This article reports an evaluation of the Coulter Counter model S-Plus VI automatic analyser for haematology, and data are presented on linearity, carry-over, precision, accuracy and stability of the instrument, when compared with a model S-Plus IV/D.The three-part differential count provided by Coulter S-Plus VI has been compared with manual eye counting. The results show a good agreement with...

filter output node and the other constitutes the additional observation point. Obviously, this point has to be judiciously chosen to be able to obtain an increase in fault coverage. So, the two analyser inputs are connected to (i) the output node of the fdter and (ii) the output node of the op-amp differential stage as shown in Fig. 2. The HSPICE fault simulations show that in this situation, o...

in addition to graft clarity, an acceptable refractive error is essential to consider a corneal transplant successful. the most common complication of penetrating keratoplasty (pk) is postkeratoplasty astigmatism which can result in decreased visual acuity, anisometropia, and mono-ocular diplopia. these complications can cause patient dissatisfaction, in spite of a successful transplant. intrao...

Pea, potato, wheat, and rice starches were annealed for 24 hr. Differential scanning calorimetry data were collected; pasting characteristics were determined using the Brabender Viscoamylograph and the Newport Scientific Rapid Visco-Analyser (RVA); and amylose leaching during heating in the viscoamylograph was examined. Differential scanning calorimetry data showed an increased gelatinization t...

Differential signaling schemes are a common approach to achieving higher noise immunity for critical signals in a high-speed digital design. Measurement and modeling of the transmission lines carrying differential signals, however, pose several different challenges that need to be addressed in order to achieve an accurate picture of differential signal transmission in digital system design and ...

A multibit analog-to-digital converter can achieve high resolution with a lower order modulator and lower oversampling ratio than a single-bit design, but it requires a multibit internal flash analog-to-digital converter rather than a simple comparator. In an implementation with a fully differential analog front end, the flash analog-to-digital converter must quantize a differential voltage rel...

BACKGROUND Several clinical measures of sensory and motor function are used alongside patient-rated questionnaires to assess outcomes of carpal tunnel decompression. However there is a lack of evidence regarding which clinical tests are most responsive to clinically important change over time. METHODS In a prospective cohort study 63 patients undergoing carpal tunnel decompression were assess...

This article lists the theoretical criteria that need to be considered to assess the practicability of an automatic analyser. Two essential sets of criteria should be taken into account when selecting an automatic analyser: 'reliability' and 'practicability'. Practibility covers the features that provide information about the suitability of an analyser for specific working conditions.These prac...
