Published: December 2023

Midbrain abscess is an uncommon pathology, especially in paediatric patients. Establishing a guideline for managing brain-stem abscesses is not yet well described, as few paediatrics patients have been treated for this central nervous system infection type. A 3-year-old boy was admitted for facial paralysis. A brain magnetic resonance imaging showed a brain-stem abscess. He was put on Teicoplanin and cephalosporin third generation for four weeks, with favourable evolution. The prognosis in paediatric brain-stem abscesses is generally favourable. Most patients recover with minor neurologic deficits or improve ultimately.
A rare case of Klippel–Trenaunay syndrome in a neonate
Authors: Surandran Sukrutha
Published: December 2023

Klippel–Trenaunay syndrome (KTS) is a rare syndrome of congenital capillary-venous vascular malformation associated with altered limb bulk and/or length. It is characterised by capillary nevus, varicosities and hypertrophy of bones and tissues of the affected limb. These three features constitute the primary diagnostic criteria of this syndrome. Although the cause of this disorder is unknown, it has a sporadic occurrence with some reports mentioning autosomal dominant transmission as well. The diagnosis of this embryological malformation is mainly clinical along with supportive evidence from other imaging modalities. In this article, we report a 5-dayold male baby who had phenotypic features suggestive of KTS and was later confirmed by magnetic resonance imaging.

In recent era, development of nanotechnology is an art of delivery of drug by improving its compatibility, effectiveness and efficacy. Among all nanoparticles, magnetic nanoparticles play a predominant role to shows their targeted drug delivery using a magnetic field, also helps to diagnose the diseases like cancer. The present study included preparation of four different mesoporous nanoparticles using the Pluronic block copolymer P123 as a surfactant template, then insert iron oxides using co-precipitation method. The resulted formed mesoporous magnetic nanoparticles are examined for structural characters by using FTIR, XRD, HRSEM and Elemental Mapping techniques. The results of X-ray diffraction (XRD) showed that the formed composites conserved ordered mesoporous structure after the formation of iron oxide nanoparticles in the pores. FTIR results indicated that the surface contains silanol group and Fe–O on the surface of the materials at 1060 cm-1 and 1020 cm-1 peaks respectively. Scanning electron microscopy (SEM) results showed that all mesoporous magnetic nanoparticles within the range of size from 50 to 100nm also possessed a regular spherical shape. These particles possessed high surface area, high pore volume and showed magnetic response sufficient for drug targeting in the presence of an external magnetic field. Elemental mapping data indicated about the percentage of all elements present in the mesoporous materials. We concluded that all four types of magnetic nanoparticles are structurally arranged in their structure with sufficient percentage of elements on their particle surface along with good size range. Further loading of drug into all types of magnetic nanoparticles decides the loading efficiency, stability and drug release nature.

Authors: Rao Chandana Narasimha , Sujatha M.
Published: December 2023

The heavy metals such as chromium (Cr), lead (Pb) and cadmium (Cd) are considered as serious toxicants and act as carcinogenic agents that cause serious cancers to humans. The use of these heavy metals drastically increased in various industrial applications and subsequently increased the risk of contamination of these heavy metals in soil, water etc. To minimize the negative effects of these heavy metals, there is a need to reduce these heavy metals concentrations in environment samples. Hence this study focused to fabricate iron nanoparticles using Diospyros chloroxylon (Roxb.) for the removal of carcinogenic metals in water. The crystal structure, size and morphology of the nanoaprticles were evaluated and it was found that the particles were of rod shape with smooth surface and rhombohedral phase structure with an average particle size of 24 nm that contains 71.91 % of elemental iron. The heavy metal sorption experiments was conducted using selected concentration of heavy metal solution at various pH ranges, time and agitation rate. The maximum adsorption removal was 95.36 %, 98.42 % and 92.80 % within 120 min equilibrium time for Cr, Pb and Cd respectively suggesting that the nanoparticles possess high adsorption efficiency. The adsorption process follows pseudo-first order reaction kinetics with correlation coefficient of 0.978, 0.994 and 0.994 with rate constant (K) of 0.140, 0.280 and 0.108 respectively for Cr, Pb and Cd. The results suggest that the synthesized iron nanoparticles were biocompatible, stable and reusable that can be effectively utilized as promising agents for the removal of carcinogenic heavy metals in polluted water.

