Background: Several studies have investigated the variations in the anatomy of each segment of circle of Willis whereas a few have addressed the variations of this arterial circle as a whole. In this study the entire circle of Willis and its variations were studied in a cohort of Iranian people and compared with previous reports.Methods: Anatomical variations of the circle of Willis in 132 brai...
"Development" and "modernization" or "modernity" are related concepts that are widely but variously used to refer to major social, economic and political changes. Some scholars equate political development with the ability of a political system to grow and adjust to new demands put upon it. The environment of bureaucracy may be visualized as series of concentric circles, with bureaucracy at th...
ardy and littlewood conjectured that every large integer $n$ that is not a square is the sum of a prime and a square. they believed that the number $mathcal{r}(n)$ of such representations for $n = p+m^2$ is asymptotically given by begin{equation*} mathcal{r}(n) sim frac{sqrt{n}}{log n}prod_{p=3}^{infty}left(1-frac{1}{p-1}left(frac{n}{p}right)right), end{equation*} where $p$ is a prime, $m$ is a...
Kaaba known as Qibla and the focus point of Muslim people is of paramount importance. Many scientists in the field of mathematics, astronomy and geography throughout the Islamic world tried to find the exact methods and procedures to determine the direction of Qibla. One of these methods is Hindi Circle used to determine Qibla of mosques. Most often the scientists, scholars and astronomers gath...
We deene Picard-Einstein metrics on complex algebraic surfaces as KK ahler-Einstein metrics with negative constant sectional curvature pushed down from the unit ball via Picard modular groups allowing degenerations along cycles. We demonstrate how the tool of orbital heights, especially the Proportionality Theorem presented in H98], works for detecting such orbital cycles on the projective plan...
