... Information about a variety of different calendars for different cultures (e.g., Christian, Jewish, Muslim, Chinese, Hindu etc.) ... In addition, the Chinese had two different ways of interpreting and observing celestial events. One way the Chinese used astronomy was known as lifa; it was a discipline that aimed to understand the regularities and the predictable events in the celestial system through careful, observations, measurements and records. ... back to Teachers' Newsletter Main Page ...

The cosmic microwave background, shown at left in this illustration, is a flash of light that occurred when the young universe cooled enough for electrons and protons to form the first atoms. ... The universe then went dark for hundreds of millions of years until the first stars shone and the first black holes began accreting gas. A portion of the infrared and X-ray signals from these sources is preserved in the cosmic infrared background (CIB) and its X-ray equivalent, the CXB. ...

Mikhail TAMM (LPTMS, Paris-11 Orsay): "Clover-leaf structures in associating polymers: a toy model for RNA folding . The clover-leaf structures under discussion are defined as follows. The polymer is supposed to bear numerous sticky centers along the chain, these centers being capable of forming thermoreversible bonds with each other. ... Now, we say that some given structure belongs to the clover-leaf type if the archs on the corresponding diagram do not intersect each other. ...

The first series of images refers to NGC 1672, a barred spiral. We present a gray scale V-band image to show the overall morphology, followed by an intensity map in H-alpha which shows how the H II regions are distributed, followed by the velocity map. ... Different colors refer to different velocities as the galaxy is rotating. ... The following image is an H-alpha intensity map of the spiral galaxy NGC 1292. ... This next image is an H-alpha intensity map of the spiral galaxy NGC 1406. ...

Underdetermined sets is a new type of data structures (terms) developed in Actor Prolog . ... The point is that an underdetermined set can include some indefinite rest (a tail) like a list in usual Prolog . At the same time, the order of elements of an underdetermined set can be arbitrary one and it does not affect results of unification of underdetermined sets. Moreover, Actor Prolog guarantees that a rest of an underdetermined set never contains elements that are explicitly given in the set. ...

RTT150 . ... This search system is designed for generating the necessary information on series of pointings (observations of each source consist of sets of exposures with different filters and sometimes with different exposure times) for observed sources. Search results appear at the separate page as a table with the following data: . DATE - real (not evening!) observations date (in YYYY-MM-DD format); . ... Bin - minimal CCD binning mode (may vary during the observations); . ...
