چکیده
Za model vodiËa i feromagnetske ploËe napravljen je 3D proraËun magnetskog polja pomoÊu integralnih jednadæbi za kvazistatiËki sluËaj. Usporeeni rezultati proraËuna i mjerenja dobro se slaæu. Pristup preko integralnih jednadæbi pokazuje se vrlo efi kasnim u prostoru u kojem se traæi polje daleko od izvora i u kojem nema puno razliËitih feromagnetskih materijala. Pri tome se pretpostavlja da su vodljivost i permeabilnost feromagnetskog materijala konstantni. Takoer je prikazan utjecaj feromagnetskog materijala na magnetsko polja vodiËa. The 3D calculation of the magnetic fi eld around a model of a current carrying conductor and ferromagnetic plate has been performed by means of integral equations in the quasistatic case. There is good agreement between the calculated and measured results. The integral equation approach is very effective in a space in which a fi eld distant from the source is calculated and there are not many different types of ferromagnetic materials. The conductivity and permeability of the ferromagnetic materials are assumed to be constant. Furthermore, the infl uence of the ferromagnetic materials on the magnetic fi eld of a conductor is shown. KljuËne rijeËi: 3D proraËun, feromagnetski materijal, integralne jednadæbe, kvazistatiËko magnetsko polje

In critically ill patients, catheter-related bloodstream infections (CRBSIs) are associated with increased mortality, length of stay in the ICU and extra costs. The relative risk of infection can be best determined by analyzing rates of catheter-related bloodstream infections per 1000 catheter-days. Coagulase-negative staphylococci, Staphylococcus aureus and Candida spp are the pathogens found ...
