Corona formation in twin-point/plane gaps is experimentally investigated under HVAC. There are many factors affecting such corona formation. The investigated factors are the spacing between the two points, gap length between the twin-point and the plane, ambient temperature, relative humidity, frequency of the applied voltage, and electrode material. In order to study and explain such phenomena, a photographic investigation together with a simultaneous measurement of both the applied voltage and the corona current are also introduced

The Burdur Fethiye fault zone in southwestern Turkey is located in a tectonically active area. According to historical recordings, the region has been destroyed by earthquakes many times. In this region alone, more than 90 earthquakes with magnitudes of more than 5 have occurred since the beginning of the 20th century. Seven of them were recorded with magnitudes between 5.0 and 7.5 in the region between Burdur and Fethiye (October 3, 1914 Burdur: M 7.0, August 7, 1925 Dinar: M 6.0, May 12, 1971 Burdur: M 6.2, April 25, 1957 Fethiye: M 7.1, October 1, 1995 Dinar: M 6.1, December 15, 2000 Aksehir: M 5.9, February 3, 2002 Cay: M 6.0). To determine tectonic characteristics of the region, a network of ten sites was established and GPS measurements were made on this network. After the first year, the network was extended with six new points and additional GPS measurements were made with the financial support of TUBITAK (Scientific and Technical Research Council of Turkey). GPS data were processed using the GAMIT/GLOBK software package. After three years, GPS measurements were processed and tectonic movements of Burdur Fethiye fault zone were observed. Velocity values of tectonic movements, fault plane solutions and the geological structure of the zone show that the zone is active.

Annual fasting during the month of Ramadan is observed in Muslim countries, some of which have widespread HIV infection. We studied treatment adherence and customary practices among 142 fasting ‘FT’ and 101 non-fasting ‘NFT’ patients on anti-retroviral therapy (ART) in Nigeria. Adherence on ART among FT and NFT patients was similar during Ramadan, 96% and 98%, and ever since commencement of ART, 80% and 88%, respectively. FT patients altered their typical daily behaviors by advancing morning and delaying evening doses thereby prolonging dosing intervals, eating heavier meals pre-dawn and on breakfast at sunset (78%), and changing or reducing their sleeping and waking times (40%). This preliminary study suggests that adherence and drug taking frequency appear uncompromised in FT HIV infected patients on ARVs.
