Assamese Identity Issues: A Chapter Review of 'India's North-East: Identity Movements, State and Civil Society'
No full textThis commentary article discusses the chapter titled ‘Assam: Identity Movements and Insurgent Politics’ – ‘Assamese Identity Issues’ in Udayon Misra's book "India’s North East: Identity Movements, State and Civil Society" (2014), focusing on the Assam movement and its implications for Assamese identity. The author sheds light on how the movement was centered around the issues and questions between foreign migrants and indigenous people, highlighting the struggle for linguistic identity and the yearning for a unified homeland. The commentary also underscores the need for social and political cohesion, effective conflict management, and inclusive governance to ensure a peaceful resolution and foster the development of Assamese society. It provides a comprehensive analysis of the historical context, starting with rich debates spanning over many decades

No full textA Heuristic Approach for Machine Cell Formation Problems with Alternative Routings
No full textAbstractCell Formation (CF) is an important problem in today's automated batch type production systems. It reduces material handling cost, processing time, labor requirement, in-process inventories, number of set-ups, simplifies process plan, and increases quality of product. Manufacturing equipments of automated manufacturing systems are highly multifunctional. As a result, production processes can be done by multiple process routes. Optimum cell formation can lead to more independent cells and less intercellular movement of parts. Previous research reveals that most of the researchers considered single route, unique volume of parts, non-sequential Cell Formation Problem (CFP). However, intercellular movements of parts depend on parts volume, sequence of processes, and routes. In this paper, a heuristic approach based on Euclidean Distance matrix is proposed for CF in multiple routes, process sequential and parts volume (included with batch size and number of batches) problems. Computational experiments were performed with five benchmark problem sets taken from the literature and the results demonstrate that the performances of the proposed heuristic in terms of intercellular movements of parts are either better than or competitive with the well-known existing algorithms
A Scientometric Introspect of Literary Warrants Published in Annals of Library and Information Studies (ALIS) during the Last Decade
No full textScientometric studies are enduring studies that portray an organized visual of messy data. The current study is a scientometric study based on secondary data sets included in Scopus. A corpus of 311 documents published in the journal Annals of Library and Information Studies (ALIS) from 2011 to 2020 was the population of the study. The study focused on several characteristics of the journal, including article distribution, average author per document, average document per year, authorship productivity, collaboration index, country-wise distribution of documents and citation analysis. The study retrieved the most prolific author contributing to this journal with 19 articles. The Council of Scientific and Industrial Research (CSIR) and the University of Delhi were the top literary contributors to the ALIS journal. The University of Kerala got the most citations per document (6.833). The maximum count of author keywords (Scientometrics) used in the journal from 2011 to 2020 was 135
Water desalination using graphene oxide-embedded paper microfluidics
No full textThe need for the removal of salt constituents is very critical in several downstream processes of biological materials and saltwater purification. Substantial efforts to drive low cost-effective techniques for desalination are ongoing, and it is hopeful that novel nanomaterials could provide useful insight to a new paradigm in salt capturing both in biogenic fluids and complex solutions like seawater. In this report, we demonstrate a microfluidic proof-of-concept for a desalination system, in which graphene oxide deposited on the paper substrate was used to remove salt-ion concentration. Our investigation suggests that the optimal modification of paper with the five-time deposition of graphene oxide (paper@5GO) shows the best salt removal performance with the salt-rejection efficiency of ~ 97.0%. The salt rejection occurs by the phenomenon of surface adsorption on the GO-modified paper membrane which is confirmed by the detailed analytical studies of pre- and post-treatment. The system presented does not require additional energy input in the process and thus would become cost-effective and scalable with high salt removal efficiency which may be useful in bioanalysis and saltwater purification for sustainable development

Immobilization of Cr(III) and Cr(VI) from contaminated aqueous solution by using sewage produced biochar: Affecting factors and mechanisms
No full textThe present study focuses on adsorption of chromium (trivalent and hexavalent) by using sewage-produced biochar as well as reduction of the produced sewage. Biochar is produced from municipal sewage to examine the capability of two biochars i.e., prepared at 450°C SWB450 and 550°C SWB550 to sorb trivalent chromium [Cr(III)] and hexavalent chromium [Cr(VI)] using batch experiments. Brunauer Emmett Teller (BET) data indicated higher surface area of SWB550 compared to SWB450, which supports the field emission scanning electron microscope (FESEM) results. 4 g L−1 biochar doses emerged as the optimum for Cr(III) and Cr(VI) removal for both biochars at pH 5.0. Performance of SWB550 was 92.9% for Cr(III) and <40% removal for Cr(VI). Energy dispersive X-ray (EDX) spectroscopy and Fourier transformation infrared (FTIR) study confirmed the Cr loading on both the biochars. Adsorption isotherm and kinetic models confirmed that the mechanisms behind the sorption of trivalent and hexavalent Cr on SWB450 and 550 biochar were physical sorption and chemical sorption processes. Adsorption via biochar is a cost-effective and simple process compared to electrodialysis, ion exchange, chemical precipitation, membrane filtration, electrocoagulation, bioremediation, photocatalysis, etc. Present study provides an effective biochar for Cr removal from wastewater as well as reduction in the generated waste through pyrolysis.</p
