This work reports a first attempt to measure the solar neutrino annual<br />flux modulation due to Earth\'s elliptical orbit with the Borexino detector. Borexino is a real-time calorimetric detector for low energy neutrino spectroscopy located in the underground laboratory of Gran Sasso, Italy. The experiment\'s main focus is the direct measurement of the 7Be solar neutrino flux of all flavors via neutrino-electron scattering in an ultra-pure scintillation liquid. The original goal of this work was to quantify sensitivity of the Borexino detector to a 7% peak-to-peak signal variation over the course of a year and study background stability. A Monte-Carlo simulated sample of the expected variation was prepared in two phases of data acquisition, Phase I that spans from May-2007 to May-2010 and Phase II from October-2011 to September-2012. The data was then fitted in the time domain with a sinusoidal function and analyzed with the Lomb-Scargle fast Fourier transformation in the search for significant periodicities between periods of 0.5 and 1.5 years. The search was performed in the energy window dominated by 7Be, [210; 760] keV, and 60-day bins in the case of the fit and 10-bins for the Lomb-Scargle scan. This work also contains study of the post-purification data of Phase II beyond September-2012 with a prediction for the future sensitivity and justification of the achieved background levels. / Ph.

Three key questions are identified and answered in this paper. Firstly, have the average annual temperatures in the Prince George Region changed in recent years? Secondly, have the seasonal flow rates changed for local waterways? Lastly, have the timing of the annual flood cycles in the Prince George, British Columbia changed? By reviewing data from local weather and hydrological monitoring stations, this paper identifies that the average annual temperature in Prince George, British Columbia has not only increased but also shifted to a pattern of warmer winters and cooler summers. The flow rates for the region were seen to have been altered as well, indicating increased flow rates in the winter and early spring and decreased flow rates in the summer and early fall. The magnitude of flood frequency events such as the 10, 25 and 100 year flood occurrence does not seem to have the increased in recent years.

After the successful evaluation in 2015 we started research and further development of our largescale facilities, in particular the Ion Beam Center (IBC), in the framework of Helmholtz’s Programmeoriented Funding scheme (POF) which coordinates scientific cooperation on a national and international scale. Most of our activities are assigned to the Helmholtz program “From Matter to Materials and Life” within the research area “Matter”, in cooperation with several other German Helmholtz Centers. Our in-house research is performed in three so-called research themes, as depicted in the schematic below. What is missing there for simplicity is a minor part of our activities in the program “Nuclear Waste Management and Safety” within the research area “Energy”. A few highlights which have been published in 2015 are reprinted in this annual report in order to show the variety of the research being performed at the Institute, ranging from self-organized pattern formation during ion erosion or DNA origami patterning, over ferromagnetism in SiC and TiO2 to plasmonics and THz-spectroscopy of III-V semiconductors. A technological highlight published recently is the demonstration of nanometer scale elemental analysis in a Helium ion microscope, making use of a time-of-flight detector that has been developed at the IBC. In addition to these inhouse research highlights, also users of the IBC, in particular of the accelerator mass spectrometry (AMS), succeeded in publishing their research on geomorphology in Nepal in the high-impact journal Science (W. Schwanghart et al., Science 351, 147 (2015)), which demonstrates impressively the added value of transdisciplinary research at the IBC. In order to further develop the IBC, we have started in 2015 the design and construction of our new low energy ion nanoengineering platform which was highly recommended by the POF evaluators. It will consist of two-dimensional materials synthesis and modification, high-resolution ion beam analysis and high-resolution electron beam analysis and will come into full operation in 2019.

The African Crowned Eagle, Stephanoaetus coronatus, is a large raptor with a particularly long breeding cycle, even considering its size (Newton 1979). The incubation period is 49–51 days, the nestling period is 104–115 days and the length of the post-fledging period is contentious and varies considerably within its distribution in Africa (Steyn 1982). In some regions where the bird breeds biennially, this period is up to 350 days (Brown and Amadon 1989, Shultz 2002), whereas in other regions the post-fledging period is shorter as pairs bred annually, even for nine years in succession (Vernon 1984). The reason for this discrepancy has been ascribed to environmental quality and seasonal variability, and differences in the main prey base, densities and mortalities between populations (Newton 1979, Jarvis et al. 1980, Steyn 1982, Vernon 1984, Boshoff et al. 1994, Shultz 2002). Furthermore, it is unclear if the fledglings disperse from the nesting area of their own free will or are evicted by the parents (Brown 1966, Oatley 1970).
