Numerous factors influence cell functions and tissue development in culture. A modular culture system has been developed to allow the control of many of these important environmental parameters. Optimal adhesion of cells is obtained by selecting an individual biomaterial. Selected specimens are mounted in a tissue carrier in order to protect it against damage during handling and after seeding c...

The current financial crisis seems to be seriously affecting the freight transport system. In this scenario, transport terminals play a crucial role to avert the risk of recession by increasing their efficiency and automation. Only in this way is it possible both to reduce the price of the services offered (loading, unloading, dwelling, logistic services ...) and increase terminal earnings. In ...

In this paper, the skew control of the load (container) in the quay crane used in the dockside of a container terminal is investigated. The mathematical model of the 3-dimensional (3D) motions of the load is first derived. The container hooked to a spreader is suspended by four ropes in air. When the container is accelerated by the trolley or is disturbed by winds, it will make a rotational mot...

Container terminals world wide are trying to expand capacity and increase performance at a minimum of investments. Often the container terminal operations are changing to meet increased customer demands as well as to adapt to new technologies. The increasing costs of container terminal development do justify the use of computer simulation to assist in planning and policy making. A flexible simu...

Experimental studies on animal models play essential roles in the development of preventive, diagnostic and therapeutic procedures for diseases in a wide spectrum of fields including neurological sciences. The goal of this study was to demonstrate the shell-less culture system of the chick embryo as a potential experimental model in the field of developmental neurobiology. We were able to obser...

Due to rapid growth in foreign trade using sea vessels, there is a growing focus in improving the infrastructure and operational efficiencies at the container terminals. Particularly, the operational responsiveness of loading and unloading of containers, affects the vessel idle times and profitability of the shipping liners. In this research, we determine optimal stack layout design, which mini...

A k-container C(u, v) of a graph G is a set of kdisjoint paths joining u to v. A k-container C(u, v) of G is k∗-container if C(u, v) spans G. A graph G is k∗-connected if there exists a k∗-container between any two distinct vertices. Let κ(G) be the connectivity of G. In this paper, we prove that the n-dimensional burnt pancake graph Bn is n∗connected for any positive integer n.

A k-container C(u, v) of G between u and v is a set of k internally disjoint paths between u and v. A k-container C(u, v) of G is a k∗-container if it contains all vertices of G. A graph G is k∗connected if there exists a k∗-container between any two distinct vertices. In this paper, we prove that the n-dimensional fully connected cubic network FCCNn is 3 ∗-connected for n ≥ 2.

We present three diierent methods for nding solutions to the 2D translation-only containment problem: nd translations for k polygons that place them inside a given polygonal container without overlap. Both the container and the polygons to be placed in it may be nonconvex. First, we provide several exact algorithms that improve results for k = 2 or k = 3. In particular, we give an algorithm for...

We propose a new index, the Container Port Connectivity Index (CPCI), to measure the trade connectivity of ports within the network of container shipping. This index is based on both economics and network topology, and a distinctive feature is that the strength of a port is based on its position within the global structure of the shipping network and not just on local information such as the nu...
