background: sperm preparation is a fundamental step in art and attempt for developing new methods to be continued. objective: to evaluate the efficacy of upstream method for separation of human spermatozoa and its effects on sperm parameters including: motility morphology and concentration. materials and methods: semen samples from 17 men who referred to infertility clinic for evaluating their ...

The dramatic increasing of sea-freight container transportations and the developing trend for using containers in the multimodal handling systems through the sea, rail, road and land in the present market cause some challenges to the general managers of container terminals such as increasing demand, competitive situation, new investments and expansion of new activities and the need to use new m...

Increased customer demands have taken substantial effect on the formation of strategies for container terminal operations and in turn became important for performance evaluation of container terminals. This s...

This paper addresses the applications of different techniques for solving container terminals problems. We have built a simulation model that can be used to analyze the performance of container terminal operations. The proposed approach is intended to be applied for a real case study in Alexandria Container Terminal (ACT) at Alexandria port. The implementation of our approach shows that a propo...

In this paper efficient in time methods for support decision-making processes in small container terminal operated by reachstackers are proposed. Two main problems are considered: first, minimization the number of loading/unloading operations between container trains and bays, second, minimization the number of re-handing operations within container bays. in Gliwice, Poland to model the problem...

Since the last two decades, container transportation system has been faced under increasing development. This fact shows the importance of container transportation system as a key role of container terminals to link between sea and land. Therefore, there is a continuous need for the optimal use of equipment and facilities in the ports. Regarding the complex structure of container ports, this pa...

An overview of literature is conducted on research focusing on improving the performance of container terminals. The growth of containerization has led to numerous decision problems for container terminal management to consider in operating their container terminals more efficiently, e.g. where to place a ship along a quay, scheduling the resources to work a ship, etc. The research papers revie...

Let k ≥ 3 be a fixed integer and let Zk(G) be the number of k-colourings of the graph G. For certain values of the average degree, the random variable Zk(G(n,m)) is known to be concentrated in the sense that 1 n (lnZk(G(n,m)) − lnE[Zk(G(n,m))]) converges to 0 in probability [Achlioptas and Coja-Oghlan: Proc. FOCS 2008]. In the present paper we prove a significantly stronger concentration result...
