Abstract

The inhibition effect of propargyl alcohol on the acidic corrosion of mild steel in 5 per cent commercial hydrochloric acid was studied at different temperatures by mass loss measurements and polarization studies. Corrosion potential and corrosion current have been calculated in the presence and in the absence of inhibitor. The inhibitor efficiency increases with increase in concentration and it decreases with rise in temperature. The interrelationship between the surface coverage and concentration of the inhibitor was also studied. It has been found that the inhibitor obeys Temkin adsorption isotherm.

Abstract

The efficacy of octylamine as a vapour phase corrosion inhibitor in different corrosive environments for carbon steel, copper and brass, and its biocidal action, have been examined. The protection of these metals from atmospheric corrosion using VPI (octylamine)‐impregnated paper was monitored by visual observation, weight loss measurements, polarisation scans and impedance measurements. The long‐term protection given by octylamine‐impregnated paper to these metals was examined by Stevenson’s chamber test. It was found that octylamine offered more than 80 per cent protection against atmospheric corrosion for carbon steel, copper and brass.

Abstract

The chapter discusses how adolescents are moving beyond the dichotomy of biological and linguistic socialization, forming interpretive meanings at home through the reading of literature in their mother tongue, Bengali. Involving cultural relevance and non-vulnerability, the chapter conceptualizes “leisure activities” and “leisure pursuits” of reading practice of the IXth and Xth graders from both Bengali and English medium schools in Kolkata. The discussion from the theoretical construction mentions the further conceptualization of reading habits and language choice. This is where adolescents derive their agency. Adolescents from the Indian and especially from the Bengali perspective have a path of colonial discourse. From historical standpoint, the change in Bengali language and its grammar structure has influenced the acceptance of Bengali literature among adolescents in varying degrees through generations. Using mixed methods and content analysis, the chapter focuses on young teenagers’ narration on the way they maneuver curriculum and literature in their respective homes. Authors, for example, Sunil Gangopadhyay, Satyajit Ray, and Bibhutibhushan Bandyopadhyay, form the Bengali identity construction in the present time. Rabindranath Tagore’s, Sarat Chandra Chattopadhyay’s and Bankim Chandra Chatterjee’s works are always prevalent in the Bengali language syllabus. These are considered the foundational modern literary figures of pre-independent India. These are taught from a nationalist and gender discourse perspective. The adolescents in this chapter also read those at a minimum level at home and attempt to juggle the difficult vocabulary involved. The simple language of post-independent literature is much sought after by teenagers compared to pre-independent literature. Sunil Gangopadhyay’s Kakababu series, Satyajit Ray’s Feluda and Professor Shanku series, and Bibhutibhushan Bandopadhyay’s Chander Pahar stand out among the adolescents from both English and Bengali medium unanimously in this chapter.

Abstract

Purpose

This study aims to review and synthesize existing research in the field. Additionally, this study identifies emerging themes and future research opportunities based on the discussions within these studies. This research also develops a model to integrate artificial intelligence with agile human resource (AHR) practices and strives to outline potential directions for future researchers.

Design/methodology/approach

This study adopted a systematic literature review (SLR) and bibliometric analysis followed by content analysis through bibliographic coupling to analyze the identified literature. The SCOPUS database was used in this study, using a search string of keywords to identify the relevant research literature. The initial extraction resulted in 151 articles after adopting a series of inclusion–exclusion criteria, which led to the final attainment of 73 articles to be included for further analysis and discussion.

Findings

This study through the extant literature identified five themes and foundations of artificial intelligence in AHR practices research and developed a model for future investigation by future researchers.

Originality/value

To the best of the authors’ knowledge, this study is one of a kind that explores artificial intelligence within AHR practices for improved employee and organizational well-being. Thus, developing a synthesized work provides a comprehensive picture of the research domain.

Abstract

Twelve pigment compositions derived from the xCaO·(50−x)ZnO·20B2O3·30P2O5·(x=10, 20, 30) and yMgO·(50−y)ZnO·20B2O3·30P2O5·(y=10, 20, 30) systems were prepared. The synthesis was carried out either by the medium‐temperature process or by the high‐temperature process followed by cooling in air and an isothermal crystallisation of the glass obtained. The pigments prepared by the medium‐temperature process achieved better corrosion results in styrene‐acrylate coating formulations, whereas those prepared by the high‐temperature process achieved better results in alkyd‐resin coating formulations. The anti‐corrosion results for the Ca‐Zn pigments were better than those for the Mg‐Zn pigments.

Abstract

Using data over the period from 1950 to 2000, we estimate a model of bilateral international trade to explore the linkages between (a) alliances, (b) joint memberships in international institutions, (c) mutual cooperation and (d) conflict, (e) mutual economic freedom, and (f) democracy and bilateral trade. We incorporate exporter and importer effects as well as reciprocity into a gravity model and cross-validate it against annual out-of-sample data. The resulting, empirical findings show the importance of second and third-order dependencies in bilateral trade data. Military alliances, membership in IGOs, international cooperation, and mutual economic freedom are shown to be strongly associated with bilateral trade. Conversely, conflict and the level of democracy do not demonstrate strong, discernable linkages to bilateral trade.

Abstract

Purpose

Non-alcoholic fatty liver disease (NAFLD) is the most common liver disease which has become a public health concern, whose growing prevalence has been reported as around 33.9% in Iran. As oxidative stress plays a crucial role in the pathogenesis of NAFLD, antioxidant compounds such as quercetin could ameliorate the side effect of oxidative stress. The aim of the current study was to assess the effect of quercetin on lipid profile, liver enzymes and inflammatory indices in NAFLD patients.

