Dear Editor, Nocardia species are uncommon pathogens that affect immunosuppressed patients; although cerebral nocardiosis is a rare condition, it is associated with significant morbidity and mortality [1]. Because Nocardia species exhibit different antibiotic susceptibilities, accurate species identification is important for prognoses. To the best of our knowledge, this is the first case of Noc...

Countries differ markedly in the diversification of their exports. Products differ in the number of countries that export them, which we define as their ubiquity. We document a new stylized fact in the global pattern of exports: there is a systematic relationship between the diversification of a country’s exports and the ubiquity of its products. We argue that this fact is not implied by curren...

E xchange rate is an important factor influencing price indices of exported goods of a country in different ways. Imported intermediate commodity is one of the important ways by which the change in exchange rate affects price indices of the exported goods. Using the input-output table of Iran for the year 2001, this paper investigates the impact of exchange rate devaluation on price ...

Direct and indirect effects of microorganisms on technetium insolubilization in water covering waterlogged soils were studied. Seven soils were waterlogged and then the water covering the soils were collected for further tracer experiments. The samples in contact with air were incubated with TcO4 at 25 ̊C for 4 to 5 days. After incubation, the samples were sequentially separated into four fracti...

The presence of somatic B-catenin mutations in some prostate cancers implies that aberrant WNT signaling is involved in the cancer development. Although B-catenin stability is regulated by a multicomponent destruction complex, mutational alterations of B-catenin or other components of the destruction complexes are rare in prostate tumors. Therefore, B-catenin may be regulated by another protein...

This paper focuses on the factors which influence collaborative learning in distance education. Distance education has been around for many years and the use of collaborative learning techniques in distance education is becoming increasingly popular. Several studies have demonstrated the superiority of collaborative learning over traditional modes of learning and it has been identified as a pot...
