Storytelling: Performance, Presentations and Sacral Communication
Various schools of tale research manifested the relationship of tales of the sacred based on their ideological preconceptions: the relationship between tales and the sacred is refused or accepted. In this article tales are investigated not from the perspective of the possible sacral referent(s) but rather it looks at them as a kind of communicational subsystem that is part of human culture. The focus is on revealing the specific features of sacral communication in the communication system of tales. Sacral communication is a special form of communication in which the elements of the communication model are transformed. The goal of sacral communication is exactly this kind of identity creation. This may be oriented towards creating a personal or a communal self-identity. Among its characteristics we may find the special type of language forms in which the predominance of linguistic elements pushes the sense conveying possibilities more into the background than usual, and those linguistic forms that restructure consciousness become emphasized. In this communication the tale telling is transformed by a language use characteristic of sacral communication (rhythm, repetition and rhetorical forms). Various examples explain that traditional tale telling creates a complex effect related to the visual, auditory, and kinetic senses: a modification and transformation of the self-understanding and self-identity that connect the world of tale telling to sacral communication

Zirconia-Toughened Alumina (ZTA) Nanoceramics with a Gradient Microstructure: A Comparative Study of ZTA Ceramics with Fibrous and Granular Morphology
ZrO2-toughened Al2O3 (ZTA) ceramic composites with a porosity gradient and with improved mechanical properties have a wide range of possible applications. We fabricated nanofibrous and nanogranular Y-ZTA and Ce-ZTA composites with a gradient microstructure by creating a temperature gradient during SPS sintering, with the use of asymmetric graphite tool arrangement (ASY). In this study, we examined the morphology effect of the starting materials on the sintering process and on the final microstructure, as well as the mechanical properties of the composites. A large temperature difference was established for both the granular and fibrous samples fabricated in the ASY configuration, which resulted in gradient porosity along the ceramics bodies: the upper part of the ceramics showed a highly porous fine microstructure, while the opposite side was highly densified. The final microstructure of the composites can be tailored by varying the morphology of the starting ceramics or the graphite configuration. A highly porous skeleton-like structure was formed by sintering fibres in the ASY configuration, whereas the granular precursors resulted in a much less porous composite. The microstructure affected the mechanical properties of the composite. Improved hardness and more than 50% higher compression strength were obtained for the granular Ce-ZTA samples as compared to the fibrous sample. Gradient porosity with fibrous or granular morphology promotes the penetration of bioactive nanosized hydroxyapatite (HAp) into the pore structure. Fibrous ZTA absorbs HAp more effectively due to its higher porosity as well as its bimodal pore structure
Talaj tápanyag- Ă©s toxikus elemtartalom horizontális átrendezĹ‘dĂ©si törvĂ©nyszerűsĂ©geinek vizsgálata mintavĂzgyűjtĹ‘n = Study of horizontal migration tendencies of fertilizer and toxic elements in soils of a catchment area
