ADAPTIVE DIVERGENCE AT THE MARGIN OF AN INVADED RANGE

Evolution, 2012
Invasive plant species threaten biological communities globally. However, relatively little is known about how evolutionary processes vary over the course of an invasion. To evaluate the importance of historical and adaptive drivers of range expansion, we compare the performance of North American populations of invasive Lonicera japonica from areas ...

How Could the Use of Crop Wild Relatives in Breeding Increase the Adaptation of Crops to Marginal Environments?

Frontiers in Plant Science, 2022
Alongside the use of fertilizer and chemical control of weeds, pests, and diseases modern breeding has been very successful in generating cultivars that have increased agricultural production several fold in favorable environments.

Influence of a proximal margin elevation technique on marginal adaptation of ceramic inlays [PDF]

Acta Odontologica Scandinavica, 2012
Evaluating the effect of a proximal margin elevation technique on marginal adaptation of ceramic inlays.Class II MOD-cavities were prepared in 40 human molars and randomly distributed to four groups (n = 10). In group EN (positive control) proximal margins were located in enamel, 1 mm above the cementoenamel junction, while 2 mm below in groups DE-1In,

Evaluation of adaptation of ceramic inlays using optical coherence tomography and replica technique

Brazilian Oral Research, 2018
Optical coherence tomography (OCT) has generally been used as a nondestructive technique to evaluate integrities of composite restorations. We investigated marginal and internal adaptations of ceramic inlay restorations with OCT and compared them to ...

Dynamic Distribution Adaptation Based Transfer Network for Cross Domain Bearing Fault Diagnosis

Chinese Journal of Mechanical Engineering, 2021
In machinery fault diagnosis, labeled data are always difficult or even impossible to obtain. Transfer learning can leverage related fault diagnosis knowledge from fully labeled source domain to enhance the fault diagnosis performance in sparsely labeled

The effect of composite resin preheating on marginal adaptation of class II restorations

Journal of Clinical and Experimental Dentistry, 2020
Background One of the problems with a high filler content composite resins is gap formation at restorative material–tooth interface. The present study investigated the effect of preheating composite resins on the formation of marginal gap in Cl II ...

Marginal adaptation of zirconia CAD-CAM copings with two cervical finish lines [PDF]

Journal of Dental Materials and Techniques, 2023
Introduction: Marginal adaptation is important for the long-term success of restorations. The finish line design can influence the marginal integrity. This study aimed to evaluate the effect of radial shoulder and deep chamfer finish line designs on the ...

Effect of Margin Design and Processing Steps on Marginal Adaptation of Captek Restorations [PDF]

ISRN Dentistry, 2011
This study examined the effect of four margin designs on marginal adaptation of Captek crowns during selected processing steps. Twenty-four Captek crowns were fabricated, six each of four margin designs: shoulder (Group A), chamfer (Group B), chamfer with bevel (Group C), and shoulder with bevel (Group D).

Heritage genetics for adaptation to marginal soils in barley [PDF]

Trends in Plant Science, 2023
Future crops need to be sustainable in the face of climate change. Modern barley varieties have been bred for high productivity and quality; however, they have suffered considerable genetic erosion, losing crucial genetic diversity. This renders modern cultivars vulnerable to climate change and stressful environments.

Comparative evaluation of effects of bleaching on color stability and marginal adaptation of discolored direct and indirect composite laminate veneers under in vivo conditions

The Journal of Indian Prosthodontic Society, 2015
Statement of Problem: Change in color and loss of marginal adaptation of tooth colored restorative materials is not acceptable. Bleaching is commonly used for treating discolored teeth.
