Engineers can derive professional benefits from Facebook, LinkedIn, Google+, Twitter, and other social media. Here is some practical advice on using these tools effectively, whether you are a veteran or a relative novice.
Nonlinearities in the response of a column to changes in operating conditions and in common economic valuation functions can have significant impacts on the economic optimum energy consumption for the column. Here’s a way to account for such...
I was taught that the word hopefully means “in a hopeful manner” or “full of hope.” Authors who start a sentence with the word hopefully usually mean “I (we) hope” or “it is hoped” — which is an incorrect usage of the word.
Between March and April 2010, a powerful but seemingly limited computer worm, now referred to as Stuxnet, infected computers around the world, beginning in Iran and spreading to Indonesia and India. A recently published book uncovers ﬁndings on the origin of the worm and raises concerns that are relevant to chemical engineers everywhere.
If you saw my last two editorials, you probably noticed the sustainability theme — “On the Path to Sustainability” in July, and “AIChE’s Path to Sustainability” in August. Through our work as chemical engineers, we have the potential to make significant positive impacts on sustainability. There’s also much we can do as individuals.
The ubiquity of digital and server-stored file formats has brought about increased interest in ensuring that creative works conceived today will be preserved, digitally, forever. Chemical engineers play an important role in preserving this in DNA...
I was really excited that this year’s Annual Meeting was being held in Pittsburgh. Having grown up in southwestern Pennsylvania and gone to school at Carnegie Mellon, I was eager to get back to my roots and share my hometown with my coworkers — the excitement of a home Steelers game, a ride up the incline to gaze down at the city from Mount Washington, and maybe a cruise on the three rivers on the Gateway Clipper. Unfortunately, Hurricane Sandy forced me to rethink some of my plans, especially those that involved being outdoors. Although we were physically out of the storm’s direct path, we did feel some of its effects. (The nearly constant, cold, windy rain was hard to ignore.) Outwardly, we did what we normally do to orchestrate an annual meeting — which was a great success (pp. 54–55) in spite of the weather.
Build safety into your process by substituting less-hazardous materials and chemistry, minimizing inventories and equipment sizes, moderating operating conditions, and simplifying unnecessarily complex operations.
