Autoridade e política: a gestação do conceito de ditadura em Donoso Cortès e sua recepção por Schmitt
Authors: Bueno Roberto
Published: November 2021

O objeto deste artigo é analisar se os conceitos de autoridade e política forjados pelo conservadorismo contrarrevolucionário de Donoso Cortés no século XIX puderam contribuir para o desenvolvimento do conceito de ditadura no século XX com Schmitt. Foram realizadas aproximações conceituais específicas entre a ditadura, a concepção de autoridade fundamentalmente por intermédio de duas vias conectivas, a saber, a fundamentação teológica destes conceitos e, por outro lado, o recurso ao conservadorismo de maistreano objetivando a ampliação o conhecimento sobre a gramática conservadora nesta matéria. Este artigo problematiza a teoria da ditadura de Donoso com a especial preocupação de delinear alguns de seus pontos de partida estendendo algumas vias hermenêuticas que permitam ampliar a linha compreensiva do sentido que a violência e o político aportam na reflexão filosófico-política de Donoso Cortés em face da excepcionalidade. Voltar a estes problemas fundamentais da filosofia política contribui de modo relevante para o desenho de novos quadros interpretativos da realidade política. Fazê-lo desde as linhas de Donoso Cortés apresenta a vantagem adicional de apresentar autor apenas parcialmente conhecido no Brasil, mas que, paralelamente, é fonte de seu conservadorismo.

Por ﬁ m, nós tentamos reﬂetir sobre uma tradicional aproximação que se tem feito entre Nietzsche e Kant no que diz respeito ao âmbito moral.
Natureza e política: uma tensão no pensamento de Michel Foucault
Authors: Raffin Marcelo
Published: November 2021

Este artigo procura desenvolver a relação entre natureza e política no pensamento de Michel Foucault como a produção do “humano” ou do vivente “humano” a partir da especial imbricação que o filósofo propõe entre vida e poder mediante três noções centrais de sua produção: as da biopolítica, da correlação entre práticas sociais de encerro, novos domínios de saber, novos objetos e novos sujeitos, da qual se produziria a subjetividade moderna e toda a ordem social moderna como sociedade de normalização, e da constituição da figura do “homem” no interstício da positividade das ciências que se criaram em torno dela.
POR UMA REVISÃO TEÓRICA DA PSIQUE EM ARISTÓTELES: UM ENSAIO EPISTÊMICO-FILOSÓFICO PARA UMA PSICOLOGIA COMPLEXA DO SÉCULO XXI
Authors: Correio Fabiana , Correio Simone
Published: November 2021

Esse ensaio investigou a concepção epistêmica da psique aristotélica em contraponto a visão de Descartes na Modernidade para fomentar uma superação dos projetos psicológicos modernos que partiam em sua grande maioria do projeto cartesiano, no qual a psique  é compreendida como consciência. Essa matriz cartesiana tem demarcado um modo de se fazer e de se pensar o fenômeno psicológico de forma dicotômica, separando mente e corpo, assim como tornando o fenômeno psicológico um ente naturalizado e universal. Nesse sentido, a concepção de psique Aristotélica pode trazer um contraponto a essas escolas psicológicas de base cartesiana, pois, concebem o psiquismo, não como consciência, mas como vida, sendo que um dos momentos da vida é a consciência, mas não o único, como ocorre com a visão cartesiana.

Desconstruir a Corrupção: o Papel do Legislador, Príncipe e Soberano. A Análise do Caso no Pensamento de Jean-Jacques Rousseau
Authors: Medeiros Martins Adriano Eurípedes
Published: November 2021

Não há Estado sem os indivíduos. Para Rousseau a construção do Estado requer a participação direta dos cidadãos. A participação ativa dos cidadãos resultará na expressão da vontade geral. É a vontade geral que, via pacto social, dará vida e união ao Estado. O Estado é um projeto de corpo político. A participação ativa dos cidadãos com vistas a impedir a corrupção e a dissolução da sociedade remete à concepção da soberania popular. Nessa modalidade de soberania, os cidadãos seriam capazes de construir e manter os fundamentos da sociedade civil. Rousseau, como um contratualista, pensa a sua época e as soluções políticas para os problemas reais de seu tempo. Portanto, é desse cenário entre a teoria e a prática, que Rousseau partirá para configurar a distinção e a relação desse importante tripé: soberano, Legislador e príncipe.
El Estado terrorista y la nuda vida. El caso de la dictadura cívico-militar argentina (1976-1983)
Authors: Micieli Cristina
Published: November 2021

