Radioactive tracers have a distinct advantage in tracing contaminant migration in natural systems and characterising contaminant mobility and uptake into living organisms in already-contaminated environments or at trace (environmental) levels. To use the contaminant itself in its non-radioactive form, concentrations significantly higher than the normal contaminated background level are...

Siltation in harbour is a lonstanding problem which could generate important costs for maintenance program to secure nautical conditions. This paper reports different studies on sediments in France (Le Havre, Bordeaux, Saint-Michel and Fort-de-France) aiming to characterise the rheological properties of sediment, analyse sedimentation-consolidation processes and propose a numerical model for...

Maintenance of adequate draft in navigation channel for movement of ships from the sea to the port is a serious concern for port authorities. Available draft gets reduced in course of time due to silt deposition on the channel bed and one has to resort to maintenance dredging which is quite an expensive work. The problem of silt deposition is particularly critical for riverine ports like...

Technetium $^{99m}$Tc is, nowadays, the most
applied radioisotope in nuclear medicine, whose use began in the
mid-1960s. Features such as emission of $\gamma$-radiation of low energy
($140$ keV) with very good imaging properties, half-life
$\tau_{1/2}=6.02$ h, and production via relatively long-lived
generators, facilitating their supply and use in locations far
from manufacturing sites,...

There is a continuous sedimentation in harbour basins and access channels. Therefore maintenance dredging is necessary.
The depth necessary for sailing includes the free space between the keel and the bed of the channel called keel-clearance .
Tests on physical models indicated that free movement of ships in the harbour is possible upto silt density 1.2 g/cm3. The layer of fluid mud...

This paper describes the construction of a new compartmental fractional model for water renewal in Montevideo’s Bay that improves a conventional two compartments model [1]. The validity of the fractional kinetic model and its practical applicability are discussed. The available evidence suggests that the highly polluted Montevideo’s bay operates as an intermittent tidal pump that injects...
