This thesis describes the construction of a versatile apparatus to study ultracold quantum mixtures capable of simultaneously cooling fermionic Li and K, as well as the bosonic K. The main features of the experimental setup are presented, in particular the addition of a new species Na, which has enabled the study of the Bose-Fermi mixture Na-K. Three main experimental benchmarks are outlined: f...
FXYD proteins, small single-transmembrane proteins, have been proposed to be auxiliary regulatory subunits of Na(+)-K(+)-ATPase and have recently been implied in ion osmoregulation of teleost fish. In freshwater (FW) fish, numerous ions are actively taken up through mitochondrion-rich cells (MRCs) of the gill and skin epithelia, using the Na(+) electrochemical gradient generated by Na(+)-K(+)-A...
We report on the formation of ultracold fermionic Feshbach molecules of NaK, the first fermionic molecule that is chemically stable in its ground state. The lifetime of the nearly degenerate molecular gas exceeds 100 ms in the vicinity of the Feshbach resonance. The measured dependence of the molecular binding energy on the magnetic field demonstrates the open-channel character of the molecules...
feldspar grains, as a significant provenance indicator, of two terrigenous formations from central iran, the upper red formation, and moghan area, zivah formation, are used for provenance determination and the study of transportation and depositional history. the upper red formation (urf) is volumetrically the most important siliciclastic unit of the central iran and zivah formation (zf) repres...
Calcium permeability and the concomitant calcium block of monovalent ion current ("Ca(2+) block") are properties of cyclic nucleotide-gated (CNG) channel fundamental to visual and olfactory signal transduction. Although most CNG channels bear a conserved glutamate residue crucial for Ca(2+) block, the degree of block displayed by different CNG channels varies greatly. For instance, the Drosophi...
Reperfusion injury results from pathologies of cardiac myocyte physiology that develop when previously ischemic myocardium experiences a restoration of normal perfusion. Events in the development of reperfusion injury begin with the restoration of a proton gradient upon reperfusion, which then allows the sodium-proton exchanger (NHE) to increase flux, removing protons from the intracellular spa...
The chemical, morphological and mineralogical properties of two Enon sandy loam (fine, mixed, thermic Ultic Hapludalfs) soilsaprolite profiles, one formed on gabbro and the other on metagabbro, are compared. Clay skins are scarce and stress cutans common in the argillic horizons of these soils. Iron-manganese concretions are concentrated in soil horizons immediately above the argillic horizons....
