When the vibrant dramatization of Anne Lister stormed screens across the globe in Gentleman Jack, she sparked interest in both the real Lister and the women in her life. Among them is her partner, Ann Walker, who was a constant presence in Lister's later life. Given that archival sources connected to Walker are fairly limited in volume and scope, studying her is challenging and requires a combination of different resources, among them Walker's letters and journal. These allow for a better understanding of Ann Walker but are not comprehensive enough to cover most of her life. Thus, to obtain a broader perspective of Walker, it is necessary to consult documents that belonged to her contemporaries. What can one learn about Walker from her perspective? How can Walker's contemporaries fill in the gaps that aren't covered by her papers? And how will these perspectives affect interpretations of Walker? In this article, I provide an overview of the materials that can be used to study and understand the real Ann Walker, both from her perspective and that of others. This article also provides suggestions on keeping a neutral approach to interpreting Walker while using different resources as sources. [ABSTRACT FROM AUTHOR]

The current study aims to investigate the scientific research on the technological theme and thus understand the basis of its support. It aims to outline the profile of scientific literature on technology in LIS through a descriptive and quantitative research based on scientometric studies of scientific communication. The source of the research was the Referential Database of Information Science Periodical Articles (BRAPCI) using the terms 'computer', 'automation', 'information systems', 'technology', 'electronic', 'e', 'digital' and 'virtual' gathered to analyze the technological base area of 353 articles. Results indicated that the articles were published between 1972 and 2008, outlining the year of 2001 with the largest quantity (29) and a decreasing setting in the last decade. The journal with the highest number of publications is Information Science (166); 82% of the authors have up to 2 published articles on technology, indicating that the subject has no homogeneous group work nor research continuity; and the most recurrent terms are "information" and "systems" and "technology". Seven thematic domain groups that constitute the technological basis of the field were identified: the most representative of them is led by 'information systems', followed by 'digital and virtual library'; policy issues involving 'internet and network'; 'computer teaching librarianship'; 'automatic indexing', 'knowledge management, and electronic publishing'.

Background: Lignin is known to hinder efficient enzymatic conversion of lignocellulose in biorefining processes. In particular, nonproductive adsorption of cellulases onto lignin is considered a key mechanism to explain how lignin retards enzymatic cellulose conversion in extended reactions. Results: Lignin-rich residues (LRRs) were prepared via extensive enzymatic cellulose degradation of corn stover (Zea mays subsp. mays L.), Miscanthus × giganteus stalks (MS) and wheat straw (Triticum aestivum L.) (WS) samples that each had been hydrothermally pretreated at three severity factors (log R0) of 3.65, 3.83 and 3.97. The LRRs had different residual carbohydrate levels—the highest in MS; the lowest in WS. The residual carbohydrate was not traceable at the surface of the LRRs particles by ATR-FTIR analysis. The chemical properties of the lignin in the LRRs varied across the three types of biomass, but monolignols composition was not affected by the severity factor. When pure cellulose was added to a mixture of LRRs and a commercial cellulolytic enzyme preparation, the rate and extent of glucose release were unaffected by the presence of LRRs regardless of biomass type and severity factor, despite adsorption of the enzymes to the LRRs. Since the surface of the LRRs particles were covered by lignin, the data suggest that the retardation of enzymatic cellulose degradation during extended reaction on lignocellulosic substrates is due to physical blockage of the access of enzymes to the cellulose caused by the gradual accumulation of lignin at the surface of the biomass particles rather than by nonproductive enzyme adsorption. Conclusions: The study suggests that lignin from hydrothermally pretreated grass biomass retards enzymatic cellulose degradation by acting as a physical barrier blocking the access of enzymes to cellulose rather than by inducing retardation through nonproductive adsorption of enzymes.
