evaluation of autogenous fibrinogen extracted from horse blood in fibrin glue and it's effects on horse's fibroblast and keratinocyte cells were preformed. fibrinogen has been obtained by glycine precipitation technique from horse's blood. fibroblast cells were separated by explant culture method from neck skin and keratinocytes were separated by enzyme digestion from lib samples...

Let S be a d-dimensional separoid of (k− 1)(d+1)+1 convex sets in some ‘large-dimensional’ Euclidean space IE . We prove a theorem that can be interpreted as follows: if the separoid S can be mapped with a monomorphism to a d-dimensional separoid of points P in general position, then there exists a k-colouring ς:S → Kk such that, for each pair of colours i, j ∈ Kk, the convex hulls of their pre...

W e present an optimal parallel algorithm t o construct the well-separated pair decomposition of a point set P in Zd. W e show how this leads to a deterministic opt imal O(1ogn) t ime parallel algorithm for finding the k nearest neighbors of each point in P, where k is a constant. W e discuss several additional applications of the well-separated pair decomposition for which we can derive fas t ...

the separation of saffron stigmas from fresh flowers is the most important and the most difficult stage of saffron harvesting. saffron production costs are high because this harvesting stage is done by hand and is very time-consuming. one way of preserving the saffron flower is to dry it. the separating of the stigma from dried saffron flowers can then be done at an appropriate time. this study...

In this study, s-triazine rings (or their derivatives) were introduced into a two-dimensional phase-separated mixed monolayer of hydrocarbon-fluorocarbon chains. The diamino-triazine ring facilitated the absorption deoxyribonucleic acid (DNA) molecules in monolayer. diamino ring-containing copolymers which hydrogenated hydrophobic chain was able to form mixed-phase-separated monolayers when com...

A Franson-type test of the Bell-inequality is presented. Energy and time entangled photons at wavelengths of 704 and 1310 nm are produced by para-metric downconversion in KNbO3 and are sent through optical fibers into a bulk-optical (704 nm) and a fiber-interferometer (1310 nm), respectively. The two interferometers are located 35 meters aside from one another. Using Faraday-mirrors in the fibe...

Given a geometric graph G = (S,E) in R with constant dilation t, and a positive constant ε, we show how to construct a (1 + ε)-spanner of G with O(|S|) edges using O(sort(|E|)) memory transfers in the cacheoblivious model of computation. The main building block of our algorithm, and of independent interest in itself, is a new cache-oblivious algorithm for constructing a well-separated pair deco...

The fast multipole method (FMM) performs fast approximate kernel summation to a specified tolerance ǫ by using a hierarchical division of the domain, which groups source and receiver points into regions that satisfy local separation and the well-separated pair decomposition properties. While square tilings and quadtrees are commonly used in 2D, we investigate alternative tilings and associated ...
