Photosynthesis depends upon the absorption of light by pigments in the leaves of plants. The most important of these is chlorophyll-a, but there are several accessory pigments that also contribute.he measured rate of photosynthesis as a function of absorbed wavelength correlates well with the absorption frequencies of chlorophyll a, but makes it evident that there are some other contributors to the absorption.
I recently was catching up with your back podcast episodes and listened to The Man Behind the Maneuver, about Dr. Heimlich and his eponymous life-saving technique. I found it informative, insightful, humorous, and touching. The producer had a deft touch telling Dr. Heimlich's story, as well as his own.
Long answer (before and after Heimlich maneuver): 1  First, if the victim is still breathing (Partial obstruction) â Encourage coughing. 2  When victim cannot cough effectively anymore (and thus cannot breath) â Give x5 back-blows. 3  If the back-blows do not work. â Give x5 abdominal thrusts. Go behind the victim, put your dominant hand around him and place a closed fist right in the middle of the abdomen , just below the rib cage and above the belly button. The fingers that form the OK sign should be touching the abdomen.
