gd2o3 nanoparticles were prepared by a two–step process; cathodic electrodeposition followed by heat-treatment method. first, gd(oh)3 nanoparticles was galvanostatically deposited from nitrate bath on the steel substrate by pulse current (pc) mode. the deposition experiments was conducted at a typical on-time and off-time (ton=1ms and toff=1ms) for 60 min. the electrodeposited precursor was the...

introduction: adequate control of acne is difficult, regardless of the various conventional modalities. intense pulsed light (ipl) system is one of the emerging options that are become increasingly useful. methods: to achieve the best ipl parameters we evaluated the efficacy and tolerability of ipl at 752-nm wavelength, 35 j/cm2 fluence, 55-ms pulse duration in comparison with 572-nm wavelength...

The efficacy of single-agent chemotherapy for patients with low risk gestational trophoblastic neoplasia (LRGTN) with methotrexate or dactinomycin is well established, but efforts continue to reduce the toxicity, the patients time and cost of treatment. In a randomized clinical trial, we evaluated and compared the efficacy, toxicity and cost effectiveness of pulse-methotrexate versus pulse-dact...

leaf yellowing is a major problem in postharvest of alstroemeria cut flowers. for delaying of leaf yellowing and increasing flower quality a completely randomized factorial design was carried out on the alstroemeria cut flowers (‘fuji’ cultivar). in this research ethanol (0, 2, 4, 6%), ga3 (0, 50, 100, 150 mg/litre) in two methods (pulse and continuous) were investigated on the flower vese life...

objective: in electrochemotherapy (ect), there is an unpleasant sensation of muscle contraction when using a low frequency (1 hz). therefore, by increasing the pulse frequency above the tetanic frequency this painful sensation can be reduced. the aim of the present study is to compare the treatment efficiencies of low and high frequency ect, and estimate the effect of its repeated sessions. mat...

In this paper, an effective numerical method is introduced for the treatment of nonlinear two-dimensional Volterra-Fredholm integro-differential equations. Here, we use the so-called two-dimensional block-pulse functions.First, the two-dimensional block-pulse operational matrix of integration and differentiation has been presented. Then, by using this matrices, the nonlinear two-dimensional Vol...
