side weirs are flow diversion devices that are widely used in irrigation, drainage and urban sewage systems. the present study focuses on the investigation of the effect of oblique side weirs on the discharge coefficient of a side weir under subcritical flow condition in rectangular channels. in this study 106 laboratory tests were conducted and the results were analyzed to find out the influen...

Many organizations today are turning towards the contemporary concept of Cloud Computing, which entails the transfer of their applications (processing both sensitive and non-sensitive data) into online repositories or clouds. Encryption schemes based on homomorphic functions can provide the technology required to protect the confidentiality of this data. Their limitation, however, lies in their...

In a fingerprinting scheme a distributor places marks in each copy of a digital object. Placing different marks in different copies, uniquely identifies the recipient of each copy, and therefore allows to trace the source of an unauthorized redistribution. A widely used approach to the fingerprinting problem is the use of error correcting codes with a suitable minimum distance. With this approa...

We have developed a minimally-perturbing strategy that enables labeling and subcellular visualization of endogenous dendritic receptors on live, wild-type neurons. Specifically, calcium-permeable non-NMDA glutamate receptors expressed in hippocampal neurons can be targeted with this novel synthetic tri-functional molecule. This ligand-directed probe was targeted towards AMPA receptors and bears...

Peramivir is an effective anti-influenza drug in the clinical treatment of influenza, but its efficacy toward the H275Y mutant is reduced. The previously reported cocrystal structures of inhibitors in the mutant neuraminidase (NA) suggest that the hydrophobic side chain should be at the origin of reduced binding affinity. In contrast, zanamivir having a hydrophilic glycerol side chain still pos...

The role of vitamin A and its metabolites in the life processes starting with the historical background and its up to date information is discussed in the introduction. Also the role of 11Z-retinal in vision and retinoic acid in the biological processes is elucidated. The essential role of isotopically enriched systems in the progress of vision research, nutrition research etc. is discussed. In...

There is a graph reduction system so that every optimal 1planar graph can be reduced to an irreducible extended wheel graph, provided the reductions are applied such that the given graph class is preserved. A graph is optimal 1-planar if it can be drawn in the plane with at most one crossing per edge and is optimal if it has the maximum of 4n− 8 edges. We show that the reduction system is conte...
