Hydrogeology of the Balaesang Tanjung Region, Donggala District, Central Sulawesi, Indonesia
Authors: Abdullah Ahmad Imam , Uno I. , Marhum F. A. , Botjing M. U. , Abdullah  , Sandra
Published: December 2022

Balaesang Tanjung in Donggala Regency is a peninsula surrounded by the sea. It is considered to have limited groundwater to be used as a source of clean water. This preliminary hydrogeological study aims to estimate the groundwater potential zone in the area. The main feature based on the lowest topography and gentle slope. It is occupied by the Molasse Formation, where limestone and other deposits are characteristic of a porous lithology, which most likely allows infiltration processes to occur in this area. Of course, the presence of discontinuities in limestones can serve as secondary porosity for storing fluids. So that the delineation of groundwater recharge follows the distribution of the Molasse Formation and the morphology of the plains. From these results, we recommend that the western Balaesang Tanjung area can act as a low to moderate productive aquifer, where the flow can flow through fissures and fissures.
Is an Explanation a Reason?
Authors: Rastall Paul
Published: December 2022

Are reasons and explanations the same things? The paper considers explanations and reasons in a range of contexts and identifies similarities and differences in them. It is suggested that, while the two notions are linked in reasoning, there is a difference of focus, with reasons being concerned with more general principles and explanations being concerned with the application of principles to specific instances. However, in a “model-dependent reality”, there can be explanations, but not ultimate reasons.
Mapping the Motif of the Wandering Jew in Salim Kumar’s Karutha Joothan
Authors: John Jeslin Mery , Jacob Asha Susan
Published: December 2022

The motif of the Wandering Jew is an archaic motif whose conventional elements can function within widespread narrative contexts. Formally the motif might operate in the same manner as do other motifs: as just another component of the narrative structure. But because of the comprehensive nature of its features, this motif is able to deliver its essential message of human suffering even as it migrates through diverse cultural environments, as the interaction of its axiological elements with their newly acquired social and cultural contexts has the capacity to appear seamless and unlaboured. Salim Kumar’s Malayalam film Karutha Joothan (2017) is a case in point. The work employs this motif remarkably well in what is an uncharted cultural context: the dwindling community of Black Jews in Kerala. Along with articulating the distress of a marginalised community, the film memorialises a significant historical era. This paper examines the ways in which the film’s protagonist comes to represent the prototypical lonely wanderer of the generic myth.
Visual Disability and the Pursuit of Normality in Preeti Monga’s Biographical Novel The Other Senses
Authors: Kowsalya G. , Dhanabal C.
Published: December 2022

For Ancient Greeks, beauty was a characteristic of individuals and actions that they considered to be morally good. Greek statuary and art in general project beauty based on the assumption that outward appearance reflects personal virtues (Tytler, 1982, p. 36). Pythagoreans, for example, held that ugliness expressed confusion and turmoil, and that beauty was a material expression of universal truth. In more modern times, and in many ways envisaging today’s materialistic societies, Kant expresses a certain perplexity that beauty is perceived primarily as a pleasurable response to exterior form (2000, p. 111). In this sense contemporary culture, with the increasing visual refinements of its graphic products and virtual reality, has set new metrics for defining the value of beauty. Our televisions, for example, broadcast images of heroes who are physically beautiful while being morally suspect and socially abrasive. The unstable value of beauty is reflected in literature. In Indian literature disability has been represented, but these representations have lacked significant scholarly diagnostic treatment. The Disability Rights Movement has recently begun to change this situation. This paper strives to examine a disabled individual’s struggle for integration through Preeti Monga’s autobiography The Other Senses. It also analyses how the disabled create subjective normality and the process by which they attain it. By tracing the roles of sexuality, dependency, and interpersonal relationships in the lived experience of Preeti Monga, this research aims to reveal the significance of the quest for normality in shaping personal identity.
Cultural Expectations and Gendered Roles: Identity Formations in Jhumpa Lahiri’s The Lowland
Authors: Bhattacharya Damini
Published: December 2022

Individual identities are not only a summation of one’s unique choices and experiences, but are also influenced by the culture, society and politics of the place in which individuals feel a sense of belonging or of the place where, on the contrary, they experience a disruption of the self. For a diasporic subject, the experiences in the home country and the country to which they’ve relocated create a binary identitary self, one that develops in the space that opens between the familiar feelings of belonging and the newfound sense of alienation. Within that space the immigrant resides in a transnational and global context that does not fully incorporate either place. Gauri, the protagonist in Jhumpa Lahiri’s The Lowland, attempts to forsake her Indianness, but her new experiences and her determination to do away with the cultural signifiers of her traditional Indian upbringing provoke a synthesis, one that integrates fragments of the new, envisioned identity with remnants of a past identity that is very much alive in her unconscious. By analysing these fragments and remnants, the paper identifies patriarchy, sexuality, sexism, racism and conflicting ideas of motherhood and family as factors being negotiated by the protagonist as she contrives frames of reference for her new identity.
Computational Modeling of Textured Enzyme Immobilizing Scaffolds in a Packed Bed Reactor
Authors: Rojnuckarin Andrew , Baker Hailey , Foster David
Published: December 2022

