Phylogenetic Analysis of Endemic Fish from the Maros Karst Region, South Sulawesi, Indonesia
Authors: Andy Omar Sharifuddin Bin
Published: February 2022

The Maros Karst is known for having a unique geomorphological structure with a diversity of endemic flora and fauna. The hydrology of this karst area is generally dominated by underground rivers with various freshwater ecosystems, which are generally dominated by endemic fish typical to Sulawesi. This study aims at identifying endemic fish of Maros Karst rivers using morphological and phylogenetic analysis as the baseline for further endemic fish conservation. Morphological analysis was done by comparing fish samples’ morphological characteristics with those from fish taxonomy references. Phylogenetic analysis was carried out using mitochondrial DNA (mtDNA) analysis with the target gene Cytochrome C oxidase 1 (CO1). The results showed there are five endemic fish species from four families and three orders from the Maros Karst area with a genetic distance value between 0.0 to 0.275. These species make particular adaptations both morphologically and genetically to the karst ecosystem. However, it is necessary to understand the evolution of these fishes to establish effective conservation measures. Therefore, it is necessary to have a management strategy to ensure the sustainability of endemic fish populations and as well as the sustainability of the karst ecosystem as a whole. © 2021 Friends Science Publishers

Authors: Hussain Zakir
Published: February 2022

This study aimed to determine the effect of betaine supplementation on production performance and blood biochemical parameters in calves. Sixty Nili-Ravi calves were randomly divided into four groups: the control group, which received a total mixed ration (TMR) without betaine and three experimental groups that received TMR blended with 0.2, 0.4 and 0.6% betaine for 8 weeks. Feed and water intake was recorded daily and production performance parameters were recorded on weekly basis. Blood samples were collected weekly and at the end of the experiment. The results showed that feeding betaine to calves increased dry matter intake, body weight gain and average daily gain (P < 0.001). Dietary addition of 0.6% betaine improved feed conversion ratio (P < 0.01). Plasma cortisol, superoxide dismutase, and malondialdehyde levels were positively affected (P < 0.05) by betaine supplementation as compared to the control group; however, it caused HSP70 levels to decrease (P < 0.05). The results indicated that supplementing betaine to the diet of Nili-Ravi calves enhanced growth performance and improved their antioxidant status. © 2021 Friends Science Publishers
Seagrass Debris as Source of Fiber and Bioactive Compounds in Feed for Dairy Goats
Authors: Hachana Yasser
Published: February 2022

Climate change has severely affected rainfall regularity, limiting grass growth and thus fodder availability. Finding unconventional resources has become a challenge for small and medium breeders to feed their livestock. The objective of this study is to determine whether the use of marine plant debris, Posidonia oceanica, as total or partial replacement of oat hay in alpine goat diets will affect or not milk yield and quality. The sea grass was characterized according to the sampling site. Chemical and phytochemical analysis revealed significantly higher levels of dry matter, minerals, total polyphenols and carotenoids in P. oceanica on banquettes than in floating Posidonia. The condensed tannin content was almost the same for both sites. Partial or total replacement of oat hay by P. oceanica in alpine goat rations significantly increased milk production and milk fat content, while somatic cell count decreased significantly. In addition, P. oceanica significantly enhanced milk biochemical composition by increasing flavonoid and total phenol contents. However, protein, lactose and freezing point parameters were not affected. Sensory analysis revealed substantial improvement in the organoleptic quality of P. oceanica fed goats’ milk compared to the other group, which was highly appreciated by most of the panelists. The seagrass P. ocanica could therefore be a safe solution to improve fodder availability for small and medium breeders, reduce production costs and increase milk market value. © 2021 Friends Science Publishers
Enhanced Growth and Drought Resistance in Seedlings of Acacia tortilis due to Inoculation of Arbuscular Mycorrhiza Fungi and Bacillus subtilis
Authors: Abdelmalik Abdelmalik M
Published: February 2022

