Uranium dioxide or uranium(IV) oxide (UO 2), also known as urania or uranous oxide, is an oxide of uranium, and is a black, radioactive, crystalline powder that naturally occurs in the mineral uraninite. It is used in nuclear fuel rods in nuclear reactors. A mixture of uranium and plutonium dioxides is used as MOX fuel.
Mometasone, also known as mometasone furoate, is a steroid (specifically, a glucocorticoid) medication used to treat certain skin conditions, hay fever, and asthma. [ 10 ] [ 11 ] [ 12 ] Specifically it is used to prevent rather than treat asthma attacks. [ 10 ]
[1] Phase relationships in the uranium-oxygen system are complex. The most important oxidation states of uranium are uranium(IV) and uranium(VI), and their two corresponding oxides are, respectively, uranium dioxide (UO 2) and uranium trioxide (UO 3). [2] Other uranium oxides such as uranium monoxide (UO), diuranium pentoxide (U 2 O 5), and ...
Topical steroids are the topical forms of corticosteroids.Topical steroids are the most commonly prescribed topical medications for the treatment of rash and eczema.Topical steroids have anti-inflammatory properties and are classified based on their skin vasoconstrictive abilities. [1]
Betamethasone is a steroid medication. [3] It is used for a number of diseases including rheumatic disorders such as rheumatoid arthritis and systemic lupus erythematosus, skin diseases such as dermatitis and psoriasis, allergic conditions such as asthma and angioedema, preterm labor to speed the development of the baby's lungs, Crohn's disease, cancers such as leukemia, and along with ...
The metal uranium forms several oxides: Uranium dioxide or uranium(IV) oxide (UO 2, the mineral uraninite or pitchblende) Diuranium pentoxide or uranium(V) oxide (U 2 O 5) Uranium trioxide or uranium(VI) oxide (UO 3) Triuranium octoxide (U 3 O 8), the most stable uranium oxide; yellowcake typically contains 70 to 90 percent triuranium octoxide)
It has been used to treat chronic psoriasis vulgaris [1] and non-infected acute eczematous dermatoses . [2] One study demonstrated that 0.05% halometasone cream was more effective than 0.05% betamethasone cream in treating dermatitis, though both were well tolerated, with no systemic adverse effects reported.
The federal government eventually regulated the standard amount of radon in mines, setting the level at 0.3 WL on January 1, 1969. [28] Out of 69 present and former uranium milling sites in 12 states, 24 have been abandoned, and are the responsibility of the US Department of Energy. [29]
