Objective: to investigate whether changes in the QT interval observed with IVA are entirely due to bradycardia or also to the direct effects of IVA on ventricular repolarisation. Methods: Because the non-linear relationship between the QT interval and the heart rate may often result in underor overestimation of the corrected QTc interval by the conventional Bazett (QTcB) and Fridericia (QTcF) formulae, respectively, a population correction formula (QTcP) was used. The QTcP formula was developed and validated in 23,997 QT/RR paired values from the ECGs in 1216 patients with coronary artery disease randomised to the placebo arm of several IVA efficacy studies. The QTcP formula was then used for rate correction of the QT interval in 995 patients randomised to treatment with IVA 10 mg bid. Eighty-three patients treated with atenolol 100 mg od served as active controls. Results: Based on the analysis of the QT/RR values in the placebo group, the QTcP formula resulted in a correction exponent of 0.384. Prolongation of the uncorrected QT interval was observed in patients treated with IVA or atenolol consistent with a reduction in heart rate (Figure). There were no changes in the corrected QTc interval throughout the follow-up period. Conclusion: The effects of IVA and atenolol on the QT interval is solely related to bradycardia with no evidence of any direct effect on repolarisation. The QTcP correction formula allows accurate QTc interval assessment.

At the foot of the terrace, a small stream flows, a left tributary of the Dâmbovnic River. Through magnetometric scanning of the southern area of the tell, a delimitation trench was revealed, which was made at the base of the anthropic mound. The separation element was also identified based on aerial photographies. Also a series of soil corings made on two main transects, North-South and East-West oriented, showed the existence of a stratigraphy thicker than 2.50 meters. Moreover, in the areas between the inhabited space itself – which was central, and the delimitation ditch of the tell, a series of sediments were identified, which can be connected to the conscious action of erecting the anthropic mound. 100 meters North ...

This allowed us to analyse the spatial distribution of the Roman roads. Within the administrative territory that belonged to the ancient city of Tropaeum Traiani traces of Roman roads were identified, some of them attested by milestones. Their routes can be reconstituted by studying aerial photographs and satellite images which represent the main source since few traces have been preserved on the ground. By corroborating information from the field, attesting rural settlements, villae rusticae, aqueducts, fortifications, funerary barrows and quarries, with those obtained by mapping archaeological traces visible on image sources, we were able to get a clearer picture of the organization of the territory of the city during the Roman times. We used GIS (ArcMap 9.3) to obtain a digital terrain model using spatial layers containing spot heights, hydrographical network and hill shades. All the imagery collected was used as a base layer for the interpretation of the archaeological information. Our results show that the network of roads and settlements is far denser than previously identified by means of systematic archaeological research or field investigation. This type of analysis allows not only the reconstruction of ancient landscape, but also provides a solid basis for identifying specific characteristics and evolution of this area during the Roman period.
Rezumat: Prin studiul coroborat și interpretarea informațiilor provenite din surse arheologice, fotografii aeriene și imagini satelitare s‑a realizat o hartă a diferitelor structuri arheologice din teritoriul orașului Tropaeum Traiani. Pe baza lor s‑a putut analiza distribuția spațială a drumurilor romane, ale căror urme pe teren sunt sporadice, prezența lor fiind documentată doar în unele cazuri prin descoperirea unor stâlpi miliari. Traseul drumurilor poate fi reconstituit prin studierea fotografiilor aeriene și a imaginilor satelitare. Acestea reprezintă principala sursă, deoarece, în prezent, urme ale drumurilor romane nu se mai păstrează. Coroborând informațiile care atestă așezări rurale, villae rusticae, apeducte, fortificații, movile funerare și cariere, cu cele obținute prin cartografierea urmelor arheologice vizibile pe fotografii, s‑a putut obține o imagine mai clară a rețelei de drumuri și implicit a organizării teritoriului orașului în vremea stăpânirii romane. Pentru realizarea unui model digital al terenului s‑a folosit GIS (ArcMap 9.3), care are la bază contururile reliefului din zonă și altitudinile acestuia, precum și informațiile privind rețeaua hidrografică. Fotografiile avute la dispoziție au reprezentat suportul principal pentru interpretarea informațiilor arheologice. Rezultatele cercetării arată că rețeaua de drumuri și așezări este mult mai densă decât se credea anterior, în mod aproape exclusiv pe baza investigațiilor de teren. Acest tip de analiză permite nu numai reconstruirea peisajului antic, ci oferă, de asemenea, o bază solidă pentru identificarea caracteristicilor și evoluția acestei zone în perioada romană.

The monument was mentioned by Pamfil Polonic in late 19th century, mentioned again by Ioana Bogdan Cătăniciu, in 1970s, "in the eastern part of the forest", but difficult to spot on all recent orthophotos. The modern agriculture make things difficult day by day, in the matter of monuments' identification and preservation. A post-script of the paper would be that the dyke was identified both in the field and in the forest (in October 2015), on the track suggested by that lucky "one shot".

A graphic of the heights (deposit thickness) as a function of the tell diameters, allowed us to outline several intervals, generally operable: small (H≤2 m, D≤40 m), medium (2 m<H≤4 m, 40 m<D≤75), and large (H>4 m, D>75 m). The last category also includes the tell from Stoenești–Măgura Tangâru, the case study for this paper. A conjugated analysis of the results obtained from aerophotogrammetry, 3D laser scanning, and magnetometric and georadar surveying, bears out that the tell from Stoenești developed on an extension of the terrace of the Câlniștea brook; the difference revealed by the topographic survey performed using the 3D scanner, between the upper portion of the terrace and, respectively, of the tell, correspond to the maximum amplitude revealed by previous archaeological investigations—ca. 4.60/4.70m. Similarly, the aerial identification of a demarcation ditch dug at the base of the terrace onto which the larger tell developed, as well as of a smaller ditch surrounding a smaller tell (ca. 10m to the south), was confirmed by the magnetometric and GPR surveys. The fact that the delineation ditch of the main tell was dug at approximately 6m below the base of the anthropic levels, on the foot of the terrace's natural slope, precludes any defensive behaviour. The scenario from Tangâru seems to occur in the case of all large-scale tells developed on terraces or terrace extensions—all the similar sites investigated in the Chronos project, as well the sites previously researched, were enclosed by ditches dug at the base of the geomorphologic understructure onto which they developed.
