Authors: Damajanti Neni , Ma’ruf Anwar , Nugraha Hanafi Khafid
Published: November 2021

Zeolite as an adsorbent has been widely used. Zeolite activation was carried out to increase the absorption. This study aimed to determine the characteristics of the active zeolite and apply it as an adsorbent. The activation process was carried out by adding acid and calcining at 4500C for 6 hours. Remazol Yellow FG is a dye that is widely used in the textile industry. In this study, the adsorption process was carried out on the Remazol Yellow FG solution, then analyzed the effect of changes in pH (5, 6, 7, 8, 9), contact time (30, 60, 90, 120, 150 minutes) and the concentration of Remazol Yellow FG solution ( 50, 100, 150, 200, 250 ppm) on the adsorption of Remazol Yellow FG dye. From the analysis of the sample solution of Remazol Yellow, the values of Ce and qe can be calculated. These values were then used to calculate KL and KF in the Langmuir adsorption isotherm and Freundlich adsorption isotherm models. From the experimental results, it could be seen that as the contact time increased, the adsorption capacity would be greater. However, when the zeolite was already in the saturated phase, the adsorption capacity would tend to decrease. In the Langmuir adsorption isotherm, the KL value was 0.0274 L/mg and in the Freundlich adsorption isotherm model, the KF value was 29.25 L/mg. Remazol Yellow FG adsorption tended to follow the Langmuir adsorption isotherm model with an R2 value of 0.998.

With the aim to explore the use of tree pruning waste as replacement material in papermaking, a study was conducted to investigate the effect of soda pulping concentration on the tear resistance and surface morphology of the fabricated papers. By varying the sodium hydroxide concentration from 5% to 25%, tree pruning waste papers with different tear resistance and surface morphology were fabricated. The tree pruning waste papers with the optimum tear resistance (73049.68 mN) was produced when the pulping medium was prepared at 20% sodium hydroxide concentration. As confirmed by the morphology study, the pulp fibres with improved interlocking surface morphology was produced at 20% sodium hydroxide concentration. Beyond that, fibre fibrillation had took place and exerted negative impact on the tear resistance of the papers. The present study confirms the use of tree pruning waste as an alternative in papermaking. Nonetheless, the soda pulping concentration must be properly regulated in order to maximize the performance of the fabricated paper products.

Globalizing Higher Education and its Impact on Indian Expat Students (A Case Study of Indian Expat Students Living in UAE)
Authors: Ansari Ebrahim
Published: November 2021

Education is the backbone of a progressive society as it is clear from the statement of Thomas Jefferson “educate the masses” as he believed that in order to make changes in a society, the whole masses should be educated. The term ‘education’ is a popular and common term used by everybody but understood by very few in its right perspective. In educational text books it is defined as a purposive, conscious or unconscious, psychological, sociological, scientific and philosophical process that brings about development of the individual to fullest extent and also the maximum development of society in such a way that both enjoy happiness and prosperity. Despite the existence of infrastructural facilities, economic status and availability of various educational courses, the attitude towards higher education and learning is not found to be positive among the Indian expat students.

The ultimate objective of this study is to find out the factors that influence the attitude of the students towards higher education and recommend sufficient measures to improve it.

Authors: Drumil Newaskar  , Shubham Gandhi  , Preet Aligave
Published: November 2021

Additive manufacturing is a revolutionary technology because of its ability to creates objects by adding material layer by layer rather than removing material from a block or by moulding procedure. Additive manufacturing has been around for more than three decades but still, traditional manufacturing is the dominant method for manufacturing. COVID-19 pandemic has been a torment globally and has brought distress and instability to the global economy. Due to this, the manufacturing sectors are badly affected. In this time of crisis, additive manufacturing has played a major role. This paper discusses the upsurge of Additive manufacturing due global COVID-19 pandemic and its worldwide impact on supply chain management.
Khap Panchayat: Retrieving ‘Honour’ through Violence
Authors: Yamin Khan
Published: November 2021

As the custodians of honour, Khap Panchayats are self-proclaimed tribunals with full validity and authority among the segments of their caste. These Panchayats are not real courts and do not have a constitutional basis. Under this unconstitutional system, all people of a village huddle around a Chabutara in order to make rapid, unilateral, and incontestable decisions on a variety of problems such as social transgression, marriage, offences, property rights, or situations endangering the village's tranquillity. It is concerning to notice that, in an era where individuals communicate via 3G technology, Indian civilization has regressed to the Dark Age. In today's culture, when legal standards and constitutional authority rule society, organisations like the Khap Panchayat obstruct progress and good government. The residents of the particular territory or community in which 'Khap' exists praise the dictates of Khap Panchayat; this is the most significant hurdle to Khap Panchayat's elimination. This study attempts to answer the question, "Why do Khaps still exist in India?" What is Khap's source of strength? It provides a thorough examination of the problem and attempts to propose a solution.
Wheat Responses, Defence Mechanisms and Tolerance to Drought Stress: A Review Article
Authors: Savyata Kandel
Published: November 2021

