Published: December 2021

Synchrotron radiations (SR) are emerging as a real-time probing tool for the wide range of applied sciences. Since the beginning of 1990s, synchrotron-based techniques have become increasingly employed in various fields of life science. The unique properties of Synchrotron radiations break the limits to characterize the material properties than previous laboratory based techniques. The use of SR in soil sciences also has increased dramatically in the last decade. SR techniques are used to assess soil physical, chemical and biological properties. Besides that SR techniques are also used in soil pollution studies and rhizosphere science. So this paper intends to explain about the instrument synchrotron, its techniques used in soil science and applications in soil science. Furthermore the paper tries to elucidate a few relevant researches in soil science which involves SR techniques.

Published: December 2021

A Doctoral Research was conducted for two consecutive years (2011-2012 and 2012-2013) on fine texture soils of agricultural college farm, Bapatla to find out the residual effect of different sources of nutrients applied to preceding rice on P content in maize at different growth stages. The experiment was laidout in a Randomized Block Design in Kharif season with four treatments. The treatments consisted of M1 (RDF - Control), M2 (10t FYM ha-1 + RDF), M3 (1.5t vermicompost ha-1 + RDF), M4 (Green manuring + RDF). During the immediate Rabi, the experiment was laid out in a split-plot design without disturbing the soil for succeeding maize with the four treatments given to Kharif rice as main plot treatments and each of these divided into five sub-plots to receive five levels of fertilizer NPK application viz., N1 - 75%NPK, N2 - 100% NPK, N3 - 125% NPK, N4 - 150% NPK and N5 - 175% NPK for succeeding maize. Data collected on P content in maize at different growth stages was significantly increased with the application of 100% NPK in combination with FYM @10t ha-1 to preceding rice crop, irrespective of the NPK levels applied to succeeding maize crop. However, it was on par with that of green manuring together with 100% NPK during both the years of the study.

It is possible to prepare soil fertility maps by use of MS office (word / Excel / power point) using village land map with survey numbers in excel sheet. The village Itagi is a part of Ranebennur taluk, Karntaka, India which has major soil types black clay soil and red sandy loam soil. Problem cause analysis indicated the low soil fertility status and unscientific use of fertilizers as the reasons for low crop yields. In 86 random locations (on selected survey numbers) soils are sampled, labeled and processed. Samples are analyzed for soil pH, electrical conductivity (EC), organic carbon, macro nutrients and micro nutrients. The status of soil for each property is classified into three classes. Looking to each survey number on the excel sheet, the polygons are filled with colours for respective classes (low, medium and high). The results revealed that 69 per cent of samples belong to alkaline pH and oil salinity is medium in the area. Available nitrogen and phosphorous are low (59 % and 48 %) and available potash is medium (70 %). Organic C belongs to medium to low category. B belongs to low category, while majority of the soils have low status of other micronutrients except Cu. The DEXCEL maps prepared for pH, Av. NPK and organic C indicate the status of soil properties in the village land on respective survey numbers. Which side of the village, the particular soil parameter belongs to low category can be observed and suitable measure can be adopted for the management.

Published: December 2021

Cordia gharaf is a small bushy tree or a large shrub belonging to family Boraginaceae found growing in the arid and semi-arid tropics. It is mainly important due to its ethnopharmacological and chemotaxonomic properties but also has edible fruits which contribute significantly to the food and energy needs of rural populations. Fruits are sweet and mucilaginous and much relished by children. These are either eaten raw or cooked, often put in porridge and used as a sugar substitute. They are often sold in the local market of Jodhpur, Rajasthan, at about Rs. 80-100/- per kg. Owing to edible and medicinal importance of fruits these were collected and analyzed for their nutritional composition. Morphological data was recorded and ash, protein, sugar, fat, dietary fibre and mineral content were determined by standard AOAC methods. Fruits were found to be rich in protein (11.37-12.85%), sugar (8.14-15.13 %) and minerals viz., Ca 0.27-0.76 mg/100g), Fe (6.7-11.85 mg/100g) and Zn (2.0-2.7 mg/100g), Mg (60.7-86.5 mg/100g), Mn (0.3-1.1 mg/100g) and Cu ( 1.3-1.6 mg/100g).

