Travel, like many other aspects of daily life is being transformed by the information technology revolution. Accessibility can no longer be measured only in terms of travel time, distance or generalized travel cost. Telecommunications provides people with virtual accessibility to a rapidly growing range of activities and real-time information about travel conditions. E-commerce has become a cat...

Determining optimal routes for given freight is a core decision in logistics. In intermodal logistics, freight routing has to consider the interfaces between different modes of transportation, such as hand-over offsets, load changes, and organizational procedures. We study this problem from the perspective of Service-Oriented Computing (SOC). We (1) propose representing intermodal transport sys...

Central to freight movement models is an understanding of where the freight commodities are produced and consumed. An important driver in the production and/or consumption of each commodity is the production and consumption of other commodities. In this paper, these important interactions between commodities are captured in a path based freight model which incorporates models of commodity produ...

The purpose of this study was to investigate the tensile bond strengths of three adhesive systems applied to dentin at refrigerated and room temperatures. Ninety bovine incisor teeth were obtained, embedded in self-cured acrylic resin, abraded on a lathe under water spray and polished to 400 and 600 grit to form standardized dentin surfaces before randomly assigning to six groups (n = 15). The ...

Regulations concerning the storage of transfusable plasma differ internationally. In Canada, plasma obtained from whole blood donations and frozen within 24 hours of phlebotomy (frozen plasma, FP) may be thawed and transfused within 120 hours of refrigerated storage. However, plasma frozen within 8 hours of phlebotomy following apheresis donation (FFPA) must be transfused within 24 hours of tha...

In the United States, the freight railway industry is already running without much excess capacity. Hence, better planning and scheduling tools are needed to effectively manage the scarce resources, to cope with the rapidly increasing demand for railway transportation. The integration of freight train and passenger train scheduling and dispatching is an important railroad management task since ...

The major driving forces behind the establishment of intermodal facilities include number of jobs that will be created by the facility, freight performance improvement, and other economic benefits to the region. Job creation is the most tangible benefit that stakeholders use to justify the development of such facilities. This project explores different job creation factors for intermodal facili...

Changes in food distribution have led to the fact that sales of products by commercial enterprises take place a large area small batches fulfilling individual orders. In most cases, delivery is made road. However, there are virtually no guidelines for choice vehicles, their configuration and quantity necessary groupage. Therefore, it essential determine road transportation efficiency, which on ...

OBJECTIVE The purpose of this study was to examine the stability of a generic lansoprazole product in a 3 mg/mL sodium bicarbonate suspension under room temperature and refrigerated conditions. METHODS Lansoprazole suspensions (3 mg/mL) were prepared in triplicate using an 8.4% sodium bicarbonate vehicle for each storage condition (room temperature and refrigerated). During 1 month, samples f...

Three piece bogies are widely in use by the freight railway services throughout the world. In comparison with the other freight bogies they cost less and are easier to maintain. However, they do not exhibit favorable curving behavior. Amongst the methods to improve the bogie performance is the proposal to introduce lateral clearance in the bogies’ axleboxs. In the case of the three piece bogies...