En este artículo analizamos la dictadura cívico-militar argentina (1976-1983) bajo la óptica de la biopolítica y de la ontología derrideana, rastreando las formas ]en las que la política inaugurada en 1976 y la violencia llevada a cabo se superponen y se enmascaran, y la manera cómo, en su reverso, aparecen las denominadas “figuras de la persecución”. El Estado de excepción, bajo la dictadura, dio lugar a un Estado de seguridad. El recurso al estado de excepción/seguridad en tanto Estado vacío de derecho, y la búsqueda de una nueva legalidad para construir una legitimidad que no se poseía son puntos analizados en este artículo. Asimismo, la contigüidad entre FF. AA./golpistas y función de policía tiene como consecuencia la criminalización del adversario. Por su parte, al colocarse por encima de la ley al instituir un estado de excepción, el nuevo soberano asume la figura de la bestia, en la conceptualización de Derrida, la cual también se coloca por fuera de ley al transgredirla. Palabras-clave: Estado de excepción; Violencia; Nuda Vida; Bestia/Soberanía.

Published: November 2021

Neste artigo, buscaremos colocar em relação Levinas e Kant, pondo-se a seguinte questão: qual é a fonte da moralidade? Em outras palavras: quem é responsável? Para fins de clareza metodológica o texto será dividido em três partes nas quais internamente tomaremos para reflexão o exame da Fundação a metafísica dos Costumes (Grundlegung zur Metaphysik der Sitten) de Kant e Humanismo do outro Homem (Humanisme de l’autre homme) de Levinas. Estas obras nos permitirão apresentar as ideias para um possível ligame entre os dois pensadores. Procuraremos mais exatamente refletir, por uma parte, como Kant funda a moralidade; e por outra, como realiza-se a passagem da intencionalidade ao ético em Levinas.
Ética e Bioética: O Princípio da Justiça na Transição para uma Sociedade mais Justa a partir de uma Educação Transformadora

A questão central de nossa proposta é mostrar a possibilidade e viabilidade de manter uma reflexão ético-bioética, a partir do princípio de justiça, para promover uma educação de qualidade que prima pela transformação da sociedade e pela manutenção da ética na política, na economia, na sociedade em geral e, principalmente, na família como mantenedora da ordem moral pessoal e social. Ética e justiça caminham juntas na formação do homem virtuoso e de consciência crítica e cidadã. Por isso mesmo, destacamos I. Kant e J. Raws a partir da análise de O. Pergoraro sobre ética e justiça, considerando a necessidade de implementar uma visão de uma sociedade mais justa a partir de uma educação para o despertar da consciência democrática e cidadã para o cumprimento dos direitos e deveres da pessoa humana digna e contemplando uma sociedade onde as liberdades sejam respeitadas e valoradas.
Heavy metal-free visible-to-UV photon upconversion with over 20% efficiency sensitized by a ketocoumarin derivative
Authors: Uji Masanori , Harada Naoyuki , Kimizuka Nobuo , Yanai Nobuhiro
Published: November 2021

Efficient triplet-triplet annihilation-based photon upconversion (TTA-UC) from visible to UV light without using heavy metals is still a challenging task. Here we achieve a record-high TTA-UC efficiency of 20.3% among 100% maximum by employing a ketocoumarin derivative as a triplet sensitizer, which shows strong visible absorption, weak UV absorption, and efficient intersystem crossing.
Solvent vapor annealing for controlled pore expansion of block copolymer-assembled inorganic mesoporous films
Authors: Alvarez-Fernandez Alberto , Jara Fornerod Maximiliano , Reid Barry , Guldin Stefan
Published: November 2021

