Abstract: Provided is an inlet bulkhead for large diameter aircraft engines. The inlet bulkhead, in certain examples, includes an annular body having an outer flange, an inner flange, and a web having a first side and an opposing second side. The web extends from the outer flange to the inner flange. The bulkhead also includes at least one annular stiffener disposed on the first side, and multiple radial stiffeners disposed on the first side, each of which extend from the outer flange to the inner flange. The annular and radial stiffeners may be integrally formed with the web.

Abstract: A first input to a mobile device indicates a first navigation destination at a first level of specificity. The mobile device initiates navigation towards a first location corresponding to the first navigation destination. While navigation towards the first location corresponding to the first navigation destination is ongoing and before reaching the first location, in accordance with a determination that one or more first criteria are satisfied, the mobile device prompts for an input for determination a second location corresponding to a second navigation destination with a second level of specificity, the second level of specificity more specific than the first level of specificity. The mobile device receives a second input in response to the prompt. In accordance with a determination that the second input satisfies one or more second criteria, the mobile device initiates navigation towards the second location corresponding to the second navigation destination.

Abstract: This invention provides compositions and methods for fixing biological samples, particularly fecal samples used in the diagnosis of parasitic infection. The fixative composition of the present invention includes a zinc salt, an organic acid and water and permits staining of biological samples without use of toxic compounds, such as formaldehyde and mercury-containing compounds and without the use of additives such as polyvinyl alcohol. The fixative composition and methods are compatible with many diagnostic assays, including trichrome stains, iron hematoxlin, ELISA, fluorescent assays, and lateral flow assays.
