“…The off-diagonal terms of H 1Q are classified into two types. The coupling between the oscillators of different molecules [48][49][50][51][52] is assumed to be determined by the transition dipole coupling (TDC) mechanism, [20][21][22][23][24]53,54 expressed as where T mn is the dipole interaction tensor between the mth and nth oscillators, which is given as where r mn ) r mr n is the distance vector (of length r mn ) between the two oscillators, and I is a 3 × 3 unit tensor. Equation 14 applies to hydrogen-bonded as well as distant pairs of molecules, meaning that the present method deals with the vibrational interactions between all the pairs of molecules in a unified way, rather than assuming a special interaction mechanism for hydrogen-bonded pairs.…”

The polarized Raman spectrum and the time dependence of the transient infrared (TRIR) absorption anisotropy are calculated for the OH stretching mode of liquid water (neat liquid H2O) by using time-domain formulations, which include the effects of both the diagonal frequency modulations (of individual oscillators) induced by the interactions between the dipole derivatives and the intermolecular electric field, and the off-diagonal (intermolecular) vibrational coupling described by the transition dipole coupling (TDC) mechanism. The IR spectrum of neat liquid H2O and the TRIR anisotropy of a liquid mixture of H2O/HDO/D2O are also calculated. It is shown that the calculated features of these optical signals, including the temperature dependence of the polarized Raman and IR spectra, are in reasonable agreement with the experimental results, indicating that the frequency separation between the isotropic and anisotropic components of the polarized Raman spectrum and the rapid decay (approximately 0.1 ps) of the TRIR anisotropy of the OH stretching mode of neat liquid H2O are mainly controlled by the resonant intermolecular vibrational coupling described by the TDC mechanism. Comparing with the time evolution of vibrational excitations, it is suggested that the TRIR anisotropy decays in the time needed for the initially localized vibrational excitations to delocalize over a few oscillators. It is also shown that the enhancement of the dipole derivatives by the interactions with surrounding molecules is an important factor in generating the spectral profiles of the OH stretching Raman band. The time-domain behavior of the molecular motions that affect the spectroscopic features is discussed.

“…Bacteria is able to reduce sulfate by assimilatory sulfate reduction to sulfate reduction to sulfide and to integrate in to Cysteine in the cytosol. [14], Cysteine had substantial influence on photosynthetic pigments and enzymes activities in the plants, [12], advocated the previous results, they found that treating wheat plants with Cysteine at the rate of 10-4 M was partially effective for ameliorating the harmful effect of heat temperature stress on photosynthetic pigments and the determined enzymes activities of wheat plants.…”

Three pot experiments were carried out at Agric. Res. Station, Fac. Agric., Al-Azhar Univ. Nasr City during 2011/2012, 2012/2013 seasons, each one was to investigate the effect of four un mineral package for each N, P and K on quality of three wheat Egyptian varieties, such as, Sakha-93, Masr-1 and Banisweif-6. The N package were 75 kg N/fed (control), 75 kg N/fed + the twice cysteine spraying (each 150 ppm), 37,5 kg N/fed + bio N fertilizer (cerialen) + the twice cysteine spraying and 37,5 kg N/fed + bio N fertilizer (biogen) + the twice cysteine spraying. The p fertilizer packages were phosphorine, humic acid 6%, phosphorine+ humic 6% acid and control (without P). The K fertilizer package were Potassiumage, Banana ash 4%, Potassiumage + Banana ach 4% and control (without K fertilizer). On the other hand, a field experiment was applied in 2013/2014 session at El Klag region, Kaliobia Governorate, Egypt to confirm the result gaved from the pot experiments. However pot experiments were designed in complete randomizes design, the field experiment was in split plot design. Results showed significant differences between the three tested wheat varieties such as grain protein contents, wet and dry gluten content. Baniswif-6 gave grains quality characters higher than Sakha-93 and Masr-1 varieties in cache season under pot and field experiments. Technological properties were differed significantly between the studied nitrogen fertilizers packages treatments during the three growing seasons under pot or field experiments. In the second experiments, there were significant differences between the various phosphorus fertilizer packages treatments in both seasons under pot and field experiments. P4 and P3 treatments recorded the highest values of technological properties as compared with P1 treatment in the three seasons in pot or field experiments. The interaction effect between (var. X P. packages) showed that must of the studied characters were significant by the interaction between the two studied factors. Finally, in the third experiment, significant differences were observed between the four studied potassium fertilizers packages for all studied characters under pot and field experiment in both seasons, whereas K4 treatments gave the highest values of technological characters. Also K3 treatment ranked the second and produced the highest values of the previous traits in both seasons. Accordingly, the three wheat varieties showed highest responsibility to different N, P and K fertilizer packages in relation to some technological properties in pot or field experiments under these conditions
