Introduction: One of the problems that the delivery of continuous positive airway pressure (CPAP) via a helmet poses is the generation of noise.The objective of our study was to assess the Bow effect that the use of filter has on sound pressure levels generated by the delivery of positive airway pressure at different gas flow rates.Materials and Me
The aim of the paper was to determine the level of market concentration of the Polish investment fund industry in the period of 1998-2018 and to indicate the causes of its changes.Moreover, the intention of the study was to verify the hypothesis regarding competition on the market measured by the strength of an association between market positions
A land-cover-based linear BRDF (bi-directional reflectance distribution function) unmixing (LLBU) algorithm based on the kernel-driven model is proposed to combine the compact airborne spectrographic imager (CASI) reflectance with the moderate resolution imaging spectroradiometer (MODIS) daily reflectance product to derive the BRDF/albedo of the tw
Achieving sustainable development in countries prone to earthquakes is possible with taking effective measures to reduce vulnerability to earthquakes.In this context, damage assessment of hypothetical earthquakes and planning for disaster management are important issues.Having a computer tool capable of estimating structural and human losses from e
Abstract Rice is a major cereal food crop and staple food in most of the developing countries.India stands second in the production of rice next to China.Though almost 40,000 varieties of rice are said to exist, at present, only a few varieties are cultivated extensively, milled and polished.Even if white rice is consumed by most people around the
