Intensity variations of the postnoon auroral bright spots observed at Zhongshan Station, Antarctica on August 8, 1999

In this paper we use the high speed multi channel meridian scanning photometer data and all sky TV camera images to analyze the intensity variations of the postnoon auroral bright sports of 557.7 nm and 630.0 nm emissions. Several results can be obtained from this paper. (1) Bright spots are rather transient features lasting typically for only a few minutes. (2) The intensity of the postnoon bright spots of 557.7 nm emissions can surpass 11 kR. The occurrence of the bright spots seems rather frequent. (3) The ratios of I(427.8)/I(630.0) and I(427.8)/I(557.7) during the bright spots occurring time show a positive peak and negative peak respectively. It qualitatively indicates that the average precipitating electron energies along the meridianal scan above Zhongshan Station increased as the bright spot appeared. And the intensification of the spot mainly was caused by the increasing of high energy (3 10 keV) flux. (4) Usually the bright spots are accompanied with the magnetic pulsation and the occurrence of multi band arcs.

Study of“bright spots”in seismic reflection data

"bright spot" on reflection seismic profile has been regarded as one of the important indications of oil and gas,and it has been widely used in the oil and gas exploration. Moreover,with the development of new technologies,"bright spot" technique has been gradually applied to the exploration of coal,underground water and other fields,and also in the research of deep structure of the earth. Based on the reviewing of published literatures,the authors described the structural features and generation of "bright spot" on seismic profile for energy resources exploration and crustal-scale deep seismic reflection profiles,and further summarized the applications of the "bright spot"technique in energy resource exploration and deep structure research.

Bright Spot of Socialist Democracy——Direct Election at a Community in Beijing

On the morning of August 17, 2002, colorful flags and slogan streamers were fluttering over the sports ground of the Dongsi Shisantiao Primary School in Dongcheng District of Beijing. A huge red streamer "Direct Election of the Jiudaowan Community of Beixinqiao Neighborhood Community Office of Dongcheng District" over a platform told that a direct election of the community was to be held there.

Domestic Consumption Bright Spot for China's Textile and Apparel Industry in 2010

In 2009, China’s growth of national textile and apparel sales reached 20 percent, so that by 2010, domestic consumption has already become the bright spot in

New prospective gas plays in pliocene sands, offshore Nile Delta Basin: A case study from Kamose-1 well at North Sinai Concession, Egypt

The Pliocene sands in the offshore parts of the Nile Delta Basin represent significant gas reservoirs.Several targets have been recently discovered in different places along the offshore Nile Delta Basin.The present work focuses on the possibility of discovering new natural gas resources at North Sinai Concession through an integrated method between seismic and well logs data interpretations.A case study from Kamose-1 Well at Kamose Field,North Sinai Concession has been examined.The quantitative explanation for the well log data of Kamose-1 Well has revealed two zones expected to be gas-bearing zones.These intervals are located between depths;1174–1186 m(zone I)and between 1429 and 1503 m(zone II).The calculated petrophysical parameters for these zones exhibit low water saturation(24–43%),high effective porosity(30–31%),low shale volume(21–26%),high total porosity(37–38%)and low bulk volume of water(0.07–0.12).Zone II(74 m thick)shows a clear bright spot on the seismic profiles covering the study area,while,zone I is beyond seismic resolution(12 m thick).Several seismic bright spots have been outlined on the seismic data nearby Kamose-1 Well.The comparison between the newly outlined seismic bright spots with the drilled one in Kamose-1 Well exhibited a great similarity.Accordingly,these prospects are expected to be new targets for gas exploration in the Pliocene succession at North Sinai Concession.
