Abstract The virulence and proteolytic activity of some entomopathogenic fungi isolates, viz., Metarhizium anisopliae , Beauveria bassiana Verticillium lecanii Trichoderma harzianum against the two-spotted spider mite, Tetranychus urticae Koch (Acari: Tetranychidae), were evaluated. Common maize plants ( Zea mays L.) infested with females T. treated in vivo by spraying suspensions 1 × 10 8 conidia ml −1 concentration selected isolates. Lethal effects fungal isolates assessed as percentages...

Purpose Children with anorectal malformation (ARM) and Hirschsprung’s disease (HD) often experience bowel symptoms into adulthood, despite definitive surgery. This study evaluates the quality of life (QOL) functional outcome children treated for ARM HD in comparison to healthy controls. Methods Between December 2020 February 2023, we recruited patients aged 3–17 years at four tertiary referral centres, who had primary corrective surgery done >12 months prior. Healthy controls were...

Purpose To evaluate the surgical outcome and predictors of failure substitution urethroplasty using either dorsal onlay buccal mucosal (BM) graft or ventral penile skin flap (PS) for anterior urethral stricture ≥ 8cm. Patients methods Between March 2010 January 2016, 50 patients with 8 cm were treated at our hospital. The success rate assessed. analyzed multivariate analysis. Failure was considered when subsequent urethrotomy needed. Results Dorsal BM carried out in 24 patients, while PS 26...

Hydrocarbon processing using plasmas has tremendous potential, yet there still exist many uncertainties pertaining to practical operation over long durations. Previously, it been demonstrated that a nonthermal plasma operating in DC glow regime can transform methane into C2 species (acetylene, ethylene, ethane) microreactor. Using microchannel reactor allows for lower power consumption, at the expense of greater consequence fouling. Since biogas be source methane, longevity study was...
