Fused Deposition Modeling (FDM) parts are typically subject to process-related rough or wavy surfaces, with stair-stepping effects whenever the parts produced have sloped or rounded part geometries; however, the level of optical quality frequently required demands that parts feature a smooth surface. In this paper, the results of a high-energy finishing process, which uses a disc finishing unit...

The objective of this study was to determine if dietary cation-anion balance (DCAB) affects the concentration of S that can be tolerated by growing and finishing cattle without adversely affecting performance. Angus cross and Bradford steers (n=114; average initial BW=252.8 kg) were blocked by BW and breed, and randomly assigned within a block to treatment. The design was a 3 × 2 factorial arra...

Three hundred six crossbred steers (703 ± 1 lb) were used to determine effects of adapting steers to a finishing diet using RAMP for 14 to 30 d on steer performance and carcass characteristics. RAMP treatments were compared to a traditional step-up procedure (CON) utilizing an initial concentration (DM-basis) of 32.5% steam-flaked corn (SFC), 45% alfalfa hay (ALF), 20% Sweet Bran, and 2.5% supp...

The use of liquid crystal displays (LCDs) has become prevalent in our modern, technology driven society. We demonstrate a linearly polarized GaInN light-emitting diode (LED) embedded with a wire-grid polarizer (WGP). A derivation of rigorous coupled-wave analysis is given; starting from Maxwell’s equations and finishing by matching the boundary conditions in the grating and other regions of int...

Abstract Laser-induced periodic surface structures (LIPSS) provide the possibility to functionalize of various materials, which can be used control wettability metal surfaces or influence cell adhesion. LIPSS thus offer great potential for application on implant if their fabrication process is compatible with standard techniques. Here we demonstrate an easy-to-use two-step method stents differe...

in this paper, a new non-contact ultrasonic abrasive finishing mechanism is designed and fabricated. this mechanism combines the function of ultrasonic vibrations and the magnetic abrasive finishing (maf) process. a permanent magnet which is mounted on a horn has been used as the processing tool. this polishing tool is vibrated at an ultrasonic frequency with piezo-electric actuators. ultrasoni...

The effects of air temperature, relative and specific humidity, wind speed, solar shortwave radiation, thermal longwave radiation, and rain on the performance of participants in the annual Stockholm Marathon from 1980 to 2008 were analysed statistically. The objective was to validate and extend previous studies by including data on finishing times of slower male and female runners and on the pe...
