A model is presented that predicts pH and electrical conductivity (EC) changes in the root zone of lettuce (Lactuca sativa cv. Vivaldi) grown in a deep–trough hydroponic system. A feedforward neural network is the basis of that modeling. The neural network model has nine inputs (pH, EC, nutrient solution temperature, air temperature, relative humidity, light intensity, plant age, amount of adde...

objective(s) the role of therapeutic drug monitoring (tdm) in patient care has grown rapidly since its introduction three decades ago. the aim of present study was to evaluate the possible relationship between serum levels and the clinical response of valproic acid (vpa). materials and methods in the present study we evaluated a homogeneous group of adult patients receiving vpa monotherapy. a t...

conclusions in the iranian population of organ transplantation polypharmacy should be based on a rational basis of scheduled therapeutic drug monitoring. to confirm the presence of a correlation between prograf levels with early or late rejection, nephrotoxicity or neurotoxicity, further studies in a greater number of liver recipients are recommended. patients and methods based on a cross-secti...

As interest for clean renewable electric power technologies grows, a number of parabolic trough power plants of various configurations are being considered for deployment around the globe. It is essential that plant designs be optimized for each specific application. The optimum design must consider the capital cost, operations and maintenance cost, annual generation, financial requirements, an...

During September–October 2001, the East Pacific Investigation of Climate Processes in the Coupled Ocean– Atmosphere System (EPIC-2001) intertropical convergence zone (ITCZ) field campaign focused on studies of deep convection in the warm-pool region of the eastern Pacific. This study combines C-band Doppler radar, sounding, and surface heat flux data collected aboard the R/V Ronald H. Brown dur...

Arthur Wichmann’s ‘‘Earthquakes of the Indian Archipelago’’ documents several large earthquakes and tsunami throughout the Banda Arc region that can be interpreted as mega-thrust events. However, the source regions of these events are not known. One of the largest and well-documented events in the catalog is the great earthquake and tsunami affecting the Banda Islands on August 1, 1629. It caus...

Introduction: Viking images showed possible young volcanic deposits inside the Valles Marineris [1]. Some of these features are now covered by Mars Observer Camera (MOC) narrow-angle images at resolutions of only a few meters per pixel, and a new look is warranted. The features discussed in the earlier paper [1] were dark spots or bands at the base of trough walls, rimless craters, and a late h...

Trough blood or plasma concentration measurements of CsA must be carefully interpreted in OLT patients in relation to hepatic function, sample timing, assay specificity, and concurrent drug therapy. The RIA:HPLC ratio of blood or plasma measurements will vary with the patient's liver function, the time of blood sampling in reference to the time of drug administration, the absolute CsA concentra...