Mesoporous inorganic thin films are promising materials architectures for a variety of high-value applications, ranging from optical coatings and purification membranes to sensing and energy storage devices. Having precise control over the structural parameters of the porous network is crucial for expanding their applicability. To this end, the use of block copolymers (BCP) as sacrificial structure-directing agents via micelle co-assembly is a particularly attractive route, since the resultant pore size is directly related to scaling laws for the radius of gyration of the pore-forming macromolecule. However, tailoring the molecular weight of the BCP via bespoke synthesis is an elaborate process that requires precise control over highly sensitive reactions conditions. Alternative methods have emerged, based on supramolecular assembly or the addition of different swelling agents, but, to-date, these present a negative impact on the structural order and pore size dispersity of the final inorganic mesoporous films. In this work, we propose a novel and effective method for control over pore size, porosity and structural order, which relies on a synergistic combination of BCP selective swelling via solvent vapor annealing (SVA) and locking of the structure by condensation of the inorganic sol-gel precursors. The results obtained in this work for TiO2 establish SVA as a new, straightforward, simple, and powerful route efor the fabrication of mesoporous thin-film materials with controllable structural characteristics.
Enabling Tunable Hydrophilicity of PDMS via Metal-ligand Coordinated Dynamic Networks
Authors: Zhang Xinyue , Crisci Ralph , Finlay John. A , Cai Hongyi , Clare Anthony S. , Chen Zhan , Silberstein Meredith N.
Published: November 2021

Polydimethylsiloxane (PDMS) has been widely used in various fields due to its appealing physical and chemical properties. However, its high hydrophobicity not only yields poor adhesion to substrates but also facilitates undesired adsorption of substances such as proteins, biofoulers, etc., which limits the performance and lifetime of PDMS. Moreover, traditional surface modification techniques are often not efficient on PDMS surfaces because of the surface reconstruction. Although new methods involving chemical modification have been developed, most of them require complicated procedures and equipment. To overcome this challenge, we incorporate metal-ligand coordination, a non-covalent interaction bearing polar functionality, into PDMS, which exposes the hydrophilicity progressively upon dynamic bond breakage and reformation. We demonstrate that the hydrophilicity of coordinated PDMS can be tailored by the choice of network structure, counter anions, and metal cations, which yield distinct network dynamics. The wetting mechanism is discussed in the context of chain reconfiguration and surface reconstruction. We also show that a properly designed metal-ligand coordinated PDMS has potential as a superior marine fouling release coating by weakening diatom attachment. Through this paper, we introduce a new concept for tuning material hydrophilicity via dynamic polar functionalities, which is applicable to a wide range of polymers.
Improving force field accuracy by training against condensed phase mixture properties
Authors: Boothroyd Simon , Madin Owen , Mobley David , Wang Lee-Ping , Chodera John , Shirts Michael
Published: November 2021

Developing a sufficiently accurate classical force field representation of molecules is key to realizing the full potential of molecular simulation as a route to gaining fundamental insight into a broad spectrum of chemical and biological phenomena. This is only possible, however, if the many complex interactions between molecules of different species in the system are accurately captured by the model. Historically, the intermolecular van der Waals (vdW) interactions have primarily been trained against densities and enthalpies of vaporization of pure (single-component) systems, with occasional usage of hydration free energies. In this study, we demonstrate how including physical property data of binary mixtures can better inform these parameters, encoding more information about the underlying physics of the system in complex chemical mixtures. To demonstrate this, we re-train a select number of the Lennard-Jones parameters describing the vdW interactions of the OpenFF 1.0.0 (Parsley) fixed charge force field against training sets composed of densities and enthalpies of mixing for binary liquid mixtures as well as densities and enthalpies of vaporization of pure liquid systems, and assess the performance of each of these combinations. We show that retraining against the mixture data almost universally improves the force field's ability to reproduce both pure and mixture properties, reducing some systematic errors that exist when training vdW interactions against properties of pure systems only.
Ni@C Catalyzed Hydrogenation of Acetophenone to Phenylethanol under Industrial Mild Conditions in Flow Reactor
Authors: Lin Shanshan , liu Jianguo , Ma Longlong
Published: November 2021