Studies on induced genetic variability in M1 generation for quantitative traits in chickpea (Cicer arietinum L.)
Authors: Anusha Induri , Lal Gabriyal M.
Published: December 2021

Mutations were induced in three chickpea genotypes, ICC-15936, BRC-1104-127 and C-108 using sodium azide (SA) as a mutagen. The immediate effects of mutagenic treatments were measured in terms of biological damage caused in M1 generation. All the mutagenic treatments brought reduction in seed germination, seedling length and plant survival. Such reduction, with an exception of plant survival, were found to be depended upon the dosage of the concentration.High GCV and PCV in chickpea germplasm were observed for number of effective pods per plant, number of secondary branches per plant, number of pods per plant, seed yield per plant, plant height, number of primary branches per plant, seed index, harvest index, biological yield per plant. High estimate of heritability coupled with high genetic advance as percent of mean was recorded for number of effective pods per plant, number of secondary branches, number of pods per plant and seed yield per plant. High values for heritability indicates that it maybe due to higher contribution of genotypic components. Traits exhibiting high heritability coupled with genetic advance as percent of mean suggest that the traits are governed by additive gene action, equal contribution of additive and non-additive gene action respectively.

Animal husbandry as the driver of progress in India and Kerala
Authors: Chacko Biju
Published: December 2021

The dairy sector, which contributes to 21 per cent of the value of the agriculture and allied sectors in India, is the growth propeller of the rural economy of the country. However, extraneous factors beyond the farmer’s control, for instance climatic variations such as low rainfall and heavy drought; fluctuating and many a times low prices for produce and exploitation by middlemen have cast a gloomy spell over the sector, indicating that the prospects of the agricultural sector are gloomy, as evinced by the fact that in the year 2014-15, the sector showed a negative growth (-0.20 %), from where it is struggling hard to pick up, indicating that its prospects are more or less saturated. This augurs well for the dairy sector, which grew annually at the rate of around five per cent, every year, since 2014-15 and has started asserting great and added significance, as a livelihood ensurer to the poor farmers of the country. The state of Kerala is a demographically and socially well advanced state located in the South Western region of India, having 3.34 crores of people with a population density of 859 persons per square kilometre, the third among the states in India. The present scenario, via-a-vis, both India and Kerala, with respect to feed, the costliest component, which accounts for more than 80 per cent of any animal husbandry enterprise, fodder, management practices, reproduction, disease incidence and market of dairy and meat products are discussed thread bare, by analysing the present situation, pointing out lacunas, if any and suggesting feasible, scientific and practical solutions. These recommendations for the upliftment of the sector, if implemented at the grass root level, would definitely help animal husbandry and dairying in becoming the driver of progress in India and Kerala and will speed up our onward march towards the ultimate goal of ‘Aatmanirbhar Bharath’.
A redução da preposição para em relação à palavra precedente
Authors: Huback Ana Paula
Published: December 2021

Neste artigo, analisa-se a redução da preposição para a pra no português brasileiro em sequências de (palavra anterior + para ou pra). O Corpus LAEL de língua falada foi adotado para fazer buscas por essas sequências. Considerando-se as 30 sequências mais frequentes de (palavra anterior + para ou pra), análises estatísticas foram realizadas para observar que fatores interferiam nessa redução. Os conceitos de frequência da sequência (Krug 1998, 2003, Bush 2001), frequência relativa (Torres Cacoullos 2006) e frequência de ocorrência (Bybee 2002a, 2002b, 2006) foram utilizados para verificar se a repetição das palavras em alguma dessas formas desempenhava algum papel nas sequências em que para se reduz a pra. Observou-se que a frequência relativa favorece a redução de para a pra, juntamente com classe de palavra, número de sílabas e tonicidade. A partir desse fenômeno, discute-se a possível estocagem de sequências de duas ou mais palavras no léxico mental dos falantes, bem como as consequências disso para processos de variação e mudança linguística.

