Staphylococcus aureus is a major problem in both the clinical setting and within the community. S. aureus can quickly develop resistance to a wide range of antibiotics through a number of different mechanisms, of which, using transporters located in the cell membrane to pump antibiotics out of the cell is the most serious concern.

A highly effective adsorbent comprised of the Graphene membrane was created using the sonification method in this study. For all we know, the resulting Graphene membrane was employed as an adsorbent for transformer oil purification for the first time. The quality of the treated oil was evaluated through several factors, such as acid number TAN(mg KOH/g), color, breakdown voltage, and viscosity.

Acoustic properties of foams, such as macroscopic transports and sound absorption, are significantly influenced by their local morphology. The present paper develops a polynomial chaos expansion (PCE)-based surrogate model for characterizing the microstructure-properties relationships of acoustic monodisperse foams.

The potential for progressive collapse of RC buildings can be estimated by column loss scenarios. The loss of either internal or external penultimate columns is among the most critical scenarios since the beam-slab substructures associated with the removed column becomes laterally unrestrained with two discontinuous edges.

In this study, we synthesized hydroxyapatite (HA) on polyvinyl alcohol/TiO2 (PVA/TiO2) in which TiO2 was prepared by the sol-gel method. HA was formed by immersing the membrane in the simulated body fluid (SBF) solution. We improved the mechanical strength of the membranes by adding glutaraldehyde (GA) combining with heat treatment to cross-link the polymer network.

In the present study, we have made an attempt to prepare complexed PVA-PVP-KNO3-BaTiO3 blend composite polymer electrolyte membranes composed of potassium nitrate (KNO3) as salt and BaTiO3 of various concentrations as filler and studied their properties. The advantages of addition the fillers are the increase in ionic conductivity at room temperatures and the improvement of the stability at the interface with electrodes.

This work demonstrated the potential of US for mitigating membrane fouling. However, the integration of the US transducers within the membrane system will be a major challenge for the application of US in membrane cleaning. It is more appropriate that US is used as pre-treatment to the membrane system, the transducers can be placed prior to the coagulant feed line. Further work on the determination of the detailed mechanisms associated with enhancing coagulation would enable optimisation of the system with regard to process, cost and energy efficiency.

The research herein builds on the work of Rojek (2003) and further investigates the bioremediation of NOM wastes. The aim of this research was to evaluate the effectiveness of selected white-rot fungi and yeast for the biodegradative removal of concentrated NOM from solution. The effectiveness of the white-rot fungus P. chrysosporium ATCC 34541 for the biological degradation of different batches of MIEXTM NOM concentrate and the effects of different characteristics of the NOM on the process and thus the resistance of the NOM to microbial removal were investigated.
