Gender-Based Administrative Violence as Colonial Strategy
Authors: Ruíz Elena , Berenstain Nora ,   University of Arkansas Press
Published: September 2020

There is a growing trend across North America of women being criminalized for their pregnancy outcomes. Rather than being a series of aberrations resulting from institutional failures, we argue that this trend is part of a colonial strategy of administrative violence aimed at women of color and Native women across Turtle Island. We consider a range of medical and legal practices constituting gender-based administrative violence, and we argue that they are the result of non-accidental and systematic production of population-level harms that cannot be disentangled from the goals of ongoing settler occupation and dispossession of Indigenous lands. While white feminist narratives of gender-based administrative violence in Latin America function to distance the places where such violence occurs from the ‘liberal democratic’ settler nation-states of the U.S. and Canada, we hold that administrative forms of reproductive violence against Latin American women are structurally connected to efforts in the U.S. and Canada to criminalize women of color and Indigenous women for their reproductive outcomes. The purpose of these systemically produced harms is to sustain cultures of gender-based violence in support of settler colonial configurations of power.

Published: September 2020

Water footprint (WF) is an indicator of fresh water consumption that considers in its calculation the used water volume during the production process. The research objective was to evaluatecotton, corn and soybean crops WF at the São Lourenço-MT sub-basin area. The water consumption was quantified in Green Water Footprint (WFGreen) and Gray Water Footprint (WFGray). The WFGreen of each crop was calculated by the evapotranspiration value throughout the crop growing period. The WFGray was counted separately for a group of nine agrochemicals. In the current scenario there is sustainability in the sub-basin of the São Lourenço river, but with the agricultural current area expansion rate, in 2025 there will be no such sustainability.
Four generalized Weibull distributions: similar properties and applications
Authors: Ortega Edwin Moises Marcos , Prataviera Fábio , Cordeiro Gauss Moutinho
Published: September 2020

We derive a common linear representation for the densities of four generalizations of the two-parameter Weibull distribution in terms of Weibull densities. The four generalized Weibull distributions briefly studied are: the Marshall-Olkin-Weibull, beta-Weibull, gamma-Weibull and Kumaraswamy-Weibull distributions. We demonstrate that several mathematical properties of these generalizations can be obtained simultaneously from those of the Weibull properties. We present two applications to real data sets by comparing these generalized distributions. It is hoped that this paper encourage developments of further generalizations of the Weibull based on the same linear representation.

Published: September 2020

The aim of this study was to assess the oxidative stability (OS) of oils Brazil nuts, coconut and palm, as well as determine the quality parameters: acid value (AV), humidity, ash content, and fatty acid profile (FA). According to the results the oils of Brazil nuts, coconut and palm oil showed AV of 2.02, 2.49 and 5.92 mg KOH g-1, humidity of 0.060, 0.101 and 0.040% and ash of 0.010, 0.005 and 0.009%, respectively. Considering FA, the Brazil nut oil showed greater amount of linoleic acid (38.61%) and oleic acid (31.95%) in its composition. While in coconut oil the major amounts were lauric acid (35.22%) and myristic (17.43%) and in the palm oil, oleic acid (48.30%) and palmitic (28.67%). The OS analysis showed that there is a relationship between the FA chemical composition of each oil and oxidative stability index (OSI) that relates to the resilience capacity to lipid degradation.

Published: September 2020

The production of solid waste in Brazil has increased considerably, with the creation of a great number of dumps. Several socio-environmental impacts results from this inadequate disposal. The present work had the objective to evaluate, based on environmental, economic and social criteria, possible favorable areas for the installation of a sanitary landfill in the Metropolitan Region of Belém (MRB), state of Pará. To this end, data were processed using a Geographic Information System (GIS). A map with potential areas for landfill installation in the MRB was created, based on the criteria and weights assigned to each variable through map algebra methods. The results showed four areas in the municipality of Santa Bárbara and Santa Izabel as favorable for installation of the project, with characteristics that meet the criteria established in legislation (NBR 13896/1997).

