In complex task domains, such as games, students may exceed their teachers. Such tasks afford diverse means to tradeoff one type of performance for another, combining task elements in novel ways to yield method variations and strategy discoveries that, if mastered, might produce large or small leaps in performance. For the researcher interested in the development of extreme expertise in the wil...

Protein Description 393 amino acids; 53 kDa phosphoprotein; contains, from N-term to C-term, a transactivation domain, a DNA-binding domain, nuclear localization signals and a tetramerization domain. Expression Widely expressed. Localisation Nucleus. Function Tumour suppressor gene; P53 is a transcriptional regulator acting as a guardian of the genome; in response to DNA damage, p53 is overexpr...

We consider an ideal gas of massive hadrons in thermal and chemical equilibrium. The gas expands longitudinally in an adiabatic way. This evolution for a baryonless gas reduces to a hydrodynamic expansion. Cooling process is parametrized by the sound velocity. The sound velocity is temperature dependent and is strongly influenced by hadron mass spectrum. ∗Work partially supported by the Polish ...

Salicylic acid (SA) is an endogenous plant growth regulator, acting as non enzymatic antioxidant and has a regulatory effect on some physiological and biochemical processes. Therefore, this work was conducted during two successive summer seasons to evaluate the performance of two sunflower cultivars (Sakha 53 and Giza 102) to salicylic acid. The plants were grown at the experimental station of ...
