Nonlogarithmic Linear Titration Curves (1960)

Titration curves can be based on linear nonlogarithmic forms of the equilibrium equation of a dissociation reaction. From such curves, in contrast to those based on logarithmic transformations, both the end point of the titration and the dissociation constant can be derived.

COULOMETRIC DETERMINATION OF PLUTONIUM IN SOLUTIONS OF DISSOLVED REACTOR FUEL ELEMENTS. (1970)

Facility at HAPO. One test employed a four-rod cluster element about ten in. long and one a seven-rod cluster which was 28 in. long. In both clusters the fuel cores were 0.5 in. in dia. The fuel element cladding was either Zircaloy-2 or Zircaloy-3 and had an outside dia. of 9/16 in. and a wall thickness of 0.030 in. All fuel elements employed in the tests performed satisfactorily. One irradiated high-density UO/ sub 2/--PuO/sub 2/ capsule failed when it was inadvertently placed in a neutron flux 11 times the specified value. Except for the ruptured specimen, all pieces were in good condition and exhibited no excessive or unusual corrosion. Core- core bonding was noted on one Al--Pu alloy fuel rod and core-end cap bonding on one Al--Si-- Pu alloy rod. From the limited number of experiments and observations it was concluded that the Al-- Pu alloys, Al-- Si-- Pu alloys, and U0/sub 2/-- PuO/sub 2/ compositions tested all exhibited good radiation behavior in the ranges of interest to the PRTR. For the same temperature range (650 to 850 deg F), the Al--Pu alloys appear to be more resistant to deformation than the Al--Si-- Pu alloys. In both alloy cases, resistance to deformation tends to increase with increasing Pu content. The volume changes appear to be more sensitive to core temperature than to exposure. The cluster experiments indicate that the PRTR element design is sound and will perform well in highpressure and temperature water. The oxide specimens received exposures on the order of 1000 to 2000 Mwd/t. Grain growth was noted in one high-density piece and a central void formation was observed in two, low-density pieces. The fission gas release was up to 3% in the highdensity oxides and to about 22% in the low-density specimens. The degree of fuel core cracking appears to decrease with increasing Pu content. Capsules from these tests are currently being irradiated to higher exposures (5000 Mwd/t). The oxide capsule which failed operated in the high flux position for six days before it was removed. All of the oxide was missing and a marked core-end cap reaction had occurred. The examination of the thin-wall, extruded Zircaloy tubing indicated that all material must be carefully inspected for flaws, especially on the inner surface. It is recommended that an ultrasonic technique be employed. (auth)
Agricultural Monitoring Using Envisat Alternating Polarization SAR Images (2008)

In agricultural remote sensing, applied images should be acquired frequently enough in order to monitor important crop growth stages. Thanks to the cloud penetrating and flexible swath-positioning capabilities of space-borne SAR at present, images can be acquired even at the interval of few days during a growing season. In this study, dual-polarization (VV/VH) Envisat SAR images with high a temporal resolution were used in association with limited ancillary data to monitor crop growth and to classify crop species. It was noticed that the high temporal resolution enabled nearly continuous monitoring, but it also caused problems because of the varying incidence angles. Moreover, to carry out field surveys rapidly enough for research purposes was observed as a problem. An R 2 of 0.55 was obtained for estimating the crop growth, when average crop height in parcels was used to describe the amount of biomass. An overall accuracy of 74.7 percent was achieved for crop species classification. Envisat VH polarization appeared to be useful in the estima
A Model for the Anodic Dissolution of Iron in Sulfuric Acid (1979)

Potential and current distributions are calculated for a partially passivated rotating disk electrode. A discontinuous local polarization relation is used to reflect the change from the active to the passive state. Results of the model yield a z‐shaped polarization curve similar to curves measured experimentally by Epelboin et al. The limiting cases of mass transfer control and ohmic control are treated. Comparison of previous experimental results with the model is in harmony with the conclusion that the electrode is mass transfer controlled in the transition region.
Pressure Drawdown and Buildup Analysis in Gas Condensate Reservoirs (2002)

