Raman spectra of ice VII and X were investigated using strong plasma shockwave generated by laser-induced breakdown (LIB) in liquid water. Simultaneously, the occurrence of the hydrogen emission lines of 656 nm (Hα), 486 nm (Hβ), 434 nm (Hγ) and 410 nm (Hδ) was observed. At 5 × 10(12) W/cm(2) optical power density, the O-H symmetric stretching, translational and librational modes of ice VII and...

The objective of this study was to determine the appropriate non-linear function describing growth of some testicular traits (testicular length, testicular diameter, scrotal circumference and scrotal length) in Norduz male lambs. Testicular characteristics at 90, 110, 130, 150, 170, and 190 days of age for all the lambs were measured. Four growth (Monomolecular, Logistic, Gompertz, and Richard’...

One of enduring problems of phospholipid adsorption at the interface between two immiscible electrolyte solutions (ITIES) has been the inability to determine and control the exact nature of the adsorbed monomolecular layer. In the present study, this problem has been overcome by the use of the well-known Langmuir-Blodgett technique. It has been shown that reproducible layers of known surface pr...

A major challenge in neuroscience is relating neuronal activity to animal behavior. In olfaction limited techniques are available for these correlation studies in freely moving animals. To solve this problem, we developed an olfactory behavioral assay in head-restrained mice where we can monitor behavioral responses with high temporal precision. Mice were trained on a go/no-go operant condition...

I t is a common observation of dairymen that the milk flow of the dairy cow rises for some time after calving and then declines steadily. In preceding papers 1 we have presented data and have offered an interpretation for the declining segment of the curve of milk secretion. Having found that after the first month of lactation the curve of milk secretion with the advance of the period of lactat...

Modified sorption materials were produced by treating earleaf acacia ( Acacia auriculiformis ) bark with low-concentration (1-3%wt) sulfuric acid solutions. The properties of native and modified for zinc (II) ions studied. Based on the values initial equilibrium concentrations in solution, materials' capacity (A, mmol/g) was found adsorption isotherms plotted. It that are type I according to IU...