The catalytic hydrogenation of organic substrates containing many unsaturated functional groups is an important step in the industrial preparation of fine chemicals and has always been a hot spot in basic catalysis research. For example, the phenethyl alcohol obtained by the preferential hydrogenation of the C=O group of acetophenone is a valuable intermediate for the production of spices, flavors, and medicines. Furthermore, as the demand for 1-phenylethanol (PhE) continues to increase, the catalytic hydrogenation of acetophenone (AP) is becoming more and more important. The hydrogenation of acetophenone is a complex multi-step reaction. At present, relatively few catalytic systems are used in this reaction. The enantioselective hydrogenation on heterogeneous catalysts is due to its inherent operational and economic advantages, such as the atomic economy. It is one of the most ideal methods as it is easy to separate and recycle the catalyst. However, the traditional synthesis way in batch reactors usually takes a long time with an unsatisfying conversion which is not conducive to industrialization. Heterogeneous non-precious metal catalysts are advantageous for their implementation in flow reactor systems for industrial applications due to their ease of separation, low cost, and environmental protection. Herein, we report the first use of non-noble metal Ni-supported graphene-based catalysts for hydrogenation of acetophenone to phenylethanol with high efficiency in the flow reactor which can significantly improve mass and heat transfer. The conversion rate after optimizing the reaction conditions can be as high as 99.14% with a satisfactory conversion rate of 97.77%. This catalyst is magnetic and has good cyclability. After 48 hours of uninterrupted continuous experiments, the Ni-based catalyst still maintains high catalytic activity, the conversion rate still reaches 88.44%, and the catalyst structure remains intact and stable.
Pushing and pulling on OH- and H3O+ with electric fields across water’s surface

Published: November 2021

We use second harmonic generation (SHG) spectroscopy, molecular dynamics simulation, and theoretical modeling to study the response of the neat liquid water-air interface to changes in the potential of an external electrode positioned above the liquid. We observe a parabolic dependence of second harmonic intensity on applied potential. This dependence is reminiscent of bulk-phase electric field induced second harmonic (EFISH) but more complicated because it combines the second-order response of the topmost water layer and the potential dependent response of the interfacial electrical double-layer. Based on the literature values for these contributions, we derive a physical interpretation of our measurements that reveals new insight into the response of the neat water interface to external electric fields. Specifically, we find that the net dipolar orientation of water molecules within the double-layer is primarily responsive to the internal fields generated by the excess surface concentrations of OH- and H3O+ that arise to screen the external potential. Notably, this interpretation implies that the orientational response of water dipoles at the interface can actually oppose the direction of the external field, a subtle effect that is not captured by traditional models.

Published: November 2021

El mastuerzo (Tropaeolum majus L.) es una planta originaria de Perú, México y partes de América Central; en el Perú, era usada desde tiempos muy antiguos, por nuestros antepasados, para combatir distintas enfermedades. Entre sus componentes se encuentra la glucotropaeolina, que, al ser hidrolizado, forma el bencil isotiocianato (BIT) que fomenta la apoptosis celular. Debido a ello, se tuvo como objetivo; primero, evaluar el efecto citotóxico del isotiocianato de bencilo del mastuerzo expuestas a microgravedad sobre el cultivo in vitro de la línea tumoral MCF-7 de cáncer de mama. Se utilizaron extractos de isotiocianato de bencilo de mastuerzo de la planta cultivada en forma natural (T1) y; la segunda, expuesta a microgravedad en la etapa de germinación (T2), comparándose con el producto comercial (BI), la viabilidad celular se efectuó a través de la técnica del MTT realizándose diluciones de 0, 20, 40, 60, 80 y 100 uM del extracto expuesto al cultivo de células tumorales de tipo MCF-7 cáncer de mama por un tiempo de 12, 24, 48, y 60 horas lecturándose en un lector de placas de ELISA a 570 nm. Se obtuvo una DL50 entre 22,56 ± 3,24 a 19,97 ± 2,52 a las 60 horas, valores similares a las 48 horas comparadas con el control benzil de isiocianato (BI). En conclusión, no se evidencia diferencia en el efecto de la dosis letal media de todos los tratamientos en las 48 y 60 horas de incubación frente al benzil isiocianato (BI). El efecto máximo de inhibición en todas las concentraciones es apreciable a las 60 horas de incubación, afirmándose que no existe una diferencia significativa de sus actividades biológicas entre T1 y T2.

