Impact of anthropometric factors on chest compression depth during CPR provided by children aged 11-14 in a community-wide study.

Objective: To assess the depth of chest compressions (CC) provided by schoolchildren and their relation with providers's anthropometric characteristics.

Methods: We organized 1-hour hands-on training sessions for 11-14y.o.

The Potential Risk of Nanoparticulate Release from Photocatalytic Pavement Concrete Surface Due to a Simulated Abrasion Load-An Experimental Study.

The risk of the releasing of nanometric particles from construction materials with nanometric components might be one of the biggest threats to further development of them. One of the possible ingress routes to human organisms is the respiratory system. Therefore, it is crucial to determine the risk of emission of nanometric particles during material usage.

Ozone Formation during Photocatalytic Oxidation of Nitric Oxides under UV Irradiation with the Use of Commercial TiO Photocatalytic Powders.

The application of photocatalytic materials has been intensively researched in recent decades. The process of nitric oxide (NO) oxidation during photocatalysis has been observed to result in the formation of nitric dioxide (NO). This is a significant factor of the photocatalysis process, as NO is more toxic than NO.

Application of Photocatalytic Concrete Paving Blocks in Poland-Verification of Effectiveness of Nitric Oxides Reduction and Novel Test Method.

Photocatalytic concrete is one of the most promising concrete technologies of the past decades. Application of nanometric TiO to cement matrices enables the reduction of harmful airborne pollutants. Although a number of implementations of this technology are described in this paper, problems related to test conditions are also reported.

Induced seismicity response of hydraulic fracturing: results of a multidisciplinary monitoring at the Wysin site, Poland.

Shale oil and gas exploitation by hydraulic fracturing experienced a strong development worldwide over the last years, accompanied by a substantial increase of related induced seismicity, either consequence of fracturing or wastewater injection. In Europe, unconventional hydrocarbon resources remain underdeveloped and their exploitation controversial. In UK, fracturing operations were stopped after the M 2.
