Byzantine icons of the 14th century in Russian museums are scattered material. In this regard, situation when it is possible to identify or at least raise question whether two such an artistic level from different collections belong same master almost unique. The Late Paleologian icon Resurrection Lazarus Museum can without exaggeration be called pearl collection. was received by 1928 collectio...

Abstract To the best of our knowledge, such a detailed study on polychrome wooden shawabtis King Tutankhamun (18th Dynasty in ancient Egypt) has not been reported literature, so purpose is to noninvasively identify layers and previously applied materials for number that belong through protocol based imaging techniques integrated with single-spot spectroscopic techniques. In first step, (visible...

Few examples of individual polymer-based 3-D printed quasi-optical component types have been previously demonstrated above ca. 100 GHz. This paper presents the characterization components and complete subsystems for applications operating at G-band (140 to 220 GHz). Two low-cost consumer-level printing technologies (vat polymerization fused deposition modeling) are employed, normally associated...

background: up to today, the most complete risk assessment tool for repetitive movements of upper limbs has been the occupational repetitive actions (ocra) method. the index of the analysis is relatively accurate. several risk factors such as repeated motion, force, body condition, additional effective factors and return period can be useful for future preventive measures. the present study eva...

Microfocused X-ray fluorescence imaging was used to examine two 19th century daguerreotypes. The distribution of Hg-bearing nanoparticles beneath the Au gilding layer gives rise to contrast in the photographs. The sum image for Au + Hg M line X-rays is therefore a compositional image that mimics daguerreotype photograph contrast. Because the thickness of the Au and Hg on the surface represents ...

With any great voyage of discovery the explorer should always be asked at the outset “Why are you doing this?” To answer the question “Why use ionic liquids for electrodeposition?” it is first necessary to look at current best practice and find its limitations. It is widely recognised that in 1805 Italian chemist, Luigi Brugnatelli made the first experiments in what we now know as electroplatin...

Abstrak —Perhiasan telah dikenal oleh manusia sejak zaman prasejarah yang terbuat dari batu-batuan maupun tulang hewan. Perhiasan tidak hanya memiliki fungsi estetis, melainkan juga status sosial bagi pemakainya. Seiring dengan berkembangnya peradaban manusia, teknologi pengolahan perhiasan mengalami kemajuan segi pembuatannya salah satunya ditemukannya teknik pengerjaan logam. Salah satu logam...

texture, one of the important elements in visual arts, is produced in different ways. whereas each painting is a multilayered object, any separate layer can have its own distinct texture. texture can be resulted of inherent nature of artist's depicted materials, such as canvas or support, and it can be, also, produced in the ground or paint layers. in addition, by using of different materi...
