A Theme of Counter-Reformation in Western Art: Mary of Loreto
Bu makalenin konusu, Italyan sanatina ozgu bir tema olarak seckinlesen Loreto Meryem’i betimleri ve bu betim tipinin ortaya cikisi, donemin dinsel ortamiyla iliskisi, ele alinan sahne semasinin gelisimi olusturmaktadir. Loreto Meryem’i, ilk ornekleri bu donemde verilen, Loreto’nun Katolik Kilisesi’nin hac merkezlerine katilmasiyla Italyan ikonografisine ozgu bir temaya donusen ve etkisini Karsi-Reformasyon sureciyle artiran bir betim tipidir. Bunun yani sira Karsi-Reformasyon doneminde Trento Konsili kararlari geregince Katolik inancinin one surdugu Meryem kultu ve bu kultun gelisiminde onemli rol ustlenen Fransisken ve Cizvit tarikatlarinin yaklasimlari ele alinan konular arasindadir. Kutsal Ev’in efsanesine iliskin incelemenin ardindan Nasira’dan Loreto’ya tasinan Ev icin insa edilen Basilica della Santa Casa’nin (Kutsal Ev Bazilikasi) mimarisine deginilmistir. En erken orneklerinden baslayarak Italyan sanatindaki Loreto Meryem’i betimleri ele alinmis ve gosterim bicimi acisindan sahne kaliplari saptanmistir. Karsi-Reformasyon ilkeleri baglaminda Meryem kultunun yukselisi ve Loreto Meryem’i temasinin etkili oldugu donem uzerine odaklanilarak bu temayailiskin orneklere yer verilmistir. Sonuc bolumunde ise, Loreto Meryem’i betimlerinin Italyan sanatindaki ikonografik gelisimi ve Karsi-Reformasyon ilkeleri baglaminda temanin ele alinisi uzerine bir degerlendirme yapilmistir.
Simulation study of high power microwave generation by virtual cathode oscillation in coaxial vircator
Summary form only given, as follows. We have numerically simulated the high power microwave generation by virtual cathode oscillation in a coaxial vircator with 3 dimensional PIC code Magic. It is noted that the coaxial vircator has the advantage of an enhancement of power efficiency and gaining of narrow bandwidth frequency. The study is focused on the design of a diode structure for a coaxial vircator suitable for Chundoong IREB pulser (Max. 600 kV, 85 kA, 60 ns). It consists of a center annular cathode, a cylindrical meshed-anode and a reflector. The simulation results showed that the coaxial vircator can indeed be operated at the selected frequency with the narrow bandwidth and the microwave output power strongly depends on the position and geometry of the reflector. From this simulation results we expect that the maximum microwave output power will be obtained by the reflector of 4 cm in width and also 4 cm in distance away from the IREB, where the resonant frequency of microwave from coaxial vircator is simulated to be 6.577 GHz.