Wheat (Triticum aestivum L.) is one of the major basic stable crops grown worldwide, however, it is sensitive to environmental stresses like drought. With climate change, drought stress is becoming an increasingly severe constraint on wheat production which affects the plant growth and development, physiological functions, grain formation, grain quality and ultimately the yield. Various responses including biochemical, physiological, morphological, and molecular adaptations are shown by plants to survive in the drought stress condition. Drought escape, avoidance and tolerance are important coping mechanisms of wheat plant under drought environment. Several mechanisms such as accumulation of ABA, osmotic adjustment, and induction of dehydrins may confer drought tolerance by maintaining the high tissue water potential. As the root structure and root biomass define the pattern of water extraction from the soil, enhanced root and suppressed shoot growth resulting in higher root: shoot ratio facilitated plants to drought tolerance. The development of drought tolerance varieties becomes an important due to the uneven distribution of rainfall and water shortage. Some growth stage-specific physio-morphological traits are fundamental targets to breed drought-tolerant wheat varieties. Mutation breeding, molecular breeding, genome engineering techniques including gene pyramiding, gene stacking, and transgenics are employed to breed wheat for tolerance to abiotic stresses including drought. Omics decode the entire genome to have better understanding of plant molecular responses that will provide precise strategies for crop improvement. This paper discusses the wheat plant’s responses to drought stress, their defense mechanisms and modern techniques for the development of drought tolerant wheat varieties.

Authors: Nishtha Chaturvedi  , Chhaya Chaturvedi
Published: November 2021

Covid 19 is a pandemic disease came in existence in 2019. It is also called as the Human Corona Virus disease which is caused by SARS-CoV-2. Currently more than 215 countries around the world are being reported to be the sufferers of this disease. When this disease came into existence the diagnosis of the disease became a major task for the scientists and doctors across the world. A method known as RT PCR (Reverse Transcriptase Polymerase Chain Reaction) was applied during that crucial period to detect this disease. Among other diagnostic tools, CRISPER (Clustered Regularly Interspaced Short Palindromic Repeats) Cas system is being investigated for rapid and specific diagnosis of COVID-19. CRISPER-Cas technology is a highly flexible RNA guided endonuclease (RGEN) based nucleic acid editing tool that has transformed the field of genomics, gene editing, gene therapy and genome imaging. As compared to RT PCR which gives the result of diagnosis in 4-8 hours, the CRISPER Cas based method diagnose it within an hour. So, this technique came out to be a very appropriate and less time-consuming method for detection of the disease. This article is focuses on explaining the potential use of CRISPER Cas9 based approaches for the development of accurate and rapid diagnostic technique and antiviral therapy for detecting and limiting the spread of COVID-19. As this technique is new and advanced so can also be used for various other future applications too.

Associations between dimensions of Mental Health Literacy and adolescent help-seeking intentions
Authors: Goodfellow Claire , Macintyre Anna , Knifton Lee , Sosu Edward
Published: November 2021

Background: Adolescence is a critical period for the development of mental health problems. However low mental health literacy (MHL) may impede help-seeking for these problems. Although MHL is a multidimensional construct and adolescent help-seeking can be through formal and informal means, little is known about how dimensions of MHL influence these help-seeking intentions. This study examines associations between dimensions of MHL and formal and informal help-seeking intentions among adolescents. It also investigates whether informal help-seeking mediates the association between dimensions of MHL and formal help-seeking, and whether these associations are moderated by gender. Methods: A cross-sectional survey including measures of MHL, and help-seeking intentions was distributed to participants in ten schools (12-18 years) across Scotland (n = 734). Data were analysed using Confirmatory Factor Analyses (CFA) and Structural Equation Modelling (SEM). Results: CFA identified two distinct dimensions of MHL: ability to identify a mental health problem, and knowledge of treatment efficacy. Only knowledge of treatment efficacy was associated with increased intention to seek formal and informal help. Ability to identify a mental health problem was negatively associated with both forms of help-seeking intention. Informal help-seeking mediated the association between both forms of MHL and formal help-seeking. Gender did not moderate associations between MHL and help-seeking. Conclusions: Distinct dimensions of MHL have disparate associations with adolescent help-seeking intention. Care should be taken when providing MHL interventions to ensure that adaptive forms of MHL are equally promoted. Future research should investigate possible mechanisms by which discrete forms of MHL influence adolescent help-seeking.

