—The emerging mobile applications including contact-based forwarding and online worm containment have put a heavy burden on opportunistic social networks (OSNs), the first goal is to develop an effective model that can reveal the hidden, important social features underlying the OSNs. This problem is especially challenging because of the time-varying network topology. Traditional time expanded ...

Vocabulary learning is the foundation of second language learning. Many E-learning systems have been developed to help learners to learn vocabulary efficiently. Most of these systems employ Ebbinghaus Forgetting Curve to make the review schedule for learners. However, learners are different in learning ability and the review schedule based on Ebbinghaus Forgetting Curve may be not fit for every...

Background : The two most prevalent oral diseases are dental caries and periodontal disease. Humans of all ages suffer from caries, but schoolchildren represent the highest priority risk group. aim current study was to utilize dft/DMFT (DMFT Decayed missing filled teeth, dft decayed teeth) index assess prevalence among primary school-aged children in Poonamallee, Chennai. Methodology Before stu...

conclusions the dental health status of hiv-positive patients in this region was almost inappropriate. most social, behavioral, and medical factors had no influence on dental health; only a correlation between dental health, age, and duration of hiv involvement was observed. results the mean value of dmft index was 11.87 ± 8.08, where the mean values of decayed and missing teeth were 8.42 ± 5.4...

Managing for stand structural complexity in northern hardwood forests has been proposed as a method for promoting microhabitat characteristics important to eastern red-backed salamanders (Plethodon cinereus). We evaluated the effects of alternate, structure-based silvicultural systems on red-backed salamander populations at two research sites in northwestern Vermont. Treatments included two une...

The objective of this study was to investigate the influence of caregiver education level on children's dental caries mediated by both caregiver and child oral health behaviors. Participants were 423 low-income African American kindergarteners and their caregivers who were part of a school-based randomized clinical trial. Path analysis tested the hypothesis that caregiver education level affect...

BACKGROUND The aim of this study was to evaluate the effect of fluoride varnish on enamel caries progression in the primary dentition. METHODS One hundred forty-two children in Head Start schools (3 to 5 years old) were randomized into the varnish and control groups. Children in the varnish group received fluoride varnish (Duraphat, Colgate-Palmolive Co.) at baseline and after four months, an...

AIM The aim of this study was to compare the survival of composite resin restorations retained by glass fiber posts or reversed-orientated (upside-down) metal posts in severely decayed primary anterior teeth after 6, 12, and 18 months. MATERIALS AND METHODS A total of forty-four 3- to 5-year-old children with bilateral severely decayed primary maxillary canines were included. Patients were tr...

Abstract It is important for civil engineering applications to investigate resistance wood decay in aqueous environments. DNA from microorganisms inhabiting logs (groynes) that had been used about 15 years as a water control system prevent riverbank erosion was extracted and the microbial community structure examined. specimens four sections, above under water, ground bottom parts of were pulle...
