This study was designed to examine whether anxious personality, i.e. trait anxiety, influences the autonomic nervous functions in humans without manipulation of experimental stressors.
The experimental instrumentation, including the loading device, and the procedures for the manipulation of experimental data are detailedly described; experimental results obtained on a steel specimen and a composite laminate are also reported.
In particular, NG of various architectures such as rods, plates, disks, cubes, spheres, stars, etc. can be synthesized by proper manipulation of experimental parameters in the presence of a macroscopic shape-regulating agents in the form of polymer [9, 10, 11, 12, 13, 16].
Gold NPs of various structural architectures (e.g., rods, plates, disks, cubes, spheres, and stars) can be synthesized by proper manipulation of experimental parameters in the presence of surface-capping agents in the form of surfactants[3, 17], polymers[3, 4, 5, 6, 7], and dendrimers[3, 6].
Blake and Scallion, in an article in the Journal of Computer Assisted Learning, report that computer simulations allow time saving, easy manipulation of experimental variables and provide support in understanding representations, such as diagrams and graphs.
The manipulation of experimental animals should also be minimized.
All manipulations of experimental animals were conducted in a laminar flow hood using strictly controlled procedures adhering to the UKCCCR Guidelines for the Welfare of Animals in Experimental Neoplasia to minimise stress or suffering (UKCCCR, 1998).
Differently from humans, experimental models in animals offer the advantage to allow an easier manipulation of key experimental variables for the investigation of psychosocial factors affecting vulnerability to stress exposure [7], [13] [16].
The manipulation of the experimental composites was carried out under filtered orange light.
Measurements performed in isolated cell subsets are easy, precise and allow significant manipulation of multiple experimental variables.
The major limitation of this study was the difficulty of manipulation of the experimental resin due to the absence of filler particles.
