Published: June 2022

The cutoff frequency is an important characteristic parameter of type III radio bursts. Employing the radio data of the Parker Solar Probe (PSP) in the encounter phases of its first five orbits, our previous work revealed that the maximum probability distribution of the cutoff frequency f

lo
(∼680 kHz) is remarkably higher than that based on Ulysses and WIND (∼100 kHz) investigated by Leblanc et al. and Dulk et al. However, the main influencing factor of the discrepancy is still unknown though the possible reasons are discussed. In this study, we utilize the simultaneous observation by WIND and PSP to analyze statistically the distribution of the cutoff frequency of type III radio bursts, which had not been done before. Based on the automatic Canny edge detection and manual selection, we obtain the f

lo
of 491 (WIND) and 1194 (PSP) type III bursts from their simultaneous observations in the same solar activity period (from 2019 January 1 to 2020 July 31). The statistical results show that the dominant cutoff frequency measured by PSP (i.e., ∼700 kHz) is still significantly higher than that by WIND (i.e., ∼100 kHz). This implies that radiation attenuation is the main influencing factor for the difference in the statistical results of the cutoff frequency.

Published: June 2022

A radio-emitting tidal disruption event (AT2019dsg) is proposed as a likely counterpart to the IceCube neutrino event IC 191001A. In this work, we have revisited the Fermi-LAT data in the direction of the neutrino and confirmed no signal at the site of AT2019dsg. Instead, at the edge of the 90% confidence level error region of this neutrino, there is a γ-ray transient source associated with the blazar GB6 J2113+1121. In 2019 May, GB6 J2113+1121 was undergoing a γ-ray flare that is unprecedented since the start of the Fermi-LAT operation, with a variability amplitude of about 20 fold. Similar violent flares of GB6 J2113+1121, unobserved before, have also been detected in the optical bands. Moreover, the blazar remained in a high-flux state in the infrared bands when IC 191001A arrived, though the blazar ‘s γ-ray and optical activities have temporarily ceased. Motivated by this spatial and temporal coincidence, we suggest that GB6 J2113+1121 is a candidate to be the counterpart to IC 191001A. The jet properties of GB6 J2113+1121 are investigated, which are found to be comparable with that of neutrino-emitting blazars (candidates). A specific analysis of archival IceCube data in this direction and future observations would put further constraints on the origin of the neutrino.

Published: June 2022

INTRODUCTION: Pile excision is frequently associated with post-operative pain and prolonged hospital stay. A modern technique performed with LigaSure (LS) seems to be especially efficient when large pile tissue removal is needed.

AIM: The research compares LS pile excision with diathermy for the treatment of III-IV degree pile.

PATIENTS AND METHODS: Two hundred and eight patients with pile III or IV degrees randomized into two groups: Group one LS and group two diathermy. The study evaluates the mean post-operative time, post-operative pain, discharge date, and time return to usual works early and late complication. All patients followed up for a range (12–24) months.

RESULTS: One hundred and eight patients managed by diathermy, 100 managed by LS. The operating time is considerably shortened in LS; post-operative pain disappears earlier in LS than diathermy. In addition, the timely return to work reduces in LS, while no distinction between hospitalization and post-operative complications.

CONCLUSIONS: LS is an efficient procedure in degree III or VI pile excision. Therefore, the procedure enhances to use LS as the treatment of choice for Classes III–IV pile, even it is more expensive than diathermy operation.

Абстрактный   Цель исследования:  оценить роль спекл-трекинговой эхокардиографии в выявлении ранней дисфункции миокарда у женщин с артериальной гипертензией в перименопаузальном периоде.   Материал и методы. В исследовании приняли участие 50 женщин перименопаузального периода в возрасте от 45 до 55 лет. Перименопауза диагностировалась на основании клинического осмотра, включающего осмотр у гинеколога и исследования гормонального статуса женщины. Выборка женщин была разделена на две группы в зависимости от наличия артериальной гипертензии. В основную группу вошли 24 пациентки с артериальной гипертензией, диагностированной в перименопаузальном периоде. Перечисленные выше методы обследования также включали электрокардиографию, эхокардиографию и спекл-трекинговую эхокардиографию.   Результаты. По данным спекл-трекинговой эхокардиографии выявлены статистически значимые показатели в базально-антеропостероидном и нижнебазальном сегментах (р = 0,016; 0,001). Разница индекса массы миокарда левого желудочка была статистически значимой в сравниваемых группах (р = 0,038). ROC-анализ использовался для оценки качества полученной модели логистической регрессии. Площадь под ROC-кривой составила 0,806 ± 0,065 (95% ДИ: 0,679–0,933, p <0,001). Это указывает на «очень хорошее» прогностическое качество модели.   Заключение: в группе больных с артериальной гипертензией более чувствительны показатели базального переднеперегородочного и базально-нижнего сегментов, что может быть использовано как значимый показатель дисфункции при неизменных показателях стандартной эхокардиографии.

