the paper presents the results of an investigation on the acoustic performance of vertical profile parallel barriers with quadratic residue diffuser tops and faces. a 2d boundary element method (bem) was used to predict the barrier insertion loss. the results of rigid and with absorptive coverage were also calculated for comparisons. using qrd on the top surface and faces of all vertical profil...

This notion is true for a perfect elastic body. Because the lungs do not present perfect elastic behavior, the relationship among V, compliance, and P is not linear along all the vital capacity range, as showed by Eq. 1. When the respiratory system is subjected to P, time is needed until V occurs, and the time necessary to inflate 63% of its volume is called the time constant ( ) (3). It descri...

pollen grains as well as whole plants of four olive (olea europaea l.) cultivars were screened for nacl salinity stress. different vegetative and physiological indexes of the cultivars were analyzed. leaf and root na/k ratio as well as stomatal resistance of plants exposed to salinity proved to be appropriate indexes of whole plant response to salt stress. whereas, in vitro pollen germination p...

Occurrence of Hysteresis like behavior of resistance of Sb 2 Te 3 film in heating-cooling cycle. Abstract Experimental observations of a peculiar behavior observed on heating and cooling Sb 2 Te 3 films at different heating and cooling rate are detailed. The film regained its original resistance, forming a closed loop, on the completion of the heating-cooling cycle which was reproducible for id...

Increasing the cross-sectional area of piles or adding wings to are two strategies for increasing bearing capacity resist lateral stresses. Small and full-scale finite element models were used investigate effect on laterally loaded pile in this study. Four embedded ratios (4, 6, 8, 10) with various wing dimensions numbers. The results showed that increases resistance loads reduces displacement ...

Members of a gene family expressed in a single species often experience common selection pressures. Consequently, the molecular basis of complex adaptations may be expected to involve parallel evolutionary changes in multiple paralogs. Here, we use bacterial artificial chromosome library scans to investigate the evolution of the voltage-gated sodium channel (Nav) family in the garter snake Tham...

UNLABELLED Activation of fibroblast growth factor receptors (FGFR) is a common oncogenic event. Little is known about the determinants of sensitivity to FGFR inhibition and how these may vary between different oncogenic FGFRs. Using parallel RNA interference (RNAi) genetic screens, we show that the EGF receptor (EGFR) limits sensitivity to FGFR inhibition in FGFR3-mutant and -translocated cell ...
