The Influence of Solvent Reorganization on Organocatalytic Reactions
(2021-04-07)
In the last decades N-heterocyclic carbenes have shown a certain potential as organocatalysts. In addition to the formation of regio- and stereoselective C-C coupling reactions, their scope of application includes the ...
Applying Disaster Risk Governance in Dynamic Environments: Case study Rio de Janeiro State, Brazil
(2021-05-17)
Between 1980 and 2015, around 1.6 billion people were killed in meteorological, geophysical, hydrological or climatological disasters. Future annual losses are estimated to reach US4 billion in the built environment alone. ...
Characterization of the hyperpolarization-activated, highly-selective proton channel HCNL1 found in the sperm of the zebrafish Danio rerio
(2021-04-29)
Zebrafish are external fertilizers and release their gametes into the surrounding water. Yet, the freshwater environment with its low osmolarity poses a challenge for the gametes. Given these unique ion conditions, it seems ......

(2020-07-24)
North Sulawesi province is one of the most potential areas in terms of natural marine resources. In North Sulawesi there are many interesting tourist places with high marine biodiversity and many objects are currently under ...
Targeted Fast Radio Burst Searches with the Efflesberg 100-m Radio Telescope
(2021-03-24)
Fast radio bursts (FRBs) are bright, energetic, millisecond duration radio bursts of extragalactic origin. The source of FRBs still remains an open problem. Since the discovery of FRBs in 2007, over 100 FRBs have been ...
Molekulare Mechanismen der prometastatischen Tumorzell-Thrombozyten-Interaktionen während der hämatogenen Metastasierung und ihre Inhibition durch Antikoagulantien
(2020-02-04)
In dieser Arbeit wurden die Mechanismen der prometastatischen Interaktionen zwischen Thrombozyten und Tumorzellen während der hämatogenen Metastasierung betrachtet und untersucht, ob Antikoagulantien die hämatogene ...
Talentierte symbiontische Naturstoffproduzenten als Quelle neuer Wirkstoffe
(2020-03-03)
Zunehmende Resistenzen und gleichzeitig sinkende Zahlen neu zugelassener Antibiotika lassen den Bedarf an neuen antibiotischen Wirkstoffen steigen. Aber auch in anderen medizinischen Bereichen wie z. B. der Onkologie ist ...
Mining and small-scale farming in the Andes: Socio-environmental roots of land-use conflict
(2020-04-08)
The Peruvian Andes are one of the most important water sources for the country. Therefore, their exploitation might pose critical threats for local farming activities, national economy, and water quantity and quality. At ...