Koronapandemian vaikutukset jatko-opintoihin. Humanistis-yhteiskuntatieteellisen tiedekunnan keväällä 2020 ja 2021 toteuttaman kyselyn tulokset
Authors: Tammelin-Laine Taina , Ojala Jari , Niskanen Heli
Published: December 2021

Covid-19-pandemian vaikutuksia elämän eri osa-alueille on jo tutkittu ympäri maailman. Jyväskylän yliopiston humanistis-yhteiskuntatieteellisessä tiedekunnassa haluttiin saada parempi käsitys pandemian ja siitä aiheutuneiden poikkeusolojen vaikutuksista jatko-opintoihin ja niiden suorittamiseen. Niinpä tiedekunnassa päätettiin toteuttaa keväällä 2020 jatko-opiskelijoille suunnattu kysely, jossa selvitettiin esimerkiksi poikkeusolojen vaikutuksia opintojen edistämiseen ja vastaajien poikkeusolojen aikana kohtaamia haasteita jatko-opintojen eri osa-alueilla. Kyselyyn vastasi 164 jatko-opiskelijaa tiedekunnan eri laitoksilta. Koska poikkeusolot pitkittyivät, tiedekunnassa päätettiin toistaa kyselytutkimus vuotta myöhemmin, keväällä 2021. Tähän kyselyyn vastasi 78 jatko-opiskelijaa. Tässä raportissa esitellään kootusti kummankin kyselyn tulokset ja niiden pohjalta koostetut ehdotukset toiminnan kehittämiseksi.
Kyselyvastausten perusteella voidaan sanoa, että pandemian ja sen aiheuttamien poikkeusolojen vaikutus jatko-opintoihin polarisoituu: Toisten opintoihin poikkeusolot ovat vaikuttaneet merkittävästi, kun taas toisten mielestä vaikutuksia on ollut vain vähän tai ei lainkaan. Myös vaikutusten koettu laatu vaihtelee vastaajittain: Jotkut vastaajista kokivat pandemian vaikuttaneen positiivisesti esimerkiksi niin, että tutkimukseen keskittyminen on mahdollista aiempaa paremmin. Toisille poikkeusoloista on ollut huomattavasti enemmän haittaa kuin hyötyä, ja pandemian takia on voinut joutua esimerkiksi keskeyttämään aineistonkeruun tai ulkomaille suuntautuneen tutkimusvierailun. Keskeisimmäksi pandemian haittavaikutukseksi jatko-opintojen kannalta nousi niin paikallisen, kansallisen kuin kansainvälisenkin verkostoitumisen mutkistuminen. Lisäksi poikkeusolojen pitkittyminen on lisännyt verkostoitumiseen liittyviä haasteita.
Kyselyiden tulosten perusteella näyttää siltä, että olisi hyvä tarttua kehittämismielessä ainakin seuraaviin kysymyksiin:

1. Pandemiasta riippumatta jatko-opintojaan etäyhteyksien kautta edistävien opiskelijoiden lisätuen tarve ja yliopistoyhteisöön sitoutuminen
2. Tarvittaessa tarjottava matalan kynnyksen etäohjaus, jossa keskiössä jatko-opiskelijan hyvinvointi
3. Yliopistoyhteisöön kuulumisen kokemuksen lisääminen vertaistuella
4. Poikkeusolojen aikana hyväksi havaittujen käytäntöjen säilyttäminen jatkossakin.

