• Aerospace Industry Turns to Innovative Fastener Thread to Keep the Mission from Falling Apart
  reusability and ongoing resistance to ther-. mizing thread loosening, assembly, maintenance, and. mal expansion and contraction are necessary. The heart. service costs. The growing number of uses ranges. of the problem is the 60° "vee" thread design of tradi-. from aircraft cockpit instruments...
• Bolted Joint Uncertainties
  of these variables can be identified, but they rarely can be characterized for a production lot. Service loads: Through testing and experience, some industries can quantify the loads on their joints with a fair degree of certainty. However, while manufacturers can predict the loads their products should...

• Trellis-Tension Technology Fine-Tunes Grape-Yield Estimates
  is field-testing an automated system for estimating grape yields. The system is based on tension changes in trellis wire that supports the vines. The idea is to help growers and processors keep closer tabs on how crop yield is shaping up before harvest so they can adjust their pruning, watering...

• Beware Thermal Cycling in Bioprocessing Part 2
  sterilized, thermal cycling presents a further problem. When the test manifold was disassembled after thermal cycle testing, wear on the face of the gasket seal was observed. Wear and fretting of the gasket material was probably due to radial expansion and contraction of the gasket during heat-up...