Published: September 2020

Methane (CH4) is one of the main greenhouse gases. An important source of CH4 emission is flooded rice paddy. In this paper, the Eddy Covariance methodology was used to estimate the surface fluxes of CH4 in a flooded rice paddy in the Southern Brazil (lat: -30.2771 N; long: -53.1479 W; altitude - 40.5 m). In the event of low turbulence, this method can generate unrealistic flux data. In this situation, it is recommended remove the flux of the dataset. In general, the friction velocity (u*) is used to remove CH4 flux in low turbulence situations. However, u* is a flux and the use of the standard deviation of vertical velocity fluctuations (σw) can be an alternative. The objective of this work is to analyze the behavior of CH4 flux with friction velocity (u*), with the standard deviation of vertical velocity fluctuations (σw), and with atmospheric and soil variables in a flooded rice paddy.

Published: September 2020

This study analyzes the thermal variability of soil in a natural pasture area in the Pampa biome in southern Brazil.  The dataset was collected at the experimental site located in Santa Maria - RS (SMA). The hybrid model is based on an analytical solution of the heat conduction equation and in experimental data. Soil thermal properties, thermal conductivity (), and thermal diffusivity () were estimated for different combinations of the clearness index and soil moisture. The  values obtained in this study are the lowest in dry conditions and the highest ones in wet conditions. From the average daily cycles, the hysteresis phenomenon is more pronounced between soil heat flux () and global solar radiation for all clearness index ranges. The present analysis identiﬁed better relations between  and temperature soil temperature at 0,05 m and air temperature. Hysteresis exhibit the same behavior when data are classiﬁed by soil moisture. The results obtained here can be used in models that intend to represent the behavior of energy exchange between the soil-surface atmosphere.
Avaliação da previsão de estabilidade na camada atmosférica de superfície do modelo WRF e efeitos na previsão de geração eólica no Uruguai
Authors: Orteli Sofía , Cazes Gabriel
Published: September 2020

This work evaluates forecasts of vertical stability of the surface atmospheric layer obtained with the WRF regional model in Uruguay, for different times of the day and seasons of the year. The temperature and humidity values obtained from the model outputs and from field measurements at different heights in an anemometric tower allow to calculate the vertical gradient of virtual static stability both for predictions and field measurements. With the results obtained, it was possible to know the behavior of the WRF model in relation to the stability of the surface layer, which is closely related to the wind potential that may exist at different times of the day. In this way, a possible relationship between the systematic errors of forecasts of wind power and surface layer stability in Uruguay can be proposed.
Análise da influência do uso da parametrização cúmulus na simulação do vento com diferentes parametrizações de camada limite planetária
Authors: Afonso Eliseu Oliveira , Acevedo Otávio Costa , Puhales Franciano Scremin
Published: September 2020

The present work aimed to evaluate the influence of use the cumulus parameterization on the wind shift with two dynamic planetary boundary layer parameterizations using the Weather Research and Forecast model. Studies on model simulations using PBL parameterizations in tropical regions are generally rare, mainly due to the lack of experimental observations. This work is part of a project developed in partnership betweenTPP Pecém II, TPP Parnaíba I, Parnaíba II and III generation of S.A. Energy and the Federal University of Santa Maria-UFSM. The Parnaíba Thermoelectric Power Plant (UTE) complex is located in Santo Antônio dos Lopes city in Maranhão and is operated by the Brazilian company Eneva. As energy production through the combustion of natural gas produces wastes that are released into the atmosphere, environmental regulatory bodies demand that verification and control measures be taken, such as chemical species monitoring. Therefore, a good description of the atmosphere is fundamental for the good performance of chemical species dispersion models. Four automatic weather stations were used to validate the model simulations. The model had difficulty reproducing the wind magnitude values as observed.

