08-1 mm thick samples, thinned from bulk material. Unlike past work on thicker samples, thin 1050 Al samples reveal large and rapidly attenuating elastic wave amplitudes, indicating a time-dependent elastic-plastic response. Extrapolation of measured elastic wave amplitudes to larger sample thicknesses agrees well with previously observed amplitudes for thicker 1050

and 1060 Al samples. Thus, all of the results for relatively pure polycrystalline Al can be reconciled into a single consistent picture: elastic wave attenuation, due to time-dependent elastic-plastic response, is confined to material close to the impact Duvelisib in vitro surface. In contrast to the 1050 Al results, thin 6061-T6 Al samples reveal an elastic wave amplitude of similar to 0.7 GPa with no attenuation, in quantitative agreement with previous results for thick 6061-T6 Al samples. The lack of elastic wave attenuation even in thin samples suggests

that elastic wave amplitudes in shocked 6061-T6 Al are governed by different plastic deformation mechanisms than those for shocked pure Al. (C) 2009 American Institute of Physics. [doi:10.1063/1.3236654]“
“The objective of this study is to analyze volatile compounds from different types of vegetable oils under light emitting diode (LED) irradiation during 12 weeks. Yellow, red, blue, and fluorescent light were treated by LED equipment. Samples Selleckchem BKM120 stored

under dark conditions were also conducted at the same time. A MS-based electronic nose and see more discriminant function analysis (DFA) were used to determine the amount of volatiles from various oils under LED irradiation. As the exposure time of LED treatment increased, volatile compounds in sesame oil and perilla oil increased considerably under blue light. Under fluorescent, red, and yellow light, the volatile compounds from extra virgin olive oil increased significantly.”
“Dehydrins have a key role in protecting plants from dehydration stress. We report here the isolation of two cDNAs coding for the same dehydrin, AmDHN1 and AmDHN1a from salt stressed leaves of Avicennia marina (Forsk.) Vieth. by EST library screening. AmDHN1 was found to contain a retained intron that was absent in AmDHN1a. AmDHN1 expression in the context of various environmental stresses was investigated. In leaves, AmDHN1 shows a diurnal pattern of regulation and is induced only by mannitol application. in roots, AmDHN1 is rapidly induced by salinity (NaCl) and dehydration stress (PEG and mannitol). A fragment of 795 bp corresponding to the 5′ upstream region of AmDHN1 was isolated by TAIL-PCR. In silico analysis of this sequence reveals the presence of putative stress regulatory elements (ABRE, DRE, MYB and MYC binding sequences).
