AGN dust tori at low and high luminosities
A cornerstone of AGN unification schemes is the presence of an optically and geometrically thick dust torus. It provides the obscuration to explain the difference between type 1 and type 2 AGN. We investigate the influence of the dust distribution on the Eddington limit of the torus. For smooth dust distributions, the Eddingtion limit on the dust alone is 5 orders of magnitudes below the limit ...
متن کاملReduced Wolf-Rayet Line Luminosities at Low Metallicity
New NTT/EMMI spectrophotometry of single WN2–5 stars in the Small and Large Magellanic Clouds are presented, from which He λ4686 line luminosities have been derived, and compared with observations of other Magellanic Cloud WolfRayet stars from the literature. SMC WN3–4 stars possess line luminosities which are a factor of 4 times lower than LMC counterparts, incorporating several binary SMC ...
متن کاملLooking at Globalization of English in the Context of Internationalism
The present study is an attempt to provide a current synopsis of World Englishes within globalized communities, as well as theoretical and applied feasibility of global linguistic features of English as an International Language (EIL). To do so, first, three main reactions against the spread of English by scholars around the world are discussed. Then, the possibility of describing and teaching ...
متن کاملReproductive enhancement in buffalo: looking at urinary pheromones and hormones
The success of conception in buffalo is greatly dependent on precise estrus detection and time of artificial insemination (AI). Various visual, behavioral, biochemical and gyneco-clinical parameters have been tracked closely and a cost-effective combinatorial model has been developed to detect estrus in buffaloes. Pheromones play pivotal roles in reproduction and behavior of mammals. Urine, an ...
متن کاملLooking at Full Looking Ahead
Haralick and Elliott's full looking ahead algorithm [4] was presented in the same article as forward checking, but is not as commonly used. We give experimental results which indicate that on some types of constraint satisfaction problems, full looking ahead outperforms forward checking. We also present three new looking ahead algorithms, all variations on full looking ahead, which were designe...
