YPOV
Meagan Lewis
Programming for an AIChE conference — i.e., developing the technical program — takes a lot more than the work put in by the meeting chairs; the details and ideas that go into every session and its roster of speakers take a whole force of volunteers. As a co-chair for the upcoming 2014 Spring Meeting in New Orleans who also happens to be a young professional (YP), I’ve realized that the best way to prepare for programming a large-scale conference is to build relationships across all levels of the organization.

CEP: YPOV - Engineering Your Job Change through Networking

January
2015
YPOV
Sarah Ewing
In the current job market, people rarely stay employed with the same company that hired them after college for their entire career. If you want to take control of your career and make a job change that is consistent with your professional and personal goals, allow enough time to weigh the pros and cons instead of making the decision on a whim. The most critical step in this process is not updating your resumé, but making sure that the new position will be a good fit and not just a quick fix. I like to think of changing jobs as a process with four key steps: recognizing that it is time to move on, deciding where you want to go, determining what you need to get there, and then networking your way in.

CEP: Spotlight on Safety - Be Prepared, Be Safe, and Have Fun

August
2014
Spotlight on Safety
Louisa Nara
One of my favorite warm weather activities is kayaking. The river provides a respite away from crowds and electronic distractions. Daily stressors are erased by the warm sun, a light breeze, and the sound of water lapping at my boat. A recent weekend with great weather afforded the perfect opportunity to go out on the river with my husband. Earlier that week, severe storms blew through the area with significant rainfall and flash flooding. This increased the volume of water in the river, so conditions would be perfect for a fast and exciting ride. It also called for a more-mindful approach to safety hazards, like swift currents and debris in the water.

CEP: YPOV - Capturing CO2 with a Green Focus

Pablo Duarte, Seth Gottlund
In a unique collaboration with the U.S. Dept. of Energy’s (DOE) Industrial Carbon Capture and Storage (ICCS) program, Air Products and Chemicals, Inc. (APCI) has developed an innovative process to capture CO2 at its Port Arthur, TX, facility. The captured CO2 is purified, dried, compressed, and transported via pipeline to Denbury Resources, where it is used in enhanced oil recovery (EOR). The high-purity CO2 is injected into oil wells to reduce the viscosity of the oil mixture, which enables higher oil-well production rates and overall yield, and increases the crude oil flowrate.

Cynthia Mascone
A recent Twitter post from Discover magazine, “20 Things You Didn’t Know About … Failure,” caught my attention and got me thinking about failures and mistakes. Curious, I did a bit of research. I found numerous lists of famous people who failed, some multiple times, and sometimes miserably, before they succeeded at what they are now famous for. Among them: the Beatles, Ludwig van Beethoven, Winston Churchill, Charles Darwin, Walt Disney, Thomas Edison, Albert Einstein, Henry Ford, Bill Gates, Michael Jordan, Abraham Lincoln, Isaac Newton, J. K. Rowling, Steven Spielberg, Oprah Winfrey, to name a few. They picked themselves up, dusted themselves off, and started all over again, learning from their mistakes.

Countless books and articles have been written about leadership — on such topics as the differences between managing and leading, what makes a good leader, and how to become a better leader, among others. One frequent topic: Are leaders born or made? The Center for Creative Leadership (CCL) posed this question to C-level executives of companies in 53 countries ( www.ccl.org/leadership/pdf/research/areleadersbornormade.pdf ). Slightly more than half (53.4%) of the top executives think leaders are made, about a fifth (19.1%) think they are born, and a little more than a quarter (28.5%) think leaders are both born and made.

Yes, I can access books and newspapers on my iPad. But actually reading them is another matter.

Cynthia Mascone
The word deadline has its roots in the American Civil War. Camp Sumter (also known as Andersonville Prison) was the largest and most infamous military prison of the war. The prison pen was surrounded by a 15-ft-high log fence with sentries stationed at 90-ft intervals. Inside the stockade, about 20 ft from the wall, was the “dead-line,” which prisoners were forbidden to cross. It was marked by a post-and-rail fence, and the guards had orders to shoot anyone who tried to cross it, or even reach over it.

The goal of bioprocessing is to optimize natural or artificial biological systems by manipulating prokaryotic and eukaryotic cells and their environment to produce biopharmaceutical products. A bioprocess is divided into upstream and downstream operations. Upstream processing encompasses the steps from preliminary unmodified cell line culture to the mature modified cell culture and harvest; downstream processing includes the separation and purification of the biologics from the mature activated cell culture. These operations have typically been performed as batch processes.
