Il primo messale ungherese a stampa
No full textThe article tries to present the history of the formation of the first Hungarian printed missal, the Missale to usum dominorum ultramontanorum. First, based on the results of specific literature, it specifies the purchaser of the edition: Antal Sánkfalvi, prebendary of Vác, then ambassador in most places of King Matthias Corvinus. The second part of the study attempts to investigate the reasons for the release of the liturgical book, and try to find traces of the use of the missal. The author puts forward the hypothesis that the release of the missal results from a pure economic calculation and that the book was (also) used in the Archdiocese of Esztergom, accordingly the missal should be considered a Missale strigoniense
Volume-delay functions of minor junctions created by micro-simulation
No full textIn network modeling, several junctions of the physical road network are often left out from the network model due to different factors. The paper focuses on the possibility of incorporating the effects of these junctions into the model with the adjustment of volume-delay function parameters through micro-simulation models. Parameter sets were determined for typical road junctions, similar results were merged to reduce multitude within the set. Recommendations are given to incorporate the results into transportation network models
The supervision of passenger car unit values in different types of urban junctions with VISSIM program
No full textIn this research it will be accomplished the supervision of valid passenger car unit values, which are applied in effective road technical specifications. It was used VISSIM micro simulation program made by PTV Ag. It has been examined four different types of junctions (T-intersections, 4-leg intersections, signalized intersections, roundabouts).Simulation running have been completed to the different types of junctions with different types of vehicles, random factors and volume of traffic from which it could be defined those PCU values, which indicate current traffic situations. They have been compared to values applied at the moment and I propose PCU values for capacity calculations

In vitro antifugal activity of medicinal plant extract against Fusarium oxysporum f. sp. lycopersici race 3 the causal agent of tomato wilt
No full textMedicinal plant extracts of five plants; Adhatoda vasica, Eucalyptus globulus, Lantana camara, Nerium oleander and Ocimum basilicum collected from Cairo, Egypt were evaluated against Fusarium oxysporum f. sp. lycopersici race 3 in vitro conditions using water and certain organic solvents. The results revealed that cold distilled water extracts of O. basilicum and E. globulus were the most effective ones for inhibiting the growth of F. oxysporum f. sp. lycopersici. Butanolic and ethanolic extracts of the tested plants inhibited the pathogen growth to a higher extent than water extracts. Butanolic extract of O. basilicum completely inhibited the growth of F. oxysporum f. sp. lycopersici at concentrations 1.5 and 2.0% (v/v). Butanolic extracts (2.0%) of tested plants had a strong inhibitory effect on hydrolytic enzymes; β-glucosidase, pectin lyase and protease of F. oxysporum f. sp. lycopersici. This study has confirmed that the application of plant extracts, especially from O. basilicum for controlling F. oxysporum f. sp. lycopersici is environmentally safe, cost effective and does not disturb ecological balance. Investigations are in progress to test the efficacy of O. basilicum extract under in vivo conditions
Multiplication and growth of hybrid poplar (Populus alba × P. tremula) shoots on a hormone-free medium
No full textThe present study explored an alternative approach for poplar micropropagation, based on the restriction of gas exchange between inside and outside environments of culture vessel, rather than on the application of exogenous hormones. Apical and nodal stem segments (explants) excised from in vitro-developed shoots of hybrid white poplar (Populus alba L. × P. tremula L.) were incubated in either sealed (with Parafilm) or unsealed capped glass culture tubes (150 × 20 mm) on a hormone-free Woody Plant Medium. Shoot proliferation on apical explants was observed in sealed culture tubes but not in the unsealed ones; the difference between these two samples in respect of shoot number increased in the course of time and became threefold after three months of culture, with 3.2 ± 0.4 (mean ± SE) shoots per explant in the sealed tubes versus 1.1 ± 0.1 in the unsealed ones (for comparison, the mean shoot numbers on nodal explants were 2.4 ± 0.3 and 3.4 ± 0.4 in the unsealed and sealed culture tubes, respectively). Moreover, the shoots taken from the sealed culture tubes could be distinguished by superior shoot length, if compared to the shoots from the unsealed tubes, during the subsequent culture stage under uniform conditions
Effects of environmental factors on sperm motility and fertilization rate of Phascolosoma esculenta
No full textThe study investigated the effects of environmental factors (salinity, pH, ions and activation media) on sperm motility (activation rate, duration of quick movement, and lifespan) and fertilization rate of Phascolosoma esculenta. The results showed that spermatozoa in the coelom and nephridium are able to move quickly. The optimal salinity was 14.64 to 43.35 and the optimal pH was 6.46 to 9.53 for sperm activation and motility, whereas the ranges for fertilization were narrower (18.56 to 30.3 for salinity and 6.46 to 8.61 for pH). Of the ions studied, Na+ was indispensable for sperm motility and fertilization, and Ca2+ and Mg2+ were necessary for fertilization. P. esculenta sperm could not fertilize eggs and have short lifespans in 200 to 600 mmol/L NaCl and KCl solutions. Furthermore, they could not be activated or move in 200 to 600 mmol/L CaCl2, MgSO4, and sucrose solutions
Comparison of anti-acetylcholinesterase activity of bulb and leaf extracts of Sternbergia candida Mathew & T. Baytop
No full textStudies on Alzheimer’s disease have been highlighted due to increasing prevalence of this disease. Oldest hypothesis about the pathophysiology strengthens the research of cholinesterase inhibitors for treatment. Amaryllidaceae plants are well known for alkaloids showing cholinesterase inhibiting activity. Among them, Sternbergia species gained attention as a source of metabolites of these alkaloid contents. Studies have focused mainly on the bulbs of these plants. In this study the potential acetylcholinesterase (AChE) inhibitory activity of endemic Sternbergia candida Mathew & T. Baytop (Sc) species was evaluated in both bulbs and leaves in comparison with lycorine. We report for the first time that methanol and chloroform leaf extracts of the plant show AChE inhibitory (AChEI) activity. Among the leaf extracts methanolic extract was much more potent than chloroform extract by means of AChE inhibition. Although IC50 values for methanolic extract was found to be lower than reference drug lycorine; this value of inhibition did not reach to a statistically significant level. Future studies aiming at investigation of the AChE inhibitory activity could be considered using leaves of the plant
Detection of DNA damage caused by cryopreservation using a modified SCGE in large yellow croaker, Pseudosciaena crocea
No full textWe used single-cell gel electrophoresis (SCGE) to detect the integrity of sperm DNA of the teleost large yellow croaker, Pseudosciaena crocea, cryopreserved with Cortland solution and a range of 5% to 30% DMSO concentrations in order to test how sperm cryopreservation affected the DNA stability of nuclei. Electrophoresis was conducted for 60 min at 130 mA and 15 V. The comet images were analyzed with software CometScore 1.5, and parameters such as comet length, tail length and percentage DNA in the tail were obtained. Then the comet rate and damage coefficient were calculated. Results demonstrated that there were no significant differences in motility, comet rate and damage coefficient between fresh sperm and cryopreserved sperm stored in 5%, 10%, 15% and 20% DMSO, while the sperm cryopreserved with 25% and 30% DMSO had a lower motility, higher comet length and damage coefficients than those of fresh sperm. There was a positive correlation between comet rate of cryopreserved sperm and the concentration of DMSO. Our results demonstrate that toxicity of the cryoprotectant is the main cause of DNA damage in cryopreserved sperm nuclei
