Cari koleksi dengan cepat sesuai kebutuhan Anda.The Rogaland Igneous Complex (RIC) in southern Norway intruded into post-Sveconorwegian granulite facies crust ∼930 Ma. It includes three massif anorthosites, several small leuconorite bodies and the ∼7 km thick norite-quartz mangerite layered Bjerkreim-Sokndal (BKS) intrusion. The intrusion consists of five rhythmic megaunits created by repeated magma influxes topped by a transitio…
We describe a novel multi-GeV photon detector which operates under an intense flux of neutrons. It is composed of lead–aerogel sandwich counter modules. Its salient features are high photon detection efficiency and blindness to neutrons. Monte Carlo (MC) simulations show that the efficiency for photons with energy larger than 1GeV is expected to be higher than 99.5% and that for 2 GeV/c neutr…
Although the majority of teleost fishes possess a fused lower jaw (or mandible), some lineages have acquired a secondary joint in the lower jaw, termed the intramandibular joint (IMJ). The IMJ is a new module that formed within the already exceptionally complex teleost head, and disarticulation of two bony elements of the mandible potentially creates a ‘‘double-jointed’’ jaw. The appare…
Research quality is an increasingly important metric for determining funding allocations, promotion and tenure, and professional prestige. A key metric often used as a proxy for research quality is the ranking of the journal in which a manuscript appears. While citation-based measures of journal quality are commonly used, less is known about other dimensions of journal quality and prestige. We …
