The redshift of extragalactic nebulae
The important, lasting result of Fritz Zwicky’s early paper on extragalactic astrophysics, which is not mentioned in the abstract, is his conclusion, derived in Sect. 5, that the universe contains much more dark than luminous matter. This result is embedded in a review of what was known about “nebulae” and their redshift in 1933. The first methods to determine distances of galaxies and their di...
متن کاملExtragalactic Distances from Planetary Nebulae
The [O III] λ5007 planetary nebula luminosity function (PNLF) occupies an important place on the extragalactic distance ladder. Since it is the only method that is applicable to all the large galaxies of the Local Supercluster, it is uniquely useful for cross-checking results and linking the Population I and Population II distance scales. We review the physics underlying the method, demonstrate...
متن کاملthe relation between bilingualism and translation: a case study of turkish bilingual and persian monolingual translation students
translation studies have become an accepted academic subject and books, journals and doctoral dissertations appear faster than one can read them all (bassnet and lefevere, 1990). but this field also brought with itself so many other issues which needed to be investigated more, in the heart of which, issues like ideology, ethics, culture, bilingualism and multilingualism. it is reported that ove...

This study aimed to determine the association between Shift Work and chronic Fatigue among Educational Hospital Nurses. Materials and Methods: This cross-sectional study was carried out in Educational Hospital in Yazd. Using Stratified sampling technique, 200 ...
متن کاملApplication of Derivative Spectrophotometry to Determine the Relation Between Color Intensity and Dye Concentration of Madder
The Derivative Spectrophotometry usually improves resolution bands, eliminates the influence of background and provides more defined fingerprints than original spectra, hence enhancing the detectability of minor spectral features. In this work, different madder types were collected and applied for dyeing woolen yarns used in Persian carpet in conventional pre-mordanting and dyeing process with ...
