Analytical solutions of the Klein-Fock-Gordon equation with the Manning-Rosen potential plus a Ring-Shaped like potential

In this work, on the condition that scalar potential is equal to vector potential, the bound state solutions of the Klein-Fock-Gordon equation of the Manning-Rosen plus ring-shaped like potential are obtained by Nikiforov-Uvarov method. The energy levels are worked out and the corresponding normalized eigenfunctions are obtained in terms of orthogonal polynomials for arbitrary $l$ states. The conclusion also contain central Manning-Rosen, central and non-central Hulth\'en potential.Comment: 14 pages. arXiv admin note: substantial text overlap with arXiv:1210.537

Apical extrusion of debris using reciprocating files and rotary instrumentation systems

Background: To compare the preparation time and amount of apically extruded debris after the  preparation of root canals in extracted human teeth using the reciprocating files and rotary nickel.titanium systems.Procedure: Sixty extracted human mandibular premolars were used. The root canals were instrumented using reciprocating (WaveOne, Reciproc, SafeSider) or rotary motion (Typhoon, ProTaper Universal,  Mtwo), and the debris produced was collected in glass vials. The remaining debris was assessed using a microbalance and statistically analyzed using the one.way ANOVA and Duncan multiple range tests at a significance level of P < 0.05. The time required to prepare the canals with different instruments was also recorded.Results: The Reciproc group produced significantly less debris when compared to the Typhoon group (P < 0.05), and instrumentation with the single.file systems was significantly faster than in the multi.file systems (P < 0.05). The WaveOne group extruded significantly more debris per unit of time than the other groups, with the exception of the Typhoon group (P < 0.05).Conclusion: According to our study, all systems caused apical debris extrusion. However, the Reciproc group was associated with less debris extrusion when compared to the other groups.Key words: Apical extrusion, endodontics, single file system

Induction of logical relations based on specific generalization of strings

Learning logical relations from examples expressed as first order facts has been studied extensively by the Inductive Logic Programming research. Learning with positive-only data may cause over generalization of examples leading to inconsistent resulting hypotheses. A learning heuristic inferring specific generalization of strings based on unique match sequences is shown to be capable of learning predicates with string arguments. This paper describes an inductive learner based on the idea of specific generalization of strings, and the given clauses are generalized by considering the background knowledge. ©2007 IEEE

Conservation value of the native Hungarian wild grape (Vitis sylvestris Gmel.) evaluated by microsatellite markers

Wild grape (Vitis sylvestris GMEL.) has became a highly threatened species in Europe because of habitat loss, competition with alien grape species and intensive forest exploitation. Twenty-three Vitis spp. samples were analysed at 8 microsatellite loci to estimate the genetic diversity of the natural Vitis sylvestris specimens. In order to analyse the morphological traits and to perform molecular analysis, 11 native individuals were sampled from 6 remnant Hungarian habitats of the wild grape. To compare the genetic relationships among the wild specimens, samples from Turkish habitats, as well as cultivars of Vitis vinifera, Vitis labrusca and Vitis riparia were also included. Genetic diversity was higher within the Hungarian wild grape locations, with a mean of He = 0.74, which was higher that of samples originating from a larger area of Turkey, He = 0.69. Most of the Hungarian samples formed a well-defined, separate branch on the NJ tree. Based on the morphological traits and molecular analysis on the territory of Szentendre Island, formerly considered to be one of the largest native locations of wild grape, interspecific hybrids of Vitis sylvestris and Vitis riparia were identified. It can be concluded from the results that most of the Hungarian habitats studied could be valuable for the conservation. This paper reports on Hungarian Vitis sylvestris habitats, providing the first genetic study on diversity and on the relationship of Vitis sylvestris to other Vitis specimens, wild or cultivated, in the central part of the Carpathian Basin

СОЗДАНИЕ ГИБРИДОВ ТОМАТА НА ОСНОВЕ МАТЕРИНСКИХ ФОРМ С ФУНКЦИОНАЛЬНОЙ МУЖСКОЙ СТЕРИЛЬНОСТЬЮ

The rate of variability of functional male sterility (ps–2) depending on year of study, genotype and age of the plant is shown. The efficiency of the method of forced ejection of pollen from intact anthers to increase the degree of sterility is shown. The five tomato hybrids developed based on selected lines were submitted for the state variety trial of Moldova.На примере двенадцати линий показана степень изменчивости функциональной мужской стерильности (ps-2) в зависимости от года исследования, генотипа и возраста растений. На примере крупноплодной линии показана эффективность метода принудительного выбивания пыльцы из неповрежденных пыльников для повышения степени стерильности. С участием выделенных линий созданы и переданы в государственное испытание Молдовы пять гибридов томата

Effects of Prolonged Intravenous Flunixin Meglumine in Healthy Dogs

This study was designed to evaluate possible side effects on liver and kidney functions and haematological indices, associated with long-term intravenous (IV) administration of flunixin meglumine in healthy dogs. For this purpose, 12 dogs were divided into 2 equal groups. Group 1 was intravenously given flunixin meglumine at the dose of 1.1 mg/kg/day for 5 days and g-roup 11 received 2.2 mg/kg/day IV for 5 days. Blood samples were withdrawn before treatment (day 0), 2 h post injection on each day of treatment and one day after the last injection for biochemical (glucose, sodium-Na, potassium-K, chloride-Cl, creatinine, urea, alkaline phosphatase-AP, alanine amino transferase-ALT and total protein) and haematological (bleeding time, coagulation time, red blood cell, white blood cell, platelet count, differential leukocyte count, haematocrit and haemoglobin) analyses. Faecal and urine samples were collected on the same days as blood samples for the presence of any abnormalities. The results revealed a significant increase in bleeding (P < 0.001) and coagulation time (P < 0.001) and a decrease in platelet count (P < 0.001) in both groups. There was also a significant increase in the concentration of Na and Cl in group 1 and an elevation in AP (P < 0.00 07 ALT (P < 0.001) and glucose (P < 0.001) in group II. Blood in urine and faeces was also evident in both groups. The results may suggest that the dose of 1.1 mg/kg IV for 5 d does not cause any significant side effects provided that no bleeding disorder exists. and the dose of 2.2 mg/kg IV for 5 d should not exceed 3 d as liver enzymes began to increase significantly afterwards
