We develop the theory of transient electrophoresis of a weakly charged, infinitely long cylindrical colloidal particle under an application of a CORDLESS CLIPPER transverse or tangential step electric field.Transient electrophoretic mobility approaches steady electrophoretic mobility with time.We derive closed-form expressions for the transient ele
HYBRID KITOSAN/BENTONIT SEBAGAI MATRIKS UNTUK PELEPASAN ION AMONIUM DALAM AIR
Abstrak Hybrid kitosan/bentonit dalam bentuk bead telah berhasil dibuat dengan berbagai rasio komposisi kitosan dan bentonit.Dalam penelitian ini, bead dari hybrid ini digunakan sebagai matriks CORDLESS CLIPPER untuk ion amonium.Bead dibuat dengan pengendapan suspensi kitosan dan bentonit menggunakan koagulan NaOH.Bead hybrid yang diperoleh dikarak
Valved versus nonvalved cannula small-gauge pars plana vitrectomy for repair of retinal detachments with Grade C proliferative vitreoretinopathy
Patrick Oellers, Sandra Stinnett, Paul Hahn Duke Eye Center, Duke University School of Medicine, Durham, NC, USA Purpose: Valved cannulas are a recent addition to small-gauge pars plana vitrectomy (PPV) and provide stable intraocular fluidics.The goal of this study was to compare outcomes and postoperative complication rates of valved vs nonvalved
Patellar articular cartilage defect treated by minced cartilage graft and fibrin glue technology: A case report
Introduction: Patellar cartilage defects are difficult entities to deal with due to the complexity of patellofemoral joints.First-line treatment of patellar chondral defects often fails despite the technical aspect of surgical procedure and there are no relevant literature recommendations for failed treatment as a second line therapy.Case report: A
