In some other cases the reinforcement is represented by a pre-cured FRP grid, inserted within the inorganic plaster.
More dramatic, the tiered compositions of "Bye Bye Blackbird" and "Underworld" include actual fields of solid color, freestanding verticals and, most evocative, an enlarged partial grid inserted across the canvas's top edge.
The method also has conceptual similarities to some of Hillier's investigations in 'the laws of the field' (Hillier 1996b) where he identifies how within the confines of a grid, inserting walls have different distance and configurational effects depending on where in the field they are added and consecutively where additional walls are added in relation to earlier additions.
A grid, inserted only in the visible illumination path, would not show up in the FFOCM images.
We used a square grid inserted in a focusing eyepiece and determined the volume densities of mast cells.
For that, a grid inserted into the illumination path of the microscope was focused on a sample so as to produce one-dimensional sinusoidal excitation.
This was carried out by H.F.H. in a light microscope, with a 10 × 10-square grid inserted into the eyepiece and a ×25 objective lens.
The mucosal infiltration of polymorphonuclear leucocytes (PMNs) was assessed by P.H. in a light microscope, with a 10 × 10-square grid inserted into the eyepiece, a ×50 oil immersion objective lens (N.A. 1.4) and an oil immersion top lens of the condenser (N.A. 1.4).
As previously reported [ 3, 54], a semi-quantitative analysis was done using an Olympus microscope and examining in each section, high-power non overlapping fields (of 0.0655 × 0.0655 mm width, each corresponding to 4.290 μm), defined in the center of the lesion using a square grid inserted into the eyepiece.
It was found, that the grid anode insert allowed the Ti cathode to be operated with magnetic field intensities in the anode up to a level sufficient for coupling with the magnetic filter field (∼ 20 mT).
