Ground surface deformation of the urban area in complex engineering-geological conditions in the sinking town of Tuzla (Bosnia and Herzegovina)
No full textCDP-Colina: studio dose-effetto sulla sensibilità al contrasto in pazienti glaucomatosi.
No full textPurpose: To evaluate the effects of various doses of oral citicoline on a psycho-physical parameter connected with glaucomatous damage. Materials and Methods: Thirty-nine patients with open-angle glaucoma and a mild-advanced glaucomatous damage were recruited ( mean age 67.9; range 47-86 years). The patients were subdivided in 3 groups according to the type of treatment ( 400, 800 or 1200 mg/day). Another group of 12 untreated patients was the control group. Contrast sensivity was measured in each patient with Vistech VCTS 6000 system (Vistech Consultants Inc. Ohio USA) at baseline, at the end of the tretment, after 2 and 4 months of wash-out. The data were expressed like area under curve of contrast sensitivity ( AUC ) and processed by an analysis of variance. Results: After two months of treatment with citicoline an increase of 15% of the AUC values ( P< 0.001 ) is observed. This improvement already diminishes after 2 months of wash-out ( variation compared to baseline + 10%, P=NS) and practically it get exausted after 4 months of wash-out ( variation compared to baseline +4%; P=NS). Conclusions: Oral citicoline induces a temporary dose-dependent improvement of the contrast sensitivity in patients with glaucoma
Ground surface deformation of the urban area in complex engineering-geological conditions in the sinking town of Tuzla (Bosnia and Herzegovina)
No full textdeformation of the ground surface and buildings in the town of Tuzla. The southern edge of the deposit dips beneath the northern part of the town. Although relatively small size, the deposit represents an extremely complex geological body The slow, natural processes of dissolution of the deposit's eastern part were accelerated by industrial exploitation of saline water (brine) that lasted over 100 years. Exploitation of the western part of the deposit started much later in 1967, by classical dry underground mining. Natural processes and applied exploitation works endangered part of the town above the deposit. Subsidence has reached its peak in 70-s of the last century, when the city lost huge number of its residential, commercial and cultural facilities. Although the salt exploitation ended (2004 and 2007) very complex processes of degradation of wider deposit environment and urban areas are still ongoing, with visible consequences on the ground surface. Featured are the geodynamic phenomena and deformation caused by a complex
structural-tectonic structure of the terrain. Analyzed were also geodetic monitoring data for the period 1956-2010 which present important information about the processes of ground surface movements. Deformation on the ground surface is being developed under the influence of various factors. In the part of the town that was investigated and presented in this paper, the consequences of the salt deposit exploitation on the ground surface are predisposed by complex terrain structure
Dissertazione coronata dalla reale accademia dei georgofili di Firenze : in soluzione del seguente problema : se i maggesi, o riposi di uno, o più anni, che si danno alle terre in alcuna delle nostre comunità, a provincie, dipendano da cause fisiche, politiche, o morali, e come si possa rimediare a ciò in tutto, o in parte.

Appropriate Similarity Measures for Author Cocitation Analysis
No full textWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Horizontal movements of the ground surface in the zone of influence of salt exploitation in Tuzla (Bosna and Herzegovina).
No full textThis paper focuses on surface movements determined by geodetic methods and
occurred as consequence of brine extraction from Tuzla salt deposit (Bosnia and
Herzegovina). Previous studies were mainly concentrated on vertical movements, but
important information about behavior of the deposit is also available from horizontal
movement data. In the case of Tuzla salt deposit the geometry and spatial location of
leached/empty spaces are unknown and the comparative analysis of vertical and horizontal
movement could be really significant. The spatial identification of points with high values of
vertical and horizontal movements depends on the geometry of empty spaces. Investigation of
horizontal movements has been carried out analyzing data collected by several geodetic
measurements. The results obtained by the correlated spatial analysis of vertical and
horizontal movements, can identify basic geometric characteristics of the leached/empty
spaces. The discussed temporal intervals are two characteristic periods, reffered to the
capacity of the deposit exploitation. Movement rates per year and correlation between
horizontal and vertical movements are considered as indicator parameters defining the character of ground deformation. Spatial analysis of these coefficients values has identified
high risk areas, and gives additional information in thegeological structures definition
