This paper builds on prior theory and research on attention and identity to examine whether and how industries publicly attend to external events. Events are critical triggers of institutional transformation and industry evolution. However, they must first become the focus of public attention to have this effect. We draw on a paired case comparison of media coverage of eight nonroutine events a...

The chemical diffusion of fluorine in jadeite melt has been investigated from 10 to 15 kbars and 1200 to 14OO“C using diffusion couples of jadeite melt and fluorine-bearing jadeite melt (6.3 wt.% F). The diffusion profile data indicate that the diffusion process is concentration-independent, binarv. F-O interdiffision. The F-O interdiffusion coefficient ranges from 1.3 X IO-’ to 7.1 X lo-’ cm*/...

We present the Kr-Kr derived exposure ages for H-chondrites which were recently investigated for their Cl-Ar ages. After demonstrating that our Kr-Kr ages are reliable and reproducible we find hints that Kr/Kr and Kr/Kr might depend on the relative concentrations on the target elements Rb, Sr, Y, Zr, and Nb. In addition, the Kr-Kr ages for the large L-chondrite Gold Basin indicate that the Kr-K...

Introduction: Although chondrites are among the most primitive materials accessible to us, their chemical compositions are highly variable among groups of chondrites, reflecting several fractionation processes including condensation and accretion processes in the early solar system. Considering that CI chondrites represent a solar system standard in the elemental abundance [1] and that calcium ...

1- Introduction The sediment cores BAG, AZD and AM in the Babolsar, Jouybar and Zaghmarz areas are located at the southern Iranian part of the coastal plain of the Caspian Sea. These areas are contained by major mountain ridge, the Alborz in the south (Central Alborz Structural Zone). The Alborz Mountain represent the main source of terrigenous materials in the South basin of the Caspian Sea. ...

introduction the ahangaran pb-ag deposit is located in the hamedan province, west iran, 25 km southeast of the city of malayer . . the deposit lies in the strongly folded sanandaj-sirjan tectonic zone, in which the ore bodies occur as thin lenses and layers. the host rocks of the deposit are early cretaceous carbonates and sandstones that are unconformably underlain by jurassic rocks. ore miner...

A mineralogical study was undertaken of air heater deposits in a 300 MWe pf boiler located in Western Australia to understand the deposit formation in air heater sections of boiler as an aid to implement possible remediation actions. Several air heater deposit samples were collected in the selected regions of the air heater along with samples of the feed coal, bottom ash and fly ash for compari...

Although cool-season grasses increase DM yield at high N rates, N recovery (kg plant N kg 1 N applied) Nitrogen removal by cool-season grasses may aid in capturing exgenerally declines as N rate increases. Ramage et al. cess N from animal confinement operations or phytoremediation. (1958) reported fertilizer N recovery of 0.59 and 0.59 kg Limited information exists on the N dynamics of these gr...

The concentrations of some trace elements (such as Fe, Ag, Zn, Mn, Cu, Cd, Mg, Ca, Na, K) were determined in the fruiting bodies of Fly Agaric Amanita muscaria (L.: Fr.) Pers. The mushrooms were collected in Poland in 1999 and 2000. The samples of dried and pulverized mushrooms (separately the caps and the stalks) were wet digested with concentrated nitric acid in PTFE vessels under pressure in...
