Arsenic(V) Immobilization in Fly Ash and Lead-Zinc Mine Tailing-based Geopolymer: Performance and Mechanism Insight
Authors: Bah Alseny , Jin Jie , Ramos Andrea , Li Feihu
Published: February 2022

Global mining activities produce thousands of millions of toxic-bearing mine tailing (MT) wastes each year. Storage of the mine tailings not only encroaches upon large areas of cropland but also arouses additional ecological and environmental risks especially when the toxics (e.g., arsenic) are leached out during the stormy weather. Herein we demonstrate that geopolymerization of a mixture of the toxic-bearing mine tailings and the coal fly ash (FA) with a blending of sodium hydroxide (NaOH) and sodium silicate solution can effectively immobilize extra arsenic (As) species derived from arsenic-bearing wastes in the geopolymer specimens, which also possess high compressive strengths (e.g., > 25 MPa for specimens with 54 wt.% FA and activated with 10 M NaOH), allowing them to be further used as low-carbon, cement-free building materials. The geopolymer strength was found to depend clearly upon the NaOH concentration, the fly ash content, the arsenic content, and the curing time, with the maximum being 37.07 MPa for a specimen with 54 wt.% FA, 0.03 wt.% As activated with 10 M NaOH and cured for 28 days. Leaching tests showed that all specimens can achieve an immobilization efficiency as high as 95.4% toward As, and that the leachabilities of both As and other toxic heavy metals are far below the limits of the Chinese leaching standard for hazardous wastes (GB 5085.3 − 2007). Microstructural analyses using X-ray diffractometer (XRD), scanning electron microscopic (SEM), Fourier transform infrared (FTIR) indicate that the As species was physically encapsulated along with the formation of geopolymer gels at first, and then chemically incorporated into the crystalline phases (e.g., calcium silicate, and calcium silicate hydroxide) derived from the geopolymer gels as a result of prolonging the curing time. The developed FA/MT-based geopolymers represent a promising green material for both the remediation of As-bearing lands and the construction industry.
Nonequilibrium Regulation of Interfacial Chemistry for Dissipative Supramolecular Assembly of Macroscopic Hydrogels
Authors: Zhao Ting , E Yuyu , Cui Jiwei , Hao Jingcheng , Wang Xu
Published: February 2022

The nonequilibrium assembly in nature exists at the microscopic and macroscopic scales, and represents the most common way to regulate object motions by consuming chemical fuels. In artificial nonequilibrium systems, most of the work has focused on the microscopic dissipative assembly, whereas the investigation on nonequilibrium assembly of macroscopic building blocks is rarely reported. Here, we present an efficient strategy to dynamically mediate the interfacial chemistry of pH-responsive polyelectrolyte hydrogels, thereby regulating their macroscopic nonequilibrium assembly. The driving force for the assembly is the transient electrostatic attraction, which is regulated by the biocatalytic feedback-driven temporal programming of the pH of the system. The dissipative assembly process can be controlled by adjusting the hydrogel parameters and fuel composition and it can be repeated by refueling the system. Most importantly, the ordered sewing of complementary hydrogels promotes the precise nonequilibrium supramolecular assembly to yield transient macroscopic supramolecular devices potentially useful for timed release.
Impact of Nanoparticle Size and Surface Chemistry on Peptoid Self-Assembly
Authors: Monahan Madison , Homer Micaela , Zhang Shuai , Zheng Renyu , Chen Chun-Long , DeYoreo James , Cossairt Brandi
Published: February 2022

