HegazyAbstractGamma radiation synthesis of Polyaniline/glycidyl methacrylate [P(ANI/GMA)] and Polyaniline/glycidyl methacrylate/Ag2O (P(ANI/GMA)-Ag2O were prepared by adding different concentrations of AgNO3 to the prepared Polyaniline/glycidyl methacrylate. The formation of the function groups of P(ANI/GMA) and P(ANI/GMA)-Ag2O nanocomposites have been investigated by FT-IR. The X-ray patterns of P(ANI/GMA)-Ag2O nanocomposites showed more than crystalline peaks proving the existence of Ag2O nanoparticles within the polymeric composite at 2θ = 27.7° and 32.3°. The surface morphology and the average particle size of the prepared P(ANI/GMA) and P(ANI/GMA)/Ag2O nanocomposites have been determined using Scan electron microscope (SEM) and Transmission electron microscope (TEM), respectively. The results indicate that the spherical form of Ag2O nanocomposites is predominant with average size 3.57, 5.7 and 10.3 nm for AgNO3 contents 0.1, 0.3 and 0.5%. The particle size measured by DLS was found to be 78.82 and 81.68 nm for P(ANI/GMA) and P(ANI/GMA)-Ag2O (0.3%), respectively. The electrical conductivity of P(ANI/GMA) not only increased by adding Ag2O but also by increasing Ag2O contents. The results showed that the electrical conductivity of P(ANI/GMA) increases from 1.343 x 10-3 to 0.181 x 10-2 S/cm for...

A Batavia hospital has submitted plans for a $7.8 million expansion, a re-do on a plan first announced two years ago. The United Memorial Medical Center project includes a 5,000-square-foot imaging department addition to house a new MRI, CT scanner, and additional X-Ray room plus a new morgue. It’s the first phase of a three-phase plan at the 131-bed hospital, which was initially submitted to the state Depart ment of Health this week in an $18 million proposal that went on to receive approvals…

CONCLUSIONS: In Romanian population, the MMC of mandibular first molars, when present, is commonly associated with a second distal canal, unlike the mandibular second molars where the occurrence of a MMC was associated with only one distal canal. When performing the preoperative evaluation, it has also to be considered the patient gender, since the maleāˆ•female ratio of MMC was 1:3 in mandibular first molars and 5:1 in mandibular second molars.

CONCLUSION: There is a good correlation between the clinical symptoms and lateralisation of hydropic changes on magnetic resonance imaging. Further refinements of imaging techniques and grading system will likely improve the diagnostic accuracy and clinical utilisation of hydrops magnetic resonance imaging.

ConclusionOur study estimated the number of stroke patients undergoing CTA for suspected LVO and those eligible for thrombectomy in relation to the population. Numbers were essentially the same throughout the week, and during office and on-call hours. Our data can be used to make adequate staffing plans.
