• A Generalized Version of the Lions-Type Lemma

  Publikacja

  • M. Chmara

  - Annales Mathematicae Silesianae - Rok 2023

  In this short paper, I recall the history of dealing with the lack of compactness of a sequence in the case of an unbounded domain and prove the vanishing Lions-type result for a sequence of Lebesgue-measurable functions. This lemma generalizes some results for a class of Orlicz–Sobolev spaces. What matters here is the behavior of the integral, not the space

• The shadowing chain lemma for singular Hamiltonian systems involving strong forces

  Publikacja

  • M. Izydorek
  • J. Janczewska

  - Central European Journal of Mathematics - Rok 2012

  W niniejszym artykule rozważamy autonomiczny układ Hamiltonowski na płaszczyźnie z potencjałem, który ma punkt osobliwy (studnię nieskończonej głębokości) i maksimum globalne właściwe równe zero przyjmowane w dwóch różnych punktach płaszczyzny. Przy założeniu, że w otoczeniu punktu osobliwego potencjał spełnia warunek Gordona(gradient tego potencjału w otoczeniu punktu osobliwego jest tzw. silną siłą, ang. a strong force) dowodzimy...

• The saga of a fish: from a survival guide to closing lemmas

  Publikacja

  • S. Kryzhevich
  • E. Stepanov

  - JOURNAL OF DIFFERENTIAL EQUATIONS - Rok 2019

  In the paper by D. Burago, S. Ivanov and A. Novikov, “A survival guide for feeble fish”, it has been shown that a fish with limited velocity can reach any point in the (possibly unbounded) ocean provided that the fluid velocity field is incompressible, bounded and has vanishing mean drift. This result extends some known global controllability theorems though being substantially nonconstructive. We give a fish a different recipe...

• Utilizing Morphological and Physiological Parameters of Lemna minor for Assessing Tetracyclines’ Removal

  Publikacja

  • A. Bęś
  • K. Warmiński
  • W. Truszkowski
  • P. Kowal

  - MOLECULES - Rok 2024

  Antibiotics with significant environmental toxicity, e.g., tetracyclines (TCs), are often used in large quantities worldwide, with 50–80% of the applied dose ending up in the environment. This study aimed to investigate the effects of exposure to tetracycline hydrochloride (TC) and minocycline hydrochloride (MIN) on L. minor. Our research evaluated the phytotoxicity of the TCs by analyzing plant growth and biomass and evaluating...

  - Rok 2015

  A new generation of tanks for LNG transportation has been designed. Mass reduction forced our customer to use three different materials: austenitic steel, aluminium alloy and LNG compressed wood between them. The expertise concerns structural node between tank foundation and suspension. Expertise contains: description of object of test, test principals, results and conclusions