Published: September 2020

Brazil is the main sugarcane producer in the world, which is intended for various purposes, from food to power generation. Soybean cultivation in areas of sugarcane under renewal has been growing progressively in Brazil. Quantifying energy fluxes at different stages of this process is essential for better management. The work was carried out in Piracicaba city, with the objective of analyzing the behavior of energy fluxes and the closing of the energy balance in a sugarcane renewal area with a fallow period followed by soybean cultivation. The latent and sensitive heat fluxes were obtained with the “Eddy covariance” method. The closing of the energy balance in the fallow period with straw-covered uncovered and soybean-cultivated soil presented a correlation coefficient of 0.88, 0.78 and 0.71, respectively. In the period without cultivation, the sensible heat flux was predominant in relation to the latent heat flux, varying according to the rainfall regime. The presence of straw under the soil in the fallow period affected the latent heat flux. With soybean cultivation, the latent heat flux surpassed the sensible heat flux.

Conversas com um Espelho: Transbordamentos no ensino da arte
Authors: Diederichsen Maria Cristina
Published: September 2020

Este artigo visa dar alguns passos por entre as descontínuas, incertas e sinuosas paisagens da contemporaneidade, onde o virtual e o real se interpenetram, diferentes olhares se cruzam, múltiplos discursos se tocam. Uma conversa acontece entre uma professora de arte e um espelho, pensando o ensino da arte como possibilidade de criação de outros devires, outras sensibilidades, de novas maneiras de viver, de ser-em-grupo e de potencialização poética do processo de aprender. Diante/dentro da crise em que nos encontramos como inventores de mundos e construtores da herança que, inevitavelmente, deixamos aos que nascem depois de nós, o ato artístico pode criar estranhamentos, gerar descontinuidades, olhares enviesados, questionar as maneiras habituais de percepção, e, como quem vive cada momento, cada vez como a primeira vez, inaugurar um novo tempo, produzindo diferenças, liberdades e possibilidades de encontro.
Théories, terrains, témoins : des pratiques de recherche à la construction d’une variété de langue
Authors: Arrighi Laurence
Published: September 2020

Dans le cadre d’une recherche ayant pour objet les discours d’autorité sur la langue en Acadie, cette étude prend comme terrain un corpus d’importantes contributions scientifiques à la linguistique acadienne. L’article s’attache aux actions mobilisées par le chercheur, la chercheuse pour constituer l’objet qu’il entend décrire, une série d’opérations sélectives qui conditionnent, voire constituent l’objet regardé. L’analyse de ce discours savant s’appuie sur les outils de la sociolinguistique critique en proposant une analyse critique de faits, de processus et d’événements. C’est par les travaux qui lui sont consacrés qu’un ensemble de pratiques linguistiques est institué en variété de langue. Cette imputabilité de la recherche dans la construction des objets linguistiques a déjà été signalée, mais reste peu documentée. Ce travail entend y participer. L’étude s’arrête sur de grands chantiers de la linguistique acadienne, des thèses de doctorat de Geddes (1908) à Perrot (1995) en passant par Massignon (1962), Flikeid (1984) et Péronnet (1989). Dans la mesure où ces travaux ont joué un rôle prépondérant dans la définition des pratiques linguistiques comme acadiennes, ces travaux permettent d’envisager diverses postures méthodologiques et d’éclairer quelques enjeux des choix effectués afin de décrire une variété de langue.
Les réclamations collectives en éducation au xixe siècle chez les Acadiens du Nouveau-Brunswick
Authors: Migneault Gaétan
Published: September 2020

Plusieurs auteurs attribuent aux Acadiens et à leurs instituteurs l’absence d’un esprit de groupe et de solidarité d’appartenance avant la renaissance des années 1880. Par contre, il n’est pas dit clairement sur quoi se fondent ces observations. À l’aide des pétitions présentées par la minorité francophone en rapport au système scolaire, cet article vérifie la conclusion tirée par cette doctrine. Différents types de pétitions présentées au fil des ans sont étudiées dans ce texte. Elles sont produites au nom de la communauté ou signées par un grand nombre de ses membres. En outre, leur contenu est souvent éloquent. Elles permettent de remettre en question l’allégation disant que les Acadiens n’avaient aucun esprit de groupe, solidarité d’appartenance ou conscience de former une coexistence humaine particulière. Elles révèlent plutôt une activité intéressante dans un domaine que tous estiment important. Toutes les mesures recensées remontent à la période d’avant les conventions nationales acadiennes.
Dans le sillage de « l’Acadie en France » : Les chemins de la liberté de Jean Mohsen Fahmy
Authors: Viau Robert
Published: September 2020

