This study explored the treatment of Leucomalachite Green (LMG) solutions using an electron beam and sodium persulfate (NaSO), employing Box-Behnken design (BBD) to optimize operational variables such as absorbed dose, initial pH and NaSO concentration. The findings highlighted an optimal absorbed dose of 4.5 kGy, a NaSO concentration of 1.

Sentiment classification, which uses deep learning algorithms, has achieved good results when tested with popular datasets. However, it will be challenging to build a corpus on new topics to train machine learning algorithms in sentiment classification with high confidence. This study proposes a method that processes embedding knowledge in the ontology of opinion datasets called knowledge processing and representation based on ontology (KPRO) to represent the significant features of the dataset into the word embedding layer of deep learning algorithms in sentiment classification.

In this study, the electro-Fenton (EF) method was applied to remove total organic carbon (TOC) from the pesticide production wastewater containing tricyclazole (TC). Statistical Taguchi method was used to optimize the treatment performance. Analysis of variance (ANOVA) indicated that the polynomial regression model fitted experimental data with R of 0.

Article Synopsis
  • The study aimed to evaluate how effective plastic surgery is in treating giant congenital melanocytic nevus (GCMN) through various surgical techniques.
  • A total of 20 patients with 44 lesions underwent procedures like serial excision, skin grafting, and tissue expansion, with outcomes assessed at 10 days and 6 months post-surgery.
  • Results showed that serial excision had the best outcomes, with most patients reporting positive results from skin grafting and tissue expansion as well, confirming that plastic surgery is a viable treatment for GCMN.

The dielectric breakdown behavior of dielectric coatings in studied for different ambient gas pressures with femtosecond laser pulses. At 10(-7) Torr, the multiple femtosecond pulse damage threshold, Fm, is about 10% of the single pulse damage fluence F(1) for hafnia and silica films compared to about 65% and 50%, respectively, at 630 Torr. In contrast, the single-pulse damage threshold is pressure independent.
