Dee Dee Dawdles in Downtown Dayton


ABC Wednesday is a word meme with participants from around the world. This fabulous meme was created and hosted by Mrs. Denise Nesbitt who hails from Great Britain. Over time, others have joined in to help host this wonderful and informative meme. We are now in our TENTH round! Some of the participants have been with this from the very first round; others have joined in along the way. Each week we are taken across the globe to see the varied and exciting contributions people have taken the time to discover and capture. We start with the letter, "A" and each week we post something in regards to the next letter of the alphabet. This week's letter is, "D".

DOPPLER EFFECT



The Doppler effect (or Doppler shift), named after Austrian physicist Christian Doppler who proposed it in 1842 in Prague, is the change in frequency of a wave for an observer moving relative to the source of the wave. It is commonly heard when a vehicle sounding a siren or horn approaches, passes, and recedes from an observer. The received frequency is higher (compared to the emitted frequency) during the approach, it is identical at the instant of passing by, and it is lower during the recession (from Wikipedia). See, and you thought it only had to do with the weather forecast! That, my friends, is the Doppler radar, but based on this very principle.

DOWNTOWN


 As in, downtown Albuquerque. Not downtown Dayton. I've never been to Dayton!

DOUBLE EXPOSURE


My Nikon D200 has a setting for multiple exposures. You can set it to two exposures (one image over another). Or three. Or, four. Or, more. However, in the case of two exposures, it would be called a double exposure. I love using this setting as the results are always unpredictable!


DECANNULATION

Decannulation. Such an ODD. word. Spent some time in a hospital yesterday visiting a friend, and this word was on a sign on the wall. I forgot what the entire sign was about-cautioning caretakers about turning a patient as decannulation can happen (and was something important to be avoided). The John Hopkins medical dictionary defines it as: /de·can·nu·la·tion/ (de-kan″u-la´shun) extubation of a cannula. That helped, didn't it? Not even! In a nutshell, it is the process of removing a tracheotomy tube (a ventilator) which has to be done carefully and the patient needs to meet a certain breathing criteria before it can be done. Tricky stuff. Most of the images were of children.

Anyway, I thought it an interesting word. If, in your life experiences, someone you love has a tracheotomy or put on a ventilator, read up on decannulation and the criteria that needs to be met before removed.  I found the information to be very helpful and I hope I don't really need to use in my future-but, if I do, at least I am empowered with the information.

Wonderful post. Thanks for the doppler piece. Very cool. And, I HAVE been to Dayton (Ohio), and am pleased to say that its Downtown is actually experiencing a wonderful rebirth.

Thanks for the info on the Doppler Effect; most interesting!!

Whew, its always an adventure coming here.
Thanks for the Doppler info. I only knew about the radar.
I have never been to either of the downtowns so this photo could have been from anywhere..(:0)

I recall you always had an eclectic post of pics for abc. Very interesting Doppler effect.

I I LIKE LIKE YOUR YOUR DOUBLE DOUBLE EXPOSURE EXPOSURE

But I had never heard that word; serious issue.

Great post with many interesting D- words. The Doppler effect is really amazing. You often hear this when a siren of an ambulance is sounding.
I have learnt again something new.

Okay, so a prone patient who has been intubated can be extubated via decannulation if turned too quickly. I'll try to remember that if anyone ever wants to involve me in turning a patient, but it's highly unlikely.
I wonder if my camera will take double exposures. I used to do that with my little black and white camera when I was 10 or 12. I'd have a friend stand in front of a white wall, and I'd take her picture, then I'd have her move two feet over, and I'd take another, without winding the film in between. So I'd create twin friends. My camera and I were very popular for a while until I had doubled the population of the neighborhood and everyone got bored with it.

I love that double exposure - it's a nifty thing to do with a camera rather than the computer. Downtown Albuquerque. It's been years since I've visited there - it's a beautiful part of the world.

I misread "extubation of a cannula" as "excavation of a cannoli," something with which I am quite familiar! This was an interesting post, filled with info and images. I didn't know you could "force" a double image via camera. Your results are beautiful. Have missed you during my hiatus! Peace, Amy
