    Referendum ogólnokrajowe w republikach bałtyckich po 1991 roku – analiza porównawcza

    Get PDF
    Direct democracy is seen as a complementary form of government in relation to representative democracy. It is intended to compensate for the shortcomings of representative democracy, and to ensure the direct participation of citizens in the exercise of power. One of the institutions of direct democracy, guaranteed in the constitutions and other legal acts of Lithuania, Latvia and Estonia is a nationwide referendum. Despite the similar historical experiences and convergent solutions adopted in political systems, nationwide referendum performs other functions. It is a derivative of social and political problems of these countries, as well as the shape of the political scene.Demokracja bezpośrednia jest postrzegana jako komplementarna forma sprawowania władzy względem demokracji przedstawicielskiej. Z założenia ma rekompensować niedostatki demokracji pośredniej, a także gwarantować bezpośredni udział obywateli w sprawowaniu władzy. Jedną z instytucji demokracji bezpośredniej, gwarantowaną w konstytucjach i innych aktach prawnych Litwy, Łotwy i Estonii, jest referendum ogólnokrajowe. Pomimo podobnych doświadczeń historycznych i zbieżnych rozwiązań przyjętych w systemach politycznych referendum ogólnokrajowe spełnia inne funkcje. Jest to pochodną problemów społecznych i politycznych tych państw, jak również kształtu sceny politycznej

    [EN] The aim of the study was to learn about the structure of broiler rabbit skins, with the possibility of using them as dressing for gloves and shoe uppers. The histological structure, organoleptic and rheological properties of leathers such as tensile and puncture strength, energy state based on dynamic tests and topography map of their thickness were assessed. The study material included the skins of two groups of hybrid rabbits (F1), 24 pieces each, from breeds crossing: ♂ Belgian Giant Grey × ♀ Burgundy (BOS×BU), or ♂ Belgian Giant Grey × ♀ New Zealand White (BOS×BNZ). Histological, rheological, organoleptic and topography thickness studies of broiler rabbit leathers have proven that they can be intended for the production of not only gloves, but also shoe uppers. The leathers of BOS x BU hybrid proved to be a better raw material than BOS x BNZ for the production of both gloves and footwear.This work was supported by the Ministry of Science and Higher Education of Poland (DS-3245).Zapletal, P.; Bierowiec-Widórek, K.; Czerniejewska-Surma, B.; Maj, D.