Lateral force-displacement response of buried pipes in slopes
Authors: Katebi Mohammad , Wijewickreme Dharma , Maghoul Pooneh , Roy Kshama
Published: November 2021

A series of full-scale experiments were conducted to estimate lateral soil constraints on the pipes buried in dense sandy slopes at different burial depths. The experimental data indicated that the soil force on the pipe increases with increasing the slope grade and burial depth ratio. The lateral soil force versus relative pipe displacement response observed from the experiments is presented and compared to those arising from level ground conditions. The study was extended to larger burial depth ratios by simulating pipes under sloping ground conditions using a numerical (finite element) model that was initially calibrated using the results from physical modelling. The findings from the study in terms of the variation of peak lateral soil restraint as a function of the slope grade and burial depth ratio are presented for consideration in pipeline design.
Questionable Research Practices in Single-Case Experimental Designs: Examples and Possible Solutions
Authors: Tincani Matt , Travers Jason C
Published: November 2021

Questionable research practices (QRPs) are a variety of research choices that introduce bias into the body of scientific literature. Researchers have documented widespread presence of QRPs across disciplines and promoted practices aimed at preventing them. More recently, Single-Case Experimental Design (SCED) researchers have explored how QRPs could manifest in SCED research. In the chapter, we describe QRPs in participant selection, independent variable selection, procedural fidelity documentation, graphical depictions of behavior, and effect size measures and statistics. We also discuss QRPs in relation to the file drawer effect, publication bias, and meta-analyses of SCED research. We provide recommendations for researchers and the research community to promote practices for preventing QRPs in SCED.
Examining Schizotypal Personality Scales Within and Across Interpersonal Circumplex Surfaces
Authors: Asan A. Esin , Pincus Aaron L.
Published: November 2021

Differing perspectives on the operationalization of schizotypal personality pathology (STPP) have led to numerous multidimensional assessment measures. The current study applied the interpersonal construct validation approach to self-report data from 856 undergraduate students to formally examine the interpersonal content, similarities, and differences of the subscales of four measures of STPP within and across two interpersonal circumplex surfaces using a bootstrapping methodology for computing confidence intervals around circumplex structural summary method parameters. Results suggested that negative-like expressions of STPP are prototypically and distinctively interpersonal constructs associated with cold and socially avoidant interpersonal problems and hypersensitivity to others’ warmth and affection. Positive-like expressions of STPP as assessed by two out of four measures were prototypically and distinctively interpersonal constructs associated with vindictiveness. Across four measures, there was notable overlap in interpersonal correlates among related subscales, suggesting convergent validity. However, subscales containing social anxiety content were associated with more submissive (i.e., socially avoidant) interpersonal problems than subscales without social anxiety content.

The author points out that the Council Decision 2020/2053 requires ratification in accordance with the law of Member States. In the case of Poland it should be the procedure specified in Article 89 para. 1 of the Constitution, therefore requiring a prior consent granted in a statute. This mode has to be chosen to avoid imposing a significant financial burden on the state and because of earlier practice regarding the ratification of such decisions. The author excludes the possibility of the so called great ratification (Article 90 of the Constitution, majority of 2/3 votes in the Sejm), because the decision does not grant any new powers to the Union.

Smartphones and Exploitation in the Age of Digital Capitalism: Ordinary Aspects of the Transformation of Everyday Life
Authors: Canpolat Emre
Published: November 2021

This study examines the transformation of everyday life through smartphones, focusing on the daily experiences of smartphone users in Turkey. With their multimedia features, smartphones (defined as a “melting pot” from the technological perspective or polymedia and metamedia in a broader sense) take an important place in users’ everyday lives. As these features and the services accessible through smartphones are offered in commodity form, they inevitably result in the exploitation of users’ labour, the commodification of user data, the shifting of paid work into ‘leisure time’, and finally the transformation of everyday life through smartphones. The main argument of this study is that, under these social conditions, smartphones, referred to as “a melting pot” from the technological perspective, turn into a melting pot of exploitation, and their users experience these interactions not as direct economic relations but as routine social relations.

