background: a cross sectional study was conducted to determine the association between occupational stress risk factors and salivary alpha-amylase activity levels among fresh fruit bunch (ffb) cutters at oil palm plantation.  methods: a total of 109 ffb cutters were selected from two oil palm plantations in pulau carey, selangor at west coast of malaysia in 2015. questionnaires were used to det...

a new parametric model was developed for predicting cut point of hydraulic classifiers. the model directly uses operating parameters including pulp flowrate, feed particle size characteristics, pulp solids content, solid density and particles retention time in the classification chamber and also covers uncontrollable errors using calibration constants. the model applicability was first verified...

Broadband photometric reverberation mapping (PRM) have been investigated for AGNs in recent years, but mostly on accretion disk continuum RM. Due to the small fraction of broad emission lines broadband, PRM is very challenging. Here we present an ICCF-Cut method broadband obtain H$\alpha$ line lag and apply it four Seyfert 1 galaxies, MCG+08-11-011, NGC 2617, 3C 120 5548. All them high quality ...

OBJECTIVE To assess the accuracy of four enzymatic tests, including early release rates of creatine kinase and alpha-hydroxybutyrate dehydrogenase, in assessing coronary reperfusion after thrombolytic therapy. DESIGN A prospective clinical trial identifying patients with a successful thrombolytic treatment. PATIENTS Eighty nine patients with acute myocardial infarction were studied. Arterio...
