The short paper introduces the concept of possible branches of double-stranded DNA (later sometimes called palindromes): Certain sequences of nucleotides may be followed, after a short unpaired stretch, by a complementary sequence in reversed order, such that each DNA strand can fold back on itself, and the DNA assumes a cruciform or tree-like structure. This is postulated to interact with regulatory proteins.
The climate change debate has increased the need for knowledge on both long- and short-term regional environmental changes. In general, these changes may often be a product of multiple causes, which complicates the separation of single driving forces. In this review we focus on current water budget changes in Germany’s capital region, Berlin-Brandenburg, over the last 30 years. Available studies from a variety of disciplines (e.g. hydrology, water engineering, landscape ecology, nature conservation) were analysed in order to (1) identify both local and regional hydrological changes, (2) reveal their potential causes, and (3) discuss responses of ecosystems and society. These studies show that the Berlin-Brandenburg region is widely characterised by decreasing groundwater recharge, leading to decreasing groundwater and lake levels as well as decreasing fluvial discharge. These trends result both from complex, regional human impacts (e.g. long-term effects of hydro-melioration and changes in forest composition) and more general climate warming. The observed and assumed (future) changes of the regional water balance have been creating, and will continue to create, multifaceted impacts on existing ecosystems and society (e.g. wetland drying, decrease of biodiversity, decrease of productivity of grasslands and forests, increasing conflicts of interests). Several efforts to respond to the regional water deficit problem have already been undertaken, comprising for instance land-use optimisation, wetland restoration measures and the reestablishment of mixed deciduous forests. In general, however, the reviewed regional material on this topic reveals that the number and complexity of empirical studies are still poor. Thus, for both the identification and the explanation of current water balance changes and their effects, as well as for development and implementation of adaptive strategies, further multidisciplinary research efforts at different scales, including interregional comparisons, are required. Furthermore, both the observation of hydrological changes and the evaluation of adaptive and mitigative responses require at least continuous or, even better, extended monitoring efforts.
This special issue of DIE ERDE presents selected key topics discussed within the BBAW working group, including work by group members and invited external researchers, containing nine articles highlighting “Regional Water Challenges” resulting from different kinds of environmental and social changes. We aim to present the complexity of interaction between changes and responses. While the first four articles focus on describing climatic and hydrological changes and their causes, the following five articles focus more on possible mitigation and adaptation measures.
Für Schleiermacher ist Religion keine pädagogisch nützliche Mischung von Metaphysik und Moral, sondern eine eigene Dimension des Menschseins, Anschauung des Universums, Sinn und Geschmack fürs Unendliche; die von der Aufklärung favorisierte „natürliche Religion“ der allgemeinen, übergeschichtlichen Vernunftwahrheiten sei bloß eine Totgeburt, jede wirkliche, lebendige Religion dagegen eine unableitbare geschichtliche Individualität. Im Christentum sei Jesus Christus die Zentralgestalt, der Vermittler und Versöhner des Zwiespalts zwischen Endlichem und Unendlichem, an dem sich alle Religion abarbeite. Im Laufe seiner Entwicklung strebe das Christentum immer mehr zu Sozialgestalten ohne Hierarchie zwischen Priestern und Laien; in der Vollendung (den aber selbst der Protestantismus noch nicht erreicht habe) würden alle „von Gott gelehrt“ sein (Johannes 6,45).
Der theologische Rationalismus war die letzte Gestalt der Aufklärungstheologie; seine Blütezeit erlebte er gleichzeitig und in Konkurrenz mit der u.a. von Schelling geprägten spekulativen Richtung und mit der teils mehr biblizistischen, teils mehr konfessionellen Theologie der Erweckung. Kennzeichen des Rationalismus war einerseits eine verstärkte historisch-kritische Quellenforschung, andererseits das Bemühen, Lehre und Praxis soweit möglich auf das auszurichten, was jenseits geschichtlicher Autoritäten der allgemeinen menschlichen Vernunft plausibel sei: die Existenz Gottes, die Unsterblichkeit der Seele und die Pflicht zu tugendhaftem Leben. Seit etwa 1840 verfiel der Rationalismus.