Published: June 2022

Social activities, economic benefits, and environmental friendly approach are very much essential for a sustainable production system. This is widely observed during the Covid-19 pandemic situation. The demand for essential goods in the business sector is always changing due to different unavoidable situations. The proposed study introduces a variable demand for controlling the fluctuating demand. However, a reworking of produced imperfect products makes the production model more profitable. Partial outsourcing of the good quality products has made the production system more popular and profitable. Separate holding cost for the reworked and produced products are very helpful idea for the proposed model. Moreover, consumption of energy during various purpose are considered. Separate green investment make the model more sustainable and eco-friendly. The main focus of the model is to find the maximum profit through considering optimum value of lot size quantity, average selling price, and green investment. The classical optimization technique is utilized here for optimizing the solution theoretically. The use of concave 3D graphs, different examples, and sensitivity analyses are considered here. Furthermore, managerial insights from this study can be used for industry improvement.
Imagen y realidad urbana en la Vista de Madrid por Michel-Ange Houasse

Published: June 2022

La Vista de Madrid por Michel-Ange Houasse constituye uno de los hitos principales en la representación de la ciudad, presentada por su aspecto de Poniente que resultaba el más impresionante y significativo por la presencia, en alto, del Alcázar Real y de otros edificios destacados. Al publicar aquí su dibujo preparatorio se analiza esa visión urbana con su realidad topográfica a través de un conjunto de fuentes visuales, se verifica la fiabilidad y precisión de cuanto describe, y se sitúa esta sutil imagen del poder en la secuencia de los “retratos” que, antes e inmediatamente después, se hicieron de esa cara, la más expresiva de Madrid como corte de la Monarquía de España.

Virtual Reality & Electronic Games for Assessment in ADHD
Authors: Doulou Aikaterini , Drigas Athanasios
Published: June 2022

In the last few years, several computerized tasks have been developed to increase the objectivity of the diagnosis of attention-deﬁcit hyperactivity disorder (ADHD). Usually, its diagnosis is based on the judgment of health professionals using a clinical history that often consists of assessment scales completed by caregivers and/or teachers. Many experts have criticized this way of diagnosing ADHD, as it tends to be subjective by both doctors and caregivers. Many researchers argue that using original digital diagnostic tools in the form of games for children with ADHD may provide much clearer diagnostic clues. A game can be enjoyed much more by children, as it stimulates creativity, sets specific goals to be completed, provides a feedback mechanism that fosters motivation, and offers measurable results. The present work investigates the use and effectiveness of electronic games, either in virtual reality environments or not, for the detection of the symptoms of ADHD.

Published: June 2022

This article deals with the problem of Berber handwritten character recognition using Extreme Learning Machine. This paradigm has gained significant attention in pattern recognition field thanks to its efficient learning speed and its high accuracy. In this paper, we have used a fast Extreme Learning Machine to recognize efficiently the Latin Berber characters. So, the proposed ELM has been trained over a Berber-MNIST dataset containing images of Amazigh alphabets. This algorithm learns much faster than traditional popular learning algorithms thanks to the use of JAX library which contains several functions to reduce the execution time of our solution. The simulation results show that the handwritten recognition system based on our developed extreme learning machine decreases computational cost and reduces the time required for the whole recognition process. Furthermore, the developed ELM achieves a high performance in terms of recognition accuracy.
IL senso dell’alterità nella Storia di Tamerlano e dei suoi successori di T‘ovma Mecop‘ec‘i
Authors: Bais Marco
Published: June 2022

