The synthesis, crystallographic and spectroscopic properties of four divalent isomorphous metal complexes of tetraphenylazadipyrromethene are described.

I agree with Jaakko Hintikka that the so-called “conjunction fallacy” of Kahneman and Tversky is no fallacy. I prefer a different explanation of the mistake made these authors (Levi 1985). Experimental subjects are invited to rank a set of propositions about Linda with respect to how probable, credible or likely they are on the basis of information given about a 31-year Linda. The task is to ra...

Opposite enantiomers of [Ru(phenanthroline)(3)](2+) affect the persistence length of DNA differently, a long speculated effect of helix kinking. Our molecular dynamics simulations confirm a substantial change of duplex secondary structure produced by wedge-intercalation of one but not the other enantiomer. This effect is exploited by several classes of DNA operative proteins.

Auxiliary basis sets for density fitting second-order Moller-Plesset perturbation theory (DF-MP2) have been optimized for use with the triple-zeta nonrelativistic all-electron correlation consistent orbital basis sets, cc-pVTZ-NR and aug-cc-pVTZ-NR, for the 3d elements Sc-Zn. The relative error in using these auxiliary basis sets is found to be around four orders of magnitude smaller than that ...

the interaction between dmso and alkaline earth perchlorates in anhydrous acetonitrile was investigated by ft-ir spectroscopy. a quantitative study was performed to determine the average number of bonded dmso molecules using v (so) and v (c-s) vibrations. changes in coordination numbers were observed both with increasing atomic numbers and the solvent composition. none of the investigated syste...

BACKGROUND Children with developmental coordination disorder (DCD) are often identified by classroom teachers and the identification process relies heavily on teachers' perceptions. The literature would suggest that teachers' perceptions may be influenced by a child's gender, behaviour and the type of motor problem they demonstrate. To date, the influence of these factors on teachers' perceptio...

INTRODUCTION There is substantial evidence to support the relationship between transcription skills (handwriting and spelling) and compositional quality. For children with developmental coordination disorder, handwriting can be particularly challenging. While recent research has aimed to investigate their handwriting difficulties in more detail, the impact of transcription on their compositiona...

INTRODUCTION Quiet eye training (QET) has been shown to be more effective than traditional training (TT) methods for teaching a throw and catch task to typically developing 8-10 yr old children. The current study aimed to apply the technique to children with developmental coordination disorder (DCD). METHOD 30 children with DCD were randomly allocated into TT or QET intervention groups. The T...

BACKGROUND AND PURPOSE Physical therapists' teaching skills often are disregarded in research studies. We examined whether the use of different teaching principles during neuromotor task training was associated with treatment effects. SUBJECTS Nineteen children (mean age=7 years 5 months, range=5-10 years) who had developmental coordination disorder and who performed below the 15th percentile...
