Abstract One of the objectives Far UltraViolet (FUV) imager on Ionospheric Connection Explorer (ICON) spacecraft is to make high resolution images nighttime near equatorial oxygen 135.6 nm airglow emission. This emission largely product O + ion re-combination and therefore intensity a proxy for remote measurement ionospheric density. The ICON FUV instrument capable imaging night glow by viewing...

حفاری های کم عمق از جمله تونل­ها می­توانند باعث حرکت زمین شوند که این حرکت­ها به­صورت نشست در سطح زمین نمایان می­شوند. تونل­ ها ممکن است در مناطق شهری با تراکم جمعیت زیاد ساخته شوند، بنابراین نشست ایجاد شده بر ساختمان­ ها و تأسیسات قرار گرفته در بالای تونل تاثیرگذار است. به­همین دلیل تخمین میزان نشست ناشی از حفر این تونل­ها ضروری است.  عوامل مختلفی از قبیل عمق، فشار سینه­کار و فشار تزریق بر میز...

Airglow observation is a very effective method to investigate plasma bubbles, and can obtain their horizontal structure. In this study, the image processing was used process airglow data, including enhancement, azimuth correction, projection, clear products of equatorial bubbles (EPBs) were obtained. Based on optical data imager in Hainan, we investigated main features EPBs, statistically analy...

Recently, many studies have been conducted on the stratum deformation induced by earth pressure balance (EPB) shield tunneling in soft soil and sand. Movement laws vary largely among different strata. However, at present, relevant research mainly focuses sand, whereas little attention has paid to movement law of round gravel with higher instability. In this study, a field monitoring test was ca...

This study demonstrates a three-dimensional numerical simulation of earth pressure balance (EPB) shield tunnelling using coupled discrete element method (DEM) and finite difference (FDM). The analysis adopted the actual size spoke-type EPB tunnel boring machine (TBM) consisting cutter head with cutting tools, working chamber, screw conveyor, shield. For model to reproduce in situ ground conditi...

DFT(B3LYP) studies on first protonation step of a series of Cu(II) complexes of some tripodal tetraamines with general formula N[(CH(2))(n)NH(2)][(CH(2))(m)NH(2)][(CH(2))(p)NH(2)] (n = m = p = 2, tren; n = 3, m = p = 2, pee; n = m = 3, p = 2, ppe; n = m = 3, tpt; n = 2, m = 3, p = 4, epb; and n = m = 3, p = 4; ppb) are reported. First, the gas-phase proton macroaffinity of all latter complexes ...

Using state-level data, we report special education (SPED) trends in Tennessee from 2009 to 2019 for students Grades 3 8 by language groups—native English speaker (NES), English-proficient bilingual (EPB), and current learner (Current EL)—and income status (eligibility free or reduced-price lunch). The sample included 812,783 28 districts that met the risk ratio threshold set state. Results rev...

OBJECTIVE To explore ways of controlling Chrysomya putoria, the African latrine fly, in pit latrines. As pit latrines are a major source of these flies, eliminating these important breeding sites is likely to reduce village fly populations, and may reduce the spread of diarrhoeal pathogens. METHODS We treated 24 latrines in a Gambian village: six each with (i) pyriproxyfen, an insect juvenile...
