Authors: Ali Nadia Ben Si , Ghoudelbourk Sihem , Zerzouri Nora
Published: October 2022

Today, energy storage systems are strongly present both in industry and for individual applications, especially in on-board systems where an autonomous source of energy is required for power. Energy needs as well as the search for efficient means for its storage have become a very important research axis. Solar battery storage allows to store electricity generated from the sun via solar panels to ensure power supply in all circumstances (day or night, clear or overcast sky). This work focuses on modeling and dynamic simulation of a photovoltaic system with a Lithium Ion battery storage system (LI-BSS). Battery charge and discharge is performed using PWM current and voltage controllers using DC/DC bidirectional management converter BMC.
Maximum Active Power Transmission Efficiency and Apparent Power Definition with Arbitrary Waveforms
Authors: Tacca Hernán Emilio
Published: October 2022

A proof of the theorem giving the maximum available active power with constant transmission losses (i.e., maximum efficiency) valid for arbitrary waveforms, is proposed. This makes it possible to rigorously generalize the definitions of power factor based on the definition of apparent power as the maximum power available to apply them to systems with non-symmetric, non-sinusoidal, and eventually time-varying (i.e., non-periodic) waveforms or DC grids, thus extending its application to hybrid multi-wire systems with asymmetrical phases, with different voltages, frequencies or waveforms (i.e., non-sinusoidal waves, such as rectangular or PWM) and even DC, which can be combined eventually sharing the neutral conductor. Finally, an example of application to a hybrid system composed of DC and unbalanced load inverter-based non-sinusoidal AC subsystems is included.
Deposition-Pellet Preparation Technique for Powder Samples Measurement Using Laser-Induced Breakdown Spectroscopy
Authors: Suyanto Hery , Nasution Aulia M.T. , Trisnawati Ni Luh Putu , Suprihatin Iryanti Eka
Published: October 2022

Laser-Induced Breakdown Spectroscopy (LIBS) is a spectroscopy-based measurement technique that is capable of rapid and accurate qualitative, as well as quantitative, analysis of elemental ingredients either in solid (either for organic or inorganic compounds), liquid, or gaseous samples. Unfortunately, this is not the case for powdered samples, where the focused laser beam will disperse the powder. This can be overcome by making the powder into pellets. But it has an inherent drawback, i.e., the minimum amount of powder is about 0.2 g to obtain a good detectable signal. To cope with this unfavorable condition, especially for the amount of powder less than 0.1 mg, we proposed a sub-target deposition method to make the pellets in this reported work. Using this method, the analyzed powder was deposited into an indented hole on a pellet substrate of KBr with the following optimum conditions, i.e., pellet's pressing pressure of 400 kPa, laser energy of 120 mJ, and a sample's heating temperature of 70℃. Microanalyses of standard powdered samples of PbO, CuO, and ZnO have been carried out with estimated detection limits of 4.7 μg, 4.6 μg, and 3.9 μg, respectively. So, this method can be used to analyze small amounts (in the microgram range) of powdered samples.

Authors: Baskar Sam , Gourbilleau Fabrice , Pratibha Nalini R.
Published: October 2022

Si-C based alloys have attracted much attention due to their potential applications in electronic and optical devices. In this paper, a-SixCy thin films with different Silicon (Si) content are obtained by sputtering of SiC; co-sputtering of SiC and Si targets at different deposition temperatures (Td) such as 200oC, 350oC and 500oC. It is annealed at various annealing temperature (Ta) using conventional thermal annealing (CTA) and Rapid Thermal Annealing (RTA) techniques. The effect of excess Si incorporation and the unintentional oxidation during various stages of sample preparation are discussed. Their structural and optical properties are investigated using spectroscopic ellipsometry, X-Ray Diffraction spectroscopy (XRD), and Fourier Transform Infrared spectroscopy (FTIR). The refractive index value (n1.95eV) varies between 1.6 to 3.6, suggesting the transition from porous silicon carbide to Si-rich silicon carbide or silicon oxycarbide upon increasing Td and Ta, which is also supported by the FTIR spectra. The emergence of absorption peak between ~950 cmâˆ’1 and 1100 cmâˆ’1 with the increase of Ta and excess silicon is attributed to Si-O a stretching vibration bond which is an indication of Si richness and unintentional oxidation during annealing. Detailed analysis on the process parameters and the evolution of phase transformations are discussed.
Interfacial Interaction of Binary Mixtures of Surfactants Hexadecyl Benzylammonium Chloride (HDBAC) and Tween 20 in Aqueous Solutions
Authors: Ali Inaam H. , Kareem Sameer H.
Published: October 2022

