Fuel properties of loofah oil and its ethyl ester blended with diesel were experimentally determined. Biodiesel blends (10, 20, 30, 40, 50, 60, 70, 80, 90 and 100%) of loofah oil and its ethyl ester by volume with diesel was used. The fuel properties of the biodiesel blends were determined according to American Society for Testing and Materials (ASTM) standards. Pure Automotive Gas Oil (AGO) wa...

In this paper, we identify higher-order differential and zero-sum properties in the full Keccak-f permutation, in the Luffa v1 hash function, and in components of the Luffa v2 algorithm. These structural properties rely on a new bound on the degree of iterated permutations with a nonlinear layer composed of parallel applications of smaller balanced Sboxes. These techniques yield zero-sum partit...
