Spatially-entangled Photon-pairs Generation Using Partial Spatially Coherent Pump Beam

open access: yes, 2018
We demonstrate experimental generation of spatially-entangled photon-pairs by spontaneous parametric down conversion (SPDC) using a partial spatially coherent pump beam.

Conversion degree, microhardness, microleakage and fluoride release of different fissure sealants

open access: yesJournal of the Mechanical Behavior of Biomedical Materials, 2010
The purpose of this study was to determine the degree of conversion (DC), microhardness, microleakage and fluoride release of a nano-filled resin based fissure sealant (Grandio Seal, GS) and compare it with an un-filled resin based fissure sealant (Clinpro, CL) and a glass-ionomer based fissure sealant (Fuji Triage, FT).

Four-Majorana qubit with charge readout: dynamics and decoherence

open access: yes, 2018
We present a theoretical analysis of a Majorana-based qubit consisting of two topological superconducting islands connected via a Josephson junction. The qubit is operated by electrostatic gates which control the coupling of two of the four Majorana zero

Comparative Insights Into the Degree of Conversion of a 3D‐Printed Photopolymer Occlusal Splint Resin Fabricated by Stereolithography and Masked Stereolithography Compared to Heat‐Polymerized Acrylics

open access: yesMacromolecular Materials and Engineering
The degree of conversion (DC) is a critical determinant of the biocompatibility and long‐term performance of occlusal splints. However, limited evidence exists on how emerging three‐dimensional printing technologies, particularly masked stereolithography

TOWARDS A FUTURISTIC EDUCATIONAL DEVELOPMENT IN NIGERIA [PDF]

open access: yes, 2008
Majority of the nations of the world were colonized and went through wars at various times, but had turned around their fortunes through economic and educational reforms. In Nigeria however, there had been series of educational reforms from: 7/6-5-4 to

Physico-Mechanical Properties and Bonding Performance of Graphene-Added Orthodontic Adhesives

open access: yesJournal of Functional Biomaterials
This study aimed to assess the key physico-mechanical properties and bonding performance of orthodontic adhesives with graphene addition for bonding a fixed retainer. Transbond LR (3M) and Transbond LV (3M) with no graphene were set as the control groups.

The role of tropical forests in supporting biodiversity and hydrological integrity: a synoptic overview [PDF]

open access: yes
Conservation of high-biodiversity tropical forests is sometimes justified on the basis of assumed hydrological benefits - in particular, the reduction of flooding hazards for downstream floodplain populations.
