Dasythemis Karsch, 1889 One of the four species of this genus occurs in Ecuador (Fig. 89). See Ris (1910) for identification. Adults are slight of stature; they perch near partly shaded ponds and swamps. Dasythemis esmeralda Ris, 1910. Publ. Recs. ECU: Campos (1925), F...

The use of impact attenuators (IA) is important for vehicles as they absorb the kinetic energy exerted from the car crashes to protect the drivers from any possible injuries. Under the framework of the Formula Student (FS) competition, we investigate various designs of ...

a b s t r a c t Several multi-year biodiversity experiments have shown positive species richness-productivity rela- tionships which strengthen over time, but the mechanisms which control productivity are not well understood. We used experimental grasslands (Jena Experim...

The synthesis of 14-aryl 14H-dibenzo[a,j]xanthenes is achieved by a simple condensation reaction between β-naphthol with aryl or alkyl aldehydes in an effective synergetic catalytic system created by combining basic bleaching earth clay and PEG-600. The advantages of th...

A partir dos anos 70 e 80 do seculo passado, o advento dos estudos clinicos aleatorizados e de grandes coortes, associado ao desenvolvimento da metodologia para realizacao de revisoes sistematicas e metanalises, provocou uma revolucao na forma de pensar e realizar a pra...

The Thermus thermophilus gene encoding the preprotein translocation ATPase SecA was cloned and expressed and the purified protein was crystallized by the hanging-drop vapour-diffusion technique in two different space groups P31(2)21 (a = b = 168.6, c = 149.8 A) and P61(...

We call a positive real number $\lambda$ admissible if it belongs to the Lagrange spectrum and there exists an irrational number $\alpha$ such that $\mu(\alpha)=\lambda$. Here $\mu(\alpha)$ denotes the Lagrange constant of $\alpha$ - maximal real number $c$ such that $\...
