The Scheme of Library Classifications: Concerning the Structural changes of 23rd Dewey Decimal Classification (DDC)

The Dewey decimal classification system is continuously revised to keep pace with knowledge. This means accommodating new topics, as well as revising the old one. Today the Dewey decimal classification has undergone 22 revisions to keep itself abreast of the ever advancing frontiers of knowledge and to cater the increasing demand of its users Edition 23. It is regularly (quarterly) to cope up with the pace of increasing universe of knowledge. This article has been made discussion about the modification revised version of 23 DDC edition and its features, updates and subscription information etc

Reducing the environmental impact of surgery on a global scale: systematic review and co-prioritization with healthcare workers in 132 countries

Background Healthcare cannot achieve net-zero carbon without addressing operating theatres. The aim of this study was to prioritize feasible interventions to reduce the environmental impact of operating theatres. Methods This study adopted a four-phase Delphi consensus co-prioritization methodology. In phase 1, a systematic review of published interventions and global consultation of perioperative healthcare professionals were used to longlist interventions. In phase 2, iterative thematic analysis consolidated comparable interventions into a shortlist. In phase 3, the shortlist was co-prioritized based on patient and clinician views on acceptability, feasibility, and safety. In phase 4, ranked lists of interventions were presented by their relevance to high-income countries and low–middle-income countries. Results In phase 1, 43 interventions were identified, which had low uptake in practice according to 3042 professionals globally. In phase 2, a shortlist of 15 intervention domains was generated. In phase 3, interventions were deemed acceptable for more than 90 per cent of patients except for reducing general anaesthesia (84 per cent) and re-sterilization of ‘single-use’ consumables (86 per cent). In phase 4, the top three shortlisted interventions for high-income countries were: introducing recycling; reducing use of anaesthetic gases; and appropriate clinical waste processing. In phase 4, the top three shortlisted interventions for low–middle-income countries were: introducing reusable surgical devices; reducing use of consumables; and reducing the use of general anaesthesia. Conclusion This is a step toward environmentally sustainable operating environments with actionable interventions applicable to both high– and low–middle–income countries

Lanthanum oxyfluoride nanostructures prepared by modified sonochemical method and their use in the fields of optoelectronics and biotechnology

Dysprosium doped lanthanum oxyfluoride nanostructures were prepared by modified sonochemical method using Aloe Vera gel as a bio-surfactant. The morphology of the product was systematically studied by varying different experimental parameters including concentration of surfactant, sonication time, pH and sonication power. It was found that some of these above parameters play a key role in tuning the morphology of the product. The photoluminescence studies exhibited characteristic emission peaks at ∼483 nm, 574 nm and 674 nm attributed to 4F9/2 → 6H15/2, 4F9/2 → 6H13/2 and 4F9/2 → 6H11/2 transitions of Dy3+ ions respectively. The optimal concentration of Dy3+ ions was found to be ∼3 mol%. The photometric studies revealed that the prepared samples were quite useful for the fabrication of white light emitting diodes. The optimized product was also tested for their capability as an antigen against the bacterial and fungal pathogens. The present method of preparation may be scaled up easily to the larger production for industrial applications. The optimized sample showed an effective visualization of latent fingerprints on various forensic relevant materials and also showed effective antimicrobial potential for applications in nanobiotechnology

Facile LaOF: Sm3+ based labeling agent and their applications in residue chemistry of latent fingerprint and cheiloscopy under UV–visible light

Luminescent lanthanum oxyfluoride nano inorganic materials were considered to be prospective building blocks for multifunctional applications. This offers new potentials in surface-based science comprising of visualization of latent fingerprint (LFPs) and lips print on non-porous surfaces. Traditional visualization techniques possess high backward hindrance, low sensitivity, complicated setup and poor visibility. To overcome with these problems, LaOF:Sm3+ (5 mol%) nanopowder (NPs) prepared via sonochemical route were explored. Photoluminescence (PL) emission spectra exhibit strong emission peaks at ∼566 nm, 607 nm, 653 nm and 708 nm attributed to 4G5/2 → 6H5/2, 4G5/2 → 4H7/2, 4G5/2 → 6H9/2 and 4G5/2 → 6H11/2 intra-4f orbital transitions of Sm3+ ions respectively. Estimated photometric properties confirm that the material emits warm orange red color. Therefore, the synthesized phosphor materials may quite be useful for LFPs recovery, cheiloscopy and optoelectronics applications.