Authors: YILMAZ Yakup
Published: December 2021

Teaching-learning activities carried out face-to-face in physical classrooms in higher education have been moved to the online environment due to the Covid-19 pandemic obligation. It is obvious that students' learning experiences and perceptions need to be researched empirically in order to optimize higher education strategies that have been moved to the online environment. Data were collected from 451 students studying in different departments in two education faculties in order to reveal the relationship between their satisfaction in the e-learning environment and their perceived learning experiences and using online self-regulation strategies based on the autonomous movement of students in the online environment. Descriptive analyses and path analysis were applied in order to answer the proposed research questions. As a result of this structural equation modeling, a relationship was determined between online self-regulation skills, goal setting and help seeking sub-factors, and satisfaction, goal setting, task strategies and self-evaluation sub-factors and perceived learning. In addition, a direct relationship was determined between satisfaction and perceived learning, supporting previous studies. With this research, it is thought that higher education institutions, administrators and instructors carrying out online teaching and learning activities will provide new perspectives on satisfaction and perceived learning outcomes when students' self-control skills are supported.

Science and technology advancement in the 21st Century requires several life skills that everyone must learn; critical thinking is one of them. Critical thinking is often defined as a process of metacognition that increases the chances of solving a problem. This research attempted to implement NASA Science as Interactive Multimedia to enhance students' critical thinking in learning Solar System. Interactive Multimedia is student-centered, allowing students to play an active role in learning to promote students' critical thinking skills. This study used a pre-experimental method with one group pretest-posttest design. The sampling used was convenience sampling, which participated in 42 7th grade students of a private school in Bandung. The Objective Test was used as a research instrument for both pretest and posttest. These test items were designed according to Facione's indicators of Critical Thinking Skills. Based on the analysis result, the value of g is 0.48. According to the Wilcoxon test, the hypothesis in this research is accepted. The value of Asymp. sig. (2-tailed) is 0.00, with a sig. α = 0.05. Thus, this research shows that: There is an enhancement of students' critical thinking after using NASA Science in learning Solar System.

The Wisdom of God as the Eternal Feminine: Dante and V.S. Solovyov on Sophianic Unity
Authors: Pigalev A.I.
Published: December 2021

The paper deals with the continuity of ideas concerning the Eternal Feminine and Sophia as the Wisdom of God from the point of view of Dante Alighieri and Vl.S. Solovyov. The analysis focuses not so much on the very notion of Sophia as on the meaning, origins, and contexts of their conception of Sophianic unity. The latter, being an ideal form of reducing a multitude to a unity, is considered as either an alternative or a supplement to the model of totality that reproduces the binary and hierarchical structure which at the social and political level is considered to be the pattern of imperial centralism. The study proceeds from the consequences of Dante’s negation of the difference between the spiritual sense of the Holy Scriptures and the literary sense of secular poetry. It is shown that for Dante it was necessary, first of all, to understand under whose inspiration and guidance he composed his verses, which gave particular importance to the image of a guide in his magnum opus. I show that in this context Dante turned to the intuitive representation of the feminine idea as a guiding principle that was personified by Beatrice, although Dante did not use the term “Sophia” and could not use the term “the Eternal Feminine,” which did not yet exist at the time. The disputes in Dante’s time on the essence of monarchy are considered in connection with his understanding of femininity as the guiding principle of such a unity of humanity that could reject a rigid hierarchy and, thus, free itself from imperial centralism. It is pointed out that the social and political aspects of the all-encompassing Sophia, which also resolves contradictions as a supplement to the intrinsically contradictory Logos, were given great importance in Solovyov’s philosophy. The paper concludes that it was Solovyov, who, having identified Sophia with humanity as a whole, created the presuppositions for a detailed study of the structure of Sophia’s unity. This study ends with a discussion of the validity of the convergence of a non-hierarchical Sophianic unity with the deconstructive strategies of modern philosophy, the aim of which is the elimination of binary oppositions and hierarchies from the gender context.
Dante’s Models in Romantic Music
Authors: Zenkin K.V.
Published: December 2021

