Radioactivity monitoring in the marine environment was imposed by the increasing development of nuclear energetics and its world-wide use in many different activities [1]. Both natural and artificial radioactivity play an important role in marine ecology and human health; in this respect three major facts continue to prevail in Romania: the fallout, the presence of the Danube river, and the fut...

The article summarizes some aspects of the current state wind energy and outlines possible development prospects. Attention is focused on requirements Directive 2001/80/EC European Parliament Council EU "On integrated pollution prevention control" 2010/75/EC industrial emissions (integrated control pollution) compliance with these conditions policy Ukraine . considered, as a significant factor ...

The current is not “shielded” from the external electric field, and does not correspond to the current in either a resistive or superconducting wire. The definition (1) was suggested by Daniel Vanzella. See also [1]. The expression (2) is not gauge invariant. However, we will only be concerned with comparison of energies of charges at two different potentials. For additional remarks on eq. (2),...

It is often claimed that marine renewable energy alone could meet the electricity demand of current and future human societies. However, such claims are based on highly uncertain estimations global potentials sources (including tidal, ocean currents, wave, offshore wind salinity thermal gradients), do not take into account embedded technologies. To better understand effective potential energy, ...

Filamentous fungi are well known for their capability of producing antibiotic natural products. Recent studies have demonstrated the potential of antimicrobials with vast chemodiversity from marine fungi. Development of such natural products into lead compounds requires sustainable supply. Marine biotechnology can significantly contribute to the production of new antibiotics at various levels o...

Marine organisms comprise approximately a half of the total biodiversity, thus offering a vast source to discover useful therapeutics. In recent years, a significant number of novel metabolites with potent pharmacological properties have been discovered from the marine organisms. Although, there are only few marine derived products currently in the market, several marine natural products are no...

Petroleum hydrocarbons are important energy resources used by industry and in our daily life, whose production contributes highly to environmental pollution. To control such risk, bioremediation constitutes an environmentally friendly alternative technology that has been established and applied. It constitutes the primary mechanism for the elimination of hydrocarbons from contaminated sites by ...
