Plasma oscillations, also known as Langmuir waves (after Irving Langmuir), are rapid oscillations of the electron density in conducting media such as plasmas or metals in the ultraviolet region. The oscillations can be described as an instability in the dielectric function of a free electron gas. The frequency depends only weakly on the ...
The Langmuir wave is a purely longitudinal wave, that is, the wave vector is in the same direction as the E-field. It is an electrostatic wave; as such, it doesn't have an oscillating magnetic field. A plasma consists of charged particles which react to electric fields, in contrast with dielectric matter.
Waves in plasmas can be classified as electromagnetic or electrostatic according to whether or not there is an oscillating magnetic field. Applying Faraday's law of induction to plane waves , we find k × E ~ = ω B ~ {\displaystyle \mathbf {k} \times {\tilde {\mathbf {E} }}=\omega {\tilde {\mathbf {B} }}} , implying that an electrostatic wave ...
The charge density oscillations and associated electromagnetic fields are called surface plasmon-polariton waves. The exponential dependence of the electromagnetic field intensity on the distance away from the interface is shown on the right. These waves can be excited very efficiently with light in the visible range of the electromagnetic ...
Romosozumab, sold under the brand name Evenity (/ ɪ ˈ v ɛ n ɪ t i / ih-VENN-ih-tee or with the pin-pen merger, / ɪ ˈ v ɪ n ɪ t i / ih-VINN-ih-tee), is a medication used to treat osteoporosis. [7] [8] It has been found to decrease the risk of fractures of the spine. [7] Common side effects include headache, joint pain, and injection site ...
Long-term treatment with bisphosphonates produces anti-fracture and bone mineral density effects that persist for 3–5 years after an initial 3–5 years of treatment. [2] The bisphosphonate alendronate reduces the risk of hip, vertebral, and wrist fractures by 35-39%; zoledronate reduces the risk of hip fractures by 38% and of vertebral ...
Clodronic acid or clodronate disodium (Na 2 CH 2 Cl 2 O 6 P 2) is a first generation (non-nitrogenous) bisphosphonate.It is an anti-osteoporotic drug approved for the prevention and treatment of osteoporosis in post-menopausal women and men to reduce vertebral fractures, hyperparathyroidism, hypercalcemia in malignancy, multiple myeloma and fracture related pain because of its anti ...
Even though the plasma may look continuous, it is actually a series of ionization waves or "plasma bullets". [14] This ionization wave may or may not treat the tissue being treated. Direct contact of the plasma with the tissue or sample can result in dramatically larger amounts of reactive species, charged species, and photons being delivered ...
