The happiest teacher should have married ‘three wives’, namely: teaching, research and social service. I did so for the sake of mangroves: sites of ecological wonder and scenic splendor. Boat rides through the sun-dappled waterways in the mangrove forests attracted me. The breath-taking beauty of the coastal forest, with its arching roots, breathing roots, salt-vomiting leaves and ‘mud dancing’...

Previously, Thioploca ingrica had not been grown in the laboratory and observation of the organism was limited to specimens taken directly from natural mud samples. The method described here makes laboratory cultivation of T. ingrica in mixed culture possible. The medium consists of low concentrations of extracted hay, water, and mud with its natural bacterial flora. Four weeks after the hay an...

One had to be quick. Walk like a stork. Easier said than done, carrying a backpack full of equipment, buckets full of samples and a shovel over the shoulder, sinking knee-deep into the mud under the scorching tropical sun and watching out for crocodiles. I looked like a pig already. What was I doing here? Growing up near the coast of the North Sea, harbouring the Wadden Sea being one of the mos...

Abstract The eruption of mud and magma can be influenced by earthquakes reports date back more than 2000 years. Dozens examples eruptions have now been documented in response to both static dynamic stresses from earthquakes. Already erupting systems are most sensitive compared initiating new eruptions. Multiple plausible mechanisms proposed for triggering including disrupting particle-rich mate...

The stability of a viscoplastic fluid film falling down an inclined plane is explored, with the aim of determining the critical Reynolds number for the onset of roll waves. The Herschel–Bulkley constitutive law is adopted and the fluid is assumed two-dimensional and incompressible. The linear stability problem is described for an equilibrium in the form of a uniform sheet flow, when perturbed b...

The Mediterranean Sea constitutes a unique environment to study cold-seep ecosystems due to the presence of different geodynamic settings, from an active margin along the Mediterranean Ridge (MR) to a passive margin in the Nile Deep-Sea Fan (NDSF). We attempted to identify the structure of benthic communities associated with the Napoli and Amsterdam mud volcanoes (MVs) located on the MR and to ...

In this paper, we propose a novel low complexity minimum mean-squared based multiuser detection (MMSE MUD), which employs partial but essential information of the interferences, in a multichannel TDMA system. The new approach begins with the determination of the effective channel length of the interferences based on the information theoretic criteria. We then truncate the channel taps according...

drilling fluid is the most important lifeline of the drilling operation, that main task is facilitate the cuttings removal of the drilling. there are varieties of drilling fluids such as sodium bentonite based-drilling fluid is called “mud” and drilling foam or surfactant based-drilling fluid is called “soap”. the present work aims are study on the modified drilling mud properties by using the ...