Véritable saga en deux volumes, le roman historique Les chemins de la liberté (2013-2014) de Jean Mohsen Fahmy porte sur les séquelles de la Déportation, l’acclimatation des Acadiens rapatriés en Poitou et leur détermination à retrouver leur pays d’origine. Le roman de Fahmy décrit admirablement bien la progression des Lumières en France et en Amérique, et rappelle un épisode méconnu de l’histoire acadienne. Roman historique qui se déroule sur les deux rives de l’Atlantique, Les chemins de la liberté établit des liens entre deux communautés et démontre que l’héritage franco-acadien, cette « mémoire en partage », mérite d’être mieux connu et développé.

Dans cet article, nous analyserons le thème de « l’Acadie en France », ses bases historiques, ses multiples manifestations et ses répercussions dans le monde associatif. Nous porterons aussi une attention particulière à la querelle du prix France-Acadie 2014, querelle suscitée à la suite de l’attribution du prix au roman de Fahmy, et qui va engendrer une remise en question des critères d’attribution du prix. Le roman de Fahmy reprend en les modernisant les thèmes traditionnels des romans de la Déportation, décrit les soubresauts qui ont mené à la liberté en France et en Amérique, et garde intact l’idéal d’un paradis qui, bien que perdu, ne cesse d’attirer et de susciter des quêtes… et des querelles.

Cet article examine la diversité des parcours après la scolarité primaire chez des enfants rwandais·es afin de comprendre le sens qu’elles·ils donnent à ces parcours et leur manière de s’y adapter ou de s’y opposer. Utilisant une partie des résultats d’une recherche doctorale faite entre 2015 et 2018 et portant sur l’expérience scolaire des élèves en 6e année du primaire dans les écoles publiques de Kigali, cet article montre que les parcours des enfants interrogé·e·s après leur scolarité primaire sont différenciés en fonction de leurs performances scolaires et de leur origine sociale, et ce, d’autant plus que l’orientation a lieu tôt. Il montre également ce qui favorise ou ce qui entrave leur accès à la culture scolaire et leur appropriation de celle-ci, en insistant sur les politiques, les pratiques éducatives et les conditions socioéconomiques familiales.

Published: September 2020

3D printing strategies have acquired great relevance toward the design of 3D scaffolds with precise macroporous structures, for supported mammalian cell growth. Despite advances in 3D model designs, there is still a shortage of detection tools to precisely monitor in situ cell behavior in 3D, thereby allowing a better understanding of the progression of diseases or to test the efficacy of drugs in a more realistic microenvironment. Even if the number of available inks has exponentially increased, they do not necessarily offer the required functionalities to be used as internal sensors. Herein the potential of surface‐enhanced Raman scattering (SERS) spectroscopy for the detection of biorelevant analytes within a plasmonic hydrogel‐based, 3D‐printed scaffold is demonstrated. Such SERS‐active scaffolds allow for the 3D detection of model molecules, such as 4‐mercaptobenzoic acid. Flexibility in the choice of plasmonic nanoparticles is demonstrated through the use of gold nanoparticles with different morphologies, gold nanorods showing the best balance between SERS enhancement and scaffold transparency. Detection of the biomarker adenosine is also demonstrated as a proof‐of‐concept toward the use of these plasmonic scaffolds for SERS sensing of cell‐secreted molecules over extended periods of time.

