The 4-m International Liquid Mirror Telescope (ILMT) is presently (March-June 2017) being erected on the ARIES site in Devasthal (Uttarakhand). We describe and illustrate in the present paper its different components. The ILMT will be used in the Time Delayed Integration (TDI) mode to carry out a deep survey and high S/N photometric and astrometric observations of solar system, galactic and extra-galactic objects within a narrow (24’) strip of sky. In principle, the ILMT should detect and regularly monitor more than 50 multiply imaged quasars. It will also detect numerous supernovae (see Kumar et al., these proceedings) as well as space debris (see Pradhan et al., also in these proceedings).

Published: January 2022

High temporal resolution observations enable the study of rapid phenomena such as the flux varia¬tions in binary system objects, e.g. cataclysmic variables, compact binary systems, the flux variations in young star clusters, stellar occultations and more. The 2.4-m Thai National Telescope (TNT) is ideally suited for this niche research, being the largest facility in Southeast Asia and being equipped with ULTRASPEC, a high-speed imager based on a low-noise frame transfer electron-multiplying CCD. In the sub-window mode, ULTRASPEC can record uninterrupted sequences with frame rates as fast as few milliseconds. We present some of the key results obtained in the area of high time resolution with ULTRASPEC. We also present the results of a recent worldwide campaign to observe the current series of lunar occultations of Aldebaran (α Tauri) carried out in close collaboration with the Devasthal facilities, the out-of-eclipse variations on the post common-envelope system J1021+1744, and pre-main-sequence variables in young open cluster Stock 8.

Published: January 2022

Solar system astronomy would be an important field of study with the 3.6-m Devasthal Optical Telescope (DOT) and the 4-m International Liquid Mirror Telescope (ILMT). In this contribution, we highlight the work that could be done in reaching a better understanding of the Solar system and its constituents - particularly the minor bodies and other smaller objects. There may be a large number of very faint objects in the vicinity of the Earth orbit. In fact only recently a 'second moon' of the Earth has been found and has been designated 2016 H03. This is a quasi-satellite with the same period of revolution around Earth and Sun. There could be many such objects and it is important to have a full characterization and understanding of these potentially hazardous objects. They are generally fainter than 18th magnitude and one would need a lot of telescope time to fully characterize these objects using techniques of spectropolarimetry. In a similar fashion, a deep census of the Kuiper Belt Objects and the TNOs is needed. In this census, the concept of pencil beam surveys could be extended to cylindrical transit imaging technique available with the 4-m ILMT.
Investigating Extra-solar Planetary System Qatar-1 through Transit Observations

Published: January 2022

We report the results of the transit timing variation (TTV) analysis of the extra-solar planet Qatar-1b using thirty eight light curves. Our analysis combines thirty five previously available transit light curves with three new transits observed by us between June 2016 and September 2016 using the 2-m Himalayan Chandra Telescope (HCT) at the Indian Astronomical Observatory (Hanle, India). From these transit data, the physical and orbital parameters of the Qatar-1 system are determined. In addition to this, the ephemeris for the orbital period and mid-transit time are refined to investigate the possible TTV. We find that the null-TTV model provides the better fit to the (O-C) data. This indicates that there is no evidence for TTVs to confirm the presence of additional planets in the Qatar-1 system. The use of the 3.6-m Devasthal Optical Telescope (DOT) operated by the Aryabhatta Research Institute of Observational Sciences (ARIES, Nainital, India) could improve the photometric precision to examine the signature of TTVs in this system with a greater accuracy than in the present work.
An F-type ultra-fast rotator KIC 6791060: Starspot modulation and Flares
Authors: Karmakar Subhajeet , Pandey Jeewan Chandra
Published: January 2022

Making use of the data obtained from Kepler satellite, we have analysed an F-type ultra-fast rotator KIC 6791060. We derive a rotational period of 0.34365 ± 0.00004 d. Multiple periodicity with a period separation of ∼0.00016 d was detected, which appears to be a result of the relative velocity between the multiple spot-groups in different stellar latitudes due to surface differential rotation. During the observations, 38 optical flares are detected. Energies of these flares have been found to be in the range of 1031−33 erg. Preliminary results of surface temperature modeling indicate the existence of two active longitudes on the stellar surface.
The multi-messenger approach to particle acceleration by massive stars: a science case for optical, radio and X-ray observatories
Authors: De Becker Michaël
Published: January 2022