The surface adsorption properties of mixed binary surfactants containing hexadecyl benzylammonium chloride (HDBAC) and Tween 20 in aqueous solutions were studied at different temperatures (288-318K) using tensiometry techniques. The interaction parameters and surface activity for both individual and mixed surfactants systems, the Critical Micelle Concentration (CMC), maximum surface excess concentration (Î“max) and minimum surface area per surfactant molecule (Amin) at the air-water interface were determined. Also, the parameters related to synergism in surface activity such as adsorption efficiency (pC20) and CMC/C20 were calculated. The results obtained reveal that the binary mixed system possess CMC values lower than its components and these values decrease with increasing the concentration of Tween 20 in the solution. This behavior shows non-ideal synergism of the mixing process. The values of molecular interaction parameters Î²Ïƒ and the mole fraction of components at the air-water interface X1Ïƒ are calculated on the basis of Rosen's model and showed that the interaction parameter of the adsorbed monolayer is always negative and has a higher negative value for 0.9 Tween mole fractions.
Influence of Some Organic Derivatives on the Corrosion Inhibition of Udimet700 Alloy in 1 M HCl Solution
Authors: Elzanaty Hesham , Mostafa Rania
Published: October 2022

In this study, the electro-chemical behavior of Udimet700 alloys is studied in acidic media at 25°C. It deals with the corrosion inhibition process of nickel–based (Udimet700) alloy in 1M–HCl solution by some organic derivatives. The methods used include electro–chemical frequency modulation technique, electro–chemical impedance spectroscopy, and potentio–dynamic polarization. The derivatives are considered as mixed–type inhibitor depending on potentio–dynamic polarization analysis. Scanning electron microscope examination is executed to study the morphology of Udimet700 surface after immersion in a solution in the case of presence and absence of derivatives. The results of this research reveal that the inhibitors are absorbed by Udimet700 alloy surface and they insulate it from the acidic medium. The compound (C16H17) among the tested organic derivatives plays the best role as an inhibitor of the alloy in 1M–HCl.

Authors: Shikha Deep , Sinha S. K. , Murugesan S.
Published: October 2022

In recent years, synthesis and characterization of Ag-based materials has become an active area of research due to its application in medical area for having antimicrobial properties useful for prosthetic replacement. Pure HydroxyAPatite (HAP) and 1.5wt% Ag-doped HydroxyAPatite (AgHAP) were prepared by sol-gel process and characterized. Ca(NO3)2.4H2O was used as source of Ca precursor, P2O5 was used as a source of P precursor, and AgNO3 has been used as a source of Ag precursor. Pellets of HAP and AgHAP were made after precipitates were consolidated, dried in oven, grounded and sintered in a muffle furnace. Functional groups were determined using FTIR, and compound formations were investigated using XRD. Microstructural analysis was done using SEM and AFM. Wettability was studied using OCA in distilled water, and corrosion resistance and impedance analyses were carried out using ECA in Ringer solution. It was observed from AFM and XRD that grain size decreased from 7.05 ?m to 1.25 ?m. Improvement in corrosion resistance was observed in AgHAP. Wettability studies showed that AgHAP is more hydrophilic in comparison with pure HAP. A correlation between microstructures and properties of hydroxyapetites are discussed in this paper.
Investigation of the effect of Graphene Nanoplatelet content on Flexural Behavior, Surface Roughness and Water Absorption of a Graphene Nanoplatelets Reinforced Epoxy Nanocomposites
Authors: Kesavulu A. , Mohanty Akash
Published: October 2022

