In this paper, we introduce a unified fractional derivative, defined by two parameters (order and asymmetry). From this, all the interesting derivatives can be obtained. We study one-sided show that most known are particular cases. consider also some myths of Fractional Calculus false derivatives. The results expected to contribute limit appearance differ from existing ones just because they on...

There is growing evidence that there are more—perhaps many more. The idea that there are four basic tastes goes back at least as far as ancient Greece, so if there are more than four basic tastes why haven't t...

'How many species are there' is a question receiving more attention from biologists and reasons for this are suggested. Different methods of answering this question are examined and include: counting all species; extrapolations from known faunas and regions; extrapolations from samples; methods using ecological models; censusing taxonomists' views. Most of these methods indicate that global tot...
