Password Manager：SecureSafe vs DBM Lookup Utility

Password manager with safe performance, powerful functions and simple interface! -------------------------------------------------- Do you often forget your password? "Password Manager" can help you remember all passwords and keep them safe, you only need to remember one application login password! This application is a simple and practical account password management software. Each of us has many different website accounts and passwords, such as QQ, WeChat, Weibo, etc. If each website is set to the same account and password, once an account is leaked, the account and password on other websites are at risk of being stolen. Setting different high-strength passwords on different websites is the safest guarantee, but it is difficult to remember such a variety of account passwords. Therefore, it is very necessary to have a safe and practical password management software! ### Safety ### This application does not have any network connection at all, and all information is stored locally on the phone. Safe and reliable ### Simplicity ### This application uses a simple interface, you who like simplicity deserve it ###Auto-Renewal Terms### ●Subscription price: Weekly membership (¥20/month) Annual membership (¥98/year) ● Subscription payments will be charged to your iTunes account at confirmation of purchase and at the beginning of each renewal period ● Renewal: Apple iTunes account will be deducted within 24 hours before expiration, and the subscription cycle will be extended by one subscription cycle after the deduction is successful. ● Cancel Renewal: You can cancel your subscription or trial at any time by going to your iTunes account settings and canceling the subscription, otherwise it will automatically renew.

DBM Lookup Utility finds the feasible distillation boundary maps (DBMs) for any ternary mixture, using only the relative boiling points of its pure components and azeotropes. No thermodynamic modeling or residue curve sketching required. DBMs are simplified residue curve maps. They show how a three-component mixture divides into distillation regions, and they're a key tool in the conceptual design of distillation processes. Finding the right map by hand means working through nodes, saddles and topological consistency. This app does it with a lookup. THREE WAYS TO FIND A MAP • Azeotropes: say whether each binary and ternary azeotrope exists and whether it's minimum- or maximum-boiling (or a saddle). Leave anything you don't know as "???" and the app keeps every possibility. The 307 possible temperature sequences (TSs) narrow down as you go. • Example: pick one of six preloaded systems, such as Methanol/Ethanol/Water or Acetone/Chloroform/Methanol, and see its TS and DBMs instantly. • Enter TS: type a temperature sequence you already know. The app checks it as you type and tells you what's wrong if it isn't valid. Then choose a TS and one of its DBMs to see the map drawn on the composition triangle. ALL 125 DBMs Browse a gallery of all 125 unique distillation boundary maps. Tap any one to see it full size, along with every temperature sequence that produces it. Each map is labeled with its Matsuyama–Nishimura classification code. USEFUL FOR • Screening entrainers for azeotropic or extractive distillation • Quick "what-if" checks during conceptual process design • Teaching and learning ternary VLE behavior Only thermodynamically feasible TSs and valid DBMs are generated, so you never have to judge inconsistent or indeterminate maps yourself. Based on the method published by Peterson and Partin, "Temperature Sequences for Categorizing All Ternary Distillation Boundary Maps," Ind. Eng. Chem. Res. (1997), and cited in Perry's Chemical Engineers' Handbook. Note: the app identifies which maps are possible. Experimental VLE data is still needed to pin down the exact boundary curvature for a specific mixture.
