Abstract: The ieu river, a tributary of the Some u Mare river, streams from the north – eastern end of the C limani mountains, at the contact between the peaks of the C liman Mountains and the Bistri a Depression, under the C liman piedmont. The genesis and spatial development of the ieu river basin is the result of its position in the northern extremity of the Transylvanian Depression, but also of the Transylvanian – Pannonian micro-board mobility, which generated a series of changes of the subsidence areas in the lower sector of the ieu River. The relief of the Transylvanian Depression, by its actual appearance, is but a short sequence of the series of geomorphological changes. Distinguishing them may follow different paths depending on the purpouse, requirements and possibilities, one of which is represented by the analysis of the morphogenetic manifestation in the valley – slope systems, based on methodological support provided by functional geomorphology. Attention will be directed to the S r el sector – the juncture with the Some u Mare river, where contemporary alluvial processes (alluvial bed elevation, the presence of sloughing sectors) the appearance of sectors due to the saliferous Quaternary neotectonics, the agrotecnical exploitation of land use, contribute to changes in the report of the slope – valley system. In this fluvial geomorphology study the spatio – temporal frame of the analysed system accounts for 268 km2, of a total of 1691 km2. The alternation of some saliferous horizons (the S rata and S r el Valleys) with other more friable ones (clays, marls, gravel) in addition to the fact that it is fully visible, it induces differentiations even in the water bed, valley sectors. The emergence of a series of wide NV–SE axial – plane separations: the Sl tini a anticline, the T rpiu synclinal, confer unicity to the sector.
Innis and the Emergence of Canadian Communication/Media Studies
Robert E. Babe
Global Media Journal : Canadian Edition , 2008,
Abstract: The discussion in this paper examines the influence of Harold Innis’ medium theory on contemporary media and communication scholarship in Canada and abroad. The methodological construction of Innis’ medium theory comprises several dimensions including: media bias; the exercising of power through the use and control of media; the bias of communication media toward favouring control over space and control through time; the role of governance in overcoming the bias inherent in media; a materialist understanding of civilizations; space-media outpacing time-media; and dialectics. In this paper particular attention is given to two issues. The first is the connections between Innis’ political economy approach and the work of Marshall McLuhan on the one hand, and the ecological studies of David Suzuki on the other. Both McLuhan and Suzuki, it is argued, may be seen as filling in important gaps in Innis’ work. The second focuses on the reasons why Innis’ medium theory has struck a chord with the Canadian psyche. This stands in stark contrast to the apparent neglect of Innis’ work within American media and communication scholarship.

Abstract: The main carotenoids identified using high performance liquid chromatography were lutein and ?-carotene. Muscat Ottonel variety has the highest ?-carotene concentration 504.9?μg/kg for organic and 593.2?μg/kg for conventional grapes. For the organic farming, the total polyphenols content were in the range of 163.23 – 1341.37?mg GAE/kg fresh weight (FW) and 148.47 – 1231.38?mg GAE/kg FW for the conventional grapes. The highest ORAC values were obtained for blue-black variety Napoca in both farming system (43.5?±?0.95?μmol TE/g organic; 40.4?±?0.5?μmol TE/g conventional) and lowest for Aromat de Ia?i (16.8?±?0.6?μmol TE/g organic; 14.7?±?1.6?μmol TE/g conventional). Napoca variety showed also the highest antioxidant activity measured by DPPH method in both cultivated system.Nine grape varieties cultivated in organic and conventional systems were compared regarding the carotenoids, total polyphenols and antioxidant activity. The white grape varieties have a higher carotenoids content compared with the blue-black cultivars while the blue-black varieties contain higher TPC and exhibit higher antioxidant activity (except for Muscat Hamburg-ORAC). Vitis vinifera grape skins originating from wine or table grape varieties can be used as a potential source of natural antioxidants.The grape berries are important since they are consumed as fruits, wine, juice or raisins and are largely cultivated for the wine industry. Grapes contain a wide range of chemical substances such as sugars, organic acids, mineral salts, vitamins, enzymes and also phytochemicals which are responsible for the sensory characteristics of wines [1] and for their health properties [2].Antioxidant activities of grapes are due to the presence of antioxidant components such as flavonoids, phenolic acids, anthocyanins and carotenoids. Carotenoids play important roles in human nutrition through their provitamin A activity, but also by acting as antioxidants, for prevention of age-related macular degeneration or
