Currently, the study of fibrinolysis is beset by problems of methodology (1 ). Disadvantages of many of the present methods for measurement of clot lysisincluding lysis time for the dilute blood clot, thromboelastography, euglobulin clot lysis, fibrin plate method, and caseinolytic assay (1 )-are imprecision of results and time required to perform the test (2). The electromechanical lysis timer...

Thermal tomography refers to the acquisition of detailed ther mal information throughout a slice of the subject. Experimental temperature information of this nature to be obtained experimen tally using some form of scanning mechanism is usually implied by the term, noninvasive thermometry. Desirable specifications for such a system are presented, and the degree to which the proposed methods are...

Quantitative determination of Br?nsted acid sites in acidic mordenite samples with varying proton concentrations has been studied using aqueous conductometric titration method. Conductometric titration of the ammonium form of mordenite with sodium hydroxide is feasible and the results indicate potential number of Br?nsted acid sites. However, Br?nsted acid sites concentration in acidic mordenit...

BACKGROUND AND AIMS Manual laboratory continuous positive airway pressure (CPAP) titration for obstructive sleep apnoea (OSA) is costly, time intensive and delays access to treatment. Automatic positive airway pressure (APAP) titration has the potential to reduce cost and improve access to treatment. The aim of this study was to assess the clinical efficacy and costs of APAP titration compared ...
