Flow behavior in liquid molding

The liquid molding (LM) process for manufacturing polymer composites with structural properties has the potential to significantly lower fabrication costs and increase production rates. LM includes both resin transfer molding and structural reaction injection molding. To achieve this potential, however, the underlying science base must be improved to facilitate effective process optimization and implementation of on-line process control. The National Institute of Standards and Technology (NIST) has a major program in LM that includes materials characterization, process simulation models, on-line process monitoring and control, and the fabrication of test specimens. The results of this program are applied to real parts through cooperative projects with industry. The key feature in the effort is a comprehensive and integrated approach to the processing science aspects of LM. This paper briefly outlines the NIST program and uses several examples to illustrate the work

Sea Power and Strategies For the Control of the Seas

Today, the United States is the dominant sea power of the world—unchallenged by friend, unchecked by foe. This position is as novel to the history of the republic as the advent of the atom bomb

Introduction to Command Intelligence

Today, I shall attempt to introduce the subject of Intelli­gence from an unconventional point of view—that of the com­mander rather than that of the intelligence officer—for intelligence is a function of command

A new model of procedural justice: Legal legitimacy, legal cynicism, and satisfaction with government officials

The alternative model of legal socialization proposes that legal legitimacy and legal cynicism mediate the relation between procedural justice and rule-violating behavior (Triter, 2012). In contrast, the direct model of procedural justice proposes that procedural justice predicts satisfaction with government (Tyler, 1988). The current study tested these models using secondary analysis of data collected in Eastern and Western Europe during the 1990s. The present study tested two competing hypotheses: legitimacy and cynicism would mediate the relation between procedural justice and satisfaction with government officials (alternative model) and procedural justice would predict satisfaction (direct model). Results indicated that procedural justice predicted satisfaction in Western Europe, which supported the direct model. Support was found for the alternative model in Eastern Europe. However, legal cynicism positively predicted satisfaction in Eastern Europe, contrary to previous research. This finding demonstrates the need to consider cultural context in studies of procedural justice

Meeting the Need: A Summary and Evaluation of Ny Farmnet

A.E. Res. 91-3New York FarmNet, a state supported, toll-free, phone help-line for farmers began in March 1986 in response to the farm financial crisis. Its purpose included providing information/refelTal, individualized business/financial analysis and a general safety net for farm families, From March 1986 through March 1991 FmmNet received 3853 calls and assigned 534 consultants to work one-to-onc with fm'm families experiencing severe problems. A summm'y of caller characteristics revealed that slightly over half of callers were males, and nearly all were owners or operators rather than farm workers. Each year caller fmm size averaged between 230 and 320 acres, but the range was from one acre to over 4000 acres. Years of fm'ming experience each year averaged 16 to 23 years, but the range was from I yem' or less to a lifetime. Average debt of callers each yem' averaged between $100,000 and$200,000, and several callers reported debt of over $1,000,000. The main reasons for calling FarmNet were financial or financial/legal problems, but many other reasons were given including need for job information and emotional stress, A 1990-91 phone survey sampled people who had called FarmNet in 1986-87. The survey asked about their recollections of help received from FarmNet. They were generally positive on the helpfulness of the phone operators and remembered considering a number of options as a result of a FarmNet consultant visit. About one third of those callers is no longer fm'ming, and one fifth is in a different type of farming than in 1986-87. Based on five years of the program, several conclusions were offered. 1) A segment of the fm'm population is likely to be at risk each yem'; hence, there is a continuing need for addressing such problems; 2) FarmNet served an audience that would not have been reached by previously existing programs; 3) FarmNet's accomplishments went beyond just focusing on problems of callers to build expertise within Cornell Cooperative Extension staff and networking with other agencies and help sources; 4) The program achieved a positive image under the difficult circumstances of sometimes being the messenger of bad news; and 5) individualized, demand-driven programs such as FarmNet require difficult policy choices in these times of tight budgets

Emergence of foams from the breakdown of the phase field crystal model

The phase field crystal (PFC) model captures the elastic and topological properties of crystals with a single scalar field at small undercooling. At large undercooling, new foam-like behavior emerges. We characterize this foam phase of the PFC equation and propose a modified PFC equation that may be used for the simulation of foam dynamics. This minimal model reproduces von Neumann's rule for two-dimensional dry foams, and Lifshitz-Slyozov coarsening for wet foams. We also measure the coordination number distribution and find that its second moment is larger than previously-reported experimental and theoretical studies of soap froths, a finding that we attribute to the wetness of the foam increasing with time.Comment: 4 pages, 4 figure
