Berry, David E.; Carrie, Philippa; Fawkes, Kelli L.; Rebner, Bruce; Xing, Yao – Journal of Chemical Education, 2010
This experiment describes the reaction of palladium(II) chloride with 1,5-bis(diphenylphosphino)pentane by grinding the two powders together in the solid state. The product is the precursor for the metalation reaction at one of the methylene carbon atoms of the ligand's backbone. The final product is known to be a catalyst for Suzuki-Miyaura…

Corbani, S.; Chouery, E.; Fayyad, J.; Fawaz, A.; El Tourjuman, O.; Badens, C.; Lacoste, C.; Delague, V.; Megarbane, A. – Journal of Intellectual Disability Research, 2012
Background: Rett syndrome (RTT), an X-linked, dominant, neurodevelopment disorder represents 10% of female subjects with profound intellectual disability. Mutations in the "MECP2" gene are responsible for up to 95% of the classical RTT cases, and nearly 500 different mutations distributed throughout the gene have been reported. Methods:…

Champagne, Pascale; Li, Caijian – Bulletin of Science, Technology & Society, 2008
This study examines the hydrolysis of lignocellulose extracted from poultry manure for the purpose of investigating low-cost feedstocks for ethanol production while providing an alternative solid waste management strategy for agricultural livestock manures. Poultry manure underwent various pretreatments to enhance subsequent enzymatic hydrolysis…

Layland, Allison; Redding, Sam – Building State Capacity and Productivity Center, 2016
For decades, the regulations attached to federal education funds have shaped the forms and functions of state education agencies (SEAs), especially as state funding for these agencies has stagnated or diminished. In fact, the relationship between the SEA and the state's districts and schools has been colored by the strong tint of federal…

Lea, Tess; Thompson, Helen; McRae-Williams, Eva; Wegner, Aggie – Journal of Education Policy, 2011
"Engagement" is the second of six top priorities in Australia's most recent Indigenous education strategy to "close the gap" in schooling outcomes. Drawing on findings from a three-year ethnographic analysis of school engagement issues in the north of Australia, this article situates engagement within the history of Indigenous…

Smith, Andrea; Bondy, Elizabeth – Childhood Education, 2007
Student defiance, or resisting the authority of the teacher, is commonplace. In fact, some researchers have reported that the vast majority of discipline referrals are due to defiance. Due to the prevalence of childhood defiance and its potential for bringing instruction to a grinding halt, it is essential for educators to be prepared to…

Leung, Sam H.; Angel, Stephen A. – Journal of Chemical Education, 2004
Some Wittig reactions can be carried out by grinding the reactants in a mortar with a pestle for about 20 minutes, as per investigation. A laboratory experiment involving a solvent-free Wittig reaction that can be completed in a three-hour sophomore organic chemistry laboratory class period, are developed.

We reviewed studies involving the treatment of bruxism (i.e., teeth clenching or teeth grinding) in individuals with developmental disabilities. Systematic searches of electronic databases, journals, and reference lists identified 11 studies meeting the inclusion criteria. These studies were evaluated in terms of: (a) participants, (b) procedures…

Raffan, Deirdre – Primary Science Review, 2005
One activity that gets children thinking about how electricity is made involves exploring hydro (water) power. Water has been used as a source of energy for thousands of years for mechanical purposes such as grinding corn, bellows for furnaces or sawmills for cutting wood or slate. For about a century hydro power has been producing electricity…
