Since MURS uses standard frequencies, most devices that use MURS are compatible with each other. Most analog two-way radios utilize a technology called CTCSS or DCS that helps block out unwanted transmissions. To make MURS two-way radios work together, they must have matching CTCSS or DCS tones. This can usually be done via basic programming ...
A low intensity (ISPTA < 5 W/cm2) pulsed ultrasound (LIPSA) approach can exploit the mechanical properties of neoplastic cells to target them for destruction. Ultrasound applied at a frequency of 0.5–0.67 MHz for >20 ms causes selective disruption of a panel of breast, colon, and leukemia cancer cell models in suspension without significantly damaging healthy immune or red blood cells.
In principle, this approach could be selective for cancer cells in regions of the body, such as the brain, where the majority of normal cells are non-proliferating. [11] The frequency of the TTField can be adjusted between 100 and 300kHz to target cancer cells and avoid harming healthy cells.
Radio frequencies at non-ablation energy levels are commonly used as a part of aesthetic treatments that can tighten skin, reduce fat by lipolysis and also apoptosis, [4] or promote healing. [5] RF diathermy is a medical treatment that uses RF induced heat as a form of physical therapy and in surgical procedures. It is commonly used for muscle ...
The FCC has restricted the frequencies allowed for medical treatment, and most machines in the US use 27.12 MHz. [26] Shortwave diathermy can be applied in either continuous or pulsed mode. The latter came to prominence because the continuous mode produced too much heating too rapidly, making patients uncomfortable.
Like CB, MURS frequencies may be used for business or personal/family communications. Two of these frequencies were re-allocated from the Business/Industrial Radio Pool ( Business Radio Service ). These two frequencies were often used illegally by businesses as they were/are part of the "color dot" frequencies that handheld "on-site" business ...
