Ureteral duplication is a common congenital anomaly of the urinary system observed in 0.8% of autopsy series [1]. However, bifid ureter with a blind branch is a rare condition. It is three times more prevalent in women than men and is observed twice as often on the right side as on the left side [2]. It does not generally give any clinical symptoms. However, in the literature, symptomatic cases...

Soil heavy metal pollution is one of the main environmental problems in Pearl River Delta Economic Zone of China. Based on multi-purpose regional geochemical survey, regional eco-geochemical assessment, local eco-geochemical assessment and comprehensive appraisal, the eco-geochemical survey and assessment in Pearl River Delta Economic Zone of 41,698 km2 were completed. Samples from soils were c...

Recently, high-order statistics have received more and more interest in the field of hyperspectral anomaly detection. However, most of the existing high-order statistics based anomaly detection methods require stepwise iterations since they are the direct applications of blind source separation. Moreover, these methods usually produce multiple detection maps rather than a single anomaly distrib...

Abstract Most conventional statistical methods aiming at defining geochemical concentration thresholds for separating anomalies from background have limited effectiveness in areas with complex geological settings and variable lithology. In this paper, median+2MAD as a method of exploratory data analysis (EDA) and concentration-area (C-A) fractal model as two effective approaches in separation g...

in order to assess the potential of copper mineralization and its associated elements in soltan meydan basaltic formation situated in the north of shahrud, the method of stream sediment and heavy mineral has been used. to achieve this aim, totally 68 samples of sediments (-80 mesh in particle size) and 6 samples of heavy minerals (-20 mesh in particle size) have been collected in an optimized n...

The blind-ending bifid ureter is a rare congenital anomaly of urinary system. We presented one case of the blind-ending bifid ureter which originates from the middle third ureter. The embryogenesis and possible mechanisms are reviewed. Changing positions in projections during intravenous urography provides more information of the blindending branch. Intravenous urography is one of the best moda...

A submersible analyzer (Geochemical Anomaly MOnitoring System, GAMOS-IV) powered by micro-diaphragm pumps has been developed for in situ monitoring of time-series changes in manganese concentrations. The analyzer determines dissolved manganese in a continuous manner using a H2O2-luminol chemiluminescence method. The analyzer operates with a sample and reagent flow rate of approximately 60 ml/mi...

gabal el-zeit block at the western coast of the gulf of suez region in egypt consists of two varieties of precambrian granites, namely monzogranite and a peripheral zone of alkali granite. both granitic varieties display moderate (60.1-68.5 wt%) and high silica (73.36-76.16 wt%) contents with high na2o+k2o (7.21-8.61 wt%), respectively. the investigated monzogranite is calc-alkaline metaluminou...

Central equatorial Paciic sea surface temperature (SST) anomaly is a critical predictor of basin-wide oceanographic and atmospheric eeects of the El Ni~ no-Southern Oscillation (ENSO) phenomenon. We employ two geochemical thermometers measured on coralline aragonite to reconstruct an independent proxy-based measure of central equatorial Paciic sea surface temperature anomaly. In addition, we as...
