Percutaneous photoacoustic debulking of infra-inguinal atherosclerotic disease- early European experience with a novel, solid-state, pulsed -wave, ultraviolet 355 nm laser.

The broad spectrum of clinical manifestations caused by peripheral arterial disease [PAD] and the morphologic heterogeneity of associated atherosclerotic lesions present a considerable management challenge. Endovascular interventions are recognized an effective treatment for PAD. Within this revascularization strategy the role of atherectomy debulking modalities continue to evolve.

Possibility of brewery wastes application to soil as an organic improver of biological and chemical properties.

Soil degradation, marked by declining organic matter, threatens global food security. The impact of brewer's spent yeast (BSY) on clay and sand was analysed at varying application rates to assess its effectiveness in improving soil quality. A randomized complete block design with three replicates was employed.

Composition and selected properties of bio-waste collected in towns from single- and multi-family housing and in rural areas.

The progress of civilisation contributes, among other things, to an increase in the mass of waste produced in households. A significant part of it is bio-waste (about 31% in Poland). It is generally agreed that bio-waste is a suitable substrate for valorisation through fermentation with biogas production.

Demonstration of Near Edge X-ray Absorption Fine Structure Spectroscopy of Transition Metals Using Xe/He Double Stream Gas Puff Target Soft X-ray Source.

A near 1-keV photons from the Xe/He plasma produced by the interaction of laser beam with a double stream gas puff target were employed for studies of L absorption edges of period 4 transitional metals with atomic number Z from 26 to 30. The dual-channel, compact NEXAFS system was employed for the acquisition of the absorption spectra. L absorption edges of the samples were identified in transmission mode using broadband emission from the Xe/He plasma to show the applicability of such source and measurement system to the NEXAFS studies of the transition metals, including magnetic materials.

Morphological and Optical Characterization of Colored Nanotubular Anodic Titanium Oxide Made in an Ethanol-Based Electrolyte.

In this paper, the possibility of color controlling anodic titanium oxide by changing anodizing conditions of titanium in an ethanol-based electrolyte is demonstrated. Colored anodic titanium oxide was fabricated in an ethanol-based electrolyte containing 0.3 M ammonium fluoride and various amounts of deionized water (2, 3.
