Determination of the Extraction, Physicochemical Characterization, and Digestibility of Sulfated Polysaccharides in Seaweed—Porphyra haitanensis
Authors: Dong Mingshuang , Jiang Yanhui , Wang Chun , Yang Qian , Jiang Xiaolu , Zhu Changliang
Published: October 2020

The aim of the study was to extract Porphyra haitanensis polysaccharides (PHPs) using the water extraction and alcohol precipitation methods and explore their antioxidant activity and physicochemical properties. The single-factor and Box-Behnken response surface methodologies were used to optimize the extraction of polysaccharides from Porphyra haitanensis. Our results showed that the polysaccharide yield was as high as 20.48% with a raw material to water ratio of 0.04, and extraction time of 3 h at 80 °C. The extraction rate observed was similar to the actual extraction rate, thus proving the reliability of the optimization model. The extracted polysaccharides primarily consisted of galactose, glucose, and fucose in the molar ratio 76.2:2.1:1, respectively. The high performance gel permeation chromatography (HPGPC) results showed that the molecular weight of the PHPs obtained was 6.3 × 105 Da, and the sulfate content was 2.7 mg/mL. Fourier infrared spectroscopy was used to analyze the functional groups and structures of the polysaccharides. The effect of concentration, temperature, and pH on the apparent viscosity of the PHPs solution were studied using rheology experiments, which revealed that PHPs were a “non-Newtonian fluid” with shear-thinning behavior. The viscosity of the PHPs gradually increased with increasing sugar concentration, and decreased with increasing temperature, acidity, and alkalinity. Detection of the antioxidant activity of OH*, DPPH*, and ABTS* revealed that the scavenging activity of ABTS* was higher than that of OH* and DPPH* in the concentration range of 1–5 mg/mL. In the experiments of simulating gastric juice and alpha amylase in vitro, it was found that PHPs can better resist digestion of alpha amylase, and have better resistance than fructooligosaccharide (FOS), so PHPs have potential prebiotic activity. These findings demonstrate the potential of PHPs for use in the food and cosmetic industries.
EGOVERNMENT DIGITAL ADOPTION: CAN CHANNEL CHOICE OF INDIVIDUALS BE PREDICTED?
Authors: Papavasiliou Samantha , Reaiche Carmen
Published: October 2020

The shift of public sector services to digital platforms has had ongoing impacts on individuals interactions with government entities and services. This research explores the effectiveness of encouraging users to adopt an eGovernment channel choice to lodge their annual income tax return in Australia. Through the application of a quasi-randomised control trial, two different user groups were tested in order to compare and contrasts the variable of an early message intervention and the potential impact on the lodgers shift to digital channels (i.e. eGovernment support encouraging historically non-digital lodgers group vs null support). This small study suggests that individuals are encouraged to use digital services when Government provides support, and that they are more likely to displays predictive behaviours of adoption to these digital channels. Furthermore, there are two main characteristics which predict the users choosing to shift (i.e. age and deductive benefits). Through the use of strategically placed encouragement and digital assistance, it makes an individual more likely to shift to digital channels. However, this research demonstrates predictive analytics has a stronger place in the long term adoption of eGovernment services.
Control Factors on the Heat Treatment Process Applied to A537 Steel for Increasing Hardness Using Hardening and Tempering
Authors:   ", CAZACU Nelu ,   Dunarea de Jos",   University of Galati, Romania
Published: October 2020

The paper is based on laboratory experiments of heat treatments applied to samples of A537/A537M steel. The work continues other previous works aimed at modifying structures and properties of this steel, including through surface treatments. The experiments were performed using Taguchi methods from Quality Engineering. A number of four factors were selected as influencing the structure after heat treatment: heating temperature for hardening, cooling rate on hardening, time and tempering temperature. A number of nine experiments were performed using an L9 orthogonal matrix. Objective function was changed to maximum hardness after the heat treatment regime. The results show that the tempering temperature has the greatest influence on the final hardness of the A537 steel samples.