The great Armenian tradition of narrative history came to an end with Step‘annos Ōrbēlean at the beginning of the XIVth c. From that time till the beginning of the XVIIth c. the role of narrative history was taken up by short chronicles and colophons, the sole exception being the History of Tamerlane and his successors (Patmut‘iwn Lank-T‘amuray ew yaǰordac‘ iwroc‘) written by T‘ovma Mecop‘ec‘i in the first half of the XVth c. T‘ovma’s account is based on a first-hand description of events directly experienced by the author or referred to him by eyewitnesses. No other sources seem to have been taken into consideration. Being a cleric, T‘ovma often refers to the attitude held by Tamerlane and his successors toward Muslim and Christian peoples under their control. Moreover from time to time he offers a glimpse into the relations between the Non-Chalcedonian Armenian Church and Chalcedonian Christianity, in particular speaking of Georgians or alluding to Roman Catholics. Nevertheless, although T‘ovma played an important role in Armenian religious life of his own time and was seriously engaged in fighting against the Roman influence on Armenian Church and in moving the catholicosate from Sis (Cilicia) back to Ēǰmiacin (Greater Armenia), no reference to these religious struggles seems to be found in his History.
Le Constitutum Constantini et l’impérialisation de l’église romaine
Authors: Ioan Mureşan Dan
Published: June 2022

La présente étude se propose de contribuer à la question de l’impérialisation de l’Église romaine à travers une analyse à nouveaux frais du contenu idéologique du Constitutum Constantini, document que E. Kantorowicz plaçait à l’origine de ce processus historique. Un panorama de l’historiographie consacrée au Constitutum Constantini permet de dégager six modèles interprétatifs en concurrence qui situent la genèse du document entre 750 et 850. Sans pour autant en ajouter un septième, cet article propose une relecture du document comme un type spécial d’acte performatif, qui historicise un modèle ecclésiologique sous l’apparence d’un document juridique impérial. Tout en reconnaissant ainsi les structures narratives qu’il contient, cela permet d’avancer que le Constitutum Constantini reste, malgré les affirmations contraires, un manifeste théologico-politique de réelle importance.
Il est fondé sur une économie de la gloire qui relie sa conception trinitaire à la potestas et dicio de l’évêque de Rome. Le document s’organise autour du concept central de summus pontifex et papa universalis, qui renverse la domination religieuse des prêtres du Capitole (identifiés avec les flamines maiores, et surtout le flamine de Jupiter) et se voit attribuer pour cela de la part de l’empereur Constantin (i.e. le pontifex maximus), nouvellement baptisé, la dimension religieuse de son autorité, symbolisée par le pontificalis apex. C’est donc ce transfert politico-religieux qui fonde essentiellement l’imitatio imperii, thème crucial que l’auteur du Constitutum emprunte à Cassiodore. Ce constat permet enfin de faire ressortir l’importance de l’idée de papa universalis, avancée par l’auteur anonyme en désaccord implicite avec l’interdit formel par le pape Grégoire le Grand de ce titre dans la pratique pontificale. Il en ressort que l’impérialisation de la papauté s’opère concomitamment avec la pontificalisation et l’universalisation de l’Église romaine.
Anselm of Havelberg as ‘ecumenist’: fiction and history
Authors: Avvakumov Yuri P.
Published: June 2022

The essay examines one of the most intriguing texts of the history of Latin-Greek encounter in the twelfth century, Anticimenon by Anselm of Havelberg. Even after the appearance of a few important studies on Anselm in recent decades, this German courtier bishop, canon regular, and theologian remains a widely-misread author. The lack of continuity in research is here particularly confusing. Despite the discovery of the non-historicity of Anticimenon made by Sieben in the 1980s, Anselm’s text is still too often read as a historical account of a real Latin-Byzantine debate. The essay builds up on Sieben’s discovery and explores the topic of the Eucharistic water in Anselm’s work which not only confirms earlier conclusions but also brings them to a new level. The author argues that the non-historicity of the Anticimenon deprives it of its status of a primary source in respect to Byzantine theology. At the same time, the study of the fictitious character of Anselm’s work makes it possible to gain new insights into the Latin theology of the mid-twelfth century. The topic of the Eucharistic water demonstrates that even such minute problem could promote discussion on issues of fundamental importance. The topics related to Eastern Christianity function in the Anticimenon as illustrations of the main concern of the entire work —the unity of faith in the plurality of ecclesiastical traditions and sacramental rites.
Anciens et nouveaux écosystèmes aquatiques : une revue sur leur fonctionnement abiotique
Authors: Donati Francesco , Touchart Laurent , Bartout Pascal , Choffel Quentin
Published: June 2022

