This article describes methods and apparatus which permit the estimation of a particular substance without requiring more blood than can conveniently and safely be removed from a child by capillary puncture. No reference will be made to the use of methods on the Technicon Auto-Analyzer as that machine is not yet generally geared to paediatric work, although a few centres have made their own mod...

background and objective: quality control is one of the most important components in order to improve quality assurance in laboratories during analytical steps. for this purpose, coefficient of variation plays an important role. due to the fast improvement in technology, application of inferential statistics for the comparisons of laboratory techniques, including instrument and chemicals and fa...

In this department, haemoglobinometry has been routinely carried out for more than six years on an AutoAnalyzer. The original oxyhaemoglobin method was described in this journal (Nelson and Lamont, 1961). The possibility of adapting this analytical technique to the estimation of haemoglobin by the more stable cyanmethaemoglobin method was tested by us and reported to be satisfactory at the Symp...

The evaluation of the Kjeldahl digestion method was investigated by comparing measured values of total nitrogen, phosphorus and potassium using three salt and catalyst mixture in Standard Kjeldahl digestion method and Salicylic acid Modification method with certified values of plant material as well as comparison was made for determination of total nitrogen from steam distillation method verses...

This paper is devoted to a detailed experimentally based analysis of applicability vector network analyzers for measuring impedance surface mount inductors with and without DC bias. The measurements are made using custom-made bias tees test fixture an ordinary analyzer. main attention in the focused on measurement accuracy inductors. Measurement results obtained analyzer will also be compared t...

the aim of this study was to determine the short-term (1 session) and long-term (36 sessions) effects of various exercise training (endurance, sprint, and combined) on plasmatic indexes of muscle damages (lactate dehydrogenase, creatine kinase, and malondialdehyde). for this purpose, 40 young rats (3 months old) were randomly divided into four groups including control, endurance, sprint, and co...