Published: December 2023

Urea is widely used in agriculture and aquaculture as a major source of nitrogenous fertilizer. Therefore, urea exists in dissolved form in the marine/freshwater ecosystem. However, if the concentration in waterbodies is higher than a threshold limit, it can be toxic to fish and prawns. Therefore, accurate measurement of urea is a must even in marine water systems. Estimation of urea from freshwater samples using colorimetric method is well established. The well-known diacetyl monoxime method is widely used for accurate estimation of urea from fresh water as well as various biological samples. The presence of various interfering ions in sea water affects the estimation and limits the adaptability of any new methods directly into sea water. The accurate and precise estimation of urea are essential to optimize the nutrient addition. In this study, the diacetyl monoxime method was considered for urea estimation in sea water (3.5% salinity) and the method was validated for specificity, linearity, robustness, ruggedness and sensitivity as per International Council for Harmonization guidelines. During this study, urea showed maximum absorbance at 524 nm wavelength in both the samples. This method was found linear up to 100 ppm of urea in fresh and sea water samples. The variations of wavelength by 5-10%, reagent volumes by 2.5-5%, sample storage, analysis did not show any significant impact on the estimation of urea from both the samples. However, the method was found more sensitive and showed the limit of detection of 0.5 ppm in fresh water and 1.5 ppm in sea water. The overall results indicate that this method is accurate and robust for sea water samples and therefore can be used for estimation of urea in sea water samples.

Authors: Varshney K. Pradeep , Malhotra Shveta
Published: December 2023

The use of lithium-ion batteries (LIBs) is on stimulating expansion and is expected to increase remarkably. The primary and secondary LIBs have been extensively used in electronic industries and are surging high in hybrid electric vehicles. The considerable use of LIBs could lead to the high accumulation of lithium and lead to the dissipation of the natural lithium reserves. The waste LIBs contain toxic chemicals and heavy metals that are hazardous to the environment. Thus, tremendous research work is being carried out for recycling spent LIBs. This will minimise the pollution from inappropriate disposal of Li in e-waste and would aim towards sustainable development. This review introduces the structure of LIBs and different composition of cathode material used in LIBs. It further discusses the various technologies including pre-treatment processes, pyrometallurgy and hydrometallurgy involved in recovering Li from waste LIBs. Additionally, challenges and suggestions for improving current recycling process have been presented.

Published: December 2023

Netflix, 2016 yılında Türkiye pazarına girmiştir. Netflix Orijinal Türkiye ise 2019 yılında ilk yerli dizi olan Hakan: Muhafız dizisi ile yerli yapım dizileri ve 2020 yılında yerli yapım filmleri yayınlamaya başlamıştır. Dizi süreleri ve izleme alışkanlıklarına yenilikler getirdiği bilinen Netflix, bünyesinde bulunan yerli yapım filmlerinde yerleşik melodram kalıplarından (iyi-kötü zıtlığı, fakir ama mutlu, zengin ama mutsuz karakterlerin karşıtlığı, duygusal aşırılıklar ve olayların gelişmesinde neden-sonuç eksikliği gibi) yararlanmaktadır. Biçimsel yenilikler, Netflix’in kullandığı film dilinde görülmemektedir Filmler, sıklıkla ana-akım sinemanın cesur ve kamusal alana ait erkek, fedakâr ve özel alana ait kadın gibi kodlarını ve türsel özelliklerini kullanmaktadır. Erkek kahramanın ödipal yörüngesini seyircilere sunan filmlerde kadın karakterler ise genelde bir gizem unsuru ya da erkek kahramanın amacına ulaşması için nesne olarak görülmektedir. Bu durum, toplumsal cinsiyet rollerinin ve kalıp yargılarının yeniden üretilmesini sağlarken erkeğin gücünü sağlamlaştırmaktadır.
Çalışmada dijital yayıncılık ve Netflix, melodram türü ve Türk sinemasında melodram ve feminist film kuramında ödipal yörünge başlıkları incelenecektir. Çalışmada ele alınan Beni Çok Sev (Mehmet Ada Öztekin, 2021), Babamın Kemanı (Andaç Haznedaroğlu, 2022) ve Cici (Berkun Oya, 2022) filmleri, melodram türünün uylaşımlarına sahiptir ve erkek kahramanın ödipal yörüngesini izlemektedir. Melodram ve ödipal yörünge temalarında ele alınacak bu filmlerin klasik anlatı geleneğinden ve Yeşilçam melodramlarından sıyrılıp sıyrılmadığı incelenecektir.
Devi postfacière de Tchak : les origines d’un malaise littéraire
Authors: De Meyer Bernard
Published: December 2023

