At low temperatures, the thermodynamic properties of a many-body system are determined by the low energy excursions from the ground state. In quantum degenerate rubidium, the low energy excitations are phonons—phase and density modes—and magnons—spin modes. This thesis reports on the construction of an ultracold rubidium apparatus and techniques to...

Condensate in the exhalation limb of the patient circuit during bubble CPAP can significantly increase pressure delivered to the patient. The back and forth movement of this fluid causes oscillations in airway pressure that are much greater than the oscillations created by gas bubbling out the exhalation tube into the water bath. We recommend conti...

The composition and yield of the products obtained in the underground gasification of coal at Podzemgaz South Abinsk Station are studied. Data are also presented regarding the rectification and hydrocracking of the products. The underground gasification of coal may be regarded as a potential source of phenolic hydrocarbons, naphthalene, pyridine ba...

The assignment (nonstable K0-theory), that to a ring R associates the monoid V( R ) of Murray-von Neumann equivalence classes of idempotent infinite matrices with only finitely nonzero entries over R, extends naturally to a functor. We prove the following lifting properties of that functor: There is no functor Γ, from simplicial monoids with order-...
Import 18/12/2013 / Disertační práce s názvem Životnost tepelných výměníků z Al slitin v prostředí kondenzátů spalin výfukových plynů se zabývá komplexním rozborem zadaného problému. V úvodu je nastíněna problematika přeplňování spalovacích motorů včetně souvislosti s legislativními omezeními, jež vedou k vývoji systémů recirkulace spalin. Ty jsou ...
Diamondoids in crude oil are useful for assessing the maturity of oil in high maturation. However, they are very difficult to separate and accurately quantify by conventional geochemical methods due to their low abundance in oil. In this paper, we use comprehensive two-dimensional gas chromatography with time-of-flight mass spectrometry (GC×GC-TOFM...

An amorphous film of a condensate with large excess energy, configuration entropy, and free volume was prepared from the gas phase on a cold substrate at helium temperatures in the form of vacancies and their aggregates. The temperature dependence of the decomposition of this metastable state at various process stages was studied. The medium is act...
