Nitric acid-organic mixtures surveyed for use in separation by anion exchange methods

Column elution-spectrographic analysis technique compares certain solvents directly to the methanol system, using inert rare earths instead of actinides. Distribution ratios for americium between 90 percent solvent, 10 percent 5 M nitric acid and Dowex 1 nitrate form resin for a large group of organics miscible in water was determined

An analysis of the theory and principles of alternative dispute resolution

The system of Alternative Dispute Resolution, commonly known as ADR, comprises multiple informal processes. Traditional processes of negotiation, mediation and arbitration are primary processes within the system of ADR. The elements of the primary processes have been combined with one another or with those of public process to form hybrid ADR processes original only to the system of ADR. These hybrid processes are: rent-a-judge, the mini-trial, the summary jury trial, neutral evaluation and mediation/arbitration. Under the auspices of ADR, derivative processes have also been developed, such as expedited arbitration, documents-only arbitration, final-offer arbitration and quality arbitration. Each process is distinct and separate, having its own unique form, function and method of transforming a dispute. Outwardly, this represents a diverse collection of disjunctive processes. Yet an introspective analysis shows that there is an innate centrality that originates in core principles that bind individual processes to each other and to a unified body of theory. These foundational principles of ADR are replicated in each of its processes. In these terms, ADR is therefore conceptualised as a pluralistic system of dispute resolution that consists of autonomous and individual systems of process that conform to a central body of general theory and consensual principles. As a method of extracting the fundamental principles of ADR, the discontinuities and continuities between the theory and principles of civil procedure, as a unitary system .of procedure, and ADR processes are explored. However, in its conclusions, the thesis rejects the premises of a unitary system of procedure as forming the basis for the theory and principles of ADR. Instead, the contrary notion is advanced that ADR is an independent system of dispute resolution which is based on a theory of processual pluralism and supported by cogent processual principles.Constitutional, International and Indigenous LawLL.D

Existence of the Bogoliubov S(g) operator for the (:ϕ4:)2(:\phi^4:)_2 quantum field theory

We prove the existence of the Bogoliubov S(g) operator for the $(:\phi^4:)_2$ quantum field theory for coupling functions $g$ of compact support in space and time. The construction is nonperturbative and relies on a theorem of Kisy\'nski. It implies almost automatically the properties of unitarity and causality for disjoint supports in the time variable.Comment: LaTeX, 24 pages, minor modifications, typos correcte

Characterization of non‑linear mechanical behavior of the cornea

The objective of this study was to evaluate which hyperelastic model could best describe the nonlinear mechanical behavior of the cornea, in order to characterize the capability of the non-linear model parameters to discriminate structural changes in a damaged cornea. Porcine corneas were used, establishing two diferent groups: control (non-treated) and NaOH-treated (damaged) corneas (n= 8). NaOH causes a chemical burn to the corneal tissue, simulating a disease associated to structural damage of the stromal layer. Quasi-static uniaxial tensile tests were performed in nasaltemporal direction immediately after preparing corneal strips from the two groups. Three non-linear hyperelastic models (i.e. Hamilton-Zabolotskaya model, Ogden model and Mooney-Rivlin model) were ftted to the stress–strain curves obtained in the tensile tests and statistically compared. The corneas from the two groups showed a non-linear mechanical behavior that was best described by the Hamilton-Zabolotskaya model, obtaining the highest coefcient of determination (R2 > 0.95). Moreover, Hamilton-Zabolotskaya model showed the highest discriminative capability of the nonlinear model parameter (Parameter A) for the tissue structural changes between the two sample groups (p= 0.0005). The present work determines the best hyperelastic model with the highest discriminative capability in description of the non-linear mechanical behavior of the cornea.Ministry of Education DPI2017-83859-R DPI2014-51870-R EQC2018004508-P UNGR15-CE-3664Ministry of Health - Turkey DTS15/00093Junta de Andalucia PI16/00339 PI-0107-2017 PIN-0030-201