Abstract This paper introduces a new method to analyze pressure drawdown and buildup tests in gas condensate reservoirs producing under two-phase flow conditions. Integral method of pseudopressure is used to handle the physical properties and the phase change with pressure. The phase change is the result of the retrograde behavior of condensate fluids that occurs within the reservoir when conditions of pressure and temperature are right for it. Resulting phase change causes change in the liquid saturation thereby changing the relative permeability of that phase. To use the relative permeability as function saturation, saturation has to be known at all the times. This method, however, shows how to estimate the effective permeability of the liquid and gas phase as a function of pressure, skin factor, and the arial extent of the different regions at a given stage of the depletion. Effective permeability then can be used to project the well performance during the pseudosteady state, reserves, and well flow potential (AOF). During pressure test period, which is very short as compared with pseudostaedy state depletion, producing gas oil ratio is assumed constant. In other words oil and gas rates are held constant. In reality it might be hard to do so in a phase changing environment. So, a sensitivity analysis is performed to see the effect of the change in the producing gas oil ratio on the estimation of pseudopressure. We see steady increase in percent error in pseudopressure with increasing pressure at certain percent increase in Rp. At 8,200 psi, 10% percent increase in Rp introduces 3.96% error in pseudopressure. However, the error is 1.49% at 4,000 psi and 0.27% at 1,000 psi respectively. The error at 5% increase in Rp at 8,200, 4,000, and 1,000 is 2.13, 0.79, and 0.14% respectively. It is also observed that the amount of error in the effective gas permeability is 3% and 9% in oil effective permeability. This paper is divided in four parts. First the pseudopressure is simplified to separate the effective permeability terms. Second, well testing equations are modified in order to provide correlation for effective permeability of each phase. Third, the error in pseudopressure is determined in case over or under estimated GOR value is used. Finally, a field example is solved in a step-by-step manner to show the use of the technique.
SIMULTANEOUS TOPOLOGICAL CATEGORICAL DATA CLUSTERING AND CLUSTER CHARACTERIZATION (2011)

In this paper we propose a new automatic learning model which allows the simultaneously topological clustering and feature selection for quantitative datasets. We explore a new topological organization algorithm for categorical data clustering and visualization named RTC (Relational Topological Clustering). Generally, it is more difficult to perform clustering on categorical data than on numerical data due to the absence of the ordered property in the data. The proposed approach is based on the self-organization principle of the Kohonen’s model and uses the Relational Analysis formalism by optimizing a cost function defined as a modified Condorcet criterion. We propose an iterative algorithm, which deals linearly with large datasets, provides a natural clusters identification and allows a visualization of the clustering result on a two dimensional grid. Thereafter, the statistical ScreeTest is used to detect relevant and correlated features (or modalities) for each prototype. This test allows to detect the most important variables in an automatic way without setting any parameters. The proposed approach was validated on variant real datasets and the experimental results show the effectiveness of the proposed procedure.
Managing diet quality for Cheddar cheese manufacturing milk. 1. The influence of protein and energy supplements (1999)

The effects of supplementing cows' diets with protein and energy on milk composition and the composition and yield of Cheddar cheese were investigated. This research addresses the problems of seasonal reduction in the capacity of cheese curds to expel moisture as observed in parts of south-eastern Australia. Milk was collected from cows offered a basal diet of silage and hay supplemented with different sources and levels of dietary protein and energy. The protein supplements were sunflower, canola, cottonseed meal and lupin, and the energy supplements were maize grain, oats, wheat and barely. This milk was used to manufacture Cheddar cheese on a pilot scale. Cheese moisture content was dependent on the source and level of dietary protein and energy. Milk from cows offered the lupin protein supplements and wheat energy supplements consistently produced cheese with a lower moisture content and moisture in fat-free matter. Milk from these supplemented diets had increased casein concentrations and higher proportions of alpha S2-casein than milk from the poor quality control diet. Cheese yield was directly related to the total casein concentration of milk, but was not influenced by differences in casein composition. Supplementing the cows' diets increased the inorganic P, Mg and Ca concentrations in milk. A low inorganic P concentration in milk from cows offered the control diet was caused by a low intake of dietary P. These findings showed that changes in the mineral and casein composition of milk, associated with diet, could influence the composition of Cheddar cheese.
Characterization of the B/Si surface electronic structures (1993)