Authors: Lytvynchuk Anna
Published: November 2021

At present, the state of the economy of the agricultural sector in many countries of the world, including in the countries of the European Union (EU), inherent in developed industry, has led to the transition to a new environmentally oriented agricultural policy. An important role is assigned to state support of agricultural producers, through subsidies, preferential credit policy, and in some countries, the complete abolition of taxation of entrepreneurial activity in rural areas, which confirms the relevance and national economic significance of the article. In domestic agroeconomic science and practice, there is no scientific concept of state participation in the process of bringing the agricultural sector out of the crisis. Research objectives – consider the development policy of the agricultural sector of the EU countries; study the level of state support for agricultural producers. The purpose of the work is to consider the degree of development of the agricultural policy of the EU countries in the context of ensuring food security. The methods and methodology of the research were general scientific, particular methods of cognition, including the historical and logical, the method of observation and comparison. Shows the main approaches to state regulation of the development of the agro-industrial sector at the level of the European Union as a whole and in the context of member countries; characteristic features and principles that determine the success and integrity of a unified agricultural policy; factors contributing to the productivity of agricultural land; agro-ecological requirements restricting the import of genetically modified products; the main tasks in the development of a new policy of the agrarian sector of the economy; priority directions of regulation of measures to support agricultural producers, integrated development of rural areas, increasing the competitiveness of the EU agricultural sector. The practical significance of the work lies in the fact that this study will allow the state bodies of Belarus to better understand how it is necessary to form an agricultural policy in the context of ensuring food security.

Authors: Shalupayeva Natallia
Published: November 2021

Nowadays, economic diversification remains a key challenge for most developing countries. The world trading system is developing from universal liberalization to increased protectionism which imposes additional difficulties in countries’ exports development and puts export diversification at the heart of a strategy for economic diversification. China's foreign trade is also in a critical period of rapid development and transformation at present. China is building a new pattern of integration into the world economic system, but its economic transformation is not smooth and faces problems. Taking into account China’s high reliance on exports, one of the most important threat to China’s economic development – the susceptibility to fluctuations in global economy – is largely due to a low level of Chinese exports diversification. In order to achieve a more sustainable long-term economic growth and hedge against the impact of external shocks China needs to diversify its exports markets, range of exported products and trade methods. Purpose. The purpose of the article is the research of practical aspects of exports diversification in China, identification of features and problems of China’s exports product and market diversification, diversification of trade methods and high-tech products exports diversification. Methodology. The methodological basis of the study is presented by the theories of foreign trade and industrial policy, as well as by the researches realized in the field of exports diversification.

Le choc de la nouvelle : perspective psycho-oncologique sur la communication médecin–malade
Authors: Dunand A. , Saraga M.
Published: November 2021

Les communications des médecins à leurs patients sont souvent rapportées en consultation psychologique lorsqu’elles ont un impact fort. Trois cas cliniques illustrent le fait que cette communication est complexe, dépend des acteurs en présence et de la situation, et qu’une approche standardisée est difficilement applicable. Le rôle du psychologue envers le patient est de l’aider à intégrer l’effet de cette communication. Envers le médecin, il est de lui permettre de communiquer de façon nuancée avec ses patients.
Myanmar: Interim Governance Arrangements: Comparative Principles and Practice
Authors: Bell Christine
Published: November 2021

Comparative Principles and Practice The background to this brief is the context of the military coup in Myanmar in February 2021, and the declaration of a state of emergency by the military, which has effectively set aside the 2008 Constitution and the elections held under it. The coup has been rejected by the international community as illegitimate and has generated a strong civil disobedience and protest movement, and those elected in November 2020 have formed interim institutions aiming to move towards a democratic order. The military have also recently re-termed their post-coup regime as a ‘provisional government’. This brief sets out some comparative principles and practices of interim governance arrangements, which are a device often used to move on from crisis. The brief does not purport to offer direct advice as to the way forward in Myanmar, as that will be for all the relevant stakeholders in the country to agree. Rather, it seeks to support deliberation, and some questions for this purpose are provided at the end of the brief.

This study aims to determine whether there is an influence on the implementation of PBL through a scientific approach that provides a media card for high school students' chemistry learning outcomes. To achieve this goal, quasi-experimental research was conducted using two classes, namely the experimental class and the control class. Data obtained using a validated test instrument in the form of pretest and posttest. The results showed that (1). There was an increase in chemistry learning outcomes from the average pretest 27.2 to 63.95 and 72.5 in the two classes of experiment I and experiment II, respectively. (2). Student learning outcomes that are taught with the Problem Based Learning model and the scientific approach provides higher paired cards than using textbook as a media.
Evaluation of the correlation between the Istanbul Low Back Pain Disability Index, Back Pain Functional Scale and other back pain disability scales in Turkish patients with low back pain
Authors: Karadağ Ahmet , Canbaş Muhammed
Published: November 2021