Au fil du temps, quasiment tous les réseaux hydrographiques de la planète ont été lourdement aménagés avec des ouvrages hydrauliques transversaux à l’écoulement des cours d’eau, qui ont enrichi le panorama des milieux aquatiques continentaux créant des retenues de seuil en rivière, des étangs et des lacs de barrage. Toutefois, aujourd’hui ceux-ci sont au centre de préoccupations de politiques environnementales qui ont comme objectif leur effacement, afin de rétablir les conditions supposées antérieures à leur création. Plusieurs membres de la communauté scientifique se montrent prudents face aux résultats que ces opérations de restauration écologique devraient atteindre et ils proposent d’intégrer ces milieux aquatiques artificiels au sein des politiques environnementales, pour protéger leurs particularités et les bénéfices qu’ils apportent aux sociétés. Toutefois, pour faire cela il est nécessaire de comprendre leur fonctionnement et de développer une vision globale qui les assimile aux milieux aquatiques considérés comme naturels. Ainsi l’objectif de cet article est de passer en revue la littérature scientifique à propos de certaines caractéristiques du biotope des retenues de seuils en rivière, des étangs et des lacs de barrages et de les comparer avec celles des cours d’eau et des lacs naturels, pour voir de combien le fonctionnement des milieux aquatiques artificiels et naturels s’écarte. Les résultats de cette synthèse ont mis en avant le caractère hybride des milieux aquatiques artificiels examinés, qui croisent en même temps des traits lentiques et des traits lotiques. Cela a permis le développement d’une vision globale qui intègre les milieux aquatiques artificiels et naturels, selon un gradient de conditions abiotiques.
Les étangs piscicoles, des réservoirs de biodiversité végétale
Authors: Trintignac Pascal , Le Berre Maelle , Haury Jacques , Lambert Elisabeth
Published: June 2022

Les étangs piscicoles sont des agrosystèmes existants depuis le moyen âge pour élever du poisson. Une végétation spontanée est pourtant observée dans ces milieux. Un inventaire des macrophytes a été réalisé sur 85 étangs ou groupes d’étangs des Pays de la Loire (France) par la méthode des quadrats sur transects. Cet inventaire a permis de recenser plus de 270 macrophytes (en moyenne 55 par étang) dont 17 taxons protégés, 28 présents sur la liste rouge régionale des Pays de la Loire, et 42 figurants sur la liste des espèces déterminantes de cette région. La pisciculture extensive par ses pratiques favorise cette diversité floristique. Les étangs piscicoles sont donc également des écosystèmes humides qui jouent un rôle de réservoir de biodiversité. C’est pourquoi ces étangs et leur mode de gestion extensif doivent être préservés.

La caldera du Torfajökull et sa diversité géomorphologique (Islande)
Authors: Bussard Jonathan
Published: June 2022

La diversité géomorphologique exceptionnelle de la caldera du Torfajökull est le résultat de l’activité de plusieurs processus : le volcanisme, la géothermie, la gélifraction, l’érosion glaciaire et l’érosion fluviale, ainsi que la combinaison entre plusieurs de ces processus. Les affleurements de rhyolites et leur érosion venant alimenter un vaste sandur aux couleurs claires contrastent avec la coulée de lave noire d’obsidienne, la Laugahraun, qui date de l’an 1477. Afin de protéger les formes géothermales, la caldera est protégée depuis 1979, mais la récente augmentation de la fréquentation touristique accentue la pression humaine sur ces sites fragiles.
Enquêter sur la reconnaissance des sensibilités athées en Turquie contemporaine
Authors: Malçok Théo
Published: June 2022

