Traditional transportation fuel, petroleum, is limited and nonrenewable, and it also causes pollutions. Hydrogen is considered one of the best alternative fuels for transportation. The key issue for using hydrogen as fuel for transportation is hydrogen storage. Lithium nitride (Li3N) is an important material which can be used for hydrogen storage. The decompositions of lithium amide (LiNH2) and...

The effects of irrigation and planting pattern on wheat in field conducted at Taian, northern China during 2011-12. The experiments consisted of two planting patterns (single and double rows) and two irrigation levels (0 and 180 mm) resulting in the same plant density (200 × 10 plant/ha). Each experiment plot was 3 m × 3 m in size and replicated thrice in split-plot design. During course of stu...

A DFT study of U(VI) hydroxy complexes was performed with special attention paid to the [(UO2)3(OH)5(H2O)4-7]+ and [(UO2)4(OH)7(H2O)5-8]+ species. It was established that the ionicity of the U=O bond increased when moving from [(UO2)(H2O)5]2+, [(UO2)2(OH)(H2O)8]3+, [(UO2)2(OH)2(H2O)6]2+, [(UO2)3(OH)5(H2O)4-6]+ to [(UO2)4(OH)7(H2O)5-8]+ species. In both [(UO2)3(OH)5(H2O)4-6]+ and [(UO2)4(OH)7(H2...

The double sigmoidal nature of the mouse pressure-volume (PV) curve is well recognized but largely ignored. This study systematically examined the effect of inflating the mouse lung to 40 cm H2O transrespiratory pressure (Prs) in vivo. Adult BALB/c mice were anesthetized, tracheostomized, and mechanically ventilated. Thoracic gas volume was calculated using plethysmography and electrical stimul...

The deuterium isotope effect in the steady state CO oxidation rate over Au/ -Al2O3 in the presence of H2 or H2O and the effect of pretreatment on an uncalcined catalyst were studied. In a reaction feed containing 1% CO, 0.5% O2, and 40.5% H2 at room temperature, CO oxidation exhibited a deuterium isotope effect (kH/kD) of 1.4 ± 0.2. The rate of D2 oxidation was also slower than the oxidation of...

The aim of the present study was to develop and validate the Children's Depression Screener (ChilD-S) for use in pediatric care. In two pediatric samples, children aged 9-12 (N(I) = 200; N(II) = 246) completed an explorative item pool (subsample I) and a revised item pool (subsample II). Diagnostic accuracy of each of the 22 items from the revised pool was evaluated in order to select the best ...

We report spectroscopy of clusters of guanine base pairs with one and two water molecules. We recorded the vibronic spectra of the mass-selected GG(H2O) and GG(H2O)2 clusters using resonant two photon ionization (R2PI) and we used IR-UV double resonance spectroscopy to obtain ground state IR spectra of these clusters. We found that a single water molecule stabilizes one of two structures we had...

Ab initio calculations using the UMP2 and UQCISD methods with correlation consistent double-zeta and triple-zeta basis sets were applied to study the reactions of HNO with H and OH radicals. The classical energy barrier for the abstraction H+HNO!H2 +NO is 0.5 kcal/mol. The reaction path of OH+HNO is: OH+HNO!HNO(OH)-complex!TS!NO(H2O)complex!H2O+NO with no energy barrier relative to OH+HNO entra...