Massive stars are extreme stellar objects whose properties allow for the study of some interesting physical processes, including particle acceleration up to relativistic velocities. In particular, the collisions of massive star winds in binary systems lead notably to acceleration of electrons involved in synchrotron emission, hence their identification as non-thermal radio emitters. This has been demonstrated for about 40 objects so far. The relativistic electrons are also expected to produce non-thermal high-energy radiation through inverse Compton scattering. This class of objects permits thus to investigate non-thermal physics through observations in the radio and high energy spectral domains. However, the binary nature of these sources introduces some stringent requirements to adequately interpret their behavior and model non-thermal processes. In particular, these objects are well-established variable stellar sources on the orbital time-scale. The stellar and orbital parameters need to be determined, and this is notably achieved through studies in the optical domain. The combination of observations in the visible domain (including e.g. 3.6-m DOT) with radio measurements using notably GMRT and X-ray observations constitutes thus a promising strategy to investigate particle-accelerating colliding-wind binaries in the forthcoming decade.
Variable stars in young open star clusters
Authors: Lata Sneh , Pandey Anil Kumar
Published: January 2022

We have carried out time series photometry of the some young open clusters NGC 1893, Be 59, NGC 7380, Stock 8 and NGC 281 to search for pre-main-sequence variable stars. We have detected several pre-main-sequence variables associated to the young open clusters with periods ranging from ~0.1 to ~50 days. These pre-main-sequence variables could be T Tauri stars. The association of these variable stars with the cluster has been established on the basis of two colour diagrams, a colour-magnitude diagram and spectral energy distributions. The brightness of classical T Tauri stars is found to vary with a larger amplitude in comparison to weak line T Tauri stars. It is found that the amplitude of pre-main-sequence variables decreases with increasing mass, which could be due to the dispersal of discs of massive stars. We have also detected several stars as main-sequence variables, which are classified either as slowly pulsating B stars, β Cep stars, δ Scuti stars or members of a new class of variable stars.

Radioactive decay of the late-time light curves of GRB-SNe
Authors: Misra Kuntal , Fruchte Andrew Steven
Published: January 2022

We present the late-time Hubble Space Telescope observations of two GRB associated supernovae, GRB 030329/SN 2003dh and XRF 060218/SN 2006aj. Using the multi-color data upto  320 days after the burst, we constrain the late-time decay nature of these supernovae. The decay rates of SN 2003dh are steeper than SN 2006aj. A comparison with two other GRB supernovae, GRB 980425/SN 1998bw and the supernova associated with XRF 020903, shows that the decay rates of SN 2003dh are similar to XRF 020903 and those of SN 2006aj are similar to SN 1998bw. The late-time decay rates are steeper than the 56Co56Fe radioactive decay rate (0.0098 mag day-1) indicating that there is some leakage of gamma-rays.

Stripped-Envelope Supernovae constitute the sub-class of core-collapse supernovae that strip off their outer hydrogen envelope due to high stellar winds or due to interaction with a binary companion where mass transfer occurs as a result of Roche lobe overflow. We present here the photometric and spectroscopic analysis of a member of this class : SN 2015as classified as a type IIb supernova. Light curve features are similar to those of SN 2011fu while spectroscopic features are quite similar to those of SN 2008ax and SN 2011dh. Early epoch spectra have been modelled with SYN++ which indicates a photospheric velocity of 8500 km sec-1 and temperature of 6500K. Spectroscopic lines show transitioning from H to He features confirming it to be a type IIb supernova. Prominent oxygen and calcium emission features are indicative of the asymmetry of the ejecta. We also estimate the signal to noise ratio of the 3.6m telescope data. This telescope is located at ARIES, Devasthal, Nainital at an altitude of 2450m. We also show the comparison plots of spectra taken with a 2m and 4m class telescopes to enlighten the importance of spectral features displayed by bigger diameter telescopes.
Apports de la syntaxe spatiale à la vérification de l’intégration d’un quartier d’habitat spontané dans le système urbain
Authors: Araba Mabrouk , Mazouz Said
Published: January 2022

