The binary system containing the pulsar PSR 1913+16 and ultra-violet and x-radiation from accreting magnetic white dwarfs
… Part II of the thesis treats ultra-violet and X-radiation from accreting magnetic white dwarfs. Matter from a companion star falling onto a white dwarf is shock-heated near the stellar surface and radiativaly cooled. I approximate the post-shock region by a uniform, geometrically thin slab and …

Proton deceleration near the surface of an accreting neutron star
… star accreting matter from a companion star, X-radiation is produced by the layer of hot, dense plasma that develops where the matter collides with the neutron star surface. The structure of this layer and the spectrum of the radiation produced there are determined by the way in which infalling …

Atomic short-range order determination in gold-25 atomic percent iron and nickel-12.5 atomic percent silicon: A synchrotron x-ray diffuse scattering study
… studied using wide-angle diffuse synchrotron x-radiation scattering at room temperature. Two heat-treatments were investigated; a 400$\sp\circ$C aging treatment for two days and a second at 440$\sp\circ$C for five days, both preceded by solution treatment in the single-phase field and …

X and UV radiation from accreting non-magnetic degenerate dwarfs
"X radiation from degenerate stars is produced by the impact of accreting matter with the stellar surface. The resulting X-ray and UV spectrum gives vital clues about the nature of the underlying star and the extreme conditions of temperature and magnetic field strength that may exist in the …

Metrologia dei campi di radiazioni di bassa energia
… quantities for ENEA’s realization of the X-radiation qualities L10-L35 of the ISO “Low Air Kerma rate” series (L), N10-N40 of the ISO “Narrow spectrum” series (N) and H10-H60 of the ISO “High Air-kerma rate” (H) series and two beams at 5 kV and 7.5 kV were determined by utilising X-ray …

Experimental and theoretical investigations of molecular ions by spectroscopy as well as ion mobility and mass spectrometry
… compounds in an APCI source based on soft x-radiation was investigated in a newly developed ionization chamber attached to the ion trap mass spectrometer. The major primary and secondary reactions could be characterized and explosive compound ions could be identified and assigned to the peaks …

Metastatic cell responses to anticancer therapy: The possible role of cancer stem cells
… of direct and bystander effect of ionising irradiation on the cancer cells glycosylation, EMT markers and invasiveness has not yet been investigated. Therefore, a study has been established to determine the direct effect, and if the progeny of cancer cells that survive a therapeutic dose of …

Defect production in alkali halide crystals by monochromatic x and UV radiation
… reactions of this impurity induced by irradiation into its ultraviolet absorption band were studied and luminescent emission from one of the hydroxyl dissociation products was observed for the first time.