A shade house experiment was conducted in Saudi Arabia to evaluate the impact of a mixture of three arbuscular mycorrhiza fungi (AMF) namely Funneliformis mosseae, Rhizophagus intraradices and Claroideoglomus etunicatum, a bacterium Bacillus subtilis, and their combinations on the growth and drought resistance potential of Acacia torilis seedlings under moderate and water deficit-stress. Thus, inoculants treatments (AMF, Bacillus subtilis, AMF+Bacillus, and control) and several watering intervals (1, 2, 3 and 4 weeks) were applied. Inoculation of AMF and Bacillus to A. tortilis seedlings found effective in terms of improved seedling growth. AMF and combined inoculation resulted in a larger shoot (shoot fresh and dry weights, seedling height, leaf number, leaf area) and root development (root fresh and dry weights, root length, root surface area, and root volume) as compared to the non-inoculated seedlings. Single inoculants of B. subtilis, showed better improvement in 1- and 2-week watering intervals compared to the control. Inoculated seedlings showed lower proline accumulation than non-inoculated seedlings, and thus improved seedling resistance to water deficit-stress. Mycorrhizal and mixed inoculation enhanced the amount of chlorophyll in the seedling’s leaves. Furthermore, seedlings with AMF and co-inoculants showed better drought tolerance even at 3- and 4-week watering intervals. © 2021 Friends Science Publishers

Authors: Pham Thi Thuy Nga , Tran Duc Hau , Nguyen Van Quyen
Published: February 2022

Mangrove forests provide important ecosystem services for nature and human beings, but these ecosystems have been threatened due to anthropogenic activities and climate change. The present study systematically presents ecosystem services based on literature review of published papers, and project reports. It reveals that ecosystem services from mangrove forests are diverse and different among localities. Amongst the three types of ecosystem services, the regulating is the most concerned (accounting for 40% of reviewed literatures), followed by the provisioning (accounting for 39%) and the cultural (accounting for 21%). There are more available data on ecosystem services from mangrove forests in the North and South of Vietnam than that in the Central (24 - 26 vs. 18%). Differences in studies on ecosystem services contribute to the lack of synchronicity in biodiversity conservation and sustainable development of this typical ecosystem in Viet Nam. Also, the present paper details three types of ecosystem services, compared levels of exploitation, and use of ecosystem services from mangroves in different regions. These results are scientific fundamentals for conservation, exploitation, and sustainable utilization of this ecosystem in the eco-social development. In addition, the present study introduces several options for further studies, exploitation of ecosystem services from mangroves in Vietnam, focusing on the connectivity, the stakeholder participation and remote sensing application.

Published: February 2022

The Khang Dan 18 is one of the rice cultivars widely cultivated in Vietnam, which is threatened by saline intrusion. This study is conducted to establish an in vitro culture system for evaluate salt tolerance of the rice cultivar Khang Dan 18. First, different culture conditions, including plant growth regulator concentration, culture period, light regime, were optimized to induce and maintain callus in vitro. Culture media supplemented with 10 - 40 µM 2,4- Dichlorophenoxyacetic acid (2,4-D) are suitable for inducing callus. Different culture periods (1, 2 and 4 weeks) significantly affected the callus morphology and nature. The 10-hour light photoperiod is the most effective condition for callus induction and multiplication. Callus cultured in the medium supplemented exclusively with 2,4-D showed higher quality compared to those in media supplemented with 1-Naphthylacetic acid (NAA) and 2,4-D. Different photoperiods also affected callus differentiation in terms of root\shoot induction. The established culture system was then employed to evaluate salt tolerance of the callus. The growth of callus was significantly decreased when the concentrations of NaCl increased (3, 6 and 9‰, P = 0.05), especially at the concentration of 9‰ NaCl caused a strong decrease in callus weight and an obvious change in callus morphology. This culture system may be applied for in vitro salt stress studies on the cultivar Khang Dan 18 and similar rice cultivars.

