OBJECTIVE The aim of this study was to evaluate the temperature change at various sites within the composite and on the pulpal side of dentin during polymerization of two composite increments. MATERIALS AND METHODS Class I cavities prepared in third molars were restored in two composite increments (n = 5). Temperatures were measured for 110 s using eight thermocouples: bottom center of cavity...

Conflicting results to identify the relationship between tooth loss and cancer risk. Therefore, a dose-response meta-analysis was performed to clarify and quantitative assessed the correlation between tooth loss and cancer risk. Up to March 2017, 25 observational epidemiological studies were included in current meta-analysis. Tooth loss was significantly associated with a higher risk of cancer....

Neutrino oscillations affect light-element synthesis through the -process in supernova explosions. The Li and B yields produced in a supernova explosion of a 16.2 M star model increase by factors of 1.9 and 1.3 in the case of the large mixing angle solution with a normal mass hierarchy and sin2 13k 2 ; 10 3 compared with those without the oscillations. In the case of an inverted mass hierarchy ...

A 38-year-old lady, gravida 4, attended antenatal check-up at 34 weeks of gestation, ultrasonography was done and the fetus noted to have an intraabdominal cystic mass. She had no significant past medical history, and previous antenatal follow up was uneventful. The mass was hyperechoic with well-defined margin. It measures 8.2cm x 7.7cm, and occupied nearly the entire fetal abdomen. Reassessme...

The L p-min increment t and L p-min increment ultrametric t problems are two popular optimization problems arising from distance methods for reconstructing phyloge-netic trees. This paper gives the following results: 1. An O(n 2) approximation algorithm with ratio-3 for L 1-min increment t. 2. A ratio-O(n 1=p) approximation algorithm for L p-min increment ultrametric t. 3. The neighbor-joining ...

Environmental concerns have urged a search for eco-friendly refrigerants in the refrigeration industry to overcome ozone depletion and global warming problems. Therefore, current research emphasizes frictional pressure drop during flow boiling of environment-friendly (GWP<150), isobutane, HFC-152a, HFO-1234yf were tested against commonly reported HFC-134a. The data presented here was collected ...

Propagation of the finite amplitude electromagnetic wave through partially spin-polarized degenerate plasmas leads to an instability. This instability happens due interaction with small-frequency longitudinal spin-electron-acoustic waves. The strongest growth in high-density Fermi momentum close mec, where me is mass electron and c speed light. increase increment spin polarization found.

A liquid chromatography-tandem mass spectrometry (LC-MS/MS) method was developed for the detection and quantitation of karlotoxins in the selected reaction monitoring (SRM) mode. This novel method was based upon the analysis of purified karlotoxins (KcTx-1, KmTx-2, 44-oxo-KmTx-2, KmTx-5), one amphidinol (AM-18), and unpurified extracts of bulk cultures of the marine dinoflagellate Karlodinium v...

1. The rod-isolation technique of Aguilar & Stiles (1954) was used to obtain scotopic increment-threshold functions in the dark-adapted eye. Increment-threshold functions were obtained for background durations of 50 to 500 msec, but the onset of the background and increment fields was always simultaneous. In all conditions the duration of the increment field was 50 msec. 2. The pattern of resul...
