  - Year 2004

  W pracy przedstawiono podstawowe pojęcia i definicje zwiazne z wyszukiwaniem informacji rytmicznej w utworach muzycznych. W muzykologii przyjmuje się, że atrybuty dźwięku, takie jak długość, częstotliwość oraz amplituda dźwięku determinują wagę rytmiczną dźwięku. W artykule przebadano te właściwości fizyczne dźwięku w kontekście okreslenia wagi rytmicznej, czyli miary określającej tendencję dźwięku do znalezienia się na początku...

• Antioxidants: a premature scientific hypothesis that reshuffled the traditional food pyramid

  Publication

  • A. Bartoszek-Pączkowska

  - Year 2014

  Antioxidants present in substantial amounts in foods, plant-based products in particular, have been suggested as chemopreventive agents that can curb the development of undesirable health effects caused by oxidative stress simply by enriching diet in such compounds. This idea has been enthusiastically accepted by consumers, as well as food and pharmaceutical industry, and created great demand for products containing antioxidant...

• The “autumn effect” in the gold market—does it contradict the Adaptive Market Hypothesis?

  Publication

  • M. Potrykus
  • U. Augustynowicz

  - International Journal of Management and Economics - Year 2024

  The present study aims to verify the autumn effect in the gold market, first presented 10 years ago by Dirk Baur in the paper “The autumn effect of gold” and to investigate the calendar effects occurring for other precious metals. This empirical research is presented in a way to place the results obtained in the context of the Efficient Market Hypothesis (EMH) and the more current Adaptive Market Hypothesis (AMH). The study was...

• How Does International Competitiveness Affect Economic Development? A Two-Phase Hypothesis

  Publication

  • H. G. Adamkiewicz
  • S. M. Kot

  - Optimum. Studia Ekonomiczne - Year 2014

  This paper analyses the impact of international competitiveness on economic development, based on the World Economic Forum Global Competitiveness Index (GCI) and GDP/capita of 125 countries during the period 2007-2010. The results reveal two phases of the evolution of competitiveness. When GCI < 4.5 (on 1-7 scale), any improvement of a country’s competitiveness affects current development more than future development. When...

  Rozpuszczalne produkty mikrobiologiczne (SMP) są związkami organicznymi wytwarzanymi podczas rozkładu substratów przez mikroorganizmy osadu czynnego. Zbadano mikroskopowo zmiany składu zespołów mikrobiologicznych (organizmów jedno- i wielokomórkowych) pod wpływem obniżonego lub zwiększonego poziomu SMP. Wysoka zawartość SMP w znacznym stopniu zmieniła skład zespołów mikrobiologicznych, od orzęsków osiadłych (12-175 µm), do...

  Set S ⊂ V is called secure set iff ∀ X ⊂ S | N [ X ] ∩ S | ≥ | N ( X ) \ S | [3]. That means that every subset of a secure set has at least as many friends (neighbour vertices in S) as enemies (neighbour vertices outside S) and will be defended in case of attack. Problem of determining if given set is secure is co −NP -complete, there is no efficient algorithm solving it [3]. Property testers are algorithms that distinguish inputs...

  In this paper we propose new algorithmic methods giving with the high probability the correct answer to the decision problem of security in graphs. For a given graph G and a subset S of a vertex set of G we have to decide whether S is secure, i.e. every subset X of S fulfils the condition: |N[X] \cap S| >= |N[X] \ S|, where N[X] is a closed neighbourhood of X in graph G. We constructed a polynomial time property pseudotester based...

  Currently, there are numerous methods that can be used to neutralize pathogens (i.e., devices, tools, or protective clothing), but the sterilizing agent must be selected so that it does not damage or change the properties of the material to which it is applied. Dry sterilization with hydrogen peroxide gas (VHP) in combination with UV-C radiation is well described and effective method of sterilization. This paper presents the design,...

  As access to space conditions becomes more available, both technically and economically, scientists’ interest in launching finer and more sophisticated experiments grows. To be qualified for launch, such experiments need to be carefully tested prior to the event. The tests should represent actual launch conditions as closely and in a detailed manner. Typical tests for payload include: vibration tests, thermal and vacuum tests,...

  Examining the condition of wooden elements is crucial from the perspective of proper structure performance. If the deterioration in the internal wood condition, which displays no symptoms visible from the outside, is detected, the further spread of the deterioration can be prevented. Test results often point to the necessity of conducting repairs and, renovations, replacing the structure of wooden beams, or even substituting a...

  Pharmaceutical development is mostly focused on the research leading to approval of a new and viable active substance. However, there is a number of old generation compounds that are still being used in contemporary medicinal practice. So that new analytical developments should cover not only the safety of newly developed drug substances, which is obvious, but should also be directed into the search of individual stability issues...
