Important factor that determines the concentration of fluoride in groundwater is availability and the solubility of F minerals, pH, temperature, anion exchange capacity of aquifer materials, type of geological materials and residence time, porosity, structures, depth, groundwater age, the concentration of carbonates and bicarbonates in the water (Apambire et al. 1997; Kim and Jeong 2005).
"Vert-Galant" has structure, depth, character and impact.
For the vertical competence structure (depth of competence)—shaping the proficiency level model (Hartig and Klieme 2006, p. 133)—various competence profiles are assumed.
The electric field variation with structure depth from surface to bottom and as a function of 2DEG density has also been investigated.
We optimized the demolding setup to be able to compare ideal demolding processes with a range of process parameters, i.e. pattern design, structure depth and demolding temperature.
The surface structure transition was shown in Fig. 1(b'), a hole structure (depth: 4 nm, width: 20 nm) was appeared at the point of applying voltage, and a ring structure (93 × 101 nm2) was appeared around the hole structure.
A hole structure (depth: 1.4 nm, width: 15 nm) was appeared at the point of applying voltage, and a ring structure (45 × 50 nm2) appeared around the hole structure as shown in Fig. 1(c').
The tendency for the reflection decrease due to the increase of NHA depth over the solar spectrum of 350 to 800 nm may be attributed to the smaller refractive index gradient with respect to structure depth [32].
The parameters were: the soil/ground type, excavation size, excavation depth, proposed methods of excavation and ground support, proximity of the nearest structure, depth of water below ground level, and permeability of the ground.
For broadband antireflection or a wide range of incidence angles, a distinct structure depth together with a very low lateral structure size is required, which is difficult to realize.
Moreover, metals with short thermal diffusion lengths present very homogeneous structures and the structure depth that can be achieved at relatively high laser fluences during single-pulse experiments is on the order of the diffusion length.