Understanding and analyzing heterogeneous reactions in packed bed
reactors is important in many applications. Here we present a
computational model to investigate the impact of surface texturing on
enzyme immobilizing scaffolds in a packed bed environment. It was
hypothesized that the implementation of surface texturing would increase
the overall reactive surface area of the bed and thus improve reactor
efficiency. The model utilizes computational fluid dynamics (CFD) to
solve the transport, multi-component flow, and reaction kinetic
equations. A stochastic algorithm for random packing of sphere-like
particles was also implemented to mimic the random packing that exists
in a typical packed bed. This model analyzes the many coupled forms of
transport and reaction kinetics that exist in a packed bed reactor with
the goal of improved resolution and understanding of the system. The
impact of form drag as it relates to scaffold geometry on outlet product
concentration is included.
Unsteady three--dimensional oscillatory Jeffrey fluid flow over an infinite horizontal plate with periodic suction
Authors: Rana Muhammad , Zafar Mehwish
Published: December 2022

Experimental and theoretical studies have established that the
transition to turbulent from laminar flow (promoting the drag
coefficient) may be prevented/delayed by the fluid suction from the
boundary layer to the plate. Due to such an active role of laminar flow
control in plummeting drag ensuing improvement in the power of vehicle
by a considerable amount, this work aims to analyze periodic suction
impact on 3-dimensional unsteady oscillatory flow of Jeffery fluid
flowing laminarly along an infinite porous plate lying horizontally with
transverse sinusoidal suction. The free stream velocity swings to and
fro about a constant mean in time. The flow becomes 3-dimensional
because of transverse direction of the periodic suction velocity.
Approximate solutions are attained for velocity components, shear
stresses and pressure. On these physical quantities the impact of
dimensionless parameters budding in the problem under consideration are
graphically visualized and analytically conferred. The x-component of
velocity is noted to be increasing for rising values of Re which causes
the decay in boundary layer thickness. Further, the velocity component u
is found to be reducing with increasing values of β because of the fluid
thickening. It is also observed that an enhancement in Re causes to
reduce the pressure. On the contrary, α causes to rise the pressure. The
shear stress along the z-direction is augmented by increasing the
suction parameter. The shear stress in the z-direction also increases by
increasing the elastic parameter because of the thickening of the fluid.
The results of present study agree to published work in limiting sense.
This study is advantageous in manufacturing and designing LFCS (laminar
flow control system) to improve the vehicle power necessity.

Authors: Rony Pritam Karmakar , Uddin Md. Misbah , Amin Gazi Md. Riasat
Published: December 2022

Surma is a principal distributary of the Barak River, which is the main
source of fresh water in South-Eastern region like Sylhet, Sunamganj of
Bangladesh Bengal. Every year huge amount of sediment loads are coming
from upstream which are settling down on Surma river bed, hindering the
safe passage of flow which contributes to the change in hydrodynamic and
morphological characteristics of the river. Recently a dredging has been
done in Sunamganj area to increase the navigability of the river in that
area. In this study work, the hydrodynamic study of the river Surma has
been investigated to check the impact of dredging with the help of
HEC-RAS. For these flood frequency analysis has been done for ( 5, 10,
25, 50, 100) years return period and comparison of water level, velocity
and discharge has been done before and after dredging. Before dredging
the water level, flow path was very high, velocity, discharge was low
but after dredging water level, flow path. Discharge also decreases
after dredging in the 6 stations which are located in the dredged area,
the values are 1375.41 m /s, 1374.31 m

Identification and stakeholder responsibility mapping of contractual risk factors in oil and gas sector infrastructure projects using Delphi technique
Authors: Tirmizi Syed Asim Ali , Arif Farrukh
Published: December 2022

