AIM To investigate the effects of prolonging hang time of total parenteral nutrition (TPN) fluid on central line-associated blood stream infection (CLABSI), TPN-related cost and nursing workload. METHODS A before-after observational study comparing the practice of hanging TPN bags for 48 h (6 February 2009-5 February 2010) versus 24 h (6 February 2008-5 February 2009) in a tertiary neonatal i...

Spatial variability of soil fluoride in the plough layer 0~20cm of paddy soil from Hang-Jia-Hu Plain of Zhejiang Province in China was studied using geostatistical analysis and GIS technique. The results of Semivariograms analysis showed that two forms of soil fluoride were correlated in a given spatial range, and total fluoride (T-F) was controlled by intrinsic factors of parent material, reli...
