1.0 overview it seems that grammar plays a crucial role in the area of second and foreign language learning and widely has been acknowledged in grammar research. in other words, teaching grammar is an issue which has attracted much attention to itself, and a lot of teachers argue about the existence of grammar in language teaching and learning. this issue will remind us a famous sentence f...
gol-e-gohar iron ore mine of sirjan in southern part of iran is a large open pit that operates below the groundwater table and during mining operation, dewatering is required to prevent operation processes from flooding. current operation is going on by digging wells in or out of the pit and pumping to prevent flooding. as a result of the former dewatering operation a vast deep cone of depressi...
The compound eye of the Golden Birdwing, Troides aeacus formosanus (Papilionidae, Lepidoptera), is furnished with three types of ommatidia, which are clearly different in pigmentation around the rhabdom. Each ommatidium contains nine photoreceptors, whose spectral sensitivities were analyzed electrophysiologically. We identified nine spectral types of photoreceptor with sensitivities peaking at...
IR spectra of aqueous solutions of P 043-, ADP3-, ATP4-, Mg ADPand (MgADP~ + P 043_) (in two cases hydrated layers) were plotted. The parameter for the investigation was the mole percent of protons relative to the anions. The other cations were sodium or potassium. The purpose of our work was to obtain a basis for understanding the results regarding the changes to the interactions in ATP system...
An abundance analysis for the carbon-enhanced, extremely iron-poor ([Fe/H]∼ −3.5) star CS 29498–043 has been obtained using new high-resolution, high signalto-noise spectra from the Subaru Telescope. The [O I] forbidden line at 6300 Å and the O I triplet feature at 7771-7776 Å are both clearly detected. The overabundance of oxygen is significant ([O/Fe]> 2). In addition, Na, Co, and Ni abundanc...