Published: February 2022

The HSP90 gene family has been shown to play an important role in the tolerance and development of plants. Papaya, which is a fruit crop with high nutritional value, is native to the tropics but now is widely cultivated in many subtropical regions of the world. Therefore, papaya plants have to face many environmental factors during their life. This study aims to identify and analyze the HSP90 gene family in papaya by bioinformatics method. A total of seven HSP90 genes have been identified in the genome of papaya (Carica papaya L.) by using the bioinformatic methods. The full-length genomic sequence of papaya HSP90 genes were ranging from 2650 to 8136 nucleotides, non continuous coding, with number of intro ranging from two to 19. The predicted protein sequences included from 348 to 796 amino acids, according to the molecular weight ranged from 39.92 to 90.61 kDa. Among seven CpHSP90, the two CpHSP90-1 and CpHSP90-4 were considered pseudogenes due to their small size. These proteins were acidic with a pI value ranging from 4.69 to 5.42, except CpHSP90-1 (pI 7.03). Based on the protein structure, subcellular localization and the phylogenic analysis, the papaya HSP90 were divided into two groups, I (cytoplasmic HSP90, four members) and II (organelle HSP90, three members). Analysis of transcriptomes showed that the papaya HSP90s were differentially expressed in different tissues at different development stages. In which, most of the papaya HSP90 is highly expressed in flower buds or in fruits at stage 2 or stage 3. CpHSP90-2 had the highest level of expression, followed by CpHSP90-5. In contrast, CpHSP90-1 was not expressed or very weakly expressed in these studied tissues. All of seven HSP90 genes of papaya were induced by freeze-thaw awakening treatment (in comparison with control treatment), among them, CpHSP90-1 was strongest induced by stress (12.13-folds), however, it was a pseudogene and had a very low level of basal expression. CpHSP90-2 had a high induction level (2.81- folds), and also had a high basal expression level compared to other HSP90 genes of papaya. The results of this work have an important significance and will serve as a base for the further research on gene cloning, functional analysis of HSP90 genes and breeding of papaya in response to environmental abiotic stresses and the development of this fruit crop.

Authors: Hoang Thi Hien Le
Published: February 2022

The twenty-first century is a century in which humans face many ecological risks and a century of emergence and development of environmental trends. Eco-criticism appeared with the purpose of warning people to exploit over what makes the earth more and more exhausted, “putting the biosphere into danger.” As a child growing in the Southwest region, Nguyen Ngoc Tu's works often show ecological consciousness and concern for environmental issues. Through collections of short stories such as Endless Field, Gorgeous sky Smoke, she is concerned about the lives of people and other creatures from environmental disasters. Based on the orientations of our predecessors, our topic will contribute to clarifying the relationship between people and the natural and social environment in the spirit of humanity and modernity. Compared to previous works on ecocriticism of Nguyen Ngoc Tu, the different topic is: Recreate the most honest views of people before environmental disasters - People indifferent or awake? Do people standstill or act? Do people hide or reveal? We want to delve into the psychological analysis, people's inner struggles when facing souls, thereby forcing people to find ways to “save” nature and protect the environment.

Published: February 2022

This article analyzes the current situation of the development of listening and speaking skills for children with a hearing impairment aged 3-6 years in inclusive kindergarten classes. The survey was conducted on 127 teachers who have worked with those children in 15 inclusive kindergartens in 05 provinces including Hanoi, Ninh Binh, Thai Nguyen, Yen Bai, and Quang Ngai. The survey results show that: Most of the teachers are properly aware of the role and meaning of the development of listening and speaking skills for children with hearing impairments in inclusive kindergarten classes. The teachers started to select and implement a number of contents and ways of the development of listening and speaking skills for children with hearing impairment in accordance with the general contents and methods specified in the early childhood education curriculum. However, due to the lack of in-depth training on inclusive education for children with hearing impairment, the teachers had no specific methods to support children in whole-class activities as well as individualized sessions. Therefore, building guidelines and organizing professional training courses for teachers on how to develop listening and speaking skills for children with hearing impairment is very essential.

