Under certain geomorphological conditions, sandy sediments supplied to a coast may become trapped in nearshore sedimentary compartments because these are laterally confined by bedload boundaries or convergences. Where sediment supply is small or the shoreface very steep, and accommodation space as a consequence large, the trapping mechanism may be very efficient. The Tsitsikamma coast along the South African south coast is a case in point, the sediment supplied by local rivers over the past 12 ka having been trapped in a nearshore sediment wedge extending at least 5 km offshore. On the basis of high-resolution seismic surveys, the volume of the sediment wedge has been estimated at 1,354×106 m3. As 5% of this volume is considered to have been contributed by bioclastic material of marine origin, the terrestrial input would be 1,286×106 m3. This amounts to an average annual terrestrial sediment input of 0.1072×106 m3. Using a detailed sediment yield map, the modern mean annual sediment supply to the Tsitsikamma coast by local rivers has been estimated at 0.1028×106 m3. Unless coincidental, the remarkable similarity of the two values suggests that the current climatic conditions along the Tsitsikamma coast correspond to the Holocene mean. This conclusion is supported by the currently available climate data for the South African south coast. © 2017 Springer-Verlag Berlin Heidelberg

Proteins: Structure, Function and Bioinformatics | Year: 2015
In this work, we formulate a closed-form solution of the model of a semirigid molecule for the case of fluctuating and reorienting molecular electric dipole moment. We illustrate with numeric calculations the impact of protein domain motions on dielectric spectra using the example of the 128 kDa protein dimer of Enzyme I. We demonstrate that the most drastic effect occurs for situations when the characteristic time of protein domain dynamics is comparable to the time of overall molecular rotational diffusion. We suggest that protein domain motions could be a possible explanation for the high-frequency contribution that accompanies the major relaxation dispersion peak in the dielectric spectra of protein aqueous solutions. We propose that the presented computational methodology could be used for the simultaneous analysis of dielectric spectroscopy and nuclear magnetic resonance data. © 2015 Wiley Periodicals, Inc.

A communication system, apparatus and method thereof are provided. The system includes a connection processing server, an advertisement server, and a communication apparatus. The communication apparatus, which is connected to the connection processing server and the advertisement server, transmits an advertisement request to the advertisement server and receives an advertisement information from the advertisement server, wherein the advertisement information includes an advertisement list and a plurality of advertisement contents corresponding to the advertisement list. When the communication apparatus displays the advertisement list and an operating signal is received by the communication apparatus, the communication apparatus displays one of the advertisement contents corresponding to the operating signal, and transmits a view-ad request to the advertisement server. When the advertisement server receives the view-ad request, the advertisement server transmit an account credit request to the connection processing server to update a account balance corresponding to the communication apparatus.

Methods and systems for managing data items across multiple data services are disclosed. The method includes establishing a first connector with a source data service and a second connector with a destination data service. The method also includes receiving a job implicating data items that are to be transferred to the destination data service. For each item, the method includes determining whether a set of operations needs to be performed on the data item to comply with requirements of the destination data service. When a set of operations needs to be performed, the method includes instantiating an operation pipeline including one or more operators based on the set of operations. The method further includes receiving the data item via the first connector, transforming the data item to a transformed data item using the pipeline, and transmitting the transformed data item to the destination data service via the second connector.