The paper deals with the behaviour at hydrodynamic action of the geotextiles used in carrying out the regularization and shore defence works located in riverbed. The geotextiles have lately presented applications for the execution of bottom thresholds, of the management dams in riverbed. Also, geotextiles have become an important component in the structure of river defence works on riverbeds. The research was carried out on the lower course of the Moldova River in the area of Pildesti, Neamţ County. The dynamic action of the floods, through the liquid and solid flows, influences the stability and the resistance over time of the constructions made from geotextiles. The researchers analysed the behaviour of the geo-bags made of polyester bags filled with local materials (sand and gravel stabilized with cement), used in the structure of the bottom thresholds, steering dams and in the shore defence works. The research results indicate a differentiated behaviour of the geo-bags depending on the location (in the water, or on the shore) and the mode of action of the water (dynamic or static). The action of the water, through the liquid and solid flow, degraded the structure of the geo-bags by breaking and emptying the filling material. The geo-bags showed a reduced resistance to the action of the alluvial material, especially when the dosage of cement indicated by the design was not achieved. The research highlighted the good behaviour of the geo-bags in the erosion phenomenon of the riverbed, when they were mulched on the erosion zones and ensured the continuity of the constructions in the riverbed (bottom thresholds and shore defences).
Análisis del nuevo texto del artículo 533º del Código Procesal Civil y la tercería de propiedad contra hipotecas
Authors: Lama More Héctor Enrique
Published: October 2020

Históricamente, la tercería excluyente de propiedad ha sido un medio de defensa de un tercero cuyos bienes han sido objeto de medidas de embargo o de secuestro dictadas por un juez en un proceso en el que dicha persona no es parte. Ello se encuentra en estricta coincidencia con una correcta interpretación del texto anterior del artículo 533º del C. P. C; sin embargo, la Sala Civil Permanente de la Corte Suprema de Justicia, durante los años que van del 2006 a 2007 y parte del 2008, sostuvo que cuando la referida norma señalaba que la tercería puede fundarse en la propiedad de bienes afectados con medida cautelar o para su ejecución, se debía incluir también en dicho supuesto «la ejecución de garantías reales». Esto motivó la modificación —introducida por Decreto Legislativo Nº 1069— del texto del primer párrafo del artículo 533º del C. P. C., y se introdujo en dicha norma procesal la palabra «judicialmente» a efecto de quitar cualquier duda sobre la naturaleza de la afectación jurídica que recae sobre los bienes que según el tercerista serían de su propiedad
Exégesis de la Constitución económica
Authors: Chanamé Orbe Raúl
Published: October 2020

La Constitución económica es una creación del siglo XX y tenemos a la Constitución de Weimar como pionera y base de este pensamiento, radicando su principal aporte en un reconocimiento expreso al contenido de la economía dentro de una Constitución. En el caso particular de las Constituciones del Perú, si bien casi siempre existieron referencias económicas y financieras en ellas, esto no siempre puede ser entendido en términos de una Constitución económica como concepto orgánico. Si bien un punto de quiebre importante del paradigma constitucional se da con la Constitución promulgada en 1920, la primera del siglo XX, que señala el inicio del constitucionalismo social en el Perú e impacta indirectamente sobre la economía y el capital; es fundamentalmente en los últimos 30 años que en el Perú se fueron procesando y actualizando los principios que rigen el régimen económico de su Constitución: economía social de mercado, libertad de contratar, libre competencia, pluralismo económico, igualdad de tratamiento capital y derecho del consumidor, entre otros.
La identidad: su estudio integral

Published: October 2020

La identidad es un derecho que se ejerce frente a la humanidad entera, y a pesar de esa trascendencia, en el campo de la organización social, se ha estudiado mucho las clases sociales, pero a partir de una visión occidental y desde el punto de vista del ingreso per cápita, es decir, señalando características socioeconómicas y dejando de lado la valoración de los elementos culturales de los grupos ancestrales y pueblos indígenas. Esto ha dado lugar a que hoy se hable de grupos excluidos del ejercicio de sus derechos y de la existencia de ciudadanos de segunda clase.

