Published: December 2021

Свойства межфазной поверхности магнитной жидкости на границе с водой в электрическом поле изучались во многих работах. Были обнаружено изменение отражательной способности межфазной поверхности вода – магнитная жидкость в электрическом поле, что авторами связывается с образованием на межфазной границе слоя плотноупакованных частиц. По оптическим и электрическим измерениям оценена толщина d этого слоя. Интерес к этим эффектам, помимо чисто академического, связан с возможностью управления поведением межфазной границы раздела магнитного коллоида и гомогенной жидкости внешним электрическим полем, что представляет практический интерес, поскольку слой частиц магнетита на межфазной поверхности может быть интерпретирован как жидкая мембрана с особыми свойствами. Задача настоящего исследования – теоретически показать, что образование слоя частиц дисперсной фазы магнитной жидкости в электрическом поле и связанное с этим уменьшение межфазного натяжения является определяющим фактором для развития волновой неустойчивости.
A layer of close-packed particles of a dispersed phase (magnetite) with a protective shell of oleic acid is formed on the interface of a weakly conducting magnetic colloid (magnetic fluid) and water in a perpendicular electric field. The formation of a layer leads to a decrease in the interfacial tension. When the magnetic particles come into contact with the electrode surface, the electrochemical interaction of oleic acid molecules surrounding the particle with water occurs. As a result of the reaction, released ions charge the surface layer. After some time, the particles in the layer get recharged and repelled from the interface. This leads to wave instability. This paper considers the mathematical modeling of instability in the form of a boundary value problem – a dispersion equation. The determining factor in the development of wave instability is the action of the electric field, the formation of the near-electrode layer and, as a consequence, a decrease in the interfacial tension.

Lagoon ecosystems: peculiarities of the species, spatial and trophic structure of macrobenthos (Kandalaksha bay, White sea)
Authors: Столяров Андрей Павлович 
Published: December 2021

Изучены видовое разнообразие, пространственная и трофическая структура макробентосных сообществ сублиторали и нижних горизонтов литорали в 5-ти лагунных экосистемах Кандалакшского залива Белого моря. Всего в исследованных экосистемах было обнаружено 52 вида бентосных беспозвоночных животных и 6 видов морских трав и водорослей. В сублиторали наибольшим видовым разнообразием, общей плотностью и биомассой макробентоса характеризуется наиболее открытая к морю лагуна, расположенная на выходе из кутовой области Кислой губы, а наименьшим - наиболее закрытая и заиленная лагуна Никольской губы, где преобладали солоноватоводные и морские эвригалинные виды. Промежуточное положение занимали лагуна Ермолинской губы, лагуна, расположенная рядом с Ершовским озером и лагуна на Зеленом мысу. В нижней литорали общие показатели структуры сообщества макробентоса (общая плотность, биомасса и в меньшей степени видовое разнообразие) в отличие от сублиторали увеличивались от менее зарегулированных и открытых экосистем к более закрытым системам. Исключением является лагуна Никольской губы, значительное заиление которой приводит к существенному уменьшению видового разнообразия и снижению общей плотности и биомассы сообщества макробентоса.
The species diversity, spatial and trophic structure of macrobenthos communities in the sublittoral and lower littoral horizons in five lagoon ecosystems of the Kandalaksha Bay of the White Sea have been studied. In total, 52 species of benthic invertebrates and 6 species of sea grasses and algae were found in the studied ecosystems. In the sublittoral zone, the highest species diversity, total density and biomass of macrobenthos is characterized by the lagoon most open to the sea, located at the exit from the innermost area of Kislaya Bay. The lowest diversity is found in the most closed and silted lagoon of Nikolskaya Bay, where brackish water and marine euryhaline species predominated. The lagoon of the Ermolinskaya Bay, the lagoon located next to the Ershov Lake and the lagoon on Cape Verde hold an intermediate position. In the lower littoral zone, the general indicators of the structure of the macrobenthos community (total density, biomass, and, to a lesser extent, species diversity), in contrast to the sublittoral one, increased from less regulated and open ecosystems to more closed systems. An exception is the lagoon of Nikolskaya Bay, the significant siltation of which leads to a significant decrease in species diversity and a decrease in the total density and biomass of the macrobenthos community.

“This is a Business Transaction, Fundamentally”: Surrogate Motherhood in Meera Syal’s The House of Hidden Mothers
Authors: Pérez Fernández Irene 
Published: December 2021

Meera Syal’s latest novel, The House of Hidden Mothers (2015), depicts the current practice of international surrogacy and raises questions about this form of reproduction which commodifies babies and constructs poor women’s bodies in India and elsewhere as sites of reproductive exploitation. Nonetheless, Syal’s novel challenges an initial reading of Indian surrogate mothers as mere passive victims of western capitalist demands and depicts a surrogate mother, Mala, who constantly subverts her position as a disempowered, ‘third world’ woman. I shall argue that the novel bridges the discursive western-constructed gap between ‘poor and disempowered’ Indian women and ‘rich and empowered’ British ones explicitly through its ending, but also implicitly by engaging with gender concerns related to the perception, (re)presentation and exploitation of women’s bodies in the United Kingdom and India alike.
Forms of Capital in F. Scott Fitzgerald’s “Winter Dreams”
Authors: Akhavi Zadegan Raheleh , Pirnajmuddin Hossein 
Published: December 2021

