a number of complexes in the series (cu ll'),, where l = [(ch,),c-co-ch-coc( ch,),]-i and l'= 3-(me) c6h,0-, 2,6-(di-me)c6h30-, 4-(oh)c6h?o-, 3- (f) c6h,0-, 4-(br)c6h40-a, nd 3,s-(dl-me)c6h30h- ave been prepared and theu magnetic and optical properties determined. in chloroform, the complexes exhibit two bands in the visible and near uv regions. all complexes show room temperature mag...

Traditional industrial applications involve robots with limited mobility. Consequently, interaction (e.g. manipulation) was treated separately from whole-body posture (e.g. balancing), assuming the robot firmly connected to the ground. Foreseen applications involve robots with augmented autonomy and physicalmobility.Within this novel context, physical interaction influences stability and balanc...

The planning fallacy, or tendency to underestimate how long a task will take to complete, is a robust phenomenon. Although several explanations have been oVered (e.g., ignoring underestimations made in the past), we hypothesized that self-presentation concerns may also contribute to the bias, and that this eVect may be exacerbated by a previous failure to complete a task on time. Half of our sa...

introduction: working in the complex and ever changing healthcare settings forces the nurses and nursing students to be equipped with lifelong learning skills. one of the lifelong learning skills is self-directed learning. this study aimed to explore the m.sc. nursing students’ self-directed learning activities. methods: a qualitative design using conventional content analysis approach was used...

Abstract The release of neodymium (Nd) from particles along continental margins may contribute to losses in the global Nd budget. Changjiang River, which carries a heavy load total suspended matter, empties into East China Sea, and strong particulate–seawater interaction process occurs salinity gradient. In low-salinity region ( S < 2.0), removal dissolved rare earth elements (dREEs) occurs,...

We present analytic expressions that approximate the behavior of the spacetime of a collapsing spherically symmetric scalar eld in the critical regime rst discovered by Choptuik. We nd that the critical region of spacetime can usefully be divided into a \quiescent" region and an \oscillatory" region, and a moving \transition edge" that separates the two regions. We nd that in each region the cr...

In many real-world multiagent applications such as distributed sensor nets, a network of agents is formed based on each agent’s limited interactions with a small number of neighbors. While distributed POMDPs capture the real-world uncertainty in multiagent domains, they fail to exploit such locality of interaction. Distributed constraint optimization (DCOP) captures the locality of interaction ...

We determine the physical parameters (magnetic eld and Doppler factor) of the homogeneous synchrotron self-Compton model allowed by the observed X{ray to gamma-ray spectra and variability of Markarian 501 during the 15{16 April 1997 aring activity. We nd that, for 20 minute variability, a magnetic eld of 0.2 G and a Doppler factor of 20 could t these observations. We take account of photon-phot...