Published: November 2021

Los efluentes de la industria pesquera tienen alta concentración de materia orgánica y nitrogenada; su descarga a los cuerpos acuáticos, afecta a la fauna presente en estos ecosistemas. La nitrificación es un proceso biológico que oxida el amonio a nitrato, luego este nitrato puede ser transformado a nitrógeno molecular mediante otro proceso biológico, la desnitrificación. En el presente trabajo, se ha estudiado un sistema combinado desnitrificante-nitrificante cuya configuración ha consistido de un reactor anóxico de filtro y un reactor aerobio de lodo activado. La alimentación de materia orgánica y nitrogenada fue de 1025 mg COT/L y 660 mg N-NH4+ respectivamente, valores promedios obtenidos en el efluente del reactor anaerobio utilizado como primera etapa de tratamiento de las aguas residuales de la industria pesquera. Se ha formulado un modelo matemático para el sistema combinado, basado en balances de masa y expresiones cinéticas. Las predicciones del modelo se compararon con los resultados experimentales, donde se evaluaron la eficiencia de remoción de materia orgánica y nitrógeno al modificarse la razón de recirculación. El sistema combinado ha operado con diferentes razones de recirculación. Al aumentar la razón de recirculación hasta un valor de 1.25, la eficiencia de remoción de materia orgánica y nitrógeno se mantuvieron constante. Para una razón de recirculación de 0.7, donde se alcanza una velocidad de carga orgánica y nitrogenada de 0.42 y 0.48 kg/m3*d, y una razón COT/N-NH4+ de 1, se logra una eficiencia de remoción de carbono orgánico y nitrógeno de 95 % y 80 %, respectivamente. Sin embargo, al aumentar la recirculación hasta 2.35, la eficiencia de remoción de amonio baja drásticamente hasta niveles inferiores a 50 %; en cambio, la eficiencia de remoción de carbono orgánico se mantiene sobre 80 %. El resultado muestra que con una razón de recirculación hasta 0.7 se logra una remoción simultánea de carbono orgánico y nitrógeno. El modelo predice adecuadamente el comportamiento del sistema.

Developing Statistical Modellings to Investigate the Internal Drivers for the Trend of Output Values in the Manufacturing Industry: Evidence from Chinese Enterprises
Authors: Zhang Yuzhou , Gao Guang , Shou Lidan , Wu Dun , Fang Guangping , Sun Hua
Published: November 2021

The manufacturing industry is an important pillar of the national economy. It is of vital importance to develop statistical modellings in order to quantify the relationship between potential internal drivers and the trend of output values in the manufacturing industry. However, only a few statistical modellings have been established to investigate such associations. This study developed the correlation coefficient model and generalized linear model (GLM) to measure the single and interactive effects of the internal drivers on the changes of the output values. For the GLM, different predictive variables were developed to fit into the dataset, and the performance of the models were compared using fitness parameters. Furthermore, an industry survey dataset for 1,180 manufacturing enterprises in 2020 was used to validate the models. The use of the GLM combining land area, number of employees, scientific research input, and labor productivity may have a great potential to bolster capacity in monitoring and predicting the trend of output values in the manufacture industry.
Pairs Trading Strategy for A and H Shares Based on Kalman-HMM Approach
Authors: Zang Ming
Published: November 2021

Pairs trading is a statistical arbitrage strategy that takes advantage of unbalanced financial markets. A common difficulty for quantitative trading participants is the detection of market institutional changes in financial markets. In order to solve this issue, the hidden Markov model (HMM) is applied for status detection. The research objective is to use Kalman filter to predict and the hidden Markov model (HMM) to identify state transitions on the basis of screening transaction pairs with obvious co-integration relationship. This research would prove the profitability of the strategy and the ability to resist risk through the combination of these two methods with real data. The empirical results showed that compared with the traditional cointegration strategy, the holding yield increased from 1.6% to 16.2% and the maximum pullback reduced to 0.02%. Further research is required to improve trading rules.
An Analysis of Government Interventions in Addressing Market Failures Caused by Non-Excludable and Non-Rivalrous Public Goods Based on COVID-19 Vaccination Cases
Authors: Chen Wenqing
Published: November 2021

