Quality, safety and efficiency in practice: Risk assessment and standardisation of anesthesia equipment and supplies in operating theaters of high-volume tertiary-care academic medical center
(
American University of Beirut
, 2019 , Article)
Background: Operating theatres (OTs) are valuable and costly resources that need to be appropriately designed and stocked for efficient, quality and safe patient care. We assessed the logistic inefficiency including the ...
Effect of calcium nitrate healing microcapsules on concrete strength and air permeability
(
ICE Publishing
, 2019 , Article)
This study investigates the compressive and flexural strengths, flexural modulus and air permeability of concrete samples containing 0.75% by cement weight of modified calcium nitrate self-healing microcapsules. The ...
Role of TiO2 and carbon nanotubes on polyethylene, and effect of accelerated weathering on photo oxidation and mechanical properties
(
John Wiley and Sons Ltd
, 2019 , Article)
In this work, LLDPE-based composite films were prepared by melt mixing followed by compression molding to investigate the role of titanium oxide nanoparticles (TONPs) and/or multiwalled carbon nanotubes (CNTs) on the ...
Resistive room temperature LPG sensor based on a graphene/CdO nanocomposite
(
Springer-Verlag Wien
, 2019 , Article)
The authors decribe an ultra-sensitive, room temperature, flexible transparent LPG sensor based on the use of a CdO/graphene nanocomposite. The graphene prevents the accumulation of CdO, enhances the surface area, and acts ...
Confined Interfacial Monomicelle Assembly for Precisely Controlled Coating of Single-Layered Titania Mesopores
(
Cell Press
, 2019 , Article)
The development of core-shell structures has been in great demand recently owing to their integrated functionalities. However, the progress in reliable coating of porous semiconductors remains unproductive. Here, we have ...
Industrial effluent treatment with immersed MBRs: Treatability and cost
(
IWA Publishing
, 2019 , Article)
A comprehensive OPEX analysis for both municipal and industrial wastewaters has been conducted encompassing energy, critical component (membrane) replacement, chemicals consumption, waste disposal and labour. The analysis ...
Vibrations Serviceability of a Medical Facility Floor for Sensitive Equipment Replacement: Evaluation with Sparse in Situ Data
(
American Society of Civil Engineers (ASCE)
, 2019 , Article)
Vibrations serviceability of building floors has been a growing concern over the years. For steel-framed systems, vibrations serviceability checks often govern the structural design. When the floor is carrying vibration-sensitive ...
Recycling of Date Pits Into a Green Adsorbent for Removal of Heavy Metals: A Fractional Factorial Design-Based Approach
(
Frontiers Media S.A.
, 2019 , Article)
Date pits (DPs) have been recycled into a low-cost adsorbent for removing of selected heavy metals (HMs) from artificially contaminated aqueous solutions. Adsorption of targeted HMs, both by raw date pits (RDP) and burnt ...
Production of sensitive gas sensors using CuO/SnO2 nanoparticles
(
Springer Verlag
, 2019 , Article)
Metal oxide nanoparticles, such as CuO and SnO2, are outstanding systems for H2S gas sensing in air. In this work, those nanoparticles were deposited with different mixing percentages on substrates to form percolating ...
Polyzwitterionic Hydrogels in Engines Based on the Antipolyelectrolyte Effect and Driven by the Salinity Gradient
(
American Chemical Society
, 2019 , Article)
In this paper, we propose and investigate an original approach to energy conversion based on polyzwitterionic hydrogels, which exhibit an antipolyelectrolyte effect that enables them to swell in salt water and shrink in ...
