Reconstruction of historical geodetic systems for their implementation in reprojection algorithms
No full textHistorical cartography is an important source of geographic information for diachronic studies. The Italian geodetic datum from the second half of the 20th century are well known and used, while the reference systems used previously do not have a certain documentation also because they were developed by the military geographical institute, which at the time was a uniquely military body with the related problems of confidentiality.The reconstruction of the datum of each single historical map is a fundamental process, in order to be able to correctly compare historical information with the current ones, but it is complex because of the scarce information available on the type of datum and cartographic projection used for the production of the map.The reconstruction of the ancient morphology of an area, such as that of 1893 Forma urbis map or the pre-reclamation maps of Agro Pontino, is of fundamental importance for various studies on geomorphological changes of the territory, including, for example, the reconstruction of diverted and/or covered watercourses.Many of the Italian historical maps have been referred to the ellipsoid of Bessel with different orientations that in many cases are the same used previously or simultaneously for public purposes including, in particular, the drafting of the cadastral cartography.

Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods

No full textComparative efficacy of once-daily ciclesonide and budesonide in the treatment of persistent asthma
No full textBackground: The aim of this study was to compare the efficacy and safety of once-daily ciclesonide, a new-generation, on-site-activated, inhaled corticosteroid, with once-daily budesonide in persistent asthma. Methods: Eligible patients requiring budesonide or equivalent 320-640 mu g (ex-mouthpiece, equivalent to 400-800 mu g; Turbohaler (TM)) daily entered a 2-week baseline, and then a 2- to 4-week pretreatment period (budesonide 1280 mu g/day; ex-mouthpiece, equivalent to 1600 mu g/day). Patients with an increase in forced expiratory volume in 1s (FEV1) of >= 7% or >= 0.15 L were randomised to ciclesonide 320 mu g (ex-actuator, equivalent to 400 mu g ex-valve) via a hydrofluoroalkane-metered dose inhaler (HFA-MDI) without a spacer or budesonide 320 mu g once daily in the morning for 12 weeks. Change in FEV1 was the primary endpoint. Results: In all, 359 patients were randomised. The FEV1 and forced vital capacity (FVC) decreased by 0.18 and 0.12 L, respectively, in the ciclesonide group, and by 0.23 and 0.21 L in the budesonide group. For FEV1, ciclesonide was noninferior and numerically superior to budesonide. For FVC, ciclesonide was statistically superior to budesonide (P = 0.010). Asthma symptom scores were comparable; the median percentage of symptom-free days was significantly higher for ciclesonide (43.6%) versus budesonide (25.8%) (P = 0.017). Rescue medication use decreased significantly only for ciclesonide patients (P = 0.009). Frequency of adverse events was low in both groups. Conclusion: Ciclesonide 320 mu g once daily by HFA-MDI without a spacer was at least as effective as budesonide 320 mu g once daily in persistent asthma
Depression influences the quality of diabetes-related self-management activities in elderly patients with type 2 diabetes: a cross-sectional study
No full textGabriela Mut-Vitcu,1 Bogdan Timar,2 Romulus Timar,1 Cristian Oancea,3 Ioan Cosmin Citu4 1Second Department of Internal Medicine, 2Department of Functional Sciences, 3Department of Infectious Diseases, 4Department of Obstetrics and Gynecology, “Victor Babes” University of Medicine and Pharmacy, Timisoara, Romania Purpose: To evaluate the prevalence of depression and its impact on the quality of diabetes-related self-care activities in elderly patients with type 2 diabetes. Patients and methods: In this cross-sectional study, 184 patients with type 2 diabetes were enrolled. Depression was evaluated using Patient Health Questionnaire-9 while the quality of diabetes-related self-care activities was assessed using the Summary of Diabetes-Related Self Care Activities Questionnaire. Results: In our study group, 53.3% of the patients had moderate depression, 17.9% had severe depression, and 28.8% had no depression symptoms. Patient’s age (P=0.024), presence of diabetic neuropathy (P<0.001), and body mass index (P=0.037) proved to be independent and significant predictors for developing depression in patients with type 2 diabetes. The severity of depression was reverse correlated with the quality of self-care activities for all the studied components: global score (r=-0.305), diet intervention score (r=-0.297), exercise score (r=-0.388), glycemic monitoring score (r=-0.055), and feet care score (r=-0.180). The presence of severe depression was associated with an increased prevalence of diabetes complications such as diabetic neuropathy and chronic kidney disease. Conclusion: The prevalence of depression is higher in patients with type 2 diabetes compared to general population. Depression has a major negative impact on the quality of diabetes-related self-care activities and, being a treatable condition, proactive screening followed in case of a positive diagnosis by adequate treatment should be performed in all patients with diabetes.

Collective excitations in the superdeformed well
No full textCollective excitations are commonplace features in nuclei at normal deformation. It has been suggested that both in the A\sim 190 and 150 superdeformed (SD) nuclei, collective vibrational states might occur in the same excitation energy range as quasi-particle and single-particle excitations. In particular, the large deformation associated with SD nuclei brings together orbitals from many spherical shells and leads to the close proximity of states with opposite parity, favouring octupole shape vibrations. However, to date, \sim 200 SD bands have been reported in more than 50 nuclei and in most cases, the excited SD bands have been interpreted as single or quasi-particle excitations. Only in very few cases, has the collective excitation scenario been suggested. Where are the collective states in SD nuclei? The question is particularly relevant in even--even A=190 nuclei in which SD states are observed at lower rotational frequency and hence the additional influence of the pair gap makes the collective excitations more competitive with quasi-particle excitations.F.