The non-excludable and non-rivalrous characteristics of public goods distinguish them from private goods. The existence of these two characteristics leads to the “free rider problem” and the variation problem, making the market supply less than the actual demand, thus causing market failure. The government should therefore intervene against this impact. At the beginning of 2020, the global outbreak of the novel COVID-19 brought significant harm to various countries, races, and groups of people. In the second half of 2020, several companies developed vaccines, which are able to fundamentally block the transmission of the virus. However, as vaccines have been reducing the severity of the epidemic in certain regions, the situation somewhat reflects non-excludability and non-rivalry, in which before officially being listed in vaccination programs, the society may have the thought of “vaccination would reduce the risk of transmission; thus, I can enjoy the reduced risk of everyone being vaccinated without paying for it.” For this reason, most countries have been purchasing vaccines for the public through government appropriations to solve the free-rider problem. It can be said that in the face of market failure caused by public goods, the government should carry out timely intervention measures, including taxation and government appropriation, to avoid negative impacts from the characteristics of public goods.

Published: November 2021

The economic growth pattern in China is changing from high-speed development to high-quality development. In order to promote high-quality economic development, it is necessary to promote the transformation and upgrading of all aspects of social reproduction. Artificial intelligence has promoted high-quality economic development in China from the aspects of innovation effect, technology spillover effect, factor improvement effect, and technology optimization effect. However, there are still several problems in China’s AI development, such as the lack of core technologies, privacy and security, as well as the lack of high-tech talents. To this end, China should advance basic theoretical research and key generic technology development to improve the self-reliance of science and technology, as well as optimize the development environment of the industry and improve the relevant laws and regulations as well as the ethical norms system. A system to train high-quality personnel and a mechanism that allows personnel flow should be established to promote high-quality economic development.

The purpose of this study was to empirically examine the effect of transformational leadership and human resources training on employee well-being with organizational justice as a mediating variable. This study used purposive sampling. The sample consisted of 54 respondents who were employees, and the research data were analyzed using the SmartPLS version 3.3.2 software program. The results of this study indicated that transformational leadership and human resources training at the company have a significant and positive effect on employee well-being. This means that the better the transformational leadership is realized in the company, the higher the employee well-being in the company. However, based on the research results, organizational justice did not have a significant and negative effect on employee well-being. So that organizational justice cannot mediate the relationship between transformational leadership and human resources training for employee well-being. The implication of this research for companies in general is that companies can maintain and improve their employee well-being. Suggestions for the company, it is hoped that it can maintain and improve transformational leadership and conduct human resources training regularly and with good procedures to improve employee well-being in a company, because human capital is the one of the main capitals that it is important to be managed by the company.

escuela y la cárcel: ¿fracaso de la prisión y crisis de la escuela?
Authors: Saldarriaga Vélez Óscar
Published: November 2021

El artículo recorre el problema de las analogías y diferencias entre la prisión y la escuela, un tema agitado desde la década de 1980 en el seno del Movimiento Pedagógico Colombiano, a la luz de ciertas apropiaciones del libro Vigilar y castigar de Michel Foucault. En la segunda parte el texto recoge la tesis foucaultiana sobre el “fracaso de la prisión” (“el fracaso hace parte del funcionamiento del dispositivo disciplinario”) y propone analizar este “fracaso” en el caso de la escuela moderna, a partir de análisis desarrollados en el marco de los trabajos del Grupo de Historia de la Práctica Pedagógica en Colombia.
A Comparison of Machine Learning Approaches for Prediction of Permeability using Well Log Data in the Hydrocarbon Reservoirs
Authors: Talebkeikhah Mohsen , Sadeghtabaghi Zahra , Shabani Mehdi
Published: November 2021

Permeability is a vital parameter in reservoir engineering that affects production directly. Since this parameter's significance is obvious, finding a way for accurate determination of permeability is essential as well. In this paper, the permeability of two notable carbonate reservoirs (Ilam and Sarvak) in the southwest of Iran was predicted by several different methods, and the level of accuracy in all models was compared. For this purpose, Multi-Layer Perceptron Neural Network (MLP), Radial Basis Function Neural Network (RBF), Support Vector Regression (SVR), decision tree (DT), and random forest (RF) methods were chosen. The full set of real well-logging data was investigated by random forest, and five of them were selected as the potent variables. Depth, Computed gamma-ray log (CGR), Spectral gamma-ray log (SGR), Neutron porosity log (NPHI), and density log (RHOB) were considered efficacious variables and used as input data, while permeability was considered output. It should be noted that permeability values are derived from core analysis. Statistical parameters like the coefficient of determination ( ), root mean square error (RMSE) and standard deviation (SD) were determined for the train, test, and total sets. Based on statistical and graphical results, the SVM and DT models perform more accurately than others. RMSE, SD and R2values of SVM and DT models are 0.38, 1.63, 0.97 and 0.44, 2.89, and 0.96 respectively. The results of the best-proposed models of this paper were then compared with the outcome of the empirical equation for permeability prediction. The comparison indicates that artificial intelligence methods perform more accurately than traditional methods for permeability estimation, such as proposed equations. Doi: 10.28991/HEF-2021-02-02-01 Full Text: PDF

