UNLABELLED BACKGROUND Emergency departments (EDs) are the basic units of emergency care. We performed a national inventory of all Singapore EDs and describe their characteristics and capabilities. METHODS Singapore EDs accessible to the general public 24/7 were surveyed using the National ED Inventories instrument ( http://www.emnet-nedi.org). ED staff members were asked about ED cha...

We consider a variant of the periodic review system with a virtual warehouse that is due to Eppen and Schrage (1981). Depending on the realized pattern of demand during the delivery leadtime, this inventory is dynamically allocated or rationed to each of the retailers. While Eppen and Schrage (1981) assume that all unfilled demand is backordered, we allow some demand to be rejected to keep inve...

The Lower Fungom region of Northwest Cameroon is one of the most linguistically diverse areas of the Cameroonian Grassfields. Seven languages, or small language clusters, are spoken in its thirteen recognized villages, four of which are restricted to a single village. While the languages are all recognizably Bantoid, five of them do not have any established close relatives outside of the region...

This article presents theoretical basis of spare parts inventory management in manufacturing company. Basis definitions, allocation and differences in spare parts inventory management were compared with other manufacturing inventories. The issue of spare parts inventory management is emphasized in aspect of maintaining continuity of production and generated costs of maintaining inventory.

The LEGO Group has become the largest toy company in the world and they can look back to a proud history of more than 50 years of producing bricks and other toys. Starting with a simple set of basic bricks their range of toys appeared to have increased in complexity over the years. We processed the inventories of most sets from 1955-2015 and our analysis showed that LEGO sets have become bigger...

The study of fish concentrations and sediment inventories in 19 European high mountain lakes (40-67 degrees N) shows that a fraction of organochlorine compounds (OCs), the less volatile compounds (LVC; subcooled liquid vapor pressure < or = 10(-2.5) Pa), are trapped in the higher locations. This general trend is not significantly influenced by possible local sources. Compound distribution is re...

Identifying the functionally distinct types of neuron is central to any bottom-up understanding of how the brain works. The different cell types are the brain’s elementary computational elements — the components from which the larger machine is made. We have known of some cell types for more than a century, but the coverage has been spotty and anecdotal. This is changing: it is now possible to ...
