A phenomenological treatment of thermal expansion in crystals of the lower symmetry classes and the crystal structures of CaCoSi₂O₆ and CaNiSi₂O₆
… indialite (hexagonal cordierite), emerald and beryl and for the clinopyroxenes: diopside, hedenbergite, jadeite, ureyite, acmite, and spodumene. The extended Grüneisen equation has been used to further examine the nature of the thermal expansion in emerald, beryl, and diopside. The crystal …

Beryllium analysis
… as was shown by the absence of characteristic beryllium lines in the ultraviolet spectrum of these minerals, The sample of Beryl probably containers 10% or less BeO, instead of the 14% as indicated by the Parsons and Barnes method of analysis. Al(OH)₃ is appreciably soluble in the boiling …

Geology & Geochemistry of the Kingman Feldspar, Rare Metals and Wagon Bow Pegmatites
… in the Rare Metals pegmatite, have muscovite and beryl. With the exception of the Kingman pegmatite, they exhibit normal LREE-HREE distributions. The Kingman pegmatite is extremely LREE enriched, HREE depleted and exhibits an unusual Nd enrichment which, in some cases, is sufficiently high that …

Mineralogy and Geochemistry of the Dumper Dew Pegmatite, Oxford County, Maine
… such as K-feldspar, muscovite, garnet, apatite, beryl, spodumene, triphylite-lithiophilite, tourmaline, cassiterite, and columbite-tantalite were attained via instrumentation assay. These trends illustrate an enhanced degree of magmatic differentiation relative to other pegmatites in the area.

The Mineralogy, Geochemistry and Phosphate Paragenesis of the Palermo #2 Pegmatite, North Groton, New Hampshire
An investigation of the beryl-phosphate subtype Palermo #2 pegmatite, located in the Grafton pegmatite field of New Hampshire, has revealed a large number of phosphate species. Late-stage, carbonate-bearing aqueous fluids have metasomatically altered primary phosphates producing a suite of nearly …

Lack of Affirmative Consent: Trauma in Jhumpa Lahiri’s “Interpreter of Maladies”
… “guilt” (Lahiri 63). The work of Tzuhsiu Beryl Chiu, however, stands out among the scholarship as it suggests that Bobby’s conception was the result of a rape rather than infidelity and that Mina has thereby “experienced great trauma and suffered the unspeakable pain alone” (172). If …

Petrogenesis of the Spruce Pine pegmatites, North Carolina
… of a common magmatic source. K-feldspar, garnet, beryl and tourmaline also have similar regional trends. Although the chemical core of the area revealed by the mineral chemistry does not correspond to an exposure of granodiorite, it may correspond to the core of a larger plutonic body that has not …

Using shared displays to support group design; A study of the use of informal user interface designs when learning to program
Hand-drawn sketches have traditionally been used to depict design ideas because they are quick to draw and can include as much or little detail as is required to convey the essence of the ideas. Computer tools are now an alternative and offer advantages for editing, storing and transmitting …

A study of bilingual children reading in a second language.
This research tested the hypothesis that bilingual children, using their second language and matched with monolingual children on a word recognition test, may differ significantly from them in the miscues made when reading and in attitudes to reading. Some prior research has indicated ethnic …
