BACKGROUND: Solutions of iodine contrast media (CM) used for selective coronary arteriography (CA) should have minimal propensity to cause ventricular fibrillation (VF). Commonly used CM for CA are nonionic monomers or dimers. PURPOSE: To compare VF propensity of ready-to-use solutions of one nonionic dimer, iodixanol, and five nonionic monomers, iobitridol, iopamidol, iomeprol, iopromide, and iov

The dynamical theory of X-ray spectra due to Nozieres and De Dominicis (ND, 1969) is evaluated here numerically for numerous model systems including cases where the core-hole potential possesses a bound state. It is shown that the resulting emission spectra obey the final-state rule rather accurately. An approximate but analytical derivation of this rule is given which provides insight into the me

The dysfunction of misplaced or dislodged endovascular endoprostheses, may be a serious complication, and endovascular removal may be attempted in some cases.

Optical absorption spectroscopy is a widely used analytical tool for constituent analysis in many applications. According to the Beer-Lambert law, the transmitted light intensity through a homogeneous medium is an exponential function of the product of the concentration, the total pathlength, and the absorption cross-section of the absorbing substance. By studying the intensity loss at the unique

Popular Abstract in Swedish Denna avhandlings inriktar sig i huvudsak mot utveckling och tillämpning av två nyligen framtagna optiska tekniker för förbränningsstudier. Dessa tekniker kallas mid-infrared polarisationsspektroskopi (IRPS) samt degenererad fyrvågsmixning (IR-DFWM), vilka båda är baserade på infrarött ljus med en våglängd runt 3 mikrometer, samt att teknikernas signalrespons är ickelinThe work reported in this thesis involved the development and application of two novel infrared non-linear laser techniques, namely mid-infrared polarization spectroscopy (IRPS) and mid-infrared degenerate four-wave mixing (IR-DFWM) to combustion diagnostics. These two techniques meet the needs of species concentration detection in combustion environments, especially for those species lacking acce

In a longitudinal study of 297 palliative care patients, 280 patients were followed from inclusion to death. Characteristics and health-related quality of life (HRQL) of the participants and those who later dropped out were compared at inclusion, and 3 and 2 months before their death. At inclusion, the dropouts were older (P = 0.001), had reduced Karnofsky performance score (P < 0.001), received m

Given an electronic wave function, generated by the MCHF program (LS format) or the MCHF_CI program (LSJ format), this program computes the hyperfine interaction constants, A(J) and B(J). In strong experimental magnetic fields, the splitting is also affected by the off-diagonal hyperfine constants A(J,J-1), B(J,J-1), and B(J,J-2) and these are computed as well, depending on the input data.

In our daily work at Certec, we often touch upon legal and ethical issues. This is mostly a good thing – it is important that an organization whose work is closely related to individuals carries on a discussion of ethics and constantly raises questions concerning issues that may be regulated by law. In our discussions, not only do we ask ourselves whether a particular action would be unlawful or u

The PHANToM is an invention from MIT, Massachusetts Institute of Technology, which enables tactile communication between a human and a computer. The PHANToM is developed as a general haptic interface. At CERTEC, Center of Rehabilitation Engineering, in Lu
