Article Synopsis
- Highly porous nickel-based superalloys, specifically Hastelloy-X, are being explored as alternatives to honeycomb structures in gas turbine engine seals due to their favorable properties.
- The study focuses on a space holder method for producing these materials, highlighting its economic and ecological advantages, and uses spherical Hastelloy-X powders combined with carbamide particles.
- The research includes advanced inspections like X-ray computed tomography and tests on the mechanical properties of the porous samples, revealing how different levels of porosity (50%, 60%, and 70%) impact their compressive strength.
Arthropod-borne viral infections caused by dengue virus (DENV) and chikungunya virus (CHIKV) are prevalent in the same regions and are spread by the same mosquito type (Aedes) and have similar clinical manifestations. This study emphasized the challenges of diagnosing fever in a patient returning from a tropical area. We report a case of a 52-year-old patient who presented with fever, myalgia, and headache after travelling to Laos and Thailand.
