And meteoriticists that study this refractory stardust extracted from meteorites often call it presolar grains, although the refractory stardust that they study is actually only a small fraction of all presolar dust. Stardust condenses within the stars via considerably different condensation chemistry than that of the bulk of cosmic dust, which accretes cold onto preexisting dust in dark molecular clouds of the galaxy.

In the past scleroderma renal crisis was almost uniformily fatal. While outcomes have improved significantly with the use of ACE inhibitors the prognosis is often guarded, as a significant number of patients are refractory to treatment and develop renal failure.
It also has the advantage of being less toxic than other drugs used for treating refractory ovarian cancer.
It is effective in treating refractory post-stroke pain, atypical face pain, anaesthesia dolorosa, and deafferentation and somatic pain such as in phantom limb or brachial plexus injury (Boccard et al. 2013).
It is produced during various melting and firing processes, and is used as a refractory material, due to its high melting point of 1840°C. In 2006 researchers at University College London and Cardiff University discovered that potters in the Hesse region of Germany since the late Middle Ages had used mullite in the manufacture of a type of crucible (known as Hessian crucibles), that were renowned for enabling alchemists to heat their crucibles to very high temperatures.
It is used to treat refractory ovarian cancer.
Nor is there any need of transporting them beyond seas, for if any are refractory they should be sent to our stannaries and other mines, to our coal works and other places where hard labour is required.
On the other hand, grains are seen to have recently formed in the vicinity of nearby stars, in nova and supernova ejecta, and in R Coronae Borealis variable stars which seem to eject discrete clouds containing both gas and dust. So mass loss from stars is unquestionably where the refractory cores of grains formed.
Phase II clinical trials in adult patients with refractory partial seizures were promising.
Pierre Dumoulin-Borie had as a godfather his uncle Pierre Borie, a priest refractory during the Revolution, and then curé of Sionac; but an uncle, Jean Borie, was an administrator of Corrèze, deputy in the Legislative Parliament and Convention, and one of those who voted for the death of Louis XVI.

Recurrent or refractory bleeding may lead to need for surgery, although this has bencome uncommon as a result of improved endoscopic and medical treatment.
Refractory bricks are designed in several layers.
Refractory bricks are typically replaced every five years, because thermal fatigue gradually introduces fissures that reduce the insulating strength.
Refractory xenocrysts (olivine, orthopyroxene, spinel) from Level Mountain basalt and spinel lherzolites from nearby vents in the Stikine Canyon and at Castle Rock support this contention.
Seclusion rooms and refractory wards were used for resistive patients, even when their forms of resistance were non-violent.
Several percent of refractory grain cores have condensed within expanding interiors of supernovae, a type of cosmic decompression chamber.
Some molecules also formed complex organic compounds and some molecules formed frozen ice mantles, of which either could coat the "refractory" (Mg, Si, Fe) grain cores.
Stardust grains are solid refractory pieces of individual presolar stars.
Stardust once more provides an exception to the general trend, as it appears to be totally unprocessed since its thermal condensation within stars as refractory crystalline minerals.

The volatile elements have never seen temperatures above about 500 K, therefore, the IDP grain "matrix" consists of some very primitive Solar System material. Such a scenario is true in the case of comet dust. The provenance of the small fraction that is stardust (see above) is quite different; these refractory interstellar minerals thermally condense within stars, become a small component of interstellar matter, and therefore remain in the presolar planetary disk.
There are more than twenty deposits of refractory and fireclay.
These refractory mineral grains may earlier have been coated with volatile compounds, but those are lost in the dissolving of meteorite matter in acids, leaving only insoluble refractory minerals.

Women are able to achieve multiple orgasms due to the fact that they generally do not require a refractory period like men do after the first orgasm; though generally reported that women do not experience a refractory period and thus can experience an additional orgasm, or multiple orgasms, soon after the first, some sources state that both men and women experience a refractory period because women may also experience a period after orgasm in which further sexual stimulation does not produce excitement.