The continuing demand for energy has led to the need for developing and improving the oil and gas infrastructure through the execution of various infrastructure capital projects in many parts of the world, including Pakistan. Oil and gas companies have vast experience implementing these infrastructure projects, yet many such projects face delays and cost overruns. This failure to meet project targets may be attributable to the lack of identifying and addressing the risks at the pre-execution stage in the contract documents. This study aims to identify the risks to address in the contract documentation developed for the infrastructure projects and allocate each factor to a particular stakeholder (Client, design consultant, legal consultant, and bidders) in Pakistan. Risks were identified through literature review and were validated using the Delphi technique applied through surveys. Twenty-four survey respondents were selected based on their qualifications and experience in Pakistan’s Oil and Gas sector. In the first round of the Delphi survey, the level of agreement authenticates the risks applicable to Pakistan's Oil and Gas sector. The level of agreement was reaffirmed in round two of the Delphi survey. It also included a check for stability of responses between rounds using the McNemar test. Results confirmed that sixty-one risk factors are the contractual risk for evaluation when developing contracts for Oil and Gas infrastructure projects in Pakistan.
Predicting mental illness at workplace using machine learning
Authors: Khan Taha , Dougherty Mark
Published: December 2022

Mental illness (MI) is a leading cause of workplace absenteeism that often goes unrecognized and untreated. This paper presents a machine learning algorithm for predicting MI at workplace. The dataset consisted of responses from 1259 subjects collected through an online survey using a self-assessed questionnaire on the workplace environment. The responses were used as features for training a support vector machine to predict MI. Statistical analysis using the Guttmann correlation and the analysis of variance was done to determine feature significance. Results using 10-fold cross-validation showed that the model predicted MI with good accuracy. Findings support the feasibility of this approach for MI monitoring at the workplace as it offers an advantage over other technologies e.g., MRI scans, and EEG analysis, previously developed for the objective assessment of MI.

Authors: Kutlu İzzettin , Bekar İrem
Published: December 2022

The global threats that arise due to the changing needs as a result of the advancement of technology cause the rapid depletion of natural resources. This situation necessitates studies to protect resources and reduce energy consumption. Recent studies have particularly emphasized the concept of “sustainability”. Today, as a result of the emergence of sustainability in buildings, certification systems have been developed in which the features of buildings are revealed. In this study, 4 certificate systems frequently used in different countries were discussed. First of all, these systems were examined, and their current data were revealed. The study aims to reveal the sustainability of a historical building located in an important historical city in Turkey according to criteria of the determined certification system. For this aim, the Old Government House in Mardin was discussed as a study area. The historical features of the building and plan features were included in the study area. In the findings of the study, the features of the historical building were determined according to the criteria of certification systems. In the evaluation of the features revealed, suggestions were made especially for the use of energy and water. At this point, to use simple renewable energy sources and systems will support the efficient and recycling of water in the building. This situation will contribute to the sustainable use of the faculty to a great extent. As a result, the sustainable preservation of historical buildings can be achieved in the long term by producing its own energy and using recyclable systems.
Numerical Simulation of The Spectroscopic Properties of The Laser Dye for Low Concentrations
Authors: Dagher Hala Fakher
Published: January 2023

In the current study, a mathematical model using the MATLAB program was studied depending on the logistic power peak function to simulate the change in the absorbance with the different values of the concentrations of Rhodamine B. There are five parameters that have been applied to the concentration values of this laser dye that are proposed by the logistic power peak function of the seventh degree. To measure the absorption measurements, a range of concentrations from 4.7x10-7 to 3.76x10-6 M was prepared from Rhodamine B and dissolved in deionized water with a peak absorption at 556 nm. A JASCO V-630 spectrophotometer was used to record the spectra of the dye. The intensity is detected using a silicon photodiode (S1337). The results were found that the suggested function approved the relationship between the absorbance and the values of the concentrations with a significant accuracy depending on the high values of the correlation coefficients between the approximated original data which were determined more than 99.2%. The advantages of this function represent by providing parameters, which are used to describe the mathematical processes with high-resolution property profiles.

MATERIAL PROTESTS
Authors: Blanco Esmoris Maria Florencia , Ohanian María Jazmín
Published: December 2022

This article traces and exposes the material dimension of contemporary protests. In this piece, we consider protest as a particular type of human communication that gains intelligibility in specific social situations that are embodied in objects. This has led us to (re)think (about) the dialogue which exists between anthropology and communication in light of the role of material culture. We read and review these experiences from epistemological and theoretical frameworks of protest studies in Argentina and reconstruct social situations arising from our joint work developed at the research group Cosas Cotidianas (CoCo), which we co-coordinate, dedicated to analysing, from an ethnographic perspective, how objects ‘participate’ in social life. Our paper is structured into 3 parts. Firstly, an analysis of anthropology and communication is undertaken followed by protest(s) as social situations and finally, understanding protest through objects. We present how pots (in Spanish cacerolas) in Latin America, umbrellas in Hong Kong and waistcoats in Paris (France) appear as objects of protest in countries of the global south and north. The ‘cultural biography of things’ is proposed as a conceptual framework for our analysis
WILD BORDER OF POLITICS
Authors: Blavascunas Eunice , Cope Benjamin
Published: December 2022

