The crop estimation analysis procedures documentation of the AgRISTARS - Foreign Commodity Production Forecasting Project (FCPF) is presented. Specifically it includes the technical/management documentation of the remote sensing data analysis procedures prepared in accordance with the guidelines provided in the FCPF communication/documentation standards manual. Standard documentation sets are given arranged by procedural type and level then by crop types or other technically differentiating categories

What Matters Most? A Survey of Accomplished Middle-Level Educators\u27 Beliefs and Values about Literacy

Ninety teachers working in award-winning middle schools responded to a survey that explored, quantitatively and qualitatively, how they (1) defined themselves as teachers of literacy, (2) viewed multiliteracies in adolescents\u27 lives, and (3) valued these literacies in the classroom. Mean scores indicated that Basic Literacies (e.g., comprehension, word identification, fluency, writing) were rated more favorably than New Literacies (e.g., media, Internet, critical, out of school). Strong qualitative support existed for literacy instruction in all disciplines, but interpretations varied. The most positive agreement centered on every teacher being a teacher of literacy. Little support existed for developing students\u27 out-of-school literacies in schools. Such findings have strong implications for altering curricular emphases and merging teacher practice with adolescents\u27 needs and interests

Development and test of advanced composite components. Center Directors discretionary fund program

This report describes the design, analysis, fabrication, and test of a complex bathtub fitting. Graphite fibers in an epoxy matrix were utilized in manufacturing of 11 components representing four different design and layup concepts. Design allowables were developed for use in the final stress analysis. Strain gage measurements were taken throughout the static load test and correlation of test and analysis data were performed, yielding good understanding of the material behavior and instrumentation requirements for future applications

An Activity-Based Nanosensor for Traumatic Brain Injury.

Currently, traumatic brain injury (TBI) is detected by medical imaging; however, medical imaging requires expensive capital equipment, is time- and resource-intensive, and is poor at predicting patient prognosis. To date, direct measurement of elevated protease activity has yet to be utilized to detect TBI. In this work, we engineered an activity-based nanosensor for TBI (TBI-ABN) that responds to increased protease activity initiated after brain injury. We establish that a calcium-sensitive protease, calpain-1, is active in the injured brain hours within injury. We then optimize the molecular weight of a nanoscale polymeric carrier to infiltrate into the injured brain tissue with minimal renal filtration. A calpain-1 substrate that generates a fluorescent signal upon cleavage was attached to this nanoscale polymeric carrier to generate an engineered TBI-ABN. When applied intravenously to a mouse model of TBI, our engineered sensor is observed to locally activate in the injured brain tissue. This TBI-ABN is the first demonstration of a sensor that responds to protease activity to detect TBI

Project communications/documentation standards manual

The standards apply to the identification and description of remote sensing technical crop estimation analysis procedures. Standard working terminology for technical project and programmatic communications among and between FCPF project technologists and managers as well as with other AgRISTARS projects and program management is established. Basic reference material for FCPF project technologists is provided. The material presented can be used as introductory training material for new technical personnel

Evaluation of Calcium Hydroxide-Treated Stover (Second Crop) in Receiving and Growing Diets and Effects on Cattle Performance

Production of ethanol from corn as an alternative fuel source has significantly affected the pricing landscape for corn as an energy source for livestock. As ethanol usage has become more prevalent, corn prices have become more volatile, especially in critical corn-growing areas that have been affected by drought. Consequently, many beef cattle feeders have become interested in alternative energy sources in an effort to control cost of gain. Second Crop (ADM Corp., Decatur, IL) is a process in which calcium hydroxide is added to fibrous crop residues, such as wheat straw and corn stover. When applied to low-quality roughages, calcium hydroxide disrupts the chemical bonds between lignin and hemicellulose, thus improving digestibility of the fiber by ruminal microbes. Treatment of low-quality forage with the Second Crop process could improve the energy value of forages, effectively decreasing reliance on cereal grains as sources of supplemental energy
