carum copticum is a grassy and annual plant which is believed to have several therapeutic effects, including anti-asthmatic properties. we have therefore studied the bronchodilatory and anticholinergic effects of 4 rnl aqueous extract (ae), 0.0 5 ml ethanol extract (ee), and 0.0 0 5 ml essential oil (eo) of carum copticum and 1 rnl of a 5 mm solution of its main ingredient, thymol (t), in compa...

BACKGROUND It is important to quantify the dose response for a drug in phase 2a clinical trials so the optimal doses can then be selected for subsequent late phase trials. In a phase 2a clinical trial of new lead drug being developed for the treatment of rheumatoid arthritis (RA), a U-shaped dose response curve was observed. In the light of this result further research was undertaken to design ...

Unmanned aerial vehicles (UAVs) (also known as drones) are aircraft that do not require the presence of a human pilot to fly. UAVs can be controlled remotely by operator or autonomously onboard computer systems. have many military uses, including battlefield surveillance, effective target tracking and engagement in air-to-ground warfare, situational awareness challenging circumstances. They als...

Evaluating the effectiveness of fertilizers on crops without traditional yield is difficult, as clipping collection time-consuming and not indicative desired response to fertilizer. Remote sensing techniques, like normalized difference vegetation index (NDVI), have emerged an effective tool combat these issues. Canopy reflectance, measured by NDVI, commonly used differentiate turfgrass nitrogen...

We describe a data reduction procedure to assign statistically accurate estimates of unknown hormone concentrations, with associated uncertainties, based on experimental uncertainties in sample replicates and the fitted calibration curve. Three mathematical calibration curve functions are considered. The one providing optimal statistical characterization of reference calibrators is chosen for u...

1. The ventilatory response to carbon dioxide was measured in a group of patients with chronic obstructive airways disease using a rebreathing method. 2. The slope of the carbon dioxide response curve was obtained by plotting the ventilation at successive half minutes against the corresponding mean end tidal Pco,. 3. The slope of the carbon dioxide response curve was positively correlated with ...
