Authors: Asadi Meysam , Pourhossein Kazem , Noorollahi Younes , Marzband Mousa , Iglesias Gregorio
Published: May 2023

Currently, worldwide attention to clean energy and sustainable energy has been expedited because of its many environmental benefits. In fact, wind and solar energies play a prime role in decarbonizing the energy market. However, finding the most suitable locations for wind/solar power plants is difficult because of the non-homogeneous distribution of these sources. This paper presents a novel method for selecting the optimal locations for wind and solar farms by mapping the space of the decision criteria to the site score. In addition, the multiple linear regression model was used, with the help of the combination of GIS and AHP methods, to model the siting of wind and solar power plants. The site scoring method used in this study is reliable and globally evaluated; therefore, the scores are accurate and effective. To reveal the ability of the proposed method, two study areas were investigated and researched. The results achieved based on the introduced method showed that, in case study 1, areas with an area of about 9, 4 and 7 km2 are suitable for the construction of wind, solar and wind/solar power plants, respectively. This paper also used fourteen existing wind/solar, wind and solar farms from five continents around the world. The results showed that the suggested model acts the same as the real data. In addition to the interest these results hold for the development of renewable energy in the study area, this novel approach may be applied elsewhere to select optimum sites for wind, solar, and combined wind and solar farms.
A Quantitative Framework for Propagation Paths of Natech Domino Effects in Chemical Industrial Parks: Part I—Failure Analysis
Authors: Yang Yunfeng , Chen Guohua , Zhao Yuanfei
Published: May 2023

Along with global climate change and industrialization, domino effects caused by Natech events occurred frequently in chemical industrial parks over the past decades. Previous research has not yet proposed a reliable method to obtain all possible paths of Natech domino effects, and moreover, a risk assessment and mitigation system has not been established. The present work aims to develop a quantitative framework for propagation paths of Natech domino effects, which can effectively safeguard the sustainable development of chemical industrial parks. The presentation of this work is divided into two parts: Part I (current paper) proposes a path probability calculation method that can simultaneously consider multiple primary accident scenarios and multi-level domino effects triggered by natural disasters. The proposed method transforms the propagation paths of domino effects into the paths of directed graph by constructing the equipment failure state transition matrix and the equipment failure state transition probability matrix. The depth-first traversal algorithm is used to obtain all possible propagation paths and their propagation probabilities, providing data support for the quantitative risk assessment and prevention and control measures presented in the accompanying paper (Part II). The case study shows that the probability of equipment failure caused by multi-level domino effects triggered by Natech accidents is higher than that of conventional accidents. However, the present work only considers the spatial propagation of domino effects, while their spatio-temporal propagation remains as a further direction for this area of inquiry.
Parametric Assessment of Building Heating Demand for Different Levels of Details and User Comfort Levels: A Case Study in London, UK
Authors: Apostolopoulou Athanasia , Zhu Mingyu , Jin Jiayi
Published: May 2023

The Level of Detail (LoD), a parameter used to define the information contained in building models, is an important factor to consider in modeling building energy at the urban scale. In this research, we conducted a parametric study regarding the data requirements for the estimation of the annual residential heat demand in London. More particularly, the requirement of the observation of the actual roof type (LoD2) and the window-to-wall ratio (LoD3) was examined in two different case study areas. Meanwhile, an adaptive comfort level study was implemented using LoD5 models, and its results were assessed holistically with the heat demand to reveal the energy performance of the buildings. The results showed that there was a minor difference in the upgrade of a lower to higher LoD regarding these parameters. At an urban scale, the energy demand of buildings could be estimated using an assumption of archetypes and building ages. However, with a scalable parametric script developed in places, models with a high LoD could provide more detailed insights in the energy performance assessment without generating excessive workload.
New Technique for Monitoring High Nature Value Farmland (HNVF) in Basilicata
Authors: Fiorentino Costanza , D’Antonio Paola , Toscano Francesco , Donvito Angelo , Modugno Felice
Published: May 2023

