    Notes: Coastal wetlands are an important natural resource, providing habitat for fish and wildlife, particularly many rare or endangered species. These wetlands also serve important functions for the treatment of urban runoff and effluent discharges, the dissipation of wave energy, and shore protection. The US Fish and Wildlife Service estimates that approximately 45 000 km2 of US wetlands have been destroyed in the past two centuries.The importance of wetlands in the ecosystem has only begun to be understood during the past two decades, and there has been a major legislative effort to preserve, protect, and enhance existing coastal wetlands. The productivity of tidal wetlands is related directly to the hydrologic characteristics of the system, and some considerations for the hydrologic design for the enhancement or construction of tidal wetlands are outlined. Recent attention has focused on the use of dredged spoil materials from harbours or shippping channels to restore historic tidal wetlands. The hydrologic design criteria are illustrated through a series of case studies in California.

    Notes: The use of automated equipment for monitoring water quality is a concept which has received considerable impetus since the Water Act 1989 was introduced. This paper reports on two initiatives by the National Rivers Authority to develop systems for use in their role as the guardians of the water environment. Portable systems have been developed for detection of episodic pollution events and instantaneous spot measurement of water quality.This paper outlines the principal activities of the development of the systems and their use.

    Notes: The paper reviews the pollutant emissions from the incineration of waste. The emissions to the atmosphere are discussed in detail in terms of odour, dust and litter, particulate metals and salts, and chlorine, fluorine, sulphur and nitrogen compounds. The products of incomplete combustion of waste are reviewed with particular emphasis on polycyclic aromatic compounds, dioxins and furans. The pollution arising from contaminated wastewater and ash is discussed. The sampling and analysis of the pollution emissions are also reviewed.

    Notes: SUMMARY. A simple 4π light collector is described suitable for light attenuation studies. It uses table tennis balls as light collectors and its spherical response is near to ideal. A circuit for a simple meter based on an operational amplifier is given as well as that for a direct-reading log-ratio meter. Both circuits are intended for use with selenium photocells. The cost of the materials for detector and simple meter is less than £30.

    Notes: The structure, microstructure and petrology of a small area close to the village of Bard in Val d'Aosta (Italy) has been studied in detail. The area lies across the contact between the Gneiss Minuti (GM) and the Eclogitic Micaschist (EMS) Complexes of the Lower element of the Sesia portion of the Sesia-Lanzo Zone (Western Alps). Both complexes have undergone high-pressure metamorphism, but the metamorphic assemblages indicate a sudden increase in pressure in going across the contact from the GM to the EMS. Therefore, we interpret the contact as a thrust dividing the lower element of the Sesia into two sub-elements. This interpretation is supported by structural evidence.The early Alpine (90-70 Ma) metamorphic history is best preserved in the EMS and is one of increasing pressure associated with thrusting. The maximum P/T recorded in the EMS is 〉1500 MPa (〉15kbar) and 550°C and in the GM is 〈 1500-1300 MPa (〈 15-13 kbar) and 500-550°C. We suggest that the rocks were probably in an active Benioff zone during this time.From then on the histories of the GM and EMS are the same. Deformation continued and the thrust and thrust slices were folded during decreasing pressure. We interpret the first postthrusting deformation in terms of uplift associated with continued shortening of the crust and underplating after the Benioff zone had become inactive and a new Benioff zone had developed further to the north-west.A still later deformation and the Lepontine metamorphism (38 Ma) are related to continued uplift. Much of this deformation is characterized by structures indicative of vertical shortening and lateral spreading as the mountains rose above the general level of the surface.

    Notes: A field experiment compared the effects of sheep, deer and cattle dung on pasture growth and soil nutrient status. Sheep and deer dung pellets degraded rapidly within three to eight weeks, while it was 12 months before all visible cattle dung had gone from the soil surface. The cattle dung initially reduced herbage yield owing to smothering. However, after 40 days, herbage around the edges of the dung patch responded positively to the dung and more dry matter was produced in this patch than in the control patch during the first 12 months. There was no measurable herbage response to sheep dung, but deer dung significantly increased herbage production. While the rate of nutrient application per unit area was similar for sheep and deer dung, the latter was more evenly spread within the patch area. Consequently, a greater percentage of pasture plants in the patch received nutrient additions from the deer dung and a measurable response was recorded. Twelve months after dung application, soil nitrate, phosphate and organic C were higher in dung patches than in the control patches. In cattle dung patches, this response was accompanied by higher microbial biomass C levels, arylsulphatase and arylphosphatase activities. Some residual effect on organic C levels was still evident three years after cattle dung application.

    Notes: Acinetobacter calcoaceticus RJE74 contains a large transmissible catabolic plasmid, pWW174, of about 200 kb, which encodes its ability to grow on benzene (Bzn+). pWW174 was unstable in Acinetobacter hosts and was lost at high frequency in the absence of selection for Bzn*. The catabolic pathway appeared to be via benzene cis-glycol, catechol and the β-ketoadipate (ortho) pathway. pWW174 encodes a catechol 1,2-oxygenase which is significantly more thermolabile than the chromosomally determined enzyme. pWW174 was able to complement all cat mutants (catechol to central metabolites) of A. calcoaceticus ADP1 (BD413) tested. Two regions of the plasmid were cloned, one carrying catA, the gene for catechol 1,2-oxygenase, and another carrying catBCDE, the subsequent four enzymes of the β-ketoadipate pathway: these two regions appeared to be separated by at least 10 kbp. Hybridization indicated homology between the plasmid cat genes and the corresponding chromosomal genes of ADPL.

    Notes: The protein kinase C (PKC) family comprises calcium- and phospholipid-dependent kinases whose activity is stimulated by diacylglycerol and tumour-promoting phorbol esters such as 12-tetradecanoyl phorbol-13-acetate (TPA). In the Gram-negative bacterium Escherichia coli, functional similarity to PKC was demonstrated in crude extracts by calcium and phospholipid-dependent, TPA-stimulated phosphorylation of a small number of endogenous substrates. Activity was reduced by sphingosine, a known inhibitor of eukaryotic PKC. Structural similarity to PKC was demonstrated in crude and partially purified bacterial extracts by cross-reactivity with several monoclonal antibodies. This revealed isozyme-specific homology between a protein(s) of relative molecular mass 80–85000 in E. coli and the α-and γ-isozymes, but probably not the β-isozyme, of eukaryotic PKC.
