  • Sample preparation techniques for determination of pesticide residues in food samples
    Publication

    - Year 2012

    Pesticides are very important in increasing the efficiency and quality of agricultural production. They are applied in many spheres of life, not only in agriculture, and their applications are expanding. Despite their numerous merits, pesticides are some of the most toxic substances contaminating our environment and have a negative impact on the human health. Properties of pesticides such as stability, ability to bioaccumulation...

  • Sample Rate Conversion with Fluctuating Resampling Ratio
    Publication

    In this paper a sample rate conversion with continuously changing resampling ratio has been presented. The proposed implementation is based on variable fractional delay filter implemented using a Farrow structure. It have been demonstrated that using the proposed approach instantaneous resampling ratio can be freely changed. This allows for simulation of audio recored on magnetic tape with nonuniform velocity as well as removal...

  • Sano-Tachiya-Noolandi-Hong versus Onsager modelling of charge photogeneration in organic solids

    W pracy obliczono numerycznie charakterystyki polowe wydajności fotogeneracji nośników ładunku na gruncie różnych wesrsji modeli Onsagera i Noolandiego-Honga. Wyznaczone krzywe teoretyczne porównano z wynikami doświadczalnymi uzyskanymi metodą elektromodulacji (foto)luminescencji (EML) dla próżniowo naparowanych warstw organicznych kompleksów Alq3 i Ir(ppy)3.

  • Sampling Strategies: Statistics of Sampling
    Publication

    Each step of the analytical procedure has a significant influence on the final result of the analysis. In the majority of cases the analytical procedure encompasses sampling because the analysis of the entire object (material) is usually not possible. Thus it is necessary to include the uncertainty related to sampling procedure in the uncertainty budget calculations. In the paper: the most important properties of the analysed...

    - JOURNAL OF THE ELECTROCHEMICAL SOCIETY - Year 2015

    Carbon paper covered with side-naphthylated multi walled carbon nanotubes was used as the conducting support for the construction of a biocathode in a hybrid biofuel cell. Laccase Carrena unicolor enzyme was employed as the catalyst for the 4e reduction of oxygen and a zinc disc covered with hopeite was used as the anode. Derivatized carbon nanotubes increase the working surface of the electrode and provide direct contact with...

  • Satellite inventory of tram track geometrical layout

    In the paper a methodology of restoring of railway track’s geometrical shape in a horizontal plane on the base of conducted mobile satellite surveying was presented. The authors proposed a calculating algorithm for designing the track sections placed in horizontal arcs. In the algorithm an analytical methodology with mathematical formulas is applied. The procedure has an universal character, i.e. provides the possibility of varying...

  • SAWING PROCESS AS A NEW ALTERNATIVE WAY OF DETERMINING SOME WOOD PROPERTIES
    Publication

    - Year 2015

    Cutting forces (power) could be considered from a point of view of modern fracture mechanics. The developed cutting model, derived from fracture mechanics, includes work of separation (fracture toughness) in addition to plasticity and friction, and also dullness of the cutting edge described by the cutting edge radius. Moreover, forecasting of the shear plane angle for the cutting models, broaden possibilities of energetic effects...

  • Sawing Processes as a Way of Determining Fracture Toughness and Shear Yield Stresses of Wood
    Publication

    - BIORESOURCES - Year 2015

    A new computational model, based on fracture mechanics, was used to determine cutting forces. Unlike traditional computing methods, which depend on many coefficients reflecting the machining of solid wood, the new model uses two main parameters: fracture toughness and shear yield stresses. The aim of this study was to apply this new method to determine these parameters for the tooth cutting edge principal positions and longitudinal...
