A multi-stage Kanban based production system (MKPS) with variable production rates is considered. This paper is to study and analyse the process of designing an effective flexible Kanban pull system and to design and develop a method for MKPS with varying production rate at different work-stage. Raw materials are replenished at the first work-stage and they are processed through MKPS to generat...

This article focus on the behaviour of a multi-product batch production line with fixed capacity which is scheduled according to inaccurate inventories (IRI). We assume an unlimited supply of raw materials and a constant demand for the different finished goods. The ordering policy of this production line is based on a (Q,R) continuous review, lost-sales inventory model and on given priority for...

Safe handling of chemotherapeutic agents during administration and disposal is critical. Most antineoplastic agents are toxic compounds that are carcinogenic, mutagenic, or teratogenic. Direct contact may cause irritation of the skin, eyes, and mucous membranes. Perioperative personnel should know how to handle hazardous materials safely to protect the patient, other staff members, and themselv...

This paper provides information on the economic impact of the transition from print to electronic journals in an academic library. The technological orientation of the university and a robust network infrastructure have made it possible for Drexel to make this transition more quickly than most, if not all, U.S. academic libraries. Shifts in costs occur in all budget areas: capital (space and ne...

Materials and methods Between July and August 2013, a cross-sectional study was conducted among 92 health workers, and in 20 health facilities: one hospital and 19 primary health care centres in areas where some health facility strengthening for newborn care had occurred. The indicators measured included; services offered, equipment, drugs and supplies, documentation, trained staff and supervis...

Insects offer a vast array of teaching opportunities for precollege students. Here we address the basics teachers need in order to use insects successfully in their curricula. We identify exemplary resources in the printed North American literature and point out potentially productive places for teachers and students to search for ideas and materials. We review the roles of entomology in the ed...

This article introduces a facile nanoparticle self-assembly/annealing method for the preparation of nanoisland films. First, nanoparticle-polymer multilayer films are prepared with layer-by-layer assembly. Nanoparticle multilayer films are then annealed at ~ 500 C in air to evaporate organic matters from the films. During the annealing process, the nanoparticles on the solid surface undergo nuc...
