ABSTRACTThe Danube region in Central Europe was one of the areas where several cultures appeared before moving further or being defeated during the Migration Period in the middle of the first millennium AD. The Lombards, who crossed the Danube in 505 AD, settled in the “Tullnerfeld” where the Maria Ponsee graveyard was excavated in 1965–1972. From the historical evidence about the temporal and spatial migration of the Lombards, it was concluded that the graveyard was in use between 505 and 568 AD by three groups of migrants. We processed and dated a new set of 23 bones, found in the Maria Ponsee site. The determined 14C dates fit well in the expected time interval, though discrimination between the grave groups could not be obtained. The dates were added to the chronological sequence, recording the Migration Period in Central Europe. The sequence lead to a good correlation of the modelled and historical data (Amodel = 87.6%). The results show differentiations of the respective tribes in the pre-Lombardic period. However, transitions between the Lombard phases were rather ambiguous, indicating that the Lombards set up new settlements while only partially abandoning the already inhabited ones before 546 AD.

Late Roman

The problem of identification of the earliest Slavic settlement in central Europe drew researchers’ attention to the archaeological finds of the Late Roman and Migration periods. The simple hand-made pottery of this period in the northern Danube region showed a certain formal resemblance to the vessels of Early Slavic cultures, which provoked the idea of a direct time connection between the first wave of the Slav expansion from the east and the horizon of the preceding Germanic settlement in this territory. A find group from northeast Slovakia, known mainly from the small settlement at Presov (Chropovský 1962; Točík 1965; Chropovský & Ruttkay 1985), the ’Prešov‘ type, seemed to provide the geographical connection of this ethnic shift. However, different opinions were also expressed, pointing to a possible relationship with the Late Przeworsk culture milieu (Budinský-Krička 1963: 36–7), or connecting the genesis of the Prešov finds with the development of local settlement of the Later Roman period (Lamiová-Schmiedlová 1969: 478; Kolník 1980: 202). Investigations in the North Carpathian area has provided new evidence during the last few years enabling a first evaluation of its settlement.

The early Neolithic rondel is a large curvilinear ditched and palisaded enclosure found in increasing numbers in Central Europe. It has close links with the tells of the Danube region, themselves highly suggestive instruments of the earliest Neolithic. Here the authors extend the distribution of rondels further to the north-east, with the discovery and verification of the first example in Poland. As they point out, it is aerial photography that made this advance possible and we can expect many more discoveries, given appropriate investment in the art.

Four religious cultural settings, a Slovenian Catholic one, a Bosnian Muslim one, a Serbian Orthodox one and an American Protestant one, are compared on the basis of a variety of measures of religiosity, resulting from a survey carried out on large student samples in 2005. Certain cultural peculiarities of the groups emerge: e.g., the particular Muslim stress on the concept of God as austere judge. These peculiarities, indicative of a more pronouncedly rigid and authentic religiosity do not add up to a qualitatively different religiosity among the Muslims. Nevertheless, clear differences appeared in the structure of religiosity, which are of particular relevance to the two more intensively religious groups: the American Protestants and the Bosnian Muslims. The former group's religiosity is more dependent on social pressure, and its religious practice is more frequent, whereas the latter group's religiosity seems better linked to their personality set-up and integrated in personality. The American Protestants are slightly more inclined to sacrifice their life both for religious purposes and for their country.

Harmonic contributions of utility and customer may feature significant variations due to network switchings and changing operational modes. In order to correctly define the impacts on the grid voltage distortion the frequency dependent impedance characteristic of the studied network should be accurately measured in the real-time mode. This condition can be fulfilled by designing a stimuli generator measuring the grid impedance as a response to injected interference and producing time-frequency plots of harmonic contributions during considered time interval. In this paper a prototype of a stimuli generator based on programmable voltage source inverter is developed and tested. The use of ternary pulse sequence allows fast wide-band impedance measurements that meet the requirements of real-time assessment of harmonic contributions. The accuracy of respective analysis involving impedance determination and calculation of harmonic contributions is validated experimentally using reference characteristics of laboratory test set-up with varying grid impedance.

Introduction: The only option for treatment of end stage liver diseases is liver transplantation. Afzalipour Hospital in Kerman, Iran is the third largest liver transplantation center in Iran. In this study, the outcomes of this center have been studied during the past 5 years. Methods: In this cross-sectional study, the pre and post transplantation’s clinical, demographic and outcome data of all patients who received liver transplant at Afzalipour Hospital during the past 5 years have been collected and reviewed. SPSS software ver. 16 was used to analyze the data. Results: Forty-three patients have received liver transplantation during this time interval. The 3-year survival rate of patients was 77%. The most common cause of death was primary nonfunction graft after transplantation. The most common complication was acute rejection (15%), all of which were successfully treated with corticosteroids. Conclusion:  Due to increment of cases of acute and chronic liver failure in the community and since the final treatment of these cases is liver transplantation, so there is need to develop liver transplant centers in the future. Quantitative and qualitative study of the activity of centers based liver transplant in Iran is necessary to set up successful centers.

