For enlarging cored, punched, or drilled holes, core drills are particularly suited.
Both these cases resulted in a typical donut-shaped growth, where many thin NCs nucleate around the holes' rim leaving the holes core empty, as shown in Figure 1e, f.
If you have a hole in the hollow core, then do the following: defer.add img); Stuff a bunched up paper towel just inside the hole.
The connectors were installed through holes cored in the concrete slabs of the beams.
In August 2000, solid chunks of blue paper from the surface, organic litter from woodland sites, grasses from crop sites, and soils of increasing depth were sampled from ~1 m3 holes cored at the four sites, as shown on Fig. 1 for the woodland site.
Within each site x forest zone (seaward fringing or landward scrub) replicate trees (6 9 replicates) were fertilized either annually or biannually by inserting 200 300 g of urea (nitrogen, N) or triple superphosphate (Phosphorus, P) into 30 cm deep holes cored on either side of the main stem of the tree.
The seedlings were then transferred to holes cored into a Styrofoam lid floating atop a 10L plastic tub filled with 1 mM N nutrient solution (1.0 mM KNO3, 1.5 mM CaCl2, 1.0 mM MgSO4·7H20, 1.0 mM K3PO4·7H20, 0.5 mM NH4Cl; micronutrients and Fe-EDTA as described in Norén et al. 2004; and 0.5 gL-1 MES, pH 5.7).
The coring-type diamond bit makes an annular hole, the core of which provides a sample cross section of the strata penetrated, and is used for prospecting.
1,194, and 1243 m in the Hole B core, which correspond to the fault zones at depths 1,111, 1,153, 1,221 m in the Hole A core, respectively (Hirono et al. 2007a).
As the chip is formed it moves to the inner hole of core drill.
