A review with comprehensive data on experimental indirect scalar NMR spin-spin coupling constants across hydrogen bonds

Description: Scalar NMR spin-spin coupling constants across hydrogen bonds are fundamental in structural studies and as test grounds for theoretical calculations. Since they are scattered among many articles of different kinds, it seems useful to collect them in the most comprehensive way. Copyright © 2008 John ...

Biodegradable gelatin-chitosan films incorporated with essential oils as antimicrobial agents for fish preservation

Description: Essential oils of clove (Syzygium aromaticum L.), fennel (Foeniculum vulgare Miller), cypress (Cupressus sempervirens L.), lavender (Lavandula angustifolia), thyme (Thymus vulgaris L.), herb-of-the-cross (Verbena officinalis L.), pine (Pinus sylvestris) and rosemary (Rosmarinus officinalis) were tes...

On the numerical determination of Dunham's coefficients: An application to X1Σ+HCl isotopomers

Description: Rovibrational transition energies of the centrifugally distorted oscillator for the manifold of the HCl isotopomers are computed by means of an efficient variational-numerical method. The starting points are the potential energy surface determined using highly correlated ab initio calculations (RCCS...

Whole-genome analysis with SNPs from BOPA1 shows clearly defined groupings of Western Mediterranean, Ethiopian, and Fertile Crescent barleys

Description: 29 Pags., 3 Tabls., 3 Figs, 2 Supplement. Mat. The definitive version is available at: http://link.springer.com/journal/10722 , The discovery of Hordeum spontaneum C. Koch, a wild ancestor of cultivated barley, in Morocco in 1978 led to the proposal of a multicentric origin for this crop, as an altern...

Influence of traffic distribution on some metal contents in urban soils: "urban" and "natural" elements

Description: In contrast with soils in agricultural areas, soils in urban areas (particularly in parks and gardens) have a direct infl uence on public health not related with production of food. This is due to the fact that it can come easily in contact with humans and be transferred to them, either as suspended...

Impaired trafficking and activation of tumor necrosis factor-α-converting enzyme in cell mutants defective in protein ectodomain shedding

Description: Protein ectodomain shedding is a specialized type of regulated proteolysis that releases the extracellular domain of transmembrane proteins. The metalloprotease disintegrin tumor necrosis factor-α-converting enzyme (TACE) has been convincingly shown to play a central role in ectodomain shedding, bu...

A study in desmotropy

Description: A solid-state NMR/theoretical study of the tautomerism of 4-substituted pyrazolinones was carried out in search of new desmotropes. Thus, the systematic exploration by 13C and 15N CPMAS NMR of a series of 4-acylpyrazolin-5-ones has allowed to determine their structure in the solid state and to find ...

Sorption-desorption of PB(II) by model associations of soil colloids

Description: Natural colloids are organomineral associations of multiple soil constituents, which are the main contributors to sorption and transport processes affecting contaminants in soil and water. The importance of individual soil constituents on contaminants sorption is usually evaluated by studying the so...

Semiclassical formulation of the unimolecular multiphoton dissociation. Dressing of energy levels of the active mode.

Description: Using the minimum coupling Hamiltonian for deascribing the system active mode-laser fields, we have calculated the shifts of the energy levels of the active mode, produced by thr intense laser fields, by means of a methods upon a space-translation transformation. The laser field has been considered ...
