Rainfall Prediction with AMSR–E Soil Moisture Products Using SM2RAIN and Nonlinear Autoregressive Networks with Exogenous Input (NARX) for Poorly Gauged Basins: Application to the Karkheh River Basin, Iran
(2018-07-23)
Accurate estimates of daily rainfall are essential for understanding and modeling the physical processes involved in the interaction between the land surface and the atmosphere. In this study, daily satellite soil moisture observations from the Advanced Microwave Scanning Radiometer–Earth Observing System (AMSR–E) generated by implementing the standard National Aeronautics and Space Administration (NASA) algorithm are employed for estimating rainfall, firstly, through the use of recently developed approach, SM2RAIN ...

Extreme Ultraviolet to Visible Dispersed Single Photon Detection for Highly Sensitive Sensing of Fundamental Processes in Diverse Samples
(2018-05-23)
The detection of a single photon is the most sensitive method for sensing of photon emission. A common technique for single photon detection uses microchannel plate arrays combined with photocathodes and position sensitive anodes. Here, we report on the combination of such detectors with grating diffraction spectrometers, constituting a low-noise wavelength resolving photon spectroscopy apparatus with versatile applicability. We recapitulate the operation principle of such detectors and present the details of the ...

A Paradigm Shift in Water Quality Governance in a Transitional Context: A Critical Study about the Empowerment of Local Governance in Georgia
(2018-01-01)
The management of water quality is an important part of natural resource governance. Assurance of water quality therefore requires formulation of the regulatory framework and institutional process. Water quality-related problems and their management are mainly recognized as local responsibilities in Integrated Water Resources Management (IWRM). The politics of environmental policy-making should consider the political economic dynamics and socio-ecological patterns. Decentralization by providing more power to the local ...

Nutrition Transition and Traditional Food Cultural Changes in Sri Lanka during Colonization and Post-Colonization
(2018-07-13)
Sri Lanka was a colony of the Portuguese, Dutch, and British. The simplification of Sri Lankan food culture can be seen most clearly today, including how the diet has been changed in the last 400 years since the colonial occupation began. Therefore, greater efforts must be made to uncover the colonial forces that have undermined food security and health in Sri Lanka. Also traditional eating habits, which are associated with countless health benefits, have been gradually replaced by the globalized food system of ...

Sustainability Tensions in Supply Chains: A Case Study of Paradoxes and Their Management
(2018-02-06)
The comprehensive coverage of sustainability issues in a supply chain incurs goal conflicts—i.e., sustainability tensions—and is often limited by market characteristics, such as the availability of sustainable materials and services. While the mainstream business is prioritizing economic goals, a number of entrepreneurs are trying to move forward to more sustainable business practices for their own company and their supply chain. Fairphone represents such a case in the electronics industry, which is openly communicating ...

Der Weg der Erkenntnis
(2018-08)
Das Leben des Menschen stellt ein unaufhörliches Streben nach Glück dar, sodass sich jede einzelne Handlung mit diesem ultimativen Ziel verknüpfen lässt. Die Wege, die zur Erreichung des Glücks beschritten werden, sind dabei sehr unterschiedlich, führen allerdings nicht immer zum gewünschten Ziel. Der Weg der Erkenntnis, vor allem der Selbsterkenntnis, stellt jedoch nach der hier vertretenen Auffassung den einzigen Weg zum unbeschränkten Glück dar.
Zahlreiche Theologen und Philosophen teilen diese Erkenntnis und ...

Requirement of the Dynein-Adaptor Spindly for Mitotic and Post-Mitotic Functions in Drosophila
(2018-03-30)
Spindly was originally identified as a specific regulator of Dynein activity at the kinetochore. In early prometaphase, Spindly recruits the Dynein/Dynactin complex, promoting the establishment of stable kinetochore-microtubule interactions and progression into anaphase. While details of Spindly function in mitosis have been worked out in cultured human cells and in the C. elegans zygote, the function of Spindly within the context of an organism has not yet been addressed. Here, we present loss- and gain-of-function ...

Exploring the Supply-Demand-Discrepancy of Sustainable Financial Products in Germany from a Financial Advisor’s Point of View
(2018-03-23)
Although retail investors’ interest in sustainable investment is constantly increasing, German credit unions and co-operative banks offer few sustainable financial products. The purpose of the study is to explore the current gap between supply and demand of sustainable financial investments in German retail banking from a financial advisor’s point of view. We use qualitative analysis of interviews with financial advisors based on a Grounded Theory approach with the aim to identify the key causation in the cause-effect ...

Protein Phosphatase Sit4 Affects Lipid Droplet Synthesis and Soraphen A Resistance Independent of Its Role in Regulating Elongator Dependent tRNA Modification
(2018-07-11)
The protein phosphatase Sit4 has been shown to be required for lipogenesis and resistance against the acetyl-CoA carboxylase inhibitor soraphen A. Since Sit4 is also required for biosynthesis of Elongator dependent tRNA modifications such as 5-methoxycarbonylmethyluridine (mcm5U), we investigated the relevance of tRNA modifications in lipogenesis and soraphen A response. While sit4 and Elongator (elp3) mutants copy defects in mcm5U formation and stress sensitivity, they do not share soraphen A sensitivity and low ...

Donor-stabilisierte Bisphosphanyl-Tetrylene
(2018-09)
Gegenstand dieser Arbeit war die Untersuchung der Darstellbarkeit Bisphosphanyl-substituierter, schwerer Tetrylene mit 1,1‘-Ferrocenylenrückgrat war. Die Synthese freier, stabiler Bisphosphanyl-Tetrylene gelang aufgrund sterischer und elektronischer Gründe nicht, jedoch konnten NHC-stabilisierte Addukte (Si, Sn, Pb), intermolekular stabilisierte, dimere Donor-Akzeptor Addukte (Sn, Pb) und intramolekular stabilisierte Donor-Akzeptor-Addukte (Pb) isoliert, charakterisiert und deren Reaktionsverhalten untersucht werden.
