Ordered porous materials with unique pore structures and pore sizes in the mesoporous range (2-50 nm) have many applications in catalysis, separation and drug delivery. Extensive research has resulted in mesoporous materials with one-dimensional, cage-like and bi-continuous pore structures. Three families of bi-continuous mesoporous materials have been made, with two interwoven but unconnected ...

The creative synthesis invented by Ibn Sīnā requires a particular view of the relation between religion and philosophy in such a manner ...

The classic model of saccade generation assumes that the burst generator is driven by a motor-error signal, the difference between the actual eye position and the final "desired" eye position in the orbit. Here we evaluate objectively, using system identification techniques, the dynamic relationship between motor-error signals and primate inhibitory burst neuron (IBN) discharges (upstream analy...

yüzyılda başlayan özellikle de XII. yüzyılın ilk çeyreğinde hızlanan Arapçadan İbraniceye tercüme süreci XVI. sonlarına kadar devam etmiştir. Bu süreçte Fârâbî, İbn Sînâ, Gazzâlî ve Rüşd gibi önde gelen Müslüman filozofların felsefe teolojiye dair eserleri doğrudan ya da aracı diller üzerinden edilmiştir. sürecinde Arapça bilen Yahudi düşünür mütercimler bir yandan farklı alanlardan seçtikleri ...
