Temporal dynamics of co‐inoculation of Leptosphaeria maculans and Leptosphaeria biglobosa determine interspecific competition and disease development on oilseed rape

Pest Management Science, EarlyView.
This study provides evidence that the timing of co‐inoculation of Leptosphaeria maculans and Leptosphaeria biglobosa determine the outcome of interspecific competition and disease development on their host oilseed rape. Abstract BACKGROUND Phoma stem canker is one of the most economically damaging diseases of oilseed rape, caused by co‐existing fungal ...

Roughness Measurements at Small and Uneven Surfaces of Ceramic Foam Filters

Surface and Interface Analysis, EarlyView.
ABSTRACT This study investigated the possibility of roughness characterization of ceramic foam filters using a laser scanning microscope, examining the influence of magnification, measured area, cutoff wavelength (λc), measured roughness parameter, and position within the ceramic foam on the measured roughness data. Firstly, the effect of magnification

The effect of sterilization and disinfection on the physical-mechanical properties of preformed crowns

Journal of Indian Society of Pedodontics and Preventive Dentistry, 2021
Introduction: Different sizes of crowns may be tried on children since there is no universal crown size because of distinctions in tooth morphology from one child to other. During the process of trial and error, the crown gets contaminated which needs to

Residual Cement Excess of Composite Versus Glass Ionomer Cement in Implant‐Supported Single Crowns After Different Intraoral Exposure Times—A Randomized Controlled Clinical Trial

Clinical Oral Implants Research, EarlyView.
ABSTRACT Objective To evaluate the frequency and quantity of residual cement after cementation of monolithic zirconia crowns with glass ionomer or resin composite cement on customized ceramic abutments, following different intraoral retention times. The influence of margin location, quadrant and implant region was also assessed.
