  open access

  • S. Mania
  • R. Tylingo

  The dataset contains the results of a single series of determinations of the microbiological purity of the cosmetic based on the aqueous phase in the test for the total number of bacteria and the total number of yeasts.The tests were performed by preparing a series of decimal dilutions of the cosmetic in peptone water and performing in-depth culture...

• Usefulness of the voltamperometric method for assessment of the purity of soil

  Publikacja

  - Measurement Automation Monitoring - Rok 2014

  This paper presents a voltammetric analysis of soil. It shows that the voltammetry is a useful method for the assessment of soil contaminated with heavy metal ions. There are two major problems with voltammetry analysis: the diffusion coefficient and the measurement system. The paper contains a short literature study of mathematical equations and a study of differences between soil and water measurements. Suggestions of the solution...

• Bacterial nanocellulose as a microbiological derived nanomaterial

  Publikacja

  • A. Stanisławska

  - Advances in Materials Science - Rok 2016

  Bacterial nanocellulose (BNC) is a nanofibrilar polymer produced by strains such as Gluconacetobacter xylinus, one of the best bacterial species which given the highest efficiency in cellulose production. Bacterial cellulose is a biomaterial having unique properties such as: chemical purity, good mechanical strength, high flexibility, high absorbency, possibility of forming any shape and size and many others. Such a large number...

  A parity path in a vertex colouring of a graph is a path along which each colour is used an even number of times. Let Xp(G) be the least number of colours in a proper vertex colouring of G having no parity path. It is proved that for any graph G we have the following tight bounds X(G) <= Xp(G) <=|V(G)|− a(G)+1, where X(G) and a(G) are the chromatic number and the independence number of G, respectively. The bounds are improved for...

• Microbiological corossion of metallic products as a result of biofilm

  Publikacja

  • M. Krzemiński
  • M. Supernak

  - Advances in Materials Science - Rok 2008

  Warunkiem do pojawienia się korozji mikrobiologicznej jest utworzenie na powierzchni metalu biofilmu. Zawiera on biologicznie czynne mikroorganizmy wraz z produktami ich przemian metabolicznych. Biofilm ogranicza dyfuzję produktów metabolizmu wytwarzanych przez poszczególne komórki mikrokolonii. Powoduje to, że produkty uboczne tych przemian gromadzą się w bezpośrednim sąsiedztwie metalu. Gdy powierzchnia metalu nie jest odporna...
