Invasive technologists are part of a team in a cardiac catheterization laboratory, with a working knowledge of ECG interpretation, coronary anatomy, physiology and disease mechanisms, and cardiovascular pharmacology. Choose an accredited certificate or degree program. Several schools offer programs for a certificate of cardiovascular technology or associate's or bachelor's of health science degrees. These programs are administered through classroom instruction, practical laboratory application and clinical work.
Planting trees by the thousands. If you have maple trees around your house, you are familiar with the seeds that helicopter down from the trees filling your rain gutters and generally making a mess. The next time you are complaining about these nasty little irritations, take time to look at one carefully.
A close examination of leaves on the ground will likely show leaves with only a small portion of their stems (petiole). This leaf drop is caused by the feeding of maple petiole borers, Caulocampus acericaulis. Petiole borers are small insects called sawflies, which are non-stinging wasps. The sawfly is only about 1/6 of an inch long and emerges from the soil in the spring to mate and lay eggs near the base of the petiole of maple leaves.
