For any double lacunary sequence θrs = {(kr, ls)} and an admissible ideal I2 ⊆ P(N×N), the aim of present work is to define the concepts of Nθrs(I2)− and Sθrs(I2)−convergence for double sequence of numbers. We also present some inclusion relations between these notions and prove that Sθrs(I2)∩`∞ and S2(I2)∩ `∞ are closed subsets of `∞, the space of all bounded double sequences of numbers.

We report time-resolved photodissociation and geminate recombination dynamics of I2 2 in size-selected I2 Arn and I2 ~CO2!n cluster ions by using ultrafast pump–probe techniques at 790 nm in conjunction with a tandem time-of-flight mass spectrometer. The absorption recovery, which reflects the time scale for photodissociation followed by recombination and vibrational relaxation of I2 2 inside t...

Plants are frequently subjected to different kinds of stress, such as salinity and, like other organisms, they have evolved strategies for preventing and repairing cellular damage caused by salt stress. Glycine max L. plants were subjected to different NaCl concentrations (0-200 mM) for 10 days. Treatments with 100 and 200 mM NaCl induced ion leakage and lipid peroxidation augmentation, loss in...

The -aminobutyrate B (GABAB) receptor is the first discovered G-protein-coupled receptor (GPCR) that needs two subunits, GB1 and GB2, to form a functional receptor. The GB1 extracellular domain (ECD) binds GABA, and GB2 contains enough molecular determinants for G-protein activation. The precise role of the two subunits in G-protein coupling is investigated. GB1 and GB2 are structurally related...

The X̃ Su 1 state of the I2 2 anion has been fit to a Morse potential using data from two techniques: conventional and femtosecond photoelectron spectroscopy ~FPES!. Conventional photoelectron spectroscopy is used to determine the adiabatic electron affinity of I2 as well as the well depth and equilibrium nuclear geometry of I2 . In the FPES experiment, the pump pulse induces coherent nuclear mo...

Radioligand binding experiments were carried out to identify and characterize nonadrenoceptor [H]idazoxan binding sites and [H](1,2-di-(2-tolyl)guanidine) binding sites in the rat and human stomach. Furthermore, we examined two selected aspects of their potential functional significance. Binding of [H]idazoxan (Kd 5 11.1 nM and 12.4 nM, respectively) and [H]DTG (Kd 5 932 nM and 242 nM, respecti...

The effects of an extracellular sodium (Na) concentration of 200 mM on function, ionic exchange, and water movements were examined in the vascularly perfused rabbit intraventricular septum. When the perfusate was switched from 142 mMNa to 200 mMNa, dP/ dt fell 20.4% over 2 minutes; dP/dt then recovered to the control level. The time course of the functional recovery correlated with the uptake o...