Published: November 2021

Introduction:
The preoperative correction of the hypochloremic, hypokalemic metabolic alcalosis in children with infantile hypertrophic pyloric stenosis (IHPS) is essential to optimal outcome.

Aim:
The main aim of the study was the assessment of the implementation of hospital guidelines for intravenous fluid therapy in children with IHPS.

Material and methods:
In our Department, at the beginning of 2018 hospital guidelines for intravenous fluid therapy in children were implemented. Two internal audits were performed and surgeons’ compliance with the current recommendations was evaluated. We assessed: the type of fluid transfused, a rate of transfusion and whether saline bolus was given. The study group consisted of 50 patients.

Results and discussion:
After new guidelines were implemented, appropriate iv fluid was given to 68.7% of children compared to 5.1% before implementation (P = 0.0001). Proper transfusion rate was used in 44.1% of patients before introduction of new guidelines and in 81.2% after that (P = 0.01). Second audit showed that all children had received the recommended iv fluid (P = 0.007) at a good transfusion rate (P = 0.02). In patients who had received the recommended iv fluid, the length of hospital stay after surgery (P = 0.023) and the total length of stay (P = 0.018) were shorter.

Conclusions:
The new guidelines have raised the level of the whole care for children with pyloric stenosis. The internal audits played an important role in their implementation.
Water Cisterns of Rural Settlements in Southern Anatolia in Late Antiquity and the Byzantine Period
Authors: ERDOĞAN Orçun
Published: November 2021

No extensive work has been published to date concerning the cisterns of southern Anatolia. Nor does the recent research present a comprehensive approach especially to the association of cisterns with buildings and open spaces as well as their stylistic features. From this point of view, this paper aims to fill a part of this lacuna by examining the potential role of cisterns located in the Late Antique-Byzantine countryside of southern Anatolia, namely in the areas of Lycia, Pamphylia, Isauria and Cilicia, on the basis of both archaeological and written evidence as well as the author’s observation in the field. In this study, cisterns are evaluated under three main themes. The first presents such basic characteristics of the cisterns as form, material, capacity, decoration, construction techniques and purposes whilst it also examines the water sources and the ways of feedings of the cisterns. The second theme discusses the essential reasons for locating the cisterns at any point of the unstructured spaces of the settlement core such as streets, paths, alleys, public spaces and, of the land situated in the close vicinity of the inhabited area. The last section analyzes the associations of cisterns with churches along with their annexes, houses, olive oil and wine workshops in terms of function and location.

One of the common diseases found in tilapia is a streptococcal disease caused by the Streptococcus agalactiae bacteria. Treatment of this disease is generally done by using antibiotics.  The use of antibiotics in controlling disease in fish can create resistant bacterial strains with certain doses. The use of vaccines is one of the alternative control methods in fish defence against infections. The purpose of this study was to analyze the efficacy of vaccination on seeds through immersion using attenuated active bacteria to increase immunity at the beginning of the spread of streptococcosis disease. The vaccine used was obtained from attenuated Streptococcus agalactiae bacteria through repeated passage ten times. Vaccination was carried out through oral vaccine. Challenge tests were carried out on days 7, 14, and 21 days after vaccination on tilapia larvae by immersion. The result indicated that vaccination using attenuated bacteria could increase lysozyme activity at each observation time compared to control. The mortality of post-challenged larvae on days 7, 14 and 21 post-vaccination was lower than that of unvaccinated seed. The percentage of RPS values up to the 14th day of observation has increased and tends to decrease on the 21st day.
