Testing of the Racine Street Highway Bridge: City of Milwaukee

The object of this test was to determine experimentally, the live load stresses in the main members of the Racine Street Bridge, and thus to ascertain whether or not the theoretical live and dead load stresses were greater or less than the theoretical dead load plus the actual live load stresses. If less, the bridge could not be considered safe for the traffic which it now carries. The dead load stresses in the various members were determined analytically, and to these were added the respective live load stresses obtained by this test, thus obtaining the total stress in the various members

Mathematically gifted and talented learners: Theory and practice

This is an Author's Accepted Manuscript of an article published in International Journal of Mathematical Education in Science and Technology, 40(2), 213-228, 2009, copyright Taylor & Francis, available online at: http://www.tandfonline.com/10.1080/00207390802566907.There is growing recognition of the special needs of mathematically gifted learners. This article reviews policy developments and current research and theory on giftedness in mathematics. It includes a discussion of the nature of mathematical ability as well as the factors that make up giftedness in mathematics. The article is set in the context of current developments in Mathematics Education and Gifted Education in the UK and their implications for Science and Technology. It argues that early identification and appropriate provision for younger mathematically promising pupils capitalizes on an intellectual resource which could provide future mathematicans as well as specialists in Science or Technology. Drawing on a Vygotskian framework, it is suggested that the mathematically gifted require appropriate cognitive challenges as well as attitudinally and motivationally enhancing experiences. In the second half of this article we report on an initiative in which we worked with teachers to identify mathematically gifted pupils and to provide effective enrichment support for them, in a number of London Local Authorities. A number of significant issues are raised relating to the identification of mathematical talent, enrichment provision for students and teachers’ professional development

Native meadows: eastern Oregon, east of Cascades [2000]

Native meadows produce a significant portion of the hay used for winter feed in eastern Oregon. Without fertilization, an average meadow will yield approximately 1 ton of hay per acre. With proper fertilization, yields often can be increased by 2 to 3 tons, and hay quality such as protein content is improved. Native meadows fall into three broad classifications: (1) Nevada bluegrass, (2) rush-sedge-grass, and (3) rush. Nevada bluegrass meadows respond to applications of nitrogen. Rush-sedge-grass meadows respond to a combination of nitrogen, phosphorus, and sulfur. Rush (wire grass) meadows usually are flooded for long periods and do not respond to fertilization. Fertilized meadows usually reach optimum hay stage earlier than unfertilized meadows. Quality and protein content of early cut hay is greater than later cut hay.Revised May 1985.