Dante’s impact on music has been studied completely enough, but so far mainly in an empirical and descriptive way. The article examines the works of romantic composers of the 19th - early 20th centuries, based on the plot of Dante’s “Divine Comedy”: Liszt’s fantasy-sonata “After reading Dante” and the “Dante-Symphony”, the “Francesca da Rimini” by Tchaikovsky (symphonic fantasy) and Rachmaninoff (opera). The author analyses compositional and stylistic models of the romantic music inspired by Dante’s poetry as a system, which is relevant for modern musicology, in particular, for the theories of musical language, style, and musical meaning. Along with the traditional musicological methods of analysis of form and intonational dramaturgy, an interdisciplinary methodology is applied, associated with the coverage of the entire system of musical compositional prototypes as a structuring of meaning. This has a pronounced narrative poetic nature in romantic music. The results of the study demonstrate a system of structural and semantic invariants (secondary, musical models) conditioned by Dante’s figurative world and manifested in melody, harmony, fret organization, composition. The conclusions of the article reveal the roles of Dante’s models of the world in the works considered in the following aspects: in the process of extreme intensification of the contrasts of romantic music in the semantic coordinates of “Hell – Paradise”; “Love – Death”; in the approval of the concept of Liebestod; in the creation of new, extreme expressive possibilities for the given style, which significantly expanded the idea of the boundaries of beauty and caused transformations in musical sound (harmony, texture, melody); in the formation of stable idioms of romantic music from Liszt to Rachmaninov; in the modification of the structures of a one-part sonata, of the cyclic symphony, and of opera, which have received the quality of a vectorial dramaturgical process and open dramaturgy.
Interpretations of Dante’s Esotericism in the Italian and French Studies in the Middle of the Nineteenth and the Second Half of the Twentieth Century
Authors: Medovarov Medovarov M.V.
Published: December 2021

This article has a historiographic and methodological nature and is devoted to the problematic interpretations of the esoteric content of Dante’s ideas and works by French and Italian scholars from the middle of the nineteenth century to the second half of the twentieth century. Various definitions of Western esotericism are discussed in the light of contemporary approaches. The current interest in the study of Dante’s esotericism and the relevance of this topic are substantiated. The tradition in the interpretation of Dante's esotericism in Italy and France can be traced back to the occultists of the 19th century, who referred to each other's works: G. Rossetti, E. Arou, F. Boissard, J. Péladant, G. Pascoli and others. It has been demonstrated that the studies of Dante's esotericism during 1920s reached a new level of quality, which was adequate to the contemporary scientific requirements for Dante studies: in Italy, this happened in the person of Luigi Valli and his students, Arturo Reghini and then Julius Evola; and in France, at the same time, in the person of René Guénon. The criticism of Valli in the works by Guénon is analyzed in detail. The context of Dante's interpretation by Guénon is revealed in connection with the issue of Templar, Rosicrucian and Islamic influences (Sufism, Arab Neoplatonism). In this respect, a significant difference of tones was observed in the perception of Dante's esotericism within the general paradigm of integral traditionalism between Guénon and his Italian colleagues Julius Evola and especially Guido de Giorgio, whose fundamental work is still unknown to Russian scholars. An intense politicization of the perception of Dante's heritage by Evola and de Giorgio is also remarked in this article. Special attention is then paid to the study of Dante's esotericism by one of the leading Roman Catholic theologian of the twentieth century, Romano Guardini, who engaged a polemic correspondence with the integral traditionalists. Based on the results of our study, it was concluded that the research of Dante's esotericism by French and Italian authors for more than a hundred years can be characterized as a continuous chain of dialogue and polemics of various authors who knew about each other's works and used the appropriate links.
A.N. Ostrovsky and F.M. Dostoevsky: to the History of the Relationship
Authors: Edoshina I.A.
Published: December 2021