Self-assembled organic nanomaterials can be generated by bottom-up assembly pathways where the structure is controlled by the organic sequence and altered using pH, temperature, and solvation. In contrast, self-assembled structures based on inorganic nanoparticles typically rely on physical packing and drying effects to achieve uniform superlattices. By combining these two chemistries to access inorganic-organic nanostructures, we aim to understand the key factors that govern the assembly pathway and structural outcomes in hybrid systems. In this work, we outline two assembly regimes between quantum dots (QDs) and reversibly binding peptoids. These regimes can be accessed by changing the solubility and size of the hybrid monomer unit. The hybrid monomers are synthesized via ligand exchange, assembled, and studied using ex-situ transmission electron microscopy as a function of time. The QDs were found to stabilize certain morphologies of peptoid intermediates and generate a unique final product consisting of multilayers of small peptoid sheets linked by QDs. The QDs were also seen to facilitate or inhibit assembly in organic solvents based on the relative hydrophobicity of the surface ligands, which ultimately dictated the solubility of the hybrid monomer unit. Increasing the size of the QDs led to large hybrid sheets with regions of highly ordered square-packed QDs. A second, smaller QD species can also be integrated to create binary hybrid lattices. These results create a set of design principles for controlling the structure and structural evolution of hybrid peptoid-QD assemblies and contribute to the predictive synthesis of complex hybrid matter.

Published: February 2022

Aim. To determine the role of chronic cervicitis and violations of local immunity of the cervix in the etiology of miscarriage of the first trimester, as well as to justify the necessary scope of examination for timely therapeutic and preventive measures.
Materials and methods. The results of a prospective and retrospective study of 225 women with undeveloped pregnancy who were admitted to a gynecological hospital are presented. All women received microscopic, cultural, and molecular genetic (PCR), studies of vaginal and cervical canal discharge, cytological studies of scrapings from the cervical canal and cervix, studies of the structure of cervical mucus and its immunoglobulin A, and pathomorphological studies of the fetal egg. According to the results of the pathomorphological examination of the abortion material in combination with the clinical data, the examined patients were divided into 2 groups. Group 1 included 95 women with bacterial infection of the fetal egg, group 2 90 women with viral infection of the fetal egg. As a control group, 40 women with normal progressive pregnancy were taken, who were admitted for its artificial termination.
Results. Inflammatory diseases of the lower genital organs in the group of women with bacterial infection of the fetal egg are significantly more common than in the group of viral infection of the fetal egg and the control group, and correlate with the results of pathomorphological studies in more than 86.7% of cases. In the group of women with bacterial infection, according to the results of the study of the structure of cervical mucus and the level of secretory IgA, a decrease in local immunity of the cervix was revealed.
Conclusion. The analysis of the research results allows us to confirm the concept of ascending infection of the fetal egg in the bacterial etiology of undeveloped pregnancy, which deserves the practical attention of obstetricians and gynecologists and further study for the timely treatment of at hospital phase dysbiotic and inflammatory diseases of the lower parts of the female genital organs during pregravidar preparation.

Huge resources of the health system and economies of all countries of the world are devoted to combating the COVID-19 pandemic (Coronavirus disease 2019). It is important to formulate effective measures to prevent the spread of a new coronavirus infection and the development of its postcoid complications. For this, it is necessary to study in depth not only the etiopathogenesis, clinical manifestations of the disease, but also to assess the influence of another pathology on the course of the development of the disease. Particular attention should be paid to pregnant patients with COVID-19. To clarify the relationship between COVID-19 and iron deficiency anemia. The information material includes data from scientific articles available in Pubmed and Internet resources on this topic, as well as data from our own observations. Timely diagnosis and treatment of iron deficiency anemia in pregnant women helps not only to prevent the development of obstetric and perinatal complications, but also to prevent the development of a severe course of COVID-19.

Published: February 2022

Для выявления генетических патологий плода женщин на I триместре беременности проанализированы 456 результатов скрининга биохимических и ультразвуковых маркеров анеуплоидии, проведённого на базе клиники ООО «Медикал Геномикс» (г. Тверь). Самым распространённым заболеванием плода у обследованных являлся синдром Дауна (89% от всех выявленных возможных генетических аномалий развития эмбриона). Биохимические маркеры скрининга, такие как содержание хорионического гонадотропина (ХГЧ) и плацентарного фактора роста (PLGF) в крови матери, по нашим результатам являются более информативными, чем ультразвуковые для выявления вероятности развития синдрома Дауна у плода на ранней стадии беременности женщины.

