Rural Competitiveness: Results of the 1996 Rural Manufacturing Survey

Establishments in metropolitan and nonmetropolitan locations are surprisingly similar in their adoption of new technologies, worker skill requirements, use of government programs and technical assistance, exports, and sources of financing, according to the results of a nationwide survey of 3,909 manufacturing businesses. The most widespread concern of both metro and nonmetro businesses appears to be with quality of labor. Survey respondents report rapidly increasing skill requirements, and many report problems finding qualified workers. Quality of local labor is the most frequently cited problem associated with nonmetro business locations. Access to credit, transportation, and telecommunications infrastructure is a problem of secondary importance for both metro and nonmetro respondents. Rural communities face a considerable challenge in supplying workers with needed skills. The fastest-growing skill requirements -- computer, interpersonal/teamwork, and problem-solving skills -- are not central to traditional academic instruction.rural manufacturing, sample survey, worker skills, manufacturing location, credit availability, technology adoption, Community/Rural/Urban Development,

Draft genome sequence of the naphthalene degrader Herbaspirillum sp. strain RV1423

Herbaspirillum sp. strain RV1423 was isolated from a site contaminated with alkanes and aromatic compounds and harbors the complete pathway for naphthalene degradation. The new features found in RV1423 increase considerably the versatility and the catabolic potential of a genus of bacteria previously considered mainly to be diazotrophic endophytes to plants

Americas Electoral Future The Coming Generational Transformation

A report building on a previous 2018 report issued by the authors as part of the States of Change project. The 2018 report examined various future presidential election scenarios (from 2020 through 2036) that could occur due to demographic changes at the state and national level over the next several decades. This revised 2020 report updates the scenarios with new demographic projections based on the latest census data, explicitly incorporates gender into the projections and scenarios for the first time, and examines the likely evolution of generational cohorts over the next several decades.

Methodology for the characterization of elastic constants of wood from tree branches

In biomechanical analyses, computational models are essential tools for simulating the behavior of a tree subjected to a load. However, such models allow only approximation of the actual behavior of the tree if the elastic parameters of the wood in different tree parts (stem, branches, and roots) and at least orthotropic behavior are not considered. In addition, as the wood is green, the parameters of strength and stiffness must be adequate for this level of moisture. However, even for stem wood, knowledge of elastic properties is not available for most species used in urban tree planting, and this scarcity of information is even greater for wood branches. The objective of this research was to evaluate methodology, based on wave propagation, in characterizing the 12 elastic constants of wood from branches. Complementarily, compression tests were performed to characterize the strength. The obtained elastic parameters using ultrasound tests were comparable with the values expected based on theoretical aspects related to the behavior of the wood. The results of the compression test complemented the ultrasound characterization, but the application of this method for the complete characterization of the elastic parameters is not feasible for tree branches because of their small size.1448439845

Les élastomères thermoplastiques sont des matériaux relativement nouveaux qui se caractérisent à la fois par une mise en oeuvre rapide analogue à celle des polymères thermoplastiques et par des propriétés intermédiaires entre celles des élastomères vulcanisés et des polymères thermoplastiques plastifiés. On passe en revue de façon succincte les principaux élastomères thermoplastiques commerciaux ou en développement. Pour chacun d'eux, on décrit brièvement la structure, les propriétés, la mise en oeuvre et les applications. Thermoplastic elastomers are relatively new materials that are characterized both by rapid implementation, similar to that of thermoplastic polymers, and by properties intermediate between those of vulcanized elastomers and plasticized thermoplastic polymers. This article makes a succinct review of the leading commercial thermoplastic elastomers or the ones being developed. For each of them, a brief description is given of the structure, properties, implementation and applications
