the aim of this study is to propose a new mixed integer linear programming (milp) model to find the minimum required number of yard cranes, rubber tyred gantry cranes (rtgcs), for completion the total amount of works at the end of planning horizon. in other word, we find the optimal number of yard cranes in a container terminal which completes the total amount of works. the paper supports the p...

The labour requirements and capital costs for the various cane yard layouts in the South African mills vary significantly. The various types of equipment available for cane handling and their effect on the capital and operating costs of the cane yard are discussed.

Management of container terminal operations is essentially the allocation and scheduling of the expensive resources such as berths, quay cranes, storage space, yard cranes, and container carriers. Each of these resources plays an indispensable role in the interlocking processes in a container terminal. In this survey we give a critical review and a comparative study on various decision problems...

Keywords: Container terminal Maritime shipping Block length Yard crane deployment Simulation Terminal design Gross crane rate As more and more container terminals open up all over the world, terminal operators are discovering that they must increase quay crane work rates in order to remain competitive. In this paper we present a simulation study that shows how a terminal's long-run average quay...

BACKGROUND Improving knowledge on local determinants of visceral leishmaniasis (VL) is crucial to guide the development of relevant control strategies. This study aimed to identify individual and household level determinants of primary VL in 24 highly endemic villages of Tabarak Allah hospital's catchment area, Gedaref State, Sudan. METHODS From September 2012 to July 2013, in an unmatched ca...

Hypocretin (Hcrt) has been implicated in the control of motor activity and in respiration and cardiovascular changes. Loss of Hcrt in narcolepsy is linked to sleepiness and to cataplexy, a sudden loss of muscle tone which is triggered by sudden strong emotions. In the current study we have compared the effects of treadmill running, to yard play on cerebrospinal fluid (CSF) Hcrt level in normal ...