In the present work, the effect of Graphene nanoPlatelets (GnP) content on the flexural, surface roughness, and water absorption behavior of a GnP reinforced epoxy composite was investigated. Different wt.% of GnP (0.25, 0.5, 0.75, and 1 wt.%) was added into the epoxy matrix through the sonication method followed by the ball milling. The results indicate a significant enhancement in the flexural properties of the epoxy nanocomposite with the addition of GnP in the epoxy matrix. The optimum enhancement in the properties was obtained at 0.25 wt.% GnP incorporated epoxy composites. The increase in flexural strength and flexural modulus results were noticed as 42.7% and 49.2% when compared with neat epoxy. The surface roughness value for the loading of 0.25 wt.% of GnP into the epoxy showed a drop of 48.7% when compared with that of the neat epoxy sample. The loading of 0.25 wt.% of GnP into the epoxy also reduces the water absorption from 0.125% for the neat epoxy sample to 0.067% for the composite sample. The Scanning Electron Microscope (SEM) images of the fractured surface (flexural samples) of the GnP embedded epoxy composites show the river like pattern, which is the result of the better dispersion of the GnP in the epoxy matrix and thus shows improvement in flexural behaviour of such composite materials.

Bent Core Mesogens are remarkably interesting achiral Liquid Crystals. These grab attention for their utility. The compound, taken for investigation, is a Schiff base addition product, composed of 2-(4β-aminophenyl)-5-(4?β-butyloxyphenyl)-1,3,4- thiadiazole and 4-n-hexadecyloxy salicylaldehyde. The property of this imine derivative is in accordance with liquid crystal and is a Bent Core Mesogen (BCM). The thin layers were prepared with the help of Langmuir-Blodgett apparatus. The morphology and photo-physical characteristics of thin films were examined in comparison to similar BCM derivative of 1,3,4-Oxadiazole. The expectation was the formation of monolayer of molecules on the substrate. Practically there were layer of clusters on the substrate. Both molecules form nano clusters. The typically different aggregates by the thiadiazole moiety in comparison to oxadiazole moiety are revealed. Cluster formation is also supported by the Atomic Force Microscopic (AFM) images.
Acid Modified Graphene Oxide from used Battery Rods Loaded with 2-{(E)-[(3-hydroxyphenyl) imino] methyl} phenol: Electrochemical Detection of Dopamine in Presence of Ascorbic Acid and Uric Acid in Aqueous Medium
Authors: Kumar Das Diganta , Bordoloi Priyakshi
Published: October 2022

The graphite rods of used batteries have been utilized as source for Graphene Oxide (GO). The Acid Modified Graphene Oxide (AMGO) is loaded with Schiff base obtained from salicylaldehyde and 3-amino phenol. Glassy Carbon Electrode (GCE) surface when modified with the Schiff base loaded AMGO acts as electrochemical sensor for Dopamine (DA) in presence of Uric Acid (UA) and Ascorbic Acid (AA). Cyclic Voltammetry (CV), Square Wave Voltammetry (SWV) and Differential Pulse Voltammetry (DPV) shows well separated peaks for DA from UA and AA. The DA peak intensity increases in the three techniques with DA concentration. The linear range for the detection of dopamine is observed from 9.09 × 10-4 M to 1.70 × 10-3 M in presence of 1.00 × 10-1 M Ascorbic Acid and 1.00 × 10-2 M uric acid. The detection limit is estimated to be 9.38 × 10-10 M.
Mozart, Kierkegaard y el patriarcado en La flauta mágica
Authors: CASTRO ERNESTO
Published: October 2022

