Management of Complications in 1452 Pediatric and Adult Cochlear Implantations
Full text linkObjective: The aim of this study was to determine the short- and long-term complications after cochlear implantation (CI) procedures and to discuss the management and prevention of these complications.Methods: The study included a total of 1452 pediatric and adult cochlear implantation procedures performed in our clinic from March 2000 through September 2019. Of the 1452 implantations, 1201 were performed in children and 156 in adults. The minimum follow-up period was three months and maximum was 19 years. The mean age of the patients was 6.7±3.9 years (range, 10 months-69 years) at the time of their respective procedures. Complications were classified as major complications requiring reimplantation, major complications not requiring reimplantation and minor complications. All postoperative complications and treatment methods were examined.Results: A total of 148 (10.1%) complications were observed in the 1452 cochlear implants. Of these, 69 (4.75%) were major and 79 (5.44%) were minor complications. While 40 (2.75%) of the major complications required reimplantation, 29 (1.99%) did not. The most common cause of major complications leading to reimplantation was device failure (29 patients, 1.99%). The most common cause of minor complications was hematoma (21 patients). Total complication rates (6.68%) were significantly higher in children than in adults (3.51%) (p=0.00).Conclusion: Our 19 years of clinical experience has shown that CI is a successful and safe procedure that can be performed with low major complication rates. It is important to know the possible complications and to manage them correctly

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

Wallachia’s 1452 Currency Reform / with Mendeley dataset "XRF analysis: 23 Wallachian ducats (1452-1456)"
No full textThe 1452 monetary reform ended the period of significant currency transformations in medieval Wallachia. In 1451-1452, the Danubian Principality balancing between the Ottomans and the Hungarians, managed to launch the law and monetary reforms as well as a foreign policy change. The improvements were aimed at strengthening the Wallachian statehood. In 1452, Wallachian ruler-voivod Vladislav II resumed the activities at the local mint starting to hammer silver coins. The new denomination was so-called Muntenia ducat. Prior the monetary reform, the voivod had introduced Byzantine laws to Wallachia and got the Ottoman-Hungarian guarantees of his power as a Wallachian ruler. Consequently, Wallachia became the principality with a dualistic monetary system where silver Muntenia ducats and Ottoman silver aspri circulated together. The project contains a catalogue and analysis of metal of twenty-three Muntenia ducats hammered in 1452-1456. The specimens are in the author’s private collection of coins and medals. They are divided into four types: I, IIA, IIB and IIC. Heraldic shields on the ducat obverses are either Spanish or French. The inscriptions on the coins are composed of two Greek letters (IѠ) and Bulgarian words such as +IѠВЛАДНСЛАВОНВОДАГNЪ (+By the grace of God Vladislav voivoda lord). This expression was also the first sentence in Wallachian-Bulgarian documents issued by the Wallachian voivods in the XV century. A handheld XRF analyser Thermo Scientific Niton XL3t Goldd+ was taken to measure the composition of the coins’ metal at the University in Bergen. The Muntenia ducats 1452-1456 are basically composed of silver and copper: silver 83% - 97%, copper 1.5% - 15.3%. All coins have moderate traces of lead (0.11% - 0.69%) and gold (0.25% - 0.60%). Some ducats have got traces of iridium (0.44% - 0.93%) and zinc (0.03% - 0.05%), two of them traces of iron (0.11% - 0.19%). The monetary unit of measurement taken at the Wallachian mint in 1452 was presumably the Byzantine litra (λίτρα) borrowed through Bulgaria. The Byzantine-Bulgarian trail is quite obvious as Vladislav II began the Wallachian reforms by introducing the Byzantium laws, which came to Wallachia from Bulgaria. In 1451, the voivod ordered to copy the alphabetical directory of Byzantine laws Σύνταγμα κατὰ στοιχεῖον – Syntagma Canonum or Zaconicul. Previously, Sintagma was translated from Greek to Slavic in Serbia. A Slavic translation came from Serbia to Bulgaria and from there to Wallachia. The theoretical weight of the Byzantine silver litra was 327.60 g. According to the XRF analysis the Muntenia ducats contain 91% silver on average. Their average coin weight was presumably 0.60 g. Therefore one litra = 600 ducats (50 dozen). 0,60 g. х 91% = 0,546 g. (1) 327,60 g. / 0,546 g. = 600 ducats (2) 600 = 50 х 12 (3
