Finite-difference analysis of the atmosphere electric field distribution around a thunderstorm monomer
In this study, two-dimensional finite difference method (2D FDM) is adopted to simulate the electric field distribution around four typical thunderstorm monomers which have different heights, scales and charge distributions. This paper analyses the impact and its range of ground electric field caused by different thunderstorm monomers. This paper also gives a scientific definition and quantitative analysis for the detection range of ground atmospheric electric field meter which is a crucial tactical index. The results in this study have certain significance in theory and practical guidance for thunderstorm monitoring by using networking atmospheric electric field meters.
THE NEW INVERTED ELECTRIC FIELD MILL
The paper introduces a new inverted electric field mill. The electric field mill measures the intensity and polarty of atmospheric electric field to forecast the po tential thunderstorm and electric shock in local area. It can be used safely as a monitor of the warning in places where are likely regions for the occurrence of static electricity and thunderstorm, for example, meteorological conditions for space-flight, aviation, oil, electric power, mine and open-air stadium.
Efficacy of life skills training on general health in students
BACKGROUND
With regard to the importance of life skills, the present study deals with the effect of life skills training on general health of the students.


MATERIALS AND METHODS
This was a one-group, pre-test, post-test, quasi-experimental research. Forty students were selected through purposive sampling method. The data collection tool was Goldberg General Health Questionnaire.


RESULTS
Paired t-test showed a 22 score significant decrease in general health after education compared to before education (P < 0.01).


CONCLUSION
This study showed that life skills education increases general health level of the students.