Souvent réduite à une fonction d’indicateur de l’évolution des religiosités, la présence de l’athéisme dans la société turque a rarement fait l’objet d’études détaillant les modalités concrètes de ses manifestations. Le présent article propose de relever ce défi en partant du constat que la variation du degré d’exposition des sensibilités athées est façonnée par une dynamique séculaire opposant la continuité d’un déni à des tentatives de reconnaissance des exclus de l’assignation confessionnelle majoritaire. En s’appuyant sur l’armature théorique des figures sociologiques de la reconnaissance (objective, de soi, mutuelle), trois logiques sociales sont identifiées à partir d’une enquête de terrain auprès d’un éventail d’individus : sceptiques, incroyants, athées à-peu-près… La première logique est l’issue, toujours incertaine, de l’épreuve du regard normatif : situation problématique, qui peut se répéter quotidiennement, du soupçon ou de l’accusation d’apostasie, contournés, négociés ou confrontés. Les signes extérieurs des sensibilités athées sont donc labiles dans la mesure où ils se dé-jouent dans la performance de soi. Dans un deuxième mouvement biographique, la découverte ex post facto des signes intérieurs d’une sensibilité athée se réalise sur fond d’une prise de conscience d’un illettrisme religieux pour certains, attribut de classe les distinguant de la masse des croyants, ou dans le clivage qu’induit une mobilité sociale fantasmée ou effectuée, pour une partie de l’échantillon issue d’un milieu pieux. L’amplitude d’une reconnaissance mutuelle basée sur le dénominateur commun d’une sensibilité athée sera analysée dans un troisième temps comme dépendant largement des aspirations d’un mouvement associatif émergent. Porté notamment par l’Association de l’Athéisme (Ateizm Derneği), fondée en 2014, ce mouvement transforme un sentiment d’ostracisation, c’est-à-dire de déni de reconnaissance, ressenti par une partie des sans-Dieu et des sans religion, en motif de lutte. Malgré les moyens matériels, humains et symboliques mis en place, l’association semble condamnée à la marginalité dans la mesure où ses potentiels adhérents bénéficient de réseaux de resocialisation concurrents.
Disparity in Higher Education and the Need for Equitable Teaching Paradigms and Strategies
Authors: Howell Dorothy J.
Published: June 2022

The purpose of this chapter is to assist the reader in understanding the disparity that exists in higher education and the various interventions through which this disparity can be significantly reduced with a focus on Transparency in Learning and Teaching (TILT) as an effective pedagogical strategy. A case study analysis using a convenience sample of faculty from a local university is used to determine if the use of TILT in their courses increased students' final assessment scores. Institutions and instructors who engage in transparency within their courses produce students who are satisfied with their learning outcomes, which reduces disparity and increases retention and graduation rates. The results from the implementation of TILT into three courses show an overall improvement in student learning and comprehension of course content.
Implementing TILT in Business Education
Authors: Lakshminarayanan Sambhavi , Best Simon
Published: June 2022

Students accrue the benefits of college education unevenly. In particular, students from minority, underrepresented groups who are often the first in their family to go to college are likely to accrue less benefit. At the same time, the effectiveness of different pedagogies is typically not examined from their perspectives. TILT aims to rectify this by modifying pedagogical implementations, with emphasis on the two underlying principles of access and relevance. This chapter identifies common pedagogies in college business education, such as lectures, case method, and problem solving, and discusses implementation of these pedagogies in a manner aligned with TILT. The experiences of doing so at a PBI (Predominantly Black Institution) are presented.

Published: June 2022

Higher education is considered a strong driver of social mobility and of generating family wealth. However, students of top quartile income group have four times higher chance of graduating from college compared to those in the bottom quartile economic group. Pedagogical interventions such as Transparency in Learning and Teaching (TILT) are promoted in universities to provide equitable access to education to all students irrespective of their ethnic and social backgrounds. In this chapter, a qualitative analysis is conducted using autoethnographic narratives to gather the experiences of faculty members diverse in gender, age, subjective discipline, and ethnic origin, while implementing TILT framework in their respective classes at a Historical Black College and University (HBCU). This chapter consists of faculty perspectives on TILT, of using TILT during COVID-19 pandemic, and the problems they faced when implementing TILT. The chapter also includes a variety of examples on how TILT dimensions can be integrated into different subjective disciplines.
Transparency in Course Assessments
Authors: Paudel Laxmi Prasad
Published: June 2022

Transparency in Learning and Teaching (TILT) has become an increasingly popular initiative among the higher education faculty learning communities in recent years. While using this transparency initiative, instructors not only prepare and implement lesson plans and course activities to achieve course specific learning outcomes, but they also share the rationale of their actions with the students. The growing literature supports that TILT strategies provide students an equitable learning opportunity. In this chapter, the author discusses the impact of transparency on students' achievements from the students' perspectives, integrating empirical data gathered from a survey given to the students enrolled in the transparent courses. Students' responses were overwhelmingly positive indicating that transparency gave them higher motivation, better clarity with course objectives, and more fulfilling engagement with their instructor and fellow students. It was also observed that instructors experienced more productive interaction, higher level of work satisfaction, and better course grades.
A Foucauldian Perspective on Using the Transparency Framework in Learning and Teaching (TILT)
Authors: Akella Devi
Published: June 2022