To identify genetic pathologies of the fetus of women in the first trimester of pregnancy, 456 results of screening of biochemical and ultrasound markers of aneuploidy, carried out on the basis of the clinic of LLC "Medical Genomix" (Tver), were analyzed. The most common fetal disease in the examined patients was Down syndrome (89% of all identified possible genetic anomalies of embryo development). Biochemical markers of screening, such as the content of human chorionic gonadotropin (HCG) and placental growth factor (PLGF) in the mother's blood, according to our results, are more informative than ultrasound for detecting the likelihood of developing Down syndrome in a fetus at an early stage of a woman's pregnancy

A New Financial Stress Index for Ukraine
Authors:   National Bank of Ukraine, Filatov Vladyslav
Published: February 2022

This study improves on the methodology for calculating the financial stress index (FSI) for Ukraine by introducing a time-varying correlation into the aggregation of five subindices (representing the banking sector, households, the corporate sector, government securities, and the foreign exchange (FX) market). The index consists of 20 indicators selected from an initial list of 47 potential candidates. To check the performance of the indicators, subindices, and the index, we use the area under the receiver operating characteristic curve (AUROC) and logit tests. Each subindex is assigned a weight that reflects the impact of each market on the financial system. This new FSI peaks during periods of crisis that are in line with the consensus of financial experts and performs better than the previous FSI, which makes it more attractive for policy decisions. In particular, the new FSI can be used as a monitoring tool for the macroprudential policy of the National Bank of Ukraine.

El tema de la cultura organizacional como objeto de esta reflexión, se inte- resa por considerar sobre la necesidad de un modelo inclusivo para la Univer- sidad Nacional Mayor de San Marcos (UNMSM). Institución considerada como una de las más importantes y representativas del Perú. A través de un ejercicio investigativo de enfoque cualitativo con carácter exploratorio-diagnóstico, se hace la pregunta respecto al tipo de cultura organizacional y su relación con las necesidades académicas de los alumnos con discapacidad, especialmente la de tipo visual. A partir del modelo de Cultura Organizacional para el liderazgo de Edgar Schein se analiza la posibilidad de abordar prácticas inclusivas cuya perti- nencia haría posible la integración plena de los alumnos con discapacidad de la UNMSM a la vida académica. Se concluye que debe reestructurarse la cultura organizacional actual, pues esta es incongruente con un modelo inclusivo que contemple la diversidad sensorial.
Prensa y construcción nacional en 1886: Eliseo Payán o el boadbil del radicalismo colombiano

Luego de 46 años de libertad absoluta de Prensa durante los gobiernos del liberalismo radical, el país sufrió una profunda transformación política liderada por el presidente Rafael Núñez, que se materializó con la nueva Constitución en 1886 y que sentó las bases de un ordenamiento del Estado bajo gobiernos conservadores. La necesidad de sujetar su ejercicio y la libertad de expresión bajo la imposición de severas leyes de prensa originó procesos de resistencia, pero también una enorme proliferación de diarios especialmente en Bogotá. La prensa política sujeta a los delitos de injuria y calumnia, junto a la mirada inquisidora de la probable injerencia en la subversión del orden público, dan cuenta de la importancia que tuvo para los gobiernos de La Regeneración ajus- tar las leyes hacia los llamados delitos de imprenta. La ciencia histórica como fuente teórica y metodológica es una herramienta para visibilizar las tensiones surgidas entre los grupos políticos, cuya representación sistémica es avalada por el contraste crítico de fuentes primarias, y permite la generalización de los fenómenos sociales. En el caso del texto presentado, se analiza el tránsito de la prensa política bogotana hacia los límites de contenidos impuestos por la Constitución de 1886, con una mirada hacia los intereses colectivos amenaza- dos por la conflagración social, bajo los conceptos de identidad nacional y el control del Estado.