The article reconstructs the relations between two contemporaries, two classics of Russian culture – Alexander Ostrovsky and Fyodor Dostoevsky. The relations are considered in the dynamics of their development. Despite the fact that contemporaries of Ostrovsky and Dostoevsky noted the playwright’s critical perception of Dostoevsky’s work, the emphasis is placed on the friendly nature of their relationship, the proximity of their aesthetic views, and the commonality of their creative framework. The article stresses that the proximity of their aesthetic views on artistic creativity will become the basis for Ostrovsky’s cooperation with the Dostoevsky brothers’ journal “Vremya” (Time). The research undertaken here analyzes the reasons for the termination of this cooperation and the nature of further relations between Ostrovsky and Dostoevsky, their mutual assessment of each other’s creativity. As a result, it is noted that although Dostoevsky did not enter Ostrovsky’s inner circle, in his plays the playwright addressed the issues that worried both of them.
Creating the Conditions for Climate Resilience: A Community-Based Approach in Canumay East, Philippines
Authors: Cash Corrine
Published: December 2021

People who reside in informal settlements in the Global South are most vulnerable to extreme weather events and their consequences, such as flooding, landslides, and fires. Those located in coastal areas face severe challenges from seasonal and typhoon-induced flooding. Research shows that uncertain land rights exacerbate community vulnerability because residents are under constant threat of eviction by private sector actors or the state. Individual and community upgrading is rarely possible in such a situation. This article focuses on the efforts to secure tenure and upgrade their community by the residents of Sitio Libis, located in Canumay East, City of Valenzuela, Philippines. The study demonstrates that while community-based approaches require skills and capacities of community members, enabling conditions created by government and/or NGOs are required for transformational outcomes. While the people of Sitio Libis did not conceptualize their efforts in terms of climate change adaptation, their success suggests the possibility for smart partnerships among state-civil society/private sector actors to emerge in support of small-scale climate action.
Identifying the Social Urban Spatial Structure of Vulnerability: Towards Climate Change Equity in Bogotá
Authors: Barbosa Vasco , Suárez Pradilla Mónica Marcela
Published: December 2021

The constant modification of land use, economic instability, environmental factors, and social behaviour changes among the inhabitants of big cities characterize current urbanism. In Colombia, land-use planning processes supported by geographical information systems are a recent phenomenon and the legal instruments of spatial planning are inadequate in most municipalities. Moreover, socio-spatial equity represents a challenge for Latin American cities in which there is increasing awareness of the role that spatial planning plays. Consequently, the question arises as to how the urban spatial structure and organization contribute to an inclusive and equitable socio-spatial evolution, considering climate change impacts. The case study analysed in this article focuses upon the northern limits of the city of Bogotá. Therefore, this research aims to define the ideal balance of urban land-use distribution between social stratum classification and the vulnerability of the communities seeking to better adapt to climate change. We propose a methodological approach of analysing spatial syntax and the (social) intensity of activities and infrastructure, which enables us to characterize the urban structure itself and identify vulnerable urban instances. As a result, we find that the urban network with low values presents spatial unpredictability in its pattern, constraining equitable development based on the urban morphology of the city. This research allows us to conclude that the degree of vulnerability encountered by the social urban spatial structure is higher in expansion areas than in central areas of the city.
The Equity Dimension of Climate Change: Perspectives From the Global North and South
Authors: Seasons Mark
Published: December 2021

The articles in this thematic issue represent a variety of perspectives on the challenges for equity that are attributable to climate change. Contributions explore an emerging and important issue for communities in the Global North and Global South: the implications for urban social equity associated with the impacts caused by climate change. While much is known about the technical, policy, and financial tools and strategies that can be applied to mitigate or adapt to climate change in communities, we are only now thinking about who is affected by climate change, and how. Is it too little, too late? Or better now than never? The articles in this thematic issue demonstrate that the local impacts of climate change are experienced differently by socio-economic groups in communities. This is especially the case for the disadvantaged and marginalized—i.e., the poor, the very young, the aged, the disabled, and women. Ideally, climate action planning interventions should enhance quality of life, health and well-being, and sustainability, rather than exacerbate existing problems experienced by the disadvantaged. This is the challenge for planners and anyone working to adapt to climate change in our communities.
