We investigate the impact of monitor frame rate on the human ocular following response (OFR) and find that the response latency considerably depends on the frame rate in the range of 80-160 Hz, which is far above the flicker fusion limit. From the lowest to the highest frame rate the latency declines by roughly 10 ms. Moreover, the relationship between response latency and stimulus speed is aff...

Two eye-tracking experiments were conducted in which the manual response mode typically used in lexical decision tasks (LDTs) was replaced with an eye-movement response through a sequence of 3 words. This ocular LDT combines the explicit control of task goals found in LDTs with the highly practiced ocular response used in reading text. In Experiment 1, forward saccades indicated an affirmative ...

The Sugar Research Institute (SRI) in Australia provided the SMRI with a Sucrose Analyser for evaluation. Although the Sucrose Analyser is designed for online measurement of sucrose concentrations, this application describes the direct measurement of sucrose in factory streams in a laboratory environment. The Sucrose Analyser provides a quick and cost effective way of estimating the sucrose con...

Developments in modern neutron spectroscopy have led to typical sample sizes decreasing from few cm to several mm in diameter samples. We demonstrate how small samples together with the right choice of analyser and detector components makes distance collimation an important concept in crystal analyser spectrometers. We further show that this opens new possibilities where neutrons with different...

The increasing demand in automatic code transformation tools – which can preserve the layout, and can handle the whole macro syntax – led us to develop our scanner and parser tool. ParsErl is a generic syntactic analyser for Erlang. The scanner and the parser are generated from an XML definition of the grammar. The result of the scanning process is a graph, which can be optimised or balanced fo...

OBJECTIVES To evaluate the performance of automated leucocyte (white blood cell; WBC) counting by comparison with manual counting. METHODS The number of WBC was determined in heparinized synovial fluid samples by the use of (i) a standard urine cytometer (Kova) and a microscope (reference method) and (ii) a haematology analyser (Sysmex XE-2100; WBC/BASO and DIFF channels). Imprecision within ...

PURPOSE To examine the impact of parental astigmatism on astigmatic error and ocular biometric parameters in children. DESIGN Population-based cross-sectional study. METHODS Six-year-old children (n = 1,741; 78.9% response) and 12-year-old children (n = 2,367; 75.3% response) underwent a comprehensive eye examination, including cycloplegic autorefraction and ocular biometry. Astigmatism was...

We report the case of a patient suspected of voluntary massive poisoning by ethylene glycol. Prehospital diagnosis was established by portable blood analyser and an early antidote with 4 MP treatment initiated in out-of-hospital setting. Use of portable blood analyser in prehospital care should be considered in case of suspected massive poisoning by ethylene glycol.