Formación de magistrados en Brasil
Authors: Borges de Freitas Graça Maria
Published: October 2020

Los sistemas de selección y formación de magistrados poseen peculiaridades vinculadas a la tradición jurídica adoptada por cada país; sin embargo, más que relación con el sistema jurídico adoptado por el país, estos criterios de selección y formación hacen referencia al sitio y al rol que tiene el Poder Judicial en la organización del Estado, y en tal sentido, lo que de ninguna manera podrá quedar de lado es que la valoración del rol constitucional del juez y el fortalecimiento de los principios del Estado democrático de derecho deben atravesar toda la formación del magistrado, en orden a que los principios fundadores del orden jurídico nacional sean reafirmados por el juez cada vez que aplique el derecho a un caso concreto.

The active distribution network (ADN) is an integral component of the smart grid. The ADN improves reliability and resiliency in the power grid integrated with many distributed energy resources (DERs). This is possible that, during outage, the ADN can be isolated from the main grid and it can continue to operate in island mode with indeterminate broken links and scarce generation resources. With the active management of increasing DERs, the distribution network is changed to active distribution network from passive network. This paper reviews the characteristics and challenges of deployment of distributed power plants (DPPs) in hierarchical active distribution network
Redefining Engineering Education in Africa through Delivering Total Engineering
Authors:   Mangosuthu University of Technology, Durban, South Africa., Fomunyam Kehdinga George
Published: October 2020

Engineering education in sub-Saharan Africa has the potential to contribute to economic and social development of any country. But it has not been leveraged on appropriately to culminate in economic and social development in the countries in Africa. This implies that for Africa as a region to leverage fully on the potentials of engineering education to ensure economic and social development, it must be redefined through delivering total engineering. This study was a theoretical discourse on redefining engineering education in Africa through delivering total engineering and evidences from established literature were used in giving more credence to the work. Delivering Total engineering is a composite of three words which are delivering, total and engineering. This study conceptualized what delivering total engineering and it was defined as an educational perspective which showcases the relationship between learning and teaching which is crucial to innovation in the delivery of capable, competent and confident graduate which are the outcomes. Findings revealed that the three dimensions (delivering, total, engineering) are crucial in redefining engineering education in Africa and they were analyzed in support of this study. The study therefore recommends intensification of effort on research on delivering total engineering as it has no theoretical basis. Pragmatism is also important to verify the veracity of the concept.

Many factors have led to the increase of suicide-proneness in the present era. As a consequence, many novel methods have been proposed in recent times for prediction of the probability of suicides, using different metrics. The current work reviews a number of models and techniques proposed recently, and offers a novel Bayesian machine learning (ML) model for prediction of suicides, involving classification of the data into separate categories. The proposed model is contrasted against similar computationally-inexpensive techniques such as spline regression. The model is found to generate appreciably accurate results for the dataset considered in this work. The application of Bayesian estimation allows the prediction of causation to a greater degree than the standard spline regression models, which is reflected by the comparatively low root mean square error (RMSE) for all estimates obtained by the proposed model.

Authors: Suresh Parvathy , Kuriakose Sobha , Kurian Joy , Rajan Soumya , Raghuvaran Reshmi
Published: October 2020

