Configuration of 2-Hydroxyputrescine

Configuration of 2-hydroxyputrescine.

S-( +)-Z-hydroxyputrescine.ZHCl and R-( -)-Z-hydroxyputrescine .ZHCl were synthesized from S-( -)and R-( +)hydroxysuccinamide, respectively. Their specific rotations were determined to be [@” = +3.21 f 0.06” and -3.3” (c = SC/c, H20), respectively. The naturally occurring polyamine isolated from Pseudomonas (Kim) appears to be S-2-hydroxyputrescine since the specific rotation of its dihydrochlo...

2 LoCo : A Logic for Configuration Problems 2 Configuration

In this paper we present the core of LoCo, a logic-based high-level representation language for expressing configuration problems. LoCo shall allow to model these problems in an intuitive and declarative way, the dynamic aspects of configuration notwithstanding. Our logic enforces that configurations contain only finitely many components and reasoning can be reduced to the task of model constru...

2 Network Sensitivity to Geographical Configuration

Gravitational wave astronomy will require the coordinated analysis of data from the global network of gravitational wave observatories. Questions of how to optimally configure the global network arise in this context. We have elsewhere proposed a formalism which is employed here to compare different configurations of the network, using both the coincident network analysis method and the coheren...

Establishing Applicability of SSDs to LHC Tier-2 Hardware Configuration

Solid State Disk technologies are increasingly replacing high-speed hard disks as the storage technology in high-random-I/O environments. There are several potentially I/O bound services within the typical LHC Tier-2 in the back-end, with the trend towards many-core architectures continuing, worker nodes running many single-threaded jobs and storage nodes delivering many simultaneous files can ...
