Monazite was the only significant source of commercial lanthanides, but because of concern over the disposal of the radioactive daughter products of thorium, bastnäsite came to displace monazite in the production of lanthanides in the 1960s due to its much lower thorium content.
In cases of short duration, there may be small blisters, while in long-term cases the skin may become thickened. [149] The area of skin involved can vary from small to the entire body. [149] [150] Diagnosis – Medical diagnosis (abbreviated Dx [151] or D S) is the process of determining which disease or condition explains a person's symptoms ...
Tinea corporis (also known as "ringworm", [2] tinea circinata, [11] and tinea glabrosa [2]) is a superficial fungal infection (dermatophytosis) of the arms and legs, especially on glabrous skin; however, it may occur on any part of the body, it present as annular, marginated plaque with thin scale and clear center.
Poikiloderma vasculare atrophicans, or PVA, indicates that extra or altered skin pigmentation ("poikiloderma") [10] is occurring, associated with heightened visibity of capillaries ("vasculare", referring to telangiectasia) under the skin, related to thinning and wasting away ("atrophicans") of the skin and its tissue. Telangiectasia is an ...
Medical terminology is a language used to precisely describe the human body including all its components, processes, conditions affecting it, and procedures performed upon it. Medical terminology is used in the field of medicine .
Anatomical terminology is a specialized system of terms used by anatomists, zoologists, and health professionals, such as doctors, surgeons, and pharmacists, to describe the structures and functions of the body. This terminology incorporates a range of unique terms, prefixes, and suffixes derived primarily from Ancient Greek and Latin.
There is little difference in the three in terms of physical properties and most bastnäsite is bastnäsite-(Ce). Cerium in most natural bastnäsites usually dominates the others. Bastnäsite and the phosphate mineral monazite are the two largest sources of cerium, an important industrial metal. Crystal structure of bastnäsite-(Ce).
It is the cerium-dominant analogue of monazite-(La), monazite-(Nd), and monazite-(Sm). It is also the phosphorus analogue of gasparite-(Ce). [ 3 ] The group contains simple rare earth phosphate minerals with the general formula of AXO 4 , where A = Ce, La, Nd, or Sm (or, rarely, Bi), and X = P or, rarely, As.