The definition of High Nature Value Farmland Areas (HNVF) was provided by Andersen in 2003: “HNVF comprises those areas in Europe where agriculture is the major (usually the dominant) land use and where that agriculture supports or is associated with either a high species and habitat diversity, or the presence of species of European conservation concern or both”. The present work focuses on an overview of the techniques used to produce HNVF maps at different spatio-temporal resolutions. The proposed approach is based on the statistical approach. The study area is the Basilicata region (southern Italy) in 2012, mapped at municipal spatial resolution. The HNVF areas were identified by applying a threshold to the sum of the contributions of the main characterizing indicators. Three indicators contribute to the calculation of the HNVF areas: crop variability (CD Index), extensive practices (EP Index), and the presence of natural elements (Index Ne). Good agreement was found between our HNVF map and the results of the literature, although the analysis approaches were different. The main advantages of the proposed methodology derive from only free input data being used, and include remote sensing images and the adaptability to different spatial resolutions (local, regional, and national).
Optimal Strategies of Customization and Information Sharing in the Presence of Feature Creep
Authors: Ma Yong , Li Chunyu
Published: May 2023

Feature creep captures the phenomenon that additional features result in product complexity and even decrease the usability of products. According to consumers’ heterogeneous tastes for products’ sophisticated features, we divide them into the low-end segment and the high-end segment. The proportions of the two segments are uninformed as to the manufacturer, but known to the platform. We take into account feature creep, and consider a supply chain consisting of a manufacturer and a platform. The manufacturer decides whether to adopt customization strategy, and the platform decides whether to share its private information. By formulating several sequential game models, we explore both firms’ optimal strategies and then examine the impacts of customization production and information sharing on environmental performance. Our findings reveal that adopting customization strategy can drive the manufacturer to improve its innovation efforts and raise the wholesale price. Additionally, if the low-end consumers’ proportion exceeds the manufacturer’s expectations, this improvement can be enhanced when the platform shares its private information, and vice versa. Furthermore, if the cost that the manufacturer takes to embed various functions in the product is quite small, it is environmentally friendly for the manufacturer to adopt customization strategy. While, if the cost is relatively large, taking customization strategy causes even greater negative effects on the environment. In addition to generating higher profits for both parties, the platform sharing its private information also contributes to lowering the environmental performance in certain conditions.

Authors: Palcut Marián , Gerhátová Žaneta , Šulhánek Patrik , Gogola Peter
Published: May 2023

Corrosion is the degradation of materials in oxidizing environments. In aqueous solutions, it is initiated by the surface reaction of the metallic material with the surrounding electrolyte. The corrosion rate of metals can be significantly reduced by the presence of organic compounds. Crude glycerol is an organic by-product of biodiesel, soap, and fatty acid production. It is produced in substantial amounts through transesterification. Crude glycerol contains several impurities and has low economic value. Its disposal in the environment is unwanted and potential applications need to be explored. In the present short communication, steel corrosion in crude glycerol has been investigated for the first time. The corrosion behavior of low-alloy structural steel S355MC in non-purified crude glycerol was studied by electrochemical methods. The results were compared with the use of tap water. The open-circuit potential (OCP) of S355MC in crude glycerol was more negative compared with that of tap water. The OCP was stable over time, indicating the rapid passivation of the steel substrate. The corrosion resistance was further studied by electrode polarization. On the polarization curve of S355MC in crude glycerol, a wide passivation region was found. Furthermore, the corrosion rate was 2.2 times smaller compared with that of tap water. The surface exposed to tap water was significantly degraded by red rust. The surface of S355MC after exposure to crude glycerol, on the other hand, was less affected by corrosion and covered with a protective layer. The results demonstrate a significant corrosion-inhibiting activity of crude glycerol that could be utilized in various technologies.
Comparative Laboratory Study of the Geochemical Reactivity of the Marcellus Shale: Rock–Fluid Interaction of Drilled Core Samples vs. Outcrop Specimens
Authors: Carpenter Kristen Courtney , Dje Loic Bethel , Achang Mercy , Radonjic Mileva
Published: May 2023

