چکیده
insemination by artificial or natural means, thereby minimizing the amount of error introduced in experimental work by the use of females in unknown physiological condition. In critical experiments by using for an indicator a vasectomized male, homozygous for one color factor, and for the later insemination sperm from a male homozygous for another color factor, one will have a definite breeding test showing whether or not, by any accident, the vasectomized male was able to transfer sperm to the female.

ساخت و تحلیل فهرست ستارهای از کهکشان M33
In this study, 1200 images and catalogues of M33 spiral galaxy taken by WFCAM camera at UKIRT telescope in J, H and K bands. Cross correlation methods were employed to identify stars in overlapping regions from among images taken in different dates. Careful astrometric and photometric analysis was made to calibrate stellar positions and magnitudes using their 2MASS near infra red survey. The fi...
متن کاملAperture Photometry of Saturated Star Images from Digitised Photographic Plates
Saturated stellar images on digitised photographic plates are many times greater in area than the ‘seeing disk’ seen in unsaturated CCD images. Indeed the flux profile of a bright star can be traced out for several degrees from the star’s centre. The radius of the saturated stellar image can often be directly related to the magnitude of the star, a fact well known and exploited in iris photomet...
متن کاملRevised Magnitudes and Color Indices of the Planets.
In connection with the preceding investigation relating to the photovisual magnitudes of the stars, photovisual and photographic magnitudes of the brighter planets have been determined by out-of-focus methods. These observations were made with the view of obtaining better values of color index. The detailed discussion will appear soon in Harvard Annals, 85, No. 4. The number of plates taken for...
متن کاملPhotometric variability of LBV - candidate stars and Hubble - Sandage variables A , B , C and 2 in M 33
We present the photometric history of some Luminous Blue Variable candidate stars in M 33. The search for outbursts was made in photographic plates taken in the B band of the galaxy M 33 and cover an eight year period, 1982–1990. Twenty five plates, separated into seven groups, have been used. CCD UBV magnitudes of the star UIT003 are presented also. Only one (of 12) of the LBV candidates (UIT0...
متن کاملStarcounts Redivivus. IV. Density Laws Through Photometric Parallaxes
In an effort to more precisely define the spatial distribution of Galactic field stars, we present an analysis of the photometric parallaxes of stars in seven Kapteyn Selected Areas. Our photometry database covers ∼ 14.9 square degrees and contain over 130,000 stars, of which approximately 70,000 are in a color range (0.4 ≤ R − I ≤ 1.5) for which relatively unambiguous photometric parallaxes ca...
