Proposing a Function for Char-Ghapi, Qasr-e-Shirin, Iran: Historical and Archaeological Evaluation

Qasr-e Shirin owes its prominence primarily to the Sassanian period and the attention the region received from Khosrow Parviz. Khosrow took the first steps to make Qasr-e-Shirin habitable by constructing a complex consisting of a palace, a fortress, a religious building, a defensive wall and a water conveyance system. Later, Qasr-e-Shirin is mentioned in several texts and travel itineraries. Th...

Calcimimetic R-568 and Its Enantiomer S-568 Increase Nitric Oxide Release in Human Endothelial Cells

BACKGROUND Calcimimetics, such as R-568, are thought to activate G protein-linked Ca(2+)-sensing receptor (CaSR) by allosterically increasing the affinity of the receptor for Ca(2+) allowing for efficient control of uremic hyperparathyroidism. Several recent studies suggest they possess additional vascular actions. Although it has been postulated that calcimimetics may have a direct effect on C...

The Basic Theorem and its Consequences

Let T be a compact Hausdorff topological space and let M denote an n–dimensional subspace of the space C(T ), the space of real–valued continuous functions on T and let the space be equipped with the uniform norm. Zukhovitskii [7] attributes the Basic Theorem to E.Ya.Remez and gives a proof by duality. He also gives a proof due to Shnirel’man, which uses Helly’s Theorem, now the paper obtains a...
