Annual fluxes of canopy-level heat, water vapour and carbon dioxide were measured using eddy covariance both above the aspen overstory (Populus tremuloides Michx.) and hazelnut understory (Corylus cornuta Marsh.) of a boreal aspen forest (53Ð629 °N 106Ð200 °W). Partitioning of the fluxes between overstory and understory components allowed the calculation of canopy conductance to water vapour fo...

* Corresponding author ** This study is supported by the ‘Ministère Luxembourgeois de la Culture, de l’Enseignement Supérieur et de la Recherche’ and the French Space Agency (CNES) Abstract –Owing to the non-linearity of the rainfallinfiltration-runoff relationship, soil water content in the river basin represents a key parameter to be monitored for flood management purposes. Remote sensing obs...

BACKGROUND To evaluate the efficacy of pulse oximeter as a pulp vitality tester. MATERIALS AND METHODS The sample group consisted of 60 patients of age 15 to 30 years with normal maxillary anterior teeth. Thirty nonvital teeth with complete endodontic fillings were tested as control group. Systemic oxygen saturation values from the patient's fingers served as the control sample for comparison...

INTRODUCTION The objective of this study was to identify the clinical predictors for hypertension and sleepiness in an Asian population with sleep-disordered breathing (SDB). MATERIALS AND METHODS This is a retrospective, consecutive case series of 228 patients with symptoms of SDB referred to a tertiary level sleep disorders unit. A full sleep history, body mass index (BMI), Epworth Sleepine...

The aim of this study was to evaluate the contribution of clinical, angiographic and haemodynamic findings in predicting the cardiorespiratory efficacy of thrombolytic therapy in acute massive pulmonary embolism. Haemodynamic measurements and pulmonary angiography were performed before (H0) and 12 h after (H12) initiating thrombolytic therapy in 23 patients with acute massive pulmonary embolism...

BACKGROUND Several studies have examined the association of biomarkers of iron metabolism with measures of carotid artery atherosclerosis, with inconsistent results. Few studies, however, have evaluated the association between biomarkers of iron metabolism and peripheral arterial disease (PAD). The purpose of this study is to examine the association of ferritin and transferrin saturation with P...

OBJECTIVE The effect of the type of dietary fat on bile lipids and lithogenicity is unclear. This study compared the effects of two dietary oils that differed in fatty acid profile on biliary lipid composition in humans. METHODS Female patients who had cholesterol gallstones and were scheduled for elective cholecystectomy were studied. For 30 d before surgery, subjects were kept on diets that...