The Marcellus shale is an unconventional reservoir of significant economic potential with Total Organic Carbon (TOC) ranging from 1 to 20%. Hydraulic fracturing is used to extract the shale’s resources, which requires large amounts of water and can result in mineral-rich flowback waters containing hazardous contaminants. This study focuses on a geochemical analysis of the flowback waters and an evaluation of the potential environmental impacts on water and soil quality. Drilled core samples from different depths were treated with lab-prepared hydraulic fracturing fluids. Rock samples were analyzed using Energy Dispersive Spectroscopy (EDS), while effluents’ chemical compositions were obtained using Inductively Coupled Plasma Optical Emission Spectroscopy (ICP-OES). A comparison of results from drilled core samples treated with additives for hydraulic fracturing to those treated with deionized (DI) water confirms that, as expected, the major elements present in the effluent were Ca, Ba, and Cl in concentrations greater than 100 µg/L. The most concerning elements in the effluent samples include As, Ca, Cd, Pb, Se, S, K, Na, B, Mo, and Mn, with Cd and Cr values averaging 380 and 320 µg/L, respectively, which are above safe limits. Se concentrations and high levels of Ca pose major safety and scaling concerns, respectively. We also compared Marcellus shale drilled core samples’ geochemical reactivity to samples collected from an outcrop.

Published: May 2023

Tidal inlets with attached sand spits are a very common coastal landform. Since the evolution of sand spits along coastlines influence the social-economic development of local coastal areas, sand spits have become the objects of numerous studies. However, previous studies have mainly focused on sand spits that are usually in the scale of hundreds of meters in width, whilst knowledge about the evolution of smaller-scale sand spits still remains limited. Therefore, in this study, the morphological change of a small and unexplored sand spit in front of Song Tranh Inlet on the west coast of Phu Quoc Island, Vietnam is investigated. Satellite images are first used to observe the morphological change of the sand spit and calculate the longshore sediment transport rates (LSTR) along the sand spit. Waves and beach sediments are collected at the study site to calculate the longshore sediment transport rate using the CERC formula. It is found that there is a seasonal variation in the evolution of the sand spit at Song Tranh Inlet. The longshore sediment transport rates along the spit calculated by image analysis are 39,000 m3/year, 66,000 m3/year, and 40,000 m3/year, whilst the longshore sediment transport rate calculated by the CERC formula is 72,000 m3/year. This study aims to contribute to the methodology for investigating the evolutions of small sand spits and, specifically, sustainable coastal management for Phu Quoc Island, which is well-known as the Pearl Island of Vietnam.
Classification of Water Source in Coal Mine Based on PCA-GA-ET
Authors: Yang Zhenwei , Lv Hang , Wang Xinyi , Yan Hengrui , Xu Zhaofeng
Published: May 2023

In recent years, inrush water has hampered the regular mining of coal mines, and the proper identification of the source of inrush water is critical to the prevention and management of water hazards in mines. This paper extracts the standard water chemistry discriminating ions Na++K+, Ca2+, Mg2+, Cl−, SO42−, and HCO3− from observed water samples. An improved water source discrimination model is proposed which combines algorithms from data mining, classification models, and learning reinforcement. According to the Pearson correlation coefficient, Na++K+ has a strong correlation with HCO3−. To identify the major metrics, we performed principal component analysis (PCA), and the adaptive differential evolutionary genetic algorithm (GA) was utilized to optimize the depth of the extreme tree (ET) and the number of classifiers. Finally, the model distinguished 25 sets of studied samples from various water sources in the Pingdingshan coalfield. Comparative analysis demonstrated the efficacy of each stage of our work. PCA-GA-ET outperformed the conventional approaches, such as the support vector machine, BP artificial neural network, and random forest. The studies revealed that PCA-GA-ET can eliminate the information overlap between data and simplify the data structure and thereby improve the efficiency and accuracy of water source detection. We discovered that by utilizing the evolutionary algorithm to optimize parameters such as the depth of the extreme trees and the number of decision trees, we could get the model to converge faster and to be more stable and more accurate. The results suggest that PCA-GA-ET has good robustness and accuracy and can meet the needs of water source identification.
Characterisation of the Hydrogeological Properties of the Ntane Sandstone Aquifer Using Co-Seismic and Post-Seismic Groundwater Level Responses to the Mw 6.5 Moiyabana Earthquake, Central Botswana
Authors: Marema Tshepang Mmamorena , Molwalefhe Loago , Shemang Elisha M.
Published: May 2023

