This study offers initial research on Physically Interactive Technology (PIT). Findings of this research reveal how people made sense of PIT, how the ways people understand PIT reveal presence due to physical interaction, and how PIT challenges the definition of online interaction. Current and past literature on social presence theory and social cues theory provide a rationale for how “present”...

Aims and objectives: The aim of this in vitro study was to evaluate self-adhering composite Dyad flow (Kerr, USA) as a pit and fissure sealant. The objectives were to assess the degree of microleakage with self-adhering composite Dyad flow and that with Fissurit F as pit and fissure sealants and, to compare the same between these two materials. Materials and Methods: 20 premolars extracted for ...

OBJECTIVE Maiming and death due to dog bites are uncommon but preventable tragedies. We postulated that patients admitted to a level I trauma center with dog bites would have severe injuries and that the gravest injuries would be those caused by pit bulls. DESIGN We reviewed the medical records of patients admitted to our level I trauma center with dog bites during a 15-year period. We determ...

TITLE Antibacterial properties of fluoride releasing glass Ionomer cements (GICs) and pit and fissure sealants on Streptococcus mutans. BACKGROUND Occlusal pit and fissures are the most susceptible sites for dental caries. The clinical effectiveness of GICs and fissure sealants in preventing caries is well-documented, but there is some concern about bacteria left beneath sealants. OBJECTIVE...

The signals that guide the morphogenesis and differentiation of rat fetal gastric mucosa remain largely unknown. We have investigated the role of capsulin in pit/gland formation and epithelial cell differentiation in cultured stomach tissue. Embryonic day 16.5 (E 16.5) stomach tissue cultured for three days in the presence of 1 μM hydrocortisone underwent dramatic transformation, from undiffere...

Previous investigations showed that a single cavitation bubble collapse can cause more than one erosion pit (Philipp & Lauterborn [1]). But our preliminary study showed just the opposite - that in some cases a single cavitation pit can result from more than one cavitation event. The present study shows deeper investigation of this phenomenon. An investigation of the erosion effects of ultrasoni...

Three independent tracer experiments were conducted to quantify the through-flow of water from Herman Pit, an abandoned mercury (Hg) mine pit adjacent to Clear Lake, California, USA. The tracers used were Rhodamine-WT, sulfur hexafluoride, and a mixture of sulfur hexafluoride and neon-22. The tracers were injected into Herman Pit, a generally well-mixed water body of approximately 81,000 m2, an...

WHILE THE FUNCTIONS AND PURPOSES of a protein are invariant in biology, the view adopted by biologists often evolves with time sculpted by prevailing database and interpretations. PiT-2 along with its cousin PiT-1 (Na -coupled phosphate transporters of the SLC20 family) have been assigned varying roles and christened different aliases since their discovery. Although mammalian cells do not purpo...
