Reproductive boll weevil populations are typically identified by the presence of a frass seal and protuberance at the oviposition site in cotton squares. However, despite the occurrence of other oviposition puncture seal types and their use in previous fecundity studies, the relationship of these respective puncture seal types and oviposition has not been clearly examined.

Introduction: Glass ionomer and polycarboxylate cement have different effects on the marginal seal, microleakage, pulp tissue stimulation, and gingival health. The purpose of this study was to assess the effect of these cement on the gingival health of primary molars restored with stainless steel crowns (SSC). Methods: A total number of 34 children were selecte...

Many types of noise can be present in an image. Registration becomes difficult when the concerned pattern contains a “seal noise.” In this paper, the seal noise appearing inherently in a seal image is introduced. The registration of seal images used widely in many commercial applications in Chinese society is presented. An effective approach using contour analysis for finding the principal orie...
