Germ line transformation of white- Drosophila embryos with P-element vectors containing white expression cassettes results in flies with different eye color phenotypes due to position effects at the sites of transgene insertion. These position effects can be cured by specific DNA elements, such as the Drosophila scs and scs' elements, that have insulator activity in vivo. We have used this syst...

WD1704+481 is a visual binary in which both components are white dwarfs. We present spectra of the Hα line of both stars which show that one component (WD1704+481.2 = Sanduleak B = GR577) is a close binary with two white dwarf components. Thus, WD1704+481 is the first known triple degenerate star. From radial velocity measurements of the close binary we find an orbital period of 0.1448d, a mass...

We present new results of a survey for weak magnetic fields among DA white dwarfs with inclusion of some brighter hot subdwarf stars. We have detected variable circular polarization in the Hα line of the hot subdwarf star Feige 34 (SP: sdO). From these data, we estimate that the longitudinal magnetic field of this star varies from −1.1 ± 3.2 kG to +9.6 ± 2.6 kG, with a mean of about +5 kG and a...

White (Lohmann LSL) and Brown (ATAK-S) laying hens, were reared under organic and conventional cage rearing systems, and the effects of the rearing system on performance parameters, egg production, egg characteristics, and immune response were investigated. For this purpose, a total of 832 laying hens of two commercial hybrids, i.e., 416 white (Lohmann LSL) and 416 Brown (ATAK-S) layers, were u...

The Ural type of the domestic Black-and-White mottled breed cattle features high rates milk productivity, good suitability for industrial milking technology, but productive longevity is 2.4–2.6 lactations only, although in herds there are livestock cows with a up to 10 lactations. decline associated deterioration reproductive qualities cows. In result research it was found that most resistant l...

We have developed a lane change aid system (LCAS), which detects vehicles behind in adjacent lanes with multi-line CCD sensors and informs the driver of vehicle location with a head-up display (HUD). Instead of processing camera images directly, a multi-line CCD sensor contains the pairs of line CCDs and measures two-dimensional distance distribution by comparing the brightness on line CCDs. To...
