The chances of humans discovering life on another planet are extremely low, a British scientist claims. Professor Andrew Watson of the University of East Anglia has calculated that there's a chance of less than 0.01% that the right set of

Desalination of seawater has become an important and growing industry due to the water shortage in some Mediterranean countries. This activity may result in environmental impacts, mainly generated by the discharge into the sea of the concentrate (brine) produced. Data

Analysis of deep-sea sediments presents a number of exceptional challenges. Generally, the amount of material available is small and has to be shared among investigators. Also, deep-sea sediment contains a diverse range of components from a variety of sources including

Analyses of aeolian sediments present two main challenges: (1) when aerosol particles are collected on atmospheric filters, only a small amount of aeolian material is normally present, and (2) in these and other samples, the aeolian sediment is typically mixed

It is well known that the hydrodynamics of the Venice Lagoon is strongly dependent upon both tides and prevalent wind regimes, namely the Sirocco and the local wind Bora. However, while the effect of the Sirocco on the sea level

Analysis of Istrian shellfish breeding areas for (Diarrhetic Shellfish Poisoning; DSP) shellfish toxicity were recorded in summer and autumn 2005 as part of Croatian shellfish breeding areas monitoring programme. As well as analysis of Paralytic Shellfish Poisoning (PSP), DSP and

Protection of ships hulls against biofouling has been a problem since man began sailing the seas. The most common protections are specially produced antifouling paints. These paints could be broadly classified in three main groups, or generations, depending on the

A simple and low-cost method for monitoring macroalgal standing crops in shallow water consists of flying over and photographing the areas in an ultralight aircraft to determine the surface area of macroalgal mats. In the proposed method, photos are analysed

In spring 2003, the pH, redox potential (Eh), grain-size (G), Total Nitrogen (TN), Total Phosphorus (TP) and Total Organic Carbon (TOC) were measured in superficial sediment samples from 83 sampling stations equally and randomly distributed inside the Orbetello lagoon. Localisation

The general increase in eutrophication of waters and the changes in global climatic conditions have caused over the last 30 years the spread of algal blooms in seas all over the world. The paper describes the different aspects of this

This paper describes the application of the specific Time Series Analysis techniques (TSA), Autocorrelation analysis (AC), Crosscorrelation analysis (CC) and Power Spectral Density (PSD) to elaborate a large set of oceanographic data, such as marine pressure, flow and current. The

The rate of growth or decline in Gross Domestic Product (GDP) is reported quarterly in New Zealand and regarded as the paramount measure of how the nation is faring. However, the welfare of New Zealanders is determined by more than

Rivers are important freshwater resources for many countries and human beings around the world. Social well being, economics and political development have been largely related to the availability and distribution of these freshwater resources. In many parts of the world

Photocatalytic degradation of Methyl Ethyl Ketone (MEK) was carried out in gas phase using TiO2 supported on different adsorbents. Based on size and surface area, three different adsorbents, montmorillonite, -zeolite and MCM-41 were tested. A fluidised bed annular photoreactor fitted

The Genuine Progress Indicator (GPI) is estimated as if nations operate within a closed economy. Therefore, in terms of coverage, the GPI is most analogous to Gross Domestic Product (GDP). Indeed, within the relevant literature, these two indicators are most

The compilation of the Index of Sustainable Economic Welfare (ISEW) requires a large amount of data on a wide range of topics. Gathering these data is a very difficult task that has undoubtedly put off researchers in the past. First,

In the tradition of Hicks (1946), Gross Domestic Product (GDP) is an inadequate measure of national income insofar as it includes, as current income, the depletion of income-generating capital. Using an alternative measure of Hicksian national income called Sustainable Net

The closely related Genuine Progress Indicator (GPI) and Index of Sustainable Economic Welfare (ISEW) provide monetised estimates of societal well-being based on economic, social and environmental criteria. Although the first ISEW/GPI estimates were completed at the national scale, there has

This paper contains a critical assessment of the use of the Fisherian income concept to underpin the Genuine Progress Indicator (GPI) and related measures. Comparisons in the recent GPI literature between Hicksian and Fisherian concepts of income are shown to

The aerobic photocatalytic degradation of municipal dump-site leachate at 300 K has been carried out in a pilot-scale bubble column reactor. The leachate feed is a complex mixture of various organics and nitrogenous compounds. Runs were performed over a 48-hour
