The structures of the quinoline adduct with bis(diethyldithiophosphinato)nickel(II) and the 1,10-phenanthroline and 2,9-dimethyl-1,10-phenanthroline adducts with bis(0,0 '-dimethyldithiophosphato)nickel(II) have been determined by single-crystal X-ray techniques. The nickel atom is hexacoordinated in the 1,10-phenanthroline adduct and pentacoordinated in the quinoline adduct as well as in the 2,9-dimethyl-l, 10-phenanthroline adduct. These results suggest that pentacoordinated mixed-ligand complexes of nickel(II) can be obtained by the addition of an appropriate ligand, which may be either monodentate or bidentate, to the planar nickel(II) dithiophosphates or dithiophosphinates.

The film thickness decay of grease lubricated bearings is determined by a loss of lubricant from the bearing. One of these loss mechanisms is base oil evaporation. In this paper, a model is presented for evaporation where the volatiles leave the bearing by breathing. The model is applied to a typical drive cycle where the temperature is varied in time. With the model, the impact of the volatility of base oils and quality of sealing on the evaporation losses can be quantified.

Aim:The aim of this study was to evaluate and compare the values of Steiner's cephalometric analysis using Nemoceph and Foxit PDF Reader. No significant difference between the two methods will result in that Foxit PDF Reader can be used as a cost-effective alternative. Materials and methods: This study was conducted on 100 digital lateral cephalograms taken from the same machine. The samples were collected by nonprobability convenience sampling procedures. These images were analyzed for Steiner's cephalometric analysis using two software packages. Results: The skeletal and dental values showed no statistically significant difference in the majority, except for the L1-NA (linear) and L1-NB (linear). Conclusion:Results showed that there is a high agreement between the two methods. Clinical significance: This article provides a simple and cost-effective method of onscreen cephalometric analysis. This technique uses the inbuilt measurement tools in the tool bar of our daily use software. The method can be used independently anywhere without any internet connection and software subscription.
