On the Ultraviolet Rays.

The killing effects of ultraviolet light and x-rays on free-living nematode, Rhabditidae tokai.

石井直 明,鈴 木堅之:東 海大学医学部分子生物学教室 伊勢原市望星台 〒259-11 Nematode/Radiation/Aging The life-shortening effects of ultraviolet light (UV) and X-rays were investigated with a strain of free-living nematode, Rhabditidae tokai . UV exhibited a significant life-shortening effect on adult worms, and it also inhibited growth of larvae , hatching of eggs and reproduc tion. Sensitivity to UV was decreased with increa...

survey on the rule of the due & hindering relying on the sheikh ansaris ideas

قاعده مقتضی و مانع در متون فقهی کم و بیش مستند احکام قرار گرفته و مورد مناقشه فقهاء و اصولیین می باشد و مشهور معتقند مقتضی و مانع، قاعده نیست بلکه یکی از مسائل ذیل استصحاب است لذا نگارنده بر آن شد تا پیرامون این قاعده پژوهش جامعی انجام دهد. به عقیده ما مقتضی دارای حیثیت مستقلی است و هر گاه می گوییم مقتضی احراز شد یعنی با ماهیت مستقل خودش محرز گشته و قطعا اقتضاء خود را خواهد داشت مانند نکاح که ...

SOFT X-RAYS AND EXTREME ULTRAVIOLET RADIATION Principles and Applications

Immunizing potential of vaccinia virus inactivated by ultraviolet rays

[1] In a precedent paper (1*), we have indicated that the vaccinia infection experiments of the rabbit skin can be inhibited by the intradermal injection of the equivalent virus inactivated by ultraviolet irradiation. [2] We have tried next, on one hand, to see if the complete virus is the sole inhibitory factor contained in the virulent materiel. [3] On the other hand, regarding to know if it ...

Soft X-rays and Extreme Ultraviolet Radiation: Principles and.

1.1 (a) Confirm that for a photon energy h ω, with corresponding wavelength λ in vacuum, the two are related by eV nm 1239.842 ⋅ = ⋅ λ ω h Values for physical constants are given in Appendix A, page 419. (b) What wavelength in nm corresponds to photons of energy 543.1 eV? (c) What wavelengths in vacuum are associated with the K and L-absorption edges of neon, chlorine, cobalt, and ruthenium? 1....