High-resolution angle-resolved core-level and valence-band photoelectron spectroscopy have been used to characterize the electronic structures of the B/Si (111)-(√3×√3) surfaces. The results have been compared with theoretic calculations and other group-III metals and Si-terminated Si (111) surfaces that share the same type of surface reconstruction. We have observed a structure evolution from B-T4 to B-S5 and finally to Si-T4 as deposited boron atoms diffuse into the substrate with increasing annealing temperature. The chemically shifted component appearing in the Si 2p core-level spectrum is attributed to charge transfer from the top layer Si and Si adatoms to the sublayer B-S5 atoms. For the Si/Si (111)-(√3×√3) surface, a newly discovered chemically shifted component is associated with back bond formation between the Si adatoms and the underneath Si atoms. A new emission feature has been observed in the valence-band spectra unique to the B/Si (111)-(√3×√3) surface with B-S5 configuration. Thin Ge layer growth on this structure has also been performed, and we found that no epitaxial growth could be achieved and the underneath structure was little disturbed.
Performance-driven design and redesign of high-speed local area networks (2002)

Although distributed computing over a network of computers has become a reality, its success mainly depends on the performance of the underlying network. In this paper, we consider the problem of designing a local area network with specified cost and performance constraints. The cost and performance of a local area network (LAN) are directly related to its topology. Using the a priori knowledge of the approximate number of users of the network and the kind of communication traffic that must be supported, the designer can optimize the design of the of a LAN for superior performance. Design decisions include the number of LAN segments, number of bridges, assignment of users to segments, and the method to interconnect the segments through bridges. In case of ATM networks, the decisions are regarding the number of ATM switches, the assignment of hosts to switches, and the way to connect switches through cross-connects. While assigning too many users to the same segment may cause large delays due to the sharing of network bandwidth, splitting the LAN into too many segments will increase the cost of the LAN. We report a greedy heuristic algorithm for local area network design. We propose an interesting method to construct good initial solutions to the topology design problem using a heuristic method which is based on the three-opt technique for solving the travelling salesperson problem. Our experimental results indicate that the heuristic algorithm finds good solutions.
Plasma studies on a duoPIGatron ion source (1977)

In an effort to develop a plasma source capable of producing a dense, quiescent, uniform plasma for extracting tens of amperes of hydrogen ions, experimental and theoretical studies on a duoPIGatron ion source have been pursued. A study of plasma generation in the duoPIGatron was begun and a discharge model was subsequently developed to explain observed source behavior. The discharge model is based on two plasmas, a cathode plasma and a PIG plasma separated by a double layer of ions and electrons, and is similar to the existing model for a duoplasmatron. This discharge model is reviewed and the importance of the double layer on plasma generation in the duoPIGatron is discussed. Source electrode modifications suggested by the model resulted in a low noise level of about ±5% and a low-denisty nonuniformity of about ±10% over a 10-cm diameter at a high hydrogen plasma denisty of roughly 2×1012 cm−3. This source has been operated reliably to produce a hydrogen ion beam of 15 A at 40 keV. Initial operation of a 20-cm source employing magnetic multipole line cusp confinement [W. L.,Stirling, C. C.,Tsai, P. M.,Ryan, Rev. Sci. Instrum. 48, 533 (1977)] has delivered a beam of 60 A at 33 keV.
Effect of Twinning on the Photoluminescence and Photoelectrochemical Properties of Indium Phosphide Nanowires Grown on Silicon (111) (2008)