Aim: To assess the protective effects of Silver Diamine Fluoride (SDF) against pediatric liquid medicament – induced enamel demineralization of deciduous teeth. Materials and methods: Ninety deciduous incisors were equally divided into three groups of 30 teeth each: without SDF pretreatment (group 1), with SDF pretreatment (group 2) and control group in artificial saliva (group 3). Group 1 and 2 were again divided into 3 subgroups of 10 each, according to the immersion solutions: sodium valproate, salbutamol sulphate and multivitamin. Vickers microhardness was measured at the pre-immersion stage and at regular intervals(7,14,21,28 days). Qualitative analysis was done using Scanning Electron Microscope (SEM) and the values were tabulated for statistical analysis. Results and Discussion: Evaluating the results of hardness tests, all the three medicines investigated could produce evident decrease in Vickers microhardness of all the tested enamel surfaces. Statistically significant erosion occurred (p < 0.05) at all tested days in the multivitamin group, while sodium valproate and salbutamol were able to cause significant change only at the end of the 28 day cycle. The application of 38% SDF on the teeth samples prior to the erosive cycles was able to significantly reduce enamel erosion i.e, the reduction in hardness caused by erosion was statistically lesser in the SDF pretreated group. SEM images after 28 days revealed that all the tested surfaces clearly exhibited structural loss, which was unlike those immersed in artificial saliva. Conclusion: The qualitative and quantitative analysis of enamel samples pretreated with silver diamine fluoride suggested desirable protective effects of SDF on enamel against drug – induced erosive changes.

Legal Ground of Choice of Law Agreement Permissibility in International Commercial Arbitration
Authors:   North Caucasian Branch of Russian State University of Justice (Krasnodar), Novikova T. V.
Published: October 2020

Problem statement. Specific nature of international commercial arbitration raises an issue whether in this case lex fori is capable to be the ground of choice of law agreement permissibility. Topicality of the issue is determined by the Supreme Court of the Russian Federation explanation of 09 July 2019 to courts referring issues of choice of law permissibility to lex fori. Goals and tasks of the research. Goal – research of legal ground of choice of law permissibility in international commercial arbitration. Tasks: to study the ICAC approaches to choice of law acknowledgement; to advance a hypothesis on the influence of explanation by the Supreme Court of the Russian Federation in respect of article 1210 of the Russian Federation Civil Code to the ICAC practice and to draw a conclusion on the international commercial arbitration «procedural documents» provisions as the ground for it to acknowledge choice of law agreement. Methods. Methods of formal logic play a key role: analysis of the ICAC practice permitted to distinguish three approaches to choice of law agreement permissibility grounding; induction of ratio decidendi of the ICAC separate decisions – to draw a conclusion on the article 1210 of the Russian Federation Civil Code influence to the ICAC practice in general and on this basis to advance a hypothesis on possible influence of explanations by the Supreme Court of the Russian Federation in this respect; comparison of the international commercial arbitration rules – to draw a conclusion that these provisions are the ground of choice of law acknowledgement by the tribunal. Results, brief conclusion. Firstly, three approaches of the ICAC to the choice of law agreement permissibility grounding have been revealed and in each them the ICAC relies on the article 1210 of the Russian Federation Civil Code. As far as the article 1210 has an impact on choice of law permissibility grounding within the ICAC, explanations by the Supreme Court of the Russian Federation in respect of this article are capable to have a possible impact on the ICAC practice. Secondly, within the international commercial arbitration the choice of law agreement permissibility grounding should be based on provisions of its «procedural documents», e. g. national law on international commercial arbitration, rules of institutional arbitration or ad hoc arbitral tribunal, – these rules (but not conflict of laws addressed to courts of the state of the arbitration seat) could be considered as its peculiar lex fori.
Hidden Labor Relations: Current Law-Making and Law Enforcement Issues
Authors:   Russian State University of Justice (Moscow), Voronov I. Yu.
Published: October 2020