À l’instar des autres villes algériennes, Bou-Saâda a connu une importante croissance démographique et un exode rural sous la pression des évènements politiques et socio-économiques marquant l’histoire de la ville et de la nation. Le rythme de construction des logements officiels n’a pu faire face à cette situation. Des quartiers d’habitat spontané ont donc vu le jour, tel que Maïtar. Ce dernier s’est implanté dans un site périphérique, enclavé entre parcs de production de matériaux de construction, montagne de Moubakhera,  dunes de sable et Oued Maïtar, avec une grande pauvreté en termes d’équipements publics et d’espaces de convivialité. Ce présent article aborde la vérification de l’intégration du quartier d’habitat spontané de Maïtar dans le système urbain de la ville de Bou-Saâda par le biais de la méthode de la syntaxe spatiale, théorie initiée par Bill Hillier et d'autres chercheurs à la Bartlett, University College of London, qui s’intéresse à l'analyse des configurations spatiales des objets architecturaux et systèmes urbains par la traduction spatiale des comportements sociaux à travers un ensemble d’outils et de techniques permettant l'aboutissement à plusieurs modèles interprétatifs de différents phénomènes sociaux et spatiaux. Cette théorie donne accès à certaines caractéristiques et propriétés des graphes, en permettant notamment une analyse plus poussée, au niveau local comme au niveau global [1]. L’application de cette analyse à travers les outils de la carte axiale et de la carte de « all line analysis » sur la ville de Bou-Saada a démontré la ségrégation du quartier de Maïtar par rapport au système urbain. Ces résultats s’interprètent par le nombre très limité des voies qui relie le quartier avec le système et l’isolement spatial dû à l’enclavement. Le réseau interne du quartier n’est plus perméable, il s’appuie sur un seul axe de distribution et d’organisation de l’espace, ce qui reflète une ségrégation et une faible connectivité au sein du quartier et avec l’ensemble du système urbain de la ville. L’espace dans son ensemble est moins fréquenté, il est donc insécurisé et se caractérise par une grande introversion.
Cultural and Sociocultural Elements of Language Learning for the Turkish Learners of English in Two Different Universities
Authors: TOMAK Burak
Published: January 2022

Culture is one part of the language learning process and it has been defined and categorized by several scholars. With the advent of social constructivism in education, the sociocultural learning theory has come to the foreground. Therefore, these two important concepts have affected the language teaching pedagogy. Thus, this study aimed at determining the cultural and sociocultural elements that were focused in language classes in two different universities in Turkey. Hence, for the purpose of this study, five students from a state university in Istanbul and five students from another state university in Eskisehir were interviewed to find out whether these elements were covered in the language classes of the School of Foreign Languages in these two different university contexts. Additionally, some other contextual factors that affected these learners’ sociocultural learning process were also questioned. The results showed that some aspects of culture were more stressed in language classes whereas some of them were neglected. Participants also stated that they benefitted a lot from the elements of sociocultural learning theory especially in terms of “scaffolding” as they cooperated with their peers whose level of language proficiency was higher than themselves to improve their language skills, especially writing and grammar.
Assessment of Antoni Gaudi's Design Approach on the Concept of Biophilia: Case of Casa Battlo
Authors: ÖZER BAŞ Gizem , KURNALI Melih
Published: January 2022

With the modernism movement, the diversification of design approaches has accelerated and, many methods focused on the solution of new problems have emerged. The design approaches, which move away from natural life and aim at the mechanical purposes of the function, have increased the longing of the people living in the cities for nature. In this sense, the biophilic design emerges as a new concept and aims to transfer nature to the building design in a direct and non-artificial way. The buildings of Antoni Gaudi, who had a design understanding far beyond his age, presented the reflections of nature in his unique ways. At this point, if Gaudi's approach to nature is questioned, his place in biophilic design, one of today's concepts, is a serious research topic. To what extent does the biophilic approach, which seeks to bring the new and modern together with nature, takes place in Gaudi's designs, which embody nature in a plastic and concrete sense. To what extent does the biophilic approach, which seeks to bring the new and modern together with nature, take place in Gaudi designs, which include nature in a plastic and concrete sense? The study aims to evaluate Casa Battlo, one of the Gaudi designs, through biophilic design criteria. For this purpose, biophilic design, Antoni Gaudi and his Works examined. The biophilic design criteria obtained because of the examination were used to evaluate Casa Battlo. Gaudi's Casa Battlo shows how the conceptually new term biophilia is at the core of this building. In this sense, the study shows how the conceptual essence of biophilia works like a spirit from the past that makes the structure permanent and unforgettable.