Proximal interstitial deletions of chromosome 9p13 have been described only in a few patients with developmental delay, moderate intellectual disability, craniofacial dysmorphism, short stature, genital anomalies, and precocious puberty. To corroborate and expand these findings, we report on two novel syndromic male patients with 9p13 deletions suffering from a similar form of tremor and compare them with literature data. Despite genomic variability in deletion sizes, all patients displayed homogeneous dysmorphism and clinical manifestations, including very invalidating tremor. Furthermore, we outlined a region of around 2 Mb shared in common by all patients with nearly 70 genes, among which NPR2 might have a role in the phenotype. These data delineate interstitial 9p13 deletion syndrome with tremor as a major feature.
Face Masks Are Beneficial Regardless of the Level of Infection in the Fight Against COVID-19
Authors: Burnett Mervin L. , Sergi Consolato M.
Published: September 2020

Coronavirus disease 2019 (COVID-19) due to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is currently a global pandemic that has affected over 7 million people worldwide, resulting in over 400,000 deaths. In the past 20 years, they have been several viral epidemics that were primarily transmitted by respiratory droplets. The use of face masks is proven to be effective in protecting health-care workers as they perform their duties. Still, there is limited evidence about whether the widespread use of face mask would be very useful in protecting the general population. This study aimed to conduct a review to determine if face masks would be beneficial in the general population as a means of reducing the spread of COVID-19. The widespread implementation of wearing face masks by the general population is challenging due to a variety of factors. However, the extensive use of cloth masks in conjunction with other preventative measures such as social distancing and handwashing can potentially reduce the risk of transmission of COVID-19.
Racial complaint and sovereign divergence: the case of Australia's first Indigenous ophthalmologist
Authors: Singh David
Published: September 2020

Abstract
This is a reflective piece that examines the nature of racial complaint with reference to Dr Kris Rallah-Baker's concerns about the racism that characterised his medical education. It will further examine the anti-racist campaign that sprung up in support of Rallah-Baker with a view to illustrating the limits of conventional critical race theory in understanding the course of events. Using the work of Aileen Moreton-Robinson, Gramsci and Stuart Hall, it will be argued that the Rallah-Baker case illustrates that Australian hegemonic formations can never quite command total legitimacy because sovereign formations, anti-racist in outlook, erupt with a frequency and facticity that lay bare the conceit of settler-colonialism. In so doing the paper will work towards an understanding of the critical Indigenous/race paradigm that goes beyond critical race insights borne of other places and experiences. As will be seen, what followed Rallah-Baker's complaint, the campaign that supported him and the concessions finally won was not, as critical race theory is wont to claim, a case simply of ‘interest convergence’; rather it was, I propose, an example of ‘sovereign divergence’.
Conscientization in the Indian Classroom: An Experiment in the Critical Learning of Postcolonial Literature
Authors: Deb Nilanjana
Published: September 2020

The article tells the story of a pedagogical experiment that the author conducted in collaboration with final year master’s students in Kolkata, India. The aim was to “open up the classroom,” adapting Brazilian educator Paolo Freire’s notion of critical pedagogy to an Indian context. The diverse group of students who participated in this experiment had a high degree of political consciousness regarding issues of gender, caste, sexuality, disability, and class due to the university’s history of student activism. Most students had already read a fair amount of postcolonial literature and theory. Postcolonial literature syllabus as it had conventionally been taught would not be able to engage these restive students or be relevant to their lived experiences. The experiment on classroom democratization and collaborative teaching would demonstrate to the future college teacher one kind of interventionist approach for raising student awareness in the Indian classroom.
Teaching Comparative Literature in English(es): Decolonizing Pedagogy in the Multilingual Classroom
Authors: Kaiser Birgit Mara
Published: September 2020

This article reflects on the challenges that arise when the comparative literature classroom, especially in the Netherlands, is increasingly multilingual and simultaneously increasingly monolingual in its focus on English as a primary language. In view of moving comparative literary studies beyond its Eurocentric framework, what opportunities lie in teaching translated texts in “English(es)” in such a multilingual setting? What are the effects of such an interplay of mono- and multilingualism in view of a commitment to decolonizing the literary curriculum and pedagogical practice? What attention to language and linguistic difference might be available given the diverse linguistic and cultural literacies of students? Less interested in questions of translating texts, the article pursues how teaching literary texts in translation can foster listening to linguistic difference and encourage relational attunement when degrees of literacy and illiteracy are shared at varying levels of competence across students and teachers.
Introduction to Special Issue on Literature Pedagogy Confronting Colonialism
Authors: Kortenaar Neil ten
Published: September 2020

