Bookends vs SlurryBase

Bookends is the reference management app you've been looking for. The basic version offers: • Search online sites directly (arXiv, Google Books, Google Scholar, JSTOR, the Library of Congress, PubMed, PubMed Central, and Semantic Scholar) or use the built-in browser (EZProxy-compliant) to download reference metadata and PDFs (access privileges required). Searches can return a maximum of 20 references, and only 50 references can be stored in your personal database. • Use unique identifiers such as DOI, PMID, ISBN, or arXiv id to autofill references. • View the text of PDF annotations in a note stream, and create your own with our powerful PDF markup engine. • Barcode scanning, one per day. • And many more features designed to help you discover, organize, and use reference information.

SlurryBase is an offline logbook for Material Records and indicative slurry pipeline calculations. Review model applicability, assumptions, citations, warnings, and input basis. The automatic settling policy uses equivalent fluid below critical LDV, a disclosed transition blend through the safety band, and GIW 4-component where its source-audited input policy applies. Outside that policy, uncorrected equivalent fluid remains a screening fallback. Durand and a simplified two-regime settling estimate are comparison/manual options; the full DHLLDV framework is not implemented. Compare Calculation Cases and export PDF/CSV datasheets with their evidence context. Engineering records stay on your device and calculations work offline; purchases, restore, update checks, and external links require connectivity. Verify results against project standards and obtain expert review before design. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
