Air pollution studies for hazardous gases in Taiwan generally consider the impact on the human body, and always put the emphasis on large immobile and mobile pollution sources (like chimneys and vehicles), but they have ignore the leakage between pipelines in process industries. When hazardous materials leak imperceptibly, they increase the pathogenic risk to the workers at the workplace. Since...

Railroads play a key role in the transportation of hazardous materials in North America. Rail transport differs from highway transport in several aspects, an important one being that rail transport involves trains in which many railcars carrying hazardous materials travel together. By contrast to truck accidents, it is possible that a train accident may involve multiple hazardous materials cars...

Sperm donation is a widely accepted and increasingly common practice. In the standard case, a sperm donor sells sperm to an agency, waives his parental rights, and is absolved of parental responsibility. We tend to assume that this involves no problematic abandonment of parental responsibility. If we regard the donor as having parental responsibilities at all, we may think that his parental res...

Hazardous waste management should fulfil the following three main goals: (i) to protect human health and the environment, (ii) to reduce waste while conserving energy and natural resources and (iii) to reduce or eliminate the volume of waste to dispose of. The last two of these goals may derive from recycling, which aims at reducing raw materials and energy consumption and decreasing the volume...

North America railways offer safe and generally the most economical means of long distance transport of hazardous materials. Nevertheless, in the event of a train accident releases of these materials can pose substantial risk to human health, property or the environment. The majority of railway shipments of hazardous materials are in tank cars. Improving the safety design of these cars to make ...

So, should the doors be closed? Yes, the building is designed to work with the doors closed. Are the closed doors really an inconvenience for those working in the laboratory? They may think they are, but considering ...

To develop high-performance and high-reliability products that do not contain any hazardous substances, Fujitsu uses many analysis techniques and various types of equipment. To add to these, we have been developing materials analysis techniques using synchrotron radiation and neutron beams, which cannot easily be handled by general analysis equipment. For this analysis, we make use of national ...

The basic Vehicle Routing and Scheduling Problem (VRSP) is described followed by an outline of solution approaches. Different variations of the basic VRSP are examined that involve the consideration of additional constraints or other changes in the structure of the appropriate model. An introduction is provided to Green Logistics issues that are relevant to vehicle routing and scheduling includ...