El presente artículo tiene como propósito mostrar las características de un subgénero de la literatura de terror, denominado por la crítica como terror filo- sófico. Así, se exponen las formas en las que este estilo, de la mano de su princi- pal exponente Thomas Ligotti, se nutre de las formulaciones clásicas del terror expuestas por Poe, las mezcla con las estructuras narrativas de Lovecraft e introduce postulados filosóficos de la mano de pensadores como Peter Wessel Zapfe, para adentrarse en un entramado narrativo que resulta novedoso para el lector culto del terror, y aun así, logra mantener una herencia de tradición histórica muy marcada en un contexto situacional que le permite profundizar mucho más en aspectos como la conciencia, la ciudad o el ejercicio del hombre como ciudadano. Este artículo nace como respuesta a la pregunta ¿qué carac- teriza la literatura del terror filosófico de Ligotti en el siglo XXI? propuesta por el grupo de investigación Litterae de la Universidad de Caldas.
Aproximación a La peste de Camus desde la propuesta semiótica de Joseph Courtés
Authors: Salgado Acosta Libia , Buitrago Osorio Luis Armando
Published: February 2022

Este artículo pretende mostrar la propuesta semiótica de Joseph Courtés, aplicada a la obra literaria La Peste de Albert Camus. Para alcanzar este objetivo nos centraremos, principalmente, en los tres niveles de análisis propuestos por Courtés en su obra Análisis semiótico del discurso, el nivel figurativo, el nivel temático y el nivel axiológico, que permiten que nos aproximemos a la obra desde tres enfoques; primero, a la representación figurativa que tenemos del fenómeno- la peste-, bien sea desde lo icónico o desde lo abstracto; segun- do, a lo temático que encierra la propuesta general del autor y que se puede traducir, en el caso de La Peste, en la pandemia ocurrida en Oran, escenario físico y sociocultural donde se desarrolló la historia; tercero, a lo axiológico que enfrenta al lector a los juicios de valor que asume ante las situaciones vividas por los personajes, y que permite una confrontación entre sus propios principios de lector con los valores morales de los habitantes de Orán, que se van transformando a medida que avanza la enfermedad. Parece como si fuera necesaria una situación extrema para que consideremos la importancia de pararnos a reflexionar, a mirar la vida con otros ojos, a enfrentarnos a ella con la sensibilidad de ayudarnos los unos a los otros.

This study aims to reveal stigma toward sex worker depicted in two literary texts i. e. a short story entitled “Boule de Suif” by Guy de Maupassant, a French writer and a short story entitled “Catatan Seorang Pelacur” by Putu Arya Tirtawirya, an Indonesian writer. The two short stories are chosen for the reason that both works depect the life of a female sex worker. This study is designed as a descriptive qualitative study with sociological approach. The sociological approach is applied because this study looks at society’s views on female sex workers tht is reflected in the short stories. Moreover, theories of stigma are reviewed to support the analysis. The Analysis is focused on the sex worker stigma, the manifestation of stigmatization against sex workers, how the female sex worker in each short story responds to the stigmatization, and whether authors of the short stories affirm or criticize their society.
THE STUDY OF BOURDIEU’S SYMBOLIC VIOLENCE IN ALEX URBAN’S “THE KINGFISHER SECRET”
Authors: Arifin Zainul
Published: February 2022

This study looks at symbolic violence in Alex Urban's novel The Kingfisher Secret. In Alex Urban's work The Kingfisher Secret, the author investigates the emergence of symbolic violence and analyzes Bourdieu's capital and habitus. To assist the understanding of symbolic violence, this research employs Pierre Bourdieu's symbolic violence idea, as well as habitus, field, and capital theory. This study employs Wellek and Warren's extrinsic method, in which literary material is examined from a social perspective. The author employs a descriptive qualitative technique to locate symbolic violence. The findings demonstrate that in Alex Urban's work The Kingfisher Secrets, symbolic violence is portrayed by offering a present (gift exchange), expressing compassion, delivering an order (indirect command), and respectfully declining. The habitus is brutally capitalistic, rationalizing any means and aspirations to improve one's life and circumstances. The agency uses symbolic violence to achieve its goals and gain dominance.
Diplomatie als soziale Institution. Brandenburgische, sächsische und kaiserliche Gesandte in Den Haag, 1648–1720
Authors: Legutke Daniel
Published: February 2022

