Gland plate Three to four mm of MS or non-magnetic material, depending upon the number, sizes and type of cables (single core or multicore) it has to carry (Figure 13.33).

A single or multicored plastic-coated cable of the type NYY or NYY-O is used as the connecting cable between a protected object and an anode in soils and fresh water, and particularly in seawater, medium heavy or heavy rubber-sheathed connections of an NSHou or NSSHou type are used. Heavy welded connections of type NSLFSou are used for severe mechanical loading. In addition to these, for ships, marine cable of type MGCG or watertight cables must be considered. 

The header cable between anode bed and rectifier must be particularly well insulated. For this reason cables with double plastic sheathing of type NYY-O are used. The cable sheath must not be damaged during installation because the copper core at the defects will be anodically attacked in a very short time and the connection to the rectifier broken. Damage to the cable sheath is not so serious if a multicored cable is used. Usually not all the core insulation is damaged so that the operation of the anode bed is not interrupted. In addition, measurement of resistance and detection of defects is easier.

The devices used for sampling of solid samples (sludge, sediment, and soil) are usually grab samplers or corers. Box corers or multicorers can be employed if more detailed information on the spatial distribution of the analytes is needed. The samples are stored in the dark at 4 °C or more commonly at -20 °C, preferably in glass containers [53]. Very often, solid samples are also dried or lyophilized prior to storage.

Some patients exhibit cores that are smaller and shorter (longitudinally) than the cores observed in central core disease and that occur both in slow and fast type muscle fibers (Ferreiro 2002b Robinson 2006). These cores are referred to as multicores or minicores and patients with myopathic symptoms (e.g. proximal muscle weakness, delayed motor development, difficulty rising, etc.) along with these corelike structures are said to have multiminicore disease (MmD). Considerable overlap...

Animals are placed individually on a stationary treadmill (30 x 10 cm) and are connected to a signal conditioning system (Coulboum Instruments, Allentown, PA 18106, USA, Model V75-01) via a shielded multicore cable, connected at one end to the plug on the animal s head and at the other end to a swivel mounted 30 cm above the center of the treadmill. Animals are then given a 60 minute session with alternating periods of 10 minutes with the treadmill turned on (speed 1.5 rn/rnin) and off. 

In classic intrinsically safe instrumentation multicore cables lead from the control room into the explosion protected system. Several sensors/actuators are wired to a terminal box and connected to the multicore cable.

A separate chapter of standard EN 50039 is dedicated to cables in an intrinsically safe system. Special requirements for multicore cables with several intrinsically safe circuits are listed as well as the faults to be assumed between intrinsically safe circuits (wire breaks and short-circuits) if these requirements are not met. In the meantime, these requirements form a part of standards EN 60079-14 and IEC 60079-14 respectively (see Section 6.9.5).

As indicated in Fig. 1. lb, the individual matchers may either be executed sequentially, independently (in parallel), or in some mixed fashion. In the sequential approach, the matchers are not executed independently, but the results of initial matchers are used as input by subsequent matchers. A common strategy, e.g., used in Cupid (Madhavan et al. 2001), is to first execute a linguistic matcher to compare the names of schema elements and then use the obtained similarities as input for structure-based matching. In the parallel matcher strategy, individual matchers are autonomous and can be independently executed from other matchers. This supports a high flexibility to select matchers for execution and combination. Furthermore, these matchers may also physically be executed in parallel, e.g., on multicore or multiserver hardware. On the other hand, the autonomy of individual matchers may introduce redundant computations, e.g., of name similarities to be used for structural matching. The mixed strategy combines sequential and parallel matcher execution and is thus most complex.

Fig. 3.12 In situ measured oxygen profile (dots, Holby and Riess 1996). In addition, an oxygen profile which was also measured ex situ with a micro-electrode is shown (circles, Enneking et al. 1996). The sample was obtained with a multicorer tube. Both profiles were measured in the course of the Meteor M 34/2 expedition at the same time and from the same location in an upwelling area off Namibia, at a depth of approx. 1,300 m below sea level.

At least the upper 10 to 30 cm of the core length obtained with either tool is usually adulterated in that it is not appropriate for pore water analysis. The multicorer, high-momentum gravity corer, or at least the box corer should be employed in a parallel procedure to ensure that this layer will also be included as part of the sample. It should not be overlooked that, especially in the deep sea, sampling with two different tools at the same site might imply a distance of several 100 m on the ocean floor. From this deviation considerable differences in pore water composition, and in some of the biogeochemical reactions close to sediment surface, are likely to result. Hence the specification as to same site must be acknowledged with caution.
