Reading James Jackson: Who's the author?:Reading Race, Collecting Cultures - The Roving Reader Files: 'Reading James Jackson'
No full textThe Ahmed Iqbal Ullah Race Relations Resource Centre is an open access University of Manchester facility. The blog 'Reading Race, Collecting Cultures' (www.aiucentre.wordpress.com) features on its website (http://www.racearchive.manchester.ac.uk). The Roving Reader Files category of blog posts is produced by Alison Newby (under the pseudonym The Roving Reader) in collaboration with Hannah Niblett (Collections Access Officer). The former provides the text and the latter provides the images. The Roving Reader Files are designed as public engagement materials. The intention is to introduce research skills and terminology to the general user/reader in an entertaining yet informative manner by revealing hidden stories, making unusual connections and sharing insights into using the Centre's collection for research. The related posts "Reading James Jackson: Who's the author?" and "Reading James Jackson: Footnotes" introduce readers to biography; scholarly editions and the role of the editor; the importance of contextualising sources in their historical period; footnotes and their uses

No full textContributions to the Field of Library and Information Sciences in Pakistan: A Bio Bibliometric Study of Dr. Saeed Ullah Jan
No full textAbstract
Purpose- This paper presents the bio-bibliometric analysis of Dr. Saeed Ullah Jan\u27s contributions to the Library and Information Science (LIS) field in Pakistan. This study includes the following: the year-wise distribution of research produced; authors\u27 collaboration; publications by type; language; geographical preference for research; and coverage of different subject areas.
Methodology/Design- The data for this retrospective study was requested through email from Dr. Saeed Ullah Jan with advance ethical permission and further verified from Scholar Google, the official university website, and departments where required.
Findings- The results of the study indicate that Dr. Saeed Ullah Jan is a prolific writer and supervisor in LIS in Pakistan. He contributed 178 items, including 76 articles, two books, 86 theses, and fourteen conference papers, and secured eleven research grants until June 30, 2022. His most significant contribution is establishing two LIS departments with two postgraduate LIS education (MPhil and PhD) programs for the first time in Khyber Pakhtunkhwa. He has the honor of launching the first LIS Higher Education Commission (HEC) recognized research journal from the fertile land of Khyber Pakhtunkhwa, Pakistan. Research work by Dr. Saeed Ullah Jan has received worldwide recognition and has been accepted in leading journals in the United Kingdom, Canada, Japan, and the United States of America. He used the English language to publish the majority of his research work. He believes in teamwork, and about 98% of his research work was done in collaboration. He is also an HEC recognized and approved Ph.D. supervisor.
Originality- This study is a unique biobibliometric study that systematically combined the research productivity of Dr. Saeed Ullah Jan and provided a holistic sketch of the literature produced on various themes of LIS during 2011–2022.
Research limitations- Due to the limited area of biobibliometrics of a single author, the results were not generalized
CO2 electroreduction to C2 products on bimetallic silver copper melamine complexes
No full textNanocube crystals of bimetallic Ag-Cu-Melamine molecular complexes have been originally developed as effective electrocatalysts for the CO2 selective reduction to multicarbon products, particularly ethylene and ethanol. The bimetallic complex, containing 10 wt.% Ag demonstrates the highest performance in electro-reduction of CO2 in both H-type and flow cells. It achieves a Faradaic efficiency of 70 % for C2 products, with 40 % attributed to ethanol and the remaining to ethylene. These results are obtained at a cathode potential of -1.0 V vs reversible hydrogen electrode (RHE) with a total current density of -50 mA·cm-2 in the flow cell, five times higher current densities than the current densities in the H-Cell. Without Ag in the complex, only C1 products (CO and formic acid) are detected. The use of the flow cell, in addition to higher current densities, enhances C2 formation, especially ethylene, which is absent in H-type cell experiments. These novel electrocatalysts also exhibit stable performances and provide mechanistic indications of the roles of Ag and tandem cooperation with Cu
Comparative metabolite profiling of drought stress responsive biochemical pathways in root and leaves of triticeae species
No full textAn untargeted metabolite profiling was applied to modern wheat and wild relatives exposed to drought stress using Gas Chromatography-Mass Spectrometry technique. A total of 84 analytes were resolved in the wheat metabolome for which multivariate analyses including supervised (Principal Component Analyses) and unsupervised (Partial Least-Squares-Discriminant Analysis) provided significantly variable dataset under control and drought stress conditions. Around 45 significantly altered metabolites, with possible roles in drought stress, were identified in all species tested through the GC-MS study. The potential drought stress responsive metabolites were further investigated to track genes encoding the enzymes of selected biochemical pathways using FL-cDNA sequences and transcriptome data. It has been hypothesized that if the genes encoding the enzymes that control the biosynthesis of drought stress-specific metabolites have a significant role in tolerance, contrasting genotypes would have a variance in the metabolite content. A small proportion showed a reduction in the metabolite accumulation in the drought sensitive genotypes, indicating that selected genes are directly or indirectly engaged in metabolome-regulative biochemical pathways under water-limiting conditions. These results demonstrated that those specific genotypes with high drought tolerance skills, especially wild emmer wheat, could be genetic model systems for experiments to validate metabolomics–genomics networks
British Rule in the Subcontinent, Literary Movements, and the Authors of the Partition Period: Qudrat Ullah Shahab
No full textDue to the rapid development of events since the 19th century alongside the British rule of the Indian subcontinent, genres such as novels and short stories were left out of Urdu literature. At that time, poetry had a great influence on mobilizing the masses, and a poetry-oriented trend had occurred in Urdu literature. However, at the beginning of the 20th century when Qudrat Ullah Shahab lived, an important Urdu literature writer and subject of the article, stories and novels are seen to have gained popularity alongside the poetry genre. Although prose had come about from Western literary figures in this period, these writers had dealt with stories specific to their own regions. As the people found their lives in these works, prose also consolidated its place in literature. Qudrat Ullah Shahab lived between 1920-1986, the period thatwitnessed the division of Pakistan and India, and succeeded in reflecting the painful life stories of this period in his stories as best he could. This study aims to introduce the life, literary personality, and works of Qudrat Ullah Shahab as one of the important writers of the Indian subcontinent who lived through the Partition period and was especially famous for his autobiography titled Shahabnama. Before talking about the author in this context, mentioning the situation of the subcontinent and the literary movements regarding the types of prose in his period would be appropriate
User Satisfaction Level of SCEE NUST Islamabad Library from Library Services Quality
No full textThe purpose of the study is to empirically investigate the relationship between the quality of services provided by the library and the level of user satisfaction from these services. The data was collected with self administered questionnaires from the SCEE NUST (School of Civil and Environmental Engineering, National University of Science and Technology) library users. The study used regression analysis to analyze the data. Results show a significant positive relationship between library services quality and user satisfaction. The article also provides some practical implications based on the results. Limitations and future research directions are also mentioned
