A deficiency of most current drug products for treatment of acute conditions is slow onset of action. A promising means of accelerating drug action is through rapid systemic drug administration via deep lung inhalation. The speed of pulmonary drug absorption depends on the site of aerosol deposition within the lung and the dissolution rate and drug content of the deposited particles. Alveolar d...

We investigate the nature of the physical structures giving rise to damped Lyα absorption systems (DLAS) at high redshift. In particular, we examine the suggestion that rapidly rotating large disks are the only viable explanation for the characteristic observed asymmetric profiles of low ionization absorption lines. Using hydrodynamic simulations of galaxy formation in a cosmological context we...

Virtual worlds (VWs) are media-rich cognitively engaging technologies that geographically dispersed organizations can use as a cost effective workplace collaboration tool. Using an information processing decision making perspective and building on unique characteristics of VWs, this paper proposes a nomological net for adaptive use intention (AUI) of VWs for workplace collaborations. AUI implie...

Luca Quaroni,* Katarzyna Pogoda, Joanna-Wiltowska Zuber, Wojciech Kwiatek Department of Experimental Physics of Complex Systems, Institute of Nuclear Physics, Polish Academy of Sciences, PL-31342, Kraków, Poland Abstract Atomic Force Microscopy – Infrared (AFM-IR) spectroscopy allows spectroscopic studies in the ...

The paper deals with the actual topic of mechanical properties 3D prints made from polymer material rPET-G and its changes. Using this in additive technology has great potential automotive industry. research evaluates five different post-processing modifications (recycled polyethylene terephthalate-glycol) produced by Fused Filament Fabrication technology. included chemical smoothing samples us...

Differential absorption lidar (DIAL) remote sensing is a promising technology for atmospheric CO2 detection. However, stringent wavelength accuracy and stability are required in DIAL system. Accurate on-line wavelength calibration is a crucial procedure for retrieving atmospheric CO2 concentration using the DIAL, particularly when pulsed lasers are adopted in the system. Large fluctuations in t...

Superconducting nanowire single photon detectors are rapidly emerging as a key infrared photon-counting technology. Two front-side-coupled silver dipole nanoantennas, simulated to have resonances at 1480 and 1525 nm, were fabricated in a two-step process. An enhancement of 50 to 130% in the system detection efficiency was observed when illuminating the antennas. This offers a pathway to increas...

We participated in the Coastal Benthic Optical Properties (CoBOP) experiment at Lee Stocking Island, the Bahamas, from 19 to 31 may, 1998. Our approach is to use the diver operated spectral absorption and attenuation meter (ac-9) developed by us in collaboration with Western Environmental Technology Laboratories (WET Labs). This device was used to measure these coefficients on small scales with...

All authors from AGH University of Science and Technology, Faculty of Foundry Engineering, Krakow, Poland The subject of the paper is the determination of the infl uence of the colloidal nanoparticles of zinc oxide on the structure of sodium water glass. Nanoparticles of zinc oxide in ethanol solvent were introduced into the water glass. The modifi cation and structural changes were determined ...

We report a new method for introducing metal atoms into silicon wafers, using negligible thermal budget. Molecular thin films are irradiated with ultra-violet light releasing metal species into the semiconductor substrate. Secondary ion mass spectrometry and x-ray absorption spectroscopy show that Mn is incorporated into Si as an interstitial dopant. We propose that our method can form the basi...
