The effect of new non-cross resistant antitumor agents on the energy state of human erythrocytes
PublicationPrzebadano pochodne benzoperimidynowe i antrapirydonowe odnośnie ich wpływu na stan energetyczny ludzkich erytrocytów. Stwierdzono, że poziom nukleotydów jak i wartość AEC erytrocytów nie zmienił się w ciągu 24 h inkubacji z powyższymi związkami. Jest to wynik obiecujący w odniesieniu do ich zastosowania jako związków aktywnych w pokonywaniu oporności wielolekowej.

Effect of chemical composition on corrosion and wear behaviour of the composite Ni-Fe-Al2O3 coatings.
PublicationPrzedstawiono wyniki badań powłoki kompozytowej otrzymanej przez osadzanie katodowe galwaniczne w roztworze zawierającym sole niklu, żelaza oraz cząstki ceramiki Al2O3 o różnej wielkości i stężeniu. Wykazano, że charakterystyka ceramiki posiada wpływ na szybkość korozji i zużycia ściernego. W szczególności, zawartość ceramiki wpływa dodatnio na odporność na zużycie ścierne, ale nieco obniża odporność na zużycie korozyjne.

THE EFFECT OF BEECH WOOD DRYING ON HARDNESS IN THE LONGITUDINAL DIRECTION FROM THE BEGINNING TO THE REAR OF THE SAMPLES
PublicationThe objective of this study was to determine the hardness of beech wood samples (Fagus sylvatica L.) in the longitudinal direction from the beginning to the rear of the samples versus the method of drying. The warm air-steam mixture drying process and the modified airdrying process were used in the experiment. The warm air-steam mixture drying process, in comparison to the modified air-drying process, caused a reduction of the...

Effect of Maximal Breath Hold Apnea on Pial Artery Pulsation and Subarachnoid Width in Human
PublicationLittle is known about intracranial pressure (ICP)-cerebral hemodynamic interplay during maximal breath-hold apnea. A recently developed method based on near-infrared transillumination/backscattering sounding (NIR-T/BSS) noninvasively measures changes in pial artery pulsation (cc-TQ) as well as subarachnoid width (sas-TQ) in humans. Changes in sas-TQ correlate with ICP to a considerable extent, whereas cc-TQ reflects the functional...

Seismic pounding behavior of multi-story buildings in series considering the effect of infill panels
PublicationThe aim of the present paper is to study the influence of the infill panels on the seismic pounding response of adjacent structures in series. The contribution of the masonry infill has been simulated using equivalent diagonal compression struts. Steel frames have been assumed to have elastic-plastic behavior with 1% linear strain hardening. The dynamic contact analysis has been utilized where contact surface model (target and...

Effect of osmolytes of different type on DNA behavior in aqueous solution. Experimental and theoretical studies
PublicationOsmolytes, the small organic molecules accumulated in cells under environmental stress, can modulate the stability of biopolymers such as proteins and DNA. In spite of many years of research, there is no established molecular mechanism of the influence of osmolytes on DNA structure. Here, we used two model osmolytes that denature (urea) or stabilize (trimethylglycine, TMG) proteins to study their effect on DNA in aqueous solutions...
