considering the emergence of antibiotic resistance, scientists are interested in using new antimicrobial agents in the treatment of infectious diseases including infections of the enteric systems. lactic acid bacteria have the great potential to produce antimicrobial compounds that inhibit and control pathogenic bacteria. the aim of this study was to determine the anti-bacterial and anti-adhere...

in this research work, the effects of natural fibers such as date palm fiber (df) and jute fiber (jf) on bending properties of polypropylene (pp)/ ethylene–propylene–diene–monomer (epdm) thermoplastic elastomers are investigated. for this purpose, the date palm and jute fibers at five levels of fiber weight fractions (0, 5, 10, 20 and 30 wt. %) are utilized during composite fabrication. maleic ...

natural rubber/fiber composites were prepared in a laboratory mixer using new and waste short nylon fiber by a one-step mixing process. fiber loading and bonding agent effects on the microstructure and mechanical properties of the composites were studied. the cure characteristics of composites were investigated by using rheometer. cure and scorching times of the composites decreased while maxim...

Chitosan bears numerous properties, such as biocompatibility, biodegradability and non-toxicity making it suitable for use in different biomedical fields. Zinc (Zn) is required for fibroblasts proliferation and collagen synthesis as essential elements of wound healing. Its nanoparticles are well known for their capability to enhance wound healing by cell adhesion and migration improvement throu...

Cementing of the casing pipes inside the wellbore is considered as one of the most expensive and difficult operations during the well construction process. A low quality cementing job leads to further repair operations, which are usually costly and time-consuming to conduct. Polymer cements are being used for decades in the oil and gas industry due to their improved properties such as sedimenta...

different amounts of nanoclay were incorporated into the acrylic resin matrix at 0, 1, 3, and 5 wt.% loadings. the coatings were applied on low carbon steel plates. optical microscopy, sedimentation test, transmission electron microscopy, and x-ray diffraction were employed to investigate the dispersion of nanoclay in matrix. the corrosion resistance of coatings was evaluated by electrochemical...

Background and Aims: Uropathogenic E.coli is one of the most known causes of urinary tract infections, which may lead to a high rate of morbidity and mortality in high risk patients. In this regard, the virulence factors such as bacterial adhesion molecules have a critical role. The current study was intended to determine the molecular properties of adhesion genes in Uropathogenic E.coli strain...