Postcolonial literary scholars often write about challenging traditional canons and Enlightenment ideas, but that challenge too often remains at the level of content and of ideas. We also need practical change to the university classroom, our curriculum, our syllabi, our pedagogy. And we need to be in dialogue with our colleagues teaching British or American or European literature who also want to decolonize their classrooms. There need to be fora where we can discuss the questions and problems we face in our classrooms and the strategies we have developed in response. These papers arise from an ongoing collaboration across institutions to discuss what we as teachers of literature can do differently and better.
The power of culture: the gendered impact of family structures and living arrangements on social networks of Chinese older adults
Authors: Zhao Menghan , Yang Fan , Zhang Youlang
Published: September 2020

Most of the extant literature on the fertility history and social networks of older adults has focused on advanced societies. Nevertheless, a limited number of studies have explored how culturally preferred family structures or living arrangements are related to older adults’ social networks in developing societies. This study examined these issues in the Chinese context and paid particular attention to the filial piety and preference for sons dominating Chinese society. Using nationally representative data of adults aged 60 and over from China Longitudinal Aging Social Survey in 2016, we constructed family and friend network scores following previous studies and developed linear models using multiple imputation for the missing data. The results suggested that childless older adults were the most disadvantaged in receiving support from family networks. Despite China's patrilineal culture, daughters were important sources of support. In terms of friend networks, older men who had no sons were least likely to receive support while co-residing with a partner and a son(s) might benefit them. Further analysis revealed that older rural women, but not older urban women, also had more support from friend networks if living with sons, implying urban–rural differences. Given the impact of social networks on older adults’ health and wellbeing, older Chinese people with no sons might need more support from other sources, such as aged-care programmes from public institutions, to achieve healthy ageing.
Retrograde sharp potential resembling the his-bundle electrogram: is this a case of atrioventricular re-entrant tachycardia involving twin atrioventricular nodes with the anterior node exhibiting only retrograde conduction?
Authors: Izumi Gaku , Yokoshiki Hisashi , Takeda Atsuhito
Published: September 2020

A 2-year-old male with right isomerism was referred for supraventricular tachycardias. Atrial pacing study revealed that anterograde conduction was only through the posterior atrioventricular node. During the mapping of ventriculoatrial conduction, we identified a sharp potential resembling a His-bundle electrogram with a decremental property at the anterior wall of the common atrium. Catheter ablation for the potential eliminated the anterior ventriculoatrial conduction, thereby indicating retrograde activation of the possible anterior atrioventricular node.
Rollable metamaterial screen for magnetic resonance coupling-based high-efficiency wireless power transfer
Authors: Lee Woosol , Yoon Yong-Kyu
Published: September 2020

This paper presents a rollable metamaterial screen for high-efficiency wireless power transfer (WPT) system based on magnetic resonance coupling, which operates at 4.5 MHz. The rollable metamaterial screen with a fully expanded area of 750 mm × 750 mm is located in the middle between transmitter and receiver coils and focuses the magnetic field and, by such a way, significantly improves power transfer efficiency (PTE). The metamaterial screen can be rolled up, e.g. onto the ceiling when it is not used, and thus does not require any designated space for the screen saving space. A WPT system with the rollable metamaterial screen is designed, fabricated, and characterized. Improved PTE is qualitatively and quantitatively verified by light bulb experiments and vector network analyzer measurements. The PTE of the WPT system with the metamaterial screen increases from 36 to 58.52% and 10.24 to 31.36% for the distances between the transmitter and receiver coils 100 and 150 cm, respectively. The effects of lateral and angular misalignments on the PTE of the WPT system are also studied. Obtained results show that the rollable metamaterial screen improves the PTE even at the misaligned condition.

