Doing Pandemic R&D as if There’s No Mañana: Charting a course to zig and zag our way out of the pandemonium we’re in

Since the beginnings of Sandia National Laboratories, Sandians have made the unthinkable not only thinkable, but also plannable and doable. Over time, we’ve tempered ourselves, studying and devising ways to deter, defend against, and blunt threats of mass death, destruction, and disruption. Now we, and all within our social circles, are living one of the nightmares that only a small fraction of our fellow Sandians have pondered, tackled, and anticipated––a virus that bypasses militaries, zips through borders, hitches to domestic travelers and commuters, makes its hosts unknowing dangers to others, overwhelms hospitals and clinics, hobbles governments, and takes away the lives and livelihoods of compromised and marginalized people everywhere. Taken by surprise, Sandians have dispersed and re-congregated into three interconnected camps. Those who determinedly and defiantly carry on with the work they’ve been doing since before the pandemic hit. Those who are doggedly mustering and redirecting their abilities, experience, education, and energies to get us to the other side of this crisis (without ending up on the Other Side in the process). And those who are in fight-or-flight mode because this virus is pushing them to their personal limits, directly threatening them and/or the lives, jobs, and businesses that matter to them. From these three camps (which some of us migrate between on a daily, hourly, or even minute-by-minute basis), we make our individual and collective attempts to hold it together, do our work, and live another day. While there is much about this that is beyond our control, we are anything but helpless. Each of us has specialized powers and influence that can be brought to bear on the big and small parts of this gnarly problem. It all starts with a personal and collective understanding of the situation we’re in.

RCT Module: 2.01 Radiological Documentation Course 52130 [Slides]

10 CFR 835 establishes radiation protection standards, limits, and program requirements for protecting individuals from ionizing radiation resulting from the conduct of DOE activities. It is important to maintain the proper documentation to ensure that these standards and requirements are being met.

Uninterruptible Power Supply Systems, UTrain Course 58423 [Slides]

Identify the principles of operation of uninterruptible power supply (UPS) systems, focusing on double conversion and offline/standby/backup types. The traditional UPS is now referred to as a “double conversion” UPS. The AC input power is rectified into DC. The DC feeds an inverter which provides the AC output. The DC bus is also connected to batteries. It is called double conversion because the first conversion is from AC to DC and the second conversion is from DC to AC. The inverter creates the output waveform to match the bypass input. Because of this, the static bypass switch may be switched between inverter and bypass seamlessly.

Human Lung Cellular Response to HCoV-229E Infection, Post-Translational Modification Proteomics Time Course (ACS-TZ-DP6)

The purpose of this experiment was to evaluate the human lung cellular response to wild type human coronavirus strain 229E (HCoV-229E) infection. Sample data was obtained for mock-infected and HCoV-229E infected immortalized human lung epithelial cells (A549) (MOI 3) and immortalized human lung fibroblasts (MRC-5) (MOI 3). Whole cell lysates were collected at 8, 16, and 24 hours post infection and were processed for post translational modification (PTM) proteomics analysis to determine the HCoV-229E phosphoproteome, redox proteome, and acetylation proteome.
