ABSTRACT
Objective To investigate the current situation of nurses' practice environment in tertiary general hospitals in Anhui Province,and to provide references for improving it.Methods The Nursing Work Index-Revised was used to investigate nurses from 35 tertiary general hospitals in Anhui Province.Results The mean score of Nursing Work Index-Revised was 64.79±26.07.The entry of hospital has a training program for newly recruited nurses,nurses in the work team are qualified for care received the highest score;the entry of the level of remuneration of nurses is appropriate in all sectors of society,nurses have the opportunity to participate in hospital internal management and nurses have the opportunity to participate in hospital management decisions got the lowest score.Whether a teaching hospital,the number of years of work,gender,education,department,title,age and whether recruited with authorized strength played important roles in nurses' practice environment.Conclusion The score for nurses practice environmental in Anhui Province was not high,and there were differences between regions.Hospital management mode and nurse salary distribution system need to be improved.Nursing managers should take appropriate measures to address existing problems and improve the nurses' practice environment according to different characteristics.
ABSTRACT
During the electroporation cell membrane conductivity increases dramatically, so the analytical model for calculating the transmembrane voltage (TMV) induced on an unpermeabilized cell membrane in suspensions can not be used in this case. An analytical model for the TMV induced on a permeabilized cell membrane in suspensions exposed to a high voltage DC pulse field was built. First, a permeabilized cell was replaced by a sphere cell having the equivalent conductivity. Then the average field inside the permeabilized cell suspensions was calculated according to the effective medium theory. Finally, based on the analytical solution for the TMV on a single unpermeabilized cell, an analytical model for the TMV on a permeabilized cell in suspensions was derived. The model shows that the TMV depends on parameters such as the external electric field, critical angle of electroporation, cell radium, conductivity of the cytoplasm, membrane and external medium, cell arrangement and cell volume fraction.
