    Az elvĂ©gzett kutatĂĄs arra irĂĄnyult, hogy felmĂ©rjĂŒk az egĂ©szsĂ©gĂŒgyi centrumoktĂłl tĂĄvol esƑ, Szabolcs-SzatmĂĄr-Bereg megye ÚjdombrĂĄd közsĂ©g lakĂłinak betegsĂ©g specifikus tudĂĄsĂĄt, jelen esetben a stroke-kal kapcsolatban. Ezen tĂșlmenƑen megvizsgĂĄltuk, mennyire hatĂ©konyak a prevenciĂłs elƑadĂĄsok, a lakossĂĄg mennyire tartja ezeket hasznosnak, Ă©s hogy tartanak-e igĂ©nyt tovĂĄbbi, mĂĄs betegsĂ©gekrƑl szĂłlĂł elƑadĂĄsoknak is.

    A reverse engineering mĂłdszerek gyakorlati alkalmazĂĄsĂĄval az utĂłbbi idƑben egyre gyakrabban merĂŒlnek fel a visszamodellezett objektumokon vĂ©gzett tervezĂ©si feladatok. KorĂĄbban a pontfelhƑ alapĂș geometriai elemeken vĂ©gezhetƑ mƱveletek korlĂĄtosak voltak, azonban az elmĂșlt Ă©vekben bevezetett konvergens modellezĂ©si technolĂłgia ezeket a korlĂĄtokat feloldotta. Jelen cikkben a konvergens modellezĂ©si technolĂłgia nĂ©hĂĄny gyakorlati pĂ©ldĂĄjĂĄt ismertetjĂŒk

    Jelen kutatĂĄs cĂ©lja gimnĂĄziumi tanulĂłk szexuĂĄlis magatartĂĄsĂĄnak feltĂ©rkĂ©pezĂ©se Ă©s annak vizsgĂĄlata, hogy mennyire hatĂ©kony a kivĂĄlasztott intĂ©zmĂ©nyben a szexuĂĄlis nevelĂ©s. A vizsgĂĄlatban összesen 300 fƑ vett rĂ©szt. A tanulĂłk ĂĄtlagĂ©letkora 17,51 Ă©v (szĂłrĂĄs: 1,38) volt. A kapott eredmĂ©nyeink alapjĂĄn elmondhatĂł, hogy a tanulĂłk közel fele 15 Ă©vesen, vagy annĂĄl fiatalabb Ă©letkorban kezd nemi Ă©letet Ă©lni. Ugyan a leggyakrabban alkalmazott fogamzĂĄsgĂĄtlĂł mĂłdszer a kondom volt körĂŒkben a legutĂłbbi aktus sorĂĄn, igen magas azok arĂĄnya, akik egyĂĄltalĂĄn nem vĂ©dekeztek. A STUDY OF YOUNG PEOPLE’S SEXUAL BEHAVIOUR AMONG HIGH SCHOOL STUDENTS – A STUDY WITH INITIAL RESULTS The aim of the present study is to measure the sexual behaviour of high school students and to examine the effectiveness of sex education in the selected institution. A total of 300 people participated in the study. The mean age of the students was 17.51 years (standard deviation: 1.38). Nearly half of the students start having sex at the age of 15 or younger. Although the most commonly used method of contraception was the condom among them during the last act, the proportion of those who did not defend themselves at all was very high

    The Self-incompatibility Locus and Chloroplast DNA Regions of Prunus domestica Reflect the Origin and Genetic Diversity of Traditional Cultivars

    A traditional cultivar, Besztercei Bt.2, and a clone of an autochthonous landrace (Nemtudom P3) of the hexaploid European plum (Prunus domestica) were studied to highlight their breeding perspectives. Five self-incompatibility ribonuclease (S-RNase) alleles were detected in both cultivars, with one allele shared. DNA sequence analysis confirmed it as a new, previously unidentified allele in P. domestica, which we labeled as S18. This allele was found to share ∌99% identity with the Prunus spinosa SB-RNase allele. Because Prunus species are readily hybridizing, sequence variations in 10 chloroplast DNA regions and nuclear internal transcribed spacers were studied to check if ‘Nemtudom P3’ and ‘Besztercei Bt.2’ are indeed P. domestica. The majority-rule consensus tree of maximum likelihood and Bayesian inferences confirmed it, and also indicated genetic differentiation with ‘Nemtudom P3’ and ‘Besztercei Bt.2’ forming a statistically supported subclade within the P. domestica germplasm. Our results pointed to some regions of the P. domestica chloroplast genome (trnS-trnG-trnG, trnC-ycf6, and trnD-trnT) that can be used to detect intraspecific variations. The proportion of parsimony informative characters compared with the total length of amplified regions was the highest in the case of nrITS with 12.1%. The S-genotyping of 68 wild-growing Nemtudom trees showed the genetic consequences of long-term vegetative propagation and occasional crossing between Besztercei and Nemtudom accessions. Controlled pollinations confirmed the self-compatibility of ‘Nemtudom P3’. By clarifying their phylogenetic position, and characterizing the S-locus, our results will help breeding P. domestica cultivars and pave the way to understanding how the S-locus works in a hexaploid Prunus species

    A Three-Dimensional Analysis of Magnetic Nanopattern Formation in FeRh Thin Films on MgO Substrates: Implications for Spintronic Devices

    Magnetic nanopatterns were successfully created in FeRh thin film deposited on MgO (100) substrates. Silica and polystyrene spherical masks, nominally 500 and 1000 nm in diameter, respectively were applied on the surface of the sample in order to locally shadow the film against the effect of 110 keV energy neon-ion irradiation with fluences of 10 15 and 10 16 ions/ cm2 . Such nanosphere-lithography technique allows for projecting the mask geometry on the magnetic structure of the FeRh film. Conversion-electron Mö ssbauer spectroscopy and magnetic force microscopy were used to determine the ferromagnetic ratio and the magnetic pattern in the samples, and nuclear resonance scattering of synchrotron radiation was applied to obtain the in- depth magnetic profile. From the results obtained, the possible three-dimensional (3D) structure of the created individual magnetic domains was also constructed. Overall, the great customizability of the presented nanosphere-lithography technique in FeRh thin film provides opportunities for developing cutting-edge spintronic applications

    Synergy effect of temperature, electric and magnetic field on the depth structure of the FeRh/BaTiO3 composite multiferroic

    Get PDF
    FeRh based composite multiferroic materials have attracted great scientific interest due to their wide variety of possible applications in future nano device technology. In the recent work, a comprehensive study on the depth dependence of the metamagnetic phase transition in FeRh/BaTiO3 heterostructure is reported by means of single or combined external stimulus such as heat, magnetic or electric field. Grazing-incidence nuclear scattering experiments revealed significant discrepancies in the mechanism of the antiferromagnetic/ferromagnetic reor- dering induced by the different effects, with distinguished role of both upper and lower interfaces
