Die priesterskap van die gelowiges soos Calvyn dit gesien het

The priesthood of all believers as seen by CalvinThe Lutheran thesis of the priesthood of all believers was also taken over by John Calvin. The position of this thesis in Calvin’s theology is examined and it is shownthat Calvin does not treat this thesis as a separate statement. A short introduction is given of the main points Calvin explores when he discusses the meaning of the thesis. In the end it is shown that Calvin developed the thesis of the universal priesthood in such a low-key form to preserve the order in the Church and the prime position of the preaching of the gospel

Die betekenis van Abraham Kuyper (1837-1920) vir Suid-Afrika op kerkhistoriese en kerkregtelike gebied

The influence of Abraham Kuyper (1837—1920) on South Africa in the spheres of Church History and Church PolityA short biography of Kuyper is followed by an attempt to qualify him as a typical theologian of the 19th century, as leader of the Doleantie-movement in the Dutch church and as a man of many parts. His personal contact with South Africa is traced, as well as his direct and indirect influence in the South African churches. It is interesting to note that the influence of Kuyper's theology in the Gereformeerde Kerke in Suid-Afrika was largely initiated by JD du Toit while his father, SJ du Toit, introduced Kuyper's theology in the Nederduitse Gereformeerde Kerk. Subsequently it was mainly the influence of the VU (Bavinck and Rutgers) which prevailed in the abovementioned churches

Church history in our theological training; 1917-1956After a short summary of the history of the founding of the Theological Faculty at the old Transvaal University College, attention is given to the Department of ChurchHistory. During the years 1921-1956 professor S P Engelbrecht built up this Department. Attention is given to his work as Church historian, his theologicalposition is discussed and the result of his labours is given

A transiting planet among 23 new near-threshold candidates from the OGLE survey - OGLE-TR-182

By re-processing the data of the second season of the OGLE survey for planetary transits and adding new mesurements on the same fields gathered in subsequent years with the OGLE telescope, we have identified 23 new transit candidates, recorded as OGLE-TR-178 to OGLE-TR-200. We studied the nature of these objects with the FLAMES/UVES multi-fiber spectrograph on the VLT. One of the candidates, OGLE-TR-182, was confirmed as a transiting gas giant planet on a 4-day orbit. We characterised it with further observations using the FORS1 camera and UVES spectrograph on the VLT. OGLE-TR-182b is a typical ``hot Jupiter'' with an orbital period of 3.98 days, a mass of 1.01 +- 0.15 MJup and a radius of 1.13 (+0.24-0.08) RJup. Confirming this transiting planet required a large investment in telescope time with the best instruments available, and we comment on the difficulty of the confirmation process for transiting planets in the OGLE survey. We delienate the zone were confirmation is difficult or impossible, and discuss the implications for the Corot space mission in its quest for transiting telluric planets.Comment: 7 pages, submitted to Astronomy and Astrophysic

Entropy, fidelity, and double orthogonality for resonance states in two-electron quantum dots

Resonance states of a two-electron quantum dot are studied using a variational expansion with both real basis-set functions and complex scaling methods. The two-electron entanglement (linear entropy) is calculated as a function of the electron repulsion at both sides of the critical value, where the ground (bound) state becomes a resonance (unbound) state. The linear entropy and fidelity and double orthogonality functions are compared as methods for the determination of the real part of the energy of a resonance. The complex linear entropy of a resonance state is introduced using complex scaling formalism

The spin-orbit angle of the transiting hot jupiter CoRoT-1b

We measure the angle between the planetary orbit and the stellar rotation axis in the transiting planetary system CoRoT-1, with new HIRES/Keck and FORS/VLT high-accuracy photometry. The data indicate a highly tilted system, with a projected spin-orbit angle lambda = 77 +- 11 degrees. Systematic uncertainties in the radial velocity data could cause the actual errors to be larger by an unknown amount, and this result needs to be confirmed with further high-accuracy spectroscopic transit measurements. Spin-orbit alignment has now been measured in a dozen extra-solar planetary systems, and several show strong misalignment. The first three misaligned planets were all much more massive than Jupiter and followed eccentric orbits. CoRoT-1, however, is a jovian-mass close-in planet on a circular orbit. If its strong misalignment is confirmed, it would break this pattern. The high occurence of misaligned systems for several types of planets and orbits favours planet-planet scattering as a mechanism to bring gas giants on very close orbits.Comment: to appear in in MNRAS letters [5 pages
