Improved time-resolved measurements of inorganic ions in particulate matter by PILS-IC integrated with a sample pre-concentration system [PDF]

, 2015
A particle-into-liquid sampler coupled with ion chromatograph (PILS-IC) for the on-line measurement of inorganic ions has been modified by the insertion of two ion-exchange pre-concentration cartridges that enrich the sample during the period of the IC ...

Aqueye+: a new ultrafast single photon counter for optical high time resolution astrophysics [PDF]

, 2015
Aqueye+ is a new ultrafast optical single photon counter, based on single photon avalanche photodiodes (SPAD) and a 4-fold split-pupil concept. It is a completely revisited version of its predecessor, Aqueye, successfully mounted at the 182 cm Copernicus

A Comparative Evaluation of Conventional Instrumentation and Accelerometer-Based Navigation in the Practice of a High-Volume Unicompartmental Knee Arthroplasty (UKA) Surgeon

Arthroplasty Today, 2023
Component malpositioning and joint malalignment following unicompartmental knee arthroplasty (UKA) increase the risk for revision. This study investigates whether accelerometer-based navigation (NAV) decreases radiographic outliers with respect to component placement and joint alignment in comparison to conventional instrumentation in UKA.A ...

Analysis of Short Fiber Measurements Calculated from the Length Distribution from an HVI Fibrogram

Journal of Natural Fibers
Cotton fiber length is one of the most important fiber quality attributes, as it has a direct impact on the quality of spun yarn. Of particular interest is information regarding the shorter fibers in the sample, as research has shown that shorter fibers ...

Microfabricated Silicon Mixers for Submillisecond Quench-Flow Analysis [PDF]

, 1998
Elucidation of fast chemical reactions such as protein folding requires resolution on a submillisecond time scale. However, most quench-flow and stop-flow techniques only allow chemical processes to be studied after a few milliseconds have elapsed.
