Pękanie drutu stanowi stale zagrożenie dla wydajności procesu obr bki elektroerozyjnej drutem (WEDM). Prace badawcze mają na celu zbadanie i zrozumienie zjawiska pękania drutu przy użyciu trzech r żnych elektrod drutowych, a mianowicie drutu mosiężnego gladkiego, drutu mosiężnego dyfuzyjnego i drutu mosiężnego pokrytego cynkiem, w odniesieniu do obr bki stopu Inconel 718 przy użyciu procesu WEDM. W tym celu przeprowadzono badania eksperymentalne w celu zbadania wplywu sześciu parametr w procesu wejściowego, a mianowicie czasu trwania impulsu, czasu wylączenia impulsu, prądu szczytowego, napięcia iskry, prędkości posuwu drutu i napięcia drutu na częstotliwośc pękania drutu przy użyciu trzech r żnych elektrod drutowych. Celem eksperyment w jest wyb r najbardziej odpowiedniego materialu drutu, kt ry charakteryzuje się minimalną "częstotliwością pękania drutu", a także określenie zakres w wszystkich parametr w wejściowych procesu dla wybranego drutu, w kt rych można wykonac skuteczną i wydajną obr bkę Inconelu 718. Wyniki eksperyment w wykazaly, że drut mosiężny pokryty cynkiem o średnicy 0,25 mm zapewnia najlepszą wydajnośc pod względem częstotliwości pękania drutu w por wnaniu z drutami mosiężnymi zwyklymi i dyfuzyjnymi dla wszystkich parametr w procesu.

Imperial Texas examines the development of Texas as a human region, from the simple outline of the Spanish colony to the complex patterns of the modern state. In this study in cultural geography set into a historical framework, D. W. Meinig discusses the "various peoples of Texas, who they are, where they came from, where they settled, and how they are proportioned one to another from place to place." After examining the historical framework, he then presents detailed analyses of the major regions of modem Texas and an over-all characterization of the state and its people. He concludes that, although Texas has never been the empire that it has sometimes been called, "nevertheless... Texas is something more than just one-fourteenth of the American area, one-twentieth of the American people, and one-fiftieth of the American union."
