Nurses' Practice Environment and Their Job Satisfaction: A Study on Nurses Caring for Older Adults in Shanghai.

Aim: To examine the job satisfaction of nurses who are caring for older adults in healthcare settings in Shanghai, and to explore the underlying factors in order to explain and predict nurses' job satisfaction.

Background: China has the largest elderly population in the world, and its population is aging rapidly. Studies on job satisfaction of nurses providing care for the elderly in China can help to identify problem areas and develop strategies for the improvement of nurses' working conditions.

The major factors influencing the formation of sediments in reconstituted green tea infusion.

The effects of Ca(2+), caffeine and polyphenols on the formation of reversible tea sediments (RTS) and irreversible tea sediments (IRS) in green tea infusion were studied. Adding Ca(2+) (2 mmol/l) was found to increase the formation of RTS by 8% and IRS by 92%, while adding chelating ions of Na2EDTA significantly decreased the amount of RTS by 14.6%, but not the amount of IRS.

[Simultaneous determination of alendronate, pamidronate, ibandronate and risedronate using ion chromatography with integrated pulsed amperometric detection].

A method for the simultaneous determination of alendronate, pamidronate, ibandronate and risedronate using ion chromatography with integrated pulsed amperometric detection (IPAD) has been developed. The electrochemical behavior showed the catalytic currents of these bisphosphonates are based on the oxidation of amines in their structures. Because the bisphosphonates are polar compounds and present as anions under alkaline condition, therefore, they can be separated by anion exchange chromatography.

(E)-Methyl 3-(3,5-dibromo-2-hy-droxy-benzyl-idene)carbazate.

The title compound, C(9)H(8)Br(2)N(2)O(3), crystallizes with two very similar independent mol-ecules in the asymmetric unit, each of which adopts a trans configuration with respect to the C=N bond. Intra-molecular O-H⋯N hydrogen bonds are observed in each independent mol-ecule. In the crystal structure, mol-ecules are linked into chains propagating along [010] by N-H⋯O and C-H⋯O hydrogen bonds.

N'-(2-Meth-oxy-benzyl-idene)aceto-hydrazide.

In the title mol-ecule, C(10)H(12)N(2)O(2), the acetohydrazide group is almost planar [within 0.0306 (12) Å] and forms a dihedral angle of 12.15 (14)° with the benzene ring.