Complice littéraire de Sami Tchak depuis une bonne quinzaine d’années, Ananda Devi a rédigé une postface à l’ouvrage Les fables du moineau de l’auteur togolais, paru au Seuil en 2020. Ce court texte se situe dans la suite de résonances entre l’œuvre du Togolais et de la Mauricienne, et est présagé en particulier dans les nouvelles que les deux écrivains ont insérées dans l’ouvrage collectif Paris, lumières étrangères, publié deux ans plus tôt (2018). Cet article part de la notion de postface, telle que définie par Gérard Genette, pour ensuite faire une analyse de ce récit qui met en valeur le conflit intérieur qui existe chez Devi : encouragée par Tchak de vivre la vie de ses personnages, elle se met en scène dans cette histoire fictive et subit une expérience mystique à l’issue fatale. Ces événements sont situés durant une nuit à Naples pendant une éruption volcanique. Des parallélismes, aussi bien formels qu’au niveau du contenu, seront établis avec la nouvelle « Octavie » de Gérard de Nerval, dans laquelle le héros (Nerval lui-même) éprouve les mêmes sensations dans la capitale campanienne. Au centre de mes préoccupations se trouve la volonté d’Ananda Devi de se défaire d’une forme d’écriture, presque stéréotypée, qui la distingue et qui continue de la hanter.

Authors: Tajeyan Silvia
Published: December 2023

La investigación se centra en el análisis de diferentes problemas presentados en el libro del Álgebra de Mohhamed Ben Musa y de las posibles raíces en los problemas que presenta el Corán y el proceso de construcción del concepto matemático, dado desde el entorno y por quiénes lo crearon para favorecer el aprendizaje y una reflexión en la práctica docente para contribuir en ese aprendizaje mediante su construcción en el aula. Este tipo de análisis se basa en la construcción social del conocimiento y sus cuatro componentes: epistemológica, cognitiva, didáctica y social. Puesto que la socioepistemología afirma “que el conocimiento matemático es una construcción sociocultural en cuyo surgimiento y desarrollo se lleva a cabo en el seno de una sociedad y refleja las características de ésta” (CRESPO CRESPO, 2007, p. 3). Puesto que el álgebra es un tema importante desde la escuela media, se intenta identificar las características propias del pensamiento algebraico con el fin de lograr el proceso de aprendizaje de los alumnos y así darle el sentido y el significado a cada uno de los conceptos del álgebra. Con un análisis inicial en la historia de la matemática y las características que generaron estos problemas y sus soluciones, y no sólo las del tipo algorítmico puesto que los árabes cuentan con demostraciones geométricas, en ecuaciones de segundo grado que pueden dar sentido en el aula al resolverlas de esta manera, ser resueltas.
Factors Determining the Behavior of E-commerce Users According to the Demographic Aspects of College Students
Authors: Da Silva Brenda Corrêa , Nascimento-e-Silva Daniel
Published: December 2023

Purpose: E-commerce is a supply of needs typical of the information age. Based on contemporary technologies, it has represented an up-and-coming channel for multiplying the possibilities of supplying demands practically everywhere on the planet. So that it can be constantly improved, scientists and managers have been concerned with better understanding the behavior of online buyers. In this sense, this study aimed to identify the determining factors of e-commerce according to demographic aspects (purchase frequency, income, paid activity, age, and gender) of university students at an institution in the North of Brazil.

 

Theoretical framework: The study was theoretically based on the factors and variables determining consumer purchasing behavior. Factors as analytical dimensions formed a theoretical architecture, each composed of their respective variables and analysis categories.

 

Design/Methodology/Approach: The method used was a survey, whose population consisted of 51 students enrolled in the second semester of 2022, from which a sample of 47 respondents was extracted, given that the others dropped out of class. Data were collected with a questionnaire with closed questions, the validity of which was checked with a Cronbach's alpha test at 0.82, considered very compliant. The results were generated using the Mann-Whitney U test, given that the behavior of the variables was not regarded as normal by the Kolmogorov-Smirnov and Shapiro-Wilkens tests. The conclusion points to a kind of virtual democracy in which little differentiation can be seen in the factors determining purchases when taken from the point of view of the demographic variables studied.