The 3 April 2017 Mw 6.5 Moiyabana earthquake (Central Botswana) had a significant impact on groundwater levels; a gradual co-seismic increase and a stepwise decline in groundwater levels were observed in response to the earthquake at boreholes MH2 and Z12836, respectively. In this study, we investigated the response of groundwater levels to Earth tides by computing the amplitude and phase shift of the M2 tidal constituent to estimate the temporal variations of the storativity, transmissivity, and permeability of the Ntane sandstone aquifer (the main aquifer system) prior to and after the earthquake event. The storativity and permeability computed for borehole MH2 showed a decrease in magnitude of 3.17432 × 10−4 and 1.85 × 10−13 m2 respectively, indicating that strong ground shaking at borehole MH2 might have consolidated the aquifer material, thus resulting in decreased aquifer permeability. The aquifer coefficient of storativity decreased by 2.85 × 10−4 while permeability was enhanced by 0.047 × 10−13 m2 at borehole Z12836. Enhanced permeability might have resulted from increased/enhanced fracturing of the aquifer, fracture clearing and dynamic shaking.

Field observations, together with the results of gas chromatography–mass spectrometry (GC-MS) and stable carbon isotope analysis of bitumen, coupled with fluid inclusion microthermometry and stable isotope analyses of closely associated vug- and fracture-filling columnar calcite in the Upper Cretaceous Bekhme Formation, Kurdistan Region of Iraq, suggest that the degradation of crude oil was caused by the regional incursion of meteoric waters. This incursion, which is interpreted to have occurred during tectonic uplift during the Zagros Orogeny, is evidenced by: (i) the depletion of n-alkanes and acyclic isoprenoid alkanes (pristane and phytane) in the bitumen; (ii) low δ13CVPDB values (−8.5‰ to −3.9‰) and δ18OVPDB values (−22.9‰ to −15.0‰), with more radiogenic Sr isotopic ratios (0.70771–0.70772) compared to Cretaceous seawater; and (iii) low salinity and low temperatures (20 to 40 °C) in fluid inclusions of the columnar calcite. This study demonstrates that regional meteoric water incursion into sedimentary basins can be linked to crude oil degradation accompanied by calcite cementation events in carbonate reservoirs.

Published: May 2023

The accurate simulation of the dynamics of the anaerobic–anoxic–oxic (A2O) process in the biochemical reactions in wastewater treatment plants (WWTPs) is important for system prediction and optimization. Previous studies have used real-time monitoring data of WWTPs to develop data-driven predictive models, but these models cannot be used to provide mathematical analysis of A2O dynamic properties. In this study, we developed a new simulation and analysis method for determining A2O dynamics in biochemical reactions using deep learning and the Koopman operator to address the above problems. This method was validated through data from a real-world WWTP in east China and compared it with the traditional deep learning model. According to the results, the new method achieved high-accuracy prediction. Meanwhile, with the help of the Koopman operator, the new method was able to analyze the asymptotical stability and convergence behavior of the A2O process, which provides a brand-new perspective for the in-depth study of biochemical reactor dynamics.
Construction of Nitrogen Content Observer for Fuel Cell Hydrogen Circuit Based on Anode Recirculation Mode
Authors: Li Weisong , Wei Xuezhe , Wang Jiayuan , Wang Xueyuan
Published: May 2023

The anode recirculation mode is increasingly being adopted in today’s fuel cell systems. The recycling of hydrogen gas can effectively improve fuel utilization and the wider economy. However, using the purge strategy for the recirculation exhaust has a significant impact on the operational performance and economic efficiency of fuel cell systems.Experiments have shown that, when the purge interval increases from 6 s to 10 s, the recirculation pump power increases by about 20%, the nitrogen content in the exhaust gas increases, and the stack voltage shows a 10 V attenuation. The accumulation of nitrogen permeation in the anode circuit leads to the degradation of the fuel cell performance. Therefore, it is necessary to discharge the accumulated nitrogen through the purge valve in a timely manner. However, opening the exhaust valve with excessively high frequency can result in the unreacted hydrogen being discharged, which reduces the economic efficiency of the fuel cell. This paper is based on the principle of mass conservation and models each subsystem of the anode circuit in the recirculation pump mode of the fuel cell separately, including the proportional valve model, the hydrogen consumption model of the fuel cell, the nitrogen permeation model of the fuel cell, the neural network model of the circulating pump, and the purge valve model. These submodels are integrated to construct a nitrogen content observer for the hydrogen circuit, which can estimate the nitrogen content. The accuracy of the model is validated through experimental data. The estimation error is less than 5.5%. The nitrogen content in the anode circuit can be effectively estimated, providing a model reference for purge operations and improving hydrogen utilization.

