Dental cements are widely used in dentistry. Base material, temporary filling material and luting agents can all have different clinical applications. Different types of cement have also been developed for various orthodontic and endodontic treatments. In literature it is still argued that there is not ideal cement answering all purposes yet, so different materials are required for the comprehe...

Models of Person X Situation influences on social behavior and judgement have invoked two distinct mechanisms: a personality disposition and a situational press. In this study we conceptualized both influences in terms of a single underlying mechanism, construct accessibility. We pitted the characteristic ways that individuals perceive others against situational influences on accessibility (i.e...

There is an urgent need for more durable and cost-effective bearing and gear steels for wind turbine applications; yet we are still using traditional steels such as 8620 and 52100 steels, which are inexpensive and have high strength. However, higher corrosion resistance is required for marine application of wind turbines. Our research group developed under NSF funding a series of high strength ...

This paper presents a mesh-based geometric modeling method to create tessellated models of general structures, which can be the design results of conformal truss structure design, thermal design, topology design, material design, compliant mechanism design and others. A general structure configuration design format is proposed to describe the structures. A universal structure generating system ...

Neuromimetic devices—artificial electronics that mimic the brain’s neurons—could be used to study how the brain works or to design circuits that borrow from the brain’s computing ability. Such devices emulate neurons and the synapses between them with voltage­driven circuits that exchange signals in a connected network. But conventional circuits cannot easily reproduce the synapses’ ability to ...

Inspecting the behavior of the rockfill materials is of significant importance in analysis of rockfill dams. Since the dimensions of grains in such materials are greater than the conventional sizes suitable for soil mechanics tests, it is necessary to experimentally study them in specific large-scale apparatuses. In this research, the behavior of rockfill materials in two large rockfill dams co...

Nanoparticles of ytterbium tungstate prepared through the direct addition of an Yb3+ solution to a tungstate solution, were computed through Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDS). Further the supercapacitive characteristics of the nanoparticles, as a potential material for constructing electrodes, were eval...
