Mineral scale deposition in near wellbore regions of injection wells is one of the main challengeable issues during the water injection process, which magnifies the importance of robust models in predicting the amount of mineral scale deposition such as calcium sulfate. One of the main challenges of CaSO4 scale is in carbonated reservoirs, in which sensitive behavior is observed in related to t...

The recombination of H3 ions with electrons was studied using FALP apparatus. Reported is observation of dependence of overall recombination process on He pressure and hydrogen partial pressure at 260 K. The effective plasma recombination rate is driven by binary H3 + e and ternary H3 + e + He processes with the rate coefficients αbin = 7.5×10 cms and KHe = 2.8×10 cms respectively. The differen...

A basic two-terminal secret key generation model is considered, where the interactive communication rate between the terminals may be limited, and in particular may not be enough to achieve the maximum key rate. We first prove a multi-letter characterization of the key-communication rate region (where the number of auxiliary random variables depend on the number of rounds of the communication),...

We present a study of H3 recombination performed at liquid nitrogen (LN2) temperatures on the two lowest rotational states of this ion, which belong to the two different nuclear spin states of the studied ion. A near infrared cavity ring-down spectrometer (~1381 nm) has been used to obtain the time evolution of concentration of both states during a pulsed microwave discharge. The discharge was ...

The potential of naphthol blue–black-modified Amberlite IRA-400 anion-exchange resin for separation of heavy metal pollutants has been explored. The distribution coefficients (Kd) of metal ions in several acidic solvent systems have been studied. The effect of the dissociation constant of the solvent on the distribution coefficient of metal ions has also been investigated. On the basis of Kd va...

In this paper we present a new model for instrumenting a process on the fly. We describe a command line tool developed by our research group based on our instrumentation library, Dyninst. With this model the user no longer needs to have a full set of mutations planned out ahead of time. The command line interface allows the user to mutate a process, gather data, and generate new mutations while...

In this study, the use of the three-layer feed forward neural network has been investigated for estimating of infinite dilute diffusion coefficient ( D12 ) of supercritical fluid (SCF), liquid and gas binary systems. Infinite dilute diffusion coefficient was spotted as a function of critical temperature, critical pressure, critical volume, normal boiling point, molecular volume in normal boilin...

Introduction Conclusions References Tables Figures Back Close Abstract Introduction Conclusions References Tables Figures Back Close Abstract In this work, existing and modified activity coefficient models are examined in order to assess their capabilities to describe the properties of aqueous solution droplets relevant in the atmosphere. Five different water-organic-electrolyte activity coeffi...
