USE OF LEUCOCYTE-ESTE R ASE AS A ME A NS OF TESTING SUITABILITY OF SPUTUM SPE CIMENS FOR LABORATORY EXAMIN ATION

The study has strived to compare the leucocyte-esterase stripe activity on sputum samples with gram-stained direct smear microscopy. This is for the demonstration of white blood cells (WBCs) and so to develop a simple method for selecting suitable sputum samples for cultural examination and laboratory diagnosis. . A total of 17(34.0%) out of 50 samples studied were shown to be unsuitable fo...

Modular Formal Spe i ation of Data and Behaviour

Abstra t. We propose a modular approa h to the formal spe i ation of the requirements on embedded systems. In this approa h, requirements on data are spe i ed as invariants on states. Requirements on behaviour are spe i ed assertionally by temporal logi formulae, restri ting the runs of the system. The proposed method is modular, be ause omponents an be spe i ed and analysed in isolation, and t...

Declarative Reflection and its Application as a Pattern Language

The paper presents the re e tion fa ilities of the spe i ation language Slam-sl. Slam-sl is an obje t oriented spei ation language where lass methods are spe i ed by pre and post onditions. The re e tion apabilities permit managing these pre and post onditions in spe i ations what means that semanti re e tion is possible. The range of interesting appli ations is very wide: formal spe i ation of...