Treatment burden for people experiencing homelessness with a recent non-fatal overdose: a questionnaire study
Authors: Jones Caitlin , Mair Frances S , Williamson Andrea E , McPherson Andrew , Eton David T , Lowrie Richard
Published: May 2023

Background

People experiencing homelessness (PEH) who have problem drug use have complex medical and social needs, with barriers to accessing services and treatments. Their treatment burden (workload of self-management and impact on wellbeing) remains unexplored.

Aim

To investigate treatment burden in PEH with a recent non-fatal overdose using a validated questionnaire, the Patient Experience with Treatment and Self-management (PETS).

Design and setting

The PETS questionnaire was collected as part of a pilot randomised control trial (RCT) undertaken in Glasgow, Scotland; the main outcome is whether this pilot RCT should progress to a definitive RCT.

Method

An adapted 52-item, 12-domain PETS questionnaire was used to measure treatment burden. Greater treatment burden was indicated by higher PETS scores.

Results

Of 128 participants, 123 completed PETS; mean age was 42.1 (standard deviation [SD] 8.4) years, 71.5% were male, and 99.2% were of White ethnicity. Most (91.2%) had >5 chronic conditions, with an average of 8.5 conditions. Mean PETS scores were highest in domains focusing on the impact of self-management on wellbeing: physical and mental exhaustion (mean 79.5, SD 3.3) and role and social activity limitations (mean 64.0, SD 3.5) Scores were higher than those observed in studies of patients who are not homeless.

Conclusion

In a socially marginalised patient group at high risk of drug overdose, the PETS showed a very high level of treatment burden and highlights the profound impact of self-management work on wellbeing and daily activities. Treatment burden is an important person-centred outcome to help compare the effectiveness of interventions in PEH and merits inclusion in future trials as an outcome measure.

L’apothéose de Romulus (Ovide, Métamorphoses : livre XIV).
Authors: Salamon Gérard
Published: May 2023

Metamorphoses XIV ends with the apotheosis of Romulus and Hersilie. We can find Romulus’ apotheosis in several literary sources, including historians like Livius and Dionysius of Halicarnassius, whereas the apotheosis of Hersilie, which follows immediately that of Romulus, is mentioned only by Ovid and seems to be an Ovidian invention. Comparison between the two narratives shows some noteworthy differences. The main point is that Romulus’ apotheosis is achieved, without enumeration of his exploits, through the intervention of his father Mars. In the same way, Aeneas, Caesar and finally Augustus win immortality because they have divine parents. Unlike the others, Hersilie, whose apotheosis is very central in the narrative of Roman apotheosis (after Aeneas and Romulus, before Caesar and Augustus), is deified because of her own qualities in accordance with Roman tradition. Among several plausible interpretations, that is to my mind the basic point : the catasterism of Hersilie, at variance with the imperial, ie augustean, way of deification, prefigures Ovid’s own apotheosis due only to his poetical talent which is announced at the end of book XV.
Trois témoins privilégiés de l’état de la culture dans l’Italie de Théodoric : Ennode, Boèce et Cassiodore
Authors: Urlacher-Becht Céline
Published: May 2023

Boethius is the most important intellectual figure of Theodoric’s kingdom. At the instigation of his father-in-law Symmachus, he undertook to enrich the Latin culture via a vast program of scientific and philosophic translations of Greek writings. As shown by Ennodius and Cassiodorus, his contemporaries didn’t understand the interest of these theoretical works : in fact, their culture was basically literary. It may be for that reason that Boethius tried in another way, in his latest writing composed just before his death, to hold the attention of the Roman men of letters by using in a propaedeutic way the rhetoric’s and the poetry’s honey to prepare them at the philosophic reflections developed in the Consolation of Philosophy from 3 p. 10.
L’Épicharme et le prologue des Annales d’Ennius, ou les débuts de la révélation pythagoricienne dans la littérature latine
Authors: Lévi Nicolas
Published: May 2023

