  - Year 2015

  Sports, hunting and military shooting grounds are well known sources of noise that can be disruptive both for people present at those facilities, as well as for people and animals that live nearby. What is more, shooters are also subjected to very painful and dangerous impulse noise. The paper discusses the issues related to the noise immission during firing of small firearms of military type that are typical for Poland. The experiments...

• Handel targowy jako faux pas

  Publication

  • K. Krause-Brykalska

  - KULTURA POPULARNA - Year 2013

  Współcześnie występujący handel targowy w przestrzeni publicznej posiada dwoisty charakter, polegający na niejednoznacznej odpowiedzi na pytanie czy powinno się ingerować współczesną architekturę w organizację targowisk czy jarmarków. Może tego rodzaju wydarzenia stanowią pewnego rodzaju nostalgię za tą pierwotną żywiołową formą handlu, której już się nie odnajdzie w galeriach handlowych, hipermarketach, gdzie rzesze ludzi pracują...

  • S. Sappati
  • J. Czub

  - Journal of Physical Chemistry Letters - Year 2024

  G-quadruplexes (G4s) are nucleic acid structures crucial for the regulation of gene expression and genome maintenance. While they hold promise as nanodevice components, achieving desired G4 folds requires understanding the interplay between stability and structural properties, like helicity. Although right-handed G4 structures dominate the experimental data, the molecular basis for this preference over left-handed helicity is unclear....

  - Year 2014

  Cylindrical steel tanks are very popular shell structures used to store the products of chemical and petroleum industries. Any failure might have disastrous consequences, therefore their safety and reliability is essential. Earthquakes are the most dangerous and also the most unpredictable dynamic loads acting on such structures. On the other hand, mining tremors are usually considered to be less severe due to lower acceleration...

  The effects of interference of pressure waves in simple piping systems were studied. A freeware computer code Allievi developed at the University of Valencia was used to simulate dynamic waveforms in simple and complex networks. The tests were carried out according to three scenarios. No pressure increases significantly exceeding the Joukowsky pressure in simple cases were noticed. When the effects of the simultaneous closing of...

  - DISCRETE AND CONTINUOUS DYNAMICAL SYSTEMS - Year 2011

  In mathematical biology and the theory of electric networks the firing map of an integrate-and-fire system is a notion of importance. In order to prove useful properties of this map authors of previous papers assumed that the stimulus function f of the system ẋ = f(t,x) is continuous and usually periodic in the time variable. In this work we show that the required properties of the firing map for the simplified model ẋ = f(t) still...

  We describe a novel method for the quality assessment of oil utilized for deep frying. The method is based on the analysis of frying fumes using a custom electronic nose. The quality score could be obtained after less than 3 min of analysis and without interrupting the frying process or sampling the oil directly. The obtained results were correlated with the peroxide value using a multivariate linear regression model. The most...
