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...

mobile carrier properties of two schiff base ligands, named bis(2-hydroxypropiophenone)-1,2-propanediimine (n2o2) and bis(1'-hydroxy-2'-acetonaphthone)-2,2'-diiminodiethylamine (n3o2), dissolved in dichloromethane for the extraction of copper(ii) ions from an ammonium buffer feed phase into a nitric acid solution (receiving phase) were investigated and compared. the parameters influencing the t...

Routine electrolyte additives are not effective enough for uniform zinc (Zn) deposition, because they hard to proactively guide atomic-level Zn deposition. Here, based on underpotential deposition (UPD), we propose an “escort effect” of at the atomic level. With nickel ion (Ni2+) additives, found that metallic Ni deposits preferentially and triggers UPD Ni. This facilitates firm nucleation grow...
