A Kárpát-medence jelenkori és paleorengéseinek komplex vizsgálata = Integrated study of recent earthquakes and paleoerthquakes in the Carpathian basin
Három feladatot jelöltĂĽnk meg, amelyeket a 4 Ă©ves kutatás folyamán meg kĂvánunk oldani: 1. Kárpát-medencĂ©ben Ă©s a hozzá hasonlĂł földtani felĂ©pĂtĂ©sű tĂ©rsĂ©gekben keletkezett földrengĂ©sek lehetsĂ©ges okainak tisztázása. 2. TörtĂ©nelmi Ă©s paleorengĂ©sekre kutatása. 3. A földrengĂ©sekre vonatkozĂł ismeretanyag rendszerezĂ©se Ă©s számĂtĂłgĂ©pes adatbázisának elkĂ©szĂtĂ©se. RĂ©szletesebben: 1. Ă–sszegyűjtöttĂĽk Ă©s tĂ©rinformatikai rendszerbe illesztettĂĽk a földrengĂ©sekkel kapcsolatba hozhatĂł geolĂłgiai Ă©s geofizikai tĂ©rkĂ©pi adatokat. TĂ©rinformatikai elemzĂ©seket vĂ©getĂĽnk a rendszer rĂ©tegei között, mely alapján bebizonyosodott, hogy a magyarországi rengĂ©sek összessĂ©ge nem magyarázhatĂł ismert tektonikus szerkezetek mentĂ©n bekövetkezĹ‘ elmozdulásokkal. 2. A Baradla-barlangban találhatĂł, 5.1 m magas sztalagmitot az elmĂşlt 100 e Ă©v folyamán 1.14 m/s2-nĂ©l nagyobb horizontális gyorsulás nem gerjesztette. Ezt a horizontális gyorsulásĂ©rtĂ©ket figyelembe kell venni minden, erre a terĂĽletre vonatkozĂł földrengĂ©sveszĂ©lyeztetettsĂ©gi számĂtásnál. PaleorengĂ©s-vizsgálatainkat kiterjesztettĂĽk Bulgáriában találhatĂł cseppkövekre is. 3. ElkĂ©szĂĽlt a törtĂ©nelmi földrengĂ©sek Microsoft Access adatbázisa. Az adatbázis nyolc csatlakozĂł táblázatot tartalmaz. Az adatbázis kĂ©rdĹ‘Ăveinek formátuma az adatbevitelt egyszerűvĂ© teszi. | Comprehensive investigation of recent and paleoearthquake occurred in the Carpathian Basin 1. Examination the geological structures of the potential earthquake sources: A Geoinformation System (GIS) has come into existence in order to investigate the geological and geophysical surroundings of earth tremors applying ArcView 3.2 software. Analyses between different layers of the GIS were carried out. 2. Research of kinetic behaviours of stalagmites exited by horizontal acceleration. Determination of largest paleoearthquake occurred during the lifetime of investigated speleothems: From the parameters of not damaged speleothems (in the HajnĂłczy and Baradla caves in Hungary) can be determine the upper limit of peak horizontal acceleration generated by paleoearthquakes during their formation. In the laboratory the velocity of elastic waves, density and failure tensile stress of speleothem samples have been determined. The fundamental frequency and damping of speleothems have been measured in cavity. We took samples from dripstones of 5.1 m heigth in Baradla cave and determined their age. It was established that these speleothems were not excited with a horizontal acceleration more than 1.14 m/s2 during the last 100 000 years. 3. Database of historical earthquakes occurred in Hungary: The aim of this work was the systematisation of our knowledge about the historical earthquakes of Hungary and to introduce them into a database
200 more puzzling physics problems: with hints and solutions
Like its predecessor, 200 Puzzling Physics Problems, this book is aimed at strengthening students' grasp of the laws of physics by applying them to situations that are practical, and to problems that yield more easily to intuitive insight than to brute-force methods and complex mathematics. The problems are chosen almost exclusively from classical, non-quantum physics, but are no easier for that. They are intriguingly posed in accessible non-technical language, and require readers to select an appropriate analysis framework and decide which branches of physics are involved. The general level of sophistication needed is that of the exceptional school student, the good undergraduate, or the competent graduate student; some physics professors may find some of the more difficult questions challenging. By contrast, the mathematical demands are relatively minimal, and seldom go beyond elementary calculus. This further book of physics problems is not only instructive and challenging, but also enjoyable