 

Findings: The results showed no differences in the determining factors of e-commerce regarding paid activity, frequency of purchases, and age. A difference in behavior was detected between men and women regarding price and between those with higher incomes and those with lower incomes regarding practicality.

 

Research, Practical, and Social Implications: The practical implication of the study is that marketing strategies and new product launches offered in the virtual world can be mainly standardized because the demographic differences that impact the behavior of virtual consumers are statistically similar. From a theoretical point of view, the results indicate the need to study other demographic variables to confirm or refute these behavioral uniformities.

 

Originality/Value: The contribution of this study to the science and practice of electronic commerce is the finding that consumers present similar behaviors when considering the demographic aspects of university students, who represent a large portion of virtual buyers.

La investigación trata acerca del detalle de manifestaciones clínicas después de una extravasación de hipoclorito de sodio, por ser la solución irrigante más usadas en el mundo. El accidente con hipoclorito de sodio es una de las complicaciones que pueden presentarse durante la terapia endodontica convencional. Sucede en el sobrepaso del irrigante a los tejidos periapicales ya sea durante la irrigación de los conductos radiculares o por medio de la inyección accidental en los tejidos blandos. Al suscitarse una complicación el paciente muestra una sintomatología dolorosa inmediata, con una respuesta inmunológica exacerbada y necrosis. El objetivo del presente es mostrar el protocolo de manejo clínico y farmacológico establecido para esta complicación para ello serán localizados en la literatura científica disponible en base de datos como pubmed, scopus y scielo. Si bien la extravasación de soluciones irrigantes es poco reportada en la literatura, este accidente puede ocurrir debido a que la anatomía del forámen apical es muy amplia o incluso por negligencia al inyectar la solución irrigante dentro del canal durante el proceso de desinfección de los conductos El tratamiento de este incidente varía dependiendo de la gravedad del incidente, que se divide en lesiones leves, moderadas y graves que deben ser muy bien identificadas por el profesional.

Published: December 2023

La fibrilación auricular (FA) es una arritmia cardíaca compleja, multifactorial, que con frecuencia se relaciona con el proceso de envejecimiento. Es la arritmia sostenida más común en la práctica clínica. Es asintomática en la mayoría de los pacientes, pero es la causa más frecuente de embolia cerebral en las personas mayores y se asocia con una mayor tasa de hospitalizaciones y mortalidad. La presente investigación se enmarca dentro de una metodología de tipo bibliográfica documental. Ya que es un proceso sistematizado de recolección, selección, evaluación y análisis de la información, que se ha obtenido mediante medios electrónicos en diferentes repositorios y buscadores tales como Google Académico, Science Direct, Pubmed, entre otros, empleando para ellos los diferentes operadores booleanos y que servirán de fuente documental, para el tema antes planteado. La fibrilación articular es una patología frecuente en los ancianos, que conlleva a riesgos elevados de deterioro clínico y funcional de accidente cerebrovascular (ACV). Las estrategias de tratamiento y/o manejo son variadas, pero se parte de dos métodos o premisas fundamentales que son el control del ritmo y el control de la frecuencia, sin embargo, todo ello va a depender de la clínica y las comorbilidades que presente o no el paciente, que quiere decir esto, si el paciente presenta ya una enfermedad cardiovascular o no, ya que ciertos fármacos pueden generar complicaciones, es por ello que cada caso debe ser manejado de forma individual.
VOCATION AND CAREER CHOICE IN HIGHER ART EDUCATION
Authors: Oleksiuk Olha
Published: December 2023

