in order to investigate factors affecting on seed germinating of london rocket (sisymbrium irio), lab experiments were set up in 2011 at the payamenoor university, mashhad, khorasan razavi province. effect of different concentrations of gibberellic acid (ga3) and cytokinin, wet and dry prechilling duration, hydrogen peroxide duration, ethanol, salt and osmotic stress and burial depth on seed ge...

This article explores the impact of the professional culture of rocket engineering in Stalin’s Soviet Union on the engineering and organizational practices of the space program during the Khrushchev era. The Stalinist legacy and the dual military / civilian character of rocket engineers’ work profoundly affected the identity of this elite part of Soviet technical intelligentsia. Focusing on suc...

A new tuberculosis vaccine is urgently needed. Prime-boost strategies are considered very promising and the inclusion of BCG is highly desirable. In this investigation, we tested the protective efficacy of BCG delivered in the neonatal period followed by boosters in the adult phase with a DNA vaccine containing the hsp65 gene from Mycobacterium leprae (pVAXhsp65). Immune responses were characte...

The tetanusanddiphtheriavaccinationprogramme inFinlandhasbeen running for50years.Afterprimary doses, tetanusboostershavebeenoffered tomen inmilitary service anddecennial boosters recommended for all through the adult life. For 30 years a diphtheria booster was only offered to men in the military service. Not until 1989 diphtheria–tetanus (dT) and diphtheria (d) booster vaccines for adolescence ...

We propose a robust and efficient algorithm called ROCKET for clustering large-scale transaction databases. ROCKET is a divisive hierarchical algorithm that makes the most of recent hardware architecture. ROCKET handles the cases with the small and the large number of similar transaction pairs separately and efficiently. Through experiments, we show that ROCKET achieves high-quality clustering ...

There is one way to explore space by using the launch vehicles, which known as rockets, and it can carry useful load named simply payload of satelite from Earth into Space. In this study, performance predictions multi rocket motors are discussed compared with single motor same amount propellant used for travel. article in serial or tandem staging schemes, boosting stage usually largest, second ...

Yellow rocket, Barbarea vulgaris (R. Br.) variety arcuata, was evaluated as a trap crop for diamondback moth, Plutella xylostella (L.) (Lepidoptera: Plutellidae), in cabbage, Brassica oleracea L. variety capitata, in 2003 and 2004. In 2003, the numbers of P. xylostella larvae found in field plots of cabbage alone were 5.2-11.3 times higher than those on cabbage plants in plots that included cab...
