TL;DR: In this paper, the relative conversion line intensities were measured for the 3200 keV M1+(124±24)% E2 transition in 51V, and the experimental screening factor for the M1-ICC is 033±004, which agrees with the ratio of screened and unscreened bound state electron densities near the nucleus (0327).

TL;DR: In this article, the linear bis-indenofluorene 13, 15-dihydro-11 H-diindeno [2, 1-b; 1′, 2′-h] fluorene (X) has been synthetised in 5 steps (overall yield 30%).
Abstract: Starting from cyclohexene and 2, 2′, 4, 4′-tetramethylbiphenyl the linear bis-indenofluorene 13, 15-dihydro-11 H-diindeno [2, 1-b; 1′, 2′-h] fluorene (X) has been synthetised in 5 steps (overall yield 30%). As an intermediate product the 11, 13, 15-trioxo-derivative IX was obtained. By a side way the 13-oxo-derivative of X and the already known monoangular bis-indenofluorene 13, 15-dihydro-5 H-diindeno [1, 2-a; 1′, 2′-h] fluorene (XIX) were also obtained.

TL;DR: In this paper, a new synthesis of 6, 12-dihydro-indeno [1,2b] fluorene (trans-fluorenacene) was recorded.
Abstract: A new synthesis of 6, 12-dihydro-indeno [1,2-b] fluorene (trans-fluorenacene) in 9 steps starting from fluorene (overall yield 24,5%) is recorded. By partial oxidation of the hydrocarbon its 6-oxo derivative is also obtained.

TL;DR: In this paper, Rosenkotter vertritt die Meinung, das die psychoanalytische Theorie in den Eigenarten ihres Gegenstandes keinen Rechtfertigungsgrund fur eine spezifische Methodologie besitzt, die von der Naturwissenschaften sich unterschiede.
Abstract: Der Autor vertritt die Meinung, das die psychoanalytische Theorie in den Eigenarten ihres Gegenstandes keinen Rechtfertigungsgrund fur eine spezifische Methodologie besitzt, die von der der Naturwissenschaften sich unterschiede. Die von Rosenkotter vorgetragenen Argumente zugunsten einer Auffassung der Psychoanalyse als systematisch verallgemeinerter Historie (Habermas) werden unter Ruckgriff auf die vom modernen Positivismus erarbeiteten Kriterien der Wissenschaftlichkeit kritisiert.

TL;DR: In Switzerland, the tertiary sector possesses the same features as the secondary sector: ==================(1)============ ``(======)€ 1.2€ 0.1€ 0.
Abstract: In Switzerland the tertiary sector possesses the same features as the secondary sector: (1) Firstly, a large degree of economic concentration offsets the geographical dispersion of the country. Banking and commercial establishments are numerous but most of the business of the country is conducted by the large organisations (five large banks, a union of consumption co-operatives and a Federation of MIGROS Cooperatives). (2) Secondly, the sphere of business activity goes beyond the national border. Switzerland is the world’sleading exporter of reinsurance policies; Swiss bankers work on an international scale; her transport industry represents a quarter of her world traffic in goods.2