Histological Endpoints for Nonalcoholic Steatohepatitis Trials: Lights and Shadows
Authors: Rowe Ian A.
Published: September 2020

Nonalcoholic steatohepatitis (NASH) with liver fibrosis is an increasingly important cause of liver-related morbidity and mortality. A diagnosis of NASH can only be made using liver biopsy. Liver histology also forms the endpoint for the expedited licensing strategies that have been approved by regulators to allow patients with NASH access to treatment before the impact of these on clinical outcomes is known. Validation of these histological surrogate endpoints is critical for the ongoing development of new therapies for NASH. The use of liver biopsy to define both trial entry and endpoints raises questions about the use of treatments for NASH in practice when the effectiveness of treatment will likely depend, at least in part, on the use of histology for patient selection in the real world.

Background and Aim Patient safety in the neonatal intensive care unit (NICU) is one of the highest priority issues on the health care quality agenda worldwide. Efforts are needed to improve neonatal safety in NICU. The present study evaluated the effect of educational intervention on neonatal safety.

Materials and Methods Quasi-experimental study was conducted in three major hospitals, including the health care workers in their NICU during the period of study from May 2016 to May 2018. Neonatal safety standards were evaluated using an observational checklist after its validation by a pilot study. An intervention educational program was conducted in the three hospitals, followed by a reevaluation of the standards. All staff members (58 physicians and 69 nurses) participated in the three stages of the study.

Results The interventional program resulted in significant improvement of the health care workers implementation of the general (90.6 ± 15.1 vs. 127.6 ± 7.02, p = 0.016) and specific (50.6 ± 17.1 vs. 96.1 ± 13.2, p = 0.04) Egyptian Neonatal Safety Standards.

Conclusion Training and increasing the awareness of health care workers of the neonatal safety standards can significantly increase the fulfilment of these standards in both secondary and tertiary care neonatal units.

Electromagnetic surface waves at exceptional points
Authors: Lakhtakia Akhlesh , Mackay Tom G , Zhou Chenzhang
Published: September 2020

Guided by the planar interface of two dissimilar linear, homogeneous mediums, a Voigt surface wave arises due to an exceptional point of either of the two matrixes necessary to describe the spatial characteristics in the direction normal to the planar interface. There is no requirement for either or both partnering mediums to be dissipative, unlike a Voigt plane wave which can propagate only in a dissipative (or active) medium.
Investigating the naturally occurring forms of TiO2 on electronic and optical properties using OLCAO-MGGA-TBO9: a hybrid DFT study
Authors: Dharmale Neerja , Chaudhury Saurabh , Dash Debashish
Published: September 2020

In this paper, a detailed study and analysis on the electronic and optical properties of anatase, rutile and brookite titanium dioxide (TiO2) which are the naturally occurring phases of TiO2 have been carried out. We have obtained these properties using the self-consistent orthogonalized linear combination of atomic orbitals with meta-generalized gradient approximation (MGGA) and Tran and Blaha (TBO9) as exchange–correlation under the framework of density functional theory. Obtained results on band gap value (E
g), dielectric constant and refractive index as calculated by considering the optimal value of c (system-dependent parameter) have been analyzed statistically and are found to be much closer to the experimental values and are better than the other approaches published in the literature. It is seen that optical absorption for all the three phases of TiO2 occurs in UV region of EM spectrum. Using statistical analysis in correlation with other effective methods such as mBJ, GGA + U, GGA + Ud + Up, LSD + U, GW and HSE06 functional, it is found that MGGA-TB09 gives a better description of electronic structure and optical properties with less computation time. This work provides good understanding of electronic and optical properties of TiO2, stems a foundation for its possible applications in photo catalytic activities of dye sensitized solar cells.
Plasma induced vibrational excitation of CH4—a window to its mode selective processing

