Analysis of Aiming with Tools: Proprioception [PDF]

open access: yesProceedings of the Human Factors and Ergonomics Society Annual Meeting, 2003
One of the major areas of interest in the field of ergonomics is the design of hand tools. Though considerable research has produced more user-friendly tools, there has been some reluctance to use them for some tasks. It is hypothesized that this reluctance on the part of the user may be partly due to the reduction of accuracy while using those ...

Intra-/Intermolecular Bifurcated Chalcogen Bonding in Crystal Structure of Thiazole/Thiadiazole Derived Binuclear (Diaminocarbene)PdII Complexes

open access: yesCrystals, 2018
The coupling of cis-[PdCl2(CNXyl)2] (Xyl = 2,6-Me2C6H3) with 4-phenylthiazol-2-amine in molar ratio 2:3 at RT in CH2Cl2 leads to binuclear (diaminocarbene)PdII complex 3c. The complex was characterized by HRESI+-MS, 1H NMR spectroscopy, and its structure
