Distribution centers are one of the most important components in a supply chain. In the context of a new global economy in which filling orders within a 24-hour period is the industry standard, product locating, replenishing and picking activities must be managed efficiently. This article proposes and analyzes different product location and replenishment strategies for a distribution center tha...

The microbiological monitoring of the water used for hemodialysis is extremely important, especially because of the debilitated immune system of patients suffering from chronic renal insufficiency. To investigate the occurrence and species diversity of bacteria in waters, water samples were collected monthly from a hemodialysis center in upstate São Paulo and tap water samples at the terminal s...

INTRODUCTION Glomerulonephritis is the third most common cause of end-stage renal disease. Epidemiological data of kidney disease is population-based and has great geographic variability. The aim of this study was to assess the results of all kidney biopsies in a 5-year period in the Guilan province. MATERIALS AND METHODS In a retrospective study of 336 kidney biopsies recorded in the Departm...

Due to climate change, frequencies of natural disasters, including earthquake, hurricane, typhoon and heavy precipitations, increase rapidly. The emergency distribution center (EDC) plays an important role in emergency planning and disaster response. During the process of delivering relief to shelters, the infrastructure could be deteriorated by the disaster. Most of the existing models neglect...

Rapid increasing logistics demands call for high efficiency delivery in cities. Effective city planning of distribution centers is crucial. This paper first analyzes the current situation and constraint of Shanghai distribution centers. Then investment proposal is made for Shanghai distribution center relocation. The facility site selection and layout plan are proposed, and the commitment is ca...

Quantum correlation between two particles and among three particles show nonclassic properties that can be used for providing secure transmission of information. In this paper, we propose two quantum key distribution schemes for quantum cryptographic network, which use the correlation properties of two and three particles. One is implemented by the Greenberger-Horne-Zeilinger state, and another...