This article shows how in two texts of Ennius, the opuscule entitled Epicharmus and the prologue of the Annals, the experience of a revelatory dream is the setting of a disquisition of some aspects of Pythagorean philosophy (the elements doctrine, metempsychosis). In doing so, this article aims at making known fragmentary texts hardly studied in France, that nonetheless happen to be significant in the history of ideas, in particular on account of the posterity in Latin literature of this alliance between the apocalyptic paradigm and Pythagorean philosophy.
Dédier comme une mère. Autour des stratégies maternelles dans l’épigraphie à partir des inscriptions des provinces nord-occidentales
Authors: Béraud Marianne
Published: May 2023

By studying epigraphic material in Roman Northern West, it is to be noticed specificities in mother’s speech. This paper attempts to establish the strategy followed by the mothers to commemorate the memory of their children. This work consists in a study of lexicon and formulas of the inscribed material in order to bring to light the criteria which govern the epitaphs written by mothers. Through the prism of epitaphs, the purpose is to distinguish between epigraphic practices of the father and the mother. Besides, these tombstones developed a motherly identity based on the fact that women claimed the status of mother. They preferred to call themselves «mater » rather than «coniux » . Gender is a key factor to understand the role of the mothers in the roman family. Depending on whether the dedicant is the father or the mother, the epitaphs are imbued with a sexed speech which delivers information on male or female dimension of the dedication.
Quelques remarques sur les Epitaphia d’Ausone
Authors: Wolff Étienne
Published: May 2023

The Epitaphia Heroum bello Troico interfuerunt are associated by Ausonius to the Parentalia (collection of thirty poems dedicated to deceased parents) and the Commemoratio professorum Burdigalensium (commemoration of deceased professors who taught at Bordeaux and / or are originated from Bordeaux), constituting a trilogy on the theme of memory. However the Epitaphia differ significantly from the other two booklets insofar Ausonius has no relationship with those whom he speaks. We study here three main aspects of the work : the treatment of the literary genre of the epitaph ; the report to the Greek source ; the composition and disposition of the poems. The result is a work with the Ausonius personal brand and in which he holds an own speech.

Our aim is to nuance the analysis of Fl. Dupont about Medea atrox which makes her one of the most illustrious monsters in the theatre of Seneca. Yet Horatius had defined Medea as ferox. We emit the hypothesis that the character of Medea owed its complexity to the relation that Seneca the philosopher builds between ira and furor to represent this character.
Le vocabulaire du bonheur et de la joie chez Plaute et Cicéron
Authors: Thomas Jean-François
Published: May 2023

The vocabulary of happiness and joy in Plautus and Cicero.

The terms of these two lexical fields are compared, going deeper than simply the usual translations. Happiness is related to life’s opportunities and changes (fortunatus), is a dynamic of success (felix), or results from a process in which expectations are met,

procuring inner fulfilment (beatus). While gaudium is often more neutral, laetitia refers rather to a strong inner or outer impact. Finally, the links between happiness and joy are complex. The inner fulfilment of happiness restored is scarcely mentioned by Plautus, but characterises the happiness of the philosopher, although Cicero emphasises that the condition of beatus cannot be founded on the exuberance and fragility of laetitia.
L’imitatio au livre X de l’Institution oratoire
Authors: Salamon Gérard
Published: May 2023

In Book X of the Institutio Oratoria, Quintilian devotes chapter 2 to redefining the notion of imitatio and in particular its technical meaning in the rhetorical vocabulary. As a method of forging style through imitation of models, imitatio is at the heart of Quintilian’s curriculum. But more than other authors, he sees all the risks : imitation must not impair the capacity for invention which alone makes it possible to progress. For him, progress is possible even in the oratory, provided that the future orator imitates not the thing produced but the creative gesture made by the predecessors. Practically, therefore, the speaker in formation has to forge his own style imitating, according to the nature of the trials and their different parts, the best in each of his models. This requires an important preparatory work of reading and analyzing models indispensable to make imitation something other than counterfeiting.
Cur igitur scribam miraris (Pont. I, 5, 29) : fonctions de l’écriture épistolaire dans les deux premiers livres des Pontiques
Authors: Roussel Déborah
Published: May 2023

The aim of this paper is to answer Cotta Maximus’ question Cur igitur scribam miraris ? which the poet himself does not directly answer : Miror et ipse / et tecum quaero saepe quid inde petam (Pont. I, 5, 29-30). The traditional purposes of the epistolary communication and more generally of the oratorical speech (probare, delectare, flectere) can’t be enough to justify the writing of Ovid’s Epistulae Ex Ponto. Ovid, by writing versified epistles in exile, seems to reveal a new purpose : sibi superstes uiuere.
Increasing the Clearance of Protein-Bound Solutes by Recirculating Dialysate through Activated Carbon
Authors: Meyer Timothy W. , Lee Seolhyun , Whitmer Luke C. , Blanco Ignacio J. , Suba Josef K. , Sirich Tammy L.
Published: May 2023

Key Points

Conventional hemodialysis provides limited clearance of uremic solutes that bind to plasma proteins.