Dem niederländischen Regierungssitz Den Haag kam durch die weit ausgreifende Politik der Republik zwischen den westfälischen Friedensschlüssen und den ersten beiden Jahrzehnten des 18. Jahrhunderts eine Schlüsselstellung im europäischen Gesandtschaftswesen zu. In den Kriegen, die auf die Epochenwende 1648 und 1659/60 folgten, wurde nicht mehr wie in den vorhergehenden Religionskriegen um die Existenz gerungen, sondern um die Aufrechterhaltung oder Wiederherstellung einer gedachten Machtbalance. Daraus erwuchs den Gesandten eine neue Aufgabenfülle und politische Rolle. Das blieb nicht ohne Wirkung auf die Gesandten, die Veränderungen nicht nur ertrugen, sondern zunehmend selbst gestaltend eingriffen. Diese dynamischen Prozesse in der Arbeitsweise von Gesandten dreier Höfe am niederländischen Regierungssitz Den Haag stehen im Mittelpunkt der vorliegenden Arbeit. Indem aufgearbeitet wird, wie Den Haag von einem Treffpunkt von Gesandten zum Brennpunkt europäischer Diplomatie wurde, möchte die vorliegende Studie einen Beitrag zur Geschichte des Gesandtschaftswesens im frühneuzeitlichen Europa leisten.

Published: February 2022

The waste composition in Boyolali Regency consists of 37.13% garden waste. The waste can be treated with a thermal process so that it can be reused for energy. The method of sorting waste with thermal technology consists of various types adapted to the gods. This study aimed to evaluate the most co-cog heat treatment processes for waste processing in Boyolali Regency. The determination process is carried out using a literature review, while the selection process uses the Analytical Hierarchy Process (AHP) method. The alternatives given in this research are carbonization, pyrolysis, and synergy processes. In the alternative selection, there are three criteria, namely mass balance, CO2 residue, and energy volatility. In terms of mass balance, the waste that the carbonization process can treat tends to be higher than that of the pyrolysis and incineration processes. Meanwhile, the carbonization process is better than pyrolysis and carbonization for wood waste for emission and energy requirements. The result of AHP shows that the carbonization process is suitable to be applied in Boyolali Regency. However, it is necessary to conduct further studies on non-technical aspects to strengthen alternative election results.

Published: February 2022

Covid-19 is a new type of corona virus called SARS-CoV-2. One of the cities that has contributed the most to infected Covid-19 cases in Indonesia is Surabaya, East Java. Predicting the Covid-19 is the important thing to do. One of the prediction methods is Artificial Neural Network (ANN). The backpropagation algorithm is one of the ANN methods that has been successfully used in various fields. However, the performance of backpropagation is depended on the architecture and optimization method. The standard backpropagation algorithm is optimized by gradient descent method. The Broyden - Fletcher - Goldfarb - Shanno (BFGS) algorithm works faster then gradient descent. This paper was predicting the Covid-19 cases in Surabaya using backpropagation with BFGS. Several scenarios of backpropagation parameters were also tested to produce optimal performance. The proposed method gives better results with a faster convergence then the standard backpropagation algorithm for predicting the Covid-19 cases in Surabaya.

Orange is a type of fruit that is easily found in Sambas Regency. The types that are widely sold are Siam oranges, madu susu and susu. Each type of orange has a different quality and a different price. The price difference often results in fraud committed by traders against buyers to the detriment of the buyer. This is because differentiating types of oranges based on the appearance of the fruit does not have a standard. Therefore, in this study, a citrus fruit classification system was created based on images by implementing deep learning. The method of deep learning used in this research is Convolutional Neural Network (CNN) with AlexNet architecture. The types of oranges that will be observed are madu oranges, madu susu, and siam. The data used are 2250 images of oranges with each class totaling 750 images with a size of 227x227 pixels. The training data is 1575 images and the test data is 675 images. The training is carried out with a total of 10 epochs and each epoch will produce a model. System testing is carried out based on the model generated in the training process. Each model will be observed results in the form of accuracy which is calculated using a confusion matrix. The most optimal model was generated from training in epoch the 9th which resulted in an accuracy of 94.81%.

