Anticipating new spectroscopic studies of quasar companions, we calculate expected emission line spectra for the companion galaxies. Under the assumption of isotropic photoionizing radiation, we predict equivalent widths for Hα, Hβ, [O iii] λ5007, [O ii] λ3727, [Ne iii] λ3869, and Mg ii λ2798 lines. We consider 6 quasars, two of which (PKS 213514 and PKS 2349-014) have very close companions wit...

Bargaining with reading habit is no need. Reading is not kind of something sold that you can take or not. It is a thing that will change your life to life better. It is the thing that will give you many things around the world and this universe, in the real world and here after. As what will be given by this the early history of data networks, how can you bargain with the thing that has many be...

Can automatically generated questions scaffold reading comprehension? We automated three kinds of multiple-choice questions in children’s assisted reading: 1. Whquestions: ask a generically worded What/Where/When question. 2. Sentence prediction: ask which of three sentences belongs next. 3. Cloze: ask which of four words best fills in a blank in the next sentence. A within-subject experiment i...

We present results of the CFHT adaptive optics (AO) search for companions of a homogeneous group of contact binary stars, as a contribution of our attempts to prove a hypothesis that these binaries require a third star to become so close as observed. The data were obtained on two nights in 1998 and two nights in 2005. In addition to companions directly discovered at separations of 1 − 10 separa...

Self-gravitating protostellar discs are unstable to fragmentation if the gas can cool on a time scale that is short compared to the orbital period. We use a combination of hydrodynamic simulations and N-body orbit integrations to study the long term evolution of a fragmenting disc with an initial mass ratio to the star of M disc /M * = 0.1. For a disc which is initially unstable across a range ...

the holy prophet founded the recitation and inscription of the holy qur’an and also the education system of the qur'an with the purpose of better understanding of it. thus, according to occasions of revelation of the qur'an on the basis of seven letters, the holy prophet, not only, approved the recitations of the quran due to seven arabic accents and dialects of muslims; even, acclaim...

Context. Since 1999, we have been conducting a radial velocity survey of 179 K giants using the Coudé Auxiliary Telescope at UCO/Lick observatory. At present ∼20−100 measurements have been collected per star with a precision of 5 to 8 m s−1. Of the stars monitored, 145 (80%) show radial velocity (RV) variations at a level >20 m s−1, of which 43 exhibit significant periodicities. Aims. Our aim i...

Recent research has revealed beneficial post-partum, psychosocial effects on the mother following labour which was accompanied by supportive companions. Whether these effects are obtained as a result of having companionship during labour or because of specific personality characteristics of the companions provided is important and is explored in this paper. Although findings revealed few differ...

We present the results of a study of the late-type companions in hot subdwarf composite spectrum binaries. The exact nature of these late-type companions has been disputed in the literature — some argue that they are main sequence stars, and others have claimed they are subgiants. To determine the properties of the late-type companions, we first conducted a survey utilizing the Two Micron All S...
