conclusions considering the personal and background characteristics of personnel and understanding their association with stress and stressful situations encompasses the ability to persevere and adapt to contextual stressors. patients and methods in this cross-sectional study, 3643 anonymous questionnaires were disseminated among nurses in different hospitals in tehran, iran, by utilizing multi...

medication errors account for about 78% of serious medical errors in intensive care unit (icu). so far no study has been performed in iran to evaluate all type of possible medication errors in icu. therefore the objective of this study was to reveal the frequency, type and consequences of all type of errors in an icu of a large teaching hospital. the prospective observational study was conducte...

in this paper, we analyze the dynamics of income gap between 138 countries with usa by using time series model of convergence hypothesis and various panel unit root tests over period 1950-2008. all panel unit root tests don’t reject the null hypothesis of unit root. univariate unit root tests results show that gdp per capita of south korea, switzerland, austria, lesoto and hungry catch up with ...

Structural health monitoring is a broad field that encompasses a number of synergetic technologies brought together to provide a system that can potentially identify and characterize the performance and/or possible deterioration of a structural system. Such a system would include a data acquisition subsystem capable of recording a structure’s response to ambient and external loads and computati...

1. Abstract This research develops a new structural optimization method for foldable motion structure with repeated rigid-body mechanism cell. Compared with conventional rigid-body mechanism, there are many kinematic advantages of a motion structure as it can achieve large shape transformation for real applications such as satellite solar panels, space antennas to shelters, and swimming pool co...

Lactoferrin (LF) and β-lactoglobulin (BLG) are among the protein pairs that exhibit heteroprotein coacervation, a unique and relatively unexamined type of liquid-liquid phase separation (LLPS). In prior work we found that LF and BLG undergo coacervation at highly constrained conditions of pH, ionic strength and protein stoichiometry. The molar stoichiometry in coacervate and supernatant is LF :...
