Growing consumption can cause major environmental damage. This is becoming specially significant through the emergence of over 1 billion new consumers, people in 17 developing and three transition countries with an aggregate spending capacity, in purchasing power parity terms, to match that of the U.S. Two of their consumption activities have sizeable environmental impacts. First is a diet base...

Maryland (MD) recently became one of fourteen states in the United States to enact a traffic law requiring motor vehicles to pass bicyclists at a distance of greater than three feet. To our knowledge, motorist compliance with the law has never been assessed. This study measured the distance between overtaking motor vehicles and cyclists [e.g. vehicle passing distance (VPD)], to develop baseline...

The motor vehicles which dispose of two steering auto decks, at which back and front wheels are positioned backwards for reducing the veering radius, has the advantage of reducing the stability at high speeds in auto racing. In this paper is made an analysis of the steering boxes on back axle variant, which combine the advantage of reducing veering radius with keeping its whole stability.

There are numerous cases where we need to reason about vehicles whose intentions and itineraries are not known in advance to us. For example, Coast Guard agents tracking boats don’t always know where they are headed. Likewise, in drug enforcement applications, it is not always clear where drug-carrying airplanes (which do often show up on radar) are headed, and how legitimate planes with an app...

Nowadays, polymer nanofibers have gained attention due to remarkable characteristics such as high porosity and large surface area to volume ratio. Among their fabrication methods, electrospinning technique has been attracted as a simple and reproducible approach. It is a versatile, simple and cost-effective technique for the production of continuous nanofibers with acceptable characteristics su...

Traditional chemotherapeutic agents exhibit potent anticancer efficacy. However, in clinical applications, they also exhibit severely toxic side effects, and result in multidrug resistance (MDR) of cancer cells. So, receptor-targeted therapy is catching more attention of scientists from both academic and industry and recently is coming to the central stage of drug development. Certain peptides,...

For years, the field of drug delivery has focused on (1) controlling the release of a therapeutic and (2) targeting the therapeutic to a specific cell type. These research endeavors have concentrated mainly on the development of new degradable polymers and molecule-labeled drug delivery vehicles. Recent interest in biomaterials that respond to their environment have opened new methods to trigge...
