The Dakalasu No.1 pegmatitic rare-element deposit is a representative of Be-Nb-Ta pegmatites in Altai, Xinjiang, China. Beryl the most important beryllium-carrying mineral pegmatite. To constrain concentration mechanism Be, we conducted study textural relationships and chemical compositions (major trace elements) beryl, along with microthermometry Raman spectroscopy on beryl-hosted fluid inclus...

Beryllium is an extremely lightweight metal that occurs naturally in rocks, coal, soil, and volcanic dust. Commercially, bertrandite and beryl ore are mined for the recovery of beryllium. Because beryllium is one of the lightest metal and is very rigid, it has many uses in the electronics, aerospace, and defense industries. Beryllium is released into the atmosphere by windblown dust, volcanic p...

Tribute to Beryl T. (Sue) Atkins

This article addresses the social, cultural, and political history of backstreet abortion in post-war Britain, focusing on the murders of Beryl Evans and her daughter Geraldine, at Ten Rillington Place in 1949. It shows how the commonplace connection of John Christie to abortion and Beryl Evan's death was not a given in the wider public, legal, political, and forensic imagination of the time, r...

Content-intensive web sites, such as Google or Amazon, paginate their results to accommodate limited screen sizes. Thus, human users and automatic tools alike have to traverse the pagination links when they crawl the site, extract data, or automate common tasks, where these applications require access to the entire result set. Previous approaches, as well as existing crawlers and automation too...

The pegmatitic rocks located in the south-east of Côte d'Ivoire between Comoé basin and Sefwi belt are subject this study. geology region consists gneisses, granites, microgranites, amphibolites, mylonites metasediments. All these generally crosscut by quartz pegmatite lodes. petrographic studies allow us to discriminate four groups pegmatites on basis mineralogy: (i) beryl-muscovite bearing (A...

Despite its high toxicity, beryllium is widely used because of its unique properties. Beryllium is toxic both as a carcinogen and as the agent that initiates chronic beryllium disease (CBD). CBD, a granulomatous lung disease, is a cellmediated immune response to inhaled beryllium in 6–20% of exposed individuals. Considerable invesitagations into the nature and effects of CBD have been conducted...