Published: January 2022

The practicum period is a crucial component of teacher education as it embodies the first phases into "real" teaching and thus provides a leap into professional transformation and growth on the side of pre-service teachers. Nevertheless, the COVID-19 pandemic jeopardized this period and placed the educational contexts at stake in providing that reality. Within this frame, the present study focuses on the research conducted on the practicum period of Turkish pre-service teachers of English during the pandemic. More specifically, the research question that the article addresses is “what is the nature of studies conducted about Turkish pre-service EFL teachers’ practicum period during the COVID-19 pandemic concerning their characteristics, methodologies and contributions to the field?” With the aim of answering the research question, the seven studies conducted in Turkey regarding the practicum during the pandemic were collected and analyzed as to their bibliographic features, methodological orientations, foci and context, with a scoping review methodology. This scoping review demonstrated both positive/beneficial and negative/challenging aspects of the pandemic period for the English language teacher education context of Turkey. The results of the present study displayed a wider lens in perceiving the English language teaching and teacher education settings during both such emergencies and transition from existing to 'new normal'.

Published: January 2022

This study aims to investigate how the students' university accommodates their local/regional language to the new language that they stay temporary for their study program at university. Two students were involved in this study from different regions in East Java which took four years of study in UNESA. They have different dialects from their regions and should adjust new dialects in Surabaya for their new environment. For this reason, this study wanted to know how students-university accommodates their home-language to Surabaya language as the place that they study at university. To do so, the researcher gained the data in depth-interviews that used structured interviewed techniques. Further, the analysis revealed that the university students changed their linguistic features because many reasons; they wanted to be approved in their community, they wanted to create meaningful or communicative communication with interlocutors, and they would get the same perceptions with their interlocutor. This research is beneficial for researchers who interest in the area of speech accommodation, especially in the Indonesian context since it is rarely conducted in Indonesia. Moreover, from the results of this study, it is to be more useful when the future study involved more students from different regions and different regional languages that can show many varieties of evidence for the speech accommodation process in a multilingual society.

Published: January 2022

Covid-19 pandemic may pose a factor that reduces learners’ motivation. The present study aims to investigate the differences between demotivation factors of public and private high school EFL learners during the Covid-19 pandemic. The present study applies a quantitative method to obtain its data by distributing a set of questionnaires adapted from Sakai and Kikuchi (2009) to 61 high school students from public and private high schools. The findings indicate that both groups of learners are mostly demotivated by inadequate school facilities, test scores, and teachers’ competence and teaching styles. It can be said that despite the differences in teaching location, learners may be demotivated by the same variables. Therefore, it seems imperative for teachers and teaching institutions to provide better school facilities, reduce learners’ anxiety during tests, and improve teachers’ competence and teaching styles to overcome students’ demotivation.  DOI: 10.26905/enjourme.v6i2.6519

The aim of this study is to know the effect of different percentages of chitosan added to drinking water on the weight and quality of quail meat, physical anatomy in terms of (the body of the long carcass, the girth of the chest, the length of the thigh bones, the thigh racket, the fullness of the chest), chemical analysis (protein, moisture, fat and ash) and sensory evaluation of quail meat. It was purchased 320 Iraqi-origin birds of quail and one day old. Chicks were randomly distributed to three equal groups' treatments and treated with chitosan and added to the drinking water: the first treatment (0.1 gm./L water only as a control treatment), the second treatment (0.2 gm./L of chitosan was added to the drinking water) and the third treatment (0.3 gm./L of chitosan was added to the drinking water).The results showed a significant difference (p≤ 0.05) between groups in carcass cutting, physical anatomy, measurement of carcass parts and chemical analysis, as well as a significant and clear improvement in the sensory characteristics of quail meat with a concentration of 0.2 gm./L chitosan. We conclude from this that adding low concentrations of chitosan to the drinking water of quail birds showed a significant difference in growth performance, meat quality, chemical composition, carcass weights and physical anatomy, as well as improving sensory characteristics and quality of quail meat.

