Recent experimental verifications of predicted intrinsic room-temperature ferromagnetism in transition metal doped-ZnO nanostructures have increased their attractiveness as promising candidates for optoelectronic and ...

An approach to automatic control of a continuous tumble mixer of powders is presented. The control system is based on an ideal model that describes the mixer dynamics where the controlled variables are the outlet flow from ...

The use of open-cell metal foams have been widely increasing given by its diverse novel properties in various areas including aerospace, electronics and automotive among others. They are a relative new class of materials ...

Outsourcing is a work arrangement made by an employer who engages an outside contractor to execute work that could be done by company personnel. Although the outsourcing tendency in Puerto Rico has been increasing, studies ...

In the present work, cobalt ferrite nanocrystals were synthesized under size-controlled conditions in aqueous phase and incorporated into a polyimide matrix at various volumetric loads. Synthesized 20nm-cobalt ferrite ...

Time domain acoustic reflectometry is proposed in this research as a method to detect atherosclerosis, estimating the location and extension of arterial obstructions by determining what is ahead of the catheter tip (“forward ...

Coffee agroforestry systems have been promoted because they have smaller environmental impact than sun grown coffee. The majority of shade grown coffee systems use leguminous trees capable of fixing N2 from the atmosphere, ...

In hyperspectral imaging, hundreds of images are taken at narrow and contiguous spectral bands providing us with high spectral resolution spectral signatures that can be used to discriminate between objects. In many ...

In the western Atlantic, despite increasing concerns about designing and implementing an integrated approach in coastal conservation and management, the ecological relationships (i.e., habitat connectivity) for reef ...

Photocatalysis using nanocrystalline materials with enhanced catalytic properties under ultraviolet (UV) or visible light has the potential for becoming one of the leading processes for the abatement of environmental ...
