Large electric potential perturbations in PMSE during DROPPS

On the source of plasma density and electric field perturbations in PMSE and PMWE regions

تشکیل ابرهای مسسفری در فصل تابستان و در ارتفاع ۸۰ تا ۹۰ کیلومتری از سطح زمین در نواحی قطبی دارای اهمیت بسیار زیادی می باشند. ارتباط مستقیم بین افزایش مشاهده این ابرها و پدیده گرم شدن کره زمین از دلایل اصلی اهمیت مطالعه این ناحیه می باشد. طبق تحقیقات انجام شده افزایش گازهای گلخانه ای باعث کاهش دما در این ناحیه از جو می شود. از طرف دیگر افزایش گاز متان و فرایند تجزیه آن توسط نور خورشید نیز باعث ا...

on the source of plasma density and electric field perturbations in pmse and pmwe regions

on the source of plasma density and electric field perturbations in pmse and pmwe regionspolar mesospheric summer/winter echoes (pmse/pmwe) are very strong radar echoes produced by ionospheric electron density fluctuations at half the radar wavelength. the main focus of this paper is the altitude range 80 to 90 km in summer and altitude range 65-86 km in winter in the polar mesosphere . this pa...

Stress Fields and Electric Potential in Piezoelectric Cylinders

Stress Fields and Electric Potential in Piezoelectric Cylinders

Spatial changes in the transmembrane potential during extracellular electric stimulation.

The purpose of this study was to determine the spatial changes in the transmembrane potential caused by extracellular electric field stimulation. The transmembrane potential was recorded in 10 guinea pig papillary muscles in a tissue bath using a double-barrel microelectrode. After 20 S1 stimuli, a 10-ms square wave S2 shock field with a 30-ms S1-S2 coupling interval was given via patch shock e...
