INTRODUCTION Secondary bladder neck sclerosis (BNS) represents a common late complication of prostate surgery, however so far insufficiently assessed in the available literature. More over, the previously attempted and analyzed therapeutic modalities failed to achieve acknowledgement as standard treatment for this particular pathology. METHODS The bipolar plasma vaporization (BPV) was introdu...

( Under Energy Strategy 2050, the federal government of Switzerland plans to greatly reduce per capita energy consumption, decrease the share of fossil fuels, and replace the nuclear electricity generation by gains in efficiency and use of renewable energy sources. This work investigates the feasibility of defined goals through both the improvement of the efficiency of current energy systems an...

A typical electrothermal vaporization (ETV) using a tantalum was built for low-pressure ICP-AES. The analytical performance of the ETV was tested and compared with that of a PFA pneumatic nebulizer with a double membrane desolvator (DMD). The limits of detection of the ETV were obtained in the range of 3.4 ng to 758 ng for Zn, Cu, Co, Fe, and Mg, while those of the PFA nebulizer were in the ran...

A new type of district energy network capable of providing simultaneously heating and cooling is being investigated. It is based on the use of CO2 as a heat transfer fluid by taking advantage of the latent heat of vaporization, to store and transfer heat across the network. The goal of the present study is to determine the performance of a CO2 network when applied to a real urban area. It focus...

We report unconventional flow visualization coupled with two-dimensional numerical modeling in the Heliotron solar reactor used for nanomaterial synthesis. The effect of operating conditions, such as gas ejection velocity and configurations sweeping on particle transport were investigated order to map different regimes experienced during ablation. experimentally observed phenomena satisfactoril...
