Another, more interesting, criticism, of stealth in space is that not everyone will have access to a proper set of space surveillance equipment, which could allow stealth to work. This is obviously true. A civilian craft is not likely to be plugged into the space surveillance network, nor will any potential pirates or other low-level ne’er-do-wells. For that matter, a small colony may not have a sensor setup beyond that needed for local control. If there is only one possible point of detection, then directional radiation becomes at least partially effective, and burns might be able to be hidden from the target by careful trajectory design. Besides not having remote sensors to catch directional radiation, the targets in these cases would not have capable sensors of their own, and might rely on transponder data except at very close range.
Additionally, one problem for collecting bone marrow stem cells is that the area at the back of the hip where they are harvested has some pitfalls. If the doctor performs this type of collection without imaging guidance (blind without using either fluoroscopy or ultrasound), the chance of taking cells from the wrong area goes up dramatically. In this area of the back of the hip, there’s a paper thin part of the pelvis that if tapped by the doctor, will almost always result in a blood collection only, rather than a bone marrow aspirate. Precision is the key to a Regenexx physician’s ability to maximize stem cells during the harvesting procedure. Close Regenexx Procedures
I have been using Bydureon for 8 weeks now and I have 7 nodules under my skin at the injection sites. The first few weeks I didn't notice them and one day I felt a large bump. When I started feeling around I felt more. Then I began observing the process. I would inject and end of the day the area around the injection site would appear white, then the next day it would be red and start itching! Then the lump would start forming. So currently I have seven lumps under my skin. A few of them are quite large and some very noticeable visibly without feeling for them. I still get pretty nauseus and indigestion often. Sometimes severely other times mildly. My doctor has taken me off the Bydureon and prescribed Victoza. I don't know if these nodules under the skin are harmful or not. If you or anyone finds this out, lease let me know. Thanks!