Kutatásunk során a Velencei-tĂł 14 km2 nagyságĂş vĂzgyűjtĹ‘jĂ©n vĂ©geztĂĽnk vizsgálatokat. Mikro szinten parcellákon lejtĹ‘ menti talajerĂłziĂł modellezĂ©st vĂ©geztĂĽnk az E2D szoftver segĂtsĂ©gĂ©vel, tĂ©rkĂ©pezĂ©ssel feltártuk a csapadĂ©k esemĂ©nyhez kötĹ‘dĹ‘ tĂ©rbeli elemátrendezĹ‘dĂ©si tendenciákat, ĂĽledĂ©kcsapdák kihelyezĂ©sĂ©vel vizsgáltuk az egyes csapadĂ©kesemĂ©nyekhez kötĹ‘dĹ‘en az elemfeldĂşsulást (ER) az erĂłziĂłval mozgĂł szedimentben. Mezo szinten a vĂzgyűjtĹ‘ egĂ©szĂ©n modelleztĂĽk a talajerĂłziĂłt E3D szoftverrel, megszerkesztettĂĽk a kiindulási tápanyag tĂ©rkĂ©peket, majd modelleztĂĽk a vĂzgyűjtĹ‘re a csapadĂ©k esemĂ©nyek hatására bekövetkezĹ‘ tápanyagmozgást. ĂśledĂ©kcsapdás elemzĂ©seink azt mutatják, hogy minden vizsgált paramĂ©ter tekintetĂ©ben a talajban mĂ©rt koncentráciĂłt meghaladĂł a lemosĂłdĂł szedimentben mĂ©rt elemkoncentráciĂł. A szervesanyag tartalom esetĂ©ben ER=2.1-szeres, mĂg a leiszapolhatĂł rĂ©sz esetĂ©ben csupán átlagosan ER=1,2-szoros feldĂşsulás jellemzĹ‘. A mikroelemek közĂĽl a leginkább a Ni (ER=2,1), Zn (ER=1,2) Ă©s a Cu (ER=1,15) dĂşsul. A tápanyag vesztesĂ©g tĂ©rkĂ©peket vizsgálva megállapĂthatĂł, hogy annak tĂ©rbeli alakulását nem a kiindulási tápanyag tĂ©rkĂ©pben fellelhetĹ‘ kĂĽlönbsĂ©gek határozzák meg, azt felĂĽl rajzolják a jellemzĹ‘ erĂłziĂłs viszonyok. A terĂĽletre jellemzĹ‘ átlagos Zn elmozdulás 14,26 mg/m2. Az AL-P2O5 lemosĂłdás fĹ‘kĂ©nt a környezĹ‘ terĂĽleteknĂ©l magasabb P tartalommal rendelkezĹ‘ szántĂłkon jelentĹ‘s. Az átlagos AL-P2O5 kimosĂłdás a vizsgált kĂ©t csapadĂ©k esemĂ©nynĂ©l 5,5 - 15,05 mg/m2. | During our research we carried out examinations on two scales in the catchment area of a Lake Velence. We carried out soil erosion modelling along the slopes with the help of the E2D software, and examined enrichment ratios (ER) in the erosive sediment due to rainfall events by setting up sediment collectors. Taken the whole catchment area into consideration we modelled soil erosion with E3D software, we constructed the initial nutrient maps, and we modelled nutrient transport in the catchment area due to rainfall events. Our analyses of the sediment collectors show that the element concentration measured in the washed-off sediment exceeds the concentration in the soil in case of every studied parameter. The enrichment ratio of the organic matter is ER=2.1, while that of the silt+clay content is ER=1,2 on average. Microelements Ni (ER=2,1), Zn (ER=1,2) and Cu (ER=1,15) enrich most. Studying the nutrient loss maps it can be stated that its spatial change is determined not by the differences in the initial nutrient map, but by erosional conditions. The average Zn change characteristic of the area is 14,26 mg/m2. AL-P2O5 wash-off is significant mainly in arable lands with higher phosphorus content than the surrounding areas. The average AL-P2O5 wash-out during the two studied rainfall events was 5,5 - 15,05 mg/m2
A szöveti hidráció szabályozásának experimentális vizsgálata - különös tekintettel a perinatális időszakra = Experimental studies on the regulation of tissue hydratation with particular reference to the perinatal period
1. A vĂzterek perinatális átrendezĹ‘dĂ©sĂ©nek Ăşj koncepciĂłját dolgoztuk ki. ĂšjszĂĽlött nyulakban Ă©s foetusokban igazoltuk, hogy a kĂĽlönbözĹ‘ mobilitásĂş szöveti vĂzfrakciĂłk aránya az Ă©rĂ©s során sajátosan változnak. Igazoltuk, hogy a foetális/neonatális agy- Ă©s tĂĽdĹ‘szövetben a fizikai vĂzterek átrendezĹ‘dĂ©sĂ©t anyai steroid, terbutalin Ă©s amilorid kezelĂ©se nem befolyásolja. 