A procedure was developed for dealing with two problems that have impeded the use of quantal parameters in studies of transmitter release. The first, involving temporal and spatial biasing in the estimates for the number of functional release sites (n) and probability of release (p), was addressed by reducing temporal variance experimentally and calculating the bias produced by spatial variance in p (var(s)p). The second, involving inaccuracies in the use of nerve-evoked endplate potentials (EPPs), was circumvented by using only miniature EPPs (MEPPs). Intracellular recordings were made from isolated frog cutaneous pectoris, after decapitation and pithing of the animals, and the concentration of K+ ([K+]) was raised to 10 mM to increase the level of transmitter release. The number of quanta released (m) by the EPP was replaced by the number of MEPPs in a fixed time interval (bin), and 500 sequential bins used for each quantal estimate. With the use of 50-ms bins, estimates for var(s)p were consistently negative. This was due to too large a bin (and introduction of undetected temporal variance) because the use of smaller bins (5 ms) produced positive estimates of var(s)p. Increases in m, n, and p but not var(s)p were found in response to increases in [K+] or [Ca2+]/[Co2+]. La3+ (20 microM) produced increases in m and n, which peaked after 20 min and declined toward zero. There were also large increases in p and var(s)p, which peaked and declined only to initial control values. The increase in var(s)p was presumed to reflect La(3+)-induced release of Ca2+ from intracellular organelles. The results suggest that this approach may be used to obtain unbiased estimates of n and p and that the estimates of var(s)p may be useful for studying Ca2+ release from intraterminal organelles.

The aim of this paper is to develop a cooperative control model for improving the operational efficiency of Bus Rapid Transit (BRT) vehicles. The model takes advantage of the emerging connected vehicle technology. A connected vehicle centre is established to assign a specific reservation time interval and transmit the corresponding dynamic speed guidance to each BRT vehicle. Furthermore, a set of constraints have been set up to avoid bus queuing and waiting phenomena in downstream BRT stations. Therefore, many BRT vehicles are strategically guided to form a platoon, which can pass through an intersection with no impedance. An actual signalized intersection along the Guangzhou BRT corridor is employed to verify and assess the cooperative control model in various traffic conditions. The simulation-based evaluation results demonstrate that the proposed approach can reduce delays, decrease the number of stops, and improve the sustainability of the BRT vehicles.

AbstractThis study investigates the low-frequency (interannual and longer period) variability in three hydroclimatic records from east Central Europe. Two of these records consist of climate proxies derived from oak-tree rings in Bakta forest, and Balaton Highlands in Hungary, for the time interval 1783-2003. The third record consists of homogenized instrumental precipitation data from Budapest, Hungary, from 1842 to 2003. Using wavelet analysis, the three time series are analyzed and compared with one another. It is found that all three time series exhibit strong interannual variability at the 2-4 years timescales, and these variations occur intermittently throughout the length of each record. Significant variability is also observed in all the records at decadal timescales, but these variations persist for only two to three cycles. Wavelet coherence among the various time series is used to explore their time-varying correlation. The results reveal significant coherence at the 2-4 years band. At these timescales, the climatic variations are correlated to the tree-ring signal over different time intervals with changing phase. Increased (decreased) contribution of large-scale stratiform precipitation offers a potential explanation for enhanced (faded) coherence at the interannual timescale. Strong coherence was also observed occasionally at decadal timescales, however these coherences did not appear uniformly. These results reinforce the earlier assertion that neither the strength nor the rank of the similarity of the local hydroclimate signals is stable throughout the past two centuries.

Faunal Exploitation

This paper focusses on animal remains associated with archaeological contexts dated to the middle and later phases of the Scandinavian Iron Age, which corresponds to the first millennium AD. The main question to be addressed is whether this record can be used for identifying human impact on certain animal populations for modelling faunal exploitation and interregional trade. In the first part of the paper, we undertake a detailed inventory of animal finds recorded in published excavation reports, research catalogues, and in existing databases maintained primarily by the Historical Museum in Stockholm. We compare the chronological pattern identified in the burial assemblages with a chronological sequence retrieved from pitfall hunting systems located in the Scandinavian inland region. The chronologies of the animal finds from burials and the pitfall systems are then compared with dated pollen-analytical sequences retrieved in the inland region and additional archaeological assemblages, such as graves and hoards of Roman coins. In our discussion, we outline an interregional model of faunal exploitation between AD 300 and 1200, including the possible location of hunting grounds and end-distribution areas for animal products. The paper provides deeper insights into the burial record of the middle Iron Age, arguing for the need for broader interregional approaches, and focussed archaeological research in the inland regions of Scandinavia.
