استفاده از گیاهان دارویی قدمتی همپای بشر داشته و طی سالیان متمادی داروهای طبیعی خصوصا گیاهان دارویی اساس و حتی در برخی موارد تنها طریق درمان محسوب می شدند و در عین حال مواد اولیه موجود در آن ها در صنعت داروسازی مورد استفاده قرار می گرفت. در اوایل قرن حاضر پیشرفت علم شیمی و کشف سیستم های سنتز آلی منجر به توسعه صنعت داروسازی و جایگزینی شیمی درمانی شد. تمایل به تولید گیاهان دارویی و معطر و تقاضا ب...

Scyphomedusae undergo a predictable ontogenetic transition from a conserved, universal larval form to a diverse array of adult morphologies. This transition entails a change in bell morphology from a highly discontinuous ephyral form, with deep clefts separating eight discrete lappets, to a continuous solid umbrella-like adult form. We used a combination of kinematic, modeling, and flow visuali...

Et Tu, Torsten? This critique of my Economic Policy paper generates many emotions. It is certainly an honor for my research to be taken seriously by such an eminent scholar as my friend Torsten Persson. And while any publicity is good, a negative citation dominates a positive one. There is irony; I came up with the original idea in a hallway conversation with Harry Flam a few feet from Persson...
A traditional view of the nature of species holds that populations within species maintain genetic cohesion through substantial intraspecific gene flow and that the whole genome of a species is protected from interspecific gene flow by strong reproductive isolation. Both aspects of this view have been challenged. Reproductive barriers between recently evolved species can be incomplete and perme...
This paper describes and discusses the impacts of the passage of cold fronts on the vertical structure of the Carlos Botelho (Lobo-Broa) Reservoir as demonstrated by changes in physical, chemical, and biological variables. The data were obtained with a continuous system measuring 9 variables in vertical profiles in the deepest point of the reservoir (12 m) coupled with climatological informatio...
Two new species of Dolichothele Mello-Leitão, 1923 are described from Brazil and Bolivia, D. mottaisp. n. from Distrito Federal and the state of Goiás, Brazil, and D. camargorumsp. n. from the state of Rondônia, Brazil, and the La Paz region, Bolivia. Males of the two new species resemble Dolichothele bolivianum (Vol, 2001) in having a small subapical keel on the distal embolus and females in p...
The emerald ash borer (EAB), Agrilus planipennis Fairmaire (Col., Buprestidae), an invasive pest currently threatening the complete destruction of North America’s ash resource, was first detected in the Midwestern United States and adjacent Canada in 2002 (Haack et al. 2002). Effective detection and monitoring of this pest has so far remained elusive (Poland and McCullough 2006). Identifying a ...
Nanocrystals of group II-VI semiconductors, known as quantum dots (QDs), in which electrons and holes are three dimensionally confined within the exciton Bohr radius of the material, are characterized by the exceptional optical properties, such as broad absorption and sharp emission bands as well as size-tunable photoluminescence in the visible spectral range. The most popular are CdSe/ZnS QDs ...
