Successful mining of deep sea deposits strongly depends on the proper choice of the right equipment. The most probable concept for a deep sea mining system would consist of the three major sub-components: Seafloor Mining Tool, Vertical Transport System and Mining Support Vessel. In this paper, emphasis is placed on the Vertical Transport System. We analyse the pros and cons of the different concepts such as hydraulic transport using centrifugal or positive-displacement slurry pumps, conventional and unconventional airlift systems, vertical offshore mining systems and vortex slurry transportation systems. All these systems are considered for their applicability at different water depths (from the relatively shallow to the relatively deep) for the different types of materials (from the relatively fine to the relatively coarse) and various production rates in terms of the efficiency, reliability and state of the art of technology.

The escal light gland of three different-sized specimens of the deep-sea anglerfish Haplophryne mollis (family Linophrynidae) has been examined by light and electron microscopy. The light gland has a central cavity, with diverging branched ducts which ramify into numerous tightly-packed radial tubules. In the two largest specimens all glandular lumina contain symbiotic bacteria. Except for a thin-walled part of the typical radiating tubules, the epithelial walls of the light gland are of a uniform structure, consisting of flattened basal cells, situated next to the basal lamina, and tall cells extending to the lumen.In the smallest specimen examined the various parts of the light gland were not fully differentiated and only a very few symbiotic bacteria were present; its glandular epithelium differed from that of the two larger specimens by containing many goblet cells, the secretion of which may be important for the initial establishment of the right strain of symbiotic bacteriaObservations on the luminescence of live specimens have shown that the light emission can be rapidly modulated from within the esca. The in vivo flash kinetics are considerably slower than those of Dolopichthys longicornis, but similar to those of both the caruncle exudate of Ceratias holboelli and in vitro anglerfish bacterial luciferase.

‘New frontiers’ considers where the future lies for tidal studies. On our own planet there are discoveries to be made in difficult-to-reach places such as deep-sea ecosystems. The interaction between tides and sunlight in shallow water has been barely explored. Innovative computer models allow us to reproduce the tide in the early ocean. Tidal forces are not confined to Earth. Tidal flexing of the icy moons of Jupiter appears to have created a liquid water ocean on Europa. It is possible that this ocean has the right conditions for life, and space probes planned for the next few years will be able to test this possibility.

Humans love to eat fish, but we must be careful not to catch too many. To make the right rules about how many fish can be caught without decreasing the population too much, it is helpful to know how many fish are in the sea. It is difficult for scientists to go underwater to count fish, but technology can help. Animals like dolphins can use sound to “see” the world around them. Just like dolphins, scientists can send a sound into the ocean and measure the echo that comes back. They can even use the unique echoes of fish to get an idea of how many fish are in the sea. Scientists are now testing whether this technology can help them to explore the deep sea. While it is not always easy to see with sound, the challenges we face and the mistakes we make often lead to new discoveries!

SummaryRecently, there has been a proliferation of international agreements imposing minimum standards on states in respect of their treatment of foreign investors and allowing investors to initiate dispute settlement proceedings where a state violates these standards. Of greatest significance to Canada is Chapter 11 of the North American Free Trade Agreement, which provides both standards for state behaviour and the right to initiate binding arbitration. Since 1996, four cases have been brought under Chapter 11. This note describes the Chapter 11 process and suggests some of the issues that may arise as it is increasingly resorted to by investors.

Abstract The target article carefully describes the memory system, centered on the temporal lobe that builds specific memory traces. It does not, however, mention the laterality effects that exist within this system. This commentary briefly surveys evidence showing that clear asymmetries exist within the temporal lobe structures subserving the core system and that the right temporal structures mainly underpin face familiarity feelings.

It is well known that for reflections corresponding to large interplanar spacings (i.e., sin θ/λ small), the electron scattering amplitude, f, is sensitive to the ionicity and to the charge distribution around the atoms. We have used this in order to obtain information about the charge distribution in FeTi, which is a candidate for storage of hydrogen. Our goal is to study the changes in electron distribution in the presence of hydrogen, and also the ionicity of hydrogen in metals, but so far our study has been limited to pure FeTi. FeTi has the CsCl structure and thus Fe and Ti scatter with a phase difference of π into the 100-ref lections. Because Fe (Z = 26) is higher in the periodic system than Ti (Z = 22), an immediate “guess” would be that Fe has a larger scattering amplitude than Ti. However, relativistic Hartree-Fock calculations show that the opposite is the case for the 100-reflection. An explanation for this may be sought in the stronger localization of the d-electrons of the first row transition elements when moving to the right in the periodic table. The tabulated difference between fTi (100) and ffe (100) is small, however, and based on the values of the scattering amplitude for isolated atoms, the kinematical intensity of the 100-reflection is only 5.10-4 of the intensity of the 200-reflection.

A redesigned specimen holder and cap have made possible the freeze-etching of both fracture surfaces of a frozen fractured specimen. In principal, the procedure involves freezing a specimen between two specimen holders (as shown in A, Fig. 1, and the left side of Fig. 2). The aluminum specimen holders and brass cap are constructed so that the upper specimen holder can be forced loose, turned over, and pressed down firmly against the specimen stage to a position represented by B, Fig. 1, and the right side of Fig. 2.