EFL STUDENTS’ PERCEPTIONS OF 21ST CENTURY LEARNING SKILLS IN HIGHER EDUCATION
Authors: Duong My Tham , Hoang Viet hien
Published: February 2022

Twenty-first century learning skills (4Cs) are considered as indispensable learning and innovation skills that students should enhance in the classroom as a preparation for their future life in the 21st century. This paper, therefore, aimed to scrutinise the extent to which the 4Cs are important perceived by the third-year English majors at Ho Chi Minh City University of Economics and Finance (UEF). The questionnaire which was employed as the main research instrument to collect the data was administered to the thirdyear English majors (n=204). The data were quantitatively analysed by means of the software SPSS 20.0 (i.e., Mean and Standard deviation). The findings indicated a high rate of agreement on the 4Cs. Statistically, the mean scores of communication, collaboration, critical thinking, and creativity skills were high, which means that they mostly acknowledged the crucial role of these skills in their learning. In particular, they highly valued diversity in communication (e.g., verbal and non-verbal communication in diverse contexts, effective communication in cross-cultural environments), mutual respect and appreciation, a connection between the knowledge gained from the university and real-life experiences, and innovations. The preliminary findings probably not only practically contribute to the 4Cs development in the research context and similar EFL contexts, but they also bring theoretical contributions to the literature about the 4Cs in EFL teaching and learning.

Teaching is research-oriented in accordance with the requirements to develop students’ competencies in Science subject. The appropriate level of research-oriented teaching for primary students is research drilling teaching. Based on the 4-step process of scientific research, the research has built a corresponding process of teaching sex education. In which, the students are put into a problem situation and create an opportunity for all students to actively participate in the lesson by proposing diverse questions and ideas. The lesson plan for “Puberty and puberty hygiene” of the “Humans and health” topic in Science subject 5 has been built and experimented with. The experimental results prove that the initial process and lesson plan have met the requirements of the Science curriculum. This is the basis for gradually forming and developing specific scientific competencies, general competencies and qualities for students in Science subject (2018).

The problem of constructing the ideal in the moderate and radical traditions of Russian liberalism at the end of the 19th century
Authors: Sharova Veronika
Published: February 2022

The article is devoted to the formation of the ideal in the moderate and radical traditions of Russian liberalism in the last quarter of the 19th century. This period is fundamentally important in the evolution of liberal thought and movement: at this time, the liberal policies of Russia at the beginning of the twentieth century were formed. The problem of constructing a socio-political ideal allows us to show polarization within the liberal tradition. Based on the analysis of political journalism and documents of personal origin, the author comes to the conclusion that the moderate liberal tradition followed the idea of personal improvement and was guided by the development of the existing political system. The radicals highlighted the social ideal, assumed a change in the political system and did not exclude the possibility of revolution. The research results can be used both in historical research and in other humanities.
Historical consciousness of the Modern era and political projectivity
Authors: Fyodorova Maria
Published: February 2022

The article is dedicated to the analysis of the genesis of the idea of a socio-political project and a social ideal in the philosophical thought of Modernity. The author expresses and substantiates the assumption that the emergence of these ideas in their close connection with the idea of progressivism was due to changes in the historical experience of modern human, facing the horizon of the expected future. On the other hand, the special connection established in modern times between theoretical reflection and practical activity endows political reflection with the features of projective thinking. However, progressivism and projectivity turned out to be those moments of historical consciousness that underwent significant changes in the second half of the twentieth century. The main features of the projectivity of our time are determined and the main points of responsible thinking about the future are highlighted.
The social ideal as an a priori concept of the Russian philosophy of history (Second half of the XIX – early ХХ century)
Authors: Sizemskaya Irina N.
Published: February 2022