Recurrent Neural Network With Gate Recurrent Unit For Stock Price Prediction
Authors: Caniago Afif Ilham , Kaswidjanti Wilis , Juwairiah Juwairiah
Published: February 2022

Stock price prediction is a solution to reduce the risk of loss from investing in stocks go public. Although stock prices can be analyzed by stock experts, this analysis is analytical bias. Recurrent Neural Network (RNN) is a machine learning algorithm that can predict a time series data, non-linear data and non-stationary. However, RNNs have a vanishing gradient problem when dealing with long memory dependencies. The Gate Recurrent Unit (GRU) has the ability to handle long memory dependency data. In this study, researchers will evaluate the parameters of the RNN-GRU architecture that affect predictions with MAE, RMSE, DA, and MAPE as benchmarks. The architectural parameters tested are the number of units/neurons, hidden layers (Shallow and Stacked) and input data (Chartist and TA). The best number of units/neurons is not the same in all predicted cases. The best architecture of RNN-GRU is Stacked. The best input data is TA. Stock price predictions with RNN-GRU have different performance depending on how far the model predicts and the company's liquidity. The error value in this study (MAE, RMSE, MAPE) constantly increases as the label range increases. In this study, there are six data on stock prices with different companies. Liquid companies have a lower error value than non-liquid companies.

ASSESSMENT OF THE WIND FARM IMPACT ON POWER SYSTEM STABILITY WHILE REDUCING OF TOTAL INERTIA
Authors:   National Research Tomsk State University, Tomsk, Russia, Razzhivin I.A.
Published: February 2022

With the development of wind power in the world, the issues of joint operation of wind power plants in power systems become relevant. Modern variable speed wind turbines with are connected to the network through power voltage converters, which, with their significant integration into the power systems, negatively affects the transient stability of such systems, the operation of emergency control devices, etc. The problem is caused by the effect of "decoupling" of the wind turbine generators from the power systems, since the connection of the mechanical moment of the wind turbine with the power system is lost, its frequency characteristics also change, the overall inertia of the system decreases, and as a consequence, these phenomena can lead to rapid fluctuations in frequency and voltage in normal modes, and also an avalanche of frequency and voltage in case of accidents. In addition, a decrease in the total inertia can contribute to the failure of out-of-step protection systems for eliminating the out-of-step mode, due to an increase in the slip frequency. In the article, experimental studies of the implementation of wind power plants in power system to assess the impact of their work on the rate of the transients.
A novel two-layer, intradural and extradural patch graft approach to treating dural defects and tears: illustrative case
Authors: Lazarus Daniella , Hawks Charlotte , Kumar Namrita , McCaffrey Tara , Jenkins Arthur L.
Published: February 2022

BACKGROUND

Dural tears must be quickly addressed to avoid the development of positional headaches and pseudomeningoceles, among other complications. However, sizeable areas of friable or absent dura create unique challenges when attempting to achieve a watertight seal. We have developed a two-layer subdural and epidural fibrous patch technique to treat expansive or challenging dural tears as a result of our experience treating spinal fluid leaks.

OBSERVATIONS

The authors present the treatment of a large necrotic (5 × 1.5 cm) dural defect refractory to initial attempts at standard primary repair with dural patch grafting and requiring a revision with a dual-layer patch to manage persistent cerebrospinal fluid leakage.

LESSONS

The use of a two-layer (subdural and epidural) patch is both a safe and effective dural repair technique for creating a watertight seal in challenging large areas in which the dura may be damaged, scarred, or absent. We also propose that this technique may be able to be used for smaller challenging tears, as well as potentially for repairs of large blood vessels or other fluid-filled structures in the body.
Maltrato infantil y trastorno mental

Published: February 2022

La infancia constituye el periodo más prolongado y sensible en la vida de los seres humanos. En los principios de nuestra especie, la supervivencia de los recién nacidos y de los niños estuvo íntimamente ligada a las habilidades de sus progenitores y de su pequeño grupo social para garantizar su seguridad. Que los niños sobrevivieran y llegaran a la adolescencia para poder transmitir los genes de sus padres a una nueva generación, era una cuestión esencial para la continuidad de la especie. Resulta sencillo pensar, por tanto, hasta qué punto los vínculos afectivos y las habilidades para desarrollar estrategias de protección por parte de los adultos hacia sus niños fueron seleccionadas por la evolución como funciones mentales humanas esenciales y características de nuestra especie.