Design/methodology/approach

In a randomized, double-blind, placebo-controlled trial conducted as a pilot study, 90 patients with NAFLD were supplemented with either a quercetin or a placebo capsule twice daily (500 mg) for 12 weeks. Both groups were advised to follow an energy-balanced diet with physical activity recommendations. Blood sample was obtained for laboratory parameters at baseline and the end of week 12.

Findings

At the end of the follow-up, quercetin group had significantly greater reduction in anthropometric parameters, cholesterol (−15 ± (−41, 0.00) in Q group versus −1± (−8, 2) in control group, p = 0.004), TG (−56.7 ± 22.7) in Q group versus −13.4 ± 27.7 in control group, p = 0.04), and tumor necrosis factor-α (TNF-α) (−49.5 ± (−99, 21) in Q group versus −5 ± (−21, 0.30) in the control group, p < 0.0001) compared to the control group. However, changes in fatty liver grade, liver enzymes, as well as high density lipoprotein-cholesterol and high-sensitivity C-reactive protein were not significantly different between the two groups.

Originality/value

To the best of the authors’ knowledge, this was the first study which assessed the effect of quercetin supplementation on liver enzymes, lipid profile and inflammatory indices of NAFLD patients as a double-blind placebo-controlled pilot study.

Abstract

Purpose

This paper aims to explore the adsorption kinetics of syringin from Syringa oblata Lindl. leaves on macroporous resin and develop an efficient, simple and recyclable technology for the separation and purification of syringin.

Design/methodology/approach

Static adsorption and desorption properties of six resins were tested to select a suitable resin for the purification of syringin. Langmuir and Freundlich isotherm models were used to estimate the adsorption behavior of syringin on AB-8 resin. Breakthrough point and eluent volume were determined by dynamic adsorption and desorption tests. High-performance liquid chromatography-electrospray ionization-mass spectrometry was applied to identify the syringin in the purified product [syringin product (SP)]. Antioxidant and antibacterial activities of SP in vitro were evaluated by free radical scavenging ability and biofilm formation inhibitory tests.

Findings

AB-8 exhibited the most suitable adsorption and desorption capacity. Adsorption isotherm parameters indicated favorable adsorption between AB-8 and syringin. The optimal results were as follows: for adsorption, the sample concentration was 1.85 mg/mL, the sample volume was 3.5 bed volume (BV), the flow rate was 0.5 mL/min; for desorption, the ethanol concentration was 70%, the elution volume was 2.5 BV, the elution velocity was 1.0 mL/min. SP with 80.28% syringin displayed the potent antioxidant activities and inhibitory effects on biofilm formation of Streptococcus suis.

Originality/value

To the best of authors’ knowledge, there are no reports on purifying syringin from Syringa oblata Lindl. leaves using macroporous resins. This paper may also provide a theoretical reference for the purification of other phenylpropanoid glucosides.

Abstract

Purpose

Although officially ended in July 2020, China’s dispute about its non-market economy (NME) status at the World Trade Organization (WTO) is far from being resolved. The NME status enables China’s counterparts to disregard Chinese prices in antidumping proceedings and instead use the so-called surrogate country methodology. This paper aims to structure and analyze the complex debate, which emerged with the disputes China has filed against the European Union and the USA at the WTO, and therefore provide a point of reference for future analysis of and debates about China’s NME status.

Design/methodology/approach

The analysis is based on the existing academic literature on the topic and on the legal WTO-related documents (e.g. multilateral agreements, China’s Accession Protocol, legal findings of the WTO dispute panels).

Findings

Four different interpretations of the respective legal documents about China’s NME status are discussed and strong and weak aspects of these interpretations are pointed out. Also, several misunderstandings and mistakes appearing in the debate are clarified.

Practical implications

As the question of China’s position at the WTO and its NME status has not been resolved yet and some authors believe that China will pursue its case again once the WTO Appellate Body revives its functionality, the analysis of the debate can serve as a point of reference for the academic debate and the future research on this topic. Moreover, it offers an introduction to China’s NME position at the WTO for the newcomers to this topic.

Originality/value

Although China’s NME status has been much discussed, there is no literature review that would structure the debate and point out some of the (dis)advantages of the respective arguments and interpretations. Rather than adding to the large corpus of literature about the NME status, this study takes this corpus as the object of its analysis.

Abstract

Sages and seers in ancient India specified dharma, artha, kama and moksha as the four ends of a moral and productive life and emphasised the attainment of a proper balance between the spiritual health and the material health. However, most of their intellectual energy was directed towards the attainment of moksha, the salvation from birth‐death‐rebirth cycle. Kautilya, on the other hand considered poverty as a living death and concentrated on devising economic policies to achieve salvation from poverty but without compromising with ethical values unless survival of the state was threatened. Kautilya's Arthashastra is unique in emphasising the imperative of economic growth and welfare of all. According to him, if there is no dharma, there is no society. He believed that ethical values pave the way to heaven as well as to prosperity on the earth, that is, have an intrinsic value as well as an instrumental value. He referred the reader to the Vedas and Philosophy for learning moral theory, which sheds light on the distinction between good and bad and moral and immoral actions. He extended the conceptual framework to deal with conflict of interest situations arising from the emerging capitalism. He dedicated his work to Om (symbol of spirituality, God) and Brihaspati and Sukra (political thinkers) implying, perhaps, that his goal was to integrate ethics and economics. It is argued that the level of integration between economics and ethics is significantly higher in Kautilya's Arthashastra than that in Adam Smith's Wealth of Nations or for that matter in the writings of Plato and Aristotle.