Vibrational excitation of methane is believed to promote chemistry and improve product selectivity, compared to thermal conversion methods. We report on unique direct measurements of vibrational–rotational non-equilibrium in methane plasma. The non-equilibrium is sustained for 50 μs, after which the gas temperature equilibrates with the vibrational temperature at around 900 K. The plasma is generated by applying 200 μs, 30 Hz pulses of microwave radiation to methane at 25 mBar. We demonstrate that in microwave discharges, power transfer to vibrational modes of CH4 is the dominant power transfer mechanism, which leads to creation of a vibrational–translational (VT) non-equilibrium. VT relaxation is determined to be the dominant translational heating mechanism in the discharge. However, the high electron temperature at breakdown also leads to strong electronic excitation which may be responsible for some of the heating. Furthermore, we find that the CH4 vibrational levels are in equilibrium with each other due to fast intra-polyad relaxation (VV), and therefore bending vibrational modes population density is greatly in excess of stretching vibrational modes. The window of opportunity to exploit this non-equilibrium is limited by the VT relaxation timescale, which is approximately 50 μs in our experiment.

Sulphate-supplemented nitrogen, phosphorus and potassium (NPKS) fertilizer was nanoformulated through ionic gelation of chitosan (CS) and tripolyphosphate (TPP) at pH value of 5.5 to afford a series of nanofertilizers. The CS-TPP nanoparticles and CS-TPP-NPKS nanofertilizers were engineered using different dose of CS (0.125, 0.25, 0.5 and 1%) and NPKS fertilizer (20, 40 and 60 ppm). These nanoparticles were characterized through particle size distribution, zeta potential, SEM, XRD, FTIR, EDX and ICP-MS. The results revealed CS-TPP-NPKS particles with size range of 220–530 nm, polydispersity index (PDI) value between 0.2–0.5 and positive zeta potential. A preliminary evaluation of these nanoparticles along with inorganic NPK and NPKS fertilizers were conducted under greenhouse condition using maize (Zea mays L.) as a test crop. Findings from this study showed that inorganic NPKS (20:7:3:0.5) fertilizer, CS-TPP nanoparticles, and formulated NPKS nanofertilizers gave higher maize plants growth increases than NPK fertilizer and control treatments. The tallest plant (37.73 cm) and highest number of leaves (9) were recorded with the CS-TPP-NPKS nanofertilizer treatment obtained using 1% CS/NPKS (40 ppm). On the other hand, application of the nanoformulated derivative with 0.25% CS/NPKS (20 ppm) produced maize plants with superior chlorophyll content with 12.71 chlorophyll index value. A highly varied magnitude of the coefficient of variation in nutrient contents and uptake was recorded among the treatments. These results revealed that the incorporation of sulphur nutrient into NPK fertilizer and its transformation to nanoparticles have the potential characteristics for effective and productive growth of maize and sustainable agricultural activities.

Published: September 2020

This research aims to analyze volcanic clays from four different Buriram sources before and after decontamination to compare their cosmetic grades, as these clays are used as cosmetic ingredients. The volcanic clays were characterized both before and after decontamination using various techniques, namely, x-ray diffraction (XRD), flame atomic absorption spectrophotometry (F-AAS), x-ray fluorescence (XRF), thermogravimetric analysis (TGA), and the Brunauer–Emmett–Teller method. Further, the pH levels were measured using electrical conductivity measurements. Physicochemical characterization was performed by determining the percentage of organic matter and cation exchange capacity. The decontaminated clay showed the lowest percentage of organic matter and a high cation exchange capacity. After the removal of contaminants, the clay exhibited an amorphous structure. In addition, the analyses before and after contaminant removal revealed a decrease in the content of lead, nickel, selenium and copper, which were the heavy metals prohibited in cosmetics. The primary components were SiO2, Al2O3, Fe2O3, CaO, K2O, MgO, TiO2, and MnO2 considering the component for cosmetics. Microbiological tests revealed an absence of Escherichia coli, fecal coliforms, and total coliforms. These characteristics theoretically indicate that the samples are suitable for use in cosmetics. Moreover, Buriram volcanic clays show low levels of contaminants and can be used as cosmetic ingredients.