Music education in the early 21st century is aimed at a new educational paradigm in the context of post-non-classical art pedagogy. An integral feature of modern art education is focus on formation of an artist with a bright, multifaceted and creative individuality, as well as vocation for potential career choice. It means an individual’s awareness of the conditions and requirements of social existence, the readiness and ability to respond to social changes and needs, to hear and understand one’s personal calling in them. Vocation is an ethical phenomenon, a manifestation of motivation to achieve intangible benefits or do good. At the same time, vocation is an existential phenomenon. A person lives in a vocation, seeks it for himself, feels the futility of existence without it. In general, in applied research, vocation is associated with a certain human activity, mainly professional. Thus, pedagogical activity is combined with a professional vocation. These processes take place through the assimilation of the experience of previous generations and contemporaries, where the individual is involved in the cultural and spiritual space of his community. The sense of art education is to focus a person’s attention on the purpose of his creative activity, on understanding and choosing the good that he wants to grasp and realize in his life. Therefore, it is relevant to discuss the possibilities of practical implementation of the vocation factor in the system of music education and specialists training in this field. This provides an opportunity to form a new type of mentality and behavior of people, in which the motive of the individual’s self-development plays a more significant role.
Anisian (Middle Triassic) ammonoids from North America: quantitative biochronology and biodiversity
Authors: Monnet Claude , Bucher Hugo
Published: December 2023

This study synthesizes and revises the ammonoid zonations as well as their correlationwith each other for westernNevada (USA), British Columbia (Canada), and the Sverdrup Basin (Canada) by utilizing the unitary association method. Based on a standardized taxonomy, the Anisian in the studied areas contains 13, 10, and 3 zones and a total of 174, 90, and 7 species, respectively. The zonations are correlated bymeans of a ‘common taxa zonation’, which includes all taxa common to the studied basins. This leads to new andmore precise correlations,which are at slight variancewith those of the literature.Hence, the Buddhaites hagei Zone (Canada) correlates only with the Intornites mctaggarti Subzone (Nevada) and not with the entire Acrochordiceras hyatti Zone (Nevada). The Tetsaoceras hayesi Zone (Canada) appears to correlate with the Unionvillites hadleyi Subzone (Nevada) of the hyatti Zone and not with the Nevadisculites taylori Zone. The Hollandites minor Zone (Canada) more than likely correlates with the taylori Zone (Nevada) rather than the Balatonites shoshonensis Zone as is usually acknowledged. The unitary association method enables us to quantify the diachronism of the studied taxa,which affects about 67% of the genera and 18% of the species common toNevada and British Columbia. Therefore, this diachronism is significant and its value for correlation should not be overlooked. Finally, a diversity analysis based on the revised zonations is performed. This analysis reveals that the major event occurred during the Nevada hadleyi Subzone (early Middle Anisian), which in Nevada and British Columbia, records the highest species richness of the Anisian as well as enhanced exchanges between usually latitudinally restricted faunas. This event may reflect significant changes in climate or oceanic circulation at that time.
Geochemistry and mineralogy of the Paleocene/Eocene boundary at Gabal Dababiya (GSSP) and Gabal Owaina sections, Nile Valley, Egypt

Published: December 2023

This work deals with the geochemical and mineralogical characteristics of the period representing the Paleocene-Eocene Thermal Maximum (PETM) succession, at both the Gabal Dababiya Paleocene-Eocene GSSP and the Gabal Owaina sections. At both sections, the sediments deposited during this interval contain varied amounts of phosphatized and silicified fish debris, pyrite framboids, pseudomorphs of hematite spherules, calcite and detrital minerals. At Gabal Dababiya, the PETM succession is characterized by strong anomalies inmost chalcophiles, especially in the lower part of the clay bed, aswell as in the coprolite-rich and the bone-bearing strata. In contrast, such concentrations of the chalcophile elements have not been recorded at G. Owaina. This leads to the conclusion that these trace elements are incorporated in the phosphatic components (fish debris and coprolites) and in the clay-fraction and/or organic matter. The association of SiO2*-excess, and P2O5 enrichment with an abundant radiolarian fauna and enrichment of the organic matter within the first three beds of Dababiya Quarry Beds, indicates high productivity and upwelling throughout their deposition. In the course of the upwelling activity,water rich in nutrients rose to the surface, enriching sediments with organic matter. The increased consumption of oxygen caused by the sinking of organic carbon to the bottom resulted in a redox front at or just above the sediment-water interface. At G. Owaina, the internal molds of radiolarians, as well as benthic and planktonic foraminifera which are represented by hematite spherules, are abundant in the post-PETM succession. This is an indication that silica and calcite dissolution, rather than low productivity accounts for the absence of opaline silica and biogenic calcite. Solutions resulting from the dissolution of siliceous and calcareous oozes may have penetrated lower layers and formed Ca-Si-rich components (silicified fish debris and Ca-Si-rich phase).
