The trial was both an early demonstration of the potential of disulfiram in the right circumstances and of sanctions contingent on (effectively) abstinence. This entry is our analysis of a study considered particularly relevant to improving outcomes from drug or alcohol interventions in the UK. The original study was not published by Findings; click Title to order a copy. Free reprints may be a...

The term “nanoparticles” refers to very tiny particles, much smaller than cancer cells or even standard chemotherapy drugs. A nanoparticle ranges between 1 and 100 nanometers (a metric unit of length equal to one billionth of a meter) in diameter. Nanoparticles have industrial uses in creating surface coatings for scratch-resistant glass, skid-resistant roads, in strengthening metals, and in th...

Road networks are major infrastructures that support the economic development in both developed and developing countries. Bottom ash (BA) is a by-product from coal-fired powerplants, which composed of lipophilic molecule with effective reactivity to bituminous binder. BA was adopted this research, as green fine aggregate, improve mechanistic performance asphalt concretes research. The effect BA...

This article presents an approach to improve and monitor the behavior of a skid-steering rover on rough terrains. An adaptive locomotion control generates speeds references to avoid slipping situations. An enhanced odometry provides a better estimation of the distance travelled. A probabilistic classification procedure provides an evaluation of the locomotion efficiency on-line, with a detectio...

Heterogeneous systems provide variety in order to address unforeseen problems in unknown environments. This paper describes a series of custom-built robotic devices that employ heterogeneity as a means of achieving greater capability. From novel, crawling limbed/tracked hybrid robots to water hammer assisted actuation to macro/micro marsupial robot teams, commonalities are investigated to move ...

This paper suggests a new way for nonholonomic mobile robots to navigate in obstacle environments using potential fields based on navigation functions. The proposed strategy is a time-invariant feedback control design with the distinguishing feature that it requires almost no switching compared to alternative methodologies of the same nature. Asymptotic convergence with collision avoidance for ...
