The Hazards of Oil Refineries and Other Industries

The Philadelphia Energy Solutions refinery will shut down as a result of its recent explosions and fires. Scott Jackson, PhD, a visiting professor of chemical engineering at Villanova University, says there are two parts to contamination—surface contamination and contamination of the water underground beneath the oil refinery. The surface contamination can be naturally bioremediated to some extent. At the worst, the surface can be removed and taken to a secure landfill or decontaminated by other means. However, organics like benzene, toluene and xylene (commonly known at BTX) that have reached deep into the underground water table beneath parts of the older parts of the plant can be difficult to remediate. An area of contaminated ground water must be pumped out using wells and treated on the surface using standard wastewater treatment technologies. Remediating this pool of contaminated underground water can take years depending on its area and concentration. Looking ahead, contaminated concrete will need to be removed to a secure landfill, and contaminated topsoil will also need to be removed. Equipment can be sold for scrap metal. Depending on the extent of the ground contamination, the company could either encapsulate it with asphalt or concrete or return the land to a more natural condition with plantings. Refineries aren’t the only operations at risk for hazardous incidents. “All manufacturing operations, including processing of food, the manufacturing of electronic chips, plastics, paints, gasoline, and virtually everything that we use in our daily lives use potentially dangerous operations where risks associated with accidents must be managed. Some of the most dangerous industries might surprise you: Large breweries have recurrent incidents where workers die due to suffocation, caused by carbon dioxide, and dust explosions from the processing of sugar have caused terrible damage and loss of life—a fact that few people understand.” The hazards of a refinery are more apparent than in other industries, so consequently many more people believe refineries are dangerous places, but Jackson notes that, due to decision and risk analysis, refineries should be and generally are no more dangerous than someone driving their car to work.

Otterbein’s engineering program focuses on adding diversity to the profession

In April, Otterbein granted degrees to its first class of engineering graduates. While it’s a historic moment for the school, the class is important for another reason: it exceeds the national graduation rate for women in engineering. Otterbein is working in an intentional way to recruit a diverse class of engineers in a field that is increasingly looking for well-trained professionals who bring diverse opinions and ideas to the table. According to the American Society of Engineering Education, the national average for females earning bachelor’s degrees in engineering is 19.9%. The average for minority students graduating with engineering degrees is just 7%. Amongst the 21 students graduating from Otterbein, 29% are female and 29% are minority students. The inaugural class was also the first class to study in The Point at Otterbein University, an experiential learning facility focused on collaboration with businesses, community makers and academics. At The Point, students have opportunities to pursue industry projects and on-campus internships with resident professionals from some of the country’s largest and most respected businesses, like JPMorgan Chase and Nestle, and locally based companies, like Worthington Industries, Nikola Labs and edgeThingZ. Of the 21 graduating students, several are pursuing graduate studies at The Ohio State University and Santa Clara University, while others have already accepted full-time jobs at companies like Honda and Williams-Sonoma. “The students in this class helped us develop a strong program and accomplished a lot during their four years,” said Mike Hudoba, assistant professor of engineering. “Looking back on what they started with, it’s such a neat legacy they get to leave behind. They’re all hardworking students who entered into this new program with us.” Are you covering or would you like to learn more about Otterbein University and its engineering program?

Fundamental research hailed as new horizon in hypersonic flight

PHOTO Cutline: Mohamed Gad-el-Hak, Ph.D., professor emeritus in Virginia Commonwealth University’s Department of Mechanical and Nuclear Engineering. (Photo courtesy of the VCU College of Engineering) Mohamed Gad-el-Hak, Ph.D., Professor Emeritus in VCU’s Department of Mechanical and Nuclear Engineering, together with investigators at the University of Peking, China, has revealed an aerodynamic heating mechanism that sheds new light on the behavior of ultra-high-speed aircraft.         Their discovery comes as news outlets including CBS, CNN and the Washington Post are reporting on the tightening race among China, the U.S. and Russia for dominance in hypersonic systems, aircraft and weapons that travel more than five times the speed of sound.         Researchers previously thought sudden heat spikes, which make hypersonic flight impractical for many applications, occur when air flows reach maximum turbulence. However, Gad-el-Hak and his collaborators have demonstrated through theory, experiments and numerical simulations that temperatures actually jump just before turbulence sets in. The National Science Review has called their achievement “a major progression in hypersonic transition.” The American Institute of Physics said this investigation denotes “a new horizon” for future studies of hypersonic heating phenomena.        The discovery is expected to accelerate applied military and commercial hypersonic research for the design of future spacecraft, intercontinental ballistic missiles and hypersonic vehicles. Gad-el-Hak emphasizes that such applications result from fundamental research. Unlike applied investigations, which set out to solve practical problems, fundamental research seeks to improve scientific understanding of the natural world.         “I have two unflinching scholarly beliefs,” Gad-el-Hak said. “Fundamental science eventually, albeit in fits and starts, leads to a nation’s health, happiness and prosperity, and ‘walls’ between nations hinder that progress.”        