Oleh karena itu, tahun 1929 melalui Is yang diundangkan dalam stbl no. 212 hukum Islam dicabut dalam tata hukum Hindia Belanda, karena Belanda ingin menguatkan kekuasannya di Nusantara ini serta ingin menjauhkan pengaruh Islam dengan cara menghapuskan hukum Islam. Faktor  sosial  budaya  juga  mempunyai  pengaruh  penting dalam  perkembangan  hukum  Islam  di  Indonesia,  dalam kenyataannya  telah mewarnai  produk-produk  pemikiran  hukum Islam,  baik  yang  berbentuk  kitab  fikih,  peraturan  perundang-undangan,  keputusan  pengadilan, maupun  fatwa-fatrwa  ulama. Hukum  Islam  dalam kenyataan  yang  sebenarnya  adalah  produk  pemikiran  hukum Islam  yang  merupakan  hasil  interaksi  antara  ulama  sebagai pemikir  dengan  lingkungan  sosialnya.  Meskipun  al-Qur’an  dan as-Sunnah  mempunyai  aturan  yang  bersifat  hukum,  tetapi jumlahnya  sangat  sedikit  di  banding  dengan  jumlah  persoalan hidup  yang  memerlukan  ketentuan  hukum,  terutama  dalam bidang  muamalah  yang  belakangan  ini  jumlahnya  meningkat pesat. Status hukum Islam dalam tata hukum di Indonesia secara yuridis formal masih lemah karena hanya Instruksi Presiden dan pemberlakuannya hanya bersifat fakultatif tidak bersifat imperatif.
Contribuciones para analizar las identificaciones sociales desde la teoría de la hegemonía
Authors: Fair Hernán
Published: January 2022

Este artículo analiza la cuestión de las identificaciones en la teoría de la hegemonía de Ernesto Laclau, centrándose en los cruces entre el líder y la función del objeto a de Lacan. A partir de una lectura de La razón populista, el trabajo propone una tipología innovadora basada en tres modos de identificación social para el análisis del discurso: la identificación directa con la figura del líder político; la identificación indirecta en torno al líder mediada a través de un objeto parcial que se convierte en significante vacío y ocupa el rol de punto nodal; y la identificación con ciertos valores, principios, demandas o ideales compartidos por el grupo u organización que funcionan como objetos a causa de deseo. En la segunda parte, se despliegan algunas herramientas teórico-metodológicas útiles para profundizar y fortalecer la investigación social de identidades y procesos sociopolíticos contemporáneos desde la teoría política del discurso.

El libro La Iglesia posconciliar en México. Claves para una comprensión, publicado por el maestro Sergio Padilla Moreno, profesor del Departamento de Formación Humana del Instituto Tecnológico y de Estudios Superiores de Occidente (ITESO), viene a contribuir a la discusión acerca de cuáles son las principales tendencias pastorales e ideológicas que la Iglesia mexicana ha develado tras la clausura del Concilio Vaticano II, pues pone sobre la mesa elementos para una interpretación sobre la actividad y discurso eclesial durante la segunda mitad del siglo XX.
Imre Szeman. On Petrocultures. Globalization, Culture, and Energy
Authors: González Salinas Omar Fabián
Published: January 2022

En medio del cada vez más alarmante calentamiento global, el agotamiento de las reservas de energías fósiles y la inminente necesidad de una transición energética menos dañina con el medio ambiente, científicos sociales –principalmente canadienses– han desarrollado las Energy Humanities, una corriente de estudio que propone analizar los paradigmas energéticos desde la perspectiva de lo cultural, lo político y lo estético. Como parte de estas investigaciones, se ha acuñado el concepto “petrocultura” para señalar que la sociedad moderna está condicionada psicológica y materialmente por el uso de energías fósiles, específicamente, por el petróleo. Aunado a ello, este concepto también se utiliza para referirse a las narrativas, representaciones y significados que se han hecho sobre este hidrocarburo.