This paper offers a reading of F. Scott Fitzgerald’s “Winter Dreams” (1922) in the light of Pierre Bourdieu’s theorization of forms of capital. Fitzgerald’s story is centrally concerned with social class and addresses the rise of consumer culture in the 1920s. It is about a Midwest American trying to improve his economic and social status to win the hand of a wealthy girl he loves. At issue here are different types of capital (economic, social, cultural, symbolic), hence the relevance of Bourdieu. Thus, we explore in Fitzgerald’s story the way characters are engaged in everyday practices as social agents competing with other social agents to accumulate ‘capital’. In the process of socialization, the economic capital provides the protagonist with luxury but the lack or shortage of other forms of capital —especially cultural capital— cause him to fail in the pursuit of his heart’s desire.
Lo plausible: similitudes y diferencias entre la Malinche y Pocahontas
Authors: Fernández Santiago Míriam 
Published: December 2021

Los mitos desarrollados a lo largo de varios siglos a partir de los personajes históricos de la Malinche y Pocahontas han tenido en ciertos aspectos un desarrollo dispar, que es un reflejo de las políticas coloniales de los imperios español y británico, así como de las diferentes posturas postcoloniales que surgen en los
Estados Unidos y en México tras su independencia. Este artículo analiza las similitudes existentes entre estos dos personajes históricos y trata de explicar la divergencia que se produce en el desarrollo de sucesivas narrativas tanto “históricas” como ficticias de las que son el eje central. De dicho análisis se concluye que los
extremos norte y sur de la frontera norteamericana elaboran un discurso diferente a partir de realidades históricas plausibles en cuya base se encuentran las señas de identidad de las naciones mexicana y estadounidense.

This study aims to determine the inhibiting factors for early reading in grade II students of SDN 32 Cakranegara and alternative solutions that can be used so that they do not experience obstacles in beginning reading. Internal factors include intelligence, interests, talents, and motivation, while external factors include family environment, school environment, and community environment. This type of research uses a descriptive qualitative approach. Data collection techniques were carried out through interviews, observation, and documentation. The data analysis technique used is data reduction, data presentation, conclusion or verification. . Test the validity of the data using triangulation of sources, and the availability of references. The subjects of this study were second grade students. The results of this study indicate that the inhibiting factor for early reading of students in grade II is the lack of interest, talent, motivation from within the students themselves to learn to read, this is also supported by family and school environmental factors. First, the lack of support and motivation from parents and families towards students in the absence of special attention given to students in teaching students to read at home, secondly, the absence of teacher creativity in teaching students to read and the absence of facilities from schools that support the learning process. There are also strategic efforts used by the teacher in overcoming the obstacles to students' early reading, namely dividing students / focusing on teaching students who cannot read, providing special books for early reading, playing games / games, reminding parents to often teach children to read at home, no matter how busy they are, and train students on a daily basis.
Keywords: analysis, inhibiting factors, early reading, SDN 32 Cakranegara.
Investigation of Two Precipitation Methods for Extracting Immunoglobulin Y (IgY) from Egg Yolks
Authors: Quynh Lan Tran Thi , Kha Tran Trong 
Published: December 2021

Two groups of hens (control and immunization group) were arranged in an experimental design with an immunization schedule of 3 injections of BSA antigen. IgY antibodies were extracted from egg yolks by two precipitation processes (chloroform and polyethylene glycol precipitates) and quantified using a standard curve of protein concentration. The purification of IgYwas confirmed by SDS-PAGE. Total protein extracted from egg yoks were less contaminated with yellow pigments (lutein and zeaxanthin) by using chloroform precipitate. The 2nd week post-immunization, IgY concentration increased respectively to 3903 ± 726 μg.ml-1 (chloroform extraction process) and 2937 ± 294 μg.ml-1 (PEG extraction process) (P < 0.01). After 3rdimmunization, IgY level obtaining from in immunization group extracted by chloroform process (6633 ± 1166 μg.ml-1) increased 2.7 times higher than that in control group (2482 ± 414 μg.ml-1). Whereas IgY concentrations obtained from PEG extraction process were not significantly different between the experimental group and control group. Chloroform and PEG precipitation methods had the same protein profile on the SDSPAGE. IgY antibody was identified by the presence of bands corresponding with IgY heavy chain (67-70 kDa) and IgY light chain (25 kDa) for both precipitation processes.
Satisfacción del universitario en su camino hacia la inserción socio-laboral: Un estudio de caso
Authors: Martínez-Clares Pilar , González-Lorente Cristina 
Published: December 2021

¿Está satisfecho el alumnado con el proceso de inserción socio-laboral iniciado en la universidad? La satisfacción de los estudiantes suele quedar en un segundo plano al analizar dicho momento de transición, tanto en la investigación como en los propios8 servicios de orientación profesional universitaria. Con el objetivo de medir este indicador de calidad en la educación superior, esta investigación pretende validar una escala de satisfacción ad-hoc basada en el triángulo formación-orientación-empleabilidad como marco teórico de la orientación en la educación superior. Se recurre al Análisis Factorial Confirmatorio y a la metodología SEM para la validación de la escala y se comprueba su fiabilidad mediante el estadístico Alfa de Cronbach. Los datos obtenidos con esta escala entre los 497 estudiantes de último curso participantes de la Universidad de New Haven (EE. UU.) y de la Universidad de Padua (Italia) se comparan a partir de la prueba no paramétrica U de Mann-Whitney. Los resultados demuestran la relevancia y adecuación de la escala de satisfacción con el proceso de inserción socio-laboral. Además, los estudiantes que completaron la escala en la UPD (Italia) están menos satisfechos que los participantes estadounidenses (UNH), lo que coincide con otros estudios relacionados. Se demuestra la adecuación de la escala de satisfacción como herramienta válida recopilar datos fiables para mejorar la orientación universitaria.