The article fixes two dimensions of the problem of the social ideal: axiological and philosophical-historical. The social ideal is considered by the author as an a priori concept of philosophical and historical knowledge, which asserts the scientific legitimacy of assessing historical events and social reality from the standpoint of moral consciousness and universal human ideas about what should be done. The author shows that its inclusion in the scientific apparatus of the philosophy of history allows us to understand the historical movement of mankind and individual peoples as an integral being, the semantic core of which is the movement from the past to the present and from it to the future in the direction of perfect forms of social community. Such a direction was presented in Russian philosophical thought by studies that correlated the movement of history and the accompanying social transformations with the interests of development and the creative self-realization of a person. This initiated attention to a new vector of consideration of the social ideal and, in this context, to historical epistemology as part of the scientific philosophy of history. In this regard, the author refers to the research of N.I. Kareev and his analysis of the role of "accidental" and "legitimate" subjectivism in the interpretation of the historical process.
Asociaciones de foraminíferos aglutinados de la Formación San Cayetano en el Cinturón Plegado de San Jacinto (Norte de Colombia)
Authors: Torres Gustavo Adolfo , Patarroyo German David , Veloza Gabriel , Mora Josue Alejandro , Gomez Diego Fernando
Published: February 2022

El Paleógeno del Cinturón Plegado de San Jacinto (CPSJ) corresponde a una sucesión sedimentaria heterolítica, lo cual ha causado que el registro de microfósiles sea poco estudiado, particularmente para el Paleógeno Inferior. Este es el caso de la Formación San Cayetano, que por medio de las asociaciones de foraminíferos, ha sido interpretada como una unidad de edad Paleoceno-Eoceno temprano, y depositada en un ambiente de tipo turbidítico. Sin embargo, los niveles donde se han reportado los foraminíferos son intervalos discretos y un incremento en los estudios sedimentológicos y paleontológicos (macrofósiles), ha causado que tanto el rango cronoestratigráfico como los ambientes de depositación de la Formación San Cayetano vengan siendo objeto de debate. Teniendo en cuenta que las asociaciones de foraminíferos en esta unidad corresponden principalmente a formas bentónicas aglutinadas, se presenta el estudio taxonómico detallado de los especímenes más representativos en varias secciones que comprenden sedimentitas de la Formación San Cayetano. Las morfoespecies de foraminíferos descritas en este trabajo corresponden a especímenes poco diversos, con abundancias y preservaciones moderadas, los cuales comprenden principalmente formas aglutinantes tubulares y multiseriales. Aunque los taxones descritos representan en buena medida al tipo de foraminíferos reportados para la Formación San Cayetano, abarcando un intervalo de tiempo Paleoceno tardío-Eoceno temprano, algunos de los taxones referidos en este trabajo, como Aschemocella subnodosiformis, Bathysiphon eocanicus, Budhashevaella trinitatensis, Nothia lattissima o Reticulophragmoides jarvisi, ayudarían a restringir el rango de edad del nivel donde se encuentren. Igualmente, el tipo de foraminíferos encontrados confirma la interpretación previa de ambientes turbidíticos (flysch-type foraminiferal assemblages) o en su defecto, ambientes con una alta inestabilidad en el substrato. Por ende, estos resultados refuerzan la idea de que a futuro se clarifiquen las relaciones estratigráficas de los niveles de foraminíferos, con la de aquellos intervalos que han sido interpretados como depositados en ambientes proximales.
Archaic Novelty: New Phraseological Units of Russian Youth Slang
Authors:   Lomonosov Moscow State University, Gudkov D.B.
Published: February 2022

The article considers the figurative basis of new phraseological units of the Russian language, which are actively represented in youth slang, but, despite their wide distribution, have not yet been reflected in the “classical” lexicography. It is noted that these units are particularly difficult for foreign speakers studying Russian. Within the framework of the linguoculturological approach, the traditional Russian cultural codes on which the semantics of these phraseological units are based are distinguished.

Eternity and immortality in the “Letter Book” are not abstract, but actually exist in the world itself.
Test control in Russian as a foreign language from the standpoint of synergetic linguodidactics
Authors:   Peoples’ Friendship University of Russia, Vladimirova Tatiana
Published: February 2022

The article is devoted to the problem of improving the testing system in the Russian language at the pre-university stage of preparing foreign students for study in Russian universities. For this purpose, the work examines the linguodidactic potential of the synergetic approach, which actualizes the potential of the subject-subject interaction of the teacher and students. The implementation of this direction contributes to the creation of conditions that will bring the development of standardized test materials and testing to a qualitatively new level.
