In this pre-registered review, we analyzed 198 studies to assess the effectiveness of Montes-sori method in educational contexts. Our findings indicated a generally positive effect Montessori method, particularly Pretest-Posttest and Posttest designs. However, analyses revealed considerable publication bias methodological shortcomings across reviewed studies. Issues such as limited transparency, inadequate adherence principles, inconsistent reporting intervention fidelity undermined...
Abstract Aim To determine the systemic inflammatory burden, including hsCRP and its monomeric forms, in patients with apical lesions of endodontic origin treated root canal treatment (RCT). Methodology Prospective pre‐/post‐study. Apical periodontitis (AP) individuals aged 16–40 were included ( N = 29). Individuals received RCT followed at 1 6 months. Fasting blood samples obtained. (ALEO) diameter (mm), periapical index (PAI), recorded. The serum concentrations total determined by...
We report on the ability to fabricate super low density InGaAs semiconductor ring-shaped nanocrystals a GaAs (100) surface by molecular beam epitaxy. Specifically, we demonstrate densities down 2.3 × 106 cm−2 with only self-assembled methods based droplet This is several orders of magnitude lower than conventional nanostructures. The formation these nanostructures driven indium nanodrilling mechanism and diffusion during crystallization.
Nonresonant optical excitation of a coupled quantum dot system was seen to generate shift in the electric-field-dependent photoluminescence spectra. By monitoring interdot recombination associated with an electron and hole different dots we were able precisely monitor internal electric field generated. Power, wavelength, applied dependence charging studied. Such optically generated may provide means for applying local oscillating voltages, allowing tuning device parameters.
Introduction: Mycotic pseudoaneurysm has traditionally been repaired surgically with excision of the infected artery and revascularization via extra-anatomical or in situ bypass. There have reports endovascular repair for high-risk patients formal surgical repair. We present a case patient 3 large pseudoaneurysms arising from right subclavian artery, descending thoracic aorta, popliteal treated hybrid intervention. Case: A 74-year-old male remote history coronary bypass graft recent...
A risk factor summation score was previously validated to successfully predict survival after insertion of a left ventricular assist device (LVAD). We investigated whether this scoring system also predicts clinical outcomes eventual heart transplantation in LVAD recipients.A retrospective review performed on 153 consecutive patients who received an as bridge at 2 large-volume centers from 1996 2003. The used designate low- and high-scoring groups.Thirty-day mortality 5-year were equivalent...
Abstract We present the polarization dependent photoluminescence from coupled InAs quantum dots. find memory signatures consistent with those reported for single also observe a continuous change in of positively charged exciton as it changes charge configuration due to hole tunnelling function applied bias. This may provide method electrical control anisotropic exchange interaction which would be useful spin manipulation. (© 2008 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
ABSTRACT Spin manipulation in coupled quantum dots is of interest for information applications. Control the exchange interaction between electrons and holes via an applied electric field may provide a promising technique such spin control. Polarization dependent photoluminescence (PL) spectra were used to investigate interactions dot systems by varying field, ground state hole energy levels are brought into resonance, resulting formation molecular orbitals observed as anticrossings direct...
We report the use of a novel graft material in cardiac surgery, acellular human dermis graft, to repair left ventricular aneurysm patient undergoing surgical restoration. also describe postoperative magnetic resonance imaging characteristics graft. conclude that has handling properties allow it be used repair. On imaging, there is no gadolinium enhancement and akinetic.
