These researchers acknowledge the difficulty of studying an animal's mental state, but say such hurdles should not preclude animal thinking from being the subject of scientific research.
While the tastiness of morels is well understood, the difficulty of studying them in the wild makes them something of a mystery and pinpointing where they might appear difficult.
This was in the Christian contemporary rock section of music stores, deploring the difficulty of studying the Word of God amid the cacophony of "a world that's wired for sound".
The ability to fund a college course is, unsurprisingly, one of the main barriers for adults who would like to return to education (also, of course, the difficulty of studying part-time while working full-time).
Delogne (1991) generated a regulation of electromagnetic wave transmissions and indicated the difficulty of studying practical transmissions in tunnels.
The difficulty of studying the metal/solution interfacial region makes the use of non-conventional measurement techniques indispensable.
The lack of definitive platelet markers is at least partly due to the difficulty of studying platelet function ex vivo.
Excitatory control of inhibitory neurons is poorly understood due to the difficulty of studying synaptic connectivity in vivo.
Yet, many mechanistic details associated with metastasis remain elusive due to the difficulty of studying cancer cells in relevant 3D microenvironments.
In order to significantly downgrade the difficulty of studying energy transport processes within a CNT, some authors often resort to simplified low-dimensional systems such as one-dimensional lattices [23 28].
The influence of early formed dietary practices on food choices and preferences during adulthood has often been assumed but rarely adequately demonstrated given the difficulty of studying the subject matter with conventional laboratory or observational research designs.