Por si no os acordáis del argumento de La flauta mágica, os lo resumo. La ópera empieza con un príncipe (Tamino) al que persigue una serpiente. Él se desmaya y, cuando está a punto de ser devorado por ella, irrumpen tres damas que la derrotan. Las tres desean quedarse a solas con el príncipe inconsciente, pero finalmente acuerdan marcharse juntas a informar de lo ocurrido a su superiora, la Reina de la Noche. Tamino se despierta y se encuentra con Papageno, un cazador de pájaros, también al servicio de la Reina, quien se atribuye la derrota de la serpiente. En ese momento, vuelven las tres damas y le cierran el pico al cazador de pájaros («Para que nunca más te jactes / de los actos heroicos / que han hecho otros»). Al príncipe le dan una flauta mágica y le encargan que rescate a la hija de la Reina, Pamina, quien ha sido secuestrada por el sumo sacerdote de la sabiduría (Sarastro). A Tamino le conducen tres muchachos hasta una encrucijada, en la cual se alzan tres templos: el de razón, el de la naturaleza y el de la sabiduría. En este último se encuentra Pamina, a la cual acosa sexualmente el negro Monostatos. Sarastro lo castiga y entonces se revela que él y sus hombres son los buenos. La Reina y sus mujeres son, en verdad, las malas. Ellos han secuestrado a Pamina para una causa tan bondadosa como es iniciarla en la sabiduría por medio del amor. Tamino y Pamina se enamoran; pero es él, no ella, quien hará frente, junto con Papageno, a las pruebas de iniciación. La primera consiste en quedarse callado. Papageno no lo consigue («¡Que yo no pueda dejar de parlotear / es realmente una vergüenza para mí!»); Tamino, sí. Hasta tal punto lo consigue que Pamina decide suicidarse porque su amado no le dirige la palabra. Papageno también va a colgarse de un árbol, pero en el último momento le obsequian su Papagena. En cuanto a Pamina, los tres muchachos la convencen de que no se mate («Una mujer que no teme / ni a la noche ni a la muerte / es digna de ser iniciada») y ayuda a Tamino a superar las dos últimas pruebas, atravesar el agua y el fuego, mientras él toca la flauta y a ella la guía el amor. «¡Gracias al poder de la música, / atravesamos alegres / la sombría noche de la muerte!». Final feliz. Telón. Aplausos.

Luz, espacio, obscuridad y tiempo. La estética expandida de Miguel Ángel Murgueytio y el arte tecnológico contemporáneo en Ecuador
Authors: GARCÍA SEDANO MARCELINO
Published: October 2022

El artista ecuatoriano Miguel Ángel Murgueytio es uno de los más destacados dentro de la escena de arte tecnocientífica local. Una escena relativamente joven que tiene como característica el ser producida lejos de los lugares de referencia internacional de este tipo de manifestaciones. El análisis de la figura y obra de Murgueytio, permite examinar el estado de esta cuestión en Ecuador y las características que definen el arte contemporáneo local y las problemáticas que lo definen. Se tomarán en cuenta para esta labor en primer lugar la relación del arte local con lo global, entendiendo este concepto de manera amplia, pero como emanación de las culturas hegemónicas. También la realidad del mercado laboral de la cultura y la necesidad constante por parte de artistas de compaginar trabajo comisionado con obra personal y, por último, la relación de estos discursos tan propios de la modernidad con elementos culturales ancestrales.

Published: October 2022

El autor analiza un proceso artístico de coautoría, del cual formó parte, desde el punto de vista de dos fuerzas fundamentales en el proceso, el control y la imprevisibilidad. Existe una tensión entre las dos fuerzas en la creación artística. Consideramos que los actos conscientes, premeditados, predecibles y precisos aumentan el control, mientras la imprevisibilidad, en todas sus formas diferentes, lo reduce. A través del estudio del proceso creativo de la obra Metáforas: pegadas dun percorrido, 2021, de Alexandra R. Rey y Thomas Apostolou, el autor del texto (Thomas Apostolou), examina la relación del control e imprevisibilidad en el proceso creativo contemporáneo.

