Recent ground networks and satellite remotesensing observations have provided useful data related to spatial and vertical distributions of mineral dust particles in the atmosphere. However, measurements of temporal variations and spatial distributions of mineral dust deposition fluxes are limited in terms of their duration, location, and processes of deposition. To ascertain temporal variations...

Climate-induced changes in regional precipitation could have important implications for the carbon, water, and nutrient cycles of forest ecosystems. However, few studies have examined the response of deciduous forests to increases or decreases in precipitation. Therefore, the throughfall displacement experiment (TDE) was established in 1993 near Oak Ridge, Tennessee to examine the sensitivity o...

in order to prevent the shrinkage of olive fruit and maintain its fresh being, and  also to increase the oil content and dry matter, the effect of kaolin at three levels of application (0, 2.5% and 5%) on four varieties of olive (mission, conservolea, keillet, blady) was evaluated within a period of four months, in ahwaz, the tests being repated in 3 replicates. results revealed significant eff...

The oxidation kinetics of reactively sputtered amorphous Tas&Si;,NSe thin films are studied in dry and wet ambient in the temperature range of 650-850 “C by backscattering spectrometry, Dektak profilometer, and x-ray diffraction analyses. The dry oxidation is. well described by a parabolic time dependence which corresponds to a process controlled by the diffusion of the oxidant in the oxide. Th...

Background: The old concept of total-etch/dry bonding has been superseded by total-etch/wet bonding, and later on by the self-etch systems. Manufacturers have introduced single bottle systems to be used in total-etch, self-etch, or selective-etch modes under both dry and moist conditions. The aim of this study was to evaluate shear bond strengths of three different dental adhesives under dry an...

We have performed numerical simulations of the atmosphere for typical daytime convective conditions at Chajnantor, and derived the resulting wet and dry contributions to the atmospheric phase fluctuations. The simulations show that: ◦ Dry phase fluctuations are concentrated in two layers – near to the ground, and at the temperature inversion. The wet fluctuations are concentrated at the inversi...

A pure Silicate host namely Sr2MgSi2O7 as a support for a long-lasting afterglow when dopped with rare-earth elements was sought after. To this end the process of obtaining firing temperatures of the above mentioned phase in normal condition was carried out using suggested wet and dry methods. The degree of purity obtained in these preparatory methods as wel...