Case report of a rare thumb exostosis

Thumb exostosis is a rare, benign, and acquired bony tumor of the distal phalanx of the thumb, the mass itself is typically painless, but pressure on the nail plate can result in pain and deformity of the involved digit. This study was conducted at King Hussein Medical Centre in Amman, Jordan. A 38-year-old male patient, medically free, presented with a right thumb ulnar aspect hard mass, and pain at that site of his thumb. He started to notice it since 1 year. On examination, a hard bony lesion around 1×1 cm in size was present on the ulnar aspect of the right thumb tip, with tight but healthy skin over it. X-ray radiographs of the hand showed a bony lesion in continuity with thumb distal phalanx ulnar aspect native cortical bone. Excisional biopsy was done from dead ulnar approach without nail bed removal was done, and histopathology result confirmed the diagnosis of thumb exostosis and no recurrence occurred either on clinical or radiological follow up till date.

Analyticity of The Ground State Energy For Massless Nelson Models

We show that the ground state energy of the translationally invariant Nelson model, describing a particle coupled to a relativistic field of massless bosons, is an analytic function of the coupling constant and the total momentum. We derive an explicit expression for the ground state energy which is used to determine the effective mass.Comment: 33 pages, 1 figure, added a section on the calculation of the effective mas

On the distribution of the Wigner time delay in one-dimensional disordered systems

We consider the scattering by a one-dimensional random potential and derive the probability distribution of the corresponding Wigner time delay. It is shown that the limiting distribution is the same for two different models and coincides with the one predicted by random matrix theory. It is also shown that the corresponding stochastic process is given by an exponential functional of the potential.Comment: 11 pages, four references adde

EFFECTS OF MAGNETIC AND NON MAGNETIC LAYER THICKNESS ON GIANT MAGNETORESISTANCE IN (NiFeCo/Cu) MULTILAYERS

This paper presents a study of the magnetoresistance (MR) in the layered magnetic structure (NiFeCo/Cu). The effect of the magnetic (m) and non magnetic (nm) layer thickness (tm , tnm) and the composition of the magnetic layer has been discussed in the framework of the Johnson-Camley semiclassical approach, which is based on the Boltzmann transport equation. Our results are compared with the experiments and seem to show good agreement. Indeed, three main features of the MR are reproduced: (i) Presence of MR peak at tmmax which vary with the magnetic layer composition, (ii) A MR decrease with non magnetic layer thickness tnm, (iii) The increasing magnitude of MR ratio with increasing Co content.This paper presents a study of the magnetoresistance (MR) in the layered magnetic structure (NiFeCo/Cu).

Dependence of magnetoresistive properties in [Co98Zr2 (25Å)/Cu/Co (25Å)] magnetic sandwiches on the Cu deposition pressure: Correlation of the “CoZrCu” disordered phase concentration and the interfacial mixed zone thickness with the Cu pressure

The magnetoresistance (MR) and the saturation resistivity (ρs) are studied versus the Cu deposition pressure (PCu) at room temperature, in [Co98Zr2 (25Å)/Cu (tCu) /Co (25Å)] magnetic sandwiches prepared by RF diode sputtering. Results of low angle X-Ray Diffraction patterns have been proved the importante interfacial degradation observed in (CoZr/Cu) multilayers, compared to the usual (Co/Cu) structures. The highest value of transverse MR is obtained along the easy axis, and the MR curve saturates in a small magnetic field of 100 Oe at room temperature. Which leads to an interesting increase in MR sensitivity about 2%/Oe. The main features of the magnetoresistive properties evolution with Cu deposition pressure are: The maximum of MR increases and moves towards larger Cu thicknesses (tCu) for increasing PCu. The saturation resistivity ρs decreases with increasing tCu while it increases versus PCu. The satisfactory agreement between our experimental results and calculated ones in the framework of the Johnson-Camley semi-classical model, allows us to interpret the MR and ρs behavior as a result of a reinforcement of the disordered phase ″CoZrCu″ inside the mixed zone whose thickness tmx increases with PCu .The magnetoresistance (MR) and the saturation resistivity (ρs) are studied versus the Cu deposition pressure (PCu) at room temperature, in [Co98Zr2 (25Å)/Cu (tCu) /Co (25Å)] magnetic sandwiches prepared by RF diode sputtering.