Hacia otra forma de inclusión artística focalizada en la singularidad
Authors: CHOUATI YASSINE
Published: October 2022

En esta comunicación, consideramos que en la aproximación a la alteridad en el arte contemporáneo existe un desinterés por ahondar en la singularidad de las diferentes experiencias artísticas de los artistas no occidentales. En otras palabras, parece que las instituciones, las estrategias curatoriales y la crítica del arte se limitan a atribuir juicios relacionados con la identidad nacional, género, religión, color, etc.; en lugar de acceder a las experiencias humanas. Nos referimos con experiencias humanas, al hecho de prestar atención al valor de la creatividad y las diferentes sensibilidades existentes. Cabe señalar en este sentido que nuestro enfoque surge desde una perspectiva de investigación que combina la reflexión teórica y la creación artística, donde el objetivo es vislumbrar brevemente los defectos de las iniciativas de inclusión para proponer estrategias creativas que impliquen la superación de la mirada antropológica aplicada al arte.

Borrowings Kṣuta-/kṣut- (“Inimical”) and Vidumāla- (“Retrograde”) in Sanskrit Astrological Texts, and the Representation of Semiticʿayn in Similar Loans
Authors: Wikander Ola
Published: October 2022

This short article deals with the etymologies of two Perso-Arabic loans that function as technical terms in Tājika (Indian astrology imported from the Perso-Arabic cultural area), both appearing in the works of the 13th century CE astrological author Samarasiṃha. The terms are kṣuta-/kṣut- (“Inimical”) and vidumāla- (“Retrograde”) - the meanings of both have been clear for some time, but the article elucidates their exact etymologies, and uses them to argue a rather complex mode of scientific/scholarly transmission, possibly involving as many as four languages: Arabic, Persian, Old Gujarati (or other northern Indo-Aryan vernaculars of the time), and finally Sanskrit. Finally, the article discusses the renderings of the voiced pharyngeal fricative in loans of this type in the light of early Modern Persian orthography and phonology.
Identification of demographic crises and evaluation of their intensity in the Kujawy region (Central Europe) in the 19th century
Authors: Drozd-Lipińska Alicja , Bartczak Arkadiusz , Krzemiński Michał , Dziki Tomasz
Published: October 2022

Mortality crises are periods of unusually high mortality resulted from a combination of epidemic episodes, climatic phenomena, historical events and sociopolitical factors. The most pronounced setback in the methodology applied to analyse mortality rates of historical populations is the inability to establish their size.
Reference publications do not provide unambiguous measures of the intensity and scale of mortality crisis periods. This problem was approached with the use of the Standardised Demographic Dynamics Rate (SDDR) whose value provides information about the condition of a population, disregarding the size of the group. Demographic crises were indicated and identified among the population living in the 19th century in central Poland in the rural parish. The analysis was based on data obtained from parish registers, made use of the measure expressing the ratio of the number of births to the number of deaths, without using the size of the group.
Results obtained from the analysis of data were set against the information about events causing a sudden growth in mortality derived from the widely-accessible literature. Value of the Standardised Demographic Dynamics Rate (SDDR) provides information aboutthe condition of a population, disregarding the size of the group. Nevertheless, only by combining the statistically obtained data with the information derived from written records it is possible to attempt to answer the question of the possible root cause of a demographic crisis.

