Archaeometry, EarlyView.ABSTRACT The object of this study consists of an archaeometric investigation of Early medieval Forum Ware glazed ceramics found in the central archaeological area of Rome, a significant chronological and economic marker for 8th–11th centuries. Instrumental analysis included digital microscopy, ESEM‐EDS imaging, EDS spectral analysis, EMPA quantitative ...

EFFECTS OF SOME NATURAL SOIL AMENDMENTS AND WATER REQUIREMENTS ON THE GROWTH AND CHEMICAL CONSTITUENTS OF SOME LAWNS (PASPALUM VAGINATUM, L.) [PDF]
Scientific Journal of Flowers and Ornamental PlantsThe aim of this research was to improve properties of calcareous soil by adding two natural soil conditioners (sand + compost) with different rations, i.e., calcareous, calcareous + composted leaves (3:1 v/v), calcareous + sand (3:1 v/v) and calcareous +

Experimental Study on Mechanical Properties of Mask-Improved Calcareous Sand
Due to the widespread prevalence of respiratory diseases such as COVID-19 and H1N1, the use of disposable masks has increased significantly. Consequently, the environmental issues arising from their accumulation have become increasingly severe.

Effects of particle size on dynamic constitutive relation and energy absorption of calcareous sand
, 2019 The dynamic responses of calcareous sand at high strain rates, closely relating to geotechnical and ocean engineering, are still not fully understood. This paper reports a series of split-Hopkinson pressure bar tests on porous calcareous and solid silica

Archaeometry, EarlyView.ABSTRACT The specific depth‐profiling capabilities of the muonic x‐ray emission spectroscopy (μ‐XES) technique have proved to be effective for examination of the elemental distribution within ancient coins. This ‘layered’ analysis can also be applied to the examination of ancient faience, the production of which can result in distinct layers (glaze ...

Archaeometry, EarlyView.ABSTRACT The materiality of the white pigment motif at the Cloggs Cave rockshelter, near Buchan in GunaiKurnai Country (southeastern Australia), contains details about the cultural and environmental contexts in which the art was created and preserved. Here, we (1) present physicochemical analyses of the pigment composition; (2) explore implications for

Connected inner pore analysis of calcareous sands using SEM
Yantu gongcheng xuebao, 2017 Calcareous sand is a special kind of geotechnical sand which consists of much carbonate. Based on the remains of the original marine organisms, the calcareous sand grains have irregular shapes and contain inner pores.

Archaeometry, EarlyView.ABSTRACT Chert tools were widely used in prehistory by human societies due to their knapping suitability and availability, but their relatively uniform composition, especially in evaporitic cherts, complicates sourcing, requiring specialised analytical methods.
