An observational synthesis of the Taurid meteor complex
نویسندگان
چکیده
We provide an overview of the observational properties four major Taurid showers, namely Northern and Southern Taurids (#017 NTA #002 STA), Beta (#173 BTA) Zeta Perseids (#172 ZPE). Analysing more than two decades meteor observations from visual, optical radar measurements we present average activity, annual variations in strength, radiant drift orbital as a function solar longitude particle size. The showers are detected over several weeks spring autumn, but their activity level is generally low (less 15 visual meteors per hour). find STA to be predominant while its twin ZPE dominates BTA spring. Due long duration, position each shower's elements variable with time. Optical have previously recorded enhanced increased fireball rates caused by return swarm meteoroids trapped 7:2 mean motion resonance Jupiter. However, no presence data, suggesting that small removed faster fireball-producing meteoroids. also enriched smaller particles early period. differences identify our analysis between at different sizes strong constraints future dynamical modelling Meteoroid Complex.

The Relationship Between Gingival Biotypes and Dentopapillary Complex: An Observational Study
Background and Aim: Gingival biotype is a principal component in restorative and implant procedures, especially in the aesthetic region. Immediate determination of the gingival biotype by the clinician could lead to a more successful outcome, especially during implant placement in the aesthetic zone. The aim of this study was to investigate a possible relationship between gingival biotypes and ...

heteropoly acids (hpa) and their salts have advantages as catalysts which make them both economically and environmentally attractive, strong br?nsted acidity, exhibiting fast reversible multi-electron redox transformations under rather mild conditions, very high solubility in polar solvents, fairly high thermal stability in the solid states, and efficient oxidizing ability, so that they are imp...