The article analyzes the positions of experts in the field of labor law regarding the nature and types of hidden labor relations from the positions of positivism and the scientifically based concept of integrative law understanding. The author criticizes the conclusions of experts based on a positivist legal understanding according to which an employment relationship arises on the basis of the reclassification of a civil contract into an employment contract or a civil relationship into an employment relationship. Based on the analysis of labor law norms, law enforcement practice in labor disputes and scientific points of view of experts in the field of labor law, which is based on a scientifically based concept of integrative law understanding, the author comes to the conclusion that hidden labor relations are a type of labor relations, have signs of labor relations, are common in the judicial practice of labor disputes and are the most urgent problem of Russian labor law. The author analyzes two modern types of hidden labor relations from the position of a scientifically based concept of integrative law understanding: the conclusion of civil contracts instead of labor contracts and the actual admission of an employee to work by the employer or with the knowledge or on behalf of the employer or its authorized representative in the case when the labor contract was not properly executed, within three days and later after the actual admission of the employee to work. The author analyzes the ways of protection of labor rights and legal interests in the field of labor from the position of a scientifically grounded concept of integrative law understanding and formulates law-making proposals for changing the norms of labor law.

Ao problematizar a educação matemática para pessoas jovens, adultas e idosas, identificamos que nesse contexto educacional há necessidade de promover propostas pedagógicas de caráter emancipatórias, onde o uso de metodologias ativas qualifica o processo de ensino-aprendizagem. Nesse sentido, entende-se que, o ensino da matemática possibilita formas ativas e participativas de ensinar e aprender, onde os estudantes possam assumir o protagonismo no processo educativo. Ao longo do texto buscamos o diálogo com diferentes autores que tratam da perspectiva educativa aqui desenvolvida. O projeto desenhado, apesar de factível no contexto escolar da EJA, deverá ser implantado e seus resultados analisados em trabalhos posteriores.

Further Evidence for Significant Luminosity Evolution in Supernova Cosmology

Supernova (SN) cosmology is based on the assumption that the corrected luminosity of SNe Ia would not evolve with redshift. Recently, our age dating of stellar populations in early-type host galaxies (ETGs) from high-quality spectra has shown that this key assumption is most likely in error. It has been argued though that the age–Hubble residual (HR) correlation from ETGs is not confirmed from two independent age data sets measured from multiband optical photometry of host galaxies of all morphological types. Here we show, however, that one of the data sets is based on highly uncertain and inappropriate luminosity-weighted ages derived, in many cases, under serious template mismatch. The other data set employs more reliable mass-weighted ages, but the statistical analysis involved is affected by regression dilution bias, severely underestimating both the slope and significance of the age–HR correlation. Remarkably, when we apply regression analysis with a standard posterior sampling method to this data set comprising a large sample (N = 102) of host galaxies, very significant (>99.99%) correlation is obtained between the global population age and HR with the slope (−0.047 ± 0.011 mag Gyr−1) highly consistent with our previous spectroscopic result from ETGs. For the local age of the environment around the site of SNe, a similarly significant (>99.96%) correlation is obtained with a steeper slope (−0.057 ± 0.016 mag Gyr−1). Therefore, the SN luminosity evolution is strongly supported by the age dating based on multiband optical photometry and can be a serious systematic bias in SN cosmology.

Galaxies in dense environments, such as groups and clusters, experience various processes by which galaxies gain and lose gas. Using data from the SDSS-IV MaNGA survey, we previously reported the discovery of a giant (6—8 kpc in diameter) Hα blob, Totoro, about 8 kpc away from a pair of galaxies (Satsuki and Mei) residing in a galaxy group that is experiencing a group–group merger. Here, we combine interferometric 12CO(1–0) molecular gas data, new wide-field Hα, u-band data, and published X-ray data to determine the origin of the blob. Several scenarios are discussed to account for its multiwavelength properties, including (1) Hα gas being stripped from the galaxy Satsuki by ram pressure, (2) a separated low-surface-brightness galaxy, (3) gas being ejected or ionized by an active galactic nucleus (AGN), and (4) a cooling intragroup medium (IGM). Scenarios (1) and (2) are less favored by the present data. Scenario (3) is also less likely as there is no evidence for an active ongoing AGN in the host galaxy. We find that the CO (cold) and Hα (warm) gas coexist with X-ray (hot) structures; moreover, the derived cooling time is within the regime where molecular and Hα gas are expected. The coexistence of gas with different temperatures also agrees with that of cooling gas in other systems. Our multiwavelength results strongly suggest that the CO and Hα gas are the product of cooling from the IGM at its current location, i.e., cooling has occurred, and may be ongoing, well outside the host-galaxy core.
Citoyenneté refusée : les employées domestiques face à la régulation du travail à La Réunion (1945-1960)
Authors: Paris Myriam
Published: October 2020