Transparency in Learning and Teaching (TILT) demands educators inform their students what, where, and why they are expected to learn certain subjective content and how they will be assessed. This allows students to understand the relevance and usefulness of the subjective content covered in their classrooms and what they should do to perform better academically. Yet providing such detailed specifications can restrict students' abilities to be original, critical, and imaginative. Students are no longer able to think out of the box and go beyond current knowledge domains to create new information to transform societies. This chapter integrates the ideologies of Foucault's disciplinary power to deconstruct the totalitarian learning aspect hidden within the three-dimension transparency framework of TILT and how it may hinder the growth and development of students within higher education institutions.
Sensibility of Xanthomonas vasicola pv. vasculorum to chemicals and efficiency of the chemical control of bacterial leaf streak on corn plants

Published: June 2022

Bacterial leaf streak caused by Xanthomonas vasicola pv. vasculorum is an emerging disease for corn production around the world. However, information on management of this disease is still limited. This study aimed to determine the in vitro sensibility of X. vasicola pv. vasculorum to different chemicals and to evaluate the control of bacterial leaf streak on corn under greenhouse conditions. In vitro tests were carried out with kasugamycin, copper sulfate, copper oxychloride, copper hydroxide, cuprous oxide, bioactive copper, mancozeb, chlorothalonil, methyl thiophanate, and tebuconazole at the dosages of 1, 5, 10, 20, 50, 100, 200, and 400 μg mL−1. Four strains of X. vasicola pv. vasculorum were included in the study. The minimal inhibitory concentration for kasugamycin ranged from 50 to 200 μg mL–1, whereas to the inorganic copper compounds varied from 5 to 50 μg mL–1 and to the bioactive copper was 100 μg mL–1. Further, mancozeb and tebuconazole inhibited the bacterial growth at the dosage ranging from 5 to 20 μg mL–1 and 50 to 400 μg mL–1, respectively, depending on the X. vasicola pv. vasculorum strain. Chlorothalonil and methyl thiophanate did not inhibit the growth of the bacterium at any tested concentration. The control of bacterial leaf streak under greenhouse conditions was investigated on corn plants of the cultivar IPR 164 at the V3 phenological vegetative stage, sprayed with kasugamycin (3 mL L–1), copper oxychloride (1.5 mL L–1), bioactive copper (1 mL L–1), mancozeb (2 g L–1), tebuconazole (1 mL L–1), and chlorothalonil (2 mL L–1). The corn plants were inoculated with a 108 CFU mL–1 suspension of the RL1 strain of X. vasicola pv. vasculorum. Only copper oxychloride significantly reduced disease severity. However, this copper compound caused phytotoxicity to the corn plants at the tested concentration.

Phosphorus (P) is one of the most important elements used in fertilizing soils in tropical regions due to the low efficiency of phosphate fertilization. This work aimed to fractionate inorganic P (Pi) in tropical soils of different mineralogical compositions and to relate these fractions with their respective phosphate buffer capacity (PBC) indicators. The soils were characterized physically, chemically and mineralogically. Additionally, we evaluated the P concentration that remained in solution of soil after equilibrium was met; this was termed P remaining (P-rem). In general, the Pi fractions of soils did not correlate with the PBC indicators. The P-H2O fraction showed a negative correlation with the P-Al fraction. Ferric minerals did not influence P fixation. P-rem showed a strong correlation with the maximum P adsorption capacity, adsorption energy, and the amorphous and crystalline forms of Fe. The minerals of aluminum contributed the most to P fixation. P-rem was the best estimator of PBC. The soils with high, moderate and low rates of P fixation showed high amounts of the fractions P-Al, P-Ca, and P-Fe, respectively. The results showed that P fixation was influenced by the fractions of P in the soil, suggesting that the efficiency of phosphate fertilizers in tropical soils depends on the mineralogy of the clay fraction within those soils.