With the present report the Berlin-Brandenburg Academy of Sciences and Humanities wants to draw attention to the results of one of its interdisciplinary projects, which are published elsewhere in more detail. The authors believe that their particular approach to the subject of "waste energy recovery", in combination with an interdisciplinary perspective, suggests a new way of discussing energy problems that has the potential to lead to qualified statements...
We expose analogies between turbulence in a fluid heated from below (Rayleigh-Bénard (RB) flow) and shear flows: The unifying theory for RB flow (S.Grossmann and D.Lohse, J.Fluid Mech. 407, 27-56 (2000) and subsequent refinements) can be extended to the flow between rotating cylinders (Taylor-Couette flow) and pipe flow. We identify wind dissipation rates and momentum fluxes that are analogous to the dissipation rate and heat flux in RB flow. The proposed unifying description for the three cases is consistent with the experimental data.
The present study explores whether regional water resources can be used more efficiently by Brandenburg’s farming systems. A description of agriculture in Brandenburg today is followed by a systematic analysis of measures to raise the water efficiency. Brandenburg’s agricultural systems are divided into three sections: soil, plant production and livestock farming. Within these sections measures to increase water efficiency are listed and analysed with reference to five objective criteria for raising water use efficiency. In view of the complexity of farming systems in Brandenburg, general measures to raise water use efficiency could not be derived. Site-specific tillage practices and crop patterns adjusted to recent weather conditions may reflect the specific diversity of Brandenburg more efficiently.
Alexander von Humboldt’s maps, graphs and illustrations contain a great deal of detail, but in the available rare editions they are hardly visible to the naked eye. In many editions they have been reduced. In a digital library, they will become accessible in their entirety, and Internet technology will reproduce them in a form that overcomes the limitations of the original printing. The user will be able to enlarge the images and see details that might have been overlooked in the past. The Humboldt’s digital library will adhere to the standards for digital libraries established by the Open Archives Initiative (OAI) and the tools EPRINTS and DSPACE to provide the Web services and determine the most effective way to establish dynamic linking and knowledge based searching of information within the archive.
Historic parks and gardens survive in many places with some sites still in use but others abandoned long ago and now given over to other purposes. Accurate repair and reliable reconstruction depend upon archaeological information which is particularly vulnerable to the effects of climate change. The impairment and loss of such detail threaten historical integrity. This means that we must monitor changes and develop suitable mitigation.
Global climate change and aspects of regional climate change in the Berlin-Brandenburg region
(2011)
To obtain an estimate of the average temperature of the northern hemisphere during the last 1200 years, proxy data have been merged with instrumental recordings. These instrumental measurements are, with a few exceptions, only available for the recent 150 years. In the city of Berlin the temperature has been recorded since as early as 1701. However, during the first 150 years the measurements were problematic as location, measurement procedure and instruments changed frequently and without proper documentation. From 1847 onwards observations became more reliable once the Royal Prussian Meteorological Institute had been established. For the last 100 years temperature and precipitation measurements have been performed in parallel at Berlin-Dahlem and Potsdam. The datasets recorded in the city of Berlin and in Berlin-Dahlem have been merged to obtain a record of more than 300 years. It indicates that the temperature of Berlin has risen by 1.04°C during the last 100 years after correcting for the urbanisation effect. In the same period, the total number of frost days has significantly decreased by almost 17 days, and the number of summer days has significantly increased by about 12 days. Annual mean precipitation has hardly changed (decrease less than 0.2 %) during the last century. However, rainfall has decreased by about 4 % in summer and increased by 3 % in winter. All precipitation changes are below the 95 % ignificance level. Model projections indicate that warming will continue which means that Berlin-Brandenburg will experience a temperature rise of about 3-3.5°C by the end of this century for the IPCC scenario A1B. For the same scenario precipitation is expected to increase by 10-20 % in winter and to decrease by 10-30 % in summer: The seasonal precipitation changes compensate each other resulting in an almost unchanged annual mean.
