a growing body of research has indicated that students of esl/efl are reticent and unwilling to be engaged in oral activities in english lessons. communicative language ability includes speaking ability, so vocabulary knowledge plays an integral role in speaking a language. however, there have been few studies examining the degree to which vocabulary knowledge affects speaking ability. the pres...

this experiment was carried out at the college of agriculture university of salahaddin erbil. to study the effect of water supplementation with propolis on local quail performance, some physiological and immunological characteristics at 42 days old. a total of one thousand fifty (1050) hatched local quail eggs that obtained from the project of al-rashedia for agriculture researches center in mo...

Interstitial pneumonia is a frequent and critical manifestation of human cytomegalovirus (CMV) disease in immunocompromised patients, in particular in recipients of bone marrow transplantation. Previous work in the murine CMV infection model has identified the lungs as a major organ site of CMV latency and recurrence. It was open to question whether the viral genome is transcriptionally silent ...

Trends in conventional plant breeding and in biotechnology research are analyzed with a focus on production and productivity of individual organisms. Our growing understanding of the productive/adaptive potential of (crop) plants is a prerequisite to increasing this potential and also its expression under environmental constraints. This review concentrates on growth rate, ribosome activity, and...

The state of cytomegalovirus (CMV) after the resolution of acute infection is an unsolved problem in CMV research. While the term "latency" is in general use to indicate the maintenance of the viral genome, a formal exclusion of low-level persistent productive infection depends on the sensitivity of the assay for detecting infectious virus. We have improved the method for detecting infectivity ...
