MOSAIC: A Scalable reconfigurable 2D array system for NDT

This paper documents the development of a scalable 2D array system, or Mosaic that can be targeted at a wide range of NDT applications by way of a reconfigurable tile that can be tessellated to form arrays of any size and shape. Close coupling permits utilization of excitation voltages as low as +/-3.3V with insertion loss of 48dB on reflection from an aluminum back wall at 73mm achieved using 2D arrays without decoding

Does Adding an Extra Educational Intervention Add Value? The DairyBeef Train-the-Trainers Program

Extension educators seek to facilitate change among their clientele through educational programs. However, some programs are more effective than others. In this study, a half-day trainers program in dairy quality assurance moved individuals from one stage of learning to another (evaluation to learning or to gaining experience). However, the addition of a single follow-up reminder and additional materials to help trainers teach more effectively did not result in greater use of the program materials to instruct dairy producers. Somewhere between a single reminder and multiple interventions lies a useful compromise to ensure adoption of training messages and taking action

Planetary astronomy

The authors profile the field of astronomy, identify some of the key scientific questions that can be addressed during the decade of the 1990's, and recommend several facilities that are critically important for answering these questions. Scientific opportunities for the 1990' are discussed. Areas discussed include protoplanetary disks, an inventory of the solar system, primitive material in the solar system, the dynamics of planetary atmospheres, planetary rings and ring dynamics, the composition and structure of the atmospheres of giant planets, the volcanoes of IO, and the mineralogy of the Martian surface. Critical technology developments, proposed projects and facilities, and recommendations for research and facilities are discussed

Developing Herd Health Education for and Assessing Risky Practices of Cow-Calf Producers

Bovine respiratory disease (BRD) is an often unrecognized problem in cow-calf herds. We describe a program we used to help producers identify and avoid practices that could increase their herds\u27 risk for BRD. The greatest knowledge gains occurred for the topics of costs associated with BRD, BRD risks at the feedlot, and biosecurity measures. Through producer self-assessments, we found that the number of risky practices conducted by producers ranged from none to 22 per operation, averaging 10 per operation. Extension professionals should consider combining producer self-assessment with education on management as an effective strategy for informing producers of risks in their operations

Wet scavenging of soluble gases in DC3 deep convective storms using WRF-Chem simulations and aircraft observations

We examine wet scavenging of soluble trace gases in storms observed during the Deep Convective Clouds and Chemistry (DC3) field campaign. We conduct high-resolution simulations with the Weather Research and Forecasting model with Chemistry (WRF-Chem) of a severe storm in Oklahoma. The model represents well the storm location, size, and structure as compared with Next Generation Weather Radar reflectivity, and simulated CO transport is consistent with aircraft observations. Scavenging efficiencies (SEs) between inflow and outflow of soluble species are calculated from aircraft measurements and model simulations. Using a simple wet scavenging scheme, we simulate the SE of each soluble species within the error bars of the observations. The simulated SEs of all species except nitric acid (HNO_3) are highly sensitive to the values specified for the fractions retained in ice when cloud water freezes. To reproduce the observations, we must assume zero ice retention for formaldehyde (CH_2O) and hydrogen peroxide (H_2O_2) and complete retention for methyl hydrogen peroxide (CH_3OOH) and sulfur dioxide (SO_2), likely to compensate for the lack of aqueous chemistry in the model. We then compare scavenging efficiencies among storms that formed in Alabama and northeast Colorado and the Oklahoma storm. Significant differences in SEs are seen among storms and species. More scavenging of HNO_3 and less removal of CH_3OOH are seen in storms with higher maximum flash rates, an indication of more graupel mass. Graupel is associated with mixed-phase scavenging and lightning production of nitrogen oxides (NO_x), processes that may explain the observed differences in HNO_3 and CH_3OOH scavenging
