Electrokinetic (EK) remediation is a promising technology for soil decontamination, although basic pH in the close to cathode has constrained EK effectiveness due heavy metal precipitation. This study aimed enhance copper removal from kaolinite by integrating with compost (C) as recyclable reactive filter media (RFM) first time. Compost placed near served an adsorbent bind ions while buffering ...

The high-precision geometric positioning of optical remote sensing satellites is the prerequisite to determine application capability satellite image products. Its accuracy related observation each link in imaging process, including attitude, orbit measurement accuracy, time synchronization camera and so on. Untimely inaccurate on-orbit calibration will lead great errors. To optimize images wit...

In this study, a new model of combining variables affecting the classification of customers is introduced which is based on a distribution system of goods and services. Given the problems that the RFM model has in various distribution systems, a new model for resolving these problems is presented. The core of this model is the older RFM. The new model that has been proposed as PRFM, consists of...

The introduction of data mining methods in the banking area due to the nature and sensitivity of bank data can already be considered of great assistance to banks as to prediction, forecasting and decision support. Concerning decision making, it is very important a bank to have the knowledge of (a) customer profitability and customers’ grouping according to this parameter and (b) association rul...

Sequential pattern mining is an extension of association rule mining that discovers time-related behaviors in sequence database. It extends association by adding time to the transactions. The problem of finding association rules concern with intratransaction patterns whereas that of sequential pattern mining concerns with inter-transaction patterns. Generalized Sequential Pattern (GSP) mining a...

Methyltransferases (MTases) form a major class of tRNA-modifying enzymes needed for the proper functioning of tRNA. Recently, RNA MTases from the TrmN/Trm14 family that are present in Archaea, Bacteria and Eukaryota have been shown to specifically modify tRNA(Phe) at guanosine 6 in the tRNA acceptor stem. Here, we report the first X-ray crystal structures of the tRNA m(2)G6 (N(2)-methylguanosin...

OBJECTIVE To increase discriminatory accuracy (DA) for emergency cesarean sections (ECSs). STUDY DESIGN We prospectively collected data on and studied all 6,157 births occurring in 2014 at four public hospitals located in three different autonomous communities of Spain. To identify risk factors (RFs) for ECS, we used likelihood ratios and logistic regression, fitted a classification tree (CTR...

This paper presented a rigorous mathematical model based on orbital parameters for correction of the geo-rectified images such as Ikonos Geo, where the geometry of image at the time of imaging is lost and minimum information regarding the satellite movement in its orbit is available. Based on this model, the geo-rectified image is converted back to its geometry at the time of imaging at first. ...