The collapse of the Fundão tailings dam of the Samarco mining complex in Mariana, Brazil, was the largest mining disaster in the world to date with many socio-economic and environmental impacts. Soil affected by mining tailings was severely altered with negative impacts for agriculture. We tested whether diluting mining tailings with organic soil would eliminate or at least attenuate the ecotoxic effects on plant development and performance. We cultivated radish, Raphanus sativus, in substrates containing different proportions of mining tailings and organic soil: pure tailings (T100%); 2) tailings75% + soil25% (T75%); 3) tailings50% + soil50% (T50%); 4) tailings25% + soil75% (T25%), and 5) pure organic soil (Soil100%, control). There were large differences in soil quality parameters between the 100% tailings treatment (T100%) and the control (Soil100%), as well as for some parameters in the most diluted treatment - T25% (Ca2+, Fe, Mn) in relation to the control treatment. Although dilution of the tailings soil improved radish development, there was lower radish productivity (leaf area, total biomass, and root/tuber biomass) than for pure soil (control). There were also significantly higher amounts of bioaccumulated metals in radish tubers grown with tailings, even when grown in T25% for Fe content and in T75% for Mn content. These results present a worrisome scenario for human communities in the region of the Doce river, as human consumption of crops produced in soil contaminated with tailings is not recommended due to potential toxicological effects from high metal concentrations.

The introduction of the African snail Lissachatina fulica worldwide poses a risk to the environment, agriculture and human health. Considered a socio-environmental pest it causes problems to plantations and gardens, in addition to threatening native species. Also, it can be an intermediate host of worms that affect humans and mammals. This work aims to evaluate the socioenvironmental impact caused by L. fulica in Alto Paraíso de Goiás, Goiás, Brazil. Specifically, it aimed to analyze the residents' knowledge about L. fulica, if they were able to recognize the invasive snail and differentiate it from the giant native snail Megalobulimus sp., in addition to the community's ability to carry out actions to combat the invasive species. Semi-structured interviews were conducted, guided by a questionnaire, with the urban population, and an unstructured interview with a health surveillance agent in the municipality. The area of the city was divided into five zones and ten residences were visited in each zone. It was found that the residents most affected by L. fulica are those who live in the most urbanized region of the city, with 86% of respondents reporting seeing the animal in the city center. The presence of the Megalobulimus sp. was reported by four residents in the city's border regions with the native Cerrado. Most of the reports of the African snail in the houses occurred by residents of Alto Paraíso de Goiás who had plants in their backyard and personally took care of them.

Published: June 2022

Currently, the fumes and dust generated from metal cutting and welding are not often treated well in many factories. This paper presents the results of designing, manufacturing the welding fumes filter system by applying electrostatic precipitator methods as well as studying the factors affecting performance of filters. There are many factors that affect the efficiency of electrostatic precipitator filtration, in this study, the welding fumes filter was experimented with parameters of gas flow velocity, filter pipe diameter and power capacity to find out the appropriate parameters. The outlet air quality was measured with a dust concentration gauge and the Box-Behnken method was used to determine the relationship among experimental parameters. The filter parameters are optimized to achieve 99% of filtration efficiency. The research results will be applied in practice to ensure the health of users and improve the surrounding environment as well.

Introduction:

Oligometastatic represents a distinctive subset of metastatic breast cancer (MBC). Incidence has been reported, in 1–5% of all newly diagnosed MBC. Literature is very sparse, especially from India.

Material and Methods:

We have ambispectively screened 500 patients of upfront female MBC between the period of January 2013 and August 2018 at Institute Rotary Cancer Hospital, All India Institute of Medical Sciences, New Delhi and 120 patients of oligometastatic breast cancer (OMBC) were included for analysis. Clinical, pathological, receptor status (ER estrogen receptor, PR progesterone receptor, and HER2/neu human epidermal growth factor), radiological, treatment, and survival details were recorded.

Results:

The median age of presentation was 50 (range 22–78) years. One organ was involved in 96 (80%) patients, and two organs were involved in 36 (20%) patients. ER and/or PR was positive in 48 (40.0%), ER/PR, and HER2/neu were positive in 28 (23.3%) cases. Only HER2/neu was positive in 21 (17.5%), and triple negativity was seen in 23 (19.2%) patients. Ninety-four (78.3%) patients received neoadjuvant therapy, and 12 (10%) patients underwent conservative breast surgery. The overall response rate at the metastatic site was 74.1%, and a complete response was seen in 42.5% of patients. Median progression-free survival (PFS) for the cohort was 25.43 months. The estimated PFS at 2 years and, at 5 years, was 54.6% and 21.6%, respectively. The hormone receptor positivity, bone metastasis, and patients with surgery after neoadjuvant chemotherapy (NACT) had a statistically significant better PFS on multivariate analysis. In a subset analysis of HER2/neu receptor-positive patients, who received targeted therapy showed better PFS compared to those who did not receive.

Conclusion:

The incidence of OMBC is 24% of the total MBC. The patients with OMBC who have hormone receptor-positive, bone-only metastasis, and surgery after NACT show a better outcome.

