Stereolithographic (SLA) 3D printing of oral modified-release dosage forms.

International journal of pharmaceutics, 2016
The aim of this work was to evaluate the suitability of stereolithography (SLA) to fabricate drug-loaded tablets with modified-release characteristics. The SLA printer creates solid objects by using a laser beam to photopolymerise monomers.

A Phenomenological Study of Three University Students’ Experiences in Project Based Learning

JEELS (Journal of English Education and Linguistics Studies), 2016
Researchers in the past have explored practices of Project Based Learning (PBL) in various educational contexts. Nevertheless, previous studies that examine project-based learning in English as a Foreign Language (EFL) contexts are still limited in ...

Minimizing SLA violation and power consumption in Cloud data centers using adaptive energy-aware algorithms

Future generations computer systems, 2017
In this paper, we address the problem of reducing Cloud datacenter high energy consumption with minimal Service Level Agreement (SLA) violation. Although there are many energy-aware resource management solutions for Cloud datacenters, existing approaches

Can a sociolinguistic perspective of Second Language Acquisition solve ‘the longstanding human curiosity’ of learning languages? [PDF]

Training, Language and Culture, 2019
The present paper looks into SLA research which has been overwhelmed with multitude of competing theories, thus making it plausible that none of them alone can explain the complex issue to a satisfying extent.

Support‐Controlled Reaction Pathways via Dynamic Sulfur‐Mediated Interfaces for Selective Urea Electrolysis

Advanced Functional Materials, EarlyView.
Sulfur‐doped graphitized carbon nanofibers act as adaptive catalyst–support platforms, enabling dynamic sulfur‐mediated reconstruction and strong metal–support interactions. This unique behavior enhances catalyst stability and controls reaction pathways, achieving highly selective urea oxidation (∼92% N2) coupled with efficient hydrogen evolution ...
