Talc‐Tempered Pottery From Bala Hissar, Kabul: An Analytical Study
ABSTRACT Potsherds of cooking ware excavated at Bala Hissar archaeological site in Kabul were studied using X‐ray fluorescence (XRF), scanning electron microscope‐energy dispersive X‐ray spectrometry (SEM‐EDS), Raman spectroscopy, X‐ray powder diffraction (XRPD), thermogravimetric analysis (TGA) and optical microscopy.

Feshbach spectroscopy of an ultracold Rb-Cs mixture [PDF]
This thesis reports the observation of interspecies Feshbach resonances in an ultracold mixture of Rb and Cs atoms. A versatile combined magnetic and optical potential has been designed and constructed which is capable of bringing both $^{87}\rm{Rb}$ and

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 ...

ABSTRACT This paper examines the interaction of two ware traditions in the Maridíaz mortuary assemblage (Pasto, Nariño, Colombia), a rare, well‐documented cemetery context in which Piartal, Tuza, and hybrid vessels co‐occur. Using portable X‐ray fluorescence (n = 39) and 3D geometric morphometrics (n = 25), we find shared ceramic compositions ...

ABSTRACT This study presents a systematically integrated, multiproxy characterisation of Iron Age ceramics from Tyre (Lebanon). Ninety‐nine ceramic samples from stratified Iron Age contexts on Tyre's Acropolis, together with a small Late Bronze Age and raw‐clay reference set, were analysed using petrography, microfossil identification, X‐ray ...

Bond strength enhancement for additively manufactured zirconia: Micro‐retentive design approach
Abstract Purpose To investigate the effect of digitally designed micro‐retention features on the bond strength of additively manufactured (AM) zirconia copings. Materials and Methods Sixty titanium base abutments (NobelParallel, NobelBiocare), pretreated with 50 µm alumina particles were divided into four groups (n = 15 per group); one group with ...
