Photographic elements, processes for forming images in photographic elements and new compounds are disclosed. Generally, the invention relates to immobile compounds which can be used to provide positi
elements encountered during these processes. Experiments confirm that the magnetic factor and angle of inclination contribute to a reduction in the velocity profiles of nanofluids and hybrid nanofluids. Nanofluid and hybrid nanofluid velocity and temperature exhibit a directional correlation with the ...
