Shahab Ahmed’s What Is Islam? The Importance of Being Islamic (2016) challenges anthropologists, Studies scholars, art historians and museum practitioners to question the theological assumptions underlying conceptions material culture. This article analyses three object types key analysis – figural painting, musical instruments wine bowls from vantage point collection Dutch National Museum Worl...

Two ceramic smoking-pipe bowls, excavated in Lalibela Cave, Begemeder Province, Ethiopia, were radiocarbon dated to 1320 ±2 80 A.D. A modified thin-layer chromatographic technique, applied to the pipe residues, yields positive tests for cannabis-derived compounds. Long-lived cannabinoids, produced by the heat of smoking from short-lived psychoactive ingredients in cannabis, makes identification...

To realize new and directed self-assembly (SA) pathways, the focus in colloid science and nanoscience has shifted from spherical particles and interactions to increasingly more complex shapes and interparticle potentials. This field is fueled by recent breakthroughs in particle synthesis, such as particles with complementary shapes that allow for specific lock-and-key interactions induced by de...

Many markets have “unraveled” and experienced inefficient, early, dispersed transactions, and subsequently developed institutions to delay transaction timing. However, it has previously proved difficult to measure and identify the resulting efficiency gains. Prior to 1992, college football teams were matched for post-season play up to several weeks before the end of the regular season. Since 19...

Nowadays, an accurate and precise description of the combustion phase is essential in spark-ignition (SI) engines to drastically reduce pollutant greenhouse gas (GHG) emissions increase thermal efficiency. To this end, computational fluid dynamics (CFD) can be used study different phenomena involved, such as ignition charge, development, formation. In work, a validation CFD methodology based on...

Abstract On the >1 µm scale morphology of semicrystalline plastics like polyethylene or Nylon features spherulites, “shish-kebabs”, cylinddrites and other crystalline aggregates which strongly affect mechanical material properties. Current imaging techniques give only a 2D picture these objects. Here we show how they can be visualized in 3D using fluorescent labels confocal microscopy. As re...

Artificial nests have been used to study factors affecting nest success because researchers can manipulate them more than natural bird nests. Many researchers have questioned the validity of generalizing the results from artificial nests onto naturally occurring nests. Other studies have assessed the validity of artificial nest studies by simultaneously comparing overall depredation or daily su...
