if we study the contemporary palestinian poetry of the last century we will find that the theme of nationhood and motherland dominates it. one reason is the fact that during this period palestine has been through such events that has ignited a sense of patriotism, a wish to defend of the motherland and the arabic origin of the palestinian people. since the balfour declaration, the endeavour to ...

It seems like in the contemporary era and with the use of approaches which are formed during a passage from structuralism to poststructuralism, a number of fundamental changes have taken place in the different types of relationships between the works of architecture, their methods of productions and different readings of it along with the differences in the types of research and criticism among...

Drosophila, Wnt, FGF, Jak/Stat, Rho, Rac, RhoGEF, Pebble, Naked Cuticle The site for the latest installment of the Fly Meeting (March 7–11) was downtown Philadelphia. The conference offered an illustration of all that is great about the Drosophila field bringing together evolutionary biologists, immunologists and everyone in between. Here I will provide a small sample of several advances from t...

We show that the oscillatory driving of crystal surfaces can induce pattern formation or smoothening. Depending on driving conditions, step bunching and meandering, mound formation, or surface smoothening may be seen in the presence of a kinetic asymmetry at the steps or kinks. We employ a step model to calculate the induced mass flux along misoriented surfaces, which accounts for surface dynam...

PURPOSE OF REVIEW Nausea and vomiting of pregnancy (NVP) affects 90% of pregnant women and its impact is often underappreciated. Hyperemesis gravidarum, the most severe end of the spectrum, affects 0.5-2% of pregnancies. The pathogenesis of this condition remains obscure and its management has largely been empirical. This review aims to provide an update on advances in pregnancy hyperemesis foc...

We study the control of modulational instability and pattern formation in a nonlinear dissipative feedback system with a periodic modulation of the material refractive index. We use a one-dimensional photonic lattice in a single-mirror feedback configuration and identify three mechanisms for pattern control: bandgap suppression of instability modes, periodicity induced pattern modes, and orient...

We present some numerical results obtained from a simple individual-based model that describes clustering of organisms caused by competition. Our aim is to show that, even when a deterministic description developed for continuum models predicts no pattern formation, an individual-based model displays well-defined patterns, as a consequence of fluctuation effects caused by the discrete nature of...
