utilizados en la gestión y mitigación de riesgo.
Tooth whitening in conventional orthodontic patients: a systematic review
Authors: Hernández-Viana Stefanía , Niño Miguel Fernando , Restrepo Felipe Augusto , Botero Javier Enrique
Published: February 2022

This systematic review aimed to identify and critically evaluate the available evidence of the appropriate moment to perform tooth whitening in conventional orthodontic patients. A systematic review in MEDLINE and SciELO databases from inception to February 2021 was carried out by two independent reviewers. Randomized clinical trials, non-randomized clinical trials, case-control, cohort, cross-sectional, case-series and reviews that focused on the application of tooth whitening during or after orthodontic treatment were considered for inclusion. The primary outcome was defined as tooth whitening during/after orthodontic treatment. The secondary outcome included the time in days after bracket debonding in which tooth whitening was performed. Risk of bias analysis was performed for each study and the findings were synthesized in a narrative summary. A total of 4 randomized clinical trials, 1 non-randomized clinical trial and 3 reviews were included in the qualitative synthesis. One study performed tooth whitening during, and three studies after orthodontic treatment. One study compared tooth whitening during and after orthodontic treatment. The time after which tooth whitening was applied following bracket debonding ranged from 7 to 90 days with a mean value of 40.2 days. All studies reported satisfactory improvements in tooth color shade during or after orthodontic treatment independent of the protocol. Low quality evidence suggests that the appropriate moment to perform tooth whitening in conventional orthodontic patients is after brackets removal with a waiting period of at least 30 days. There is not adequate evidence to support tooth whitening during conventional orthodontic treatment.
Emociones asociadas al proceso de construcción del volumen del paralelepípedo
Authors: Vinces-Vinces Fabricio Vladimir , Giraldo-Rojas Juan David , Parraguez-González Marcela Cecilia , Zabala-Jaramillo Luis Albeiro
Published: February 2022

Este estudio tiene como objetivo analizar las emociones en los estudiantes de entre 14 y 17 años de edad, al construir de manera autónoma en el software Cabri II Plus una caja rectangular en 2D y 3D que represente el volumen de un paralelepípedo. La metodología se basó en análisis de frecuencias por medio de mapas de calor construidos con la herramienta computacional Python. Bajo una muestra no probabilística y previo consentimiento informado de sus representantes legales se seleccionaron 34 estudiantes de Noveno Grado de Educación Básica de una institución educativa pública de la ciudad de Medellín-Colombia, de los cuales participaron 28 en esta investigación. La indagación consideró a la emoción desde una perspectiva integral, cimentada desde lo evolutivo, lo fisiológico-neural, cognitivo, volitivo y expresivo. Para acceder a estas se utilizó el software FaceReader, software especializado en detectar expresiones faciales. El resultado mostró que, a partir de dificultades en el proceso de construcción, emergen emociones como la tristeza, enojo, neutralidad, miedo, disgusto y sorpresa. En la población estudiada, se infiere una correlación entre la capacidad de procesamiento emocional y el procesamiento cognitivo. Se concluyó que, ante dificultades de construcciones geométricas de trazo de rectas paralelas, rectas perpendiculares, la diferencia entre punto y punto de intersección y la relación entre el volumen de paralelepípedo en 2D y 3D, emergen emociones negativas asociadas a la falta de dominio de estos conceptos que, si los y las estudiantes no pueden autorregular, les inhiben el procesamiento cognitivo, les producen bloqueo y, en consecuencia, abandono de la tarea.
A vida-morte como ritual cotidiano
Authors: Peretti Clélia , Dos Santos Mendes Everaldo , Cardoso Ribeiro Edilmar
Published: February 2022

Neste artigo, refletimos sobre a vida-morte como ritual cotidiano frente à COVID-19. Na metodologia, delineamos uma pesquisa qualitativa, historiobiográfica, que reuniu os escritos de Edith Stein, Dulce Critelli e a narrativa de Osmair Cândido. Interessou-nos o modo como a filosofia alemã ajuda Cândido no enfretamento dos horrores da pandemia, como tirar o caixão de um filho das mãos da mãe ou enterrar doze pessoas no mesmo dia, sem ritos fúnebres. Perpendicular à parede que lhe surge, desvela-se outra, amparando os cadáveres por ele empilhados. Cândido confessa sentar-se à margem de tudo, à beira do mundo, onde até Deus termina.
Necroecoteología. Hermenéutica contrahegemónica en tiempos de pandemia
Authors: Toledo Alcalde José Octavio
Published: February 2022

El presente artículo se aproxima al tema de los fines depredadores de la instrumentalización, colonial y neocolonial, de la fe con base cristiana, la antropología, la ecología, y la política. Se propone el neologismo necroecoteología y la subjetividad instrumental como llaves de interpretación transdisciplinarias del desequilibrio humano-ambiental, sobre todo en tiempos de crisis planetaria como la que nos impone la pandemia. De igual forma, se muestra el punto de inflexión entre la secularidad europea y la subjetividad religiosa colonial impuesta en tierras invadidas. Desde trabajos de activistas de la teología y filosofía de la liberación, derechos humanos, y disciplinas afines, se vincula teología, política y ecología en una misma plataforma de análisis, discusión y propuestas de alternativas resolutivas. Se concluye con una de estas propuestas, otro neologismo, la ecosacralidad, una visión contrahegemónica más allá del mundo cristiano, que busca re-eequilibrar y re-unir la relación humano-ambiental.
Additions to the Сommentary (Based on F. M. Dostoevsky
Authors: Zavarkina Marina
Published: February 2022

The article analyzes certain proper names and titles of the works from the 1860s notebooks of F. M. Dostoevsky (preserved in the Manuscripts Department of the Russian State Library, fund 93.I.2.8 and in the Russian State Archive of Literature and Arts, fund 212.1.4, 212.1.5). Some of the notes have not been deciphered or have a controversial reading in research literature. These include both the names of people with whom Dostoevsky personally communicated, the names of the authors of books that the writer read, and the anthroponyms of literary heroes. Proceeding from the commentaries that accompany the first publications of notebooks in vol. 83 of the “Literary Heritage” series, as well as in vols. 20 and 27 of “The Complete Works” of the writer in 30 volumes, the author of the article offers an updated and/or corrected commentary on certain names and titles. Thus, the correct title of the book by the historian I. D. Belyaev, which was a part of Dostoevsky’s library, and about which a memo was made, is established. Dostoevsky often left critical notes in his notebooks regarding the works of a particular contemporary. The article examines a number of entries about “nihilistic novels” instigated by the reading of the then-current works on female emancipation. The commentary by T. I. Ornatskaya, who ascribes the name “Lilinka” and the records associated with it to “Dream,” a short story by A. V. Korvin-Krukovskaya, is disputed, confirming the opinion of other researchers that the source of the records is N. D. Akhsharumov's novel “A Tricky Business.” The article also analyzes records concerning the writer's debts (for example, to V. P. Polyakov, P. A. Popov and V. P. Popov), as well as notes about the failed and unknown authors of the “Epoch” (a certain Andreev). In Dostoevsky's notebooks of the “Time” (“Vremya”) and “Epoch” (“Epokha”) period (1860–1865) there are proper names that still have no corresponding comments. The article aims to draw the attention of researchers to existing problems for further development of the topic.
