In this paper, a new high ... -
Host specificity of pseudomonas aeruginosa isolates from patients with cystic fibrosis and patients from different clinical backgrounds.
( European Respiratory Society: ERJ , 2014 , Article)Background: Pseudomonas aeruginosa is one of the primary pathogens being isolated more frequently in cystic fibrosis (CF) and exhibits innate resistant to a wide range of antibiotics. Purpose: To determine whether the ... -
Insights into the interaction between mineral formation and heavy metals immobilization, mediated by Virgibacillus exopolymeric substances
( Elsevier , 2024 , Article)Heavy metal pollution poses significant risks to both the environment and human health due to their toxicity, long residence times, and their ability to bioaccumulate and bio magnify across the food chain. To address this ... -
Multi-module high voltage pulse generator based on DC-DC boost converter and CDVMs for drinking water purification
( Institute of Electrical and Electronics Engineers Inc. , 2016 , Conference Paper)High pulsed electric field (PEF) can be used effectively in drinking water purification, by applying it across the water sample to be treated. Application of sufficient high PEF guarantees killing of harmful germs and ... -
Novel approach to study the diversity of soil microbial communities in Qatar
( Qatar University Press , 2020 , Poster)A broad diversity of microorganisms can be found in soil, where they are essential for nutrient cycling and energy transfer. Recent high-throughput sequencing methods have greatly advanced our knowledge about how soil, ... -
A preliminary study on microbial air contamination in select schools in Doha, Qatar
( Springer Nature , 2021 , Article)Available data of the indoor airborne culturable bacteria and fungi at schools’ environments is very limited in the peninsula of Qatar. This study aims to determine the microbial load in indoor and outdoor air at three ... -
