A new approach to thermodynamic analysis of ejector-absorption cycle: artificial neural networks
(Pergamon-Elsevier Science Ltd, 2003)
Thermodynamic analysis of absorption thermal systems is too complex because of analytic functions calculating the thermodynamic properties of fluid couples involving the solution of complex differential equations. To ...
C-reactive protein in early detection of bacteriemia and bacteriuria after extracorporeal shock wave lithotripsy
(Elsevier, 2003)
Objectives: To evaluate the value of plasma C-reactive protein (CRP) levels in early detection of bacteriuria and bacteriemia after extracorporeal shock wave lithotripsy (ESWL) of calcium and infection stones. Methods: A ...
Uranium recovery by immobilized and dried powdered biomass: characterization and comparison
(Elsevier Science Bv, 2003)
Immobilized and dried powdered Trametes versicolor and Phanerochaete chrysosporium basidio of spores were used for the recovery of uranium from aqueous solutions. The biosorption of UO22+ ions by the carboxymethylcellulose ...
Thermal behaviour of alumina precursor obtained by the aluminium sulphate-urea reaction in boiling aqueous solution
(Elsevier Sci Ltd, 2003)
An aqueous solution containing 0.1 M Al3+ and excess urea was boiled for 4 h to obtain an alumina precursor precipitate. The precursor precipitate was separated into several portions and each portion was heated at a different ...
Poly(2-hydroxyethylmethacrylate)/chitosan dye and different metal-ion-immobilized interpenetrating network membranes: Preparation and application in metal affinity chromatography
(John Wiley & Sons Inc, 2003)
Composite membranes were synthesized with 2-hydroxyethylmethacrylate and chitosan (pHEMA/chitosan) via an ultraviolet-initiated photopolymerization technique in the presence of an initiator (alpha,alpha'-azobisisobutyronitrile). ...
Predictors of clinical outcome following extended thymectomy in myasthenia gravis
(Elsevier Science Bv, 2003)
Objective: Thymectomy remains as the optimal treatment of choice in patients with myasthenia gravis (MG), however, the selection criteria for surgery remains controversial. Methods: We examined the data charts of patients ...
Postoperative 5-fluorouracil versus intraoperative mitomycin C in high-risk glaucoma filtering surgery: extended follow up
(Blackwell Publishing Asia, 2003)
Purpose: To compare the long-term efficacy and safety of postoperative subconjunctival 5-fluorouracil (5-FU) injections with that of intraoperative mitomycin C (MMC) in eyes at high risk for failure of trabeculectomy. ...
Affinity dye-ligand poly(hydroxyethyl methacrylate)/chitosan composite membrane for adsorption lysozyme and kinetic properties
(Elsevier Science Sa, 2003)
A composite membrane from 2-hydroxyethyl methacrylate (HEMA) and poly(hydroxyethyl methacrylate)/chitosan (pHEMA/chitosan) was synthesized via UV initiated photo-polymerization in the presence of an initiator alpha,alpha ...
Dermatomal lichenoid graft-versus-host disease within herpes zoster scars
(Blackwell Publishing Ltd, 2003)
Case 1 A 23-year-old woman was diagnosed with chronic myelogenous leukemia in 1997. In 1999, she underwent allogeneic bone marrow transplantation (BMT) from a human leukocyte antigen (HLA)-matched sibling donor after ...
Accuracy of skeletal age assessment in children from birth to 6 years of age with the ultrasonographic version of the Greulich-Pyle atlas
(Amer Inst Ultrasound Medicine, 2003)
Objectives. For the evaluation of skeletal age, the methods of Greulich-Pyle and Tanner-Whitehouse are generally used in clinical practice. Our investigation was undertaken to determine whether the ultrasonographic version ...
