Typical marine propellers are fixed pitch and small in diameter with veiy thin, but broad, blade sections. They are made from either cast metal, corrosion-resistant metal alloys such as copper, or composite materials. Marine propellers normally operate at 60 percent efficiency due to the proximity of the ship s hull, which limits the overall diameter of the propeller and disturbs the efficient flow of water through the blades. As a result, the blades have to be veiy wide to produce adequate thrust. Marine propeller designers use innovations such as overlapping blades and wheel vanes to offset those problems and improve efficiency.

A continuous polymer anode system has been developed specifically for the cathodic protection of buried pipelines and tanks. The anode, marketed under the trade name Anodeflex , consists of a continuous stranded copper conductor (6AWG) which is encased in a thick jacket of carbon-loaded polymer, overall diameter 12-5 mm. To prevent unintentional short circuits an insulating braid is sometimes applied to the outer surface of the conductive polymer.

In the manufacture of fast cord the first process is to coat paper or textile yarns with a blackpowder/nitrocellulose dope by a dipping process. These yarns are thoroughly dried and a number of them passed through an extruder and given a thick covering of plastic incendiary composition. The cord thus produced is covered with a protective layer of plastic, usually polyethylene. The overall diameter of the cord is about 2-5 mm. 

The production of Ag Carbon nanocables was reported by Yu et al. [20]. In this case the authors used the hydrothermal carbonization of starch in the presence of Ag N03 leading to the one-step formation of carbon/Ag hybrid nanocables. Such silver-carbon nanocables can have a length as long as 10 mm and overall diameters of 1 micron with a 200-250 nm silver lining. When made at higher concentrations, they tend to fuse with each other (Fig. 7.5(a) and (b)). This method was extended to a polyvinyl alcohol(PVA)-assisted synthesis of flexible noble metal (Ag, Cu) carbon composite microcables [21]. 

Morphology of Si-Based Nanowires. The overall diameters of SiNW produced so far range from 3 nm to 100 nm, and many methods have yielded a frequently occurring diameter of 15 nm when they are made between the temperature of 1100 and 1200°C. This size of nanowires, as speculated at the end of this chapter, may be determined by the selected growth temperature.

The box used was of polished aluminium and could be fitted with one of three lids with holes 0.0568,1.068 and 1.250 mm- diam. respectively. The overall diameter of the box was 0.370 in. and height 0.375 in., and its weight almost exactly 1 g. 

Portion of an endocytic vacuole forming in the plasma membrane of a cultured fibroblast. The view is from the inside of the cell and shows a large clathrin cage assembling to form a coated vesicle. The overall diameter of the vacuole is 0.2 pm. Clathrin cages vary in size and in the number of faces but are typically 0.1 pm in diameter (see Fig. 8-27 and associated references).

To diminish this problem, a capillary with a sharp tip is used [8], which may be prepared by drawing out a normal capillary. To overcome the shielding effect significantly, the overall diameter of the capillary at its end should be considerably smaller than the mean diameter of the mercury drop. It should, however, be mentioned that work with this type of capillary is more difficult, and the production of such capillaries with a uniform drop time requires considerable practice. 

Ultimately, the speed of a filling machine is a function of the engineering limits of metal machinability. The valves are mounted on a ring that has to be machined to very tight tolerances and mounted such that it rotates evenly, hence the overall diameter of a filler has a maximum value and so the number of valves that can be mounted on the pitch circle has a maximum. 

The term hard-core RMs is used to describe dispersions containing an excess of colloidal carbonate over that required to neutralize the sulfonic acid. The excess is found in calcium carbonate trapped in a micellar structure. The total base number (TBN) of the additive so obtained is 368 mg KOH/g of oil. The crude additive consisted of 33 wt% CaC03 (Delfort et al., 1995 Giasson et al., 1992). Some typical results of the core particle with the overall diameter and the detergent layer thickness are shown in Table 3.6 (Marsh, 1987). 

Mitochondria are about the size of bacteria. They have a diameter of 0.2 to 0.5 gm and are 0.5 to 7 p.m long. They are bounded by two lipid bilayers, the inner one being highly folded. These folds are called cristae. The innermost space of the mitochondrion is called the matrix. They have their own DNA in the form of at least one copy of a circular double helix (Chap. 7), about 5 p.m in overall diameter it differs from nuclear DNA in its density and denaturation temperature by virtue of being richer in guanosine and cytosine (Chap. 7). The different density from nuclear DNA allows its separation by isopycnic centrifugation. Mitochondria also have their own type of ribosomes that differ from those in the cytoplasm but are similar to those of bacteria. 

The typical constitution of an optical fiber is shown in Figure 5. Determined by the initial preform geometry, the core diameter is a few micrometers while the cladding is 125 pm. The overall diameter for coated fibers is around 250 pm. With core diameters of the order of magnitude of the propagating wavelength, only the fundamental mode is... 

A high-resolution X-ray diffraction structure of bacterial ferritin is not yet available but it is clear from molecular weight measurements, sedimentation velocities, and low-resolution X-ray data that bacterial ferritin consists of 24 subunits of molecular weight 18,000-21,000, depending on the source 63). The overall diameter of . coli bacfer is 119-128 A, consistent with this protein having the same general shape as animal ferritin.
