despite the body of research on textbook evaluation from the discourse analysis perspective, cohesive devices have rarely been analyzed in english for specific purposes (esp) textbooks. the acquisition and use of cohesive devices is inherent to naturalistic communication, including business interactions. hence, l2 learners of business english should be exposed to these devices through cohesion-...

Desert ecosystems are an environment of climatic extremes, to which many forms life have adapted. These systems characterized by scarce water and often sparsely vegetated lands where ecological adaptation arid conditions has its underpinnings in the universal dependency on support life. Understanding ecohydrological similarity springs water-limited areas requires integration multiple lines evid...

The effect of monochloro and dichloro substitution into the ethyl portion on the pyrolysis of ethyl vinyl ether has been studied. This involved four possible monosubstituted derivatives and six disubstituted derivatives. For the monochloro derivatives, B- chloro substitution enhanced the rate constant while a- chloro substitution depressed it noticeably. For the dichloro derivatives, substi...

some substitution lines between two parental lines for complex traits allows for the identification of single Genetic analyses of complex traits in wheat (Triticum aestivum L.) chromosomes containing QTLs for those traits (Berke are facilitated by the availability of unique genetic tools such as chroet al., 1992a,b; Cantrell and Joppa, 1991). Single recipromosome substitution lines and recombin...

Synthesis of the CuSr2YCu20 7 compounds with Re, W and Mo substituted for Cu has been optimized for the highest T~. Materials prepared in air at 990°C and annealed at 650-700°C in 220 atm. 02 are tetragonal with the transition elements substituting on the Cu-"chain" site, have oxygen content ~ 7.3, and are superconducting with T~ ~ 70 K. The irreversibility lines show rather poor pinning charac...
