Substrate. The pelagic larval period ends when stage IV postlarvae settle to the bottom. Postlarvae will actively seek suitable substrate with a series of descents and will delay molting to fifth stage until successful settlement is completed. Howard and Bennett (1979) and Pottle and Elner (1982) found that lobster tend to choose gravel rather than silt/clay substrates. However, when Botero and Atema (1982) included macroalgal-covered rock in the choice options, it was preferred by settling lobster, followed by rocks on sand, mud, and sand. Cobb et al. (1983) found postlarvae settle rapidly into rock/gravel, macroalgal-covered rock, salt-marsh peat, eel grass, and seaweed substrates. Barshaw et al. (1985) and Barshaw and Bryant-Rich (1988) observed postlarval lobster to settle quickly into eelgrass, followed by rocks with algae in sand, then mud. Barshaw and Bryant-Rich (1988) emphasized the importance of macroalgal-covered rock habitat and the faster settlement of post larval lobster into it compared to rock and mud, and a lower rate of lobster mortality experienced on it. Although mud habitat is the least preferred, the demonstrated ability of lobster to burrow into it (MacKay 1926; Cobb 1971; Berrill and Stewart 1973; Botero and Atema 1982) implies that when mud habitat is the only option, postlarvae will settle into it and construct and maintain burrows there. Under experimental conditions Stage IV lobsters settled within 34 hours of searching on macroalgal-covered rocks, within 38 hours on scattered rocks in sand, and within 62 hours over mud bottom (Harding 1992). The importance of macroalgal covered rock, eel grass, peat and other habitat types which greatly exceed the total area that inshore cobble represents throughout the range of the lobster may have been underrated when considering a bottleneck hypothesis (Caddy 1986) which isolates cobble as the key habitat. Appropriate habitats protect postlarvae from predation and provide food and shelter thereby minimizing movement and exposure. Lobster may not leave their burrows until they reach a carapace length between 20 and 40 mm (Bryant-Rich and Barshaw 1988). However, a shift from this shelter- based existence to a wider ranging, foraging lifestyle may occur with the greater energy needs and possible mitigation of predation associated with increasing body size. Lobsters in this early benthic phase (5-40 mm CL) were found by Wahle (1988) and Wahle and Steneck (1991) to be most abundant in cobble and macroalgal-...
Substrate. Material in structures must match the natural stream channel. Bed materials should match natural stream bed mobility characteristics. Bank and other key bed structural elements (e.g. steps, weirs, ribs, etc.) must be stable at the 100-year flow.
Substrate. The substrate was 300 nm thick thermally grown sil- icon dioxide on the Si substrate. In addition, hexam- ethyldisilazane (HMDS) was vapor coated on the silicon dioxide surface to decrease the surface energy and make FIG. 2. line stability as a function of drop spacing, with drop spacing decreasing from left to right. a) individual droplets
Substrate. Electrochemical behavior and stability of the substrate provides basic information about exploitable potential window which may significantly influence final application of the sensor with electrodeposited AgAPs. This has been found essential mainly in e.g. DNA or protein electroanalysis [3], which requires electrochemically stable substrate providing a broad negative potential window. Anodic and cathodic parts of potential windows of already studied substrates (ITO, gold or pyrolytic graphite) are limited by anodic dissolution (oxidation) of electrodeposited AgAPs and by hydrogen evolution proceeding either on the substrate or AgAPs, respectively. This depends on relative surface coverage (a ratio between AgAPs’ and substrate surface areas) of the AgAPs on the substrate, since silver amalgam offers the hydrogen overpotential as comparably negative as metal mercury and thus more negative then ITO, gold or pyrolytic graphite. Here it should be reminded, that ITO is reduced before hydrogen evolution reaction and thus applicable potential window is significantly limited (from about+0.1 to −1.0 V) [1]. It has been experimentally found, that electrochemical reactions including hydrogen evolution prevail on AgAPs, when the relative surface coverage exceeds 40 %. Exploitable potential windows (herein defined by the limiting current densities (j) ±5 mA.cm−2 vs. Ag|AgCl|3M KCl) of bare substrates in 0.1 mol.l−1 KNO3 solutions as well as AgAPs’ decorated ones in 0.2 mol.l−1 AcP pH 5.0 are summarized in Table 1.Table 1.

Substrate. FR-4 (or FR4) is a for glass-reinforced epoxy laminate material. FR-4 is made up of several materials which are woven fiber glass cloth with an epoxy resin binder which is flame resistant. "FR" stands for flame retardant, and indicates that the material satisfies with the standard UL94V-0. The designation FR-4 was created by NEMA in 1968. FR-4 glass epoxy is a fashionable and adjustable high-pressure thermoset plastic laminate grade with good quality in weight ratios. Accomplished near zero water absorption, FR-4 is most frequently used as an electrical insulator owns a considerable mechanical strength. The material is known to hang on to its high mechanical values and electrical insulating qualities in both dry and humid conditions. These features, along with good fabrication characteristics, lend being beneficial to this grade for a full extent variety of electrical and mechanical applications.
Substrate. “However, given the fact that little predictive capability exists regarding changes to substrate composition resulting from the Project, and the fact that substrate data were not available, it was assumed that the substrate in the work areas was mostly sand (HSI = 0.5) for both the pre- and post-construction conditions. This assumption was further supported by empirical evidence from previously constructed dike fields within the MMR. Thus the substrate parameter had no influence on the net change to AAHUs in this initial assessment. However, new pre- and post-construction substrate data may become available as data are collected and visual observations are made at planned and completed work sites. Therefore, this assumption may be revisited during future project planning and mitigation assessments, at which time the pre- and post-construction substrate category could be updated for any of the work sites assessed herein, potentially altering the programmatic change in AAHUs.” March 2018 EA at 13 (emphasis added).
