Although scanning electron microscopy has a great potential in biological application, there are certain limitations in visualization of the biological structure. Satisfactory techniques to demonstrate natural surfaces of the tissue and the cell have been reported by several investigators. However, it is commonly found that the surface cell membrane is covered with a minute amount of mucin, secretory substance or tissue fluid as physiological, pathological or artefactual condition. These substances give a false surface appearance, especially when the tissue is fixed with strong fixatives. It seems important to remove these coating substances from the surface of the cell for demonstration of the true structure.

Political Relationships

Regions play an important part in scholarly discussions on Hellenistic Central Asia. Most commonly the concept of regions is determined by historically testified administrative entities. They also form the basis for many art-historical and archaeological considerations which seek to define specific regional characteristics. At the same time, such qualities are often used to define regional boundaries or elucidate political relationships. Taking the perspective of ceramic evidence, we highlight the complexities of interpreting pottery assemblages with regard to regional identities and inter-regional variations. Examining the different properties of ceramics, including their form, surface appearance and decoration, we demonstrate how changeable the notion of ‘region’ can be in this context. Distinct criteria and even minor chronological variations lead to the description of different regions, showing that we should use such definitions with care.

The Mediterranean Basin

The water resources crisis facing countries of the Mediterranean Basin is reflected, in diminished form, in the semi-arid, “Mediterranean-climate” zone of Australia. Some creative solutions involving the collection, treatment, storage, retrieval and use of storm runoff to replace the component of mainssupplied water presently used for “second quality” purposes, are emerging in Adelaide, capital city of South Australia. The paper describes one initiative being taken to achieve source control of stormwater – quantity and quality – in mixed-density residential streets. The resulting streetscape is suitable for use in both “greenfields” and re-development projects. The paper explores the hydrological/hydraulic performance of the system and shows that it satisfies all theoretical- requirements for safety in the full range of flooding up to and including the “once in 100-years” event. The new streetscape holds the following advantages over conventional streetscapes : reduced peak outflows, greatly improved effluent water quality, aids “greening” of the landscape, potential for aquifer recharge where appropriate, aquiferretrieved groundwater can replace mains water used for irrigation, “nuisance” flows are fully contained (no surface appearance), major flows only occupy the swale, street residences are less flood prone and the streetscape fits more harmoniously into undulating terrain.