2. Humán anyagban 14-40 hetes gesztáciĂłs korĂş magzatokban vizsgáltuk az agyszövet-specifikus aquaporin-4 (AQP4) Ă©s aquaporin1 (AQP1) membrán-csatorna fehĂ©rjĂ©k expressziĂłját Ă©s leĂrtuk azok intracellularis elhelyezkedĂ©sĂ©nek Ă©s mennyisĂ©gĂ©nek semi-kvantitatĂv változásait. FelhĂvtuk a figyelmet az AQP-k Ă©lettani Ă©s klinikai jelentĹ‘sĂ©gĂ©re az agy fiziolĂłgiás dehidráciĂłjának folyamatában. 3. Kimutattuk, hogy az angiotenzin konvertálĂł enzim (ACE) DD genotipusa protektĂv hatással bĂr alacsony sĂşlyĂş koraszĂĽlöttekben a keringĂ©si elĂ©gtelensĂ©g kialakulása szempontjábĂłl. 4. Kongentiális szĂvfejlĹ‘dĂ©si rendellenessĂ©ggel szĂĽletett ĂşjszĂĽlöttek vĂ©rmintáinak retrospektĂv analĂzisĂ©vel megállapĂtottuk, hogy a vaszkuláris endotheliális növekedĂ©si faktor (VEGF) gĂ©npolymorfizmusa növeli a szĂvfejlĹ‘dĂ©si rendellenessĂ©gek kialakulásának kockázatát. 5. MegállapĂtottuk, hogy az Ă©retlen vese beszűkĂĽlt koncentrálĂłkĂ©pessĂ©ge az eddigi ismert mechanizmusok melett a vese papilla/medulla magas hialuronsav tartalmával magyarázhatĂł. A szöveti hialuronsav az ADH-mediálta ozmotikus vĂzmozgást gátolja. | 1. A new concept of perinatal redistribution of body fluid compartments has been developed. In fetal/neonatal rabbit pups we demonstrated marked changes in the various physical water compartments which remained unaffected by maternal administration of steroid, terbutaline and amiloride. 2. The developmental changes in aquaporin-1 (AQP1) and AQP4 were investigared in human brain tissue during the period of 14-40 weeks of gestation. We demonstrated the progressive increase of their expression and the pattern of their distribution as the gestation advances. Furthermore, the role of AQP-s in the physiological brain dehydration has been established. 3. Evidences have been provided to indicate the protective effects of ACE DD genotype on the development of circulatory failure in low-birthweight neonates. 4. We have shown that infants born with congenital cardiac malformation have polimorphism for the vascular endothelial growth factor. 5. Indirect evidences have been provided that in addition to the well-known factors, the limited capacity of immature kidney to concentrate urine can be attributed to the high hyaluronic acid content of the renal medulla/papilla since HA limits ADH-mediated osmotic water flo
Egy belső-somogyi fás legelő múltja, jelene és jövője természetvédelmi szempontból
A fás legelĹ‘ az eurĂłpai kultĂşrtáj egyik kiemelten fontos Ă©lĹ‘helytĂpusa, amely iránt pár Ă©vtizedes tájhasználat felhagyást követĹ‘en, a termĂ©szetvĂ©delem Ă©s a mezĹ‘gazdaság rĂ©szĂ©rĹ‘l is elkezdett nĹ‘ni az Ă©rdeklĹ‘dĂ©s. CĂ©lunk egy felhagyott fás legelĹ‘ tájtörtĂ©netĂ©nek, botanikai Ă©rtĂ©keinek Ă©s jövĹ‘beli kezelĂ©si lehetĹ‘sĂ©geinek a feltárása. A vizsgált NyĂresi legelĹ‘t (Pusztakovácsi) a 19. század vĂ©gĂ©tĹ‘l egĂ©szen az 1960-as Ă©vekig közsĂ©gi legelĹ‘kĂ©nt használták, majd a helyi termelĹ‘szövetkezet tulajdonába kerĂĽlt. Ezután a terĂĽlet legeltetĂ©sĂ©t Ă©s tisztĂtását fokozatosan felhagyták. Utoljára 1998-ban legeltettek a terĂĽleten. A felhagyás Ăłta spontán beerdĹ‘sĂĽlĂ©s Ă©s cserjĂ©sedĂ©s indult el a legelĹ‘ nagy rĂ©szĂ©n, emellett egyes rĂ©szeket beerdĹ‘sĂtettek, szántĂłvá alakĂtottak át, az Ă©szaki Ă©s a dĂ©li rĂ©szeket pedig kaszálják. A legelĹ‘n napjainkban nĂ©gy vĂ©dett növĂ©nyfaj fordul elĹ‘, melyeket eredeti nyĂlt Ă©lĹ‘helyĂĽk beerdĹ‘sĂĽlĂ©se Ă©s az özönfajok terjedĂ©se veszĂ©lyeztet. A művelĂ©si ág változtatások nem hoztak gazdasági eredmĂ©nyeket. TermĂ©szetvĂ©delmi Ă©s gazdálkodási szempontbĂłl is a terĂĽlet fás legelĹ‘kĂ©nt valĂł ĂşjbĂłli hasznosĂtása lenne a legmegfelelĹ‘bb. Ennek megvalĂłsĂtását elsĹ‘sorban a bekövetkezett művelĂ©si ág változások akadályozzák, amellett hogy a terĂĽlet tulajdoni viszonyai is megnehezĂtik az egykori egysĂ©ges terĂĽlethasználat visszaállĂtását
