Abstract Most people who use the word ‘Latin’ as name of a language in antiquity (not Medieval or Neo-Latin therefore) seem unaware that Latin was continuum made up many different varieties, Classical (which they identify with Latin) being only one them. So when talk spoken mean Latin, no other variety from available is suitable to be spoken. This ironic on two counts. First, overwhelming major...

Effective radius re (defined as the ratio of the third to the second moment of a droplet size distribution) is one of the crucial variables that determine the radiative properties of liquid water clouds (Hansen and Travis 1974). The inclusion and parameterization of re in climate models has proven to be critical for assessing global climate change (Slingo 1990; Dandin et al. 1997). There has be...
The online tool travis can synthesize a k-bounded Petri net model from a reachability graph and unfold a k-bounded Petri net to its reachability graph. Synthesis is built on the theory of regions, but where travis and other existing tools only show the synthesized model, we want to present the synthesized model as well as the calculated regions after a user has performed the synthesis procedure...

پیش زمینه : توبرکلوزیس از طریق عفونت با مایکوباکتریوم توبرکلوزیس ایجاد می شود .امروزه یکی از بزرگترین مشکلات مسائل بهداشت جهانی بیماری سل می باشد. فاکتورهای مستعد کننده افراد به یک عفونت جدید یا عود کردن عفونت ناشناخته است. فاکتورهای میزبان، به طور اختصاصی ژن های میزبان، در حساسیت و شدت عفونت و همچنین در سلامت حاصل برای بیمار موثرند. پلی مورفیسم های سیتوکین می توانند در فعالیت پاسخ ایمنی به عف...
The CI and CI-like chondrites provide a record of aqueous alteration in the early solar system. However, the CI-like chondrites differ in having also experienced a late stage period of thermal metamorphism. In order to constrain the nature and extent of the aqueous and thermal alteration, we have investigated the bulk mineralogy and abundance of H2O in the CI and CI-like chondrites using thermo...