Background: Primary percutaneous coronary interventions (PCI) in acute coronary syndrome (ACS) with transradial access (TRA) are associated with the risk of local complications, such as occlusion of the radial artery (ORA), hematomas, pseudoaneurysms, and arteriovenous fistulas.
Aim: To perform comparative assessment of clinical efficacy and safety of the TRA and dorsopalmar (modified distal) radial access (DpRA) for primary percutaneous coronary intervention in in-patients with ACS.
Materials and methods: This was a randomized, dynamic, single-center, prospective study in two parallel groups. The patients were randomized in a 1:1 ratio into two groups with different types of the radiation access: TRA (n = 100) or DpRA (n = 100). TRA was made at the distal third of the forearm and DpRA on the dorsal palm surface. After the access zone was evaluated by angiography, the pressure bandage was placed on the zone for 6 hours for hemostasis. The comfort of hemostasis was assessed by the Gaston-Johansson 10-point verbal-descriptive pain rating scale. On the 57th day after PCI, all patients were examined with palpation and ultrasound assessment of the access artery.
Results: The number of attempts, average duration of the radial artery puncture, duration of the fluoroscopy procedure, and the conversion rate did not depend on the access type. The scoring of the subjective hemostasis comfort showed a significant advantage of DpRA over TRA (6.4 [4; 10] in the TRA group vs 1.7 [0; 6] in the DpRA group, p 0.001). The rate of EASY III hematomas was 15 (15%) in the TRA group vs 3 (3%) in the DpRA group (p = 0.004). There were no EASY IVV hematomas, occlusion of the radial artery of the forearm, pseudoaneurysms and arteriovenous fistulas in the DpRA group. The diameter of the forearm radial artery was significantly larger than the diameter on the dorsal palm surface in the patients of both groups, regardless of the type of access chosen (2.75 0.32 mm and 2.38 0.36 mm in the TRA group, p 0.001; 2.84 0.38 mm and 2.45 0.36 mm in the DpRA group, p 0.001). In the patients with access conversion in both groups, the diameter of the radial artery at both levels was less than the average one.
Conclusion: DpRA for PCI in ACS patients is a safe alternative to conventional radiation access. Ultrasound examination of the radial artery diameter in its distal and forearm parts before PCI could reduce the conversion rate.
Role de Save Our Souls (SOS) Villages D’enfants Burundi dans le Processus du Developpment Communautaire: Cas des Associations Villageoises D’epargne et de Crédit (AVEC) initiées par son Programme de L’amélioration des Conditions de Vie des Ménages de Buju

Cet article met en lumière le rôle de SOS villages d’enfants Burundi dans le processus du développement communautaire : Cas des AVEC initiées par son Programme de l’amélioration des conditions de vie des ménages de Bujumbura. Il montre que malgré tous les efforts fournis par les AVEC pour aider les pauvres à accéder au crédit, leur revenu reste toujours faible. La majorité de la population n’arrive pas à satisfaire ses besoins fondamentaux entre autre les besoins liés à l'éducation, à la santé, à l'emploi, au logement et à la sécurité sociale surtout à l’accès aux services financiers et cela est dû au manque de capital financier. Face aux problèmes des conditions de vie des familles pauvres de Bujumbura qui se posent actuellement, plusieurs actions ont déjà été amorcées pour tenter, tant soit peu, de les résoudre. Pour y arriver, nous avons opté pour des approches qualitative avec l’usage du guide d’interview et quantitative avec l’usage d’un questionnaire administré de façon directe aux membres des AVEC de SOS Villages d’Enfants Burundi; aux non membres des AVEC; aux personnes formant le comité de gestion des AVEC et à la coordinatrice du projet ont été sélectionnés. Face à cette situation des conditions de vie des ménages de Bujumbura, cet article met en évidence les contraintes auxquelles font face le SOS Villages d’Enfants Burundi dans leur mission de l’amélioration des conditions de vie des ménages de Bujumbura, comme le manque de financement essentiel et la population galopante qui n’évolue pas avec l’économie du pays.
COBRA: QUANDO A LINGUAGEM MUDA DE PELES OU CARNAVALIZA-SE BARROCAMENTE
Authors: Caputo Irma
Published: October 2022

O presente artigo pretende propor um percurso de análise da obra Cobra (1972) de Severo Sarduy sob o prisma da escrita performativa, isto é, uma prática de escrita literária que servindo-se de procedimentos estéticos diversos, organiza o material verbal de forma a englobar aspectos e características da performance, desatendendo parcialmente as expectativas de linearidade, legibilidade e inteligibilidade imediata, próprias de uma visão essencialista e funcional de linguagem. O texto resultante de tais práticas de escrita configura-se como anticanônico e híbrido pela forma textual mutante, a qual será abordada também como um exemplo de neobarroco latino-americano e de estética carnavalesca, por se apropriar de elementos dialógicos ambivalentes, irónicos e por vezes enigmáticos.

