The abundance of water has certainly been a very important resource for the development of the Po Valley and has necessitated, more than once, interventions of regulation and drainage that have contributed strongly to imprint a particular conformation on the land. Already in Roman times there were numerous projects of canalisation and intense and diligent commitment to the maintenance of the canals, used for navigation, for irrigation and for the working of the mills. The need to control the excessive amount of water present was the beginning of the exploitation of this great font of richness that was constantly maintained in subsequent eras. In the early Middle Ages, despite the conditions of political instability and great economic and social difficulty, the function of the canals continued to be of great importance, also because the paths of river communication often substituted land roads, then left abandoned. After the 11th century A.D. the resumption of agricultural activity was conducive to the intense task of land reclamation of the Lombardian countryside and of commitment by the cities to amplify their waterways with the construction of new canals and the improvement of those already existing. The example given by Milan, a city lacking a natural river, that equipped itself with a dense network of canal, used in various ambits of the city life (defence, hygiene, agriculture, transport, milling systems) and for connections with the surrounding territory, can be considered as emblematic. In the surrounding countryside, the activity of the Cistercian monks of Chiaravalle represents one of the situations more indicative of how land reclamation and waterways contributed fundamentally to the organisation of the territory over the span of the ages.
The research article address, the mechanical properties such as fatigue, impact strength and tribological properties of Austempered ductile iron (ADI) has been investigated. The samples of ADI iron were austenitized at 927°C for 2 hrs and later it was under austempering process for 2 hrs at a temperature range of 240°C to 400°C. Experiments under axial loading has been carried out on three different compositions (without Ni(X), 0.22 wt % Ni (X1), 0.34 wt. % Ni (X2). Fabricated test bars were converted in to as per ASTM standard samples for different tests. In order to study the influence of chunky nickel morphology studies on fatigue life and impact strength were carried out on a second set of specimens without any microstructural defect. Metallurgical analyses were performed on all the samples of heat treated samples (AF – Ausferrite, MB – Mixed bainite, M – Martensite, RA – Retained Austenite and N-Nodule) were found and compared. It was found that a mean content of 22% of chunky nickel in the microstructure (with respect to total Ni content) influence considerably the fatigue and impact strength properties of the cast iron. Moreover tribological properties of the specimens were also studied under dry sliding conditions at various sliding speed and load. The wear resistance and coefficient of friction were found to increase with increase in load and sliding speed.
Designed as an introduction to the topic of „The Bible in Culture", this article is, by its very nature, synthetic. The author merely wanted to signal the necessity of a new approach to the Biblical literature which was by no means being created in isolation, independently of rich cultural milieu. For Israel, such an environment was not only a great civilization of Egypt, Anatolia or Mesopotamia but also traditional religions of Syria and Palestine. The metaphor of the seed sown into the soil, to which the Gospel so often refers, has its deep meaning also when applied to the Old Testament. Biblical authors were firmly rooted in the culture of their era, transgressing the borders of the chosen nation. However, with time a tendency would appear of Israel closing itself to the influence of the pagan world. Christ, neverthe- less, addresses his good news to all peoples (Mt 28,19), which presupposes its inculturation depending on the milieu of a given epoch.
This article is an attempt to identify the main themes in the literary work of Zygmunt Haupt, a Polish writer, journalist and painter, who emigrated to the United States in the aftermath of World War II. His writings show a keen awareness of the issue of absence/presence and the related problems of memory traits, identity and literary representation. Drawing on the psychoanalytical criticism of Jacques Lacan and Julia Kristeva and the philosophy of Jacques Derrida, this reading of Haupt’s fi ction, especially his short stories (whose collected edition was published in 2007 under the title The Basque Devil), is a critical reassessment of his work. As a storyteller he excels in the depiction of scenes of terror, desire and the uncanny. The article argues Haupt’s work represents not only a remarkable literary achievement but also offers an interesting study case for critics whose approach is founded on literary theory, psychoanalysis and anthropology.