Published: January 2022

During the biomass densification can be recognized various technological variables and also material parameters which significantly influences the final solid biofuels (pellets, briquettes) quality. In this paper, we will present the research findings concerning relationships between technological and material variables during densification of cocoa husks. Cocoa husks, as an unused raw feedstock after chocolate production, is a typical product of food factory. The main goal of presented experimental research is to determine the effect of compression pressure and material particle size on final biofuels quality, and thus investigate the possibilities for densification of cocoa husks. Experimental research described in this paper was realized by single-axis densification, which was represented by experimental pressing stand. The effect of mentioned investigated variables on the final pellets density was determined. Mutual interactions of these variables on final pellets quality are showing the importance of mentioned variables during the densification process. Impact of raw material particle size on final biofuels quality was also proven by experimental research on semi-production pelleting plant. Research findings dealing with pelleting and briquetting possibilities are included.

The principal object of this study is blast-induced groundvibration (PPV), which is one of the dangerous side effects of blastingoperations in an open-pit mine. In this study, nine artificial neuralnetworks (ANN) models were developed to predict blast-induced PPV inNui Beo open-pit coal mine, Vietnam. Multiple linear regression and theUnited States Bureau of Mines (USBM) empirical techniques are alsoconducted to compare with nine developed ANN models. 136 blastingoperations were recorded in many years used for this study with 85% ofthe whole datasets (116 blasting events) was used for training and the rest15% of the datasets (20 blasting events) for testing. Root Mean SquareError (RMSE), Determination Coefficient (R2), and Mean Absolute Error(MAE) are used to compare and evaluate the performance of the models.The results revealed that ANN technique is more superior to othertechniques for estimating blast-induced PPV. Of the nine developed ANNmodels, the ANN 7-10-8-5-1 model with three hidden layers (ten neuronsin the first hidden layer, eight neurons in the second layers, and fiveneurons in the third hidden layer) provides the most outstandingperformance with an RMSE of 1.061, R2 of 0.980, and MAE of 0.717 ontesting datasets. Based on the obtained results, ANN technique should beapplied in preliminary engineering for estimating blast-induced PPV inopen-pit mine.
Application of uncertainty analysis based on Monte Carlo (MC) simulation for life cycle inventory (LCI)
Authors: Sala Dariusz , Bieda Bogusław
Published: January 2022

The use of Monte Carlo (MC) simulation was presented inorder to assess uncertainty in life cycle inventory (LCI) studies. The MCmethod is finded as an important tool in environmental science and can beconsidered the most effective quantification approach for uncertainties.Uncertainty of data can be expressed through a definition of probabilitydistribution of that data (e.g. through standard deviation or variance). Thepresented case in this study is based on the example of the emission ofSO2, generated during energy production in Integrated Steel Power Plant(ISPP) in Kraków, Poland. MC simulation using software Crystal Ball®(CB), software, associated with Microsoft® Excel, was used for theuncertainties analysis. The MC approach for assessing parameteruncertainty is described. Analysed parameter (SO2,) performed in MCsimulation were assigned with log-normal distribution. Finally, the resultsobtained using MC simulation, after 10,000 runs, more reliable than thedeterministic approach, is presented in form of the frequency charts andsummary statistics. Thanks to uncertainty analysis, a final result is obtainedin the form of value range. The results of this study will encourage otherresearchers to consider this approach in their projects, and the results ofthis study will encourage other LCA researchers to consider the uncertaintyin their projects and bring closer to industrial application.

This paper examines the preconditions for collective action in the context of Water User Associations (WUAs) in Tajikistan. The paper uses qualitative case studies of five WUAs from three cotton-producing districts of Khatlon region in Tajikistan. Findings suggest that the ability of WUAs to generate collective action for the benefit of the rural community depends on factors internal and external to WUAs. The WUAs in our study tended to exhibit top-down organizational forms which might not bode well for their sustainability. WUAs were set up by donors in a setting where large, collectivized farms and vestiges of command agriculture persist alongside small individual farms. The presence of large farms among smaller holdings makes it difficult for WUAs to distribute water equitably among its members. Local government officials tend to favor the interest of big planters over small independent farms and can exert pressure on WUAs to skew water distribution. By studying the institutional challenges facing water resource management in Tajikistan, a major natural resource challenge facing all the Central Asian economies, the paper identifies opportunities for speeding up the process of agrarian reforms currently underway in all the transition economies.