No studies have yet tested whether increasing the clearance of bound solutes provides clinical benefit.

Practical means to increase the dialytic clearance of bound solutes are required to perform such studies.

Background

Conventional hemodialysis provides limited clearance of uremic solutes that bind to plasma proteins. However, no studies have tested whether increasing the clearance of bound solutes provides clinical benefit. Practical means to increase the dialytic clearance of bound solutes are required to perform such studies.

Methods

Artificial plasma was dialyzed using two dialysis systems in series. In the first recirculating system, a fixed small volume of dialysate flowed rapidly through an activated carbon block before passing through two large dialyzers. In a second conventional system, a lower flow of fresh dialysate was passed through a single dialyzer. Chemical measurements tested the ability of the recirculating system to increase the clearance of selected solutes. Mathematical modeling predicted the dependence of solute clearances on the extent to which solutes were taken up by the carbon block and were bound to plasma proteins.

Results

By itself, the conventional system provided clearances of the tightly bound solutes p-cresol sulfate and indoxyl sulfate of only 18±10 and 19±11 ml/min, respectively (mean±SD). Because these solutes were effectively adsorbed by the carbon block, the recirculating system by itself provided p-cresol sulfate and indoxyl sulfate clearances of 45±11 and 53±16 ml/min. It further raised their clearances to 54±12 and 61±17 ml/min when operating in series with the conventional system (P < 0.002 versus conventional clearance both solutes). Modeling predicted that the recirculating system would increase the clearances of bound solute even if their uptake by the carbon block was incomplete.

Conclusions

When added to a conventional dialysis system, a recirculating system using a carbon block sorbent, a single pump, and standard dialyzers can greatly increase the clearance of protein-bound uremic solutes.

Published: May 2023

Flapping wing air vehicles are unmanned miniature aircraft’s that draw inspiration from birds, bats and insects. They utilize continuous flapping wing motion to generate aerodynamic forces and moments. The fluid structure interaction analysis of biological and artificial flapping flyers is extremely complicated thus an efficient unsteady aerodynamic model is required in such time consuming problems as optimal flapping wing simulation. This project deals with designing a flapping wing air vehicle which includes applying inertial impulsive force to UAV in such a way that the flapping wing air vehicle reaches almost constant flight speed after removing the initial impulsive forces. The flow dynamics are different of the flapping wing air vehicles with that of the fixed wing UAV and this project deals with the utilization of the flapping wing in the UAV to overcome the challenges faced by a fixed wing UAV like maneuverability in remote areas, sound produced and identification during mission. Structural and aerodynamic characteristics of a bird in flight offer benefits over typical propeller or rotor driven unmanned air vehicle (UAV). Hence this study deals with the designing of an flapping wing UAV to overcome these drawbacks of fixed wing UAV.

Geometry has an important place in mathematics education because it forms the basis of mathematical thinking and allows us to see the emergence of logical theory. As in all fields, academic journals, which are among the official communication languages of science, play an important role in the construction, dissemination and use of scientific knowledge in the field of geometry teaching. With reference to this fact, the aim of the study was to examine articles published in the field of geometry teaching and indexed in SSCI (1975-2020) and ESCI (2015-2020) in the Web of Science Core Collection database by bibliometric analysis method. 109 articles related to geometry teaching (72 within the scope of SSCI and 37 within the scope of ESCI) were reached for the given periods. According to the findings of the research, while there has been a recent interest in geometry education within the scope of SSCI and ESCI, the number of articles still published is limited. Therefore, in mathematics teaching, geometry teaching lags behind areas such as arithmetic and algebra. Especially in recent years, it is noted that the keyword “Van Hiele Levels” and the keywords of innovations that technology brings to geometry education such as “Dynamic Geometry”, “Virtual Reality”, “Geogebra” and “Geometry Thinking” are frequently used in articles in the field of geometry teaching. It is observed that, while quantitative research methods are widely preferred in studies within the scope of SSCI in the field of geometry teaching, qualitative research methods are preferred within the scope of ESCI.
The The Social Principle of Inclusive Education and Addressing Diversity in Indian Schools: An Appraisal of Post-Salamanca Initiatives in India
Authors: B K Athira , Rajendran Poornima
Published: May 2023

