Egyptian Oases are still the most varied in the world, each one has a special character.Siwa Oasis is a place of magic and quietness with a unique ecology.This research tends to show the problems associated with the traditional construction technique in Siwa oasis due to the weakness of the available building materials such as Karshif particles and
Only very few cases have documented that an increase in connectivity after a period of fragmentation in ecological time has had an effect on the distribution, genetic structure and morphology of stenotopic species.In this study we present an example of clinal variability in a woodland ground Wooden Blocks beetle as a result of changes in the connec
CD44 is a multifunctional adhesion molecule typically upregulated in malignant, inflamed and injured tissues.Due to its ability to bind multiple ligands present in the tumor microenvironment, it promotes multiple cellular functions related to tumorigenesis.Recent data has shown that CD44 and its principal ligand hyaluronan (HA) are carried by extra
In this paper, we look into the Wooden Stacking dynamic motion planning and control of an unmanned aerial vehicle, namely, the quadrotor, governed by its dynamical equations.It is shown for the first time that the Direct or the Second Method of Lyapunov is an effective tool to derive a set of continuous nonlinear control laws that not only provide