Introduction: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) led to changes in healthcare institutions and medical assistance. Non-SARS-CoV-2 related diseases were indirectly affected by the pandemic. Nonetheless, their treatment remains crucial. Cardiovascular conditions such as acute coronary syndrome (ACS) are common, and it was necessary to adjust medical assistance to these diseases during the pandemic. This study aimed to assess the national impact and healthcare system response during the first wave of the pandemic in patients admitted for ACS.Material and Methods: Multicenter retrospective study based on the Acute Coronary Syndrome Portuguese National Registry between the 1st January 2016 and the 28th February 2021. Two groups were defined: the previous year to the SARS-CoV-2 pandemic (March, April, May and June 2019) (952 patients) and the first wave of the pandemic (March, April, May and June 2020) (642 patients). Clinical course, time until reperfusion, in-hospital outcomes and follow-up at one year were compared between both periods.Results: There was a lower incidence of ACS between March and June 2020 compared with the same period in 2019, with a reduction of 32.6%. There were no statistically significant differences between the two periods regarding patient demographic characteristics (except for a higher prevalence of familiar cardi vascular history and chronic obstructive pulmonary disease in 2020 and higher prevalence of diabetes in 2019), clinical features, clinical management, in-hospital major adverse cardiac events, mortality and readmission at one-year follow-up. There was a trend towards longer delays until reperfusion, yet without statistical significance. The patients that developed ACS during the first wave of the SARS-CoV-2 pandemic were less often referred to percutaneous coronary intervention centers (p = 0.034) and were more frequently transferred to another hospital (p < 0.001).Conclusion: During the first wave of the SARS-CoV-2 pandemic there was a nationwide reduction in demand of healthcare services due to ACS events. Even though the Portuguese healthcare system was under strain and forced to divert resources and medical assistance towards the pandemic management, it was capable of responding adequately to ACS.
The shadow fathers: Barriers to whole family approach in social work?

Published: October 2022

Objective: The paper aims to explore the barriers to father involvement in family social work at the personal, cultural, and structural levels, and their interconnectedness to answer the main research question of how gendered constructions of mothers and fathers in social work affect the involvement of fathers in interventions. Background: This paper contributes to debates about fathers in social work by examining gendered constructions of fathers in social services for families with children in the Czech Republic. The problem is viewed from the perspective of social constructionism, anti-oppressive practice, and the whole family approach. Method: To meet the objective, we used a qualitative research strategy. 44 in-depth interviews with social workers, mothers, and fathers were carried out. After that, three focus groups with 21 social workers were formed. Results: The results show that mothers and fathers are treated differently in social work, and femininity and masculinity are perceived as dichotomous opposites. This hinders fathers' involvement in family services and puts responsibility for solving family problems to mothers. Conclusion: Most of these barriers at the micro- and mezzo-levels are in some way related to system barriers at the macro-level, which are often shaped by gender discourses.
Conhecimento matemático para ensinar álgebra

No presente artigo tem-se por objetivo compreender e caracterizar o conhecimento profissional para o ensino da Matemática e da Álgebra que está presente nos documentos curriculares vinculados à Licenciatura em Pedagogia. Para a operacionalização do estudo foi viabilizada uma pesquisa documental que reconheceu que os documentos curriculares preveem o desenvolvimento do conhecimento matemático para o ensino na Licenciatura em Pedagogia, mas não caracteriza as unidades temáticas presentes na Base Nacional Comum Curricular. No que tange ao ensino da Álgebra, durante a análise dos documentos norteadores gerais nota-se a ausência dessa unidade temática de forma explícita nesses documentos, o que indica que evidências do que realmente é e como é o trabalho com essa unidade só pode ser observada no planejamento do formador.