There are steps formally initiated by the Government of India to maintain its adherence to the norms of Inclusive Education. Such schemes, acts and policy drafts are brought into discussion in this paper along with an appraisal of their draft and scope. This include the Sarva Shiksha Abhiyan which became operational from the year 2001, The Right to Education Act, which is implemented from the year 2009 and the Action Plan for Inclusion in Education of Children and Youth with Disabilities of 2005, which was revised in the year 2009. The discussion is anchored around, though not limited to the aspect of ‘Diversity’ which is very pertinent to the Indian scenario and the philosophy of Inclusion. Cultural and geographical diversity of the Indian sub-continent provoke challenges in ‘Doing Diversity’ in classrooms and at the same time it is contributing for the teacher and the taught. Considering the scope of the concept of social inclusion and inclusive education, the paper argues that at an implementation level, inclusive education should be one that is responsive to diversities in a classroom and cultural space. Rather than reproducing social structures pertaining to the above mentioned social categories of class, gender, language etc., policy drafting and implementation of inclusive education should make certain attempts which are pro-inclusive. They need to be less privileging towards certain ways of learning and certain ways of evaluation, considering the physical and cultural diversities of the learners. In our discussion on these schemes and their scope in ensuring diversity in classrooms, questions pertaining to certain disadvantaged sections are covered including Scheduled Castes, Scheduled Tribes, Gender non-binaries, migrants etc.

The relationship between language and culture has become an integral part of language education in recent times. This study explores the impact of second language learning on the culture of ESL undergraduates at Aligarh Muslim University, AMU, India. The study investigates the status of second language learning effects on undergraduates’ culture in the ESL context; of AMU, India. The study employed a quantitative method to collect the data. A 5-point Likert scale in paper and pencil questionnaire-based study was designed to explore the issue mentioned above based on a dataset of convenience sampling of 286 undergraduate students at AMU, India. The study used structural equation modelling (SEM) through SPSS 20 and Amos 20 for data analysis. The study found an overall significant effect of the selected constructs (attitudes, perception of content, perception of learning)of second language learning on the ESL undergraduates’ culture. According to the research findings, a connection exists between language and culture.
Postcolonial Philosophy in Chimamanda Ngozi Adiche’s Purple Hibiscus
Authors: Santhosh Yedidiah N , Antony Adappatu Ancy
Published: May 2023

Post-colonialism is a useful tool for educating the West about the need of not undermining any culture because of racial differences. The post-colonial discourse criteria of appropriation, abrogation, untranslated terms, hybridity, and affiliation served as the foundation for this study’s text criticism. Since this is the fundamental theme of Chimamanda Ngozi Adichie’s writings in Purple Hibiscus, it implies that African people’s heritage and identity are valued by everyone, particularly those who are quasi, and that the colonial process can be truly ended on the African continent. There must be a different culture to replace the lost indigenous culture.

Published: May 2023

The research literature designates English language proficiency to contemplate as the hierarchy of individual development to Bangladeshi graduates, while insufficient English language proficiency contains several disadvantages in carrier development. Although the contradictions exist in the literature, ELP may oscillate among various groups of graduates grounded on the socioeconomic contextual of Bangladesh. In these circumstances, the study focuses on the hindrances of ELP among the diverse social groups of graduates and how they cope with interferences in career building. The study was conducted in a sequential explanatory design method where the survey and interviews were directed to collect data. The data were collected in random sampling technique for survey while interviews were in stratified random sampling technique. Then the study crossed descriptive analysis in quantitative and thematic analyses in qualitative for triangulation purposes. The study indicates discrimination as ELP’s hindrances strongly varies based on their education level. In contrast, dissatisfaction varies according to income level, and economic imbalance varies among the living status of Bangladeshi graduates. However, the study suggests to increase awareness of language use in career building among the graduates and concern authorities. Moreover, the study recommends to conduct more research on the language use in career building in different dimensions.
