Consider a planar Brownian motion run for nite time. The frontier or \outer boundary" of the path is the boundary of the unbounded component of the complement. Burdzy (1989) showed that the frontier has innnite length. We improve this by showing that the Hausdorr dimension of the frontier is strictly greater than 1. (It has been conjectured that the Brownian frontier has dimension 4=3, but this...

Object oriented design patterns as popularized in [GHJV95] are intended to solve common programming problems and to assist the programmer in designing and developing robust systems. As first year courses increasingly emphasize object orientation, knowledge of design patterns and when to use them becomes an important component of the first year curriculum. Recent literature has focused on introd...

In this paper we would like to present our application for editing and visualizing huge point clouds. We also show how we used our application to build a model of the Domitilla Catacomb in Rome, which is the largest catacomb in Rome. It is an Early-Christian necropolis spanning 15 km of subterranean galleries. The catacomb contains tombs and community burials, where some of the tombs are painte...

Although the renin angiotensin system (RAS) is a well established regulator of blood pressure and intravascular volume,1 considerable evidence has emerged demonstrating the importance of the RAS directly on the cardiovascular system (please refer to the Figure for description of the enzymatic pathways involved in RAS regulation). Indeed, angiotensin converting enzyme (ACE) inhibitors, which pre...

Oxidative stress, defined as an increase in reactive oxygen species, has been implicated in a number of diseases, including hypertension. Superoxide is a particularly detrimental reactive oxygen species in the cardiovascular system because it reacts directly with NO, thereby limiting the amount of NO normally available for processes such as endothelium-dependent relaxation. Superoxide dismutase...

Water stress effects on winter and spring leaves anatomy were investigated in experiments conducted at the experimental field of SB University of Kerman using five wheat cultivars.Xylem and phloem elements diameter and mesophyll, bundle sheath and epidermal cells area were measured in transverse sections prepared from middle parts of the leaves. Results showed that significant difference exists...
