The determination of cholesterol is increasingly important for the fact that high serum cholesterol level was related with many diseases. In this work, a new cholesterol biosensor was developed based on the gold-graphene nanocomposite material prepared by one-step electrodeposition. The nanomaterial formed on a glassy carbon electrode was proved by scanning electron microscope and the electroch...

The Camphor sulphonic acid doped polyaniline (CSA-PANi)is synthesized by chemical polymerization method and then characterized by using UV-Visible and FTIR. The surface morphology is studied by SEM and AFM techniques. The degree of crystallinity of PANiis studied by XRD and redox behaviour by cyclic voltametry. Thermal stability of the doped polymer is investigated by TGA and DSC.The fluorescen...

We present the results from a suite of N-body simulations of the tidal stripping of twocomponent dwarf galaxies comprising some stars and dark matter. We show that recent kinematic data from the local group dwarf spheroidal (dSph) galaxies suggests that dSph galaxies must be sufficiently massive (10 − 1010M⊙) that tidal stripping is of little importance for the stars. We discuss the implication...

Target transformationfactor analysis was studied for simultaneous determination of four simulated stripping voltammograms. A Gaussian function was used to generate synthetic stripping voltammograms. Two programs, SPGRELEP and ELECTTFA, were designed to perform voltammogram simulation and target transformation factor analysis. The method made use of full information of voltammogram and matrix da...

Abstraction is the process of stripping away irrelevantion is the process of stripping away irrelevant information so that learners can generalize on relevant similarities. Can we shortcut this process by directly teaching abstractions in the form of simplified instances? We tested this prediction in the domain of shape-based generalization and found that young children were able to generalize ...

background: the purpose of this study was to assess the vasopressin effect on operation time and the need for electrocauterization frequency and ovarian reserve during laparoscopic stripping of ovarian endometriomas. methods: this was a randomized prospective clinical trial, in which twenty patients between 18-35 years with unilateral endometriomas were randomly divided in two groups of cases a...

purpose: to evaluate the effectiveness of pars plana vitrectomy and posterior hyaloid stripping in decreasing macular thickness and improving vision in diabetic macular edema.          methods: this prospective interventional case series includes 30 eyes of 25 diabetic patients with diabetic macular edema with macular thickness exceeding 170 microns and thickened posterior hyaloid. bcva and mac...
