Clarkson University Defends Against COVID-19 Through Technology

Potsdam, NY, Oct. 27, 2020 (GLOBE NEWSWIRE) — When Clarkson University commenced its fall semester planning back in the spring, it looked to be a daunting task to safely bring more than 3,000 students back to its main campus in Potsdam for both in-person and online classes — especially for a university known for its personal, rigorous hands-on learning.

Questions like “Can classrooms be safely used?” and “Do we have enough classroom technology for online and hybrid classes?” were on the minds of faculty and administrators.

Engineers from Clarkson’s CAARES (Center for Air and Aquatic Resources, Engineering Science) and experts from the University’s Office of Information Technology quickly went to work to make fall semester classes a reality, while still maintaining rigor in both learning and safety.

Suresh Dhaniyala, the Bayard D. Clarkson Distinguished Professor and co-director of CARES, took the lead on analyzing the performance of classroom ventilation systems.

“For the COVID-19 pandemic scenario, our focus was on knowing that any particles in the air could be evacuated quickly, so as to prevent cross-contamination between occupants,” says Dhaniyala.

An air exchange rate is the rate at which airflow is brought into a room and directly relates to the rate at which particles are removed from a room. A rate of 1 per hour implies that after one hour, the amount of fresh air brought in is equal to the volume of the room.

Most homes have air exchange rates of approximately 0.3 per hour.  At the other end of the spectrum, hospital operating rooms are required to have air exchange rates of 15 to 25 per hour.

“We evaluated our classroom air exchange rates using an aerosol injection system with particles of 500 nanometers to 5 microns, the same size as particles that escape from face masks and are responsible for airborne disease transmission,” says Dhaniyala. “We injected particles into each classroom and used sensors around the room to study the decay times.”

 Dhaniyala determined that many classrooms already had excellent air exchange rates of 6 to 10 per hour, significantly exceeding requirements. With an air exchange rate of 10 per hour, a particle injected during a class has a less than five percent chance of still being in that classroom after 20 minutes.

“We shared a few problem areas with University Engineer Michael Tremper, who was able to quickly adjust the ventilation systems in those spaces by using innovative engineering solutions,” says Dhaniyala.

At the same time, the classroom ventilation was being evaluated, teams from Clarkson’s Office of Information Technology were working to implement new technology into existing classrooms and to create new classrooms in non-traditional spaces like dining halls and larger multipurpose areas that could accommodate social distancing requirements.

“Our teams touched a total of 88 classrooms to ensure that every space is now equipped with a pen-touch display, webcam, microphone, and full lecture capture capabilities,” says Chief Information Officer Joshua Fiske. “Additionally, for faculty who are teaching online, we created a loaner pool of

Jared Kushner implies Black people don’t want to be successful as he defends Trump

Kushner’s comments, in an interview on Fox, seemed to say that Black people didn’t want to work for success and that people who mourned George Floyd were ‘virtue signaling’

Trump’s son-in-law Jared Kushner is receiving some backlash after an appearance on Fox News where he made a statement about the Black community.

During an interview with Fox & Friends on Monday the senior advisor to Trump implied Black people choose not to be successful.

“The thing we’ve seen in the Black community, which is mostly Democratic,” said Kushner, “is that President Trump’s policies are the policies that can help people break out of the problems that they’re complaining about, but he can’t want them to be successful more than they want to be successful.”

After Kusher’s comments aired, Twitter responded furiously, making Kushner a trending topic almost immediately.

One user said: “In fairness, Jared Kushner’s definition of success is using his dad’s name to buy an old office building nobody wants to lease space in and then using the power of his access to the Presidency to get a bailout from corrupt emirs in the Persian Gulf.”

The online criticism included a rebuke from George Floyd family attorney Benjamin Crump who called his comments ‘blatant disrespect.’

Kushner also said that those who mourned and/or posted about Floyd’s death were ‘virtue signaling’ and doing more to polarize the country.

After the clip aired, White House Press Secretary Kayleigh McEnany released a statement obtained by NBC, where she says internet trolls blew the statement out of proportion.