The challenge of the politics of the Anthropocene is how to respond to the protests of nature: how to elaborate modes of thought, collective action and social institutions through which non-human agents can be integrated into political communities, even as non-humans exceed our understanding and remain a subject of difference. This paper looks at how the contested borderland forest, Białowieża, at the Polish-Belarusian border helps us think across protest culture during post-socialism. We examine the Białowieża forest as a site of, participant in and provoker of a series of protests: those against national park expansion, against logging, in support of bark beetle rewilding, of far right radical movements and for or against Middle Eastern and African asylum seekers crossing through the forest since EU sanctions were imposed on Belarus in 2021. We do so in order to suggest that these protests should be read as a continuum that enables reflection into why this forest is a key site of protest; that exploring them as a continuum reveals something about an emergent ecology of protest; and that this exploration offers an insight into what is at stake if we see the forest itself as protesting.

Authors: CASAGRANDE GUILHERME , Gonçalves Teixeira Fábio , Freitas de Oliveira Branca , Gadis Ribeiro Vinicius
Published: December 2022

O setor têxtil e confeccionista brasileiro está entre os cinco maiores do mundo e com grande destaque no ramo de jeanswear, este setor imponente traz benefícios econômicos e é responsável por milhares de empregos, porém é responsável por uma enorme quantidade de resíduos sólidos. São gerados, aproximadamente, cerca de 29.000 toneladas de resíduos têxteis, diariamente, apenas na cidade de São Paulo, e sua maior parte é tratada como rejeito, sendo destinados aos aterros sanitários ou incineração. Assim, há uma clara necessidade de aproveitamento destes resíduos, de forma a mitigar os impactos ambientais negativos causados por este grande setor, bem como dos resíduos pós-uso gerados pelo consumo exagerado da moda. Este trabalho pretende, através do desenvolvimento de armações de óculos de sol feitas a partir do reaproveitamento destes resíduos têxteis, questionar as relações de consumo atuais, criando uma reflexão referente às suas consequências socioambientais. A pesquisa tem como seu principal objetivo, desenvolver armações de óculos de sol que visem o reaproveitamento destes resíduos têxteis, tanto os de resíduos sólidos industriais quanto os de descarte pós consumo, servindo como base para a constituição do material que será aplicado nas armações desta coleção. Após alguns testes de formulações para o compósito, optou-se pelo desenvolvimento de um material com matriz polimérica de resina epóxi utilizando os resíduos têxteis como fibras em sua composição. Após as definições do material a ser desenvolvido, foram realizados alguns ensaios mecânicos a fim de levantar propriedades mecânicas e, assim, obter dados sobre sua caracterização. Este estudo apresenta, ainda, duas alternativas de fabricação para estas armações com o material compósito laminado e, posteriormente, a validação de uma delas através da prototipagem de armações de óculos, sendo apresentados como os resultados finais deste processo. Ao final deste artigo são apresentadas algumas considerações finais e sugestões de estudos futuros.
Cores digitais no ensino superior de design gráfico
Authors: Pereira da Silva Hugo Guilherme , Patrícia de Araújo Pereira Carla
Published: December 2022

Na era digital, o avanço tecnológico ampliou os recursos visuais e modificou a natureza do processo de design. Ao mesmo tempo, as novas técnicas demandaram novas habilidades e conhecimentos, para permitir explorar os recursos disponíveis visando à qualidade dos produtos finais. Ao sair da materialidade dos suportes analógicos e assumir formatos digitais, o design gráfico adquiriu necessidades específicas de manipulação e controle de cores. Nesse contexto, este trabalho investigou os conteúdos sobre cores digitais abordados em cursos de formação superior em design, sob a perspectiva de sua adequação às atuais necessidades de uso de ferramentas digitais. Este artigo relata uma pesquisa de natureza mista (qualitativa e quantitativa) e caráter exploratório-descritivo, realizada em duas etapas: (i) análise das matrizes curriculares e projetos pedagógicos de doze cursos de design gráfico oferecidos por instituições de ensino públicas brasileiras; e (ii) survey junto ao corpo discente, utilizando questionário eletrônico estruturado, totalizando 283 respondentes. A análise documental identificou escassez de conteúdo sobre cores digitais nos currículos. Os dados obtidos no survey sugerem insuficiência de conteúdos específicos sobre gerenciamento de cores, fechamento de arquivos, espaços de cores e calibração de monitores. Dentre os conteúdos questionados, os sistemas aditivo e subtrativo de cores apresentaram alto índice de assertividade.
