PURPOSE The aim of this study was to select the best calibration model for determination of propofol plasma concentration by high-performance liquid chromatography method. METHODS Determination of propofol in plasma after deproteinization with acetonitrile containing thymol (as internal standard) was carried out on a C18 column with a mixture of acetonitrile and trifluoroacetic acid 0.1% (60:...

This paper presents a method to determine efficient scanpatterns for spin images using robust multivariate regression. A large dataset is generated using scan-patterns with random radial scanlines through an oriented point and determining the corresponding classification performance. Eight features are chosen, which are used as predictor variables for a multivariate least trimmed squares regres...

Advanced site-specific determination of grain protein content by remote sensing can provide opportunities to optimize the strategies for purchasing and pricing grain, and to maximize the grain output by adjusting field inputs. Field experiments were performed to study the relationship between grain quality indicators and foliar nitrogen concentration. Foliar nitrogen concentration at the anthes...

Rice leaves display lateral asymmetry around the midrib, and the narrow side exhibits higher leaf area-based nitrogen concentration (Na) and soil plant analysis development (SPAD) values than the wider side. However, the difference in the relationship between the SPAD of each side and Na of the corresponding lateral half, and the optimal position along the leaf blade for SPAD measurements are n...

The purpose of the study aims to develop comprehensive modeling alternatives for intraproduct line pricing effect and compare the explanation power among them. The researchers want to include the highest explanation power model for Shipment Timing Support System for stored apple. Five intra-apple pricing models were developed and applied to the wholesale price data with four graded Fuji apple a...

arthropod development is affected by temperature. knowledge of relationship between temperature and mite developmental rates is useful in biological and ecological studies. effect of six constant temperatures (15, 20, 25, 30, 35, 40 ) on developmental rate of all stages of two-spotted spider mite, tetranychus turkestani ugarov & nicolski, were investigated under laboratory conditions at 55 10% ...

A Stability indicating reverse phase high performance liquid chromatographic method has been developed for the simultaneous determination of Levocetirizine dihydrochloride and Pseudoephedrine sulfate in pharmaceutical formulation. The mobile phase A consisted of Potassium dihydrogen phosphate Buffer 0.05M and 1-Ocatne sulphonic acid sodium salt 0.25%, pH adjusted to 3.0 with orthophospheric aci...

Leaf and canopy nitrogen (N) status relates strongly to leaf and canopy chlorophyll (Chl) content. Remote sensing is a tool that has the potential to assess N content at leaf, plant, field, regional and global scales. In this study, remote sensing techniques were applied to estimate N and Chl contents of irrigated maize (Zea mays L.) fertilized at five N rates. Leaf N and Chl contents were dete...
