Szív-és érrendszeri megbetegedések közösségre irányuló prevenciója: fókuszban a stroke

Az elvégzett kutatás arra irányult, hogy felmérjük az egészségügyi centrumoktól távol eső, Szabolcs-Szatmár-Bereg megye Újdombrád község lakóinak betegség specifikus tudását, jelen esetben a stroke-kal kapcsolatban. Ezen túlmenően megvizsgáltuk, mennyire hatékonyak a prevenciós előadások, a lakosság mennyire tartja ezeket hasznosnak, és hogy tartanak-e igényt további, más betegségekről szóló előadásoknak is. COMMUNITY-BASED PREVENTION OF CARDIOVASCULAR DISEASE: FOCUS ON STROKE The aim of the study was to assess the disease-specific knowledge of the inhabitants of the municipality of Újdombrád in Szabolcs-Szatmár-Bereg County in this case in relation to strokes. In addition, we examined how effective the health education was, and how useful the population finds them, lastly if they want more additional lectures about other diseases

Konvergens modellezés és reverse engineering

A reverse engineering módszerek gyakorlati alkalmazásával az utóbbi időben egyre gyakrabban merülnek fel a visszamodellezett objektumokon végzett tervezési feladatok. Korábban a pontfelhő alapú geometriai elemeken végezhető műveletek korlátosak voltak, azonban az elmúlt években bevezetett konvergens modellezési technológia ezeket a korlátokat feloldotta. Jelen cikkben a konvergens modellezési technológia néhány gyakorlati példáját ismertetjük

Fiatalok szexuális magatartásának vizsgálata gimnáziumban tanuló fiatalok körében – egy vizsgálat kezdeti eredményei

Jelen kutatás célja gimnáziumi tanulók szexuális magatartásának feltérképezése és annak vizsgálata, hogy mennyire hatékony a kiválasztott intézményben a szexuális nevelés. A vizsgálatban összesen 300 fő vett részt. A tanulók átlagéletkora 17,51 év (szórás: 1,38) volt. A kapott eredményeink alapján elmondható, hogy a tanulók közel fele 15 évesen, vagy annál fiatalabb életkorban kezd nemi életet élni. Ugyan a leggyakrabban alkalmazott fogamzásgátló módszer a kondom volt körükben a legutóbbi aktus során, igen magas azok aránya, akik egyáltalán nem védekeztek. 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

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
