Plasmon-exciton coupling of monolayer MoS2-Ag nanoparticles hybrids for surface catalytic reaction

The optical properties of monolayer molybdenum disulfide (MoS2)/Ag nanoparticle (NP) hybrids and their application to surface catalytic reactions were studied by transmission, photoluminescence (PL) and Raman spectroscopies. The local surface plasmon resonance (LSPR) of Ag nanoparticles was tuned to better match the exciton energy of monolayer MoS2. The PL of the hybrids was enhanced by more than

Anguiform graffiti in the Roman quarries at Gebel el Silsila

The current issue of Journal of Intercultural and Interdisciplinary Archaeology is mainly dedicated to the various aspects of Renenutet/Isis Thermouthis, but also snake-like deities, their iconography and associated apotropaia. This paper will explore three main topics associated with this topic within the sandstone quarry of Gebel el Silsila: 1) Graeco-Roman anguiform pictorial representations, 2

From Epipalaeolithic petroglyphs to Roman graffiti : Stylistic variability of anthropomorphs at Gebel el Silsila (Upper Egypt)

Gebel el-Silsila displays an astounding concentration of incised illustrations, of which anthropomorphic figures are frequent motifs. These figures were produced over several millennia; from prehistoric petroglyphs to pictorial graffiti of dynastic periods and throughout into Roman days. Spanning over six millennia visitors to Gebel el Silsila depicted huntsmen, warriors, boatmen, and horsemen, reGebel el Silsila displays an astounding concentration of incised illustrations, of which anthropomorphic figures are frequent motifs.

Gebel el Silsila : Field report from the Main Quarry

The Gebel el Silsila Project is a multi-disciplinary Swedish mission dedicated to the study of the archaeological remains at Ancient Egypt’s largest sandstone quarry of Gebel el Silsila, Mountain of Chain, just north of Kom Ombo in the Aswan region.

Pictorial representations at Gebel el Silsila : A 10 000 year long repertoire

Gebel el-Silsila (Mountain of Chain) is located between Kom Ombo and Edfu on both banks of the Nile where it reaches its narrowest point. The site is generally known for its many Pharaonic cenotaphs, stelae and the speos of Horemheb, but it was once also the world’s largest quarry. As such it was renowned for its high quality sandstone, and the stone was extracted and transported to all overUpper Gebel el Silsila (Mountain of Chain) is located between Kom Ombo and Edfu on both banks of the Nile where it reaches its narrowest point.

Measurements of e+e- pairs from open heavy flavor in p+p and d+A collisions at s NN =200 GeV

We report a measurement of e+e- pairs from semileptonic heavy-flavor decays in p+p collisions at sNN=200 GeV. The e+e- pair yield from bb and cc is separated by exploiting a double differential fit done simultaneously in dielectron invariant mass and pT. We used three different event generators, pythia, mc@nlo, and powheg, to simulate the e+e- spectra from cc and bb production. The data can be wel

Five “New” deities in the Roman Pantheon at Gebel el-Silsila

The list of Egyptian deities attested in Greek and demotic inscriptions in the sandstone quarries of Gebel el-Silsila comprises Amun, Horus, Hathor, Isis, Khnum, Montu, Pachimesen, and Shaï. Several new inscriptions and divine names are here added to previous records: the Egyptian gods Min, Bes, Tutu, and the Greek goddesses Athena and TycheThe list of Egyptian deities attested in Greek and demotic inscriptions in the sandstone quarries of Gebel el-Silsila comprises Amun, Horus, Hathor, Isis, Khnum, Montu, Pachimesen, and Shaï.

In the footsteps of Ricardo Caminos : Rediscovering the Gebel el Silsila and its rock-cut temple

Though long admired for its Pharaonic stelae, shrines, and rock-cut temple, the grand ancient site of Gebel el Silsila remains fairly unknown withinmainstream archaeology. A general idea is that the site operated merely as a sandstone quarry, but few are aware of its rich archaeology thatincorporates evidence of millennia of human activity and cultural features that meet seven of UNESCO’s ten outs

Private Scarabs from Gebel el-Silsila found during Excavations in the New Kingdom Necropolis

The current paper is aimed as a primary publication of eight scarabs assembled by the Swedish-Egyptian excavation team between 2015 and 2016, found in private tombs of the Eighteenth Dynasty necropolis at Gebel el-Silsila East. Each entry includes information about field number, dimensions, material, description, inscription, and dating if possible. Typology conclusions are based on comparisons to

Pre-settlement coral-reef fish larvae respond to magnetic field changes during the day

Observations of coral-reef fish larvae have revealed remarkably consistent orientation behaviour while swimming offshore, requiring large-scale orientation cues. However, the mechanisms underlying this behaviour are still being investigated. One potential large-scale cue for orientation is the Earth's geomagnetic field. Here, we examined the effect of magnetic field manipulations on the orientatio

The biology of color

Coloration mediates the relationship between an organism and its environment in important ways, including social signaling, antipredator defenses, parasitic exploitation, thermoregulation, and protection from ultraviolet light, microbes, and abrasion. Methodological breakthroughs are accelerating knowledge of the processes underlying both the production of animal coloration and its perception, exp

Performance and manufacturability tradeoffs of different electrical machine designs

This work addresses the manufacturability challenges in traction machine production systems and design. The tradeoffs between performance and manufacturability of a heavy duty traction machine for buses and trucks, are investigated for four different winding designs, with multiple stator combinations, all using the same interior permanent magnet rotor. We present an analysis of electromagnetic, th

Managing soil natural capital : a prudent strategy for adapting to future risks

Farmers are exposed to substantial weather and market related risks. Rational farmers seek to avoid large losses. Future climate change and energy price fluctuations therefore make adaptating to increased risks particularly important for them. Managing soil natural capital—the capacity of the soil to generate ecosystem services of benefit to farmers—has been proven to generate the double dividend:

Structural and optical properties of Cu2ZnSn(S,Se)4 films obtained by magnetron sputtering of a Cu2ZnSn alloy target

Results of the study of structural and optical properties of Cu2ZnSn(S,Se)4 thin films obtained by sulfitation (selenization) of Cu2ZnSn films which were sputtered by target direct current magnetron sputtering using a stoichiometric Cu2ZnSn (99.99%) target are presented. It has been found that Cu2ZnSn(S,Se)4 thin films are polycrystalline with a grain size of ~60 nm. The optical bandgap of Cu2ZnSn

Autonomic deployment decision making for big data analytics applications in the cloud

When changes happen to big data analytics (BDA) applications in the Cloud at runtime, the affected BDA applications have to be re-deployed to accommodate the changes. Deciding the most suitable deployment is critical and complicated. Although there have been various research studies working on BDA application management, autonomic deployment decision making is still an open research issue. This pa