Bioengineering of Escherichia coli Nissle 1917 for Overproduction and Excretion of Spermidine, a Key Metabolite in Human Health
Authors: Caffaratti Clement , Plazy Caroline , Cunin Valérie , Toussaint Bertrand , Le Gouellec Audrey
Published: October 2022

Over the past decade, studies have demonstrated the importance of bioactive metabolites derived from the microbiota in the regulation of physiological processes essential for homeostasis and the maintenance of human health. Strategies to modulate the production of these metabolites in the gastrointestinal tract hold promise for combating dysbiosis or inflammatory bowel disease. Metabolic engineering of probiotics could be one of these solutions. In this work, we engineered Escherichia coli Nissle 1917 (EcN) to overproduce spermidine, a metabolite known for its anti-immunosenescence and anti-inflammatory properties. Using a rational synthetic biology approach coupled with analysis by high resolution mass spectrometry, we designed in several steps and validated engineered probiotics overproducing and excreting spermidine. Based on our results, we first added the enzyme substrate putrescine and showed the overproduction of spermidine and decided to add a transporter limiting the production of the acetylated form of spermidine. Next, we used untargeted metabolomics to study the impact of engineering on the central metabolism of E. coli Nissle. Untargeted metabolomics appears to be a good strategy to optimize the metabolic engineering of probiotic strains and thus accelerate their development for personalized medicine.

The unprecedented growth of publicly available SARS-CoV-2 genome sequence data has increased demand for effective and accessible SARS-CoV-2 data analysis and visualization tools. A majority of the currently available tools either require computational expertise to deploy or limit user input to pre-selected subsets of SARS-CoV-2 genomes. To address these limitations, we developed ViralVar, a publicly available, point-and-click webtool that gives users the freedom to investigate and visualize user-selected subsets of SARS-CoV-2 genomes obtained from the GISAID public database. ViralVar has two primary features that enable: 1) visualization of spatiotemporal dynamics of SARS-CoV-2 lineages, and 2) structural/functional analysis of genomic mutations. As proof-of-principle, ViralVar was used to explore the evolution of the SARS-CoV-2 pandemic in the USA in the pediatric, adult, and elderly population (n > 1.7 million genomes). While the spatiotemporal dynamics of variants did not differ between these age groups, several USA-specific sublineages arose relative to the rest of the world. Our development and utilization of ViralVar to provide insights on the evolution of SARS-CoV-2 in the USA demonstrates the importance of developing accessible tools to facilitate and accelerate large-scale surveillance of circulating pathogens.

Competition between cotton, winter, and summer crops is the greatest obstacle for plant breeders in Egypt. Breeders are thus seeking early maturing, high-yielding cultivars that are suited for planting following winter crops. This study was conducted during the 2016 and 2018 growing seasons at the Sakha agriculture research station, Egypt's agricultural research facility. This research used breeding material from the F2, F3, and F4 generations that resulted from crossing Giza 94 and Uzbekistan. During the 2016 growing season, the F2 population was cultivated, and the top 5% of the F2 population (75 plants) were chosen based on the selection criteria. In the summer of 2017, the F3 families were cultivated, and 5% of the superior F3 families were chosen to become the F4 fam-ilies, which were planted in the summer of 2018 at the single plant and bulk studies in a randomised full block design with three replications. The average performance of the characteristics boll weight, seed cotton yield, lint percentage, and lint index increased as generations passed from F2 to F4. In the meanwhile, the characteristic value of the first flower to open decreased, showing the accu-mulation of advantageous alleles. For all examined characteristics, the phenotypic coefficient of variance was greater than the genotypic coefficient of variation. In addition, the data demonstrated that heritability in a broad sense was greater in F4 populations than in F3 and F2 populations. With a few exceptions, the phenotypic and genotypic associations for all investigated characteristics were positive and very significant. According to the data, initial opening flowering and boll weight had a substantial impact on seed cotton output per feddan. In general, five superior families No. 9, 13, 18, 19, and 20 were chosen from the F4 population, which were more significant for yield and yield component than the commercial variety, and these genotypes may be promising for the breeding programme to develop new genotypes with superior yield.
