Evaluated spectroscopic data and level schemes from radioactive decay nuclear reaction studies are presented for 23N, 23O, 23F, 23Ne, 23Na, 23Mg, 23Al, 23Si. This evaluation A=23 supersedes the earlier one by R. B. Firestone (2007Fi02). Highlights of this following: The recommended absolute γ-ray emission probability (%Pγ) in 23Ne β-decay was reported with 3.0% systematic uncertainty 1986BrZQ. ...

This paper describes experiments designed to evaluate Na+ and C1transport in isolated proximal straight tubules from rabbit kidneys. When the perfusing solution was Krebs-Ringer buffer with 25 mM HCO8 (KRB) and the bath contained KRB plus 6 % albumin, net volume reabsorption (J,, nl min-' mm-') was -0.46 4 0.03 (SEM); V., the spontaneous transepithelial potential difference, was -1.13 + 0.05 mV...

22Na+ flux and cytoplasmic pH (pHi) determinations were used to study the reversibility, symmetry, and mechanism of activation of the Na+/H+ exchange system in rat thymic lymphocytes. In acid-loaded cells, the antiport can be detected as an Na+-induced, amiloride-sensitive alkalinization. At pHi greater than or equal to 7.0, amiloride-sensitive net H+ fluxes are not detectable. To investigate w...

One of the goals MICADO Euratom project is to monitor gamma-rays emitted by radioactive waste drums in storage sites on a medium long term basis. For this purpose, 36 low-cost gamma-ray counters were designed and built act as demonstrator. These counters, named SciFi, are based scintillating fiber readout at each end silicon photomultiplier, assembled robust arrangement form 80 cm pipes. Severa...

The role of Na+-H+ exchange in Na+ transport across the apical membrane was evaluated in Necturus gallbladder epithelium by means of intracellular Na+ activity (aNai) and 22Na+ uptake measurements. Under control conditions, complete replacement of Na+ in the mucosal solution with tetramethylammonium reduced aNai from 14.0 to 6.9 mM in 2 min (P less than 0.001). Mucosal addition of the Na+-H+ ex...

We present the first study of the β decay of 23Al undertaken with pure samples. The study was motivated by nuclear astrophysics questions. Pure samples of 23Al were obtained from the momentum achromat recoil separator (MARS) of Texas A&M University, collected on a fast tape-transport system, and moved to a shielded location where β and β-γ coincidence measurements were made. We deduced β branch...

Microsomal sodium and potassium ion-stimulated adenosine triphosphatase ((Na+ + K+)-ATPase) was prepared from canine renal medulla by the method of Kyte. The two polypeptides of the enzyme were co-purified to homogeneity by solubilization with sodium cholate in the presence of egg lecithin and by removal of contaminating protein by sedimentation. This purified (Na+ + I(+)-ATPase was reconstitut...
