New bubble-based technique for leak detection at CCS offshore sites

Tampa Bay Real Estate Bubble Burst? Unlikely

With property prices seemingly on the rise and rising quickly in Tampa, there is a lot of talk about a real estate bubble in the US and dire predictions that the so-called bubble could burst, leading to a lack of confidence on the part of investors and people seeking a second home. But while this talk of a bubble may be true in some parts of America, it isn't justified in Florida, particularly in the Tampa Bay and Clearwater areas.

Break Out of Your Managerial Bubble

Hal Gregersen, executive director of the MIT Leadership Center at Sloan School of Management, says too many CEOs and executives are in a bubble, one that shields them from the reality of what’s happening in the world and in their businesses. The higher you rise, the worse it gets. Gregersen discusses practical steps top managers can make to ask better questions, improve the flow of information, and more clearly see what matters. His article “Bursting the CEO Bubble” is in the March-April 2017 issue of Harvard Business Review.

Methods and systems for generating thermal bubbles for improved ultrasound imaging and therapy

A method and system uniquely capable of generating thermal bubbles for improved ultrasound imaging and therapy. Several embodiments of the method and system contemplates the use of unfocused, focused, or defocused acoustic energy at variable spatial and/or temporal energy settings, in the range of about 1 kHz-100 MHz, and at variable tissue depths. The unique ability to customize acoustic energy output and target a particular region of interest makes possible highly accurate and precise thermal bubble formation. In an embodiment, the energy is acoustic energy. In other embodiments, the energy is photon based energy (e.g., IPL, LED, laser, white light, etc.), or other energy forms, such radio frequency electric currents (including monopolar and bipolar radio-frequency current). In an embodiment, the energy is various combinations of acoustic energy, electromagnetic energy and other energy forms or energy absorbers such as cooling.

Slurry bubble column reactor

A slurry bubble column reactor with a gas distribution arrangement comprising an upper sparger, a lower sparger, and an open-ended tube. Gas from the lower sparger enters the tube and lowers the density of slurry in the tube. The difference in slurry density causes the slurry in the tube to rise, causing slurry outside the tube to move down, maintaining circulation and flushing catalyst from the vessel wall.

how to explain a long-distance social distancing "bubble"

Me and my partner have decided to form a shared social distancing "bubble" with another of our couple friends. I believe we are following safe protocols for this but wanted to get an honest outside opinion as to whether we could be managing this better/safer/etc.

Here is the situation: I am a musician, and my main music collaborator used to live about a half hour from me. Back in January, he and his girlfriend relocated about 90 minutes away, in a major city that has had a large amount of COVID-19 cases. Where I live hasn't been as bad, but we are all still being cautious.

Musician friend and I are collaborating on a music recording project to combat boredom because we are both unemployed and obviously live gigs are right out. We have been doing most of our planning remotely, via Zoom and phone calls, but every now and again we do have to meet in person as his recording studio is in his apartment and sometimes he and the girlfriend come up here to ease the stir-craziness. We believe we are being safe in our methodology but wanted to confirm.

When we embarked upon this project, we made a pact with each other and our partners that the only people we would allow into our homes is each other. The way this works is, when I have to drive to his place to record, I wash my hands, mask up, and drive down to see him. He lives in a neighborhood with ample street parking near his building. When I arrive, I mask up again, buzz into his apartment, take off my outerwear and shoes immediately and keep it on a hook outside their front door, take mask off and put in my purse leave purse in one spot on a table, hand wash and hand sanitize. He and girlfriend also hand wash and hand sanitize, and have been cleaning all doorknobs and buzzer buttons and handrails of the stairs with disinfectant wipes before I arrive. When we record, we disinfect all microphones, headphones, gear we touch including instruments with wipes before and after use. When I leave, I wipe down the table where my purse was, wash hands again, mask up, drive home. All clothing I wear is promptly laundered.

When he comes up to work with me his protocol is similar: wash hands, mask up, drive to my house, where I have been disinfecting doorknobs and other surfaces. When he arrives, he parks in our drive, his outerwear and shoes stays out on our patio, he washes hands again and hand sanitizes, we rehearse for a couple hours, then he washes hands again, masks up, drives home, masks up, goes into building, washes hands. All clothes he wore go immediately into the laundry. Any surface he touches in my house gets pre-and-post wiped down with disinfecting wipes. We don't record in my home there is no gear to disinfect other than his guitar.

His girlfriend works from home and keeps herself separate from us when we record in their home. My boyfriend lost his job due to COVID but busies himself with projects in his home office while we rehearse in our home. The four of us have mutually agreed that we are the only other folks we will allow in our homes and we follow this safety protocol to the T every time we travel to see each other.

So, question 1) are we being safe enough, or are we being dumb? None of us so far has gotten sick and we are comfortable with our routine. How could we improve our safety protocol? Neither of us stop at gas stations to and from each other; we gas up on our own time and hand sanitize after doing so.

Question 2) Musician friend and I are getting ready to record a video of us performing a duet in his apartment. Our mutual friends know we no longer live near each other, and my fear is that when they see evidence that we haven't been keeping six feet apart at all times in his apartment we will get scorned by our colleagues, or near the brunt of actual anger because they are not aware of our safety routine. How can we explain that we have been talking proactive steps to keep ourselves safe and have chosen to be a somewhat long distance social isolation bubble with each other when we release this video to avoid angry responses? Is it necessary? Musician buddy is ambivalent, but I am a worrier and don't want to inadvertently bring us bad publicity.

Please be gentle with me. We are doing our best and we so far have not gotten sick with this protocol. Our partners are also proactive in hand sanitizing and/or hand washing once one of us leaves the other place. Are we being stupid? Is there a way to explain this succinctly when we release our video to pre-empt any judgement?

Seriously please be gentle. My anxiety is on high alert just from reading the news each day and I really hope this community will refrain from a pile on because we are doing everything we can to keep ourselves and our partners safe.

Any advice would be much appreciated. Thank you.

Access: Bubble of One

When you spend a lot of time on your own, as I do, you tend to notice things more, perhaps earlier. 
I think it was maybe early February when I started to feel quite concerned about a new virus from the same family as common colds but worse than influenza. I watched a documentary in February on the “Spanish Flu” and I learnt that we don’t know for sure where it originated. The reason it was coined Spanish Flu is because Spain was neutral in WWI and so they weren’t trying to hide the truth of their experience with this…