BACKGROUND: Low back pain is an important health problem that may cause functional loss. Several back pain disability scales have been developed in different languages. OBJECTIVE: The present study evaluates the correlation between the Istanbul Low Back Pain Disability Index (ILBPDI) the Back Pain Functional Scale (BPFS) and other back pain disability scales in patients with mechanical low back pain. METHODS: Included in the study were 105 patients who presented to our outpatient clinics and who were diagnosed with mechanical low back pain. The ILBPDI, BPFS, Quebec back pain disability scale (QBPDS) and Oswestry low back pain disability questionnaire (ODI) were administered to all participants, and Visual analogue scale (VAS) scores were recorded. RESULTS: A strongly negative correlation was identified between ILBPDI and BPFS (p< 0.05), and a strongly positive correlation was noted between ILBPDI and QBPDS, ODI and VAS. CONCLUSION: A strong correlation exists between ILBPDI and BPFS, and a further strong correlation between ILBPDI ODI and QBPDS. These questionnaires can be used interchangeably to evaluate disability associated with chronic mechanical low back pain.

Published: November 2021

The process of mainframe machines managing and administration requires not only specialized expert knowledge based on many years of experience but also on appropriate tools provided by a machine performance management system, e.g. the Resource Measurement Facility (RMF). The aim of this paper is to show some preliminary results of Z-RAYS system construction that is built basing on machine learning (ML) techniques. It allows automatic detection of anomalies and generation of early warnings about some errors that can appear in the mainframe to support mainframe management process. Presented results are based on extensive simulations that were done basing on the IBM emulator. We focus on determining the degree of the metrics variability, the degree of the data repeatability in metrics, some approaches in metrics anomaly detection and solutions for event correlation detection in metrics.

Published: November 2021

Concerning the expansion of the coronavirus in the world, the search for the development of solutions related to the control and mitigation of the pandemic situation became constant. The paper addresses an analysis of localities for the installation of field hospitals, highly requested as a point of treatment for COVID-19. In this scenario, a framework based on the P-median approach and mathematical programming is proposed, enabling an optimization model as an analysis format for the problematic situation. To support the implementation of the model, a computational tool for data processing was developed, integrating an optimization model to the geographical evaluation, exploring in the analysis numerical and graphical resources. As a validation of the study, a case study in the city of Rio de Janeiro – Brazil is presented, analyzing 162 neighborhoods and determining seven favorable localities for the installation of field hospitals.

Personnel selection is increasingly proving to be an essential factor for the success of organizations. These issues almost universally involve multiple conflicting objectives, uncertainties, costs and benefits in the decision-making process. In this context, due to the characteristics of human resources problems, composed of several subjective evaluation criteria, such problems can be solved by applying Multiple Criteria Decision Aid (MCDA) methods. This paper aims to present a literature review on the main applications of MCDA in the personnel selection area, considering the tactical, operational and strategic spheres. The methodology includes a bibliometric study and a literature review of documents from the Scopus database. We identified the document type, year of publication, affiliation, authors, author’s H-index, the field of knowledge, country and keyword clusters. The literature review allowed us to verify that the Fuzzy Logic is the most applied methodology in personnel selection problems with MCDA, due to its capacity to handle vague, imprecise and subjective data.

Published: November 2021

COVID-19 is a pandemic outbreak for each country worldwide. Each government needs to monitor every citizen and the COVID-19 test becomes an essential evidence for people who are travelling. This gives rise to the necessity of disruptive technologies such as Blockchain. In this paper, we provide an overview of the Hyperledger and Ethereum platforms and present how healthcare organizations can control and monitor digital health test certificates with citizens or other stakeholders. We also present a smart contract structure and implementation for COVID-19 test certificates in both blockchain platforms.

This manuscript focuses on the Belt and Road Initiative (BRI) of China, whereby the focus is on the engagement of big data analytics to comprehend logistics exertion. China is the trendsetter for revolutionary practices in trade, logistics, and technology. The recent progress the nation is thriving is on ‘One Belt One Road’ project whereby 65 countries are involved. It aims to connect continents and circulate smooth trade between them. This paper addresses the role of the database to identify the inter-model logistics in BRI. The merits of this project in the perspective of economic growth are measured through a quantitative study with 112 samples. Goal-setting theory is used to construct a conceptual framework for the research. Multivariate analysis is executed with SmartPLS 3.3.3 followed by an in-depth structural equation modeling. Normal distribution of data was given importance as in statistics the real-value of random variables whose distributions are not known, thus Gaussian distribution of data was used. Out of 6 Hypotheses, it is noted that five are significantly positive. Hypothesis testing is concluded based on p-value and t-statistics. The outcome of research suggests that big-data analytics is a major contributor in determining the significant model on logistics in Belt and Road Initiative.
