Semi-Analytic Third-Order Purely Secular J - S Planetary Theory
ISBN: 9786204714233 / Angielski / Miękka / 100 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. The variation of the orbital planetary elements is the subject of general perturbations. We suppress the Hamiltonian approach. The readers of the book should be the graduate students of Applied Mathematics and Dynamical Astronomy as well as interested readers in this subject. We offer complete symbolic computations for a second-order J - S theory. We assume the J - S couple to be as point masses. We used the Macsyma programs to determine the expansion of, up to degree 6 in eccentricity - inclination, since the PC cannot pass this upper limit for a third-order J - S theory.

Diversity and distribution of water plants in the Nile Delta of Egypt
ISBN: 9783659623905 / Angielski / Miękka / 2014 / 216 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. The Nile Delta comprises about 63% of Egypt's most fertile land. The present flora and vegetation of water plants growing in water channels of the Nile Delta were studied through four main sectors covering its whole area. Distribution maps of some species were presented in different categories of species distribution. The severe human activities contributed largely in the disappearance of many hydrophytes. The numerical analysis of the vegetation revealed the identification of 17 vegetation groups in the different sectors. The relationship between water and its macrophytic vegetation was...