Baylor Researchers Awarded Grant to Develop Diabetes Mobile Health App for Use in India

An interdisciplinary team of Baylor University researchers – from nursing and business information systems to art and video game design – and physicians from Bangalore Baptist Hospital in Bengaluru, India, were awarded a 21st Century Knowledge Initiative Grant from the U.S. India Education Foundation (USIEF) to develop a diabetes mobile health app to boost awareness and educate those in India who are most at risk for diabetes. The team is led by Shelby Garner, Ph.D., R.N., assistant professor in Baylor’s Louise Herrington School of Nursing, who has worked in India over the past six years to develop technological health resources. She cited statistics from the World Health Organization that show life expectancy in India is among the lowest in the South East Asian Region and is largely attributed to growing rates of non-communicable diseases, such as diabetes. Contextualized health education is one key to help raise awareness in the country, she said. “There is a need for culturally appropriate health education materials in India,” Garner said. “Our early research showed that technology, such as smartphones and internet accessibility, are widely available in India among health providers, but most technological educational resources were developed in the West and do not effectively translate to the Indian context.” Physicians from Bangalore Baptist Hospital will provide cultural context and help identify important medical content to be included in the app. “Our diabetes app will feature an interactive 3D animated video with gaming features to help educate patients at risk for diabetes,” Garner said. “Answers to questions addressed in the app include: What is diabetes? What happens if I have diabetes? How do I prevent and treat diabetes? What do I do now?” The app also serves as a data collection tool to help researchers determine if the video is improving participants’ knowledge on diabetes. Community health workers employed by Bangalore Baptist Hospital will use the app as they visit with people in rural villages and urban slums during door-to-door health education visits, Garner said. The research team will compare the app’s effectiveness with standard health educational resources previously used. Garner said the USIEF grant was awarded, in large part, due to the success of an earlier project that led to the development of a hypertension app. “Earlier this year, we tested the hypertension app among 346 people in one of the largest slums in Bengaluru, India, and in several rural villages surrounding Bengaluru,” she said. “The app was significantly effective in improving knowledge among participants. We used these results to justify the need to design more resources and applied for funding from the U.S. India Education Foundation.” From previous experience developing and employing the hypertension app, Garner said she knew this new project would require input from a variety of perspectives. “I’ve realized some of the ‘big picture’ challenges in health education, and it will take a team of experts to make this happen,” she said. Team members are: • Shelby Garner, Ph.D., R.N., assistant professor in Baylor’s Louise Herrington School of Nursing • Dr. Carol Elizabeth George, community health physician, Bangalore Baptist Hospital • Dr. Gift Norman, community health physician, Bangalore Baptist Hospital • Dr. Kingsly Victor, internal medicine physician, Bangalore Baptist Hospital • Hope Koch, Ph.D., associate professor of business information systems, Baylor’s Hankamer School of Business • Phil Young, Ph.D., assistant clinical professor of business information systems, Baylor’s Hankamer School of Business • Julia Hitchcock, M.F.A., associate professor of art, Baylor’s College of Arts & Sciences • Matthew Fendt, Ph.D., lecturer in computer science, Baylor’s School of Engineering and Computer Science The grant also will fund exchange teams of researchers and faculty from India to come to the U.S. and for Baylor team members to go to India to collaborate on the research for the next two years. The first team from India is due in late October. “We are really excited about the work we will do together with our Indian partners over the next two years,” Garner said.

Microsoft Working to Close the STEM Gap

Even with a higher priority placed on science, technology, engineering, and math (STEM) throughout education in the US, only a fraction of girls are likely to pursue a STEM career. According to the National Center for Education Statistics, while more than 57 percent of college undergraduates are women, only 18 percent progress into STEM careers. With a clear gap, Microsoft set out to better understand what causes girls and women to lose interest in STEM subjects and careers, as well as what strategies have the greatest potential to reverse the trend. According to Microsoft, the goal of the study “was to inform our work in this area and to share learnings with schools, government leaders, nonprofits, employers and others. What we learned is that conditions and context can make a significant difference to girls, young women and their interest in STEM. And the solution doesn’t necessarily require a curricula overhaul.” Dr. Shalini Kesar, Associate Professor of Information Systems at Southern Utah University and advocate for women in technology, has known for years that girls and young women are a critical missing part of STEM studies and careers. “The stubborn gender disparity in STEM fields has sparked important debates on the underlying reasons,” said Kesar. “Some attribute the gender disparity to social and infrastructural factors, lack of mentors and role models, and lack of awareness about what these fields offer in terms of educational and career opportunities. Others point to studies that indicate traditional mindsets of computing as ‘boring’ and ‘only for boys’ as a major reason why girls and young women do not consider a degree or career in this field.” The study found that “we may be able to make significant strides just by showing girls and young women how STEM knowledge is applicable outside of the classroom, and how it can power their aspirations to make the world a better place.” “Recently, I was invited to collaborate with Microsoft on research which quantifies many of my observations from over 20 years of working to reduce the gender gap in STEM and computing,” said Kesar. “This work is an essential step forward in helping us learn more about how girls and young women currently perceive STEM.” Dr. Kesar was recently recognized by the Women Tech Council, receiving the Education Excellence Award at the 2016 Women Tech Awards.

The Value of a Cure and Do All Americans Benefit from Medical Breakthroughs?

On February 28, 2017 policymakers, health officials, industry representatives and patient advocates were meeting in Washington to discuss the ‘value of a cure’ – the costs, the public health benefits and how America will move forward following the passage of the 21st Century Cures legislation. The Act, which was signed in December promises to accelerate funding for biomedical research while it also loosens regulations governing drugs and medical equipment and devices. Innovations in medical research and technology have produced cures and breakthrough therapies to overcome diseases that were once considered a death sentence. Polio is preventable with a vaccine, HIV is managed with a daily drug regimen, and Hepatitis C now has a cure. But are these breakthroughs reaching all communities? How can we balance the high costs of drug development with affordability? And what can we do to ensure that new cures continue to be developed? This is where Virginia Commonwealth University can help. Our experts are thought leaders and are some of the go-to opinions in this field. Dr. Thomas Roper is a professor and the director of the Department of Chemical and Life Science Engineering at the VCU School of Engineering.