Primary epithelial-myoepithelial carcinoma (EMC) is a rare low-grade malignant neoplasm of the lung that originates from the submucosal bronchial glands. It behaves in an indolent fashion, although rare cases with high-grade transformation have been reported. Because of the rarity, optimal therapy for this entity has not been clearly defined. Herein, we report a case of primary pulmonary EMC in a 38-year-old Indian man who had a short history of dyspnea and a computed tomographic (CT) scan revealed a 3 cm diameter homogeneous mass in the lower lobe of the right lung. A CT-guided biopsy revealed a mildly atypical and mitotically quiescent tumor with solid and focal acinar arrangement; foci with biphasic arrangement by inner epithelial and outer myoepithelial cells were identified. The neoplasm revealed cytokeratin (CK) 7 positivity in the epithelial cells, while the myoepithelium expressed smooth muscle actin and p63. The tumor had a low (8%) Ki-67 proliferation index. The neuroendocrine markers, thyroid transcription factor 1, CK5/6, p40, and napsin A were negative. Positron emission tomography-CT was negative for any other mass lesion. The mass was excised with negative margins and the patient was on close follow without any evidence of disease for the past 17 months. A custom made, targeted DNA- and RNA-based 5 gene lung cancer next-generation sequencing panel (Epidermal growth factor receptor (EGFR), anaplastic lymphoma kinase (ALK), Ros protocol-oncogene 1 tyrosine kinase (ROS1), B-rapidly accelerated fibrosarcoma family oncogene (BRAF), and mesenchymal epithelial transition molecule (MET)), compatible with the Ion S5 system was performed; however, no mutation was identified. This case depicts awareness about this entity and use of appropriate immunostains, particularly the myoepithelial markers are essential to arrive at a correct diagnosis. Importantly, high-grade transformation, recurrence, and metastases are not very uncommon in EMC, warranting a correct and timely diagnosis for therapeutic decision-making and prognostication of the patient.

Published: June 2022

Background and Objective:

Most patients with oral cancer receive chemoradiotherapy with or without surgery for treatment and develop oral mucositis, a debilitating adverse. Currently, there is no standard regimen for the management of radiation-induced mucositis. This study aims to evaluate the effect of honey on radiation-induced mucositis.

Methods:

The study consisted of 204 subjects of both genders, diagnosed and treated by radiotherapy for head and neck carcinoma and who had developed oral mucositis. The control group (n = 102) received 0.9% normal saline while the interventional group (n = 102) received honey as a topical application. Both groups were evaluated by the World Health Organization oral mucositis assessment scale at baseline (I visit) and four follow-up visits.

Results:

A decrease in the progression of the lesion and symptomatic relief were found in the interventional group. There was neither symptomatic relief nor a decrease in mucositis grade in the control group.

Conclusion:

Within the limits of this study, the results showed that the topical application of honey could be used to alleviate the symptoms in the management of radiation mucositis as it is easily available, simple, and economical.

Authors: Jayanthiswari K. , Manoharan G.V. Murali Gopika , Muthukumar S.
Published: June 2022

Introduction:

Oral submucous fibrosis is a chronic, premalignant condition of the oral mucosa, affecting millions of people globally and it is one of the precancerous conditions most prevalent in India. Previously published studies have evaluated the serum lipid profile and C-reactive protein in various potentially malignant disorders and oral squamous cell carcinoma, but to our knowledge, no studies are available comparing the pre- and post-treatment serum lipid profile and C-reactive protein values in oral potentially malignant disorders, so that their real prognostic value can be assessed.

Aim:

The present study aims to evaluate the serum lipid profile and C-reactive protein as a prognostic marker in Oral Submucous Fibrosis patients.

Materials and Methods:

A total of 30 clinically diagnosed OSF patients of either gender in the age group of 20 – 50 years were selected. A complete history taking followed by a thorough oral examination was done on all patients. About 5 mL of blood sample was collected before treatment and after 6 weeks of treatment for estimation of serum lipid profile and C-reactive protein

Results:

The mean values of serum lipid profile were decreased among OSF patients and the difference between pre- and post-treatment was statistically significant. The comparison of the mean values of the pre- and post-treatment CRP level of the study subjects among OSF patients was found to be statistically significant (P = 0.022).

Conclusion:

Hence, pre- and post-treatment serum lipid profile and CRP levels contribute to being of prognostic value in OSF.
