Seventy-five years ago, Walter Benjamin showed us that the line between "production" and "reproduction" had begun to blur. Reproduction was no longer optional, consequential and degrading (the shredding of the original’s aura), but was instead being transformed into a principle…

Enantiomerically enriched cyanohydrin O-phosphates, prepared
by enantioselective cyanophosphorylation of α,β-unsaturated
aldehydes, react regioselectively at the γ-position
with organocuprates derived from alkyl Grignard reagents
and CuCN to afford chiral γ-alkyl-substituted α,β-unsaturated
nitriles. The configuration of the new C–C double bond
is…

A new analytical approximate expression for the period of the simple pendulum is obtained by using a heuristic but pedagogical derivation. This formula depends on two parameters obtained by comparing term-by-term the power-series expansions of the approximate and exact expressions…

The synthesis of a GSK 2nd generation inhibitor of the hepatitis C virus, by enantioselective 1,3-dipolar cycloaddition between a leucine derived iminoester and tert-butyl acrylate, was studied. The comparison between silver(I) and gold(I) catalysts in this reaction was established by…

The analytical approximate technique developed by Wu et al. for conservative oscillators with odd nonlinearity is used to construct approximate frequency-amplitude relations and periodic solutions to the relativistic oscillator. By combining Newton's method with the method of harmonic balance, analytical…

Litigation is now a common occurrence and the sport environment is not excluded. The law affects all aspects of sport, whether you are an Olympic champion, a referee of a soccer game, a fan of special team, a constructor or…

Christian athletes are people with specific and distinctive moral guidelines in everyday life as well as in competitive sports. No matter if they are competing in triathlon, athletics, or playing soccer, if they are playing in the lowest or highest…

Taekwondo is a combat sport emphasizing on kicking techniques and dynamic footwork. Specialized balance ability is crucial for Taekwondo practitioners. This study aimed to compare (1) the postural stability during turning, and (2) the forward lunge distance between adolescent TKD…