The relationship between crystal quality and the properties of indium phosphide nanowires grown on silicon (111) has been studied by transmission electron microscopy, photoluminescence spectroscopy, and photoelectrochemistry. Wires with no defects and with {111} twin boundaries parallel and perpendicular to the growth direction were obtained by metalorganic vapor-phase epitaxy using liquid indium catalyst. Room temperature photoluminescence from the defect-free nanowires is approximately 7 times more intense than that from the wires with twin boundaries. An open-circuit photovoltage of 100 mV is observed for photoelectrochemical cells made with the defect-free nanowires, whereas no photovoltage is recorded for those with twins.
ASSESSMENT OF LYMPHOCYTE SUBGROUPS IN CHRONIC BRUCELLOSIS BEFORE AND AFTER IMMUNOTHERAPY (2015)

Abstract- Brucellosis is an infectious disease and it seems that it affects human immune system and can cause acute, subacute and chronic clinical features. Forty patients suffering from chronic brucellosis were studied for CD3+, CD4+,CD8+, CD19+, cells and CD4+/CD8+ ratio by flow cytometry before and after treatment with antibiotics and immunopotentiators. The results were compared with 15 healthy controls. The patients were divided into three groups: 1) antibiotic, 2) levomisol + antibiotic, and 3) treated with cimetidine + antibiotic. The results showed a significant decrease of B cells (CD19+), CD4+ T cells and CD4+/CD8+ ratio in comparison with normal subjects before treatment. In the first group, significant decrease of CD4 T cells and CD4/CD8 ratio inversion were seen after immunotherapy. The 3rd group showed the best correction of phenotype quantity. In other words, significant increase of CD4+ T cells, CD19+ B cells, CD4+/CD8+ratio and decrease of CD8+ T cells were seen with cimetidine immunotherapy.
The Effect of Particle Size Distribution on Pressure Drop through Packed Beds of Cooked Wood Chips (2005)

Abstract The pressure drop of process liquors through columns of wood chips determines the operability, efficiency and control of both batch and continuous pulp digesters and the quality of the pulp produced from them. Pressure drop was measured through columns of industrial white spruce chips (produced with a chipping head‐rig) as a function of the chip size distribution and the extent of delignification. Flow resistance depended on the porosity of the chip bed which was affected by the kappa number of the chips (which affected their flexibility) and chip size distribution, the compaction forces applied to the column, and the liquid superficial velocity. The chip beds were compressible and inelastic. Previous work from the literature using the Ergun equation to characterize pressure losses through chip beds is examined and compared with results of this work.
Long-term outcome of delirium during intensive care unit stay in survivors of critical illness: a prospective cohort study (2014)

In this group of survivors of critical illness, delirium during ICU stay was not associated with long-term mortality or HRQoL after adjusting for confounding, including severity of illness throughout ICU stay. In contrast, delirium appears to be an independent risk factor for long-term self-reported problems with cognitive functioning.
MQ-Coder inspired arithmetic coder for synthetic DNA data storage (2023)

Over the past years, the ever-growing trend on data storage demand, more specifically for "cold" data (i.e. rarely accessed), has motivated research for alternative systems of data storage. Because of its biochemical characteristics, synthetic DNA molecules are now considered as serious candidates for this new kind of storage. This paper introduces a novel arithmetic coder for DNA data storage, and presents some results on a lossy JPEG 2000 based image compression method adapted for DNA data storage that uses this novel coder. The DNA coding algorithms presented here have been designed to efficiently compress images, encode them into a quaternary code, and finally store them into synthetic DNA molecules. This work also aims at making the compression models better fit the problematic that we encounter when storing data into DNA, namely the fact that the DNA writing, storing and reading methods are error prone processes. The main take away of this work is our arithmetic coder and it's integration into a performant image codec.
