Since the 1940s, when maritime archaeology was established, systematic excavation of submerged wrecks began to be refined. Systematic excavations led recovery a vast array organic and inorganic artefacts, including human non-human bones teeth. In order preserve materials recovered from sea, discipline conservation rapidly expanded dealt with unique issues, including, but not limited to, marine ...

The Holocene Wolfenden tufa deposit in south-eastern British Columbia, western Canada, preserves a unique record of the earliest stages calcium carbonate deposition resulting from microbial extracellular polymeric substances-mediated precipitation amorphous (ACC) with partial transformation to monohydrocalcite (MHC) and subsequently nanocrystalline calcite. This is first documentation mineralog...

• Intrinsic self-healing mechanism after contact with water. Multiple healings at the same damaged area. Controlled electrical characteristics. Mechanically resistant and hydrophobic coating. materials have received significant attention due to characteristic recovery damage properties through reversible dynamic covalent non-covalent interactions. Furthermore, functional reliable mechanical are...

Abstract This study aims at determining the state of government provided boreholes, evaluating groundwater potential and quality assessment within Ayede Ekiti community. 12 Vertical Electrical Soundings (VES) were conducted using Schlumberger array in order to determine geoelectric layers fracture attributes. Also, water samples collected from area evaluate physicochemical characteristics groun...

The large number of historic metal-hulled shipwrecks on the seabed is a major consideration for marine environment, heritage management and spatial planning. Their stability driven by linked hydro- sediment-dynamics, which in turn influence chemical corrosion biological encrustation. dynamism at underwater sites frequently expressed elaborate patterns depositional erosional features developed d...

Palaeonitella trifurcata n. sp. is a minute ecorticate thallus of charophyte from non-marine upper Barremian–Lower Aptian section the Garraf Massif, near Barcelona (Catalonia, Spain). Whorls trifurcated branchlets built glomerules about 1 mm across. Small radial were once in three terminal acuminate dactyls. Longer and more robust branches, two per whorl emerge basal trifurcation, bore opposite...