En 1945, des employées domestiques créent, à La Réunion, le Syndicat des bonnes et des blanchisseuses et prennent part à un large mouvement anticolonial réclamant l’égalité des droits politiques et sociaux entre Français·es et Réunionnais·es. Appuyé sur des sources militantes et administratives, cet article a l’ambition de montrer que l’analyse des mobilisations, de ces employées d’une part et celle des réponses institutionnelles qui y sont apportées entre 1945 et 1960 d’autre part, constituent un angle privilégié pour saisir les modalités du maintien et du renouvellement d’un régime colonial appuyé sur les clivages sociaux de genre, de classe et de race, et ce, au moment même où, dans le cadre de la départementalisation amorcée en 1946, une citoyenneté politique et sociale française se construit localement.
La division sexuée du travail revisitée en Chine rurale aujourd’hui
Authors: Hou Renyou
Published: October 2020

Depuis les années 1980, la contribution grandissante des femmes chinoises aux activités productives de par la valorisation sociale et économique de la main d’œuvre féminin, ainsi que leur participation non négligeable aux activités sociales et communautaires pourraient donner l’impression, a priori , que l’idéologie confucéenne de la séparation des sexes dans la société chinoise, connue sous l’expression de « l’homme se charge des affaires extérieures, la femme des affaires intérieures » ( nanzhuwai , nüzhunei ), tendrait à s’atténuer. À partir d’une étude ethnographique réalisée au village de Zhang (province du Henan) entre 2013 et 2016, cet article démontre que la division sexuée du travail dans les activités productives et sociales reconfigure et redéfinit ce qui est « intérieur » et ce qui est « extérieur » dans un contexte migratoire important, mais dont la valeur d’homme-extérieur/femme-intérieur perdure et continue de réguler l’organisation de la vie des villageois·es.
Optimal strategies for CSIDH

Published: October 2020

Since its proposal in Asiacrypt 2018, the commutative isogeny-based key exchange protocol (CSIDH) has spurred considerable attention to improving its performance and re-evaluating its classical and quantum security guarantees. In this paper we discuss how the optimal strategies employed by the Supersingular Isogeny Diffie-Hellman (SIDH) key agreement protocol can be naturally extended to CSIDH. Furthermore, we report a software library that achieves moderate but noticeable performance speedups when compared against state-of-the-art implementations of CSIDH-512, which is the most popular CSIDH instantiation. We also report an estimated number of field operations for larger instantiations of this protocol, namely, CSIDH-1024 and CSIDH-1792.
Modelling and computation of optimal multiple investment timing in multi-stage capacity expansion infrastructure projects
Authors: Li Jinghuan , Zhang Shuhua , Li Yu
Published: October 2020

So far, the optimal investment timing to maximize the total profit of multi-stage capacity expansion infrastructure projects is not clear. In the case of uncertain demands, the optimal multiple stopping time theory is adopted to model the optimal decision-making of investment timing for multi-stage expansion infrastructure projects in a finite time horizon. In this context, the first-stage of the project involves a dedicated asset investment for later expansion, and the capacity of the project at each stage is constrained, which makes the cash flow of the project exhibit the characteristic of bull call spread. The upwind finite difference method and multi-least squares Monte Carlo simulation are combined to solve the project value and determine the optimal exercise boundaries at all stages described by a sequence of demand thresholds. A multi-stage power plant project is taken as an example to validate the model. Through the example, the optimal investment strategies and the value of the multi-stage project are provided; the effects of the dedicated asset and capacity constraint are illustrated. This study novelly reveals the effect of the capacity constraints on the project value using the bull call spread theory.
