Fellow academics, when are we going to start fixing our urgent structural problems that strain family bonds and present ongoing barriers to diversifying our educational and scientific leadership? You wonder, what the heck is this guy talking about?

1/ Automobiles and Intake Fraction. Since cars are back in the news I thought I would retweet this model result I offered in early April 2020. I focused only on 1 micron particles & accounted for windows completely closed & cracked slightly open.
2/ Related air exchange rates were based on experimental results in literature for mid-sized sedans. Particle deposition to indoor surfaces were accounted for, as the surface to volume ratio in a 3 m3 cab is large. An important outcome was the intake fraction (IF)
3/ Here, IF is the number of particles (or virions in collective particles) inhaled by a receptor DIVIDED BY the number or particles (or virions in collective particles) emitted by an infector.
4/ Integrated over the two hour drive (in this example) the IF for all windows closed & a receptor at rest is 0.08 (8% of what comes out of the infectors respiratory system ends up in the respiratory system of the receptor). 8%! That is a very high intake factor.
5/ With additional ventilation from cracking a window open drops the IF to 0.012 (1.2%) still relatively high. Can get lower by opening more windows.
Simulation: Riding in car for 120 min w/ infected passenger who seems fine other than a cough every few mins. (1) a lot of SARS-CoV-2 virus (in fine aerosol particles) accumulation in car cabin w/ windows closed; (2) cracking window open slightly = dramatic reduction. #COVID19 pic.twitter.com/bCmrmnLUPG

Chandeshwara/Chandikeshwara is regarded as custodian of Shiva Temple's wealth&most of Shiva temples in South India has separate sannathi for him.
His bhakti for Bhagwan Shiva elevated him as one of foremost among Nayanmars.
He gave importance to Shiva Pooja&protection of cows.
There are series of paintings, illustrating the #story of Chandikeshwar in the premises of
Sri Sathiyagireeswarar #Temple at Seinganur,near Kumbakonam,TN
Chandikeshwara's birth name
is Vichara sarman.He was born in the village of Senganur on the banks of River Manni.
His Parent names were Yajnathatan and Pavithrai.
Vichara Sarman was a gifted child and he learnt Vedas and Agamas at a very young age.
He was very devout and would always think about Bhagwan Shiva.
One day he saw a cowherd man brutally assaulting a cow,Vichara Sarman could not tolerate this. He spoke to cowherd: ‘Do you not know that the cow is worshipful & divine? All gods & Devas reside in https://t.co/ElLcI5ppsK it is our duty to protect cows &we should not to harm them.
