Two years ago, I was warned by a friend that if I went with a Delta faucet, it would fall apart. I did not heed that advice because I liked Delta pull-out faucet model 474 NN (NN designates brushed nickel). Indeed, two years later, threads in the soft plastic that holds the aerator in the spout stripped. To its credit, Delta customer service shipped a new spout free of charge the day after I filled out a simple e-mail form describing the problem. In checking on the order , a cheery and competent customer service rep came on the line and confirmed the shipment. I was impressed.
But it made me wonder what type of plastic was used in the spout. What were engineering and cost tradeoffs made in deciding what plastic to use? I'm mechancial enough to screw in an aerator without mauling the threads, but I thought this plastic was unusually soft. After all, anyone is going to clean the aerator from time to time and that means removing it. So I my call is into Delta. Stay tuned for explanation or offer your if you have one.

The increased adoption of wireless technology for mission-critical applications has revved up the global market for dynamic electronic general purpose (GP) test equipment. As the link between cloud networks and devices -- smartphones, tablets, and notebooks -- results in more complex devices under test, the demand for radio frequency test equipment is starting to intensify.
Much of the research on lithium-ion batteries is focused on how to make the batteries charge more quickly and last longer than they currently do, work that would significantly improve the experience of mobile device users, as well EV and hybrid car drivers. Researchers in Singapore have come up with what seems like the best solution so far -- a battery that can recharge itself in mere minutes and has a potential lifespan of 20 years.
Some humanoid walking robots are also good at running, balancing, and coordinated movements in group settings. Several of our sports robots have won regional or worldwide acclaim in the RoboCup soccer World Cup, or FIRST Robotics competitions. Others include the world's first hockey-playing robot and a trash-talking Scrabble player.
